Title: A method of treating thread and a machine therefor
IPC: D06B3/04
Filed: 1949-04-23
Abstract: 681,547. Coating threads. DAN RIVER MILLS, Inc. April 23, 1949. [April 24, 1948] No. 10812/49. Class 140. Thread is treated by conducting a plurality of ends from supply spools to a treating bath, applying a treating solution while twisting and untwisting the thread to ensure saturation a low tension being exerted on the threads prior tc entering the treating liquid tc remove residual stretch, elongating the threads while partially drying, compressing the partially dried threads and further drying prior to distribution to take-up spools. Threads from supply spools, after the application of the low initial tension, pass over driven groove reverse roll 25 to apply uniform tension thereto, and under, between and over pairs of rolls consisting of driven dipping rolls 26, 27, 28, which apply bonding liquid from tank 41 and associated reciprocating compression rolls 36, 37, 38, which may be rubber covered, to compress, twist and untwist the threads giving uniform saturation. The threads pass round driven stainless steel dip roll 40, which may be the same size or larger than rolls 26, 27, 28 to regulate the tension or relaxation of the threads, under rubber coated squeeze roll 42 and round metal guide rolls 43, 44. The threads then pass to nip and compression rolls 46, 47, 48 and thence through drying oven 50 to roll 55, which reverses the direction of the thread. The threads run, from roll 55, through pairs of rolls consisting of driven metal rolls 56, 57, 58, which are rotating at a greater speed than rolls 46, 48 of the nip and compression group to impart stretch or polish to the threads, and associated reciprocating compression rolls 66, 67, 68, which are rubber covered, to guide roll 69 for the second passage through the drying oven 50. The threads then pass round take-up roll 70, with a co-operating lock roll 71 to prevent slippage, round idle roll 75 and thence by individual take-up guides 76 to spools 78. Dip roll 27 may be smaller than rolls 26, 28 to relax the thread during impregnation. Specifications 548,794, 600,577 and 679,824, [both in Group IX], are referred to.

Filed: 1966-03-11
Abstract: 1,092,448. Gunn effect devices. STANDARD TELEPHONES & CABLES Ltd. March 11, 1966, No. 10812/66. Heading H1K. A voltage tunable oscillator consists of a variable voltage source and a semi-conductor body capable of exhibiting Gunn effect. The body is so shaped or doped that the resistance per unit length varies, preferably linearly, along a current path between electrodes disposed at its ends. Typically the body is of N-type gallium arsenide or indium phosphide formed as an epitaxial layer on a semi-insulating substrate of the same material. Tin electrodes are formed on it by vapour deposition followed by alloying in a reducing atmosphere with a flux. The frequency of the oscillations, which are non-sinusoidal, decreases as the applied voltage increases to move the point of generation of each pulse towards the output electrode. The voltage may be continuously applied or pulsed to reduce power dissipation.

Title: Improvements in or relating to photographic exposure meters
IPC: G01J1/42
Filed: 1936-04-15
Abstract: 473,654. Photo electric exposure meters. GENERAL ELECTRIC CO., Ltd., and STOPFORD, C. W. April 15, 1936, No. 10882. [Class 40 (iii)] [Also in Group XX] Relates to photo-electric exposure meters of the kind in which, when an exposure is to be measured, the pointer of the instrument is brought to a fixed mark by varying the aperture of the diaphragm before the cell,'or by means such as a variable resistor. According to the invention, the sensitivity of the instrument is much greater when the output of the cell is such as to bring the pointer close to the fixed mark than otherwise. The required effect may be obtained, when a moving coil ammeter is employed as the instrument, by using pointed pole-pieces to concentrate the flux at the appropriate position. The motion of the member by means of which the pointer is brought to the fixed mark is preferably logarithmic, the member being then combined with a slide rule which enables factors such as plate speed or lens aperture to be taken into account in determining the exposure.

Filed: 1970-03-10
Abstract: 1306437 Turret tuner PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 March 1970 [13 March 1969] 11439/70 Heading H3Q A station selector has a rotatable turret 7 carrying a plurality of axially adjustable abutment screws 9, a tuning slide 11 coupled with tuning means 13 and urged by spring 45 to engage a selected abutment screw 9, and a control member 15 reciprocally operable to disengage the tuning slide 11 from the screw 9 and impart stepwise rotary movement to the turret. The reciprocating movement of the control member 15 is converted into unidirectional rotary movement of a spindle 21 by a projection 23 engaging in an inclined groove or slot 25 such that the rotary movement of the spindle 21 is coupled to the turret 7 by a Geneva mechanism 27, 29, 31-33 which transmits a predetermined rotary movement to the turret 7 during part of each rotary, movement of the spindle 21 and locks the turret against rotary movement during the remainder of the movement of the spindle 21. Pressing push button 17 rotates spindle 21 due to the pin 23 and slot 25 and an arm 37 moves the stop pin 43 out of engagement with the screw 9. The spindle 21, which may be of synthetic resin continues to rotate in the same direction as the push button is allowed to return under the action of spring 19. After a predetermined rotation of the spindle an eccentric pin 27 engages in a respective groove 29 in the turret 7 so as to rotate the turret until the next screw 9 is in the operative position. During further rotation of the spindle 21 a convex part 33 engages a concave recess 31 in the turret to lock the turret in this operative position. Also as the push button 17 returns a locking projection 47 engages in a slot 48 in the turret. The selected screw 9 abuts the end of the pin 43 so as to move the slide 11 and core of a coil 13 to the selected tuning position. In a modification the pin 23 may be attached to the spindle 21 and the groove 25 may be formed in the sleeve 35. Fine tuning of the selected screw 9 is obtained by rotation of a nut 49 via a gear-wheel 51 rotated by a knob 59. During rotary adjustment of the turret 7 the gear-wheel 51 is moved out of engagement with the nut 49 by axial movement of the knob 59 due to a cross member 55 operated by pressing the push button 17. Continuous tuning may be obtained by pressing in push button 87 which allows a bar 93 to slide to the right and hold the button 87 in by portion 91 (see Fig. 2, not shown). The movement of the bar 93 moves via lever 95 a pressure cone 77 operating a flexible clutch element 73 so as to engage a friction clutch 69. Drive from a knob 61 is then coupled via worm 65, worm wheel 67, the friction clutch 69 and gear-wheel 79 to toothed rack 81 so as to adjust the tuning slide 11. When the push button 17 is again pressed its end 98 moves bar 93 so as to release the push button 87. The station selector may be used in a car radio.
