Title: Improvements in and relating to the Manufacture of Fibrous Pulp suitable for Paper-Making from Saw-dust and Wood-Waste.
Inventor: WESSEM JAN CAREL VAN
IPC: D21B1/06
Filed: 1918-06-27
Abstract: 117,086. Wessem, J. C. van. Dec. 23, 1915, [Convention date]. Pulp, preparation of.-Long fibre half stuff light in colour is obtained from saw-dust and other wood waste by subjecting the material to grinding in the presence of not more than 60 per cent of its weight of water, the heat developed by the grinding being used to vaporize part of the water so that the final product contains not more than 30 per cent of moisture. The material from a cyclone 1 is delivered through a crusher 2 to a sorting machine 3 where it is mixed with material from a cyclone 4. From the sorter, the large pieces are conducted back to the crusher, the remainder passing through a weighing-apparatus 5 to a drum 7 in which it is mixed with the correct quantity of water passed through a meter 6 from a tank 19. A screw conveyer 8 conducts the mixture to a supply tank 9 and a conveyer 10 from this tank to a grinding-maehine 11 in which the long fibre half stuff is produced. The temperature in the grinding-machine must not rise above 90‹ C. An exhauster 12 forces the material to a cooling-cyclone 13 from which it passes to a sorting-machine 14. Big pieces are returned to the crusher 2, and the remainder passes to an automatic weighing-machine and from there to the hopper 16 of an hydraulic press 17.

Title: Improvements relating to the degassing and devolatilising of low vapour pressure liquids
Inventor: BURROWS GODFREY
IPC: B01D3/10
Filed: 1950-05-01
Abstract: Liquids of low vapour pressure are degassed prior to high-vacuum distillation by heating the liquid in a container having a <PICT:0695560/III/1> vapour-exit attached to the lower end of a vertical tube which is open at the upper end, both the container and the vertical tube being wholly disposed inside an evacuated vessel; the tube is cooled over at least a part of its length, thus acting as a reflux condenser, and the gases escape from the upper end of the tube into the enclosing vessel from which they are continuously withdrawn by the evacuating means.  The necessity for apparatus with hot vacuum seals is thereby obviated.  In the Figure, the liquid to be degassed is charged into container C; and the vertical tube D is then attached to it by means of joint C1.  The upper end of tube D is cooled by means of a cooling liquid flowing through pipe E.  The container C and tube D are suspended inside cylindrical vessel A by passing the ends of pipe E through ring E1, which is then supported on a flange at the top of vessel A. The lower part of vessel A contains a grease A1 of very low vapour pressure, which is heated and maintained in the liquid condition by electric heater B, the temperature being measured by thermo-couple T.  The container C is almost wholly immersed in the heating medium A1.  Vessel A is evacuated by diffusion pump G and by a backing pump (not shown); a cold trap F being provided between the diffusion pump and the vessel A.  The occluded gas and the lightest volatile components of the liquid are driven out of the liquid, and find their way into vessel A through the upper end of tube D.  These lightest volatile components are condensed in trap F; while the gas is sucked away by the pumps. The less volatile components of the liquid, which it is desired to separate by subsequent high-vacuum distillation, condense on the cooler portions of tube D, and flow back to the container C.  The precise degree of separation of the volatile components is determined both by the temperature to which the liquid is heated and the extent to which the tube D is cooled.

Abstract: 1,095,422. Controlling vehicles. COAL INDUSTRY (PATENTS) Ltd. March 9, 1965 [March 13, 1964; Dec. 4, 1964], No. 10748/64 and 49452/64. Heading B7H. [Also in Division F2]. In a vehicle which is steered by differential control of two hydraulic pumps feeding respective hydraulic motors of drive means on opposite sides of the vehicle, a manually operable universally angularly movable control column 1 is connected to the two pumps by linkage through which angular displacement of the control column from a neutral position in a direction 'FR', longitudinally of the vehicle simultaneously changes the outputs of the pumps equally in the same sense and by which angular displacement of the column sideways or transversely of the vehicle changes the outputs of the two pumps in opposite senses. In Fig. 1, pivoting of the column 1 in the plane F-R about a pivot pin 2 slides a slider 9 along a slideway 9A and through links 15, 16 operates valves A, B together to control the forward and reverse motion of the vehicle. Pivoting of the column in a transverse plane rotates a shaft 5 about its axis and, through an arm 6 on the shaft 5 pivots the slideway 9A about a pin 13 to give different valve movements and hence differential speeds of the motors for steering. In an alternative (Fig. 5) movement of a column 101 about a ball joint 102 in planes perpendicular to the plane of the Figure pivots a bar 115, which is connected by flexible cables (108), (109), (Fig. 6, not shown), to the individual hydraulic circuits for the two motors, about a pin 105 to control the speed of the vehicle while movement of the column 101 in transverse planes, against the resistance of hydraulic devices 123, 124, moves the pin 105 along a shaft 116 to give differential movements of the cables (108), (109) to steer the vehicle on pivoting of the bar 115. A by-pass valve 118 for the hydraulic transmission circuits is operative in the neutral position of the column 101 when a spring-loaded sleeve 120 is pressed into a conical recess in the housing 119 of the ball joint 102. The column 101 must be lifted to cut out the by-pass valve before being moved from the neutral position.

