Title: Apparatus for shaping and curing tyres
IPC: B29D30/06
Filed: 1962-10-15
Abstract: 989,203. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. Oct. 15, 1962 [April 16, 1962], No. 38890/62. Heading BSA. A tyre press in which internal shaping pressure is applied while the mould halves are closing has a sensing arm which is driven by the mould closing mechanism and which moves out of the mould at a predetermined rate (the desired rate at which the tyre should be expanded) and has a sensing means at the end of the arm which controls the internal shaping pressure and will interrupt this pressure if the rate at which the tyre expands exceeds the rate at which the arm moves out of the mould. As described, two such sensing arms 76L, 76R are incorporated in a dual tyre press (Fig. 2) in which uncured tyre bands B are shaped by upper and lower moulds 20, 21 and diaphragmtype air bags 25. The arm 76R is connected to a sleeve 119 (Fig. 4) and is moved by a piston and cylinder 128 holding a cam follower 122 against a cam 78R. The cam 78R is mounted on a rod 107 and is turned by the mould closing mechanism via chain drive 100 (Fig. 2) rod 97 (Fig. 4) and bevel gears 95, 103. The cam 78L is mounted on a sleeve 105 and is driven by bevel gears 95, 104 in the opposite direction to cam 78R. The cam 78R has surface 141 (Fig. 5) which holds the arm in its innermost position, surfaces 142, 143, 144 which move the arm out at the desired rate and surface 145 which holds the arm at its outermost position. The arm 76R has sensing means 79 which may be an electric switch (not shown) which controls the shaping pressure by a solenoid operated valve (not shown) so that if the tyre band B touches the sensing means the shaping pressure is interrupted. Various other sensing means may be used, e.g. photo-electric or pneumatic means. Specifications 652,367, 704,797, 741,814, 759,546, 816,833, 817,335 and 846,250 are referred to.

Abstract: 1,103,340. Waveguide polarization rotators. MARCONI CO. Ltd. 11 July, 1966 [20 Sept.. 1965], No. 39951/65. Heading HlW. [Also in Division H4] A TR arrangement comprises rectangular waveguides T, R coupled at right-angles to a circular waveguide C and a polarization rotator P between the waveguide C and a horn H. Transmitted and received waves have mutually orthogonal polarizations in guide C whereby they are coupled respectively to guides T and R. Rotator P consists of a rotatably arranged 180 degrees phase-shifter which rotates both waves through an angle 20 where 0 is the angular adjustment of the phaseshifter. The rotator may consist of a dielectric vane V which produces no rotation when # = O, i.e. when the vane is in one of the two planes containing the axes of guides T and R. A section of elliptical waveguide may be used instead of a vane. Alternatively, the phaseshifter may consist of two independently rotatable 90 degrees sections. In this case, circular polarization may be obtained by rotating the section nearer the horn through 45 degrees and setting the other section at zero.

