Title: Improvements in or relating to apparatus for tempering springs in a spring coiling machine
IPC: C21D9/62
Filed: 1968-05-17
Abstract: 1,211,585. Making springs; coiling. INDUSTRIFJADRAR A.B. 17 May, 1968 [17 May, 1967], No. 23662/68. Headings B3A and B3E. An apparatus for bending or coiling springs in which the tools IV, V and VI for bending or coiling a wire about a mandrel VII have means for passing an electric current through the spring for tempering is characterized in that the current intensity is regulated in relation to the speed of advancing the spring wire by control means comprising a tachometer generator 5 producing a control voltage connected by a voltage divider 6 to resistors 7, 8 and to a unit including a selectable number of diodes 9 in shunt and said unit converting the linear control voltage of the generator so that the voltage actuating the heating current control from being being linear in respect of the rotary speed of the wire feed rolls II and the generator becomes a logarithmic function of said feed and controls the heating current from a rectifier 3 so that heating varies relative to the speed of advance of the wire. The feed rolls are connected to the rectifier 3 the pole 4 of which is connected to the tool V to heat the wire. A device 10 ensures that a minimum current passes through the wire during short standstill periods when a coiled spring is being severed to prevent too great a fall in spring temperature. A wire guide III is provided with a heating coil 11 adjacent the mandrel and a cold air cooling nozzle VIII following the feed rolls. Oscilloscope terminals 12 and 14 are provided for checking the tempering operation.

Title: Improvements in or relating to Electric Circuit Arrangements for the Production of Current Pulses
IPC: H03K17/64
Filed: 1967-05-24
Abstract: 1,153,257. Transistor switching circuits; circuits employing magnetic storage elements. SIEMENS A.G. 24 May, 1967 [25 May, 1966], No. 24105/67. Headings H3B and H3T. The voltage supply to a constant current device feeding a load comprises a capacitor arranged to provide a higher voltage while the current is building up and a diode connected across the capacitor and to a voltage source to thereafter supply a lower voltage. The circuit shown feeds a pulse to a core storage line, the far end of which is short circuited so that when the reflected pulse returns to terminating resistor 7 the line appears as a short circuit (Fig. 1, not shown). The pulse begins when a constant current transistor T1 is rendered conducting, the initial supply voltage being equal to that of a higher voltage of a supply U2 due to the charge on C but as this discharges the effective supply voltage drops to U1. Energy loss in T1 is thereby reduced. The charging resistor R2 may be replaced by a transistor S rendered conducting when T1 is off. The capacitor C may alternatively be charged from U1 via a transformer (Fig. 4, not shown).

Title: Improvements in or relating to change speed gear
IPC: F16H15/38
Filed: 1923-09-28
Abstract: 205,479. Waltefaugle, G. A., and Jarrand, A. A. J. Oct. 11, 1922, [Convention date]. Variable-speed and reversing gearing of the kind comprising elements 1, 6, Fig. 3, having annular gear tracks of curved contour connected by rollers 3 which are tilted to vary the speed, is modified in that the said tilting is done by the power of the engine when the rollers are turned about a diameter through the points of gear contact, like the front wheel of a bicycle. The rollers 3 are supported in frames 12, Fig. 4, which are eccentrically supported at their ends 22 &c. in a carrier ring 7 so that the required initial deflection of the rollers with respect to thin paths on the discs is effected by moving in unison the inner ends of arms 33 which engage a central sliding boss 36. In the arrangement shown, the disc 1 is secured to a driving-shaft 2, the carrier 7 is fixed, and the disc 6 transmits to the stub shaft 58 of an epicyclic reversing-gear. The boss 36 is moved by a centrifugal governor 45 acting against a spring 47, or is otherwise controlled by way of a movable cap 49 and a cable 56. Frictional engaging pressure is maintained by balls 106, Fig. 9, which become wedged between cams on the back of the disc 6 and a spring-pressed boss on the shaft 58. Alternatively the carrier ring 7 may be adapted to rotate, and the gearing may be used differentially to drive two shafts. Or it may be adapted to be actuated say by a windmill and by an auxiliary motor. The reversing-gear described comprises a sun gear 66 on the shaft 58 and an internal gear 62 secured to the tail shaft 65. Planet gears 67 are carried by a drum 61 which is adapted to be engaged by a cone clutch 84 for forward driving, and by a band brake 70 for reversed driving. The clutch cone 84 slides on gear drum 62 and is kept from being thrust too far by disengaging spring 85 by hooks j engaging projections k on the drum. The brake 70 is controlled by a spindle 73, Fig. 10, with threads of opposite hand connected to the clutch-operating lever 91 by a rod 83. The reversing-gear is thus operated by way of a single rod 82. The spindle 73 carries a shaped lever 74, Fig. 11, and when the brake is on, the lever 74 is canted so that a spring-pulled roller 76 rides out upon it to effect a lock. This lever may extend in the opposite direction to lock the clutch drive.

Filed: 1927-09-14
Abstract: 291,655. Rushton, J. L., and Farnworth, W. Sept. 14, 1927. Mules.-In an arrangement for bringing the fallers into position during backing-off in which a closed system of chains is used tightened by a jockey pulley, the jockey pulley is controlled by a weight so mounted that part of it is operative to provide 'the requisite tension whilst the system is stationary or in steady movement, but that the whole becomes operative to resist any substantial movement of the chains due to the imposition of heavy loads upon them. The faller shaft 3 is carried in a frame 1 and has secured to it a sector 5 to which is attached a chain 9 secured to the pulley 10. A further chain 12 connects the pulley 10 to the backing-off scroll on the tin-roller shaft 7. A second chain 15 is attached to the shaft 7 to wind in the opposite direction and is secured to a pulley 16 on a shaft 17. A pulley 18 on this shaft has connected to it a chain 19 which passes round guide pulleys 20, 21 and under a jockey pulley 22 up to a sector 6 on the faller shaft. A cylindrical weight 23 sliding on a guide rod 29 is attached by a lug 25 to the jockey pulley 22 in such a manner that when the chain system is slack is rests wholly on a bracket 27, but when the chains move normally it is held in a tilted position but still resting partially on the bracket. Any sudden load raises the weight wholly from the bracket. The sector 6 comprises a pivoted member 35 adjusted by a screw 40 engaging an extension 37.
