Granted: 1993-08-10
Abstract: Abstract of the Disclosure A heat exchanger assembly comprises a pair of header members and a plurality of heat transfer tubes passing between the headers members.  The heat transfer tubes are adapted to transfer heat between fins on the exterior of the tubes and a working fluid in liquid or gaseous phase within the tubes.  A pressure drop minimizing tube passes between the headers and has a cross sectional area significantly larger than the heat transfer tubes.   The pressure drop minimizing tube is adapted to carry the working fluid in a gaseous phase either as an inlet, when the heat transfer assembly is utilized as a condenser, or as an outlet, when the heat transfer assembly is utilized as an evaporator.   A member connects the pressure drop minimizing tube at one end to at least two of the heat transfer tubes for condensation to a liquid, when the assembly is utilized as a condenser,  or transferring gaseous working fluid from the heat transfer tubes to the pressure drop minimizing tubes,  when the assembly is utilized as an evaporator.   A plurality of header tubes connect the heat transfer tubes to one another to carry the working fluid through the assembly.   The pressure drop minimizing tube is preferably within the heat transfer tube array and within the fin pattern imposed on the heat transfer tubes.

Title: Apparatus and method for controlling a process using a trained parallel distributed processing network
Inventor: OWENS AARON JAMES
IPC: G06F19/00
Filed: 1990-02-28
Granted: 2001-03-13
Abstract: A parallel distributed processing network, previously trained to simulate a process, is responsive to input activations A to produce outputs Y. The activations are representative of the input parameters P of the process and the outputs are representative of the characteristics C of the product of the process. A set of goal signals G corresponding to the desired physical characteristics D of the product are produced and used to generate a signal representative of the error E between the goal signals G and the outputs Y of the network. The values of the updated inputs AU of the network that ate needed to drive the error E to a predetermined minimum are  determined, and the actual physical input parameters P of the process changed to correspond to the updated inputs values AU producing the minimum error. The present invention can be used in both a batch initialization situation and/or itn an on-going process control situation.

Title: Mechanical expansion anchor
Inventor: WRIGHT RAYMOND L
IPC: F16B13/14
Filed: 1990-04-17
Granted: 1996-09-24
Abstract: An improved, radially expansible shell for use in a  mechanical expasion anchor and an anchoring system including such a shell  in  combination  with a resin grouting mix, in a drill hole of predetermined diameter. The shell includes a plurality of leaf portions having internal surfaces for engagement by a tapered camming plug as the shell is expanded, external surfaces having a maximum diameter less than that of the drill hole, and side edges.  A row of tapered teeth extends outwardly from the external surface of each leaf along one of the side edges thereof.  The distance from the central axis of the shell to the crests of the teeth is substantially equal to the radius of the  drill hole.  The teeth frictionally engage the drill hole wall to retard rotation of the shell and ensure the desired expansion.          When the anchor  is   used  with  a   conventional, two-compartment resin  package,  the  resin components may flow around the shell into the annular space between the external surfaces of the leaves and the drill hole wall.

Abstract: Abstract of the Disclosure:         In a mobile telephone device (10) comprising a serial interface (13b) and subjectable to an aging operation with an aging device (20) connected to the serial interface, a central processing unit (12) delivers a clock signal to an aging jig (25) through an interface unit (13) and the serial interface.  In synchronism with said clock signal, the aging jig supplies particular data to the central processing unit through the interface unit and the serial interface.          The central processing unit receives serial data supplied to the serial interface as received data in synchronism with the clock signal.  The serial data is supplied to the serial interface both during progress of the aging operation and while the mobile telephone device is not subjected to the aging operation.  The central processing unit judges whether or not the received data coincides with the particular data.  When the received data coincides with the particular data, the central processing unit carries out the aging operation.

Filed: 1990-06-29
Granted: 2002-08-20
Abstract: A method and apparatus for extracting information-bearing portions of an input signal from which is calculated a sliding average magnitude difference function (SAMDF). The signal is coupled to three separate data channels. Each channel is logarithmically spaced from the adjacent channel and time and amplitude normalized to generate a data template containing the information-bearing portions of the signal. In addition, a fourth channel is derived from the first three. Sixteen data measurements are taken, four from each of the four channels with three additional data measurements being derived from the energy envelope of the information-bearing portion of the input signal. The 19 total data measurements represent the amplitude normalized envelope of the signal.

Title: Control signal generator for a television system
Inventor: LAGONI WILLIAM ADAMSON
IPC: H04N9/44
Filed: 1990-08-23
Granted: 1995-09-26
Abstract: In a color television system, the color signals produced by a luma-chroma IC are summed to produce a signal representative of processed luminance information not otherwise readily available. Pulses of the summed signal corresponding to retrace blanking pulses contained in the color signals, are stripped away in order to reduce errors when attributes of the summed signal are determined, e.g., by an average detector. The detector provides a control signal for modification of a luminance signal, such as by "white stretch".
