Abstract: 1,185,978. Separable moulds and formers. TAIYO KOGYO CO. Ltd. 17 Jan., 1969 [19 Jan., 1968], No. 2773/69. Heading B5A. [Also in Division H1] Component parts of an object e.g. a barrelshaped mould or former, are held together by causing an electric current to flow momentarily through a conductor adjacent the component parts, of which at least their lines of mutual contact are of ferromagnetic material, thereby causing the ferromagnetic portions to become magnetized and held together, and the parts are separated by causing an electric current to flow momentarily through the conductor in the opposite direction to demagnetize the parts. The individual mould parts may be mounted in an insulated manner on a central shaft e.g. of copper through which the current is passed. As described, an article may be made by winding string around the periphery of such a former and painting it with plastics resin, the former being disassembled after hardening of the resin.

Filed: 1933-01-28
Abstract: 402,616. Hydraulic transmission of power. FOTTINGER, H., 65, Berlinerstrasse, Wilmersdorf, Berlin, KRUCKENBERG, F., and STEDEFELD, C., 16B, Ellernstrasse, Hanover, both in Germany. Jan. 28, 1933, No. 2779. Convention date, Jan. 29, 1932. [Class 69 (ii).] In vehicle transmission gear embodying a separate F÷ttinger gear for each direction of travel, and in which the primary wheels of the gears rotate in opposite directions, the axes of the gears are perpendicular both to the axis of the prime mover and the longitudinal axis of the vehicle. In the construction shown in Figs. 1 and 2 the motor shaft 11 drives a shaft 16 through spur gearing 12, 13 the shaft 16 driving hollow shafts 19, 20 loose on each axle 17, 18 in opposite directions through bevel gears 14, 21, 22. The primary wheels 23, 24 of two F÷ttinger couplings or transformers are fixed to the shafts 19, 20 and are thus driven in opposite directions. The secondary wheels 25, 26 of the transformers are fixed on the axle 17 or 18 so that the axles are driven in one direction or the other according to which transformer is in use. In the construction shown in Figs. 7 and 8 the F÷ttinger gears 23, 24 drive a shaft 49 which drives the axle 17 through spur gearing 50, 51. The F÷ttinger gears and toothed gearing are mounted in a casing 52 pivoted on the axle 17 and connected to the spring-supported vehicle frame 34 by arms 57, 58 and springs. The following modifications are described-(1) In Fig. 3 (not shown) the two F÷ttinger gears on one axle are of different size to those on the other axle, the large gears on one axle being used for large tractive efforts and the smaller gears on the other axle being used for low tractive effort and higher speeds. Since only one of the four gears is in use at a time the two axles may be mechanically coupled together by coupling rods. (2) In Fig. 4 (not shown) the F÷ttinger gears are mounted on the spring-supported frame and drive large hollow shafts which surround the axles and are connected to the driving wheels by flexible couplings so as to allow of movement between the hollow shafts and the axles. The couplings may be those described in Specification 290,067, [Class 79 (ii), Motor vehicles, Driving &c.]. (3) In Fig. 6 (not shown) the two F÷ttinger gears are mounted on the spring- supported frame between two axles which are driven by coupling rods. (4) In an arrangement particularly for narrow gauge vehicles each axle carries one F÷ttinger gear, so that the gears for forward and backward travel are mounted on different axles.

Patent GB-1469162-A (GB)
Title: Tyrebuilding apparatus
IPC: B29D30/20
Filed: 1974-01-23
Abstract: 1469162 Manufacturing breaker-tread assemblies for tyres UNIROYAL Inc 23 Jan 1974 [5 Feb 1973] 03070/74 Heading B7C A radially expansible and contractible drum for building a breaker-tread assembly, comprises a plurality of arcuate segments 166, each segment having a radially inwardly extending leg 168 carrying a respective cam follower 172, all the cam followers engaging a single continuous spiral cam groove 170 provided in a disc 114 rotatable, relative to the segments, to effect simultaneous movement of the segments to be a desired drum diameter. The segments, are carried by a disc 162, keyed to a rotatable shaft 150. The drum is rotated by a reversible motor 136, through gears 140, 142, 174, 176, when clutches 138, 180 are engaged. Disengagement of both clutches enables the drum to be freely rotated at station C-C where tread stock is applied to the drum, and disengagement of clutch 180 and engagement of brake 182 causes, via shaft 144, and gears 146, 158, rotation of the disc 114 relative to the disc 162, with radial movement of the segments. Adjustable actuators (72, 75) (Fig. 5, not shown) attached to one segment operate a switch (76) when the segments are in the fully expanded and fully contracted positions. A further switch 77 is actuated when the segments are at a desired radial position. As motor 136 rotates the shaft 144 a pulse generator 378 produces pulses which are effectively subtracted from a reference pulse signal, As the quantity of pulses in the reference pulse signal approaches zero the motor slows down. The drum shaft 150 is journalled in a frame 286 which is movable together with, and relative to, a second frame 285 along guide rods 273, 290 by means of ram 277 and a belt and ram mechanism 272, so that the drum can be moved to stations A-A, B-B, C-C at which breaker plies and a tread are applied and station D-D at which the assembly is removed by a transfer ring 272. Each segment includes a magnetic strip 100, and spot magnets are located in radially outer surfaces of the segments. The magnets and magnetic strips attract metal cord breaker piles. The movement of the drum between positions A-A to D-D, its rotation by drive motor 136, its free rotation, and its expansion and contraction is controlled by control means including the switches 76, 77 and switches 287 (Fig. 2).

