Abstract: A unitary dispensing closure having a lid mounted on a closure part or base in such a manner that the lid will automatically move toward either a closed or an opened position when it is released after being manipulated to any position between these two positions can be constructed so as to utilize the resiliency within a "live" hinge to provide the force necessary to move the lid. In any position intermediate these two positions the hinge connects to the lid and closure part or base so that contact between the lid and closure part causes temporary deformation of the hinge. As a result of the resiliency of the material in the hinge such temporary deformation is adequate to move the lid as described.

Abstract: An insulin delivery device comprised of a compartment limited by a semipermeable, ionically charged membrane, containing the enzymes glucose oxidase and catalase, is disclosed. The enclosed enzymes provide a means for varying the permeabiity of the membrane to stored insulin deposited within the compartment according to the magnitude of glucose concentration outside the compartment, thus facilitating continuous, physiologically regulated delivery of insulin to tissues. This device may be applicable for intracorporeal or extracorporeal use.

A cervical sound stop is used to ensure that only the uterus is filled with the solution.

Abstract: The process comprises injecting, before the polystyrene expanding stage, high-pressure steam into a mould which forms the definitive shape of the ribbed and grooved surface of a blank of the diaphragm. After removal of the blank from the mould, water is made to travel toward the ribbed and grooved surface of the blank by condensation resulting from a lowering of the temperature. The blank is then brutally frozen so as to produce microfractures in a thin superficial zone of the blank. This superficial zone is removed by means of a suitable machining operation so as to expose under this zone the softened aspect of the diaphragm immediately subjacent to this zone.Application in the manufacture of electrodynamic loudspeakers.

Abstract: A motor driven machine for compactly coiling a chain of sausages prior to delivering the sausages to a smoking room. The machine comprises an arcuate first arm and a second, channel-like arcuate arm; an elongated drive shaft is disposed within the second arm. A pneumatic piston joins the arms together, and conduits deliver pneumatic pressure to the piston from the bore of the drive shaft. One end of a rope of sausages is clamped to one arm, and a smoke stick is temporarily retained in the other arm. The piston is then pressurized to force the arms apart, and the drive shaft and the arms are rotated rapidly, as a unit, to form a coil of sausage about the expanded arms. When the coil reaches the desired length, the piston is then retracted so that the arms are drawn toward each other, and the smoke stick is removed with the sausages depending therefrom for processing.

Abstract: A battery operated, rotary powered washing and polishing wand is disclosed which has an elongated rigid tubular shaft and a coaxial flexible drive shaft which permits the incorporation of a bend in the shaft and the swiveling of a disc mounted at the bent end of said shaft. Fluid can be supplied through the interior of said shaft to the disc for discharge therefrom along with aspirated additives such as soap.

Abstract: A hand-held vibrating nail trimmer which facilitates the management of finger or toe nails. The trimmer contains a small electric motor which vibrates a serrated blade placed on top of the nail. The vibratory action of the blade penetrates the relatively brittle surface of the nail, thereby trimming the nail. Because of the flexible nature of the underlying skin and tissue, it will move in unison with the blade and therefore resist being damaged.

Abstract: Forced hot air alimentary oven comprises an insulated housing, vertically extending chambers situated at opposite sides of the housing, a plurality of parallel, superposed cooking compartments extending horizontally across the housing, heating elements, and a motor-driven fan for forcing the heated air throughout the housing. Relatively long and narrow passageways are defined between the open upper end of each compartment and the base of the compartment located thereabove. Pairs of spaced lips at opposite ends of each passageway act as entrance, and exit, apertures for facilitating communication between the chambers and the cooking compartments. The lips create a stream, or first zone, of rapidly moving laminarly flowing heated air that heats the food products in the superior compartment; a second, larger zone of slower moving air is utilized to heat the food products in the lower compartment. The two zoned hot air flow cooks foods with differing moisture content, such as fruit pies, evenly and thoroughly.

Abstract: A floating device, the upper or superior surface of which is designed to receive, support and at least partially protect the body surface of a swimmer lying chest-down on said device. A shell body is provided that protects, at least partially, the submerged surface of the device, as well as providing protection to other parts of the body of the swimmer, such as the arms and/or head or legs, most dangerously exposed to shocks/knocks against foreign bodies during the course of movement of the said device in the water. Further means are provided on said shell body, on the one hand in order to allow the swimmer to catch or hold himself on it, and on the other hand, eventually, to augment or increase the directional stability and steering of the device. The device is particularly adapted for use in sports activities and the descent of rivers and rapids.

Abstract: A stereoplotter with carriages and two distinct lens systems for viewing a pair of overlapping aerial photographic transparencies positioned on the carriages to produce a three dimensional optical model visible at the binocular viewer of the stereoplotter. The carriages are independently adjustable in two directions, and respond to both manual and computer control. A floating mark, or reticle, is introduced into the plane of the photographic transparency by each lens system. The operator, by manipulating manual or other controls, moves the floating marks into an apparently fused, or overlapping relationship, and then moves the fused mark along the surface of the optical model to generate a moving trace in X, Y and Z coordinates.Panoramic aerial photographs have posed significant problems for known stereoplotters, for an overlapping pair of photographs, to be viewed without distortion, required different magnification for each lens system.

Abstract: A nail polish kit comprising an outer carton, an inner display box, a unique tray that is inserted into the display box, and a retainer with cut-out slots.

Rear section includes plurality of actuators composed of strut and seat; when actuator is depressed, seat assumes horizontal position, and a large bottle of nail dress is seated thereupon. Upper extremities of caps for small and large bottles of nail dress terminate in same horizontal plane, and retainer is slipped over caps to minimize contact between adjacent bottles of nail dress.

Abstract: A mile post and mileage indicator for maintaining the exact mile post position of a vehicle while said vehicle is travelling upon a roadway containing designated mile post signs, which increase or decrease in a particular direction. This indicator may also be used to indicate exactly how far the vehicle has travelled or how much further it must travel before it reaches a certain destination. The indicator contains electronic circuits for presetting a specific mileage onto a display and for increasing or decreasing the mileage display in conjunction with a pulser unit placed in the speedometer cable of the vehicle. A calibration unit is utilized which corrects minor errors in signals received from the vehicle transmission.

Abstract: A double loop receiver used in conjunction with a transmitter broadcasting at low frequencies as a vertical magnetic dipole. The two loops are connected with their planes parallel in a resonant circuit, thereby cancelling atmospherics generated by distant thunderstorms and allowing the receiver to receive only the signal produced by the near transmitter. The loops are rotated around a horizontal axis perpendicular to the connecting line between the loops until a maximum signal is obtained. The direction of the connecting line is varied until the maximum signal shows the gradient and the direction to the transmitter. By noting the position of the loops and the loop angles with respect to the horizontal, the position of a transmitter buried in the ground can be determined. This system has particular utility in locating lost miners buried in a cave-in. Additionally, the double loop receiver concept can be used to detect subsurface ore deposits.

Abstract: A wood burning system for selectively heating one, or several, rooms in a structure, such system including a fireplace with a firebox, a chimney based on a thermal vacuum principle of operation, a combustion dome interconnecting the firebox and chimney, an inlet passage and an outlet passage defined in the bottom wall of the firebox, and a barrier situated between the inlet and outlet passage to control communication therebetween.When the barrier in the firebox is closed and a glass door seals off the open side of the firebox, the outlet passage in the firebox introduces heated air for distribution through several rooms, while the inlet passage receives the return flow of thermally spent air from the ductwork. The thermally spent air passes over the fire in the firebox and escapes up the flue.
