Title: Apparatus and method for treating cellulosic material
IPC: D21C1/00
Filed: 1962-07-17
Abstract: 1,009,765. Treating pulp. BLACK-CLAWSON CO.Inc. July 17, 1962 [July 17,1961], No. 27417/62. Headings D2A and D2W. Apparatus for treating cellulosic material in the preparation of pulp comprises a tapered perforate casing 65, a co-operating feed screw 60, and a pipe 70 extending from the discharge end of the feed screw which pipe has a cross-sectional area over the greater part 72 of its length which is less than the annular area between the feed screw at its discharge end and the casing 65. Cellulosic material e.g. wood chips, fed through the apparatus is compressed between the flights 62 of the screw and the casing 65 sufficiently to exclude substantially all voids and liquid. Upon discharge from the end of the feed screw 60 the material is enabled to expand slightly in the tapered region 71 of the pipe 70 without exposing it to the atmosphere or liquid before being recompressed into a substantially solid plug of material in the pipe 72. This plug of material is discharged inside a frusto-conical housing 75 into which treating liquor may be admitted through inlet openings 77. The action of compression, expansion and recompression which takes place upon the fibres in passing through the unit is effective in causing defibration of the cellulosic material. Plant is described and shown in Fig. 1 incorporating two such feed screw units 20, 26 as described above. Wood chips from a hopper 10 are fed by a metering screw conveyer 12 to a mixing conveyer 13 in which the chips are pretreated with caustic liquor admitted through inlet 17. The pretreated material is fed into a feed screw unit 20 in which a substantial proportion of the natural juice of the material together with the caustic liquor is removed and passed to drain. The unit 20 discharges into an inclined digester 22 the material being immediately submerged under caustic liquor thereing when discharged from the feed screw unit 20. A further feed screw unit 26 removes a substantial proportion of the liquor from the material which then passes by means of conveyer 27 to the next desired station of treatment, e.g. defibring apparatus not shown.

Title: Improvements in stock distribution systems
IPC: F25D25/04

Abstract: 661,860. Dispensing articles on conveyers from cold storage. PUNCH ENGINEER.- ING PTY., Ltd. Oct. 14, 1949 [Oct. 14, 1946], No. 27548/47. Class 116 [Also in Groups XIII and XXX] In a system for dispensing articles a refrigeration chamber includes means for the storage and release of articles, incorporating means to prevent the articles freezing to each other and to the storage and releasing means, with means to convey the articles from the chamber to a predetermined locality. The articles are stored in a refrigeration chamber 1 on movable belts 2 and can be selectively released by driving these belts as required from a common driving means 17 through clutches 15, the articles falling from a belt 2 to a collector belt 3 over a flap 9 and being conveyed by the belt 3, which is driven through a clutch 16, to a shoot 7 in the wall of the chamber. Selectivity is achieved by operating one or more of a number of keys each of which energize a different electromagnet to engage a different clutch 15. Every such key when operated also causes the engagement of the clutch 16, a slow-release relay being introduced to cause the belt 3 to go on moving after the belt 2 has stopped, thus ensuring all the collected articles are discharged. The articles are loaded on the belts 2 through a door 4. The shoot is normally closed by a flap 8 which opens automatically whenever articles are released from the belt 3. The flap 9 may be raised by a device 19, comprising a solenoid and plunger, so that the articles cannot leave the belt 2 which then passes beneath them, and cleats spaced along the belt joggle the articles and prevent them from freezing together and to the belt, this operation recurring under the control of a timing device 14, which also operates the beltdriving clutches. The timing device 14 is governed by a bi-metal strip which opens and closes contacts as it bends due to alternate heating and cooling. The strip is heated by a coil the circuit of which is alternately closed and opened and includes a contact operated by a relay which is operable only when no selection of articles is being made and has a time-delay to ensure that a selection of articles is completely finished before the timing device 14 comes into operation. As the articles pass over the flap 9 they operate contacts 10 thereon which can be used to count the articles and to interrupt the circuit of the corresponding clutch 15 when the required number has been discharged. The flap 9 and contacts 10 are enclosed in an air-tight rubber envelope to prevent the contacts from freezing up. The shoot 7 may be dispensed with and the collection belt 3 may pass through the wall of the chamber, the opening being normally closed by a flap Instead of a collector belt a chain of receptacles may be used with an opening in the wall of the chamber just big enough to pass them. Specification 636,973 is referred to.

Abstract: 422,895. Cycle brakes. BENNETT, F., 16, Bramhall Lane, Stockport. Sept. 29, 1934, No. 27934. [Class 136 (i)] In a foot brake for pedal-propelled cycles, of the type in which a brake lever is operated by the heel of the rider's foot, the brake lever 7 has a rigid arm 16 projecting at an angle from a part of the lever which is lower than the fulcrum 10, so that the distance of the point of application of force to the lever measured from the fulcrum is approximately equal to the distance from the fulcrum of the point 6 of transmission of force by the lever, whereby a powerful braking action may be obtained with little effort. The fulcrum end of the lever 7 is forked to obtain a double bearing of the lever on the pivot bolt 10, the forking of the lever being central for use with a rim brake 4, 3, or offset for use with a hub brake. The lower end of the lever 7 is connected to the brake stirrup 4 or to the hub-brake cam by means of a rod 5 of telescopically adjustable length. The lever 7 is pivoted to a fixed lug on the down tube 1, or to a clip 11 having a block between its lugs for the passage of the pivot bolt 10, the coils of a torsional brake-release spring 15 being mounted on the bolt.

Abstract: 1280541 Clamps ENGLISH ELECTRIC CO Ltd 29 May 1970 [3 June 1969] 27946/69 Heading E2B [Also in Division H2] A fastening device comprises an L-shaped metal bracket 1 having walls 2 and 3, and an apertured metal block 7 which, when the screw 6 is tightened, forces a blade member 12 onto the wall 2. The block 7 pivots about its edge 9 which is restrained by the angle between the wall 3 and a shoulder 10 outstanding therefrom. Thus, by slackening the screw 6 the blade member 9, which may be a fuse tag, may be inserted into position, and subsequent tightening of the screw ensures good electrical contact between the tag and the wall 2. The walls 2 and 3 may alternatively be separate members, and the shoulder 10 may be replaced by an aperture in which a projection on the block 9 may be pivotally rotated, or by a radiused projection on wall 3 which contacts a complementary radius at the edge 9. The surfaces 14 and 15 of the block 7 may be at right angles, and the bracket angled to provide the necessary pivotal motion of the block.

The hydrogen and carbon monoxide obtained by the gasefication may be passed over a catalyst for conversion of the carbon monoxide into methane, the resulting gases with a reduced carbon monoxide content, and heated by the reaction, being used in the hydrogenation process. Coal is subjected to hydrogenation under pressure by the process described in Specification 503,183 in vessel 1, and the hydrocarbon gases pass by duct 2 to a gas holder 3, tar and liquor being withdrawn through outlet 4. The residue from vessel 1 is then transferred to vessel 5 in which it is gasefied by oxygen and an excess of steam under pressure from pipe 9. The gases pass by a pipe 6 partly through a pipe 7 to the vessel 1 for the hydrogenation of a further batch of coal, and partly by a pipe 8 to the gas holder 3. The apparatus may be modified so that the two operations may be conducted in the same vessel, these vessels being duplicated.
