Abstract: ABSTRACT A control mechanism for opening and closing a window sash or like element pivotally mounted in a frame. The mechanism has a drive member mounted for rotation with an elongated drive shaft and a housing mounted on the drive member for rotation relative to the drive member and the elongated shaft. The housing includes a retaining mechanism which is subtended by a first portion of the drive member. A rod for reciprocating movement in response to rotation of the drive member is located between the retaining mechanism and the first portion of the drive member and held in direct contact with the drive member by the retaining mechanism. The rod has a first end attached to the window sash and also has cables connecting it to the drive member such that rotation of the drive member in a first direction causes longitudinal movement of the rod in a first direction, thereby opening the window, and rotation of the drive member in a second direction causes longitudinal movement of the rod in a second direction, thereby closing the window.

Abstract: PATENT     PCM AUDIO SIGNAL RECORDING               AND/OR REPRODUCING APPARATUS                  ABSTRACT OF THE DISCLOSURE          In a PCM  (pulse code modulated)  audio signal recording and/or reproducing apparatus, a scanning track formed by one scanning of a tape by a rotary head is divided into a plurality of track areas in its longitudinal direction to thereby form multi-channel segment track areas, and the PCM audio signal is recorded on and/or reproduced from the segment track area of each track corresponding to a particular channel on the tape.  When a plurality of programs or events are sequentially recorded in a timer scheduled recording mode, it is possible to select either a series recording mode in which successive events are recorded only in the segment track areas of one channel or a parallel recording mode, in which the successive events are recorded in segment track areas of different channels, respectively.

Title: Windshield wiper device for motor vehicles
Inventor: KUEHBAUCH GERD
IPC: B60S1/36
Filed: 1987-01-08
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE           A windshield wiper device for motor vehicles includes a cup-shaped housing whose jacket is in the form of a stationary inner transmission gear and whose bottom supports for rotation an oscilla-ting shaft driven by a drive.  The oscillating shaft is firmly connected to a two-arm swing lever.  One arm of the swing lever supports for rotation a shaft Journal whose one end is firmly con-nected to a transmission gear and whose other end is connected to a control crank.  The one arm also supports slide guides for guiding a wiper arm in a radial direction relative to the oscillating shaft.          The control crank is linked to the wiper arm to impart thereto an oscillatory movement in the radial direction.  The other arm of the swing arm lever support for rotation an intermediate transmission gear.  A two-sided toothed transmission belt connects the interme-diate transmission gear with the other transmission gear and the toothing on the outer side of the transmission belt engages the stationary inner gear, thus imparting a rotary movement to control the other transmission gear.

Abstract: PROCESS FOR LASER HARDENING DRILLING         BIT CONES HAVING HARD CUTTER INSERTS               Abstract of the Disclosure A medium to high carbon steel body (30) of a roller cone (20) for a drilling bit is machined to final dimensions, and is thereafter rendered absorbent to laser light by application of black paint or black etch.  Holes (46) for hard tungsten carbine inserts (42) are drilled in the light absorbent steel body (30).  The steel body is irradiated by a laser beam (52) which is effective to raise to above austenitizing temperature only the dark light absorbent surfaces.  Walls (48) of the insert holes (46), being shiny, reflect the laser light and are not affected by it.  Rapid self-quenching of the laser heated surfaces results in a hard martensitic layer (54) in the external surface.  In an alternative process, hard tung-sten carbide inserts 42 are press fitted into the holes (46) before the laser treatment.  The subsequent laser treatment does not affect the inserts adversely, because the inserts, too, have shiny light reflective surfaces, and therefore do not absorb the laser light.
