Title: A process for making cellulose combinations
IPC: C08B9/00
Filed: 1924-05-22
Abstract: Cellulose derivatives are prepared by reacting with ammonia on a cellulose xanthofatty acid or a salt of such acid, that is, on such products as are obtained when a monohalogen fatty acid or a salt or derivative of such acid reacts on a cellulose xanthic acid or a cellulose xanthate, for instance, as described in Specification 231,800, and particularly when the halogen fatty acid is monochloracetic acid, a -bromopropionic acid, a -bromobutyric acid or bromosuccinic acid.  The reactions between the halogen fatty acid &c. and the cellulose xanthic acid &c., and between the resulting cellulose xanthofatty acid &c. and ammonia may be carried out as separate processes, or they may be combined in one operation, that is, the ammonia may be added to the cellulose xanthofatty acid or alternatively to the cellulose xanthic acid either before, during or after the addition of the halogen fatty acid.  The treatment of the cellulose xanthofatty acid with ammonia may be carried out in neutral, alkaline or acid solution; the cellulose xanthofatty acid may be in solution, in the solid state, or in suspension, for instance, in alcohol; the ammonia may be used as a gas or in solution, and in excess or in amount equal to or less than the theoretical quantity; and the reaction may be carried out at normal temperature, or with heating.  The products are insoluble in water but soluble in aqueous alkalies, and are precipitated from their solutions by the addition of substances that neutralize ammonia, such as acids or salts, or by dehydrating agents; when precipitated in the form of threads or films, the products are strong, flexible and transparent.

Abstract: 722,736. Microscopes. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE OUDE DELFT. May 19, 1952 [May 18, 1951], No. 12660/52. Class 97 (1). In an interference microscope in which the beam for imaging follows the same path geometrically as that for obtaining the coherent background, the two beams are focused by splitting the condenser beam by a birefringent crystal plate provided between the condenser and the object or mounted in the condenser, whilst the beams are recombined by a birefringent crystal plate provided between the object and the objective or mounted in the latter. As shown, the plates Q1, Q2 are formed of uniaxial crystals cut parallel with the optic axis and are rotated relative to one another through 90 degrees. The axis of the plate Q1 is arranged at 45 degrees to the plane of polarization of light from the condenser and therefore splits the condenser beam into an ordinary beam o and an extra-ordinary beam e, both of which pass through the object V and its cover glass G but are focused at different planes, the ordinary beam at plane Ve and the extraordinary beam on the object. On reaching the second plate Q2 the ordinary beam of plate Q1 becomes the extraordinary beam of the plate Q2 and vice versa, the two beams being combined and an image of the object being formed in the eyepiece by the extraordinary beam of the plate Q2 while the plate Ve will not be focused in the eyepiece. Observation is effected through an analyser. In a modification the condenser beam is circularly polarised, the plates Q1, Q2 being suitably chosen accordingly and having interposed therebetween an optically active layer or two half-wave plates to rotate the planes of polarization through 90 degrees. Such a layer may be made achromatic.

Title: Improvements in and relating to the control of electric motors
IPC: H02P1/12
Filed: 1925-05-16
Abstract: 256,719. British Thomson-Houston Co., Ltd., and Salisbury, A. G. May 16, 1925. Switches, actuating. - In the control of small electric motors suitable, for example, for driving the turn-table of a gramophone, the motor is given an initial turn by hand and an automatic switch, in association with the motor shaft or a shaft driven thereby, then completes the motor circuit. In the arrangement shown in the Figure, a bridging contact-member 4 in the form of a quick-pitch nut co-operates with a screwthread 3 on the motor shaft. When the motor shaft is given an initial turn by hand the inertia of the nut causes it to move to the end of the spindle against the action of gravity or a spring. In this position the bridging annular contact 5 closes the motor circuit and the nut 4 revolves with the spindle. When the motor is stopped or the speed very much reduced, the nut moves inwards again and the motor circuit is broken.
