Title: Improvements in or relating to wire card raising machines
Inventor: PILKINGTON NORMAN
IPC: D06C11/00
Filed: 1956-04-07
Abstract: 821,850. Wire card raising machines. TOMLINSONS (ROCHDALE) Ltd. April 8, 1957 [April 7, 1956], No. 10682/56. Class 42 (1). A planetary type of wire card raising machine of the single or double-acting type is characterized by the provision of visual means for indicating the amount of raise given to a fabric by the rollers. The rollers 8, 9 are disposed between two discs 6 which are rotated by the shaft 7. This shaft also drives two infinitelyvariable gear-boxes 16, 22 which in turn drive pinions 17, 21 which engage two large gearwheels 13, 20 which can rotate independently of the shaft 7. Alternate rollers 8 are driven by belts 11 which are fixed to the lug 12 on the gear-wheel 13. The other rollers 9 which may have card teeth pointing in the opposite direction to those of the rollers 8 are driven in a similar manner by the gear-wheel 20. By providing helical gears between the pinions and gear-wheels the force exerted by the rollers on the fabric passing over them can be measured in terms of the axial thrust on the pinions 17, 21 by thrust meters or dial gauges 24 which therefore give an indication of the amount of raise given to a fabric by the rollers. This can then be varied by varying the speed of the gear-boxes 16 and 22; " zero raising " occurring when both meters are at zero. The necessary helical gears may be disposed inside the infinitely variable gear-boxes and the thrust meters may be replaced by an electric motor with a known synchronous speed and a stator rotating at slightly above the synchronous speed to produce an indication on a dynamometer.

Title: Apparatus for testing the aerodynamic balance of airscrews
IPC: B64C11/00
Filed: 1941-08-21
Abstract: 552,154. Testing balance of rotary apparatus. DE HAVILLAND AIRCRAFT CO., Ltd., and HALFORD, F. B. Aug. 21, 1941, No. 10691. [Class 106 (ii)] Apparatus for testing the aerodynamic balance of air screw blades comprises an air screw hub 15 arranged for the reception of one or more production blades P to be tested against a master blade or blades M, driving means 11 for the hub being mounted therewith so as to be free to oscillate about an axis transverse to the hub, means 17, 19, 18, 16 for adjusting the pitch of at least one blade and means 23 for indicating the oscillations of the assembly. The motor 11 is supported by links 13, 14 on a rigid stand 10 and drives the hub 15 through reduction gear 16. Extending back from the motor is an arm 20 held central by springs 24, 25 and a stylus 21 thereon influences an electrical pick-up 22 connected to indicating and/or recording apparatus 23. The hub is faired by a spinner 26 and the remainder of the apparatus by a cowling 27. The driven wheel 28 of the reduction gear is fast on the shaft 29 on which the hub 15 is splined. The shafts 30, 31 are normally stationary, the shaft 30 being keyed to the end plate 32. The shaft 31 may be rotated by bevel gear and worm gear 33, 34 from the hand-operated shaft 19. Toothed annuli 35, 36 normally rotate with the air screw, the pinions 37 idling. If the sun wheel 39 on shaft 31 is rotated relative displacement of annulus 35 with respect to the air-screw takes place, and this rotates the gears 41, 42, Fig. 4, and the oppositely-threaded screws 43, 44 which abut against lugs 47, 48 on the boss of the adjustable blade to cause its pitch to be varied. To unseat the blade, the drive shaft 15 is provided with projecting studs 49 and the spider arm 50 is placed over the stud and forced home by a differential screw 51. The blade P is placed on the spider arm and secured by caps 57 threaded on to barrel projections 58 the usual packing being provided. In operation, the production blade is set by hand to the nominal pitch and the apparatus run up to resonance speed. The pitch of the master blade is then adjusted so that there is minimum vibration. The amount and direction of pitch adjustment being found, the blade P is marked in such a way that by reference to a standard marking it can be mounted in a production air screw hub in the best condition for aerodynamic balance. Where a hub is intended for three blades, two master blades are employed against a single production blade for test.

