Title: Process for removing cellulose-containing impurities from wool and woollen fabrics
IPC: D06M11/81
Filed: 1957-10-04
Abstract: Cellulose-containing impurities such as cellulose acetate, regenerated cellulose and/or natural cellulose, are removed from wool and woollen fabrics by treating the wool or mixed woollen fabric with anhydrous silicon tetrachloride or anhydrous boron trichloride, with substantial exclusion of moisture, and then removing the chloride from the treated wool or woollen fabric and removing the impurities mechanically in such a manner that the fibre structure of the wool is retained.  The anhydrous chloride may be used in the form of a gas or vapour or dissolved in an inert solvent, e.g. an alkyl halide such as trichlorethylene, carbon tetrachloride, chloroform or perchlorethylene, tetrahydrofurane, dioxane, ethyl alcohol, benzine or benzene, which may also be in the form of a gas or vapour.  The boron trichloride and silicon tetrachloride may also be used in the form of their oxonium addition compounds with ethers, which may be prepared by mixing the anhydrous chlorides with suitable ethers in an inert medium, e.g. a halogenated hydrocarbon.  The wool or woollen fabric is preferably treated with the anhydrous chloride in a quantity of 0.5 to 4% in relation to the weight of the textile fibres for 10-30 minutes at a temperature in the range from room temperature up to 110 DEG  C., squeezed and dried at 70-100 DEG  C. and the impurities removed by beating.

Abstract: 393,190. Board games. KELLER, W. and NEHMANN, E., (trading as FRANCKH'SCHE VERLAGSHANDLUNG W. KELLER & CO.), 5, Pfizerstrasse, Stuttgart, Germany. (Assignees of Patschkowski, H.) Nov. 8, 1932, Nos. 31547 and 31548. Convention dates, Nov. 9, 1931, and Oct. 25,1932. [Class 132 (ii).] In a game board provided with electric contacts which are closed by playing-figures or counters so as to close an electric circuit, an electric conductor having two or more interruptions is exposed in a number of positions on the board in such a manner that the circuit is closed when two or more figures or counters, corresponding to the number of interruptions, bridge the interruptions at a corresponding number of selected positions amongst these exposed positions. The board may consist of superposed sheets of pasteboard, the upper sheet of which is perforated so as to expose in each aperture, as shown in Fig. 1, a pair of electrical contacts formed by the limbs of a number of insulated metal strips N, P, X<1>, X<2>, X<3> arranged as shown in Fig. 4. The contacts are numbered consecutively and the strips N, P are connected to a dry battery and electric buzzer, bell, lamp, or optical signal attached to the underside of the board. In playing a game, metal playing pieces are moved from one numbered aperture to another according to the numbers thrown by dice, and bridge the contacts in the apertures. The arrangement of the contacts is such that closure of one pair of contacts by a playing piece is insufficient to complete a circuit, but closure of two pairs of contacts may (dependent on a predetermined combination being effected) complete the circuit and sound the buzzer, thus indicating for example that the playing piece must retire. In modified arrangements it is necessary to close three or more contacts in order to sound the buzzer. The box is provided with a compartment for storing the playing pieces.

Abstract: 449,899. Boat-launching gear. PAMPINELLA, A., Ministero della Marina, Rome. Nov. 3, 1934, Nos. 31650 and 31651. Convention dates, Nov. 10, 1933 and Sept. 24, 1934. [Classes 113 (i) and 115] Boat-launching gear comprises a pair of straight tracks 11 hinged at 33 to the deck. Normally, the tracks rest at an angle of about 30‹ on deck stools 27. Sliding gravity davits 1 rest on the tracks and are maintained inboard by the tackles 12 which are led over suitably disposed pulleys to the winch 22. Releasing the gear allows the davits 1 to slide down the tracks outboard. Finally the weight of the davits causes the tracks 11 to tip about their pivots 33 into a vertical position. The boats are then lowered to the water. The davits are combined with a gangway comprising the upright 41, Fig. 18, carrying the links 40, 47, which constitute the gangway proper. Links 43 working in guides 44 fixed to the deck and guides 45 fixed to the frame control the motion of the gangway. In a modification, the davit and supporting stool are mounted on a platform over the boat deck. In a modification of this type the track 11 may be swung outboard beyond the vertical position. In another arrangement the davits sliding on the track 11 are designed with two davit heads so that a pair of boats may be operated by the same pair of davits. The Specification as open to inspection under Sect. 91 comprises also a slip hook gear comprising a hook which automatically releases the falls when the boat is water-borne, combined with a sliding-frame which moves the hook opening until removed. This hook is combined with a hand-operated release device mounted in the lower part of the boat. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for measuring curved surfaces
Inventor: BUTLER GRAHAM JOHN
IPC: G01B11/255
Filed: 1960-09-16
Abstract: 926,506. Optical apparatus for examining curved surfaces. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 18, 1961 [Sept. 16, 1960], No. 31956/60. Class 97 (1). Optical apparatus for examining a curved surface comprises a first optical device adapted to reflect a light beam from a selected point on said surface through a right-angle along a reference line, means for indicating the position of the first optical device on the reference line and a second optical device adapted to reflect a light beam from the selected point through a known angle along the reference line, and means for indicating the position of the second optical device on the reference line. The apparatus is shown as applied to the examination of the paraboloidal surface 3 of a micro-wave aerial which is covered by a radome 4. It comprises a tube 2 attached to a container 7, the tube being mounted in apertures 5, 6 and the container being mounted in an aperture on a frame 8 so that the tube and container may be rotated together. Within the container 7 is an electric motor 17 driving a lead screw 12 to move axially of the reflector a carriage 15 for supporting a pentag prism 16. Also in the container 7 is a telescope 23 which is aligned with the reflector's axis. In order to determine the x co-ordinate of a point P marked on the reflecting surface 3, a right pentag 16 is placed on the carriage and the latter moved axially until an image of point P co-incides with the telescope cross-wires. By means of a suitably calibrated revolution counter 19 and dial 21, the x-co-ordinate of point P can then be read off. The pentag prism is then replaced by an angle pentag, which turns light rays, incident normally on one face thereof, through a known angle 0. Carriage 15 is again moved until the image of point P again coincides with the telescope cross-wires. The reading on the counter 19 and dial 21 then indicates the axial distance from the pole of the reflector at which a line drawn from P at an angle 0 to the reflector's axis will meet this axis, and the y-co-ordinate of point P may then be calculated. In this way, the x- and y-co-ordinates of several points P may be determined and by substitution of these values in the usual equation for a parabola (i.e. y<SP>2</SP>=4ax) it can be seen whether the surface is true and also an average value for the focal distance a can be calculated.
