Title: Improvements in the treatment of cellulosic fibrous materials for the production of purified cellulose or partially-purified cellulose
IPC: A24C5/44
Filed: 1958-07-08
Abstract: In a continuous process for extracting non-cellulosic constituents from natural fibrous cellulosic material to produce purified cellulose, the cellulosic material to be purified, for example wood chips, is continuously introduced into a charging hopper 31, the lower end of which extends into digesting liquor contained in a feed tank 10 and into the mouth 16 of a pipe 15. The material, together with digesting liquor is drawn through the pipe 15 into the vacuum chamber 1 provided with a vacuum pump 7. Liquor is <PICT:0893334/IV (a)/1> withdrawn from the chamber 7 through the pipe 21 by the centrifugal pump 4 driven by the turbine 22 and electric motor 23, and discharged into the impregnating tower 22 at a rate sufficiently high to cause the concentration of cellulosic material in the liquor entering the chamber 1 to be relatively low and to maintain the height of the liquor in the chamber 1 at the level 8.  In order that the period of resilience of the material in the chamber 1 may be relatively long the material entering the chamber is discharged into a receiver 32, the upper part of which is provided with apertures so that surplus liquor can escape into the chamber 1 and flow into the pipe 21.  The fibrous material is continuously withdrawn from the bottom of the receiver 32 by a mechanically driven stirrer 36 and worm conveyed 37 at such a rate that the height of the material in the receiver remains about constant at the level 35.  The material together with digesting liquor is pumped into the impregnation tower 22 in which the liquor is maintained at the level 9, liquor being continuously withdrawn from the tower 22 at an outlet 19 through the duct 18 into the feed tank 10.  The fibrous material saturated with liquor is continuously raised by the mechanically driven worm conveyer 38 above the liquor level 9 and discharged into the pipe 6 down which the material falls into the digester 3, from which the digested fibrous material is continuously discharged through the delivery pipe 43 provided with gate valve 42.  The height of the material in the digester is maintained at the level 40 and the material is brought to the required digesting temperature by the admission of steam through the pipe 41.  Any condensate collecting above the level 9 of the digesting liquor in the tower 22 overflows through the outlet 44, pipe 45 and valve 46.  Digesting liquor may be tapped off from the digesting liquor return pipe 18 to a tank 13 through a pipe 25 branching from the pipe 18 and provided with a valve 26. Fresh digesting liquor or a mixture thereof with liquor recycled from the impregnation tower 22 is fed through the control valve 11 and pipe 12 into the feed tank 10 to maintain the height of liquor in the latter at the level 14.  Liquor from the tower 22 may be allowed to return to the tank 10 through the pipe 30 provided with a control valve 29 in order to prevent the temperature of the liquor in tank 10 from becoming too high.

Filed: 1964-05-27
Abstract: <PICT:1058116/C4-C5/1> In a method of producing a hydrogen plasma jet for cracking reactions by a swirl stabilized D.C. arc, the gas at the cathode, at the striking point of the arc, is arranged to consist of a hydrogen-hydrocarbon mixture containing 6 to 25 hydrogen atoms for each carbon atom, and the voltage/amperage ratio of the arc is between 5 and 15.  To produce the mixture at the desired point, there is introduced tangentially at 7 in the hollow cathode 3 either the mixture itself or pure hydrocarbon (e.g. gaseous or liquid methane, ethane or propane) for subsequent dilution by hydrogen from the swirl chamber 1 in the mouth of the cathode. Both electrodes are of iron and are water-cooled.  In addition to rotary motion caused by the swirl an axial movement is given to the arc, either bodily or by cyclically changing its length; it may be produced either by changing current and/or voltage, by changing volume and/or velocity of the swirl gas or by external magnetic field.  Specific examples are given, in one of which propane, introduced into the plasma jet at 8, is cracked to produce acetylene, higher acetylenes, ethylene, higher olefines, methane, higher paraffin and hydrogen in the reaction chamber 9, which has water quenching 10.

