Abstract: 939,302. Disc brakes. DUNLOP RUBBER CO. Ltd. March 11, 1960 [April 21, 1959], No. 13502/59. Class 103 (1). A disc brake comprises a non-rotatable baseplate 112 slotted at 113 and completely surrounding a disc 111 on a chord thereof, axially opposed friction pad assemblies 114 being situated on opposite sides of the disc, and means for imparting sliding movement to the assemblies along guides 112b secured to, or integral with, plate 112, to bring them into engagement with the disc 111. A stiff shell-lever 119 has a projection 119a engaging a ridge 118 on pressureplate 115 and is connected by two tie-rods 120 and pins 119b to pressure-plate 116, the plates 115, 116 being pivoted to the edges of plate 112. A cylinder 124 fixed to lever 119 has a piston 123, 123a, engaging plate 115, a return spring being attached to lever 119 and a flange 126 on base-plate 112. A stop-rod 127 prevents lever 119 rotating so far that piston 123 leaves cylinder 124. Centralizing springs 128 between pressure plates 115, 116 and the associated backing-plate prevent unilateral action of wearcompensating devices 117. The lever 119 may be rotated by a linkage connected to cylinder 124. The mounting of pressure plates 115, 116 on plate 112 comprises a bolt 129, Fig. 5, passing through bores 132, 133 in projection 115a and engaged in plate 112, a spacer 113 surrounds bolt 129 and a spring 130 urges the plates apart. The loose fit of spacer 131 in bores 132, 133 and the greater length of spacer 131 over the thickness of projection 115a permits limited angular movement of the plate 115 or 116. Inward forces on plates 115, 116 from the rotation of lever 119 about ridge 118 by the piston-andcylinder 123, 124, is transmitted to the pad assemblies through devices 117. These devices comprise a threaded member 137, Fig. 6, having a spigot 136 in a hole 135 in backing-plate 134, a peg 134b locating the pad on plate 134. The member 137 is closed by a disc 139 having a recessed dowel 140; a cylinder 141 has a blind bore 142 with a keyway 143 for a pip 149 on a disc 148 which has a recessed dowel 150; a rounded cylinder portion 145 engages plates 115 or 116. A spring 151 with its ends in the dowel recesses is torsioned when cylinder 141 is screwed into member 137 by a screw-driver in extension 146, 147. On brake release, pad retractors, not shown, withdraw the pads a predetermined distance from the disc, the increasing distance between backing-plates 134 and the pressure-plates 115, 116 due to wear being constantly taken up by the unwinding of cylinder 141 from member 137 by spring 151. Specifications 881,423 and 939,301 are referred to.

Abstract: 1,083,019. Retractive switches. H. A. L. DE HAAS. March 28, 1966 [March 26, 1965], No. 13518/66. Heading H2B. A traffic pad comprising an elongated resiliently compressible hollow body 1 includes a flexible cable 18 anchored at 20, passage of a vehicle over the pad causing longitudinal displacement of the free end of the cable 18 to actuate a switch such as microswitch 29. A similar cable 24 attached to the same crosspiece 25 as cable 18 compensates for variations in ambient temperature. A spring 27 tensions both cables. The switch actuated by movement of cable 18 may alternatively comprise two contact arms (28<SP>1</SP>), (36), (Fig. 3, not shown), which move apart on displacement of the upper cable. The switch may also comprise a spring- urged plunger contact (51) engaging a plunger contact (39) formed on the end of cable 18 (Fig. 4, not shown). Sudden movement of cable 18 separates the plunger contacts because movement of the contact (51) in a direction to follow contact (39) is retarded hydraulically. Slow movement of cable 18 in response to temperature changes, however, results in spring (52) to maintaining plunger contact (51) against contact (39).

Abstract: 290,444. Arnold, C., (Standard Development Co.). May 21, 1927. Lead and tin alkyl compounds.-Alkyl compounds of metals of the second sub-group of the fourth group of the periodic table are produced by alloying the metal with an alkali metal, treating the subdivided alloy in a closed reaction vessel with an alkylating agent dissolved in a liquid hydrocarbon and separating the resulting metal alky compounds, for example by extraction with a solvent, or by steam distillation after removal of the hydrocarbon solvent if the latter be easily volatile. The vessel, which may be equipped with heating and cooling jackets or coils and a stirring device or grinding and agitating balls need only be warmed at the commencement of the reaction. In an example a sodium-lead alloy and naphtha are introduced into a reaction vessel and ethyl chloride is gradually added. Lead tetraethyl is produced and is separated. Other petroleum distillates such as white oil and kerosene and benzenoid hydrocarbons such as benzene, toluene and the xylenes are stated to be suitable solvents. The process, which is particularly suitable for producing tin alkyl compounds as well as those of lead, may be facilitated by using catalysts as described in Specification 214.221. Ethyl bromide is mentioned as another alkylating agent.
