Title: Improvements relating to function generators for digital computing engines
Inventor: ROWLEY GEOFFREY CHARLES
IPC: G06F1/035
Filed: 1958-09-01
Abstract: 898,779. Function generators. ROE & CO. Ltd., A. V. Aug. 24, 1959 [Sept. 1, 1958], No. 27953/58. Class 106 (1). A digital arbitrary function generator, preferably for use with the digital integrator described in Specification 886,382 comprises a store a containing the gradients of straight lines approximating to the arbitrary function, a store b containing values of the variable at which a change from one gradient to another is required, and a control means l which causes a change of gradient at the output when the value of the variable reaches one of the values in the store b. Corresponding positions of the stores hold the gradient and the difference between the values of x between which the gradient lies. An appropriate difference value is gated to a register j. Incoming increments dx decrease this value until it reaches zero when a different gradient is selected, and a new value gated to j. If a dx decrement occurs the difference value in the currently selected section of store b is subtracted from the contents of j and subsequent decrements increase the quantity held in j.

Title: Textured yarns
IPC: D02G1/00
Filed: 1975-07-04
Abstract: 1510337 Textured multifilament yarns TORAY INDUSTRIES INC 4 July 1975 [15 July 1974] 28197/75 Heading D1F A substantially non-twisted multifilament yarn 20 is bulked by running it over a heated pin 26 under a tension of 10 to 120 mg/d whilst vibrating the yarn so that certain filaments contact the pin before other filaments and at such a speed that the yarn is not uniformly heated. Preferably the yarn is caused to vibrate as it passes over the pin by means 25 which may be a fluid jet, a rotating impeller or an electrically oscillated vibrator. Roller 27 is rotated at a lower peripheral speed than roller 24 in order to overfeed the yarn and thus counteract the contraction of the yarn on contacting heated pin 26. Preferably the bulked yarn is passed over a second heater (plate 28) situated between rollers 27 and 29, which rotate at the same peripheral speed, in order to eliminate loops in the filaments. Pin 26 is at a temperature between the second (glass) transition temperature of the yarn and the melting point of the yarn whilst plate 28 is at a lower temperature of between the second transition point and 25‹C below the yarn melting point. The filaments may be of polyethylene terephthalate, polyethylene oxybenzoate, a copolymer containing at least 70% of these repeating units, nylon 6, polyolefin or a vinyl polymer, and may be of triangular cross-section, various yarn parameters and methods of determining them are specified. The yarn may be plain woven or knitted to give a bulky evenly dyeable fabric. Woven fabrics do not show dye streakiness.

Title: Clothes washer machine
IPC: D06F23/00
Filed: 1962-07-24
Abstract: 935,447. Washing-machines. GENERAL MOTORS CORPORATION. July 24, 1962 [July 31, 1961], No. 28397/62. Addition to 898,296. Class 138 (2). [Also in Groups XXIV and XXXIV] A clothes washing machine has an agitator and a rotatable tub alternatively drivable through agitate and spin drums 86, 90 driven by one or two motor-driven friction rollers, with different speed ratios in the case of two rollers, and has a brake for the spin drum 90 and mechanism to bias the brake towards an operative condition. The spin drum 90 drives a tubular shaft 64, mounting the rotatable tub, through a cam assembly 130 consisting of upper and lower parts 98, 120 splined to the spin drum 90 and shaft 64, respectively. The lower part 120 has upwardly inclined surfaces 134 on which surfaces of the upper part 98 slide, limited by vertical stop surfaces e.g. 139. An octagonal well 104 in the upper end of the open drum 90 contains an octagonal brake pad 108 supported on a spring washer 110 supported by springs 116. When the spin drum 90 is driven from the motor, the surfaces of the upper part 98 slide down the surfaces 134 of the lower part 120, until the vertical surfaces 139 abut as shown (Fig. 3), thus lowering the spin drum 90. When motor drive is stopped, inertia causes the upper part 98 to ascend the surfaces 134 of the lower part 120, lifting the spin drum 90 and bringing the brake pad 108 into effective contact with a stationary brake shoe 102. Rotation of the agitate drum 86 reciprocates the agitator in the tub through an arm 88, a spherical bearing 128, a flexible connection 126 and a shaft 62. Whether agitation or tub rotation is achieved depends on the direction of the (reversible) motor. Fig. 6 (not shown) shows an alternative embodiment, identical with that in the parent Specification, except in having lugs through the spring washer 110, in which the brake bias is consequent upon initiation of drive torque to the spin drum, which winds up a spiral spring which, when drive torque ceases, unwinds and lifts the spin drum.

Abstract: 1509507 Electronic timepieces DAINI SEIKOSHA KK 9 July 1976 [15 July 1975] 28696/76 Heading G3T [Also in Division G5] In a battery driven electronic timepiece with two time displays, a device responsive to battery voltage switches from one display to the other when the battery voltage falls to a low value i.e. near the end of its working life. As shown in Fig. 3, the device 20 responsive to the voltage of battery 19 includes two FETs of opposite conductivity types providing a '1' or '0' digital output at 35 when the battery voltage is respectively, normal or low. For a digital '1' output, transistor 32G is turned on, allowing LED numeric time display a to g to be used. However if the battery voltage falls, the device 20 gives an 'O' output, transistor 32G is turned off and transistor 32R turned on so that the display is switched to diodes a' to g' to indicate that the battery needs replacing. The two displays are of different colours, for example one may be of GaP and glow green, the other of GaAsP and glow red. Each diode, as appropriate, is used to indicate minutes or hours, and is energized by a decoder circuit 14 and pulse generating circuit 17, using a quartz oscillator and divider circuit. The two LED displays a to g and a' tog' are in the form of bar segments, mounted as in Fig. 1.
