Abstract: 489,252. Looms with automatic weftreplenishment. TRIGGS, W. W. (Crompton & Knowles Loom Works) Sept. 29, 1937, No. 26339. [Class 142 (iii)] A weft magazine M is supported by a tie rod 3 and links 2, which can pivot and slide on a pin 12. It may be held in the operative position shown in full lines in Fig. 1, the lay end being then furnished with a single shuttle box and the loom being used as an automatic weft replenishing loom, or, alternatively, the magazine may be swung into the inoperative position shown in dotted lines and be retained therein by a hooked support 13, drop boxes being then substituted for the single shuttle box, and the loom used as an ordinary drop box loom. The magazine is caused to slide on the pin 12 when swinging into inoperative position, so that it is moved from a central position. It is detachably bolted in operative position to an adjustable support 4. The magazine is adjustable vertically and also towards and from the front of the loom. The lay end E at the magazine side has rearwardly-projecting ears to support a picker spindle, a horizontal slot 37 with enlargements 38, 39 to receive the picker, a vertical wall 42 and a floor 43 perforated to receive the drop box lifter rod 26. An inner box guide 17 has a groove 18 serving to position the stationary single box, and also the shifting drop boxes. The former shown detached in Fig. 3 has a floor with an elongated slot 62 for the depleted bobbins, a bunter 63 for use in the transfer operation and a binder guide. Its slotted rear wall 65 has a narrow top 70 to prevent upward movement of the shuttle and is bolted to the lay end E, a tongue 75 fitting in the groove 18, and dowels 73 fitting in holes 50, 51. The binder 80 has bolted thereto a strap 81 furnished with a screw 82 held tightly in a binder block 85 bolted down to the floor 61, a bolt 89 passing through aligned holes 85, 86, 56. A pressure finger 91 engages the strap and is loosely mounted on a shaft 92, a spring arm 96 on the shaft engaging the finger. The shaft is controlled by an arm 98. The drop boxes 100, Fig. 5, have inner and outer guide tongues fitting on the guide 17 and in a guide 104 described, furnished with a spacer block and bolted to the part 47 by a bolt passing through a hole 106, and by a bolt which may be the bolt 89 passing through a hole 109, the latter being sufficiently large to permit of slight angular adjustment of the part 104 so that the boxes may be slightly tilted. They are moved vertically by a rod 26 furnished with a spring 27 and passing through a sleeve 22, below which the rod carries a nut. The sleeve is moved upwards by a chain, and a rod 29 secured to the boxes and passing through an extension on the sleeve has a spring 31 to prevent overriding of the box lifter rod when the sleeve is raised.

Title: Improved circuit arrangement for electric traction motors
Inventor: SOMMERSCHIELD JOHN GRAHAM
IPC: B60L3/10
Filed: 1960-07-29
Abstract: 915,085. Control of several D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 21, 1961 [July 29, 1960], No. 26544/60. Class 38 (3). A traction system is provided with two groups G1, G2, of parallel connected serieswound motors, each group driving a separate axle or number of axles. If the load on group G1 is lighter than that on group G2, switches S2, S3 are closed and switches S1 S4 are opened so that resistor SR reduces the relative amount of current supplied to the group G1, particularly at standstill. As the speed increases, the relative proportion of the total torque exerted by the group G1 tends to increase, whilst the closure of switches FS3, FS4 to weaken the fields of the motors of group G2 also tends to increase the proportion of the torque produced by these motors. Suitable selection of the values of resistor SR and the field-shunting resistors maintains a desired ratio between the tractive efforts of the groups. The switches controlling the resistors may be included in the notching steps of a main controller to ensure connection of the resistors as required for forward and reverse motion of the vehicle.

Title: A method of manufacturing polyvinyl alcohol films
IPC: B29C48/08
Filed: 1959-08-04
Abstract: Polyvinyl alcohol films are continuously produced by casting an aqueous solution of polyvinyl alcohol on to a metal surface coated with a mixture of 3 to 8 parts by weight of a polyvinyl butyral resin of at least 60% butyralization with 7 to 2 parts by weight of phenolformaldehyde resin, drying the film and stripping it from the metal surface.  The phenolformaldehyde resin preferably has a mol. ratio of phenol:formaldehyde of 1,0 to 1,2.  The coating of the metal surface with the resin composition may be effected by dissolving 2 parts by weight of phenol-formaldehyde resin and polyvinylbutyral resin of 800-1,200 degree of polymerization in an acetone/methanol 6/4 w/w mixture to form a solution of 5-20% concentration solution which is applied to the metal surface and the solvents evaporated off.  The resultant coated surface is then heated for 1-15 hours at 100 DEG -200 DEG C. Polyvinyl alcohol films may be stripped from the coated surface without damage.

Abstract: 1,220,403. Motor driving arrangements. DOMINION ENG. WORKS Ltd. 4 June, 1968 [19 June, 1967], No. 26586/68. Heading H2A. To preserve balanced load conditions between a pair of parallel-connected synchronous motors driving a large gear-wheel 8 through pinions 10, the motors are rotatably mounted and the stators 14 are mechanically interconnected such that small torque changes in one motor due to discontinuities in the gear teeth produce changes in the stator reaction force which are transmitted to the other stator whereby the electrical load changes thus produced tend to cancel each other out. As shown, the motors are rotatably mounted in supports 7 and the stators have intermeshing gear teeth 22, 22a. Alternatively, the stators may have a pair of interacting lobes (23, 23a), Fig. 3 (not shown) or a pair of interacting levers (24, 24a), Fig. 4 (not shown) pivoted on a stationary support between the motors and pinned at one end to the stators. The stator of one motor may have resilient means opposing rotation thereof.

Title: Improvements in and relating to valves for distributing fluids under pressure
IPC: F16K11/085
Filed: 1954-09-14
Abstract: 774,912. Valves. PULS, E. F. Sept. 14, 1954 [Sept. 16, 1953], No. 26681/54. Class 135. In a rotary cylindrical valve for controlling the supply and exhaust of pressure fluid, e.g., oil to and from working cylinders for clutching and declutching gear trains, the ports in the rotary slide are arranged so that when it moves from one operative position to another it is floatingly supported. As shown, a valve member 2, Fig. 1, rotatably mounted in a ported sleeve 1 having a port 3 connected to a supply pump 8 and ports 4 connected to the cylinders is formed with an axial passage 5 closed at its ends and communicating at all times with the port 3. Circumferential grooves 11 and longitudinal grooves 12, Fig. 5, cut in the valve member 2 provide rectangular sealing faces 10 which cooperate with the ports 4. Radial ports 9 connect each sealing face with the axial passage 5. On rotation of the valve member through gearing 16, pressure liquid issuing from the ports 9 reacts against the sleeve 1 to maintain the valve member in radial balance in moving between operative positions of the valve. When a port 9 co-operates with a port 4 the unbalancing of the ports causes the valve member to move towards the port 4 to provide a seal until pressure in the associated cylinder builds up to pump pressure. The valve member is mounted with slight axial movement between end stops 15, 15a. Liquid from the cylinders returns to sump B through the grooves 11, 12. The circumferential grooves 11 may be replaced by a helical groove in which case the sealing faces 10 will be diamond-shaped.
