Abstract: The invention concerns an impact compactor (10) which comprises one or more out-of-round compactor masses (14). The masses are moved rotationally over a soil surface, at an angular velocity suitable for normal operation, to apply periodic compaction blows to the soil surface. This is achieved by primary drive means. In the case of a towe d impact compactor, the primary drive means is typically a tractor. The impact compactor (10) includes an auxiliary drive which is arranged to operate automatically, in response to a reduction of the angular velocity of the compactor masses below the angular velocity suitable for normal operation, to apply an auxiliary rotary drive that restores their angular velocity.

Granted: 2004-04-27
Abstract: An electrochemical device includes a transparent first electrode (106) and a second electrode (110) distributed in localized areas. An electrolytic solution (112), disposed between and in electrical contact with the first and second electrodes, contains ions (116) of a metal which can electrodeposit on the first and second electrodes. Atoms of this metal (114) are deposited on the first or the second electrode. A negative electrical potential applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the first electrode, thereby affecting the propagation of electromagnetic radiation (122) through the device.       Conversely, a positive electrical potential applied to the first electrode causes deposited metal to be dissolved from the first electrode and electrodeposited from the solution onto the second electrode, thereby increasing the transmissivity of the device.

Abstract: The invention relates to a stretching device for a saw chain arranged to be active between a holder and a guiding device. A piston is arranged in a displaceable manner at the holder in parallel with the longitudinal direction of a saw bar. The piston has an engaging surface intended to grip an opposing surface an the guiding part.      The engaging surface and the opposing surface are located in parallel planes and these planes are arranged at an angle to a plane perpendicular to the longitudinal axis of the saw bar. The piston, when it grips the surfaces, affects the guiding part with a force whose components act partly in the longitudinal direction of the saw bar to stretch the saw chain and partly in a direction across the longitudinal direction of the saw bar to achieve a stabilising gripping of the parts that move in relation to one another.

Title: Moisture indicator for wet pick-up suction cleaner
Inventor: JOHNSTON LINDA N
IPC: A47L11/34
Filed: 2001-06-20
Granted: 2007-01-16
Abstract: The moisture sensor and indicator for a wet pickup vacuum cleaner, more particularly a wet extraction type carpet cleaner, is positioned in the suction duct to sense when water droplets or moisture is traveling through the suction duct.  An indicator is activated to indicate to the operator that water is being extracted from the carpet. The sensor may alternatively be located in the bottom of the floor-engaging portion where it contracts the floor. When the degree of moisture in the carpet exceeds a predetermined threshold an indicator is activated to indicate to the operator that the floor is still wet and to continue extracting moisture from the floor. Alternatively, the moisture sensor can be used as a safety device on a dry pickup vacuum cleaner. When moisture is detected within the suction duct, the motor-fan assembly of the dry pickup vacuum cleaner is disabled to prevent a potentially hazardous condition. Also, another moisture sensor is positioned in the cleaner to detect when the moisture level of the solution or recovery tank is reaches a predetermined level. An indicator is activated to indicate to the operator when the moisture level reaches the predetermined level.
