Title: Verfahren zur steuerung eines einspritzventils
Inventor: BOSS JUERGEN
IPC: F02M51/00
Filed: 2001-06-15
Abstract: Erfindungsgemäss wird ein Verfahren zur Steuerung eines Einspritzventils vorgeschlagen, bei dem das Ansteuersignal (Ua) für den Aktor in Abhängigkeit von der Amplitude und der Dauer gesteuert wird. Der Aktor betätigt dabei mittels eines hydraulischen Kopplers ein Schaltventil, das sich bei niedriger Spannung im ballistischen Betrieb befindet und einen Öffnungsquerschnitt zu einem Zulaufkanal (ZK) freigibt. Mit steigender Ansteuerspannung (Ua) wird der Öffnungsquerschnitt (8) verringert und somit die einzuspritzende Kraftstoffmenge vermehrt. Mit Hilfe der Amplitude und Dauer der Ansteuerspannung (Ua) wird das Schaltventil (5) vom ballistischen Betrieb in den nichtballistischen Betrieb gesteuert. Sowohl die Förderdauer (FD) als auch die Amplitude der Ansteuerspannung (Ua) sind so aufeinander abgestimmt, dass ein oder mehrere Sprünge auftreten können, bei denen von einem Spannungswert (Ua) auf einen anderen Spannungswert (Ua) und von einer Förderdauer auf eine andere Förderdauer (FD) umgeschaltet wird. Das erfindungsgemässe Verfahren findet vorzugsweise bei einer Pumpen-Düsen-Einheit Anwendung, wie es bei einer Direkteinspritzung Verwendung findet. Als Aktor (2) wird bevorzugt ein piezoelektrisches Element verwendet.

Abstract: 1,210,186. Electrophonic musical instruments HAMMOND CORP. 15 July, 1969 [1 Aug., 1968], No. 35552/69. Heading G5J. [Also in Division H3] A moving formant circuit in an electrophonic musical instrument includes a two-transistor band-pass amplifier 9 having a twin T feedback network 28 of which the arm 34, 35, 36 may be progressively cut out by applying a varying control voltage to the FET 40. The band-pass of the amplifier is then progressively changed from a lower to a higher frequency band and the musical tone delivered to the speaker 71 moved from a muted trumpet to a normal trumpet note. A progressive change in the resistance of the FET 40 is accomplished by the keying circuit 50, the transistor 45 and the timing circuit 41, 42, 43. When the transistor 45 is conductive the resistance of the FET 40 is low, but when the transistor 45 is rendered non-conductive in consequence of the closure of the key 60 the voltage at the FET gate rises as shown by the curve 72, the resistance of the FET rises and the band-pass of the amplifier 9 rises from its lower frequency (mute) to its higher frequency (trumpet). The band-pass of the amplifier 9 may be fixed at its higher frequency (trumpet) by closure of a switch 47 to ground the base of the transistor 45. In an alternative circuit (Fig. 2) with a transistor (80) in place of the FET 40, a low frequency oscillator (84) run at a vibrato rate of about 6.5 Hz is provided in place of the grounded connection at switch 47. An LDR (light dependent resistor) may be used as the voltage responsive variable resistor in place of the FET 40 on the transistor (80) of the alternative embodiment. Suitable valves for the various components are given.

Title: High temp and pressure forming appts - for cubic boron nitride and diamond synthesis
Inventor: SIROTA NIKOLAJ NIKOLAJEWITSCH
IPC: B01J3/06
Filed: 1972-07-25
Abstract: Apparatus for producing a high pressure and temp. partic. for the formation of very hard materials diamond and cubic boron nitride, comprising two identical moulds fixed together at their periphery and having on their face circular projections opposite to each other and arranged coaxially to the central indentations or cavities in these faces, which when the moulds are brought together, form a high pressure chamber in which a capsule of a thermally and electrically insulating material, plastic under high pressure, is placed. The projections are so formed that the mutually opposing faces of the moulds exhibit a diametrical saw tooth profile and form concentric retaining compartments as the moulds approach each other, filled by the compression of the capsule material. The spacing between the projections increases progressively in the direction of the periphery of the moulds, and the volume of the compartments is selected in such a way that for a predetermined pressure in the chamber, the pressure of the capsule material on the mould faces decreases progressively in that direction.

Title: Vehicle brake pressure booster valve - has transfer ports of ball valve of increasing section to exclude air
Inventor: NUSSER HERMANN
IPC: B60T13/16
Filed: 1973-07-12
Abstract: Operation of the brake pedal forces a sphere in a yoke against a circular seat to close the outlet valve. At the same time a sphere which closes the inlet valve is lifted from its seat by a plunger directly controlled by the brake pedal which acts upon a pressure plate. High pressure fluid then enters the plunger chamber via the inlet valve and filter and flows through radial drillings and enters the brake master cylinder. The exclusion of air from the hydraulic fluid during the operation of the brakes is achieved by so arranging the transfer ports between the inlet and outlet valves in the first chamber and the inlet and outlet ports in the second chamber so that they increase in area.
