Title: Improvements in valves for liquid measuring and dispensing apparatus
IPC: B67D7/52
Filed: 1945-05-05
Abstract: 637,156. Fluid-actuated valves. S.A.T.A.M. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. May 5, 1945, No. 11483. Convention date, March 20, 1942. [Class 135] A hand-actuated valve for attachment to the end of the delivery pipe of apparatus for measuring and dispensing liquids comprises a main valve 2, loaded by light and strong springs 11, 12, respectively, capable of maintaining the valve closed on its seat 3 against the static head in the delivery pipe and the static head plus the pressure head due to the supply pump, and a pilot valve 6 on a piston 10 loaded by a light spring 8 and, through a collar 16 pinned to the stem 14, by a strong spring 13. The flow into the delivery pipe from the dispensing pump is controlled by a main valve with which is associated a pilot valve as described in Specification 637,155. Hand pressure on the lever 15 results in movement of the stem 14 to the left which relieves the pressure of the strong spring 13 on the pilot valve 6 which opens and permits opening of the second-mentioned main valve. The main valve 2 is then relieved of the pressure of the strong spring 12, through the loose collar 17 and a lost-motion device consisting of an aperture 19 in the collar and a pin 20 of the shaft, so that this valve opens and permits full flow of liquid to the outlet. When the operator sees that the required volume of liquid is nearly delivered, he releases the lever 15 which results in closure of the main valve 2. The valve 6 remains open and permits small flow through the port 7, owing to the pressure difference between the face and the back of the pistons. The reduction in the flow causes closure of the second-mentioned main valve and flow thus continues through byepass around this main valve until the required volume of liquid has been delivered.

Abstract: 473,492. Induction motors. CRAIG, M. D., and MOSSAY, P. A. H. April 25, 1936, No. 11778. [Class 35] [Also in Group XXXVII] In a single-phase induction motor employing an auxiliary winding in series with a condenser for starting purposes, the connection and disconnection of the auxiliary winding and condenser is effected by means of an electromagnetic switch located in a housing 5 attached to or forming part of one of the end-plates 1 of the motor. The housing 5 is offset from the housing 3 forming a bearing for the motor shaft 4, so as to give a compact structure and to enable current to be conducted to the motor by means of two terminals only. The switch is mounted on a bracket 6 fixed to the housing 5, and comprises a U-shaped yoke member 7 carrying an iron core 8 on which the winding 9 is mounted. The two-limbed armature 10 pivots about the end of one of the limbs of the yoke 7, the shorter limb of the armature being normally maintained in engagement with the yoke by an adjustable spring 11. The winding 9 is in series with the main winding of the motor and, on closing the starting switch, the longer arm of the armature is attracted against the action of the spring to close the circuit of the auxiliary winding and condenser at contacts 12, 13. As the motor runs up to speed, the current in the winding 9 falls, until the spring 11 overcomes the attractive force of the winding and the auxiliary circuit is opened.
