Inventor: SARUWATARI MINORU
IPC: F04B47/04
Filed: 1993-12-31
Granted: 1996-09-17
Abstract: A hydraulic drive system for actuating a reciprocating member such as a polished rod in a pump jack device, and for acting as a counterbalance and/or for energy conservation. The system has two hydraulic circuits and a prime mover. A first circuit includes a cylinder for driving an output member which may be connected to the polished rod, a first pump of the variable displacement, reversible flow type, together with a pair of fluid lines forming with the cylinder a closed-loop circuit.          A controller is programmed to control the setting of the first pump so as to establish the velocity profile of the output member. A second hydraulic circuit is also in the form of a closed-loop containing first and second pumps, at least one of which is of the variable displacement type and is also controlled by the controller. The second and third pumps at least are of the pump/motor types, and the third pump has an input/output shaft connected to a flywheel so that as the third pump is driven as motor, it increases the speed of the flywheel. However, when the second circuit is controlled so that the second pump functions as a motor and the third pump functions as a pump, energy is extracted from the flywheel so that its RPM decreases.           The first pump is driven by the prime mover, and the second pump, which can drive the first pump when it is functioning as a motor, may alternatively be driven by the prime mover as well or by both the prime mover and the first pump, if the latter functions as a motor, such as during the down stroke of the polished rod.

Title: Process for producing low molecular-weight poly-1-olefins
Inventor: BOHM LUDWIG
IPC: C08F10/00
Filed: 1994-01-06
Granted: 2005-03-29
Abstract: A catalyst formed by the reaction of a magnesium alkoxide dispersion having a particle size of from 100 to 3000 nm with a compound of a metal selected from the group comprising titanium, zirconium, vanadium and chromium and then with a chlorine-containing organoaluminum compound possesses a very good hydrogen responsiveness and a high activity even in the presence of molecular-weight regulators such as hydrogen. The catalyst is therefore outstandingly suitable for the production of low molecular-weight polyolefins. The catalyst makes possible the production of waxes having a reduced residual ash content. The large particle diameter and the low fines content of the polymer powder produced by suspension polymerization with this catalyst enables easy removal of the suspension medium and drying. The catalyst is furthermore advantageously used in solution polymerization and, because of the large particle diameter, in gas phase polymerization for producing low molecular-weight poly-1-olefins.

Granted: 2005-10-18
Abstract: These and other objects of the present invention are achieved by an apparatus for coating product with two colors which includes a first coating section, a second coating section and a means for transferring products from the first to the second sections. The first section includes a feeding and loading station for depositing products onto product holders retained in product carrier plates. The products are advanced to a first dipping station in which a vacuum chamber having the plurality of vacuum tubes engages a plate and inverts and dips the products to coat a first portion of the product. The plates are then advanced to a first rotating station where another vacuum chamber and vacuum tube device engages the plates and rotates the plates one revolution for spreading the coating over that first portion. The plates are advanced to an elevator where they are raised incrementally to a dryer that extends over the first section of the coating apparatus. The plates are transferred into the dryer where they traverse through the dryer in a controlled manner for curing the coating applied to the first portion. The plates are transferred to a down elevator and returned to the conveyor where they are advanced to a side to side transfer apparatus. The transfer apparatus transfers the products to the second section of the coating apparatus in such a manner to expose on carrier plates the uncoated portion of the products. The plates are then advanced to identical dipping and rotating stations as in the first section and then transferred by an elevator up to a second dryer located above the conveyor in the second section. The plates traverse the second dryer and are returned to the second conveyor by a down elevator where the plates are advanced to an unloading and discharge apparatus. the empty plates are then advanced to the side to side transfer where they are recycled for future use in the apparatus.

Title: Strand displacement amplification using thermophilic enzymes
Inventor: FRAISER MELINDA S
IPC: C12Q1/6844
Filed: 1995-03-13
Granted: 2001-10-23
Abstract: Strand Displacement Amplification methods (thermophilic SDA) which can be performed over a broad temperature range (37°C to 70°C). The preferred temperature range for thermophilic SDA is 50°C to 70°C. It has been found that certain thermophilic restriction endonucleases are capable of nicking the hemimodified restriction endonuclease recognition/cleavage site as required by SDA and dissociating from the site.  It has further been found that certain thermophilic polymerases are capable of extending from the nick while displacing the downstream strand. Thermophilic SDA, because of reaction temperatures higher than previously possible with conventional SDA enzyme systems, has improved specificity and efficiency, reduced nonspecific background amplification, and potentially improved yields of amplification products. In addition, the need to add the enzymes in a separate step after the initial heat denaturation of double stranded targets is eliminated when enzymes capable of tolerating the denaturation temperature are used.
