Abstract: 142,762. Hunter, W. Dec. 22, 1919. Cam-actuated pumps; valve-gear; valves, arrangement of.-Relates to single-acting plunger pumps of the kind in which an axially moving ported sleeve serves as a valve, and consists in providing means by which the volume of liquid in the pump is not affected by the movements of the valvesleeve, such means, preferably, taking the form of a dummy piston on which the open end of the valve-sleeve slides. As shown in Fig. 1, the ported sleeve 6 moves over the dummy piston 10 and has ports 8, 9 which can register with the inlet port 2 and outlet port 3, respectively. The sleeve 6 and plunger 13 are reciprocated by rollers in cam-grooves 14, 16 on opposite sides of the disk 18 which is carried on a square shaft 19, rotated by power or by a hand-wheel 22 provided with ratchet teeth engaged by a pawl 24 to prevent rotation in the wrong direction. The cam-grooves have each two opposite circular portions to provide the necessary dwells, one cam being 90 degrees in advance of the other. A pin 25 in the sleeve moves in a hole in the barrel 1 to prevent relative rotation of the sleeve and barrel. The meeting faces of the parts 11 and 12 may be left rough to allow air to pass into and out of the space below the sleeve-valve, or a radial groove may be cut in one or other for this purpose.

Title: Process for building up the size of particles in aqueous silica sols and stable sols and pulverulent silica products produced thereby and therefrom
IPC: C01B33/151
Filed: 1949-12-15
Abstract: Aqueous silica sols, which contain dispersed silica in the form of comparatively large particles and which are amenable to concentration to 35 per cent silica content without gelling, are prepared by heating an aqueous silica sol containing silica particles of less than 10 millimicrons diameter to above 60 DEG C, adding more of the sol and continuing the heating and addition until at least five times as much silica has been added as was originally present or until the silica particles have grown to at least 15 millimicrons diameter.  By continuing the heating and addition, silica in the form of substantially spherical high-molecular weight particles of 15-130 millicrons diameter may be precipitated and precipitation may be accelerated by the addition of salts of monovalent or polyvalent metals, e.g. sodium chloride or hydroxide and the chlorides, sulphates, nitrates, sulphamates and carbonates of calcium, magnesium and zinc.  During the heating and addition the pH of the sol is preferably maintained between 9-11.  Heating is accomplished with or without evaporation of water and when the former is the case evaporation is preferably effected at such a rate in relation to the addition p  of fresh sol as to maintain the volume of the combined sol substantially constant.  Various preferred limits for the silica-alkali rates, relative viscosity, particle molecular weight and absolute turbidity of the sols during manufacture are given. Concentration of the sol may be effected by evaporation or electro-decantation.  The sols may be employed as a filler for rubber and for coating paper.  The initial sol may be prepared by ion-exchange treatment of alkali silicate solutions; by adding acid to sodium silicate solution and dialyzing out the sodium salt; by the hydrolysis of methyl silicate, silicon tetrachloride or silicon sulphide; by electro-osmosis of sodium silicate solution; or by electrolysis of sodium silicate solution with a mercury cathode. Specification 645,703 is referred to.

Title: Method of and apparatus for producing iron and steel
IPC: C21B13/00
Filed: 1959-09-21
Abstract: 935,070. Reducing iron ores. THEODOR WUPPERMANN G.m.b.H. Sept. 21, 1959 [Sept. 20, 1958], No. 32236/59. Class 72. A method of reducing iron ores comprises introducing a hot annular stream of gas into a container adjacent the bottom to provide an ascending flow adjacent the wall and a descending flow near the centre, there being a reversing point between the ascending and descending flows, introducing finely - divided raw materials and reagents near the reversing point, the size of the particles, the amounts of the materials and the gas speed being so related that there is relative movement between the particles and the gas, and collecting the molten metal produced at the bottom of the container. As shown, hot gas is introduced into a conical container 1 through blowers 5 to form two spiral rising currents 13, 14 which combine and are reversed in direction of flow by a head 2 of the container and form downwardly-moving spirals 15, 20. A distributer 11, which may be rotatable, supplies raw materials and reagents, of size 50 microns, to the gas stream and these particles form a whirl 16 which also rotates round the axis of the container. As the concentration of particles in the whirl increases the largest and finest are removed by the flows 15, 20, the remainder moving downwardly against the flow 13 and are removed through channels 18, the particles in the gas stream 15 being removed and collected at 10. The gas flow may carry some reagents in finely divided form, and additional heat may be supplied by heating the walls of the vessel.

Title: Electric safety lamp
IPC: F21V25/02
Filed: 1949-12-15
Abstract: 661,748. Mechanical switches without quick action; switches held set and freed mechanically. TRIGGS, W. W. (Edison, Inc., T. A.). Dec. 15, 1949. No. 32245/49. Class 38 (v). [Also in Groups XI and XXXVI] In a safety lamp for use in mines the electric light bulb is mounted on a movable arm of a normally closed switch in the bulb circuit, the switch tending to be operated to open position by a spring member bearing against the base of the bulb, the spring member however being overpowered by a restraining member pressing against the glass of the bulb ; thus on breakage of the bulb the restraining member can no longer act thereon and the spring member opens the switch. A switch lever 17 pivoted to a U-shaped frame 16 within the lamp casing comprises two legs which embrace a lamp holder 19 and then join together to form a single switch blade 17c for engaging a, contact 24 formed by two arms which are in lateral contact at their ends only and are otherwise spaced so that the blade 17c can move between them. The double filament bulb 20 has two end contacts abutting two spring arms 28, 29 urging the bulb and the switch arm 17 outwardly to break the contact 24 ; but movement of the bulb is normally prevented by an arm 50 pressed by a spring 51 against the bulb glass. If the bulb is cracked the arm 50 crushes the glass and moves up against a stop to break the filaments and to allow the switch arm to be moved from the contact 24 by the spring arms 28, 29. The latter are secured in insulating manner to the frame 16 and extend to form the stationary contacts of a rotary switch 32 (Fig. 5) comprising a rotary metal cylinder 33 having insulated inserts 36, 37, extending over 270 degrees and displaced 180 degrees and an operating knob located outside the lamp casing. The cylinder is connected to the electric supply through a spring arm 42 which is secured to the casing and is ridged to co-operate with four equally spaced peripheral notches 44 on the cylinder to define four positions of the switch. In two of these positions, spaced 180 degrees apart, one or other of the filaments is energised and in the other two positions both filaments are de-energised.

Abstract: 873,050. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and STEELS ENGINEERING PRODUCTS Ltd. Oct. 2, 1959 [Oct. 15, 1958], No. 32938/58. Class 38 (3). A hoist motor M, having a series field winding FS and an aiding separately-excited field winding FSH, is adapted to be supplied from a generator G which is driven by a variable-speed prime mover. During lowering operation, the motor acts as a generator and its armature is shunted by resistor RL, a rectifier RE being connected across the series winding FS to bypass reverse current. This prevents the winding FS from opposing the winding FSH if the generator voltage exceeds the motor voltage. For hoisting operation, the connections of the armature and series field windings of the motor are changed, the flux directions in the windings FS, FSH, remaining the same as for lowering operation. Speed control of the motor is effected by throttle control of the prime mover during both hoisting and lowering operations. During lowering, the motor is readily transferred between dynamic braking and motoring operation. In a modification, the same field winding may be connected in series with the armature, or to an external source, for hoisting and lowering operation, respectively, Figs. 1a, 1b (not shown).
