Abstract: A work of visual or sculptural art includes an image applied to a transparent substrate. The image is cut on or into the substrate, and is highlighted by a contrast or color-enhancing backing. The work of art and method are appliable to useful articles.

Abstract: A stimulator for penile erection comprises a body member which may be inserted into the rectum of a user, the body member being so shaped as to closely conform to the topological configuration of the rectum from the anal area to a site adjacent to the prostate gland. Within the body member is electrical circuitry for generating a neurally stimulating electrical signal. Electrodes, placed at particular locations on the surface of the body member, apply the signal to the user. At least one of the electrodes closely contacts the prostate gland when the body member is operatively disposed, at a region or spot on the prostate gland previously determined to be sensitive to electrical stimulation.

Abstract: A two-wire transducer-transmitter for non-contact temperature measurement provides, in a unitary housing, a radiation sensing device producing a signal in response to sensed infrared or visible radiation, and electronic circuitry for processing the signal to provide at a two-wire output a current linerarly proportional to the sensed target temperature, on the same two wires as input power preferably in the range of from 4 to 20 milliamperes D.C. full scale.

Abstract: A dowel pin has a plurality of facets which provide numerous planes, edges and angles to constrain the dowel pin and an associated die segment to a particular orientation with respect to the base of a dental model, and to enhance the durability of the model.

Abstract: A stimulator for inducing salivation by neural stimulation comprises a housing which may be received in the oral cavity of a user, the housing enclosing electronic signal generating means and electrodes for applying a signal to neurally sensitive areas of the oral cavity to induce salivation. In its method aspect, the invention involves stimulation of salivation by the application of an electrical signal to neurally sensitive areas.

Abstract: A glove of thin, flexible elastomeric material carries electrodes, electrically connected to a connector disposed at the cuff of the glove, the connector permitting the electrodes to be electrically connected to a source of electrical energy or to a load, so that electrical energy may be applied to or drawn from living tissue.

Abstract: A package made of a flexible laminate has a heat-fusible seal of a strength sufficient to retain vacuum within the package and to withstand handling, but capable of being broken by hand manipulation.

Abstract: A supporting and transporting apparatus for a gas cylinder comprises a base, supporting and clamping structure to removably secure a gas cylinder to the apparatus, and a jacket associated with the supporting and clamping structure and with the cylinder so as to provide a convenient means for storing accessories and tools to be used with the cylinder.

Abstract: A method for determining the speed of leukocytes in retinal capillaries comprises the steps of simulating, by means of a minicomputer system which includes a visual display, the motion of entoptically seen leukocytes in retinal capillaries; observing entoptically the motion of actual leukocytes in the retinal capillaries of the subject's own eye; and comparing the appearances and motions of the visual display and the actual leukocytes. Apparatus for performing such a method comprises a minicomputer, a graphic display, and a display-processor interface.

Abstract: A rack for automobile T top inserts provides a cavity within which a pair of inserts are received and clamped, and the rack is anchored to a floor portion of a vehicle.

Apparatus for performing such a method comprises a minicomputer, a graphic display, and a display--processor interface.

Abstract: A control linkage for use with a door closer, wherein the linkage is provided with a spring which resiliently biases against relative rotation of a pair of arms as the arms approach a door-open limit position, and which aids the door closer in moving the door from the door-open limit position.

Abstract: Vehicle lifting and towing apparatus utilizes a pair of frames, each pivotably mounted to a vehicle, and having their distal ends interconnected by cable means. In one embodiment, rotation of one frame causes rotation of the other. In that embodiment, a winch remote from the frames is coupled to one of the frames, so that winching of the winch cable causes both frames to rotate about their respective axes. Means are provided in association with the other of the frames to secure that frame to a vehicle to be towed. In another embodiment, one frame is fixed in a generally vertical orientation, and a winch is mounted on that frame. The second frame is caused to rotate by operation of the winch.

Abstract: A bidirectional laser Doppler velocimeter provides absolute measurement of the speed of red blood cells flowing in individual retinal vessels. A standard retinal camera is used, and the need for a contact lens for the subject eye is eliminated. The laser beam is delivered to the eye through the fundus illumination optical system of the camera. Target fixation is done with the eye under examination. The measurements are independent from the ocular refraction; only the axial length of the eye need be determined. The instrument markedly simplifies the technique of retinal blood flow measurement.

Abstract: Power generating apparatus for conversion of radiant to mechanical or electrical energy utilizes radiometric drive rotors coupled to mechanical or electrical output devices; radiometer internal pressure regulating means controls output speed and power. Particular vane constructions enhance the radiometric effect.

Abstract: A hydraulic door closer is provided with a fluid seal for its output shaft, the seal comprising multiple O-rings disposed side-by-side in an elongated annular chamber.

Abstract: Guide means for sliding shower doors and the like includes a lower track member having a inclined upper face, an upstanding guide adjacent one edge thereof, and a guide track adjacent the other edge thereof. An outer door is guided by the upstanding guide and has a skirt which overlies it, and an inner door is coupled to and guided by the guide track, so that water impinging on the upper face of the lower track member can run off freely.

Abstract: A long dress is made up of a slip-like underdress which may be worn under a short overdress or alone, the overdress and the underdress, when worn together, providing the appearance of a long dress. The overdress and the underdress may be worn alone, however, if desired.

Abstract: An identification bracelet has a band portion and an enclosure for a likeness of the wearer having an outwardly facing transparent portion, and a closure member adapted for snap closing of the enclosure. A second enclosure is provided for other identifying indicia. The enclosures and closure members are preferably integrally molded with the band portion.

Abstract: An air lock has a chamber and a pair of doors in respective walls of the chamber. Operators associated with the doors include closers normally biasing the doors to closed positions and fluid powered openers associated with the closers capable of overriding the bias of the closers. A control system, operation of which may be initiated by initial opening displacement of one of the doors or (in one embodiment of the invention) by manually operable remote switch means, provides for opening of one of the doors and latching of the other to prevent simultaneous opening of both doors. The latch means for the doors may be overriden by direct displacement of the doors for safety purposes. The control system also triggers air handling apparatus associated with the chamber.
