Title: Stepladder with tool shelf
Inventor: ACHENBACH DIETER
IPC: E06C7/14
Filed: 1984-02-25
Abstract: The invention relates to a stepladder consisting of two ladder parts, with a tool shelf, in which the ladder parts in each case have two uprights interconnected via rungs or steps and are interconnected so as to be pivotable to a limited extent by means of joints in the region above the uppermost rungs or steps and can be adjusted into a predetermined spread position and a storage position, the uprights of the ladder parts lying on top of of one another parallel to one another in the storage position. The mounting of an easily accessible shelf without impairing the pivoting movement of the ladder parts and the compactness of the stepladder in the storage position is achieved by the shelf being arranged in the region of the upper ends of the two ladder parts between the upright ends and/or the uppermost rungs or steps and being connected to the ladder parts and by the shelf being dimensioned in such a manner that in the storage position of the ladder parts it does not project beyond the mutually turned away outer sides of the uprights, which run parallel to the rungs or steps.

Title: Travelling gear which is used for travelling over difficult terrain
Inventor: MEYER HEINZ THEODOR
IPC: B62D55/02
Filed: 1984-03-13
Abstract: The invention relates to a principle of travelling-gear construction which permits vehicles such as for example passenger vehicles, load-carrying vehicles or amphibious vehicles to overcome an obstacle with their own means. In order to fulfil these requirements, a track-laying mechanism was combined with a wheel work in such a form that the running face of the track-laying mechanism was raised until almost as far as the underfloor of the wheel work, larger running wheels (sing. R1) ensuring that travel is possible on a level road. The slope in the tracks (angle  alpha ) is to be defined here depending on the application area. In a travelling gear according to the invention, the overall size, size of the frame and the ratio of the components to one another etc. and the power of the engine depend on the area of use. The guidance of the chain above the running face is independent of the invention. <IMAGE>
Patent DE-3410890-A1 (DE)
Title: Daylight developing machine using the immersion method
Inventor: SITTE ERNST-ADOLF
IPC: G03D3/10
Filed: 1984-03-24
Abstract: In order to avoid a high construction outlay and operating errors which can occur substantially more easily in the dark than in the light, a daylight developing machine works using the immersion method entirely in the light and has only one cassette which transmits liquids and gases through angular slots, but no light, because the light propagates only rectilinearly. The cassette is well loaded with the film that is to be developed and then automatically sent through the various baths and washing operations.

Patent DE-3431297-A1 (DE)
Title: Padding machine
Inventor: GROSSMANN PETER
IPC: B29C65/50
Filed: 1984-08-25
Abstract: With this padding machine, workpieces made of leather or plastic, e.g. key containers, are provided with a cover strip and deformed under pressure and heating. Rapid and easy insertion of the workpieces and convenient manufacturing are made possible by movable elements of the machine (Fig. 1). In the machine, the upper end of a support column, which rests at the bottom on a footplate, is fixedly connected to a baseplate (3). The latter has two guides (4, 5), in which two sliding pieces (6, 7) slide, which are arranged in the two parts (8, 9) of a two-part sliding plate. They are pressed inwards by springs and outwards when a pedal is pressed. Connected to the baseplate (3) are two bearings (12, 13) for guiding a shaft (14) which has a central piece (15) with a square cross-section. Welded to this, offset by 180 DEG , are two tools (22, 23) with obliquely running outer surfaces (36, 37) corresponding to the workpiece. The workpiece, which is provided internally with the cover strip, is, when the pedal is pressed, put loosely onto the front tool (22). The shaft is then rotated by 180 DEG  until the workpiece comes to lie next to the sliding plates (8, 9). When the pedal is released, the sliding pieces (6, 7) are pressed against the outer surface of the heated workpiece and the external form is manufactured, the cover strip being adhesively bonded. <IMAGE>

Title: Periscope/telescope/afocal lens combination for magnifying the field of view
Inventor: GERNET HERMANN
IPC: G02B3/00
Filed: 1984-09-04
Abstract: Description of a periscope/telescope/afocal lens combination for magnifying the field of view of an observer by shifting a portion of the desired magnification of a conventional periscope magnification (e.g. 3.0) into an afocal lens in front of the periscope. Depending on the refractive index, centre thickness and radius of curvature of the outer surface of the afocal lens, portions of a desired periscope magnification can be achieved by the afocal lens. Because, by virtue of its special design, the afocal lens permits a wide field of view (visual field) for an observer, periscope/afocal lens combinations make it possible to achieve diameters of the field of view (visual field diameters) which are larger by approximately 50 % in conjunction with the same magnification (e.g. 3.0), and thus to provide substantially better viewing conditions.

