Title: Remote-control apparatus
IPC: H03G1/02
Filed: 1975-04-11
Abstract: 1486074 Remote control of TV receivers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd (PHILIPS GLOEILAMPENFABRIEKEN NV) 11 April 1975 14978/75 Heading H3Q [Also in Division G4] A plurality N of bidirectionally-variable functions are controlled by repeatedly-transmitted bursts of pulse signals, each burst comprising N + 2 pulses separated by N + 1 intervals each of duration t1 or t2, the first interval of each burst, which has the durations t1 and t2 alternately going from burst to burst, specifying the direction of variation, and each of the other N intervals relating to a respective one of the functions and having the duration t2 of the function is to be varied in the specified direction and t1 otherwise. As disclosed, t2 is twice as long as t1. In the transmitter (Fig. 1), each pulse from a clock pulse generator 11 reverses a bi-stable 10 and triggers the first monostable 13a of a chain of monostables 13a-13g: each monostable triggers the next a duration t1 or t2 after it is itself triggered depending on a duration-selection input at the left (see Fig. 1). The bi-stable 10 provides this input in the case of monostable 13a and selects one of two keys (e.g. 2a, 2b) to provide it in the ease of each other monostable (e.g. 13b). The monostables 13b-13g have duration t2 if the selected key is closed, t1 otherwise. The outputs of the generator 11 and the monostables 13a-13g are differentiated 15a-15h, combined, shaped 17, modulated on to an RF carrier 18, 19 and transmitted by radio. At the receiver (Figs. 3, 7, not shown), after amplification, demodulation and shaping, each pulse drives a 3-bit binary counter (which is reset by a first monostable between bursts), and via a second monostable inhibits a decoder responsive to the counter, the inhibition being effective throughout each interval t1 but only part of each interval t2. The decoder is a 4-bit binary to 1-out-of-16 decoder, the highest order input bit of which is provided from one of its outputs via a third monostable, the effect of which is that the first interval of each burst selects one of two groups of outputs to respond to the other intervals of the burst. The outputs of these two groups each control a function relay via an integrator and Schmitt trigger. Two corresponding outputs (corresponding to keys in the same pair) may also be ANDed to control a relay via an integrator and bi-stable (or Schmitt trigger). The transmitter may include a power supply with a switch which is mechanically coupled to all the keys, or separate. Transmission may be optical or ultrasonic or by cable, instead of by radio. Control of a TV receiver or hi-fi installation is mentioned, it being known to control remotely (in a TV receiver) sound volume, contrast, brightness, channel selection, colour saturation, and switch on and off.

Filed: 1952-06-13
Abstract: 701,488. Photographic contact printing. SCHAAR, H. VAN DER. June 13, 1952, No. 14980/52. Class 98(2) A device in which the original and the photographic material are guided over the surface of a mercury vapour discharge tube or the like or over the surface of a light transmitting cylinder surrounding the tube is characterized in that the guiding means comprise a number of rollers concentrically surrounding the tube or cylinder through more than 180 degrees of its circumference, and urged towards the tube or cylinder which is thus supported by the rollers, so that the original and photographic material can extend beyond the device. As shown, a tubular lamp 1 such as a mercury vapour discharge tube is mounted on supports inside the ends of tube 2. The tube is supported by a number of rollers 4 mounted to rotate freely and to be urged inwardly in a casing 3; e.g. the rollers may have resilient horseshoe-shaped end mountings. A reflector strip 5 is placed between the two uppermost rollers 4, and has turnedover ends overlying the ends of lamp 1, one end having a hole through which the electric leads pass. A roll of photographic paper 11 in a housing 9 is fed round tube 2 under rollers 4 and passes into a casing 13. Casings 9, 13 may be detachably mounted on casing 3. The original 15 is fed between the photographic paper 11 and the tube 2, or if desired may be fed in at 20 between the paper 11 and the rollers 4. To move the paper and original, one of the rollers 4 may be turned by hand, or by a spring motor of adjustable speed. The device may rest on pivoted supports 19 which are turned parallel to the axis of the device when not in use. When a large original is to be copied, it may extend beyond one or both ends of the device; and a strip of the original is copied. A complete copy may be made by sticking several such strips together. A page of a book may be fed into the device, and then rolled back. The tube, too, may be omitted, in which case rollers 4 are in direct contact with the lamp 1.

