Title: Colour television apparatus
IPC: H04N9/76
Filed: 1970-08-24
Abstract: 1318733 Colour television ROBERT BOSCH FERNSEHANLAGEN GmbH 24 Aug 1970 [23 Aug 1969] 40702/70 Heading H4F When the instantaneous amplitude of a video signal 1 derived by scanning a character in a diapositive scanner 1 is sufficient to actuate trigger circuits 5, 6, the passage of a normal PAL signal 2 to an adder 24 is interrupted by a gate 8 and a gate 9 opens to pass to the adder 24 a synthesized PAL type signal which is manually adjustable as to hue, saturation and luminance, so that the signal 25 provides a picture wherein the character is substitutionally inserted in the normal picture given by signal 2. A potentiometer 26 enables signals 25 and 2 to be mixed for fading the character in and out of the picture. A reference subcarrier 11 derived from signal 2 is fed via a transformer 13 to potential dividers 14 and 15 associated with coupled rotary switches 16 and 17 respectively, the arrangement being such that the outputs of the switches have amplitudes represented by A sin # and A cos #. The output of one switch then undergoes phase changes of + 90 degrees and - 90 degrees in alternate lines in a circuit 19 controlled by sync. and PAL switching signals of signal 2 before being added to the output of the other switch to form a PAL type subcarrier adjustable in phase (hue) according to the setting of switches 16, 17. The amplitude (saturation) of the carrier is adjusted by a potentiometer 10 before it is added to a luminance signal, which is derived from the output of trigger 5 via a rotary switch 22 and voltage dividers 23 for varying the amplitude thereof. As described, switch 22 is coupled to switches 16, 17. The threshold voltage of trigger 5 is at least as great, and preferably greater than, that of trigger 6, so that the inserted character is clearly delineated.

Abstract: 1,115,958. Rotary thermal regenerators. AUSTIN MOTOR CO. Ltd. 19 Sept., 1966 [6 Oct., 1965], No. 42505/65. Heading F4K. A regenerative heat-exchanger comprises a rotary cylindrical matrix of non-metallic refractory material, the periphery of the matrix being engaged frictionally by a flexible belt 5 that is driven by a pulley 6, and is made of heat resistant material that is wholly or predominantly non-metallic. In the form shown, the rotary matrix consists of an annular foraminated ceramic core 1 held between ceramic rings 2 and 3, and mounted on a centre shaft 4. Since the driving pulley 6 has a small diameter and is situated close to the ring 3, sufficient circumferential engagement of the pulley 6 by the driving belt 5 is ensured by the use of two jockey pulleys 7, 8 disposed in juxtaposition to the pulley 6 at opposite sides, and adjacent to, the plane containing the rotational axes of the driving pulley and the matrix. A tension spring 9 ensures that the driving belt is maintained taut. The periphery of the ring 3 is grooved to receive the driving belt 5 of which various cross-sections are depicted in Figs. 2 to 5 (not shown). The matrix has a central journal bearing consisting of a spherical bush (10) held in a spherical mounting (11) (Fig. 6) designed to permit slight tilting. of the matrix due to possible differential expansion and limited axial movement of the spherical bush, so that slight axial movement of the matrix is possible to take up wear of its seals (13, 14).

Abstract: 980,084. Closure seating means. VAN LEER INDUSTRIES Ltd. Nov. 13, 1962 [Nov. 29, 1961; Jan. 10, 1962], Nos. 42648/61 and 914/62. Heading B8T. A closure seating means for a sheet-metal container comprises a plurality of tongues 16 integral with and, substantially perpendicular to the container wall 11 and positioned in annular configuration, having portions of screwthreads forming part of a substantially common helix pressed therein. A plug may be screwed into the seating means or a threaded cap may be screwed on to it. To produce the seating means a central hole 13, Fig. 4, and slots 12 are diestamped from the wall of a container and alternating grooves 14 and ridges 15 are pressed in the resulting tongues 16 to form a helix and finally the tongues 16 are bent out of the plane of the container wall to project substantially at right-angles. With reference to Fig. 7, a sleeve 20, with teeth 23 which partly protrude into the slots 12, is inserted into the closure seating means, with a sealing gasket 21 interposed between the sleeve and a marginal wall 17. A second gasket 24 is provided before a plug 19 is introduced into the seating means; after the plug has been screwed home a sealing cap 25 is placed on the top of the plug and is rolled around the edge 22 of the sleeve 20 to provide a tamper-proof and pilfer-proof seal. In another embodiment the sleeve 20 is formed of a resilient plastics material and has an enlarged shoulder which may enable the gasket 21 to be dispensed with. The sleeve may also be provided with holes in the edge 22 to receive sealing wires threaded through corresponding holes in the plug, thus affording the possibility of dispensing with the seal cap 25.

