Abstract:
A token for use in a vending machine consists of a plastic card having at least one pair of side-by-side holograms embossed thereon. A token reader includes means to guide a token into the path of a readout beam. When two photodetectors positioned at predetermined spaced locations receive equal-amplitude first order beams from an illuminated pair of holograms, an electrically-operated plunger in the token reader operates to obliterate the pair of holograms on the token, and then a signal from a third photodetector in the token reader enables an output signal for operating the vending machine.
Abstract:
The present invention concerns a neutron dosemeter particularly applicable to the dosimetry of fast neutrons. According to the invention there is provided a composite detector material consisting of at least two fissile elements, the fission cross-section versus neutron energy response curves of which combine to match the kerma versus neutron energy response of a known biological material.
Abstract:
Each one of three filters, corresponding to different primary subtractive colors of a color picture, is embossed as a relief pattern on the same side of a plastic film within a separate one of any three of four side-by-side regions into which the film is divided. This permits the film to be thrice-folded to both (1) superimpose the three filters substantially in registration with each other and (2) place the embossed side of the film within the interior of the thrice-folded film where said filters are protected.
Abstract:
A decorative device adapted for securing to a shoe lace attached to a shoe, wherein the device includes: a body selected from the following group shapes when viewed from a top view: ovoid, kidney bean, cigar, square, or circular; wherein the device includes at least an upper surface joined a lower surface wherein the lower surface is relatively flat and adapted to engage an upper contacting surface of the shoe, when in use; and wherein the device includes a bore in the direction of the longitudinal axis of the device.
Abstract:
A standard audio cassette may be employed to provide various types of binary-coded video information, such as alphanumeric symbols and graphic elements, for display on a standard television receiver and also provide analog audio information as respective first and second components of a single composite signal applied to a suitable adaptor for inter-relating an external standard cassette player with a standard television receiver. The present invention is concerned with various improvements in the cassette recording and the adaptor. These improvements include (1) a cassette recording for simultaneous transmission of both binary-coded video information and analog audio information over a single channel, and improved coupling means in the adaptor which is responsive to such simultaneous binary and audio transmission; (2) improved coupling means in the adaptor for preventing the switching between sequentially transmitted analog audio information and binary-coded video information from being heard as audio clicks; (3) improved means for translating binary-coded alphanumeric video information which compensates for the limited video bandwidth of some standard television receivers, and (4) an improved graphic display capability, in addition to the conventional alphanumeric display capability, of a display provided on a standard television receiver.
Abstract:
A sheathing product having a structural substrate with two or more edges. The sheathing product also having a weather resistive barrier attached to the structural substrate prior to securing the structural substrate to a frame of a building. A part of the weather resistive barrier extends beyond an edge of the structural substrate to create a flap that allows the weather resistive barrier to be attached to an abutting sheathing product.
Abstract:
An article such as a plastic credit card contains concealed identifying information. The information is in the form of a series of binary information bits and it is stored in an electronic serial memory. The memory is on an integrated circuit chip imbedded in the credit card with electrical connections to two terminals on opposite surfaces of the card. The stored information bits are read out from the credit card by an apparatus which supplies current to the terminals to energize readout from the serial memory. The information bits read out are in the form of sequential variations in the current flowing to the credit card which are detected and accumulated in a shift register for utilization by a display device or a computer.
