Title: Improvements in or relating to change speed gear mechanism
IPC: F16H29/22
Filed: 1928-09-19
Abstract: 322,755. La Barrera, R. G. de. Sept. 19, 1928. Variable-speed ratchet gearing comprises a driving crank B<1>, Fig. 1, the throw of which is varied by utilizing the inertion of a loose flywheel H. A slotted crank arm A is fast on engine shaft a and so is an electromagnetic clutch member I. The crank pin B' projects from a block B which slides on the arm A and has a pin K projecting into a cam groove S in the flywheel H. When member I is excited, it moves against spring J so as to grip the flywheel and produce solid driving of pin B<1>. This solid drive is normal drive. In order to change speed, the flywheel H is freed and at the same time the engine is accelerated or retarded. A relative angular movement of the flywheel causes the block B to move radially on the arm A, after which the clutch H is engaged again. The drive passes through two rods C, D to drums E, Fig. 2, oscillated thereby. The drums E are connected to a driven shaft G by reversible friction pawls P. There are two solenoids Q which act against two springs Q<1>. When the springs alone act, the drive is in one direction. When the solenoids overcome the springs, the drive is in the opposite direction.

Title: Process of making artificial filaments and product thereof
IPC: D01F2/30
Filed: 1929-09-05
Abstract: 318,629. British Celanese, Ltd., (Assignees of Whitehead, W., and Dreyfus, C.). Sept. 8, 1928, [Convention date]. Cellulose carboxylates, ethers, and xanthates; unspecified cellulose soleations. - Filaments, bristles, artificial hair, or the like, having hollow spaces therein, are produced by extruding a solution of cellulose acetate or other derivative of cellulose, such as an ester or ether, into an atmosphere having a low evaporative power to produce a slow initial solidication of the filaments or the like, and then passing the filaments through an atmosphere having a high evaporative power to produce rapid solidification. According to one method of procedure, the filaments are extruded into an evaporative atmosphere maintained below the boiling point of the solvent used, and then passed through an atmosphere at a temperature considerably higher than the boiling point of the solvent. A .further method of carrying out the process is by causing the extruded filaments to pass through an atmosphere that is nearly saturated with a solvent vapour, or with the vapours of the solvent evolved from the filaments themselves, and then passing through a drying atmosphere having a low content of solvent vapour. Since the filaments remain plastic for some distance of their travel through the drying atmosphere, they may be drawn out at or near the jet to give hollow filaments or fine denier. The, Specification as open to inspection under Sect. 91 (3) (a) comprises also the process of extruding the filaments, &c. into a coagulation bath which acts merely to skin the surface of the filaments and then passing them into a bath which causes rapid solidification of the interior of the filaments. The application of the process to the spinning of viscose is also mentioned. This subject-matter does not appear in the Specification as accepted.

Title: Ambulatory typewriter
IPC: B41J3/28
Filed: 1959-08-10
Abstract: 905,982. Typewriters &c. PALMER, G. V., and PRITCHETT, H. V. Aug. 10, 1959, No. 27262/59. Class 100 (4). [Also in Group XXVI] A typewriter typing directly on to the surface, such as plans, on which it is supported by a down-strike type bar acting through its base is power moved in a letter spacing direction at each actuation and by lowering other traction means can be moved freely to any position on its supporting surface. For typing the frame 10 is supported by power-driven belts 67 on a surface 32 and printing is effected thereon by downstrike type bars 15 actuated from a keyboard 13 striking through an aperture 30 in a transparent plate 31 which may include parallel lines to assist in aligning the machine on its supporting surface. The ink ribbon is advanced and vibrated in a conventional manner. The key levers pivoted at 20 act on a universal bar 22 to rotate a shaft 23 mounting an arm 26 also actuated by a space bar 14. The arm 26 is linked to the actuating mechanism of a compressed-gas-operated piston arrangement which operates to impart rotation to a drive-shaft of the belt 67 to impart a letter-spacing movement. Repeat operation occurs throughout the time a key is held depressed. If it is desired to reposition the machine on its supporting surface a lever 104, Fig. 3, is depressed against a lip 107 to lower housings 102 against the action of springs 106 so that balls 103 extend below the belts 67 and the machine can be pushed to any position. A third housing 102 separately controlled is provided to give a three-point support. The compressed gas may be supplied by a cylinder carried by the machine or by a flexible tube from a larger supply, the gas may operate a vane-type mechanism in place of the piston or alternatively a clutch-controlled electric motor may supply the power. In a modification the supporting belts are actuated by a solenoid mechanism which is arranged to operate only once even if the key is held depressed. In all embodiments the effective rotation of the belt drive shaft may be adjusted to give a larger or smaller letter spacing movement at each actuation.

