Title: Video signal processing apparatus
IPC: H04N9/85
Filed: 1975-09-09
Abstract: 1521503 Colour television RCA CORPORATION 9 Sept 1975 [16 Sept 1974] 37062/75 Heading H4F The invention relates to apparatus for transcoding a video signal of non-standard format where the chrominance information is modulated on a low frequency subcarrier interleaved with a portion of the passband of the luminance signal, for example as is sometimes recorded on capacitative video discs, to a standard, e.g. NTSC type, signal capable of being processed by a conventional receiver. As described the apparatus comprises a modulator 18 for heterodyning the video signal with a reference signal, a one line delay circuit 58 having a limited passband, a notch filter 36 which attenuates about a frequency corresponding to the sum of the chroma subcarrier and heterodyning frequencies, a summation amplifier 48 which produces a signal substantially free of chrominance information since the delayed and non- delayed chroma signals are out of phase, a difference amplifier 70 which produces the chroma signal as a modulated subcarrier at a frequency corresponding to the difference of the frequencies of the heterodyning signal and the original chroma subcarrier, and a summation amplifier 82 for combining the frequency translated chroma and luminance signals. Filter 74 is provided to attenuate about the heterodyning frequency (5À11 MHz as described). Detector 89 samples the luminance at twice subcarrier frequency (10À11 MHz) and has a frequency roll-off of 4 MHz so that a baseband luminance signal is produced for combination with chroma signals produced at the output of filter 80 which has a pass-band of 3-4 MHz for eliminating luminance components. In order to correct for variations in speed of the disc the colour burst signal is separated out by filter 26 and gate 28 controlled by horizontal sync information, and the phase or burst is compared with a reference signal in detector 30 which produces sum and difference signals. The difference signals, passed by filter 34, control the frequency of voltage controlled oscillator 20 so that the difference is removed.

Title: Improvements in methods of and means for knitting fabrics
IPC: D04B3/00
Filed: 1946-12-17
Abstract: 669,813. Knitting. LUND, E. F. Dec. 17, 1946 [July 28, 1945], No. 37110/46. Class 74 (ii). A non-tubular fabric is knitted by means of a series of thread carriers 1, moving stepwise across the fabric, always in the same direction and obliquely to the direction 15 of take-off of the fabric, each carrier conveying its individual thread 3-8 to each in succession, of a series of needles 2 arranged in a straight line parallel to the series of thread carriers, the needles simultaneously knitting stitches, each with the appropriate thread, whereafter the carriers with their individual threads are advanced together one step along the needle line whilst the fabric is moved in the direction of the wales, so that each needle in succession draws, first a loop of the thread offered by the first thread carrier, then, through that loop, a loop of the thread offered by the second thread carrier and so on. The needles are carried on an endless conveyer moved step-by-step in timed relation with the stitch-forming operations of the needles. A casting-off comb 17 is provided. The Specification as open to inspection under Sect. 91 describes circular machine arrangements for plain knitting, rib knitting, or linkslinks knitting, a chain-like thread conveying device, thread tensioning arrangements and a device for cutting lengths of thread suitable for use in the machine producing the non- tubular fabric. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in luminous electric discharge tubes
IPC: H01J61/28
Filed: 1929-12-05
Abstract: 344,072. Metallic - vapour lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. fur Elektrische Gl³hlampen ; 11, Ehrenbergstrasse, Berlin.) Dec. 5, 1929, No. 37307. Convention date, Aug. 6. Addition to 343,053. [Class 39 (i).] In the glowdischarge tube of the parent Specification, the heating of the side tube, for maintaining constant the pressure of the vapour filling, is made dependent on the voltage across or the current intensity through the tube. A tube 1 is connected to the mains through a choke coil 5, and has a side tube 6 surrounded by a. heating winding 8 which is connected to the mains through a resistance 11. The energization of a, solenoid 18 causes a part of the resistance to be short-circuited by an armature 16 through contacts 14, 15. An increase of voltage across the tube. resulting from a reduction in the pressure of the filling, causes an increase in the current in the winding 8 and a subsequent increase in the vapour pressure. In a modification (Fig. 2, not shown), the heating of the side tube is made dependent on the current by connecting the solenoid 18 in series with the tube. In a further modification, an increased heating effect may be obtained by adapting the solenoid to short-circuit a number of turns of the winding 8. Specification 314,925, [Class 39 (i), Electric lamps, Arc &c.], is referred to.
Patent GB-817801-A (GB)
Title: Improvements relating to clothes washers
IPC: D06F23/04
Filed: 1955-11-11
Abstract: 817,801. Washing-machines. GENERAL ELECTRIC CO. Nov. 11, 1955 [Nov. 12, 1954], No. 32352/55. Class 138 (2). In a washing machine comprising an outer tube 14, a rotatable clothes basket 15 having a flared annular side wall, an agitator 22 mounted on a hub 26 within the basket, a pump 49 to circulate liquid from the tub to the basket during the washing operation, such liquid escaping from the basket back to the tub, and means for spinning the basket to dry the clothes, the agitator is provided with a downwardly and outwardly flared skirt 25 which forms with the bottom of the basket an annular cavity which, during the washing operation, constitutes an area of limited turbulence in which relatively heavy insoluble particles extracted from the clothes can accumulate, and the bottom of the basket has a discharge nozzle 59 of inverted conical formation through which the particles are discharged into the tub. The pump 49 is connected by a flexible driving connection 50 to the shaft 51 of a reversible motor 33. The pump may be of the type discharging into one of two outlets depending upon the direction of pump rotation. Alternatively, a pump having a single outlet and appropriate valve means may be used. When the motor 33 is rotating in the direction corresponding to a drive to the agitator 22 the pump 49 discharges through a conduit 53 and nozzle 54 so as to return the liquid to the basket 15. On reverse rotation of the motor 33 for spin drying of clothes in the basket the pump 49 discharges through a waste pipe 55. In a preferred example liquid flows through nozzle 59 at the rate of 1 to 3 gallons per minute, and a flow restrictor 63 in the conduit 53 limits the recirculation flow to e.g. 6 gallons per minute. The excess water overflows through apertures 20 in the basket 15 and maintains 2 to 4 inches of water in the tub 14 during the washing period. This permits heavy soil particles to settle to the bottom of the tub 14 where they remain until all the liquid is pumped from the machine during the extraction stage. A strainer having outwardly extending vanes 62 passes soil particles and the like, but prevents laundry articles passing into the pump 49. A boot 57 extends from the basket hub 26 to the bottom wall of the basket which preferably has a sloping portion 16 and one or more downwardly stepped areas 17, 18. Drive for the agitator and basket is through a bi-directional clutch 34, 35, belts and pulleys, and drive mechanism in a casing 30. Specifications 646,403 and 817,802, [Group XXVI], are referred to.