Title: Electric coffee-making machine
Inventor: KAISER HELMUT
IPC: A47J31/44
Filed: 1985-02-01
Abstract: The invention relates to an electric coffee-making machine having a removable fresh-water container which has a handle. In this case, the object is to be achieved of increasing the operating convenience and safety of the appliance. To achieve this object, it is proposed to construct the handle (32) so as to be linked pivotably about a horizontal axle on the fresh-water container (8). This has the advantage that the user can hold the fresh-water container approximately centrally above the centre of gravity when inserting and removing it, as a result of which misalignments are avoided. Furthermore, when the handle is moved into its rest position, an attachment device can be actuated which fixes the inserted fresh-water container in its upper region on the housing of the coffee-making machine. <IMAGE>
Patent DE-3506414-A1 (DE)
Title: Cable traction system
Inventor: PIRAGS SIEGFRIED
IPC: B61B13/04
Filed: 1985-02-23
Abstract: In cable-driven traction systems, it is known to arrange the cable clamp on a transversely directed extension arm in the region of a haulage clip so as to be swivellable about a vertical axis. The extension arm is rigidly connected to a longitudinal strut connecting the haulage clips. As a result, in bends, the distance of the cable clamp from the travel rail varies. Difficulties arise when passing through cable roller guides. These disadvantages are avoided in that, for example by means of control and swivel cylinders 16, 15 which are coupled to one another hydraulically, the extension arm 14 is always positioned vertically with respect to the travel rail 1 and thus the cable clamp 23 is always held parallel to the travel rail 1. If the extension arm 14 is located at the end of a running gear 2, its swivel axis coincides with the swivel axis 7 of the adjacent haulage clip 4. When arranged between the end-side haulage clips 3, 4, the extension arm can be mounted so as to be also transversely displaceable. <IMAGE>

Title: Inflow pot for clean water in swimming pools or the like
IPC: E04H4/12
Filed: 1985-04-19
Abstract: In the case of swimming pools having a multiplicity of inflow pots 10 for clean water, in order, on the one hand, to achieve a uniform water-filling and, on the other hand, to make do with a relatively simple distributing pipe network for the clean water, a regulating plate 27 is arranged such that it can pivot and be fixed on the basic plate 13, of the inflow pot 10, containing numerous passage openings 22, 23. This regulating plate 27 has passage openings 32, 33 which are arranged coincidentally with respect to the passage openings 22, 23 in the basic plate 13, are intended for the clean water and open into distributing chambers 35 and 36 from which the clean water flows, at different outflow angles and in the form of a cylindrical stream, through nozzle gaps 37 and 38 into the pool. By pivoting the regulating plate 27 relative to the basic plate 13, the clean-water flow quantity can be selectively adjusted individually for each inflow pot 10, in each case according to the position of the latter on the base of the swimming pool, with the result that the desired uniform water-filling of the swimming pool is achieved. <IMAGE>

Title: Method of searching for data sequences which correspond to a pre-defined search argument and are contained in a hybrid associative memory
Inventor: WOLF GERHARD DIPL ING
IPC: G06F17/30
Filed: 1985-09-24
Abstract: A method by which it can be established whether a search argument is included in character strings, which are stored in a memory (B-SP), is given. The search is carried out using a logic device (ASS-FL), which consists of logic units (ALV0 to ALV63), which work autonomously and independently of each other. The first character of the search argument is fed from a parameter memory (PAR-SP) to the logic units (ALV to ALV63). Similarly, the first characters of the character strings (ZK0 to ZK63) which are stored in a field (F1) of the memory (B-SP) are fed in parallel to the logic units (ALV0 to ALV63) which are assigned to these character strings. Logic units which establish, for example, that the characters of the character string and those of the search argument are equal, output a hit signal (T), and the other logic units are blocked. The search procedure is then carried out with the second character of the search argument and the second character of the character string. The search procedure in a field (F) is always broken off if none of the logic units (ALV) outputs a hit signal, and otherwise when all the characters of the search argument correspond to all the characters of at least one character string in the field. If no character string of a field corresponds to the search argument, the search procedure in this field is broken off very quickly, since on average after two ...
