Patent DE-4306754-A1 (DE)
Title: Highly stable high frequency standard - varies hyperfine structure frequency with different light intensities causing regulation of laser light frequency
Inventor: DELFS HANS DIPL PHYS DR
IPC: H03L7/26
Filed: 1993-03-04
Abstract: The standard has a resonance cell (1) in a hollow resonator (2). A frequency modulated microwave oscillator (3,4,5) stimulates the resonator. A laser light source (6) provides pumping light. A regulator circuit regulates the oscillator frequency. This circuit has a photocell (11) which receives the laser beam emitted through the resonance cell and a phase responsive rectifier (13) is timed to the oscillator modulation frequency. Laser light passes through the cell with different intensities. The frequency of the hyperfine structure characteristic is varied through the different intensities and the frequency of the laser light source is adjusted to minimise the light shift effect. ADVANTAGE - Continually keeps light shift effect at minimum.

Title: Power output control method for laser system - using variable time delay between stimulation of laser oscillator and stimulation of laser amplifier
Inventor: MIYAMOTO YASUAKI
IPC: H01S3/097
Filed: 1993-03-26
Abstract: The control system regulates the output power of the laser by controlling the delay between the time slot of the laser oscillator stimulation energy and the time slot of the laser amplifier stimulation energy. The stimulation energy for the laser amplifier and the stimulation energy for the laser oscillator are each held constant. Pref. a TEA-CO2 laser is used for both the laser oscillator and the laser amplifier, the stimulation energy for both provided by a switched current source using solid state components. ADVANTAGE - Accurate and stable control of power output over large range without varying excitation energy, by stabilising laser oscillator and amplifier.

Title: Heated-tool welding device
IPC: B29C65/20
Filed: 1993-05-04
Abstract: A description is given of a heated-tool welding device for the lap-welding of plastic films. Serving for pressing the overlapping films against each other are rotating pressing elements, which bear with surface contact against the plastic films and for this purpose are designed in a band-form or crawler-like manner. As a result, a prolonged pressing time of the plastified film regions and an improved welded joint at an increased throughput rate are achieved.
Patent DE-4317199-A1 (DE)
Title: Process for the UV stimulation of air pollutants and simultaneous catalytic pollutant degradation
Inventor: WOITKOWITZ SIEGFRIED
IPC: B01J19/12
Filed: 1993-05-22
Abstract: In order to decrease the pollution of air particularly with ozone, but also with hydrocarbons in the printing and coating industry (corona units, UV driers, electron-beam driers), a so-called UV catalytic converter was developed. This is a reaction chamber in which pollutants stimulated by UV light convert to less harmful products on a catalytic surface. The UV catalysis is an exhaust air purification process which succeeds with minimum energy input. This is achieved by only the pollutant to be disposed of being energetically stimulated. If, nevertheless, a secondary reaction in a second catalytic reaction chamber is necessary, a relatively small catalytic converter is sufficient, since the majority of the pollutants are already transformed in the UV catalytic converter.
Patent DE-4318019-A1 (DE)
Title: Bendable handpiece for instruments for endoscopic surgery
Inventor: KAUFMANN HELMUT
IPC: A61B17/28
Filed: 1993-05-29
Abstract: The invention offers the advantage that the handpiece for instruments for endoscopic surgery is angled off by at least 60 DEG relative to the longitudinal axis of the instrument, so that handling of the instrument can be optimally adjusted to suit each particular surgery situation. The instrument can be angled off easily and quickly by the surgeon by releasing a locking screw. The special type of pressure transmission from the handle branches to the distal working member does not vary the transmission ratio of pressure exerted and movement on adjustment of the handpiece angle. The design, according to the invention, of the pressure transmitting elements results in a cushioning effect which is desired by the users and which resembles that encountered in normal surgical instruments for tissue-sparing clamping.
Patent DE-4318292-A1 (DE)
Title: Improving gear changing with reconnection of motor vehicle load changing gearbox - using braked engine uptake and braking effect of system elements so increased that engine synchronous rpm for respective gear changing operation is slowly reached.
Inventor: KRUSE GEORG DIPL ING
IPC: F16H61/06
Filed: 1993-06-02
Abstract: The method involves using a torque converter provided in a vehicle gearbox. The engine torque is converted into gearbox driven shaft torque, depending on the gear selected by the driver. The gear changing elements e.g. couplings and brakes are operated by a hydraulic control system. The control pressure (PB) for the gear changing element of the previous gear, is so increased from a lower pressure value (PB2) up to an upper pressure value (PB3), during the braked engine uptake in the time interval (t2 - t3). That the synchronous rpm (NS) for the gear changing operation is reached. ADVANTAGE - Smooth gear changing is effected during reconnection of engine. Improved ride comfort.
Patent DE-4320715-A1 (DE)
Title: Valve for low flow rates in a liquid channel
Inventor: ROSBERG RAINER DIPL ING
IPC: A61M5/175
Filed: 1993-06-23
Abstract: For miniaturised components, valves are necessary which are correspondingly small and need as little electrical energy as possible for their actuation. The novel valve, conceived for low flow rates, is intended to be suitable for a capillary flow chamber and to be precisely controllable. Between a primary channel (13) and a secondary channel (15) there is arranged a valve (valve body 24, valve seat 22), for whose actuation a piezo bending transducer (31) is provided. When the valve is closed, the valve body (24) is pressed against the valve seat (22) by means of spring pressure and is functionally connected to the piezo bending transducer (31) which lifts off the valve body (24) from the valve seat (22) when an electrical voltage is applied. The valve is capable of functioning in all types of liquids. Because of its closed construction it is secure against drying-out of the liquids. It is of compact construction and precise metering of a volume flow into a capillary chamber is possible. As a result of the use of plastics, the valve is secure against environmental influences and against mechanical, chemical and biological effects. <IMAGE>
