Patent SE-7901319-L (SE)
Inventor: BASSOLI C
IPC: F02M41/14
Filed: 1979-02-14
Abstract: A distributor-type fuel injector pump for an internal combustion engine has a rotary distributor member formed with two outlet passages communicating with a pump chamber and arranged to distribute fuel intermittently to successive fuel delivery apertures leading to respective engine cylinders, so that in each revolution of the distributor the pump delivers to each cylinder a principal fuel injection at the end of the compression stroke, preceded by a pre-injection. Automatic timing control means advance the delivery stroke of the pump automatically in response to engine speed increase, and the angle between the outlets of the two outlet passages is such that as the engine speed varies the ratio of the fuel pre-injected to that of the principal injection into each cylinder varies according to a rule predetermined in relation to the type of engine (i.e. precombustion chamber or direct injection type).

Abstract: An rf oscillator comprising an electric circuit and an optical leg is used to measure physical variables capable of changing the length of the optical leg. In the circuitry, a beam of amplitude modulated radiation returning from the optical leg is converted to an electric signal, amplified, and used to modulate the drive of an LED which emits a beam of optical radiation. The beam is delivered to and returned from a reflective surface at the end of the optical path by waveguide means, phase shifts in the beam due to actual or effective changes in the pathlength of the optical leg are converted to corresponding shifts in the frequency of the oscillator. Details are given of using this in a fluid barometer, differential pressure sensor, fluid velocimeter, Pitot tube, shift position locator and in temperature sensors. Fig. 2 shows the barometer, where the modulated beam from LED 16 is passed to the reflective surface 60 of liquid 54 by fibre optic waveguide 44, the returning beam being separated by beam-splitter 26 and passed to detector 22 which modulates the LED via amplifier 20; the resonant frequency varies with the length of path 58 and hence with atmospheric pressure. <IMAGE>

Abstract: In a vibrator unit for driving a penetrating element (16), such as a pile tube, two weights (10A, 10B) of equal sizes are put in synchronous motion in opposite directions each along one of two uniform and mutually parallel or bits located on opposite sides of and at equal distances from an axis (2) coinciding with the longitudinal axis of the element (16) in such manner that the weights (10A, 10B) always simultaneously cross a plane of symmetry of the two orbits coinciding with said axis (2) and between these crossings are on opposite sides of said plane of symmetry. The speed of weights (10A, 10B) cyclically varies during each revolution and reaches a maximum at one crossing of the weights through said plane of symmetry, whereby the penetrating element (16) will be subjected to unidirectional axial thrusts and at the same time to momentarily increased torques causing the element to rotate stepwise in a predetermined direction. Each weight (10) is pivoted to a fixed crankshaft (9) and is longitudinally slidable in a bearing (11) mounted by trunnions (12) in a flywheel (3). <IMAGE>

Abstract: The invention relates to a method and means for removing water from a web in a press of a papermaking machine. The web to be dried is passed between press felts through a press nip formed between press rolls. A resilient mat or the like, which is in contact with one of the press felts, is also passed through the press nip. In order to produce a hydraulic counterpressure at the nip, a wire is passed between the resilient mat and one of the press rolls and water is sprayed on the wire immediately before the press nip for producing a water cushion in the section of the wire lying between the press roll and the resilient mat. The wire is in this case formed so that water cannot move in the longitudinal or vertical direction of the wire.
