Filed: 1950-05-26
Abstract: 694,572. Clamps. MARTIN, V. May 26, 1950, No. 13332/50. Class 44 [Also in Group XXX] A lock for a cable cord or line under tension consists of a base plate which carries a pivot, on which is mounted a two-armed lever having unequally long arms and an upstanding abutment fixed adjacent the shorter arm, the arrangement being such that the cable may be passed over the end of the longer arm of the lever and between the abutment and the shorter trailing end, and the cable engages the end of the longer arm of the lever so as to rotate the lever causing the end of the shorter arm to grip and lock the cable with a force greater than the tension in the cable. As shown, a base plate 36 which may be formed as a wall plate carries an abutment 42 and a pivot 45 on which is mounted the lever 46. The cable passes downwards from. the overhead pulley of a kitchen appliance, under the longer end of the lever and between the shorter end of the lever and the abutment, the two ends of the lever being formed with grooves to locate the cable. A raised portion 41 of the base limits movement of the lever. In the preferred form shown the plate 36 is rotatably mounted in a wall plate 30, a pin 39 locking the former in position. By pulling out the pin 39 plate 36 is rotated by the tension in the cable and caused to release the latter.

Title: Improvements in or relating to the production of cellulose by the decomposition of non-lignified parts of plants
IPC: D21C3/02
Filed: 1948-05-18
Abstract: Cellulose suitable for paper-making is obtained from non-lignified plants, such as straw of cereals, grasses, oil seed plants and bagasse, by digesting the material, with or without a preliminary washing with water, for a maximum digesting period of 2 1/2 hours with a "sulphate liquor" containing 35-45 grams of caustic soda and 8-10 grams of sodium sulphide (Na2S) per litre, the total amount of alkali (NaOH + Na2S) used not exceeding 23 per cent by weight of the air-dry weight of the material being treated, at a substantially constant temperature of 140 DEG  to 150 DEG  C.  In the case of non-lignified plants such as bamboo which contain a high proportion of encrusting substances, the process is modified by using a "sulphate liquor" containing 68-80 grams of caustic soda and 12-15 grams of sodium sulphide per litre, the total amount of alkali not exceeding 23 per cent by weight of the air dry weight of the material being treated, and by digesting at a substantially constant temperature of 155-160 DEG  C. for a maximum digesting period of 2 1/2 hours.  The total time for heating to the required temperature and digesting at that <PICT:0667062/IV (a)/1> temperature is preferably not more than 4 1/4 hours.  The material is preferably heated to the required temperature as quickly as possible and the digestion liquor may be preheated. The waste lye (black liquor) may be treated, e.g. at 90-100 DEG  C. with an oxide or hydroxide of calcium or other metal so as to precipitate silicates, and after these have been removed by decanting, centrifuging, or filtering, the lye may be regenerated and re-used.  The pulp obtained may be bleached with hypochlorites, chlorites, chlorine dioxide, or chlorine.  Examples describe the treatment of wheat straw, bamboo, Sabai-grass, and bagasse.  As shown, cellulosic material is treated with white liquor fron tank 2 in a vertical rotary digester 1, and after the digestion is completed the contents of the digester are blown to tank 3.  Waste black liquor may enter through pipe 7.  The mass is pumped through defibrator 9 to one or more filters 11.  The pulp is washed on the rotary filters and then passed to stuff-chest 12 and to screens and beaters.  Strong lye from the filters passes to tank 14, overflow passing to the regenerating plant.  The precipitating and separating device for silicious impurities comprises vessels 16 with stirrers and heaters and container 19 for the lime or other precipitant.  The liquid passes to a clarifying tank or thickener 20 from which the transparent decanted solution passes to a soda house 21.  The carbonate is dissolved in tank 23 and causticized with lime in tank 24.  Sludge is removed in filter 25, and white liquor is passed to tank 2. Specification 459,790 is referred to.

Title: Improvements in or relating to closure or partitioning devices
IPC: E05D15/10
Filed: 1961-04-13
Abstract: 925,760. Sliding-doors. COMPAGNIE DES MACHINES BULL. April 13, 1961 [April 14, 1960], No. 13412/61. Class 20 (3). [Also in Group XIV] Sliding closure or partition panels present, in the closed position, a continuous rail along which any panel which has been displaced from the closed position can run. Each panel 11 is carried on rollers 72 on rails 74, 132 which are displaceable to bring the panel from the closed position into the running position and the rails 74, 132 into alignment with the rails 41, 51 carried by adjacent panels. Two superposed panels 11, 11A may be freed to move together along the rails by operating a latch (Figs. 19, 20, 22 and 23, not shown), to release springs 82 controlling parallel links 77, 78. The links turn about shafts 79, 80 and move the panels 11, 11A outwardly and downwardly. The downward motion releases a latch 150 (see also Figs. 12 and 18, not shown), which enables parallel links on shafts 140 and 141 to move the lower ends of the panels outwardly under spring action. The rails 74 and 132 occupy the positions previously occupied by the rails 41 and 51 and thus enable the two superposed panels to be run off into superposition with a third panel. By repeating the process, any number of panels can be stacked and carried pick-a-back by the innermost panel to any position along the rails. Superposed panels are locked together by a pawl arrangement (Figs. 5 and 6, not shown). The innermost is freed from the lock, on being manually pressed inwardly to retract rails 74, 132, by engagement of member 101 with its pawls. A lock 114 (see also Figs. 8 and 9, not shown), secures the upper latch which co-operates with an arm on shaft 79. A plunger (Figs. 10, 11 and 13-15, not shown), which prevents the panel from being moved when in the closed position, automatically engages the panel in this position. The panels form both side closures for an electronic computer cabinet.

