Title: Light valve projector
IPC: H04N5/82
Filed: 1964-10-12
Abstract: 1,081,445. Light modulating. GENERAL ELECTRIC CO. Oct. 12, 1964 [Oct. 18, 1963], No. 41604/64. Heading H4F. [Also in Division H1] In a light valve projector in which a thermoplastic tape 15 is deformed by a scanning electron beam modulated by a video signal, the tape is heated by heater 35 so that the viscosity of the tape is uniform over the whole of the scanned raster area 27 i.e. the region of the tape which has been subjected to electron bombardment for a longer period is heated more than the rest of the tape since electron bombardment increases the viscosity of the thermoplastic. The tape 15 is arranged to slowly pass from reel 22 to reel 28 which are contained in housing 28 which is attached to the beam focusing and deflection section 13 and beam generating section 12 i.e. the tape is renewed at the rate determined by the useful life of the material. The tape is heated on the side facing the electron beam by means of a resistancetype heater element 35 which surrounds the raster area, Fig. 2 (not shown), and has additional turns at the exit end of the raster area 27 so that there is a temperature gradient. The amount of heat supplied to the tape may be adjusted by varying the distance between the tape surface and heater element. The tape comprises a layer of deformable thermoplastic on a transparent conducting layer which is supported on a base layer. The electron gun 43 is secured to the assembly through a glass disc 44, an array of cylindrical lenticular lens elements 45 and a slot mask 46, Fig. 3 (not shown). The frequency of the oscillating voltage on which the video signal is amplitude modulated, which is applied to horizontal deflecting electrodes 50, 51, determines the grating spacing of the deformations formed on the tape 15. The light system for projecting a picture comprises in addition to lenses 45 and mask 46 a lamp 62 mounted within an ellipsoidal mirror 63 and a plurality of cylindrical lenticulas lenses 64 which image the light source in the slots of mask 46. The lenses 45 image the source lenses 64 on the raster area of the tape with each image occupying the full raster area. The output optics include a Schlieren lens 66, a projection lens 67 and an output mask 68 similar to mask 46 but optically displaced so as to stop the light in the absence of deformations in tape 15.

Abstract: 1,162,116. Machinery guards. WILMOT BREEDEN Ltd. 18 Sept., 1967 [19 Sept., 1966], No. 41667/66. Heading F2J. In a riveting machine, a guard device comprises U-shaped members 23, 24 secured to pivotally mounted arms 12, 13 which are moved from the guarding position to an inoperative position by a power operable device 20, against the action of a spring 17, and control means associated with the power operable device 20 which permit operation of the machine only when the U-shaped members 23, 24 occupy their guarding position. Arm 13 is mounted on a pivot 15 at one end and arm 12 is mounted on a pivot 14 intermediate its ends, the arms 12, 13 being interconnected by a link 16. An adjustable abutment 18 on the end of arm 12 engages the stem 19 of a piston and cylinder unit constituting the power operable device 20. A pneumatic valve is incorporated in the device 20 and controls the supply of air to the ram of the riveting machine. A foot-operated valve controls the guard and machine, and normally allows compressed air to be supplied to the unit 20. When this valve is operated, the unit 20 is exhausted thereby allowing spring 17 to close the guard members and effect actuation of the valve incorporated in the device 20 to permit the supply of air to the ram of the machine.

Title: Frequency-shift keying discriminator

Filed: 1974-09-25
Abstract: 1482693 Data transmission; FSK systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Sept 1974 [28 Sept 1973] 41697/74 Headings H4P and H3A A FSK receiver discriminator has a number of parallel channels each receiving a common fixed frequency higher than that of the FSK signals, and giving an output through a phase comparator to a low pass filter providing recovered data. Each channel has a phase adjusting circuit controlled by pulses from a detector operable by zero crossings. Each phase adjusting circuit may be constituted by a dividing circuit with all stages resettable simultaneously from the zero crossing pulses. The arrangement is stated to be sensitive to a narrow modulation frequency difference. Incoming signals are passed through a band pass filter 2 to a discriminator 3 having a number of channels C1, C2 fed from a common generator 7, outputs being connected to a phase comparator 8 and low pass filter 10. In one embodiment, D1, D2 are counters and phase adjusting circuits R1, R2 are reset circuits to which pulses are applied from signals derived from a zero crossing detector, comprising a slicer 11, bi-stable trigger 12 connected as a 2 : 1 divider and difference network 13 whose positive and negative outputs are passed through oppositely poled diodes 14, 15. Phase comparator 8 is constituted by a NAND gate output passing through a low pass filter 10 and D.C. restorer 4 to a pulse regenerator 5. By alternately resetting counters D1, D2 dependent upon positive and negative transitions, the relative phase of the output is a measure of input frequency which determines the time between successive resets. In another arrangement (Fig. 6, not shown) the counters are replaced by three registers having a gated feed-back, compared cyclically in pairs with the third merely supplying an enabling signal. Slicer (11) output clocks a 3 : 1 divider formed by register stages (17, 18) feeding into NAND (19). This arrangement causes one of the registers (SR1-SR3) to give a 1 output blocking one channel in a cyclic sequence hence comparator 8 monitors the relativities of signals coming from the other two. The Fig. 6 arrangement is stated to be particularly suitable for MOST techniques.
