Title: Improvements in and relating to false twist devices for textile roves
IPC: D01H7/92
Filed: 1962-11-22
Abstract: False-twisting apparatus comprises a pair of members having convex peripheries and being rotatable on the same sense, the members being sufficiently spaced apart to squeeze a roving passing between them. The convex periphery of each member may be provided by a ring of rubber or porous material on the outside of a conical member supported on bearings and driven by a belt oil or water in centrally-metered amounts can be supplied to the ring from the inside of the member.  Because the rings are distorted to a greater or less extent according to the thickness of the roving between them, rovings of different thicknesses can be twisted while the members are maintained at the same distance apart.  One degree of twist can be raised by changing the speed at which the members are rotated, the extent to which the roving is squeezed varying according to the extent by which centrifugal force distorts the rings.  The members can be arranged in a row side by side as that a member cooperates with those on each side of it to treat two rovings.  Two pairs of rollers, one pair rotating faster than the other pair may be provided to draft the rovings after they leave the members.

Title: Oxygen detection method and apparatus
IPC: G01N31/22
Filed: 1962-11-22
Abstract: A particulate solid material e.g. alumina, magnesia, silica, or titania, is coated with copper by a process in which the material is treated with a solution of a copper salt e.g. copper nitrate, in water or ethanol, the solvent then being removed by heat evaporation or ignition to leave a layer of the copper salt on the material. Subsequently the material is heated for 1 - 2 hours in a tube through which hydrogen is passed, the tube being at 250-350  DEG C., to decompose the salt to copper oxide and reduce the oxide to copper. Alternatively vacuum metallizing may be employed.  The copper coated material is treated with ammonia or an organic amine and used as a reagent for the detection of oxygen in gaseous mixtures.

In a system for maintaining the level of a vehicle, each wheel is connected by links 13, 12, Fig. 2, to the piston of a wheel cylinder 11 connected to a levelling valve 19 in a fluid circuit comprising a reservoir 15 and a pump 17. The reservoir, Fig. 4, comprises a container 40 having a fluid space 42 separated from an air space 43 by a diaphragm 41 acted upon by a spring 44. The levelling valve, Fig. 3, comprises a housing 20 and a sliding spool 23 having axial bores 24 and 29, radial bores 26, 26a and 31 and annular grooves 27 and 27a. The housing 20 has a recess 21, radial bores 22, 28 and 30 extending into the recesses 21 and groove 27 and 27a respectively, in the shown position of the valve spool, and a longitudinal bore 38 connecting the recess 21 with a chamber 32a formed by a flexible bellows 32 and a plate 33 connected to the valve spool 23 and acted upon by a spring 34a, the chamber 32a being contained within a cap 36 into which air may be pumped through a one-way valve 37.. The bore 29 is closed and a piston 25 is located in the bore 24. In the position shown, corresponding to the normal riding height, the pump 17 is short-circuited by the passage 38, represented in Fig. 2 by the line 39, and the cylinder 11 is connected by the line 16 and passage 28 to the bore 27, the forces on the spool 23 due to the fluid pressures in the bore 24, and chambers 21 and 32a, and the pressure of spring 34a, being in equilibrium. If a load is applied to the vehicle, increasing pressure in the bores 28 and 24, the spool is moved against the action of spring 34a and pressure of the gas in the chamber 36a, and the groove 27 comes into register with the bore 30, the pressure fluid from pump 17 now being delivered to the wheel cylinder to restore the vehicle height. If the load upon the vehicle is decreased causing a drop of pressure in the bores 28 and 24, the spool will ascend to the position whereby the groove 27 opens into the chamber 21 and thus exhausts to the reservoir whereby the vehicle height is diminished.

Abstract: 1354715 Cinematography EASTMAN KODAK CO 30 Sept 1971 [1 Oct 1970] 45574/71 Heading G2E A film handling device for smoothing the transport of film between a continuous spool drive and an intermittent gate mechanism includes a film guide, a film driving member connected to a motor 20 by a tendency drive 15 and a force attenuating device within the guide for braking the film.  As shown in Fig. 1 film F passes from supply reel 12 to gate 34 via a guide 24 defined by walls 26, 28 and roller 30. The guide 24 is of sufficient width to permit the film F to buckle but not to double over itself. The film F is driven into the guide by wheel 18 powered by a constant speed motor 20 through slip clutch 22. The film F is rapidly advanced that the film claw 36 cannot cope and hence the film F buckles. However to prevent the pressure plate 34 being forced back by the build up of film in the guide 24 the contact between the film F and the walls 26, 28 attenuates the force applied by the wheel 18 to an acceptable level. The wheel 18 and inside surfaces of walls 26, 28 may have a high friction coating to provide positive film movement and force attenuation respectively. In reverse projection the film movement is attenuated by contact with the wheel 30 which is locked by brake 32 except during threading. In the projector of Fig. 2 the wheel 18 is replaced by sprocket 54, the guide 48 has walls 53, 55 spaced to prevent buckling and has two lockable rollers 58, 60 which with the inner surfaces of walls 53, 55 provide the force attenuating device.
