Abstract: A new class of stable dioxetanes bears a polycyclic stabilizing group and aryloxy moiety, the oxygen atom of which is provided with a protective group which can be removed by an enzymatic or chemical trigger admixed with the dioxetane. The polycyclic stabilizing group is preferably spiroadamantane. The group further bears an alkoxy, aryloxy, aralkyloxy or cycloalkyloxy moiety which is partially or completely substituted with halogens, particularly fluorine and chlorine. Proper selection of electron active groups on the stabilizing moiety, the aryl group and the OR group yields enhanced enzyme kinetics, superior light intensity and excellent detection sensitivity in various. assays.

Title: Apparatus for inspecting sealed packages
Inventor: BIERSCHENK PAT
IPC: G01M3/32
Filed: 1998-03-16
Granted: 2003-12-16
Abstract: An apparatus for inspecting sealed packages of product includes a conveyor belt for receiving the packages. An inspection belt contacts the packages and moves away from the conveyor belt a particular distance depending on whether the packages are properly sealed. When engaged by a package with a good seal, the inspection belt is moved a first distance which causes an indicator carried thereon to send a signal which prevents removal of the good package from the conveyor belt. However, when a leaky bag contacts the inspection belt, the inspection belt is moved a second distance which is insufficient to cause the indicator to send a signal. Consequently, the improperly sealed package is removed from the conveyor belt. The inspection belt may be mounted for linear or pivotal movement upon being contacted by the packages carried by the conveyor belt. In addition, a package engaging member can be used to press the packages prior to passing under the inspection belt to facilitate the discharge of air from leaky packages, e.g., pre-squeezing the packages.

Abstract: A method for spectral measurement is disclosed. The method uses a low- resolution grating to disperse light and thereby image a spectrum thereof. The imaged spectrum is converted into a digital electrical signal and is processed in order to enhance the spectral information. The resulting spectral information is analogous to that captured using a higher resolution spectral imager with optical processing of the spectral data. The method is equally applicable to enhancing resolution of spectra captured using high resolution spectral imaging devices.

Abstract: An electric water heater is provided with simplified phase conversion apparatus including a terminal structure having replaceable line lug portions which are wired to a single phase row of multi-pin connector sockets by single phase routing circuitry, and to a three phase row of multi-pin connector sockets by three phase routing circuitry. Electrical supply wires from sets of fuse holders connected to multiple thermostat/heating element sets are grouped and connected to associated multi-pin connector plugs. To ready the water heater for single phase operation, the plugs are connected to the single phase row of sockets, and to convert the water heater to three phase operation the plugs are simply disconnected from the single phase sockets and connected to the three phase sockets. In this manner the necessity of individually repositioning all of the fuse holder wires on the terminal structure to change from single to three phase operation, or vice versa, is eliminated.

Abstract: The present invention relates to a drill string diverter apparatus for reducing surge pressure when lowering a liner into a partially cased wellbore. The diverter apparatus is connected in a pipe string above a liner being lowered into a wellbore. The diverter apparatus comprises a tubular housing with ports defined therethrough to communicate and redirect fluids received in the liner to the annulus between the diverter apparatus and casing previously set in the wellbore.      The diverter apparatus has an open position whereby the ports are open and communication is established and a closed position whereby flow through the ports is prevented. A sliding sleeve is disposed about an outer surface of the tubular housing and engages the casing. The sleeve moves vertically relative to the tubular housing once the diverter apparatus has been lowered into the casing to selectively open and close the flow ports. A J-slot means is provided for locking the diverter apparatus in its closed position. The diverter apparatus includes upper and lower locking elements which will engage the J-slot when the diverter apparatus is moved to its closed position to prevent relative movement between the sleeve and the tubular housing.
