Title: Wrapping mechanism for the bales of a baler
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 1991-08-28
Granted: 1995-08-01
Abstract: A supply of wrapping material for a wrapping mechanism is provided in the form of a spool having a core member which is rotatably mounted to the lower ends of a pair of support arms having their upper ends vertically pivotally mounted to an arm support for pivoting about a horizontal axis.  An upright contact surface is located below the horizontal axis and is engaged by one side of the spool of material such that the surface offers frictional resistance to the unwrapping of material from the spool.  In order to keep this frictional resistance substantially constant through out the unwrapping of material from and consequent loss of weight of the spool, a biasing spring may be connected between the arm support and at least one of the arms and/or the surface can be configured or coated with frictional material such that the coefficient of friction of the surface increases in a direction away from the horizontal axis, this being the direction that the zone of contact between the spool and the surface travels as wrapping material is pulled from the spool during wrapping operation.

Title: Hydraulic shape memory material stress to hydraulic pressure transducer
Inventor: GROOM KENNETH N
IPC: F16D65/28
Filed: 1990-08-06
Granted: 2001-01-23
Abstract: A hydraulic shape memory material force converter is provided comprising a shape memory material. The force converter utilizes hydraulic units and a hydraulic fluid. The hydraulic unit is changed from a first position to a second position when the shape memory material, connected at one end to one end of the hydraulic unit and its other to a fixed point or a second end of the hydraulic unit, changes from a martensitic to an austenitic state upon heating. The hydraulic fluid responds to the movement of the hydraulic unit by moving from the hydraulic unit to a receiving device, which receiving device performs work due to the motion of the hydraulic fluid. Upon cooling the shape memory material to change it from the austenitic state back to the martensitic state, the hydraulic unit returns to its original position, with a biasing means being provided to return the hydraulic unit to its rest position.

Title: Simple compact ion mobility spectrometer
Inventor: THEKKADATH GOVINDANUNNY
IPC: G01N27/64
Filed: 1992-08-20
Granted: 2001-05-15
Abstract: A compact ion mobility spectrometer (IMS) with increased sensitivity and resolution for detecting the composition of an unknown substance is disclosed. The IMS comprises a unitary cylindrical housing, inlet means for introducing sample gas, outlet means for withdrawing sample and drift gas, two high voltage electrodes, and a detector. The first electrode is pulsed to inject sample ions through an opening located in a second electrode which defines a drift region. The second electrode is cup-shaped having an open end and is electrically biased to create a non-uniform electric field gradient across said drift region. The electric field in said drift region is axial and radial resulting in an increase in ion drift velocity at the detector and a corresponding increase in detected peak signal amplitudes thereby increasing resolution. A shorter drift region and the absence of an aperture grid near the detector which cause ion collisional losses, helps to increase IMS sensitivity.

Title: Method and apparatus for the purification of liquids
Inventor: MOREDOCK JAMES C
IPC: B01D35/18
Filed: 1993-02-05
Granted: 1999-07-13
Abstract: A purification method and device for purifying industrial oils from contaminates including a first container housing for receiving the industrial oil in bulk and separating liquid and particulate contaminates therefrom by reversing a flow direction of the received oil.  The thus processed oil is transferred to a second container and is subjected to a further filtration by forcing the oil under high pressure through at least one filter element accommodated in the second container.  The high pressure on the at least one filter element results in a compression of the at least one filter element thereby precluding the oil being processed from bypassing the filter element.  A further filter barrier seal element may be provided above the at least one filter element and serve as a final filtration prior to a discharge of the oil from the second container.

Title: Dual status thin-film eas marker
Inventor: TSAI CHING-LONG
IPC: H01F10/12
Filed: 1993-11-22
Granted: 2002-03-26
Abstract: A dual status marker for use with a magnetic-type EAS system has a signal-producing layer including at least one magnetic thin-film of high permeability and low coercive force such as permalloy, and a signal-blocking layer including at least one remanently magnetizable thin-film such as an Fe-Cr alloy. The remanently magnetizable thin-film or thin-films should have a total thickness at least equal to, and preferably at least twice, the total thickness of the magnetic thin-film or thin-films of high permeability.      By doing so, the marker is more reliably deactivated when the signal-blocking layer is magnetized. For even greater assurance of deactivation, the signal-blocking layer should include more than one remanently magnetizable thin-film, thus giving it a squarer B-H loop and greater assurance against false alarms.
