Title: Improvements in or relating to multi-way valve fittings for water-softeners
IPC: B01J49/75
Filed: 1945-03-05
Abstract: 597,521. Purifying water. BAYS, E. F. March 5, 1945, No. 5499. [Class 46] [Also in Group XXIX] A multi-way unitary valve fitting for a water softener has intercommunicating front and rear waterways or chambers, and valves of the conventional screw-down type for controlling the direction and volume of flow of the water. The fitting may comprise a casting 10, Figs. 1, 3, having upper and lower chambers 12, 13 communicating through ports 20, 21, 22, 23 controlled by screwdown valves 27 with rear chambers 16, 18, the chamber 16 having a drain outlet 17 and the chamber 18 a hard-water inlet 19. In normal operation, the hard water entering the chamber 12 passes through the outlet 14 to the upper end of the softener and thence from the lower end thereof through the inlet 15 of the lower chamber to the valve-controlled soft-water outlet 24. During revivification of the softening material, the water entering the chamber 13 passes through-the port 22 into the chamber 16 and thence to the drain outlet 17. The valves controlling the flow of the water are arranged in quincunx. In a modification, the fitting consists of a tubular casting having frontal sections 12, 13, Fig. 4, and rear sections 16, 18 and provided with a cover-plate 34 having apertures for the valves and held in position by Easi-clean covers on the valves.

Abstract: 288,248. Goodyear Tire & Rubber Co., (Assignees of Snyder, R. W.). April 7, 1927,. [Convention date]. Vulcanizing by continuous processes.-Articles to be vulcanized are carried by a conveyer through a roughly U-shaped bath 10, 5, 12 cbntaining liquid which is heated by a steam-jacket 6. The head of liquid in the vertical parts maintains the necessary pressure on the horizontal part.

Patent GB-480487-A (GB)
Title: Improvements in optical devices for mixing light
IPC: G02B27/14
Filed: 1937-02-24
Abstract: 480,487. Optical systems; colour photography. OPTICOLOR AKT.-CES. Feb. 24, 1937, Nos. 5571 and 5572. Convention dates, Feb. 24, 1936 and April 9, 1936. [Classes 97 (i) and 98 (ii)] An optical light-mixing system particularly intended for colour photography with lenticular films, comprises a prism arrangement having a light-entrance surface and a light-exit surface, and a number of reflecting and partly-reflecting surfaces by which the entering light is divided into a number of sections and the light from each section is caused to issue from the exit surface distributed over the whole of the said surface. Fig. 1 shows a prism having its entrance and exit faces at right-angles to each other and having a totally-reflecting surface F<3> and internal partly-reflecting surfaces F1, F2 to divide the entrance face into three sections El, E2, E3 and the exit face into three sections Al, A2, A3. The surface F1 reflects one-third of the light incident on it from either side and the surface F2 reflects half the incident light so that, if the light incident on each section E1, E2, E3 is considered as twelve units, the light emerging from each section A1, A2, A3 will also be twelve units made up of four units derived from each of the sections E1, E2, E3. When the device is used in colour photography with a colour-band filter, an objective provided with the filter is placed adjacent the exit face with the zones of the filter registering with the sections A1, A2, A3. Fig. 4 shows a form in which the entrance and exit faces are parallel and there is no lateral displacement of the emergent beams relatively to the incident beams. This form comprises totally-reflecting surfaces F1, F4 and partlyreflecting surfaces F2, F3. The left-hand half of the surface F2 reflects one-third of the incident light and the right-hand half is wholly reflecting ; the surface F3 reflects half the incident light. In order to minimize errors due to inequalities in the light paths within the system, a pair of prisms, for example, of the kind shown in Fig. 4 may be disposed side by side and relatively reversed so that between them they cover the entrance pupil as shown in Figs. 5a, 5b, 5c. A diaphragm preferably having a rectangular opening is disposed near the entrance face. The device may be placed in a vessel containing an immersion liquid in which the colour filter may also be disposed. The partly reflecting surfaces may be produced by etching the glass surfaces in strips to produce shallow depressions, so that when these surfaces are placed in contact the depressions provide air spaces and total internal reflection takes place at the glass-to-air surfaces.

Title: Drive means for control members in nuclear reactors
IPC: G21C7/16
Filed: 1960-02-17
Abstract: 919,171. Controlling reactors. SIEMENSSCHUCKERTWERKE A.G. Feb. 17, 1960 [Feb. 17, 1959], No. 5621/60. Class 39 (4). A nuclear reactor control rod 1 is moved by hydraulic pressure acting on a piston 4 in a tube extending into the reactor and its rate of movement is controlled by the effect of a magnetizing coil 10 on a bundle of metal rods 5 attached to the control rod. To each coil is connected a generator 11 which supplies a series of pulses when the control rod is to be moved and a steady current when the rod is to be held still. The hydraulic pressure may be supplied by the reactor coolant: the upper valve 9 supplies to the piston a pressure either higher or lower than that on the other side of the piston; the lower valve 9 by-passes the piston, and downward movement takes place under the influence of gravity, upward movement being hydraulically produced. German Specification 1,052,000 is referred to.

[Class 83 (ii)] [Also in Group XXI] The Specification as open to inspection under Sect. 91 describes various methods of manufacturing projectiles. Thus, a blank having a cylindrical interior cavity and walls which are thinned down in the region of the base 1c as shown in Fig. 13 (Cancelled) may be placed in a mould having the profile indicated by broken lines and caused to conform with the shape of the mould by the action of gas or hydraulic pressure. The forward portion of the projectile with thin walls may be shaped by the same process. The body of the projectile can also be moulded in a single operation by starting with a cylindrical hollow blank with walls of increasing thickness from rear to front, the blank being deformed by hydraulic pressure so as to shape the body with the profile shown in Fig. 16 (Cancelled). This subject-matter does not appear in the Specification as accepted.
