Title: Prefabricated window for installation in an inclined roof
Inventor: BORRESEN BJARNE
IPC: E04D13/03
Filed: 1990-10-15
Granted: 2000-02-08
Abstract: A bracket for fixing a prefabricated window to roof boards or sheathing in an inclined roof is already secured to the window main frame during the factory assembling of the window. The presecuring of the bracket is effected by a screw inserted through a hole in a positioning member which through a connecting portion consisting of a bridge and a rodlike member is integrally connected with one side edge of a first leg of the bracket. The first leg continues at its lower side into a second leg at right angle to the first leg.      Before packaging the window for transportation the first and second legs are swung into abutment on the main frame by turning around the connecting portion.      When the window is to be installed in the roof the first and second legs are swung through an angle of 180° until the first leg abuts against the positioning member. In this position mounting screws are through the overlapping holes screwed into the main frame. Then the window is secured to the roof hoards by driving screws or nails through the holes in the second leg into the boards.

Title: Method of operating a firing installation
Inventor: KNOEPFEL HANS PETER
IPC: F23D17/00
Filed: 1990-11-28
Granted: 2001-02-20
Abstract: In a fixing installation, fresh air (6) is drawn in and mixed with a fraction of flue gases (7), which are taken from the combustion chamber (1), by means of a fan (5) which acts outside of the casing of the firing installation. The fresh air/flue gas mixture (8) thus formed flows on its way to the combustion chamber (1) through a first heat exchanger (2a) whose caloric preparation is accomplished by the flue gases (7) fed in. In the combustion chamber (1) itself, this mixture flows through a heat exchanger (2) placed there. Before the mixture (9) thus preheated is fed as combustion air to a burner (4), it undergoes a further mixing with flue gases via a number of jet injectors (3), which further increases the temperature of this combustion air (10), with an optimized flue gas fraction.

Title: Process for recovering oil from tar sands
Inventor: GREEN ROBERT C
IPC: C10G1/00
Filed: 1991-10-07
Granted: 2003-06-10
Abstract: A process for recovering oil from tar sands by subjecting the tar sands to aqueous extraction to produce a bitumen-rich layer containing bitumen, water and solids and a bitumen-lean layer containing rela-tively less bitumen and relatively more water and solids. The solids present in the bitumen-lean layer contain a substantial portion of finely divided clay having adhered organic matter. The clay solids are retained with the bitumen from the bitumen-lean layer and the bitumen-clay mixture is pyrolyzed. Pyrolysis of the bitumen-lean layer containing clay having adhered organic matter reduces the volume of aqueous tailings which would otherwise be produced and also results in increased hydrocarbon yields.

Title: Pressure resistant sheet metal end closure
Inventor: MCELDOWNEY CARL
IPC: B65D8/04
Filed: 1992-01-28
Granted: 1996-07-02
Abstract: A sheet metal end closure for a container of pressurized products, which closure includes a substantially planar central panel, a countersink around the central panel, a chuckwall around the countersink and a seaming flange around the chuckwall.  It further includes an annular downwardly stepped portion between the central panel and the countersink and a coined zone in the panel radius which connects the stepped portion to the countersink.  The invention includes a method and apparatus for forming such a sheet metal closure wherein the panel radius between the central panel and the countersink is coined around at least a portion of the circumference of the central panel before the periphery of the central panel is reformed.  In accordance with this invention, a major portion of the central panel is moved away from the countersink by depressing the outer peripheral portion of the central panel along with the countersink and chuckwall.  Depressing the peripheral portions of the end shell with respect to the central panel increases substantially the height of the central panel and uses the slack or loose metal created by the coining operation.  This puts the metal in the end shell substantially into tension and helps reduce, or eliminates, central doming of the end shell due to internal pressure in a container on which the shell is seamed.
Patent CA-2063738-C (CA)
Title: Coin validators
Inventor: WAITE TIMOTHY PETER
IPC: G01B7/06
Filed: 1990-07-27
Granted: 2000-07-18
Abstract: A coin validator (2) has a thickness sensor formed by two coils (10, 12) positioned one on each side of the coin path. The coil outputs are processed separately using a look-up table (20) to derive values which are linearly related to coin position across the width of the passage, using the same constant of proportionality for both sensors. Accordingly, by combining the processed outputs there is derived a value which is independent of coin position and which can be peak-detected to indicate thickness.

Title: Device for aligning and clamping a rail flange
Inventor: GREENHOW DAVID
IPC: E01B9/66
Filed: 1992-04-16
Granted: 1999-12-14
Abstract: A rail clamping device is provided for aligning and clamping the flange of a rail to a support surface. A slotted clip is fitted over an anchor bolt or other suitable connector, a plate cam washer having an eccentric hole is placed upon the clip, and a nut threaded upon the bolt to secure the clip and washer to the rail flange. The clip has a slotted base portion which slidably engages the support surface in a loose condition and bears upon the support surface in a clamped condition. An abutment portion extends from the base perpendicular to the support surface to engage the outer face of the rail flange. A cantilever portion extends forwardly from the abutment portion and has a bottom surface to which a synthetic rubber strip is bonded to engage the upper surface of the flange to clamp the flange to the supporting surface. The cam washer slidably engages the top surface of the base portion in a loose condition. The cam washer has an outer flank for engaging a rearward face of the abutment portion.      Preferably, the cam washer has a spiral cam profile such that the angular rotation of the washer upon the bolt results in substantially proportional lateral movement of the clip and abutting rail flange. The rail flange may be aligned by rotation of the cam washers of devices on opposing sides of the rail when in a loose condition and then clamped securely in place by rotation of the nut.

Tunnels (150, 160) may be provided through the guide element for blindly guiding or aiming other tubular-type members selectively into the esophagous or larynx. A tubular handle (14) or curved blade (454) is connected to the guide element (12) to blindly insert guide element (12) into the throat. Alternative embodiments (310, 350, 410, 450) of medical device (10) are also described.

Title: Blind rivet
Inventor: KRUG JUERGEN
IPC: F16B11/00
Filed: 1992-09-17
Granted: 1996-01-09
Abstract: A blind rivet, especially for the production of rivet connections between load carrying components in aircraft construction, has a rivet shaft or mandrel with a thickened end and a pulling end.  The shaft has a conical section tapering from the thickened end to the pulling end.  Grooves run around at least the conical section.  The rivet mandrel or shaft is axially received in a rivet sleeve with a set head.  Adhesive is provided in the grooves, especially along the conical section of the blind rivet.  The adhesive hardens in the seam or gap formed between the rivet sleeve and rivet shaft when the blind rivet has been set.  This two-component blind rivet has a structural strength equivalent to that of a solid rivet so that it can also meet higher structural strength requirements.  Additionally, the adhesive prevents cold welding between the shaft and the sleeve and seals the gap.

Title: Whooping cough vaccine
Inventor: MOOI FREDERIK R
IPC: C07K14/195
Filed: 1993-01-07
Granted: 2003-11-25
Abstract: The invention relates to acellular vaccines being effective against whooping cough and is based on a functional component of the fimbriae of Bordetella pertussis i.e. the actual adhesin molecule being a "minor" component in the fimbriae. The vaccines according to the invention have the advantage that both they may induce an effective immune respons against all B.pertussis strains and - most likely -also against Bordetella parapertussis being the second important causative agent of whooping cough. Further, the vaccines may also be used for veterinary applications, to protect against Bordetella bronchiseptica infections.
