Filed: 1993-04-23
Abstract: 2133307 9322655 PCTABScor01 A scanning system (10) for inspecting a surface (16) including a light source (30) which generates a beam of light (32) that is reflected, scattered or causes fluorescence at the surface to be inspected. An optical interface (14) receives the beam of light and directs it along a predetermined path extending to and from the surface. An acousto-optic tunable filter (34) tuned to pass light having a wavelength corresponding to a known optical property of a predetermined material is positioned within the path of light.  A detector (42) is positioned to receive light emanating from the surface and is configured to monitor the intensity of light at each predetermined wavelength being monitored and generate a corrsponding signal. The system is preferably attached to a scan board (90) thereby enabling the system to be used in scanning a surface. The system also includes a signal processor (22) which processes the signal generated by the detector. The resulting data is displayed by an output device (26).

Title: Security monitoring system
Inventor: HAY DEREK W J
IPC: H04N7/18
Filed: 1995-02-28
Abstract: A surveillance system is used for monitoring an area with a video camera coupled to a video recorder. A passive infrared detector is used for detecting the presence of a person in the area being monitored. A signal from the detector is used to start the recorder. The recorder remains on as long as a person remains in the area. A timer circuit stops the recording when the monitored area has returned to a normal condition. This system does not require the recorder to be in a constant record mode and thus allows the use of conventional video recorders an relatively short tapes while providing a full record of activity in the area monitored.

Title: Internals for distillation columns including those for use in catalytic reactions
Inventor: YEOMAN NEIL
IPC: B01J8/00
Filed: 1993-10-12
Abstract: A reaction with distillation structure (11) utilizes a plurality of distillation trays (12) and catalyst containers (18) which provide a catalytic reaction zone and a primary flow path for descending liquid streams. Catalytic reaction of the liquid streams within the catalyst reaction zone formed in the containers occurs concurrently with fractiona-tion of the reaction products on the distillation trays (12). The containers (18) may ex-tend continuously through the reaction zone of the distillation reactor (10) to allow for dump loading and removal of the solid particulate catalyst. Alternatively, the catalyst containers may extend from one tray toward a lower tray without passing through the latter. Structure (11) may also be provided within the containers (18) to influence sys-tem hydraulics through the accumulation of liquid within the catalyst bed. This is done by providing an open area (147) interiorly of the catalyst bed (32) into which liquid on the distillation tray is driven. This open area (147) communicates with a liquid accu-mulation zone (149) wherein liquid accumulates until a sufficient liquid head drives the liquid generally horizontally outward, through the catalyst bed.

Title: Methods and apparatus for preparing and delivering bone cement
Inventor: KAPEC JEFFREY
IPC: B05C17/01
Filed: 1994-04-06
Abstract: Methods and apparatus (100) are set forth for preparing and delivering bone cement from a powdered polymer component and a liquid monomer component by simultaneously injecting the powdered and liquid components, stored in separate component chambers (102, 103) into an evacuated mixing chamber (123) under the effect of the vacuum; by uniformly mixing the components in the mixing chamber (123) (to thoroughly wet the powder); and by delivering the cement formed by the polymerization process, as needed in an operative setting, utilizing a single ready to use device.  The uniform mix is achieved by simultaneously subjecting the contents of the component chambers (102, 103) to the effects of the mixing chamber's (123) vacuum via separate one way nozzles (114, 115) interconnecting the component chambers (102, 103) to the mixing chamber (123), which cause the powder to be broadcast and liquid to be sprayed into the mixing chamber (123).  The nozzles (114, 115) are designed and oriented in a predetermined manner (depending on the typed and quantity of the constituent bone cement component  being mixed), to cause the components to interact at a preselected distance within the mixing chamber (123), to assure uniform powder saturation and a thorough mix which yields a homogeneous reaction product.

Title: Gas fade resistant ultraviolet additive formulations for polyethylene
Inventor: GRAHAM BLAIR ALFRED
IPC: C08K5/00
Filed: 1995-01-13
Abstract: A polyethlylene composition for use in fabricating films, agricultural films, molded articles, sheets, fibers, and other articles, where resistance to ultraviolet degradation and color formation is achieved.  The polyethylene composition will include a polyethylene, tris-(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate, or an alpha tocopherol as a primary antioxidant, one or more polymeric hindered amine light stabilizers, and optionally one or more secondary antioxidants and one or more acid neutralizers.  The excellent UV stability and gas fade resistance (resistance to color formation from gases) is achieved by the above combination; however, the result is unexpected because the primary antioxidants have melting points above the compounding temperature of polyethylenes. This would be expected to create uneven dispersion of the antioxidant, resulting in variable product performance. However, the combination gives consistent and excellent UV and gas fade resistance.
