Patent DE-19858366-A1 (DE)
Title: Proportioning and dilution technique for preparation of extremely dilute gaseous calibration samples of volatile substances
Inventor: SOHN HOLGER
IPC: B01F23/10
Filed: 1998-12-17
Abstract: Gas mixtures of standardized composition are prepared with a capillary diffusion system, mixing constant proportions of the substance of interest with the carrier gas stream, passing the primary gas mixture through a low temperature trap to separate the substance of interest, purging a controlled amount of the same or a different gas through the trap to re-suspend the substance of interest and provide the required concentration and charging the product gas mixture to an evacuated container.  Gas mixtures of standardized composition are prepared from a carrier gas in admixture with very low concentrations of volatile substances, by using a capillary diffusion system to mix constant proportions of the substance of interest with the carrier gas stream. The primary gas mixture is passed through a low temperature trap to separate the substance of interest. A controlled amount of the same or a different gas is purged through the trap to re-suspend the substance of interest and to provide the required concentration and the product gas mixture is charged to an evacuated container. Preferred Features: Mixing of a constant proportion of the substance of interest with the carrier gas stream is performed at an upstream pressure of approximately 50-200 kPa. The product gas mixture is at a pressure of 1000-10000 kPa. Typical capillary dimensions for preparing a mixture of trace aromatics in nitrogen or air are 5 cm length by 0.1 cm diameter for benzene, 0.2 cm for toluene, and 0.4 cm for xylene and ethylbenzene.
Patent DE-19902107-A1 (DE)
Title: Displacement control device for a hydraulic unit such as a hydrostatic transmission of skid-steer loader
Inventor: LOUIS JOSEPH E
IPC: F04B49/12
Filed: 1999-01-20
Abstract: A bias coupling is operatively interposed between a displacement varying movable member, an actuator, and a control valve assembly (14) which has a spool (26) and sleeve (22) that are displaceable with respect to each other. The bias coupling provides a preload force which must be overcome before the sleeve and spool can move with respect to each other and thus apply hydraulic assistance for stroking the unit. The sleeve moves synchronously with the spool until a feedback force exceeds a preload force whereupon relative displacement of the spool and the sleeve occurs so as to generate a control signal to a servo (16), which causes the servo to supplement the operator input force in moving the movable member to vary the fluid displacement of the unit.
