Patent DE-3836377-A1 (DE)
Title: Laser arrangement consisting of an optically stable resonator having an integrated coupling into an optical waveguide
Inventor: OZYGUS BERND
IPC: G02B6/42
Filed: 1988-10-26
Abstract: Many applications of lasers have been made possible only through the use of optical waveguides for guiding the beam. It is problematic, in particular in the case of high-power lasers, to couple (inject) the radiation into the optical waveguide. Despite complex coupling optics, coupling losses occur which in the case of imprecise adjustment can lead to the destruction of the optical waveguide. These negative effects are avoided when the end face of the optical waveguide is used as beam-removing mirror (beam-sampling mirror). At the same time, high mode discrimination and thus a good beam quality is achieved due to the comparatively small surface of the beam-removing mirror.

Patent DE-3841933-A1 (DE)
IPC: E05D5/02
Filed: 1988-12-13
Abstract: A base plate for fixing a hinge arm of a furniture hinge consists of a bottom plate (2) equipped with bores for the fixing screws (23) and fastenable to a supporting wall and of a cover plate (3) which at least partially engages over the bottom plate (2) and is guided on this so as to be displaceable transversely relative to the hinge arm and which has fixing devices for the hinge arm. Premounted fixing screws (23) are partially screwed into the bores of the bottom plate (2) and pass through the long holes of the cover plate (3). To prevent the bottom and cover plates (2, 3) from being separated inadvertently before assembly, the thread diameter of the fixing screws (23) is larger than the width of the long holes. The pitch of the threads (34) of the fixing screws (23) is at least twice as large as the thickness of the cover plate (3) in the edge region of the long holes, so that a respective flank portion (34') of each thread (34) rests on the upper cant region of one edge of the long holes and thereby keeps the bottom plate (2) up against the cover plate (3).

Title: Device for actuating the shutter blades of a shutter
Inventor: ISHIDA HIROAKI
IPC: G03B9/14
Filed: 1988-12-23
Abstract: Devices are described for actuating two blades of a shutter which is driven by an electric motor which, by means of control signals of an electronic circuit, can be made to rotate in the forward direction or reverse direction. In the case of one embodiment the one shutter blade is provided with inner teeth and the other shutter blade has outer teeth, and a gear driven by the motor meshes both with the teeth of the one blade and with the teeth of the other blade. In another embodiment the gear which meshes with the teeth of the one blade meshes with an intermediate wheel (gear) which has a larger diameter. The intermediate wheel meshes with teeth on the other shutter blade and as a result of the rotation of the intermediate wheel a switch can be actuated. According to a further embodiment an optical sensing device can be provided as contact-free switch, which sensing device has a light barrier whose beam path is interrupted by teeth on one shutter blade which are passed through, so that an electronic circuit can control a control signal for controlling the operating mode of the motor as a function of the output signal of the sensing device. The output signal of the sensing device can also be fed to a display device so that the operating state of the blades can be detected (recognised).

Patent DE-3901349-A1 (DE)
Title: Valve arrangement for several hydraulic consumers
Inventor: SCHMITT MARTIN DIPL ING
IPC: F15B11/16
Filed: 1989-01-18
Abstract: In hydraulically actuated directional control valves for several consumers, the associated pilot-control valves are constructed as pressure-reducing valves with connections to a control-pressure line and a tank line. The tank line can be connected via a pressure-control valve to the tank or to the control-pressure line. The pressure-control valve is actuated by the pressure difference between the pump pressure and the load pressure so that an increased pressure is introduced into the tank line in a controlled manner if there is insufficient supply to the consumer during a falling pressure difference. Thus the pressure level in the pilot-control pressure lines leading to the directional control valve increases so that the directional control valves controlled to the greatest extent are retracted in order to choke the feed to the associated consumers.

Patent DE-3914693-A1 (DE)
Inventor: CHABAS JEAN-ALAIN
IPC: H04N5/38
Filed: 1989-05-03
Abstract: A high precision reference frequency usable for synthesizing the local oscillator frequencies of a transmission or re-transmission station especially in a TV grid network is derived from the received signal which may be heavily attenuated and modulated by a video signal and by the synchronization signals by first converting the received signal into an IF signal and eliminating the video signal in a fixed narrow band filter 22 and then the modulation and synchronization components in a first phase locked loop 24 to produce a signal which after frequency division at 25 is used to control via a second phase locked loop a pilot oscillator 18 producing the required output. The generator is adapted to handle signals corresponding to the French or the European-American standards by suitable frequency conversion twice at 9,21. Local oscillators 12, 12a are incorporated in PLLs responsive to an output of oscillator 18. The second phase locked loop is maintained in lock by a signal on line 240 even when input signal Fi fails. The input signal to first loop 24 may be derived instead from a stable reference oscillator via elements 31-33. <IMAGE>

The body can be suitablye shaped for conveniently holding the tubing (1). In addn. a ring (2) of sealing material is fitted over the extension (8); this ring is pref. thermoplastic. When the structure shown has been assembled it is heated to shrink the tube (1) and soften the seal (2). This prevents ingress of moisture e.g. at the point (4). ADVANTAGE - The plug layout completely prevents the ingress of any liq. (pref. also gasses) along the conductors or their insulating sleeving. The invention also covers a method of producing the plug.

The material in the reactor is held at a pH value of about 5.5 to about 8.5. In a subsequent sepn. stage, the liq. is sepd. into a liq. and biomass on one hand, and decontaminated soil on the other hand; the liquid and biomass are recirculated to the reactor vessel while the decontaminated soil is removed. Gas evolved in the reactor is removed and cleansed in a biofilter.

Title: Closing sequence regulator for double panel door - ensures correct overlap through retardation of upper panel by delay circuit or triggered current
Inventor: FEUCHT FRITZ
IPC: E05F5/12
Filed: 1990-07-04
Abstract: The double door has overlapping edges when closed. The two panels are held in the open position by e.m. catches (5,6) for remote control release. The upper panel section (2) is held in the open position by a retarding control while the lower panel section (1) closes first. After a controlled delay the upper panel is released to fold over the lower panel without jamming. The door sections are closed by springs or hydraulic closing drives (3,4). The delay in releasing the second catch can be via a delay circuit, or by a current derived from a generator driven by the closing action of the first panel (1). Switches which monitor the closed setting of each panel can also be used to provide drive signals. ADVANTAGE - Automatic closing control; no risk of door sections jamming.
