Title: The production of chemical wood pulp
IPC: D21C5/00
Filed: 1939-04-11
Abstract: 527,415. Wood pulp. PANGARA HOLDING CORPORATION. April 11, 1939, No. 11015. Convention date, April 12, 1938. [Class 2 (ii)] Pulp suitable for the manufacture of white paper is prepared by subjecting unbarked woody portions, free from cork, of coniferous or deciduous trees to the action of a pulping chemical under such conditions as substantially completely to dissolve the non-cellulosic constituents. Tree growth covered with bark in which cork has not yet formed comprises in general the portions having a diameter not greater than 1¢ inches and a bark free from scale. Wood from fruit trees, and unbarked twigs of a diameter of not more than # inches may be employed. The woody portions may be crushed before being subjected to the action of the pulping chemical. In an example, primings are cut into lengths of about a foot, washed, and crushed down to “ inch thickness. The crushed pieces are then cooked with 6 to 8 per cent. caustic soda for 1 ¢ to 2 ¢ hours at a pressure of 110 to 115 lb. and a temperature of about 175 ‹C. The pulp is finally washed, refined, bleached, or otherwise treated.

Title: Voice frequency signalling system
IPC: H04Q1/446
Filed: 1962-03-23
Abstract: 949,556. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. March 23, 1962 [March 25, 1961], No. 11249/62. Heading H4K. In a system in which V.F. selecting signals are sent from a substation by means of a transistor oscillator Trs, the line is fed with A.C. of a frequency higher than the " keying " speed when the register is connected at the exchange in order to energize alternately the oscillator through rectifier Gs and the talking circuit through rectifier Gr. A capacitor C shunting the latter rectifier allows tones to reach the receiver F. In response to the A.C. the oscillator sends V.F. current which energizes a V.F. receiver EO. When a key such as Tx is actuated the frequency of the oscillator is changed and a signal is sent to operate one of receivers E1 . . . En, whereupon relay W replaces the A.C. by direct current for the duration of the signal. Relay WR controlled by the A.C. generator connects up the receivers only while the oscillator Trs is operative.

Filed: 1950-05-08
Abstract: 667,546. Auxiliary air admission. GUINCHARD, J. E. May 8, 1950, No. 11440/50. Class 7(ii) A stationary plate 2 disposed in operative association with the engine carburetter has an aperture 3 for the admission of auxiliary air to one end of a tube 4 connected at its other end to the interior of the induction pipe, the aperture 3 being operatively opened and closed during closing and opening movements respectively of the carburetter throttle valve 19 by means of the action of the valve 19 on superimposed plate valve elements 7, 8 rotatably mounted with mutual lost motion on the plate 2, the element 7 having an aperture 13 co-acting with the aperture 3 and the element 8 being an elongated strip of sufficient width to cover the aperture 13. The element 8 is rotated from the throttle valve operating lever 18 by a link 16 connected to an adjustably mounted arm 16x, and has a projection 15x engaging with considerable play in an aperture 14 in the element 7 to rotate it. During throttle opening movement, the element 8 covers the aperture 13, as shown in Fig. 4, throughout the passage of the latter across the aperture 3 and across a surface groove 3x communicating therewith. During throttle closing movement, the play between the members 14, 15x causes the element 8 to uncover the aperture 13 and the groove 3x and aperture 3 are thus uncovered therethrough in turn. When the throttle valve 19 is fully closed, the aperture 13 has passed beyond the aperture 3, and auxiliary air admission is prevented. The tube 4 is soldered to the plate 2. and communicates with the induction pipe through a flexible tube 5, which may be connected to the induction pipe at -the existing air entry thereto of a windscreen wiper suction tube, or independently thereof The elements 7 and 8 are preferably made of dissimilar metals, such as brass and steel. The plate 2 may be secured to the carburetter as by an existing bolt 20. Specification 652.930 is referred to.

