Title: Improvements in concrete and like building construction
IPC: E04B2/56
Filed: 1921-04-20
Abstract: 183,250. Thompson, H., and Thompson, S. H. April 20, 1921. Slabs.-Double walls are built with concrete or like slabs A having at their vertical edges, on the inner face, thickened portions formed with half grooves Y of fish-tail section, the complete grooves formed when the slabs are in position being engaged by locking-bars L which are slid vertically into position. The locking-bars have flanges F with bevelled faces, the thickness of the flanges being less than the depth of the grooves, whereby the slabs may be adjusted to bring their faces into a plane. The locking-bars are made in sections, and are arranged so that their ends abut between the upper and lower edges of the slabs; transverse-air passages P are provided in the bars to connect the air spaces between the inner and outer slabs. The vertical edges of the slabs are formed with interlocking grooves and tongues X, Z of dovetail shape; the grooves and tongues are emploved both in straight portions of the wall and at corners. In order to form reveals and jambs for door and window openings, slabs are employed having one extremity returned as shown at R. Fig. 4, whereby a full groove is formed to receive the locking- bars.

Title: Improvements in or relating to electric ripple control systems
IPC: H02J13/00
Filed: 1946-04-15
Abstract: 610,688. Signalling over power circuits. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S.. April 15, 1946, No. 11480. [Class 40 (iv)] In a ripple control system in which the connection or disconnection of the load circuits of a power line is controlled by high-frequency currents injected into the line, the control current is prevented from passing a predetermined point by injecting at that point a highfrequency current which balances out the control current. As shown, the control current is derived from a H.F. generator 2 and is fed by parallel injection to the phase wire 1 over a series resonant circuit 4. In order to prevent this current being fed along the phase wire in both directions, the H.F. current is also fed by series injection to the wire on that side where no control current is required, over a parallel resonant circuit 7 comprising the transformer 8 and condenser 12. Since the H.F. voltage fed over this path is substantially equal to, and opposite in phase from, that due to the control current, no control current will flow in the direction associated with the transformer. The blocking current may be derived from a separate generator. Specification 599,051 is referred to.

Title: Improvements in or relating to fluid operated time delay devices
IPC: G04F1/00
Filed: 1958-04-15
Abstract: 861,462. Retarding action of switches. SQUARE D. CO. April 15, 1958 [May 6, 1957], No. 11891/58. Class 38 (5). [Also in Group XXXII] In a pneumatic time-delay device, a flexible diaphragm 54, Fig. 4, divides a chamber 49 from a chamber 52. The chamber 52 is in communication with the atmosphere through ports 55. In operation, a timing cycle is initiated by raising the diaphragm 54 from its normal position, Fig. 4, to its raised position, by moving a shaft 36 upwards. A needle valve 60, which meters the flow of air into the upper chamber 49, does not allow rapid exhaust of air from the chamber 49, thus air pressure in the chamber 49 progressively increases and upward movement of the diaphragm is restrained. However, the shaft 36 continues to move upwards, thus lifting a valve seat 87 off a valve portion 82 of the diaphragm 54. This movement allows the air entrapped in the chamber 49 to escape through an orifice 84 and exhaust to the atmosphere through the ports 55. When the pressure differential between the chambers 49 and 52 is relieved, a bead 85 of the valve portion 82 re-engages the lower surface 88 of the valve seat 87 in response to the bias of a valve spring 89. When the upward force acting on the shaft 36 is removed, the shaft moves downwards under the bias of an operating spring 98. A partial vacuum is created in the chamber 49 by initial downward movement of the diaphragm 54 which is relieved by air flowing slowly into the chamber 49 through a filter 69 and past the needle valve 60. The device is described as being electromagnetically operated, and controls the making and breaking of a snap switch 41.
