Patent DE-3904722-A1 (DE)
Title: Construction system for climbing installations
Inventor: HOFFMANN MICHAEL
IPC: A63B69/00
Filed: 1989-02-16
Abstract: Systems have thus far been lacking which allow the construction of a large number of climbing surfaces of different shapes and their problem-free reconstruction into other shapes. The construction system illustrated achieves this aim. It consists of different, geometrically shaped climbing plates (e.g. squares, various triangles, regular pentagons etc.). All edges of the same length of these plates can be coupled in any angular positions by means of separable hinges. In order to guarantee gap-free closing between coupled plates in any angular position, the edges of the plate are in each case half formed by a cylinder which is concentric with the axis of rotation of the hinges and half formed by corresponding cutouts. The diagram shows the corner of a square climbing plate with a one-part hinge part (a.), two-part hinge part (b.), the cylinder (c.) and the cutout (d.). The holes which arise at the intersection points (e.) of a number of plates are closed by corresponding fitting pieces. The climbing installations which can be erected with this construction system are either self-supporting (e.g. small closed towers) or require a stabilising carrier construction (e.g. larger towers or walls). They can be used in an ideal manner for training and in particular for competition purposes. <IMAGE>
Patent DE-3907046-A1 (DE)
Title: Process and apparatuses for plug formation in screw press separators
Inventor: EICHLER DIETRICH DR
IPC: B30B9/26
Filed: 1989-03-04
Abstract: The invention relates to a process and apparatuses for plug formation in screw press separators which serve for separation and pressing of solids from liquids, in particular fibrous constituents, from slurries which arise in removal of liquid manure from animal houses in animal husbandry. The aim of the invention is to increase the range of use and the flexibility of the screw press separators described in various patent applications and to increase the dry matter content in the solids. The object is achieved according to the invention by the counterpressure, which is required for the buildup, transport and discharge of the plug, being built up by the internal stress of the solids at the walls delimiting the plug parallel to the direction of transport. For this purpose, using a screw having constant pitch, the space provided for the plug formation is shaped in such a way that the solids plug, from the end of the screw to the discharge, forms a hollow cylindrical ring, about 70-80 % of its length is enclosed by the screen basket and is mixed and homogeneously compressed by a last screw turn running at 180-360@ to the screw core.
Patent DE-3907561-A1 (DE)
Title: Method for reducing the transparency of a wire link conveyor, and a wire link conveyor of limited transparency
Inventor: LEUVELINK GERRIT WILLEM
IPC: B65G15/54
Filed: 1989-03-09
Abstract: Wire link conveyors normally consist of plastic wire spirals lying alongside one another which interlock via their head bows and are connected by linking wires. Their transparency is too great for many application purposes and is therefore reduced by using inserts which are threaded into the spirals. In order to facilitate this threading-in and to hold the inserts in their axial position inside the finished wire link conveyor, the inserts used according to the invention are rubber-elastic filaments which, upon being threaded in, are axially stretched and then relieved of tension so that they bear on the windings of the spirals or interlock with them and the neighbouring spirals.

Title: Multi-disc clutch
Inventor: TERAOKA MASAO
IPC: H02K7/06
Filed: 1989-03-15
Abstract: A multi-disc clutch has the following: a cylindrical clutch housing which is fixedly coaxially connected to the first shaft, a clutch hub part which is fixedly coaxially connected to a second shaft, first friction plates which are in engagement with the cylindrical housing, second friction plates which are in engagement with the hub part, one second friction plate being arranged between in each case two first friction plates, a cylindrical clutch motor which is arranged coaxially with the first and/or second shaft, and a ball spindle which is arranged between the cylindrical clutch motor and the first and/or second shaft in order to convert the rotational movement of the cylindrical clutch motor into an axial movement thereof and to bring the two first and second friction plates into engagement with one another when the cylindrical clutch motor is operating. Since the clutch motor is arranged coaxially with the two shafts, it is possible to obtain a large clutch engagement force despite a small-sized motor.

Title: Optical fibre mfr. - by forming bar with sheath and core, stretching, fusing with outer tube and stretching
Inventor: WITTMANN MANFRED DR RER NAT
IPC: C03B37/012
Filed: 1989-04-27
Abstract: Optical fibres are produced in four stages.

Title: Control system for brushless DC motor for magnetic disc - has magnet poles and coils which have number of phases with current applied at one of phases for each specified time
Inventor: USHIJIMA NOBUYOSHI
IPC: G11B19/28
Filed: 1990-01-18
Abstract: In the motor control system, the current is re-applied to the same phase, without the application of current to the other coils during a part of a revolution. The status of the current rise is measured when the current begins to flow to the phase during the re-application of the current. The position of one of the mangmagnet poles lying opposite a phase is detected on the basis of the measured status of the current increase. In response to the positional detection of a magnet pole, it is determined whether the current flow to the next phase should be changed over or not, then the current is changed over to the next phase, if the current is provided for the changeover. - A constant speed control can be carried out, in which data from a driven disc can be read to determine the speed. This can be compared to an established speed, and a normal current, a braking current or an acceleration current can be selected.
