Title: Sheet-like polyurethane foam with high slidability and process for the production and use thereof
IPC: A47C31/11
Filed: 1987-06-02
Abstract: A sheet-like polyurethane foam with high slidability or abrasion resistance and extensibility is specified, which can be laminated with other sheet-like structures of textile fibres, natural leather or synthetic leather and is then used for seat coverings. The foam is provided on one side with a plastic strip-grid coating which has an essentially cross-shaped arrangement and has received the desired slidability by smoothing. The application of the strip-grid coating may be carried out, for example, by screen printing. By virtue of the rod-shaped coating, the extensibility of the sheet-like polyurethane foam is completely retained.
Patent DE-3721809-A1 (DE)
Title: Liquid-manure agitator unit
Inventor: SOMMER JOSEF
IPC: B01F15/00
Filed: 1987-07-02
Abstract: Liquid-manure agitator units are intended for thorough agitation and mixing in the liquid-manure pits. It is particularly important that the lowest layers of the liquid-manure pits are also involved. Problems have been caused by parts of the material to be agitated, such as fodder residues, straw, etc., which become entangled on the agitating blade, with the result that the agitating blade becomes clogged and the conveying effect is lost. In the invention, at least one knife, the knife edge of which is arranged at a short distance from the agitating blade, is held on the bearing frame of the agitator unit. The knife cuts the long-fibre constituents conveyed, so that they can no longer become entangled round the agitating blade. The liquid-manure agitator unit is suitable particularly for being driven by the power take-off shaft of a tractor.

Title: Caliper for longitudinal measurements in bores
Inventor: WENZEL HELMUT
IPC: G01B5/18
Filed: 1987-12-21
Abstract: A caliper for measuring inner thread lengths and clearance depths contains a guide housing (1) having a measuring surface (2) at right angles to the caliper longitudinal axis. In the guide housing (1), two axially parallel measuring rods (3, 4) are arranged capable of longitudinal displacement relative to each other and to the guide housing (1). In order to reduce measuring errors and to shorten the measuring time, it is proposed to provide the caliper with a storage facility, in which a fastening device (5, 6) may be brought into engagement with the first measuring rod (3), without thereby influencing the displaceability of the second measuring rod (4), so that differential measurements can be carried out with intermediate storage of the first measured value. <IMAGE>

Title: Lifting device with directional antenna and beam guidance path
Inventor: JACOBS KLAUS DIPL ING
IPC: B23K26/08
Filed: 1988-02-12
Abstract: A carrier vehicle is equipped with a high-energy laser whose transmitting antenna, which guides the laser beam onto a target, can be raised and lowered by means of a lifting device (13). The lifting device is constructed in the form of a pantograph having pantograph struts (15, 16, 17, 18) arranged in pairs. The laser beam is guided, in a manner protected against dust and atmospheric influences, through the inside of the struts (15, 17) of one side of the lifting device (13) by means of fixed deflection mirrors to the directional mirror (11). Supply lines for the transmitting antenna and beam forming devices are guided upwards through the inside of the struts (16, 18) of the other side of the lifting device. On the hinge points of the lifting device scarf mount bearings are used, through which the beam and the supply lines are passed in a coaxial manner. <IMAGE>

Patent DE-3808609-A1 (DE)
Inventor: SCHMELING GEB KRETSCHMER
IPC: C25D11/30
Filed: 1988-03-15
Abstract: To produce corrosion- and wear-resistant protective coatings on magnesium or magnesium alloys by anodic oxidation, use is made of a low-alkali aqueous electrolytic bath which contains
 a) borate or sulphate anions, and
 b) phosphate and fluoride or chloride ions
 and which is adjusted to a pH of 5 to 11, preferably 8 to 9. The applied direct current is interrupted for a short time or partially reversed in order to permit the formation of magnesium phosphate and magnesium fluoride or chloride and, possibly, magnesium aluminate. This produces coatings without or with only very slight inherent coloration which can readily be coloured and which yield a good adhesive base for lacquer coatings or post-treatments.

IPC: A41H43/04
Filed: 1988-06-07
Abstract: An apparatus for bonding flat textile cuts to one another or to cuts made from another material by means of a heat-reactivated, comprises a feed table, a heating and pressing device connected thereto, a following cooling zone, a delivery station for the bonded cuts and a conveying means with a support belt and a cover belt between which the cuts are conveyed in positionally stable manner through the heating and pressing device. In order to reduce the thermal stressing of the belts and more particularly in order to ensure a less frequent replacement of the belts, the conveying means has at least one further conveyor belt located in the vicinity of the cooling zone up to the delivery station and receives the cuts between it and a belt downstream of the heating and pressing device. The later belt can be the support belt, the cover belt of a further belt. <IMAGE>

Inventor: YANAGIMOTO SHIGERU
IPC: B22D11/07
Filed: 1988-09-23
Abstract: In a continuous casting of a hollow ingot (15) by means of a forcedly cooled outer mold (1) and a core (16), gas is introduced (23, 24) around an outer peripheral surface of the core (16) to form an annular gap surrounding an inner peripheral surface of the molten metal (9), and gas pressure is applied on said inner peripheral surface of the molten metal (9). The core (16) may, or may not, be force-cooled. Lubricating oil is separately introduced from both the mould, via slits (6), and the core (16), via a passage (26) and slits or pores. Upper regions of the core (16) may be lined with insulating refractory material to delay solidification at the inner periphery of the molten metal. The lining may be detachable from the core with the initially-solidified metal; the outer mould may be similarly lined. Insulating material may extend over at least part of the melt-contacting surface of the starter block. Embodiments of starter block shaped to provide rapid clearance for cooling water and escaping molten metal are described. <IMAGE>

Title: Threshold guide
Inventor: BIERMAIER JOHANN
IPC: E06B1/70
Filed: 1989-01-18
Abstract: Up until now, due to the manufacturing costs for one reason, conventional threshold guides have been planned only for use by specialists. In particular, handling after use is complex since the threshold guides have to be thoroughly cleaned and stored for adaptation to different masonry-wall thicknesses. In order to provide an improved threshold guide, in particular also for DIY enthusiasts, said guide exhibits a plastic spacer (11) which is designed, in particular, for single use. The spacers for the left-hand side and right-hand side at the doorway are of identical configuration. Adaptation can take place by cutting to length at the spacer or at an angle attachment. The threshold guide is suitable for laying abutment or partition thresholds in a doorway. <IMAGE>

IPC: G11B27/036
Filed: 1989-07-04
Abstract: 2.1. In conventional dictating machines, magnetic tape stores are used for storing the dictation. It is also possible to store the dictation in a semiconductor store. A dictating machine with a semiconductor store the storage capacity of which corresponds to the storage capacity of a magnetic tape store is a relatively expensive device. 2.2. By combining magnetic tape and semiconductor stores in accordance with the invention, the advantages of both families of stores are combined and it is possible to edit a dictation in a surprisingly simple manner. In a first embodiment, the dictation is temporarily stored in the semiconductor store. It is only after the temporarily stored text has been monitored and if necessary edited that it is written into the magnetic tape store. In a second embodiment, the semiconductor store is only used for temporarily storing the new text section. The new text section is read out of the semiconductor store in such a manner that the end of the new text section is gaplessly joined to the original text contained in the magnetic tape store. 2.3. The circuit arrangement according to the invention enables corrections to be carried out in any passages and of any length. By storing the edited dictation in the magnetic tape store, it is possible to continue to use conventional replay machines. <IMAGE>
