Title: Improvements in or relating to a process for crimping textile thread
Inventor: BILLION JACQUES
IPC: D02G1/02
Filed: 1954-02-10
Abstract: 746,410. Crimping yarns. BILLION & CIE. Feb. 10, 1954, No. 3961/54. Class 120 (3). Thread is crimped by winding it at least once around a support, drawing the thread by one end when it is thus wound, and thermally fixing the deformations in the thread as they are being produced; the thread may be wound upon itself, Fig. 2 (not shown), or two threads may be wound around each other, Fig. 3 (not shown), to provide the support, or the thread may be wound around a smooth cylindrical support or in a helical groove formed therein. The thermal treatment may comprise passage through an enclosed space such as a steam chamber, or a hollow cylindrical tube or spirallywound electric coil, or over a plate or support heated externally or internally by electrical resistances or infra-red rays. In the process illustrated in Fig. 4 a polyester thread 22 is drawn off a bobbin 23, passed over tensioning means 24 and wound forty times about a helically grooved metal shaft 25, rotation of which within the ends 27 of a housing heated by a plate 28 advances the thread which is drawn off on a support 30. As shown in Fig. 5, three nylon threads 33, 34, 35, pass over a wetting roller 42 revolving in a tank 43 of water, through eyelets 39, 40, 41, and are twisted together, in which state they rub over a cylindrical glass tube 50 containing electrical resistances which raise the outer temperature of the tube to 150 C.; each thread is then driven by a thread-feeding device 44, 45, or 46, and received on a bobbin 47, 48, or 49. A thread-feeding device, Fig. 6, for drawing off the crimped thread, may consist of driven rollers 51, 52, on which the thread 53 executes sufficient turns for it to be driven at the peripheral speed of the rollers with little or no slip, the thread being received on a support 54 without tension so that the full crimp is retained.

Title: Improvements in or relating to circuit arrangements for television receivers
IPC: H04N5/57
Filed: 1961-02-03
Abstract: 898,913. Automatic gain control. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 3, 1961 [Feb. 6, 1960], No. 4155/61. Class 40(5). [Also in Group XL(b)] Relates to a television receiver in which the anode of the video output valve 1 is directly connected to a control electrode 13 of the display tube 5 and also to a control electrode 15 of a valve 7 which supplies the automatic gain control voltage. In accordance with the invention, the contract and brightness of the reproduced picture is maintained constant upon fluctuation of the receiver supply voltage by obtaining the bias voltages for tube 5 and valve 7 from a potentiometer network connested to the same supply voltage V b  as the video output valve, the potentiometer consisting of the series combination of a resistor 19 and a tapped resistor 18, whilst in parallel with the latter resistor is connected the series combination of a third resistor 20 and a resistor 21 having a symmetrical non-linear current-voltage characteristic, the junction of resistors 20, 21 being directly connected to a second control electrode of valve 7. The anode voltage for valve 7 is obtained from a second stabilizer source V c  conveniently derived from the line deflection circuit. The Specification includes a detailed discussion of the circuit operation and quotes typical circuit values. A second embodiment is given, Fig. 2 (not shown), where the video signal is applied to the control grid of tube 5. The circuits described are intended for use where the carrier is modulated negatively; for positive modulation, the diode detector 2 is reversed and the bias of valve 7 changed so that the automatic gain control is determined by the black level instead of the peaks of the synchronizing pulses. A resistor having a negative temperature characteristic is referred to in connection with resistor 21.

