Abstract: The hydraulic elastic element (3, 6, 7) between the piston (22) and the small-end of connecting rod (10) of the diesel engine acts as a spring owing to the compressibility of oil, and by the action of this element the cylinder volume of the engine can be automatically controlled according to the change of pressure of gas in the cylinder. This property enables the engine to take a higher compression ratio on the condition that the maximum pressure of gas in the cylinder remains within its predetermined limit, and to raise the compression ratio automatically when the load of the engine drops, with the result that the efficiency of the engine will be increased and the performance of the engine under low load will be improved. The rigidity of the above-mentioned hydraulic elastic element can be easily adjusted with the engine in operation for further improvement of the performances of the engine under various loads.

Abstract: A method and apparatus for providing muscle stimulation in the field of Function Electrical Stimulation, particularly electrical stimulation to a muscle employed as a myocardial substitute. The Latissimus Dorsi muscular flap is divided into two parts to coverthe surfaces of the heart and inserted into a thoracic cavity by means of a segmental resection of the second rib. After positioning the muscle in this fashion, first and second stimulating electrodes are threaded into the muscle at desired locations to effect contraction of the muscle around the heart upon application of electrical stimulating pulses between the two electrodes. Stimulating pulses having suitable parameters chosen to effect the desired functional contraction of the muscle are generated in synchrony with natural or stimulated heart contractions. The heart contractions are sensed by suitable sensors which apply a trigger signal to the pulse generator which responds by applying the muscle stimulating pulses to the electrodes after a predetermined time delay. 
     The leads are provided with electrode surface areas which can be varied atthetime of surgical implantation to reflect the desired length of exposed electrode surface area extending through the muscle. Preferably the electrode is fashioned of a length of coiled wire conductor which is covered by an axially movable tubular insulating sheath. At implantation, the tubular insulation sheath may be extended over or retracted the coiled wire conductor to expose a desired length of the conductor.

Abstract: In a roller especially for strip filter presses or machine wire presses which have strip or wire at least partially looped around them, the cross-section of the roller increases at right angles to its longitudinal axis in its edge region with respect to the central region of the roller. This is especially achieved by the roller consisting of a cylindrical core with a ring mounted on each of its edge regions on both sides, the ring, for its part, having a specific cross-section. Such a structural design of a press roller ensures correctly adjustable guidance for the strip or wire on the one hand or, even in the case of the use of two drainage strips, ensures a sealed termination of the two strips in their edge regions. In this way, the pressed material is prevented from emerging at the sides between the strips or wires. If such rings can be moved on the core, the guidance characteristics of rollers can especially be optimised and the sealing characteristics can be improved if two pressing strips are used, since the pressing strips abutting onto one another can be superimposed on one another in their edge region.

Abstract: An actively controlled suspension system has two hydraulic systems for generating damping force against the vibration to be transmitted between a vehicle body and a suspension member (13). One of the hydraulic systems is designed for absorbing relatively high frequency vibration generally input from the suspension member for preventing vibration from the suspension member t=from being transmitted to the vehicle body. The other hydraulic system is active on relatively low frequency of vibration generally input from the vehicle body upon change of attitude of the vehicle body. The other hydraulic system generates a fluid pressure suppressing the attitude change. A pressure control valve (18) and a fluid pressure source (20) may be incorporated in the second hydraulic system so that they may not be active when aforementioned one of the hydraulic system is active.

Abstract: Electrostatic liquid spray coating apparatus in- cluding a frusto-conical rotary atomizing cup of insulative material driven by an air turbine, is provided with a ring-shaped semiconductive charging electrode embedded in the inner surface thereof for contact charging liquid coating material supplied to the rear of the cup as it flows forwardly and outwardly over the rotating cup interior and contacts the electrode prior to atomization at the forward edge of the cup. A generally cylindrical insulative support oody, housing a turbine and its associated air bearing and cup drive shaft, has a reduced diameter intermediate section which provides an annular cavity in which are located liquid coating and solvent valves for controlling the flow of liquid coating and solvent to the cup. The support body is mounted to a rear bracket by several parallel spaced apart insulative columns, one of which is hollow to accommodate a high voltage insulated cable for energizing the charging electrode in the cup via a stationary conductor which terminates in closely spaced proximity to a semiconductive ring on the cup exterior which is electrically connected to the ring-shaped charging electrode on the cup interior via a series of semiconductive pins extending through the wall of the cup between the ring-shaped conductor and charging electrode. A dump valve is mounted on the bracket between the columns. Secured to the forward portion of the support body of an alternate embodiment is a cap having a generally convex contoured outer face into which the rotary atomizer cup is at least partially recessed. The aerodynamic shape of the contour helps to avoid eddys which would tend to draw the spray pattern back toward the apparatus. A ring of jets surrounding the cup provide a projecting and shaping air flow while a repulsion ring embedded in the contoured face helps to further avoid buildup of coating material on the apparatus.

Abstract: Multi-channel safety switching devices require comparators for data to be output to the process so that a signal divergence can be recognised in time and possibly false information items can be kept away from the process. This requires a data-flow-independent checking of the comparators. A release signal (FG1) to be output by the comparator (VG1) when the microcomputer (MR1, MR2) to be monitored is operating correctly is output indirectly via an AND gate (UD1) to output signal converters (AR). A test circuit (TSG1) which has a bistable characteristic is connected to the AND gate (UD1). The test circuit evaluates a key information item (SN1) output by the microcomputer (MR1), which counts as acknowledgement of a predetermined computer routine of the microcomputer (MR1). In dependence on this, an enable code is output for the AND gate (UD1). The abovementioned safety switching devices can be used, in particular, in the case of process controls with safety responsibility, for example in the case of railway signalling. <IMAGE>
