Title: Cereal cooker control method and apparatus
Inventor: MCCULLOUGH NANCY J
IPC: G05D7/06
Filed: 1994-08-03
Abstract: A control process and apparatus enable operation of a pressurized continuous cereal cooker and discharge auger with decreased steam utilization. An electric motor advances the cooked cereal mass through a pressurized zone comprising a quick-opening valve, preferably a butterfly valve. The current drawn by the electric motor is monitored to sense the accumulation of cooked cereal mass at the valve. A process signal, representative of the current drawn by the motor, is compared to a reference signal, representative of a selected value representative of a current higher than that required to turn an empty auger.      A control signal based on the comparison of the first signal and the reference signal is then generated to open or close the valve in response to the control signal. When the process signal drops below the reference signal, the valve is closed.

Abstract: An apparatus for near vertical laying of pipeline offshore.  A support frame and movable deck on a lay vessel support a tower at the desired angle for pipe laying.  The tower has a travel block that is movable between open and closed positions for receiving a pipe section and supporting the weight of the pipe or pipeline.  The travel block is adapted for movement along the length of the tower for raising or lowering the pipe and pipeline.  A pedestal that is movable between open and closed positions for receiving a pipe section and supporting the weight of the pipeline is positioned near the bottom of the tower and adapted to transfer the weight of the pipeline from the travel block to the pedestal without the need to open the travel block.          A strongback with adjustable clamps is used to grasp a pipe section from a ready rack and transfer the pipe section into the tower for addition of the pipe section to the pipeline.  The strongback is guided into and up the tower by rails.  A stinger extends down from the lower end of the tower and is provided with clamps to grip the pipeline during operations.  The main portion of the stinger may be pivoted up adjacent the lay vessel when pipe laying operations are not in progress.

Title: Instrument Probe Having a Back-Lighted Camera
Inventor: LINVILLE GREGORY
IPC: E21B47/00
Filed: 1994-04-04
Abstract: An instrument probe (10) contains an improved camera and light source  arrangement. The light source (18) is positioned behind the camera (22) for providing indirect illumination of a passage being inspected by the camera (22) such as the contents of a bore hole (28) or its casing (36). The light source (18) is physically separated from the camera (22) thus providing insulation to the camera (22) from heat produced by the light source (18). The camera housing comprises a quick connect and disconnect latch (60) which allows for the swift changeover of camera components at the distal end of the instrument probe (10). A parabolic reflector (34) at the light source directs light distally to the instrument body (10). A second reflector (58) is located on the camera body to further reflect light towards the walls of the passageways, thereby enhancing the indirect light funneled to the area being inspected by the camera (22).

Title: Integrated optical isolator
Inventor: CHENG YIHAO
IPC: G02B6/34
Filed: 1995-04-10
Abstract: An integrated optical isolator arrangement is described that is capable of isolating an input optical signal and coupling a pump signal. The coupler includes a pair of lenses with an isolator disposed therebetween. The isolator is sandwiched between a splitter/filter and a wavelength selective device. An end face of each lens has an input and an output port for receiving and transmitting optical signals. The splitter/filter is selected to transmit some of the input signal on a first input port and to reflect the remaining untransmitted portion of the input optical signal to a first output port proximate to the first input port. The wavelength selective device allows the input signal from the first input port to pass through it to a second output port, and in addition, reflects a pump signal transmitted on the second input port to the second output port for combination with the input optical signal.

Abstract: ABSTRACT         A system for integrating an object-oriented application program with relational database management systems. The system utilizes a semantic meta-model repository stored in a relational database to capture the object model of an application program. The system provides code generation of Smalltalk or persistent C++ classes and the code generation permits repeated regeneration to accommodate changes to object model without loss of developer written code in the application program. The system features object modelling including aggregation, containment, and n-ary associations. The system also includes a graphical user interface which provides a front-end modelling interface to the resident repository of the relational database management system.

Title: Light-tight and physically protected packaging for a roll of photosensitive web
Inventor: SPECOGNA VALTER
IPC: G03B27/58
Filed: 1995-04-27
Abstract: Light-tight packaging (10) for photosensitive web roll (R) has a flexible material portion (24) detachably attached to a leading end portion (18) of the roll (R) that over wraps the outermost first convolution (20) of the roll (R).  Opaque end members (22) are attached to annular faces (12,14) of the roll (R).  First, second and third stretchable segments (28,30,32) of the flexible material portion (24) having widths wider than or equal to the length of the roll overlap the outermost first convolution (20) of the roll (R) to form successive outermost convolutions comprising the respective stretchable segment.  Alternate stretchable segments overhang the end peripheral edges (16) of the roll (R) and overlap and compressively seal the end members (22) to the annular faces (12,14) of the roll (R).  Folded overlapped portions (36,40) on the annular faces (12,14) form a labyrinth-type seal (42) on the annular faces (12,14) which cooperate with the compressively sealed opaque end members (28) to resist the ingress of light to the roll (R).  In an alternative embodiment, a cushioning layer (112) is provided on anyone of the sequentially stretchable segments for absorbing shock and abrasions during web roll handling.

Title: Method and Apparatus for Testing the Effectiveness of an Air Barrier Installation
Inventor: KNIGHT KEVIN DUDLEY
IPC: G01M3/12
Filed: 1995-05-08
Abstract: A method and apparatus for testing the effectiveness of a building air barrier, or part thereof, whereby an identification of any air leakage therethrough is provided. A soap solution (or other solution having a similar bubbling characteristic) is applied to a selected air barrier test area. An open-ended flask is positioned over the test area and a centrifugal (or standard) fan is activated at the head of the flask to create an air pressure differential across the air barrier. In the presence of the air pressure differential the soap solution will bubble if there is an air leakage in the air barrier within the test area and, therefore, the existence or non-existence of bubbles in this area identifies whether or not there is an air leakage (i.e. break) in the air barrier in that area.
Patent CA-2149463-A1 (CA)
Title: Class Library for Use in Graphics Programming
Inventor: EICK STEPHEN GREGORY
IPC: G06F9/44
Filed: 1995-05-16
Abstract: A library of C++ classes for use in writing data visualization  programs. The library embodies a general design principle for class libraries: that the classes are partitioned into entity classes and functionality classes.  Entity classes in the library specify properties of areas in a display and the functionality classes specify functionalities which the areas may have, for example,  being responsive to the mouse or the keyboard or being capable of executing drawing commands.  The classes are narrowly defined, and when the C++ programmer specifies a class for an object, he or she can give the object exactly the desired properties by selecting from among the area classes and the functionality classes.  Because properties are acquired by inheritance, code generated using the libraries is shorter and faster than code generated using conventional class libraries.

The cavities when filled with molten solder are covered by a suitable element such as a flexible belt (52) or roller. The molten solder within the covered cavities is then cooled below its solidification point and the covering element removed. If desired, part or all of the solder resist layer (16) or layers (16, 17) may then be stripped from the board (12) to leave solder pads extending above the surface of the board (12).
