Granted: 2008-06-10
Abstract: An electric chafer heater for a chafer (10) is disclosed herein. The chafer heater (36, 38) is removably supported by a shelf disposed below a chafing dish. The chafer heater includes a base having a cylindrical bottom portion (52) held within an aperture in the shelf (14) sized for receiving a standard can heater. The chafer heater further include s a resilient member extending upward from the base, and an electric heating assembly coupled to the resilient member opposite the base. The heating assembly has a heating surface posititionable above the base by the compression of the resilient member. The heating surface is biased against the chafing dish when the base is supported by the shelf to provide a thermal interface to transfer heat between the heatin g surface and the chafing dish. The heating assembly has variable (e.g., low and high) power settings selected by an input device (e.g., a switch). The heater includes a ballast at the bottom of the base, and a switch which cuts off the flow of electricity to the heating assembly in response to a sensed parameter (e.g., temperature; inclination).

Abstract: A surface pattern is made up of surface elements (1 to 7) which are arranged in a mosaic-like fashion and which have microscopic relief structures. The surface elements (2 to 6) which are divided at least into first and second surface portions (8; 9) have in the first and second surfac e portions (8; 9) asymmetrical diffraction gratings (12; 13) with an optical diffraction effect, wherein in each divided surface element (2 to 6) adjacen t first surface portions (8) are separated by at least one second surface portion (9).

Title: Narrow spectral width high power distributed feedback semiconductor lasers
Inventor: EARLES THOMAS L
IPC: H01S5/12
Filed: 1999-03-31
Granted: 2005-05-17
Abstract: High power edge emitting semiconductor lasers are formed to emit with very narrow spectral width at precisely selected wavelengths. An epitaxial structure is grown on a semiconductor substrate, e.g., GaAs, and includes an active region at which light emission occurs, upper and lower confinement layers and upper and lower cladding layers. A  distributed feedback grating is formed in an aluminum free section of the upper confinement layer to act upon the light generated in the active region to produce lasing action and emission of light from an edge face of the semiconductor laser. Such devices are well suited to being formed to provide a wide stripe, e.g., in the range of 50 to 100 µm or more, and high power, in the 1 watt range, at wavelengths including visible wavelengths.

Title: Lance-grenades
Inventor: GABLOWSKI JURGEN
IPC: F41C27/06

Granted: 2005-03-15
Abstract: L'invention concerne un lance-grenades rapporté (13) destiné à être monté sous le canon (3) d'un fusil (1) et servant à tirer une grenade (59). Le canon orientable (15) du lance-grenades est monté sur un élément de raccordement (37) qui l'entoure dans une large mesure et présente donc une rigidité suffisante pour ne pas se déformer lorsqu'il est soumis aux contraintes du tir. Par conséquent, les douilles ne sont pas bloquées dans le canon du lance-grenades après le tir, mais peuvent être extraites ou éjectées facilement. De manière avantageuse, il n'est pas nécessaire d'avoir recours une unité d'extraction ou d'éjection, car le tireur saisit la douille vide avec ses doigts à travers des évidements (61) pratiqués sur le côté arrière du canon (15) du lance-grenades et peut ainsi la retirer sans peine.

Abstract: A way of increasing the dynamic range of a mass spectrometer which incorporates a time to digital converter such as commonly used with a time of flight mass analyser 9 is disclosed. A z-lens 4 upstream of the analyser 9 can be switched between a high sensitivity mode wherein a beam of ions 2 passing therethrough is substantially focused on to the entrance slit 10 of the analyser 9, and a low sensitivity mode wherein the beam of ions 2 is defocused so that the diameter of the beam substantially exceeds that of the entrance slit 10 of the analyser 9. Obtaining data in the low sensitivity mode in combination with obtaining data in the high sensitivity mode enable an order of magnitude increase in the dynamic range to be obtained.

Granted: 2009-09-01
Abstract: There is disclosed a method and apparatus for treating produced water from a heavy oil thermal recovery unit to achieve water recovery and recycle levels of greater than 80% and as high as 100% to achieve zero discharge criteria. The method includes the initial steps of capturing the waste heat energy from the high pressure steam separator located downstream of the steam generators. Further, transferring the heat energy into a heated separator and reboiler exchanger to distill oil reservoir produced water and recover distilled water and a concentrated brine or solid product. The heated separator concentrated stream is circulated through the reboiler exchanger to maintain from 1% to about 50% mass vapour in the stream returning to the heated separator and prevent fouling and scaling. A further embodiment unifies the antifouling methodology with SAGD type heavy oil recovery. In another embodiment, a crystallizer is augmented to the circuit for further advantages.

Abstract: This invention is an insufflation system (56) that includes a first tube (62) that inserts into a patient's airway for providing a primary flow of breathing gas to such a patient. At least one insufflation catheter (66) is provided in or within the first tube for delivering a flow of insufflation gas to the patient. In one embodiment, the flow of insufflation gas is delivered in a first direction generally toward the patient's lungs and in a second direction generally opposite the first direction so that the flow in the second direction creates a negative stagnation pressure that substantially cancels out the positive stagnation pressure generated by flow in the first direction. In a second embodiment, an exhaust vent (70) is provided in the first tube for exhausting a flow of gas from the first tube at a rate that is equivalent to the rate at which the flow of insufflation gas is being delivered to the patient's airway, thereby preventing over-inflation of the patient's respiratory system. A third embodiment of the present invention involves a combination of the two embodiments discussed above.

Abstract: A sensing head for providing bi-dimensional and tri-dimensional data determinative of a position and an orientation of a target object is provided. The sensing head combines both a bi-dimensional and a tri-dimensional sensors. General illumination is associated to the bi-dimensional sensor to allow the acquisition of bi-dimensional data representative of the target object. A stripe--shaped laser light output is projected and diffused on the target object and is sensed by the tri-dimensional sensor. Tri-dimensional data is thus acquired. By proper processing of the bi-dimensional and tri-dimensional data, the position and orientation of the target object may be determined without moving the sensor head and without knowing its position and orientation.
