Filed: 1926-05-21
Abstract: 268,572. Pulsometer Engineering Co., Ltd., and Bj÷rnstad, J. May 21, 1926. Impeller blades.-Cutting blades 6 mounted on a rotary shaft 1 are arranged in relation to the suction branch-pipe 2a so that any solid matter that can pass along the suction pipe with the liquid can reach the cutting blades and be acted upon in conjunction with the stationary blade or blades 7, without jamming in the suction pipe as when cutting blades project into the area of the pipe. As shown in Figs. 1 and 3, the cutting rotor is arranged with its axis perpendicular to a plane that is median to the branch 2a of the suction pipe the rotor extending across the whole width of this branch pipe. The rotor blades 6 form extensions of the impeller blades 4, and the driving spindle is mounted horizontally. The stationary blade 7, adjustable by a screwed spindle 8, is placed below the centre line of the pump and exceeds in width the diameter of the suction branch 2<a>. By this arrangement, any solid material cut up tends to fall away from the impeller and thereby keep the clear space between the impeller blades. The clearance between the casing and the cutting rotor increases beyond the point 10<a>. The impeller and cutting rotor may be formed as separate castings arranged end to end and secured upon and driven by the driving spindle 1. The driving spindle may be arranged vertically, with horizontally-arranged suction inlet and delivery outlets. Specification 26913/10 is referred to.

Title: Improvements in and relating to the braking of induction motors
IPC: H02P3/24
Filed: 1950-05-25
Abstract: 670,856. Control of A.C. and D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., SHARP. H., and PETCH, T. H. Nov. 16, 1950. [May 25. 1950] No. 13215/50. Class 38 (iii). An induction motor IM is mechanically coupled to a, direct-current motor DCM which is supplied from a Ward-Leonard generator G. Braking of the induction motor is provided by disconnecting it from the alternating-current supply and supplying its primary winding with direct-current from exciter E through contactor C. The braking-effect may be increased by adjusting the excitation of field winding F4 to reduce the generator voltage, thus increasing the current passed from the motor DCM to the generator. This produces a greater excitation of exciter field winding F1 and a heavier direct-current excitation of the .induction motor. Increase of the generator voltage leads to decrease of the braking-effect, and, if the generator voltage is made greater than that of the motor DCM, the latter will exert a driving-torque, a rectifier R1 preventing energization of the field winding F1 under these circumstances. A rectifier R2 by-passes the winding F1 and rectifier R1. The rectifiers may be replaced by contactors and the exciter E by other forms of amplifiers.

IPC: C21D8/02
Abstract: 133,131. Hadfield, Sir R. A. Aug. 17, 1917, [Convention date]. Plates and sheets; helmets.-Thin steel sheets suitable for protection against bullets or shrapnel in the form of helmets, oody shields, or protective sheeting on aircraft, are made from a slab oi manganese steel which is reduced to a sheet by a succession of rolling operations, the sheets being then annealed, and finally the annealed sheets raised to a high temperature and quenched in cold liquid. The steel comprises iron containing 10 per cent to 17 per cent of manganese and 0.9 per cent to 1.4 per cent of carbon with other elements such as silicon or copper as described in Specifications 124,817 and 125,157, [both in Class 82 (i), Metals, Extracting &c.]. The molten manganese steel is cast into ingots which are allowed to cool from the bottom upwards, the upper part of the ingot being maintained in a molten state until the lower part has solidified. The ingot is converted into a slab by hammering, pressing or rolling at a temperature of about 1050‹ C. to 1080‹ C. Surface imperfections are removed from the cooled slab by grinding. The slab is now cut into shorter lengths and each slab is converted into sheets by a succession of rolling operations at a temperature of 1030‹ C. to 1040‹ C., the temperature of the finished sheet being about 850‹ C. The slabs are then annealed in a non-oxidising atmosphere, before being cut into sheets of the required size. These slabs are then heated above the floor of a heating furnace to about 950‹ C. to 1050‹ C. and quenched in a cold liquid, this operation not occupying more than 2 or 3 minutes. To obtain helmets, a flat circular blank, cut from slabs obtained as above is lubricated round the edge and pressed to the required shape.
