Title: Tamping device
IPC: E02D3/068
Filed: 1973-01-12

Patent GB-762684-A (GB)
Title: Improvements in and relating to liquid fuel injection equipment for internal combustion engines
IPC: F02M63/00
Filed: 1954-01-20
Abstract: 762,684. Fuel injection systems. KYLE, D. W. E. and GODWILLMAN, A. Jan. 20, 1955 [Jan. 20, 1954; Aug. 12, 1955], No. 1752/54 and 23455/54. Class 7 (3). The load on a spring-loaded injector valve 5, supplied through a passage 2 with fuel from an injection pump actuated by the cylinder compression pressure, is increased by a hydraulic pressure which increases in correspondence with an increase in the cylinder compression pressure. The valve 5 is loaded by a spring 6 the upper abutment plate of which is provided with an extension 13 in contact through a spring- loaded plunger 12 with a plunger 11 actuated by the fuel pressure in a space 9 connected to the delivery passage 2 through a passage 7 containing a non- return valve 8. The pressure of the fuel delivered by the compression-pressure-operated pump depends on the compression pressure in the engine cylinder and the pressure in the chamber 9, which due to the non-return valve 8 remains substantially constant over each cycle, also varies with the compression pressure. At starting and at low engine speeds, or at reversing, the compression pressure, and hence the pressure set up in chamber 9, is low and is insufficient to move the plunger 11 downwards against the force of the springs 12, 6, so that the valve 5 opens at a comparatively low fuel delivery pressure. During normal running the increased pressure set up in chamber 9 depresses the plunger 11 and increases the load of the spring 6 on the valve 5 so that the valve opens at a higher fuel delivery pressure. When the engine is stopped or its speed reduced to a very low value, the pressure in chamber 9 is reduced by leakage past the stem of plunger 11. The maximum depression of the plunger 11 is limited by engagement of the plunger 12 with a stop 24 and the initial position of the plunger 11 and hence the minimum value of the spring-load on the valve 5, is determined by an adjustable screw 25. The rate of opening of the valve 5 is determined by a dash-pot device 29, 31 interposed between the end of the valve stem and the lower spring abutment plate 28. In a modification the pressure in the chamber 9 is set up by an engine-driven gear wheel pump and in a further modification the pressure in chamber 9 acts upon the end of the piston 11, which end is of conical shape co-operating with a conical seating so arranged that the pressure initially acts upon a small area of the piston and only acts upon the full area after initial movement thereof. Specifications 720,011 and 736,794 are referred to in the 1st Provisional Specification.

Title: Production of flake calcium chloride
IPC: C01F11/30
Filed: 1961-01-17
Abstract: Flake calcium chloride is produced by deposition from a hot aqueous slurry, containing 5 - 20% solid calcium chloride particles, on to <PICT:0904934/III/1> a cooled moving surface, from which it is removed by scraping.  A suitable apparatus is a drum flaker.  The solid particles are fines resulting from the flaking operation. Thus, as shown in the Figure, a 74% aqueous calcium chloride solution is fed to a stirred heated pan 4, the temperature being maintained at 352 DEG  F. Calcium chloride fines (2,400 lbs per hour), containing 78% CaCl2, from the drier 12 and sieve 14, are introduced via feed 7 into the above-mentioned pan, while on the cooled rotating flaker drum 8 a solid layer of CaCl2 is formed.  This solid is scraped off by a knife 9, then conveyed to the drier 12 in which moisture is removed by a hot air stream.  The operating temperatures obtaining in the pan can be between 340 DEG  - 360 DEG F. The total CaCl2 content of the slurry can be from 70 - 78%. The calcium chloride content of the flake can be 70 - 78% but can be raised to 94-96% by more intensified drying.

Abstract: 564,392. Gun mountings for aircraft. PRESTON, J. DE LA P.-B., GREEN, J., and BAIGENT, G. M. Feb. 13, 1943, No. 2430. [Class 92 (i)] A gun mounting for small calibre guns and particularly for those used on aircraft, comprises a pivot member 11, a second pivot member 15 mounted eccentrically thereon, means 17 on pivot member 15 for supporting a gun 18 or guns in such manner as to have a degree of angular movement in both a horizontal and vertical plane, and means for constraining the gunsupporting means 17 to rotate about member 15 in the opposite sense to the rotation of the latter about the pivot member 11. In one construction, Fig. 1, the gun 18 is mounted on an arm 16 which carries the pivot 15 extending through a second arm 13. The latter rotates about pivot 11 extending from a fixed baseplate 10. The pivot 15 carries a sprocket 19 around which passes a chain 20 which is fixed at 21 to the mounting. By this means the sprocket 19 and hence the arm 16 are caused to rotate when the arm 13 is rotated about the pivot 11. In a modification, the chain and sprocket are replaced by a train of gears, one of which is fixed concentrically with pivot 11 and another is fitted to pivot 15, and in another modification links are employed to produce the required movement of the arm 16. According to a further modification, the arm 16 is extended beyond its pivot and has a downward extension engaging in a curved cam track. The arms may be locked in required positions by a pin on the boss 12 of arm 11, the pin being adapted to engage any one of a series of slots or holes in a fixed part of the mounting. The locking means may be operated by a Bowden wire or it may be controlled by a solenoid in circuit with a push button near the control handles. The gun-supporting means may be mounted on a pillar arranged to move vertically in relation to the arm 16 under the influence of a cam, for example, a cam track located between the arms. As shown in plan in Fig. 3, the gun mounting may be hinged at 34 on a base 31 so that it may be stored when not in use, a projection 32 being fitted to the boss 12 to engage with spaced guiding members 33 which prevent the mounting from moving about the hinge except when the projection lies opposite the gap 35 between them. Specification 541,849, [Group XX], is referred to.
