IPC: E05F17/00
Filed: 1932-02-19
Abstract: 397,502. Window fastenings. BAIRD, T., 124, Bothwell Street, Glasgow. Feb. 19, 1932, No. 4947. [Class 44.] A window comprises two or more sashes, B, C, D, Figs. 1 and 2, mounted in an open frame A, each sash, or each with the exception of the bottom sash D, being carried by the sides of the frame on fixed pivots 2 at the lower edge of the sash.

Patent GB-372435-A (GB)
Title: An improved device for the periodic opening or closing of an electric circuit
IPC: H04M19/02
Filed: 1931-02-17
Abstract: 372,435. Selectors responsive to code signals. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUM. PHRIES, H. E., 47A, Lewisham Hill, both in London. Feb. 17, 1931, No. 4995. Addition to 334,516, [Class 40 (iv), Telephones &c.]. [Class 40 (iv).] In a'device for periodically opening and closing an electric circuit described in the parent Specification modified for operation on low-voltage circuits a polarized relay Z, Fig. 1, is employed which is of the type which maintains its armature in the position to which it is brought when the relay is energized. In the position shown a current flows from earth over contact y<2>, condenser QA, choke ZC, and contact y<1>. As the condenser charges up, the rise of current is delayed by the series connected choke ZC and when the voltage across the condenser has risen to a sufficiently high value the relay Z operates, closing the circuit of relay Y. The contacts y<1>, y<2> are changed over and the current through the relay Z and choke ZC is reversed. The contacts y<1>, y<2> are of the make-before-break type so that during the period when they make both front and back contacts a path is closed including the choke and the relay allowing the energy stored in the choke to be dissipated, so delaying the release of the relay. Condenser QA also discharges through the relay coil with the same effect, but the predominating effect is the dissipation of energy stored in the choke. The flow of current through the relay in the reverse direction is consequently delayed, so delaying the initiation of the operation of the relay in the reverse direction. The de - energization of the relay does not affect relay Y but when it is operated by current in the reverse direction contact Z<1> is opened and relay Y is released, restoring its contacts y<1>, y<2> to the position shown. Thus a periodical delayed action opening and closing of a controlled circuit is produced. In a modification (Fig. 2, not shown), in which ordinary change-over contacts yl, y2 are employed, the choke ZC is divided, a condenser being connected across a portion of the choke and the condenser directly shunting the relay is dispensed with.

Title: An improved safety valve for air pressure systems
IPC: F04B49/02
Filed: 1929-02-21
Abstract: 329,653. Keywood, C. F. Feb. 21, 1929. Valves controlled by pilot or relay valves.- A safety-valve particularly adapted for use in connection with air compressors has a main ball valve 26 opened by fluid pressure acting on a spring loaded diaphragm 31 under the control of a spring loaded auxiliary valve 43 arranged to open in the direction of the actuating chamber. The main actuating spindle 39 is secured to a piston 37 bearing against the diaphragm which is clamped against a shoulder in the casing by a screwed ring 32. The auxiliary valve, which is loaded by a spring 44 adjusted by a plug 45 screwed into a detachable cap 45<1>, is actuated either by the pressure in the receiver 1 transmitted through passages 18<1> 18, 19 and 40, or by line pressure transmitted through the passage shown in broken lines. A spring loaded check valve 20 is interposed in the pipe line to prevent return flow. A screwed nipple 22f adapted to receive a pressure gauge is fitted with a valve 22c normally held open by a spring but adapted to close with rush of fluid on removal of the gauge. To ensure prompt closing of the main valve a local venting valve 49 closed by a spring 50 slightly stronger than the spring 38 is mounted in a cap 35 closing the actuating chamber. This valve may be positively opened by a rod 48 having a foot resting on the actuating diaphagm when the diaphragm is lifted by admitting pressure beneath it. The pressure may be supplied when an outlet valve from the receiver is operated and slowly leaks away through a leakage passage provided at 39<1>. In a modification the valve 49 is' adapted to be raised by a hand lever. The reservoir is fitted with a spring loaded ball valve 7 adapted to be moved to the open position by a ported member 14 secured to the screwed nipple 11 of the main valve casing, when the casing is screwed into position. Specification 311,548 is referred to.
