Title: Synchronizing system
IPC: H04N1/36
Filed: 1966-09-27
Abstract: 1,140,456. Automatic speed control. XEROX CORP. Sept.27, 1966 [Oct. 1, 1965], No. 43086/66. Heading G3R. [Also in Division H2] In a synchronizing system, oscillator 10 is connected to frequency divider 12 whose output is amplified and applied to motor 16 having a permanent magnet rotor so as to afford a fixed relationship between the position of the motor shaft and the phase of the applied voltage. The motor is geared to facsimile drum 20 to which is fixed a cam 26 for operating periodic contacts 27, 29, associated with low-voltage source 30. A circuit 34 separates a synchronous signal from incoming information signals applied to terminal 32, a differentiating capacitor 40 ensuring that AND gates 36, 38, respond only to the leading edge of the received synchronizing signal. The other input of gates 36, 38, are connected to contacts 29, 27, respectively. The reset input of flip-flop 42 receives a signal from gate 38 to indicate an out-of-synchronization condition, whereby amplifier 44 energizes lamp 46. When frequency divider 12 corresponds to a count of 60, gate 50 generates a signal which passes through gate 48, due to the simultaneous presence of the signal from flip-flop 42. The signal from gate 48 passes through OR gate 52 and capacitor 54 and is applied to the re-set terminals of stages 1, 2, 3, of divider 12 which now delivers a higher frequency signal to the motor. The drum catches up with the incoming synchronizing signals so that coincidence is detected by gate 36 between these signals and those from the contact 29. Flipflop 42 changes-over to extinguish lamp 46, pulses from gate 50 being prevented from passing through gate 48 thereby restoring the unit 12 to its normal dividing ratio. Pulses from the flip-flop 42 now coincide with the incoming synchronizing signals which are passed through gates 56, 52, to re-set the divider 12 to zero whereby the phase of the voltage applied to the motor is regulated within narrow limits. The system may be modified to operate as a combined transmitter and receiver, the units corresponding to the gates 48, 56, being disabled in the transmitter mode so that the divider 12 functions as an ordinary divider and motor 16 operates at a steady speed. A three-input AND gate detects coincidence between the outputs of stages 5 and 6 of the divider and the closure of contact 29, the output of the gate being a pulse occurring once per revolution of drum 20 and accurately timed with respect to the position of the drum. This pulse serves as a transmitter synchronizing signal and is combined with information signals in an OR gate, Fig. 2 (not shown).

Abstract: 1,020,634. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. Nov. 15, 1962 [Nov. 17, 1961], No. 43198/62. Addition to 989,055. Heading A3B. The sole moulding machine of the parent Specification is modified by providing new means to separate soles from the magazine before being positioned and by providing a second magazine to receive the moulded soles. Before moulding the soles S are stacked in a magazine 40, the lowermost sole S (Fig. 3) resting on a curved table 50. This lower sole is separated from the stack by an arm 52 which has a wedge-shaped abutment 54 which engages the lower sole with its leading edge, and lifts the stack slightly with its trailing edge to allow free movement of the lower sole. The arm 52 is rotated by a cam groove 64 via a lever 60 and takes the sole to the end of the table 50 where it is held by springs 92. The sole is then positioned lengthwise and widthwise, moved to the mould and moulded as described in the parent Specification. During moulding part of the sole S extends beyond the mould 34, 36 (Fig. 9, not shown) and is gripped by grippers 210, 212 which are mounted on a carriage 214 on a rail 216. After moulding the grippers carrying the sole are moved back by a cable 224 which is connected to the mould carrier via a rack 250 and pinion 244. When the carriage 214 reaches the end of the rail 216 the arm 220 of the lower gripper 212 engages an abutment 280 to release the sole, and a roll 296 on the carriage 214 engages an arm 298 to rotate the arms clockwise (as in Fig. 9, not shown) to pack the sole in the second magazine 284. The moulded soles are supported by a plate 286 which rests on springs 294 which are depressed by the weight of the soles so that the uppermost sole stays at a constant level.

Valve 78 is caused to close to disconnect chamber 156 of the modulator 24 from vacuum induced by the inlet manifold 82 and valve 76 is opened to atmosphere. This causes movement of walls 117, 118 against the action of springs 128, 130, which causes movement of plungers 180, 182 to close valves 196, 198 in inlets 188, 190 and to -increase the volume of the front and rear braking systems. This results in braking pressure on the sets of wheels being reduced until the control sensor 62 again acts on the solenoid valves 76, 78 to cause renewed braking. In the embodiment of Fig. 3 the modulator 208 has chambers 238, 242 connected to a vacuum check valve 250 via a conduit 248 and a conduit 252 connects a solenoid valve 254 to the valve 250.

Surfactants: non-ionic condensates of ethylene oxide (or propylene oxide) groups with lauryl alcohol, stearic acid, nonyl phenol, resin, dodecyl mercaptan, octylamine, lauryl mono-ethanolamide and tallow sugar glyceride. Solvents: (i) pentane, hexane, heptane, iso-octane, nonane, cyclohexane, methyl cyclohexane, benzene and (ii) nonane, n-decane, n-dodecane and n-hexadecane.

To produce an error-free reproduction of a punched or magnetic tape, an operator, when recording on the original tape, records an "accept" or reject" character after each data character according to whether it is recorded correctly or not, and this tape is then run through a reproducer in the reverse direction, the reproducer being controlled by the accept/reject characters to reproduce only the correctly recorded data characters. In the reproducer shown in Fig. 2, two sets of switches 131-135 and 241-245 are set in accordance with each character sensed, switches 131- 135 selectively energizing punch solenoids 111- 115, and switches 241-245 supplying a decoding matrix 20. Each accept/reject character is preceded by a "case shift" character, this character being for example, five holes so that switches 131- 135 in the "hole" position break the energizing circuit of thyratron 265 to apply full potential over resistor 170 and lead 270 to matrix 20. A following accept/reject character then causes one of leads 192, 194 to be energized to set bi-stable pair of thyratrons 150, 152 to the corresponding state and in turn energize reject relay 16 if a reject character is sensed. Relay 16 interrupts the energizing circuit of the punch solenoids 111-115 to prevent recording of an erroneous character and also to prevent energization of the reproducer tape drive solenoid 76. While a character is being sensed, contacts 96 close to complete the circuit for solenoids 76, 111-115, and contacts 338 open to remove earth from lead 330 and enable matrix 20.
