Patent DE-3136172-A1 (DE)
Title: Appliance for comminuting and composting garden waste
Inventor: ENGHOFER EMIL
IPC: B02C18/06
Filed: 1981-09-12
Abstract: In an appliance for comminuting and composting garden waste, there is attached to the motor shaft of a lawnmower a sheet-like sliding body possessing cutters pointing downwards and having the same effect as known separate choppers. The cutters are arranged in specific geometrical positions on the sliding body, so that a perfect cutting result, on the one hand, and a collection of the cut pieces in the region of the lawnmower, on the other hand, are achieved. The sliding body serves, on the one hand, for the mounting of these cutters, and on the other hand prevents the lawnmower from penetrating too deep into the accumulation of garden waste, over which the lawnmower is pushed to and fro, and for this purpose the sliding body can consist of a full-surface metal disc or else also merely of a skeleton (for example, a perforated disc) which likewise satisfies these conditions.

Title: Making contact to a stack of piezoelectric platelets
Inventor: HECK WOLFGANG ING GRAD
IPC: H01L41/047
Filed: 1981-12-21
Abstract: Stacks of piezoelectric platelets are used, for example, to operate valves. Contact should be made, on the one hand, simply and, on the other hand, it should enable the pressure to be transmitted over as large a surface as possible. This is achieved if every second platelet projects out of the stack in such a way that the electrode coatings are partly exposed, with the result that they themselves form the planar contacts. To connect contacts to be wired in parallel, printed circuit boards are used whose conductor tracks are soldered to the electrode coatings. <IMAGE>
Patent DE-3202957-A1 (DE)
Title: Process for the treatment of a graphite or ceramic fibre
Inventor: SEXTON RICHARD W
IPC: D01F11/12
Filed: 1982-01-29
Abstract: The invention relates to a process for producing metallic matrix composite materials reinforced by ceramic or graphite fibres, wherein the fibres are pre-treated; first they receive a nickel coating, then a second coating which is usually copper and is lost on dipping the fibres finally into a molten metal bath which becomes the matrix of the resulting composite material. Furthermore, for certain matrix metals, an additional third coating comprising a noble metal, for example silver, can be applied to the fibres. The nickel coating preferably has a minimum thickness of 0.5  mu m, and the second coating which is lost also has a minimum thickness of 0.5  mu m. After the two or more than two successive coatings have been applied to the fibres, the fibres are incorporated in a metal matrix composite material by, for example, dipping them into a bath of the desired molten matrix metal or bringing them into a suitable mould and pouring the molten metal around them. This can take place under ordinary atmospheric conditions without the use of reduced pressure or an inert gas atmosphere.

Title: System for the digital transmission of video or videotelephony signals
Inventor: SANCTIS MASSIMO DE DR ING
IPC: H04J3/07
Filed: 1982-07-24
Abstract: The invention relates to a multiplex device for the digital transmission of video or videotelephony signals at the bit rate of a PCM quaternary system of 139.264 Mbit/s according to CCITT G 703, where the analog video or videotelephony signal is coded to a bit rate of 135 Mbit/s and is characterised by low-cost synchronous multiplexers and demultiplexers on the transmitting/receiving side of the subscribers or the broadband switching centres, with 64 kbit/s signal scaling. The modular design is advantageous, which allows any combinations of different narrowband signals, changing in any way, to be additionally transmitted. Also advantageous are the elimination of the delay jitter which occurs in the switching centre when padding techniques are used, the minimum queuing memory requirements and the fact that, in the switching centres, for signalling identification only the signalling channel needs to be separated from the BB/NB multiplex signal and fed back to it, whereas, in padding-multiplexing techniques, total division into the individual signals and recombination of the multiplex signal are required (Fig. 4). <IMAGE>
