Title: Lever-operated shears
IPC: B23D17/08
Filed: 1976-05-13
Abstract: 1535298 Shearing LAMINOIRS TREFILERIES CABLERIES DE LENS 13 May 1976 [14 May 1975] 19816/76 Heading B3W A shear comprises a fixed jaw, an actuating lever pivoted to the shear frame and to a pivotable jaw, first and second structures pivoted respectively to the frame and to the lever about axes parallel to the lever pivot axis on the frame, the second structure comprising an elongate member and the first having a member slidable on the elongate member in a direction normal to the pivot axis of the second structure and two elastically yieldable means, a first mounted between the frame and the first structure and exerting a force about the pivot axis of the first structure and the second mounted on the second structure between a fixed point thereof and the slidable member and exerting a force in a rectilinear direction, the two elastically yieldable means acting in directions such as to move the lever toward its position of rest. As shown, movable blade holder 4 pivoted to the shear frame 1 at 5 is actuated by a lever 9 pivoted to the frame at 10 and to a link 7, pivoted to the blade holder, at 8. The lever 9 is lowered for shearing against the action of springs 11a and 13. Torsion spring 11a urges the leaf 17 of a hinge 11 fixed to the frame counterclockwise, as viewed in Fig. 1. The coil spring 13 is mounted on a rod 12 passing through a sleeve 14 slidable vertically in a slot 19 in the hinge leaf 17. The spring 13 abuts a nut 24 at one end of the rod and a flange 23 of the sleeve 14 at the other, the other end of the rod being pivoted to the lever at 21. During shearing, the sleeve 14 moves almost continuously away from the pivot 21, shortening  the spring 13 and thus progressively increasing its force.

Inventor: BILLIN JAMES JOHN
IPC: H04N5/52
Filed: 1957-06-25
Abstract: 890,743. Automatic gain control. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 10, 1958 [June 25, 1957], No. 19933/57. Addition to 774,113. Class 40(5). In a television receiver in which, as in the parent Specification an A.G.C. voltage is derived by adding inverted synch. pulses to the complete video signal and measuring the minimum amplitude of the resultant signals, the voltages to be added are applied to separate electrodes of the rectifier from which the A.G.C. voltage is obtained. This prevents the synch. pulses being fed back into the circuit from which the complete video signal is derived. The complete video signal is fed to the grid of a triode 13 via resistor 14, whereas the inverted synch. pulses from the anode of synch. separator 5 are fed to the anode via condenser 11; the circuit is otherwise as described in the parent Specification. The complete video signal may alternatively be applied to the anode, and the inverted synch. pulses to the grid of the valve 13 (Fig. 2, not shown).

Title: Method and apparatus for geochemical surveying
IPC: G01N1/00
Filed: 1972-05-02
Abstract: 1395523 Prospecting BARRINGER RESEARCH LTD 2 May 1972 [7 May 1971] 20333/72 Heading E1F [Also in Division G1] Geological mapping is facilitated by chemical analysis of the organic constituent of airborne particles which are characteristic of geological formations in the earth. Atmospheric particles are continuously collected from known geographic locations and concentrated in a cyclone 12 or electrostatic precipitator mounted in an aircraft. The concentrated particles are then transferred into a stream of inert gas from a cylinder (Figure 1) and carried thereby through a tube 16 heated by an element 17 to a temperature between 100‹C and 700‹C. At the lower temperatures, any hydrocarbons are vapourised and may then be analysed by gas chromatography, mass spectroscopy or flame ionisation. At higher temperatures, the organic particles are pyrolised, breaking down into simpler compounds and vapours which are separated from the inorganic ash by a trap 18 or filter 24. The organic constituent is then analysed by atomic absorbtion techniques (Fig 3) or optical emission techniques (Figure 1). In Fig 3, an organic film forms on a cooled crystal 26 and infrared light passed through crystal 26 picks up absorbtion lines from the film which are detected by an infrared spectrometer 29. In Figure 1, a microwave generator 21 produces a plasma 22 in cavity 20 which produces emission lines that are analysed by a spectrometer 23. Changes in quantity of specific organic constituents merely due to changes in meteorological conditions are allowed for by normalising the measurements against either the total particulate concentration or the total organic concentration.

