Title: Improvements in or relating to the destructive distillation of residues from pulp manufacture
IPC: D21C11/00
Filed: 1929-10-14
Abstract: Cellulosic material from plants of annual growth, such as cornstalks, is digested with alkali and the residual liquor is dried and destructively distilled at a temperature not above 300 DEG  C., the remaining porous carbon serving as a source of active carbon.  The residual liquor is preferably acidified before evaporation to precipitate water insoluble pentosans.  The liquid is then spray dried and distilled to yield a fuel gas and organic compounds. Specification 13409/91, [Class 2, Acids and salts, Organic &c.], is referred to.ALSO:Cellulosic material from plants of annual growth, such as cornstalks, is digested at low pressure with an alkali, and the residual liquor is dried and destructively distilled at a temperature not above 300 DEG  C.  The residual liquor is acidified with sulphuric acid before evaporation usually to a hydrogen ion concentration of pH 4,4 to precipitate water insoluble pentosans, which are filtered off.  The liquid is then spray dried and the residue distilled.  The condensed vapours yield organic acids, hydrocarbons, phenolic bodies, furfural or furfuramide. The fixed gases containing carbon monoxide, methane, hydrogen and sometimes ammonia and amines serve as fuel gas.  The remaining porous carbon is used as a source of active carbon.  Specification 13409/91, [Class 2, Acids and salts, Organic &c.], is referred to.

Patent GB-439764-A (GB)
Title: Improvements in or relating to the production of concentrated lower aliphatic acids
IPC: C07C51/487
Filed: 1934-10-31
Abstract: <PICT:0439764/IV/1> <PICT:0439764/IV/2> The concentration of lower aliphatic acids such as acetic acid is effected by adding the dilute acid to a solid salt of the acid such as an alkali or alkaline earth salt so as to form an acid salt, under such conditions and in such proportions that the product remains substantially dry or powdery, the acid salt being then decomposed to liberate the concentrated acid.  The dilute acid may be supplied in liquid or vapour form, and may be added in restricted quantity whereupon evaporation of the water is effected, or it may be added gradually with simultaneous evaporation of the water.  In a batch process, dilute acetic acid is supplied from a vessel 11, Fig. 1, to sodium acetate in a reaction vessel 18 having stirring means 24, 26 and fixed rods 27 which may act as distributers for the acid.  The sodium acetate is heated to 60 DEG  C. and acid is admitted until it shows signs of dampness; the acid supply is then stopped and the temperature is raised to 90 DEG C., vapours escaping at this stage (about 6--14 per cent acid) being condensed in a condenser 34.  The reaction vessel is then brought to 140 DEG  C., the liberated acid being collected in a condenser 38. The process is preferably conducted under reduced pressure, and the acid vapours pass through a dust separator 32 before reaching the condensers.  In a continuous process, the sodium acetate passes in succession through conveyer vessels 44, 47, 59, the dilute acid being supplied from a tank 41 by a pipe 43 to the first conveyer, the volume of dilute acid supplied in any time being slightly less than the volume of sodium acetate supplied to the conveyer in the same time.  The first conveyer is at 60 DEG  C., the second at 95--100 DEG C. and the third at 150 DEG  C. Vapours from different points of the second conveyer contains 3--14 per cent of acid, the 14 per cent vapour being returned through a condenser 57 and/or line 42 to the storage tank 41.  The acid liberated in the third conveyer is drawn through outlets 61, 62, 63, 64 by a vacuum pump 69, dust collector 71 and condenser 72 to a storage tank 73.  If the acid salt entering the third conveyer still contains water, the acid vapour from the entrance end may be sent back by way of valves 65, 66 to the store tank 41. The sodium acetate is returned to the first conveyer by a conveyer 76.  The hopper 46 is provided with a valve such as a bell valve to allow a reduced pressure to be maintained.

