Inventor: WALKER EDWARD ALEXANDER
IPC: F16B39/08
Filed: 1950-09-20
Abstract: 688,314. Locking rods. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 19, 1951 [Sept. 20, 1950], No. 23085/50. Class 80 (iii). A spindle 3 of an instrument is locked in an adjusted position by means of a slotted plate 5 secured at 14 to the instrument panel 2 and resiliently gripping the spindle by means of the sides of the slot 7. The locking can be released when desired by the insertion of a flat bar or screwdriver in the slot to expand it. In an alternative arrangement a rotatable pin with a flattened portion is mounted so that the flats lie in the slot of the plate but do not engage it. When the pin is turned by, for example, a screwdriver the slot is forced open to release the locking action. In another arrangement the slotted portion of the plate is of curved form so that a direct pressure parallel to the axis of the spindle opens the slot.

Abstract: 6 0 0,6 3 5. Wrapping-machines. ROSE, A. G., GILBERT, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. Oct. 10, 1945, No. 23228. [Class 94(i)] In a machine for wrapping razor blades or similar blade-like articles, the articles are fed from a source of supply by an intermittently rotatable transfer member comprising two or more feeding members each adapted in turn to seize an article by contact with its upper surface from the source of supply and transfer it to the wrapping elements. In one form of the invention adapted for use at the bladefeeding station of the machine described in Specification 593,368 each blade 13 is fed in turn from the base of a magazine 14 by a pusher 16 to a position adjacent a transfer member 27 having four radial feeding members 28 each adapted to pick up a blade from the pusher 16 by means of suction applied to the members 28 by means of a vacuum pump, a suction chamber 55 in a fixed pillar 34, and ports 54 leading thereto from a suction chamber 53 in a sleeve valve 33 axially slidable on the pillar, and ports 52 in the members 28. The members 28 are carried on a sleeve 29 freely mounted for axial and rotary movement on the sleeve valve 33, which is also provided with a port 81 through which a blast of air from a pipe 82 can be delivered to the members 28. The sleeve 29 and sleeve valve 33 are operated to move axially by rollers actuated by cam mechanism and engaging annular grooves 32, 37 respectively, and the ports are arranged in conjunction with these axial movements so that suction is applied to each member in order to lift the blade and retain it while rotating in two steps of 90 degrees each, thereafter lowering it into the wrappers in a pocket 12 of a pocket wheel 11, and to cut off the suction and admit a blast of air through the port 81 in order to strip the blade from the member. The transfer member is rotated by a Geneva mechanism adapted to maintain its two members in engagement throughout the axial movement of the member 27. At the intermediate station through which each blade passes, a detector device controlled by cam and spring mechanism operates to contact the underside of the blade, and in its absence to close an electric circuit, resulting in the faulty package being later rejected. Specification 588,070, [Group II], also is referred to.

Title: Improvements relating to the production of crimped yarns of synthetic material
IPC: D02G1/02
Filed: 1954-08-12
Abstract: 775,075. Finishing yarns and threads. INVENTA AKT.-GES. FUR FORSCHUNG UND PATENTVERWERTUNG. Aug. 12, 1954 [Aug. 12, 1953 ; June 21, 1954], No. 23494/54. Class 120 (3). In a process for continuously crimping yarns of synthetic material, a stretched yarn, when in a moist and swollen or unswollen state, is given a twist of at least 1500 turns per metre during which the moisture contained in the yarn is evaporated by heat to set the twist, optionally it is cooled e.g. to below 100‹C, back-twisted and reeled, the twisting and reeling being carried out at a lower tension than the back-twisting. In the apparatus shown, an untwisted or slightly twisted stretched yarn in a damp condition (10-20 per cent. moisture content) is taken from a spool 1a on a spindle 1 by feed rollers 2, through a heating device 3, cooled by .gases directed from a nozzle 6, twisted and back-twisted by a false-twist tube 4 comprising means for braking the yarn, such as described in Specification 775,076, and coiled or reeled on a bobbin 8. In the embodiments, Figs. 2 and 3 (not shown), a dry yarn is moistened by passage through a steam chamber or over a moistening roller which transfers wetting or wetting and swelling agent(s) thereto before entering the rollers 2. The crimping effect is enhanced if, on leaving the rollers 5, the yarn is tensioned, to a greater extent than during reeling, by passage through rollers rotating at higher speed than the rollers 5.

Title: Control systems for battery chargers
IPC: H02J7/00
Filed: 1973-05-17
Abstract: 1453860 Battery charging systems J A MACHARG 17 May 1974 [17 May 1973] 23535/73 Heading H2H A battery charging apparatus comprises means for repeatedly switching the charging current ON and OFF in order to provide an opencircuit terminal voltage of the battery during the OFF periods; means for providing a signal to control the magnitude of the charging current; means for extracting the 'IR drop', as defined in the specification, from the open-circuit terminal voltage of the battery; means for differentiating the decay of the open circuit terminal voltage during the OFF periods; means for deriving a voltage which is a function of the differential; means for comparing this voltage with a standard voltage and means for using the difference between the two voltages to modify the control signal thereby to control the magnitude of the charging current. A timing circuit H includes an operational amplifier OP-A the output of which goes alternately positive and negative which controls a switching unit G comprising transistors TR1, TR2, TR3 so that a signal appears at terminals OE to control the ON and OFF periods of the battery charging current. The output of the amplifier OP-A is also fed to a differentiator B which includes a transistor TR4 and to a peak memory circuit C comprising a transistor TR5. When the output is negative, i.e. when the charging current is OFF, the transistor TR4 is turned on for a very short period so short circuiting a resistor R6 and transistor TR5 conducts to the charge capacitor C5. During this time no differentiation occurs, thus the 'IR' drop is extracted, after which both transistors TR4, TR5 become non-conductive. During the remainder of the charging current OFF period, the decay in the open circuit voltage is differentiated, the capacitor C5 charges to remember the peak of the differentiated voltage. The voltage across the capacitor C5 is compared, in a comparator D comprising transistors TR8, TR9, with a standard voltage developed in a circuit E having a zener diode 24 and a potentiometer R9. The output of the comparator D is integrated in a circuit F comprising a resistor R10 and a capacitor C6 the output of which circuit is taken to the base of transistor TR2 so as to modify the operation of the switching unit G. The output from the switching unit G is used to control a thyristor connected between the battery and a rectified AC charging supply. The system thus controls the charging of a battery according to the degree of gassing thereof. A filter circuit A is provided to remove the rectified AC component from the charging current. In other embodiments two differentiating circuits are used, one of which differentiates the decay of open circuit voltage without the extraction of the 'IR' drop and the input to the integrator may include an 'AND' circuit. The apparatus maybe modified so that any batteries of any number of cells may be charged and in which the charging current may be limited so as to prevent damage to the charging apparatus. Reference is made to Specifications 1,225,802 and 1,360,089.
