Patent DE-3910451-A1 (DE)
Title: Method for cooling a three-phase alternator, and an oil-cooled three-phase alternator
Inventor: SAITO AKIHIRO
IPC: H02K9/19
Filed: 1989-03-31
Abstract: A method is specified for cooling a three-phase alternator which is driven by an internal combustion engine. The excitation winding (7) of the three-phase alternator consists of claw magnets (9) and a cylindrical core (8) so that an oil passage (12, 13) is formed in the zones in which the cylindrical core (8) and the rotor shaft (3) are opposite one another and in the zones in which the cylindrical core (8) and the claw magnet pole (9) are opposite one another. This oil passage (12, 13) is connected at one end to an oil supply located outside the three-phase alternator, so that oil can be introduced into the oil passage during operation of the three-phase alternator; a centrifugal force acts on the oil as a result of the rotation of the rotating excitation winding, so that the oil is sprayed onto the stator winding (23) in the form of vapour or mist. <IMAGE>

Title: Analysis of longitudinal mode structure of a laser - using band pass filtering to identify type of mode for indication via intensity independent threshold values
Inventor: BALZER WOLFGANG DIPL ING DIPL
IPC: H01S3/00
Filed: 1989-07-22
Abstract: A process used to provide information for the analysis of the longitudinal mode structure of a laser has the input provided by photo detectors (PD). The detector outputs are filtered (BP) and rectified (GL) to separate into different frequency ranges. The centre frequency of the band pass filter are multiples of the resonator fundamental frequency. Dividing stages standardise the signals to the first and second harmonic frequencies to generate intensity independent threshold values (SW). Logic interprets the outputs for activation of a display (ANE) indicating the identified mode of the laser. ADVANTAGE - Provides automatic indication of laser mode.

Title: Physical measurement apparatus for absolute measurement of refractive index - monitors position of mirror reflecting light refracted by system contg. specimen back into system
Inventor: BEYER KLAUS
IPC: G01N21/41
Filed: 1990-12-06
Abstract: The apparatus for the absolute measurement of refractive index reflects a measurement beam, which has already been deflected by a light refracting system contg. the measurement specimen (6) and a reference substance, back into the system via a retroreflecting mirror. - The mirror position is monitored by a photodiode (8) to which part of the retroreflected light is passed via a beam divider (3) in the optical path between the light source (1) and the light refracting system. The mirror position difference angle with and without the refracting system equals the system's deflection angle and hence forms a direct measurement parameter for the absolute value of the refractive index.

Title: Circlip with annular hole - has outer groove mounted on pin, and ring part pressing into inner groove
Inventor: KUEHNHOLD WOLFGANG DIPL ING
IPC: F16B21/18
Filed: 1991-03-22
Abstract: The circlip (8) has an annular hole for clipping into an inner groove (6) which has a sloping side (7) or for turning into the inner hole (2) in a ring-part (1). An outer groove (9) with radial clearance is mounted on a pin (3), especially for axially securing a serrated connection (4,5) between the ring part and pin. When unstressed, the pin's outer surface is axially non-round; the ring's (8) cross-section is even.

Patent DE-4118446-A1 (DE)
Inventor: GENTHE GUENTHER
IPC: F16J15/20
Filed: 1991-06-05
Abstract: In a method for producing rings consisting of pure graphite films, a graphite film strip is wound concentrically onto the core of a mould and is subsequently compressed in the axial direction. A cut which is oblique or is located parallel to the axial direction is subsequently carried out. During the compression, the graphite film strips are displaced within predetermined limits in the axial and radial directions of the ring which is to be pressed, which leads to a Z-shaped or multiple Z-shaped folding of the layers formed from the graphite film strips. After production of the cut through the pressed ring, the cut ends are preferably drawn apart from one another in the axial direction by an amount which corresponds approximately to the internal diameter of the ring, and the ring is subsequently subjected to a second pressing process. <IMAGE>
