Title: Improvements in apparatus for use in scalding animal offals
IPC: A22B5/12
Filed: 1928-05-16
Abstract: 317,421. Hill, F. May 16, 1928. Boiling-pans.-Apparatus for scalding animal offals, consists of a tank having a channel for the passage of the scalding liquid from the place where the offals are inserted to the place where they are removed, the flow of the liquid and also the heating thereof being caused by steam jets. The tank 6 is partitioned at 7 to form channels 9, 10 joined by a semicircular portion. The partition 7 is perforated at the charging end so that the liquid flows in a circular path, the flow being induced by steam, injected through a pipe or pipes 12. The pipe 12 is adjustably screwed into a bell 13 which is perforated at 15 to admit water from the tank, and is connected by a pipe 14, 22, to the atmosphere, air being thus admitted to the bell to prevent the steam from making excessive noise during injection. The offals are carried along by the current, or may be assisted by the operators. The partition is braced by a cross member 27, and the upper exposed edges of the apparatus are rounded off by beadings 26 to prevent damage to the hands and arms of the operators. Water is supplied in any manner to the tank, and draining is effected through the screw-plugged opening 24.
Patent GB-950570-A (GB)
Title: Improved procedure for production of itaconic acid
Inventor: NUBEL ROBERT CARL
IPC: C12P7/44
Filed: 1962-04-13
Abstract: Itaconic acid and salts thereof are prepared by submerged aerobic fermentation of a carbohydrate medium in which beet molasses are the source of 10 to 30% by weight of the carbohydrate using a mycetes organism, e.g. an itaconic producing strain of Aspergillus, e.g. of A. itaconicus or A. terreus. The itaconic acid may be partially neutralised during the fermentation. The remainder of the carbohydrate apart from the beet molasses may be sucrose, glucose, invert sugar or, preferably, cane molasses.  The beet molasses may be blended direct with the remainder of the carbohydrate in preparing the medium, but is conveniently employed as the primary carbohydrate source in the submerged aerobic growth of an inoculum of the micro-organism and this inoculum is then transferred to a cane molasses medium to initiate fermentation. The separate beet and cane molasses concentrations and the proportion of inoculum are selected to give the necessary proportion of beet molasses to provide 10 to 30% of the total carbohydrate. Specification 602,866 is referred to.

Title: Improvements in blasting cartridges
IPC: F42B3/06
Filed: 1933-05-19
Abstract: 406,523. Blasting-cartridges; tampings. SAFETY MINING CO., 307, North Michigan Avenue, Chicago, U.S.A. May 19, 1933, No. 14568. Convention date, May 19, 1932. [Class 9 (i).] A blasting-cartridge containing a charge of liquefied or compressed gas is provided with a closure which is mechanically removed or ruptured or weakened so as to yield to the gas pressure. The mechanical means may be operated from a distance. In Fig. 1, the cartridge 1 is shown closed by a disc 3 supported by a toggle 5, 6 which can be broken to the dotten position by a pull on a cable 9. In Fig. 2, the closing disc 3 is shown supported by a second disc 10, which can be broken by gas pressure admitted thereto by a valve 13 operated by a cable 15. In the form shown in Fig. 5, the operation of the cartridge 16 is brought about by a gun or power hammer 20, which may contain a spring plunger held cocked by a trigger releasable by a pull on a cable, or may contain a pneumatic plunger held cocked by a trigger released by a pressure gauge when sufficient pressure, say 150 to 175 lbs. per sq. in., is admitted behind the plunger. This hammer device is clamped in the bore-hole by a rubber sleeve or fingers 33 expanded by a screw sleeve on the hammer device. When a blow is struck by the hammer on the cartridge 16, a member 19 at the inner end is driven in and releases the gas. For example, the member 19 fits in a hole 48, Fig. 11 of the cartridge 1, and wedges a post 42 off a seat 44, thereby allowing 'the gas pressure to break a disc 38. Or this disc is omitted and the front end 43 of the post 42 acts as a valve. In the form shown in Fig. 25, the member driven into the cartridge takes the form of a punch 59 located in the end of the cartridge 1 by a pin 61 and adapted to pierce a closing disc 57. In a modification, the punch is arranged at the other end of the cartridge and is driven in directly by the blow of the hammer. The cartridge may be filled to a pressure of 5000 to 10000 lbs per sq. in. through a laterally disposed screw down valve with ports for the passage of the gas.

