Abstract: The fuel injectors are supplied with fuel by pump (18) driven by the pulley belt (12). The fuel pressure is not enough to operate the valve at the injector nozzle. The extra pressure required to operate the injector is derived from the cams on the camshaft (32) and the sequencing of the injectors comes from an electronic control box (10), whose outputs operate electromagnetic valves. The input to the control box is a signal supplied by an inductive sensor mounted by the flywheel. The sensor sends a stream of pulses to the control box which indicate rotational speed and crankshaft angle and for a 6-cylinder engine, there are three angles at which one or other of a pair of injectors can be operated. The mark-space ratio of the sensor output is different for these three angular positions, so that the absolute crankshaft position is known by the control box at any time. USE/ADVANTAGE - Electronic fuel injection for vehicles. Uses flywheel to give necessary crankshaft speed and position; obviates the need for camshaft sensor.

Abstract: A method for treating a fiber pulp suspension, which comprises transporting the fiber pulp suspension from a maintenance vessel, in which there is atmospheric pressure or at most 1 bar overpressure and in which the pulp suspension is at a temperature which does not exceed 95° C., to a bleaching reactor and introducing the suspension into the bottom part of the reactor, which is at least 10 m high and at the top of which there is an overpressure which exceeds the steam saturation pressure, in which reactor the pulp is subjected to a bleaching treatment under pressure at a reaction temperature exceeding 100° C., in addition to which the pulp suspension, during the transportation from the maintenance vessel to the reactor, is heated to at least reaction temperature. The pulp suspension is pumped to a mixer with the aid of a first pump which provides 1.5-3 bar overpressure. Low-pressure steam, which is at a pressure of 3-8 bar above atmospheric pressure and a temperature of 135-155° C., is mixed into the pulp suspension in the mixer so that the temperature of the suspension is increased to the desired reaction temperature. After that, the pressure is increased still further with the aid of a second pump 18 after the mixer, so that the heated and pressurized pulp suspension can be pumped into the bottom part of the reactor. The invention also relates to equipment for implementing the method.

Abstract: A unique, highly effective, electric dry shaver incorporating rotary cutting blades for use by women to effectively, conveniently, and comfortably shave both legs and underarms is achieved by incorporating a blade guard removably mountable to the electric shaver for partially blocking the rotary cutting blades while also smoothing and/or stretching the soft underarm skin. By employing the rotary cutting blade guard of the present invention, the soft, pliable skin typically found in underarms is comfortably smoothed, spread, and/or stretched to prevent any cutting or pinching of the skin by the blades. As a result, a close, comfortable shave is attained, with all of the hair being completed cut, regardless of the contours of the skin surface or the soft, pliable nature of the skin. Furthermore, when the legs are to be shaven, the blade guard is removed thereby fully exposing the side walls of the slotted outer cutter so it can be used in its entirety.
