Patent DE-3734494-A1 (DE)
Inventor: KARNOWSKI THOMAS ANDREW
IPC: H03K17/972
Filed: 1987-10-12
Abstract: An explosion proof housing (10) includes a control unit having a magnetically actuated keyboard (30) for entering data such as digital codes, presets, and scale factors into the control unit, from outside the housing. The control unit includes an array of magnetic-resistive sensors that are positioned immediately adjacent an inside surface of a cover panel (16) forming part of the housing. An indicia, such as a label (32), defines keys which are aligned with the magnetic-resistive sensors. As a magnetic actuator such as a small permanent magnet, is brought in close proximity with the outside surface of the cover panel (16) and in line with an axial sensing direction of a given magnetic-resistive sensor (as outlined by the indicia), the sensor responds to indicate to the control unit that a function, corresponding number or other data is being entered. The output of the sensor can be used to input data and provide logic level input signals to electronic controls contained within the housing. <IMAGE>

Title: Pressure-pulsation damper for flow media
Inventor: OBERMANN KLAUS
IPC: F17D1/20
Filed: 1987-10-16
Abstract: Damper for the pressure pulsations of flow media conveyed in a pipeline, having at least one hydropneumatic accumulator coupled indirectly to the pipeline with a pressure transmitter (30) in between which transmits the pressure pulsations of the flow medium to a transmission medium via an elastically deformable separating element. The pressure transmitter (30) has a tubular housing (34) which can be inserted into the pipeline carrying the flow medium. An elastically expandable tubular body, for example an elastic hose (32), is arranged in the tubular housing (34) and is held therein in a sealed manner at its ends. The flow medium flows through the tubular body. The intermediate space formed between the inside of the tubular housing (34) and the outside of the elastically expandable tubular body and filled with the transmission medium is connected to the hydropneumatic accumulator via a connecting line. <IMAGE>

Title: Transporting and storage unit
Inventor: MUELLER FRANZ
IPC: B65D19/44
Filed: 1988-03-16
Abstract: The invention describes a transporting and storage unit (1), in particular for packaged dairy products and the like, consisting of a pallet (2) fitted with tracks and of at least one roller container (21) which can be set down on the pallet (2) and interlocked therewith, the interlocking taking place automatically when the roller container (21) is pushed onto the pallet (2). The pallet (2) is fitted with actuating elements (20) which enable the roller container (21) interlocked with the pallet (2) to be disconnected. When a pallet (2) is being loaded with two or four roller containers (21), the interlocking of a first or third pushed-on roller container (21) is cancelled again by the actuating element (20) so that these roller containers (21) can be moved onto their final position and automatically interlock there again. In contrast, the second and fourth roller containers (21) are immediately pushed onto their final place and interlocked there. When the pallet (2) is unloaded, the actuating element (20) has to be used for each roller container (21) in order to effect the release of the respective roller container (21) to be removed. <IMAGE>

Filed: 1988-04-21
Abstract: In a method of producing gas from its liquid phase by vaporisation by means of a liquid, in particular water, in which the liquid is brought into heat exchange with the gas over a predetermined path and in the process the gas is passed through the liquid over several parallel flow paths until the liquid gas is vaporised, provision is made according to the invention for unheated liquid to be used for the heat exchange, which liquid is conducted along an open flow path, over which the liquid is conducted in an alternately rising and falling manner in concentric hollow cylinders at an essentially constant speed, the liquid volume being kept constant and being matched to the flow temperature and the gas throughput in such a way that it eliminates the growth of ice at the flow paths during the heat exchange, and for the gas to be conducted over all flow paths axially through all hollow cylinders of the flow path of the liquid in a rising and falling manner.

Title: Motor vehicle hydraulic brake system with antilock control device
Inventor: LEINEWEBER GUENTER
IPC: B60T8/40
Filed: 1988-10-01
Abstract: In a known motor vehicle hydraulic brake system the booster piston of the hydraulic brake booster, used as pressure modulator in the context of the antilock control, is mechanically rigidly coupled to a servo piston which, on the corresponding application of pressure, can displace the booster piston axially against the effect of the booster piston force, causing a reduction of the braking pressure. In the new motor vehicle hydraulic brake system with antilock control device the servo piston is now coupled to the booster piston only for the transmission of compressive forces and the servo piston, by way of an additional, controllable valve unit forming part of a traction control system (TCS) known per se, can be pressurised from a pressure source according to the control requirements of the said system in such a way that the brake master cylinder can build up pressure independently of the brake pedal. <IMAGE>

Title: Opto-electronic circuit arrangement, especially for length measurement, and method for the operation of an interferometer
Inventor: ULBERS GERD DR
IPC: G01B9/02
Filed: 1988-10-24
Abstract: Opto-electronic circuit arrangement, especially for length measurement, having an interferometer which has a semiconductor laser whose direct current supply is overlaid by an alternating current generated by a first oscillator for altering the wavelength of the light of the laser, and which has a first photodetector which receives the light intensity in the interferometer and emits an electrical output voltage corresponding to this. The modulation of the wavelength of the light is carried out in the range between two mode change points of the laser. The alteration of the wavelength of the light is carried out continuously at a predetermined frequency in the range between two step-change points of the characteristic curve of the laser. This modulation serves in practice as a carrier on which, by changing the values of the interferometer, corresponding useful interferences are overlaid, which can later be separated out by means of phase-sensitive detectors, for which purpose a frequency-modulated reference alternating voltage is generated by means of a voltage-controlled oscillator and, in the presence of stationary interference in the interferometer, simulates identically the interference signal then modulated. By means of the quasi carrier-frequency technology, a transmission free of a d.c. voltage can be carried out, so that the electrical output signal from the interferometer can be freed from d.c. components, which are caused by a fundamental brightness of the interferometer, by means of a simple capacitor. A costly compensation to overcome these d.c. values is ...   Original abstract incomplete. <IMAGE>

Title: Reducing content of nitrogen oxide(s) in coke oven flue gas - by introduction of carbonaceous gas as reducing agent
Inventor: STALHERM DIETER DR
IPC: C10B21/10
Filed: 1989-08-17
Abstract: In reducing the N0x content in flue gas from a range of coking ovens heated with burner and/or mixed gas, with combustion and withdrawal areas of the heating walls, a thermal N0x redn is initiated in the withdrawal areas by addn to the flue gas of a carbonaceous gas, esp a gas contg CH4, eg burner gas or natural gas, as reducing agent. Post-combustion may follow the thermal redn. The thermal N0x redn and/or post-combustion is initiated by introduction of the hydrocarbon gas and/or post-combustion air into the area of the upper reversing positions or the upper horizontal channels, or into the heating flues and/or regions of the regenerators. Introduction may be through horizontal feed pipes in the area of the lid of the oven, and through vertical channels into the withdrawal area, or may be to the foot of the heating flue through channels parallel to the usual channels for introduction of burner gas. At most 10% (0.2-5%) of the amt of heat of the normal heating gas is fed by the hydrocarbon gas introduced for thermal N0x redn and/or post-combustion. The gas needed for thermal N0x redn may be fed through the channels used for feeding burner gas while these are not charged with burner gas. ADVANTAGE - The N0x content of the waste gas is reduced during the operation of the coking ovens, and addn of NH3 gas is avoided. Only little alteration to the plant is needed.
