Title: Method for information transmission and network
Inventor: AYTAC SUNGUR
IPC: H04B10/272
Filed: 1985-08-29
Abstract: A plurality of subscriber stations (1, 2, 3, 4) in each case equipped with a transmitting and a receiving unit are linked by a network with a star-shaped structure. The signals transmitted from the individual subscriber stations to the star point (5) are combined to form a composite signal which is then amplified, the amplified composite signal then being forwarded to all subscriber stations and, in the subscriber stations, a specific signal part designated for the respective subscriber station being filtered out from the composite signal. Known coding and decoding methods can be used to ensure that the signal transmitted from a subscriber station can be received as required by all or only some of the other subscriber stations. Unlike conventional star-shaped networks with an active star point in which each subscriber station in the star point has its own assigned transmitting and receiving unit, the method according to the invention offers the advantage of a considerable simplification of the star point which is particularly evident in networks based on optical waveguides. <IMAGE>

Title: Stimulus generator for the neurophysiological stimulation of muscles, nerve paths and nerve cells through the skin and the skull cap
Inventor: LENSING JOHANNES DR RER NAT
IPC: A61N2/04
Filed: 1985-10-31
Abstract: There is described a stimulus generator which avoids the prior art deficiencies (induction of pain, uncontrolled stimulation far above the threshold) in that by specifying the charge necessary for a response, only that charge is effective in the tissue. This defined charge is fed to the stimulable tissue within a short time - in the microsecond range - either by a stimulating electrode with current-return electrode applied onto the skin or by means of a magnetic head through the magnetic field. Thus, this generator avoids unnecessary stimulation of the pain receptors of the skin.

Patent DE-3607198-A1 (DE)
Title: Drying container
Inventor: GREINER WOLFGANG
IPC: A23B4/03
Filed: 1986-03-05
Abstract: Drying and curing of goods in the meat and sausage goods industry is unsatisfactory, as when the goods are stored in containers with closed floors, only half of the surface of the goods comes into contact with the air in the cooling chamber, juice contained by the goods drips out of containers with holes and a multiplicity of different containers are required for transport and storage. These disadvantages are eliminated by the drying container which is formed by a vertically standing part which forms the side walls, holding devices, two grids and an interposed liquid-absorbing and air-permeable nonwoven fabric, and is designed in such a way that it can be used both as a transport and as a storage container.

Title: Internal combustion engine with exhaust emission control
Inventor: VOGELSANG FRIEDRICH-WILHELM
IPC: F01N9/00
Filed: 1986-04-29
Abstract: An internal combustion engine with exhaust emission control, especially a gas-operated internal combustion engine is equipped with a controlled catalytic converter in the exhaust line and with a lambda control circuit. The latter comprises a lambda probe, connected to the catalytic converter on the inlet side in the exhaust line and by way of a comparator circuit and final control elements intervenes in the fuel-air mixing process in the fresh gas line as a function of the signal from the lambda probe in order to meet the lambda window. The intention now is to isolate the catalytic converter in the exhaust line from the exhaust gas ducting whenever the lambda control cannot yet meet the lambda window when starting up the internal combustion engine or can no longer meet the lambda window during continuous operation due to faults. For this purpose a bypass to which gas is admitted by way of a reversing valve, arranged downstream of the lambda probe in the direction of flow of the exhaust gas, thereby avoiding the catalytic converter, when the lambda control circuit indicates departure from the lambda window, is connected in parallel to the catalytic converter.

Title: Device for preparing bristle material
Inventor: STEINEBRUNNER WALTER DIPL ING
IPC: A46D1/04
Filed: 1986-05-02
Abstract: A preparation device according to the invention for bristle material for the production of brushes in particular has a cutting device (1) for cutting lengths of bristles into bundles (3). The lengths of bristles have a plastic or paper strip wrapped around them and are held together by this wrapping. When cutting through the length of bristles there is the risk that the covering is partly pulled into the cutting region so that further processing of the bristle bundle (3) by machine is virtually impossible. According to the invention, there is provided in addition to a first clamping device, located before the cutting point in the conveying direction of the lengths of bristles, after the cutting point a second clamping device which acts on the bristle bundle to be cut and its covering during the cutting process. As a result, a relative movement between the covering and the bristles is at least reduced so that the covering is virtually no longer able to enter into the cutting region. As a result, further processing of the bristle bundles by machine can be carried out, in particular straightening can also be carried out in a simple manner. In order to make the best-possible use of the entire length of the length of bristles (2) cutting blades, which can be operated independently of one another, are provided before and after the first clamping device. As a result, the last bristle bundle at the end of a length of bristles can be cut at the rear end by this additional cutting blade, ... Original abstract incomplete. <IMAGE>
