Abstract: A valve suitable for a vehicle suspension unit - in order to achieve slow quiet discharges, quick charges and long isolation periods, when required, such as would be desirable in cars having variable suspension height - a restricted discharge conduit (11, 6) is automatically bypassed in one direction only by a wider conduit (15, 9), according to the sense of the pressure difference. 
     The long isolation periods are desirable since, if a vehicle is left parked in public for two weeks, it would be unsightly if its suspension collapsed (even though operation would immediately pump it up again). Accordingly the passage (11) participating in said restricted discharge is also used to apply the high pressure of the suspension unit to force a valve flap (8) tight against its seating (21). Only one solonoid actuation is needed, ie to initiate the slow quiet total discharge or softening of the suspension.

Abstract: A temperature monitoring system includes a linear array of six pyroelectric sensors (22) mounted in a block (18). A through hole (20) is provided in the block (18) for each sensor (22). A bore in the block having an axis which intersects the axis of each through hole (20) accommodates a rotary shaft (26). The shaft (26) is provided with a diametrically extending bore (28) for each through hole (20). Thus rotation of the shaft (26) alternately exposes each sensor (18) to the shaft (26) itself and to an object in the line of sight of each sensor(22) as defined by its corresponding throughhole (20).The output signal from each sensor (22) is differentiated and used to provide a temperature measurement. The output signal is corrected for any drift in the temperature of the shaft (26) or block (18). This is effected by periodically bringing a heated calibration head (36) operating at a known temperature into the line of sight of each sensor (22).

Abstract: Most gaseous ion lasers run with continuous drive and operate under steady state thermal conditions. They cannot be driven according to the needs of the application, and their kilowatts of waste heat must be removed from the working environment. 
     Michael R. Smith invented a gas laser tube (U.S. 3,626,325), which operates in the repetitively-pulsed mode, and permits "bursts" of pulses that deliver high power from a low average drive level. It features a radiatively cooled discharge tube which moderates one of the debilitating effects of sudden changes in tube drive. The other debilitating effects, not addressed by Smith, are corrected by the present invention. 
     A fast transient effect, ion loss to the wall of the bore, is dealt with by pre-saturating the wall during novel bore-conditioning pulses applied at startup under the control of microcomputer MC. Denser gas is provided during this step, otherwise only small bore tubes could be saturated. Other improvements provide means for overcoming the transient effect of discharge gas pumping. And a thermal thinning of the column gas that remained in the Smith design is avoided by means of a novel gas density regulation. 
     The result is a switched, dynamically operating gas laser, whose drive can follow the peak needs of the application while its waste heat is averaged to a low output level acceptable in the working environment.

Abstract: A shaking table for ore-dressing, having riffles (50) on its deck (10), has circular orbital motion imposed on it to cause the riffles to oscillate, and for a standing wave (71) to be created between the riffles. The continued circular motion acting on the standing waves causes sharp separation of the material fractions which are discharged continuously from the deck. 
     The slope of the deck (10) and riffles (50) and the configuration of the riffles are critical. The slope of the deck is set empirically by estimating the approximate slope appropriate to the parameters of the material being treated and of the motion imparted to the deck; and the final adjustment is made by slewing the deck in its own plane to obtain an optimum result. 
     For a frusto-conical deck (69), the adjustment is made on a flat deck and the frusto-conical deck is constructed accordingly. 
     The deck may have rectilinear or curvilinear motion imparted to it, superimposed upon the circular motion.

Abstract: In a valve device for fluids under pressure, having a diaphragm which is subject to the pressure of the fluid under pressure, it is normal to influence at least one operating parameter by the magnitude of the effective area of the diaphragm which is subjected to the pressure. In this case, the magnitude of the effective area is defined by the dimensions of a support on the housing side. To change the magnitude of the effective area, it is known for the housing part carrying the support on the housing side to be replaced. A wide range of adjustment possibilities for the magnitude of the effective area necessitate a correspondingly wide range of housing parts, with a correspondingly high cost. This cost is reduced by means of the invention. The invention proposes to provide at least one housing insert (1) to support the effective area (12, 15) of the diaphragm (2). <IMAGE>

Abstract: In a thin-film magnetic head having a magnetic core (upper magnetic layer), in the electromagnetic conversion section (H3), which are composed of an upper first magnetic film (111), inorganic insulating film and an upper second magnetic film (131), said upper first magnetic film is used as a second wiring (111a) for electrical continuity between the coil (81) and input/output terminal (151a). 
     The upper fist magnetic film is connected to the center of the coil which is of a single-layer structure. The first upper magnetic film is made of a same material as the coil and formed simultaneously with the latter. In the region in which an input/output terminal backing is formed, the upper first magnetic film is removed. The input/output terminal backing is formed in a region where the upper first magnetic film (second wiring) is removed. Thus, the electrical continuity is established between the input/output terminal and the center of the coil. 
     Also, the outer circumference of the coil is connected to the upper first magnetic film. Consequently, the upper first magnetic film is formed on the first wiring, and it is removed in a region where the input/output terminal backing is formed, and the input/output terminal backing is formed in a region where the upper first magnetic film is removed, thereby providing an electrical continuity between the outer circum­ference of the coil and the input/output terminal. 
     Also, the utilization of th upper first magnetic film as   second wiring is applicable to a thin-film magnetic head having a coil of a multi-layer structure.
