Title: Pace-maker transmission for rotary engine
Inventor: RUDOLF FRITZ
IPC: F01C1/077
Filed: 1986-07-16
Abstract: Pair of piston shafts 2 and 3 coaxially arranged in the housing 1 for rotary engines with circular slideway, each piston shaft with at least two or more pistons rotating in the slideway of 1, which pistons act by way of inlet and exhaust ports, where necessary also ignition and injection devices in the housing 1, and therefore with automatic control because an A-B-C transmission according to the invention keeps the pair of piston shafts 2-3 in suitably progressive rotational movement whilst the drive and/or output shaft turns uniformly. This A-B-C transmission, which has a connection to the coaxial pair of piston shafts 2-3 projecting out of the housing 1 through disc cams B and C of elliptical geometry toothed according to the invention or cam rims B and C of elliptical geometry, is actuated by way of an axially parallel drive or output shaft 4 by means of a transmission part A, identical to this, which comprises two such fixed disc cams or rims offset in the working stroke, if necessary also toothed, balanced ellipses. This provides the rotary engine with a suitable automatic control function.

Patent DE-3637097-A1 (DE)
Title: Optical broadband communications system, in particular in the local loop
Inventor: KUEPPERS DIETER DR RER NAT
IPC: H04B10/2581
Filed: 1986-10-31
Abstract: For short-distance optical transmission systems, in particular for optical waveguide transmission paths in the local loop, it is proposed to operate the monomode optical waveguides standardised for long-distance traffic and optimised for the 1300-1600 nm wavelength range with optical transmitters (S) and optical receivers (E) whose operating wavelength lies significantly below the limit wavelength of the optical waveguides and, by means of suitable stable coupling of the laser (S) with the optical waveguide (1), to ensure that the monomode operation required for the transmission of digital signals at high bit repetition rates is achieved. Optical transmitters and optical receivers of this type are already available at low cost today, so that the development work deemed to be necessary in the literature in order to reduce the cost of optical components adapted to the optimum transmission range of the optical waveguide (1) does not need to be carried out. The increased attenuation of the optical waveguide at 800 nm compared with the longer wavelength range can be accepted due to the relatively short length of the lines in the local loop. Even two-way transmission using wavelength division multiplexing is possible via a single optical waveguide (1) according to the principle of the invention. <IMAGE>

Title: Automatic safety belt, especially for motor vehicles
Inventor: RASKOV OLEG
IPC: B60R22/44
Filed: 1986-12-22
Abstract: An automatic safety belt, especially for motor vehicles, includes on the one hand a belt reel (7) which is preloaded in the winding-up direction and preferably a toothed wheel (11), which rotates concomitantly with the latter, and a detent pawl. The detent pawl is only activated when the belt is tightened rapidly to ensure that the safety-guaranteeing function is carried out and blocks the belt reel against further unwinding. In order to be able to relieve the load on the safety belt to some extent without impairing the safety-guaranteeing function, there is furthermore provided a return lock (13) which includes a locking element (15) which only engages in, and therefore blocks, the toothed wheel (11) in the event of a slow reverse movement on the part of the safety belt (5) and a resulting reverse rotation on the part of the belt reel (7) in the winding-up direction at a rotating angle speed which is less than a limit value (Figure 1). <IMAGE>

Title: Arrangement of a laminated stator core, which carries alternating magnetic fluxes, of an electrical machine
Inventor: ROSENBERG HEINZ DIPL ING
IPC: H02K1/16
Filed: 1987-05-19
Abstract: In the case of a known arrangement of this type, a bridge consisting of non-magnetic material is arranged between the laminated stator core and the housing of the machine. In the case of this arrangement, the stray magnetic fields are intended to be damped inductively by the eddy currents induced in the bridge. This results in additional losses, and the intrinsic heating of the bridge prevents the dissipation of the heat losses produced in the stator. The novel arrangement is intended to reduce the stray flux levels passing through the housing in comparison with known arrangements without bridging by the bridge and to avoid additional losses in the bridge, with the adverse effect, resulting therefrom, with respect to heat dissipation from the laminated stator core. For this purpose, the bridge (4; 9; 10; 12; 19; 21) has a construction which suppresses eddy currents. An electrical machine having a laminated stator core which carries alternating magnetic fluxes. <IMAGE>
