Title: Intelligent computer integrated maintenance system and method
Inventor: CORNETT RICKEY R
IPC: G06Q10/08
Filed: 1991-06-05
Abstract: An intelligent computer integrated maintenance system and method may be used with a group of machines which require maintenance, known as a "complex", such as a group of production lines each of which includes many production machines for producing a product.  The intelligent computer integrated maintenance system includes an electronically stored parts manual which contains a hierarchical listing of all parts in the production machines.  The hierarchical listing contains a complete bill of materials which breaks each machine into subassemblies and breaks each subassembly into its subassemblies down to the level of individual parts.   The intelligent computer integrated maintenance system also includes a maintenance operations computer controller which includes a maintenance schedule management subsystem, an engineering change control subsystem, a parts manual management subsystem and a spares inventory management subsystem. The maintenance schedule management subsystem obtains a schedule of actual and planned production system and groups maintenance activities in order to minimize the lost production time for each complex.  For example, maintenance is scheduled for off-line times for each complex if possible. Alternatively, if a number of maintenance tasks are scheduled for a short time interval, they may be grouped together so that they can be performed simultaneously.           The engineering change control subsystem integrates engineering change activities with maintenance activities to maximize production time. The automated parts manual is also updated to account for engineering change controls.  The spare parts inventory management subsystem orders spare parts based on predicted maintenance rather than on prescribed inventory levels.  Just-in-time parts ordering is thereby facilitated.          The computer integrated maintenance system and method of the present invention allows maintenance operations to be integrated into the complexes primary activity, such as production, in an intelligent manner. When used, production efficiency is maximized as is the use of available maintenance manpower.  Engineering changes are easily accommodated and spare parts inventory is kept to a minimum.

Title: Butterfly-type check valve
Inventor: BALL LARRY K
IPC: F16K27/02
Filed: 1990-06-05
Abstract: A butterfly-type check valve (30) employs a secondary check valve (38) that is carried on the valve plate (36). The valve plate (36) is revolvable and translatable relative to the pivot shaft (34). In operation, the check valve (30) opens in response to a change in aerodynamic forces which act on the valve plate (36), the change being effected as a response to the opening of the secondary check valve (38). As the valve plate (36) rotates to an open position, its revolutionary movement relative to the shaft (34) changes the location of pivot points (40) relative to the surface (62) of the plate. This changes the areas (42, 44) of the surface (62) on both sides of the pivot points (40) so that the aerodynamic forces cause the valve (30) to open still further.

Patent CA-2066177-A1 (CA)
Inventor: HUGHES TIMOTHY C
IPC: G11B27/30
Filed: 1990-11-06
Abstract: Method and apparatus are provided for developing a digital timing signal (HEAD SYNC) indicative of when a head (R1) of a helical scan recorder (30) is positioned over a recorded stripe on magnetic tape (32). The method involves rotating a drum (36) upon which a head (R1) is mounted while the magnetic tape (32) is transported past the drum (36) at a speed greater than the nominal speed at which stripes were recorded on the tape (32).  Given the geometry of the system and format of the tape (32), the head (R1) is eventually able to recognize a pattern of digital data.  The timing of the recognition of the pattern of digital data is used to determine the precise time, relative to each rotation of the drum (36), that the head (R1) ceases to traverse a stripe and the precise time during each rotation of the drum that the head (R1) begins to traverse a stripe. The determination of the edges of the digital timing signal (HEAD SYNC) is repeated upon every rotation of the drum (36). A servo timing signal (SERVO SYNC) for a servo head (S) (also mounted on the drum (36)) is generated in ninty (90) degree phase relationship to the digital timing signal (HEAD SYNC).

Inventor: MATOBA HIROTSUGU
IPC: G11B21/08
Filed: 1992-07-27
Abstract: An optical recording medium driving apparatus has the first high-pass filter for outputting a low frequency component removed signal by removing a low frequency component from a reproduction signal varying depending on a reflected light beam from the optical recording medium. The low frequency component removed signal changes due to transient response just after an access operation starts. Zero voltage is inputted to the second high-pass filter during a tracking operation while a voltage having a negative polarity which is substantially the same amplitude as the AC component of the low frequency component removed signal is inputted to the second high-pass filter.   The first high-pass filter has the same time constant as the second high-pass filter.   Just after the access operation starts,  the negative voltage has the same transient response as the output of the first high-pass filter.   The output of the first high-pass filter is compared to the output of the second high-pass filter in order to have a binary signal of the binary logic condition.   A land is discriminated from a groove according to the binary signal, thereby enabling to access a target track in accuracy.

Title: Immersion-combustion heating liquid device
Inventor: LI WEICHENG
IPC: F24H1/10
Filed: 1992-12-04
Abstract: ABSTRACT     An internal heating device for heating liquids whose heat source is combustion, is composed of a barrel-shaped heat-preserving mainbody, a combustor and a foaming plate installed inside the mainbody, a proportioning pump supplying fuel and air. When it works, the combustor and the foaming plate are thoroughly immersed inside the liquid to be heated, the high-temperature gas creted by the combustion inside the combuctor is divided into a great quantity of bubble by the foaming plate, the bubbles penetrate and rise within the liquid and participate in the heat-exchanging process.    Because the combustor is thoroughly covered by liquid and heat-preserving layer except for a few pipes, there is only few passage to lose heat outwards, and the heat is exchanged dynamically on the large area between the gas and the liquid without the heat-exchanger and its heat loss, therefore this heating device has three virtues: the heat loss outwards is low, the internal heat exchanging efficiency is high, and the structure is simple.

Title: Two-wire multi-channel streamer communication system
Inventor: ROUQUETTE ROBERT E
IPC: G01V1/22
Filed: 1993-01-19
Abstract: For use with marine seismic streamers, a two-wire, multi-channel communication system capable of handling the high throughput necessary for effective communication between a central controller aboard a tow vessel and the many sensors deployed along the streamer.  The central controller includes an intelligent modem with the capability of transmitting and receiving frequency-modulated message signals on one or more signal lines, such as conventional twisted-pair wires, over a number of individual inbound and outbound frequency channels.  In the preferred embodiment, seventeen channels are spread over a frequency band ranging from about 20kHz to 100kHz, thereby making available for communication a bandwidth much wider than available in conventional single-channel streamer communication.  In this way, many positioning sensors, such as compasses, depth sensors, cable-leveling birds, and acoustic-ranging transceivers, attached to the streamer and each having a transmitter and receiver tuned to one of the modem's inbound and outbound channels, respectively, can be put in communication with the modem.  To take advantage of its high throughput capability, the intelligent modem refers to a stored table of individual sensor parameters, such as sensor type, transmit channel, and receive channel, to schedule an efficient scan of the sensors.  As a diagnostic tool, the communication system also monitors the quality and performance of the communication link by measuring and recording such parameters as the transmitted and received signal strengths, signal-to-noise ratios, and number of incorrectly received messages.