Filed: 1966-03-28
Abstract: 1,112,202. Thermo-particulate analysis of organic nitrogenous materials. GENERAL ELECTRIC CO. 28 March, 1966 [29 March, 1965], No. 13568/66. Heading B1X. Organic nitrogenous materials are detected using a condensation nuclei detector 14 by pyrolytically converting the nitrogenous material in an oxygen atmosphere to nitrogen dioxide, chemically reacting the nitrogen dioxide with water to form nitric acid, reacting the acid with a substance capable of donating an electron pair to form therewith a salt of which the particles can act as condensation nuclei, and detecting the condensation nuclei produced with the detector. Preferably the nitric acid is reacted with ammonia to form ammonium nitrate particles to act as condensation nuclei, the water and ammonia being provided separately or as an aqueous solution of ammonium carbonate. Alternatively, the nitrogen dioxide is passed through a humidifier and the nitric acid so formed is then passed over solid ammonium carbonate and reacts with the ammonia gas given off (Fig. 2 not shown). The nitrogenous material is preferably filtered prior to being passed to the pyrolyzer, and is also filtered after pyrolysis to remove any carbon particles.

Title: Improvements in or relating to the manufacture of hollow plastic articles
Inventor: HINTON JAMES JONES
IPC: B29C51/10
Filed: 1962-04-10
Abstract: 954,820. Moulding hollow articles, e.g. balls. DUNLOP RUBBER CO. Ltd. March 29, 1963 [April 10, 1962], No. 13694/62. Heading B5A. In a method of moulding hollow articles, e.g. table tennis balls, a sheet of thermoplastic material 37 is held against each side of a heated platen 15 by the action of suction through passages 24 and also by externally movable heating boxes 27, the platen being either planar on both sides or having outwardly extending dies around which the heated sheet is drawn by suction. When the sheet 37 has been so treated the heaters 27 are moved away by piston and cylinder arrangements and the platen 15 moved along a rail 17 by a cable 21, connected to a piston 20 to bring it between two forming tools 1 enclosed in movable boxes 4, each forming tool 1 having at least one cavity 10. The boxes 4 and tools 1 are then moved into contact with the opposite faces of the platen 15 and a pressure differential applied in the cavities 10 through passages 12, and also in the platen 15 so that the plane or partially formed sheets are caused to take the form of the cavities 10, which in the example described are hemispherical shells. The platen 15 is then withdrawn and the boxes 4 moved into mutual contact, air introduced into them so as to pressurize the internal parts of the formed hemispherical shells, these latter then being joined together to form whole balls by further moving the tools 1 together against the action of springs 8. The edges of the tools 1 have special edges 11 to trim the half shells and to separate them from each other.

Title: Improvements in and relating to the separation of coal and the like
Filed: 1933-05-11
Abstract: 421,401. Separating coal. APPLEYARD, K. C., Birtley Springs House, Birtley, and BIRTLEY CO., Ltd., Birtley, Co. Durham. May 11, 1933, No. 13721. [Class 72] In the separation of pieces of coal from like fragmentary materials such as stone, the materials are fed on to trays 1, forming part of an endless band, the trays being supported at one side on rollers 2 running on an horizontal rail 6, the other side of the trays being hinged at 7 to a frame 3 which includes a V-shaped roller 4 traversing longitudinal guides 6. The endless band passes over wheels 8 having recesses 9 which engage necks 10 on the frame 3, one wheel 8 being driven by a chain 8<b> from a driving wheel 8<a>. A curved rail 11 receives the roller 2 when the part 12 of the rail 6 is withdrawn by the movement of the core 13 of a solenoid 14 when energized, allowing the tray 1 to move about the pivot 7 to deposit the piece of material into a shoot 15. If the part 12 is not withdrawn the piece of material passes on and is deposited in a shoot 16. Mounted above the endless band are a pair of comb-like contacting devices 17, 18 having flexible fingers 19, 20 and another device 22 having flexible fingers 24, a second device 23 having flexible fingers 25 being mounted below the tray 1. The contacting devices form part of a circuit including an amplifying device 26, the solenoid 14 and a transformer 33. If a piece of material 21 passing along on its tray 1 is conductive, it will when it comes into contact with the contacting devices, vary the voltage of the grid 38 of the amplifying device 26 and thus close the solenoid circuit energizing the solenoid 14 and thus cause the withdrawal of the part 12 of the rail 6. This will cause the tilting of the tray 1 about the pivot 7, the roller 2 thereon traversing the curved rail 11. In a modification, Fig. 9, single pieces of material are fed onto an endless band 43 and thence into an inclined shoot 45 contacting on its passage down the shoot with devices 19, 24, the solenoid 14 being connected to a hinged flap 44, and when energized withdrawing the latter to the passage 44<a>, allowing the piece thereon to be deposited into the shoot 16. The flap 44 may be mounted so as to be moved upwards instead of downwards or to close the entrance to one or other of two side shoots. In a further modification, the trays 1 are mounted so as to rotate about a central point, being hinged to a central carrier, the rollers 2 running on a fixed circular path except at the point just after they have come into contact with the devices similar to the devices 17, 18, where a curved path similar to the path 11 is provided. The treatment may be carried out in two stages which in the case of coal comprises separation into pure coal or stone on the one hand and substantially pure coal or stone plus laminated material on the other, the second stage comprising the treatment of the latter material into pure coal or stone and laminated material.
