Layer (2) is a polyurethane (PU)-based adhesive. Layer (4) is a co- or ter-polymer based on polyamide or pref. propylene or ethylene or EVA, or ionomer, anhydride, maleic anhydride, methacrylic acid, acrylonitrile, synthetic wax or rubber, or other types of functional polymers. The thermoplastic adhesive in (4) is based on PE which becomes tacky in the range 49-89 deg.C (Vicat), or on medium- or high-density PE or (co)-PP (tacky at 90-165 deg.C), or on polyamide, PET or PET gel (tacky at below 260 deg.C).

Title: Industrial water conduction system - has at least one conveying pump driven by controller
Inventor: BINDER JOHANN
IPC: E03B11/00
Filed: 1992-07-11
Abstract: The conduction system supplies water for industrial use via at least one dredging pump (2) driven by a controller (7). The controller (7) is separate from the pump (2). An ultrasound transmitter (8, 9, 10) controls the pump (2) via one branch of the conduction system (4) using ultrasound signals.

Title: Toothed belt drive
Inventor: BARTELT DIETRICH
IPC: F16H7/02
Filed: 1992-08-14

Title: Amplifier with narrow band, IF filter - picks up harmonic heterodyne wave adjacent to required signal
Inventor: MASUYAMA ATSUSHI
IPC: H03G5/24
Filed: 1992-12-30
Abstract: The amplifier has an upper IF filter (6) which picks up the upper side of a heterodyne wave, adjacent a desired signal. The upper filter operates with mean frequency, offset by a preset frequency w.r.t. the upper side of the desired signal. A lower, narrow band IF filter (5) picks up a lower heterodyne wave, adjacent to the desired signal from the received signal.

The output signals of the IF filters are treated by rectifiers (9,10), whose output signals are processed by a differential amplifier (11). A further IF filter (12) displaces its mean frequency to those, at which less heterodyne waves appear. USE/ADVANTAGE - For FM radio and TV receivers. Reduced heterodyne waves for improved audio quality.

Title: Method and device for the optical measurement of objects in a plane
Inventor: KLEEMANN GERHARD DR
IPC: G01B11/10
Filed: 1993-03-13
Abstract: The object of the invention is to specify a method and a device of the type mentioned at the beginning which are also suitable for planar sensors and which can be realised with the aid of simple measures. According to the invention, the object is achieved owing to the fact that the following method steps are executed in a computer:     - determination of a travel length code, - folding of the original brightness function with the aid of a transfer function corresponding to a low-pass filter, and - determination of the point of intersection of the original function and filtered function.   The invention relates to a method and a device for the optical measurement of objects in a plane, in which the object is projected onto a sensor containing light-sensitive pixels, preferably onto a CCD matrix, and in which the optical signal is sequentially fed to a computer after AD conversion. <IMAGE>

Title: Variable-tension rails for locking and unlocking extension/replaceable parts, such as tools, gripper rail sections and the like
Inventor: MICHAEL WOLFGANG DIPL ING
IPC: B21J13/03
Filed: 1993-03-23
Abstract: In the case of a variable-tension rail, the adjustment means moving the tie rod (13) is formed by the cavity of the casing and a piston (4) which divides the cavity into two pressure chambers (5, 6). The piston forms, with the tie rod which is embedded in it, a forcible guide (19, 20, 21, 22, 23) for rotating the tie rod. The clamping means for the clamping movement is composed of an inner conical surface (24) on the piston and wedge-shaped pieces (26) which interact with the said surface (24) and have matching wedge-shaped surfaces (25), the wedge-shaped pieces being moved radially when pressure is exerted on the pressure chamber (5), thus pulling back the tie rod in the direction of a clamping movement. This means, in particular, that increased force is exerted on the tie rod. <IMAGE>

Title: Interior partition for boxes
Inventor: SCHLICHTING EDITH
IPC: B65D5/49
Filed: 1993-10-21
Abstract: Small items drop out of the compartments when a box is turned upside down. Example: A box of games which has to be turned upside down to read the text on the bottom. In a simple and cost-saving manner, the novel interior partition prevents small items from dropping out of the compartments. The interior partition is folded several times in parallel in one direction from a strip of card. The height of the interior partition (1) is lower than the inner height of the box (2). The intermediate walls (3) are trapezoidal in shape and project over the compartments at the top. The sloping sides (4) do not touch at the bottom and are longer than the inner height of the box (2). When the box is turned upside down, the trapezoidal intermediate walls (3) are pressed against the lid (5) of the box. The interior partition is suitable for boxes with a lid which contain sorted small items. By pushing the partition together or pulling it apart, the height of the intermediate walls is changed. One design can be adapted to different box sizes without recalculating the dimensions. <IMAGE>

Title: Quantitative evaluation of scattering properties of surface defects
Inventor: TZSCHOPPE WOLFGANG
IPC: G01N21/47
Filed: 1994-01-14
Abstract: The surface is scanned in two dimensions using a laser spot of defined size and intensity distribution. The scan raster point distance is smaller than the spot dia. Regularly reflected laser light is absorbed by a light trap. An optical scattered light collection system with large aperture feeds the light scattered at a surface or vol. defect to a receiver. The scattered light measurement values (4) for each defect produced by the receiver are summed at least one-dimensionally to yield a scattered light measurement value sum, depending on defined threshold conditions allowing only measurement values corresp. to a defect typical signal characteristic, and with a sufficient number of summands, to be summed.
