Title: Improvements in or relating to fuel injection pumps for internal combustion engines
IPC: F02M59/00
Filed: 1955-12-09
Abstract: 781,677. Starting direct injection engines. BOSCH GES., R. Dec. 9, 1955 [Dec. 11, 1954], No. 35341/55. Addition to 764,618. Class 7(3) [Also in Group XXVIII] A fuel injection pump is provided with a spring-loaded accumulator piston 10 subjected to the pressure of fuel in a space 42 connected to the delivery pipe 59 of a fuel supply pump 51 and provided with a relief aperture 61 which is throttled at starting speeds, whereby the pressure in space 42 prevents the piston 10 lifting so that excess fuel is provided for starting, and is opened by the delivery pressure of the supply pump 51 at normal running speeds. The aperture 61 is controlled by a ball valve 62 actuated by a spring-loaded control member 64 provided with a throttling aperture 71 and with a number of by-pass grooves 70. At starting speeds the pressure in space 42, acting only upon the ball valve 62, causes very small lifting of the valve 62 so that the fuel delivered by the pump 51 passes through the throttling orifice 71 and the high pressure maintained in space 42 prevents piston 10 lifting. At normal running the higher pressure developed initially by the pump 51 moves ball valve 62 sufficiently to allow the pressure to act on the head of member 64 and move it further to the right to bring the grooves 70 into communication with the exhaust ports 72 leading to the fuel tank. The pressure in space 42 is thereby reduced permitting the piston 10 to lift and displace the fuel in chamber 42 through aperture 61 when the injection piston 5 rises, thus reducing the delivery per stroke of the piston 5.

A gas-liquid contact column comprises a series of horizontal contact platforms arranged one above the other in a column down which liquid is passing wherein each platform is sub-divided into sector-shaped or annular sections in such a way that imperforate section is followed by a gas permeable section through which a gas is passing upwardly and which is followed in turn by an open section allowing free passage of liquid on to the platform below, if desired a weir being provided at the free edge of the imperforate section to determine the level of liquid on the section and a downwardly projecting extension of the weir depends into liquid on a lower platform. As shown in Fig. 2 which is an expanded drawing of a portion of a column comprising three platforms A, B and C, each platform having sector-shaped imperforate sections a and e, perforate sector-shaped sections b and f and open sector-shaped sections b<SP>1</SP> and f<SP>1</SP>. Weirs c and g are provided in sections band f, downward extensions of the weirs providing a retaining wall d for liquid on the imperforate sections a and e of platform B and depending into liquid on the platform C and forming a gas seal preventing gas by-passing portions of the column.

In a further modification the various sections are annular, the liquid flowing from the periphery of the platform towards the middle of the platform on one platform and vice versa on the succeeding platform.

Abstract: 522,458. Cathode-ray tubes. LUBSZYNSKI, H. G. Dec. 10, 1938, No. 36052. [Class 39 (i)] In a television transmitter an optical image or an electron image corresponding to an optical image is directed to one side of a doublesided mosaic 1, the electrons emitted by the effect of this image being collected by the electrode 5. The other side of the mosaic is scanned to reduce the elements to a datum ; the secondary electrons emitted by the action of the scanning beam are prevented from reaching an accelerating electrode 8 by a strong magnetic field, and in consequence form a space charge in front of the mosaic screen 1. As a result the datum potential of the screen is maintained at the potential of the scanning source and does not rise to the level of the electrode 8. The scanning source may be a photo-sensitive cathode 7 which is scanned by a light spot, produced by a cathode ray beam deflected over a fluorescent screen ; the photo-electrons are accelerated by the electrode 8. A guard electrode 10 at the potential of the source 7 also prevents flow of secondaries from the mosaic to the electrode 8 ; a similar electrode may be interposed between the electrodes 7 and 8. The electrode 5 may be a grid or translucent metal layer in front of the mosaic 1.

The degraded cellulose may be xanthated and regenerated by normal methods. When used in smoking compositions the cellulose may be used alone or may be mixed with moulding agents such as sodium cellulose glycollate, hydroxyethyl cellulose, methyl cellulose and ethyl cellulose, all having specified viscosities. Other materials present may include combustion improvers such as potassium citrate, ash improvers such as calcium carbonate and humidity regulators such as glycerine.

Speed-governing apparatus for a prime mover such as a steam turbo-generator comprises a centrifugal governor 1 of which the movable sleeve 11 is connected to speed and acceleration responsive impulse converters R n , R b , respectively, the converter R n  applying a speed signal to a spring-loaded piston 2 connected by a floating lever 3 with a rod 7 of a control valve 6 of a servomotor 4, and the converter R b  acting in response to a predetermined acceleration to open a valve 10 to apply hydraulic pressure to the lower end of the control valve 6 to cause the latter to be displaced relative to the rod 7 in the direction to cause closure of the prime mover admission or regulator valve which is operated by the servomotor 4. When the acceleration ceases or when the sleeve 11 reaches a stop 12 the valve 10 closes and the pressure below the control valve 6 escapes through openings 16, 17 to allow the valve to return under the influence of a spring 8 to its normal position on the rod 7. The floating lever 3 is connected to the servomotor 4 for follow-up action. The arrangement prevents the actuation of tripping mechanism on sudden drop in load on the prime mover. In a modification, the displacement of the control valve 6 relative to the rod 7 is effected by a loading spring on release of pressure by an acceleration-responsive valve.
