Title: End of Stroke Cushion for a Linear Hydraulic Motor
Inventor: FOSTER RAYMOND K
IPC: F15B15/22
Filed: 1994-02-17
Abstract: An end of stroke cushion for a linear hydraulic motor.  A piston-cylinder unit includes a cylinder body (42) reciprocally slidable on a piston rod (40) having a piston head (64) which defines working chambers (82, 84) within the cylinder body (42).  The piston rod (62) is tubular and includes a plurality of sidewall ports (P1-P7). A radially-expandable annular valve ring (106) normally snugly surrounds the piston rod (62) and during axial movement of the cylinder body (42) relative to the piston rod  (62),  the valve ring  (106)  will move axially relative to the sidewall ports (P1-P7) in the piston rod (62). Pressure introduction to the working chamber (84) through the sidewall ports (P1-P7) of the piston rod (62) and against the valve ring (106) radially expands the valve ring (106).  This allows oil flow to move into the working chamber (84) such that when the chamber (84) expands, the cylinder body (42) and valve ring (106) will move axially relative to the sidewall ports (P1-P7),  successively uncovering the ports  (P1-P7)  during movement.  Removal of fluid from the working chamber (84) will cause oil movement out from the chamber (84), through the sidewall ports (P1-P7) into the tubular piston rod (62) such that when the linear motor (10) approaches the end of its stroke, the valve ring will close the sidewall ports (P1-P7) in the piston rod (62) which allows oil flow out from the working chamber (84) in succession.

Filed: 1994-03-01
Abstract: Abstract: Display device including a field distortion correction circuit, and field distortion correction circuit.     When, for example horizontal lines are displayed on a display screen of a display device, they may exhibit a field distortion, predominantly in the form of gulling distortion which becomes manifest as a sinewave-shaped line instead of the horizontal line to be displayed. To correct this field distortion, a correction is generated by means of a field distortion correction circuit and a resonant circuit, dependent on the location on the display screen, which correction is added to the field deflection current so that the picture to be displayed is corrected for this error.

Title: Touch point identification algorithm for automatic clutch controller
Inventor: SMEDLEY DANIEL G
IPC: F16H61/04
Filed: 1994-07-18
Abstract: This invention provides automatic and reliable determination of the touch point of a clutch controlled by an automatic clutch actuation controller. This invention determines the touch point upon power-up while idling the engine, with the transmission in neutral and an input shaft brake applied. The clutch actuation controller gradually engages the clutch so that the measured transmission input speed matches a reference speed signal preferably between 40% and 60% of the idle speed. If the actuation is slow enough, this reliably provides the degree of clutch engagement at a small torque matching the braking torque which is the touch point. If there is no previous knowledge of the touch point, the clutch is applied at a fast rate and an approximate touch point is determined, then the clutch is positioned below the approximate touch point and is again applied at a slow rate to more accurately ascertain the touch point. If there is previous knowledge of the touch point, the clutch is positioned just below the old touch point and is applied at a slow rate to determine a new touch point. The new and old touch points may be combined to determine the updated touch point. <IMAGE>

Title: Water decontamination system with dimmer-controlled ultraviolet lamp
Inventor: SZABO LOUIS
IPC: C02F1/78
Filed: 1994-09-26
Abstract: ABSTRACT OF THE DISCLOSURE    An ultraviolet-based or dual mode water purifying system operates under household water pressure to provide a batch treatment of contaminated water.  Treated water is stored in a pressurized reservoir, from which it may be released for use.   A treatment cycle is initiated by a drop in pressure within the system, which occurs when sufficient water has been withdrawn from the reservoir.  The pressure drop is detected by a pressure gauge linked to a UV lamp dimmer, which causes the UV lamp to change from a reduced-output standby mode to an operative mode.    The dimmer may be further linked to a thermostatic switch positioned adjacent the lamp, to reduce the  output  of  the  lamp when  the temperature  exceeds  a predetermined level,  and to a backwash event control,  to increase the lamp output to the operative level during filter backwash.    The UV lamp may also be employed to generate ozone, which is reacted with the water in an ozone/water contactor upstream of the UV water exposure chamber, and that constitutes a helical tube with ozone being introduced to the fluid at the base of the tube and permitted to rise with the fluid through the tube.  A filter may be provided between the contactor and the UV exposure chamber to remove suspended particles.
