Title: Means of influencing sedimentation on the seabed
Inventor: EICHWEBER GUENTHER
IPC: E02B3/04
Filed: 1984-12-19
Abstract: Means of influencing sedimentation on the seabed similar to artificial sea grass. In order to be able to determine the sedimentation more easily, the upwardly extending flexible elements, or some of them, are coloured in such a way that a different colour impression is obtained in the upper section of the flexible elements than in their lower section. The colour of the lower section recedes in the overall colour impression as sedimentation increases, therefore allowing conclusions to be drawn as to the degree of sedimentation.

Title: Four-stroke piston internal combustion engine, especially for motor vehicles
Inventor: KNIERIEMEN HORST
IPC: F01L7/02
Filed: 1985-11-28
Abstract: In a four-stroke piston internal combustion engine the charge cycle is controlled by a sleeve valve with ports. In this case the sleeve valve extends partially into the combustion chamber. Inside the sleeve valve of hollow construction an arbor is concentrically arranged, which is surrounded by a screw channel. The screw channel serves for the axial delivery of coolant through the annular hollow space forming between the arbor and the inner wall of the sleeve valve. At the same time the screw channel ensures centering of the arbor in relation to the sleeve valve.

Title: Device for determining the initial stressing force of a long anti-fatigue bolt by means of a standing wave
Inventor: STAAKE WALTER
IPC: G01L1/25
Filed: 1985-12-19
Abstract: The invention relates to a device for determining the initial stressing force of a long anti-fatigue bolt 3 having a free bolt section 4 situated between the bolt head 6 and the bolt end 5. The bolt is excited to vibrate by means of a vibration generator 11, and the resultant resonant frequency is displayed via a measuring device 12. In order to be able to detect the case of resonance by simple means, the bolt 3 is extended beyond its head 6 by a resonator section 8, the extended resonator section 8 corresponding to a quarter of the wavelength of the standing fundamental wave which propagates in the case of resonance. The vibration generator acts on the resonator section 8 in order to apply the vibration of the generator, and a measuring device is arranged at the free end of the resonator section in order to tap the resonant frequency (Fig. 1). <IMAGE>

Patent DE-3545264-A1 (DE)
Title: Device for regulating the mixture of gas and combustion air for gas-fired installations
Inventor: NIEDERGESAESS GUSTAV ING GRAD
IPC: F23N5/18
Filed: 1985-12-20
Abstract: In the event of changes in the air differential pressure, a control-pressure regulator of the device actuates a pilot similar to the three-way valve by means of an air diaphragm connected to a differential pressure measuring location in the air line. By letting in or discharging a control medium, the pilot varies the control pressure in a control line to which is connected a balanced pressure regulator arranged in the fuel gas line which varies the mass flow of fuel gas as a function of the control pressure. In addition to the air diaphragm, the control-pressure regulator contains a gas diaphragm connected to a differential pressure measuring location in the fuel gas line. The gas diaphragm acts on the actuating tappet connecting the air diaphragm to the pilot with a differential pressure counter to that of the air diaphragm. In the event of a displacement of the air diaphragm caused by a changed air differential pressure, the gas diaphragm brings about the return movement of the air diaphragm by virtue of a differential-pressure change in the fuel gas line. The pilot of the control-pressure regulator is constructed with a valve member which neutralises reactive effects of the control-medium pressure on the actuating tappet between the air diaphragm and the pilot.

Title: Core ring for the beads of pneumatic tyres
Inventor: MACHMER HORST
IPC: B60C15/04
Filed: 1986-04-19
Abstract: The invention is based on a core ring for the beads of pneumatic tyres, which ring consists of wound wires and one or more wire ends which run out freely on the outer and inner circumference. In order to be able to prevent fractures in the core in the region of the wire ends which run out freely from occurring under high permanent stressing, on the basis of the invention the wire ends are arranged with a part of their cross-section between, or next to, the adjacent turns of the core ring. For this purpose, the wire ends are angled or bent over in such a way that the end sections of the wires lie between the turns of the core ring.

Abstract: An amplifier circuit (12) for an infrared detector (10) of an array of detectors arranged on an LSI structure is manufactured on the structure together with the detector and contains an amplifier stage (14) which is capacitively coupled to the detector (10), and an output stage. An FET switch (16) is provided for selectively coupling the detector to external bias voltage sources, and another FET switch (24) is provided for resetting the amplifier stage after an integration period. In one embodiment, an output stage (28) contains a storage capacitor (30) which is selectively coupled to the amplifier stage by means of an FET switch (32). In another embodiment, the output coding stage (28) contains a dual-gate FET (32) for controlling the voltage across the storage capacitor (30). The dual-gate FET controls a voltage source which periodically pulses and discharges the capacitor. One FET gate is connected to the output of the amplifier stage and the other one is connected to a clock signal. In a further embodiment, an output stage (128) contains a second capacitor (32) having a lower capacitance, to which a charge of the first capacitor (130) is applied for subsequent sampling, which is proportional to the output of the amplifier stage. <IMAGE>

Title: Process for the transport of molten glass from a melt to a processing point
IPC: C03B7/22
Filed: 1986-06-27
Abstract: The invention relates to a process for the transport of a portion of molten glass from a melt through a tap hole in a wall of a glass melting furnace to a processing point by means of an apparatus in which a lance carrying the glass portion at its free end undergoes a first pivoting movement around a first joint with respect to a connecting element, and the connecting element simultaneously undergoes a second pivoting movement around a second joint matched to the first pivoting movement. The first and the second pivoting movements are matched to one another in such a way that the lance is moved into the vicinity of the processing point with its free end tilted upward with respect to the horizontal and only in the final distance to the processing point with its free end tilted downward with respect to the horizontal.

Title: Bearing profile bar for panel-type structural elements
Inventor: CONSTAPEL GERHARD
IPC: E04B7/02
Filed: 1986-11-20
Abstract: In the formation of pyramidal cupolas, the panel-type structural elements covering the latter are supported, for snug bearing, by bearing profile bars which have to have a bearing surface which is adapted to the form of the pyramid. In this arrangement, different bearing profile bars also have to be used for different cupola forms, with the result that universal bearing profile bars for the most common cupola inclinations cannot be used. The novel bearing profile bar is intended always to have the same basic form and to be usable over a large range of angle deviations at the joint of the panel-type structural elements. In order to be able to achieve a multiplicity of inclination angles with the bearing profile bar, said bearing profile bar has a supporting leg, with a foot claw which engages behind the hook strip of a carrying profile bar, as well as a clamping leg which can be pressed against the carrying profile bar by means of retaining screws screwed into said bar. By a corresponding shortening of the clamping leg, a wider inclination range of the panel-type structural elements, which are abutting at angles, can be covered. The novel bearing profile bar can be interposed between a purlin, supporting the panel-type structural elements, and the structural elements themselves and, by adaptable shortening of the clamping leg, it can be adapted, over a considerable angle range, to the inclination position of the panel-type structural elements which are abutting at an angle.
