Title: Improvements in or relating to fuel-injection systems of internal-combustion engines
IPC: F02M61/16
Filed: 1930-09-02
Abstract: 362,368. Regulating. GUINNESS, K. E. L., 10, Cadogan Square, London. Sept. 2, 1930, No. 38987/29. [Class 7 (vi).] In engines in which liquid fuel is supplied from a chamber under pressure to the injection valve, the quantity of fuel supplied at each cycle is maintained constant irrespective of the engine speed, by a governor 21 which adjusts a wedge 19 between the cam 18 and push-rod 12 actuating the valve 14. The wedge is rendered inoperative during the opening of the valve by a second cam 24, Fig. 2, the nose 26 of which pushes the wedge aside during opening. After escaping the nose 26, the wedge is returned by the governor according to the engine speed. If this speed is such that the wedge engages the roller 13 of the push-rod, the closing of the valve is effected by the engagement of the portion 127 of the second cam with the wedge ; but if the wedge does not reach the roller 13, the valve closing is effected by the cam 18. In a modification, two cams engage a wide roller 13, one controlling the opening of the valve only, and the other controlling the closing and adapted to engage the wedge.

The first forming member 28 is connected by draw rods 26, Fig. 2, to a wrist pin 27 on a drive member 24 driven by an eccentric 22. The first ejector member 40 is connected to the wrist pin 27 so as to perform movement in the same direction and stroke length as the first forming member. The ejector member 40 has a front end in the hydraulic chamber 38 and its movement causes a shorter stroke movement of the ejector member 42 provided with the ejector pin 52. The chamber 38 is pressurized at the end of a forming stroke so that the ejector pin 52 is moved immediately the return stroke of the machine commences. After ejection of the workpiece W, Figs. 5 and 6 (not shown), from the die 30 the chamber is exhausted by opening a valve and pressurizing an annular chamber 60, Fig. 3, to cause retraction of the ejector pin. The ejector pin (204) may be tubular, Fig. 9 (not shown), and mounted for sliding movement on a fixed rod (202) for shaping annular workpieces (W).

Abstract: 900,606. Rolling-mill plant. BLAW-KNOX CO. Dec. 5, 1960 [Dec. 22, 1959], No. 41738/60. Class 83 (4). [Also in Groups XIX, XXXVI and XL (b)] In apparatus for sorting sheets in accordance with a characteristic measured before the sheets are sheared from a moving strip, a computer determines in which sheet said characteristic will occur and operates a deflector when the leading edge of the sheet is detected approaching the deflector. Steel strip from a roll C passes a pin-hole detector 11 to a shear 14, while a tachometer 24 produces pulses indicative of its travel. These pulses together with pulses produced by a tachometer 25 are used in conjunction with counts preset on units 45, 46, 47 in accordance with the distance between detector 11 and shear 14, detector 27 and detector 28 respectively to determine the number of complete sheets between detectors 11 and 27, the result being stored in register 39, and the distance of the next potential cut from the detector 11, the result being stored in register 37. When a pin-hole passes detector 11, a pulse is entered in a memory register 40 and is stepped through the register by pulses from tachometer 25 delayed in delay counter 38 to an extent determined by register 37. When the pulse has been stepped on a number of times equal to the number stored in the register 40, the next sheet to arrive at detector 27 will contain a pinhole, and the output from register 40 opens a gate between detectors 27 and 28 so that when the pin-holed sheet arrives at detector 27 the output thereof prepares detector 28 for the sheet. Passage of the sheet past detector 28 causes a pulse to be entered in register 41 which is shifted through the register by pulses from tachometer 30 corresponding to the passage of the sheet along conveyer 15. The pulse leaves register 41 when the pin-holed sheet is about to reach a detector 31 and gates the output of detector 31 to operate the solenoid of the deflector 16. The deflectors 27, 28, 31 are sensitive to the leading edge of the sheets and may be photo-electric or, provided the strip is ferrous, magnetic.