Title: Improvements in or relating to devices for automatically lubricating moving lubrication stations
IPC: B65G45/08
Filed: 1959-06-30
Abstract: 903,406. Force-feed lubricating. SCHLOSSHAUER, A. R. June 30, 1959 [Aug. 19, 1958], No. 22447/59. Class 12 (3). A device for automatically lubricating moving lubrication stations, such as the rollers 31 of a conveyer belt, has a lubricating head 3 pivotally mounted so as to be movable pivotally by said stations 31 against the action of a spring 4. The head comprises a piston 8 in a bore 9 of a cylinder 7, the piston being urged inwardly by springs 21 located between radial arms 20 of a piston headpiece 19 and pins 22 on the cylinder. The displacement of the piston 8 is by means of an auxiliary pressure medium such as compressed air controlled by a stop-valve 23 actuated by a lubricating station. The cylinder 7 is connected alternately through ports 11, 10 to a supply tube 17 for the compressed air and to an outlet 18 therefor by means of a spring-pressed piston 14 controllable by the compressed air. The supply tube 17 extends to the stop valve 23 which is connected to a supply duct 24 and when the valve is closed the tube 17 is connected to an outlet 25 of the valve 23. A member 26 of the valve 23 is actuated by a lever 28, pivotable about a spindle 27, and, as a spindle 29 having a roller 31 enters the station, the lever 28 is actuated by the roller 31 to operate the valve 23 and connect the channel 24 to the tube 17. Compressed air is accordingly supplied through the tube 17 and valve 14 to the bore 9. The piston 8 is thus moved out of the cylinder 7 against the springs 21. The piston 8 has an axial bore 32, parallel channels 35, 36 connected by a screw-threaded bore 37 to a lubricant supply channel, a transverse bore 38 connecting the channel 35 to the bore 32 and transverse bores 39, 40 connecting the channel 36 with the bores 32. A lubricating nipple, comprising a spring-urged piston 41 received by the bore 32, has a delivery bore 43 extending to a constriction 42 forming an annular chamber connected to the bore 39. The piston 41, having a follower piston 49 connected thereto by a rod 48, serves as a valve to open and close the bores 38, 40 and allow lubricant to be received between the pistons 41, 49 so that, on the piston 41 being moved further into the piston 8, the lubricant is forced through the bore 40, channel 36, bore 39, constriction 42 and the delivery bore 43 to lubricate the roller 31. The air supplied to the duct 24 passes through an air-cleaner 54, pressure regulator 55 and safety valve 56, which is closed by a lock 57 if the conveyer is reversed. Reference has been directed by the Comptroller to Specification 833,819.

Abstract: 1306108 Fluid pressure braking systems AISIN SEIKI KK 8 May 1970 [11 May 1969(2)] 22462/70 Heading F2F A vehicle having a fluid pressure operated braking system responsive to vehicle load has a pressure regulating valve 1 attached by a bracket 3 to the vehicle body and in which reciprocates a piston 19 having a land, and a valve head 16 biased out of engagement with a valve seat 18 by a spring 15 to allow fluid to pass from a master cylinder to wheel cylinders through an inlet 19 and outlet 20, the position of valve member being altered by a member 4 which may be a leaf spring or torque bar attached to an axle 8 whose position varies according to load. In the position shown where the vehicle is loaded such that member 4 is in a "neutral position" hydraulic fluid passes to the master cylinder until the pressure reaches a predetermined value at which point, piston 10 moves downwardly under pressure acting on head 16 which engages seat 18. A further increase in pressure causes the valve head to unseat and again permit communication between master and wheel cylinders. According to vehicle load, member 4 may occupy positions such as 4i or 4d to assist or oppose biasing of spring 15. Adjustment may be carried out by means of revolving bolt 13 locked by means of nuts 13a, 13b. In other embodiments spring 15 is replaced by a spring 15<SP>1</SP>, Fig. 3 (not shown), engaging the underside of member 4 and secured to bracket 3, and the member may contact piston 10 through a ball. Communication between the master cylinder and wheel cylinders may be controlled by a valve (29) engaging the upper face of piston 10 and spring biased downwardly against a seat. Member 4 may be a leaf spring between the leaves of which is positioned a rubber material to decrease vibration.
