Patent GB-744610-A (GB)
Title: Needle positioning device for sewing machines
IPC: D05B69/22
Filed: 1953-01-21
Abstract: 744,610. Sewing-machines. SINGER MANUFACTURING CO. Jan. 21, 1953 [Jan. 30, 1952], No. 1720/53. Class 112. [Also in Group XXIV] A sewing-machine has primary and secondary (slow-speed) driving mechanisms, the latter including a continuously-rotating electric motor, with control means for bringing the needle to a predetermined position by means of the secondary mechanism. The invention is described in connection with a machine which is driven through a clutch element 34 slidable on its shaft 26, which also carries a cam 59 to open contacts a, b when the needle is in its lower and upper positions respectively. The element 34 is normally spring-pressed into engagement with a pulley 29 belt-driven through the usual clutch and brake arrangement on the shaft of an electric motor controlled by a treadle 77 so that when this treadle is depressed the machine is driven by the motor, and when the treadle is released the drive is held stationary and the pulley 29 acts as a brake on the machine. The treadle 77 is connected to the clutch-operating lever 69 through an arm 75 pivoted on the lever and biased to a position midway between stops 78 by a spring 80. When the treadle is released from the running position to stop the drive, the arm 75 closes a switch 81 to energize, through contact b, an electromagnetic clutch element 44 which is continuously rotated at slow speed by a secondary electric motor ; the element 34 is thus drawn away from the stationary pulley 29 into engagement with the element 44 and the machine is thus driven at a low speed until the contact b is opened when the needle reaches its upper position, the electromagnet being then de-energized to allow the element 34 to return into engagement with the pulley 2a and thus stop the machine. If it is desired to stop the machine with the needle in its lowest position, the treadle is " heeled " to operate a changeover switch 83 to bring the electromagnet under the control of the contact a, a further reversal then being possible by a change-over switch 85 actuated by moving a presser-lifting knee-lever 87 beyond its presser-lifting position. Slow stitching may be performed by oscillating the treadle between the neutral and " heeled " positions to produce successive half-revolutions of the machine. In a modified arrangement, Fig. 8 (not shown), the switch 85 is replaced by a double-pole manual reversing switch (113) and the switch 83 by a similar switch (110) actuated by a knee-lever, and a manual switch (114) is provided to connect the two sides of the reversing switch, so that the electromagnet is fed through both contacts a, b and continuous slow running is thus obtained until the switch 114 or switch 81 is opened. The switch 81 may be placed on the mains side of the rectifier 92. Specifications 694,769; 744,652 and 744,660 are referred to.

Title: Improvements relating to the production of microporous material
Inventor: DUDDY JOSEPH CHARLES
IPC: H01M50/417
Filed: 1952-01-24
Abstract: In the production of stock for the preparation of microporous articles, a finely-divided starch and a thermoplastic resin which will at elevated temperature sufficiently soften in the absence of a plasticizer to coat the starch are blended together in the absence of solvent at an elevated temperature with a continuing wiping action under pressure, the temperature being below that which produces charring of the starch.  Polyethylene is specified when the elevated temperatures are 220 to 250 DEG  F., and the ratio by weight of starch to polyethylene is between 1 to 1 and 4 to 1. Solid fillers such as dry powdered sugar may be present in the mixture.  The mixture may then be shaped, immersed in an aqueous bath, the temperature raised to produce expansion of the starch particles and the expanded particles leached out of the mixture. Alternatively, the mixing may be continued after the starch is dispersed in the softened resin until the amount of moisture present is reduced and then the temperature raised while mixing until the starch is partially dextrinized after which the leaching out operation is performed. Specification 576,659 is referred to.

Patent GB-396072-A (GB)
Title: Improvements in or relating to lubricators
IPC: B61F17/26
Filed: 1932-01-27
Abstract: 396,072. Lubricators. BLISS, J., 30, Cheapside, London. Jan. 27, 1932, No. 2514. [Class 12 (iii).] The oil reservoir 15 pf a steam engine lubricator has an oil outlet fitted with a self-closing valve 24 which is opened for the passage of oil by a steam-operated device 26, the supply of steam to which is independent of the regulation of the steam supply to the engine. Steam is supplied to the device directly from the boiler or other source by a pipe having a manuallyoperated control valve. The lubricator shown is of the condenser feed type. Steam in the inlet passage 12 passes to the condensing chamber 11 whence the condensate passes through a conduit 13 and past a ball-valve 14 to displace oil in the reservoir 15 into the pipe 23. The passage of oil into a conduit 16 and thence to the sight-feed jet and outlet conduit is normally prevented by the self-closing ball valve 24. The ball, however, is pushed off its seat 25 by the stem 33 of a piston 32 when steam is admitted to the device by a conduit 30. The device 26 has bores of three different diameters, the smallest accommodating the stem 33, the middle one the piston 32, and the largest a double-conical enlargement 34 of slightly less diameter than the largest bore. When the lubricator is working, the upper conical surface of the enlargement contacts the shoulder between the largest and intermediate bores to seal the oil conduit 16 against entry of steam, whilst in the non-operative position, the lower conical surface of the enlargement seals the conduit 30 against the entry of oil by contact with a seating 28. The lower end of the device 26 is fitted with a drain outlet 37 having a spring-pressed drain valve 35 which automatically closes when the lubricator is working. Specification 5095/96, [Class 12, Bearings &c.], is referred to.

Patent GB-325958-A (GB)
Title: Improvements in apparatus for controlling the voltage ratio of electric transformers
IPC: H01F29/04
Filed: 1929-01-25
Abstract: 325,958. West & Co., Ltd., A., and Bergmann, F. Jan. 25,1929. Transformers. - Tapchanging switches for transformers are actuated and controlled by means which provide for changing each transformer separately and also for changing a group of transformers in common. Each of the tap-changing switches has its own motor capable of acting independently under local control switches, and also capable of being connected so as to follow the movement of a common master-controller actuated by a pilot-motor. Fig. 4 is a circuit diagram of the arrangement for three tapchanging switches (not shown). Each of the individual actuating motors M can be started locally by a push-button RP, provided that a change-over switch RC has been set on its upper contact; when thus started a motor runs until the push-button is released, exact stoppage upon the next tap being determined by a maintaining connection through a " tracer switch " TR. To lower the voltage, the motor is started in the opposite direction by another push-button LP associated with a two-way switch LC. When group control is required, the two-way switch is put on its lower contact, thereby connecting the motor through a set of hunting-contacts on a local control drum SD to a group master-controller MS; the local motor will then run until its control drum has reached a position corresponding to that of the group master-controller, the " tracer switch " acting as before to determine exact positioning. The pilot-motor PM moves the master-controller any required distance under the control of push-buttons PRP and PLP. Fig. 5 shows transmitting-mechanism whereby each of the motors M, running continuously while its circuit is closed, imparts continuous movement to its control drum SD and intermittent movement to a shaft 11 geared to the corresponding tap-changing switch. A spur-wheel 19 with toothed and plain portions intermittently drives a pinion 22 having concave arc-shaped portions the breadth of which is half that of the rim, the pinion being at rest and being locked against rotation while the concavities are traversed by the smooth parts of the spur-wheel. Similarly geared intermittent pinions 23, 24 transmit movement to cranks 25, 26 actuating spark-taking oil-switches associated with the tap-changers. A cam 28 actuates the " tracer switch." A clutch CM allows the parts to be disconnected from the motor and connected for actuation to a handle 29.
