IPC: G03F9/00
Filed: 1950-03-29
Abstract: 676,147. Printers' composing-appliances; printing-surfaces. CHRISTEN, E. March 29, 1950 [March 30, 1949], No. 7876/50. Classes 100 (ii) and 100 (iii). As a step in a multi-colour printing process, the formes are accurately registered outside the press by making, on a transparent sheet accurately positioned in the press, a proof of a first forme already located in the press, the proof being removed from the press and fixed by means of a clamping device to the reference limb of the chase of a further forme, at a position corresponding to its position relative to the chase of the first forme, after which the elements of the further forme are checked accurately and registered correctly with respect to the first forme by examination through the proof. Bronze powder can be applied to the proof before it is dry to increase the contrast. The clamping device comprises a rod-like carrier 1, Fig. 2, extending the whole length of the reference limb of the chase and secured thereto by two or more brackets 2, which are fixed to the chase by means of screw levers 14 and grip the carrier 1 between jaws 15, 16 by clamping screws 18. The jaws may be omitted, the carrier 1 having a groove with an inclined surface to engage the screws 18. Sliding transversely in recesses in the carrier are four arms 3 overhanging the chase and carrying clamping members 4, 5 to grip the edge of the proof, the arms being clamped in the desired position by set screws 8 and cover plates 7, at least one of the arms having a scale co-operating with a mark on the carrier. The clamping member 4, Fig. 4, is secured to the arm, one member 4 being common to each adjacent pair of arms. The member 5 is adjustable vertically by means of a head 12 and a spindle 11 held against axial displacement by tapered pins 13 projecting into an annular groove on the spindle. The arms 3 are adjusted so that the stops for the proof, formed by the upright limbs of the members 4, are the same distance from the limb of the chase as is the front stop in the printing machine. When the proof is inserted and clamped, it is at the level of the type on the forme. The device can be secured to the chases of further formes, which can be checked and registered by means of the same proof.

Title: Improvements in or relating to mixing valves for internal-combustion engines
IPC: F02M1/00
Filed: 1942-06-23
Abstract: 558,229. Carburetters ; regulating. SWAIN, C. D., and TILLING, Ltd., T. June 23, 1942, No. 8625. [Classes 7 (ii), 7 (iii) and 7 (vi)] The change-over from combustible mixture supplied from a carburetter 19 to the induction pipe 18, to producer or other gas from a connection 20, is controlled by a rotary or slide valve 10 having ports 12, 13, 14 corresponding to the three connections. As the carburetter is cut out, the producer gas &c. is brought gradually into action, until the change-over is complete. The valve 10 is actuated manually by a rod 42 and lever 24, and means are provided for simultaneously adjusting the throttle 36, the ignition distributer (not shown), and a petrol tap 40. The throttle lever 31 is engaged by the end of a lever 28 pivoted at 29 and connected by a pin and slot 30 to the lever 24, the lever 28 being also connected to a snap-over lever 41 on the petrol tap, and to a Bowden cable 37 leading to the ignition distributer. When the producer gas is in use, air is admitted at 43 past a hit-and-miss valve 46 rotated by a lever 48 and rod 49, the valve having two openings which come into action successively. The air is admitted by a passage 50 to a point in the connection 20 ahead of the valve 10, and a throttle 51 in the passage 50 is coupled to the main throttle 36 ; or the valve 51 may be suction-actuated. The opening 16 for inlet of the producer gas is made of larger area than that 15 leading from the carburetter. The valve 10 is lubricated by oil sucked in through passages 60, 61, 62 by the effect of the entering producer gas upon short passages 63. In alternative arrangements, the carburetter 19 or the induction pipe 18 may be at the end of the valve 10 opposite the connection 20 ; or a small additional carburetter may be arranged there with connections which bring it into action when producer gas is in use and the throttle 36 is opened a predetermined extent, thus providing extra power for hill climbing when on producer gas.

