Abstract: A double-nozzle deluge gun has a pair of nozzles arranged side by side rotatably on a rotatable table and an inter-nozzle control unit for adjusting the inter-nozzle angle measured between two lines obtained by projecting the radiation center lines of the nozzles onto a horizontal plane. Each nozzle has a deflector which is positioned in front of the nozzle during the very short range mode. Each deflector has a side cover which prevents water having passed through the deflector from excessively spreading sideways. The inter-nozzle angle and the water pressure are adjusted in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern in any range. Thus, the double-nozzle deluge gun can be controlled in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern having an appropriate width in any range.

Abstract: A regulable hydraulic dashpot for motor vehicles. It features a shock-absorbing piston (1) and a shock-absorbing cylinder (2). The piston travels into and out of the cylinder on a rod (21). The piston divides the cylinder into two hydraulics compartments (3 & 4). The piston accommodates constrictions that incorporate pressure-sensitive valves (26 & 27). The piston has at least one bypass port. A system of (34) of electromagnetically operated valves reroutes the bypass ports in accordance with whether the dashpot is in the suction state or the compression phase. The object is continuous regulation of the level of shock absorption in a dashpot, rapid response to frequent actuation, an easy-to-establish base line, and a simple design. A slide-valve bolt (13) is associated with the routing (5, 9, 10, & 6) of the bypass during the suction phase. Another slide-valve bolt (14) is associated with its routing (6, 8, and 7) during the compression phase.

Abstract: The invention is a hydraulic dashpot for motor vehicles. It comprises a shock-absorber cylinder and a shock-absorber piston and piston rod. The cylinder accommodates a shock-absorbing fluid. The piston divides the cylinder into two displacement compartments. The piston is connected to the vehicle's body or wheel mass by a neck-and-collar pivot that comprises two components. The first component is a collar. The second is a neck. The neck is preferably rubber and metal. The electric supply lines to one or more sensors and/or one or more variable valves extend outward and are connected to the connecting lines of the processing-and/or-actuating circuit by a plug-and-socket connection. An outer ring has a bore that corresponds with the inside of the cylinder or with the inside of the piston rod for the electric supply lines to extend through. A groove extends at least part-way around the inner surface of the outer ring and accommodates the electric supply lines.

Abstract: A conveyor-belt cylinder has a jacket (1) mounted on a shaft (4) by way of a base (2) and a roller bearing (3) at each end. Each base and bearing is secured by an annular spring (15) and sealed with a labyrinth seal comprising an inner ring (7) and an outer ring (8). The spring is inserted in an annular groove (16) in the shaft. A terminating cap (12) engages the outside of an outward-facing annular flange (10) on the inner seal ring and of another outward-facing annular flange (11) on the outer seal ring. The seal rings constitute stitute a prefabricated assembly in conjunction with the terminating cap. The side of the inner seal ring facing the bearing has an annular recess that accommodates the spring.

The piston is provided with pressure-dependent valves that vary the level of vibration suppression. The vibration-suppression valve system has two vibration-suppressing valves (2) accommodated in alignment in a cylindrical valve housing (1). Each vibration-suppressing valve consists of an axially displaced electromagnetic plunger (5 or 6) that operates in conjunction with at least one outlet (3 or 4) and of at least one pressure-sensitive valve (7 or 8) on stream parallel or in alignment with the plunger.

Abstract: A controlled power supply in which an electric arc is used as a loading element. A single phase ac-to-dc invertor is provided with a matching transformer and a main rectifier and diodes which form the bridge and are connected to the matching transformer. The invertor has a controllable output. The bridge has a diagonal corresponding to an output of the rectifier and electrodes between which an electric arc can be initiated. a circuit for controlling the voltage across the electrodes includes a comparator to compare an actual rectified voltage with a reference value.

Abstract: An arrangement for positioning components such as die or mold plates in shaping machinery, in which a positioning element is inserted into matching bores in the components to be positioned. The positioning element or device is provided with a cylindrical jacket around an axial bore and a continuous through-going slot. An elastic rod is inserted into the axial bore and is subjected to force from at least one end, for the purpose of increasing the thickness of the elastic rod and widening the cylindrical jacket so as to position the component. The components have, thereby, an elastic connection through the elastic rod. The continuous through-running slot provides elasticity by widening in accordance with the force that is applied.

Air can flow through the pipe except when the valve is closed.

