Abstract: 1,021,286. Sewing machines. LOUIS HAND Inc. Aug. 17, 1964, No. 33496/64. Heading DIG. A sewing machine comprises an electricallyheated thread-cutting member which is located forwardly of the sewing needle, is movable between positions respectively above and below the horizontally-extending path of work feed and is normally biased to its upper position, suction means located adjacent said path and cutting member, and means actuated by the advance of a work piece past a predetermined point for urging the cutting member to its lower position and for releasing the cutting member for return to its upper position upon passage of the work piece past said predetermined point. An L-shaped throat plate 12 is flush with the work-supporting plate 13 and is secured to a plate 22 which is secured to the undersurface of plate 13. An aperture 16 is defined by one edge 14 of the throat plate and the adjacent edge of plate 13. The presser foot 18 has secured to one edge an arm 20 which is flush with the undersurface of the presser foot and which is disposed above the aperture 16. An arm 30 is pivoted to a flange 26 on plate 22 and comprises an upper conducting bar 32 separated by insulation 34 from a lower conducting bar 33. Bars 32, 33 are connected together at one end by a U-shaped resistance element 40 disposed in the line of stitching but normally positioned above the work-supporting surface. A member 49, pivoted at 48 to a flange or plate 22, is disposed in aperture 16 between edge 14 and arm 20, and, has a forked end 50 which embraces arm 30. When the leading edge of a work piece is fed beneath the presser foot 18 by the dogs 17 to engage the member 49, the latter is pivoted to depress the heated element 40 below the work-supporting surface. When the trailing end of the work piece releases member 49, element 40 rises to sever the thread chain adjacent said trailing end. The continuing thread chain then passes into a suction duct 51 and is severed adjacent the leading edge of the succeeding work piece when the latter engages member 49.

Filed: 1956-11-02
Abstract: 820,181. Cathode ray tubes. GENERAL ELECTRIC CO. Ltd. Nov. 4, 1957 [Nov. 2, 1956], No. 33569/56. Class 39(1). At the junction of the neck and flared portions of a cathode ray tube, preferably a television receiver, the envelope is formed with four indentations 6, Figs. 1, 2, in its inner surface, the indentations being located at the corners of a rectangle so that larger extreme scanning angles can be used without cutting off the corners of the rectangular picture ; since the outside surface of the neck at the junction is smoothly cylindrical (as is the remainder of the neck) no modification of the scan coils is necessary as would be required if as in a prior art proposal the inner and outer surfaces at the junction of neck and flared portion were both rectangular. The flared portion is preferably formed by pressing in a mould the four indentations 6 preferably being formed during the pressing operation. The envelope portion produced by the pressing operation has a projecting cylindrical part with a closed end, most of which is cut off to leave a small stub 4 which is sealed to neck 5. The face plate 2 which is preferably dished and preferably carries the luminescent layer (or the luminescent layer may be on a separate support) is sealed to the flared portion 1. The rectangle at the corners of which the indentations are located may have sides in the ratio of 4 : 3. The flared part of the envelope can be of circular or rectangular cross-section (in the latter case it is of circular cross-section at the junction with the necks). Other prior art cathode ray tubes are referred to such as those in which at the junction point the neck has a thinner wall or a greater diameter than the remainder of the neck.

Filed: 1958-10-21
Abstract: 883,956. Electromagnetic relays. BERNSTEIN, A. C., KARR, N. A., and SEAMAN, P. H. Oct. 21, 1958, No. 33643/58. Class 38 (5). A relay generally similar to that disclosed in Specification 749,316 has the permanent magnet mounted to form a third magnetic circuit not subject to demagnetizing flux on energization of the relay coil. The first magnetic circuit comprises a U-shaped core 1 and the righthand part of the armature 3 and the second circuit comprises a U-shaped core 2 and the left-hand part of the armature. The inner limb of the core 1 is spaced further from the armature than the other core links so that the flux from a cross-magnetized permanent magnet 23 follows the path shown by fall arrows and biases the armature as shown. When the coil 6, surrounding the inner core limbs and permanent magnet, is energized by D.C. flux flows in the cores 1, 2 in the directions shown by the dotted arrows opposing the permanent magnet flux in the core 1 and moving the armature to engage the end of the core 2. Alternatively (Fig. 4), the magnet 23 may be replaced by a non-magnetic spacer 24 with a permanent magnet 25 across the base of the cores. The armature, which is preferably dynamically balanced may be pivoted at 4 on the core 2 (as shown) or on separate posts. The bridging moving contacts and the printed circuit fixed contact arrangement are similar to that described in the above Specification and may be offset if the pivotal axis is not at the geometric axis of the armature.

