Abstract: 720,681. Single-rail vehicles. ROAD MACHINES (DRAYTON), Ltd., and ROBB, W. M. Feb. 7, 1953, No. 3504/53. Class 103 (4). A vehicle for traverse on a monorail system incorporates a pair of bogie units having track wheels 8 for engagement with the rail 9, each unit being rotatably mounted so that as the track wheels of the units are turned out of alignment with the longitudinal axis of the vehicle when rounding a curve, a partial tilting of the vehicle about its longitudinal axis takes place automatically in an inward direction relatively to the curve. As shown, the body 5 of the vehicle is mounted on a frame 6 connected at each end to a frame 7 in which is rotatably mounted a bogie unit. The unit has a circular channel-section frame 10, serving as a track for rollers, the diameter of one pair 12 being almost the same as the width of the channel, while the other pair of rollers 11 has a smaller diameter. The frame 10 at the bottom wall has two arcuate wedge blocks 13, the arrangement being such that as the wheel 8 moves out of alignment with the longitudinal axis of the vehicle, one of the rollers 11 moves up a wedge block while the other roller moves down a wedge block, to effect tilting of the vehicle. The bogie units are provided with guide rollers 19 engaging the top of the rail 9, with guide rollers 17 resiliently pressed against the bottom of the rail 9 by means of adjustable rubber compression blocks. Specifications 583,760 and 720,780, [Group XXX], are referred to.

Abstract: 538,889. Valves. JACOBSEN, O. A. E. Feb. 27, 1940, No. 3626. Convention date, March 14, 1939. [Class 135] A flushing valve of the kind in which a flexible diaphragm 7 which controls the flow from a pressure inlet pipe 2 to the outlet pipe 3 is normally pressed on its seat 6 by the action of fluid pressure in a chamber 14 acting at a pressure equal to the inlet pressure over a larger area than the inlet pressure, and is moved from its seat 6 by releasing the pressure in the chamber 8 by means of a release valve which discharges into a pilot port 15, is constructed so that in the inoperative position of the flushing lever 21 the outlet from the chamber 14 is normally closed by the head of a spring- pressed plunger 19, and when this is withdrawn by operation of the lever 21 a relief valve 11 closes the outlet from the chamber. A stem 16 on the valve 11 is acted upon by the head of the plunger 19 when the lever 21 is released, and the flushing then commences and continues until the outlet from the chamber 14 is again closed by the head of the plunger. The flushing thus continues for a period which depends upon the rate of return of the plunger 19 and this is controlled by a dashpot device in the form of an adjustable grub screw 32 which controls the rate of inflow of air into the space between the plunger 19 and the screwed end of the cylinder 20 in which it operates. The plunger is fitted with a cup-leather packing 27 which acts as a one-way pressure sealing device. The valve 11 is fitted with grooved passages 18 to facilitate the passage of fluid from chamber 14, and the diaphragm 7 is fitted with a pressure-equalizing aperture 9. The lever 21 is pivoted to lugs on the lower side of the plunger casing and is bent upwardly so as to obscure the access hole to the grub screw 32.

