Title: Improvements in and relating to tools for detaching and attaching the tyres of motoror other vehicles
IPC: B60C25/04
Filed: 1920-12-29
Abstract: 177,600. Mote, F. F. Dec. 29, 1920. Tyres, elastic, and tyre covers, tools for removing and replacing.-A tool for manipulating tyres shown in Fig, 2 comprises two ribbed concaved rollers d which track on the rim and a third roller or rollers s. The rollers are driven by gearing which is mounted in the casing a and operated by a reciprocating hand-lever k. In the form shown in Figs 4 and 5. the rollers 3 are supported on a pivoted yoke-piece 4 fitted with a cam 6. A grooved roller 8 carried by the lever k normally en. gages in a slot 7 in the cam 6 to lock the yoke 4 against tilting about its pivot 5. By moving the lever k beyond its normal travel, the roller 8 leaves the slot 7 and by moving the pin 10 to the other end of the slot 11 in the lever k, the roller 8 rides up the cam 6 in the next reciprocation of the handle, allowing the yoke 4 to tilt. By this means additional motion is given to the tool when it is near the end of its movement and alose to the hub and spokes. In a form shown in Fig. 6, anchors 28 to engage the rim and pusher-pieces 29 to force the tyre away from the rim, are provided. These devices are pivotally mounted on the tool itself.

Abstract: 897,211. Tyre presses. McNEIL MACHINE & ENGINEERING CO. Oct. 27, 1960 [Nov. 9, 1959], No. 36889/60. Class 87(2). A tyre press for shaping and airing unvulcanized tyre bands comprises a boom 30 pivoted about a vertical shaft 35 and carrying a vertically reciprocable mandrel 31 having expansible elements 105 for loading a tyre band into the mould, which comprises separable sections 20, 21. To load and position the unvulcanized tyre band a pneumatic cylinder device 43 is actuated to rotate the boom 30, Fig. 1, to the front of the press where it actuates switch 50B. The mandrel 31 is then raised by introducing compressed air into a cylinder 65, Fig. 6, and above a fixed piston 58 within the mandrel 31 and in its upper position actuates a switch 132. An uncured type band B is then supported on a platform 32 and when in position actuates a switch 150. On closure of the switches 50B, 132 and 150 which are in an electric control system for the pneumatic device the mandrel 31 is lowered, Fig. 2, by the exhaustion of cylinder 65. Compressed air is then introduced into the cylinder 65 below a movable piston 98, Fig. 6, thus moving shaft 95 and links 111, 116 to expand the mandrel elements 105 and actuate a further switch 128, signalling that the elements 105 are engaging the tyre band B. The mandrel and tyre is raised and boom 30 rotated into the press by the cylinder device 43, a switch 50B signalling correct positioning, whereupon the mandrel 31 is partially lowered to a position predetermined by switch 132, and the elements 105 are contracted by exhausting cylinder 65 below the piston 98, bringing the tyre band into contact with tyre band forming mechanism of the conventional curing bag type. Specifications 786,347 and 786,348 are referred to.

Patent GB-915593-A (GB)
Title: A method of forming an electrical contact on a semiconductor
IPC: F16B5/06
Filed: 1960-10-27
Abstract: A method of making an ohmic contact to a semi-conductor body comprises evaporating thereon a first metal layer capable of alloying with the semi-conductor and an overlying layer of a second metal capable of alloying with the first metal only at a temperature higher than that at which the latter will alloy with the semi-conductor, heating to alloy the first layer with the semi-conductor, and then attaching a low-melting metal to the second metal by heating at a lower temperature.  In an embodiment phosphorous is first diffused into the surface of the N-type silicon wafer to form a heavily doped surface zone.  The diffusion is effected by heating the wafer for 1/2 hour at 1100-1300 DEG  C. in a flow of dry nitrogen which has passed over a phosphorus pentoxide source at 240 DEG  C.  Gold and antimony are then simultaneously evaporated over the treated surface to give a layer containing 0.5% by weight antimony about 5m  thick.  After evaporation of a superposed silver layer about 5m  thick the gold layer is alloyed to the wafer by heating at 370-500 DEG  C. Subsequently a layer of tin or lead on a copper header is attached to the silver layer by heating to 250 DEG  C.  The phosphorus diffusion step may be omitted and phosphorus, arsenic, or bismuth used in place of antimony in the first layer.  To form a similar ohmic contact to a P-type wafer the first layer should contain boron, aluminium, gallium, indium or tellurium.

