Title: Shredding machine
IPC: B28C1/18
Filed: 1973-01-15
Abstract: 1413573 Granulating WATTS BLAKE BEARNE & CO Ltd 3 Jan 1974 [15 Jan 1973] 1944/73 Heading B5A [Also in Division B2] Clay, slag or mineral ore is shredded between a pair of contra-rotating plates 31 which are arranged with mutually inclined axes and have cutting elements 33 and apertures 32 so that the material is shredded and passes through the apertures. The cutting elements 33 are removably bolted to the back of the plates 31 and project through rectangular apertures 32 which are arranged in rows either radially of the plate or tangentially to a circle centred on the axis of the plate. The cutting plates 31 are mounted on shafts 29 having large diameter bearings 30 and driven by variable speed motors 27. Each drive assembly is mounted via rubber pads 24 to a plate 23 pivoted at 22 to an inclined platform 20. Wedges 26 between the platform 20 and the plate 23 are changed to alter the inclination of the cutter plates. A casing 36 surrounding the plates 31 is open at the bottom 38 to permit the material to fall on to a discharge conveyer 40. A curved member 41 with flared ends is located to prevent material passing under rather than through the cutter plates 31.

Title: Improvements relating to alloy cast iron rolls
IPC: B22D15/00
Filed: 1943-02-05
Abstract: 568,888. Casting rolling-mill rolls. MOND NICKEL CO., Ltd. Feb. 5, 1943, Nos. 1983 and 1984. Convention dates, Feb. 13, 1942. [Classes 83 (i) and 83 (iv)] [Also in Groups II and VIII] To produce an alloy cast-iron roll, with a hard martensitic roll surface and at least one machinable neck of the same composition as the body of the roll, the roll is cast from a melt that on normal cooling to atmospheric temperature would have a martensitic structure resulting from the transformation of austenite and the cooling of the neck is arrested long enough to transform the austenite to a machinable matrix structure, the body being allowed to cool in such a way that the austenite is transformed to an essentially martensitic structure. To effect the transformation of the neck structure, the neck is maintained within the range 900-1100‹ F., and the roll after cooling may be subjected to a stress-relieving heat treatment, e.g. heating to 400-600‹ F. and then cooling slowly. The machinable matrix structure is composed of decomposition products of austenite other than martensitic and sorbite and contain at least 50 per cent of pearlite. The treatment is referred to of an alloy cast-iron roll containing 2.75-3.75 per cent of carbon, 0.25-1.75 of silicon, 0.15-1.65 of manganese, 3.5-6.5 of nickel and 0.5-2.25 of chromium, and may contain in addition up to a total of 10 per cent one or more of molybdenum, vanadium, copper, tungsten, boron and tellurium. The cooling of the necks may, for example, be arrested by applying heat to them while the rest of the roll is allowed to cool, or by supplying electrical energy to heating coils embedded in the sand round the necks while the roll is cooling in the mould.

[Classes 36 and 37] A high voltage insulator comprises an insulating body 3 separating a conductor 1 from a mounting flange 2, an internal electrode 4 for testing the internal condition of the insulator and at least one other electrode for testing the surface condition of the insulator. The mounting flange 2 may be insulated from the supporting structure and used as the surface electrode, or one or more wire wrappings 7, 8 may be arranged on the surface of the insulator 3 near to the flange 2, which may then be in contact with the supporting structure. The internal and surface condition of the-bushing may be measured by an apparatus shown in Fig. 4, comprising a high potential source of alternating current 16, and a micro-ammeter 16. Three terminals 12, 13, 14-are provided, terminal 14 together with the earth terminals of the generator and meter being connected to earth. For testing the surface condition of the insulator the flange 2 and electrode 4 are connected respectively to the terminals 13 and 14, the conductor 1 being connected to terminal 12. The internal condition of the insulator may be tested by connecting conductor 1 to terminal 12 and the flange 2 and electrode 4 to terminals 14 and 13 respectively. If the surface conditions of the ends of the insulator on each side of the flange 2 are to be tested separately one of the wire wrapping electrodes 7, 8 is connected to terminal 13, the other wire electrode and the electrode 4 being connected to earth through the terminal 14. In a modification the electrode 4 is connected to a third wire wrapping electrode placed between the flange 2 and one of the electrodes 7, 8.

Abstract: 538,415. Fluid-pressure servomotorcontrol systems. BENNETT, R., and EWING, A. Feb. 10, 1940, No. 2619. Addition to 530,641. [Class 135.] An apparatus as claimed in claim 2 of the parent Specification is arranged to compensate for any changes in pressure in a fluid system in accordance with variations in the loading pressure exerted by the system on a diaphragm controlling the reducing valve. Fig. 1 shows the invention applied to the control of a variable stroke pump in accordance with the pump delivery pressure. The stroke-varying gear is operated by a double-acting piston 60 controlled by a relay piston valve 24 actuated by a spring-loaded piston 14. The valve 24 works in a movable ported seat 56 coupled to the piston rod 61 by a link 66, lever 64 and pin and slot 68 to give a follow-up action. The pressure acting on the piston is varied in accordance with the pump delivery pressure in the conduit 12 by a valve 2, 2a working in association with an adjustable leak 6, 6a. The valve 2, 2a which is actuated by the pressure in the conduit 12 acting on a diaphragm 10 comprises a pair of differential pistons 1, 2 of which the piston 2 has longitudinal passages for the fluid and is formed with a head 2a adapted to co-operate with a seat 2b. In a modification the piston 14 is arranged to actuate a double-beat valve in the main conduit.

Abstract: 486,049. Impedance networks. HADFIELD, B. M. Feb. 1, 1937, No. 2849. [Class 40 (iii)] A series-tuned circuit whose output is taken from either the condenser or inductance has the input voltage reversed in phase and mixed with the output voltage. Thus, in Fig. 2, the windings S1, S2 feed the circuit CL and the output terminals respectively in opposite phase, and the circuit acts as a low-pass filter, since at high frequencies the impedance of CL is predominantly that of L so that outputs from S1, S2 are equal and opposite. When the output is taken from across the condenser, the circuit acts as a highpass filter. The circuits are employed to isolate a sinusoidal oscillation from an impulsive oscillation.