Title: Method of and means for manufacturing sound absorbing material
IPC: E04B1/74
Filed: 1932-07-18
Abstract: 391,342. Compound sheet materials. THOMSON, G. M., Caledonia, Ontario, Canada. July 18, 1932, No. 20343. [Class 140.] A method of making cellular sound-absorbing material consists in applying adhesive at staggered spaced positions on opposite sides of flexible material such as asbestos paper, making a stack of strips of the paper &c., allowing the adhesive to dry, expanding the resulting material to a predetermined extent, and applying an inextensible backing to one side of the expanded material. In the method described, a web of flexible material, preferably asbestos paper, is passed over two rollers in succession which apply adhesive to each side of the paper in longitudinal stripes, the stripes on one surface lying between the stripes on the other surface. The applying roll 6, Fig. 8, may be supplied with adhesive by a roll 6a and the excess adhesive removed by a notched scraper 6c. The paper is then passed between a pair of crimping rolls 9, Fig. 3, which are suitably grooved to avoid contact with the stripes of adhesive. The crimped paper A is then folded up by fingers 21 actuated by cams 23, and the folded material is received between two slowly moving belts 25 and held until the adhesive is dry. The bends which connect the flat portions of the folded material B are then removed by grinding or otherwise, so that the material then consists of separate strips connected by the lines of adhesive. This material is then expanded as shown in Fig. 7, preferably by bending it round a cylinder 27, Fig. 5, with the strips parallel to the axis. The outer face of the material is thus expanded, and a backing 28 of flexible inextensible material such as paper is applied by means of adhesive. The material is then removed and flattened. Specification 390,039, [Group XIII], is referred to.

Title: Manufacture of metalliferous azo-dyestuffs
IPC: C09B45/14
Filed: 1952-08-14
Abstract: The invention comprises chromiferous and cobaltiferous azo dyes containing monoazo dyestuffs bound in complex union, the ratio of metal atoms to dyestuff molecules being less than 1 : 1( and preferably about 1 : 2); the monoazo dyestuffs are free from sulphonic acid and carboxylic acid groups and at least one is of the formula <FORM:0724157/IV (c)/1> where X is a sulphonamide group, Y is hydrogen or a substituent incapable of salt formation and Z is hydrogen or chlorine; the other dyestuff is of the formula <FORM:0724157/IV (c)/2> or <FORM:0724157/IV (c)/3> where R is an o-hydroxy-benzene residue, and may be identical with the first. Preferred dyestuffs are those in which Y is hydrogen or chlorine and X is -SO2-NH-Cn-1H2n-1, where n is 1-7, the group X being para to the azo linkage.  The metalliferous dyestuffs may be made (1) by metallizing the monoazo dyestuffs or mixtures thereof with 1/2 to 1 atom of metal per dyestuff molecule and/or carrying out the process in weakly acid or alkaline medium; or (2) in the case of chromium by making a 1 : 1 metal complex of one of the dyestuffs by normal methods and treating it with a further mol. of the same or a different metal-free dyestuff.  Suitable metallizing agents for method (1) are cobalt acetate, cobalt sulphate, cobalt hydroxide and complex chromium compounds of dicarboxylic and oxycarboxylic acids such as lactic, glycollic, citric, tartaric, oxalic, salicylic or cresotinic.  There may be present bases, salts of organic acids or organic solvents.  For method (2) there can be used chromic salts such as the fluoride or sulphate.  The metal-free dyestuffs of the first formula above can be made by coupling a diazotized 2-aminophenol-5- or -6-sulphonamide with 5-chloro-1-naphthol or 5 : 8-dichloro-1-naphthol.  Those of the second and third formul  above are made by coupling a diazotized o-aminophenol free from sulphonic acid and carboxylic acid groups with 5-chloro-1-naphthol, 5 : 8-dichloro-1-naphthol or a 1-acylamino-7-naphthol.  The dyestuffs need not be separated from the coupling mixture before metallization. The products of the invention can be used for dyeing and printing silk, leather, wool, superpolyamides and superpolyurethanes from weakly acid, neutral or weakly alkaline baths, which may contain assistants such as polyglycol ethers.  Examples show the preparation and metallization of the following dyestuffs: (1) 2-aminophenol-5-sulphonamide --> 5 : 8-dichloro-1-naphthol, cobalt and chromium; (2) 4 - methoxy - 2 - aminophenol - 5 - sulphonamide --> 5 : 8 - dichloro - 1 - naphthol, chromium; (3) dyestuff of (1) together with 4-chloro-2-aminophenol --> 5 : 8-dichloro-1-naphthol, chromium.  Tables are given of other dyestuffs that can be metallized, and other suitable components therefor are mentioned.  A further example shows the dyeing of wool and nylon with the cobalt derivative of (1) from a neutral or acetic acid bath.  Specifications 498,575 and 637,404 are referred to.
