Abstract: 571.897. Stud and slab walls. MADGER, A. W. Nov. 29, 1943, Nos. 19892/43 and 675/44. [Class 20 (iv)] Walls are built by erecting posts 5, 5a, and applying panels 11 having flanged edges permitting positioning by lateral movement and having rib-and-groove or chamfered or like horizontal edges to maintain them in co-planar relationship. One edge of a panel may have a U-groove, Fig. 14, about which the panel is swung into engagement with a post at the opposite edge. The topmost panel is secured by wedge-shaped pieces 17, Fig. 14, secured together over a rib. The panels may be applied to the posts so that the flanges 6 lie on opposite sides of the posts alternatively. Where three or more walls meet, Fig. 13, the post is thicker than the panels to permit introduction of the panels without interference and the grooved or flanged edges of the panels may be cut away at 8 as shown in Fig. 7 to permit of interfitting.

Abstract: 585,809. Projection printing apparatus. RADIO CORPORATION OF AMERICA. Nov. 29, 1943, No. 19898. Convention date, Oct. 31, 1942. [Class 98 (i)] In projection printing apparatus for printing sound-film records, the two films are driven by a common driving mechanism at a linear speed greater than the normal speed of reproduction, the films being supported at the printing point by separate drums, each driven by its film independently of the other and coupled with fly-wheels forming substantially independent mechanical filters. The negative film 1 and print film 2 are propelled by sprocket-wheels 10, 11 and 12, 13 respectively which are driven from a single source of power through worm and helical gearing. The films are carried past the optical system 6, passing over smooth drums 4, 5 to which are coupled fly-wheels or rotary stabilizers. Flexible film loops 7, 8 are provided to smooth out small rotational differences in the sprockets 11 and 13 and the drums 4, 5. The speed of the films may, be increased either by substituting a motor of higher speed, by change of gearing, or by inserting a change-speed arrangement comprising pulleys of different diameters and a driving belt. Specifications 316,320, [Class 97 (i)], 415,184, [Group XXXVIII], and 428,505 are referred to.

Title: Improvements in auto-reclosing electric circuit-breakers
Inventor: TRENCHAM PETER ROLAND HENRY
IPC: H01H75/06
Filed: 1958-06-24
Abstract: 933,602. Automatic - reclosing circuitbreakers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 27, 1959 [June 24, 1958], No. 20144/58. Class 38 (5). An automatic-reclosing circuit-breaker has a rotatable crank 31 connected to an operating spring mechanism 28 which recloses the breaker after an opening operation and drive means 37 energizable in response to opening movement of the breaker to rotate the crank to charge the spring mechanism. When the opening operation is complete, the crank goes overcentre and rotates in the same direction to reclose the breaker. In the arrangement shown, a latch 8 is released on the energization of a trip coil 21 to permit linkage 3 . . . 7 to collapse under the bias of an opening spring (not shown) causing a bell-crank lever 1 to open the main circuitbreaker contacts (not shown). The lever 1 displaces a prop 23 so permitting a spring 27 to move a plunger 22a upwardly until a flange 22b on the plunger abuts a flange 26b on a cup 26. The plunger 22a is connected by a link 22 to the linkage at 15 and the links 5, 6 and 7 return to the position shown before reclosing commences. The opening movement of the bellcrank lever 1 causes contacts A to close to energize a drive motor 37 which through gears 36 and ratchet and pawl mechanism (not shown) turns the crank 30 in the anti-clockwise direction until it goes over-centre. This permits the spring 28 to force down the plunger 22a and so turn the bell-crank lever 1 to reclose the main contacts, the continued rotation of the crank 31 in the anti-clockwise direction being permitted by the ratchet and pawl mechanism. Auxiliary contacts B are closed, a prop 33 is moved by a cam 32 to close contacts Y so that the motor 37 is energized to drive the crank 31 and cam 32 to the position shown, in which the spring 28 is charged and the crank is held against clockwise rotation by the prop 33. Should the circuitbreaker be closed on to a fault, it will trip open and remain open, preferably in the manner described in Specification 933,603. Contacts L may lock-out the circuit-breaker after a number of operations as described in Specification 933,601.

Abstract: 125,907. Schneider et Cie. Aug. 19, 1918, [Convcntion date]. Ordnance.-A tube, such as a gun barrel, to be subjected to hydraulic pressure in the process known as " self-hooping " is supported between two cross-heads A, B, which are pierced with ducts to admit the liquid and to allow of the escape of the air. The cross-heads, as shown in Fig. 1, are connected by tie-rods E, and are supported by rollers A<1>, B<1> mounted on rails D. The rollers B<1> are larger thar the rollers A<1>, thus tilting the tube. One form of connexion between the cross-heads and the tube is shown in Fig. 3. The differential piston H, I has a duct N for the admission of the fluid, and rings J, K of hard rubber or the like are provided to form close joints. The metal locking-ring J' and the forcing ring L are pierced to admit fluid to the rings J, K. The outlet pipe f may be closed by a screw plug G, and a rubber ring O with locking-ring O<2> forms a tight joint. The joints are subjected to the pressures set up in the directions indicated by the arrows 1, 2, 3, 4. In the modified form of joint shown in Fig. 6, the piston P has a head Q. The ring R forms the joint between the piston and the tube, while rings U, V form the joint between the piston and the cross-head. Fluid is admitted through the passage p<1> to the chamber U<3> while the chambers t, w communicate with the air. In another modified form, two pistons are employed at the inlet side, and the outlet plug is secured in a plug screwed on the tube and bearing on the cross-head B.
