Patent DE-3013335-A1 (DE)
Title: Acousto-optic modulator - has piezoelectric transducer to modulate light wave in SSB mode
Inventor: RUSSER PETER DR TECHN
IPC: G02F1/335
Filed: 1980-04-05
Abstract: The modulator consists basically of a light wave conductor (1) connected to an electro-acoustic transducer (2) which transforms an electrical signal into acoustic oscillations axing piezo-electric components. These oscillations spread from the transducer (2) along the light conductor (1), in the form of an exponentially damped wave movement, and due to the elongation connected with the longitudinal oscillations and the inner pressure fluctuations, the optical path length is modulated. The effect corresponds to a refractive index modulation by the progressive acoustic wave. A light wave travelling in a positive X direction along the conductor (1) with an angular frequency Wa and wave number Ka is reflected at the acoustic wave with the angular frequency delta W and the wave number delta K. The reflected light wave with the angular frequency Wb and the wave number Kb extends in the nagetive X direction. Hence the frequency relationships Wb equals Wa + delta W, and Kb equals delta K minus Ka approximates to the wave number condition.

Title: Semi-automatic focus control for camera - has initial focus set manually with subsequent fine focus from servo drive connected to detectors
Inventor: KAWABATA TAKASHI
IPC: G03B3/10
Filed: 1980-05-22
Abstract: A semi-automatic focus control for an SLR camera has an initial manual control (2) to set the focus approximately and a servo-controlled fine focus (5) for automatic control. The servo drive only extends for a short range and the combination provides a rapid focus setting with a simple lay-out. Both manual and servo controls move the taking lens axially, but on different threads. The servo-motor (5) has a feedback control from the focus detectors (19) in the base of the camera housing. A selector switch disengages the automatic control for a manual control for special effects, e.g. soft focus pictures and to operate in poor visibility with subsequent flash exposure.

Title: Reclaiming solvent from adsorbent - esp. solvent removed from waste air leaving painting plant, where energy is also reclaimed
Inventor: BLAUDSZUN BERND DIPL ING
IPC: B01D53/04
Filed: 1980-11-07
Abstract: An adsorbant which contains a solvent is desorbed by a stream of hot inert gas. The gas is possibly pre-cooled, and is compressed. The gas is then used to drive an expansion turbine and is thus simultaneously cooled so the solvent vapours condense. The condensate is removed, whereas the inert gas is reheated and re-used in the desorption process. The pref. plant includes two adsorbers which are used alternately to collect solvent from waste air. While one adsorber purifies the air, a stream of hot inert gas is fed through the other and then through a network of heat exchangers and compressors and the turbine, so both the solvent and energy can be reclaimed. Used in reclaiming all types of solvents from air purificn. plant.

Patent DE-3120185-A1 (DE)
Title: Mechanical seal
Inventor: KUPKA DIETER
IPC: F16J15/46
Filed: 1981-05-21
Abstract: An axial mechanical seal for stirrer or pump shafts should be sufficiently tight against even the highest pressures even in a single-acting arrangement and without special sealing fluids but should also be usable in a double-acting arrangement. For this purpose, the non-rotating ring of a pair of rings is designed as a piston displaceable axially in a seal housing under the action of a gaseous or liquid pressure medium. Since this piston does not rotate, sealing it presents no difficulties. Provided on that side of the piston which faces away from the operating pressure is a pressure chamber, which can be formed by an inflatable or expanding body made of flexible materials. <IMAGE>
Patent DE-3126007-A1 (DE)
Title: Fastening device for rock-cutting tools
Inventor: HOLLINGWORTH KEITH JEFFREY
IPC: E21C35/18
Filed: 1981-07-01
Abstract: A rock-cutting tool is provided with an elastic component for securing in a bush of a tool socket. So that the force required for inserting the tool into the tool socket is relatively small and the force required for pulling the tool out is relatively large, the elastic component has projecting parts which in the tool socket assume a position from which they cannot be returned by an extraction force exerted on the cutting tool. An extraction force exerted on the tool causes the projecting parts of the elastic component to be at least partly sheared off or torn off the component area connected to the tool or causes the projecting parts to fold back, so that the tool can be pulled out of the tool socket.

Title: Process for pretreating cellulose-containing textile materials
Inventor: DVORSKY DRAHOMIR DIPL ING
IPC: D06M13/46
Filed: 1981-07-29
Abstract: The invention concerns the use of reactive quaternary ammonium compounds for improving the dyeability of textile materials, in particular textile materials containing cotton fibres. The textile pretreatment process of the invention is based on modifying cellulose fibres with a quaternary ammonium compound prior to dyeing with anionic (anion-active) dyes. It is characterised in that the textile material is treated with an aqueous sodium hydroxide liquor having a concentration from 80 to 350 g/l and then with an aqueous liquor of a quaternary ammonium compound of the general formula <IMAGE>  where     Y is a group <IMAGE>  or <IMAGE> ,   X is an anion of a strong inorganic or organic acid:  n is 1, 2 or 3, and A is a group <IMAGE>  or <IMAGE> where R1 and r3 are each C1-C3-alkyl or C1-C3-hydroxyalkyl, R2 is C1-C3-alkyl or C1-C3-hydroxyalkyl, phenyl or C7-C9-alkylaryl, R4  and R5 are each C1-C6-alkyl, and Z is -CH2- or -O-, and optionally neutralisation and/or subsequent washing with water. Owing to the use of the specific quaternary ammonium compounds, the pretreatment process of the invention makes it possible to achieve a significantly higher dyeability as compared with conventional processes; the subsequent dyeing gives complete coverage of dead and immature fibres.

Title: Circuit for synchronising a transceiver station with the data network of a digital communications system
Inventor: POOCH GERHARD ING GRAD
IPC: H04L25/06
Filed: 1981-08-07
Abstract: The invention relates to a circuit for synchronising a transceiver station with the data network of a digital communications system with a correlation receiver (KE) in the respective receiving device. The reading reliability of the regenerator (RE) which regenerates the received data, affected by the presence of direct current resulting from offset effects and the like, particularly in the case of DC-coupled systems, is intended to be improved. For this purpose, the invention provides, in addition to the correlation receiver (KE) and a regenerating device, a device (OK) for the offset correction (correction of the angle of current flow) of the baseband. The correlation receiver (KE) and the offset correction device (OK) are connected to a processor (R) and via this are indirectly and furthermore directly interconnected. The offset correction device (OK) contains a coder (KO) with an evaluation time controller (BZ). With the measurement of the signal duration difference (change in the angle of current flow), the comparison threshold of the baseband limiter (BG) is corrected in such a way that the duration of the two possible logic states is again approximately identical. <IMAGE>

Title: Galvanic element having metallic gas in the sealing region
Inventor: KUEHL THOMAS DR DIPL ING
IPC: C22C45/00
Filed: 1981-08-25
Abstract: In the case of a galvanic element having a conventionally sealed metal housing, especially of the button-cell type, at least the surface (1) of the housing part (2) which has negative polarity is formed in the sealing region from a metallic glass. Metallic glasses are alloys which are composed of various metals and semimetals which solidify in an amorphous manner like glass when cooled rapidly. As a result of the absence of grain limits and other inhomogeneities on their surface, the hazardous electrolyte tracking, to which the negative cell terminal in particular is subject, is effectively weakened. <IMAGE>
