Title: Improvements in or relating to small rotating field electric motors
IPC: H02K7/16
Filed: 1928-02-08
Abstract: 285,018. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Franþaise pour l'Exploitation des ProcÚdÚs Thomson- Houston). Feb. 8, 1927, [Convention date]. Void [Pulished under Sect. 91 of the Acts]. Alternating - current motors; motors, supporting and mounting; mounting rotors.-A small rotating-field motor for driving textile spindles and other use, consists of a cylindrical laminated stator wound on its outer periphery and a bowl-shaped rotor surrounding the stator and carrying a winding on its inner periphery. In the form shown in Fig. 1, the laminated, cylindrical slotwound stator A is supported on a stem F secured in a frame C, the upper part of which carries a bearing D for the rotor spindle B. This spindle runs in a footstep bearing E in the stem F. The rotor consists of an inverted bowl G either made entirely of steel or carrying a laminated magnetic structure within its bore. This bore is slotted for either a squirrel-cage winding or, in the case of a synchronous motor, two coils housed in two recesses on a diameter in place of distributed slots. Fig. 2 shows a form in which the stator A is secured on a tubular support B within which is the rotor shaft running on a steel plate M in a cap N at the lower end of the tube B. The motor may be attached to a spinning frame by means of a bracket C to which the tube B is secured.

Title: Improvements in or relating to shaft positioning devices and mechanisms comprising a plurality of such devices
IPC: F16H37/00
Filed: 1949-02-14
Abstract: 685,688. Adjusting radio apparatus. PHILIPS ELECTRICAL, Ltd. Feb. 14, 1949 [Feb. 17, 1948], No. 3985/49. Class 40 (v). [Also in Group XXIV] In a shaft positioning device as for tuning radio transmitters or receivers and comprising a shaft to be positioned 24 driven through an overload clutch 35, 39 permitting continuance of driving after the shaft 24 has been stopped, the clutch is arranged on a shaft parallel to and beside the shaft 24 in order to reduce the axial dimension of the device to a minimum. The device "A" comprises, in the embodiment shown, a plurality of locking discs 45 of which only one is shown, and which are adjustably preset in fixed relation to the shaft 24 and their peripheries are each engaged by an appropriate one of a number of stop pawls 46 of which a selected one is rendered operative by a spring (not shown) and a pawl selector 49 such as is disclosed in Specification 653,419. On rotation of the selector 49 to a selected position by the tuning means (not shown) through a shaft 56 and gears 55, 53, 51, the shaft 24 may be driven through a shaft 58, gears 57, 21, the clutch 35, 39 and gears 33, 43 until a notch in the selected disc 45 is engaged by its pawl 46, whereupon the shaft 24 and the electrical element (not shown) attached thereto are stopped in the desired position, while the clutch 35, 39 overruns. For tuning a number of components, the invention is applicable to a mechanism comprising a plurality of such devices arranged side by side, a further one being shown at " B," and to this end the driving wheel 21 on the clutch shaft 19 drives a transmission wheel 23 loose upon shaft 24 for engagement with the driving wheel of the next device, e.g. 22, to effect a gear train drive of all such devices from the single driving means 57, 58. In such a mechanism, the clutch permits the drive to be continued until all the devices have been positioned should this not be simultaneous. A gear train 53, 51, 54, 52 also effects common selection of all the devices from a single tuning control. It may be desired to couple further devices at any point on the periphery of the gear-wheels, and to obviate fouling of the rods 31, 32, &c. spacing the end plates bearing the shafts, each end plate comprises two pieces 70, 71 which are reversible and interchangeable so that the lugs 61, 62 supporting the rods of each device may be arranged in any of a number of positions to clear the gears of the adjacent devices.

Title: Improved separable fastener
IPC: A44B19/40
Filed: 1940-03-05
Abstract: 547,663. Sliding-clasp fasteners. WAHL BROS., Inc. March 5, 1940, No. 4061. Convention date, Feb. 16, 1939. [Class 44] In a sliding-clasp fastener having interlocking spirals 9, 10 the material of the spirals, preferably " plastic," is of uniform segmental crosssection, the straight position of the section being disposed internally and oblique with respect to the axis of the spiral. The coils are somewhat flattened to provide elongated " loops" which interengage over more than half their major dimension. The gap between adjacent turns is slightly less than the width of the coil material measured parallel two the length of the stringer. The spirals are of non-uniform pitch, the transverse end portions of the " loops" which are presented towards the other spiral having a smaller pitch angle than that of the adjacent side portions. The spirals may be connected to the tapes 5, 6 by cords 7, 8 passed through the coils and stitched to the tapes, or the turns of the coils may be passed through ladder-like apertures in the tape which is then folded longitudinally in known manner. When the stringers are to be entirely separable the turns of each spiral near the end are less elongated so that they do not interlock, these ends being secured in end fittings 34, 32, Figs. 12, 13, the latter being removably inserted in the former.

Filed: 1969-01-24
Abstract: 1,216,063. Alkali metal dichloroisocyanurates. AZOTE & PRODUITS CHIMIQUES S.A. 24 Jan., 1969 [24 Jan., 1968], No. 4312/69. Heading C1A. An alkali metal salt of dichloroisocyanuric iC acid is prepared by mixing more than one molecular proportion of wet crystals oftrichloroisocyanuric acid with one molecular proportion isocyanuric acid and with an alkali metal hydroxide, carbonate or bicarbonate to provide three atomic proportions of alkali metal and then adding an aqueous solution of tri-(alkali metal) isocyanurate in the amount required to react with the excess trichlorocyanuric acid. Preferably, the wet crystals contain 6-20% by weight of water. The addition of the aqueous solution of the tri-(alkali metal) isocyanurate may be controlled by measurement of the pH or the redox potential of the reaction mixture, the addition being such as to maintain the pH or the redox potential (as the case may be) at a value corresponding to the complete formation of the desired alkali metal dichloroisocyanurate. The preferred pH value when the sodium salt is being produced is 5À90À1 and the corresponding redox potential is 9555 mv. If desired, the process may be carried out continuously.

A circuit for disconnecting a load 6 from a supply St when the voltage is outside a determined range comprises a device VSt equipped preferably with Schmitt trigger circuits comparing the voltage at St with a reference source (not shown) which normally delivers a positive voltage at lines 3, 4. When the voltage is above or below the range, a negative potential appears at 3 or 4 rendering T4 conductive and after a time determined by timing pulses delivered to terminal 2, transistor T5 conductive also. A positive pulse is then applied through a capacitor C1 and diode D3 which turns bi-stably arranged transistor T3 off and T2 on, thus cutting off transistor T1. Relays AL may be provided for indicating the state of the bi-stable transistors T2, T3. When the voltage returns to normal a positive voltage on lines 8, 9 reverses the state of the bi-stable circuit.
