Inventor: OUDELAAR TONE
IPC: F16K11/056
Filed: 1993-04-05
Abstract: The invention relates to a hydraulic circuit comprising at least two double acting hydraulic piston-cylinder devices, more particularly for opening and closing of a folding roof of a vehicle of the cabriolet type, in which both of the cylinder ends of each of the hydraulic piston-cylinder devices are each connected to a conduit supplied with pressurized fluid by a common hydraulic pump and to a return fluid conduit leading to a source of hydraulic fluid. The hydraulic circuit proposed by the invention is characterized in that the electrically actuated valves are 3/2-valves, with a check valve of the ball valve type in the surface connection for the pressure conduit. 
     More particularly the valves are of the so called ball seat type.

Abstract: A containment valve with two butterfly valves (27,29) at the juncture of a first port (23) and a second port (25) with the two valves pivoting on a common transverse axis (39). The ports may be coupled and uncoupled between a coupled mode and an uncoupled mode. In the uncoupled mode one butterfly valve body locks the first port shut and the other butterfly valve body locks the second port shut to isolate the contents of the ports, such as chemical dust. Each butterfly valve body has a circumferentially moveable annular locking ring (31,33) moveable between a first position and a second position. In one position the locking ring locks the butterfly valve body shut when the ports are in an uncoupled mode. In the other position the locking rings hold the two ports in the coupled mode. A spring biased pin lock (59,67) prevents inadvertent rotation of the annular locking ring. Annular ribs (237a) and grooves (137a) are provided on the mating faces of the butterfly valve bodies. The ports are hermaphroditic about both the X-axis and the Y-axis.

Abstract: A string instrument of the invention is capable of producing a stable amount of sounds from a low sound region to a high sound region. A vibration mode is measured when the frequency of a basic vibration of strings (6) becomes equal to that of a basic frequency of a top plate (9), and two stiffeners (20,22) of predetermined lengths are attached on the rear surface of a top plate along two nodal lines appearing on the top plate in that vibration mode. The stiffeners (20,22) do not affect in a low sound region but cause the vibration mode to change in a high sound region, thereby making it possible to produce increased amounts of sounds in every sound region, particularly that around the E-string for a violin which has been thought to be difficult for a conventional violin to produce.

Abstract: This invention relates to a method of cracking polymers, especially waste hydrocarbon polymers to produce products of lower molecular weight. The process comprises feeding the polymer into a processing chamber or circular-cross section which chamber also has a bed of particulate material maintained in suspension and in toroidal shape by a hot gas introduced into said chamber so that the polymer intermingles with the particulate materials of the bed and is cracked into products of lower molecular weight. The invention is useful for converting polymeric wastes into products of commercial value such as eg waxes, lubricants and monomeric olefins at the same time reducing environmental pollution.

Abstract: A collimation chamber (6) for use in physical vapor deposition of a wafer includes a device (5) for rotating a wafer (4) inside the collimation chamber during a deposition process. The device for rotating a wafer comprises a rotatable pedestal (5) which is positioned at the bottom of the collimation chamber. The means for depositing comprises a target (2) positioned above the rotatable pedestal. A collimator (3) is positioned between the target and the wafer. Two or more elements can also be reactively combined inside of the collimation chamber to be deposited on the surface of the wafer. A method for depositing deposition material over the surface of a wafer inside of a collimation chamber comprises the steps of rotating the wafer inside the collimation chamber and depositing a deposition marterial over the surface of a wafer while it is being rotated inside of the collimation chamber. The step of rotating the wafer inside the collimation chamber is accomplished by rotating a pedestal (5) which the wafer (4) is positioned on, the pedestal positioned at the bottom of the collimation chamber. The deposition material is deposited over the surface of the wafer by bombarding a target (3) with particles causing pieces of the target to be sputtered and deposited on the surface of the wafer. Reactive sputtering can also be accomplished by introducing gas particles of an element into the collimation chamber, the gas particles to react with the discharged particles from the target and form a reactive compound to be deposited on the surface of the wafer. The ions used to bombard the target are attracted towards the target by applying an appropriate voltage to the target. The method further comprises the step of collimating the discharged pieces from the target on their way to be deposited on the wafer.
