Patent number: 8567355Abstract: An integrated control system for use with an engine connected to a generator providing electrical power to a switchgear is disclosed. The engine receives gas produced by a gasifier. The control system includes an electronic controller associated with the gasifier, engine, generator, and switchgear. A gas flow sensor monitors a gas flow from the gasifier to the engine through an engine gas control valve and provides a gas flow signal to the electronic controller. A gas oversupply sensor monitors a gas oversupply from the gasifier and provides an oversupply signal indicative of gas not provided to the engine. A power output sensor monitors a power output of the switchgear and provide a power output signal. The electronic controller changes gas production of the gasifier and the power output rating of the switchgear based on the gas flow signal, the oversupply signal, and the power output signal.Type: GrantFiled: December 22, 2010Date of Patent: October 29, 2013Assignee: Caterpillar Inc.Inventors: Paul Sai Keat Wang, Darryl Baldwin, Myoungjin Kim

Patent number: 8414227Abstract: A device for collecting items from a container comprises a collection unit, a conduit, a vacuum producing unit and a controller. The conduit is in fluid communication with the collection unit and is mountable to the container so as to be placed in fluid communication therewith. The vacuum producing unit produces a vacuum within the conduit. The controller is linked to the vacuum producing unit and is configured to acquire data regarding the contents of the container. When the controller receives data regarding the contents of the container it controls the vacuum producing unit to modulate the vacuum produced within the conduit thereby suctioning the items within the container when mounted thereto into the collection unit. The container can be a transit fare box for receiving items tendered for fare. The data regarding the contents of the container can be the volume of items within the container.Type: GrantFiled: September 2, 2009Date of Patent: April 9, 2013Inventor: Gilles Tardif

Patent number: 4971481Abstract: The present invention describes a stop device for stopping a carrier traveling in a pneumatic tube. The invention also includes a terminal comprising the stop device. The stop device includes a pneumatic tube having an exhaust aperture and a shutoff aperture and a pressure sensing monitor in fluid communication with the shutoff aperture. The pressure monitor senses the pressure change in the shutoff aperture caused by the carrier's movement past the shutoff aperture and activates a switch shutting off the pneumatic source. The carrier impacts an end stop and settles down on a catch which was also activated by the pressure monitor. The carrier is held in front of a door through which the carrier may be readily retrieved.Type: GrantFiled: February 10, 1989Date of Patent: November 20, 1990Assignee: Communications Conveyor Co., Inc.Inventor: Michael J.

Patent number: 4930941Abstract: A customer terminal for a single tube pneumatic system for banking and the like features a two-piece carrier receiver which includes a carrier tray that first moves downwardly from a stationary receiver housing and then forwardly and upwardly to present a carrier in the tray to a customer, the tray and carrier remaining parallel to the receiver housing. The tray is resiliently mounted to the mechanism which manipulates it and the joint between the tray and housing is contoured both to improve sealing between the two parts and to reduce wear on the seal itself. The air pressure/exhaust ports into the carrier chamber within the receiver are disposed between the ends of the chamber in order to provide an air cushion for reducing the shock of an arriving carrier and to prevent loose items in the system from being sucked into the blower.Type: GrantFiled: November 21, 1988Date of Patent: June 5, 1990Assignee: Inter Innovation LeFebure Mfg.

Patent number: 4320559Abstract: Hides are pulled from animal carcasses in a slaughterhouse, and conveyed upwardly through a pneumatic conveyor conduit for further handling. The conduit tangentially enters a vacuum chamber which is connected to a vacuum source. The chamber has a lower discharge opening which is normally closed by a gate; however, when a hide arrives in the chamber from the conduit, the vacuum is reduced to enable the gate to open and release the hide through the discharge opening.Type: GrantFiled: December 7, 1979Date of Patent: March 23, 1982Assignee: Iowa Beef Processors, Inc.Inventor: William F.

Patent number: 4259031Abstract: A method and apparatus for feeding material intermittently discharged from one machine, primarily an injection molding machine, to another machine, primarily a granulator mill. The feeding-in operation offers low energy consumption, great flexibility as regards material particle size and discharge rate for the grinding material, as well as minimal hazard risk. A predetermined amount of material is collected in a receiving compartment whereafter the collected material amount is moved along a supply path into the granulator mill by means of one or more currents of driving gas which flow through the receiving compartment and are led off from the supply path before reaching the granulator mill itself. The driving gas which is discharged intermittently only during the actual feeding cycle also opens a pivotal flap disposed in the supply path and preventing goods being subjected to grinding from being flung out of the granulator mill.Type: GrantFiled: June 20, 1979Date of Patent: March 31, 1981Assignee: Maskin AB RapidInventor: Sven-Inge Axelson
