Title: Improvements in or relating to apparatus for producing ionised air
IPC: H05F3/04
Filed: 1950-11-06
Abstract: 730,851. Supply systems for space discharge apparatus ; discharging static electricity. GENERAL ELECTRIC CO., Ltd., and LUCKHURST, D. W. P. Nov. 6, 1951 [Nov. 6, 1950], No. 27077/50. Classes 35 and 38 (4). [Also in Group XL (a)] Apparatus for producing ionized air, which can be used for dissipating electrostatic charges accumulating on threads during weaving operations, comprises in combination a valve oscillator arrangement producing high frequency high voltage alternating or pulsating current and a pointed electrode arrangement to which the output from the valve oscillator is supplied to produce ionized air, the pointed electrode arrangement including a conducting element, having along its length a plurality of sharp points, and a co-operating electrode. The electrode arrangement, Fig. 2, includes three rods 30, 31 and 32 carried by end-plates 33 of insulating material and arranged substantially parallel to one another in a triangular relationship. A cover 35 extends between the end plates 33. The rod 30 has along its length a large number of sharp points 34 which extend upwardly, the extremities lying below the uppermost parts of the rods 31 and 32. The rods 31 and 32 are earthed and high-frequency high-voltage A.C. from the circuit shown in Fig. 1 is fed through the lead 24 to the rod 30 to produce ionization of the air in the vicinity of the points 34. An electric wind effect is produced so that the ionized air is brought into contact with the series of filaments 36 which extend across, above and in close proximity to the rods 31 and 32. The flow of air can be augmented by supplying air to the interior of the cover 35 which may extend further around the rods. The cover 35 may be made of metal and may replace the rods 31 and 32. The use of a valve oscillator of the tuned anode feedback type is described. Other forms of valve oscillator such as a Colpits oscillator may be used. A pulsating high-frequency current may be derived from the high-frequency alternating current by rectification. The Provisional Specification describes also apparatus for producing ionized air comprising a metal chamber provided over its surface with a multiplicity of apertures, a second metal member spaced and insulated from the first metal member and provided with a number of pointed electrodes, the pointed ends of which lie within the apertures in the first member, and a high-frequency electric generator for causing ionization of the air around the pointed electrodes. The two metal members may be arranged in the form of a tube having along its length a multiplicity of circular apertures and a conducting rod disposed centrally within the tube and carrying pointed electrodes arranged to lie at the centre of each hole in the tube.

Title: Improvements in or relating to the control of spring coiling machines
Inventor: SVENSSON LARS ERIK
IPC: B21F3/00
Filed: 1968-06-07
Abstract: 1,222,411. Automatic control of spring coiling. INDUSTRIFJADRAR A. B. June 7, 1968. No.27188/68. Heading G3R. In a spring coiling machine, deviations of spring rate exceeding a predetermined value cause automatic correction of the rate of succeeding springs and still greater deviation directs the spring concerned to a separate location. In Fig. 1, wire 1 is fed to spring coiling tools 3, 5 forming springs which are compressed or expanded in turn between arms 9, 10 the movement of which is resisted and thus depends on the spring rating. If the extent of this movement indicates that the spring rating is above or below the desired value by more than a predetermined amount, a detector 14 operates a motor 6 for a short period so that tool 3 is adjusted through reduction gearing 7 in a sense tending to correct the rating of succeeding springs. If the extent of movement of arms 9, 10 indicates that the spring rating is above or below the desired value by a still greater amount which is intolerable, a detector 12 operates means to separate the spring from those which are within tolerance. The springs under test complete an electrical circuit so that the open circuit when one is missing prevents a false correction from being made.

Title: Improvements in or relating to the processing of cloth
IPC: F16D49/10
Filed: 1962-05-21
Abstract: 1,019,830. Liquid treating cloth. SANDO IRON WORKS CO. Ltd. May 21, 1962 [May 20, 1961; Dec. 23, 1961], No. 27295/65. Divided out of 1,016,172. Heading D1L. Apparatus for use in processing cloth (e.g. desizing, scouring, bleaching or dyeing) comprises a vertically arranged, elongate tank 1 for temporarily storing the cloth while being treated and means for folding the cloth into the upper end of tank on to the uppermost of a series of supports 6,6<SP>1</SP>. The supports at each level are mounted on shafts 12,12<SP>1</SP> which are intermittently rotated through one revolution to allow the cloth to fall to the level below. As shown the shafts 12,12<SP>1</SP> are drivingly connected to a shaft 26 which carries a crank arm 18 slotted to slidable recieve, a bearing 19. A shaft 20 in the bearing 19 carries, at one . end a cam roller 24 and is connected at the other to the piston rod 22 of a hydraulic or pneumatic arrangement. The roller 24 is moveable in a fixed track 25 and when the supports 6, 6<SP>1</SP> are in the position shown the roller rests in one of the two right angled corners of the track. When the hydraulic or pneumatic device is operated piston rod 22 is extended or retracted and the roller 24 is moved through half it cam track to the other right angled corner. Thus shaft 26 is rotated through 180 degrees and the gearing is such that this causes a 360 degrees revolution of the shafts 12,12<SP>1</SP>. If each support 6, 6<SP>1</SP> extends either side of its associated shaft the gearing is arranged to turn the  shaft through 180 degrees at each motion. To prevent shock gear 16 is split into inner and outer parts joined together by springs.

