Title: The manufacture of artificial coal or coal-like substances and by-products from vegetable matters or matters of vegetable origin
IPC: C10B53/02
Filed: 1923-05-26
Abstract: 216,691. Beaudequin, J. May 26, 1923. Carbonizing processes.-Artificial fuel is made from wood, brown coal, or peat, by disintegration, dehydration, partial distillation, compression and finally carbonization, by-products being recovered. Raw peat is disintegrated into a watery mud and caused to flow in channels provided with ledges to hold earthy impurities which sink to the bottom the mud like peat constituent being then filtered in porous vessels in which the water is separated and a felting or binding takes place. The powdered material is dried at a temperature of 150‹ C., then heated to 250‹ C. and freed from carbonic acid, acetic acid and pyroligneous acid, and the vapours, cooled in a tube g by a jacket i through which air is blown by a fan h, pass into condensers, acetate of lime being obtained. The permanent gases are burned in a furnace d and used for the drying and carbonizing. The dried product is briquetted into a press a, the pitch and tar constituents increasing the cohesion, and the resulting blocks are carbonized in a tube b maintained at 300‹ C., and pushed along by a, ram e to a cooling tube b<1>. Metal plates are inserted between successive blocks to act as heat distributors and prevent the blocks from sticking together. The hydrocarbons evolved combine with the material treated, and the gases and lighter products may be withdrawn by a pipe f and mixed with the distillates from the drying process. Petrol residues may be added to the material during the drying process. Light vegetable materials such as grass, leaves or moss may be decomposed bv fermentation, powdered and mixed with coal dust and subjected to the same treatment as the briquettes. When brown coal is treated, pyrites is deposited and may be employed for making sulphuric acid.

Title: Arrangement for varying the compression in piston steam engines, especially locomotive steam engines with poppet valve gear
IPC: F01L31/16
Filed: 1935-05-13
Abstract: 448,482. Engine valves and valve - gear. LENTZ, H., 74, Kurfurstendamm, Halensee, Berlin. May 13, 1935, No. 14040. Convention date, April 20. [Class 122 (ii)] To avoid undue compression in steam engines for locomotives &c. running at different speeds, the compression is commenced later or earlier as the speed is increased or decreased respectively through the adjustment of the axles of intermediate rocking-levers for the exhaust valves, which adjustment is made independent of the main control through normal regulating means. The adjustment is effected by hand or in dependence upon the travelling speed of a governor or by a servomotor depending upon the braking pressure when this is regulated by the speed. The insert piece 6 which accommodates the admission valve cage is secured in position by the tubular exhaust box 9 mounted on the end of the valve chest. A valve cage 10 houses the exhaust valve 11. A hollow cover 12 on the exhaust box 9 accommodates the cam gear for the valves. The admission and exhaust valves 8, 11 are opened by a shoe 13<a> on a shaft 13 through levers 14, 15 respectively and closed by steam pressure. The shaft 13 is oscillated by a link 16. The cams act as rolling levers and operate valve levers. The spindle 18 of the exhaust valve is hollow, surrounds the spindle 17 of the admission valve, and works in a bore 19 of cage 7 which communicates with bore 5 in the inset piece 3. Valve 11 is operated by a hollow thrust rod 20 mounted on spindle 18 and by the lever 15. The hub 23 of lever 15 is mounted on an eccentric pin 22 in the cover 12, which lever can be adjusted between positions a, b which show the positions for 50 and 100 kilometers per hour respectively. At high speeds the exhaust valves are opened earlier and closed later. The adjustment may be effected to facilitate starting. In a modification, where the cam is arranged centrally of the cylinder on the axis of the exhaust valves, the pivots 21 of the levers 15 are mounted on sliding blocks mounted in curved guides. In a further modification, the exhaust valve spindles are actuated by rollers mounted on the levers 15, the axes of which are adjusted in guides perpendicularly to the valve spindle axis.

Abstract: 960,941. Ingot moulds; mould and core materials. FOSECO TRADING A.G. March 21, 1963 [April 11, 1962], No. 14047/62. Heading B3F. [Also in Division B5] In a method of producing linings or hot tops for ingot moulds, a pulp slurry is made from a fibrous organic material and other solid refractory ingredients, e.g. waste newsprint, silica flow, asbestos, quartz, or calcined dolomite, mixed with excess of water, a thermosetting binding agent, e.g. both a urea formaldehyde and a phenol formaldehyde resin, being added to the aqueous slurry which is then charged into a moulding vessel having a wall (e.g. of wire mesh) which is permeable only to the liquid medium, the binding agent being precipitated from the slurry either before or after charging to the moulding vessel, the liquid medium then passing through the permeable wall leaving behind a compacted mass of the solid constitents of the slurry which is subsequently heated to dry them and to cure the binding agent. The binding agent is precipitated by adjusting the pH of the slurry, e.g. to pH5 by the addition of a sufficient quantity of sodium or potassium bisulphate. Air pressure may be applied to the slurry to aid the liquid medium to pass through the moulding vessel.

