Title: Improvements in and relating to signal devices for use on road vehicles and the like
IPC: B60Q1/34
Filed: 1939-09-07
Abstract: 532,761. Road-traffic signals for vehicles. SMART, E. F. Sept. 7, 1939, No. 25284. [Class 118 (ii)] Relates to a traffic-signal, of the kind described in Specification 263,896,[ Class 118 (ii)], in which signal arms are pivoted to the end of a member that slides into a horizontal casing, movement of the member to its outward position causing the arms to swing to a predetermined angular position. According to the invention, a casing containing an electric lamp is attached to the outer end of the sliding member, and the signal arms are housed in this casing when the sliding member is in its inward or non-signalling position. Two sliding members 1, 2, Fig. 1, are housed in a tubular casing 3 and are moved to and from the signalling position by handles 4, 5, respectively, which project through the casing. Each sliding member comprises a flat compartment 8, Fig. 3, in which the pivoted signal arms 9, 10 are housed, the casing being open at its lower side to allow the arms to emerge. The lamp casing comprises an open frame 11 that fits on to lugs 8a on the front edge of the compartment 8, and a second frame 16 that fits over the frame 11, translucent sheets 11d being held between the two frames. An opening 16a allows the light of a lamp 12 in the casing to illuminate the arms 9, 10. Saw cuts 8e are formed near the front end of the casing 8 to allow the member 11 to snap off and prevent further damage in the event of a collision. The lamp 12 is connected by leads to contacts 14, Fig. 1, which make contact with battery contacts 15 when the sliding member is in the signalling position. A second pair of contacts may be included to illuminate a sign, representing the signal, which may be placed at the back of the vehicle. The sliding members 1, 2 may be housed in separate tubular casings and may be operated by remote-control devices.

Title: A magnetostrictive and electromechanical transducer device
IPC: H03B5/00
Filed: 1951-10-30
Abstract: 709,528. Piezo-electric and magneto-strictive instruments. CLEVITE CORPORATION. Oct. 30, 1951 [Jan, 24 1951], No. 25332/51. Class 40 (4) [Also in Groups XXXVI, XXXVIII and XL (c)]  A piezo-electric element and a magnetostrictive element are secured together so that either element may be used to exert a mechanical control over the other. The mechanical strain in the controlled element controls the electrical characteristic of a circuit associated with the element. Both elements may be electrically controlled to produce mechanical vibration in the device. As shown in Fig. 1, a plate 10 is of Rochelle salt or of barium titanate is secured between a nickel plate 11 and an electrode 12. With the switches 17, 22 as shown, signals from a source 16 control the piezo-electric element 10. The magnetostrictive element 11 is driven by the piezoelectric element 10 and produces flux changes in a coil 21 which feeds a signal reproducer 25. A D.C. bias is supplied from a source 23 and may be cut out by a switch 30. By means of the switches 17, 22 either element may be connected to a source of signals and the other element to a signal reproducer. Both elements may be driven by signals simultanously to vibrate the device either as an expander or as a bender. The magneto-strictive element may be biased electromagnetically as shown or by a permanent magnet 32, Fig. 2 or by residual magnetism. An element of barium titanate is prepolarized in known manner by a high D.C. voltage. The electrode 12 may consist of a second magneto-strictive element. Two piezo-electric elements 10 may be combined with three magneto-strictive elements as shown in Fig. 4., The elements of any of these devices may be formed as closed loops. If a small gap 44 is left in the magnetostrictive element 41, the cylindrical device shown in Fig. 5 may be used as a recording or reproducing head (see Group XXXVIII) or as a device for measuring magnetic fields (see Group XXVI). The magneto-strictive elements 11 are used to couple coils 75, 76 in the anode circuit and the grid circuit of an oscillator valve 70, Fig. 11. The coupling is controlled by the bias potential applied from a source 77 to the piezo-electric element 10. Fig. 12 shows the device used as a variable coupling between an A.C. source 80 and a voltmeter 85. The coupling is controlled by an adjustable source 82 of D.C. bias and a biasing coil 83.' The elements of the device may be cemented together. Nickel may be electroplated on some piezo-electric elements and may be soldered or fired to barium titanate. The device may be used instead of quartz to control the frequency of oscillatory circuits (see Group XL (c)).

