In a washing machine, control means comprising an electric circuit (Fig. 2, not shown) are arranged to open a cold filling valve 17 to partly fill a container 12 with cold water, then to close that valve and open a hot filling valve 18 to admit hot water to the container until it is full unless a predetermined water temperature is first reached in the container, in which case the valve 18 is closed and the valve 17 is re-opened by the control means to complete the filling of the container with cold water. During addition of hot water a drum 11 is slowly rotated to agitate the water in the container. The water is heated by an electric heater 35, controlled by a thermostat 36, if the predetermined temperature is not reached during the filling operations. Valves 17, 18 are operated by solenoids and connected to a cold water supply 19 and a hot water supply 20, respectively, and are also connected to the container by a common pipe 23. Level responsive switches 30, 31 are connected to the common pipe by pipes 32, 33, and are arranged to operate when the container is full and partly full, respectively. The drum is fitted with an impeller 13, both of them being driven by a motor (not shown); and the drum may be driven at high speed for spin drying. In the electric circuit (Fig. 2, not shown), a series of manually operated and cam operated contacts are arranged to complete circuits through which the valves 17, 18, the motor and the heater 35 are controlled by the level responsive switches and the thermostat 36. The cam operated contacts are controlled by a stepper device which advances a cam through steps or angles when certain contacts in the system close at the end of each operation in the machine. Filling the container in the above manner, or filling the container with hot or cold water only, may be selected by means of the manually operated contacts. When filling with hot water only is chosen, one of two additional sets of contacts in the thermostat may be selected to heat the water to 60C., or 80C., when the container is full. Specification 877,429 is referred to.

Abstract: 769,005. Automatic circuit-breakers. ENGLISH ELECTRIC CO., Ltd. Feb. 25, 1955 [Dec. 4, 1953], No. 33770/53. Class 38(5) A device for tripping a circuit-breaker if the contacts are closed at a speed lower than a predetermined rate, comprises a slotted link 17 secured to the breaker operating mechanism by a pin 18 and carrying a spring-biased striker 20, and a spring- biased flywheel 13 having a pin 14 which engages the slot in link 17, so that the latter's position depends both on the position of the operating mechanism and on that of the flywheel. In the normally open position (Fig. 2) striker 20 engages a stop 19 on link 17 and rotation of the flywheel is prevented by engagement of pin 14 with the end of the slot in link 17, and as the operating mechanism is moved, pin 14 comes out of engagement with the end of the slot and the flywheel rotates until a pin 22 on it engages an abutment 23, the striker 20 not engaging a trip lever 24 if the speed of opening has been sufficient (Fig. 4), but if the speed is insufficient and the pin 14 and flywheel 13 have accelerated to their final position before the breaker opening movement is completed, the position of link 17 will be such that the striker 20 will engage lever 24 and trip the breaker (Fig. 3). For resetting from the position shown in Fig. 4, which corresponds to the end of a closing operation whether tripping or normal closing has taken place, the breaker operating mechanism is moved back to its original position, and during the return movement of lever 17 the striker 20 is initially supported on lever 24 which is prevented from clockwise rotation by a stop 25.

Abstract: 189,665. Simmance, J. F. Dec. 15, 1921. Thermometers.-In thermometers of the bi.- metallic strip type, in which compensation for variations in atmospheric temperature is effected by using two expansion elements so coupled together as to be equally and oppositely affected by such variations, the temperature to be measured being communicated to only one of the elements, the operative element 3 is adjustably attached to a rod 6 to which is adjustably attached a rod 7 resting on a roller 8. The rod 7 is connected by a rod 9 to the compensating element 10 adjustably carrying a rod 12 to which is attached a cord 13 operating the indicator. Deformation of the element 3 due to variations in atmospheric temperature produces bodily displacement of the element 10, which neutralizes the deformation of this element so that the net displacement of the rod 12 is zero. According to the Provisional Specification means may be added for applying additional corrections; for example, when the temperature to be measured is that due to combustion of a gaseous fuel supplied at a known rate, variations in atmospheric pressure may be compensated by including a collapsable container in the connection to the indicator, so that the measured temperature corresponds to a standard pressure of the fuel.