Abstract: 899,503. Shaft position digitizers. SMITH & SONS (ENGLAND) Ltd., S. April 14, 1961 [April 22, 1960], No. 14197/60. Class 40 (1). A shaft position digitizer comprises coding discs 8-11 of which disc 8 is driven continuously by the shaft 7 and discs 9-11 are driven discontinuously through Geneva mechanisms 12-14. Disc 8 has coding rings 8b-8d, Fig. 2, and a further ring 8a with twice as many marks as ring 8b (the least significant ring), each mark being centred on a mark or space of ring 8b. Gates 25 which receive the outputs of rings 8b-8d of disc 8 and all the outputs of discs 9-11 are arranged to pass these outputs only when a pulse from generator 24 applied to the sensing means for ring 8a produces a transfer pulse on line 27, i.e. when the output of disc 8 is not about to change. As depicted in Fig. 1, the discs comprise conducting and insulating areas and the sensing means 19a-19d, to 22a-22d are brushes, voltage being supplied to the discs over brushes 15b- 15d to 18a-18d. Brush 15a co-operates with brush 19a to apply a transfer pulse to gates 25 only when both brushes lie on a conductive area. Other forms of discs and sensing may be used, e.g. the sensing may be magnetic, capacitive or photoelectric. The fifteen digit binary coded signal passed by gates 25 is entered in a shift register 26 which is then read out by a serial train of fifteen pulses from generator 24. The output train of register 26 is recirculated to the register to guard against the next read-out indicating zero if gates 25 are not opened to enter a new indication before the next read-out train.

Abstract: 1,172,493. Photographic cameras. NIPPON KOGAKU K.K. March 25, 1968 [March 23, 1967 (2)], No.14379/68. Heading G2A. A photographic camera comprises a film take up mechanism and a shutter charging mechanism inter-connected by a clutch mechanism 16, wherein after closure of the camera back 24, the clutch remains inoperable until after a predetermined number of rotations of a film take up spool 14 have been made, so as to allow the winding on of the film leader strip without the necessity of repeated operation of the shutter. When a film is loaded into the camera, the leader is inserted into the take up spool 14 and the back 24 closed. The driving clutch piece 16 is held in the position shown by a spring 18, and closure of the camera back presses a controlling member 22 into contact with a screw thread 16a of the clutch. Rotation of a take up lever 4 is transmitted, via gearing and a ratchet 5 and pawl 6 to the shaft 12 of the spool 14. The driving clutch 16 is rotated by a pin 17 on the shaft 12, and is screwed downwards (as seen) while the film leader is wound on to the spool. Rotation is stopped when a projection 16b of the driving clutch contacts a projection 19a of the driven clutch gear which is connected with the shutter charging mechanism. The number of rotations of the spool 14 is predetermined by suitable configuration of the screw thread 16a. A fully exposed film is wound back into its cartridge and the back cover opened. This frees the controlling member 22 to move out of contact with the screw thread 16a, and the driving clutch 16 then returns to the position shown under spring action. In another embodiment Figs 4-6 (not shown), the controlling member (33) is separated from the back cover (24), closure of the camera back rotating an interlocking lever (35) so as to allow the spring biased clutch member to descend into contact with the member (33), the lever (35) supporting the clutch member (16) out of contact therewith when the back is open. In a further embodiment Figs. 7-13, (not shown) the clutch consists of a first member (116) rigidly secured to the shaft (12) which, after about one turn of the shaft, contacts (via projections 116a, 119a) an intermediate ring (119) which is then rotated with the member (116). The lower portion of projection (1194 then engages a part (117b) of a driving clutch piece (117) which in turn engages with a gear (121) which is part of the shutter charging mechanism. There may be more than one intermediate ring.

Abstract: 277,095. Robinson, P. G., Sargent, T., French, G. W., and Strachan & Henshaw, Ltd. June 8, 1926. Delivery apparatus.-Apparatus for delivering articles such as paper bags, and adapted to impart to them a curvature or deformation the axis or line of which is parallel to the direction of movement, delivers the bags to a device adapted to guide or centre them so as to maintain their deformation and to deflect them downwardly. Paper bags &c. are delivered from a drying cylinder 1 between bands 1<a>, 1<b> which may extend from the delivery roll 2 of the making-machine. The bands 1<b> upon which the margins of the bag rest pass beneath pulleys 3<a> and over pulleys 4<a> mounted on a pivoted adjustable frame 3 and the bags are deformed or curved by a central band 6 which passes beneath one of the pulleys 3a and beneath a pulley 6<a> disposed in the frame 3 and at a lower level than the pulleys 4<a>, the band 6 thus lying in a plane which intersects or diverges from the plane of the bands 1<b>. An adjustable finger 3<c> depresses the rear part of the bags as they pass from the frame 3 to prevent any bag from hindering the next following one. Suction means or an air blast may be used instead of the finger 3a. The bags fall on to a, tranversely moving conveyer 7 disposed at the same inclination as the bands 1<b> on the frame 3. An adjustable conical or domeshaped member 11 rotated about an axis parallel to the plane of the conveyer and in the same sense as the movement of the conveyer 7 directs the bags on to the conveyer and imparts a transverse movement to them, a flange 11<d> at its base serving as a stop to position them correctly on the conveyer. The bags thus laid in a row on the conveyer are treated so that the movement of certain of the bags is arrested to cause following bags to pile themselves one upon another. The bags may be arrested by a pivoted arm which is removed from their path at intervals by a cam device or they may be deposited on a transversely disposed intermittently moving conveyer. As shown in Fig. 3, the conveyer 7 delivers the bags on to a table 13 adapted to be reciprocated by a cam 13<c> through a link 13<c>. The table is formed with a portion 13<a> which is at a lower level than the table 13 itself. When the table is moved to the left, a fixed stop 14 sweeps the pile of bags into the lower part, 13<a> whence the pile may be removed. Specification 277,058, [Class 100 (ii), Printing processes &c.] is referred to.