Title: Improvements in or relating to counting apparatus
IPC: G06M1/10
Filed: 1937-04-16
Abstract: 494,154. Motors ; photo - electric counting apparatus. IGRANIC ELECTRIC CO., Ltd., and WRIGHT, S. R. April 16, 1937, No. 10904. [Class 35] [Also in Groups XIX and XL] The movement for operating the count indicator in a counting apparatus is effected in response to successive electrical impulses derived from the articles to be counted, the movement being produced in an eddy current rotor by means of out-of-phase fluxes derived from the impulses. A disc 1 of silver or other non-ferrous metal rotates between two polepieces 2 each of which is slotted at 3. Exciting coils 4 embracing the poles are connected in series to receive impulses from a photo-electric cell, the illumination of which is interrupted periodically by articles carried by a conveyer, and one branch of each pole carries a secondary coil 5, the coils 5 being connected in a closed circuit including a variable choke 6. The arrangement is such that when the current in the coils 4 is interrupted, a secondary current is induced in the coils 5 whereby a torque is developed to move the disc. When the current is reestablished in the coils 4, the torque is nullified and the disc is braked. The angle through which the disc turns for each impulse may be determined by adjustment of the choke 6 which governs the phase relationship between the primary and secondary fluxes through the disc. A permanent magnet 16 may be provided for additional braking of the disc. The current impulses for the coils 4 are transmitted through a photo-electric cell 7, Fig. 2, from a battery 8 and potentiometer 9 and are passed through a high-resistance 10 to provide a high voltage drop. This voltage is applied to the input circuit of an amplifier A, the output circuit of which feeds the exciting coils 4

Abstract: 847,461. Disc brakes. EDLING, E. G. April 7, 1959, No. 11700/59. Class 103 (1). In a spring-applied electromagnetically released disc brake, a brake disc 5, 6 rotatable with and axially slidable on the shaft 1 of an electric motor is adapted to be braked by a non- rotatable axially slidable brake disc 9 which is provided with a pair of parallel flanges 31 united at the centre by a yoke 32 carrying a pressure plate 33. The brake disc 9 is moved against the rotatable brake disc 5, 6 (provided with brake linings 7) by spring means 21 acting against longer arm 15 of a lever carried between fixed flanges 13 to move shorter arm 34 of lever against pressure plate 33. Movement of brake disc 9 and brake disc 5, 6 to the left brings the latter into frictional contact with a fixed brake disc 8. The brake is released by an electromagnet 29, which usually occurs in dependence of energization of the electric motor, and armature 28 is attracted to rotate lever 15, 34 anticlockwise and compress brake applying spring 21. The adjustment of the pressure between the brake discs when the brake is engaged and therefore of the braking torque is carried out by means of an adjusting bolt 23. A bolt 17 serves to compensate for wear of the friction pads on the brake disc. Although in the embodiment illustrated, rotatable brake disc 5, 6 is provided with two braking surfaces intended to cooperate each with one of two non-rotatable. brake discs, the disc could also be secured to the shaft and be adapted to co-operate with one axially movable, non-rotatable brake disc only.

Abstract: 1,180,448. Electrolytic production of chlorine and soda. VEREINIGUNG VOLKSEIGENER BETRIEBE ELEKTROCHEMIE UND PLASTE. March 9, 1967, No.11240/67. Heading C7B. Chlorine is simultaneously produced with soda or NaHC0 3  from solutions containing NaC1 in an electrolyzer cell wherein a saturated NaC1 solution as anolyte is separated by a continuous diaphragm, e. g. of asbestos or ionic exchange membrane, from a catholyte solution saturated with NaHCO 3 , with or without NaC1. The throughput speed is controlled so that the solution leaves the anode chamber with a content of 250-280 g NaC1/1. After electrolysis the anolyte is resaturated with solid NaCI and recycled. The catholyte is electrolyzed in such a way that the NaHCO 3  in the solution is converted into Na 2  C0 3  . After electrolysis the solution is saturated outside the cell with C0 2  and, after removing the separated solid NaHCO 3 , the mother liquor is subjected, optionally after saturation with NaC1, to further electrolysis. Alternatively, waste liquor in the Solvay process, after separation of solid NaHCO 3 , and containing NaC1, NaHCO 3 , NH4 HCO 3  and NH 4 Cl, may be used for the catholyte wherein the NaHCO 3  is converted into Na 2  C0 3  and the NH 4 C1 into NH 3  and NaC1, the resulting solution being used, together with NH 3 , as the raw materials for the Solvay process.
