Title: Method and apparatus for transferring a drilling apparatus from a movable vessel to a fixed structure
Inventor: YEARGAIN CHARLES WESLEY
IPC: B63B35/00
Filed: 1991-11-06
Granted: 2001-08-14
Abstract: A skidbase (16) and a drilling structure (18) are adapted for transfer between a jack-up platform (12) and a fixed platform (14). The jack-up platform (12) is moved into position adjacent the fixed platform (14) and raised to a height aligned with the fixed platform (14). The skidbase (16) is then transferred onto the fixed platform (14) to provide a base on which the drilling structure (18) is next placed. The jack-up platform (12) is raised to a vertical height aligned with the skidbase (16). To ensure proper location of the top surface of the jack-up platform (12) relative to the skidbase (16), a connection means (47) automatically engages and aligns the jack-up platform (12) with the skidbase (16) so that skid rails (32, 44) located on the deck of the jack-up platform (12) and on a top surface of the skidbase (16) are positioned a precise distance apart and at the same vertical height. The drilling structure (18) is then skidded onto the skidbase (16) so that drilling operations may be performed from the fixed platform (14). The connection means (47) takes the form of a multi-dimension blade member (128) affixed to the skidbase (16). The blade member (128) progressively engages a series of guide members (122, 124) on the jack-up platform (12) and, thereby, progressively and stagewise aligns the skidbase (16) as the jack-up platform (12) is moved to its desired vertical height.

Abstract: A suction inlet for a central vacuum system of a building includes a housing capable of being mounted on the floor of a building in a fixed position and defining a slot along the  floor.   Slot can be opened and closed and simultaneously a vacuum duct connected to the housing is opened and closed by a plug member.  When the plug and the slot are opened, an electrical switch actuates the central vacuum system to draw air into the housing through the slot across the floor so that dust, dirt and debris on the floor can simply be swept into the slot and drawn away.  The plug member can be moved to the open position by a foot operated lever that pivots about a pivot point on the housing.  The plug member is biased towards a closed position where it prevents  dust  and dirt  from being drawn through said housing and into said vacuum duct.

Granted: 2003-09-09
Abstract: An isolator surge protector for use with corrosion protection systems which are an inherent part of or coupled to an electrical power system, for power transformers, and for DC transmission systems, where it is necessary to present a high impedance to DC and a low impedance to AC up to a predetermined voltage level. Anti-paralleled thyristors in the isolator surge protector turn on during power surges. A bypass circuit insures turn off of the thyristors after a triggering event such as lightning or a 60 Hz surge has ended. The bypass circuit shunts DC bias currents, such as that which may be provided by a DC bias voltage source for cathodic protection, from the thyristors to ensure that the voltage across each thyristor falls below its holding voltage or current, and thus prevents the thyristor from being stuck in a continuous conduction mode. Power to operate the bypass circuit may be tapped from the surge which caused the thyristor to trigger so that the bypass circuit operates autonomously. The circuit may also operate with an auxiliary power supply to provide the required operating power and to turn off the thyristors.

Granted: 1998-07-14
Abstract: A quick service limiting valve device for a freight brake control valve employing a primary valve in a fluid flow path via which brake pipe air is connected to the brake cylinder during a secondary phase of quick service to propagate the brake pipe reduction signal until the brake cylinder pressure acting on the limiting valve control piston effects closure of the primary valve to terminate the quick service flow of brake pipe air to the brake cylinder when a predetermined brake cylinder limit pressure is realized.  A secondary valve is arranged to interrupt the brake pipe to brake cylinder flow path downstream of the primary valve in the event leakage at the primary valve causes the pressure acting on the quick service limiting valve control piston to exceed the predetermined limit pressure.   Until this limit pressure is  exceeded,  the secondary valve is bypassed so that only the primary valve controls the brake pipe to brake cylinder flow path via the limiting valve, thereby reducing hysteresis due to friction to obtain more efficient limiting valve operation.

Abstract: In a direct-sequence spread-spectrum receiver, spread orthogonal data signals and spread orthogonal pilot signals are correlated with orthogonal despreading sequences at a chip rate.      These despread signals are integrated at a symbol rate to produce orthogonal data symbols and orthogonal pilot symbols.      A predetermined number of pilot symbols of each phase component is moving-averaged. Each phase component of the orthogonal data symbols is weighted with the moving average value of the corresponding phase component of the pilot symbols, and summed with the other weighted component of the data symbols to produce an output signal of the spread spectrum receiver.

Abstract: Methods of assaying for the presence of enzymatically active hydrolases (i.e., hydrolytic enzymes) in a sample or specimen are disclosed. In particular, a method of detecting candidiasis by assaying for the presence of enzymatically active aspartic protease in a sample is provided. In these methods, a sample or specimen is contacted with a solid support. The solid support with which the sample is contacted has a reporter enzyme (i.e., a signal generating enzyme) immobilized thereon. The reporter enzyme is immobilized the solid support in a manner such that it is released from the solid support upon action of the enzymatically active hydrolase if the enzymatically active hydrolase is, in fact, present in the sample. The sample after having been contacted with the solid support is combined with an indicator. The indicator is any chemical species which is susceptible to a detectable change, usually a change in color, upon action of the reporter enzyme. A detectable change in the indicator is an indication that the enzymatically active hydrolase is present in the sample. Moreover, the presence of an enzymatically active hydrolase in a sample may indicate the presence of a particular pathogen or disease state such as, for example, candidiasis. In addition to the methods of assaying for the presence of enzymatically active aspartic protease and other hydrolytic enzymes, a dry, self-contained test device for assaying for the presence of an enzymatically active hydrolase in a sample is disclosed. In particular, a dry, self-contained test device for testing a sample for the presence of candidiasis by assaying for the presence of enzymatically active aspartic protease is also disclosed. These test devices combine a reporter enzyme immobilized on a solid support, an indicator, and all other reagents and components necessary to achieve a detectable indication of the presence or absence of the enzymatically active hydrolase whose presence is being detected in the sample, and preferred embodiments contain positive and negative controls as well.
