Title: Revulotion-counting mechanisms
IPC: G06M1/24
Filed: 1972-01-13
Abstract: 1338164 Counting apparatus FERRANTI Ltd 13 Jan 1972 [27 Jan 1971] 3244/71 Heading G4D In a drum type register of the kind having a transfer wheel 18 between the first and second digit wheels 10, 27 and driven by an energy storing weight 29 from the first digit wheel 10, the transfer wheel 18 is provided with a flange 19 carrying some numerals which overlie a modified series of numerals 12 of the first digit wheel 10 so arranged that at the transfer point the visible first digit changed rapidly. As shown wheel 10 has numerals ... 8, 0, 0, 1 while the flange has 9, 9, 0; as the two wheels 10, 18 rotate together the first 9 appears in the viewing window covering the first 0; on further rotation the second 9 appears covering the second 0 and then the weight 29 falls turning the transfer wheel 18 (and the second digit wheel 27 through transfer mechanism 26), quickly, clear of the first digit wheel to bring its second 0 into view. Should the transfer take place too soon, e.g. due to a shock, or too late, e.g. due to excessive friction then the first zero on wheel 10 or the zero on wheel 11 will appear, the maximum error in reading being one unit. This can be detected by an additional scale 13 inscribed on a flange 13 of the first digit wheel: if these small figures disagree with the units reading the reading must be corrected by adding or subtracting one unit.

Abstract: 451,502. Centrifugal dust-collectors. NORTONS (TIVIDALE), Ltd., Hecla Works, Tipton, Staffordshire, and McKEOWN, C. G., 2, Roden Terrace, Woodstock Road, Belfast. Feb. 1, 1935, No. 3398. [Class 23] In a dust-collector of the cyclone type, the dust-laden air enters by a tangential inlet 2 and travels along a path of diminishing cross - section to increase its forward speed. This is secured by placing the clean gas outlet 3 eccentrically in the cylindrical casing 1. The truncated cone part 4 has its upper edge coincident with the cylindrical part 1, but its lower edge is concentric with the outlet 3. The inclination of the wall therefore varies and becomes steeper from the point first encountered by the air. A second cylindrical part 5 is arranged below the part 4 and has a diameter larger than that of the outlet 3. A conical part 6 which may have a discharge valve, receives the separated dust. The outlet tube 3 leads to a volute chamber 7 with a discharge pipe 8. The separator may be used under pressure or suction.

Jan. 31, 1930, No. 3419. [Classes 70 and 87 (ii).] Sheet material is formed from heat coagulable aqueous dispersions of organic substances such as rubber &c., by forcing the dispersion through a nozzle or space formed between plate-like elements heated to the coagulation temperature of the dispersion. Threads, cords or woven fabric which, before entering the dispersion, may be passed through a washing bath of cold, warm or slightly alkaline water to guard against premature coagulation, may be led between the plates simultaneously with the dispersion so as to form rubberized fabric, and a liquid such as water may be introduced between the plates to promote even extrusion. The part of the nozzle adjacent to the bulk of the dispersion may be cooled to prevent premature thickening of the latex. As shown, Fig. 3, fabric &c. 15 passes through a preliminary washing bath 19, through a vessel 1 containing the dispersion and is then drawn through the nozzle 4 by rollers 17 and drum 18. Adjustment of guide roller 21 and rollers 17 varies the thickness of the rubber on each side of the material. The nozzle, Fig. 4, comprises plates 2 and 3 spaced apart by members 5, and is provided with a cooling chamber 23 fitted with baffle-plates 25 through which a cooling fluid is circulated, and with a heating chamber 24 containing an electric resistor 6.

Abstract: 1375124 Recovering cellulose E I DU PONT DE NEMOURS & CO 24 Jan 1973 [25 Jan 1972] 3528/73 Heading CBA Regenerated cellulose is recovered from a comminuted material containing regenerated cellulose, a softener and a coating by a process having the following steps: (i) removing the softener with an extraction agent, whilst the internal pore-structure of the cellulose is kept open, (ii) removing the coating by means of a solvent, (iii) forming a slurry of the solventladen material with water and additional coating solvent, (iv) drying the slurry to remove coating solvent and water to yield dried regenerated cellulose. The process is particularly concerned with removal of softener and a polyvinyl chloride coating from "Cellophane" (Registered Trade Mark), films. Here the comminuted film is swollen with water and the softener extracted by counter-current extraction with ethanol. The material is then dried and the coating removed by counter-current extraction with tetrahydrofuran (THF). The final product is obtained by drying with a stream of gas (e.g. N 2  at 75‹ F.), which removes the THF first.

