IPC: F02B1/00
Abstract: 125,147. Higginson, J., and Arundel, H. June 16, 1916. Vacuum apparatus. - In liquid-fuel supply apparatus for internal - combustion engines, wherein the fuel is raised by section to an intermediate tank whence it is discharged by gravity to the carburettor, a vacuum pump is employed as the source of suction and positively actuated valves are fitted to the suction and atmospheric connexions of the intermediate tank and so actuated from the pump shaft, that one is opened as the other is closed. Suction in the intermediate vessel b is exerted through a pipe c by a pump a, and the vessel is open to atmosphere through a pipe i. The pipes c, i are fitted with valves b', j, respectively, which are actuated by projecting-pieces f, m on the gear wheel g. The valve j is returned to its open, and the valve b' to its closed position, by springs n, o. As modifications, the valves b<1>, j may be of the rotary type and situated as shown at h on the axis of the wheel g. A float-actuated valve p cuts off the suction when the fuel, entering at d, has risen sufficiently in the tank b.

Abstract: 643,642. Metal-vapour lamps. BRITISH THOMSON-HOUSTON CO., Ltd., and RUFF, H. R. May 18, 1945, No. 12573. [Class 39 (i)] In a low pressure fluorescent discharge lamp 1 with a filling of argon and mercury vapour starting is facilitated by a strip 4 of conducting material extending along the envelope and terminating near the electrodes 2 and 3, and in addition these electrodes are so designed than an ionizing discharge occurs across their ends during the starting period. The conducting path is earthed and may consist of a strip of metal or of metal particles sprayed on to a roughened strip on the glass or sprayed through a mask on to the surface of the envelope previously heated above 300‹ C. The electrodes are coiled-coil tungsten filament with emissive coating and may be provided in known manner with auxiliary electrodes. The circuit comprises a stabilizing choke 7 in one of the leads to the primary winding of an autotransformer 6 from source 5, with secondary windings 8 and 9 to supply preheating current to the electrodes. In another arrangement the autotransformer provides from its secondary winding a voltage higher than that applied to the primary and in a third the transformer is so designed to dispense with the choke.

Title: Ink jet printers

Filed: 1976-03-31
Abstract: 1487048 Ink jet printers INTERNATIONAL BUSINESS MACHINES CORP 31 March 1976 [10 June 1975] 12969/76 Heading G4H An ink jet printer includes plural font storage means. As disclosed, ink drop charging is controlled (with correction for inter-drop induction and wake effects) from a character generator fed from a selected one of three font ROMs, which store a run length coding of the characters plus line weight (number of drops "wide" parts of the characters are) plus character heights plus specification of repeated (identical) scans. The first ROM is hard-wired and relates to a first font and part of a second font. The other two ROMs are chips pluggable into receptacles and relate to the rest of the second font and a third font respectively. In one mode of operation, the ROMs are interrogated in turn initially to read out codes identifying the fonts (style and pitch) so that during subsequent printing the appropriate one can be addressed to obtain the font required. In another mode of operation, interrogation is performed on change of font during printing until the required font is located. When, during printing, the required character is of the second font but in the first ROM (see above), a bit from the second ROM indicates this and causes accessing of the first ROM.

Abstract: The tongue plate comprises two diametrically opposed tongue parts (4, 5), each of which has a hook (40, 50) which engages into the hook mouth (53, 43) of the other hook (50, 40) when the tongue plate is assembled. The assembled tongue plate then forms a two-sided figure which is delimited by identical arcs of a circle. The diagonal, acting as the separating plane, of said two-sided figure is aligned with opposite guiding surfaces (near the ends of the arrows 4, 5) and with inner surfaces, acting against each other, of the hooks (40, 50). The tongue parts (4, 5) can be inserted into grooves (1'', 2'') which are in the form of portions of a circle and belong to structural parts (1, 2), the surfaces (1', 2') of the structural parts (1, 2) then being aligned with the said diagonal of the assembled tongue plate. The structural parts (1, 2) can be connected when the hooks (40, 50) of the tongue parts (4, 5) are pushed one into the other, for which purpose the surfaces (1', 2') of the structural parts are laid one upon the other and the structural parts (1, 2) are displaced along these surfaces (1', 2') in the direction of the hooks (40, 50). The connection is released conversely. <IMAGE>
