Patent DE-3713349-A1 (DE)
Title: Process for producing a knitting needle, in particular the stiff needle end piece of a circular knitting needle
Inventor: NYSTEN BERNHARD DIPL ING
IPC: B29C45/00
Filed: 1987-04-21
Abstract: In the production of a knitting needle, the stiff needle end piece is produced by an injection-moulding process and the sprues remaining on the actual needle body in the resulting blank require complicated post-finishing. To save this extra work, it is proposed to design the sprue at the rear needle end and only to introduce the moulding material into the mould from this point. The sprue and, in particular, its attachment point at the needle do not need to be post-finished, because coupling means for connection parts have to be applied at this point in any case, for example a bore, and such a sprue is then removed at the same time.

Patent DE-3719670-A1 (DE)
Title: Method for the transmission of information, in particular for telecommunications systems
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/34
Filed: 1987-06-12
Abstract: Simultaneous outgoing and incoming transmission of information via a 2-wire line is possible only at great cost. In the case of long-distance connections, feedback circuits should also be avoided, which in particular is possible in 4-wire mode only. These disadvantages are avoided in the invention by coding the information in both directions using the amplitudes of the half-waves or cycles in each case of an alternating current of the same frequency, the two alternating currents being phase-shifted through 90 degrees in relation to each other. In the case of common electric circuits, the two alternating currents are then added together in the manner of quadrature amplitude modulation so that the information is retained.

Patent DE-3738078-A1 (DE)
Title: Vehicle tyre
Inventor: JANUS JONNY
IPC: B60C9/20
Filed: 1987-11-10
Abstract: Vehicle tyre with toroidal body made of elastic material and radial inlay In known radial tyres, the required reinforcement against transverse forces can only be achieved inadequately and with a high degree of outlay particularly in the edge region of the belt. The new arrangement is intended to remedy this and to improve the lateral and oblique running rigidity of vehicle tyres, in particular radial tyres. In the new vehicle tyre, a reinforcement structure made of super-thin platelets which interact with one another mechanically is arranged between the radial inlay and the carcass into the rubber material of the body of the tyre, the said structure leaving the tyre with the necessary degree of flexibility but, when lateral forces act, forming a rigid plate structure which supplies the necessary lateral and torsional rigidity. The new arrangement permits the belt to be of more simple design because it has to absorb virtually no lateral forces.

Patent DE-3805357-A1 (DE)
Title: Circuit arrangement for dynamic range control of speech signals
Inventor: WALKER MICHAEL
IPC: H04M9/08
Filed: 1988-02-20
Abstract: The circuit arrangement serves to control the dynamic range of the speech signals in a communications system terminal, e.g. in a videophone with a hands-free device. The signal-to-noise ratio is lower in a hands-free device than in telephones with handsets. In order to prevent feedback whistle, the known hands-free device has a dynamic range control with which, when the amplification in the transmit path is increased or reduced, the amplification in the receive path is reduced or increased to the same extent. The object is to use the maximum loop gain without reducing the amplification in the receive path. The idea is to connect a controllable dynamic range compander downstream of the microphone in which the signal voltages A supplied by the microphone are compressed when they are above a predefined signal level, are expanded when they are below the predefined level, and are amplified to the maximum extent when they are at the predefined level. The predefined signal voltage value, which corresponds to the compression starting point, is set by means of a control circuit depending on ambient noise. <IMAGE>

Title: Method for dressing rotary grinding tools
Inventor: BRILL JUERGEN DIPL ING
IPC: B24B53/08
Filed: 1988-08-13
Abstract: A method and apparatus for dressing rotary grinding tools are proposed, wherein, before each dressing cycle, the active surfaces of the grinding tool (3) and of the dressing tool (17) must be brought into a position of contact relative to one another, from which the actual dressing cycle begins. To determine the said contact between the tools (3 and 17), a quantity which changes during contact, for example the structure-borne noise or the torque, is measured by means of corresponding sensors (27). In order to achieve a very precise contact measurement here, the rotational speed of at least one rotary tool, the grinding tool (3) or, if appropriate, the dressing tool (17), is reduced in the approach phase of the two tools. A precise measurement of the contact of the two tools enables small defined dressing amounts to be set, so that economical, efficient dressing is possible. <IMAGE>