Abstract: 795,869. Transfer paper. O'SULLIVAN, D. J., and LEFEBURE, E. April 13, 1956 [April 22, 1955], No. 11735/56. Class 96. [Also in Groups XV and XVI] In copy-reproducing processes of the spirit type, the transfer paper is coated with colourless complexes of a dye formed by combination of a dye, reduced dye, or dye intermediate with a non-ionizing salt-free surface-active agent, e.g. a long-chain alkylamiire or an ethylene oxide condensate, and the copy sheet in contact with the transfer sheet is coated or impregnated with an oxidizing agent-which develops the colour of the dye former transferred to the copy sheet by the printing &c, process. Colour formers specified are amino salts of the leuco dye obtained by reacting the leuco dye with a primary amine, e.g. stearyl or lauryl diamine. The salt may be formed in the wax employed as a constituent of the hectograph coating; alternatively an alkali salt of the leuco dye may be used. Suitable oxidizing agents are quinone derivatives, e.g. hydroquinone, or succinic acid derivatives, e.g. N-bromosuccinimide, Two component systems in which one reactant is mixed with the dye intermediate and the other with the liquid used for wetting the copy sheet may be used. In examples: (1) the stearylamine salts of amino leuco crystal violet are reacted with stearylamine at 80‹ C. and the complex formed is mixed with wax and a filler and used to coat a hectograph sheet; (2) the reaction is carried out in presence of the wax. In the above examples, the amine may be replaced by a polyethvlene-oxide condensate. A master is made from the transfer sheets and copy obtained from this master by a hectographic reproducing process is damped with a liquid having one of the following percentage compositions: (A) methylethylketone 99, chloranil 1; (B) methylethylketone 90, tetrachloroethylene 9.5, chloranil 0.5; (C) methylethylketone 80, tetrachlorethylene 9.5; dioxane 10, and chloranil 0.5; (D) methylethylketone 90, perchlorethylene 9.5, N-bromosuccinimide 0.5; (E) acetone 80, dioxane 10, trichlorethylene 9.5 and chloranil 0.5; (F) methylethylketone 90, tetrachlorethylene 9, p-nitrophenyl isocyanate 0.5, and chloranil; (G) methylethylketone 99, chloranil 0.5, p-nitrophenyl isocyanate 0.5.

Abstract: 294,712. Appleby, P. V. May 4, 1927. Heckling-machines; grip-chain and like arrangements for feeding, holding, and conveying fibrous materials. - In a machine for heckling fibres, particularly designed for the heckling of coco bristle fibres, the material is held by an endless conveyer travelling longitudinally of the machine and is gripped by pairs of wheels located on opposite sides of the conveyer whilst it is treated by heckling-devices adapted to comb the material transversely of the machine. The material is laid on the endless conveyer b, Fig. 1, comprising ropes or a leather or metal band, the feeding operation being facilitated by the use of racks of U-shape which span the conveyer. The fibre is carried between cast iron wheels d, d<1>, with rubber &c. tyres d<2>, situated to one side of the conveyer. The upper wheel is capable of vertical movement and may be weighted by a weight e and levers e<1>. The wheels are rotated at the same speed as the conveyer b. Whilst held by the wheels the fibre is treated by a rake f, Fig. 2, carried by a counterbalanced arm f<1>, operated by a crank g and supported by a link f<2> provided with a roller f<3> engaging a cam h. The material then passes between a second pair of wheels i, i<1> located on the opposite side of the conveyer and the other end is combed by a second rake. The pairs of wheels d, d<1> and i, i<1> may be arranged to overlap. The material may then be discharged or may be passed forward to further pairs of wheels to be treated by further heckling devices. The short fibres combed out by the rakes f are guided into hoppers k by discs l or by fans, &c. The treated material is passed forward by the conveyer b and is tied into hanks either manually or automatically by a device similar to that employed in a reaping and binding machine. The machine is driven by a motor m operating through a clutch n or loose pulley arrangement. Two electric motors may be used one driving the conveyer through worm &c. gear. ing and the other the rakes, fans, &c. through spur and chain gearing. The combs may be mounted on continuous chains.
