Inventor: SCHAEFER K-D
IPC: G11B9/08
Filed: 1988-07-07
Abstract: Arrangement for reading out data in the form of an electrical charge distribution in a multilayered film (1), in which   - a plurality of electrodes (5) are fitted opposite one another in a fixed position in relation to one another on a surface region of the multilayered film (1), - the electrodes (5) have regions (15) which are effective for information recording and form a plane parallel to the surface region of the multilayered film (1), - the electrodes (5) are relatively movable in a controlled manner parallel to the surface region of the multilayered film (1).   Presented here is a version for electrophotography and the application as a RAM. If MNOS technology is used, pixel sizes of about 2  mu m and a grid spacing down to about 10  mu m are feasible, it being possible for the storage in the pixels to take place in analog form with a dynamic range up to about 10<3> or in digital form. <IMAGE>

Title: Device for feeding weft threads on warp-knitting machines, especially stitch-bonding machines
Inventor: WIERZGON ACHIM DIPL ING
IPC: D04B23/12
Filed: 1988-09-06
Abstract: The invention relates to a device for feeding weft threads on warp-knitting machines, especially stitch-bonding machines, which inserts the weft-thread group into the hooks of a transport chain by means of a thread feeder, the thread feeder being movable to and fro by an adjustable crank mechanism via a pulling means. The object of the invention is to provide a device for feeding weft threads on warp-knitting machines, especially stitch-bonding machines, which allows an adjustable catch, which is independent of the speed of the thread feeder and which guarantees a reliable transfer of the weft threads onto the hooks of the transport chain. This object is achieved, according to the invention, in that adjustable stops are provided at the reversal points of the thread feeder and the pulling means is connected to the thread feeder via a connection means of variable length. The connection means possesses a resistance which inhibits the length variability and which must be equal to or greater than the drive force necessary for moving the thread feeder. This connection means of variable length can, for example, be a pretensioned spring.

Title: Expresso machine
Inventor: LEUSCHNER UDO DIPL ING
IPC: A47J31/46
Filed: 1988-12-23
Abstract: It is proposed to design an expresso machine such that the coffee prepared is delivered selectively through a greater or lesser number of outlets into receiving vessels, such as cups, placed underneath. For this purpose, it is proposed that the expresso machine has a distributing attachment capable of being attached by an inlet opening to an outlet, in the case of which distributing attachment the coffee flows from the inlet opening via a distributing device to two or more outlets of the distributing device. This solution has the advantage that the distributing attachment can be constructed so as to be easily removable for cleaning purposes and, given its simple design, is highly user-friendly. <IMAGE>
Patent DE-3844007-A1 (DE)
Title: Tool for lathes or milling machines
Inventor: KUEBLER-TESCH JOACHIM
IPC: B23B27/14
Filed: 1988-12-27
Abstract: Plate-shaped tools with a corner cut-out which does not extend up to the opposite corner so that no new cutting edge can be put into use by turning it are the state of the art. The disadvantage of such a tool consists in the fact that its tip has only a single cutting edge, after the wear of which the tip is unserviceable. The object of the invention is to achieve longer life than in tips with a single cutting edge. This object is achieved by virtue of the fact that the corner cut-out (26) is designed as an edge recess (12), that is, it connects two plane-parallel main faces (18) of the tip (10), with which the parallel base faces (28) of the cutting element (14) of straight cylindrical shape are coplanar. The advantage of this solution consists in the fact that, after the cutting edge on one main face of the tip has sustained wear, the tip can be turned in order to put the cutting edge at the other main face into use, so that the life of the tool is roughly doubled without doubling the cost of production. <IMAGE>

Title: Process and apparatus for the drying of dry articles, in particular alcohol-dressed foundry cores
Inventor: KASCHKE RAINER
IPC: F26B25/00
Filed: 1989-02-21
Abstract: The process and apparatus are used for the vacuum-assisted drying of a dry article which contains a liquid or a solid which on heating liberates volatile and/or explosive and/or environmentally polluting constituents, in a container, in particular for the drying of alcohol-dressed foundry cores. The vacuum vessel (1), which is warmed by indirect heating, is charged with the dry article (K). As a result of heating, the volatile constituents escape from the dry article. By means of the recovery plant comprising vacuum pump (6), compressor (7), cooler (8) and collection vessel (5), the volatile dress components can be reused in the separator (9). The energy recovery plant (10) uses the heat of vapourisation to be applied for heating purposes by means of the cooler (8). Uncondensed but combustible gas components are used for energy production via the heating system (2). <IMAGE>

Title: Overload safety device for stone crusher - leaves jaws in open position after failure of shear pin
Inventor: THOMAS PETER
IPC: B02C1/02
Filed: 1989-07-12
Abstract: The stone or mineral crusher is of the jaw breaker type. It has a frame (1) which supports a portal frame (8). The uprights (9) of this portal frame form the attachments for the fixed jaw (5) and the moving jaw (6).
