Inventor: SEGURA JOHN S
IPC: G05D21/02
Filed: 1990-07-19
Abstract: Efficient control of the pH of a flowing alkaline wastewater stream is accomplished by monitoring the pH of the flowing stream, generating a signal in response to the pH monitored, and injecting CO2 as necessary to reduce the pH.  High pressure liquid CO2 is supplied to a proportional control valve which is operated in response to the signal to change the high pressure CO2 fluid to an intermediate pressure CO2 fluid in a manner so as to significantly reduce its density by creating a significant gaseous fraction.  This lower density CO2 fluid is supplied to a spring-loaded injector having an orifice in communication with the flowing stream.  The intermediate pressure is above the pressure at which the injector opens whereby the lower density CO2 fluid is injected into the flowing stream, allowing particularly precise control to be achieved.

Title: Trailer landing gear cushion foot
Inventor: HUNGERINK GERALD W
IPC: B60S9/08
Filed: 1990-08-16
Abstract: A cushioned landing gear foot (40) is attached to the landing gear leg (12) by a tubular suspension axle (32) within a housing abutment member (26) on the lower end of the leg, and which abutment engages a resilient pad (50) in a pocket on the foot when under compression load. The abutment member (26) has a rectangular cross section including a flat bottom surface for abutting the pad. The clearance between this flat surface (in elevated condition) and the resilient pad is less than the potential vertical movement of the hollow suspension axle in a pair of slots (48) into which it extends. The pad retaining pocket includes a pair of fore-and-aft inverted L-shaped retaining walls (52) allowing approximately 20 degree fore-and-aft articulation of the foot on the leg, and approximately five degree side-to-side articulation. When the leg and foot are put under load, the pad will be deformed until a predetermined maximum force is applied to it, and then the axle will bear all load exceeding this predetermined amount. <IMAGE>

Title: Scanner with retractable roller feed
Inventor: BECK JEFFREY E
IPC: G06K13/063
Filed: 1990-11-20
Abstract: Title:  SCANNER WITH RETRACTABLE ROLLER FEED           ABSTRACT OF THE DISCLOSURE A scanner is operative with an imaging system for inducing a mechanical movement of a subject during an optical scanning of the subject to provide an image of the subject.  The subject which is in the shape of a card is advanced along a travel path past an optical viewing site by means of a drum, the scanner including a first roller and a second roller which urge the subject against the drum.  Initially, the first roller is located between the viewing site and the entry port for receipt of the subject in a first nip between the first roller and the drum.  The second roller is positioned fixed on the opposite side of the viewing site.  The first roller is supported by an arm which swings about a rotational axis of the drum to vary the spacing between the two rollers.  Upon rotation of the drum in a forward direction for induction of the subject, a brake located between the drum and the arm drags the arm and the first roller towards the second roller to facilitate a transference of a leading edge of the subject from the first nip to a second nip defined by the second roller and the drum.  Preparatory to optical scanning of the subject which is accomplished during reverse rotation of the drum, the arm swings the first roller away from the second roller to present the viewing site to the optical scanning beam.