Title: Improvements in gas meters
IPC: G01F3/22
Filed: 1923-04-20
Abstract: 218,769. Alexander, W., and Pinchbeck, Ltd. April 20, 1923. Gas-meters. - A gas-meter has three measuring compartments formed by the diaphragms and the space between the casing and the diaphragms, the gas supply to the different compartments being controlled by a pair of valves. The meter shown comprises two diaphragms 4, 5 arranged back to back and attached to a valve plate 3 and a plate 6 carrying the flag rods 7. The rods 7 are connected by links 8 to the usual crank 9 on a spindle operating through worm gearing 10, 11 the counting mechanism 12. The valve plate 3 is formed with ports 18, 19 leading to the diaphragms 4, 5 respectively, ports 20, 21 leading to the casing 1, and ports 28, 29 exhausting to the gas-outlet pipe 16. The gas-inlet pipe 15 is connected to a casing 2 enclosing the valve mechanism which consists of two slide valves 22, 23 bridging the exhaust ports 28, 29 and connected by links 24 to a pin 25 on an operating rod 26. The rod 26 is pivoted at one end to a crank 9<1> and is slidably mounted at the other in a guide 27. The pin 25 consequently moves in an oval path which gives the necessary lag in the movement of the slide valves to ensure that when the port in one valve is open to admit gas to the casing the port communicating with the casing in the other valve is closed to exhaust. In order that the flatness of the oval path may be varied the pin 25 may be adjustable on the rod 26 or the portion of the rod 26 sliding through the guide 27 may be curved or, as shown in Fig. 15, the pin may be mounted on an arm 30 which at one end is pivoted to the bar 26 and at the other end is forked to engage an eccentric 32 on the crank pin 9<1>. The various parts, with the exception of the counting mechanism 12, may be inserted in or withdrawn from the casing 1 as a whole after removal of the lid 17.

Title: Improvements in electrostatic microphones and loud-speakers
IPC: H04R19/00
Filed: 1946-04-09
Abstract: 610,297. Electrostatic instruments. ETABLISSEMENTS S.E.M. April 9, 1946, No. 10848. Convention date, Jan. 22. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 17, 1946.] Drawings to Specification. [Class 40 (iv)] A condenser microphone or loudspeaker comprises two rigid plates preferably gridded, with a permanently charged dielectric membrane stretched between them. In the case of a microphone, vibrations of the diaphragm cause varying potential differences between the plates and in the case of the loudspeaker, varying potential differences across the plates cause the diaphragm to vibrate. The diaphragm is composed of one of the following substances which retain their charges for long periods, e.g. polythene, cellulose nitrate, cellulose acetate, cellulose acetobutyrate, dichloroethylene polysulphide, benzylcellulose or polymers of vinyl acetate. The diaphragm may be charged to a potential of 10,000 to 15,000 volts either by contact with a source of high potential or by friction.

