Power tool safety device

Abstract: A highly reliable and inexpensive safety device for a power tool having a protective guard over a cutting blade which prevents use of the power tool when the protective guard is not in place. The safety device includes a proximity detector detecting a distance between the guard and a power tool table top and an interlock system that prevents operation of the power tool when a distance less than a predetermined relative proximity is not detected. In the case of a power table saw a pair of magnets are secured to the guard and a pair of reed switches are mounted beneath the table top to be closed when the guard is in place. The interlock system responds to the reed switches by allowing the saw to be started when the switches are both closed and preventing startup when they are not. A key activated bypass circuit allows the saw motor to be started when the guard is not present.

Personal security system with guard tour features

Abstract: A personal security system including features for monitoring guard tours and other surveillance by security personnel. The security system includes a plurality of hand-portable transmitters, a plurality of fixed receivers and a control station. The transmitters are actuated to emit radio frequency signals including a class code that identifies first and second sets of the transmitters. The first set is assigned to security personnel and the second set to system subscribers. The receivers decode the signals from the transmitters and provide an output representing the receiver and the received class code. The control station identifies the location of the transmission using information from the receiver output, and records the time of the transmission. If the class code represents a security-assigned transmitter, the control station reports the information as a security function, such as a guard tour. If the class code represents a subscriber, the control station initiates actions appropriate for a subscriber transmission.

Guarded surgical scalpel

Abstract: A surgical scalpel (100) is provided with a retractable guard (107) for its cutting blade (106). The guard (107) is mounted on the handle (101) of the scalpel (100) for sliding movement between an advanced position in which the blade (106) is covered and a retracted position in which the blade (106) is exposed. The guard (107) may be moved with one hand, and without requiring the surgeon, nurse and/or assistant to take his or her eyes away from the patient or the instrumentation during a surgical procedure. A two-position resiliently-biased manually-releasable detent means (113) is provided between the handle (101) and the guard (107). A closed longitudinal slot (122, 123) on the guard (107) cooperates with a pin (121) on the handle (101) to limit the sliding movement of the guard (107) independently of the detent action therebetween and accommodates the mechanical loading forces. Preferably, the guard (107) comprises an inverted U-shaped channel member telescopically mounted within the hollow handle (101) for sliding movement therein.

Method for store rounding and circuit therefor

Abstract: A method and circuit for store rounding a number wherein the guard bit and least significant bit of the number are selectively exchanged depending on the IEEE rounding mode to simplify the decision-making circuit. Zero detection logic is performed on the guard, round and sticky bit positions to determine if incrementing is required. An incrementer provided with the number and a guard bit, which may be the true guard bit or a predetermined constant value depending on the rounding mode, responds to the zero detection logic to increment the number from the guard bit position.

The Praetorian Guard

Abstract: The Praetorian Guard of Imperial Rome was the power behind the throne, with the ability to make or break an emperor. As the main body of troops in Rome, they were the emperor's instrument to discourage plotting and rebellion and to crush unrest. The emperor's most immediate line of defence, they could also be his most deadly enemies. This book details the organization, dress and history of the Praetorian Guard from the time of the late Republic to the Guard's effective destruction at the battle of Milvian Bridge in AD 312. Numerous illustrations vividly depict the uniforms and weaponry of this elite fighting unit.

Crime and Control

Abstract: Three youths, one armed with a pistol, broke into a house in an expensive area of Johannesburg in October 1992. One of them was shot dead. He was killed by a pump-action shot-gun fired by the security guard: a scene reminiscent of numerous others down the decades. What was unusual on this occasion was that the wealthy house-owners were black and the robbers white. This took the police somewhat by surprise. They allegedly pulled a gun on the house-owners, thinking them part of the gang, and when they discovered that the dead man was white and the security guard black, they charged the guard with murder.

Abstract: The invention comprises a guard against storm conditions and hail, for example for passenger vehicles, and is characterised by a double-walled, inflatable covering tarpaulin and guys with attachment means (hooks), the tarpaulin being of a thickness which, on the one hand, cushions the impact of hailstones or falling branches and, on the other hand, permits the upper outer contours of a vehicle to be covered, and which can be inflated in the shortest possible time by means of an inflating device (for example a gas cartridge).

Guard for portable circular saws

Abstract: A portable, circular saw is disclosed. It includes a saw blade selectively rotatable about an axis of rotation to a define a working plane normal to such axis of rotation. The saw also includes an arcuate outer guard fixedly mounted about one side of the blade, and an inner guard having a central opening concentric of the axis of rotation. The purpose of the central opening is to permit the inner guard to be rotatably mounted about an opposite side of the blade. Also attached to the inner guard is a bulbous member that includes a leading edge that is adjacent to the cutting path of blade vis-a-vis a wooden member. Such wooden member generates a force on the inner guard as the former makes contact therewith and wherein the inner guard undergoes rotation about the axis of rotation. The bulbous member aids in the occurrence of such rotation by the fact that it substantially increases the engaging extent of the inner guard by a factor of at least 2 whereby jamming of rotation of the inner guard is prevented irrespective of position of the wooden member with respect to the inner guard.

Warning device for distance between vihicles

Abstract: PURPOSE:To provide a warning device for the distance between vehicles preventing erroneous warning due to a guard rail along curved road and on interrupting vehicle. CONSTITUTION:A guard rail along a curved road is judged to be an object which changes from a stopped object to a moving one (travelling vehicle). If it is treated as a moving object just after the change, an erroneous warning can be issued by a slight approach to the guard rail. In the case of interruption of a large vehicle, the side is detected and erroneous warning can be issued changing from an unidentified object to the moving one. But, by the processing of the steps 444 and 446, in a prescribed waiting time, it is judged to be a guard rail or an interrupting vehicle and no warning processing is performed. When it is really 9 curve of guard rail or an interrupting vehicle, the normal recognition is get back during the waiting time and the erroneous warning can be prevented.
