Abstract: Disclosed is a system for generating six different numbers to bet in a lottery comprising a panel having six openings of the same square shape which is hand held for use with a board having building blocks containing different numbers in square spaces corresponding to the panel openings. When the openings in the panel are placed in alignment and registration with spaces on the board, no matter where on the board the panel is placed, six different numbers are always displayed. This is accomplished by a unique board numbering system and by repeated buidling blocks.

Abstract: Apparatus for self-examination of the human eye comprising a pen light for generating a beam of light, a reflecting sphere for orthogonally reflecting the beam through an opaque disc having a pin hole and a cylindrical head enclosing the reflecting sphere and opaque disc. The reflecting sphere is adjustable along its axis, and functions to reflect a uniformly diffuse beam of light through the pin hole. When the pin hole is at the anterior focus of the human eye and along its pupilary axis, a viewer can see opacities in the eye.

Abstract: A remote line printer system is used for printing on a line-by-line printer at a remote location. Data stored in a minicomputer and fed in parallel format from a print port. The minicomputer, which thinks it is driving a local printer, is connected to a microprocessor controlled transmitter which emulates the conventional minicomputer/printer interface. The transmitter includes a serializer which converts character data from parallel to serial for transmission serially to a microprocessor controlled remote receiver via a communications line. At the receiver a deserializer converts serial data into parallel format for printing by a line printer which thinks it is being driven by a local host computer. The system includes retransmission of data in case of error as well as compression of data before transmission and decompression of data before printing.

Abstract: A baker's dough proofing and raising unit includes a vessel having a vacuum siphon and water-addition mechanism for respectively extracting residual water and adding new water. A temperature and humidity adjusting cabinet is connected by flow conduits to and from the air space above the dough being proofed. A manual setting mechanism sets the desired temperature and humidity of the circulating water vapor. Audible and visual alarm mechanisms alert operators to predetermined variations of the temperature and humidity of the circulating water vapor. A preset timer controls the cleaning of the vessel by siphoning water from it and refilling it.

Abstract: Disclosed are multiple combined telephone-speaker-lamp units for use in a restaurant having a telephone ordering system. A telephone switch board permits the feeding of a telephone conversation into the audio amplifier which drives the speakers so that a telephone conversation on other phones can be played on the speakers. The lamp blinks in response to telephone ringing current fed to the associated telephone. A lever-operated snap switch is responsive to the ringing current to blink the lamp. Each combined unit has a cable of sufficient length to extend via a hole in the table supporting the unit through a pedestal and past the pedestal's base to be plugged into the central cable system and then retracted beneath the base.

Abstract: An automatic high speed microfilm searching system is disclosed for locating a desired frame of microfilm. Each frame consists of information data and index data. The index data comprises a sequence of vertically-aligned data bar groups, each representing a half character of a sequence of characters of a unique index code for the associated frame. A pair of synchronization bars, each half the width of a data bar, is vertically aligned with each data bar group. Additional synchronization pulses both precede and follow the data bar groups. Depending on which direction the microfilm is moving, the leading synchronization bars are sensed by a bar sensing unit on the left or on the right of the viewing screen. Each sensing bar unit comprises a plurality of vertically-aligned data bar sensors and synchronization bar sensors, with three sensors assigned to each vertical bar in a data bar group, and three sensors assigned to reading the synchronization bars.

Abstract: A vision testing system is disclosed in which a collimated beam of coherent light waves is passed through a transparency of an object such as a grating, a Snellen letter or a portrait to produce the diffraction pattern of the object. Then the light waves forming the diffraction pattern pass through a lens to produce the Fourier transform (the diffraction pattern) at the focal plane of the lens. A variable spatial frequency filter is positioned at the focal plane. Then the spatially filtered light waves are passed through a second lens to produce the inverse of the Fourier transform at the image plane of the second lens. That image is the spatially filtered object. By varying the degree and type of spatial filtering the resultant image can be used to test for contrast sensitivity or character (object) recognition.

Abstract: A movable thermal barrier for a two-story building having a glass wall facing in a southerly direction and comprising a thermally insulated horizontal stationary rail panel adjacent to the glass wall. A thermally insulated horizontal movable inner panel is positioned between the rail panel and the glass wall, and is movable from horizontal alignment with the rail panel to above the rail panel. A similar outer panel is positioned between the inner panel and the glass wall and is movable from horizontal alignment with the rail panel to below the rail panel. Panel mounting means supported from the building are adapted to movably support the inner and outer panels so that one may be moved above and the other below the rail panel to provide a translucent thermal barrier between the upper and lower portions of the glass wall and the inside of the building. The inner and outer panels are of similar weights so they balance each other.

Abstract: A multiple surgical cuff for introduction into a body passage such as a trachea, bladder and urethra opening or artery comprising a tubular base member encircled by proximal, distal and middle double cuff members. The middle double cuff member comprises an inflatable tubular inner cuff member encircled by a distensible tubular outer cuff member, whose wall is multiperforated at spaced points. Separate passage means communicate with each cuff member so that each can be inflated to press against the adjacent portion of the body passage wall. Another passage communicates with the space between the inner and outer cuff members of the middle double cuff member to permit the introduction of a surgical fluid such as an anesthetic in that space, so that expansion of the inner cuff member forces the fluid onto the adjacent portion of the wall of the body passage.

Abstract: A surgical cuff for introduction into a body passage such as a trachea of a surgical fluid such as an anesthetic comprises a tubular base member with an imperforate inflatable tubular inner cuff member encircling the tubular base member and a distensible tubular outer cuff member encircling the inner cuff member. The outer cuff member is multiperforated at spaced points. A sponge-like material, like sponge rubber, is positioned in the space between the inner and outer cuff members. Separate passages communicate with the space occupied by the sponge-like material and the space between the tubular base member and the inner cuff member. Surgical fluid such as an anesthetic is introduced into the space with the sponge-like material, which absorbs it.

Abstract: An improved capillary blood sampling device comprising a longitudinal body having a finger position area at one end and a longitudinal access opening to receive a spring-operated lancet holder. The lancet holder is moved longitudinally by a rotatable operating member at the other end of the body. Rotation of the operating member first withdraws the lancet holder away from the finger position area so that a lancet may be loaded while simultaneously compressing the spring. Further rotation in the same direction releases the lancet holder plunging the lancet point into the finger. When the lancet plunges into the finger the spring is compressed causing almost instant retraction of the lancet point from the finger. The finger position area may comprise a disposable platform. The lancet holder may have a ball socket adapted to receive a ball-based lancet.

Abstract: A heat exchanger core is formed from a single foil strip folded into successive U-bends to define alternate fluid passages, with even-numbered passages being for hot fluid and odd-numbered passages being for cold fluid. The folded foil thus defines three walls of each passage with the remaining fourth side open. Top and bottom plates cover and close the open sides of all the hot and cold passages respectively. The ends of certain passages remain open; the ends of other passages are selectively closed by pinching together the ends of adjacent foil walls which define the passages. A pre-formed end plate has apertures between deformable ribs; the apertures are aligned with the ends of open passages, and the ribs overlie and are joined with the pinched ends of the closed passages.

Abstract: A dental articulating forceps has a pair of opposed long thin jaws extending from and offset from interconnected spring arms. The face of one jaw directed toward the other jaw has a central groove of determined shape extending therealong, and the other jaw has a matching elongated projection adapted to be received by the groove.
