Abstract: 1391159 Boots &c LENINGRADSKOE SPETSIALNOE KONSTRUKTORSKOE BJURO PO PROEKTIROVANIJU KOZHEVENNYKH I OBUVNYKH MASHIN 13 July 1973 33421/73 Heading A3B A forepart pulling over and lasting machine includes a drafting head 2 which carries a toe gripper 22 and side grippers 23, 24, and which is movable horiontally and vertically to effect drafting of upper on the last, the toe gripper 22 being movably mounted on the drafting head 2 so that it can move to a position underlying the toe of the last where it grips the upper and can then move upwardly and rearwardly to guide the lasting margin into the side grippers 23, 24. The machine also includes wipers 6, a hold down 81 and a heel clamp 67. As described the machine is suitable for incorporation in an automatic or semi-automatic production line in which the last 15 (Fig. 10) is mounted on a carrier 14 which is moved intermittently along the line by a conveyor (not shown). When the last 15 and carrier 14 reach the machine the carrier 14 is clamped in position by clamps 13 (Fig. 11). The upper is then placed over the last 15, the position of the heel end of the upper being determined by a spring loaded stop 71 (Fig. 10) carried by the arm 68 supporting the heel clamp 67, and when positioned the heel clamp 67 is operated by cylinder 74. The drafting head 2 is then moved forwardly by cylinder 20 (Fig. 11) and downwardly by cylinder 18 to its operative position above the last 15. The toe gripper 22 (Fig. 3) is then lowered by cylinder 38 and is simultaneously moved forwardly by a cam plate 40 on the gripper housing engaging an abutment strip 41 on the drafting head so that the gripper 22 underlies the toe portion of the last. The lasting margin is then introduced into the toe gripper 22 which is then closed by cylinder 32 and is raised by cylinder 38 to impart a longitudinal pull on the upper. During this movement the side portions. of the lasting margin are automatically guided into the side grippers 23, 24. The hold-down (Fig. 11) is then moved by cylinder 83 into contact with the insole on the last bottom. The side grippers 23, 24 are then closed and the drafting head 2 is raised by cylinder 38 and moved rearwardly by cylinder 20 to tension the upper about the last. The slide 7 carrying the wipers 6 is then moved forwardly to its operative position by cylinder 58 and the wipers 6 are then operated by cylinder 60. During the operation of the wipers 6 the grippers release the upper and the hold-down 81 is raised. After a predetermined time lag the various parts return to their initial position and the conveyor moves to remove the lasted upper and to introduce a fresh last into the machine.

Title: Improvements in or relating to data link communications
Inventor: CRUMP ARTHUR EDGAR
IPC: H04L7/06
Filed: 1967-07-21
Abstract: 1,237,073. Synchronous communication systems. PLESSEY CO. Ltd. 21 Oct., 1968 [21 July, 1967], No. 33659/67. Heading G4H. In a communication system data is transmitted as a sequence of information pulses alternating with synchronization pulses, the receiver including scanning means responsive to the synchronization pulses to direct the information pulses to receiving means. A group of switches 5 is sampled by a ring counter 4 advanced by pulses from a clock 7. The synchronization pulses are negative and the information pulses are positive to represent " O " and zero to represent " L", as shown in Fig. 2. At the receiver the synchronization pulses are detected at 12 and passed via a unit 13 to step the distributer 6 which is an eight-stage ring counter. The information pulses pass via the distributer 6 to corresponding sections of a store and are indicated by the lamps of an indicator 10. The counter 4 has eight stages, the last three sending no signal so that a blank interval is provided during which the counter 6 is reset to its eighth position. For this purpose a blank space detector at 13 opens gate 8 to allow pulses from a clock 9 to pass to the counter. When the counter 6 reaches the eighth position, the gate 8A is disabled to prevent further counting. The first synchronizing pulse from the transmitter steps the counter 6 to the first position and the following information bit passes to the appropriate position of the store. If, due to spurious pulses, the counter is returned to its initial position when the long period of no signal is detected at 13. The store may be arranged to accept information bits only if they have been repeated three times in three consecutive cycles. Instead of using pulses of opposite polarity, bursts of different frequency may be used.

IPC: B66C13/40
Filed: 1966-07-27
Abstract: 1,092,849. Endless belt conveyers. ELEKTROPROJEKT BERLIN VEB. July 27, 1966 No. 33744/66. Heading B8A. [Also in Division H2] The main switchgear for the drive of a crane, conveyer, or the like is adapted for remote control, either directly from a cabin, or indirectly through a radio link. When a selector switch aO1 is positioned for cabin control, a pushbutton b11 is actuated to energize relay d13 whereby coil a51 of the main switch is supplied with rectified current. A no-volt trip coil a52 of the main switch has its circuit completed through overload trip e, door contact b, push button b10, crane seat switch b1, and pushbutton b12. The switch b1 is shunted by holding contacts of the main switch. For radio control, the contacts of the selector switch are opened, and, if there is satisfactory transmission, a relay is operated to close contact d12/3-4 and open contact d12/9-10. The circuit for the trip-coil a52 is thus completed. Actuation of a further push-button in a portable control apparatus energizes a relay d11 to complete the circuit for the coil a51. In another arrangement, the main switchgear is driven by an electric motor which is moved automatically to a neutral position when the relay d12 is de-energized or the no-volt trip is actuated. After the switch-on operation is completed, the motor is actuated. After the switch-on operation is completed, the motor circuit is interrupted and is prepared for reversal. The position of the selector switch is indicated by warning lamps.

