Title: Modified continuous filament polyester yarn and fabrics produced therefrom
Inventor: FAIRCLOUGH RODNEY JAMES
IPC: D02G1/20
Filed: 1965-11-16
Abstract: In producing a continuous filament polyester yarn having a latent or potential crimp by melt-spinning and drawing between a heated feed roll and a draw roll driven at a peripheral speed higher than that of the feed roll, the yarn, after passing the feed roll, but before passing the draw roll passes between rotating intermeshing gears and also across a stationary narrow surface which is substantially at right angles to the path of travel of the yarn, the temperature of the surface being maintained at a temperature of at least 170 DEG C and the narrow surface being so arranged in the yarn path that the tension of the yarn holds it in contact with the narrow surface, but that the angle of deflection of the yarn path over the narrow surface is kept sufficiently small to obviate mechanical deformation of the filaments, such as occurs in the so-called edge-crimping processes. The narrow surface is preferably heated to a temperature above the melting temperature of the polyester.  The yarn may pass through the intermeshing gears either before or after it passes across the heated narrow surface.  The tion treatment by heating under a reduced tension to a temperature between the second order transition temperature and the polyester.  The yarn may be further subjected to a scouring treatment in a boiling aqueous medium.  The yarn may be woven or knitted into a fabric before the scouring treatment.  The full crimp potential of the yarn is not developed by the relaxation treatment but is further developed by the scouring treatment.

Abstract: 1493817 Data processing XEROX CORP 18 Nov 1974 [26 Dec 1973] 49798/74 Heading G4A A data processor has three buses 1-3 and a control memory 22, and the address of a control word in memory 22 may be obtained by combining an address on a first one of the buses with an index value selected, under control of a particular field of a control word, from another field of that control word or from a register and placed on a second of the buses to produce a relative address to address the control memory via the third bus 3. Addressing of the microprogram store may be sequential (MAR 20 being incremented by successive clock pulses), immediate (next address supplied by microinstruction, I/O interrupt or translator 15 or as a result of a branch), or relative (the current address in MAR is added or subtracted with an emit field of the current microinstruction, or a value supplied from any B bus source). Interrupts are selected in order of priority, the selected interrupt being coded to a corresponding control memory address which is fed to memory 22 via multiplexer 28, the priority selection and address coding being performed by an interrupt handling routine entered at a fixed control memory location. Fast interrupts may be provided for, each such interrupt accessing a fixed control memory location containing a microinstruction to move data between an I/O controller and main or scratchpad memory 16, 18 to or from an address contained in a general register 10 specified by the microinstruction, this register being incremented/decremented for each data transfer. If the fast access facility is provided on more than one I/O device, then each such device has a local register providing the address for data transfer.

Title: Improvements in control systems for electrically heated devices
IPC: G05D23/24
Filed: 1966-11-08
Abstract: 1,113,909. Control systems for electrically heated bedcovers. GENERAL ELECTRIC CO. 8 Nov., 1966 [30 Dec., 1965], No. 49882/66. Heading H2H. Apparatus for preventing over-temperature occurring in an electrically heated device such as a bedcover 40 comprises two co-operating thermally responsive elements 12, 13 having associated therewith heating devices 26, 27 respectively and a pair of concentrically arranged conductors 43, 46 separated by a sensor material 53 having a negative temperature coefficient of impedance. The heat differential between the elements 12, 13 is increased by arranging a heat dissipating member in contact with the element 13 and the sensor material 53 is arranged to shunt the heating device 26. During normal operation the sensor material has a high impedance such that closure of a switch 41 establishes a circuit including heating device 27, conductor 43, heating device 26 and conductor 44. The device 26 has a higher resistance than the device 27. Thus, since the element 13 loses heat more quickly than the element 12, the element 12 deflects a greater amount than the element 13 to close the contacts 14, 15, thereby energizing the heater 46 of the bedcover 40. Should the bedcover develop an over-temperature, the impedance of the sensor material 53 will fall, causing a leakage current to flow between conductors 43, 44. The current flowing through the device 26 is thus reduced allowing the contacts 14, 15 to open to deenergize the heater 46. The contacts 14, 15 will cycle OFF-ON until the cause of the overtemperature is eliminated. Ambient temperature compensation and the operating temperature of the bedcover is provided by thermally responsive element 50 heating device 51, contacts 47, 48 and control knob 52.

Light from a source 16 passes through a hole in punched tape 12 to fall on a main photo-cell A, and an auxiliary photo-cell B is so arranged that, when no hole is present in tape 12, the output of cell B is not less than that of cell A, the outputs of the cells being subtracted to provide a signal which is independent of the transmission properties of tape 12. Cell B may be placed much nearer to tape 12 than cell A so that light diffusely transmitted through a non-perforated region of tape 12 produces an output from cell B which is at least equal to and may be greater than that from cell A. Cells A and B may be photo-voltaic and be connected in opposition. In another embodiment, Fig. 3 (not shown), light from source 16 which passes through a hole in tape 12 is reflected back through the hole on to cell A by means of a mirror, cell B in this case being responsive to light reflected diffusely and/or specularly from an unperforated region of tape 12. In either embodiment, cell B may be more sensitive than cell A or its output may be more amplified to provide the desired relative magnitudes. Baffles 23 may be placed between adjacent cells B to avoid cross-talk.
