Title: Improvements in machines for making hollow bodies by spinning metallic sheet material
IPC: B21D22/16
Filed: 1961-05-10
Abstract: 919,927. Spinning. KOEHLE, K., and HUMMEL, H., [trading as BOHNER & KOEHLE]. May 10, 1961 [May 11, 1960], No. 16921/61. Class 83 (4). A machine for producing conical hollow bodies from metallic sheet material by spinning comprises an annular work-holder 12 on which the sheet 25 is clamped near its edges by plates 23 over a rotatable forming tool 29 and means 8 for rotating the work and holder 12 at the same speed and in the same direction as the driving shaft 31 of the tool 29 whilst the sheet is pressed against the forming tool by a roller-type pressure tool 35 moved by mechanical or hydraulic means parallel to the surface of the former 29. The holder 12 is supported by four guide rods 10 slidably carried by the member 8 to cause it to rotate with the pressure tool 35. The heads 16 of the rods 10 may have their flat inner faces in contact with the clamped edges of the work to provide additional driving torque to the work. The tip 35 of the former 29 is removable and may be replaced by rounded or other shapes. The work-clamping plates 23 are spaced equidistantly around the work edges. In a modified form, Fig. 3, the work-holder 56 is driven by the forming-tool shaft 50 by gears 68, 70, a shaft 64 and a pinion 62 meshing with a toothed ring 60 formed on the annular work-holder 56 which is itself supported by rollers 54 engaged by a groove 57 formed on its periphery. Guide rods 42 extend at their upper ends through a ring 52 which also provides a bearing for the pinion driving shaft 64, the lower end of which is splined and slides through the gear-wheel 70 as the work-holder is moved downwards during the movement of the work under the action of the pressure tool, as previously described. The work-holder 56 may be carried by anti-friction bearings in the ring 52 instead of by the rollers 54 on the extended ends of the guide rods 42.

Abstract: 1,032,066. Commutation arrangements for dynamo - electric machines. KABUSHIKI KAISHA HITACHI SEISAKUSHO. April 30, 1963, No. 16985/63. Heading H2A. In a commutatorless electric motor an inductive, high frequency, pick-off device supplies triggering signals to the transistors which control the sequential supply of power to the armature winding. A high frequency A.C. voltage is induced in secondary winding L2 of the rotary transformer from primary winding L1 which is supplied from oscillator O. This A.C. is detected by either of coils La or Lb, by inductive coupling with rotating coil L3, and is used, after rectification, to cause transistors Ta, Tb to conduct, thus connecting power supply E to each half L4, L5 of the armature winding in sequence and thus cause the permanent magnet rotor R to rotate. In modifications the rotating coil may be replaced by a shaped magnetic member which induces a voltage in the pick-up coils or an electrostatic system may be used. In order to eliminate the spurious signals induced in the second pick-up coil a high frequency signal from the oscillator is introduced in the common lead from the pick-up coils both of which simultaneously pick up signals which are 180 degrees out of phase. If all voltages are made equal then the oscillator signal will cancel each of the pick-up coil signals in turn.

Title: Improvements in bonnet constructions for motor vehicles
IPC: E05D1/04
Filed: 1937-06-21
Abstract: 502,628. Hinges. HALL, W. J. June 21, 1937, No. 17267. Convention date, June 20, 1936. [Class 65 (ii)] [Also in Group XXXI] Motor-vehicle bonnet flaps are connected by a spirally curved hinge or hinges to the sides of a channel-shaped supporting member, the flaps being extended above the hinges so that in the central longitudinal line of the vehicle their edges are separated by only a narrow gap, underneath which the channel serves for disposal of rain water. As shown in Fig. 6, each bonnet flap 10, 12, is doubled back and bent downwardly to form vertical flanges 36 to which are welded or riveted curled hinge members 32 coiled round correspondingly formed fixed hinge members 24 attached to or formed integrally with the sides of a channel member 18 extending between the radiator and cowl of the vehicle. The doubled back portions of the flaps preferably bear on the outer hinge portions 32, the edges 39 being separated by a gap allowing clearance for pivotal movements, which are limited by the hinge construction or by abutment of the edges 39 against the walls 20 of the channel. To increase the range of pivotal movement, the walls &c. may be inclined to form an acute angle with the base of the channel. In the form shown in Fig. 8, the flap extensions 60 are depressed to lie in the plane of the pivotal axes, enabling the gap between the edges 39 to be reduced to a minimum. In the modification shown in Fig. 5, the channel member 52 is formed as an integral extension of one of the flaps, enabling the connection to be effected by a single hinge. The hinge members are inter-engaged by longitudinally sliding one into the other, after which separation may be prevented by distorting a portion of one into a gap or slot provided in the other. In the Specification as open to inspection under Sect. 91, but not as accepted, U.S.A. Specifications 1,987,774 and 2,006,163 are referred to.

