Abstract: 1,051,355. Finishing yarns; knitted fabrics. DEERING MILLIKEN RESEARCH CORPORATION. Oct. 1, 1963 [Oct. 15, 1962]. No. 38631/63. Headings DIF, D1K and D1W. Cellulosic, e.g. cotton, linen, polynosic and viscose rayon, yarn which produces textured, e.g. boucle or crepe, effects when knitted or woven into fabric and wet out, is produced by imparting crimp deformations in regular, uniform pattern in the yarn, e.g. by knitting with a tight stitch in a tubular machine and then unravelling, wet cross-linking the yarn to impart considerable wet, but little dry, configurational memory thereto, and drying the cross-linked yarn before or after winding it into a package. The dry, untensioned yarn has a conventional linear appearance, the latent crimps, e.g. 3.5-12 per linear inch, being developed (and retained) when the yarn, or fabric made therefrom, is in a wet untensioned state. The basic yarn may be single or plied, spun staple or continuous multifilament or mixtures thereof. Wet, acid or alkaline catalyzed cross-linking agents, preferably applied while the yarn contains at least 15% by weight of water, include formaldehyde or epichlorohydrin and the catalyst and agent may be separately applied. The final fabric is of open or loose construction to provide full scope for the crepe &c. effects and to prevent phasing of the crimp in the wet cross-linked yarn with the stitch in the fabric. The conversion of crimp from latent to visible may be carried out in hot or cold water or steam with agitation and use of a conventional detergent. If any loss of crimp in the fabric occurs with usage, it may be restored by washing.

Abstract: 1,252,689. Programmed control of machinetools. SIEMENS A.G. Aug.20, 1969 [Aug.29, 1968], No.41624/69. Heading G3N. Tool radius compensation in the numerical control of machine tools is effected by the use of an internal interpolator and a correction interpolator, both of which are operable in accordance with a direct digital analyser method, to apply pulses to a mixing means. As shown, a punched tape 1 is read and the values applied through a logic circuit 2 to an interpolator 3, supplying pulse trains x, y to co-ordinate machine drives, (not shown). The cutter radius is introduced from a register 5 into a correction interpolator 4. The output of the interpolator 4 is mixed with that of the interpolator 3 in OR-gates 7. With continuously changing slopes at transitions of the travel curve the correction interpolator is synchronised through a scaler 6 whereby the two interpolators are pulsed at different frequencies. In a modification, for travel curves incorporating straight sections, where the interpolators operate with different computation timings, the correction interpolator is activated, with correct sign, at a timing frequency set in dependence on a comparison of registered valves corresponding to the tangent position of the interpolators. The machine drives comprise step-by-step motors and each interpolator contains two registers.

Abstract: 1,258,779. Data transfer circuits. SOLARTRON ELECTRONIC GROUP Ltd. 15 May, 1970 [22 May, 1969], No. 26248/69. Heading G4H. A data transfer unit comprises a plurality of modules including a control module, one or more data source modules and one or more receptor modules, the modules being connected by plugin multi-terminal connectors to a highway having four lines for transferring the binary coded bits of decimal digits from any source module to any receptor module and a further five lines for passing a request code from the control module to transfer decimal data between modules and a plurality of control lines for addressing the data source and the receptor modules individually to cause the bits of the successive decimal digits to be transferred from the addressed source module to the addressed receptor module. In the form described there are eleven modules each being built on a vertical printed circuit board, the boards being arranged side by side in a case. At the back of the case is a printed circuit mother board with horizontal conductors constituting the highway 12. Each module has edge contacts engaging a row of connectors on the mother board. Power unit 13 supplies pulses at mains frequency to the clock module 14 which supplies timing pulses on line 25 to the controller 17. Data is transferred, one binary coded decimal digit at a time over four lines 26 of the highway. The digits are selected by request lines 27 from the controller energized in a 2-out-of-5 code. Other control lines from the controller select corresponding ones of the modules. When a measurement is to be made the controller, by a signal on line 28, causes the clock 14 to apply signals indicating the time to the output driver 16. The clock decades are read out in succession by signals on lines 27. The data source 35, which may be a digital voltmeter, has analogue inputs over lines 39 from head units 19-22. A command pulse from interface on line 40 causes the data source 35 to digitize the input, the command pulse being given in response to a "1" signal from the controller over line 29. The interface maintains the line 29 at the "1" level until unit 35 sends a signal on line 41 indicating that digitization is complete. Unit 35 sends a polarity bit on line 42, a decimal digit on four lines 43 indicating the range of the reading and four decimal digits on sixteen lines 44 indicating the magnitude of the measurement. All these digits are passed in turn by the interface under the control of signals on lines 27. The output device is connected by lines 45, 46 corresponding to lines 40, 41 and sixteen lines through which the data is passed from lines 26 by distribution logic controlled by the signals on lines 27. Head units 19-22 each have five inputs and relays to connect a selected input to the lines 39. The relays are energized in turn by a counter in the relay driver unit 18. The relay driver can be arranged to scan the inputs in turn until a given input is reached and then stop.

The following gases were investigated as to their performance as working media in the engine: Air, Nitrogen, Carbon dioxide, Hydrogen, Helium, Argon, Sulphur Dioxide. Air and Carbon dioxide result in a better performance than the rest, with Carbon dioxide giving the best overall performance. The Fig. shows the piston on its upward stroke with the valve V 2  open. Hot gas is displaced into the cooler through the regenerator. In the space below the piston cool gas from the cooler is sucked in. On the downard stroke the gas to which heat energy has been added in the heat source expands. In the space below the piston the cool gas which has been sucked in is compressed and displaced into the heater through the regenerator, the valve V 4  being open.
