Abstract: 602,806. Trough washers. HARVENGT, E. June 29, 1945, No. 16608. Convention date, May 20, 1944. [Class 82(ii)] In a trough washer wherein the evacuated products are collected in cones, a supported plug, consisting of a heap of the evacuated material, is formed at the discharge from the cone and the quantity of material discharged from this plug corresponds to a desired rate of discharge. As shown, a cone 3 formed in the bottom 2 of a washing trough has at its discharge end an adjustable perforated support 11 and an adjustable nozzle 16. A plug 10 of material discharged from the cone is formed on the support from which discharge may take place at the free end or over the sides. The bulk of the plug may be altered by varying the angle of the support and a second manually operated movable support may be slideably supported on the first support to vary the permeability of the latter. The action of the evacuation may be made dependent on the operation of the trough by means of a float 26 acting through levers 27, 28, 29, 29a and 30 to increase or decrease the opening into the cone and by a continuation of lever 30 and lever 25 to increase or decrease the discharge from the plug. A shaking action may be given to the support by cams or eccentrics Figs. 5 and 7 (not shown) and discharge may be further assisted by mechanical conveyers.

Patent GB-458090-A (GB)
Title: Improvements in methods of and means for automatically controlling vessels, aircraft and the like
IPC: G05D1/02
Filed: 1935-06-11
Abstract: 458,090. Automatic control systems. ALKAN, R., 70, Avenue de la Republique, Paris. June 11, 1935, No. 16800. Convention date, Nov. 27, 1934. [Class 38 (iv)] Body in motion.-The servomotor in a system for controlling vessels, aircraft and the like is actuated through a reversing switch constituted by the cross-connected contacts 21, 22 of a galvanometric relay, the coil 14 of which is energized by an alternating e.m.f., the time integral of which is proportional to the speed of veering or deviation from the desired direction, the coil also being subject to a control dependent on the angle of deviation applied by a leaf spring. The magnet 13 and the contacts are also subject to a follow-up control derived from the servomotor. A compass, or a gyroscope with two degrees of freedom and preferably compass-controlled, maintains rollers 2, connected to the poles of a battery, in a position corresponding to the desired direction, and a disc 7, mounted so as to partake of the movements of the craft, determines the position of co-operating contact segments 4 which are connected to the coil 14. A constantly running cam 11 oscillates the contacts 4 so as to produce an alternating e.m.f., in the coil the time integral of which is nil while course is maintained. This e.m.f. is also applied to an independently excited motor driving the disc 7 through a screw 6 so that upon divergence from the course the time integral of the e.m.f. becomes proportional to the speed of veering. The motor also drives a screw 35 to cause the displacement of a disc 36 of the relay in accordance with the deviation, which produces a displacement of an arm 27 controlling a spring 25. The servomotor actuating the controls thus becomes subject to the algebraic sum of forces which are proportional to the speed of veering and of the angle of veering. This servomotor also actuates a spindle 57 carrying a worm 49 which causes the follow up movement of the relay magnet and contacts. To change the course a differential may be inserted in the drive to the screw 35. The factor of proportionality in the control of the spring 25 may be adjusted by a slide 39, which alters the radius of arms 37 coupling the disc 36 to a disc 28. The disc 28 drives the arm 27 through a stud 30 adapted to ride out of a slot 29 and limit the force applied by the spring 25 on excessive deviation of the craft. The degree of follow up movement may be adjusted by a slide 53. To adapt the apparatus to contingencies the zero of the delay may be adjusted by a graduated nut 54 displacing the worm 49 on its spindle. The displacements of the craft and of the rudder, &c., are respectively indicated on scales 58, 62. The invention is applicable to control in respect of any axis of reference in an aircraft.

Patent GB-625361-A (GB)
Title: Improvements in or relating to bearings
IPC: C25D5/50
Filed: 1947-06-30
Abstract: 625,361. Coating of metals by electrodeposition. GLACIER METAL CO., Ltd., and TAIT, W. H..June 30, 1947, Nos. 1717S/47, 29711/47 and 12785/48. [Class 41] [Also in Group XXXIV] Bimetallic bearings and bimetallic materials for use in the manufacture of bearings are produced by electrodepositing ductile cadmium on a backing of steel, iron or copper alloy such as gilding metal, bronze or brass, from a perchlor. ate solution containing cadmium. To ensure a firmly adherent layer of cadmium on a backing of steel or iron, a coating of cadmium, e.g. 0.001 inch thick, is deposited from a cadmium cyanide bath prior to the deposit from the perchlorate solution and the composite material is then subjected to heat treatment, e.g. at 180‹ C., for about 1 hour, to secure strong adhesion between the coating and the backing. The first layer of cadmium may be treated, e.g. as cathode in perchloric or hydrochloric acid to remove residual cyanides from the pores. In the case of an iron, steel or copper alloy backing, a coating of nickel may be first deposited on the backing followed by the deposition of cadmium from the perchlorate solution with subsequent heat treatment, if desired. A nickel bath may comprise 300 grs./1. nickel sulphate (NiS0 4 7H 2 O), 30 grs./1. nickel chloride (NiCI 2 6H 2 O) and 3 grs./l. boric acid and have a pH of 4.6-4.2 and used at a temperature of 60-70‹ C. In all cases the backings may be subjected to a pretreatment, e.g. for the removal of grease, including an anodic etch. The backing may be a formed or partially formed shell of a bearing, a flat blank, or a continuous strip and in this latter case the continuous strip backing is fed through suitable baths and/or apparatus arranged in series. A perchlorate plating solution may comprise 60-120 grs./1. of cadmium perchlorate, 5-100 grs./1. free perchloric acid and .5-1 gr./1. of peptone or other suitable colloid such as liquoric or gelatine and if desired a small percentage, e.g..05 g./1. of beta-naphthol. Another solution contains 100 grs./1. cadmium perchlorate, 80-90 grs./1. free perchloric acid and about .5 gr./l. of peptone. The solution may be agitated during deposition to obtain higher current density and rate of deposition. A trace of indium is sufficient completely to inhibit the cadmium from dissolving freely in old oil, e.g. by depositing a film of indium on the cadmium layer and then diffusing to form a surface alloy.
