Title: Method for making disposable cartridges for photocopiers and laser printers reusable
Inventor: WILCKE GERHARD
IPC: G03G21/18
Filed: 1987-01-16
Abstract: Disposable cartridges for smaller photocopiers and laser printers often have, besides a fresh-tuner container and a residual-toner container, further parts which are functionally important, such as photoconductor drums and loading and developer stations, the additional parts being of considerable significance for the price of the cartridge. The invention is based on the idea of making such disposable cartridges reusable. This is achieved by a method according to which the toner containers of the disposable cartridges are later provided with refill and discharge openings which can be closed by covers, adhesive strips, or stoppers.

Abstract: Device for the monitoring of threads guided between two components, preferably for textile machines, the threads being moved between these components so as to form a balloon, with a sensor which has a piezoelectric element and which converts vibrations caused by the running thread into electrical signals used for monitoring. In order to allow a simple construction and so that, in addition to a thread break, the rotational speed of the balloon can also be recorded, provision is made for the sensor to be arranged between two components and to have a small baffle plate which is connected to the piezoelectric element, whilst the thread or twist movable between the components transversely in addition to the conveying direction touches the small baffle plate in a pulse-like manner.
Patent DE-3707133-A1 (DE)
Title: Curtain glider
Inventor: VIEL PAUL
IPC: A47H15/04
Filed: 1987-03-05
Abstract: Conventional curtain gliders can only be pushed in from the end of the rails. If gliders are overlooked during the pushing-in, this can only be rectified by taking the curtain down again and starting the pushing-in operation anew. This causes the arms to tire. With the new type of glider, subsequent insertion at any point on the curtain rail is possible. This facilitates the work not only for housewives but also for interior designers. The new type of curtain glider can be inserted into the common types of curtain rail, conversion not being necessary. Only the existing gliders themselves need to be replaced.

IPC: H04L25/04
Filed: 1987-06-12
Abstract: In a method for equalising digital signals at the receiving end of a line section, first a positive and then a negative isolated test pulse or vice versa are transmitted at the distant receiving end of the line section, a predefined number of sample values are derived from the distorted signal which is produced in each case from the test signal and which occurs at the receiving end of the line section, a mean value is calculated in each case from the temporally identical sample values of both distorted signals following inversion of one of them and the mean values are stored in a coefficient memory and serve to correct the digital signals.
Patent DE-3720573-A1 (DE)
Title: Tool which can be releasably inserted in a borehole casing string
Inventor: SPEEGLE STEVEN S
IPC: E21B34/10
Filed: 1987-06-22
Abstract: Tools which are releasably inserted in a borehole casing string have a landing device and an axial locking device so that they are fixed in operation, that is, under the forces of the flow medium pressing upwards and the gravitational force pressing downwards. These tools are let down by an assembly tool on a rope into the borehole or the production casing string or are pulled up again while neutralising the axial locking. In the rare case of such a tool jamming through formation pressures or contaminants and no longer being able to be pulled up again, it is necessary to drill out the tool with a drill or a cutter. In the process it is possible for the tool to rotate in the casing string, and the drill or cutter may be unable to remove any material. The measures according to the invention prevent rotation of the tool when it is being drilled out.

Title: Asparagus-peeling device and carrot-peeling device
Inventor: HORNSTEIN HELMUT
IPC: A47J17/08
Filed: 1987-07-01
Abstract: The object of the invention is to develop a small hand machine into which the asparagus is inserted and the latter is completely peeled by a special knife arrangement with rotary action. The object was achieved according to the invention in that claw knives are mounted on springs in a housing 6, which knives, by rotation of the inner housing, then adapt all around to the body of the asparagus and peel the latter as a result of the pulling through and pushing through. The claw knives are so designed that on inserting asparagus or carrots the respectively correct diameter of approx. 8-28 mm is ready for peeling. Furthermore, by pushing or pulling from the rearside a slight rotation of the inner housing, and thus also of the knives, is obtained, thereby achieving a clean peeling action.

Title: Automatic device and associated container for dispensing food to animals, in particular domestic animals, such as dogs and cats
Inventor: VIDAL SOLE JUAN
IPC: A01K5/02
Filed: 1987-12-28
Abstract: Automatic device and associated container for dispensing food to animals, in particular domestic animals, such as dogs and cats. The feeding of domestic animals during absence of the owner lasting for days is problematic because helpful neighbours are not always available, taking the animal along is often impossible and accommodation in a special animal home is in general too expensive. The invention solves this problem by means of a device which, with desired periodic repetition, automatically prepares two vessels or containers, to which the animal gains access; one of them contains semi-solid food including the varying diet for the animal, while the other is filled with liquid food such as e.g. milk or water. The device is suitable, for example, for feeding animals in the case of an absence of a week, two groups of in each case 7 containers being served to the animal, i.e. two containers each day.

Patent DE-3812849-A1 (DE)
Inventor: KLIMMEK ALBRECHT
IPC: B01D39/18
Filed: 1988-04-18
Abstract: The dust filter bag comprises a filter paper outer layer and a fine fibre non-woven fabric, each having characteristic specific properties. The fine fibre non-woven fabric can, if required, be reinforced by a supporting element. The combination of appropriate filter materials for the filter paper outer layer, the fine fibre non-woven fabric and the supporting element leads to high degrees of removal of fine dusts, and, at the same time, low air resistance and a low tendency to filter clogging. The multilayered filter bags can, according to the individual design, be manufactured on corresponding bag machines. The outstanding filtration properties allow the dust filter bags to be used for the removal of particles greater than or equal to 0.1  mu m in vacuum cleaners of the most diverse types, and also in the removal of toner by suction in copiers. Furthermore, the combination of the filter materials described in the form of flat filters, pleated filters, belt filters and roll filters is suitable for use in clean room technology, e.g. in semiconductor manufacture, film manufacture or in the hospital sector.

Title: Method and apparatus for the generation of cold by means of a magneto caloric cyclic process
Inventor: SANDER MICHAEL DIPL PHYS DR RE
IPC: F25B21/00
Filed: 1988-12-21
Abstract: In a process for the generation of cold by means of a magneto caloric cyclic process, a pressurised fluid conveyed in circulation between a heat sink and a heat source is brought into heat contact with a plurality of magnetic materials arranged in steps. At the same time, the fluid, coming from the heat sink, is cooled in stepped contact, a part stream of the fluid quantity being branched off after each step. After heat exchange with the heat source, the fluid is heated again in the opposite direction, with the branched-off part streams being admixed in steps. The process can be used for liquifying the fluid, in that the fluid quantity cooled in the lowest step is expanded so as to generate cold. Hydrogen or helium gas, for example, can serve as fluids.