Abstract: 992,743. I.C. engine cylinders. LAYSTALL ENGINEERING CO. Ltd. Oct. 19, 1962 [Oct. 19, 1961], No. 37516/61. Heading F1B. [Also in Division B3] A method of manufacturing a cylindrical bearing surface comprises the steps of pouring a slurry of an abrasive powder in a liquid vehicle, the powder having been screened accurately to be of predetermined size, into an accurately dimensioned cylinder whilst simultaneously urging particles of the powder into engagement with the cylinder wall on a helical path from one end to the other and back of the cylinder repetitionally. Lubricant-retaining grooves are thus formed, e.g. 0À001-0À003 mm. deep, depending on the size of the particles. The cylinders may be of glass, ceramic or hard steel. An engine cylinder liner is made by deep-drawing it from a blank, removing a bottom blank and top waste, finishing it by grinding, honing or like process to accurate external and internal dimensions, spinning over an end to form an outwardly turned flange, grooving the bore as described above and electro-plating with chromium. The liner may then be subjected to a further grooving process to remove any nodules of chromium deposited in the bore and particularly in the grooves.

[Also in Division G3] Apparatus for controlling the flow of gas to two burners so that the pressure ratio of the gas is maintained constant comprises a valve 2 controlling the flow to a burner 3 and a valve 2A controlling the flow to a burner 3A. Gas is supplied through a pipe 1to the two valves and also through a branch pipe 1B to a manual controller 15 or a temperature controller 14. The controller 14 or 15 provides an adjustable fixed pressure in a conduit 10 which is fed through valve 7 and conduit 10A to load the diaphragm 4 of the valve 2 whereby the outlet pressure of the valve 2 is kept at the value selected by the controller. The outlet from the valve 2 is connected to the burner 3 and also through conduit 6 to provide a loading on the diaphragm 4A of the valve 2. This loading is adjusted by a leak valve 7B to set the lower pressure for the burner 3A. Thus, any variation in the setting of the controller 14 or 15 adjusts the outlet pressure of the valves 2, 2A while maintaining a constant ratio between these pressures. Valves 7A, 7C, 7D are also provided, these valves preferably being connected to a single actuator also common to valves 7 and 7B. whereby the system may be set so that the actuator 14 or 15 sets the pressure of valve 2A and the outlet of this valve sets the pressure of valve 2. A second branch line 1A may be provided which is connected to valves 8, 8A and to a controller 9 which sets a loading on the valves 8, 8A. If the loading pressure for either of valves 2, 2A falls below a value which would provide an undesirable low outlet pressure from these valves, the corresponding valve 8 or 8A opens to maintain the desired loading value. In a modification, the loading pressure of the valves is provided by a fluid separate from the gas supply.
