Title: Diesel engines constructed to operate on liquid fuel and or gas fuel
IPC: F02B11/02
Filed: 1970-09-11
Abstract: 1325349 Regulating diesel fuel engines SULZER BROS Ltd 11 Sept 1970 [11 Sept 1969] 43632/70 Heading F1B In a method of operating a diesel engine selectively operable on liquid or gas fuel, the respective quantities of which are controlled by a speed controller 44 through proportioning means, the gas fuel supply pressure is adjusted in dependence on a measured engine operating parameter so as to tend to maintain the value of the parameter the same for gas fuel operation as for liquid fuel operation at any particular value of speed controller output signal. Liquified natural gas is stored in a heatinsulated tank 1 and gas evolved in the tank passes via line 5, heat exchanger 6 and throttle member 11 to a compressor 12 e. g. a multistage centrifugal blower, connected through a valve 20 to a pressure reducer 23 and a pressure detector 22 and also to the engine gas valves (not shown). Modified gas pressure is introduced within bellows 24 which moves a tappet 26 which acts on an adjusting rod 28 to control the fuel delivery from pump 30. Rod 28 is interconnected by a lever 34 to the adjusting rod 35 of a pump 36 which hydraulically controls the operation of the engine gas valves, the pivot 50 of lever 34 being connected through a linkage 41, 42 to a speed controller 44 which is set by a lever 47. When the gas pressure in line 21 exceeds a lower predetermined valve the tappet 26 moves to the left to reduce the liquid fuel quantity and simultaneously increase the gas fuel supply. A torque measuring device 53 on the output shaft 51 acts through a cam and follower 54, 57 and a linkage 58, 60, 61 to vary the position of pivot 50. Lever 60 is pivoted at the end of a rod 62 connected to an astatic pressure regulator in the gas supply line. During gas operation when variations of the colorific value of the gas act through the speed controller to move pivot 50 the lever 60 acts on pressure regulator 63 to adjust the gas pressure. Elements 44, 34, 60 and 54 may be replaced by electrical or hydraulic devices.

Abstract: 1,069,606. Centrifugal separator. ALFALAVAL A.B. Oct. 14, 1965 [Oct. 14, 1964], No. 43664/65. Heading B2P. In an oil cleaner for i.c. engine comprising a cyclone-centrifuge assembly, the narrow end of the cyclone 4 extends towards one end of the centrifuge rotor 3 and the outlet at the narrow end of the cyclone opens into an axial inlet in that rotor end. The cyclone 4 has a tangential inlet 5 through which oil to be cleaned is pumped and an outlet 6, 7 for cleaned oil. The cyclone and the centrifuge rotor 3 are mounted in a common casing having parts 1,2 clamped together by a tie rod 9. For cleaning the rotor, the nut 11 on the tie rod is undone and the casing port 1 and the rotor 3 are lifted upwardly. A tube 15 clamped on the upper narrow end of the cyclone provides an annular passage 16 for sludge-containing oil from the cyclone, this oil being fed into the centrifuge rotor through holes 17 in the tube 15. Cleaned oil is discharge from the rotor via tubes 20 embedded in the rotor bottom and into which the oil passes through holes 24, the oil passing from the tubes via nozzles 23 into the interior of the casing from which it is removed via an outlet 8. The nozzles were to drive the rotor 3 by the reaction action of the oil jets.

Abstract: 1,194,597. Matrix displays. UNIVERSAL TELEWRITERS .(PTY) Ltd. 27 Sept., 1968 [27 Sept., 1967], No. 43992/67. Heading G5C. The elements of a matrix display comprise laminar shutters 7, contained in individual cells having windows 2, and they are moved into one of two stable positions by electrical means which induce translational forces directly in the shutters. As described these forces may be electrostatic, ferromagnetic or produced by A.C. eddy currents. Bistability is achieved by ramping the cell floor at 15, Fig. 8, or by hinging the shutters to a pivot (9, Fig. 5, not shown). In Fig. 7 the cells are scanned columnwise by a moving carriage bearing electromagnets 13; or the framework 11 itself may move. In Fig. 8, the shutters are actuated by an array of crossing, magnetic-force-inducing conductors O, S and R; thus energization of conductor R<SP>1</SP> will cause chutter 7 to be raised (to clear ramp 15) while energization of conductor C 1 O or C 1 5 will cause shutter 7 to open or occlude window 2, respectively.

Title: Improvements relating to implosion barriers for cathode ray tubes
Inventor: COLE ROBERT CROSBIE
IPC: H01J29/87
Filed: 1961-12-08
Abstract: 952,236. Cathode-ray tubes. GENERAL ELECTRIC CO. Dec. 8, 1961, No. 44002/61. Heading H1D. [Also in Division B5] An implosion barrier is applied to the face of a cathode-ray tube by providing a difference in pressure between the two sides of a deformable sheet spaced from the tube face so that the sheet is deformed towards the tube face to make an initial point contact (not necessarily at the centre of the tube face); the area of contact is then increased radially outwards from the initial contact area. The cathode-ray tube 18 is held in a cradle 17 which is moved upwards after the deformable sheet 29 is sucked downwards to contact the tube face by evacuation of the chamber 12. The deformable sheet may comprise polyvinyl butyral with triethylene glycol di-2-ethyl butyrate as plasticizer, as in Specification 950,350. This material is deformable at room temperature, but with other materials heating may be applied to aid deformation. The plasticizer may be applied in liquid form. Preferably the sheet is trimmed after being applied to the face of the tube to provide tabs for attachment to the usual tube holding strap. A protective thermoplastic sheet of cellulose acetate butyrate may be applied to the sheet 29 or the sheet may be laminated. The surface of the implosion barrier may be etched to reduce light reflection.
