Title: Improvements relating to the preparation of titanium oxide
IPC: C09C1/36
Filed: 1931-04-17
Abstract: Anhydrous titanium dioxide is ground wet or dry and brought into suspension by means of an inorganic or organic dispersing agent, whereafter the fine particles are separated from the coarser ones, as by decantation or filtration, and recovered by coagulation.  The coarser particles are mixed with a fresh charge for further treatment.  Sodium or potassium hydroxide, ammonia, or alkali silicates are the preferred dispersing agents, and they may be present during grinding and in such quantity that the slurry has a pH value of 9 to 12.  Coagulation of the fine particles may be effected by neutralization, for instance with sulphuric acid, or by barium sulphate which remains in the product, or by magnesium sulphate. Additional dispersing agents which may be used include alkali carbonates, tri-alkali phosphates, sodium stearate, and certain "wetting" agents such as phenol and sodium sulphoricinate.  Titanium oxide calcined with the addition of alkali metal sulphate may be treated by the process, or the product thereof be subjected to dry grinding in the manner described in Specification 354,799. Specifications 225,593, 252,262, and 275,672, [all in Class 1 (iii), Oxides &c., Metallic], also are referred to.

Title: Improvements in or relating to devices for varying the fuel quantity to be injected and for adjusting the injection timing of injection internal combustion engines
IPC: F02D1/12
Filed: 1958-04-11
Abstract: 839,796. Fluid-pressure servomotor control systems. BOSCH G.m.b.H., R. April 11, 1958 [April 13, 1957], No. 11497/58. Addition to 818,699. Class 135. The fuel injection quantity and timing in a fuel injection internal combustion engine are controlled by servo-pistons 68, 10, respectively, under the control of a centrifugal governor 8 which comprises balls 37 acting between a dished member 114 fixed axially on a shaft 111 and a chain-wheel 112, by which the governor is driven, axially movable on the shaft. The member 114 is loaded by an adjustable spring 42 so that the force applied by the shaft 111 to a valve member 96 is the difference between the spring force and the governor force. The governor force is also effective on a valve member 97 constituted by an extension of the chain-wheel 112. The valve members 96, 97, outlets from conduits 60, 7, respectively, fed by pumps 26, 2, thereby controlling the servopistons 68, 10 which are connected to the conduits 60, 7. The outlets from the valve members 96, 97 and the low-pressure sides of the servo-pistons 10, 68 are connected to the fuel tank 3 through a valve 103 which maintains the pressure slightly above atmospheric. Restrictions 77, 80 in the connections to the servo-piston 10 prevent displacement of the latter by sudden forces produced by rotary oscillations of the pump shaft 15. The servopiston 68 is also subject, in the lower part of the speed range of the engine, to control by a valve member 90 which controls a further outlet from the conduit 60 and is subject to the pressures in the conduits 7, 10 acting in opposition to a spring 92. To cause the injection pump 1 to give a high delivery for starting the engine a spring-loaded piston valve 83 is inserted in the conduit 60 between the servo-piston 68 and the valve member 96. This valve 83 is normally held by pressure in the conduit 7 in the position shown in which it does not interrupt the conduit 60 but when the engine is being started lack of pressure in the conduit 7 causes the valve 83 to interrupt the conduit 60 whereby the servo-piston 68, being subject to the full delivery pressure of the pump 26, overcomes a spring-loaded stop 70.

Filed: 1946-04-15
Abstract: 625,023. Impedance measurements. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. April 15, 1946, No. 11543. [Class 37] A Wheatstone bridge measuring or computing device comprises a plurality of bridge networks each of which comprises an arm adapted to be set to represent an independent variable, arms adapted to be set to represent other independent variables or parameters, and a balance arm adapted to be adjusted to obtain balance and which will represent a dependent variable, the balance arm of each bridge being coupled to the independent variable representing arm of the next bridge, if any, so that these arms vary together in accordance with a predetermined relationship of adjustment, the adjustment of the balance arm of the last bridge determining the value of the dependent variable finally to be ascertained. Fig. 1 shows a D.C. arrangement employing two bridges, of which the first has four arms P1, Q1, R1, S1, a galvanometer G1 and a voltage source V being connected across the diagonals. The arm R1 is given a value representing an independent variable and arms P1, Q1 are set to given values representing other independent variables or parameters. The bridge is then balanced by adjusting the arm S1 by means of tappings for coarse adjustment and a slider RS for fine adjustment. The second bridge has arms R2, P2, Q2, S2 and a galvanometer G2. The coarse and fine adjustments for the arm S1 are mechanically coupled with similar adjustments for the arm R2, the relationship between mechanical movement and change in resistance of the coupled arms S1, R2 being chosen to introduce a desired function, such as a logarithmic function. This may be effected by adopting different laws of variation of the arms S1, R2 or by introducing a mechanical drive B giving the desired relationship. As many bridges as may be required may be similarly coupled, each bridge introducing new parameters and independent variables and each inter - bridge coupling introducing a new functional relationship. The arm R1 may be a specimen of wool material of which it is de. sired to measure the moisture. The arms P1, Q1, P2, Q2 are set in accordance with an equation representing the law representing the variation of resistance with moisture, temperature, &c. and the first bridge is balanced so that the arm R2 of the second bridge is automatically set. The second bridge is then balanced by adjusting the arm S2, which may be calibrated in moisture content. One or both bridges may be self-balancing. Fig. 2 shows a modification in which the first bridge is energized by an oscillator V1 and the second bridge by a D.C. source V11. Each bridge has its own meter M, M1, a differential voltmeter employing two diodes D1, D2, being employed in conjunction with the meter M. Specification 625,024 is referred to.

Abstract: 101,858. Holmes, W., Holmes, E. T. D., and Holmes, H. S. Sept. 1, 1916. Bell and gong signals.-A pneumatically-operated step-by-step signalling-device, particularly for use in mines, comprises a spring-returned plunger b by which impulses are sent through a connecting-tube d to a receiving-cylinder e, in which works a piston f connected to one end of a lever w. The lever m carries a pawl n adapted to engage pins o of a lantern-wheel p rotating it, against the action of a weight, one step for each impulse received. Backward movement of the wheel p is prevented by a spring detent v engaging a ratchet-wheel t. A disk bearing signal numerals and words rotates with the wheel p so that the numerals and words are successively displayed through apertures s in a plate u mounted in front of the disk. The detent v may be disengaged, so as to cancel a signal, by a lever w operated by pulling a wire x. When the wire x is pulled, the end of a lever z moves under the lever w, thus holding the detent out of action until the ratchet t returns to the zero position, whereupon a lug t<1> strikes against the lever z, releasing the lever w and detent v. A second piston working in a cylinder i is connected to, and moves with, the piston f to displace air, whereby a plunger k is driven out to strike a gong l. The pneumatic action may be adjusted by sleeves d<1>, j<1> which regulate apertures through which air may be allowed to escape.