Abstract: 787,786. Laminates. UNITED STATES RUBBER CO. Dec. 28, 1955 [March 21, 1955], No. 37100/55. Class 140. A laminated cushioning material comprises a reinforcing lamina of universally stretchable, water-repellent paper and a cushioning lamina of elastic sponge rubber. The paper, for example Kraft paper, may be first made universally stretchable by wrinkling it, across its length, for example, by creping, and corrugating it along its length by passing it through grooved rolls, the amount of stretch being not less than 5 per cent in all directions. The paper may be waterproofed by impregnating with paraffin wax or other water-insoluble wax which is compatible with sponge rubber, e.g. microcrystalline or carnauba wax, the melting point of the wax being lower than the vulcanizing temperature of the rubber. The method of laminating may be as indicated in Fig. 3, wherein the rubber mix 15, containing a blowing agent, is calendered at rolls 16 to the form of a sheet 17 which passes on to a belt 19 and so under a belt 24 where it is met by a sheet of the treated paper 21 coming from roll 22. The sheets are carried into the press 20 which comprises a lower heating platen 25 and upper heating platens 26 which are adjustably suspended from arms 28 by weights 27. U.S.A. Specification 2,096,338 is referred to.

Title: Crane Radius Indicator or Crane Safe-Load Indicator Radius Compensating Device
Inventor: AITKEN ROBERT LOUDON
IPC: B66C23/90
Filed: 1967-08-15
Abstract: 1,183,190. Safe-load indicators for cranes with telesopic jibs. B. & A. ENG. CO. Ltd. 12 Aug.. 1968 [15 Aug., 1967], No. 37555/67. Heading B8B. A crane radius indicator device or a crane safe-load indicator radius compensating device for a crane having an extensible jib comprises, as shown in Fig. 2, a stationary casing 1 secured to the crane superstructure A adjacent the jib pivot axis 2. An indicator member 3, mounted on parallel links 4, 5 pivoted to the casing 1, is movable along a support formed by a drive screw 11 driven through bevel gears 12, 14 actuated by a spring drum 10 rotated by a cable 9 attached to the jib peak. A follower in the form of a trunnion nut 15 is thus moved along the screw 11 in proportion to the effective length of the jib. The screw 11 is arranged radially in relation to the jib pivot axis 2 and pivots about that axis. The nut 15 runs in a vertical slot 8 in the indicator member, and the horizontal distance of the slot 8 relative to the axis 2 is proportional to the operating radius of the crane (considered as the product of the effective length of the jib and the cosine of the jib angle). The slot 8 has an additional terminal portion 18 which is not aligned with the main portion, so that when the jib as fully raised the indicated radius exceeds the true radius because the limiting factor is not the overturning moment of the load, but the strength of the jib. The indicator member 3 is linked with an indicator pointer (not shown) through lever 16, forming an extension of parallel link 5. The lever may additionally, or alternatively, be linked with a safeload indicator such as that described in Specification 723,070 so as to compensate it for change of crane operating radius. In the alternative construction shown in Fig. 4, support screw 11<SP>1</SP> and the ,indicator member 3<SP>1</SP> are mounted in a common casing for support by the jib. Lever 18<SP>1</SP> is connected by a link to form a parallel motion linkage with a similar lever (not shown) coaxial with the jib pivot so that lever 18<SP>1</SP> remains at a fixed inclination to the ground as the jib luffs. Luffing of the jib thus causes a tilting movement of the screw 11<SP>1</SP> in relation to casing 1<SP>1</SP> and there is produced a relative movement between screw 11<SP>1</SP> and indicator member 3<SP>1</SP> corresponding to that between screw 11 and indicator member 3 as described above.
