Patent GB-189639-A (GB)
Title: Improved manufacture of hollow textile fibres
IPC: D01D5/24
Filed: 1921-11-15
Abstract: Gas-filled fibres obtained for example by spinning a viscose or similar solution containing dissolved or admixed air, or containing a chemical which forms gaseous bubbles within the fibre when the latter issues from the spinning machine or draw-plate, are submitted to treatment so that the air or other gas is removed from the fibre, the walls of which collapse one against the other.  Thus, air may be removed by treatment with air-free water or with water under pressure.  Other means such as the progressive action of vacuum or pressure may be employed.

Title: Magnetic device of the transfluxor type
IPC: H03K17/82
Filed: 1955-10-25
Abstract: 817,252. Magnetic core storage devices. RADIO CORPORATION OF AMERICA. Oct. 25, 1955 [Nov. 1, 1954], No. 30524/55. Class 38 (2). [Also in Group XXXIX] A magnetic device for controlling, storing or switching electrical signals, comprises a magnetic core of material having a substantially rectangular hysteresis loop with three or more holes 12, 14, 16, 18 through which pass input windings 24, 26, 28, 30 disposed radially about a hole 20 through which passes the output winding 34, the minimum cross-section of material between adjacent input holes being at least twice the minimum cross-section of material between such input holes and the output hole. The core may comprise a disc of uniform thickness, the input holes being elongated and separated from the disc periphery and the input hole by equal cross-sections of material. Pulses of current sufficient to saturate these cross-sections are passed through the input windings. An output in winding 34 is derived from an input A.C. winding 32 passing through hole 20 by changes of direction of the flux in the material surrounding hole 20. Such signals can pass when all the interhole crosssections are saturated in the same direction round hole 20, but blocked when the directions in two cross-sections are opposite. The direction of saturation is determined by the direction of the last pulse through the associated input hole. Saturation of material between input holes and the disc periphery prevents flux from currents in the A. C. winding and input windings 24, 26, 28, 30 from embracing two holes to produce spurious results. The device may act as a gate which is opened by application of pulses of like polarity, or as a control device which discriminates between pulses in one input winding of the same and of opposite polarities as setting pulses in the other three windings.

Title: Improvements in or relating to slicing machines
IPC: B26D1/143
Filed: 1931-01-19
Abstract: 371,359. Slicing-machines. HOBART MANUFACTURING CO., Troy, Ohio, U.S.A. - (Assignees of Johnston, H. L. ; Troy, Ohio, U.S.A.) Jan. 19, 1931. No. 31148. Convention date, Jan. 23, 1930. Divided on 371,350. [Class 28 (ii).] In a slicing-machine of the kind wherein the article to be sliced is pushed against a gaugeplate or fence which is slidable on the base to permit slice-thickness adjustments, the guides or tracks along which the gauge-plate is slidable are designed to exclude juices or particles from the interior of the base, and the base has a flexible sealing strip which accommodates itself to the irregularities of the table or other support for the machine, and thus excludes the entry of juices and particles at the bottom of the base. As shown in Fig. 3, the gauge-plate 98 is carried by a frame 97 secured to a sliding member 83, 84. The top of the base 10 is cut away to accommodate the portion 84 and guides thereon co-operate with guides on the underside of the base top. The portion 83 has a close sliding fit at its sides with flanges upstanding from the base, and the slice-receiving tray 140 prevents the ingress of juices &c. through the cut-away portion of the base top. The flange 141 at the end of the tray seals the space under the gauge-plate frame. The bottom rim of the base is recessed to receive a rubber sealing strip 12. The guides for the gauge-plate are arranged obliquely as shown in Fig. 2, so that, as the plate is retracted from the knife to increase the slice thickness, the space between knife edge and the edge of the gauge-plate is increased to permit the passage of the slice. The adjustment of the gaugeplate is effected by a graduated knob 105 on a shaft carrying a cam 118 which operates the bell crank 124. The end of the bell crank is forked at 133 and engages an eccentric bolt 135 on the slide whereby zeroizing adjustments may be made. A spring 95 tends always to move the gauge-plate towards the back of the base. A spring 120 urges the shaft 108 to the right, Fig. 4, to take up play in the adjusting mechanism. The cam groove 119 has a progressively varying pitch so that when thin slices are being cut, a given angular movement of the knob produces a smaller movement of the gaugeplate than it would when thick slices are being cut. The gauge-plate 98 has rear lugs 150 which slide on bars 151 to effect adjustments of the plate. Bolts 155 are screwed into the bars and are tightened to clamp the plate. The driving motor is mounted on a hollow pedestal 14 upstanding from the base and the slicereceiving tray has a flange 198 which abuts against the pedestal on two of its sides. The space between the flange 198 and the pedestal is sealed against ingress of grease &c. by a a plastic filling material, such as gypsum. The motor switch 248, 249 is housed within the base. Specification 371,350 is referred to.

Patent GB-637342-A (GB)
Title: Improvements in the manufacture of cellulose propionate
IPC: C08B3/28
Filed: 1947-11-28
Abstract: Cellulose propionate is purified by fractional precipitation from acetone solutions by addition of aqueous ethyl alcohol of concentration such that at the temperature at which the precipitation is performed the addition of a small proportion of the precipitant causes the precipitation of a small proportion only of the cellulose propionate over substantially the whole range of cellulose propionate concentrations between that of the acetone solution before the precipitant is added and about one-tenth of that concentration. Preferably the precipitation is carried out at about 30 DEG  C. by means of 52-62 per cent aqueous ethyl alcohol (by volume).  The concentration of the acetone solution should be about 10 per cent. Three or more fractions are usually obtained.  The first 10-20 per cent precipitates as a gel and is preferably reprecipitated by heating the solution and precipitate to about 40 DEG  C. until the precipitate just redissolves and then cooling.  The supernatant liquid is decanted and sufficient precipitant added to precipitate all but about 5-10 per cent of the cellulose propionate originally in solution.  This middle fraction is granular and may be filtered off and is found on moulding to be of high clarity and blush-free.  The concentration of ethyl alcohol is highly critical: both below and above the range 52-62 per cent by volume, sharply defined solubility points are observed making closely controlled fractionation impossible.  In an example, to 700 parts by weight of a 10 per cent solution in acetone of cellulose propionate containing about 0.3 free hydroxyl groups per glucose unit is added about 730 parts by weight of 57 per cent ethyl alcohol. After warming to 40 DEG  C. the mixture is allowed to cool to 30 DEG  C. and to stand, allowing a gelatinous precipitate to settle out. The liquid is decanted therefrom and 1800 parts by weight of the alcohol added, precipitating 75 per cent of the cellulose propionate as flakes, which are filtered off and dried. Acetone and ethyl alcohol are recovered from the third fraction, the ester therein being discarded.  Specification 345,408, [Group IV], is referred to.
