Title: Method and apparatus for lining a pipe with a polymer liner
Inventor: MAINE LESLIE
IPC: F16L55/165
Filed: 1995-03-31
Abstract: A liner (30) of polyethylene is pulled through a die (36) and through the pipe (10) and allowed to revert to the internal diameter of the pipe. The force of pulling is half the yield strength of the liner or less. The die has an entry; an throat and an exit; the entry decreasing in diameter towards the throat and the exit increasing in diameter away from the throat. The liner has a maximum diameter before the die, a minimum diameter in the die and intermediate diameter after the die. The liner bending inwards before first contacting the die at the entry, then continuously bending through its minimum diameter as it passes the throat and then undergoing die swell resulting in said intermediate diameter. The throat is defined by the merger in a continuous curve of a radius joining the entry and a radius joining the exit. The entry is convex between where the liner (30) first contacts the die after bending inwardly and said throat.

Title: Photo-acoustic gas sensor
Inventor: BARAKET MOURAD
IPC: G01N21/17
Filed: 1997-03-17
Abstract: A photo-acoustic gas sensor (1) having a measuring cell (2), a lamp (3), a photodiode (17), a gas-permeable diaphragm (7) and a microphone (6) comprises a device for monitoring correct functioning of the diaphragm (7) and the microphone (6), which is operated in an explosion-protected manner and actively produces in the measuring cell (2) an artificial pressure modulation, which is independent of the presence of gases to be detected and is converted by the microphone (6) into electrical monitoring signals.  The pressure modulation is effected by heating of the air in the measuring cell (2). In a method of evaluating the monitoring signals, the latter are processed and evaluated in a circuit (11), a microprocessor (21) assigning the monitoring signals to preset ranges and determining the function state of the diaphragm (7) and the microphone (6) as well as the microphone sensitivity. Depending on the range to which the monitoring signal is assigned, either a signal for correct functioning of the gas sensor (1) or a fault signal for defects at the microphone (6) and/or at the diaphragm (7) is produced or, in the event of a variation of the microphone sensitivity as a result of long-term drift, a calibration is effected in that gas concentration values are re-calculated and stored in an EEPROM (22).  A preferred embodiment of the monitoring device comprises an electrical heating element (9) consisting of a wire (12), which as a result of modulated heating of the air situated in the measuring cell (2) produces an artificial pressure modulation.  The dimensions of the wire (12) and components of the circuit (11) are selected in such a way as to meet the official specifications regarding maximum current and maximum temperature for explosion protection.

Patent CA-2210755-A1 (CA)
Inventor: YU PAUL KWONG-HUNG
IPC: G06F9/46
Filed: 1997-07-17
Abstract: The invention provides a mechanism for distributing objects from a object oriented framework that permits method invocation and state information notification, such as event notification in a JavaBeans software component model. A code generation tool generates code from an existing server object that contains only application domain specific logic, to support deployment of the server object on a remote machine in a distributed application. The generated code includes a proxy class to reside locally with a client program that might invoke methods on the server object or receive notification of state information (events) from the server object, and a proxy class to be remotely deployed with the server object. The proxies created provide all the middleware specific logics. More importantly, the proxy on the client side contains all of the public methods, properties and event interfaces of the server object, so that a client program using this proxy can invoke the server object's methods and register to receive notification of state information on the proxy as if it were interacting locally with the server object. A proxy on the server side communicates the client program's method invocations and registrations to receive event notifications to the server object as if this proxy were a local client. When an event notification is issued by the server object, it is received by the proxy on the client side which transmits the notification through the middleware of the distributed application to the proxy on the client side. The proxy on the client side overrides the identification of the source of the notification, substituting itself, to receive any requests for data on the state information from the client program, but then delegates such requests to the object containing the state information to be fulfilled.

Abstract: A waveform generator generates a specified exponential function for converting a position signal corresponding to the position on the screen one by one to a corrected position signal thereby obtaining a waveform with shifted phase near the screen center compared to the original waveform. A conversion unit receives a position signal corresponding to the position on the screen one by one or the output of a second addition unit, a first addition unit for adding the output of the conversion means and an offset coefficient, a first multiplication unit for multiplying the output of the first addition unit and a frequency correction coefficient, a second addition unit for adding the position signal P and the output of the first multiplication unit, and a second multiplication means for multiplying the output of the conversion unit by an amplitude coefficient A. The position signal is input to the conversion unit and the first addition unit receives the output of the conversion unit. In the second step, the output of the second addition unit is input to the conversion unit, and the second multiplication unit receives the output of the conversion unit.

Title: Narrow field electromagnetic sensor system and method
Inventor: MCEWAN THOMAS E
IPC: H04B1/7163
Filed: 1996-03-15
Abstract: A narrow field electromagnetic sensor system and method of sensing a characterisitc of an object provide the capability to realize a characteristic of an object such as density, thickness, or presence, for any desired coordinate position on the object. One application is imaging. The sensor can also be used as an obstruction detector or an electronic trip wire with a narrow field without the disadvantages of impaired performance when exposed to dirt, snow, rain, or sunlight. The sensor employs a transmitter for transmitting a sequence of electromagnetic signals in response to a transmit timing signal, a receiver for sampling only the initial direct RF path of the electromagnetic signal while excluding all other electromagnetic signals in response to a receive timing signal, and a signal processor for processing the sampled direct RF  path electromagnetic signal and providing an indication of the characteristic of an object. Usually, the electromagnetic signal is a short RF  burst and the obstruction must provide a substantially complete eclipse of the direct RF path. By employing time-of-flight techniques, a timing circuit controls the receiver to sample only the initial direct RF path of the electromagnetic signal while not sampling indirect path electromagnetic signals. The sensor system also incorporates circuitry for ultra-wideband spread spectrum operation that reduces interference to and from other RF services while allowing co-location of multiple electronic sensors without the need for frequency assignments.