Title: Camera with exposure regulator
IPC: G03B7/12
Filed: 1959-05-01
Abstract: 888,973. Photo-electric exposure control. AGFA A.G. May 1, 1959 [May 10, 1958], No. 15036/59. Class 40(3). [Also in Group XX] In a camera with a coupled exposure regulator of the type comprising a photo-electric exposure meter with an indicating needle, means for clamping the same in the indication position and a follow-up pointer, coupled to exposure value setting means, arranged to contact the needle, in which regulator a driving member for the follow-up pointer is connected on one hand" with the coupled exposure value setting means and on the other hand by way of an overload coupling with said pointer so that on arrest of the pointer by the clamped exposure meter needle the said driving member continues its angular movement, the construction is such that during this continued movement the driving member also becomes axially displaced with reference to the pointer and meets arresting means so arranged that its position when arrested is in predetermined angular relation to the position of the needle. As shown, a follow-up pointer 8 is pivotally mounted about a pin 11 by means of a bushing 10. A driving member 13 for said follow-up pointer is screw-threadedly mounted on the bushing 10 and is coupled thereto by way of an overload coupling comprising a spring 16 connected to the members 10 and 13 and urging abutments thereof together. On depression of a body release 29 for exposure, by way of a rods 31 coupled to said release 29 through a spring 39, a spring-urged clamping plate 6 for clamping the exposure meter needle 3 is released and an arm 9 of the driving member '13 is rotated. On engagement of the clamped pointer 3 by the follow-up pointer 3, the overload coupling is broken and the driving member 13 continues to rotate on the threading of member 10 against the loading of spring 16 until an abutment surface 19 of the member 13 engages with a fixed arresting surface 12. The exposure value setting means (not shown in detail) is thereby set according to prevailing light conditions by way of the coupling 37, 38. Release of the shutter is effected when projection 32 on release 29 engages with release rod 33. A return spring 40 is provided. The galvanometer 2 may be rotatably coupled to a knurled ring 25, 26 for setting in terms of film sensitivity.

Title: Apparatus for projecting sub-titles to accompany projected motion-picture films
IPC: G03B21/26
Filed: 1954-05-21
Abstract: 753,926. Kinematograph apparatus. LEPELLEY, L. May 21, 1954 [June 2, 1953; Oct. 1, 1953; March 31, 1954No. 15059/54. Drawings to Specification. Class 97 (1). Sub-titles are projected from an independent film fed intermittently, as required, in an auxiliary projector under the control of signals from the main film, an area of the main image being masked to accommodate the sub-title. When a feeler, for example, engages a hole or notch provided in the main film contacts are allowed to close and, preferably through a relay, energize a solenoid to rotate a sprocket through a ratchet and feed the sub-title film. Separate sub-titles are separated by blank frames. Alternatively, a shutter may cover the light beam of the auxiliary projector when no sub-title is required. Another electromagnet is energized, when a sub-title is projected, to move a small shutter into the path of the light beam of the main projector to blank out the area of the main image where the sub-title is to appear. In alternative arrangements the control signals are derived from the main film photo-electrically or from a magnetic track on the film.

