Abstract: ABSTRACT OF THE DISCLOSURE           The installation and recovery of a structure or tem-plate which forms a tubular support structure for subsea equip-ment used in drilling and producing offshore oil and/or gas wells.  The template contains production manifolding, remote and safety shut-in control, pump-separator, and pipeline connector subsystems.  Certain of the structural tubes are segregated to form compartmented ballast chambers capable of being selectively flooded and dewatered.  Certain other structural tubes form piling sleeves.  The truss or framework of structural tubes include vertical and horizontal tubes, the latter forming circum-ferential members as well as interstitial supports.  The upper-most of the circumferential members or "ring" also functions as a fender to protect the equipment within the template.  The template is made negatively buoyant upon launch by flooding the compartmented ballast chambers, keelhauled (swung to a position underneath the keel of the drilling vessel), and then lowered to the subsea floor.  Once it is positioned on the sea floor the subsea structure is oriented, pile founded and leveled.  The template functions as a drilling and casing guide frame ensuring that drilled wells are connectable to the preinstalled manifold-ing.  The template is recoverable by severing the piles and deballasting the compartmented ballast chambers.

Inventor: RICHTER GERHARD
IPC: G01N27/49

Granted: 1982-07-06
Abstract: ABSTRACT OF THE DISCLOSURE          A method for determining the concentration of sugar in the presence of interfering foreign substances, particularly for determining glucose in a body fluid, by means of an electro-catalytic sugar sensor which has a measuring electrode in which the measuring electrode is alternatingly set potentiostatically to a reactivation and a measuring potential and the current flow-ing during the measuring period is evaluated as the measurement signal.  To prevent foreign substances from exerting an interfer-ing influence and thereby permit a sensitive sugar determination which is reliable over an extended period of time, a hydrophilic diaphragm is arranged in front of the measuring electrode to impede the resupply of the interfering foreign substances to the measuring electrode so that a diffusion limit current adjusts itself during the reactivation phase in the oxidation of the foreign substances; and the current is evaluated with a time delay relative to the start of the measuring period.

Abstract: Abstract Disclosed is an apparatus and method for fumigating stored agricultural commodities such as grain and the like, includes an applicator for porous envelopes or sachets of prepackaged pesticides of the type which react with moisture in the air and produce a toxic gas.  The applicator comprises an elongate strip constructed of a flexible, porous, non-hygroscopic material.  The strip has two plies which are arranged in an overlying relationship and are interconnected along a side edge thereof, and includes a plurality of seams which extend laterally across the strip and regularly inter-connect the plies, and form pockets shaped for receiving the prepackaged pesticide sachets therein.  The seams form a flexible hinge between adjacent pockets and interconnect the same to facilitate folding.  A sachet is inserted into each pocket, the pocket is closed, and the filled applicator is deployed onto the free surface of an aggregation of stored commodity and arranged in a flat and fully extended position thereover.  Water vapor in the air infiltrates the applicator and sachets and reacts with the pesticide to form a gas which permeates the commodity storage and fumigates the same.  After the sachets have completely degassed, and the grain depository is vented, a free end of the applicator is grasped, and the same is longitudinally rolled or folded accordian-style along the seams, thereby quickly retreiving each of the gassed sachets, without adulterating the commodity with pesticide residue.

Abstract: ABSTRACT OF THE DISCLOSURE            A water heater supplies hot water at a variable flow rate, depending on demand, and at a substantially constant, controlled temperature.  It comprises a heat exchanger formed with an inlet and an outlet whereby water can be supplied to and withdrawn from the heat exchanger in accordance with demand and means for passing a second fluid such as steam through the heat exchanger coil to heat the water.  A temperature gradient is thus established in the water in the direction of its flow through the heat exchanger.  A sense tube forms a substantially homogeneous mixture of different portions of the water, these portions being drawn from sampling points spaced apart along the temperature gradient and in relative proportions depending on the flow rate of the water through the heat exchanger.          The temperature of the water in the sense tube is detected, and control means responds to the sensed temperature for controlling the rate at which steam is supplied to heat the water.  Thus a combined set point and feed forward control is established that minimizes fluctuations in the temperature of the hot water as withdrawn for end uses by anticipating changes in BTU requirements.

Abstract: Abstract of the Disclosure A band clamp device of the invention employs a U-shaped housing (16) for the drive worm screw (14) usually formed by progressive stamping from sheet metal.  The separate arms (32) of the U embrace the edges of the band (10) and the respective separate arm ends (34,36) extend beneath the band.  The housing can have a single ear only (38 or 40 ) on one of the said separate arm ends extending through a slot in the band to connect the housing to the band.  Usually the housing will have a single ear (38 or 40) at each end, and the single ear adjacent the screw head end (18) is provided on the said separate downside arm end (38), which is the arm end that receives the maximum force tending to spread the housing arms apart as the band is tightened about an object.  It is found that such a structure is able to resist the forces tending to spread the housing arms and to separate the housing from the band, and it permits a wider ear to be used, or alternatively a narrower band for the same width ear.  For greater strength the two immed-iately adjacent edges of the arm ends can be joined together e.g., by a welding operation.