Title: Improvements in or relating to controlled velocity drives
IPC: H02P29/00
Filed: 1965-04-06
Abstract: 1, 082, 877. Automatic speed control. HEENAN and FROUDE Ltd. April 6, 1965 [May 6, 1964], No. 14569/65. Heading G3R. In a system for maintaining constant the speed of a shaft driven through an electromagnetic coupling, the energization of the coupling is automatically controlled by means of a switching device operated in dependence on the difference between the actual and desired speeds of the shaft and the integral of the difference. As described, the speed of a shaft driven through an eddy-current clutch is measured by a tachometer alternator the output of which is rectified and compared with an adjustable reference voltage. Any difference, representing a speed error, is applied through a transistor amplifier to control the charging rate of a capacitor associated with a trigger circuit so that the mark-space ratio of the trigger circuit output is varied. This output is applied to control a half-wave or fullwave silicon-controlled rectifier energizing the clutch winding so that the speed of the shaft is corrected. The error signal is also applied through an integrator circuit formed by an amplifier having capacitative feedback to provide an additional, integral, component of control for the trigger circuit. A second transistor amplifier, matched to the first and sharing a common heat sink, cancels the effect of temperature variations. Temperature compensation, limiting, filtering, smoothing and protection is also provided elsewhere in the circuit. Adjustable potentiometers are provided for setting maximum and minimum speed limits. A push button switch may be operated in one manner to actuate a relay energizing the clutch momentarily through the silicon-controlled rectifier to inch the shaft or may be operated in a different manner to make the relay self-holding so that the speed control system is operative until a stop button is operated.

Abstract: 678,411. Printing telegraphs. SIEMENS & HALSKE AKT.-GES. June 12, 1950 [June 13, 1949], No. 14660/50. Class 100 (iv). [Also in Group XL (b)] In a teleprinting apparatus in which the message transmitted is recorded on a web of paper, means arranged to be coupled with the drive of the apparatus effects a rapid feed of the web of paper after the termination of a message and operates a knife to sever the web of paper. The means for the rapid feed of the web and for the operation of the knife is preferably controlled by an electromagnet operated by a special signal from the transmitter. The printing web 14 is normally moved continuously by a roller 1 on the shaft of a gear wheel 2. The signal for controlling the paper-cutting energizes a magnet 4, and its armature 5 allows a cam disc 6 to move to the right under the action of a spring 7 so that gear wheels, 3, 8 driven from the wheel 2 rotate at a relatively greater speed a wheel 9 carrying a driving cylinder 10a which advances the sheet quickly. Towards the end of a revolution of the wheel 8, a cam ring 6b engages the nose 5a of the released armature 5 moving the disc 6 to the left so that the gear wheel 8 is disconnected and the tooth 6a of the disc is engaged by the end 5a of the armature. Before the disconnection of the wheel 8 a cam 13 raises a bar 12a carrying the cutting blade 12, and having an arm 19a which raises shaft 20 carrying pressure rollers 21 which co-operate with the cylinder 10a so that the rapid feed of the paper is discontinued. Attached to the bar 12a by springs 18 is a frame 16 comprising metal plates enclosing bars 17 of soft rubber gripping the sheet 14 on either side of the cutting blade 12 which is formed with one or more projecting points from which the cutting edge of the knife recedes.