Title: Process of producing coke from carbonaceous fuels
IPC: C10B13/00
Filed: 1930-05-16
Abstract: 353,139. Coking processes. HILGER, G., 1A, Marienstrasse, Gleiwitz, Germany. May 16, 1930, No. 15088. [Classes 55 (i) and 55 (ii).] Hard coke is obtained from coal, lignite, peat, or wood, by mixing with the charge fuel dust, and stirring or shaking it so that the interstices between the pieces of fuel are filled up, and subjecting the charge to pressure, gas outlet channels being formed in the compressed charge by inserting and withdrawing spikes or tubes. These channels may be filled with non- fusible substances such as coke to keep them open. Waste pitch may be added to the filling material. Tubes filled with non-fusible substances may be put into the coking chamber and withdrawn, leaving the filling behind. Passages may also be made by introducing ropes of straw, reeds or wood wool, or wooden rods, more easily carbonizable than the coal charge. Weights may be placed on the charge entirely covering its upper surface and having perforations to allow of escape of distillates, and a hydraulic press may be used to increase the pressure. The loading weight may take the form of a gas withdrawal hood. The charge may be compressed into perforated iron receptacles. Gas suction tubes may be inserted to prevent the distillates from coming into contact with the hot retort walls, and an internal heating element may be provided. The compression may be effected so that it decreases towards the centre of the charge, and may be exerted by falling weights or rammers so that the pressing may be made layer by layer. Lateral compression may be made by stirring rods, or wedges. The charge may be contained in a perforated casing 1, having at its bottom an extension frame 1a into which the casing falls during contraction of the charge. A perforated gas outlet pipe 1b assists the escape of distillates which pass through a tube 14 to a collecting pipe 24. A weight 13 is mounted on the tube 14, and is raised or lowered by a hand-wheel 18 so as to compress the charge. In Fig. 4 a stamper 9 having holes 10 to allow the freshly charged material to pass is used to compress the charge around spikes 3 which are subsequently withdrawn to leave gas outlet channels. Fig. 6 shows vertical tubes 11 around which the charge is compressed to leave vertical outlet passages when the tubes are withdrawn.

Title: Improvements in or relating to gas-filled electric discharge devices
Inventor: BUCKINGHAM JOHN DOBLE
IPC: H01J61/28
Filed: 1955-05-26
Abstract: 806,946. Discharge tubes. GENERAL ELECTRIC CO. Ltd. May 28, 1956 [May 26, 1955], No. 15292/55. Class 39(1). A gas filled electric discharge device, preferably a hydrogen filled lamp for D.C. operation, has a gas reservoir in the form of a container 14 of electrically resistive material substantially filled with a substance (Ti in the case of a hydrogen filling) which evolves gas on heating and reabsorbs it on cooling, the container 14 having apertures of such size that the substance cannot escape but gas can pass freely in or out, the container 14 having leads 18, 19 for passage of heating current through the material of the container along the walls of the container so as to heat the container, the arrangements being such that when the container is unheated the gas pressure is small compared with the desired operating pressure. In the form shown the gas reservoir contained inside tube 13 comprises four similar tubes 14 of 28 per cent. Ni, 18 per cent. Co and 54 per cent. Fe having helically arranged apertures and having Ti chips therewithin. The tubes 14 are connected by three lengths 15 of nickel wire which are inserted in and seal the ends of the tubes 14 to which they are spot welded, the current leads 18, 19 being similarly secured to the free ends of tubes 14. Two annular ceramic spacers 16, 17 strengthen the assembly and bent nickel spring strips 20 keep it centrally in the side tube. After assembly and processing but before sealing off the hydrogen is introduced and absorbed in the titanium until there are 60 ccs hydrogen at normal temperature and pressure contained in the titanium. The heating current through 18, 14, 19 is 8 amps. at 4 volts which heats 14 to 550‹C., and an operating equilibrium pressure of 5 mm. Hg is reached in 45 seconds from the time of application of the heating current. For no heating current substantially all the hydrogen is reabsorbed by the titanium, the residual hydrogen pressure being less than 0À005 mm. Hg. The cathode 1 is a helix of W-Mo alloy and is surrounded by a nickel cylinder 2 closed at each end followed by a semicylindrical nickel anode 3. The anode 3 is supported at one end from cylinder 2 by an insulating glass bead 9 and at the other end by current lead 10. Electrodes 2, 3 have slits for light to emerge through quartz window 5 which is cemented by wax to side tube 6. The cemented wax seal is cooled by water circulation through tubes 7, 8. The invention can also be applied to other forms of gas filled electric discharge device including devices with mixtures of gases in which case the resevoir keeps the pressure of one gas constant. Specification 806,945 is referred to.