Patent GB-1022132-A (GB)
Title: Automatic slack adjusters for brakes
Inventor: SOBOL WALDIMAR
IPC: B61H15/00
Filed: 1964-01-31
Abstract: 1,022,132. Automatic brake adjuster; fluid pressure brake actuator. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec.15, 1964 [Jan. 31, 1964], No. 4195/64. Headings. F2E and F2F.  An automatic slack adjuster comprises a threaded first member 8, a second member 9 movable telescopically thereto, first and second nuts 11, 12 on the first member, a first spring 22 resiliently holding the first nut clutched to the parts connected to the second member and a second spring 27 extending between a sensing member 18 and the second nut 12 to resiliently hold the latter clutched to the second member, the arrangement being such that a force applied to the first member in a brake applying direction (leftwards) tends to part the faces of the clutches while an opposite force reinforces the clutching. In the embodiment shown in the Figure the adjuster is double acting, taking up or paying out according to whether the slack available is excessive or insufficient. When the clearance is correct the brake shoes engage the wheel when piston 3 has moved, with the members 8 and 9 to just cause the sensing member 18 to abut its end 21 on the adjustable stop 31. Excessive slack, however, will allow members 8 and 9 to move further leftwards disengaging clutch faces 24, 25 to allow its spring to rotate nut 11 rightwards along the member 8, compressing spring 27. On release of the brake clutch faces 16, 17 will first part as spring 27 maintains the sensing member against the abutment 31, the nut 12 chasing the face 17 as the member 9 withdraws over the stationary member 8 until the correct clearance is established and faces 16, 17 re-engage. If the clearance is inadequate the brake shoes abut the wheel before the parts 21, 31 abut. Increasing piston force then causes the strong spring 41 to yield and free the clutch faces 44, 45 to allow the sensing member 18 to rotate with the nuts 11, 12, the member 9 telescoping over member 8 until the face 21 abuts the stop 31 as in the normal application of the brakes. Brake release is as normal, the strong spring 41 re-engaging the clutch faces 44, 45 before the shoes start to withdraw from the wheel. The attachment block 35 is releasably attached to the member 8 so that manual adjustment may be made by rotating the latter to move through the nuts 11, 12. In another embodiment (Fig. 1, not shown), the clutch faces 44, 45 and spring 41 are dispensed with in an adjuster which acts only to take up excessive slack. Other embodiments (Figs. 4-6, not shown), show arrangements in which the cylinder 1 is secured to a bracket instead of being pivoted on trunnions 5, a pivoted joint being provided between the piston and the member 9. Further trunnions 85 are then provided for connection to a hand brake. Other arrangements in which the adjuster is not acted upon directly by the fluid pressure actuator are illustrated in Figs. 7-9 (not shown).

Title: Improvements in and relating to trolley-collectors for electric bus-bar duct systems
IPC: H01R41/00
Filed: 1950-02-20
Abstract: 669,714. Collectors; two-part couplings. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 20, 1950, No. 4306/50. Class 38 (i). A trolley-collector for a bus-bar duct system comprises a carriage 21 having secured to it an insulating body 22 having a plug-like extension 23 for insertion in a slot in the duct 14. Said extension carries an end blade contact 25 and side blade contacts 24 which co-operate with bus-bars 15 in the duct. Pairs of rollers 27 at each end of the carriage engage flanges 20 in the duct which form tracks for the carriage. Guide rollers 50 and projections 51 on the top of the carriage prevent lateral and tilting movement thereof respectively. By spacing the rollers 50 different distances from the centre of the carriage and providing a projection 201 on one flange 20, the extension 23 is only insertable in one position. The carriage is earthed to the duct by a spring 52. The rollers 27 are pivotable on shafts 28 and the contacts 24 are retractable so that with the rollers in line and the contacts 24 retracted, the extension 23 may be inserted into or removed from the duct. The rollers and contacts 24 are moved simultaneously by a lever 40 at the side of the carriage which is connected by a bar to the shafts 28 and by a shaft carrying a cam to the contacts 24. A spring catch 46 on lever 40 prevents accidental operation thereof. The cable 55 from the collector is clamped by screws 57 to a cradle 56 pivoted at 58 to the carriage so as to avoid sharp bends in the cable. An additional pivotal joint 59 may be provided. In a modification, Fig. 10 (not shown), the cable connection comprises a hook or eye which also serves as a handle for moving the carriage. Alternatively, Fig. 11 (not shown), a separate cable clamp and handle may be provided.

