Title: Receiver for a combined sound and television waveform
IPC: H03D3/04
Filed: 1945-07-14
Abstract: 602,032. Pulse modulation diplex pulse signalling. LAWSON, D. I., and PYE, Ltd. July 14, 1945, No. 18055. [Class 40 (v)] Phase or frequency-modulated sound pulses occurring within the line synchronizing periods in a combined sound and television wave-form are converted to amplitude modulated pulses by mixing with auxiliary pulses of saw-tooth wave-form generated by means triggered by the line synchronizing pulses. The combined wave-form is applied to valve V1, and a train of saw-tooth pulses to the grid of valve V2. The saw-tooth pulses occur at a repetition frequency corresponding to the line synchronizing pulse frequency and are of a duration not exceeding the time synchronizing period, being timed to occur during this period. The two wave-forms are mixed in the common anode circuit R of valves V1, V2, where the sound pulses are now amplitude modulated and, at the same time, raised above the level of the picture signals. A clipper diode V3 isolates the sound pulses and the modulation is recovered by passage through a low-pass filter F. Specifications 581,811 and 602,033 are referred to. Reference has been directed by the Comptroller to Specification 579,565.

Abstract: 124,394. Naillik Motor Signal Co., and Ogden, J. P. Nov. 5, 1918. Road traffic signals on vehicles; lamp signals; semaphore signals. - Signals indicating intended turning to the right or left of a motor road vehicle are operated electrically from contacts on the clutch and brake levers. Signals are mounted on each side of the vehicle and comprise a hand 50, Fig. 7, mounted on the armature 54 of a motor arranged to raise the hand to a horizontal position. The field windings 55, 56, and the armature winding 60 are in series, and are in parallel with the lamp 10. The clutch lever carries two contacts, either of which may be closed without operating the lever, to indicate turning to the right or left. When the clutch lever is operated, both contacts are closed, and both signals are raised and illuminated to indicate stopping. A contact on the brake lever also completes the circuits of both signals. Fig. 8 shows one of the contacts on the clutch lever. When the button 24 is depressed, the spindle 20 completes the contacts 21, 22. The reduced portion 85 of the spindle extends through the sleeve 86 and has a lead 87 against which the spring 88 bears. When pressure is released from the button 24, the spring 84 returns the button and subsequently the spring 88 returns the spindle 20. The levers may be operated by hand or by foot.

Abstract: 894,585. Valve amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 6, 1958 [June 8, 1957], No. 18145/58. Class 40(6). In an I.F. amplifier for television signals of the vestigial sideband type, the earlier stages BF1, 2, 3 are tuned to obtain the desired amplitude/frequency characteristic (Fig. 1, not shown) and the resulting phase distortion is corrected in the last tuned stage CN. The circuits BF1, 2, 3 are adjusted to give a flat response for the transmitted sideband and an attenuation to a half at the I.F. carrier frequency, whereas the circuit CN coupling the last I.F. amplifier to the detector 5 is adjusted to have a response which is symmetrical about the I.F. carrier frequency and flat over a frequency range wide enough to embrace the whole of the transmitted sideband. An additional circuit (not shown) may be included in the filter CN to give increased attenuation of the sound carrier.

