Filed: 1995-03-03
Abstract: The invention concerns an appts. for controlling the radiation of a laser unit incorporating a radiation transfer system (10) with a light wave guide (11) and machining/processing optics (14). The appts. includes a measuring system (16) for laser light extracted from an optically transparent component (15), a signal evaluating unit (17), a generator (18) of reference values proportional to the laser output power and a control unit (19).  The appts. is characterised by the following facts: (a) an optically transparent component (15) of the machining/processing optics (14) is connected to the measuring system (16) for determn. of the scatter radiation; and (b) the control system (19) can switch off the radiation (12') for a predetermined difference from the reference value for the laser output power.  A switch-off of the radiation (12') by the control unit (19) with a differentiation element can take place dependent on the rate of change of the measured value of the scatter radiation. This operation is performed by a mechanical beam switch interrupting the beam (12). The optics (14) have a modular construction. The modules (27,27') are provided electrically controllable contact elements (28).

Title: Centrifugal motor rotor guide paths
Inventor: GRUHSMANN MANFRED ING
IPC: F03G3/00
Filed: 1995-08-08
Abstract: The rotor (1) has two or more entrainer shafts (6) fitted out with freely movable centrifugal weights (7) standing radial to the centre of the drive shaft (3). Each weight consists of a guiding axis (8) with two holes for the entrainer shafts (6) plus a cylindrical roller bearing (9) pressed onto the guide axis (8). The circular or elliptical guide path of the rotor in right-hand rotation lies radially nearer the rotation centre of the shaft (3) between points (11) and (12) than between points (12 and 11). The rotor is joined to the drive shaft in a straight line, or again the rotor or rotors are angularly offset round the rotor drive shaft. Thus two synchronous and opposed rotors pass through points (11 and 12) at the same time during left-hand rotation. As shown therefore, the first elliptical path starts from point (11) and ends at point (12), this in turn also forming the start of the ellipse ending at point (11).

IPC: C08J9/14
Filed: 1995-08-10
Abstract: Described is an NCO-group-containing polyurethane prepolymer madefrom polyisocanyates and polyols derived from natural oils. The invention is characterized in that the polyol is obtained by transesterification in the presence of basic lithium compounds. Together with a tertiary amine used to accelerate the moisture curing, the storage stability is thus increased considerably. Up to 4.0 mmol of the lithium compound is used per kilogram of polyol, and 0.1 to 2.0 % by wt. of the amine, relative to the total weight of the composition, is used as the accelerator. The polyurethane prepolymer is suitable not only for the production of adhesives but also for the production of foamed materials, in particular those dispensed from throw-away pressure vessels.

Title: Synthetic aperture radar for object identification by aircraft or space vehicle
Inventor: HOUNAM DAVID DR
IPC: G01S7/40
Filed: 1996-05-22
Abstract: The synthetic aperture radar is calibrated using a transponder. The transponder receives signal pulses emitted from the SAR and converts them to intermediate frequencies. These intermediate frequencies trigger a code generator (12) which phase modulates the IF signal, which is then converted back up to a frequency which is the same or different from that received, amplified and transmitted.  This enables the transponder to be identified. The SAR processes the signals from the transponder to provide a display on which the transponder is clearly visible, or alternatively so that it is defocussed.
