Patent DE-2416569-A1 (DE)
Title: Windscreen wiper blade for high speed travel - with stronger spring and stops to limit bending of blade
Inventor: FRIETSCH KURT
IPC: B60S1/34
Filed: 1974-04-05
Abstract: The wiper arm is coupled to the wiper stub by a hinge and by a special spring connected tothe stub away from the hinge to exert a torque on the wiper arm. A special flange of the stub mounting is fitted with a stop which limits the amount the spring can pull the wiper arm inwards. This enables strong spring forces to be used while limiting the force exerted on the wiper blades. The system is especially useful for high speed travel, when wind forces would tend to lift the blades off the windscreen.

Title: Measurement of extremely small losses in glasses - with glass specimen irradiated by linearly polarised light at Brewster angle
Inventor: HEITMANN WALTER DR ING
IPC: G01N21/59
Filed: 1974-05-09
Abstract: The linearly polarised light is a quasi-monochromatic parallel light beam of as high and constant intensity of radiation as possible which is produced by the optical imaging (3, 4, 5) and filtering (6, 7) of the radiation from a tungsten halogen lamp (1). The loss of the glass specimen (9) is determined from the difference DELTA I of the radiation intensities Io and ID of the same light beam which are measured with and without the glass specimen by a radiation detector. The reflection and surface scattering are measured separately and used to correct the measured difference DELTAI.

Title: Bearing housing for high speed shafts - comprising two parts with inlet and outlet for gravity lubrication
Inventor: MACINNES HUGH
IPC: F16C33/10
Filed: 1975-04-22
Abstract: A bearing housing device for high rotational speeds has two parts for receiving a shaft and a bearing, which surrounds part of the shaft, whereby the shaft combines at least two rotatable elements producing shear loads at a distance from one another. The first part has equipment to admit a fluid and to move it away and a first sealing arrangement to seal the first part along the shaft; the fluid lubricates the shaft and the bearing. The second part is fastened to the first and takes up axial loads on the bearing and has a second sealing arrangement to seal against the shaft. A third seal prevents loss of fluid between the two parts of the housing. The housing is used for turbo-chargers or other parts with high rotational speeds. It can be manufactured cheaply by die-casting. The compressor end seal is small, reliable, and much cheaper and sealing in the axial direction is improved; the housing can be arranged for gravity oil feed.