Filed: 1935-06-15
Abstract: 438,702. Grinding. NORTON CO., New Bond Street, Worcester, Massachusetts, U.S.A. June 15, 1935, No. 17298. Convention date, Aug. 13, 1934. [Class 60] [See also Group XXII] In a grinding-machine in which a work-holder is rotated continuously during grinding, automatically operated means is provided for stopping the work-holder in such a position that it supports the work, even when unclamped, in that position. As applied to the grinding of a crank-shaft, the machine comprises a grinding- wheel 19 on a slide 11 movable towards and from the work 18 by hand-operated gearing 25-31 or by power, and two work-holders 35 carried by shafts 36 in heads 89 on a table 15 movable on ways 16, 17 by hand-operated gearing 20-23 or by power. The shafts 36 are driven by chains 45 from a shaft 48 driven through a chain 51, from a shaft 53 carrying a slidable clutch-member 55, which may be engaged with a driven member 56 or with a brake member 58. The clutch-member is moved by a yoke 60, pivoted at 61 and operated by a link 62 having a slotted end 64 connected to a pin 65 on a rock-arm 66 moved by a lever 70. The yoke 60 also is operated, to stop the rotation of the work-holders at the desired position, with the work supporting surfaces 37 thereof at their lowermost position, through a link 81, by a solenoid 80, energized from mains 82 through a switch 88, which is held normally open by a plunger 91 on a bell-crank lever 92, moved forward by a chain 95, lever 97, and link 98, when the control lever 70 is moved into slot 71 in a plate 72 to start the machine. When the work is finish ground, the lever 70 is moved back, but owing to the slot connection 64, 65 does not move the clutch-member 55, this being moved by closing of the switch 88, by means of a cam ring 102 adjustably mounted on one of the holders 35, the ring having therein a depression, which is entered by a roller 108 carried by the arm 110 of lever 92, thus allowing the lever to move and the switch 88 to close, with consequential energization of the solenoid 80.

Patent GB-568476-A (GB)
Title: Improvements in or relating to the control of selectors such as used in automatic telephony
IPC: H04Q1/18
Filed: 1943-10-22
Abstract: 568,476. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Oct. 32, 1943, No. 17423. [Class 40 (iv)] In a register-controller system of the kind described in Specifications 555,530 and 563,666 in which the driving circuit of a selector is maintained in the register-controller until the selector sends back an A.C. signal that matches a selected reference current, the driving circuit includes the discharge path of a grid-controlled gas-discharge tube which is made non-conductive on the receipt of the correct signal. As shown, the operation of relay Chr makes a charging circuit for condenser Cl, thereby momentarily reducing the negative grid bias of the tube Ty to start the discharge, and the selector magnet P energizes in series therewith. A condenser C3 and resistance R4 in the circuit cause the current to rise first to a high value and then to fall to a steady value sufficient to keep the magnet energized. The signal currents from wiper d of the selector and the reference current are fed differentially to an amplifier T 1 and the rectified output is applied across a resistance W in the connection between the control electrode of a cold-cathode tube T2 and a potentiometer. The potential provided by the latter is sufficient to ionise the tube when it is no longer opposed by potential across resistance W, that is, when the signal current matches the reference current. When this occurs, the negative potential appearing on the anode of T2 operates through a condenser C2 to extinguish the tube Ty and open the magnet circuit. Relay Vtr energizes and connects up Ftr, which releases Chr and extinguishes T2, so that Vtr falls back. Relay Fhr now pulls up and re-operates Chr in order to repeat the test. If Vtr fails to respond, relay Kir energizes and releases Ftr, Fhr, and the selector is restarted. If the test is successful, Vtr connects up Strwhich releases Chr and makes a D.C. test circuit for relay Tr to wiper c of the selector If the D.C. test fails, relay Gbr pulls up and operates Wlr which releases Ftr, Fhr, Str and re-connects Chr. The control anode of T2 is now connected to a different point on the potentiometer and the potential applied across resistance W is reversed, so that if the correct signal current is still present, T2 does not ionise. The selector, therefore, advances and as soon as the signal current is removed, Vtr operates and connects up Vrr to restore the original control conditions. If, on the other hand, the correct signal current is no longer present on account of the seizure of the outlet by another selector, Vtr and Vrr operate at once. In another embodiment, Fig. 2 (not shown), provision is made for alternative routing. The matching circuits including the tube T2 are duplicated and the tube Ty is extinguished when the received signal current agrees with either of two reference currents.
