In an electricity generating plant including a main generator 11 having a rotary driven shaft 13 and an auxiliary generator 15 having a rotor 16 mounted coaxially on the shaft 13, the stator 17 of the auxiliary generator is mounted to move angularly about the shaft axis in response to the torque load of the auxiliary generator, and such movement is opposed by restraining means and operates over- and/or under-speed control or alarm means. As shown, the rotor 16 is of the permanent magnet type and the stator 17 is carried in a journal bearing 18 formed on the main generator stator and movable between limits determined by a stop 26 on the latter and the movement permitted by a tension spring 23 forming the restraining means. In operation, should the main generator rotate at too high or too low a speed, the stator 17 moves anticlockwise or clockwise respectively of Fig. 1 whereby a cam 34 pivots a switch arm 35 to close its contacts 37 or a stop-bar 25 engages a bell-crank 31 to close its contacts 32 which contacts 37 or 32 respectively make over-speed or under-speed control or alarm circuits not shown. The main generator is driven by a " Kaplan type hydraulic turbine 12 having turbine blade adjusting mechanism 14, and the auxiliary generator may have two separate armature windings which supply respectively auxiliary equipment such as a governor motor and a dummy load, e.g. resistances 28 which latter provides the required torque load and may be adjustable to vary the speed control characteristics ; the dummy load alternatively may be embodied in the armature winding. In the Provisional Specification the restraining means may be counterweights.

Title: Improvements in or relating to sheet-delivery mechanism of printing machines
IPC: B65H29/34
Filed: 1921-03-09
Abstract: 179,372. Linotype & Machinery, Ltd., and Spence, F. March 9, 1921. Delivery apparatus.- Relates to sheetdelivery mechanism for printing - machines of the kind comprising a number of bars supported by a reciprocating carriage, which bars during the inward travel of the carriage pass between the delivery tapes and during the outward travel receive a sheet from the tapes, the sheet being swept off the bars on to the delivery board during the next inward travel of the carriage by the action of pivoted fingers lifted to engage the inner edge of the sheet and subsequently lowered out of the way of the carriage during its next outward travel, and consists in the combination of sheet-pusher fingers adapted to swing about an horizontal axis and an oscillating slotted arm for imparting said swinging motion, characterized by the fact that the slot in the oscillating arm is non-radial to the axis about which it oscillates, positive stops acting on the fingers being dispensed with so as to minimize trouble from accidental breaking of the fingers. As shown, the bars are supported by the reciprocating carriage 3 and pass on the inward travel of the latter between the tapes 5 and tape rollers 6. The fingers 8 are secured to a rock-shaft 9 mounted in brackets 10 adjustable along rods 11 at opposite sides of the machine, and are rocked by means of an arm 14 secured to the shaft 9 and formed with a non-radial slot 15 engaged by a stud 16 on one arm 17 of a bell-crank lever. Carried by the other arm 18 of the lever is a swivelling block 19 clamped by a screw 21 to a rod 20 connected to a pivoted lever 22 adapted to be actuated by a roller 24 on the carriage 3 when the latter reaches the limit of its outward travel, whereby the fingers 8 are raised, as shown in Fig. 2, in readiness to sweep off the sheet lying on the bars 1 when the carriage travels inward again. Another lever 26, pivoted at 25 and having a projection 27 resting on the arm 17 of the bell-crank, is raised at the same time as the fingers 8 are lifted and takes up a position in the path of the roller 24 so that by the time the sheet has been swept off the bars 1 and on the further inward movement of the carriage 3, the roller 24 engages the lever 26, thereby lowering the fingers 8 into the prone position. A rod 28 is pivoted to the rocking- arm 14 and passes through the slotted swivelling pivot 25 of the lever 26, and is encircled by a coil spring acting between the shoulder 30 and the pivot 25 to retain the fingers 8 in their terminal positions. The arrangement of the stud 16 and slot 15 may be reversed, the former being carried on the rocking-arm 14 and the latter provided in the arm 17 of the bell-crank.

Filed: 1939-03-14
Abstract: 530,778. Calcium sulphate cements; moulds. BEAN, M. March 14, 1939, No. 8230. Drawings to Specification. [Classes 22 and 87 (ii)] Moulds for casting metals &c. filter plates tiles &c. formed from calcium sulphate cements are treated to increase the permeability by forming within the body nucleated crystal groups by dehydrating the body to form calcium sulphate hemilydrate and then rehydrating to form the dihydrate. The dehydration may be effected by heating in a dry or moist atmosphere or in an autoclave by steam under pressure at above 110‹ C. The rehydration is effected by exposing the body to the atmosphere while still wet. The body may be dehydrated while immersed in dry sand or sawdust which retains sufficient moisture for the rehydration. Moisture may be removed from the surface during the rehydration to obtain a fine-grained coating. The body is dried and may be heated to 300‹C. to remove all the water of crystallization without affecting the granular structure. Where the mould consists of interfitting parts, the recrystallization may cause the parts to unite. The calcium sulphate may be mixed with talc, asbestos, silica, granular material, clay or a deliquescent salt such as calcium chloride ; both an accelerator and a retarder for the setting may be added. For casting magnesium alloys a small proportion of sulphur, boric acid, or a fluoride may be included in the mix Or be coated on to the surface.

Title: Improvements in or relating to forging and shaping metals
IPC: B21K1/22
Filed: 1942-06-17
Abstract: 558,123. Producing forgings. ARON, H. June 17, 1942, No. 8329. [Classes 83 (ii), 83 (iii) and 83 (iv)] Forgings, for example produced by electrical upsetting or by a combination of such upsetting and die pressing, have unrequired metal such as flashes removed by hot milling or filing or are brought to a special shape by hot milling. After milling further forging may be effected. When rods are headed by the known process of feeding a rod 11, Fig. 1, through electrodes against an abutment 15, this becomes worn at 18 producing unwanted metal on the forging. The rod is taken by trays whilst still at red heat and whilst supported on a rest 19, Fig. 2, is turned about for removal of the surplus metal by a cutter 20. The trimmed blank is then dropped in a die 21, Fig. 3, for finishing by a top die 22 for example in a fly press to produce a rear axle forging. In another example for producing a cam or tappet members a rod headed as above has the head flattened laterally and a recess forged in the end thereof. Hot milling is then used to produce grooves in the head obtaining a desired result without complicated forging means. In a further example, similar to Fig. 1, two kinds of steel 34, 35 are flash welded at 36, Fig. 7, the blank is then held by tongs whilst supported on rollers for removal of the flash by hot milling. The rod is then upset as in the first example, unwanted metal removed by further hot milling and the article is finished by further pressing in dies to the shape shown in Fig. 11 in which the line 44 indicates the weld between the two studs.
