Title: Pellet making machine
IPC: B21H7/14
Filed: 1973-08-15
Abstract: 1393483 Making pellets; rolling; punching; stamping J PACZY 15 Aug 1973 38555/73 Headings B3A B3M B3W and B3Q A waisted pellet is made by punching a slug from a ribbon of material 3 using a punch 1 and die 5 and rolling the slug using a pair of shaping members 8, 9 which are displaced to nip and spin the slug into waisted form. The shaping members may be segment or disc shaped rollers each formed with a rib 10 of increasing height. The members are rotated or oscillated in timed sequence with the punch and engage the slug before the punch reaches its bottom dead centre. Several punch and die sets may be arranged in alignment for punching slugs from a ribbon (23), Fig. 5 (not shown), fed at a small angle to the centre line (18) of the sets. The punches are driven by a common crank-shaft by a motor which also drives a ribbon feed mechanism and the shaping members. The ribbon may be made of lead.

Title: Control circuit for an electrically driven vehicle
IPC: B60L15/28
Filed: 1974-09-04
Abstract: 1525563 Control of DC motors JOSEPH LUCAS Ltd 29 Aug 1975 [4 Sept 1974] 38577/74 Heading H2J An electrically driven vehicle control circuit comprises positive and negative supply lines connected to a traction battery, a motor having an armature and a separately excited field winding connected between the supply lines, at least one recirculating diode connected in circuit with the field winding, a field current regulator, means operable to reverse the connections between the ends of the field winding and the supply lines, and switch means which, on operation of the reversal means, opens and causes current flowing in the field winding current to be diverted through the battery so as to increase the rate of decay of flux above that with the recirculating diode alone and thereby allow rapid reversal of the field current. As shown on Fig. 1, a single recirculating diode 45 is provided and the reversal means comprise a pair of switches 34, 35 connected to the ends of the field winding 31 and operable by a relay coil 36, the switch means 38 being operable by a relay coil 74 and a controller for the relay coil. In operation, and with the circuit connected as shown, field current in the direction If flows. When it is desired to reverse the current flow, a signal is removed from an input terminal 0À75 and a signal is applied to an input terminal 76 of the controller. A transistor 46 is immediately caused to conduct thereby turning off transistors 43 and 41 to disconnect the battery from the winding 31, and a transistor 73 is caused to conduct after a delay to energize relay coil 74 to open contact 38. Current then flows from winding 31, through diode 45, battery 42, diode 82 and winding 31, the battery opposing this flow and causing rapid decay of flux in winding 31. When this flux reaches zero, as detected by Hall devices 81, a gate 78 causes a bi-stable circuit 79 to change state to energize a relay coil 59 to change contacts 58, 66 over. Thus relay coil 36 is immediately energized to change over contacts 34, 35, transistor 73 is immediately turned off to de-energize relay coil 74 to close contact 38, and transistor 46 is turned off after a delay to switch on transistors 43, 41 to allow current to flow through winding 31. A field current controller 40 is provided and the armature is not shown. As shown in Fig. 2, two recirculating diodes 103, 104 are provided and the reversal means consist of four thyristors 93, 94, 99, 101. When it is desired to reverse current flow, switch 97 is opened to cause current flow through battery 102 and when the flux is zero, a field controller causes the appropriate pair of thyristors to conduct.

A vehicle transmission comprises input, counter, intermediate and output shafts A, B, C, D, the axes of shafts B, C, D passing the corners of a triangle; of the gears 36, 38, 40, 42 fast with shaft C, the gear 36 permanently meshes a reverse gear 48 rotatable relative to shaft D; and members 52, 54 are splined to shaft D and movable to connect gears 48 or 38 or 40 or 42 to shaft D to produce eight forward ratios and four reverse ratios. Shaft C can be driven direct from shaft A via gear 60, clutch 64 and gear 62 for the high forward ratios or via gears 58, 68, shaft B, slidable element 70 and gear 38 for the low ratios; for reverse ratios the element 70 engages reverse gear 48. Clutch 64 can engage fixed teeth 80 only when a gear ratio is established for a parking lock. Shaft A is driven from engine crank-shaft 12 through clutch 14, 16 and a two-speed power-take-off is driven via clutch 14, 18, shaft 22 and gears 24, 26, 28, 30.

Each rod has a member to locate it in a desired position and the rods are interlocked, whereby one rod of each pair can only be moved when the other is in neutral. Also the rods are interlocked so that parking lock can only be established when a gear ratio is established.

Title: Aircraft automatic control apparatus
IPC: G05D1/02
Filed: 1961-11-07
Abstract: 933,805. Automatic steering control for aircraft. SPERRY RAND CORPORATION. Nov. 7, 1961 [Nov. 29, 1960], No. 39812/61. Class 38 (4). A system for causing an aircraft to approach and follow a radiodefined path, automatically under the control of the sum of signals respectively dependent on displacement and rate of approach with respect to the path, is automatically engaged when the sum of the signals falls below a predetermined value. In Fig. 1a a signal dependent on displacement from a radio beam is derived through a modulator 16 from a radio receiver 14 on an aircraft and combined in a summing amplifier 30 with a signal dependent on heading error derived from a gyro-magnetic compass 22 and a course selector 18. When the two signals become nearly equal as the aircraft approaches the beam, the amplifier output, which is in pulse form, falls to a low value at which, provided a manual switch 38 is closed, a relay 32 operates to connect the amplifier output to the bank channel of the automatic pilot so that the aircraft is caused to approach the beam asymptotically. Automatic control is thus engaged nearer to the beam when the angle of approach is small than when it is large so that the automatic control does not initially increase the angle of approach to bracket the beam. A limiter 26 ensures that the heading error signal never exceeds the maximum possible value of the displacement signal. Modifications are described in which (a) separate relays control the disengagement of automatic control according to the sense of the difference between the two signals or according to which side of the beam the aircraft is approaching; (b) separate summing amplifiers having different sensitivities provide signals for controlling the relays and aircraft respectively. Specification 807,512 is referred to.

Abstract: 1,032,082. Welding by pressure. ASSOCIATED ELECTRIC INDUSTRIES Ltd. Sept. 11, 1962 [Nov. 8, 1961], No. 40001/61. Heading B3R. In butt welding the edges of two sheet metal parts relative vibratory motion is imparted to at least one of the edges whilst pressing the edges together in abutting relation, the relative motion having substantially no component in the direction of the pressure. One edge P, Fig. 2, is contacted by an axially vibrating member V and the other edge Q is mechanically clamped and welding is effected between the edges pressed together by forces C. The edge P may have a resilient backing or a second vibrator, in phase with the first, is applied to the underside of edge P. Oil or grease may be arranged between the vibrator and the edge P. When the edges of a tube blank are welded a rigid hollow mandrel M, Fig. 3, is placed within the tube, one edge Q being supported between the mandrel and a roller R while the other edge P is vibrated by a vibrator V shaped to conform to the tube surface and backed by an elastic material contained in a step S in the mandrel. An internal mandrel resonating at the applied vibrating frequency may be employed with the roller R clamping the movement of edge Q. When a mandrel is not employed in welding a cable sheath a layer of oil or grease is applied between the vibrator and the edge P and a second vibrator, 180 degrees out of phase with the first, is applied to the other edge Q, oil or grease also being arranged on the latter edge and the sheath is advanced continuously. The thickness of the sheet material to be welded may be 0À015-0À10 inch and the edges are pressed together by squeeze rollers or dies. The Specification refers to vibrating the edges at right angles to the direction B, B<SP>1</SP> in Fig. 2 and in the direction of the seam.