Abstract: 1,016,491. Automatic focussing systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 31, 1963 [Feb. 2, 1962], No. 4147/62. Heading G3R. [Also in Division H1 In an electron beam furnace, the beam is fired through a small aperture in a block 31 separating the furnace chamber from the gun assembly, and the two-parts are separately evacuated through pipes 3, 25, whereby a higher degree of vacuum may be maintained around the gun, to prevent flashover, than is desirable around the molten metal to prevent sputter if gas is evolved. The metal charge 6 is held on a water cooled pan 5 supported by a hollow spindle 7 extending through a gas-tight seal 9 to move the pan to dump the molten metal through a removal duct 13. The beam is focussed at the aperture by an annular magnetic disc 35 and coil 37, waisting of the beam at 33 being assisted by making part of the chamber 23 adjacent the anode 27 of magnetic material. The Specification states that to prevent beam spread a ribbon beam is preferred. Automatic Focus Control Theory of control. The state of focus is monitored by the beam current intercepted by the block 31, which will be at a minimum for correct focus Fig. 2 (not shown). A small A.C. component is superimposed on the energizing supply, as by using an unsmoothed rectified source with a 100c/s ripple, or by supplying a separate coil 37A from 100c/s source. The Specification explains with reference to Fig. 4 (not shown) that the phasesense of the 100c/s component of the intercepted current will change from out-of-phase with the applied reference at a point A just below optimum focussing current to in phase at point C just above optimum. Control system Fig. 3 (not shown). The A.C. component of the current intercepted by block 31 is developed across a 100c/s tuned rejector circuit 44 and applied to phase discriminator 47 together with 100c/s reference signal to derive a D.C. error signal varying in magnitude and polarity as the focussing current deviates above and below the optimum value. The error signal controls a saturable reactor in the rectifier supply to the focussing coil. Approximate focus is preset manually by a second control coil on the reactor. Alternative. The Specification states that this system could obviously be adapted to electrostatic focussing.

Title: Process for the desulphurisation or simultaneous desulphurisation and dephosphorisation of steel
IPC: C21C7/064
Filed: 1935-03-07
Abstract: In the process as described in the parent Specification, the constituent elements of the slag are charged and the slag is formed from these elements when in contact with the steel at the beginning of the operation.  Only part of the elements of the slag may be charged, the rest of the elements such as iron oxide being provided by the steel itself.  The constituents of the slag may be caused to melt by the heat of the metal alone by using a flux which is introduced with the other constituents or is provided by the steel itself.  When carrying out the process in a basic converter, after the first slag is removed, only a strong base, such as lime, is added, the rest of the slag being provided by the steel bath.  The second blowing, however, is carried out for a short time sufficiently long to produce a considerable quantity of iron oxide and in consequence a strongly oxidizing basic slag which effects the refining desired.

Abstract: 877,828. Dispensing measured quantities of liquids. UNITED DRUG & CHEMICAL CO. (MIDLAND) Ltd. Feb. 2, 1960 [Feb. 5, 1959], No. 4171/59. Class 106(5) [Also in Groups XXVI and XXVIII] A device for delivering measured quantities, of an aerosol composition comprises a cylindrical chamber 1 adapted to be sealed into the neck of a container and closed at its outer end by a sealing washer 13, a cup-shaped piston 6 having a rim resiliently engaging the wall of the cylinder 1 with its open end disposed towards the outer end of the cylinder, and a discharge tube 12 which is axially movable through an opening in the sealing washer so that upon inward movement against the action of a resilient biasing means 16 it engages with, and forces inwardly, the piston 6 whereby a metered quantity of aerosol is collected in the upper part of the chamber and upon return of the tube the separation of the tube from its previous sealing engagement with the piston results in the discharge of the metered aerosol. The end 11 of the tube is adapted to co-operate with a recess 9 and frusto-conical projection 10 of the piston 6. Over a part of its outer surface the discharge tube 12 is formed with a circumferential recess 15 so as to allow limited axial movement of the tube. Upon depression of the discharge tube and piston 6 in the chamber, the resiliency of the sealing rim 7 allows aerosol to pass around the piston and into the part of the chamber above it. Upon release of the tube 12, it moves under the influence of the spring 16 in an outward direction, the piston 6 also moving in the outward direction in sealing engagement with the discharge tube, until a point in the travel when the discharge tube 12 moves out of sealing engagement with the piston, allowing the metered quantity of aerosol to be vented through the discharge tube to the atmosphere. At the conclusion of the upward movement of both the discharge tube and the piston, sealing engagement is once more established between the base of the piston and the discharge tube. A spring 18 may be provided for the purpose of urging the piston 6 upwardly. The cylindrical member can be formed with one or more crifices in the side wall and a resilient valving member disposed over the orifice or orifices to form a one way valve or valves to facilitate charging with a gaseous propellant through the tube 12.