Abstract: 676,322. Semi-conductor amplifiers. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. Feb. 7,1950 [Feb. 18, 1949], No. 3134/50. Class 40 (iv). A point contact assembly suitable for a transistor arrangement comprises two resilient contact elements 1 and 2, secured in electrode carriers 14 and 15, and which engage the surface of an element of material 6, which may be a semi-conductor. The element 6 is adjustable so that the surface may be raised, causing the tips of the electrodes to engage the surface at points slightly spaced from each other. The spacing may thus be adjusted to that required between the emitter and collector electrodes of a transistor. To facilitate adjustment and the selection of a suitable point on the semi-conductor surface, the carriers 14, 15 of the point contact electrodes and the electrode 7 which is bonded to the semi-conductor may be slidable and rotatable in their respective mountings. A housing is provided which comprises a window 11 for use when assembling the device.

Title: Improvements in pie moulding or like machines
Inventor: STOCKHOLM KENNETH RONALD
IPC: A21C11/00
Filed: 1951-02-09
Abstract: 683,664. Pie-moulding machines. PEERLESS & ERICSSON, Ltd. Feb. 9, 1951, No. 3160/51. Class 87 (ii). Relates to pie moulding machines in which two co-axial reciprocating tools are operated in succession to mould a pie and trim the edge of the moulded article, and comprises a machine with a reciprocating rod 3 carrying the moulding tool 9 and coupled to a crankshaft 4 by a connecting rod 6, the cutting tool 13 being slidable on the moulding tool and pressed upwards by a spring 14, and a presser member, slidable on the rod 3, for pressing the tool*13 downwards on the tool 9 after the moulding of the pie casing and characterised in that it is normally in stationary relationship with the reciprocating rod 3, and a cam or cams 7 acting on the presser member during a part only of the revolution of the crankshaft 4 to move the tool 13 quickly on its cutting stroke. The presser member comprises two rods 8 having rollers 8a at the top to engage the cams and connected at the bottom by a cross piece 16 engaged over the rod 3, with a pin 17 slidable in slots 18 therein and anchoring a tension spring 19 so that the cross piece 16 is normally urged upwards, and connected near the top by another cross piece 25 which is normally held against a shoulder 26 on the rod 3 by the action of the spring 19. To allow for different thicknesses of pie tins the bottom cross piece 16 is resiliently connected to the rods 8 by the interposition of Springs 24. As the rod 3 descends it carries down the moulding tool 9, the cutting tool 13 and the presser member, the last by the shoulder 26 bearing on the cross piece 25. The periphery of each cam 7 lies outside the axis of the crankshaft 4 and the cams therefore only bear on the rollers 8a when the pressing member is required to move down the tool 13 for the actual cutting stroke, this condition being shown in Fig. 3 where the rod 3 and moulding tool are starting to rise and the cams 7 are starting to depress the rods 8. This short time of operation of the cams 7 gives a quick cutting stroke, but each cam has a concentric portion 7a to hold the tool 13 depressed on the pie tin for a short time and prevent the tool 9 from lifting the pie tin by suction.

[Also in Group XIII] A gilled tube comprises a tube with a spirally wound gill element thereon with a flange adjacent the tube which is attached to the tube by spot welding. Steel strip 14 is fed through rollers 15, 16, which form it into strip 11 of L- shaped cross-section, on to and by a rotated tube 10. The tube 10 is engaged on its underside by roller electrodes 19, 20 and on its upper side by a roller electrode 21 bearing on the flange of the gill strip 11. The rollers are urged against the tube 10 by a pneumatic cylinder means 36 mounted on a vertically slidable frame 27 carrying the rollers 19, 20, the piston of the cylinder being connected to the upper roller 21, vertically slidable relative to the frame 27. The roller electrode supporting means and the strip forming means is moved axially of the tube 10, e.g. by a feed-screw, as the tube is rotated, although transformers may be carried on a separate fixed unit. The roller electrodes may be watercooled. The roller electrodes 19, 20 are connected to one side of a transformer secondary winding 31 and the roller 21 to the other, a timing device in the circuit produces an interruption of current so that the gill is stitchwelded on to the tube. A roller electrode 42, in the form of one or more rollers, connected to one side of the secondary winding of a heating transformer 32, the other side of which is connected to the rollers 19, 20, heats the strip to facilitate forming and winding.

Abstract: 1,064,543. Multiplex pulse code signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Jan. 12, 1965 [Jan. 24, 1964], No. 3230/64. Addition to 960,388. Heading H4L. The synchronizing arrangement for a time divison multiplex pulse code signalling system shown in Fig. 2 of the parent Specification is modified, Fig. 1 (not shown), by the omission of gate G9, the toggle M which controls the delay device DL being returned instead by a signal derived from the channel 24 position of counter C2. The delay device DL is in the form of an integrating circuit. In this way although, due to the delay device, hunting for the correct synchronizing signal is not initiated in response to a single false synchronizing signal occurring during normal operation, if, during the hunting operation, the equipment locks on to a spurious signal formed by a random combination in the information channels, the toggle M is not reset and hunting will continue until the correct synchronizing signal is found. This reduces the time required to re-establish synchronism. Fig. 3 of the parent Specification is similarly modified, Fig. 2 (not shown).