Title: Improvements in power plant incorporating internal combustion engine-driven compressors supplying motive fluid to a prime mover
IPC: F02B71/06
Filed: 1943-06-30
Abstract: 595,297. Gas'turbines or engines. ENGLISH ELECTRIC CO., Ltd., and WELSH, R. J. June 30, 1943, No. 8651. [Class 110 (iii)] [Also in Group XXVII] In a gas-turbine or gas-engine plant supplied with working-fluid by two or more gas generators A, B, the generators are inter-connected so as to run at the same speed and deliver their pressure surges of gas to an inlet manifold 7 simultaneously. Working fluid may be (i) compressed air, (ii) exhaust gas from the generator cylinders or (iii) a mixture of the two. The generators may be rigidly interconnected, or electrical or hydraulic synchronising means may be used to cause them to run at the same speed. The control means may govern the amount of fuel injected by each pump 5, or the timing of the fuel injection, or vary the throttle position at the air inlet to the compressor, or vary the pressure in a buffer cylinder P. Another method mentioned in the Specification is for the synchronising means to alter the position of an oscillating mass in relation to its fulcrum, and thereby vary the effective inertia of the moving parts of the gas generator. The Figures show one form of plant in which a turbine 8 is supplied with gas by two gas generators A, B, and a servo-motor 24, supplied with fluid by a pump 18. A speedgovernor 10 acts on a rod 13 to alter the position of three-armed levers 15. Air enters each compressor cylinder through an inlet 2, and is forced out by a piston 1b through a pipe 3 to the engine-cylinder. A buffer piston 1c is provided oil the end of the piston rod. The fuel-pump is controlled by' a fuel-regulating rack 5a. Exhaust gas passes through pipes 4. The lever 15 for B turns about a fixed pivot 17. The pump 18, supplied with fluid by a reservoir 21, is driven by the generator B and delivers fluid into a cylinder 24. According to the positions of pistons 25, moved by the generator A, fluid passes through one port 24c or 24d, the other acting as an exhaust, and moves a piston 29 to vary the position of a cam 30. The latter acts on a roller 31 and varies the tilt of the lever 15 for generator A. Non-return and pressure-relief valves 22, 27, are provided. At the end of the stroke of piston 19, a groove 19b connects with the inlet 18a. The two generators A, B may be maintained out of stop by some desired amount by adjustment of the piston-valve 25, but the pressure impulses must reach the turbine inlet at substantially the same time. Where there are more than two generators, one may be made the master, and others follow it. An electriccontact device may be used in place of the pump 18, a device which interrupts the circuit in place of the valve 24, and an electro-magnet or motor in place of the servo-motor 28.
Patent GB-581520-A (GB)
Title: Improvements in and relating to bonding fabrics to natural and synthetic rubber
IPC: C08J5/06
Filed: 1944-05-08
Abstract: Agents for bonding regenerated cellulosic, nylon or glass fabrics to natural or synthetic rubber, e.g. poly-2-chloro-1.3-butadiene or poly-1.3-butadiene, are emulsions or dispersions of modified alkyd resins in aqueous solutions of either protein material or partial resinification products of monohydric or polyhydric phenols and aldehydes.  The alkyd resins are modified with semi-drying oils, linseed oil, linseed-tung oil mixtures, or thermohardening urea-formaldehyde resins.  The latter type may be mixed with a non-drying oil modified alkyd. Suitable proteins are casein, gelatine, glue, blood albumin, egg albumin, or corn or bean proteids. Casein or similar proteins may be dissolved with the aid of ammonia, sodium phenate or sodium trichlorphenate.  The preferred partial resinification products are those from resorcinol, phloroglucinol or resorcinol and formaldehyde, acetaldehyde, benzaldehyde or furfural. The solutions of these partial condensation products may include resinification catalysts, e.g. sodium hydroxide or hexamethylenetetramine.  The bonding agent is applied to the fabric by dipping, spreading, brushing or spraying, the fabric dried and, if desired, heated to temperatures up to 155 DEG  C.  The natural or synthetic rubber stock is then applied to the fabric and vulcanized. In example 1, a solution of a urea-formaldehyde modified glyceryl phthalate resin in b -ethoxyethyl alcohol is emulsified in aqueous ammonia, and aqueous ammoniacal casein is added with stirring.  The emulsion is used to impregnate rayon tyre cords which are then pressed on to a layer formed from a rubber mix containing smoked sheet, zinc oxide, carbon black, stearic acid, sulphur and mercaptobenzthiazole, and the layer is vulcanized Comparison with untreated cords applied to a similar layer showed better adhesion for the treated cords.  Example 2 is similar, but employs a long oil linseed oil-modified glyceryl phthalate resin.  Example 3 is also similar to example 1, but employs an emulsion containing mixed urea-formaldehyde modified glyceryl phthalate resin and castor oil-modified alkyd resin together with a partial condensation product from resorcinol and formaldehyde.  Example 4 employs a resorcinol-formaldehyde partial condensation product in conjunction with a long oil linseed oil-modified glyceryl phthalate resin. Specifications 461,650 and 477,380 are referred to.