Abstract: The invention concerns a device for continuously monitoring the level of at least one gaseous constituent in a mixture of gases. The drawbacks of the known devices are complexity, high power consumption, large size, and, due to their high mass, non-uniform distribution of temperature, entailing imprecise measurement, and inertia, especially at the commencement of operation. These drawbacks are eliminated with a base in the form of a water with at least two electrodes in the form of separated thin coatings and with a temperature sensor separated from the electrodes on one side and with a heater in the form of an electric-resistance heating coating on the other side.

Abstract: A device for filtering hot and dusty gases. The device uses hollow filter components. The components are accommodated in groups in a filter housing (1). Every group communicates with a filtered-gas manifold (21) outside the housing by way of a supply line (9) and a filtered-gas line (11). The supply lines extend individually out of the housing. A valve (13) is accommodated in every supply line. An instrument that determines the state of the filtered gas can also be accommodated in every supply line and/or filtered-gas line.

Abstract: A method and apparatus for fusion of three dimensional data due to an active optical triangulation based vision sensor, and two-dimensional data obtained from an independent TV camera. The two sensors are aligned so that their view volumes are partially overlapped. In the course of a calibration process, a planar target is placed and depressed through the common view volume of the two sensors. The illuminant of vision sensor projects a stripe onto the target. As the stripe is traversed across the target incrementally, it is imaged at every position not only by the camera of the vision sensor, but also by the independent TV camera. The calibration process yields a table which connects the resolution cells of the TV camera to a set of rays whose equations are established in the coordinate measurement system of the three dimensional vision sensor. The calibration table is subsequently used to inter-relate points in either sensory space via their connecting rays.

Abstract: A method of monitoring filter components. The components are hollow and employed for filtering hot and dusty gases. They are accommodated in groups in a housing. Each group communicates through a single supply line with a filtered-gas line. The filtered-gas line conveys the filtered gas away. A sweeper is injected in the form of a gas into each supply line in cycles at higher pressure. The sweeping cycle is recorded. Measurement is carried out in the flow of sweeper and/or of filtered gas. The result of the measurement is compared with the record and an alarm released in the event of a discrepancy.

Abstract: Machinery for discontinuously forwarding material or work past or through discontinuously operating tools, presses for example. Two separated work-holder bars parallel the forwarding stream. The bars move upstream and downstream together subject to a cam. The cam rotates around an axis paralleling the stream. The motion of the cam is transmitted to the bars by a follower and by a transmission. The transmission engages guides that guide the bars. The bars are accordingly discontinuously shifted in at least one direction essentially cross-stream. The follower is mounted on a rocker. The rocker pivots around a pivot secured stationary to the machinery above and more or less paralleling the axis of the cam. The follower is forced by a spring against the circumference of the cam. The transmission is a linkage including a reversing lever. A thruster is articulated to the rocker at a point remote from the pivot. The thruster pivots the reversing lever around another pivot.

Abstract: A consumer electronics apparatus, such as a compact disk player installed and operated in a vehicle, includes resilient elements whose attenuation properties prevent shock and vibrations from being transmitted from a base or housing to a chassis or drive mechanism. The resonance frequency is made adjustable while the housing is closed, by adding or removing supplemental resilient elements. Alternatively, the resilience of individual resilient elements may be adjusted by way of a screw. These adjustments vary an effective resulting isolation resilience and thereby optimize reliability of the components. In another embodiment, a system of permanent magnets or electromagnets may be used together with the main resilient elements.

Abstract: A device for monitoring the hollow filter components employed to filter hot and dusty gases. The components are grouped inside a filter housing (1). The components communicate through supply lines (9) with collectors ( 10). The collectors convey the filtered gas away. The line supplying each group accommodates a lance (15). The lance injects a fluid for sweeping the components clean. A transducer (16) downstream of the filter components detects the pressure of the filtered gas in the line. A change in pressure reveals a malfunction.

Abstract: A burner lance for atomizing a suspension of coal in water by means of an atomizing gas. The lance consists of an inner pipe (1) that the suspension flows through, of an outer pipe (2) radially surrounding the inner pipe and leaving a gap (5) that the atomizing gas flows through, and of a nozzle (10) that narrows in the direction the suspension flows in and communicates with both the inner and the outer pipe. The outer pipe extends along the burner beyond the inner pipe and accommodates a nozzle (10) in that section. The outside diameter of the nozzle equals the inside diameter of the outer pipe. The nozzle tapers at a central angle of 35.degree. to 45.degree. and terminates in a concentric exit (11).
