Title: Molded pull fitting
Inventor: VON HOLDT JOHN W
IPC: B65D47/10
Filed: 1987-09-02
Granted: 1991-08-20
Abstract: MOLDED PULL FITTING     ABSTRACT OF THE DISCLOSURE     A molded wall carries a pull fitting which may be improved by this invention as follows:  the pull fitting defines a tubular wall having an axis transverse to the molded wall, with the tubular wall being connected to the molded wall outside of the tubular wall by an annular, thin film of wall material integrally connected to both the tubular wall and the outside molded wall.  The tubular wall also defines  on its outer surface, an annular groove proportioned in size and shape to receive in snap-fit relation an annular edge of the outside, molded wall which is exposed upon severing of the annular, thin film and removing the fitting  Thus, the fitting may be reattached to the molded wall.

Title: Transmitter with an improved span adjustment
Inventor: FRICK ROGER L
IPC: G01L9/12
Filed: 1987-10-08
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE          A transmitter senses a process variable and provides a two-wire output adjusted by a span adjustment. The transmitter has a sensor which senses the process variable and provides a sensor signal.  An output circuit provides a two-wire output representative of the sensed process variable.  A span-controlling circuit is coupled between the sensor and the output circuit and receives a span adjustment. The span-controlling circuit includes an amplifier coupled to a potentiometer which adjusts the span based on the span adjustment.  The wiper of the potentiometer is connected to the amplifier output so that one portion of the potentiometer resistance provides feedback from the amplifier output to the amplifier input.  A second portion of the potentiometer resistance is coupled between the amplifier output and the output circuit.  Both portions of resistance affect both the span and the resolution of the output.  The arrangement provides an improved resolution over a wide turn-down-ratio.

Title: Diisocyanates, a process for their production and their use in the production of polyurethane plastics
Inventor: KOENIG KLAUS
IPC: C07C263/10
Filed: 1987-11-30
Granted: 1991-09-17
Abstract: DIISOCYANATES, A PROCESS FOR THEIR PRODUCTION AND THEIR USE IN THE PRODUCTION OF POLYURETHANE PLASTICS                 ABSTRACT OF THE DISCLOSURE    .alpha.-(4-isocyanatophenoxy)-.omega.-(4-isocyanato-3-methyl phenoxy)-alkanes and mixtures thereof with the corresponding methyl-free and/or dimethyl substituted diisocyanates are made by phosgenating the corresponding diamine(s).  These diisocyanates do not form a precipitate when reacted with a polyol and produce polyurethanes having outstanding properties.
Patent CA-1324199-C (CA)
Inventor: IWAMOTO TARO
IPC: G05B19/427
Filed: 1987-12-08
Granted: 1993-11-09
Abstract: Abstract:        The present invention relates to an improvement in a controlling apparatus of a manipulator equipped with a master arm and a slave arm.  The improvement is comprised of a processing device for effecting a scale conversion calculation of a calculation result representing the position data of the master arm for expansion or reduction. The processing device outputs the result of this calculation to the slave arm.
