Title: Improvements in or relating to internal combustion engine control means
Inventor: COOK HENRY
Filed: 1955-01-05
Abstract: 811,707. Gas turbine plant. ROLLS-ROYCE Ltd. Feb. 16, 1956 [Jan. 5, 1955], No. 365/55. Class 110 (3). [Also in Group XXIX] Control means for a gas turbine engine comprises means to produce a fluid pressure which is representative of the engine rotational speed, first pressure-responsive means connected to respond substantially instantaneously to said fluid pressure and arranged to load a fuel control member in the sense to cut down the fuel supply on increase of speed, second pressure-responsive means arranged to load the control member in opposition to said first pressure-responsive means, and a restrictor to delay the response of said second pressure-responsive means to change of said fluid pressure on increase of engine speed. In an embodiment, a variable swash-plate fuel pump 10 supplying fuel injectors 12 through a throttle valve 11 is adjusted by a servo-piston 15 under the control of a valve member 20 carried by an arm 21 and subjected to the forces of a spring 22, an evacuated bellows 27 exposed to barometric pressure, and a piston 23 acted upon by pressure of fuel taken from a point upstream of the throttle valve 11 and modified, after passing through a restriction 29, by a leak-off valve member 31 actuated by a spring-loaded bellows 37 and a bellows 38 acting through a spring 51. An engine-driven, fixed capacity, positive displacement pump 40 discharging through a temperature-adjusted valve 42 produces a pressure in a conduit 52 as a function of the corrected rotational speed of the engine which pressure is applied directly to the bellows 37 and through an adjustable viscous restriction 47 to the bellows 38 so that a rapid increase of speed causes a corrective adjustment of the valve member 31 by the bellows 37 to a greater extent than is caused by the delayed resultant of the pressure acting on the two bellows 37, 38. A non-return valve 49 prevents the restrictor 47 from being effective during deceleration.

Title: Free float type steam trap
Inventor: FUJIWARA KATSUJI
IPC: F16T1/22
Filed: 1968-01-03
Abstract: 1,207,197. Steam traps. K. FUJIWARA. 3 Jan., 1968 [11 Jan., 1967], No. 517/68. Heading F4U. [Also in Division F2] In a free float steam trap, a bimetal device prevents the float from shutting off discharge from the trap when the contents of the trap are below a predetermined temperature so that the formation of an air lock in the trap at start-up is prevented. As illustrated, the float 5 normally contacts or clears a valve seat 3 according to the level of condensate in the trap to control the discharge of condensate through a passage 16. However, when the contents of the trap are below normal working temperature, a bimetal disc 4 flexes to the position shown to prevent the float from contacting the valve seat. When steam enters the trap, the disc 4 flexes to the right to a position in which the valve seat projects through a central opening in the disc and in which the float may operate normally. If an air lock develops during normal operation, the trap will cool by radiation to a point at which the disc 4 unseats the float to discharge the air. The bimetal device may be of U-section, Figs. 8 and 9 (not shown), one arm being attached to the seat and the other being free to act on the float. The bimetal device may be located beneath the float, Fig. 5 (not shown), in which case the device may take the form of an apertured rectangle, Fig. 7 (not shown).

Title: Improved planographic printing plate
IPC: B41N3/03
Filed: 1958-01-06
Abstract: 885,086. Photo-sensitive material for printing plate production. MINNESOTA MINING & MANUFACTURING CO. Jan. 6, 1958 [Jan. 4, 1957], No. 533/58. Drawings to Specification. Class 98(2). A thin smooth metal sheet is provided with a water insoluble hydrophilic isolating layer and then a sensitising layer of a material which on exposure to light becomes insoluble, firmly adherent ink repellent and water receptive. For lithographic plate production by exposure under a positive two methods are detailed, the first of these requiring an inkaccepting layer between isolating and sensitising layers; thus in Example 1 an aluminium foil is cleaned, treated with sodium silicate solution and washed to provide the isolating layer, treated as with a para-diazodiphenylamine para-formaldehyde resin and uniformly exposed with ultra-violet light to provide the ink-accepting layer, and then provided with the sensitising layer of which a preferred composition is a similar diazo resin together with polyacrylamide applied in aqueous solution. In use the foil so prepared is exposed through a positive with ultra-violet light and washed with water to remove unreacted sensitiser, leaving the underlying, ink-accepting image which may be further treated as with printers' developing ink before installation on a lithographic press. In the second method, Example 2, a material as of Example 1 but not provided with the ink-accepting layer between isolating and sensitising layers is exposed directly under a positive, swabbed with water or gum arabic solution to remove unexposed image areas of the sensitiser, wiped with an alcoholic cupric chloride solution to effect etching in the image area, the underlying isolating layer and perhaps also the surface of the aluminium foil being chemically attached and metallic copper plated out but the insoluble non-image areas being unaffected; methyl alcohol or equivalent is then used to remove unreacted cupric-chloride and byproducts, and the plate is ready for the press but preferably the image areas are further strengthened by application of a vinyl lacquer. A heptane solution of an alkyl silicon halide may be used in place of the cupric chloride solution. The use of numerous other metal sheets and materials for forming the isolating and sensitising layers especially for the procedure of Example 1 is described, and other uses of the products than for lithographic procedure such as the production of metal name plates, signs, maps and wiring diagrams are indicated.

