Patent GB-998539-A (GB)
Title: Chemotherapeutic agent and process for preparing same
IPC: C12P1/04
Filed: 1962-05-02
Abstract: The antibiotic material referred to as "Iytic factor" is produced by cultivating a lytic factor-producing strain of the micro-organism Staphylo coccus stapholyticus especially S. stapholyticus-NRRL B-2628, on an aqueous nutrient medium containing assimilable sources of carbohydrate and organic nitrogen.  Cultivation may be carried out at 30-40 DEG  C., pH 7.3-7.7, under submerged aerobic conditions. The antibiotic material is recovered by precipitating the filtered broth with a water-soluble hydrophilic reagent, e.g. ammonium sulphate, bromide, carbonate, dithionate or formate or sodium sulphate.  The antibiotic material is purified by partition chromatography absorption on a diethylamino cellulose column and elution with sodium chloride, dialysis, electrophoresis, paper chromatography, or solvent extraction.  The antibiotic may also be recovered by dialysing a filtered broth thereof against "Cellophane" (Registered Trade Mark) containing a hydrophilic substance, e.g. dextran or polyethylene glycol.  Lytic factor is a proteinaceous anti-bacterial agent which has the capacity to lyse viable cells, heat killed cells and cell walls of bacteria of the genus staphylococcus other than S. stapholyticus; it has an isoelectric point at pH 11;it is labile and non-dialyzable; is hydrolysed with loss of lytic activity by trypsin; it yields ammonia, aspartic acid, threonine, serine, proline, glutamic acid, glycine, alanine, valine, cystine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine and arginine on acid hydrolysis; it has a U.V. maximum at 278 mm ; molecular weight 2 x 104-3 x 104 and exhibits I.R. absorption maxima at 2.8, 3.1, 3.4, 3.5, 5.1, 6.1, 6.4, 6.8, 7.0, 7.1, 7.3, 7.4, 8.2, 8.4 and 8.9 m .  The antibiotic is used in injections, ointments, solutions, suspensions, salves, suppositories, vaginal tablets or lozenges to treat staphylococcal infections.

Title: An improved polishing machine particularly for table cutlery
IPC: B24B19/00
Filed: 1930-06-02
Abstract: 349,783. Polishing-machines. ERN, R., 70, Kornerstrasse, Solingen, Germany. June 2, 1930, No. 16951. [Class 60.] In a polishing- machine, particularly for table cutlery, of the kind comprising a carrier having holders for conveying ' the articles up to and past a rotary polishing disc, the holders are yieldingly mounted so that while the articles are pressed against the disc they adjust themselves angularly in two or more planes relatively thereto. The carrier consists of a slowly rotating disc 3, carrying pivots 4 on which are mounted levers 5 provided with holders 16 for the articles to be polished, such as spoons 8. The levers are normally kept in contact with stops 12 by means of springs 10 but rock about their pivots 4 when the articles are pressed against a rapidly rotating polishing disc 14 so as to adapt themselves to the polisher according to their shape. The holders are rockable about pivots 15 on the levers 4, resilient means normally maintaining the holders perpendicular to the plane of the disc. On encountering the polishing disc 14 the holders are rotated gradually about the pivots 15 into the plane of the disc, simultaneously with movement of the levers 5 about their pivots 4, thus producing a combination of longitudinal and lateral polishing on the articles. The discs 3 and 14 are both rotated in the same direction.

