Title: Hydraulic telemotor system
IPC: F15B7/10
Filed: 1964-05-26
Abstract: 1,063,161. Telemotor systems. J. MERCIER. May 26, 1964, No. 21777/64. Heading F1P. In a telemotor system, Fig. 1 (not shown) comprising a transmitter piston (14) slidable in a cylinder (11) and a receiver piston (45) slidable in a cylinder (42) wherein the transmitter piston (14) is moved to effect a corresponding movement of the receiver piston (45) and liquid in the system is automatically maintained constant by a pressure accumulator (31), a two-position selector valve (22) is manually operated, when due e. g. to leakage past the pistons, the position of the receiver piston requires re-setting with respect to the transmitter piston. To reset the piston (45), piston (14) is moved to its extreme left position by control means (16), so that piston (45) is moved to the right by the column of liquid in chambers (A1, B1) and lines (19, 48). Thereupon the valve (22) is operated to connect the column of liquid to the pressure accumulator (31) thereby moving the piston (45) to its extreme right position. Liquid may be introduced to the system/through a normally closed valve (36).

Abstract: 1470072 Shoots SVENSKAFLAKTFABRIKEN AB 16 May 1974 [21 May 1973] 21787/74 Heading B8S A dumping structure, for refuse or laundry, includes a shoot 2 directed obliquely downwards and opening into a substantially vertical dumping shaft 1, being fitted with a gate 7, coinciding in shape with the inner wall of the shaft 1, pivoted at its upper margin about a substantially horizontal axis 8 substantially closing the shoot outlet in the rest position and capable of swinging into the dumping shaft 1 under the influence of a bag of dumped goods 5. The upper margin of the gate 7 overlaps on the outside of the shaft 1 the adjacent edge of the opening into the shaft 1 and the lower margin of the gate 7 overlaps on the inside of the shaft 1 the adjacent edge of the opening into the shaft. As shown the gate 7 is held locked in the closed position by an electromagnetically operated pawl 12 until disengaged by pressing a button 13. Access to the shoot 2 is through a door 4. The shoot doors 2 are generally interlocked electromagnetically to permit only one door 2 to be opened at a time to prevent two or more bags of goods 5 being dumped simultaneously and possibly causing collisions and jamming in the shaft 1.

Title: Housings for enclosed length measuring devices
IPC: G01B3/00
Filed: 1978-05-24
Abstract: This two-part housing (1) provided for encapsulated length-measuring instruments and in which a scanning unit (6) under spring tension is guided along a material measure (5), consists of a first housing part (1a) which is mounted on a machine component (10), for example by means of mounting screws (9) acting only on said housing part, and of a second housing part (1b) which is mounted on the first housing part (1a), for example by means of screw plugs (2). The housing parts have projections (1a', 1b') and depressions (1a'', 1b'') which interlock at their joint and which keep the two housing parts (1a, 1b) joined to one another in a self-closed fashion even after removal of the screw plugs (2), with the result that for the purpose of cleaning the device the second housing part (1b) can be removed from the first part (1a) by only one person and in so doing the scanning unit (6) under spring tension can be prevented from jumping out. A sealing cord (3) is provided between the two housing parts (1a, 1b) in the region of the self-closed joint. <IMAGE>

Abstract: 915,528. Two-part couplings; cable terminals. AMP Inc. June 30, 1959 [June 30, 1958], No. 22399/59. Class 38 (1). A connector comprises a coupling portion integral with a ferrule 2 which is fastened to a sleeve 8 by inserting a wall 10 of the sleeve between portions 4, 6 of the ferrule and then expanding the portion 6 to a conical shape by means of a mandrel. An insulated cable 14 has its end stripped and secured in the ferrule by crimping and the portion 4 is crimped so that the cable insulation is gripped. In Fig. 4, a fluid-tight seal is formed between the sleeve 8 and a passageway in a block 16. Fig. 5 shows a connector 20 comprising a coupling-pin 24 engaged in a socket member 42. Between the pin and the ferrule 2 is a longitudinally split sleeve 26 having projections 28 ; the sleeve is held between collars 30, 32, the collar 30 being removable. The collar having been removed, the connector is pushed into a passageway in a block 22 until the projections 28 snap behind a shoulder in the passageway and the collar 32 abuts a second shoulder. The collar 30 is then slipped over the end of the pin 24 and is pushed along the pin until it abuts the projections 28. The socket 42 forms part of a second connector 38 mounted in a block 40.

Title: A new or improved bobbin feeding mechanism for spooling machines
IPC: B65H67/06
Filed: 1952-09-06
Abstract: 733,439. Supplying bobbins to machines. AYRTON & CO., Ltd., W., and TAYLOR, J. D. W. Sept. 7, 1953 [Sept. 6, 1952], No. 22447/52. Class 120(3). [Also in Group XXX] Bobbin feeding mechanism comprises a hopper 27, a tundish-shaped rotatable orienting member 37, a collect - ing shoot 36, and a swingable holder 62 in which the oriented bobbin is adapted to be swung away for delivery to the next machine. As shown, the hopper 27 is subdivided to form a number of outlets, of which one is shown, the outlet having the member 37 rotated from motor-driven shaft 32 so as to deliver the bobbin one by one into shoot 36, the bottom bobbin resting in holder 62. Whenever the spooling machine to be fed depresses rod 55, lever 44 rotates about pivot 53 and thus engages clutch 43 so that continuously-rotating motor-driven shaft 32 drives cam 52 through belt 50 whilst simultaneously withdrawing finger 44A to release said cam 52. The rotation of cam 52 displaces rack rod 68 by means of follower 72 and so causes oscillation of shaft 56 and thus of holder 62. The cam is such that the holder swings once to the right and then once to the left so as to feed the bobbins to the shoots 76 of two separate machines. Escapement device 82 is contacted at each oscillation so that it swings beneath the shoot 36 to support the bobbins remaining in said shoot at the same time as a bobbin is in process of being fed to shoot 76. The holder 62 has removable liner 67 to allow for bobbins of differing diameters.

[Classes 22 and 87 (ii)] In the production of concrete articles having a facing 6 of fine concrete and formed by pouring concrete in two layers 6, 7 on a mould face 3 bearing a design, the mould face 3, before the concrete is poured thereon, is cleaned with a quickly evaporating grease solvent, such as methylated spirit, to facilitate and ensure the intimate contact of the concrete with the most delicate parts of the design. The mould face 3 may be made of glass, metal, wood or rubber, and may have a polished, matt, or stippled finish. The design may be in relief, in intaglio, or in both, and may be made by cutting, grinding, sandblasting, etching or in any other manner. The second layer of concrete 7 may be coarser than the layer 6. To produce coloured articles the mould face is covered at the desired parts before pouring on the concrete, with a flake, e.g. small pieces of metal foil, or with dry and finely divided powder or dust, e.g. metallic dust such as gold, silver, bronze or aluminium, dyes, or dyed dust, the mould being afterwards shaken to diffuse the materials in the layer 6 ; alternatively, the mould face may be painted and the concrete poured thereon. The articles may be reinforced by fibrous or fabric materials or metal within the concrete. The finished articles may be coated with a vegetable oil, the surplus of which is afterwards removed, to remove or prevent the formation of powder on the surface.