Title: Improvements in or relating to transistor pulse discriminator circuit arrangements
IPC: H04N5/10
Filed: 1957-10-31
Abstract: 870,613. Transistor pulse discriminating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 31, 1957 [Nov. 3, 1956], No, 34029/57. Class 40(6) In a circuit responsive to the ratio of pulse widths to periodicity, the input pulses are applied to the base of transistor 1, biased to be normally non-conducting and arranged with an inductor 6 in the emitter lead which with the impedance of the emitter-collector path forms an integrating network so that the pulses occurring in the emitter-collector circuit, after a given number, are of insufficient amplitude to operate a biased amplifier 13. In the absence of an input, transistor 10 conducts to maintain its collector and the base of transistor 1 at a potential Vbo, more positive than the bias Veo, set up by the potential divider 4, 5 with the result that transistor 1 is held cut off. Transistor 13 is also biased off by resistors 14, 15. An input pulse, applied at t 1 , cuts off transistor 10, the collector potential falling so that transistor 1 commences to conduct with base current determined by resistor 9. A potential nearly equal to VeoV 2  appears across inductor 6 and the emitter current increases during the pulse, the potential Ve<SP>1</SP> at the join of resistors 4, 5 falling until the end of the imput pulse. The back e.m.f. in inductor 6 maintains the transistor 1 conducting with decreasing emitter current until, at t 2 , the next pulse causes the emitter current to increase again. Since only the first pulse occurring across winding 6 exceeds the threshold A, only this pulse is passed to the output. If shorter pulses are employed, all are passed to the output, Fig. 3 (lower curve, not shown). The secondary winding 8 may be replaced by a differentiating resistor-capacitor connection, and a further inductor 3 may be included in the collector circuit of transistor 1.

Abstract: 1,059,502. Condenser systems for steam. C. A. PARSONS & CO. Ltd. Aug. 8, 1963 [Sept. 7, 1962], No. 34413/62. Heading BIB. In a condenser system in which steam from turbine 1 flows into condenser 2 where the steam is brought into direct contact with cooling water introduced through spray 3, and part of the warm water leaving the condenser is pumped through the tubes of a heat-exchanger 5 where the water is cooled by air flowing over the outside of the tubes, the cooled water being then re-circulated to the condenser 2, the minimum pressure of the water in the circulating system is maintained at least equal to atmospheric pressure by a standpipe which is open to the atmosphere and is provided with a float arm connected to a flow-control valve 10. The standpipe may be located at the highest point 7 in the system, and in this case the float arm 9, which varies the opening of valve 10, prevents an excessive pressure in the circulating system and also prevents the overflow of water from the standpipe. If the standpipe is located at position 8, it may take the form of a mercury column supported by the water in the system. In this case the float arm 9 varies the opening of valve 10 to maintain the minimum level of liquid in the standpipe to ensure that the pressure at the highest point in the system shell be at least equal to atmospheric pressure. In systems where a water turbine 11 is used to recover power from the potential energy of the water, the liquid-level device may operate the variable inlet guide vanes of the turbine.

Abstract: The products obtained by passing a mixture of mineral oil vapour and air through a catalytic material under regulated temperature conditions as described in Specification 138,113, [Class 2 (iii), Dyes &c.], are worked up to produce lubricants and soaps.  As starting materials for the partial combustion process, a crude petroleum, gas oil, or shale oil is employed, or the products resulting from cracking a heavy oil or distillate at atmospheric pressure.  The condensed reaction products contain aldehyde fatty acids, aldehydes, alcohols, light hydrocarbons, and waxes.  The products may first be distilled to give a motor spirit, and the remainder then treated with a hydroxide of an alkali or alkaline earth metal to remove the aldehyde acids.  The alkali salts have the usual properties of soaps.  The residue, consisting of alcohols, aldehydes and waxes, is suitable for use as a lubricant.  It may be thickened or resinified before, during, or after removal of the aldehyde acids by treatment with dry hydrochloric acid, anhydrous calcium or zinc chloride, or phosphoric acids.  The resinified products are acidic in character, and may also be converted into lime and soda soaps. Specification 174,099 also is referred to.

Title: Improvements in and relating to methods of manufacturing gas discharge lamps
IPC: H01J9/24
Filed: 1963-09-02
Abstract: A method of manufacturing gas discharge lamps wherein a glass tube which is provided at both ends with an opening through which the interior of the tube communicates with the space outside the tube is freed from unwanted gases during a thermal treatment by a flushing process in which a flow of inert gas enters through one opening and leaves the tube through the other, is characterized in that during the flushing process the tube communicates openly via the other of the openings with the open air and in that the pressure in the tube exceeds the atmospheric pressure.  The flushing gas may be nitrogen or a rare gas, and the final filling may be one or more rare gases, mercury vapour or sodium vapour. If a rare gas is required in the final filling it is preferable to use only such rare gas in the last phase of the flushing process. In the manufacture of a curved lamp, flushing is continued during the bending process.  The method enables the lamp manufacturing machine to be simplified since no ducts need be connected to one of the tube openings.
