Title: Improvements in centrifugal regulating systems

Filed: 1956-04-19
Abstract: 815,158. Speed governors. PRECISION MECANIQUE. April 19, 1956 [April 21, 1955], No. 11959156. Class 57. [Also in Group XXIX] A regulator system for an internal combustion engine fuel injection pump comprises a governor sensitive to both centrifugal and accelerative effect, the action of the governor being transmitted to the pump by means of a hydraulic servo-control system. The governor has a centrifugal mass carrier 1 rigid with the shaft 2 driven by the engine through gears 15, 16 and 17. The centrifugal masses 3 are pivotally mounted at 4 to the carrier 1 and act against an axially slidable abutment 6 through levers 7, the abutment being loaded by an adjustable spring 5. The abutment 6 is rigid with a rod 11 forming the valve element of the servomotor control valve. The masses 3 are also connected by rods 10 to a flywheel 8 rotatably mounted on the mass carrier 1 such that movement of the flywheel 8 relative to the mass carrier 1 causes the masses to move inwards or outwards according to the direction of movement. The masses 3 are therefore subject to both an accelerative and a centrifugal effect. These effects are transmitted via the abutment 6 as linear movements of the control valve element 11 which in turn adjusts the position of the servo-piston 21 connected by levers 24, 25 and 26 to the fuel pump. The driving shaft 2 also constitutes the control valve body. Motive fluid pressure is provided by a pump 18 which may alternatively be constituted by the gears 15. A pressure accumulator 20 is charged by the pump 18.

Title: Improvements in or relating to methods of, and apparatus for, controlling the solidsconcentration in a slurry produced by a wet grinding mill
IPC: B02C25/00
Filed: 1961-04-04
Abstract: 925,489. Wet grinding. INDUSTRIAL NUCLEONICS CORPORATION. April 4, 1961 [April 4, 1960], No. 12060/61. Class 59. [Also in Groups XXXV and XL (b)] The solids concentration of a slurry produced by a wet grinding mill is controlled by measuring the apparent density of the slurry and by varying the rate at which liquid is added to the mill in accordance with the density measurements. As shown, a mill 101 receives solids to be ground from a source 12<SP>1</SP> and liquid from a source 14<SP>1</SP>. A transducer 22, e.g. a radiation-absorption gauge, is located in the effluent line 20<SP>1</SP> and produces a signal in response to changes in slurry density, which signal is compared in an error sensor 24 with a reference signal, from source 26, representative of a desired density. The error signal from sensor 24 is applied to a controller 28 which actuates, over a delay unit 32, a servomotor 30 connected through gearing 34 to the liquid flow valve 18<SP>1</SP>, the arrangement being such that the flow of liquid into the mill is decreased if the slurry density detected at 22 decreases, and increased if the density increases. The delay unit 32 compensates for the time taken for material to pass through the mill and eliminates controller overshoot. In a modification (Fig. 5, not shown), the control system is applied to a closed-circuit mill having a classifier which returns over-size particles to the mill, and a further transducer is provided to measure the mass per unit time of this return flow, the rate at which new solids are added to the mill being controlled in accordance with this measurement. Specification 916,404 is referred to.

Abstract: 418,149. Smallarms. ROGERS; J., 23, Bath Street, Birmingham. April 27, 1933, No. 12241. [Class 119.] Relates to drop-down smallarms of the " hammerless " type, of the kind in which the mainspring is mounted on a carrier pivoted at the rear of the lock plate, the hammer is put into bent by the action of one arm of the mainspring when the gun is opened, and the mainspring is compressed by one end of a compressor lever pivoted intermediate its ends when the other end of the lever is operated by the closing of the gun. According to the invention, the compressor lever 2<a> has a rounded nose 16<a> which projects beyond the flat 17 through a slot in close proximity to the joint of the action. The other end of the lever bears against the front end of the mainspring carrier 18 pivoted at 18<a>. A spring 28 attached to this carrier bears on a spring 29 mounted on the action and bearing on the trigger 15<a>. The mainspring is U-shaped, limbs 21, 22 having lugs 23, 24 in a slot 25 of the carrier, and the limb 21 a nose 26 in engagement with a slot 27 in the hammer 12<a>. When the gun is opened, the carrier 18 is rocked clockwise by the spring 28, the bearing point of which on the spring 29 is behind the pivot 18<a> of the carrier ; and at the same time the nose 26 of the mainspring cocks the hammer back into bent with the trigger. When the gun is closed, the nose 16a is forced back into the action and the carrier 18 thereby rocked clockwise and the mainspring compressed.

Class 108(2) In an anti-rolling system of an automobile vehicle there is associated with each wheel R1 or R2 an individual purely hydraulic suspension cylinder C1 or C2 and an individual oleo-pneumatic accumulator A1 or A2, means for dividing each accumulator into three chambers, of which one (El or E2) is filled with compressed air while the other two (F1, G1 or F2, G2) are filled with liquid and are hydraulically connected, one to the suspension cyunder corresponding to the said accumulator, and the other to the suspension cylinder associated with the other wheel of the same pair of wheels, either front or rear. Each accumulator A1 or A2 comprises an annular piston p1 or p2 carrying a bell c1 or c2 and slidable on a cylindrical member d1 or d2 mounted on one end of the accumulator. A formula is given for determining the areas of the annular pistons p1 or p2 and of the cylindrical members d1 or d2 to produce a given degree of rolling for a given lateral acceleration.

Addition to 407,830. [Class 41.] A porous layer of metallic lustre, serving as carrier for the light-sensitive substance, is produced by subjecting a plate, foil &c. of aluminium or aluminium alloy to the action of an electric current in two different baths successively, e.g. baths of chromic, oxalic, sulphuric or malonic acids. Preferably, the articles are connected, as anodes, to a source of direct current, but alternating current, pulsating direct current, or direct superimposed or alternating current may be employed ; a direct current may be employed in the first and alternating current in the second bath. In an example, a polished aluminium sheet, as anode, is subjected to the action of direct current, first in a 20 per cent chromic acid bath heated to 65‹ C. and then in a 3 per cent oxalic acid bath at 35‹ C. After washing and drying, the surface is impregnated successively with solutions of ammonium chloride and silver nitrate and dried, giving a colourless photographic layer adapted for copying or exposure. The photographic reproduction, after fixing and toning, is coated with oil, fat or lacquer.
