Title: Improvements in or relating to reduction gearing
IPC: G05G15/04
Filed: 1945-05-25
Abstract: 593,243. Intermittent toothed gearing. STANDARD TELEPHONES & CABLES, Ltd., FIELDING, E. C., LUKEY, R. W., and SEATH, E. G. May 25, 1945, No. 13119. [Class 80(i)] [Also in Group XXXVIII] An intermittent toothed reduction gear of the " Geneva mechanism " type comprises a driving shaft 1 with an eccentric 4 which oscillates a follower plate 8 having a pin 9 at one side guided in a fixed slot 10 and a pin 11 at the other side which engages with peripheral castellations in a castle plate 7 to move this plate one castellation in the opposite sense from that of the shaft 1 for each revolution of the shaft. In an application to radio equipment for tuning a multi-turn inductance or capacitance to any of a number of predetermined frequencies one such gear unit is provided for each of the required positions of the shaft 1, all the units being driven off this shaft. Each unit has a disc 3 fixed to the shaft with a V-notch 12 in its periphery and a disc 6 secured to the driven plate 7 freely mounted upon a hub 2 on the shaft and having a notch 13 in its periphery. Adapted to engage with the notches 12, 13 when they are in line is a peg 14 on a lever 15 pivoted at its other end at 16 and urged towards contact with a cam 20 by a spring 18. The shaft 21 of cam 20 and the shaft 1 are both driven by electric motors through electromagnetic clutches (not shown). To select any required position of the shaft 1 the motor driving the camshaft 21 is started and run until a roller 19 on the appropriate lever 15 falls into a notch in the corresponding cam 20. This movement of lever 15 operates electrical contacts (not shown) on members 22 and 23 which stop the motor and start up the driving motor of the main shaft 1. Rotation of shaft 1 continues until the notches 12 and 13 are in line when the peg 14 drops into these notches and in doing so effects a dis-engagement of the electromagnetic clutch and stops the driving motor. Thus the shaft 1 is turned a definite number of turns determined by the driven disc 6 of the operative gear unit and a portion of a turn determined by the V-slot in the disc 3, the discs of each unit being initially set to give the desired operation to be selected by cams 20. An auxiliary shaft may be geared to the main shaft 1 to operate an indicator and also to operate contacts to reverse the motor drive at either extremity of the shaft operation.

Title: Improvements in or relating to automatic sprinkler heads
IPC: B05B1/26
Filed: 1937-05-13
Abstract: 495,765. Fire-extinguishing. ATLAS SPRINKLER CO., Ltd., and CHISHOLM, D. H. May 13, 1937, No. 13572. [Class 47 (ii)] In a sprinkler head of the kind embodying a bursting bulb 6 for holding the valve 9 closed, the yoke 2 is so formed that it presses the strut resiliently against the valve. As shown, the yoke, which may be made of brass, has parallel sides and curved ends, the radius of curvature at the deflector end being less than that at the inlet end 1. When the screw 5 is tightened against the strut, a bending stress is applied to the deflector end of the yoke, which stress tends at all times to press the strut against the valve. Alternatively, the yoke may be substantially circular, or may be relatively wide and flexible at the deflector end. The cross-section of the arms of the yoke may be varied so as to localize the resilience of the arms. The valve 9 may be of copper, and the strut is supported between abutments 7, 10 with seating rings 8, 11 of copper. Reference has been directed by the Comptroller to Specifications 16019/14, 135,809, [both in Class 47 (ii)], and 409,569.

Title: Improvements in and relating to a stabilised unidirectional voltage supply
IPC: H02M7/217
Filed: 1965-03-31
Abstract: 1,047,904. Automatic voltage control. VAN DER HEEM N.V. March 31, 1965 [April 3, 1964], No.13714/65. Heading G3R. A voltage regulator comprises rectifiers 2, 3 for deriving an unsmoothed unidirectional voltage from a transformer 1, a pre-regulator switching element 5 such as a transistor or thyristor, a buffer capacitor 6, a series regulating element 7, e.g. a transistor, output terminals 8, 9, and a conventional differential amplifier 10, associated with a voltage reference source 11 in the form of a battery, Zener diode, or glow discharge tube, for controlling the element 7 in dependence upon output voltage variations. The switching of transistor 5 is controlled by a bi-stable device 12 which together with a Zener diode 15, is connected into the circuit as shown. When the unsmoothed voltage from rectifiers 2, 3 falls to zero, the device 12 is switched to a first state in which it renders transistor 5 conductive; when the voltage across the series transistor 7 reaches a maximum desired value determined by Zener diode 15, the device 12 is switched to a second state to render transistor 5 non-conductive. The pre-regulating element 5 is thus controlled so that the series element 7 is protected against excess voltage and thus excess heat dissipation.

Title: Improvements in the treatment of textile materials consisting of or containing animal fibres to reduce their tendency to felt and shrink
Filed: 1944-07-25
Abstract: The tendency of textile materials consisting of or containing wool or other animal fibres to shrink and felt is reduced by treating them with aqueous solutions of peroxides or persalts or compounds thereof capable of evolving oxygen at a pH of 8-12 in the manner described in Specification 553,923, before or after they have been treated with a sulphur-containing reducing agent such as the sulphite, bisulphite, meta-bisulphite, hydrosulphite or tetrathionate of an alkali metal, magnesium or ammonium. Preferably, dilute aqueous solutions of the reducing agent are employed.  The wool or other animal fibres, e.g. mohair, may be admixed with cotton, flax, viscose rayon, cellulose ester or ether rayon, silk, nylon or rubberised threads and the materials may be treated in the uncombed state or as slubbing, roving, yarn, top, threads or in the form of woven or knitted fabrics.  The process can be applied before or after dyeing, or the dyeing process may be combined with one of the treatments, levelness of dyeing being thereby improved.  Examples are given in which (1) woollen fabric is treated at 50 DEG  C. with an aqueous solution containing anhydrous sodium sulphite and sufficient acetic acid to reduce the pH to 7. The fabric is then rinsed and treated at 50 DEG C. with aqueous hydrogen peroxide adjusted to pH 10 by sodium silicate; (2) the order of the treatments in (1) is reversed.
