Title: Improvements in dispensers for powdered soap and the like
Inventor: SESSIONS MARC HARVEY
IPC: A47K5/10
Filed: 1962-05-24
Abstract: 932,879. Delivering measured quantities of pulverulent material. UNITED STATES BORAX & CHEMICAL CORPORATION. May 24, 1962, No. 20096/62. Class 106 (5). A dispenser for pulverulent material, such as powdered soap, comprises a housing 1 adapted to receive a soap container 17 and having a discharge opening 26, a removable apertured plate 8 defining a discharge chamber 22 below it and a valve plunger 4 having several measuring notches 5 in its outer surface. When the valve is raised by pressing on a reduced stem 20, the notches 5 rise above the plate 8 and fill with soap while the soap supplied to the discharge chamber on the previous downward movement of the valve discharges past the stem 20. The valve is additionally supported in a spider 10, is pressed downwardly by a spring 11 and may carry a wire 14 for breaking up any agglomerated soap. The container may have a tight fit directly in the housing or in an interchangeable bushing 2 or the housing or bushing may have screw-threads into which the container may be screwed. As shown in Fig. 15, the lower stem of the valve may be of dog-leg shape so as to be clear of the descending soap and the upper stem 13c is then of non-circular section fitting in a corresponding aperture in the spider 10 so that the valve is always assembled with the dog leg at the rear. In order to direct the soap clear of the dog leg, the notches 5 may converge forwardly towards each other. The mounting bracket 15 may be apertured so that it can be held between the container or bushing and the housing or the bracket may be integral with or fixable to the housing.

Title: Improvements relating to control systems for electric motors
Inventor: KING KENNETH GORDON
IPC: H02P27/06
Filed: 1962-05-29
Abstract: 1,020,214. Control of A.C. motors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 29, 1963 [May, 29, 1962], No. 20620/62. Heading H2J. An induction motor M is supplied from a variable frequency inverter SI which is fed from a D.C. source V, the frequency of the supply from the inverter being dependent upon the repetition frequency of pulses which fire controlled rectifiers therein, this frequency being determined and modified by signals from a pulse' generator. The pulse generator is fed with a control signal developed across resistor R in the supply to the inverter, this signal being a function of the torque imposed by a load on the motor whereby the speed is maintained substantially constant. The pulse generator comprises a relaxation oscillator formed by transistor VT2, inductance L1, capacitor C1, and controlled rectifier CR1, associated with emitter follower transistor VT3 and Zener diode MR1 as well as input transistor VT1. A monostable flip-flop circuit is connected to the relaxation oscillator through a differentiating circuit C2, R8. The flip-flop circuit comprises transistors VT4, VT5 and capacitor C3 connected with integrating resistors R12, R13, the generator circuit being completed by resistors R5, R7, and capacitor C4. A control signal from resistor R is added to a main control input signal CS supplied to transistor VT1, the capacitor C1 charging at a rate depending on the current in transistor VT2 and the rectifier CR1 being fired when the emitter potential of transistor VT3 overcomes the Zener diode MR1. The frequency depends upon the collector current of transistor VT2 and hence on the base current of transistor VT1. Negative-going pulses from the anode of rectifier CR1 drive the inverter S1, and also feed the flip-flop circuit which produces constant-width pulses, whereby a linear characteristic of frequency with respect to control current is afforded. The static inverter SI may be replaced by a frequencychanger whilst the current for controlling the pulse generator may be derived by sensing the current input of the motor.

[Class 143] Printed and perforated records, apparatus for giving.-In a weighing-machine of the kind described in Specification 182,455, [Class 143], wherein the setting of a printing-mechanism is determined by fingers moved into engagement with a stepped body set by the weighing- mechanism, auxiliary devices for otherwise recording the results of individual weighments are also controlled by the fingers. After the weighing-mechanism has come to rest in balanced condition, fingers b, one for each denomination of weight, are moved into abutment with steps a<1> on a member a set by the weighing-mechanism. Each finger is connected through gearing c, d with a type-wheel f, and with a rack x<1> having a projection x<2> controlling a bank of punches x'. Upon the upward movement of a table z, a card y carried thereby receives a printed record of the weight from the type-wheels and a perforated record from the punches, only those punches that are restrained by projections x<2> being operative to perforate the card. The sum of the individual weighments is registered by a totalizer q readable through an aperture s in the casing. The totalizer is rockable about an axis r and is moved into engagement with actuating segments m during the restoring movement of the fingers b, against adjustable stops on which the segments abut. Specification 197,102, [Class 143], also is referred to.

Abstract: 792,127. Electric heating. SANCTUARY, H. N. Feb. 24, 1956 [July 16, 1954], No. 20783/54. Class 39(3) [Also in Groups XIII and XXIX] A temperature regulating device for attachment to saucepans and like untensils includes a bimetallic strip 4 within a frame 1 and connected by links 5, 6 to a Bowden wire 7 sliding within a cable 8. The cable extends between a cap 2 and a bayonet connector 9, and in one arrangement the connector is received in a socket 10, Fig. 2, of a tap regulator 11 adjacent a gas tap 12 of a cooker, so that the wire regulates the tap when the contents of the utensil readh a predetermined temperature. The wire abuts a tap clamp 25, and a spring 14 between the clamp and regulator 11 draws the tap on, whilst an adjustable screw 15 prevents it being turned right off by the device. The latter can be swung about a pivot 17 to clear the tap when not required. Alternatively the device may be arranged to lift the base of a saucepan from an electric hot plate or may cut off the supply current. In the double hot plate arrangement of Fig. 3 in which heat passes conductively from one plate to the other, the device moves the upper plate laterally relative the lower one and in so doing the plates are vertically separated. For this purpose the upper plate 20.has a ball 22 in each corner which rides an inclined track 23 of a groove in the lower plate 21.

The N-type counter-dopant reacts with the mask on regions 37, 38 which is a thermally grown oxide, to form a glass which is etched away prior to the final drive-in step.

Abstract: 877,422. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. June 26, 1959 [July 3, 1958], No. 21293/58. Class 37. A point contact germanium device is electroformed by an alternating current of such frequency that the turnover voltage of the junction thus formed does not differ from the value that would have been attained by passage for the same time of an alternating current of higher frequency but of the same R.M.S. value. During electroforming acceptors are subject to diffusion and to drift in the electric field. For thermal acceptors, i.e. acceptor centres produced by lattice disturbances, the drift rate greatly exceeds the diffusion rate, whereas the reverse is true for conventional acceptor impurities. Independent control may be provided over the thermal diffusion and drift by use of a forming current of sufficiently high frequency. In one embodiment a pure alternating forming current is used so that the acceptors diffuse as a result of the heat generated but merely oscillate in the electric field with no resultant drift. If the alternating frequency is sufficiently high the amplitude of this oscillation will be so small that the turnover voltage of the resulting junction will be independent of the point in the cycle at which the forming voltage is cut off. Alternatively a direct-current component of variable magnitude is superimposed on the alternating current to aid or oppose the thermal diffusion in a controlled manner. In a suitable forming circuit, shown schematically in Fig. 4, 25 millisecond pulses of a 1 mc/s. current and direct current respectively are fed together to a point contact diode. Specification 747,198 is referred to in the Provisional Specification.
