Title: Electro-optic devices
Inventor: ADAMS MICHAEL J
IPC: G02F1/025
Filed: 1986-10-14
Granted: 1991-03-19
Abstract: ABSTRACT       An opto-electronic device, comprising an optical waveguide and means for imposing an electrical field in a direction transverse to the waveguide, is designed such that the spatial spread of the electrical field is very small.  The electrical field overlies the region of peak amplitude of the profile of optical radiation in the waveguide.     Constructed principally out of semiconductor materials made from elements selected from the III and V groups of the Periodic Table, the device lends itself to monolithic integration in optical communications systems.

Title: Method for demounting of constructions
Inventor: KARHUMAKI MARKKU
IPC: E04G19/00
Filed: 1986-10-28
Granted: 1991-04-16
Abstract: ABSTRACT        A method and apparatus used in the assembly and disassembly of temporary structures required during construction projects.  The apparatus includes a connector element which comprises an elongated channel member having a central groove and substantially flat coplanar flanges along the opposed sides of the groove.  The flanges are provided with integral spikes and/or holes for accepting driven fasteners.  The other component of the apparatus is an inflatable tube which is sized to be accommodated in the central groove or channel and is preferably substantially the same length as the connector element.  In use, the connector element is used to attach together a series of boards or sheets of material suitable for use with driven fasteners.  Concrete forms, barriers and the like are particularly suitable temporary structures for assembly and disassembly in accordance with the invention.  When the temporary structure has served its purpose and is to be disassembled, a pressurized fluid is injected into the inflatable tube which forces the elongated connector away from the building components, thus pulling out the driven fasteners and effecting disassembly of the structure in a very short period of time.

Granted: 1991-01-29
Abstract: Abstract The present invention relates to a barbeque cooking and smoking apparatus.  The apparatus is comprised of a portable frame supporting an oven and a partially vertically offset abutting firebox in a side by side re-lationship.  The oven has an upper portion raised higher than the firebox and a lower portion which is coextensive with an upper portion of the firebox.  The firebox has at least an openable cover in its upper portion with a food supporting grill spaced below the cover in the firebox, and an openable door in a non-abutting side, located for access to a fire holding space below the grill and of sufficient size to admit fuel for a barbequing fire.  The firebox also has an adjustable inlet for combustion air.          The oven has at least an openable door in the upper por-tion, a food supporting grill intermediate the upper and the lower portion and a unit for exhausting gases and smoke from the oven.  A unit is provided for passage of smoke from the firebox to the oven through the abutting sides of the firebox and the oven.  A unit is provided which is responsive to movement of the oven door for closing off the unit for the passage of smoke when the door is open and for opening the unit for the passage of smoke when the door is closed.

Title: Data transformation and clipping in a graphics display system
Inventor: HEMPEL BRUCE C
IPC: G06T11/00
Filed: 1986-11-25
Granted: 1990-01-23
Abstract: ABSTRACT OF THE DISCLOSURE A display processor in a raster graphics display system includes a transformation, clipping and mapping feature which controls the transformation, clipping and mapping of graphics data. A control byte contains 5 bits identified as: M- Window to viewport mapping; P-perspective projection; D-2D/3D mode; T-transformation; and C-clipping. Each bit in the control byte is tested to determine what operations are to be performed on the figure to be drawn. For example, if the D bit is one, indicating a three dimensional figure and the T bit is one, indicating transformation, and the C bit is one, indicating clipping, the P bit determines whether the clipping will be perspective or non-perspective clipping and the M bit determines whether the figure to be drawn is to be mapped to the view port.

Title: Pressure transducer
Inventor: HANLON STEPHEN P
IPC: G01L7/00
Filed: 1987-02-04
Granted: 1991-06-11
Abstract: ABSTRACT           Physiologic pressure transducers convert an applied pressure (e.g., blood pressure) into an electric signal, which can be displayed by a monitor as a numerical value or continuous waveform.  While reusable pressure transducers have been used for a number of years, innovations in solid-state technology have made disposable transducers feasible. In particular, disposal transducers which are impedance matched for use with monitors formally used for reusable transducers are disclosed.  The pressure transducer is rugged due to the careful mounting of the transducer diaphragm and integral compensation circuitry.  In addition, the geometric configuration of the flow path is uniform such that debubbling of the unit is easy.

Title: Two-cycle internal combustion engine
Inventor: NAKAMURA NORIHIKO
IPC: F02B75/02
Filed: 1987-06-09
Granted: 1992-03-17
Abstract: TWO-CYCLE INTERNAL COMBUSTION ENGINE     ABSTRACT OF THE DISCLOSURE     A two-cycle internal combustion engine comprises a cylinder head having an intake port and exhaust port opened to a combustion chamber, to which compressed fresh air is introduced via an intake valve.  The intake and exhaust valves are operated in response to a crank angle.  A pulsation pressure of exhaust gas in the exhaust port is substantially restrained during an idling or light load running condition.  The exhaust valve is opened earlier than the intake valve when the speed of the downward movement of the piston is relatively high, such that a part of exhaust gas in the exhaust port flows back to the combustion chamber in that condition.  An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back and the fresh air is slowly introduced onto the exhaust gas swirl in that condition.

Granted: 1991-12-17
Abstract: ABSTRACT OF THE DISCLOSURE     A process is described herein for the preparation of a ceramic green body by hydrolyzing two groups of alkoxides to form a dispersion of their reaction product, concentrating the disper-sion to a sediment without drying it, and admixing a binder solu-tion, plasticizer and optional release agent with the sediment to make a ceramic slip formulation.