Title: Magnetic information storage system
IPC: G11C11/06
Filed: 1963-07-10
Abstract: 1,042,347. Magnetic storage devices. SPERRY RAND CORPORATION. July 10, 1963 [July 23, 1962], No. 27373/63. Heading H3B, A binary zero is stored in a ferrite core by maintaining the core flux at one saturated remanent state, and a binary one is stored by applying a short duration pulse which partially switches the core flux towards the other saturated remanent state, followed by a larger amplitude pulse of opposite polarity which switches the core flux back to its initial saturated state. Due probably to the formation of domain walls providing nucleation centres when a binary one is stored, the subsequent switching of the core flux to the opposite saturated remanent state to read out the stored information induces an output voltage in a sense conductor of higher amplitude and steeper rise time if a binary one is stored rather than a binary zero. The partial switching of the core flux may be 50% of the possible flux excursion. In a modification, Fig. 3, a cross field is applied to a ferrite core 11 by a winding 21, the direction of the cross field being reversed when the polarity of the writing pulses in input winding 12 is reversed.

Title: Improvements in or relating to vacuum brake apparatus for railway trains
IPC: B60T13/46
Filed: 1921-10-15
Abstract: 189,606. Luard, E. S., and Rawlings, V. P. Oct. 15, 1921. Fluid-pressure.- In vacuum brake apparatus for railway trains, of the kind comprising an additional reservoir and a valve for automatically connecting this reservoir to the train-pipe to maintain the vacuum therein under running conditions and for effecting a rapid release of the brakes, the valve is held to its seat in the " brakes-on " position of the driver's valve bv air pressure. An additional exhauster is provided for the reservoir. The equipment includes the usual parts, namely :-brake cylinders 2, 3 on the locomotive and tender respectively, having their lower chambers connected to the trainpipe 1 and their upper chambers connected by pipes 5, 6, 7 to a reservoir 8 and by pipe 10 to the driver's valve 11 and exhauster 9. In addition there is provided a reservoir 14 and an exhauster 16 therefor, preferably a steam driven vacuum pump. The reservoir is connected to the train pipe 1 through a valve 18 which comprises the chambers 29, 30, Fig. 2, connected respectively to the train-pipe 1 and the reservoir pipe 15 and separated by the valve proper 36. Diaphragms 37, 38 connected to a valve spindle 35, enclose a chamber 31 connected by pipe 20 to a cock 21 which can be actuated by a lever 23 and sliding rod 24 so as to connect the chamber 31 either to the atmosphere or to the reservoir pipe 15. The diaphragm 38 is open to atmosphere on its upper side and is larger than the diaphragm 37 which is equal in effective area to the valve 36. Under running conditions, a spring 28 acting on the cock 24 holds the cock 21 in position to connect the chamber 31 to atmosphere. If the exhauster 9 fails to maintain the necessary vacuum in the train-pipe 1 and chamber 29 of the valve 18. the valve 36 is unseated by the increase of pressure in this chamber and the spring 43 acting against the atmospheric pressure on the upper side of the diaphragm 37, until the vacuum in the train-pipe is restored. When the handle 26 of the driver's valve is moved to " brakes-on " position, an arm 25 thereon by engaging the rod 24 moves the cock 21 into position to connect the chamber 31 of tha valve 18 to the reservoir 14 thereby the tendency of the train-pipe pressure m the chamber 29 to open the valve 36 is rendered ineffective by atmospheric pressure acting on the larger area of the diaphragm 38. In the release position of the driver's valve, the cock opens the chamber 31 to atmosphere, as in the running position and the exhauster 9 is thus supplemented by the reservoir 14 and exhauster 16 to effect a rapid release of the brakes. A higher vacuum is preferably maintained in the reservoir 14 than the normal vacuum in the train-pipe.