Patent GB-603447-A (GB)
Title: Method and apparatus for the production of pulp from cellulosic material
IPC: D21B1/06
Filed: 1945-06-13
Abstract: <PICT:0603447/IV(a)/1> <PICT:0603447/IV(a)/2> Cellulosic fibres are separated from lignocellulosic materials by passing the materials at a controlled rate through a closed chamber containing steam at super normal temperature and pressure and an atomized solution of a soluble chemical, discharging the materials from the chamber while avoiding substantial reduction of the temperature and pressure existing therein and then mechanically defibering the so treated materials. Chemicals of an acidic or alkaline nature may be employed, such as sodium hydroxide, carbonate, sulphite, sulphide or a mixture thereof or sulphur dioxide or the bisulphites of sodium, calcium or magnesium containing excess sulphur dioxide, or ammonium hydroxide, sulphite or bisulphite or sulphuric, nitric or other mineral or organic acid. The pH value of the effluent obtained from the refined material serves to indicate the consumption of the chemical reagent employed and preferably should range between 1 and 12.  The amount and concentration of the solution of chemical reagent supplied to the reaction chamber is correlated with the time of transit of the material through the chamber and the type of lignocellulosic material employed in order to prevent degradation of the fibre structure. Referring to Fig. 1, chips or shreds of lignocellulosic material such as wood, straw, flax or bagasse are supplied from hopper 10 and compressed into plugs by screw conveyer 12.  The plugs are pressure fed through weighted valve 16 into steam chamber 17.  Steam under pressure is supplied to the chamber through pipe 18 and chemical reagent through pipe 19, the reagent being atomized by device A.  The casing of chamber 17 is of larger diameter than that of compressor 11 and the plugs of material disintegrate therein.  The material then passes into the temperature-pressure treatment zone C which is merely an extension of chamber 17 and comprises chambers 21, 28 (Fig. 2) through which the material is impelled by screw conveyers 32, 35. The material is discharged through neck 31 either to a further extension C1 of the reaction chamber or directly to compartment 39.  The speed and pitch of the screw conveyers 32 and 35 control the rate of transit of the material through the chamber.  From compartment 39 the material is progressed by screw 40 past the motor-operated duplex alternating valve assembly V which permits emission of material without undue reduction in the temperature and pressure existing in the reaction chamber.  The material then passes to cyclone 46 to which wash water and, if desired, steam is supplied before passing in suspension through refiner or grinder R, where it is disintegrated and the fibres separated from one another.  If shredded wood is to be supplied to the apparatus, the wood may be previously shredded by a device illustrated in Fig. 6 (not shown).  The fibres produced according to the process can be made into various grades of dry felt, paper or paper board.  Specification 555,966 is referred to.
Patent GB-376430-A (GB)
Title: Method of evaporating liquids
IPC: B01D1/26
Filed: 1931-05-21
Abstract: In a process for evaporating liquids of the kind in which a warm liquid is evaporated by direct contact with a cold gas-vapour mixture passed in countercurrent thereto, e.g. as described in Specification 312,089, [Class 32, Distilling &c.], the ratio of the quantity of <PICT:0376430/III/1> liquid to the quantity of gas-vapour mixture is increased or decreased according as the temperature of the gas mixture rises or falls.  The liquid may be heated between successive evaporative coolings, by indirect contact with a gas-vapour mixture which is thereby condensed and the ratio of the quantity of liquid to the quantity of indirect heating medium is decreased with falling temperature of the heating medium.  Air vapour mixture is supplied at 75 DEG  C. through a conduit 1 to a heater V1 where it is cooled to 64 DEG  in heating liquid supplied through a conduit 2, the liquid being heated from 52 DEG  to 65 DEG .  The air flows through a conduit 3 to a heater V2 where it is cooled from 64 DEG  to 40 DEG in heating liquid supplied from a conduit 4 from 30 DEG  to 52 DEG . The liquid from the heater V2 flows to an evaporator A<1> where it is evaporatively cooled from 52 DEG  to 30 DEG  by direct contact with air, supplied through a pipe 6, which is then heated from 75 DEG  to 48 DEG .  Similarly the liquid from the heater V1 is cooled in the evaporator A2 from 65 DEG  to 52 DEG  by air from the evaporator A1 admitted through a pipe 8, the air being heated from 48 DEG  to 64 DEG .  The liquids leaving the evaporators A1, A2 are returned by pumps 10, 11 to the conduits 2, 4, fresh liquid being supplied through pipes 13, 14, and concentrate drawn off through pipes 15, 16. The ratio of the quantities of liquid may be regulated by transferring liquid from one system to the other through a pipe C. The process may be divided into more than two phases and a plurality of effects may be used.

Title: Bale-handling implements
IPC: A01D90/08
Filed: 1973-04-29
Abstract: 1390142 Bale wagons SPERRY RAND CORP 29 March 1973 [4 April 1971] 15054/73- Heading B8E A bale wagon 1 has a bale pick-up unit and a bale thrower unit mounted on a carriage 25 movable vertically by rollers 29 on members 30 of a carrier frame 19 mounted by a pin 47 in a bearing 48 on the front of the wagon so as to be pivotably about a generally horizontal axis parallel to the longitudinal axis of the wagon. The pin 47 is offset from the centre of the frame 19 which thus tends to pivot anticlockwise, Fig. 3, under gravity but can be set at the desired inclination by a ram 50, Fig. 2. Unloading is effected by lowering a tailgate provided with a transverse conveyer fed by a conveyer 5 on the floor of the wagon. The wagon is drawn through a tongue 3 connected to a tractor draw-bar. The tongue 3 can be held by a pin 70 in an inclined position, Fig. 4, for bale collection or in a straight ahead position for transport, a ram 66 being provided if desired to move the tongue. The carriage 25 is resiliently supported by springs 63 from the frame 19 and is connected by a cable 55 to the tongue 3 so that as the tongue is swung to the straight ahead position the cable raises the carriage 25 clear of the ground for transportation but in the inclined position the carriage is lowered to a pick-up level. The adjustability of the inclination of the frame 19 about the pin 47 allows the position of the throw of the bales, by conveyers 37, 38 of the throw unit, to be adjusted to allow even filling of the container even when operating on uneven terrain, it also allows the pick-up unit to be correctly positioned to engage the holes.
