Abstract: A scent dispensing device comprising a scent impregnated pad of which the side edges are supportingly engaged by the inner side surfaces of a perforated hollow tubular body within which the pad is enclosed. The tubular body is expandable between: (1) a flat-folded, collapsed condition in which a pair of opposing tube wall panels with spaced apart apertures are joined together along their opposite side edges and (2) a dilated condition in which the opposing wall panels bow outwardly of each other creating a tubular body of lenticular cross section of lesser dimension between the wall panel joined side edges than in the flat-folded, collapsed condition. Convex contoured end closure flap members connected to extend across the width of each opposing wall panel at their ends are displaceable inwardly of the opposing wall panels to close the tubular body and establish the dilated condition. The width of the impregnated pad is substantially that of the lenticular lesser cross sectional dimension.

Abstract: A pair of pivotable arms in a clamp in a personal trainer may be spring biased to a closed position as on a door frame. A lock retaining the clamp in the closed position includes a member manually actuatable to release the clamp from the door frame. A clasp on the clamp holds a first belt in a wrapped and frictional relationship. In one embodiment, the second end of the first belt is retained by a resistance unit which is disposed on a handle adapted to be manually gripped by the user. The resistance unit has bars which receive the belt in a frictional and tensioning relationship to retain the belt. Collars on the handle retain a harness shaped to envelope the user's face. The harness may be moved or rotated relative to the handle to exercise muscles in selective portions (e.g. neck or back) of the user's body. In another embodiment, a second belt engaged by the resistance unit extends beyond the resistance unit.

Abstract: A doll contains a fabric fastener, such as "Velcro", on the backside, simulating a backbone. A turntable holds the doll in upright position with arms uplifted. A consecutive series of garment sections, each depicting a separate article of clothing, is spooled onto a rotatable cylinder, spaced from the turntable, with the front end section of the spooled garment containing a complementary fabric fastener connected to the fabric fastener on the doll's backside. By rotating the doll about its vertical axis an article of clothing is dispensed from the cylinder and is wrapped about the doll's torso to dress the doll. The doll's clothing is effectively changed by rotating the doll further to dispense the next article of clothing and wrap the latter in overlying relationship with the first article of clothing about the doll's torso. This action may be continued for as many different articles of wrap around clothing as is contained on the cylinder.

Abstract: Medical infusion apparatus comprises a housing in which a standard flexible liquid reservoir is disposed. A constant-force spring applies pressure to the reservoir to force liquid out of the reservoir and along a conduit to a patient. The spring is energized by the opening of a lid of the housing which permits replacement of the reservoir.The liquid flowing out of the reservoir passes through a molded conduit part which is configured so that it is positioned at a predetermined location with respect to a flow monitor. The flow monitor injects a pulse of heat, and detects the rate at which the heat pulse travels along the conduit. A microprocessor uses the sensed flow rate to control a stepper motor which regulates fluid flow by squeezing the conduit via a spring-biased member. The apparatus has active and standby modes in which the monitor is operated respectively more and less frequently.

Abstract: An arm rest assembly is usable with a mouse pad or keyboard and provides vertical support for a user's arm to avoid fatigue and injury. The assembly has at least one forearm cradle and a thin profile which allows a mouse or digitizer pad to be placed on an assembly platen or to insert the assembly under a keyboard and support both forearms of the using while striking the keys of the keyboard with both hands. The assembly further includes a detachable slide which is pivotable and, at the same time, allows linear movement of the arm toward and away from the assembly. An interchangeable cradle for the user's forearm has springs to counteract the arm weight and to make the cradle stable in the horizontal position while permitting some tilting.

Abstract: An improved display device, which includes an enclosure having first and second opposing planar sections each having at least one opening formed therein. A plurality of elongated spools are mounted inside the enclosure, a first pair of the spools being disposed at opposing each of the first planar section and aligned along a plane parallel to the plane of the first planar section, a second pair of the spools being disposed at opposing ends of the second planar section and aligned along a plane parallel to the plane of the second planar section. The spools have upper and lower belt engaging devices. A motor is operatively connected to at least one of the spools. Upper and lower endless belts operatively engage the belt engaging devices and sequentially connect the plurality of spools, effecting simultaneous rotation thereof.

Abstract: An improved toppling toy is characterized by a resetting capability that comprises a plurality of finger tip operated actuators, each of which is associated with and coupled to an associated one of the pivotally mounted tiles for joint pivotal movement therewith; and each actuator contains an outer actuator surface exposed on the upper surface of the track to a players finger, such outer surface having a frictional characteristic, whereby dragging movement of the players finger along a finger dragging lane on the track and across and transverse the actuator when the tile is in the down position causes pivoting of the actuator and thereby uprights the associated tile. Suitably the actuator and tile are formed in a unitary one piece structure of molded plastic material. A novel track contains rods to serve as a pivot for the tiles and is also formed of a unitary one piece assembly of molded plastic material.

Abstract: A children's toy car playset contains at least two toy cars, suitably containing low friction wheel and axle structures. Each of the cars contains an anti-collision device that in normal play prevents collisions between the cars, irrespective of the angle of approach at which one of the cars moves toward an other. Suitably the anti-collision device is formed by a permanent magnet with the magnetic fields oriented so that the field lines extend downwardly at least about the periphery of the car.

Abstract: A guide device designed to hold an arrow on its rest under all conditions of hunting and shooting a bow is disclosed. The device is held to the bow by a screw through its mounting bracket and into the rest or berger button hole in the side of the bow. The guide device has two guide arms which hold the arrow in place and a trigger to open the arms when the archer is ready to shoot. A spring is attached to the arms for closing the arms and returning the trigger. The arms are also shaped on top to allow faster and easier arrow placement when loading. After loading an arrow, the arrow is held on the rest and is ready for shooting. After making a full draw of the bow, the trigger is pulled with the index finger and the arms move away to let the arrow pass freely. After the shot, the trigger is released and the spring closes the guide arms. The guide arms can be easily bent to accommodate shorter arrow shafts and front mounted bow sights.

Abstract: On the vehicle are mounted an actuation member, a force transmission unit and a drive element. Preferably, the actuation member is comprised of two levers, each of them being fixed to a metal cable each connected to a chain, the two chains actuating the wheels of a gear-box. The latter acts on the drive element which sets in motion the vehicle. A sliding seat enables to transmit the maximum of muscular power to both levers. One or a plurality of free wheels transform the reciprocating motion of the levers into a unidirectional motion for the drive element. With this vehicle, it is possible to optimally transform the muscular energy into driving power.
