Title: Improvements in or relating to control mechanism for clutches of internal combustionengines
IPC: F16D25/12
Filed: 1955-09-26
Abstract: 818,058. Operating clutches. FICHTEL & SACHS A.G. Sept. 26, 1955 [Sept.. 29, 1954], No. 27347/55. Class 80 (2). In an internal-combustion engine the clutch 12 is actuated by a servomotor piston 15 in a cylinder 16 through a linkage 14, 15. The cylinder 16 has a duct 17 connectible, under control of a valve 20, to a chamber 24 or to a pipe 27 leading to the engine suction line 25. A chamber containing a flexible diaphragm 22 has a space 21 connected to the suction line 25 by a pipe 26 and a space 23 open to the atmosphere at 36 or connected to the chamber 24 through a spring controlled valve 19. One side of the diaphragm 22 is under the action of an adjustable spring 40 and the other side has a projection 37 extending towards the valve 19. The compression of a spring 33 acting on the valve 19 is adjustable by a screw 34. With the parts in the position shown in Fig. 2, the clutch is engaged. When the gear shift lever is moved to change gear a solenoid winding 30 is energived to move the valve 20 in the manner described in Specification 803,521. Such valve movement disconnects the duct 17 with the space 24 and connects the duct 17 with the pipe 27. Thus the servo piston 15 is drawn to the left, Fig. 1, to disconnect the clutch 12. When the gear shaft is completed the winding 30 is de-energized and the valve 20 returns to the position shown to interconnect the duct 17 and chamber 24. The pressure in the space 24, which is controlled by the valve 19, causes the clutch 12 to partially engage. As more and more fuel is fed to the engine the pressure in the induction pipe 25 and thus in the space 21 increases. This causes flexing of the diaphragm 22 and movement of the projection 37 to the right so that the latter engages the valve 19 and moves it from its seat. The resultant increase in pressure in the chamber 24 increases the clutch engaging pressure. Such clutchengaging pressure will gradually increase until such time as the maximum fuel supply is attained when the clutch will be fully engaged.

Abstract: 1509213 Printers with interchangeable type fonts INTERNATIONAL COMPUTERS Ltd 25 June 1976 [2 July 1975] 27876/75 Heading G4H Apparatus for printing on a record lines of characters in predetermined columnar positions within a line comprises a plurality of print hammers 13, Fig. 1 (not shown) arranged at constant pitch along a print line parallel to the line of characters, means (11) for interchangeably receiving within the apparatus first or second fonts (8) of type of different sizes, the first font (Fig. 3b) requiring a columnar spacing corresponding to the hammer pitch and the second font (Fig. 3e) requiring a spacing different therefrom, and control means (Fig. 2) effective, according to which of the fonts has been provided, to modify the hammer operation to print a line of characters either in a single printing cycle or in at least two printing cycles and which causes shifting means (16-21) to produce a relative shift between the record and the hammers in the direction of the print line by a distance corresponding to the columnar spacing required. As described, a belt printer (e.g. as in Specification 858,410) receives type cassettes containing "normal size" and "small size" (2/3) fonts. Insertion of a cassette 34 or 35, Fig. 2, causes a switch 33 to enable one of gates 30 or 31 which control a multiplexor 28. Data to be printed is routed from a store 22 via multiplexors 23, 28 and buffers 26, 27 (for even and odd hammers) to be compared at 29 with signals 36 indicating the characters in position for printing, a signal 38 from comparator 29 controlling hammers 37. When the normal font is selected, gate 30 allows multiplexor 28 to be switched in synchronism with multiplexor 23 by alternator 25; with the small font, gate 31 ensures that multiplexor 28 is switched only at the end of each print cycle by signals from a control 20 which also operate an electromagnet arrangement 21 (17-19, Fig. 1) which shifts the record. With the small font, the line is broken up into two partial lines (Figs. 3c, 3e) applied respectively to buffers 26 and 27; odd-numbered hammers are actuated when their respective characters are centralized within the left hand two-thirds of the hammer width and evennumbered hammers when their characters are centralized within the right-hand two-thirds. The record is shifted after each partial line (Fig. 3d) so that in the completed line three characters occupy the space of two columns.

Abstract: 373,526. Rectifying alternating current. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Schmidt, A.; 1147, Parkwood Boulevard, Schenectady, New York, U.S.A.) Oct. 14, 1931, No. 28565. Convention date, Oct. 16, 1930. [Class 38 (ii).] The voltage characteristic of grid-regulated mercury arc and like rectifiers is modified by including in the grid circuit an inductance, the value of which is caused to vary so as to vary the phase of the grid potentials with load current by means of saturating windings associated with the load circuit. In the arrangement shown in which the anodes 2, 3 are fed by a winding 7 on the supply transformer 10, the grids 4, 5 are energized by a winding 8 through current limiting resistances 17, 18 and the regulating inductance 13, 14, a condenser 12 being connected as shown. Windings 20, 21 in series with the load circuit are provided on the inductance cores. together with shunt windings 22, 23 acting in opposition to the series windings. The arrangement is such that whereas at no load the cores are partially saturated by the shunt windings, an increase in load up to full load causes desaturation of the cores by the series windings, thus causing such phase shift of the grid potentials as to increase output voltage. On further increase in load current, a return to saturation conditions is brought about by the series windings predominating over the shunt windings and the phase of the grid potentials is shifted back to produce a fall in output voltage.
