Title: Improvements in or relating to shock absorbing devices
IPC: F16F9/26
Filed: 1930-09-17
Abstract: 363,390. Shock-absorbers. DELCO PRODUCTS CORPORATION, 329, East 1st Street, Dayton, Ohio, U.S.A.-(Assignees of Parsons, J. C. ; 1800, Roscoe Street, Chicago, U.S.A.) Sept. 17, 1930, No. 27793. Convention date, Oct. 23, 1929. [Class 108 (iii).] In an hydraulic shock-absorber of the type in which an operating arm reciprocates - a piston in a double acting cylinder and in which spring- controlled passages in the piston control the flow of liquid, a spring- controlled valve protruding into a passage provides at all times an orifice of constant size through which a limited flow of liquid can take place until the pressure rises sufficiently and opens the valve further. In the construction shown in Figs. 2 and 4, the piston 4 is reciprocated within the cylinder 2, 3 by an arm 7 connected-to the operating lever 17 and engaging between plugs 57, one of which is held up by the spring 43. Flow of liquid takes place freely into each cylinder through a one-way valve 66, but outward flow into the central reservoir 5 takes place through the restricted orifice formed between the valves 47 and the plugs 41. Each valve is formed with a collar 53 which limits the closing movement and also provides an abutment for a spring 54. The force exerted by the spring 54 may be adjusted by screwing the plug into or out of the piston. The construction provides a restricted orifice of constant area between the valve and the plug, but the valve yields when the pressure is excessive due to rapid movement of the piston. Any liquid passing the valve 51 is conveyed to the other end of the cylinder through the passages 38, 35. The spindle of the operating shaft 61 is supported by two spaced bearings 11, 15 in the casing as shown in Fig. 3, and the cover 13 retains the spindle in position through the spring- controlled plunger 25. In a modification, the throttling means described above is provided at one end only, the two ends of the cylinder being further connected by a ball valve which fits its recess so closely as to exert a throttling effect when off its seat. Balls of different diameter may be used according to requirements.

IPC: F26B17/02
Filed: 1946-09-17
Abstract: 612,090. Drying apparatus. AKTIESELSKABET VOLUND and BRABAEK, J. Sept. 17, 1946, No. 27822. [Class 34(ii)] Material in paste form is placed in a thin layer on a base, and dried by subjecting the layer to one or more zones of rapid flowing separate currents of air, which are at a lower temperature than the base, thus cooling and drying the material which is simultaneously being heated by the base. A preferred form of apparatus consists of an endless belt 4 on which is delivered a thin film of material from a silo 2, through feed rollers 3. Gas burners 10 heat the belt, and over the latter a casing 5, comprising a number of air inlet slits 6, is arranged to be raised and lowered in relation to the belt. Atmospheric air is drawn through passages 6, and passes between the belt and the partition surfaces facing it, Fig. 3, parellel to the belt motion, and flows out through intermediate passages. The material is removed from the belt by a scraper 15, and transferred to a conveyer 9 for further drying.

Patent GB-829091-A (GB)
Title: The production of uranium and uranyl sulphate
IPC: C22B60/02
Filed: 1945-10-25
Abstract: Slags obtained by the reduction of a uranium halide with a metal such as sodium, potassium, magnesium or calcium, and separation of the uranium in metallic form from the slag, are treated by crushing the slag, roasting it in air at 600-1000 DEG  C., thereby oxidizing the uranium and converting it to uranate, and thereafter grinding the roasted product and heating it at 200-300 DEG  C. with sufficient concentrated sulphuric acid to react with the fluorides and expel fluorine as hydrogen fluoride and to form alkaline earth metal sulphates and uranyl and uranium sulphates.  The product may then be digested with water to dissolve the uranium as uranyl sulphate, an oxidizing agent such as air, nitric acid, a permanganate, chromate or peroxide being added to convert any residual uranium sulphate to uranyl sulphate. The residual sulphuric acid may then be neutralized by an alkali or alkali and earth metal hydroxide or carbonate to a pH between 2 and 5 whereby calcium sulphate is precipitated together with iron. A purified solution of uranyl sulphate results.  The uranium may be precipitated as sodium uranate or as uranium carbonate or peroxide, particularly according to the process of Specification 829,088.  According to an example, a uranium slag containing magnesium and fluorine resulting from the manufacture of metallic uranium from the tetrafluoride, was crushed and roasted in air at 700-800 DEG  C.  The roasted slag was cooled, ground and mixed with about three times its weight of 98% sulphuric acid and the mixture passed to a retort having an internal temperature of about 250 DEG C. until hydrogen fluoride is no longer evolved.  The solid sludge produced was then mixed with water and air was bubbled through to agitate and oxidize the tetravalent uranium to uranyl sulphate, the last remnants of uranium sulphate being oxidized by hydrogen peroxide.  The mixture was then heated to 90-95 DEG  C., thereby decomposing any uranium peroxide and converting it to uranyl sulphate, and thereafter the solution was adjusted to a pH of 3.7 by adding calcium carbonate.  The mixture was heated to 95-100 DEG  C. and separated from the iron containing solids by filtration. On cooling to 40 DEG  C. further precipitation occurred and the purified uranyl sulphate solution was recovered.

Title: Improvements in and relating to systems of electric motor control
IPC: B60L15/00
Filed: 1923-11-10
Abstract: 228,643. British Thomson-Houston Co., Ltd., Hastings, H. C., and Tuppen, E. B. Nov. 10, 1923. Master control systems, electromagnetic; controllers, actuating.-In a motor starting arrangement, movement of a master controller to different positions determined at will either automatic acceleration under the control of a current-limit notching relay, or non-automatic acceleration independent of the relay, which in the second alternative is temporarily by-passed. The arrangement comprises a master-controller M, a motor controller Y driven by a pilot-motor N, and a notching relay C of the kind described in Specification 144,612. The Figure shows the circuits and contacts for effecting the required operation of the controller, the main contacts and power circuits being omitted. Movement of the master controller to the second position starts the pilot motor which actuates the motor controller in automatically positioned steps as far as its sixth or last series notch, subject to intermission after any step by the main current coil of the notching relay. If however the master controller is set in its third position, current is sent to a coil 56 which makes a by-pass connection in the notching relay, and allows one non-automatic step of the main controller. By moving the master controller back again to the second position and then forward to the third position another non-automatic step is allowed and so on. After the sixth notch of the main controller, further progress can only be made by setting forward the master controller to its fourth position. which allows automatic acceleration up to the full parallel notch; non-automatic progression in this stage being obtained by setting the master controller on its fifth position, and continued by using the fourth and fifth positions alternately.
