Title: Stepped dimpled mounting brackets for heat exchangers
IPC: F28D1/03
Filed: 1997-09-11
Abstract: A mounting bracket is disclosed for producing plate and fin heat exchangers of the type having a plurality of stacked, hollow plate pairs or tubes including mating end bosses having communicating openings formed therein to form a manifold for the flow of fluid through the plate pairs or tubes. Fins are located between and at the top end bottom of the stacked plate pairs extending between the end bosses. End fittings are used for the inlet and outlet of fluid to the plate pairs or tubes. The mounting brackets allow the end fittings to be positioned where desired to define different flow circuits through the plate pairs, and also allow different size end fittings to be used, without having to use special spacers, different size fins or specially shaped plates to accommodate the different end fittings. The mounting brackets have a planar central portion and opposed offset end portions located in a plane parallel to and spaced from the central portion. The central portion has spacing projections extending transversely in a direction opposite to that of the opposite end portions. Different fitting sizes are accommodated simply by changing the height of the spacing projections.

Title: Le redresseur lisseur deux en un
Inventor: JULIEN JEAN
IPC: B21D3/14
Filed: 1997-10-31
Abstract: Lorsqu'un poteau ou autre tuyau d'acier est plié, bossé ou tordu, et que l'on désire le redresser ou le lissé, sans chauffer l'acier, il faut recourir au martelage manuel pour le lissage et il faut appliquer une force opposée à la déviation du tuyau pour le redresser. Ces façons de faire sont a la fois peu efficaces, archaiques, donnent des résultats irréguliers et ne sont pas productives à grande échelle. La présente invention a pour idée maîtresse de redresser le tuyau d'acier en appliquant une force mécanique uniforme contre les parois intérieures du tuyau, force suffisante pour corriger les déviations majeures du tuyau tout en effectuant dans la même opération le lissage des bosses, le tout d'une façon simple, rapide et efficace.

Title: Phaselock threshold correction
Inventor: STEPHENS DONALD R
IPC: H04B1/10
Filed: 1997-10-21
Abstract: A noise estimator for threshold correction of a receiver includes a low pass fitter to remove wideband noise from an input signal that includes a signal component and a noise component. The output of the wideband filter is applied to a square-law power detector having an output applied to an envelope detector. The output of the envelope detector is the instantaneous envelope of the input signal and is applied to a low pass filter to perform time averaging and is also applied to a differential network. The output of the low pass filter is a signal representing a time averaged statistical envelope representing the statistical mean of the instantaneous envelope of the input signal. This signal is also applied to the differential network that generates a signal representing the difference in the instantaneous envelope of the input signal and the time averaged statistical envelope signal. This difference signal is applied to a square-law power detector and then to a low pass filter for time averaging. An output of the low pass filter is a signal representing an estimate of the noise component of the input signal.

Title: A method and system for reliable remote object reference management
Inventor: BERNABEU-AUBAN JOSE
IPC: G06F9/44
Filed: 1998-06-29
Abstract: The present invention pertains to a system and method for tracking object references in an object-oriented computing system including a number of independent computing nodes interconnected by a communications link. The reference counting mechanism tracks references to an object through the use of a messaging protocol. A servernode keeps a foreign reference count for each of its objects. The foreign reference count indicates the number of remote nodes having a reference to one of the server's objects. A server node increments the foreign reference count for each object reference that it exports prior to sending it to an intended client node. A client node will send a message to the server node when it has already received the exportedobject reference and in response to this message, the server node decrements theappropriate foreign reference count. When a client node receives an object reference from another client node, the receiving client node will message the appropriateserver node that the receiving client node has a reference to the object. In response, the server node increments the appropriate foreign reference count. The reference counting mechanism utilizes a node failure protocol in order to accurately track the foreign reference counts in light of node failures.

Inventor: EDER ERICH
IPC: B65C3/10
Filed: 1992-07-31
Abstract: Containers are transported on rotatable support plates which are arranged in a circle on a rotating turntable.          The leading edge of a label is adhered to a container as it orbits past a vacuum-type label transfer drum.  A curved guide which is tangential to the cylindrical body of the container as the orbiting and rotating container passes it causes the label to wrap completely around the container.  One of a circular array of heat sealing elements which are rotating with the turntable adjacent each support plate is cammed radially outwardly of the turntable into contact with the region on the container where the trailing end overlaps the leading end of the cable.  This fuses the ends of the labels together.  The cam profile is adjustable in length to keep the time during which the heat sealing member is in contact with the label ends overlap constant independently of the rotational speed of the turntable.