Filed: 1962-11-12
Abstract: 1,023,666. Etching PN Junctions. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 12, 1962 [Nov. 15, 1961], No. 42656/62. Heading H1K. The area of a PN junction is reduced by etching chemically in a non-conducting solution which has no etching action at room temperature. A current is passed through the junction to heat it to a temperature at which the etchant is effective. A tunnel diode formed by gold soldering a P-type germanium wafer to a support plate and alloying tin-germaniumarsenic alloy to its other face may be so treated. Preferably it is first electrolytically etched in caustic potash. During etching, in which the etching current is progressively reduced, the diode V-I characteristic is measured periodically. After rinsing in water a drop 10 (Fig. 3) of dilute hydrogen peroxide is placed around the PN junction and a heating current passed through the junction. The characteristic is again displayed and the heating current reduced as the desired characteristic is approached. Other suitable etchants are solutions of a halogen, e.g. iodine, in a wateralcohol mixture. The method is equally applicable to conventional diodes and transistors and transistors with tunnel junction emitters.

Abstract: 1,076,116. Automatic control of aircraft. BODENSEEWERK PERKIN-ELMER & CO. G. m. b. H. Oct. 23, 1964 [Oct. 26, 1963], No.43360/64. Heading G3R. In an aircraft automatic pilot, an integrating, restrained gyro controlling roll stabilization is torqued about its precession axis by differentiated signals from a turn controller and by signals from an apparent vertical detector. As shown, gyros 1, 1' respectively responsive to roll and yaw of an aircraft are restrained about their precession axes by pneumatic cylinders 2, 2' having throttled outlets so that bridge-connected pick-offs 3, 3' produce electrical outputs, each dependent on both deflection and integral of deflection about the roll and yaw axes, to respectively control servoactuated ailerons and rudder (not shown) and thus maintain the aircraft in a desired altitude. A similar gyro may also stabilize the aircraft about its pitch axis. Turns may be produced by a manual controller 7, signals from the electrical pick-off 6 of which are applied through an amplifier 5' to torque the yaw gyro. A pendulum QU develops an electrical signal, corresponding to the error between the true and apparent vertical during turn, which is applied through an amplifier 5 to torque the roll gyro so that the aircraft is banked to produce a properly co-ordinated turn. To reduce the initial signal from the pendulum, the signal from manual controller 7 is differentiated by a transformer 10 and applied through amplifier 5 to torque the yaw gyro. The signal thus applied is limited by saturation of transformer 10 and is varied in dependence on aircraft velocity by causing the latter to vary a potentiometer 9. In the case of radar or localizer radio control the appropriate receiver output may be substituted for that of pickoff 6.

Filed: 1969-09-02
Abstract: 1,218,919. Epoxyalkyl ester resins. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 2 Sept., 1969, No. 43397/69. Heading C3B. Branched chain epoxyalkyl ester resins containing alcoholic OH groups are derived from acids containing at least two COOH groups and a cycloaliphatic ring of at least five carbon atoms. When two COOH groups are directly attached to the same ring they are separated by not more than 3 ring carbon atoms. The ratio of the average number of epoxy groups per molecule of the resin to the number of COOH groups in the acid is at least 1À1:1. A preferred acid is hexahydrophthalic acid. The resins can be prepared by reacting an alkali metal salt of the carboxylic acid with an epoxymonohaloalkane having the halogen atom adjacent to the epoxy group (e.g. epichlorohydrin) under conditions such that: (1) the ratio of converted plus non-converted epoxyhaloalkane to converted plus non-converted salt corresponds to at most 1À5 gram moles of epoxyhaloalkane per gram atom of alkali metal; (ii) the temperature is >50‹ C.; and (iii) the water content of the reaction mixture is <0À3% by wt. The resultant product is contacted with water which converts alkali metal alcoholate groups in the resin to free hydroxyl groups. The amounts of water and epoxyhaloalkane may initially be outside the limits prescribed above, excess being removed by distillation, e.g. with a water entrainer such as toluene. A catalyst, e.g. a quaternary ammonium salt, may be employed. The resins may be cross-linked by conventional epoxy resin hardeners, e.g. hexahydrophthalic acid catalysed by dimethylbenzylamine.
