Title: Improved process for producing artificial silk from viscose
IPC: D01F2/08
Filed: 1930-07-03
Abstract: To permit the operations of washing &c. and drying to be carried out on the material in an unstretched state while still obtaining a soft lustrous viscose silk, there is used a coagulation bath containing not less than 200 grams, preferably not less than 230 grams, of sodium sulphate per litre, a proportion of sulphuric acid which in relation to the sodium sulphate is insufficient to convert all of the latter into bisulphate, and zinc sulphate in a proportion not less than 5 grams per litre.  The proportion of zinc sulphate is preferably adjusted according to that of the sulphuric acid; thus, with 100 grams per litre of sulphuric acid there is used 10 grams per litre of zinc sulphate, with 110 grams sulphuric acid 15 grams zinc sulphate, and with 135 grams sulphuric acid 25 grams zinc sulphate. In an example, the coagulation bath is made up of 110 grams sulphuric acid, 250 grams sodium sulphate and 15 grams zinc sulphate per litre. The silk may be spun according to the centrifuge method, and the cakes may be either rewound in the moist acid state into hanks and washed and dried while hanging freely, the after-treatment if desired following directly the first washing, or they may be washed, after treated and dried without rewinding, in which case stiffening bodies for supporting and stretching the cakes are not employed.

Title: Improvements in changing the feed-laps in textile machines
IPC: D01G19/14
Filed: 1947-07-28
Abstract: 643,477. Feeding laps in textile combing &c. machines. HINSON, O. C. July 28, 1947, No. 20315. Convention date, May 17, 1945. [Classes 120 (i) and 120(ii)] In a textile machine, such as a Heilmann comber, wherein fibres are fed in lap form from a lap roll mounted on spaced rotatable supports, means are provided for automatically replacing an almostexhausted lap roll when the latter descends between the supports, by reason of its reduction in diameter. The lap from the almostexhausted roll may be severed and the fresh lap superimposed on the end of the severed lap. A fresh roll 23 may be held vertically above a working roll 15 by rollers on shafts 25, each fixed in the upper ends of a pair of arms 27 swinging on pivots 29, each front arm 27 having a rearwardly extending integral toe 33, which overlaps a corresponding integral toe 35 on its associated rear arm 27. To maintain the fresh roll 23 in its reserve position until needed, a detent latch 39 is slidably mounted in a position normally preventing the forward swinging movement of front shaft 25. When latch 39 is retracted, the front shaft 25 swings forward and the toe 33 releases its pressure on toe 35, permitting rear shaft 25 to swing backwards, thus releasing the fresh roll 23 to fall, under the control of side pressing members, such as 67. The latch 39 is connected by a link 47 to the end of an arm 49 fixed on a rockshaft 51. A pair of cradles 55 is fixed upon the rockshaft 51 to catch and hold the spent lap roll 15 when, by reason of its reduced diameter, it falls between support rollers 13. A cross-member 57 supported by the cradles 55 acts as a trip, when the spent lap roll 15 sags between rollers 13 to make contact with it, thus tilting cradles 55 and operating latch 39. The cross-member 57 is provided with a row of comb teeth 59 which pierce the lap from the spent roll 15 as it rests on the cradles 55 and, by reason of the continued feeding of the lap over the front supporting roller 13, causes the lap to be severed. The lap from the fresh roll 23 is superposed on the end of the lap of the spent roll 15 and together they pass over front supporting roller 13, beneath an apron 95, Fig. 3, and between the apron and a metal guide duct 101 to a feed roller 9.

