Title: A Method and Apparatus for Measuring Tyre Pressures
Inventor: RAFFAELLI GIULIO
IPC: G01L17/00
Filed: 1967-03-21
Abstract: 1,185,911. Measuring tyre pressures. G. RAFFAELLI. March 21, 1967 [March 26, 1966; June 3, 1966; Oct.12, 1966; Jan. 19, 1967], No. 13072/67. Headings G1L and G1N. The increase in pressure in a tyre due to heating in use, is compensated for in measuring the tyre pressure by automatically correcting the pressure gauge indicator by a factor, determined electrically, proportional to the difference between the tyre air and ambient temperatures. As shown, Fig. 1, the two temperatures are measured by thermistors 25, 26 connected in a bridge circuit with a pressuresensitive resistor 29. Servomotor 62 automatically rebalances the bridge by varying resistor 28, simultaneously moving the scale 30, Fig. 3 of the pressure gauge. The latter comprises two tubes 41 standing in mercury bulbs 42, open to the atmosphere on one side via tube 73<SP>1</SP>, and supplied with the tyre pressure on the other side via tube 73. The scale 30 indicating the difference in heights of the mercury columns is movable vertically via worm gear 31-33 by servomotor 62, which simultaneously adjusts resistor 28. The gauge carries ambient temperature sensor 26 at the top, and pressure sensor 29 in tube 73. The tyre air temperature sensor 25 is located in an air pocket near the nozzle of an air pressure gun, arranged to receive air from the tyre and not air for the tyre. Other types of pressure gauges are described. If the pressure gauge has a logarithmic scale the pressure sensitive resistor 29 may be replaced by a fixed resistor.

Title: Improvement in method of making elastic fabrics
IPC: F16B12/02
Filed: 1952-05-23
Abstract: 702,515. Elastic fabrics. UNITED STATES RUBBER CO. May 23, 1952 [June 28, 1951], No. 13091/52. Class 140 In the method of making an elastic fabric, as described in Specification 648,644, wherein a woven or. knitted fabric of interlocked yarns having 10-40 per cent. of heat-shrinkable synthetic resinous filaments associated therewith, is heated to cause the filaments to contract the fabric and hold it contracted while it is coated with rubber and the rubber is cured, the filaments are then rendered inactive to hold the fabric contracted by breaking them into short lengths by combined action of heat and tension. The coated fabric may be stretched in the direction of the filaments, which may be included in the warp and/or weft or may be mixed as staples with say cotton fibres to form the yarns. The shrunk rubber backed fabric 10<1> is drawn from roll 13 round system of rolls 17, 16, 18, of which 16 is power driven, into oven 20, where it passes round steam heated rotatable drum 22. The fabric 10<1> is withdrawn from the oven round roll system 27, 26, 28, of which 26 is driven at a higher speed than roll 16 to impart longitudinal stretch to the fabric while passing through the oven. With the preferred filaments consisting largely of polyvinyl chloride the fabric should be heated to above 275‹ F. The fabric is then passed to a tentering apparatus, Figs. 4, 5 (not shown) whereon transverse stretch is imparted while passing through an oven also heated to above 275‹ F. It is stated that in some cases the transverse stretching with heating on a tentering apparatus, as the fabric is also prevented from contracting longitudinally, may alone be sufficient to break both longitudinal and transverse restraining filaments.

Title: Flash butt welding machines
IPC: B23K11/04
Filed: 1962-04-06
Abstract: 928,268. Welding by pressure. H. A. SCHLATTER A.G. April 6, 1962 [April 7, 1961], No. 13347/62. Class 83 (4). A flash-butt welding machine having, for each workpiece, one pair of vertical clamping jaws, at least one pair of contact jaws, and two pairs of horizontal clamping jaws, is characterized in that the contact jaws and horizontal clamping jaws have lower clamping pressures than the vertical clamping jaws and, for welding lighter workpieces, the contact jaws also act as vertical clamps, the vertical clamping jaws being retracted in this case. Referring to Fig. 1, two railway rails 44 and 45 are mounted for butt welding at position X. The first rail 44 is clamped horizontally by two pairs of clamps 6a, 8a and vertically by a single pair of clamps, only the upper one 3a being shown. The contact jaws 9a, 9b also exert a clamping pressure. The contact and clamping arrangement for the second rail 45 is identical, the entire assembly, however, being carried on slideways. All the clamps and contacts and the slide motivation is by means of fluid-operated pistons and cylinders. Referring to Fig. 3, which shows the clamping and contact arrangements for the rail 44, the pistons 4a, 6a and 8a have larger working areas than their opposite units 4b, 6b and 8b. In clamping heavy workpieces, valves 26, 27, 28, 29 and 30 are opened to supply pressure fluid to the working side of the horizontal; vertical and contact pistons, and to connect their return sides to the return pipe 25. The piston movement in the larger cylinder of each pair is mechanically linked to valves 31, 32 and 33 through adjustable stop screws 40, 37 and 46 respectively. The valves 31, 32, 33 progressively open the working volume of the larger pistons of the pairs to the return pipe 25, thus gradually reducing the pressure in the larger cylinders of the pairs until equilibrium is attained with the constant thrust of the smaller cylinders of the pairs. Thus the position of the clamped rail is automatically adjusted. When welding workpieces which will not withstand the vertical clamping pressure of cylinders 4a, 4b, valves 27, 28 are set to retain the vertical clamps in their withdrawn position, and a valve 43 is opened to connect the working spaces of cylinders 10a and 10a<SP>1</SP> with each other, thus causing the contact jaw 9a to act with greater force than 9b. This out of balance is used as before to effect positive vertical positioning of the rail through a valve 34 and adjusting screw 47. It is possible to use each of the two clamping procedures described simultaneously in the welding of a heavy workpiece to a light workpiece. Specification 817,166 is referred to.
