Title: Improvements in or relating to apparatus for cutting-off plastic extrusion-moulded articles
IPC: B26D1/60
Filed: 1948-11-05
Abstract: 649,228. Cutting-off extruded lengths. GRACE, E. C., BEAK, T. W., and HALEY, D. Nov. 5, 1948, No. 28851. [Class 87 (ii)] A clay pipe or tube, or a hollow block or other article is extruded vertically downwards from a nozzle 12 and passes through temporarilystationary sleeves 32, 31 which form part of a vertically-rising-and-falling apparatus A, the pipe &c. coming to rest on a platform 18 which is mounted on a rod 19 vertically slidable in another platform 11 forming part of the apparatus. The apparatus A, which carries a manually-operable horizontally-sliding cutting wire 34, then descends under the weight of the pipe, and when the required length of pipe has been extruded the operator passes the wire through the pipe. This cutting operation results automatically in actuation of a trip-lever 38 to release a catch 36, which normally holds the platform 18 up, and the platform then drops on to a resilient buffer 26 on the platform 11, whereupon the cut-off piece is removed by hand. The platform 19 is counterweighted by a lever 21 carrying a weight 22, so as normally to be held in the raised position shown. The whole apparatus A also is counterweighted by means (not shown) connected by ropes, chains, &c. 15 to brackets 16 formed on a box-like member 17 integral with platform 11. Bearings 13 on the apparatus slide on pillars 14. The cutting wire 34 is stretched between the sides 41 of a cutting frame 27 slidable in a housing 28, the frame having a handle 35 for manual reciprocation. Cams 42, 42<SP>1</SP> on the sides 41 co-operate with a roller 40 carried by the upper end of the triplever 38. When the operator pulls the cutting frame towards him from the position shown in Fig. 2 the cam 42 actuates the trip-lever to release platform 11 which thereupon drops with the cut-off pipe. When the pipe has been removed the weight 22 raises the platform 11 again, its upward movement being limited by a stop 25. To cut off a second pipe length the operator pushes the cutting frame, whereupon the cam 42<SP>1</SP> operates the trip-lever. Springs 37, 39 urge the catch and lever clockwise and counter-clockwise respectively. According to the Provisional Specification the connection between the cutting frame and the trip-lever includes rack-and-pinion means.

Title: Gas turbine
IPC: F01D5/08
Filed: 1929-09-24
Abstract: 319,622. Kalßbek, V. Sept. 24, 1928, [Convention date]. Cooling parts; blades. - A gas turbine is cooled by passing through the wheels and blades a gaseous cooling medium, such as air or steam, at a pressure approximately equal to the pressure in the stage of the turbine to which it is admitted. The cooling medium passes through the blades into the working fluid stream, and gives up energy. Fig. 1 shows the application to a gas turbine, the first stage 1 of which has a double ring of rotor blades, the second and third stages 2, 3 having single rings. Cooling g medium is introduced by a pipe 12 and a channel K in the rotor boss to outwardly extending passages in the first rotor 1, from which it passes by channels in the blades into the surrounding chamber A and also into the blade spaces which are at the moment being fed by the first nozzle D. The cooling medium in the chamber A passes through slots s into the second nozzle E. The second rotor 2 and the third nozzle F are cooled in a similar manner by gas led in by a pipe 14. The last rotor 3 is cooled by an atmospheric air drawn through a grid v and forced outwards by centrifugal action in the rotor. The fixed blades 11 in the first stage are cooled by compressed air &c. introduced at 13. The casing members 9, 10 may be water-jacketed. The rotor blades are fixed by being clamped between adjacent sections of the rotor, and spacing pieces are: arranged in the channels in the rotor. The blades, Fig. 6, are formed of two parts 33, 36 connected together so as to leave a passage 35 between them. The cooling medium, which enters through a restricted opening 40, may escape into the stream of working-fluid at the periphery 37, or at one or both sides of the blade. One edge 39, Fig. 12, of the blade may be turned over so as to deflect the issuing air along the face of the blade. A shrouding ring is fixed to the tips 38.

Abstract: 364,099. Loud-speakers. COLASSI, W. L., 26, Burnham Court, Bayswater, London. Sept. 29, 1930, No. 29129. [Class 40 (iv).] Relates to a loudspeaker unit of the type having a reed formed with an armature portion and radiating supporting arms adapted to be tensioned, the armature portion being arranged in operative relation to a magnet polepiece or polepieces, with or without means for adjusting the relative position of the armature and magnet. According to the invention, a compression member is inserted between the mountings of the supporting arms so as to urge the mountings in the direction in which the tension is to be applied. The mountings may comprise pillars, parallel or inclined to one another, and wedging members in the form of rollers may be inserted between the magnets and pillars whereby on movement of the magnet the tension remains constant or is varied. Fig. 1 shows such a construction in which a is the reed, b the pillars mounted on the base c, d is the magnet and e the rollers. As shown, the pillars are recessed at f to limit the extreme movement of the rollers, the walls of the recesses being arranged parallel with the walls of the pillars so that adjustment of the magnet to. and from the reed will not affect the tension on the supporting arms. Fig. 4 shows a modification in which the tensioning means comprises a bar g, one end of which is hollowed at h to seat against one of the pillars whilst the other end is drilled at j to receive the reduced end k of a threaded pin m. The thread of the pin m engages a threaded hole in a member n which is shaped to seat firmly against the other pillar, rotation of the pin m increasing or decreasing the distance between the shaped ends. Each of these ends may be provided with a lug p adapted to pass through apertures in the radiating arms so that the pillars are engaged by the device both above and below the reed. The bar g is provided with an aperture q for the passage of the driving rod connecting the reed to the diaphragm.

Abstract: 922,334. Releasing articles from shoots. ADMOS Inc. Aug. 14, 1961 [Aug. 22, 1960], No. 29212/61. Class 78 (1). Articles are released from shoot 10 one by one by gate 20. Gate 20 is carried resiliently by pivot 24 carried by links 26 pivoted at 30. Pivot 30 is secured to arms 32. Arms 32 are connected to pull member 39 by means of pin 48 working in slots therein, member 39 being operated by the piston of solenoid 36. In Fig. 2, the article is sliding down towards gate 20, and in Fig. 3, a moment later, the article 14 is shown having been resiliently arrested by gate 20, the article engaging the rollers 70 carried by the gate, and the gate abutting stop 62 carried by arms 32 and being locked by the interaction of pin 48 and its slots. Operation of gate 20.-Solenoid 36 is momentarily operated to pull member 39 to the left. This through the action of pin 48 moves arms 32 clockwise about pivot 30 and thereby withdraws gate 20 beneath the article 14 (from the position of Fig. 3 to that of Fig. 4), to permit the article to move downwards to the right. In this position the springiness of gate 20 causes it to engage the underneath of the article as it passes, so that when the article has passed, the arm 20 rises under its spring back to position of Fig. 2 to check the next article. This it performs because the solenoid has been operated only temporarily so that gate 20 and member 39 is free to be moved under the operation of springs 74 back into their original position as shown in Fig. 2. Thus, with each operation of solenoid 36 one article is released.
