Title: Word processor, and method of printing a character sequence using this word processor
Inventor: YAMAGUCHI KEIJI
IPC: G09G5/26
Filed: 1986-10-22
Abstract: The invention concerns a word processor which is suitable, for example, for processing Japanese characters, but also for processing characters from other languages. It has a print size (pitch) control to print a sequence of characters with various symbols and/or characters, each of which can also be output enlarged. Using the print size control, it is possible to add a print stop code (SC), recognition of which causes the printing operation to be interrupted, between any two characters or symbols of the character sequence. While the printing operation is interrupted, the printed size of the symbols and/or characters can be redefined or changed, so that the symbols and/or characters following a print stop code (SC) can be printed in the changed size, after printing is resumed. <IMAGE>

Title: Driving device with an electric motor and a reduction gear mechanism
Inventor: WITTENSTEIN MANFRED DIPL ING
IPC: F16H1/46
Filed: 1986-12-05
Abstract: Driving device with an electric motor having an electromagnetically excited rotor and with a reduction gear mechanism. In known driving devices of this kind, the electric motor and the gear mechanism are separate self-contained components with only an operative connection between them. The aim is, starting from this, to achieve a more compact construction. The electric motor and the gear mechanism are built into a common housing (1). The gear mechanism is a two-stage planetary gear mechanism in which the rotor shaft (5) of the electric motor engages directly as the first sun pinion (14) for the planet wheels (12) of the first gear stage. The planet carrier (11) of the first gear stage engages as a second sun pinion (20) in the planet wheels (18) of the second gear stage. The axes of the rotor shaft (5), of the two sun pinions (14, 20) and of the output flange (22) of the driving device lie jointly on the axis A. The driving device is suitable, in particular, for driving the individual wheels of a vehicle since it can be installed directly in the wheel axle to save space. <IMAGE>

Patent DE-3707477-A1 (DE)
Title: Luminaire louvre (spill shield)
Inventor: HOEFLE SIEGFRIED DIPL ING
IPC: F21V11/06
Filed: 1987-03-09
Abstract: In order to avoid disturbing reflections in the outer reflectors (2) of a luminaire louvre due to the reflecting surfaces of the cross vanes (3), provision is made on this upper side for webs (5, 5') which run parallel to the longitudinal axis of the luminaire louvre and are produced from a non-reflecting material. These cross vanes are expediently constructed to be wedge-shaped, tapering off upwardly in the direction of the lamp (1). As seen from the longitudinal central plane of the luminaire louvre, the distance (a) of neighbouring webs (5, 5') increases towards the outside. By means of these webs (5, 5') all light beams which leave the lamp (1) and could impinge on the upper side of the cross vane (3) and from there be reflected onto the outer reflector (2), are blocked out. The loss of light which is thus incurred is very small, as only a relatively small part of the total surface of the cross vane (3) is covered by the narrow webs (5, 5'). <IMAGE>
Patent DE-3707952-A1 (DE)
Title: Breathing mask for long-term operation
Inventor: HOERMANN ERNST DIPL ING
IPC: A61M16/06
Filed: 1987-03-12
Abstract: The invention relates to a breathing mask for long-term positive pressure respiration of patients with pulmonary insufficiency. The breathing mask surrounds mouth and nose. In long-term respiration (about 8 hours a day) sealing of the breathing mask against the face presents problems: the mask must only rest against the face very lightly in order to avoid painful pressure sores; on the other hand, however, it may only have low losses due to leakage. This sealing problem is solved by an inflatable annular bead which is formed such that the particularly sensitive areas of the face, that is bridge of the nose and eyes, are left free. Sealing and tolerability of the breathing mask can be improved by controlling the internal pressure in the sealing bead, so that the air pressure in the bead is slightly higher on inspiration than the air pressure in the mask, while it is lower on expiration, by a special cross-sectional shape of the bead with sealing lips and by application of an intermediate layer of a skin-compatible material.