Title: Improvements in propeller pencils
IPC: B43K21/12
Filed: 1934-09-24
Abstract: 439,906. Pencil holders. COLLINS, W. H., Excelda Works, Rookery Road, Handsworth, Birmingham. Sept. 24, 1934, No. 27318. [Class 146 (iii)] In a screw - propelling pencil holder a ratchet is provided to enable the mechanism to be disconnected when the pusher reaches the position in which the lead is ejected and to be re-engaged in order to retract the pusher. The pusher is in the form of a screw-threaded rod 10 engaging a correspondingly screwthreaded tube 9 secured in the tip 7 and a block 12 fixed in the casing 6. The forward end of the pusher is of non-circular crosssection and slidably but non-rotatably carries a lead-receiving split tube 20 movable in an enlarged part of the bore of the tip. The rear end of the pusher is flattened and engages in a tube 16 flattened for a portion of its length to provide a pair of diametrically opposite wings, the forward end 23 of the tube being enlarged and of cylindrical form to permit the pusher to rotate. The tube 16 is secured to a tube 13 rotatable and slidable in the casing 6, and provided with a member 24 formed with a number of ratchet teeth. In use, when the pusher is propelled to the forward limit, the flattened part 17 enters the cylindrical part 23 of the tube 16 and the ratchet teeth slide under the flattened part 17 without tending to screw it farther forward. On reversing the rotation and exerting a pull on the tube 16, the ratchet teeth engage the flattened portion of the pusher and cause it to be screwed back in the tube 9. After the pusher has been slightly retracted, the tube 16 is further rotated while pushing it inwards, so that when the part 17 registers with the flattened part of the tube the latter can be returned to normal position.

Title: Regulator for vacuum or compressed air brakes, applicable to fast trains and to goods trains
IPC: B60T8/32
Filed: 1933-10-04
Abstract: 426,720. Fluid - pressure brakes. HOUPLAIN, G. E., 8, Rue de Belloy, Paris. Oct. 4, 1933, No. 27356. Convention date, Oct. 4, 1932. [Class 103 (i)] A device for preventing skidding of the wheels of vehicles during braking comprises a centrifugal device driven by the wheels and adapted if the speed of rotation falls to a low value first to cut off the supply of air to the brake cylinder and then to open a relief valve to reduce the pressure. In systems comprising a first and a second cylinder on a vehicle of which the second cylinder comes into operation after the first, the device is associated with the second cylinder. Fig. 2 shows a device for vacuum brakes mounted on the end of the brake cylinder 40 which is shown of relatively reduced size. Chambers 10, 11 are connected respectively to the main pipe at 12 and to the upper chamber of the brake cylinder 40. A ball-valve 14 disposed in a cavity in a slidable member 22 controls communication between the chambers 10, 11. The member 22 is coupled for left to right movement by a one-way ball-clutch 27 to a rod 28 on which the centrifugal device acts through lever 32. A valve 15 is held open by the engagement of piston 41 with the rod 20 when the brakes are released so that both cylinder chambers are then connected to the main pipe and thus to the vacuum source the one through passage 13 and chamber 10, and the other by way of chamber 11, valve 14 and chamber 10. When the brakes are applied the valve 15 is prevented from closing by the extension 25 of member 22 as long as the speed of wheel rotation is above a predetermined value but if the speed falls considerably the movement of the lever 32 permits the spring 31 to move the members 28, 22 to the right so that the valve 15 is closed by a spring 16 cutting- off the air supply to the lower cylinder chamber while the ball-valve 14 is unseated to connect the chambers 10, 11 thus permitting air to flow to the upper cylinder chamber to reduce the braking pressure. When the wheel speed again rises the valve 14 is re-seated but the valve 15 remains closed. A similar construction adapted for a single-chamber compressed air brake is also shown, the valve 14 being replaced by a lift-valve that connects the brake cylinder to atmosphere.
