Title: Heat Transfer Tube
Inventor: GUPTE NEELKANTH S
IPC: F28F1/36
Filed: 1995-10-24
Abstract: A heat transfer tube (10) for use in an application, such as a shell and tube type air conditioning system condenser, in which a fluid flowing through the heat exchanger external to the tubes condenses by transfer of heat to a cooling fluid flowing through the tubes. The tube has at least one fin convolution (20) extending helically around its external surface (13). A pattern of notches (30) extends at an oblique angle (a) across the fin convolutions at intervals about the circumference of the tube. There is a spike (22) between each pair of adjacent notches. The fin convolution, notches and spikes are formed in the tube by rolling the wall of the tube between a mandrel and, first, a gang of finning disks (63) and, second, a notching wheel (66). Because, during the manufacture ofthe tube, ofthe interaction ofthe rotating and advancing tube and the notching wheel, the angle (,B) of inclination of the axis of the tip of the spike is oblique with respect to the notch angle. The maximum width (W,) of the spike is greater than the width (Wr) of the proximal portion of the fin convolution.

Patent CA-2168455-A1 (CA)
Title: Dental restorations
Inventor: PETTICREW RICHARD
IPC: A61C5/77
Filed: 1995-05-10
Abstract: The present invention is connected with a process for the formation of dental restorations from glass-ceramic materials and the resulting dental restorations. In this invention a dental restoration is prepared by placing a glass ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring glass-ceramic material to a working range at temperatures above its liquidus temperature. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range the crucible is heat-pressure deformable without rupturing. Once the glass-ceramic material is heated to its working temperature the crucible is brought into contact with a mold having a preformed cavity therein, the cavity being in the shape of the desired dental restoration.  As the distance between the heated glass ceramic material and the mold is decreased, the crucible is deformed to form a seal with the mold thereby facilitating the injection of the molten glass-ceramic material into the mold cavity. The resulting dental restoration has superior optical esthetic and strength properties. The invention further includes the heat-pressure deformable crucible which is useful in the process of this invention and the related apparatus.

Title: Maximum likelihood sequence estimator and maximum likelihood sequence estimating method
Inventor: SHIINO HARUHIRO
IPC: H04B3/04
Filed: 1996-03-08
Abstract: When a maximum likelihood sequence estimator according to the present invention is used as an equalizer or the like for a receiver, a Viterbi algorithm processing portion 331 in the maximum likelihood sequence estimator estimates a transmission symbol Ean with a reception signal yn and an estimated impulse response {Ehk} corresponding to Viterbi algorithm so as to estimate a maximum likelihood sequence corresponding to a soft decision regardless of a modulating method.  A transmission logic code decoder 34 converts a transmission symbol Ean into hard decision data Ebm with a value "1" or "0".  An envelope detector 333 that is a transmission line quality evaluating means detects an envelope level pn of the reception signal yn.  A soft decision value converting portion 334 converts the envelope level pn received from the envelope detector 333 corresponding to the value "1" or "0" of the hard decision data Ebm received from the transmission logic code decoder 34 so as to obtain soft decision value output data qm.

Abstract: An intelligent circuit interrupt system is electrically connected between an AC source and a load for interrupting a flow of AC from the source to the load upon detection of an interrupt condition. A circuit interrupter electrically connected to phase and neutral terminals of the AC source defines the interrupt condition. A  relay switch with a relay coil and phase and neutral contacts is included such that line and load ends of the phase contact are electrically connected, respectively, between the interrupt means load side phase port and a phase terminal of the load. Line and load ends of the neutral contact are electrically connected, respectively, between the interrupt neutral port and a neutral terminal of the load. The relay coil is electrically coupled between load sides of said phase and neutral contacts for controlling the contacts in response to the interrupt signal. An open-contact miswiring detector (OCMD) is electrically connected to one of the phase and neutral contacts for detecting a miswiring condition when the contacts are in an open state, and a closed-contact miswiring detector (CCMD) is electrically connected to the OCMD and to one of the neutral and phase contacts for detecting a miswiring condition when the contacts are in a closed state. A timing signal generator generates system timing signals. A test circuit electrically coupled to the interrupt means and the timing signal generator tests the interrupt means operability. An alarm circuit is electrically responsive to the test circuit, the timing signal generator, the OCMD and the CCMD for communicating an open-contact miswiring condition, a closed-contact miswiring condition, an operational failure condition, and a need for external testing condition. A power supply is electrically connected between the load ends of the phase and neutral contacts, and to the timing signal generator.

L'invention permet d'obtenir un abaissement des températures de la section chaude (T¿hot?) sans nécessiter de réduction de la charge du réacteur, et améliore le rendement du cycle de conversion électrique de la centrale. Cet avantage s'accompagne de la possibilité de prolonger le cycle de combustible de la centrale en raison d'un meilleur rendement de la conversion électrique. L'abaissement des températures de la section chaude (T¿hot?) permet également de prolonger de manière surprenante la durée de vie du générateur de vapeur. Un autre avantage réside dans la diminution de l'érosion/corrosion de constituants du système secondaire, même des aubes de turbine et des membranes. Le générateur à turbine à gaz utilisé dans cette invention peut également faire office de système de secours ou augmenter la puissance de l'installation lors de pointes de consommation ou en cas d'urgence. L'invention permet en outre de prolonger la durée de vie de la centrale et de réduire les temps d'arrêt dus au rechargement en combustible.