Filed: 1942-12-03
Abstract: 562,185. Compound fabrics. GLENDINNING, E., and BINNS, F. Dec. 3, 1942, No. 17218. [Class 140] [Also in Group IX] A relatively thick fabric comprises a woven cloth A formed into a succession of transverse folds intersected longitudinally by warps of a ground cloth B lying substantially in one plane. A length of the cloth A is woven and is folded into loop form. by being beaten up and a comparatively short length of the ground cloth is woven ; the warps of the cloth A have been passed through the warps of the ground cloth and a length of fabric A is woven on the opposite side of the ground cloth. The amplitude of the folds on opposite sides of the ground cloth may be symmetrical or otherwise and areas of loops of large amplitude may be spaced by areas of smaller amplitude. More than one ground cloth B may intersect the folds of the cloth A, or, alternatively, one or more additional sets of ground warps t, u may be provided. Fillings or independent warps may be provided between the loops of the folded fabric. Padding material may be formed by superposing a number of pieces of the fabric and securing them by adhesive or stitching. The folds in adjacent layers may be arranged at right angles to one another, and either the warps or wefts of the fabric, or both, may be of asbestos. Alternatively, the warps or wefts, or both, may be of fine wire. The layers of fabric may be separated by cloth, felt, rubber, rubberised fabric, paper, wire net or wire cloth. The fabric may be made upon a Dobcross loom in which means are provided for interrupting the take-up, and for relieving the tension in the warps for the folded cloth so as to facilitate the folding operation. The lever 14 carrying the pawl 13a for rotating the cloth roller is held away from its driving connection g<2> with the sley, as desired, by a cord 15a under control of the usual dobby jacks 16. A second dobby jack 17 serves to lift the counterweighted lever 17d which normally holds the back roller for the warps of the folded cloth against the warps, and so relieves the tension in those warps during beating-up so that the folding of the cloth is facilitated.

Class 145  Blocks 6 of timber are split into lathes by passing. them between a series of opposed rotary knives 32, 33 of which the top or bottom or both series are of progressively increasing diameter so that the depth of cut increases until the laths are completely severed. The knives are clamped between spacers and sleeves 30, 31 carried by shafts 28 and the sleeves are rotatably carried in bearings 25: the knives are either freely rotatable or, as in Fig. 9, are rotated by a motor through a single chain passing over sprockets 85, the sprockets being of approximately the same diameter as the corresponding knives so as to give them a constant linear cutting speed.

Title: Improvements in or relating to brake actuators
IPC: B60T17/08
Filed: 1961-05-16
Abstract: 911,590. Fluid-pressure brakes. CRANE CO. May 16, 1961 [May 16, 1960], No. 17763/61. Class 103 (1). A diaphragm type air-pressure operated brake actuator has an auxiliary actuator whose piston-rod acts on the diaphragm under spring- pressure when air-pressure on one side of the piston fails. The brakes are normally applied through an actuator rod 16 on admission of air pressure to the space 20 behind a diaphragm 12. Line air pressure admitted to the interior of a cylinder 21 integral with the rear wall 10 of the actuator cylinder forces a piston 22 to compress springs 45, 46, 47 and 48, the latter being fully compressed against an end cover 50. On line pressure failure the springs move the piston 22 forwards and a hollow piston-rod 31 moves the diaphragm 12, through a selfaligning pad 39, to apply the brakes. The cover 50 is retained in the end of the cylinder 21 by bayonet catch means 51, 59 and a headed rod 53 secured to the cover 50 and slidable within the piston-rod 31 prevents separation of the piston 22 and cover 50 under spring pressure when the cover is removed.

Abstract: 1508732 Feeding webs GENERAL TIRE & RUBBER CO 30 April 1976 [15 Aug 1975] 17815/76 Heading B8R [Also in Divisions B5 and B7] An extruded elastomeric tyre tread is thickened at its mid length portion prior to application to a carcass, the thickened portion counterbalancing the thickening produced by the overlapping ends of the tread. The apparatus for producing the thickened portion comprises a pair of driven rollers 21, 22 over which the tread is passed and a vertically movable assembly 12 above the tread. Equidiameter rollers 31, 32 of the assembly 12 coact with rollers 21, 22 (Fig. 9) to advance the tread, and rollers 22, 32 drive the tread faster than rollers 21, 31 so that a thickening 13 is produced. The different drive rates result from different diameters of rollers 21, 22 and/or their sprockets. In the event, that rollers 31, 32 are coupled by a chain, the sprockets associated with those rollers are of different diameters. Preferably the surface speeds of rollers 21, 22 are in the ratio 1 to 1À25, and the surface speeds of the rollers 31, 32 are in the ratio 1 to 1À33. Idler rollers 23, 33 prevent buckling of the tread.
