The vials are inserted through holes in the frame and are clamped in position by the supports. Adhesive is applied to the vials and the holder is then inserted in the opening in the level, ribs 38 preventing relative movement between the vial holder and the level. The positions of the vials are accurately adjusted before the adhesive cures to permanently secure them. The holder is formed of a plastics material. In modifications, caps with curved or tapered surfaces are secured to the ends of the vials. These surfaces bear on the seats and amplify the adjustment of the vials.

In a railway track having its rails inwardly canted, e.g. by sleeper plates 22, the cant angles of the outer rail 12 at curves is increased relatively to that of the inner-curve rail 11 to reduce rail wear and failure. The increase may be effected (a) by shaping the sleeper surface 13' as shown; or (b) by inserting tapered shims or pads under the plates 22; or (c) by using modified plates 22; or (d) by using modified rails. Where the cant angle of the straight and inner-curve rails is 1 in 40, the increase required is generally 245', but the increase required for any particular track may be determined experimentally by tracing the contour of worn outer-curve rails.

Abstract: 1,228,101. Metal clad switchgear; gas blast switches. "COQ" N.V. 16 April, 1969 [22 April, 1968], No. 19496/69. Heading H1N. A metal clad, gas filled switchgear has a high pressure compartment 2 containing arc extinguishing SF 6  gas and a low pressure compartment 14 containing insulating SF 6  gas and has a gas control system which adjusts the density of gas in the two compartments such that the pressure difference between the two compartments is maintained substantially constant and the density in the low pressure compartment is maintained substantially constant. As shown the high pressure compartment 2 which contains a multibreak gas blast switch 3 is located inside the low pressure compartment 14 which also contains a series isolating switch 4; earthing switch 10; spark gap 11; duplicate bus-bar selectors 5, 6; and current transformers 12, 13. The gas blast vents into a chamber 15 from where it is returned to the compartment 14 through filters 38 and non-return valves. The pressures in the two compartments are applied to opposite sides of a differential pressure switch 48. If the pressure difference is too high a contact 50 is closed and a solenoid valve 34 opened to allow gas to leak from one chamber to the other. If the difference is too small another contact 49 is closed to energize a compressor 36 to pump gas from the low pressure to the high pressure compartment. The density of gas in the low pressure compartment 14 is sensed by a switch 45; if too low a contact 46 energizes a valve 28 to introduce more gas from a bottle 30; if too high a contact 47 energizes a valve 31 to vent some gas to the atmosphere. To avoid unnecessary loss of gas valve 31 is energized by way of a contact 53 of switch 48 so that valve 31 is not operated while the pressure difference is low, e.g. during a switching operation. If due to low temperature some gas condenses in the high pressure compartment 2 it flows to a chamber 44 and a float switch 52 energizes a heater 43 to revapourize it. In a modification (Fig. 3, not shown) to avoid loss of gas to the atmosphere low and high pressure gas storage tanks (54, 60) are connected to compartment 14 and gas is recirculated between them by a second compressor (59). In this case chamber 15 feeds the filtered gas to the low pressure tank (54) and valve 48 senses the difference between the high pressure compartment 2 and chamber 15 whose pressure rises more rapidly and therefore causes a quicker response during an interruption. In a further modification (Fig. 4, not shown) the storage tanks (54, 60) and compressor (59) are shared by a plurality of switchgear assemblies.

In Example 2 component (A) is prepared from maleic anhydride and polybutadiene in the presence of copper naphthenate, and xylene. It is diluted with diacetone alcohol, hydrolysed with water and then treated with a copolymer of allyl alcohol and styrene. Component (B) is prepared from formaldehyde and 4, 4-bis (4-hydroxyphenyl) pentanoic acid in the presence of triethylamine. The composition also comprises ethylene glycol monoethyl ether, methylate melamine formaldehyde resin, diethylene glycol monoethyl ether Fe 2 O 3  and triethylamine. It is dipspray- or flow-coated on to steel.

Abstract: 1,230,710. Compression moulding resin contained in a bag. G. KONIG. 24 Sept., 1969 [28 Sept., 1968], No. 46927/69. Heading B5A. Synthetic resin articles are formed by filling a preformed moulding bag with the resin moulding composition and any of filling and insulating materials and compression moulding and curing the composition in the bag. The bag is preferably evacuated before the moulding step and the contents may be maintained under vacuum during the pressing. The bag may contain reinforcement or prefabricated parts such as heating, cooling or illuminating components. The bag may be made of extensible material and may be smaller than the final product so that wrinkles are prevented. It may be made of a release material, it may remain on the surface of the mould or it may comprise a two-ply sheet, with an outer ply which can be peeled off and an inner ply which adheres to the moulding. The bag may be vacuum formed from a sheet before moulding.

Abstract: 1,231,014. Trichlorotrityl chloride complexes. FARBWERKE HOECHST A.G. 22 July, 1968 [22 July, 1967], No. 34764/68. Heading C2C. [Also in Division C4] Complex aluminium or iron compounds of p trichlorotrityl chloride are prepared by reacting 4-chlorobenzotrihalides with an excess of chlorobenzene at about 50-60‹ C. in the presence of approximately the theoretical amount of aluminium chloride or iron (III) chloride and separating the metal complex which crystallizes.
