[Class 125 (iii)] A closure for a container outlet comprises a cap which is pivoted for lateral angular movement about an axis inclined at such an angle to the face adapted to be engaged by the cap that angular movement of the cap to uncover the discharge or filling aperture also raises the cap above this face. As applied to a collapsable tube 1, Figs. 1 and 2, the neck 2 is provided with a collar 4 and a closure cap 11 having a gasket 9 the cap 11 being hinged to the collar 4 and the contact faces of the lugs 12, 14 being inclined to the plane of the upper end 8 of the collar 4 so that as the cap 11 is rotated from the closing position about the pivot 16 it is raised above the plane 8 of the collar 4. In a modification for use as a radiator cap, the closure comprises a circular cap 19, Fig. 4, having a gasket 22 in a central seat 21 and secured by screws 23, 24 to a cover 27 the cap 19 being secured to the neck 17 by a thimble 29 having an annular flange 30 and locking lugs 31, 32 which engage under the flange 18. The flange 30 serves to clamp a collar 35 and gasket 36, the collar 35 being formed with an extension 41 having an inclined wall 43, Fig. 7, to which is pivoted by a rivet 44 an inclined wall 45 of the cap 19. A gasket 46 and a spring washer 47 are provided.

Title: Improvements in Multi-stage Centrifugal Fans and Pumps.
Inventor: FRAME WILLIAM JOHNSTON
IPC: F04D1/06
Filed: 1917-09-03
Abstract: 120,401. Frame, W. J. Sept. 3, 1917. Multi-stage centrifugal pumps.-In a multi-stage pump having a rotor provided with two or more central fluid inlet eyes leading to two or more stages of rotor blades acting in series within one compartment of the pump, and in which the fluid passing through any one stage of rotor blades does not cross the path of the fluid passing through any other stage of blades within the rotor, the fiuid, in passing to one of the central eyes of one of the rotor stages, crosses the path of the fluid passing to another central inlet eye of the rotor, or to the discharge. Fig. 6 shows a four-stage pump having two impellers, each with two stages, the discharge from one stage of each impeller being axial, and from the other radial. The fluid from the inlet d passes through openings in the inward flow guide passages n to the suction eye of the first stage g. In passing along the passages n to the second stage h it crosses the first inlet path. From the second stage it passes by the conduit w to the third and fourth stages, which are similar to the first two stages. The final discharge 13 may be formed between the diffuser q from the last stage but one and the inlet to the last stage 11 as shown in Fig. 8, which refers to a three-stage pump, having all the discharges from the impeller radial. Several modified combinations of impellers are described and shown.

Abstract: 645,683. Thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 8, 1945, No. 3252. Convention date, Oct. 2, 1942. [Class 39 (i)] An electron discharge device comprises a resonant cavity which is formed by an isolated section of a hollow pipe dielectric wave-guide, in which standing electromagnetic waves are established, a transverse wall within the cavity composed of two metal members spaced from each other and defining an aperture resonant at the resonant frequency of the cavity, and an electron discharge path which includes at least a part of the aperture. As shown in Fig. 3, an evacuated rectangular cavity resonator 19 includes a transverse wall structure defining a resonant aperture 24, tuned substantially to the natural resonance frequency of the cavity. The cavity resonator is an integral number of half-wavelengths long. The upper portion of the transverse wall comprises an anode block 25 insulated from the cavity walls by a spacer 26, and the lower portion comprises a hollow metallic U-shaped member 29 in contact with the cavity walls. The member 29 is insulated from the block 25 by an intervening portion of the spacer 26. A cathode 32 is located between the upright walls of the member 29, and provides with the anode block 25 and a metal partition 30 at each end of the cathode, the boundaries of the resonant aperture 24. The device may be operated as a detector, or as an oscillator, in which case the electron transit time is chosen to be an odd number of quartercycles of the frequency of the waves established in the cavity. In another embodiment, Fig. 5, a double diode detector, or frequency-changer, comprises hollow metallic members 45, 46 constituting the anodes, and defining the resonant aperture 44. The members 45, 46 are insulated from the cavity resonator walls by spacers 47, 48. A cathode 51 is located midway between the horizontal faces of the metal members 45, 46. In a modification the metal members are each replaced by a pair of metallic partitions directly mounted on the cavity walls in which the anodes are located. Wire or mesh shielding grids may be mounted across the partitions to define the top and bottom of the resonant slot. Control or modulating wire or mesh grids, shielded by the partitions, may also be provided.

Patent GB-396770-A (GB)
Title: Improvements in or relating to the manufacture of aliphatic acids, anhydrides and ketones
Filed: 1932-02-09
Abstract: Acids, anhydrides, and ketones are produced by thermally decomposing salts of aliphatic acids in presence of inert diluent compounds boiling (at atmospheric pressure) at temperatures at least as high as the reaction temperature.  Suitable diluents are high-boiling hydrocarbons and ethers such as dibenzyl ether, phenyl benzyl ether, diphenyl ether and naphthyl aryl ethers, which may boil above 250 or 300 DEG  C.  The aliphatic acid salts may be admixed with normal salts of strong mineral acids but not with dehydrating reagents which react therewith such as salts of pyrosulphuric acid or salts of phosphoric acids of lower hydration than of orthophosphoric acid as described in Specifications 136,574 and 299,342, [both in Class 2 (iii), Dyes &c.].  The aliphatic acid salts may be dry or may be associated with water, and the heating may be effected in a stream of indifferent gas or vapour such as air, carbon dioxide or nitrogen or the vapour of benzene or petroleum ether, and ordinary, increased or diminished pressure may be employed.  Dilute aliphatic acids may be converted to salts for instance of copper, nickel or chromium, water being then removed to the desired extent for instance by the methods described in Specification 390,825, and the removal of water may be effected after mixing with the high-boiling liquids.  In an example dilute acetic acid from cellulose acetylation is heated to 80 DEG C., and cupric oxide is gradually added, cupric acetate crystallizing out on cooling; the crystals are added to a petroleum fraction boiling at 290-330 DEG  C., the mixture being heated to 90 DEG  C. to remove water, and then to 280 DEG  C. to liberate acetic acid.  The process may also be applied to the production of acetone from calcium acetate, and the production of butyric or propionic acids or anhydrides or the corresponding ketones. Specifications 381,963 and 382,673 also are referred to.
