Patent GB-423251-A (GB)
Title: Improvements in or relating to spinning artificial silk threads, filaments and the like
IPC: D01F2/06
Filed: 1933-08-25
Abstract: Artificial silk threads, fibres, filaments, and the like are passed, between the spinneret and the godet, over a guide system comprising two or more thin tantalum wire guides.  In an example, an artificial thread emerging from the spinneret in a horizontal direction is passed over a tantalum wire guide at an angle of 150 DEG  and then under a similar guide at an angle of 60 DEG  and so to the godet. The arrangement leads to the production of threads of high dry and wet tenacity.  It is of particular advantage in the production of viscose artificial silk.  The tantalum guides are highly acid resistant and may be made as thin as 1 millimetre in diameter.

Filed: 1958-07-25
Abstract: <PICT:0864464/III/1> <PICT:0864464/III/2> An organic film is applied to a luminescent screen affixed to the face plate of a cathode ray tube envelope by maintaining the envelope in a fixed position with the face plate uppermost, applying a rotating spray of organic film solution to the screen upwardly from below and permitting the film to dry in situ on the screen. the organic film solution can be a lacquer of polyisobutyl methacrylate.  As shown in Fig. 1, a cathode ray tube 66 is supported on a ring 64 mounted on legs 61, 63, above the top plate 150 of a table 10.  A pulley 16 is rotatably supported by wheels 18 in an aperture in a plate 23 secured to the plate 150 and is belt-driven from a motor 12.  On the pulley 16 there is supported a spray-gun 51 with an extension 54 terminating in a nozzle 55. The spray gun 51 is supplied with lacquer from a pressurised circular reservoir 29 to which compressed air is supplied through a rotating air seal leading to a member 47, one side of a T-coupling 48, a pressure regulating valve 49, a pipe 50 and T-coupling 138, which also connects with the air pressure chamber of the spray-gun 51.  The actuating crank 136 of the gun 51 is controlled by a solenoid 40 operating a pneumatic valve 112.  The solenoid 40 is connected through slip-rings 36 to an external source of electrical power; a timing device may be employed to correlate its action with that of the drive motor 12.  A drain pan 67, provided with a deflector plate 68 and a flow of water, is supported beneath the tube (66).  The spray gun extension 54 (Fig. 6) comprises an outer tube 72, an inner tube 73 and a needle valve 74, associated with the actuating crank 136.

Title: Improvements relating to carriages composed of a fore-carriage and a trailer
IPC: B60D1/50
Filed: 1922-09-08
Abstract: 188,308. Schneider et Cie. Oct. 29, 1921, [Convention date]. Couplings for road vehicles.-In an animal- or tractor-drawn road vehicle comprising fore- and rear-carriages connected together to allow relative rotation in any plane, the weight of the forecarriage and draught pole is balanced by an elastic buffer arranged between the forecarriage and a point on the pivotal connection between the fore- and rear-carriages, the buffer acting obliquely with respect to the plane of the forecarriage chassis. As shown in Figs. 3 and 5, the axle B of the forecarriage A carrier a sleeve F formed with upper and lower trunnions E mounted in a bracket G which is pivoted to the chassis C on a longitudinal pivot H. The draught pole D is fixed to the forecarriage A. The buffer consists of a spring I bearing at one end against an abutment J pivoted at j to the lower trunnion E, and at the other end against a washer E on an adjustable sleeve M carried by a rod N ball-jointed at n to the forecarriage A. The washer K slides in a cylindrical guide L and the rod N terminates in a head n<1>. Two such buffers may be arranged symmetrically about the central longitudinal axis of the vehicle; and the buffers, instead of being connected to the chassis beneath the axle B, may be connected thereto above the axle, the spring being arranged in tension. A known method of balancing the weight of the forecarriage A and draught pole D is shown in Fig. 2. The weight of the chassis C, which is connected to the forecarriage by a king-bolt a<2>, tends to keep the forecarriage in such a position that the supports a, a<1> normally bear against the chassis.
