Abstract: 1,250,249. Treating staple fibres of a foamed organic polymer. E. I. DU PONT DE NEMOURS & CO. 19 June, 1969 [20 June 1968], No. 31175/69. Heading B5B. [Also in Division C3] Staple fibres of a closed cell foamed organic polymer, e.g. polyethylene terephthalate, are treated by (1) increasing the permeability of the cell walls by submerging the fibres in a plasticizing liquid and moving the fibres and the liquid through a first pipe length; (2) separating the fibres from the plasticizing liquid; (3) introducing an "impermeant inflatant " into the cells by submerging the fibres in a liquid containing the inflatant and moving the fibres and liquid through a second pipe length; (4) separating the fibres from the inflatant liquid; (5) vaporizing excess inflatant and all residual plasticizing liquid from the fibres while trapping inflatant within the cells, by submerging the fibres in a " stripping liquid " which is maintained at or above the b.p. of the inflatant and is substantially inert to and insoluble in the polymer and the plasticizing and inflating liquids and moving the fibres and the stripping liquid through a third pipe length; and (6) separating the fibres from the stripping liquid. Each pipe may have an internal coating of PTFE. The plasticizing liquid is a volatile non-solvent which swells the polymer, e.g. methylene chloride. The "impermeant inflatant " is a gas or volatile liquid which permeates the plasticized polymer but substantially does not permeate the unplasticized polymer, e.g. SF 6  or a perhalohydrocarbon such as perfluorocyclobutane or chloropentafluoroethane. The " stripping liquid " serves to remove plasticizer and excess inflatant by volatilization and may be water. The fibres may have at least 1000 polyhedral cells per c.c., the average size of which is less than 1000 Á and the cell walls being less than 2 Á thick.

Abstract: 1,251,162. Control of A.C. motors. LANDIS & GYR A.G. 8 June, 1970 [13 June, 1969], No. 27640/70. Heading H2J. [Also in Division G3] A capacitor 16 is charged by half-wave pulses derived from a resistor 13 which is vectorially related with the field winding of an asynchronous motor 10, the voltage developed across the capacitor being inversely dependentupon the speed of the motor. When the speed exceeds a predetermined value, thyristor 14 is blocked so that the motor is supplied through a diode 15 only until the speed is restored to the desired value which may be selected by adjusting resistors 18 or 19. The resistor 13 may be replaced by a Zener diode, and a resistor having a negative temperature coefficient may be used instead of the resistor 19, Fig. 3 (not shown). The speed of the motor then decreases with rising temperature. The motor may drive a blower for the transmission of heat in a regenerative furnace to maintain a constant temperature in the space surrounding the N.T.C. resistor. In another arrangement, the discharge path for the capacitor 16 comprises a transistor amplifier for increasing the sensitivity of the temperature-dependent regulation of the speed, Fig. 4 (not shown). The diode 15 may be replaced by a thyristor which is switched on and off by external signals, Fig. 5 (not shown).

Abstract: 1290587 Computer input/output INTERNATIONAL BUSINESS MACHINES CORP 25 June 1970 [14 July 1969] 30801/70 Heading G4A A data transfer system includes a transmitter and a receiver, wherein blocks of data are . transferred successively, each accompanied by a first control signal, and wherein the receiver responds to the reception of each block of data and its respective first signal by transmitting a second control signal, the system including means for defining time slots during each of which a second control signal should be received at the transmitter, and checking means for verifying that only one second control signal is received during each defined time slot. In a computer system, an I/O control unit sends bytes to a CPU each accompanied by a "service in" pulse, or uses "service in" pulses each to request a byte of data from the CPU. In either case, the CPU sends a "service out" pulse to the I/O control unit in response to each "service in" pulse received. A plurality of each type of pulse may be in transit simultaneously. During each cycle of a clock in the I/O control unit, a "service in" pulse is sent and a binary delay counter is incremented. When the delay counter reading agrees with a manual switch setting (indicating the time for a "service in" pulse to get to the CPU and the corresponding "service out" pulse to get back) as determined by -AND gates, incrementing stops, "service out" pulses are looked for in each subsequent cycle and an error indication is given if no such pulse or more than one is found in any cycle. A ring byte counter is preset with the number of bytes to be transferred, and decremented by each "service out" pulse received until equality with the (now stationary) delay counter when transmission of "service in" pulses is stopped. A reset signal is generated when the byte counter reaches zero, this decrementing to zero with no more "service outs" being received indicating that the correct amount of data was transmitted and received. The I/O control unit includes an I/O data register on the CPU side and a write and a read data register (for parallel-to-serial and serial-to-parallel conversion respectively) on the I/O device side of the I/O control unit. Fig. 8 shows the binary delay counter with 3 stages each being a + OR and a -AND cross-coupled to form a latch, the counter being driven by pulses on inputs 400, 401 alternately (from respective sides of a clock-driven drive trigger, but gated off when the count reaches the manual switch setting- see above). The delay circuit 431 shown in a feedback connection inverts its input and delays it for slightly more than one quarter of the clock cycle.
