Title: Improvements in or relating to hydraulic or pneumatic control valves
IPC: F15B13/04
Filed: 1937-10-29
Abstract: 485,908. Valves. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES. Oct. 29, 1937, No. 29668. Convention date, May 8. [Classes 69 (ii) and 135] A hydraulic or pneumatic control valve comprises a pair of manually-actuated piston valves c, d which control a supply of pressure fluid from a connection f to working chamber connections z and o and the exhaust to a connection k. With the valves in their " off " positions as shown the supply passes through passages g, h, i to the exhaust and the two working chambers are also opened to the exhaust through passages l, n. On depression of one of the buttons a, b the corresponding valve c or d is actuated to supply the pressure fluid to one of the working chambers, and is held in the depressed position by a spring catch v or v<1>. On the completion of the working stroke the pressure builds up and acts against a spring-pressed piston p to move it to supply pressure fluid through a central duct and ports s therein to the end t or l<1> of the actuated valve to move this valve against the spring catch back to its " off " position. The ports s in the piston p are made relatively small in crosssection so that a certain delay is provided by the resulting throttling action to allow locking devices associated with the working chambers sufficient time to operate satisfactorily. These control valves may be arranged in groups or in series, depending upon the nature of the installation.

Title: Improvements in or relating to electric couplings
IPC: D06F79/02
Filed: 1945-11-07
Abstract: 603,959. Current-supplying stands for electric kettles, irons, etc. HALL, T. J. Nov. 7. 1945, No. 29678. [Class 39(iii)] [Also in Group XXXVII] In an electric coupling device for an electrically heated kettle, iron or other portable appliance, wherein a plug connector on the appliance engages with a current-supplying socket connector by a sliding movement of the appliance along a shelf or support, and a switch controlling the supply to the sockets is simultaneously closed by the engagement of a switchoperating member with a projection on the appliance, the pins of the plug connector do not conductively engage with the terminal sockets until the appliance has been earthed through a metallic surface of the shelf, thus preventing accidental shock to the operator. In the example, a lever 14 is operated by a metal foot 15 on a kettle when plug pins 16 on the kettle are made to engage with socket connectors 8 by a sliding movement of the kettle along an earthed metal shelf 1. The lever 14 moves links 11, 10 against a spring 13 and operates a switch arm 9 to supply current to the connectors 8, the latter being mounted in a block 7 of porcelain. For safety, the pins 16 may be insulated over part of their length so that when partially engaged with the sockets 8, only insulated parts of the pins project. The top of the shelf may be grooved to guide the feet 17 of the kettle and the bottom may be grooved to receive irons not in use. A pilot light 20 indicates when the sockets 8 are live. Cable entrances 3. 4 are provided at the back and bottom, 5 being a removable closure and 6 a flexible metallic conduit for the electric leads.