Title: Improvements in diversity receiving systems and control circuits for use therein
IPC: H04L1/06
Filed: 1946-11-18
Abstract: 635,264. Radio receiving systems; frequency modulation valve relay circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 18, 1946,. No. 34147. Convention date, Nov. 17, 1945. [Classes 40 (v) and 40 (vi)] In a diversity receiver for frequency shift telegraph signals, the two channels are controlled by gating valves operated by a locking circuit in accordance with the strength of the I.F. signals. In both channels I.F. signals are passed to an I.F. amplifier 46, a double triode limiter 50, and an I.F. amplifier 60 to a frequency discriminator comprising a circuit M tuned slightly above the " mark " frequency and a circuit S tuned slightly below the "space" frequency. These circuits are differentially coupled to detectors MD, SD, from which potentials representing the telegraph signals are taken via a polarity reversing switch KRS to a gating valve 80. When this is conducting, the output passes to a low-pass filter 100 and to recording equipment (not shown). Signals from the two channels are also passed to I.F. amplifiers 110, 110<1>, and by band-pass couplings 120, 1201 to differentially connected diodes 182, 182<1> whose output potential is proportional in magnitude and direction to the relative signal strengths in the two channels. This potential is passed via an amplitude limiter 230 and a cathode follower valve 198 to one valve 200 of a multivibrator 200, 204, which controls the two gating valves 80, 80<1> through bias resistors 216, 2161. A second cathode follower 198<1> having the grid earthed, is connected to the other valve 204 of the multivibrator to balance the change - over circuit when there is zero voltage on the grid of valve 198, so that when both channels are receiving signals of equal strength, the multivibrator remains stable in one position or the other. In an alternative embodiment, Fig. 3 (not shown), the I.F. signals of the two channels are applied directly to the gating valves-in this case H.F. pentodes-in addition to being applied as before to discriminating and locking circuits. The selected channel signals are then amplified and detected in a single circuit similar to one of the channel amplifiers and detectors of the previous embodiment. Specifications 5091/46 (as open to inspection under Sect. 91) and 635,263 are referred to.

Title: Improvements in or relating to steering mechanism for road rollers having pivotally mounted driving motors
IPC: B62D7/00
Filed: 1934-11-28
Abstract: 435,079. Steering - gear for road rollers. FOWLER & CO. (LEEDS), Ltd., J., and OWEN, W. A., Steam Plough & Locomotive Works, Leeds. Nov. 28, 1934, No. 34213. [Class 79 (v)] In road rollers in which the motor driving the roller is movably mounted about the main roller axle, power steering gear driven from the driving motor includes transmission mechanism comprising a sliding part or parts and universal joints which are not affected by the movements of the motor. In the construction shown the steering roll is mounted in a steering head 44 rotated by a shaft 2 through bevel gears 1, 3 and worm and sector gearing 4, 5. The shaft 2 can be rotated directly by the co-axial hand-wheel shaft 2<a> or can be power driven from a coupling 13 on the movably-mounted driving motor (not shown). The coupling 13 is connected to a shaft 10 which drives the shaft 2 through bevel gears 11, 14, universal joints 18, 22, a telescopic shaft 21, bevel reversing gear 25<c> and chain gear 30. The reversing gear comprises bevel pinions 25<a>, 25<c>, Fig. 2, adapted to be clutched one at a time to a slidable shaft 26 by friction clutches 32, 33. When the steering gear is to be driven from the motor the steering hand wheel 6 and its shaft 2<a> are pulled axially to the position shown in full lines in Fig. 1. In this position a clutch 47 on the shaft engages an arm 35<a> so that when the shaft is rotated the arm rotates therewith and by means of linkage (not shown), rocks a fork 37, Fig. 2, and moves shaft 26 axially to cause one or other of the clutches 32, 33 to be engaged to drive the shaft 2 and steer the roller in the desired direction. Should the power steering gear be left engaged too long one of a pair of limit pins 40 on the worm sector 5 engages a lever 38 connected to the clutch fork 37 and restores the reversing gear to the neutral position. When the roller is to be steered by hand the hand wheel 6 is moved axially to the dotted line position in which clutch 47 on shaft 2<a> is disengaged from arm 35<a> and engages clutch teeth 9 on shaft 2. The driving motor may be started by hand by means of a starting- handle spindle 12<a> and clutch and bevel gearing 12e.
