Abstract: A fuel injection pump for internal combustion engines including a cylinder bushing and a mounting flange fastened thereto. The mounting flange mounts the cylinder bushing to a pump housing and includes an adjustment tool engaging portion. This adjustment tool engaging portion extends transversely outwardly from the longitudinal axis of the cylinder bushing to a greater extent than does the location of the bolts which mount the flange to the pump housing. The cylinder bushing is received within the pump housing so that it can be rotated by the adjustment tool within a limited angular region for effecting a basic setting of the fuel quantity supplied by the pump.
Abstract: A fuel supply and metering valve assembly used for injection of fuel to an internal combustion engine includes a control pressure circuit which determines the restoring force on the movable member of the fuel metering valve. The magnitude of the control pressure, and hence the fuel quantity metered out by the valve assembly can be altered by the intermittent actuation of a pressure relief valve which controls a fluid bypass. The duty cycle of the intermittently acting bypass valve is controlled by a regulating device which responds to the indications of measuring transducers, for example an oxygen probe located in the exhaust line of the engine. The transducer signal is superimposed on a sawtooth voltage at the input of a differential amplifier which interacts with other control circuitry so as to vary the length of time during which the electromagnetic bypass valve is energized.
Abstract: A fuel control system to provide an excess fuel quantity during engine acceleration and including manifold pressure actuated control units. The pressure increase in one control unit is delayed by throttling, resulting in net differential control forces tending to increase the fuel supplied to the injection nozzles of the engine injection system while the manifold pressure is rising.

Abstract: A fuel injection system for an internal combustion engine whose air induction tube contains an air flow rate measuring member with non-linear operating characteristics, coupled to a potentiometric transducer which produces the electric command variable for a follower control loop. A control amplifier drives a servomotor which sets the metering slide of a fuel metering valve assembly. The servomotor shaft is coupled to a second potentiometric transducer whose output is compared with the command variable in a bridge circuit connected to the input of the control amplifier. The mechanical link between the servomotor and the fuel metering slide has a non-linearity similar to that of the air flow rate measuring member.

Abstract: A pinch ring for the thread balloon of a spinning machine or twisting machine is substantially a single wire loop forming a spiral or helix. The ring may have overlapping end portions. The degree of overlap and the shape of the overlapping end portions as well as the pitch and the axial clearance between opposite points in the overlapping portions are all critical to the performance of the ring. The pinch ring defined by the invention permits substantially higher production rates without decreasing the rupture strength of the thread and provides a thread with substantially higher strength at standard production speeds.

Abstract: An apparatus for deflecting beams of radiated energy, for example, laser beams, includes a primary deflector capable of deviating the incident beams into a plurality of directions, e.g., under the control of an electric field or by other means. In order to amplify the angular deflection so obtained, a set of essentially parallel diffraction gratings intercepts the deviated beams. The grating parameters are so chosen that each of the incident beams, arriving at slightly different incident angles, is diffracted by at least one grating in the set of diffraction gratings. Since the diffraction angle is substantially larger than the incident angle, an effective amplification of the angular deflection results.The apparatus is adaptable to deflection in a plane and may be used for storing information in holograms.

Abstract: The specification describes an injection system with means for supplying a hot gas stream consisting mostly or totally of combustion air. The hot gas supply device comprises a heating device independent from the internal combustion engine served. The hot gas flow is heated to a temperature of at least 150.degree.C and has a mean flow rate of at least one third of the combustion air required by the internal combustion engine during idling. The hot gas flow is supplied to a zone adjacent to the opening of the injector.
Abstract: A hose or pipe for sprinkling liquids, e.g. water or liquid manure, has oet orifices along its length. These orifices are located in an elastically deformable portion of the hose or pipe. The stress-free shape of the elastic portion is so chosen that when the interior fluid pressure changes, the free aperture of the orifice also changes. By a suitable choice of hose shapes the net flow rate through the orifice may be made independent of the internal fluid pressure.
Abstract: A process of manufacturing briquettes from brown coal includes drying brown coal, which is preferably in fine granular form. The dried brown coal is then heated at a first rate up to a temperature in a range of from about 300.degree. to about 320.degree. C. The brown coal is subsequently heated at a second rate, which is less than the first rate, to a temperature in the range of from about 350.degree. to about 400.degree. C. The brown coal is thereafter pressed into briquettes.
