Title: Improvements in revolving work tables of horizontal boring machines and other machine tools
Inventor: SPARKES CURTIS ALBERT
IPC: B23Q1/26
Filed: 1962-07-23
Abstract: 966,736. Machine-tool details. H. W. KEARNS & CO. Ltd. July 23, 1963 [July 23, 1962], No. 28216/62. Heading B3B. A horizontal boring &c. machine comprises a turntable 4 and a fluid-operated jack 8, 9 for lifting the table clear of the cross-table &c. 3 to facilitate its rotation. A pivot 5 on the turntable 4 bears in the cross-table, and a ballbearing 7 is located between the pivot and the piston 8. An actuator cylinder 12 supplies the jack. Clamping means, such as those described in Specification 966,737 for clamping the turntable to the cross-table, are interlocked, as by an abutment-operated electrical switch, with the control for the jack so that the jack cannot be operated if the turntable is clamped. The turntable 4 may be removed from the crosstable, which slides across a saddle 2 movable along the machine-bed 1.

Title: Improvements in gas producers
IPC: C10J3/00
Filed: 1939-10-19
Abstract: 533,540. Gas producers. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and SENIOR, H. V. Oct. 19, 1939, No. 28239. [Class 55 (i)] A gas producer adapted for use on automobiles is arranged to work either on a cross draught or on a vertical draught system, and is readily changed over from one system to the other. When a vertical draught is used, air from an inlet pipe 24 passes to an annular chamber 17 and through openings 18 to below a grate 14, the gases passing from an outlet chamber 20 and pipe 21 through a jacket 22 surrounding and heating the air inlet pipe 24 on the way to an outlet 23. Water from a tank 30 and drip feed 31 is converted in a spiral pipe 31 into steam which is added to the air supply. By operating a valve 27, the air is diverted into a pipe 25 leading to a tuyere 15 which provides a localized fire zone and supplies the air in an horizontal direction, the gases passing out in the manner previously described. The horizontal blast is used mainly for starting purposes, for reviving the fire, but a combination of vertical and horizontal draught may be used. Fig. 6, shows an alternative arrangement whereby air from pipe 24' is supplied as shown to tuyere 15 or by operating handle 32 and moving a hollow slide valve 33, the air passes by pipe 16 to below the grate. In Fig. 9, the tuyere 15 is arranged above the grate, and the horizontal draught has an outlet 47 which leads by a pipe 48 to an outlet pipe 49. Air is admitted through openings 44 and, as shown, passes to the tuyere. By operating sleeve valves 41, 42 which are connected to rod 43, the incoming air passes through opening 46 to below the grate, and the gases from the up draught through the fuel bed pass to an outlet pipe 51 which is now vented through opening 50 in the sleeve valve 42 to the outlet 49. The producer may be worked on the downdraught system when a vertical draught is used.

Title: Internal combustion engine with fuel injection
IPC: F02B23/10
Filed: 1968-06-14
Abstract: 1,204,947. I. C, engine combustion chambers. DAIMLER-BENZ A.G. June 14, 1968 [June 24, 1967], No.28439/68. Heading F1B. In an internal combustion engine in which fuel is injected into a combustion chamber in the direction of an air flow guided along the combustion chamber peripheral wall, the peripheral wall extends in at least a part of the total periphery, with a continuously decreasing radius in the direction of the air flow and in the region before the ignition source merges into the portion of the peripheral wall having the largest radius by means of a wall portion defining a sharp edge and lying in a radial plane. The combustion chamber 2, Fig.1, is formed in the piston 1 and has its peripheral wall 3 decreasing in radial distance for the piston axis 11 in the direction 10 of a circular movement of the air imparted by means provided in the inlet valve 6 or in the inlet passage. At its position of least radius, the peripheral wall 3 forms a sharp edge 4 with a wall portion 5 lying in a radial plane and serving to join this portion to the portion of greatest radius. The turbulence occuring in the region of the sharp edge 4 produces intimate mixing of fuel and air, and the reduction of pressure occuring downstream of the sharp edge brings the mixture into vapour form in front of or below a spark plug or glow plug 9, which is located 15 degrees to 25 degrees downstream of the sharp edge 4. As shown, the fuel jets 12 from the fuel injection nozzle 8 are entrained by the rotating air current before reaching the peripheral wall 3, but in another arrangement, Fig.2 (not shown), the fuel jets impinge against the peripheral wall upstream of the sharp edge (4). The fuel, under the combined effect of its kinetic energy and the action of the rotating air, is detached at the sharp edge (4) from the peripheral wall (3) in the tangetical direction and impinges again on the peripheral wall under the plug (9), which is located at a radial distance from the axis (11) which is greater than that of the sharp edge.
