Abstract: A device for monitoring medication of a patient and for prompting the patient into certain medication taking schedule and/or certain programming steps and routines. The device has a plurality of compartments, each of which may store medication and an electrical signaling system to emit medication alert signals from time-to-time, each of which the signals indicates (a) that medication should be taken, (b) from which compartment the medication should be taken, (c) and the quantity of medication to be taken. If a designated compartment is not opened and closed within a predetermined period of time, the electrical signaling system will sound an alarm. If each designated compartment is opened and closed, the take-medication signal and the alarm (if operating) are turned off and the event is recorded for later review. The device includes a display having a substantially continuous display area having portions thereof closely adjacent to each compartment.

Abstract: An apparatus is disclosed which aids in the feeding of a baby while the baby is placed face-up on a substantially planar feeding surface to various levels of a sitting up position of approximately 45.degree. in angle. The feeding apparatus is a triangular inflatable support system comprising of two straps which encircle the chest under the arms of a baby for securing the entire apparatus to the baby, a strap to secure the bottle to the feeding apparatus and a valve element which inflates and deflates the hollow triangular chamber with air for the purpose of raising or lowering the height of the bottle to control the flow of the liquid into the mouth of the baby for proper feeding. While the primary object of the disclosed invention is for the feeding of a baby, this device can be used by any person who cannot hold a container because of any physical or mental impairment that would limit one's ability to feed oneself.

Abstract: Two arm sections are interconnected by a connection to provide an articulated arm. The connection includes mating gear wheels with one such wheel on each of the two arms. The connection also includes side pieces for providing a fixed distance between the respective axes of the gear wheels. The side pieces include an extension which constitutes a lever. As the angle between the sections of the articulated arm, varies the lever moves to increase or decrease the tension in a spring that counterbalances the varying forces on the articulated arm.

Abstract: A hydraulic axial piston pump has a rotating cylindrical barrel which defines pumping chambers and pistons reciprocating in the pumping chambers. A swash plate controls the length of travel of the pistons. During a part of each rotation of the barrel a piston will draw fluid into its complementary pumping chamber and during another part of each such rotation the piston will force fluid under pressure out of its complementary pumping chamber. Each chamber has an inlet valve which is closed when the pressure in the chamber exceeds the inlet pressure. Each chamber also has an outlet valve which is closed when the pressure in the outlet exitway exceeds the pressure in the chamber. High pressure fluid from the chambers is fed to shoes that ride on the swash plate to provide a fluid cushion between the shoes and the swash plate thus reducing friction.

Abstract: A security system, particularly for a vehicle, comprises an electrical security key usable to make circuits which either directly, or through relays controlling other circuits, render operable electrical devices necessary for the starting of the engine of the vehicle by a conventional ignition key and switch. To confuse a person attempting to breach the security, conductors necessary to supply power to the devices are made discontinous within a wiring loom of the vehicle and other conductors are tapped-in at sides of the discontinuities and extend to relay contacts operable by the use of the key. Further to confuse such person, further conductors are connected to other relay contacts but have no operating function.

Abstract: A clip is provided for holding an elongated flexible element. A typical elongated flexible element is an electrical power cord. The clip has a body member having two parallel projections. The power cord may be inserted in the slit between the projections. A power cord in the slit is pinched between the projections. The body member has sockets near each of its ends and a beaded cord has enlargements that fit in the sockets, respectively. The beaded cord can be stretched as it encircles a bundle of wire. When the enlargements on the beaded cord are inserted in the sockets the bundle of wire is held in place.

Abstract: A double drop trailer has a central storage or cargo section whose floor is at a lower level than the floors of the front and rear storage (cargo) sections. A first lift having upper and lower cargo platforms is located in the central cargo section, and a second lift is located in the rear section. The first lift is initially positioned so that its lower platform is level with the floor of the front section. Cargo is then moved through the rear door, through the rear section, across the lower storage platform of the first lift and placed on the floor of the front section. More cargo is then moved through the rear door and placed on the lower storage platform of the first lift. The first lift is then lowered. Additional cargo is then moved through the rear door onto the second lift and this lift is thereafter raised permitting this cargo to be placed on the upper storage platform of the lift. Finally, more cargo is moved through the rear door and loaded into the rear section of the trailer.

Abstract: A percussion instrument employs a horizontal surface whose dimensions are about 1 foot.times.2 feet.times.3/8 inch made of oak. This piece of oak has transducers on its under side and is spaced one or two inches above the floor. The percussionist sits on a stool where he can tap this piece of oak with the heels and toes of his shoe. Mounted at an elevation and position within easy reach of the percussionist are a number of tubular drums which the percussionist may strike with a drumstick. These tubular drums are about two inches in diameter and each of them has a central cavity in which a transducer is located.

Abstract: A clip for holding elongated devices such as wire, rope, tools such as screwdrivers, is provided. The clip is in two pieces. One piece is a flexible elastic elongated member with a series of spaced-apart beads near one end. The other piece is a molded plastic device having a base that has provision for attaching the base to a wall, post or pipe. Four side walls project from the base. Two opposed side walls have V-shaped cavities in them for receiving the elongated device. The beaded elongated member extends between the other two walls. The spaced beads enable the elongated member to be placed under tension as it crosses over the elongated device. The elongated member presses the elongated device toward the base and toward the walls of the V-shaped cavities. Thus the elongated device is held firmly in the clip.

Abstract: Apparatus is provided to shoot both arrows and slugs. A crossbow has a longitudinal groove for guiding a feather of an arrow being shot by the crossbow. An attachment may be added to the crossbow to enable the crossbow to shoot slugs. When the attachment is used two longitudinal grooves cooperate to form a bore to guide the slugs.

Abstract: A gyroscope is firmly held against the back side of the human hand to reduce or eliminate the effect of naturally occurring tremors such as essential tremor or other tremor. The gyroscope is driven by an electric motor energized by batteries. The batteries are mounted near the periphery of the gyroscope to enhance the gyroscopic action. In a modified form of the invention the motor is not mounted on the back side of the hand but is a separate unit to which the gyroscope can be readily coupled and uncoupled.

Abstract: A light metal piston for internal combustion engines has a pair of inserts on the inside of upper piston skirt made of a material of lower thermal expansion coefficient than that of the light metal, such as steel. Each insert has a pair of bands which are joined by a connecting portion of the insert in the region of the gudgeon pin boss. Each band extends circumferetially away from the gudgeon pin boss, so as to control thermal expansion of the piston skirt. A free end of each band are bent inwardly, so that the insert can be set firmly on the mold core of the piston during casting operation by snapping the bent portions of the insent into the grooves on the mold core.
