Title: Improvements in or relating to polyphase rectifiers
IPC: H01L25/07
Filed: 1930-06-16
Abstract: 356,329. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Santini, D. ; 341, Avenue F, Forest Hills, Wilkinsburg, Pennsylvania, U.S.A.) June 16, 1930, No. 18424. Convention date, June 18, 1929. [Class 38 (ii).] Rectifiers for polyphase currents consist of disc units of the copper-copper oxide or like type arranged in groups in a single pile, each group consisting of an even number of units tapped at its midpoint for connection to the alternating-current line and the groups being oppositely disposed and tapped at their junctions for connection to the direct-current line. The Figure shows such an arrangement in which each group consists of two units comprising a lead washer 2, a rectifying layer and a copper disc 1. The discs are threaded on an insulated bolt 3 and connected to the three-phase terminals 6 and the direct current terminals 7, 8 as shown.

Title: Improvements in or relating to the control of feed water pumps
Inventor: MCALPINE THOMAS
IPC: F04D15/00
Filed: 1957-06-12
Abstract: 891,161. Pumps. WEIR Ltd., G. & J. June 12, 1958 [June 12, 1957], No. 18504/57. Class 102(1). [Also in Group XIII] A water feed pump 1 delivers water to a boiler 3 which supplies steam to the point of use through conduit 5 and also through a throttle valve 6 to the engine driving the pump. The throttle valve 6 is coupled by a linkage to two operating cylinders 8 and 9 containing movable members, the cylinder 8 being connected to the pump feed line 2 and the cylinder 9 being connected at either end by lines 10, 11 to the throat and entrance respectively of a Venturi passage 7 in the steam line 5. If the rate of flow of steam from the boiler 3 increases the movable member in the cylinder 9 moves and acts on the throttle valve 6 to increase the speed of the engine driving the pump, and the new pressure in the feed line 2 acts through the cylinder 8 to provide the desired pressure control of the throttle valve 6. If the water level in the boiler drops below a certain value the valve 12 is opened to connect the line 10 to drain thus causing adjustment of the throttle valve 6 to cause the driving means of the pump to run at its maximum speed. A restricting orifice 14 is provided in the line 10 to augment the pressure drop in this line adjacent the cylinder 9 when the valve 12 is opened and to prevent undue loss of steam from the line 5. Specifications 431,215, 466,613 and 509,542 are referred to.

The magnets 2 lie in the gap between the frames 5 which are provided with field windings 6 supplied with alternating current. In modifications the armatures 2 are replaced by electromagnets fed with D.C. or by iron cores or are fitted with shortcircuited windings. The field windings may be replaced by a permanent magnet and the armatures then comprise electromagnet fed with A.C.

Title: Revivification of metallic hydrogenation catalysts
IPC: B01J23/94
Filed: 1948-07-10
Abstract: Hydrogenation catalysts consisting of or containing metallic nickel, cobalt, copper or iron which have been poisoned with sulphur, selenium, tellurium or phosphorus or compounds thereof are revivified by treatment with a solution of a per-acid of molybdenum, tungsten, vanadium, chromium or phosphorus or a salt thereof and then washing and drying.  The revivified catalyst may subsequently be reduced with hydrogen.  The solution of a per-acid or a salt thereof, made by the action of hydrogen peroxide on the appropriate acid or salt, may contain excess hydrogen peroxide. In examples a poisoned nickel-on-kieselguhr catalyst is treated at 100 DEG  C. with sodium permolybdate or sodium perchromate solution. Hydrogenation reactions in which the catalysts are employed are the hydrogenation of benzene, naphthalene, phenol, cresol, xylenol and unsaturated glycerides; the production of liquid products from carbon monoxide and hydrogen; and the synthesis of ammonia. Specification 644,240 is referred to.

Title: Improvements in or relating to the screw propellers of helicopter flying machines
IPC: B64C27/615
Filed: 1920-07-05
Abstract: 146,835. Pateras Pescara, Raoul, Marquis of. July 3, 1919, [Convention date]. Steering and balancing.-Screw propellers for flying-machines of the helicopter type are arranged one above the other, rotating in opposite directions, and are provided with means for varying the pitch of the blades continuously and periodically during their revolution. The propellers are mounted on bosses 5, 6 which are mounted so as to rotate on a fixed central tube 4, and are driven by bevel gearing 16. A vertical rod 17 is movable in all directions around a universal joint 18, and is provided with universal joints 19 20 having radial rods 21, 22 passing through the tube 4. These rods are pivoted at 23, 24 to rods 28 which slide within the radial supports 29 of the blades and are attached to cables 30 which actuate worm gears 31, 32 to vary the angle of the aileron 34. The angle of the ailerons thus varies continuously during their revolution. The blades are constructed with longitudinal ribs 37, 38 and transverse ribs 36, and each terminates in a tube 39 having a screw 40 of large pitch. The mean pitch of the blades is controlled by a lever 41 operating an eccentric 42 which causes the rise or fall of sliding members 47, 49. These members carry ball bearings 50, 53, the outer ring of which is connected by rods 51 to a part 52 which is internally screw-threaded to engage the screw 40. The rise or fall of the members 47, 49 causes a radial movement of the members 52 and consequently a turning of the blades on their axes. The periodic variation of the angle of the blades displaces the line of action of the propeller thrust from its axis and enables the device to be used for propelling, steering, stabilizing, and braking.