Title: Rotary positive displacement compressors of the screw rotor type
IPC: F04C18/16
Filed: 1964-10-01
Abstract: 1,067,913. Rotary screw compressors. SVENSKA ROTOR MASKINER A. B. Oct. 1, 1964 [Oct. 1, 1963], No.39974/64. Heading F1F. In a positive displacement compressor of the wet or flooded intermeshing screw rotor type, the main barrel portion 10, Fig. 1 of the casing including the intersecting co-planar bores (14), (16), Fig. 2 (not shown) is relieved at 40 to form an abrupt helical shoulder 42 and a radially inwardly extending lip 44 which is a close running fit with the male and female rotors 18, 20 respectively. This prevents the cooling and sealing liquid injected into the casing through openings 36 on the intersection 38 of the bores on the high pressure side of the working space being mixed with the increasing gaseous fluid passing through the axially directed inlet port 22 and so transferring heat thereto. It also reduces so called "churning" losses brought about by the blow-back from the high pressure end of the compressor through the running clearances between the rotors and the bores, the lip preventing gas and liquid being returned through the inlet port 22.
Patent GB-925049-A (GB)
Title: Resilient mounting
IPC: F16F1/371
Filed: 1961-11-14
Abstract: 925,049. Springs. LORD MANUFACTURING CO. Nov. 14, 1961 [Dec. 12, 1960], No. 40647/61. Class 108(3). A resilient support, which requires less space for the same vibration isolation and which also has large energy absorption under shock, comprises a column of elastomer 1 such as natural or synthetic rubber having end plates 2, 3 and a preloading- spring means 7, 8a which limits the area of the body in which bulging can take place. The spring means 7, 8a consists of a split metal band 7 which is preloaded, into its closed position, by an encircling garter spring 8a the contracting force of which on the band 7 increases the overall stiffness of the support while at the same time providing an incremental spring rate which is substantially identical with that of an unbanded mounting over the required working range. On load the body bulges at 9 the split 10 between the ends of the band 7 opening up after the expansive force on the band exceeds the contracting force of the spring 8a. The initial stiffness of the support is controlled primarily by varying the width of the band 7, the point 14 at which the characteristic 11, Fig. 5, changes from stiff to less stiff can be regulated by varying the degree of preloading exerted by the spring 8a. Lubrication between the band 7 and the body 1 reduces the stiffness after the band opens. In order to prevent the band 7 from slipping out of place the body can be grooved externally alternatively, the band and body 1 can be provided with co-operating recesses and projections. The characteristics of the body may also be modified by leaving a uniform, or non-uniform, space between the body 1 and the band 7 so that the load would initially follow the characteristic 5 of the unbanded support before transferring to the stiffer spring rate instead of one wide band 7 several narrower bands arranged side-by-side may be used, the spring action being either due to the inherent resilience of the bands or, to supplementary springs such as the garter spring 8a. A garter spring 8a may be used on its own if it is wound so that its coils are held against each other under initial tension.

A cutting-machine comprises a work clamp 40 reciprocable by a reversible hydraulic motor 45, the hydraulic circuit to the motor including supply lines 62, 63, Fig. 2, with each of which is connected a pressure control valve 65, 70 respectively for establishing separate pressure conditions for the operation of the motor in opposite directions, the valve 70 being adjustable so that a relatively high pressure is supplied during the clamping operation and the valve 65 being adjustable so that a relatively low pressure is supplied for retaining the clamp in the inoperative position: Pressure fluid is supplied by means of a low capacity pump 41 under the'control of a valve 60 which is normally biased to a position to cause raising of the clamp. The piston 46 of the motor 45 is connected to the clamp 40 by means of a link 48 and a crank 49 secured to a shaft 50. The knife 10 is reciprocable by a reversible hydraulic motor 25 which is supplied with pressure fluid by means of a high capacity pump 31, the hydraulic circuit including supply lines 37, 38, Fig. 2, and a self-centring control valve 30. The valve 30 is operated by solenoids 35, 36 which are energized selectively to cause working and return strokes of the knife. When neither solenoid is energized, the knife is maintained in its inoperative position by relatively low pressure. A valve 34 controls the pressure produced, by the pump 31. The valve 60 is operable by means of a lever 90, Fig. 3, or treadle 92. Following closing of the valve 60, a lever 95 is moved to actuate an electric switch 96 to complete a circuit to a switch 97. The switch 97 is operable by a contact 105 or 106 on a bell-crank 16 to energize solenoid 35 or 36. To eliminate drifting of the knife, when in its inoperative position, caused by fluid leakage from the motor 25, a pressure line 75, Fig. 2, having a restrictor 77 is connected from the output line 58 leading from pump 41 to the side of the cylinder 27 causing raising of the' knife. To ensure that the clamp and knife return to their inoperative positions as rapidly as possible, a valve-controlled pressure line 80, Fig. 4 (not shown), is connected from line 37 at one end to line 62 at the other end, the pressure line 75 being omitted.
