Patent GB-1143559-A (GB)
IPC: B60T8/171
Abstract: 1,143,559. Measuring acceleration electrically. WESTINGHOUSE BREMSEN UND APPARATEBAU G.m.b.H. April 24, 1968 (April 28, 1967], No.19368/68. Heading G1N. Acceleration responsive apparatus comprises a magnetizable strip relatively movable along a path with respect to a magnetizing device and a pick-up device, means for exciting the magnetizing device at a fixed frequency to produce an alternating magnetization along the length of the magnetizable strip, and means for comparing the frequency of the signal from the pick-up device with the frequency fed to the magnetizing device to produce an output signal if the frequencies differ by more than a predetermined amount due to acceleration. The invention is particularly useful for detecting skidding of the driving wheels of a railway locomotive, the magnetizable strip being arranged around the periphery of a driving wheel or a wheel driven in accordance with the driving wheel. As shown in Fig, 3, two pick-up devices 4', 4a are provided, one each side of the magnetizing device 3', one being selected for use depending on the direction of travel of the locomotive. A D.C. or high frequency A.C. wiping unit 2' is provided. The sensitivity of an amplifier 15 in the output circuit of the frequency discriminator 7' is controlled in dependence on the speed of the wheel 1' which is measured by a pick-up 20 co-operating with permanent magnets 19 on the wheel. The output of the amplifier 15 is fed to a regulating member 18 to reduce the output of the drive machine and to actuate a sand spraying device. The invention is responsive to negative as well as positive accelerations and may be used to monitor wheel slipping during braking. Other applications include measuring the acceleration of a vehicle moving on magnetizable rails and measuring the acceleration of a magnetizable tape.

Abstract: 1,257,708. Abrasive tools. F. L. & J. C. CODMAN CO. 31 Jan., 1969, No. 5467/69. Heading B3D. [Also in Divisions C4-C5] An abrasive element 10, Fig. 1, comprises a shell 12, substantially surrounding an abrasive filler 14 comprising abrasive grains 16 and a resilient bonding agent 18, the shell having at least one opening exposing the filler and comprising material that is destructible with wearing down of the abrasive filler. The shell may be of paper, cloth, woven fibre-glass, or a fluorocarbon or polyester plastics film. The abrasive grains may be of 30-220 grit size and of silicon carbide or aluminium oxide. The bonding agent may be polyurethane elastomer and/or foamed polyurethane. The shell is preferably a folded or twisted tube e.g. of square or circular crosssection, open at at least one end, but may be a flat or pleated slab, e.g. slab 20, Fig. 6. A plurality of the elements may be secured radially to a hub 22 or 28, Fig. 6, to form an abrasive member and the opening(s) in the shells may be positioned so that the abrasive filler 14 is exposed over the face or the edge of such member.

Abstract: 1,259,290. Change speed gear control. SUNDSTRAND CORP. 23 Dec., 1968 [27 Dec., 1967], No. 5243/71. Divided out of 1,259,289. Heading F2D. This Specification has the same disclosure as Specification 1,259,289 but the claims relate to delaying engagement of the clutch (55), Fig. 2 (not shown), until the elements thereof are synchronized. This preferably involves a valve 180 comprising coaxial members 189, 190 rotating with the parts to be synchronized, and between them a member 191 with a lost motion connection 192 to the member 190, and a frictional connection 199 to the member 189. When the direction of relative motion between members 189 and 190 changes the member 191 moves relative to the member 190 changing the connection of a conduit 185 between a pressurized line 327 and a vented line 195. Thus when changing from low ratio to high ratio in the gearing disclosed, line 185 becomes pressurized arresting movement of the swash-plate (115) via lines (187, 177, 178). A resulting pressure increase in a line (327a) moves the lockout valve (134) supplying fluid from line 185 via line (188) to the shift valve (132) initiating the ratio change.

Abstract: 1,264,676. Boron nitride. VARIAN ASSOCIATES. 6 May, 1969 [31 May, 1968], No. 23125/69. Heading C1A. Isotropic boron nitride is deposited on to a substrate member by reacting diborane gas and ammonia gas to form an intermediate gaseous reaction product, and causing this product to flow at subatmospheric pressure across the substrate heated to a temperature over 1200 C., thereby causing the intermediate product to decompose with attendant deposition of boron nitride of at least 0À010 inch thickness. Preferably, the diborane gas is mixed with an inert carrier gas (e.g. nitrogen) to a concentration of 50,000 p.p.m. of diborane; the temperature for the diborane/ammonia reaction should be between 200 and 300 C.; the pressure in the deposition chamber should be less than 0À3, preferably 0À001, atmospheres; and the substrate member is tubular or of rectangular cross-section and is made of molybdenum, tungsten or tantalum. A stream of inert gas may be directed round the stream of intermediate products so that the latter is directed through the interior of the substrate to deposit the boron nitride on the interior surface; and the ammonia should be reacted with diborane in molar ratios greater than 2 to 1 so that deposition of free boron with the boron nitride is prevented. The process provides deposits preferably greater than 0À125 inch thick of boron nitride of specific gravity 1À35 to 1À65.