Abstract: 457,561. Boot - making machines. MILLMAN, C. H., and DOVE, G. H., Standard Works, Evington Valley Road, Leicester. Sept. 13, 1935, No. 25430. [Class 17 (i)] Uppers, machines for.-In machines for forming outwardly turned flanges on the uppers of boots and shoes, the upper is clamped between two mould parts by the operation of a treadle or other manually operated means, whereupon an electrically driven thruster is brought into operation to move a wiper past the margin of the clamped upper to form the outwardly turned flange. A fixed inner mould b co-operates with outer mould members c pivoted together and linked to a lever h, cam members closing the members c on the upper or the inner mould as the lever h is swung by, toggle links i resiliently connected to a treadle e. A wiper m backed by a cam q is secured to the piston rod of an electrically-driven thruster n comprising a pump forcing oil beneath the piston, a small hole in which allows return when the pump is stopped. When the upper has been clamped by partial depression of the treadle, full depression actuates a switch o to start the pump. The wiper m forces the upper margin into a recess r in the outer moulds, and travels beyond the moulds so that these can separate to release the upper when the treadle is released.

Title: Improvements in yarn twisting and winding apparatus
IPC: D01H1/00
Filed: 1945-10-01
Abstract: 600,049. Twisting and winding yarn. MARQUART, A. S. Oct. 1, 1945, No. 25447. [Class 120(ii)] Apparatus for twisting and winding yarn from roving comprises a rotatable cage enclosing a bobbin &c. co-axial with the cage and a traversing mechanism longitudinally arranged in the cage, in association with a hollow spindle on the cage which supports a pair of rollers mounted to turn on transverse axes and driven by gearing as the spindle rotates, the arrangement being such that roving fed in the direction of the axis of the rotating spindle and cage passes directly into and through the nip of a pair of rollers which feed and twist the roving into yarn while delivering it through the hollow spindle to the longitudinal traversing and winding mechanism in the cage. The flyer or cage comprising end plates 11, 12 and bolts 10 is driven by a chain 15 taking on to a sprocket sleeve - 14. Freely mounted on the sleeve 14 is another sprocket sleeve 16 driven by a chain 17, the sleeves being supported in a bracket 18. The sleeve 14 is formed at its end as a disc 19 with lugs 20 supporting spindles 21 carrying gears 23, 24, which through gears 25 drive a pair of rubbercovered feed and twist rollers 26. The gears 23, which extend through slots in the disc 19, are driven from teeth 27 on the sleeve 16. The driving chains 15, 17 also drive members 40, 41 of a differential gear in reverse directions so that if the chains were moving at the same speed the middle member 38 of the differential would maintain the shaft 37 stationary. Since, however, the speed of chains 15, 17 is different, the shaft 37 drives the feed rollers 28 at the same speed as the rollers 26. If a reverse twist is required the chains 15, 17 are driven in reverse direction and the gear 33 is brought into mesh with the gear 35 for driving the rollers 28. The traverse is effected by a slide member 46 reciprocated by a double-screw 54 rotated by gears 48, 49, 53, the gear 48 being carried by a bush 47 to which is pegged the bobbin 8 dragged round by the pull of the yarn. The rod 9 is withdrawn to the left for doffing. If it is desired to effect drawing the rollers 28 may be rotated at a faster surface speed than the feed rollers 29 and the rollers 26 than the rollers 28. In a modification, power shafts 64, 65 drive friction drums 72, 73 at different surface speeds, these drums, in turn driving friction rollers 74, 75 which replace the sprockets 14, 16. The differential 78 driven by the chains 70, 71, drives the feed rollers 76. The twisting devices are carried by spring-urged brackets 61 pivoting on a spindle 62 so that each twisting and rewinding device in a frame may be drawn back from the driving rollers 72, 73. In a further modification, separate electric motors may be used for driving the cage and feed rollers.

Title: Method of and apparatus for converting molten metals into solidified products
IPC: B22D23/00
Filed: 1977-06-20
Abstract: From a casting apparatus, a metal melt flows to a cooled rotating drum (9) and solidifies to give a thin metal strip (10) which is stripped off and divided in a flying shear (12) into sections which are laid one upon the other on a table (20) by means of supports (14). After each section is laid down, the workpiece to be produced is moved backwards and forwards and pressed between a pair (22, 23) of rollers, whereupon the finished workpiece is pushed off the table (20) at the side. This makes it possible to produce in any thickness workpieces which were hitherto produced by laying one upon the other individual strips produced in separate casting apparatuses, and a considerable reduction in the costs and space requirement is thereby achieved. <IMAGE>
