Title: Improvements in and relating to track laying vehicles
IPC: B62D11/08
Filed: 1953-02-10
Abstract: 725,686. Steering vehicles by declutching and braking. GAUTHIER, R. Feb. 10, 1953 [June 10, 1952], No. 3764/53. Classes 79(2) and 79(5). In an endless track vehicle, forward and reverse gearing interposed between the engine and the tracks is controlled by servomotors supplied from a hydraulic or pneumatic pressure source which also supplies servomotors controlling declutching of the tracks and effected by displacement of brake pedals for the tracks. In the preferred embodiment the engine (not shown) separately drives a power take-off shaft 13 and a shaft 16, the shaft 16 being connected through the forward and reverse gearing 17, change speed gearing 12, a shaft 11 and bevel gearing 10, 9 to a shaft 6. The shaft 6 carries at each end by means of keyways the driving portion 7 of a steering friction clutch, the driven portion 4 of which is integral with a track sprocket 2 and a brake drum 3. The steering clutches and the forward and reverse control levers 18, 19 of the gearing 17 are controlled through the fluid pressure servomotors and the brakes 14, 14<SP>1</SP> co-operating with the drums 3 are controlled directly by the pedals 15. The servomotors are supplied from the reservoir 30 charged by a compressor 31, the cylinders 20, 22 for the levers 18, 19 being supplied through a manually operated valve 27 and the cylinders 33 for the clutches being controlled by valves 36, 36<SP>1</SP>. The valves 36, 361 carry levers 37, 37<SP>1</SP> connected to cylinders 39 ; within each cylinder is a spring 41 abutting a piston 40 connected to the brake pedal 15, the arrangement being such that the pedal 15 first disengages the clutch and then applies the brake. After the pedal's initial movement the lever 37 engages a stop 42, subsequent pedal movement being accommodated by the spring 41.

Abstract: 953,613. Measuring electrically. E. K. COLE Ltd., E. C. W. FIELDER, and N. L. ALLEN. Jan.28, 1963 [Feb. 1, 1962], No.3825/62. Headings G1N and G1U. The resistance of a load cell is measured in a bridge circuit whose unbalance signal is compared with that from a preset bridge, so that when the load is above a predetermined value the combined bridge output changes phase and causes an alarm to be initiated. As shown (Fig. 1), the output from the measuring bridge 1 is algebraically added to that from a subsidiary bridge 2 energized by the same oscillator 3, and the resulting signal is amplified and shown on a meter 6, and also phasedetected at 3 to operate an alarm relay A when the phase of the resulting signal changes. Relays B, C give virtual signals at other predetermined loads. Automatic temperature compensation is provided. The bridge may be energized with square wave A.C. or D.C. which is chopped before amplification.

Patent GB-385773-A (GB)
Title: Manufacture of inorganic pigments
IPC: C09C1/04
Filed: 1932-02-11
Abstract: Inorganic pigments are obtained by thermal combination of zinc oxide with an oxide or oxides of an element or elements of the type MeO, other than cobaltous or nickelous oxide, whereby mixed crystals or solid solutions are formed.  Oxides specified are those of cadmium, magnesium, iron, manganese, beryllium, ruthenium, osmium, palladium, platinum, copper, calcium, rhenium, and masurium.  Metal compounds such as sulphates or chlorides, capable of forming oxides by thermal dissociation, may be used for the reaction, and the latter be carried out in a reducing atmosphere when necessary to avoid formation of higher oxides such as those of iron or manganese.  Temperatures of 800-1100 DEG  C. are requisite for the reaction, which may be assisted by addition of fluxes such as potassium chloride of sodium sulphate.  Reference is made in the Specification to mixed crystals of cobalt oxide with magnesium, manganous, or nickleous oxide. Specification 17031/96, [Class 95, Paints &c.], is referred to.

Title: Improvements in the manufacture of hollow ingots and castings
IPC: B22D7/04
Filed: 1954-02-15
Abstract: 760,501. Casting-processes. ENGLISH STEEL CORPORATION. Ltd., and SMITH, E. W. Nov. 5, 1954 [Feb. 15, 1954], No. 4397/54. Class 83 (1). Hollow-ingots or other castings are made by lowering into a partially-filled mould, so as to displace molten metal to the requisite height, a cone having an outer sheath spaced from an inner heat-absorbing body, so that the sheath or initial entry of the cone into the molten metal, will collapse against the inner body, and subsequentially revert substantially to its original shape to permit withdrawal of the inner body. The core comprises a sheetmetal sheath 7 and a solid metal supporting- member 8 of a diameter slightly less than the internal diameter of the sheath, and supported therein by lugs 10 and a bar 11. The cone is centred by a spider 2 bolted to the top of the mould 1. After inserting in the melt and remaining for a determined period, the body 8 may be withdrawn from the sheath and a similar body of slightly smaller diameter inserted if further heat extraction is desired, this process being repeated if necessary. In a modification the body in the sheath is split longitudinally into four segments which yield radially under the contraction of the metal, and in a further modification the body is made of a number of discs threaded on to a centre spindle, which discs may also be split axially to allow radial contraction. The cores may be bored to allow circulation of coolant such as water or air.

Furnace details. - A polyphase or other furnace having each electrode adjusted by an electric motor in accordance with the current is provided with a separate solenoid or electro-magnet placed in shunt between each electrode and the bath so as normally to be inoperative but so as to act on the regulating mechanism to cause raising of the electrode if the pressure between the bath and electrode becomes too low or if the supply current is cut off. The solenoid or electro-magnet is provided with a spring opposing the magnetic action with a force which increases considerably when the armature is nearest the magnet. As shown, the blade spring D<7> supports a cross-pin D<6>, on a stem carrying the armature D<2>, and is slotted at its ends to slide under studs D<8>. The electro-magnet consists of square stampings with an internal pole-piece preferably integral therewith and surrounded by the winding. The stem D<4> is attached to a lever, the other end of which operates on the controlling member of a Thury regulator. This member is normally actuated by a current coil and a spring.
