Abstract: HIGH EFFICIENCY GAS BURNER ASSEMBLY                       ABSTRACT          A high efficiency linear gas burner assembly having a mixture manifold assembly for delivering a combustible gas and air mixture to a burner.  The mixture manifold assembly supports an elongate, channel-shaped, secondary air plenum which receives therein a burner housing.  The burner housing supports two, spaced, parallel plates, each having apertures therethrough.  The gas/air mixture is delivered through the mixture manifold assembly and secondary air plenum to the burner housing where the mixture passes first through the apertures of the lower plate, then between the plates, then through the apertures of the upper plate or burner surface. The size and number of apertures in the upper plate and the space between the plates ensures that the flame remains stable during a wide range of turndown, and that the flame does not retrogress through the burner apertures.  Secondary air ports are provided along the interior of the secondary air plenum to provide additional air for combustion.

Title: Method and an improved apparatus for separating solid particles from a liquid
Inventor: STEDFELDT HANS
IPC: B01D29/62
Filed: 1990-05-25
Granted: 1997-03-18
Abstract: An improved method for separating solid particles from liquids, such as dewatering and thickening of sludge collected in a container (1), involves the use of at least one drainage unit (9) having doubled screened jacket walls (25, 26) defining a dewatering chamber (10). The liquid relieved of solids within the chamber is subjected to a turbulent motion acting against said screened jacket walls for obstruction of the solids deposition at the wall surfaces of the chamber facing the sludge in the container. The turbulent motion is obtained by a forced fluid F introduced in the chamber through one or more tubes (30, 31). The fluid may favourably be in form of compressed air or water returned from the reject system (14, 16).

Granted: 1998-06-02
Abstract: There    is    disclosed    an    interference spectrophotometer which collects data while monitoring the position of a movable mirror by providing quadrature control to  accurately  perform coherent  addition  of  data.   The spectrophotometer includes a main interferometer, a control interferometer, a sliding controller controlling movement of the movable mirror, an A/D converter converting analog data obtained by the main interferometer into digital form, a register for holding data obtained by   one scan of the movable mirror, a memory for accumulating data obtained by numerous scans of the movable mirror, an up/down counter receiving the output signals from two detectors included in the control interferometer, and a decision part.  When the counter's value varies, the counter causes the A/D converter to perform its A/D conversion.   Then, the decision part checks the counter's value after the A/D conversion.   If this value differs from the count value obtained prior to the  A/D conversion,  the  data  held  in  the  register  is discarded.

Abstract: An automated retail point-of-sale machine is disclosed having the ability to allow consumers to check out their purchases with a minimal of direct human assistance. The machine is designed to work with products whether labelled or not with machine readable bar codes. The machine possesses security features which deter customers from fraudulently bagging items by comparing the weight changes on the packing scale with the product number related information in the case of labelled products. In the case of nonlabelled products, experienced customers can identify the product through a series of menu choices while beginner customers can allow the supervisory employee to enter a product number abbreviated code, with additional visual and/or dimensional sensory information of the contents being relayed to a supervisory employee. The machine allows high shopper  efficiency by minimizing customer handling of products by positioning the packing scale adjacent to the scanner and typically not requiring further handling of the purchased items until checkout is completed.

Title: Apparatus and process for oil decontamination

Granted: 1999-12-21
Abstract: An apparatus and process for the decontamination of oil such as lubricating, seal, hydraulic or transformer oil, contaminated by gaseous and/or volatile liquid contaminants such as light hydrocarbons, acid gases and water. The apparatus comprises a jet compressor (11) combined with a residence time chamber (12) wherein the contaminated oil is intimately mixed with air or inert gas from a source (19) at elevated temperature, whereby heat and mass transfers occur and the contaminants transfer from the oil phase to the gas phase. The mixture is then flashed into a disengaging drum (14) whereby the gas separates from the oil such that the gas is 95 - 100% saturated with contaminants. This gas is vented, taking with it the volatile contaminant liquids and gases and the decontaminated oil is returned to the reservoir (1) from the bottom of the disengaging drum (14).
