Abstract: 1,111,132. Lap doffing. T. M. M. (RESEARCH) LTD. 5 April, 1966 [15 April, 1965], No. 10875/65. Heading D1N. In apparatus for doffing a lap particularly from a scutcher wherein the doffed lap is moved axially from its lap roller which is held, a lap pin is held aligned with the roller to receive the lap during its axial movement. A lap 20 formed on drums 18, 19 is loaded 'by a hydraulic device 13, 14 on guides 15. When the lap is complete the loading head 14 is lifted to release the end of the lap roller 17 and allow the lap to roll forwards onto a carriage 21. The head 14 is then lowered to receive an empty lap roller 171 moved into position from a reserve position by a lever arrangement associated with the head. A catch 28 is lowered to engage a head (23), Fig. 2 not shown, on lap roller 17 associated with the lap on the carriage 21 and a lap pin (24) is moved into a blind hole at the other end of the lap roller (Fig. 2) to be aligned with the roller. The carriage then moves to slide the lap from the roller to the pin. During this movement levers 28, 31, 32 are rotated to a position where they support roller 17 (see Fig. 4 not shown) and when the carriage reaches the end of its travel catch 22 is lifted and pin 24 it retracted from roller 17 to allow levers 28, 31, 32 to rotate and carry the empty lap roller to the reserve position in front of drum 18. At the end of its travel tray 27 on carriage 21 is tilted by pneumatic means (see Fig. 9) to overbalance tray under the weight of the lap and cause the lap to roll away. The tray is then lowered and the carriage moved back to its lap receiving position. During this motion a chute 44 is lowered and a lap pin is fed theredown from a rotatable cylindrical lap pin magazine 33 to a receiving means which holds the pin ready to be moved into engagement with the lap roller of the next doffed lap.

Abstract: 903,806. Electronic calculating-apparatus. HOLLANDSE SIGNAALAPPARATEN N.V. March 29, 1961 [March 29, 1960], No. 11010/60. Class 106 (1). Data transfer between the buffer stores of elements of a computer, such as input and/or output teleprinter converters 4-6, tape input unit 9, arithmetic unit 3 and magnetic drum store 2, takes place over a common channel 7, the units being called in turn by an allotter 1 and themselves being capable of calling up other units and programming the transfer of data. Timing may be controlled by clock (" synchronizing ") pulses from the drum passed via line 8 and the allotter to one of ten lines forming the channel 7, or by the timing of the unit involved (e.g. the tape reader, which operates at a lower speed). Data characters are transmitted as bits over seven lines in parallel (including a redundancy bit), and a " busy " line suspends the operation of the allotter while the channel 7 is in use. The drum store 2 is able to cut off the synchronizing pulses until a required sector for sending or receiving data has reached the corresponding head.

Title: Electric motor
Inventor: SCHAEFER EDWARD JOHN
IPC: H02P1/52
Filed: 1964-03-16
Abstract: 1,060,743. Control of A.C. motors. FRANKLIN ELECTRIC CO. Inc. March 16, 1964, No. 11067/64. Heading H2J. When switch (17) is in the position shown, an induction motor is operated by three-phase windings (10), (11), (12). To run the motor at a different speed, the switch (17) selects one of the auxiliary single-phase windings (13), (14) or (15). The motor again starts as a polyphase machine, but operation of centrifugal switch (16) disconnects the polyphase windings and energizes the selected single-phase winding, Fig. 1 (not shown). In another arrangement, the centrifugal switch controls a relay which shifts the motor from the main windings to the auxiliary windings. As shown, the motor is started as a three-phase machine when switch 104 engages its left-hand contact, reversal being obtained by manual operation of switch 85. Reverse torque is applied to the motor causing it to slow down, stop, and begin operation in the opposite direction.- When switch 104 engages auxiliary winding 96, the motor is started as a three-phase machine until centrifugal switch 106 opens to energise relay 89. The motor then operates as a single phase machine at a speed determined by the number of poles of winding 96. To reverse the motor when it is running as a single-phase machine, switch 85 is actuated to shunt the coil of relay 89 through direction-responsive switch 107. The de-energization of relay 89 breaks the circuit for winding 96 and establishes the circuits for windings 101, 100, 94 to apply a reversing torque. After the motor has reversed, the switch 107 changes over so that opening of switch 106 restores the single-phase connection. In a modification, the relay 89 is energized from a coil coupled to the motor windings 100, 96, 97, 98 and switch 85 is replaced by a multiple relay arrangement.
