Title: Gas discharge display apparatus
IPC: H01J17/49
Filed: 1971-05-21
Abstract: 1337174 Gas discharge display panels SPERRY RAND CORP 21 May 1971 [21 May 1970] 16194/71 Heading H1D Gas discharge display apparatus comprises a display panel having means 3 defining a cavity 4 containing an ionizable gas, electrodes 1, 6 disposed on either side of said cavity, a voltage source connected to said electrodes for establishing an electrical field across the cavity, an electrically conductive probe 8 positionable in proximity to one of said electrodes for shaping the electric field established by the voltage source, whereby the electrical field distribution produced by the electrodes across the cavity is modified by the proximity of the probe and grounding means for selectively grounding one of the electrodes on one side of the cavity in a write mode and another of the electrodes on the other side of the cavity in an erase mode. The probe has no voltage supply connected thereto but has the effect of increasing the field strength in the cavity if the side of an A.C. source connected to electrodes 6 is grounded or of decreasing the field strength if the side of the source connected to electrodes 1 is grounded, these increased and decreased values corresponding to "write" and "erase" values respectively. The probe may also be grounded, and may be magnetic if the panel supply is D.C. In the arrangement shown, the cavities 4 are provided in a layer 3 of glass or other suitable dielectric material sandwiched between front and rear glass plates 5 and 2. Electrodes 1 may be in the vicinity of, contained within or (as shown) attached to plate 2. Electrodes 6 having enlarged portions with apertures 9 aligned with the cavities 4 are similarly located with respect to plate 5 and are protected by a thin transparent non-conducting sheet 7. In modified arrangements the electrodes 6 are of uniform width narrower than the width of a cavity (Fig. 2a, not shown) or a single cavity may cover a plurality of electrode intersections (Fig. 2b, not shown). Electrodes 1 may be replaced by a continuous conductive sheet.

Title: Apparatus for the random selection and indication of information
IPC: G06F7/58
Filed: 1972-04-10
Abstract: 1386377 Random number generators A M DAVIS 10 April 1972 [19 April 1971] 16456/72 Heading G4D The Specification describes an apparatus for randomly selecting and displaying the numbers used in a " Bingo " game. An oscillator 10 operating at 100 kHz supplies pulses to 16 bistables connected as a two decade counter 11 and delivering an output in binary coded decimal. From the BCD a decoder 14 generates 90 outputs representing the 90 bingo numbers; all 90 outputs are gated by an input pulse from a gate 19. This latter is generated at a random time after the gate 19 is enabled by detecting coincidence between the pulses from the oscillator 10 and those from two oscillators 18 operating at slightly different frequencies about 1 kHz. Thus the decoder 14 delivers pulses successively to each of its 90 outputs; when one of these pulses coincides with an enabling pulse from the gate 19 it is gated to a store 15. When the store 15 is thus set it illuminates a respective lamp 17. The gate 19 is opened via gate 22 by a manual switch 23 and it is reclosed by a signal on line 21 as soon as one of the lamps 17 is illuminated so that one new lamp is illuminated each time switch 23 is operated. The lamps 17 are in an array behind a transparent panel carrying the numerals so that each lamp lights up one numeral. The enabling pulse from gate 19 is also applied to a decoding matrix 31 to gate out each numeral to an independent display 29 as it is illuminated for the first time on the main panel. In an alternative arrangement (not shown) the oscillator 10 delivers randomly occurring pulses to the counter 11. The BCD outupts are applied to stores whose states thus change continuously and cyclically. The stores are connected by normally closed gates to the decoder 14 whose outputs directly set the stores 15 to energize the lamps 17. When a switch, such as 23 is operated the gates are opened and the oscillator 10 is simultaneously disconnected. The last stored BCD output is thus applied to the decoder to illuminate a random one of the lamps. The circuit may be interposed before each lamp causing it to flash when it is newly illuminated. Several identical panels of lamps may be operated simultaneously by the apparatus.

In a rotary hydraulic pump or motor of the rotary abutment type, comprising rotary abutments 4, Fig. 3, co-operable with radially extending projections 31 on a cylindrical member 3 coaxially mounted within a cylindrical casing member 1 and wherein either the cylindrical member 3 or the casing member 1 rotates, the cylindrical surfaces of the member 3 or the partcylindrical surfaces of the abutments 4 are covered with a layer of flexible sealing material. Preferably the material is strips of oil-resistant synthetic rubber. As shown in Fig. 3, strips 6 are bonded to the member 3 with the ends of the strips inserted in slots 32 at the root edges of the projections 31. Strips 7 of oil-resistant synthetic rubber may also be bonded to the sides of each of the part-cylindrical pockets 8 in which the abutments rotate. In an alternative embodiment, Fig.4 (not shown), strips (10) of oil-resistant synthetic rubber are bonded to the abutments 4. The abutments 4 are inter-connected with a shaft 2 on which the member 3 is mounted by gearing. With five abutments and three projections, the abutments rotate at three times shaft speed. Operating as a motor with the member 3 rotating clockwise, high-pressure oil passes through a bore 47 in the shaft 2 and passages 45 to the trailing face of each projection 31 and passages 49 at the leading face of each projection exhaust the reduced pressure oil through another bore 48 in the shaft 2. The outer radial ends of the projections 31 may include strips 9 of Babbit metal to form running seals. Similarly the end-faces of the member 3 include strips of Babbit metal. To reduce wear and friction forces in the rolling of the abutments 4 on the cylindrical surface of the member 3, a thin layer of, e.g., stainless steel, brass or plastics material may be bonded to the outer surfaces of the strips 6, 7 or (10).

Abstract: 632,788. Thermionic distributers. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. June 3, 1946, No. 16765. Convention date, April 10. [Class 40 (iii)] [Also in Group XL (c)] In a multi-channel pulse communication system at least one pulse train is produced the recurrence frequency of which is an integral multiple of the minimum necessary to convey the intelligence and the recurrence frequency is reduced to the minimum by a periodic suppression of pulses. The pulse producing means may form groups, means being provided within each group for the periodic suppression of pulses within a single-channel pulse sequence. In one embodiment providing fifteen interlaced channels, one of which may be a synchronizing channel, a base wave generator 51, Fig. 5, feeds a frequency tripler 52 connected to a delay network 53. The five tappings on network 53 feed phase-displaced waves to group circuits A1 .. A5. Each wave is squared by valve 55, differentiated pulses being derived from the anode inductance 56 and applied to valves 57, 58, 59 in parallel, different channel modulating voltages being applied to their screen grids 60, 61, 62 from transformers 1, 6, 11 respectively. A blocking voltage generator 66 fed with the base wave from generator 51 provides blocking waves to the grids 63, 64, 65, which ensure outputs from the valves 57, 58, 59 only when channels 1, 6 and 11 of the fifteen channel sequence, are to be active. Similarly, group circuit A2 produces pulses corresponding to channels 2, 7 and 12 and so on. At the receiver, a series of pulses similar to those generated by the transmitter are used as gating pulses. Specification 628,408 is referred to.