Title: Improvements in or relating to fuel systems of gas turbine engines
Inventor: JUBB ALBERT
IPC: F02C9/16
Filed: 1955-07-15
Abstract: 810,804. Gas turbine plant. ROLLS-ROYCE Ltd. July 13, 1956 [July 15, 1955], No. 20623/55. Class 110 (3). [Also in Group XXIX] The governed maximum speed of a gas-turbine engine is increased when the sensed airintake temperature is above a pre-selected value. The fuel for a gas-turbine passes from a tank 50 and booster pump 51 through a variable capacity swashplate pump 53 and fuel control device 73 to the combustion equipment 20c of the turbine. The pump 53 acts as an enginespeed governor by virtue of centrifugal pressure, generated in passages 68 in the pump rotor, transmitted to one side of a diaphragm 13 balanced against pump inlet pressure; the diaphragm controlling a valve 11 modifying pressure on a piston 60 controlling the angle of the swashplate in known manner. The diaphragm 13 is also controlled by a spring 16 connected to a differential area piston 17, the smaller area of which is subjected to pump delivery pressure through a duct 31. Delivery pressure is also fed to a chamber 29, open to the larger area of the piston 17, through restrictions 27 and 30, a bleed valve 25 being situated between the restrictions. The valve 25 is controlled by a spring 24 and a Bourdon tube 21a sensitive to air temperature at the compressor intake 20a of the engine. In operation at low altitude the engine speed is governed by a pre-selected maximum by the pressure difference on the diaphragm 13 together with the force exerted by the spring 16; the valve 25 being open under the influence of the Bourdon tube 21a and causing a lower pressure to exist in the chamber 29, such that the piston 17 is against a stop 32. As altitude increases and the intake temperature drops, the Bourdon tube contracts to close the valve 25 and equate the pressures on the two sides of the piston 17. The piston 17 moves to the left and relieves the diaphragm 13 of the load of the spring 16, thus lowering the maximum governed engine speed. The values of the engine speeds and intake temperatures are such that the value of N/T, where N is the engine speed and T the intake temperature, at which the engine tends to surge is not exceeded.

Abstract: 1298866 Semi-conductor devices; image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 May 1970 [6 May 1969] 21111/70 Headings H1D and H1K A target plate for a television camera tube comprises a semi-conductor plate having a mosaic of regions forming junctions with a substrate of the opposite conductivity type, the regions being separated by grooves containing insulating material which covers the surface of the substrate and the edges of the junctions but does not completely fill the grooves. A first embodiment, Fig. 2, is produced by depositing B 2 O 3  on one face of an N-type Si substrate 10, heating to diffuse-in B, and etching to remove the surface oxides. The surface is then masked with a layer of Si 3 N 4  in which windows are formed by utilizing a SiO 2  and photoresist masking and selective etching technique. Grooves 12 are then etched in the Si surface to divide the diffused layer into a mosaic of separate circular regions 11. The wafer is then heated in N 2  saturated with water vapour to form oxide layers 15 on the surfaces of the grooves and the remaining Si 3 N 4  masking layer is removed by selective etching. In a modification, Fig. 9 (not shown), SiO 2  is utilized instead of Si 3 N 4  as the etching mask, and after oxidizing the surface of the grooves the wafer is coated with photoresist which forms a thinner layer on the mesas than in the grooves. After a brief exposure the thin part of the photoresist can be removed to enable the masking layer on top of the mesas to be etched away leaving the oxide layers in the grooves untouched. In another modification, Fig. 10 (not shown), Rh is used as the etching mask, this being provided electrolytically after diffusing-in B. This metal layer is not removed after the oxidizing step since it overhangs the grooves and helps prevent the electron beam from charging the surface of the oxide layer in operation. The surface walls of the grooves may be highly doped the same conductivity type as the substrate by diffusion after forming the grooves but before oxidation, Fig. 11 (not shown). The oxidation of the walls of the grooves may occur during this diffusion step. In another variation the grooves may be formed and oxidized and the etching mask removed before diffusing-in impurities to form the active regions 11. An impurity may be diffused into the lower face of the wafer to reduce surface recombination, Fig. 12 (not shown), and during the diffusion a doped oxide layer may be formed which aids this effect. Alternatively the lower face may be merely oxidized, Fig. 13 (not shown), and this may be performed simultaneously with the oxidation of the grooves. The mosaic elements may have a transistor structure Figs. 14 and 15 (not shown). The semi-conductor material may be Si, Ge or a III-V compound, and may be formed as a layer on an insulating transparent substrate. The insulating layer in the grooves may be coated with phosphate glass or a resistive layer, e.g. of PbO, Sb 2 S 3  or GaAs to allow charge built up on the oxide by the scanning beam to leak away.
