Abstract: 448,049. Gauging-apparatus. BROWN, G. W., Ash Grove, Manor Road, Borrowash, near Derby. Dec. 17, 1934, No. 36094. [Class 106 (ii)] Comprises a calliper gauge having two members for engagement with a rail or other object, the movable gauging members being so interconnected with one another and with a pointer that the latter is adapted to read weights, moments of inertia &c. The invention is described as applied to measuring a rail and indicating the weight per unit length which depend on the wear of the top flange and general wastage due to corrosion &c. A case. or housing 10 is provided with lugs 11 for securing a cover plate 12 which is cut away and fitted with a hinged mirror 14 by which reversed scales 13-shown positive for convenience-may be read. A projection on the casing is pushed under the rail 18 which is engaged by the bottom flange against a flat 16<a> and against lugs 21a, 21b at the side. A sliding rod 19 has an upstanding projection 20 which is adapted to engage the other side of the bottom flange. The rod 19 is guided by members 22, 23 and has fixed to it a plate 25 guided on rod 24. A disc 26 rotatably mounted on the case 10 has passing through it a lever 27 one end of the lever slidably fitting within a disc 28 fixed on the plate 25, the other end being slidably fitted with a disc 29 on a plate 30 which is adapted to slide on guide rods 31.

Abstract: Non-caking materials for use in fluorescent screens for cathode-ray tubes or for transmitting or intensifying screens for X-ray work consist of zinc sulphide, cadmium sulphide, zinc-cadmium sulphide, or zinc-cadmium-manganese sulphide prepared by coating the grains of the material as a result of a washing operation with an amorphous or fine crystalline deposit of aluminium hydroxide, zinc sulphide, zinc oxide, or zinc oxychloride.  The fluorescent material may be washed with a solution of an aluminium salt and then with ammonia solution or first with a solution of a zinc salt, e.g. zinc chloride, and then with water forming zinc oxychloride or with sulphuretted hydrogen water forming zinc sulphide.  The deposition may be carried out before or after the usual heating process but if the deposit is formed before heating, care must be taken to avoid volatilization during heating.  The Specification as open to inspection under Sect. 91 describes also the use of other deposited substances especially alkaline earth carbonates and coloured substances, the colour influencing the final colour of the screen emission.  This subject-matter does not appear in the Specification as accepted.

C., 88, Chancery Lane, London.-(Globe Machinery & Supply Co. ; 205, Court Avenue, Des Moines, Iowa, U.S.A.) Nov. 29, 1929, No. 36725. [Class 69 (ii).] In a rotary vehicle hoist of the type having a hydraulic cylinder mounted vertically in the ground, a liquid-containing reservoir 18, Fig. 5, is disposed beneath the cylinder 14 and a pipe 22 opening in the bottom of the cylinder passes to the bottom of the reservoir, whilst means are provided for forcing fluid 8 (e.g. air) into the upper part of the reservoir to displace the liquid 20 into the cylinder. The cylinder contains a piston 40 with a hollow piston-rod 16 carrying at its upper end a head 64 to which longitudinal runways 68 are attached by means of transverse supporting bars 66. On applying air pressure to the reservoir 18 the hoist rises until the collar 52 on the pistonrod, Fig. 14, engages with a flange 48 on the cylinder. When this occurs the gauge 34, which registers the pressure of the air, gives an increased reading. The hoist may be retained at any convenient height by thrusting a pin into one of a number of holes 58 in the piston-rod. For retaining the hoist at its highest point an automatic latch is provided which consists of two slide bars 130, pivoted to links 132 connected at their upper ends by springs 136. When the hoist is raised the slide bars snap into the position shown in full lines in Fig. 14, thus sustaining the hoist. To lower, the hoist is somewhat raised to relieve the pressure on the slide bars, which are then partially withdrawn by turning the T-handle 156 thereby lifting wedge 142 to the position shown in dotted lines and forcing the pivots 134 apart. As the hoist descends the slide bars 130 are pressed inwardly by flange 48 and pivots 134 are further separated so that the wedge 142 drops into its original position -reset for the next hoisting.