Title: Improved game apparatus
IPC: A63F9/14
Filed: 1947-07-09
Abstract: 644,323. Race games. TAYLOR, H. E. C. July 9, 1947, No. 18146. [Class 132 (ii)] Race game apparatus comprises tracks t 1 , t 2  along which models x, y can run and means operable by the players at one or more points a on the tracks to accelerate by mechanical or gravitational action the models together with automatically actuated accelerating means at other points b. Each player controls one track by a wheel 3 coupled by a chain 5 to a shaft 6 linked by a bar 9 to a shaft 10, the shafts 6, 10 carrying cams 7, 7<SP>1</SP>, 11 which support a plate beneath the tracks. Extending vertically from this plate are rods 16, one for each position a, which carry fingers 17 each engaging a bell-crank lever 19 acted on by a spring 21. The models x, y each have a depending part 23, 24 carrying a pivoted abutment 22. When the wheel 3 is rotated clockwise the rods 16 are raised by the cams 7, 71, 11 to move the lever 19 to the left (Fig. 3). If a model is passing above a section a at this moment the lever 19 urged by the spring 21 will engage the part 22 to accelerate the model. Similar mechanism operated by the wheel 4 is provided for the other player. Automatically actuated means are provided to ensure that a model will complete the circuit even though not engaged by the levers 19. A plate 38, supported beneath the tracks on cams 50 rotated by a shaft 45 and ratchet drive 43, 44 at the start of each race, carries vertical rods 37, two at each position b. The rods 37 when raised move levers 33, 36 to the left, Fig. 6, the lever 36 in its motion knocking a retaining catch 40 to hold lever 33 to the left. When a model comes to a point b a stop 23a engages the lever 36 which hits the catch 40 to release the lever 33 which then propels the model forward. The apparatus may be coin freed. Each player may brake his opponent's control by anti-clockwise rotation of his wheel 3 or 4. The above accelerating means may be replaced by pivoted sections of the track which on being tilted form ramps to accelerate the models, and in this construction the models may be in the form of balls or rollers. Alternatively flexible sections of the track may be raised to form humps down which the models may run. The progress and result of the game may be indicated by coloured lights. The Provisional Specification describes a modification similar to that described in Specification 658,086.

Abstract: 653,698. Multicolour decoration. CALICO PRINTERS' ASSOCIATION, Ltd., ISHERWOOD, F., and MILLER, W. S. July 14, 1948, No. 18894. [Class 98 (ii)] Sheet material such as textile fabrics or paper is provided with a multicolour design with avoidance of registration difficulties caused by dimensional changes of the material in washing it between production of the several colours, by sensitizing the material with a composition to produce a dye on light-exposure, exposing to light in selected areas as by use of a stencil, and treating with a desensitizer, the cycle of operations being repeated for each further colour required, the material being fixed as regards dimensions as in a frame by means of pins, or by use of frictional forces, pressure, suction, adhesive, by stiffening the material or by use of a stentor, on or after application of the first sensitizer, without washing the material before the last exposure. Sensitizers may comprise sulphuric esters of leuco vat dyes, diazo compounds used with coupling components, or in the case of the last of the cycles, alkali chromates by use of which a dye can be fixed to the material after it is washed; and may be applied as by spraying or brushing in aqueous or aqueous-solvent solution which may contain hygroscopic agents or catalysts for fixing colours. Usually the desensitizer consists of, or is incorporated with, the sensitizer applied for the next colour. In example (1) cotton cambric is padded with aqueous sodium salt of 4.4<SP>1</SP>-dimethyl-6.6<SP>1</SP>-dichloro-thioindigo, stretched on a frame and fixed with pins, dried, exposed through a red separation negative, sprayed with an aqueous alkaline solution containing 2- sodium diazo-sulpho-4-chloro-toluene and diaceto-acetic-o-tolidide which serves as red desensitizer and yellow sensitizer, exposed through the yellow printer, sprayed with aqueous sodium chromate, hydroxide, thiosulphate and sulphite, dried, exposed through the blue printer, removed from the frame, rinsed, soaped, boiled, dyed with chromazurine G and again soaped and rinsed, to show a colour picture. In example 2 a viscose taffeta cloth is treated by a similar series of operations with the sodium salt of the disulphuric ester of leuco 5.7-51.71-tetrabromo-indigo containing copper acetate as catalyst for the blue colour, alkaline 2-hydroxy-3-naphthoic-2.4-dimethoxy- 5-chloranilide and 2-sodium diazo-sulpho-6- chlorotoluene for red, and chromate treatment with dyeing by Persian Berry extract for yellow. Three further examples specify similar colour-producing cycles.