Title: Gear-cutting method and apparatus
Inventor: MCDONNELL KEITH FREDERICK
IPC: B23F23/12
Filed: 1960-09-14
Abstract: 936,585. Gear - cutting; gear - finishing. DRUMMOND BROS. Ltd. Dec. 14, 1961 [Sept. 14, 1960], No. 31727/60. Class 83 (3). In a hobbing machine or a gear-shaping machine using a rack or pinion-cutter for finishing a series of rough-cut gears, means 23 are provided for locating a workpiece with respect to the positions of its cut teeth. The work can be held loosely by an hydraulicallyoperated centre 4 so that the teeth can be positioned, can be held firmly by increased pressure, or can be clamped fast by an hydraulically-operated centre 3. The locating means 23 comprises a gear having spaced rings of teeth. It is mounted on an arm 8 pressed forwardly by a spring 27 in a sleeve 7 which can be swung about an axis 6. The locating gear can be clamped by a block 24 attached to a fluid-pressure piston. The arm 7 is located in its operative position by a stop 35, movements being controlled by switches actuated by a rod 60 and plungers 55. In operation, the first workpiece of a series is located relatively to the cutter by bringing the cutter into mesh with the gear while the latter is free to rotate. The gear is then clamped fast and the locating gear is swung into mesh with the gear. Cutting then ensues. When cutting is complete, the cutter is withdrawn, the locating gear is clamped against rotation, the work is released for free rotation and the locating gear is swung away. Thus, when a new gear is positioned, the locating gear represents the correct relative meshing position of the cutter. If the locating gear swings into a position against the tops of the work-gear teeth the arm 60 operates a switch 63 and the arm is swung away. It is then swung back again until correct meshing occurs. The locating gear may mesh with a gear other than that to be cut and teeth may then be rough-cut or finish-cut on the same workpiece.

Title: Improvements in electric receiving or switching devices for remote control installations
IPC: H02J13/00
Filed: 1947-12-03
Abstract: 637,415. Actuation of switches. LANDIS & GYR SOC. ANON. Dec. 3, 1947, No. 31961. Convention date, Dec. 10, 1946. [Class 38 (v)] A switching device or " receiver for a remote control installation has a synchronous motor, which when started by an audiofrequency responsive relay rotates a control shaft through one complete revolution, and through gearing loads a spring which when released by the action of the relay on the receipt of a second audio-frequency impulse, actuates a selected switch unit. An audiofrequency impulse superimposed on the lines a, b momentarily energizes relay coil 2 to turn the relay armature 3, which by means of a cam 5 closes contacts 7, 8 to energize the synchronous motor 12. The motor then drives the control shaft 15 through one revolution, the contacts 7, 8 being held closed by a cam disc 28. The motor also drives a shaft 19 through gears 16, 17, 18 and loads a spring 38 frictionally held between the gear 18 and a cam unit comprising a switch-actuating cam 36 and latching cams 34, 35, which are fixed together as a unit and free to rotate as a whole on the shaft 19. The cam unit is normally held stationary by a lobe or arm of one of the cams 34 or 35 abutting one of the downwardly projecting arms 32, 33 of leaf spring control levers 30, 31. These levers are held down in the latching position by abutments 26, 27 on them engaging the peripheries of control discs 20, 21 which are adjustably secured to the shaft 15. The discs 20, 21 have notches 24, 25 into which the abutments 26, 27 can move when the arms 28, 29 extending from them are free to move. Hence the first impulse received by the relay starts the motor and then to bring about a switching operation, a further impulse must be received by the relay at a timed interval afterwards, so that it may turn a cam 6 to remove a bar 9 out of the path of the arms 28, 29 as one of the notches 24 or 25 comes over its associated abutment 26 or 27. In the Figure the switch contacts 37 are closed, so that if the relay is energized when the notch 25 is over the abutment 27, the control lever 31 moves upwards disengaging the arm 33 from the cam 35, so that the cam unit is turned by the spring until an arm or lobe of the cam 34 abuts the arm 32 and the switch 37 is now held open by a lobe of the cam 36. Further actuation of the relay when the notch 24 is over the abutment 26 enables a further movement of the cam unit to occur to open the switch. Additional control discs 20, 21, levers 30, 31, cam units 34 ... 36 and springs 38 may be provided to control selectively additional switches 37. Specifications 494,792, [Group XXXVIII], 633,195 and 637,416 are referred to.

If a truck is absent the brake rails rest on supports s lower than the top of the wheels. Two plates a are suspended on pivot pins b, c on the brake beams d, e which are mounted on rotary axles f, g on the four uprights of a brake stand, a lever frame m bearing against a rigid surface p by means of a roller n transmits the force of the weight h by pins l to the plate a. A compressed air piston q is adapted to push the lever frame so that the plates a first pivot round pins b and when the rails e press on the truck wheels round the pins c to raise the rails d. A safety latch k is removed by the movement of the frame m when the front truck is released. By shutting off the pressure means the weight descends again returning the mechanism to its initial position in which the front brake rails rest on the supports s until the second truck is released by the rails e and rolls under the rails d. An oil cylinder v damps the return movement. To allow the release of two trucks at once the apparatus is lengthened. The weight may be carried at the point l.
