Title: Drying kiln for lumber having improved insulation
Inventor: GOODWIN THOMAS E
IPC: F26B25/08
Filed: 1991-07-03
Abstract: ABSTRACT OF THE DISCLOSURE      A kiln for the drying of lumber utilizing panels attached to the kiln structure.  The attached panels form the interior surface and the exterior surface of the kiln.  The panels have a cavity for the placement of insulating material.  The insulating material is encapsulated in a liquid impervious container thus preventing condensates  from  infiltrating  the  insulating  material.    The isolation of the insulating material from the ambient moist air of the  kiln maintains the  insulating quality  of  the  insulation normally lost due to exposure to moisture laden air and also aids in preventing the corrosive effect of moist insulation in contact with the metal surfaces.

Title: Method and apparatus for sub-span interpolation
Inventor: MINNICH THOMAS
IPC: G05B19/4103
Filed: 1991-08-02
Abstract: A method and apparatus for machine member motion control are provided which reduce position path errors in sampled data motion control systems. Position commands defining locations of a moveable machine member are periodically produced at a predetermined interval as is conventional in sampled data motion control. Intermediate position commands are produced at a predetermined sub-interval less than the predetermined interval in response to a parametric function relating member position and time, the parametric function being continuous through positions defined by the position commands. The intermediate position coordinates are computed as the sum of products of coefficients and coordinates of selected member position commands. To reduce processing time, the coefficients are computed and stored in advance of execution of motion for recall as motion progresses. Where a parabolic function is used to produce intermediate position commands, the sum of products of coefficients and, respectively, past, present and target coordinates are used to compute intermediate positions between the present and target positions.

Title: Machining apparatus
Inventor: BACKHOUSE ANTHONY E
IPC: B23Q15/22
Filed: 1991-12-20
Abstract: Machining apparatus comprises a boom displaceable along spaced rails and a carriage displaceable along the boom perpendicularly to the displacement direction of the boom. A machining station is adjustably supported on the carriage by three adjustment means to adjust a machine head, such as a milling cutter, towards and away from a workpiece disposed between the rails beneath the machining station. Adjustment of the machine head results from inaccuracies in the level of the rails and/or the displacement of the carriage. Variations in the level of the rails and/or carriage are determined by a respective sensor associated with each adjustment means which monitors a reference defined by a planar laser beam. Alternatively one of the three adjustment means between the machining station and the carriage may be replaced by a pivot with the third adjustment means being arranged to adjust the machine head relative to the remainder of the machining station. In an alternative embodiment, the boom is rotatable about a pivot support within a cylindrical workpiece with the machining station mounted on the remote end of the boom and optionally displaceable with a carriage along the boom. The boom is supported at its remote end on the workpiece by wheel units.

IPC: H01H71/52
Filed: 1990-06-27
Abstract: 2060323 9116720 PCTABS00008 This invention relates to a method of manufacturing a circuit breaker. Known methods suffer from the drawbacks of difficult preassembly of the breaker mechanism because it is held together by the housing and also because it is difficult to automate the process because parts need to be assembled along three orthogonally related axes. The above problems are solved by peassembling the movable parts of the circuit breaker (10) between a pair of frame members (42, 89) supporting the unitary breaker assembly (40) without attachments. Other circuit breaker components, attached to the unitary breaker assembly, are also supported in the housing (11) without attachments. A cover (11b) is secured to the housing to complete the circuit breaker. Another version of the invention preassembles the movable parts of the circuit breaker (10') and the stationary contact mechanism (28) and trip coil (31) with the line and load terminals (12, 14) attached, between a pair of supporting frame members (105) to form an operable circuit breaker module (40). The module (40) is in turn supported in a housing (11) without attachments. The circuit breaker module (40) may be tested and adjusted prior to final assembly.

IPC: F02C7/18
Filed: 1992-04-09
Abstract: Abstract of the Disclosure A nacelle cooling and ventilation system for an aircraft gas turbine engine which includes a chin scoop and duct assembly for directing air through the engine bay where it is exhausted into the engine exhaust through an exhaust shroud eductor. The nacelle is enclosed so that effectively all of the cooling air entering the bay leaves the bay through the engine exhaust and is not dumped overboard, thereby adding to the effective thrust of the engine.  An engine oil and generator oil heat exchanger is positioned in the cooling air duct into the bay so that the same air which cools the bay also cools engine and generator oil. The oil heat exchanger includes directional louvers which regulate and keep to a minimum the amount of cooling air and direct cooling air forwardly in the bay so that the entire bay area is cooled, and which can be shut as a f ire control measure . The nacelle includes bay vent doors which are opened in response to a high oil temperature condition or in an engine shut-off condition on ground to provide auxiliary air flow from the bay. The doors are positionable by an actuator but can be disconnected from the actuator to pivot freely in response to a sudden increase in nacelle bay pressure.
