Title: Control and method for operating a vaporizer burner
Inventor: REISER PETER
IPC: F23N5/24
Filed: 1989-04-12
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE    Formerly unpleasant blue smoke was generated in a vaporizer burner for auxiliary heaters for motor vehicles once the fuel supply was cut off and the flame died down, as the remaining fuel was merely heated up, but not burnt.  According to the invention the glow plug is activated for a determined period of time during the after-running phase of the combustion air blower.   By this means practically all remaining fuel is vaporized and burnt and therefore the forming of blue smoke and remaining residues in the area of the plug muff and/or the burner is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of making an upholstered element wherein a cover is introduced into a mold to which it tightly adheres.   The mold is closed by means of a first  lid,  following  which  a  soft-foam  reaction mixture is introduced into a first hollow chamber of the mold closed off by the first lid.  At the end of the reaction, the soft-foam reaction mixture fills the first hollow chamber and  forms a soft-foam body. Subsequently, the first lid is removed from the mold and replaced by a second lid,  the soft-foam body remaining in the mold.  Between the soft-foam body in the mold and the second lid, a second hollow space is formed.  Subsequently, a rigid-foam reaction mixture is introduced into the second hollow chamber, which at the  end of  the reaction  fills  the  second hollow chamber and forms a rigid-foam body.

Title: Variable ratio beam splitter and beam launcher
Inventor: DURELL WILLIAM E
IPC: G02B27/28
Filed: 1989-07-10
Granted: 1993-09-28
Abstract: VARIABLE RATIO BEAM SPLITTER AND BEAM LAUNCHER            Abstract of the Disclosure A continuously variable ratio beam splitter and beam launcher for dividing an input light beam, particularly a polarized coherent light beam, into two output beams, within a broad intensity variation range between the beams which may approach zero to 100%, without loss of polarization, comprises an optical array on a support adjustably mounted on a frame; the optical array includes an optical divider aligned with a penta prism that effectively couples the optical divider to one side surface of a right angle output prism.  The optical divider and the output prism launch two output beams, based on division of the light from the input beam impinging on the optical divider.  Variation of the intensity ratio of the output beams is accomplished by rotating the optical array support about a pivot point aligned with the input beam so that the input beam strikes the optical divider at different angles.  Each output beam is picked up by an optical fiber or like transmission element previously located at a fixed position on the frame of the device.  The output beams are always aligned along essentially the same output paths, regardless of changes in the angular orientation of the optical array, so that the amplitude ratio between the two output beams can be changed merely by rotational adjustment of the optical array without refocusing or adjusting other components of the device.

Title: Process of refining saccharide crystals during food processing
Inventor: MARTIN ROBERT A JR
IPC: C13B50/00
Filed: 1989-08-01
Granted: 1995-03-28
Abstract: In an improved process for producing food products, such as confections, including milk and dark chocolate, a crystalline saccharide such as sucrose, and a fat such as cocoa butter, are blended with a minor amount of water. The blend is refined, such as by passing it through the nip of at least one pair of refining rolls, to produce particles having a size less than about 50 micrometers. The minor amount of water is effective to dissolve saccharide particles having a size less than about five micrometers.  Subsequently, the refined product is heated and agitated to remove the minor amount of water.  The resulting semi-processed food ingredient is useful for producing food products having improved viscosity characteristics.

Abstract: ADUSTABLE SPACERS FOR SUPPORTING FRONT WINDOW GLASS IN AN AUTOMOBILE                              ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for mounting a front window glass panel within an automobile vehicle frame. Spacer elements are mounted to the vehicle frame and support the glass panel at a desired position both vertically and laterally. The spacer elements have a vertical support surface and a lateral support, both of which can be integrally adjusted so as to be brought into contact with the window glass panel. A generally H-shaped molding is disposed on the bottom of the front window glass panel and receives the lateral support portion of the spacer element. The width of the lateral support element is less than the width of the opening within this molding so as to provide a clearance between the two that will allow variations in the lateral positioning of the front window glass panel. The spacer element is a one-piece plastic molded item that allows rapid assembly of the front window glass to the vehicle frame.

Abstract: INFLATABLE PACKERS AND METHODS OF UTILIZATION                ABSTRACT OF THE DISCLOSURE        Modifications are provided for both single unit and dual unit inflatable packers or bridge plugs permitting such inflatable tools to be inserted in a well through the primary tubing string which in turn is suitably sealably anchored in the well above the producing formations.  The inflatable tool is inserted into the well on a conduit, such as coiled tubing, and fluid pressure transmitted through the conduit is utilized to effect the expansion and setting of the inflatable elements of the inflatable tool.  The conduit is connected to the inflatable tool by a fluid pressure operated release mechanism and, following the inflation of the inflatable element or elements, the conduit may be utilized to supply treatment fluid or cementing fluid to a formation isolated by the inflatable tool.  Alternatively, the conduit may be disconnected from the inflatable tool and retrieved from the well to permit the inflated tool to maintain a production formation in an isolated condition, to prevent further leakage of a leaking packer, or to permit wireline installation of a choke to regulate the amount of flow into or out of a producing or injection formation isolated by the inflated tool.

Abstract: Solutions of aminomethylenephosphonic acids derived from diethylenetriamine and containing diethylenetriaminepenta(methylenephosphonic acid) as a principal Component are commercial products useful as metal sequestrants. Known solutions, which usually contain not more than 9% by weight of hydrochloric acid, show a tendency to deposit solid aminomethylenephosphonic acid on storage. This tendency is overcome by increasing the mineral acid content of the solution to 10% or more of hydrochloric acid by weight of the solution or an equivalent amount of at least one other non-oxidising mineral acid.

Date Sep. 26, 1985.According to the invention a piezoelectric crystal, e.g. a quartz crystal, coated with a metal or another suitable material is exposed to the action of a corrosive liquid, preferably by being immersed therein. The mass change on the crystal surface, caused by the corrosion, and the resulting change in the natural oscillation frequency of the crystal is determined and constitutes a measure of the corrosivity of the liquid. The natural oscillation frequency of the crystal can in this way also be measured in situ in the liquid, in which way the dynamic course of the corrosion reaction can be followed continuously. According to a special embodiment of the invention the sensitivity during the measurement can be increased, if the crystal is pretreated by being activated with a sulphide solution.