Patent DE-3726414-A1 (DE)
Title: Covering means which can be rolled up and is intended for containers, in particular for swimming pools, and process for the production thereof
Inventor: MARKE AXEL W
IPC: E04H4/10
Filed: 1987-08-07
Abstract: The covering sheeting (2) exhibits a longitudinal portion (4), on whose longitudinal sides (6) border strips (8) are fastened. Loops (16) are arranged transversely with respect to the width of the covering sheeting (2) and they are connected to the covering sheeting (2) by means of a web seam (20). This design permits a particularly simple production since only the longitudinal portion (4) has to be matched to the size of the container opening which is to be covered, whereas the border strips (8) and the loops (16) are prefabricated as products which are available by the metre and only have to be cut to the corresponding lengths. <IMAGE>
Patent DE-3736452-A1 (DE)
Title: Cam controlled, individual wheel suspension, with constant tracking, camber and long wheel base, on longitudinal and transverse links
Inventor: GEGGERLE SIGMUND DR
IPC: B60G7/00
Filed: 1987-10-28
Abstract: Previously, the simultaneous arrangement of longitudinal and transverse links with relatively large spring displacements has not been possible since they describe an arc during spring compression and rebound and thus the ends moved away from one another. In transverse links of the previous kind, tracking changes always occur, only the changes in camber can be eliminated by using double transverse links. It has not been possible in the past to eliminate the changes in long wheel base at the front and rear axles during spring compression. In order to be able to eliminate the changes in tracking, camber and long wheel base, the links must experience during spring compression a change in length corresponding to the degree of spring compression, which takes place by means of a control cam which influences a pin located on the movable part of the link and thus influences the movable half of the link.

Patent DE-3740992-A1 (DE)
Inventor: WILKES KURT
IPC: B01D29/09
Filed: 1987-12-03
Abstract: A disk drum (3) comprises two end disks connected by tie rods (3, 3) rotatably mounted on the tubular bearing arbor (30). The contaminated water is admitted through the drum arbor (30) and the inlet tank (32) to the carrying by a slot nozzle (33) and flows through the filter belt (4) even when the drum is stationary. The layer of sludge so formed reduces the permeability of the filter belt, and hence the liquid level (23) rises during operation. The driving motor (19) of the drum is switched on by means of a float switch (25) or a time function element and brings a cleaned section of the band into the filtration area, whereupon the liquid level (23) falls and then rises again, and the switching cycle is repeated. Oscillating drivers (41) suspended on the disks of the drum scrape the inside of the filter belt and discharge the sludge removed onto the carrying run (4.1) at the deflection pulley (5.3). The endless filter belt comprises a plaited or woven textile made from fibres, yarns or wires of a flexible, inextensible, incompressible material. The liquid can be cleaned more efficiently if the filter belt is used as a support for a fine filter strip made from a nonwoven or similar.

Title: Inking pad for inking printing types, and method for producing an inking pad
Inventor: MATHEIS GEORG
IPC: B41N7/00
Filed: 1988-03-16
Abstract: The invention relates to an inking pad (1) for inking printing types of stamping apparatuses or printing machines by pressing the printing types against the pressing-on side (S) of the inking pad (1) before the surface to be stamped or printed is reached, the inking pad (1) being mounted on an ink container (7), which is provided with at least one ink outlet aperture (9) and contains the supply (6) of ink, and consisting essentially of microporous and at least partially open-cell foamed material. The invention also relates to a method for producing such an inking pad, in which method at least two layers (2, 3) of hard foam of varying pore size are compacted by heat treatment and the application of pressure and, at the same time or subsequently, are joined together to form a multi-layer inking pad (1). The even surface structure of an inking pad of microporous and at least partially open cell foamed material enhances an even distribution of ink on the stamping plate and thus allows sharp images of the impressions of the printing types to be made on the surface to be stamped or printed (cf. Figure 2). <IMAGE>

Title: Device for cleaning parts of large surface area
Inventor: SCHROEDER MAGDY
IPC: B08B1/04
Filed: 1988-04-14
Abstract: A device for cleaning parts of large surface area, in particular shuttering boards, of concrete, cement and the like, has a sonotrode, that is to say an ultrasonic vibration-generating device (22, 23), which is surrounded by a water pipe (28). To achieve a coupling of the sonotrode to the component (31) to be cleaned, water is fed through the intermediate space (41) between sonotrode and pipe (28) to the intermediate space between the part to be cleaned and the sonotrode. By virtue of the fact that the sonotrode (23) is bathed completely in the water fed in, the entire ultrasonic energy is passed to the water; the water additionally serves also for improving the coupling of sontrode to component and for a binding of the dust generated during cleaning. <IMAGE>