Abstract: 548,293. Cellulose derivative compositions and articles ; polyglycol ethers; compound glass. BRITISH CELANESE, Ltd. Apiil 2, 1941, No. 4412. Convention date, April 5, 1940. [Classes 2 (ii) and 2 (iii)] [Also in Group VIII] Cellulose derivative compositions comprise a mixed aryl alkyl ether of di-, tri-, or tetraethylene glycol as plasticizer. The aryl radical in. the mixed ether may be of the benzene or naphthalene series. The plasticizer may be the mixed methyl phenyl ether of di- or tetraethylene glycol. , These polyglycol ethers may be obtained by reacting one mol. of a di-halodi-ethylene glycol e.g. dichlor-diethyl' ether, or the corresponding di-halo-tri-ethylene or tetra-ethylene glycol with one mol. of a sodium alcoholate e.g. methylate or ethylate and one mol. of a sodium salt of a phenolic compound e.g. sodium phenate or naphtholate, or the sodium salt of a cresol, xylenol, resorcinol, pyrogallol, hydroquinone, or phloroglucinol. The cellulose derivative may be an acetate, nitrate, butyrate, or other ester, or a methyl, benzyl, or other ether, or it may be a mixture of cellulose acetate and nitrate. The compositions may be prepared in the form of solutions, plastic masses, or moulding powders, and they may be shaped into the form of filaments, films, rods, blocks, tubes, or other articles. Filaments may be obtained by dry or wet spinning methods. The compositions may be used in the preparation of decorative parts of automobiles, steering wheel material, laminated glass wherein a sheet of the composition is interposed between sheets of glass, coating compositions and lacquers. Natural or synthetic resins, and additional plasticizers may be incorporated in the compositions. In an example, the handle for the ice-cube tray of a refrigerator is moulded from a heatsoftened composition of cellulose acetate and methyl phenyl mixed ether of diethylene glycol. In another example, thin sheets are cast from a composition of cellulose acetate and methyl phenyl ether of tetra-ethylene glycol. The sheets are used for making laminated glass, a sheet of the composition being bonded between two sheets of glass. The Specification as open to inspection under Sect. 91 comprises also the use of polyglycol ethers of the formula R.(OC 2 H 4 )n.X, where R is aryl, X is halogen, alkoxy, or aryloxy, and n is a whole number at least 2. This subject-matter does not appear in the Specification as accepted.

Abstract: 461,775. Eye - protecting screens. SCHWEIZERISCHE UNFALLVERSICHERUNGSANSTALT. Feb. 14, 1936, No. 4444. Convention date, July 26, 1935. [Class 97 (i)] A protective shield for welders carried on the head, is rotatable to occupy a number of positions and its motion is so steered by two guides that its inclination is adapted to the direction of view at each operative position. The shield, Figs. 3 and 7, comprises opaque screens 1, 2, 3 and a transparent screen 4a all carried on a frame 5. Each side of the frame 5 is supported by links 6a, 6b rotatably connected to it at 8b, 8a and to a plate 7 at 8d, 8c. Plate 7 is rotatable about a pivot 11 on a plate 12 carried on the head-band 17, the rotation of the plate 7 being limited by a pin 21 attached to the plate 12 and engaging a slot 23 in the plate 7. For guiding the screen from its upper position, Fig. 4, to its lower position, Fig. 6, each of two arms 6a carries a cam 14 having curved surfaces 15a, 15b of equal radius, the surface 15b having its centre at the pivot 11 when the screen is in the position shown in Fig. 4, and the surface 15a having the pivot 8d as centre. The motion of the screen is as follows. The plate 7 first rotates about the pivot 11, the arms 6a, 6b being prevented from rotating relative to the plate by the engagement of the cam surface 15b with a fixed surface 13b. When the cam moves clear of the surface 13b, the pin 21 engages the end of the slot 23 and prevents further rotation of the plate. The position and inclination of the screen may now be varied by rotation of the arms 6a, 6b about their pivots 8c, 8d, this motion being guided by the engagement of the cam surface 15a with a fixed surface 13a, Fig. 6, a stop 24 on the arm 6b, Fig. 7, limiting this motion by engagement with an abutment 24a. The plate 7 is maintained in its two final positions by a spring 16 attached to a pin 22 on the plate, and to the pin 21, and the weight of the screen is supported by a spring 9.
