Abstract: 868,725. ENGLISH ELECTRIC CO. Ltd. Oct. 1, 1959 [Oct. 8, 1958], No. 32175/58. Class 40 (1). [Also in Groups XIX and XXXII] A tensiometer includes in combination spring means 26 supported by a supporting structure (not shown) and having a spring rate which increases with increase in spring stress, material engaging means 16 mounted on the supporting structure for movement relative to the spring means when engaged by a strip or the like material 10 for stressing the spring means in dependence upon a force exerted on the material engaging means by the material, and electric signal producing means 28 for producing an electric signal dependent on the displacement of a part of the spring means or material engaging means from a predetermined datum position. Strip material 10 passing over rollers 14 and 13 between the last stand 11 of a rolling mill and a coiler 12 is engaged by a roller 16 mounted in a carriage 17 which slides in bearings 18 and is connected through a linkage 19 to a carriage 20 slidably mounted in bearings 22 and carrying a roller 21 which engages a spring 23 secured rigidly at one end by a clamp 24 to a supporting member 26. The surface 27 of the latter is so profiled that displacement of the spring 23 from the zero position 23a is proportional to the logarithm of the tension in the strip material 10. Displacement of the spring 23 is measured by a synchro generator 28 having coupled to its rotor shaft an arm 29 carrying a roller 30 which is maintained in contact with the spring 23 by a bias spring 31. Input terminals 32 to the rotor winding of the generator 28 are connected to an A.C. source 33 and an output signal obtained from terminals 34 connected to the stator winding is proportional to the displacement 0 of the rotor and therefore to the log. of the strip tension. Various possible connections of the stator windings of the generator 28 are described (Figs. 2 to 7, not shown), together with circuits for obtaining a D.C. output signal dependent on the deviation of the strip tension from a pre-set value determined by the circuit constants. In alternative arrangements the lever arm 29 is operated directly by the linkage 19 or (Fig. 8, not shown) bears on a roller mounted on the spring 23.

Abstract: 493,239. Non-automatic couplings for vehicles. BUGATTI, E. Nov. 23, 1937, No. 32247. Convention date, Nov. 25; 1936. [Class 103 (v)] In a ball-and-socket coupling for vehicles of the type in which the socket is formed of two readily separable parts to facilitate coupling and uncoupling, the division between these parts lying in a plane at right-angles to the longitudinal axis of the vehicles, one part has a stem lying in such axis and is secured to one vehicle, while the other part is mounted on the opposed vehicle so as to be universally movable relative to the ball of the coupling and adapted to engage a sliding element on the first part. In the construction shown both the stem 5 of the ball and the stem 5<1> of the socket are disposed longitudinally and non-rotatably in supports 2, 2<1> on the vehicles, the socket comprising a relatively fixed hemispherical part 4 and a universally movable part spherical part 7. An extension 15 of the part 7 is internally threaded to engage a cylindrical nut 16 which is slidable in keyways 18 on the socket part 4, the coupling being made and tightened by rotation of the part 7 which, for this purpose, may be provided with handles 20 or with teeth 21 engageable by teeth 23 on an operating lever 22. Preferably the ball is formed of two portions 8, 11 pressed into close contact with the socket by means of an intermediate spring washer or equivalent 13. Modifications are described in which the socket part 7 is adapted to engage internal threads on the connecting nut, and in which the nut is slidably mounted on the part 7, both the latter element and the nut being rotated when coupling or uncoupling is being effected. External springs 19 are provided to damp shocks arising when two vehicles are brought together to effect a coupling. Specification 439,326 is referred to.

Abstract: 790,763. Hats. OLDHAM & FOGG, Ltd. Feb. 23, 1955 [Nov. 25, 1953], No. 32661/53. Class 63 Crease-resisting and shape-retaining properties are provided in a felt hat or part thereof, e.g. the brim by applying and bonding to the felt a continuous top film of flexible material, e.g. rubber, natural or synthetic. The film is not so substantial that the identity of the fibres is lost to an extent that the surface no longer has a fibrous appearance. In one example described the inside of fhe crown and under brim was given an extra close finish with very fine sandpaper and the hat subjected to hot pressing in a metal mould. These parts were then brushed with a rubber emulsion of 25 per cent pure rubber and 2 per cent of a silicone emulsion in water. After drying and further hot pressing, the hat was finished in normal manner. The hat was waterproof from outside and greaseproof from inside. The rubber emulsion may be replaced by a water emulsion of plasticized polyvinyl acetate and the emulsion may be tinted to give a different shade or colour to the treated parts of the hat, e.g. inside the crown and both sides of the brim. The material may be sprayed on the hat and then brushed or may be applied by rollers in a hat-proofing machine. Specification 640,881 is referred to.

Title: Device for correcting the inclination of motor vehicle head lights according to the trim of the vehicle
IPC: B60Q1/10
Filed: 1973-07-09
Abstract: 1402245 Cams SOC ANON DBA 9 July 1973 [11 Aug 1972] 32676/73 Heading F2K [Also in Division F4] An arrangement for adjusting the inclination of motor vehicle headlights about a horizontal axis in response to a variation in the vehicle trim comprises a one-way connector mounted between the headlights and a control means, wherein the connector transmits to the headlights the actions of the control means responding to variations in the vehicle trim but it does not transmit to the control means reactions of the headlights due, for example, to wind resistance when the vehicle is travelling at high speed. As shown, the headlight 1 is adjusted about a horizontal transverse axis 11 by the action of piston 9 of the hydraulic or pneumatic control device 10. A transverse pin 22 at the end of piston 9 is guided in straight horizontal slots 25 in the parallel plates 5, 6 of a yoke 4 which is mounted on a retainer 2 attached to the vehicle bodywork. A second yoke 13 is rotatably mounted by a rod 18 about a horizontal axis between the plates 5, 6 with the transverse piston pin 22 engaging in curved slots 21 of respective sides 19, 20 of the yoke 13. The base 17 of the yoke 13 is attached by a ball-and-socket joint 16 to a threaded rod 12 mounted by a further ball joint in a nut 14 attached to one side of the headlight 1. The threaded rod 12 provides for initial adjustment of the headlight. It is arranged that the general direction of the slots 21 in the yoke 13 are perpendicular to the reaction force transmitted from the headlight and are slightly inclined to the piston-rod axis, Fig. 4 (not shown), so that the pin 22 frictionally engages the slots 21 such that the component of the frictional force parallel to the piston axis is greater than the reaction force acting on the piston-rod. A variation in which the yokes forming part of the connection means are of an alternative construction, disposition and arrangement is described with reference to Fig. 3 (not shown).
