Title: Improvements in and relating to solutions of cellulose esters
IPC: C08L1/10
Filed: 1922-07-01
Abstract: Liquid sulphur dioxide, preferably free from moisture and other impurities, is employed as a solvent for cellulose esters.  The process is best carried out under pressure, and the solutions may be employed in the manufacture of artificial silk, photographic films, and the like.  The solvent is removed by reducing the pressure and if necessary, raising the temperature, a tougher and more elastic product being obtained if this operation is performed in a closed system where no moisture is present.  The process is particularly applicable to cellulose acetates and nitrates, or to mixtures of these esters.  The solution of an ester in sulphur dioxide may further be treated with a liquid in which the ester is not initially completely soluble, such as an aliphatic alcohol, carbon tetrachloride, pentachlorethane, dichlorethane, amyl acetate, gasoline, benzine, turpentine, and chlorinated oils, when it is found that on evaporating the sulphur dioxide the ester remains in solution in the added menstruum.

Abstract: 963,871. Measuring electrically. NIPPON ELECTRIC CO. Ltd. May 9, 1963 [May 16, 1962], No. 18356/63. Heading G1N. [Also in Division H4] A radio pill comprises a container for a substance reacting to blood and a device capable of a change of state in response to the reaction which is incorporated in the radio pill in such a way as to modify the signals transmitted thereby. The arrangement is used to detect bleeding in a digestive organ and is based upon the fact that an enzyme called catalase is present in blood which acts as a catalyst for the decomposition reaction of hydrogen peroxide, the resulting steep temperature rise or pressure change being used to detect the blood. Since hydrogen peroxide is liquid at normal temperatures it is not readily usable and in the embodiment described a solid such as sodium peroxyborate is used. The radio pill 1 includes a thermistor, a thermo-couple or a heat sensitive capacitor, and a removable capsule 3 which contains sodium peroxyborate and is provided with a reticulate window 4 allowing the blood to come into contact with the contents. In a modification for use when it is known that the bleeding region lies beyond the stomach the window 4 is covered by a layer of material such as formalin gelatin or cellulose acetate phthalate which is soluble not in the stomach but in the bowel. In a further arrangement in which the pressure change resulting from the oxygen produced by the reaction is detected, the container 3 is closed except for a non-return valve allowing the blood to enter but preventing the escape of the oxygen. The pressure-sensitive device may be a wire or semi-conductor strain gauge or a variable reluctance device.

Abstract: 1,003,598. Miscellaneous releasable fastenings. WILMOT-BREEDEN Ltd. May 6, 1964 [May 10, 1963], No. 18527/63. Addition to 993,147 Headings E2A. [Also in Divisions B7 and Fl] In an anti-theft device wherein a steering locking bolt 7 and key-operated ignition switch mechanism 20 are interlocked so that one cannot be operated until the other is in the inoperative position, and the locking bolt automatically returns to inoperative position when the key is turned in the direction opposite to that required to operate the ignition switch, the turning of the key in the said opposite direction is, if necessary, capable of producing positive retracting movement of the bolt. The bolt 7, carrying the bolt head 12 for engaging a recess in the steering column, has a slot 26 co-operating with a non-circular portion of the switch shaft 20 on which is pivotally mounted a pawl 23. In the retracted position of bolt 7, the shaft 20 is situated in a circular part of slot 26 with a flat 25 thereon aligned with a flat edge 27 of the slot 26, whereby bolt 7 can be pushed by an operating member inserted through opening 10 against spring 40 towards locking position in which it is held by a step 37 on pawl 23 engaging face 38 of a projection 35. In this position the edge 27 co-operates with the flat 25 to prevent the key being turned in the normal direction to close the ignition and starting switch. To release bolt 7, the key is turned in the opposite direction whereupon flat 24 on shaft 20 contacts projection 30 to rotate pawl 23 free of projection 35 to allow spring 40 to return the bolt 7 to inoperative position. If the bolt jams, the spring 40 becomes compressed to solid state and transmits the movement of shaft 20 positively to bolt 7 to force it positively to inoperative position. When the ignition switch is operative the flat 25 engages projection 30 to hold pawl 23 so that it cannot be moved aside by projection 35, preventing bolt 7 being moved to the locking position.
