Patent DE-3721596-A1 (DE)
Inventor: ICHIDA KOJI
IPC: H01J29/48
Filed: 1987-06-30
Abstract: An electron gun arrangement for colour cathode-ray tubes comprising three cathodes KR, KG, KB for emitting electron beams BR, BG BB for red, green and blue, and a main electron lens comprising three front electron lenses Lens1R, Lens1G, Lens1B corresponding to the respective cathodes, and a back electron lens Lens2 common to all three cathodes. Each front electron lens is formed with an aperture smaller than that of the back electron lens and is mounted so as to meet Fraunhofer conditions, in order to reduce aberration. Electron beam transmitting apertures, (for example, h3R, h4R) are formed in the grids G3, G4 forming the front electron lenses, with their respective centre axes parallel to each other, which facilitates manufacture of the electron gun arrangement and enables accurate machining during manufacturing. <IMAGE>

Title: Arrangement of a muscle-powered propulsion system for watercraft, in particular for row-boats of various designs
Inventor: WOELKY OTTO WERNER
IPC: B63H16/08
Filed: 1987-09-04
Abstract: The new rowing system has no oars, as is normal, but is operated by a muscle-powered piston engine; the boat is propelled forwards by the piston sliding backwards while displacing water. The necessary stroke of the piston in the cylinder is increased by the sliding seat carriage, thus increasing the output. This novel rowing system has various boat fittings and hull shapes to match sporting needs. The hulls can be equipped with one or more cylinders, that can be dimensioned according to the acceptable physical efforts. A special form of craft has two hulls, and possesses the stability of a catamaran. Outrigger floats can be added to single-hull boats to stabilise them. The ropes stretched between the steering lever and the foot supports effect the swinging of the rudder, and thus turning to starboard or port, when actuated by the tilting foot supports. An additional version is a propulsion system with driving fins (32), consisting of a complete seat unit (41) and the rowing system, for youthful athletes (see Fig. 7). <IMAGE>

Title: Air-conditioning device, in particular for a motor vehicle
Inventor: DIETZSCH KURT DIPL ING
IPC: F28D1/047
Filed: 1987-11-12
Abstract: Known air-conditioning devices require a large installation space because of the arrangement of the blower and various distribution flaps. By means of the invention, it is proposed to construct the heating element of the air-conditioning device as an annular heating element which is produced without solder. The evaporator can be connected axially in front of the radial running wheel so that the new air-conditioning device can be of very space-saving design. Therefore, without an additional requirement of space, the driver's side and front seat passenger's side can each have a device assigned to them. The new air-conditioning device is used for individual air-conditioning in passenger cars. <IMAGE>

Patent DE-3800137-A1 (DE)
Inventor: BUAN DANILO P
IPC: B41J2/315
Filed: 1988-01-05
Abstract: In a thermal printer, of the kind using an ink ribbon composed of a substrate having a thermally transferable ink coated on one surface thereof, the ribbon is threaded past a print head so as to present the inked surface of a first stretch of the ribbon to the uninked surface of another stretch of the same ribbon, whereby, when the print head is operating, ink is transferred to said uninked surface of said other stretch. A second print head may transfer the remaining ink from the inked side of the first stretch to a substrate (e.g. a mailpiece). As described (Fig 3) fresh ribbon from a spool 46 passes the first head 30 and second head 32 and is then redirected via rolls back to the first head 30 where it is pressed against a platen roller 58 before being respooled at 54. The first head is a selective print head, and the second head transfers all remaining ink to the substrates 70. The ribbon wound on spool 54 serves as a record of the matter printed. The arrangement is stated to be advantageous for printing on uneven substrates 70. <IMAGE>

IPC: B02C18/30
Filed: 1988-07-09
Abstract: The invention relates to a mincing machine having a perforated disc and a vane cutter set, in which stringy and hard material to be cut is separated out. For this purpose, there is provided on the cutter-side side of the perforated disc 6 an in particular spiral-shaped guide groove 11 which proceeds from the cutter hub, extends to an outlet 10 on the outer rim of the perforated disc 6 in the housing 1 and is swept over by the vane cutter set 4a. Provided in the free annular space between the ends arranged at a radial distance from the inside of the housing 1, of the vane cutters 4a, in the region of the outlet 10, is a ring 14 which partially covers the latter and bears against the cutter-side side of the perforated disc 6 so that only hard and stringy components of cut material the size of which corresponds to the passage of the guide groove 11 and to the ring 14, can be conveyed out via the outlet 10. Undesired conveying-out of satisfactory cut material and larger components of cut material which lead to blockages is avoided in this manner. <IMAGE>

Title: Method for carrying out biochemical assays and apparatus for carrying out the method
Inventor: MIURA JUNKICHI
IPC: G01N30/88
Filed: 1988-11-11
Abstract: Catecholamines can be detected with high sensitivity within shortened time spans by introducing a sample containing catecholamines into an adsorption column which is packed with an adsorbent in order to adsorb the catecholamines on the column. Subsequently, a derivatisation reagent is added in order to carry out a labelling before the column treatment. Finally, the catecholamines which have been labelled before the column treatment are analysed by high performance liquid chromatography. Connecting the adsorption column to a separating column of a high performance liquid chromatography apparatus via a liquid path changeover valve makes automated analysis of catecholamines possible.
