Abstract: 1,142,672. Endless conveyers. CHANCE BROS Ltd. 9 June, 1966 [21 June, 1965], No. 26169/65. Heading B8A. [Also in Division G1] In apparatus for sorting glass tubes from a selection of lengths those which are of a predetermined length, the tubes are conveyed in grooves 2 of a conveyer 1 between a working face 9 and an inspection face 10, the distance apart of the faces 9, 10 being the required length of tube. Tubes which are of a greater length are inclined at one end by a sloping edge 12, and those of the correct length or of a shorter length pass straight along. Spring sheet member 14 prevents those of only a slight variation in length from falling back on to the conveyer. Subsequently, all the over-long tubes are moved laterally by an angled face 16 so that as they fall back on to the conveyer their ends extend beyond the ends of the remainder, under a trip wire 17. The trip wire 17 bends downwardly and causes the over-long tubes to tilt downwards into a shoot 18. Further along the conveyer system, a further pair of surfaces 21, 22 are provided, the distance between the surfaces being just less than the required distance, so that those of the required length are raised at one end. The other tubes are deflected away into a shoot 26 by a trip wire 25. A pivoted arm rests on the tubes as they pass block 20 to rotate the tubes whilst they pass an inspection edge for determining whether the end face of the tube has an irregular edge, tubes having an irregular end surface falling off the inspection edge.

[Also in Groups XXXVII and XXXIX] In an impulse counting device of the type in which impulses fed to a common magnetic circuit operate a succession of armatures which thereupon remain operated, each armature controls a pair of springs whose contact-carrying ends are staggered in opposite directions, the contact sets so formed comprising contacts carried by springs controlled by adjacent armatures. Fig. 2 illustrates the spring sets controlled by armatures 5 and the formation of a contact set in the middle position using a righthand upper spring and a left-hand lower spring. Some springs have been omitted at the sides for a clearer illustration of the shape of the springs. As shown, Fig. 3b, an initial break contact set 100a, 100b is provided with a fixed lower spring 100b. This contact set is opened by the raising of the spring 100a by the operation of the first armature 501 on receipt of the first impulse and remains open thereafter as an off-normal indication. Operation of the first armature also raises spring 101b to make connection with contact spring 101a. On the next impulse armature 502 operates and raises spring 101a which is thus disconnected from spring 101b, and spring 102b is raised into contact with spring 102a and so on. The last upper spring 110a is fixed.

Abstract: 706,732. Photo-electric cells. CLARK, D. M Nov. 13, 1951, No. 26547/51. Class 39(1) A photo-electric tube for use in sound reproduction from a coloured track which absorbs a selected intermediate range of the visible spectrum comprises a cathode sensitive to the said range and to the two adjacent ranges and an envelope for the cathode coloured to absorb the said adjacent ranges. The sound track can be in green absorbing magenta dye and the cathode sensitive to the green range and to adjacent ranges towards the blue and yellow, and the envelope so coloured as to absorb the adjacent blue and yellow ranges. The photo-electric tube P, Fig. 2, has a cathode 11 coated with a caesiumantimony alloy and an envelope 10 of green glass or covered with a green filter layer. The envelope 10 can be made of the customary soft glass containing about 14 per cent Na 2 O and from 5 to 6 per cent CaO, to which have been added copper and chromium oxides in amounts up to about 1 per cent. The admixture limits the effective transmission of the glass essentially to the region from 500 to 540 mÁ. Alternatively the envelope can be sprayed with or dipped into a nitro-cellulose lacquer solution containing 1 per cent each by weight of the dyes Guinea Green B (C.I. 666) and Quinoline Yellow Spirit Soluble (C.I. 800). The envelope can be filled with argon at a pressure of from 0.1 to 10 mms. of mercury which is stated to render the tube approximately as sensitive as an otherwise similar tube of standard sensitivity having an essentially clear envelope and filled with gas at less than 0.1 mms.

Title: Production of glyoxal
Inventor: PLATZ ROLF
IPC: C07C45/34
Filed: 1963-07-05
Abstract: Glyoxal is produced by reacting ethylene with nitric acid in aqueous medium in the presence of a palladium salt as catalyst at 0 DEG  to 100 DEG  C., the concentration of nitric acid in the reaction mixture being 1 to 40% by weight and the amount of palladium salt being more than 0.0001% by weight.  The ethylene feed may be pure or commercial ethylene or may contain other gases, e.g. ethane, and the nitric acid may be wholly or partly replaced by nitrogen oxides which yield nitric acid under the reaction conditions. Preferred palladium salts are the palladous salts, especially the chloride or nitrate, or complexes thereof but other palladium salts or substances which give palladium salts under the reaction conditions, e.g. palladium metal, may be employed.  The process may be performed with co- or counter-current gas and catalyst solution flow at sub-, super- or atmospheric pressures.  The catalyst may be removed from the aqueous reaction product by, for example, ion or redox exchangers or electrolytic deposition and reused.  Glyoxal is recovered from the aqueous product by conventional methods.