Convention date, Jan. 9, 1933. Addition to 405,202. [Classes 83 (ii) and 83 (iv).] A machine for subjecting can bodies &c. progressively and circumferentially to a wave bending sufficient to stress the metal beyond its elastic limit by driven bending elements applied both internally and externally of the bodies as described in the parent Specification, comprises units each having internal and external revolving wave bending rolls, means for driving the rolls, and means for introducing the bodies between the rolls of successive units for treatment by displacing them for their entire length and for removing the treated bodies by oppositely displacing them beyond the rolls. A base J, Fig. 2, supports a stationary shaft H carrying fixed cams L, M and a stationary gear N. Rotatable on the shaft H, through pinions d, e and a belt pulley g, are carriers P, Q, the latter consisting of an end disc h and a cylindrical member i secured to the carrier P. As the carrier P rotates, planet pinions a, engaging the gear N, rotate internal rollers 2 which are mounted in slides n disposed in slots m in the carrier. Each slide supports a pair of external rollers 4, 5, Fig. 3, connected to a fixed shaft s by a toggle linkage t, u adapted to bring the rollers 4, 5 up to or away from the roller 2 as an arm r on the linkage is rocked by a roller q engaging a slot p in the cam L. The cam M has a groove 112 in which engage rollers z, each carried by a yoke y supporting a pair of rods w. Guides 34, 35 on the rods ware drawn together by a spring, but separated, when a can body is being fed to them, by a stop on a reduced portion j of the cylinder i engaging a projection on the hub 116 of the guide 34. The can bodies fall down a shoot R on to the hub members 116, 117 of the guides 34, 35 and as the carrier Q rotates they grip the body prior to the rods w being moved by the roller z and cam M to feed the can body between the rollers 2, 4, 5. The cam L now brings these rollers together and body is subjected to the wave bending as far as the station B<4>, Fig. 3, where the rollers 4, 5 are slightly withdrawn to permit further rolling to remove creases from the body. At the station B<6>, the rollers are wholly retracted, the guides withdraw the body therefrom and an ejecting lever T, Fig. 12, engages a roller 135, Fig. 3, to eject the body from the machine.

Class 138(1) [Also in Groups XXVIII and XXIX] A vehicle windscreen washer is characterized in that the pump for pumping liquid from a receptacle A, Fig. 1, to at least one nozzle B, comprises a body formed by an elastic cylindrical tube having intake and discharge valves at its ends, the tube being positioned between a base plate and a plate pivoted on the former the pivoted plate being operable to flatten the tube. As shown in Fig. 1, the receptacle A for cleaning liquid L, communicates with the pumping means E connected by a tube D to the nozzle B directed towards the windscreen C, the pumping means being operable manually by a knob G and flexible means F. If desired the pumping means E may be disposed outside the receptacle e.g. mounted on the lid thereof or interposed in the tube D between the receptacle and the nozzle. Refering to Figs. 2 and 3 the pumping means E comprises a flexible cylidrical tube 1 fitted at its ends with hollow sockets 2, 3 which are supported in lateral shoulders 10a of a, plate 10 engaging the tube 1. The sockets 2, 3 are connected at 2a, 3a with the liquid L in the receptacle A and the nozzle B, respectively, and house spherical caps 6 each perforated at 7 and fitted, as at 8, with a flexible circular mambrane 9, the caps and membranes constituting a suction valve 4 and a discharge valve 5. Pivoted in a part 10b of the plate 10, by a tongue 11a, is a plate 11 of generally trapezoidal shape and bearing on the tube 1, the plate 11 being connected at at 12a to a flexible cable 12 passing through a hole 10c in the plate 10 and through a sheath 13, the cable' 12 and sheath 13, constituting the flexible means F, Fig. 1. The plate 11 may be urged to the position shown in Fig. 3 by a spring. On operating the knob G, Fig. 1, the cable 12 causes the plate 11 to flatten the tube 1 and discharge liquid through the valve 5. When the knob G is released the valve 5 closes and liquid is drawn through a valve 4 to replenish the interior of the tube 1. The plate 10 may be secured to the lid of the receptacle. In a modification the pumping means E is supported within the receptacle by the lid and a tongue extending from the plate 11 passes through an arcuate slot in _the lid and is connected to the cable 12.
