Medical needle puncture guard

Abstract: A small protective guard rides on the shaft of a needle. After the needle has been inserted into a patient to deliver or withdraw fluids, the guard is positioned to form a protective barrier crossing in front of the needle tip. The guard is fashioned to collapse inward in front of the tip when its front portion is advanced past the needle tip. The guard carries sharp blades that engage the needle shaft and prevent the guard from moving forward off the needle once the device is activated. An optional manually operated trigger mechanism deploys the guard automatically.

Hospital bed with guard rail actuated safety apparatus

Abstract: Guard rail actuated safety apparatus (42, FIG. 1; 89, FIGS. 5A and 5B) is operative to prevent simultaneous lowering of both of a pair of guard rails (26, 28) to inoperative positions in which they are ineffective to prevent a patient from falling off the edge of a patient support assembly 12. In one embodiment, the guard rails are secured together by a cable (44) which holds the guard rails against concurrent lowering. In an electromechanical embodiment, a controller (89, FIG. 5) senses the guard rail (26, 28) position, and blocks the lowering of either guard rail (26, 28) whenever the other is lowered. In addition, or alternatively, the controller (89) actuates a brake 146, sounds an alarm (136), raises the guard rails (26, 28) after a time delay (158), deactuates a drive motor (118) for a movable or adjustable patient support assembly (12) or releases air from a pneumatic mattress (12A'). An attendant detector (141, 143, 138, 140 ) overrides actuation of the selected alarm condition responsive apparatus (146, 148, 150, 152, 154) and rail latch actuators (93, 95, 91, 97) when an attendant is detected alongside the bed (8).

Needle guard device

Energy absorbing guard rail terminal

Abstract: An improvement to an energy absorbing guard rail terminal for use on longitudinally extending roadways. The energy absorbing guard rail terminal having a number of overlapping horizontally extending parallel guard rails positioned on oppositely disposed sides of a plurality of longitudinally spaced break away posts with the upstream ends of the guard rails secured to the post. Splice bolts connect the overlapping ends of adjacent rails which are characterized by a plurality of openings within each horizontal rail aligned with the splice bolts whereby the impact of the vehicle on the upstream end of the rails will force the bolts to shred out the rail material between the openings within the rails. By absorbing the kinetic energy of the impacting vehicle, the collapseable guard rail terminal allows for safe deceleration of the vehicle upon impact, avoiding serious injury to the driver.

Blade guard system for rotary saws

Abstract: A blade guard system for power driven rotary saws having a drive shaft arm rotatable between inboard and outboard cutting positions relative to the chassis, a blade guard disposed about a portion of the saw blade and rotatably attached to the saw blade shaft. An arcuate track slot is disposed on the inner wall of the blade guard adjacent to the drive shaft arm. A blade guard adjust arm is pivotally mounted at one end to the drive shaft arm and the other end of the blade guard adjust arm being releasably attachable at selected locations along the track slot to position the blade guard in desired protective positions. When the blade guard adjust arm is released from the track slot, rotation of the blade guard and the blade guard adjust arm to selected protective positions is permitted without the need to remove the blade guard or blade from the saw blade shaft. The construction and arrangement of the adjust arm, blade guard and track slot provide for improved resistance to fatigue failure of the blade guard as well as facilitating the change from inboard to outboard operating positions.

The Development of the U.S. Security Industry

Abstract: The security services industry has developed along three distinct lines: alarm, armored car, and security guard services. Guard services also include private investigative services. As a whole, the industry today is nonmonopolistic and competitive in meeting society's perceived need for greater protection. The industry may need greater help from law enforcement in assuring that prospective employees are fit to be hired. It may also require further legislation to ensure higher standards among the disparate companies.

Dragon Operations: Hostage Rescues in the Congo, 1964-1965 (Leavenworth Papers, Number 14)

Abstract: : For the Belgian Paracommando Regiment, the Congo was a familiar, though often hostile, environment. For most of the officers and sergeants of the regiment, the fields, buildings, and river below were as familiar as the Belgian landscape. But for most of the 340 enlisted men drifting in the sky over the airfield, the Congo was an unknown menace outside their military experience. Most of these paras were young draftees to whom the Congo represented a closed chapter in Belgium's colonial history. Yet even with the experience of its senior leadership, the Belgian Paracommandos faced a severe test on this early spring morning. The young paras and their seasoned leaders were conducting the first international hostage rescue in the post-World War II era. The challenge was enormous, the risks staggering; the Paracommandos were jumping into a perilous den of uncertainty. Stanleyville was at the heart of the Simba Rebellion and the scene of the growing desperation. Faced with a government ground assault, the Simba leaders had taken several thousand non-Congolese hostages to guard against what appeared to be imminent defeat. Keywords: Military operations.

Safety gate apparatus

Abstract: A safety gate apparatus for use in association with a main guard rail 14 e.g. for a mezzanine floor 10 comprises a movable gate member 15 of generally L-shape, including guard rail sections 16, 17. The gate member is pivoted about axis 20-21 between a first position in which guard rail section 16 closes a gap in the main guard rail 14, and a second position in which guard rail section 17 is parallel to, but spaced from, main guard rail 14. This position defines, with fixed side rail section 18, an enclosure forming an indent around the gap in the main guard rail, into which goods can be lifted from a lower floor.

A paradox of confirmation

Abstract: Two out of three prisoners, a, b and c, are to be exiled, while the third goes free. The choice of the two has been determined by a fair draw, of whose outcome they are ignorant. Prisoner a is keen to find out his fate, and attempts to question the guard, who knows the result of the draw. Knowing that at least one of the other two prisoners will be exiled, a asks the guard to tell him a name, either b or c, of a person who will be exiled. The guard, who is forbidden to converse with the prisoners, refuses to be drawn out. However, a, who is an amateur probability theorist, reasons to himself as follows: "If the guard had named b, I would have concluded that my chance of being freed was 1/2. If the guard had named c, I would have reasoned analogously. Either way, my likelihood of being freed is 1/2." How has this thought-experiment raised a's probability of freedom from 1/3 to 1/2?1 When faced with such a paradox, one possible strategy is to embrace its conclusion, and endorse a's reasoning. We would then have to expose the error in the initial distribution of probabilities, drawing, perhaps, on some subtle feature of the story. However, the existence of the guard is merely a narrative embellishment. Indeed, we can imagine the prisoner reasoning about a hypothetical guard, and it is hard to see how the a priori distribution of equal probabilities to each prisoner's going free given the knowledge that their fate is to be decided by a fair draw can be faulted. The guard, whether hypotheti? cal or real, can make no difference. Worse still, analogous reasoning can be used to undermine the very possibility of assigning probabilities. To see this, we begin by suppos

Arm-knee and leg guard for desks and file cabinets

Abstract: A retractable body guard assembly for preventing injuries to users and occupants caused by striking protruding edges and corners of open drawers of furniture. The body guard assembly includes a continuous band of resilient material covering the protruding surfaces of a furniture drawer and an associated track system mounted to the furniture frame and adapted to receive and guide the lateral sections of the band of resilient material. This assembly allows rectilinear displacement of the protective body guard and effectively provides cushioning against impact when the drawer is displaced in an open position.
