Patent EP-0286411-A1 (EP)
Inventor: KNAK TORBEN
IPC: B63B23/70
Filed: 1988-04-07
Abstract: A safety clutch includes a first tubular part (1), a second tubular part (13) and a plurality of locking members (5) co-operating with said parts in such a manner as to establish therebetween a releasable connection. 
     The locking members (5) have inclined abutting surfaces (11) orientated so that the engagement between said surfaces and a corresponding abutting surface (12) on the second part (13) exerts a radially outwardly force on the locking members (5). Said force is trans­mitted over axially parallel locking surfaces (16) to a corresponding locking surface (19) on an encircling locking ring (18) which in the locked position of the clutch mechanically prevents the locking members (5) from disengaging the second part (13). The releasing force of the clutch is thus closely associated with the frictional force existing between the locking surfaces (16 and 19) and which in practice may have any desired value. 
     A spring-biassed and axially displaceable release ring (25) for releasing the clutch is arranged around the locking ring (18). Dependent upon the allowed axial displacement of the release ring (25) it is obtained that the force transmitted to the locking ring is either equal to the force of the inserted spring or is directly equal to the force exerted on the release ring (25). 
     This opens up the prospect of obtaining in a simple manner a safe release of the clutch in the off-­load case as well as in the on-load case.

Abstract: A novel devitrifying frit is disclosed which has a coefficient of expansion essentially the same as that of silicon. The subject frits have a high softening temperature and excellent reheat stability which make them useful in ink formulations for forming dielectric layers in multilayer circuitry. The frits are also suitable for use as a substrate material for direct mounting of silicon chips or for use in thick film via-fill inks. The frits are zinc-barium-aluminum-silicate glasses containing minor amounts of phosphorus pentoxide, zirconium silicate and one or both of calcium oxide and magnesium oxide.

Title: Rotary brush tool.
Inventor: KOPPEN DETLEF
IPC: B24D13/10
Filed: 1988-06-05
Abstract: The invention concerns a rotary belt tool for surface working which is much more versatile and effective than known tools but is nevertheless easy to handle, durable, safe, easily maintained, as well as compact and economical. The belt of the tool is designed as an endless, narrow closed ring to which are attached radial external elements such as bristles, teeth, abrasive grain, or burnishing compounds. The belt is attached along its entire periphery to the periphery of the axial surface shell of a single belt carrier which can rotate. The tool, for example for structuring wood, finishing leather, or derusting steel profiles, can be designed as a wire brush, in which the bristles which extends radially outward from the tool axis as the axis of rotation can be attached, for example, in an equally spaced non-rotatable manner to their main bristle axis such that bristles positioned one behind the other in the peripheral direction are laterally offset to one another in the axial direction and the end regions of the bristles for example also in the peripheral direction can be slightly bent, the tips of the bristles can be smooth, and the rate of removal of material can be appreciably varied by changing the direction of rotation of the tool. By varying the lengths of the bristles, for example, over the axial length of the tool, rods of any type of material having a profile cross-section in the longitudinal direction can be surface worked over partial contour regions.

Abstract: Un bandage perméable à la vapeur d'eau (20), tel qu'un bandage chirurgical, est constitué d'un film de matière transparente élastomère mince (24) qui est protégé par une couche de tissu non tissé (32). Le tissu est suffisamment mince, élastique et pelucheux pour absorber les contraintes d'objets abrasifs de manière à protéger le film sous-jacent. Le film et le tissu protecteurs sont suffisamment minces et déformables pour permettre au bandage d'épouser la forme des contours du corps humain. Des adhésifs (26, 34) utilisés dans le bandage pour appliquer le film sur la peau d'une personne et pour fixer le tissu au film sont perméables à la vapeur d'eau. Le film et les adhésifs sont perméables à l'eau et forment un écran de protection efficace pour une blessure contre des infections dues à des bactéries externes.

Abstract: The invention relates to an acoustic delay line (2) for electrical signals. On a monolithic piezo-ceramic substrate (4), two electro-acoustic transducers (6, 8, 8') are mounted as electrode structure. The spacing between the two transducers (6, 8, 8') forms the propagation distance (14). The thickness (d) of the substrate (4) is less than or, at the most, equal to the wavelength or half wavelength of the maximum frequency to be transmitted in the substrate (4) in order to prevent the formation of higher-order modes. The substrate (4) is essentially polarized in parallel with the lines of equal potential which are produced in the substrate (4) when a voltage is applied to the electrode structure. The acoustic wave, which is generated by one of the transducers (6), therefore passes as plate shear wave through the propagation distance (14) between the two transducers (6, 8, 8'). This makes it possible to achieve highly accurate wide-band delay lines for low frequencies which are free of distortion and which, despite long delay times, have small component dimensions. <IMAGE>

Abstract: The locking unit comprises at least two pressure cylinders (20, 25), the pressure pistons of which are connected via piston rods (28) to the mould support (13) and the high-pressure chambers (52) of which are in connection with the low-pressure chambers (50) via overflow channels (42). The overflow channels (42) can be shut off with the aid of valve bodies (43). Arranged in the axis of symmetry (a-a) are a driving cylinder (27, 47b) for closing and opening the injection mould (78) as well as a compensating cylinder (21, 26), in open connection with the low-pressure chambers (50) and connected to the mould support (13). The maximum volumes of low-pressure chambers plus compensating chamber (51) of the compensating cylinder (21, 26) correspond approximately to the maximum volumes of the high-pressure chambers (52). The actual cylinders of the pressure cylinders (20, 25) and of the compensating cylinder (21, 26), formed by steel sleeves (20; 21), are combined into one unit by means of common cylinder covers (22, 12). The driving cylinder (27, 47b) is coaxially surrounded by the steel sleeve (21) of the compensating cylinder (21, 26). The steel sleeves (20) of at least two pressure cylinders (20, 25) are arranged symmetrically with respect to the driving cylinder (27, 47b). As a result, less expensive production is achieved at the same time as a space-saving design of the locking unit.

Abstract: The system and method of the present invention compresses digitized color image signals in real time with an error tolerant compression algorithm utilizing block truncation coding. 
     The system operates upon the digitized color components Y, I and Q derived from scanning an image plane. Memory buffers (100), under control of an address generator (80), receive digitized color components and store them in a 4 x 4 block format. The system further subdivides each Y and I block into four 2 x 2 blocks. An I avg.  signal is derived by averaging 4 neighboring pixels in each 2 x 2 block of the I image plane, and a Q avg.  signal is derived by averaging the 16 pixel values forming the 4 x 4 block of the Q image plane. Signal compression is accomplished by representing the Y and I blocks with two values and a bitmap. Three pipelined signal channels (140, 150, 160) work in parallel to real-time process the signals. The processed signals are encoded by an encoder (170) for transmission over a channel (175). At the channels receiver a decoder (180) decodes the signals and a decompression circuit (190) reconstructs the Y, I and Q signals.
