Inventor: LAAK REIN
IPC: E03F1/00
Filed: 1998-05-19
Granted: 2005-02-08
Abstract: A leaching field constructed from a plurality of rectangularly shaped elongated geotextile covered in-drain core elements (16, 18, 20, 24, 26) provided alongside one another. The elements have equally spaced fold lines (16a, 16c, 16e, 16g) extending laterally across their adjacent semi-folded portions so that a stack of such elements in a flattened condition occupies a minimal space whereby these elements can be readily transported to the site.      When expanded honeycomb configuration is achieved so that a self-supporting in-drain structure greatly facilitates construction of the leaching field without the need for templates and the like to support the structure during the filling of the voids between the adjacent in-drain elements themselves. If desired, expandable stakes may be used to support the in-drain assemblies in an optimum configuration.

Title: Cavitated insulating support base for hot water tank
Inventor: LESAGE CLAUDE
IPC: B65D90/06
Filed: 2000-03-10
Granted: 2008-02-05
Abstract: A hot water tank is comprised of a cylindrical disc-shaped support base on which is supported a cylindrical inner tank concentrically therewith. A circumferential ridge projects upwardly adjacent an outer peripheral edge of the support base and spaced from a lower edge portion of a circumferential side wall of the inner tank to form a circumferential containment channel between the ridge and the lower edge portion. The channel has a volume sufficient to receive a lower portion of a plastic film pouch wrapper disposed at least about a lower section of the inner casing as well as a pre-determined quantity of hot expandable liquid urethane placed therein in sufficient quantity to fill a space between the inner casing and an outer shell secured spaced about the inner casing when the urethane is expanded. The channel prevents the liquid urethane from flowing out of the lower portion of the wrapper located therein due to deterioration of the wrapper when exposed to the hot liquid urethane.

Abstract: Coefficients of an adaptive filter are updated in response to a far-end signal and an error signal by using internal coefficients. The adaptive filter operates for generating a first pseudo echo signal in response to the far-end signal. A main filter operates for generating a second pseudo echo signal in response to the far-end signal. A decision is made as to whether or not the coefficients of the adaptive filter and the internal coefficients in the updating process should be initialized. In cases where it is decided that the coefficients of the adaptive filter and the internal coefficients in the updating process should be initialized, a tap length of the adaptive filter and the updating process is set to a non-original value smaller than an original value, and then initialization of the coefficients of the adaptive filter and the internal coefficients in the updating process is executed. The coefficients of the adaptive filter are transferred to the main filter when certain conditions are met. In cases where transfer of the coefficients of the adaptive filter to the main filter is executed after the tap length of the adaptive filter and the updating process is set to the non-original value, the tap length of the adaptive filter and the updating process is set to the original value, and then initialization of the coefficients of the adaptive filter and the internal coefficients in the updating process is executed.

Abstract: A pipe bending machine, a segmented bending die for use in a pipe bending machine, and a method for bending pipe are disclosed. The pipe bending machine includes a frame, a segmented bending die, a support structure, a stiffback, and a pin up shoe. A pipe is inserted in the pipe bending machine, over the pin up shoe, between the segmented bending die and the support structure, and onto the stiffback. By raising the stiffback upwardly and securing an end of the pipe with the pin up shoe, the pipe is bent against the segmented bending die. The segmented bending die and the support structure conform to the external surface contours of the pipe to support the walls of the pipe, thereby preventing distortion, buckling, flattening, or collapsing of the pipe during bending.

Abstract: The invention relates to a method for reducing the level of radioactivity of a metal part. To this end, an oxide layer is firstly removed from the metal part by using a decontamination solution. Afterwards, an oxidizing agent which is still present is removed from the decontamination solution. As a result, a layer of the metal is removed. The remaining metal can be delivered to a common scrap yard since radionuclides are only found in the layer of the metal part located close to the surface.

Abstract: A quilt manufacturing facility (100) having a plurality of quilting machines (10) is provided with an automated scheduling system (50) which automatically generates and distributes schedules for the making of quilted products listed in input customer orders. The generated schedules are distributed in the form of computer files downloaded to the controllers (29) of the quilting machines (10). The generation of schedules is carried out by a programmed central scheduling computer (51) which considers stored data identifying each of the machines and their capabilities, the materials available for production of the products and the product specifications, and determines the machine setting and material requirements for each product on the customer order list as well as the required completion times for each of the ordered products. Schedules for each machine are generated so as to schedule each product with other products having similar machine setting or material requirements in a manner that is consistent with the required completion or delivery times for each product. The scheduling optimizes the use of the quilting machines and operator time by reducing the number of machine setups and material changes. Information is collected from each machine which records all downtime of the machines and the reasons therefor and which records a history of the actual performance of the machines for use by the scheduing computer in more accurately evaluating future schedules.
