TL;DR: In this article, a medical line securement device holds a medical article such as a connector fitting for a catheter or a Catheter adaptor in position upon the body of a patient and inhibits axial motion of the medical article.
Abstract: A medical line securement device holds a medical article such as a connector fitting for a catheter or a catheter adaptor in position upon the body of a patient and inhibits axial motion of the medical article. The securement device includes a retainer with a base and a cover. The cover is hinged to the base such that it may be moved between an open and closed position. The base and cover each have a groove which cooperate when the cover is in the closed position to form a channel through the retainer. The medical article includes an elongated body which is received within the groove of the retainer, the elongated body lying between at least a pair of regions of larger radius of the medical article. By receiving the portion of the elongated body of the medical article between the regions of larger radius, axial motion of the medical article through the groove is inhibited. The retainer may also include one or more slots to receive any radial projections of the medical article within the retainer.

TL;DR: In this paper, an outboard motor steering system for a boat with an internal combustion engine at its upper portion and a propeller at its lower portion powered by the engine to propel and steer the boat is described.
Abstract: In an outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine at its upper portion and a propeller with a rudder at its lower portion powered by the engine to propel and steer the boat, a controller is connected to an actuator to rotate the outboard motor relative to the boat, and controls the actuator in such a manner that steered angle of the outboard motor relative to a steering angle inputted through a steering wheel becomes a predetermined ratio that is changed such that the steered angle of the outboard motor relative to the steering angle decreases with increasing moving speed of the boat. Alternatively, a switch is provided to be manipulated by the operator and generating a signal indicative of an instruction to change the steered angle of the outboard motor when manipulated; and the controller controlling the actuator to steer the outboard motor to an angle in response to inputted steering angle when the switch is not manipulated, while controlling the actuator to change the steered angle when the switch is manipulated. With this, the burdens of the operator are lightened and the steering feel is improved, in particular when the operator steers the boat to approach or leave a quay.

TL;DR: In this paper, a system for optimizing the operation of a marine drive of the type whose position may be varied with respect to the boat by operation of separate lift and trim/tilt means is presented.
Abstract: A system for optimizing the operation of a marine drive of the type whose position may be varied with respect to the boat by the operation of separate lift and trim/tilt means includes an automatic control system which stores preselected drive unit positions for various operating modes and is operative to return the drive unit to any pre-established position by pressing a selected operating mode positioning button. The various operating modes may include cruising, acceleration, trolling and trailering position, any of which may be selectively modified to accomodate changes in both operating or environmental conditions. This system may incorporate other optimization routines and/or automatic engine protection systems to provide virtually complete push button operation for complex marine drive unit positioning mechanisms.

TL;DR: A marine stern drive includes a tilt/trim and lift adjustment mechanism which raises and lowers the drive while maintaining an established trim angle as discussed by the authors, and the adjustment mechanism includes a parallelogram linkage system.
Abstract: A marine stern drive includes a tilt/trim and lift adjustment mechanism which raises and lowers the drive while maintaining an established trim angle. The adjustment mechanism includes a parallelogram linkage system. An upper lever of the linkage system is defined in part by a pair of tilt and trim actuators which vary the length of the upper linkage to adjust the trim position of the stern drive and for tilt up. A lower lever of the linkage system is defined between two flexible couplings of a propulsion drive train. One of the flexible couplings is coupled to a lower drive unit of the stern drive which permits the lower lever to rotate without changing the trim angle of the lower drive unit.

TL;DR: In this article, a motor boat gimbal controlled propelling and steering device extending through the boat wall or transom is described, where the propeller shaft and propeller are used to steer the boat.
Abstract: This is a motor boat gimbal controlled propelling and steering device extending through the boat wall or transom. In one form the power thrust is substantially in direct line with the motor shaft of the inboard motor, the motor being at about the same angle as the propeller shaft, and, in another form, a horizontal inboard motor is connected by a pair of bevel gears at a slight angle to the propeller shaft. The propeller shaft and propeller are used to steer the boat, the propeller shaft being connected to the motor shaft through a gimbal by a universal joint sealed within a tubular accordion boot so that it may swing horizontally for steering purposes and may also swing vertically to a position to at least just clear the bottom hull line and propel the boat in water just enough to float the boat. A conventional surfacing type of propeller is used to provide the optimum effect, particularly in shallow water. The propeller end of the propeller shaft is supported through a bearing box secured on the bottom of an anti-cavitation plate having a vertical fin thereabove/and below secured thereto, and a hydraulic pressure piston and cylinder are used as a trim control to vertically position the propeller, the cylinder being connected to the fin at one end and to the top of a gimbal support frame which in turn is secured externally to the boat wall or transom. A propeller shaft bearing box is horizontally pivoted to a gimbal ring, which ring is vertically pivoted in the gimbal support frame. A tiller is secured on the gimbal ring vertical pivot shaft for swinging the propeller shaft horizontally for steering, and the propeller shaft trim control lifting and depressing control pressure cylinder is connected to the propeller bearing boxes and to the tiller shaft for lifting the propeller to above the hull line.

TL;DR: In this article, a variable resistor is used to indicate the angle of tilt of a boat's stern drive, which can then be transferred to an indicator gauge to estimate the trim angle.
Abstract: A system for indicating to the boat driver the trim angle at which his stern drive is set. The system incorporates a variable resistor which is enclosed in waterproof housing. The housing is mounted on the gimbal ring or yoke at the end of the shaft which is the horizontal tilt axis. The movable portion of the variable resistor is attached to the shaft which forms the horizontal tilt axis of a stern drive. In this manner, a signal proportional to the angle of tilt of the stern drive is created and can then be transferred to an indicator gauge. A trim limit switch having interchangeable parts with the variable resistor can also be mounted on the other end of the horizontal tilt axis and connected to the power trim system to limit the angular trim position of the stern drive.