Title: Improvements in cathode ray tubes
Inventor: ALLISON CHARLES THOMAS
IPC: H01J29/86
Filed: 1953-04-21
Abstract: 762,088. Cathode-ray tubes. MULLARD RADIO VALVE CO., Ltd. April 20, 1954 [April 21,1953], No. 10930/53. Class 39(1) In a cathode-ray tube designed for use with deflecting coils, the neck has a precision bore and the gun has locating means engaging the precision bore and two spaced annular projections formed from the material of the tube neck and extending outwardly from the neck serve to locate the deflecting coils and external magnetic focussing means. In manufacture precision bore tubing 19, Fig. 2, is slipped on to headstock mandrel 2 and tailstock mandrel 11 is inserted until a plug and pin thereon engage a recess and socket. A tool is inserted in slot 17 so as to rotate extension 3 relatively to mandrel 2 and to expand rubber ring 5 radially to grip tubing 19 (since the pin and socket are eccentric and 2, 3 have a threaded connection). Then clamping member 14 is rotated on tailstock mandrel 11 to make rubber ring 16 expand radially and grip tubing 19 . A further rotatable member (not shown) fixed to the tailstock of the lathe engages in an axial tapered hole in mandrel 11. To form an annular projection the left hand set of burners 20 are lit and soften the rotating glass tube locally so that by admitting compressed air along the axis the softened glass is forced against roller 21. The other projection is formed similarly using the right hand set of burners. The centrifugal force may, however, be sufficient to expand the glass without using compressed air. The correct setting of roller 21 can be achieved by using a steel tube, in place of glass tube 19, having an equal inner diameter and an outer diameter equal to that of the desired annular projections. The precision bore tubing is preferably made originally by the process described in Specification 640,878 [Group XXIII], in which a graphite mandrel is moved through the tubing with simultaneous passage of a zone of heating along the tubing. The gun comprises a cathode (not shown), modulator 24, Fig. 5 and anode 23 carried by three insulating rods 25 and clamping bands 26, and is supported and spaced from the tube envelope by two collars 27 each having three protuberances 28. The completed tube is mounted on a chassis, Fig. 7. The annular projections fit in sleeve 31 which carries deflecting coils and focussing coil or magnet 36, 37 and which is pivotally mounted in forked bracket 32 carried by rotatable rod 33, so that the tube face can be accurately registered with a screening mask or scale. There may be more than one roller 21 or other gauges may be used.

Abstract: 1378745 Buckles K D MACDONALD 9 Dec 1971 [18 Dec 1970 23 April 1971 2 June 1971] 60290/70 11036/71 and 18657/71 Addition to 1209768 Heading E2A A seat-belt buckle includes a normallyclosed switch 14 which energises a solenoid 10 blocking the full opening of the throttle until the buckle is fastened, but this may be over-ridden by a seat-occupancy switch 12 in the back-rest of the seat, this enabling the driver to obtain full power by leaning forward off the switch. The pedal 15 normally operates the throttle-rod 18 through a stiff spring 20 but when the armature 23 of the solenoid projects on energisation, it blocks the movement of rod 18 and pedal pressure simply compresses the spring. Passenger switches 14' and 12' may also be used. Position sensitive mercury switches in the buckle may be used to ensure that the belt is on the user and not merely lying on the floor (Figs. 6 and 7, not shown).

Title: Improvements in or relating to the manufacture of guide vanes for axial-flow turbines and compressors
IPC: F01D5/14
Filed: 1946-04-10
Abstract: 627,295. Milling turbine blades. LOMBARD, A. A., and DAZELEY, W. E. April 10, 1946, No. 11069. [Classes 83 (ii) and 83 (iii)] Guide vanes for axialflow turbines or com. pressors are manufactured by a repetition method comprising the steps of first shaping the vane proper to its final configuration, support. ing the vane in a jig which engages it at points or lines defining, in the final assembly of vanes, the theoretical throat area measured between adjacent vanes and machining the locating means on the vane while it is so supported. The points or lines which' define the throat area are the trailing edge 14, Fig. 3, and the nearest point 15 to the trailing edge on the convex side of the adjacent vane. The jig comprises a block 17, Fig. 4, with an opening 18 to accommodate the vane, the trailing edge of which is received in a groove 19 while a pin 20 forms an abutment against which the convex face of the blade is held by a screw 21. The axes of the pin 20 and the screw 21 are relatively displaced in a manner which causes the trailing edge to bear against one side of the groove 19 when the screw is tightened. A pair of jaws 24 adjusted by nuts 25 clamp the vane in position. Lengthwise location of the vane is effected by two adjustable stops 23 engaging the inner faces of the tablets 11 and 12, Fig. 2. The edges 11a and 11b are parallel to one another and to the edges 12a and 12b so that when a vane is mounted in the jig the surfaces 26 and 27 of the latter are parallel with the upper and lower edges of the tablets while the side edges of tablet 11 are parallel with the jig surfaces 28. A base 29 mounted on the table of a horizontal milling-machine carries the jig which is traversed past rotary cutters to machine the edges 11a and 12a and, by inversion of the jig, the edges 11b and 12b. The side edges of tablet 11 are machined by mounting the jig with its side surfaces alternately accommodated in a base of configuration different from that shown. A similarly-constructed jig with its side surfaces 28 parallel with the side edges of the tablet 12 is employed to machine these edges. Two jigs may simultaneously be accommodated in the base. Specification 611,326, [Group XXVI], is referred to.
