Abstract: 286,933. Capiau, G., Gauquier, M., and Lahaut, L. June 7, 1927. Repairing - apparatus. - Cracks in the brickwork of ovens are filled while the oven is hot by supplying dry refractory material under air pressure to the seat of injury where it is set by the heat. For temperatures of from 600‹ to 1200‹ C. the refractory mixture may be 80 per cent (or cement and slag), 1 to 4 per cent dextrin, 2 to 7 per cent litharge, 3 to 8 per cent sodium chloride and 2 to 5 per cent sodium carbonate. Silica, or silicates may be added when glazing is desired. The material is supplied to a valved hopper 18 whence it passes through the valve 16 to a mixing chamber 1 with rotating stirrers 5. This chamber is supplied with a perforated false bottom 3 having an aperture 4 at one side adjacent to the exit tube 21 through which the dry mixture is blown by an air pressure tube 20 disposed under the false bottom. The refractory mixture passes along a tube 24 to the seat of injury, this tube having a jacket tube 25 through which air may be circulated to protect the inner tube from the heat; or the jacket may be fed with cooling water circulated by an injector 41, Fig. 3.

Title: Sustained release pharmaceutical compositions
IPC: A61K9/20
Filed: 1965-04-09
Abstract: A sustained release coated pellet or tablet containing a pharmaceutically active ingredient soluble in the fluids of the gastro-intestinal tract is coated with a layer comprising one or more areas impermeable by said fluids and pharmaceutically active ingredient and one or more other areas provided by a dialysing membrane permeable by said fluids and pharmaceutically active ingredient.  The dialysing membrane may be formed from a natural or synthetic film-forming material, e.g. cellulose acetate, collodion, acrylic, or phenolic polymers, but preferably from an ion exchange resin, e.g. sulphonated polystyrene, resorcinol-type resins, carboxylic acid resins, phenolformaldehyde polyamine resins, polystyrene polyamine resins, or polystyrene quaternary amine resins. A pH buffering substance capable of maintaining the pH at the surface of the tablet at or below about 7.3 may be incorporated in the tablet.  In one form, the medicament may be enveloped in a porous membrane, the outer surface of which is coated in selected areas with a layer of impermeable material.  In another form, the medicament may be enclosed in an impermeable plastics shell having a number of passageways passing therethrough which are sealed by dialysing membranes.  In a modification, the medicament may be sealed by the dialysing membranes in passageways passing through an impermeable plastics body, e.g. of polymethyl methacrylate or polytetrafluoroethylene.  In yet another arrangement, the active ingredient is coated with a dialysing membrane and encased in a rigid plastics jacket having a number of apertures therein.  The pharmaceutically active ingredient may be in liquid or powder form. Specified active ingredients comprise antibiotics, e.g. oxytetracycline hydrochloride, sedatives, and vermifuges.

Title: Improvements in or relating to multi-colour pencils
IPC: B43K24/12
Filed: 1949-06-08
Abstract: 661,723. Pencil holders. SCHMIEGLITZ, W. June 8, 1949, No. 15312/49. Class 146 (iii). A pencil holder is provided with a plurality of spring-controlled lead-holders each comprising an actuating bar by means of which it is movable within a common casing from a retracted position into a projected position, and a starshaped latch member centrally mounted within the casing and adapted, upon movement of any one of the lead-holders to projected position, to be first tripped by one of two shoulders on the actuating bar of said holder for release of any previously projected holder, and then to engage the other one of the two shoulders of said actuating bar of said projected holder, thereby to retain same. Each lead-holder comprises a flat bar 6 slidable in a longitudinal slot 20 in a core 2 fitted tightly into a casing 1, the slots being axially curved, such that the lead-holders are brought into an axial position coinciding with the axis of the casing when projected. The lead holders are projected by actuation of knobs 19 slidable in slots in the sleeve 1 against the action of springs 11. A latch 13 having upturned projections with slanting edges 14, is rotatably mounted on the lower end of the core 2 and is normally held in the position shown in Fig. 9 by a U-shaped spring 16. Projection of a lead-holder causes a shoulder 15 on its bar 6 to engage and rotate the latch 13 and so release the previously projected holder which then returns to a retracted position. Further projection causes the latch 13 to engage an upwardly facing shoulder 30 on the bar 6 and so retain the holder in projected position. The core 2 is provided with a storage space for the spare leads 17. Individual leads may be projected by turning a tubular element 9 journalled in a member 8 hinged to one of the bars 6, the upper end of the member 8 being internally threaded to engage external threads on a push rod 10 held against rotation by a flat on the member 8.

In a railway car retarder of the track brake type wherein braking bars are located adjacent the track rail and are arranged to be moved into engagement with a part of the railway car for retarding the speed of the vehicle, braking bars 21 provided with removable brake shoes 22 are adapted to be moved into frictional contact with the railway vehicle wheel 24 by pressurization of fluid pressure cylinders 15a, 15b which extend substantially the whole length of the braking bar. Two types of fluid pressure cylinders are illustrated in Fig. 1; 15a shows a cylinder of rectangular shape receiving a rectangularshaped piston 17 and a moulded rubber fluid bellows 18. When the latter is supplied with compressed air through connection 19 the bellows expands to urge piston 17 and braking bar against the vehicle wheel 24. 15b shows a cylinder of elliptical shape provided with a similar shaped piston 28 and a cup-shaped rubber diaphragm 29 which at all times bears against the piston 28 and is secured to the body of the cylinder housing. The fluid pressure operated piston cylinder devices 15a, 15b and braking bars 21 are so arranged and proportioned that each braking bar is normally biased by gravity to the non-braking position. A plurality of retarder bars 21 and applying cylinders 15a, 15b are provided on both sides of the rail 10 as shown in Fig. 2.

In an apparatus for sorting bodies of a material having a non-insulating constituent, such as in sulfide ores, which bodies are constrained to be conveyed in a single line or a wide path random stream, and preferably under the influence of gravity, through a sorting zone, an arc discharge current between two electrodes initiated by the movement of a body past the electrodes is used to control a rejection means whereby a body is directed into an appropriate one of two desired paths. The rejection means comprises a nozzle, for directing a blast of air at the appropriate time, situated below the detecting zone. The fragments or bodies are fed to a trajectory plate by a vibrating table and the electrodes are mounted by brackets in a row beyond the end of the trajectory plate, alternate ones being connected and grounded. In alternative arrangements plate electrodes or helical spring electrodes may be used in co-operation with a conductive trajectory plate. Specification 986,177 is referred to.

Abstract: 624,772. Projection screens. DU MONT LABORATORIES, Inc., A. B. May 24; 1946, No. 15843. Convention date, June 12, 1945. Drawings to Specification. [Class 97 (i)] The screen comprises a flexible plate having a smooth light-reflecting surface with flexible lenticular transparent elements attached thereto. In one form, a metal base is sprayed first with a lacquer and then with a solution of a transparent substance which may be the same as that from which the lacquer is produced. The latter solution, however, is of such concentration, and sprayed with such an air supply, that the droplets are nearly solid on striking the base and embed themselves in the lacquer layer to form lenticular elements. This lacquer may be opaque to prevent passage of light between adjacent elements. The whole screen may be coated with a lacquer of different refractive index from the substance of the lenticular elements, to form a smooth surface over them. The screen may be bent to give the best light distribution to the spectators, during which bending the lenticular elements are also distorted.
