Title: Improvements in or relating to artificial fertilisers and methods of producing same
IPC: C05G5/23
Filed: 1937-11-19
Abstract: A fertilizer is obtained by heating an aqueous solution of glucose with an alkali metal carbonate (K2CO3 or Na2CO3), separating the CO3-ions from the solution as calcium carbonate after precipitation with calcium nitrate, and mixing the thus treated solution with glycerine.  The fertilizer may contain, in addition, neutral mixtures resulting from the saponification of animal or vegetable fats, oils or waxes, phosphates, additional amounts of nitrates, albumin, gelatine, casein, gum and/or mucilaginous vegetable substances, clay, materials capable of forming humus or vegetable earth such as straw, peat-dust, dry leaves, &c., and urea.  The nitrates and phosphates may be introduced by neutralizing the alkaline saponification lyes with phosphoric and/or nitric acids.  The product may be mixed with the materials capable of forming humus or vegetable earth and the glycerine-containing saponification product, the mixture being piled up and sprinkled with water at regular intervals while it is decaying.  The fertilizer may be sprayed in a liquid state or may be dried to convert it into a granular form.

Title: Dyeing of silk wastes
IPC: D06P1/12
Filed: 1961-09-06
Abstract: Natural silk wastes are dyed with azo dyes formed in situ by treating the silk material with a mineral acid prior to diazotizing the silk itself and coupling.  Specified acids are dilute sulphuric or hydrochloric acid.  The process may be accomplished by treating with the mineral acid with moderate heating up to 50 DEG C. to penetrate the greasy surface of the silk wastes, adding sodium nitrate and diazotizing the silk, coupling with a suitable compound in a neutral or weakly alkaline medium and subsequently heating with a metal salt in an acid medium. Suitable couplers are b -naphthol, resorcinol and 1-phenyl-3-methyl-pyrazolone and suitable metal salts are copper or nickel salts, chromates and bichromates.  Examples are given. Specification 845,764 is referred to.

Title: Improvements in or relating to methods of treating semi-conductive devces
IPC: H01L21/00
Filed: 1958-10-09
Abstract: 870,347. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Oct. 9, 1958 [Oct. 28, 1957], No. 32259/58. Class 37. Semi-conductor devices comprising bodies of germanium or silicon or germanium-silicon alloy are treated by being wetted with an aqueous solution of hydrogen peroxide and then baked in an atmosphere containing oxygen. When devices which comprise rectifying junctions are thus treated their reverse currents are reduced and, in the case of transistors, current amplification is increased. The necessary concentration of hydrogen peroxide is at least 10% and is preferably 30%. The temperature for the baking step is preferably between 100‹ C. and the lowest melting-point of any alloy in the device being treated. Baking may take place in air and should continue for at least 15 minutes; one hour is preferred. A short treatment with an etchant which includes hydrofluoric acid and nitric acid may advantageously precede the peroxide dip. If inorganic salts are formed on the surface of the device during the baking step, the device should be rinsed in deionized water during or after the bake; if the latter, a subsequent drying step is necessary. The Specification contains examples of the results produced by the treatment of PNP germanium transistors comprising lead-indium alloyed pellets, nickel wire electrodes attached thereto, and antimony-coated base-plates; also of an NPN germanium transistor comprising lead-arsenic pellets and a gold-coated base-plate.

Class 100(i) [Also in Group XXX] In a machine comprising an endless conveyer to which sheets from a printing or analogous machine are delivered the conveyer 1 is periodically moved forward at an accelerated rate by rollers 10, 11 adapted for periodic co-operation to engage and grip the conveyer between them and effect the accelerated advance. The conveyor is continuously driven by a roller 4 on a shaft 5 which also carries a toothed wheel 26 driving a small sprocket 28, which through wheels 30, 32 drives the roller 10. Rollers 10 and 11 are geared together by gears 23, 24, but are of different diameters so that rubber protuberances 18, 19 on the rollers come together as shown to grip the conveyer and accelerate it only once in a predetermined number of roller revolutions which may be changed by varying the ratio of the number of teeth on gears 23, 24. Sheets 9, 9<SP>1</SP> fed to the conveyer are thereby separated and counting of the sheets facilitated. Alternatively the periodic acceleration may be obtained by providing one roller with a protuberance and one plain roller which is moved into gripping location at predetermined intervals.

Title: Machine for making non-circular tubing with helically wound strip

IPC: B21C37/12
Filed: 1952-12-23
Abstract: 707,369. Making tubing. TITEFLEX, Inc. Dec. 23, 1952, No. 32674/52. Classes 83 (2) and 83 (4) Coiling; soldering; seaming.-Helically wound tube of polygonal cross-section for electronic equipment is formed on an intermittently rotated polygonal mandrel by rollers independently pivoted on a frame rotated in opposite directions about the mandrel in timed relation with the mandrel. A rectangular sectioned mandrel 14 on a shaft 13 is rotated by a chain 20 from a Geneva stop mechanism 23 through shafts 30, 37 from an electromotor 60 and clutch 56. By throwing out the clutch by a lever 58 the machine can be rotated by a handwheel 66 for setting up. The shaft 37 through chain 44, belt 49 :and slipping pulley 64 rotates bending rolls on a carriage 48 reciprocated by a rod 74. When the ,rod 74 pushes the carriage to the right, Fig. 1, the belt 49 is loosened to interrupt the feed of the strip. The shaft 30 carries a cam 35 cooperating with a follower on a lever 88 hinged on a shaft 90 and biased by springs 92. Reinforcing wire 77 and solder wire is fed from spools. A frame 81 is mounted coaxially with the mandrel and is connected by a link 84 with the 'lever 88, controlled by the cam 35, and to the rod 74. The cam 30 and the springs 92 oscillate the frame 81 and reciprocate the carriage 48. The frame 81 carries brackets 97 with levers 99 bearing rolls 101, 102, 103, 104 which bend the strip and seam the tube, Fig. 8 (not shown)..Each roll is moved radially by the outside of the mandrel and an internal cam. The roll 101 is connected to the rod 74. Operation. The mandrel rotates 90 degrees to the position Fig. 2 and the frame 81 is oscillated clockwise. The roller 101 moves along the top side of the mandrel and pushes the rod 74 to the right to maintain the pull on the strip. The roll 102 runs round the bottom comer of the mandrel and a guide 113 .on a spring-urged lever 114 maintains the mating edges of the strip vertical as the roll 102 starts the seaming. The rolls 103, 104 act similarly. The mandrel then moves another 90 degrees and simultaneous movement of the frame 81 in the same direction at a slower rate and the roll 101 travels round the corner of the mandrel to guide the strip. The rolls 102, 103, 104 move similarly. The mandrel then turns another 90 degrees in the same direction and the parts resume the position, Fig. 2.
