Abstract: 1 - Ethyl - 2 - methyl - 5 - carboxy - benzimidazole is prepared by heating 3-nitro-4-chlorobenzoic acid with ethylamine to give 3-nitro-4-ethylamino-benzoic acid, reducing the nitro-group and refluxing the product with acetic acid and hydrochloric acid to effect ring closure. The product is quaternized by heating with ethyl toluene sulphonate. 1-Ethyl-2-methyl-7-carboxy-benzimidazol is similarly prepared from 2 - bromo - 3 - nitro - benzoic acid, and quaternized by heating with methyl iodide.  1 - Ethyl - 2 - methyl - 7 - carbethoxy - benzimidazole, prepared as described in Example 13 of Specification 955,961, is quaternized by heating with ethyl iodide, ethylene bromohydrine or N-acetyl-4-bromobutane sulphonamide. Specifications 904,332 and 955,962 also are referred to.ALSO:Cyanine and merocyanine dyes are described which contain a benzimidazole nucleus having a 5- or 7-carboxyl or a 7-carbethoxy substituent. Examples are given of the preparation of carbocyanine dyes by condensing the appropriately substituted 2-methyl-benzimidazolium salt with ethyl ortho formate to give a symmetrical dye, or with heterocyclic bases (such as benzthiazoline or benzoxazoline) having a reactive b -phenylimino-ethylidene group or with cyclammonium salts such as 2-(b -acetanilidovinyl) - 3 - ethyl - thiazolinium bromide and 1:3 - diethyl - 2 - {b  - (p - tolusulpho - anilido)-vinyl} - 5:6 - dichlorobenzimidazolium chloride to give unsymmetrical dyes.

Title: Improvements in and relating to filament support wire forming apparatus
IPC: H01K3/10
Filed: 1949-07-22
Abstract: 658,368. Supports for electric lamp filaments. BRITISH THOMSON-HOUSTON CO., Ltd. July 22, 1949, No. 19355. Convention date, July 23, 1948. [Class 39(ii)] In apparatus for bending the filamentsupporting wires of lamps having a long helical filament mounted on closely arranged supports, as in train headlights or spotlights, a stem 1, Fig. 4, with exhausting tube 12, and wires 2, 3 radiating from a button 6 at the end of an arbor 7 is located horizontally with the button positioned in a die-block 9, Fig. 1, and a manually-operable knob 5 at the front of the apparatus is pushed inwardly to move a wire-bending or forming head 8 from an axially offset position near the front of the apparatus to a position in axial alignment with the stem 1, the movement being continued axially towards the die-block to bend the wires around the end and over the surface of the die-block. The front edge of the die-block is notched radially to receive the wires 2, 3 which, when the stem is inserted in the apparatus, are arranged as shown in Fig. 4. Movement of the forming-head 8 is effected by providing it with a,lower extension 18 which grips the operating rod 17 carrying the knob 5, the lateral component of the movement being derived from a pair of oblique cam faces 19, 19', Fig. 2, providing a guide channel through which the extension 18 passes. The wires 2 are the first to be bent, by pivoted fingers 20 located in radial planes which intersect at a common point on the axis of the forming-head 8, the number of fingers corresponding with the number of wires 2, there being three in the example. As the head 8 advances, the fingers 20 engage and wipe the outwardly' extending portions of the wires over the rim and outer face of the stationary dieblock 9. The wire-engaging edges of the fingers 20 have each a groove to receive a wire, which is given a right-angled bend, and with continuing advance of the head 8 the bends are maintained by hold-down fingers 28 which are clamped in the head radially inwardly of the respective fingers 20. The parts of the wires 2 held horizontal by the fingers 28 are disposed along the outside faces of a movable die-block 27 and given a further right-angled bend near their ends by bending them around the rear of the die-block. This latter bend is also effected by the fingers 20, each of which has an outwardly projecting pin 31 positioned to engage the face of a fixed cam 32. The bending of the shorter support wires 3 is effected midway in the movement of the bending-head 8 and just prior to the final bending of the wires 2, the wires being engaged by a pair of fixed bending fingers 46 which lie within grooves in the head 8, between the fingers 20. The wires 3 are thus bent at right-angles over the outer face of the die-block 9. Specification 390,807, is referred to.

[Also in Division F4] A metal grid for distributing a gas into a bed of fine solid particles, e.g. in carrying out a chemical reaction between the gas and a fluidized bed solid particles, comprises an assembly of two types of bar of rectangular cross-section supported on horizontal rods 3, so that the bars are in contact with each other laterally. One type of bar 1 has horizontal gas passages 5 through it, whereas the other type of bar 2 is provided with notches 6. The gas, supplied to the under surface of the grid, passes into the downwardly-facing troughs formed by the notches in the bars 2, flows through the passages in bars 1, and passes out into the mass of solid particles above the grid via the upwardly-facing troughs formed by the notches in the bars 2. The ratio between the length and diameter of passages 5 is modified by a juxtaposition of a variable number of bars 1. The diameter of the passages should be greater than five times the diameter of the largest particles capable of being entrained by the gas passing through the grid.

Abstract: 594,134. Jointing. HOWLETT, J. W., and WELLWORTHY PISTON RINGS, Ltd. Oct. 12, 1944, No. 19647. [Class 83 (iv)] Soldering.-A method of securing a metallic member in another metallic member of a machine when there is to be a transfer of heat between the members, comprises shaping the members to have an interference fit with one another, coating the engaging surface of at least one of the members with a mixture of a non-corrosive volatile carrier liquid and a powdered metal or alloy or mixture thereof and then inserting the one member into the other member. Before the parts are brought together, the inserted member may be frozen or the receiving member may be heated. In the case of a valve seat insert, it is preferred that the external surface of the insert should be fine-finished and the wall of the recess rough finished, the latter surface only being coated. The metallic powder is preferably of a relatively soft, good, heat-conducting material such as aluminium, copper, gold, silver, zinc, bismuth, tin or cadmium or a mixture thereof and the carrier liquid, alcohol, ether, acetone or petrol. When aluminium, zinc, bismuth, tin or cadmium powder is used, it may be sintered or welded to the surfaces of the two members by the application of heat or even by the heat generated in the fitting process.