[Also in Division C3] Preparations are described of oxalamidehydrazide compounds of the formula where R 1  and R 2  each represents alkyl (e.g. methyl) and R represents a radical of the formula or where R 4  is H or methyl and X is a -(CH 2 )n- or phenylene group, n being an integer from 1 to 4. In one process (R being CH 2  = CR 4 - COO-C 6 H 4 -), diethyl oxalate is reacted with an aminophenol to form the amide-ester which is then reacted with N,N-dimethylhydrazine and the phenolic group is esterified with (meth)- acrylic acid chloride. In another process (R being CH 2  = CR 4 -COO-(CH 2 ) n -), an aminoalcohol is esterified with (meth)acrylic acid chloride and the product is reacted with oxalic acid ethyl ester-N,N-dimethylhydrazide. In a third process (R being CH 2  = CR 4 -CONHC 6 H 4 -), nitrophenyl-oxalamide ethyl ester is catalytically reduced to the corresponding aminophenyl compound, which is reacted with N,N-dimethylhydrazine and then (meth)acrylic acid chloride. The oxalamide-hydrazides can be quaternized at the nitrogen atom of the -NR 1 R 2  group, e.g. with dimethyl sulphate or methyl toluene sulphonate. The products (quaternized or non-quaternized) are used as comonomers for dyeable acrylonitrile co-polymers (see Division C3).

Title: Transistor crystals
IPC: H01L29/00
Filed: 1957-02-05
Abstract: A method of growing a PNP germanium or NPN silicon body for transistors (see Group XXXVI) comprises the steps of preparing a melt of the semiconductor containing an excess of donor (or acceptor) impurity, growing part of the melt on to a seed crystal by the pulling technique, adding donor and acceptor impurities simultaneously to the remaining melt, and continuing growth on to the seed.  The relative amounts, segregation coefficients, and diffusion constants of the added impurities are so chosen that the material crystallized from the melt is of the same conductivity type throughout but so that during the second stage of growth the acceptor (donor) impurity diffuses into the material grown in the first stage to produce a region of opposite conductivity type at the interface. In one example a seed crystal is drawn at 940 DEG C. from a melt of germanium doped with gallium.  When half the melt has grown into a P type crystal withdrawal is stopped and a germanium-arsenic-gallium alloy added to the melt.  The temperature is raised to 980 DEG C. for 10 seconds to dissolve the alloy, and the crystal allowed to melt back partially to remove material into which uncontrolled diffusion may have taken place. The remainder of the melt is then pulled at 940 DEG C.  In another example a seed is drawn at 1420 DEG C. from antimony doped silicon. When half the melt has been pulled arsenicaluminium alloy is added and after a period in which the temperature is raised to 1440 DEG C. to dissolve the alloy and partially melt back the crystal, pulling is resumed at 1390 DEG C. Reference has been directed by the Comptroller to Specification 779,660.ALSO:An alloy used in the preparation of junction transistors (see Group XXXVI) is made by fusing together 50 grams of germanium, 400 milligrams of arsenic and 600 milligrams of gallium, pulverizing the resulting product and then re-fusing it to form a pellet.  A silicon-antimony alloy containing 2% by weight of antimony is also used.  Reference has been directed by the Comptroller to Specification 779,660.

The movement of the lower plate backwards and sideways by means of the tag d causes the men to form fours. Additional slides m, n under the plates a, b engage the lower ends of the pins so that their longitudinal movement gives a rotation to the men. The men may be detachably attached to their pins which may have square or flattened ends. Where more extended turning movements are required the pins may be actuated by racks. In a simpler construction, the turning movements are dispensed with and the upper plate is formed with wide slots in place of the independent slots c. In this arrangement the men may be represented by ink marks, beans or the like, and the position of the section leaders may be shown through holes in the upper plate. The formation of blank file can also be illustrated by the apparatus. The Provisional Specification states also that the men may have pivoted arms so that by tilting the board they swing into positions representing " present arms and " shoulder arms."
