Title: Improvements relating to guards for power presses
IPC: F16P3/04
Filed: 1947-01-11
Abstract: 620,246. Machinery guards. BROOKS & CO., Ltd., J. B., and RICHARDS, R. A. Jan. 11, 1947, No. 1017. [Class 80 (iv)] In a press guard of the type in which inital movement of the operating lever of the machine closes the guard, the clutch cannot be engaged until the guard is completely closed. Upon depression of the clutch pedal 15, the guard 8 is closed through a cable 13 and links 30, 12, and at the same time a link 18 on the guard turns a cam 20 through a link 19 until a depression 21 in the cam comes in line with a spring-pressed plunger 24, Fig. 6, carried in a fixed casing 23. The top 27 of this plunger is then released from a hole 28 in an extension 29 of the clutch controlling member 17. This member is then free to be operated on further depression of the pedal 15 to start the machine.

Title: Improvements relating to the removal of vanadium and/or sodium from petroleum and hydrocarbons of petroleum origin
IPC: C10G45/04
Filed: 1951-01-15
Abstract: Sodium and/or vanadium are removed from crude petroleum or from hydrocarbons of petroleum origin by contact with bauxite under such conditions of temperature and pressure that the sodium and/or vanodium are deposited on or incorporated in the bauxite, the presence of hydrogen during the contacting with bauxite being optional in the case of sodium removal but necessary for the removal of vanadium.  The preferred conditions for sodium removal are a temperature of 780 DEG  F. and a pressure of 100-200 p.s.i.g., while the preferred conditions for vanadium removal are a temperature of 780 DEG  F. and a pressure of 800-1,000 p.s.i.g.  There is a consumption of hydrogen during the removal of vanadium, but excess hydrogen may be recycled.  Since hydrofining or cracking catalysts are poisoned by sodium and vanadium, the process may be employed for the preparation of improved feedstocks for hydrofining or cracking. Thus, crude petroleum or petroleum residues may be freed of sodium and vanadium before hydrofining, and petroleum wax distillates may be freed of sodium and vanadium before cracking.  In the examples, crude petroleum, petroleum residue or petroleum wax distillate are contacted with bauxite so that sodium and vanadium are deposited on or incorporated in the bauxite.  It is indicated that some vanadium is removed even in the absence of hydrogen and that the process effects some sulphur removal.  Specifications 682,387, 710,342 and 729,303 are referred to.

Abstract: 907,428. Thermoselective devices. WESTINGHOUSE ELECTRIC CORPORATION. Jan. 10, 1961 [March 2, 1960], No. 1043/61. Class 37. A thermo-electric assembly (for generating electricity, heating or cooling) comprises a plurality of thermo-electric elements with a flexible conductor secured to the body of each, thermally and electrically conductive straps interconnecting the elements, and compressible biasing means for extending the conductors. A thermo-electric generator comprises a thermal radiator 12 the inside of which is heated, e.g. by a burner (Fig. 1, not shown) and to the outside of which are secured thermoelectric elements 34. Elements 34 are alternately of P- and N-type semi-conductor material and at one end are interconnected by flexible copper straps 40 (Fig. 3) in a series, parallel or series-parallel ladder arrangement. Secured to the other end of each element is a flexible conductor (e.g. a braided copper cable) surrounded by a compression spring 44, and connected to a further set of copper straps 46. The ladder assembly is arranged with straps 40 in good thermal contact with radiator 12 and straps 46 in thermal contact with a second thermal radiator 14 having cooling fins 18. The springs are in compression and support radiator 12 centrally within radiator 14. The radiators may be of ceramic or metal, and if of metal are electrically insulated from straps 40, 46 by coating the radiators with alumina, glass or other ceramic material, silicone rubber, high-temperature paint, or thin strips of mica or mica paper. A layer of glass fibre lagging may be arranged between elements 34 to prevent heat transfer from radiator 12 to radiator 14. The elements may be encapsulated in glass, thin metal films or ceramics for protection.

[Also in Group XXVIII] Variable-stroke mechanism, particularly for reciprocating pumps, in which one end position of the reciprocated member is always the same, comprises a plate 29 which is oscillated about a fixed but adjustable pivot 30 by means of a strap member 26 coupled thereto by a pin 28 and actuated by an eccentric 25 on a driving- shaft 22. A connecting-rod member 36 is pivotally connected to the plate 29 and coupled by a pin 24 to the member 23 to be reciprocated. The pivotal axis of member 36 on plate 29 is constrained to move in an arc about pin 30 of a radius equal to the length of member 36, and by rotary adjustment of a support member 31 for pin 30 about the axis of shaft 22 by a worm and segment 33, 32, the orientation of this arc is varied to vary the movement transmitted by member 36 to member 23. To give a comparatively sudden movement at the beginning of the suction stroke of a pump in order to unseat the suction valves the pin 28 is provided with a certain amount of clearance in the eccentric strap 26 and a cam 38 with a depression 39 secured on the eccentric 25 is adapted to cooperate with the pin 28 so that at the " dead " point the pin 28 enters momentarily the depression 39 and is then moved suddenly forward.

[Class 78 (iv)] [See also Group XVI] A device for charging and emptying multipleplaten presses comprises frames a provided with superposed carrying structures such as sets of rollers b for receiving plates of material on carrying sheets c to be slid into and withdrawn from the press. A passage is provided along the middle of the frame for movement of a vertical beam e which pushes in the plates or pulls them out, as by hooks. The beam is moved by conveying appliances such as racks d mounted in the top and bottom of the frame. The beam may carry a motor f driving toothed wheels h engaging the racks d. The conveying appliances may alternatively be screws or ropes. The frames are inclosed on their long sides and top and bottom, being open only at their narrow ends. A frame a is mounted on both the charging and discharging sides of the press. For charging the frame a, it may be moved horizontally and laterally of the press and charged at the end remote from the beam e. In other forms the frame is charged at the other end and the beam e is moved away by lateral rocking or sliding or vertical sliding or swinging the beam and racks d about a vertical pivot. It may be disconnected from the racks d and hoisted by a carrier. To facilitate charging, the frame may be lowered step by step by hydraulic cylinders k and the plates may be run in on a roller track l.

Warp threads, uniting. - In warp twisting-in machines of the type wherein the end portions of the warps to be twisted together pass upwardly, each having a cross therein, to clamps on a carriage u, the crosses being maintained by horizontally-projecting and horizontally-reciprocating hook-bars j, which draw back edgeways, first one and then the other of the crossed sheets of threads and thereby release one by one the outermost threads, turning half-revolutions between their drawing-back movements, means are used to cause a considerable gap A between the outermost thread separated and the main body of threads drawn back. The warps are clamped to pivoted clips on the carriages u, which are held forward by springs v. The warps are acted upon by a stop w on a forked slide movable in ways on the underside of the projecting arm p<1> of a structure p, which is moved vertically by mechanism described. The forked slide is provided with a roller engaging a fixed cam z, so that when the structure p is depressed (the hook bars being then forward, in which position they are rotated), the cam z causes the stop w to press back the warps to the right, but when the structure is elevated, the warps are moved by their clamps to a position forward (to the left) of their former position, whereby a considerable gap results between the thread released by the rotation of the hook bars and the main body of threads in each warp. Moreover, the reciprocation of the warp-holding devices breaks down the filament connection between each released warp thread and the body of the warp. The threads are guided by rods q and a fork i and are fed to the twisting-devices S by a rotating spiral t, whilst a swinging finger t' holds back the main body of warp.
