Abstract: Abstract Of The Disclosure A burner apparatus for burning hydrocarbons.  The apparatus comprises a body defining a plurality of nozzle ports therein, each port facing in a different direction, a discharge nozzle disposed in each nozzle port, and a water ring assembly disposed around the body.  Each nozzle is held in place by a retainer such that a first gap is defined therebetween, and a retainer nut is attached to the body adjacent to the retainer such that a second gap is defined between the retainer and the nut.  This second gap acts as an air discharge orifice and is in communication with an air passage defined in the body.  The water ring assembly comprises an outer ring and an inner ring which combine to define an annular water chamber therebetween.  The water chamber is in communication with a plurality of notches in the outer ring which act as water discharge nozzles for directing a water stream toward the burning petroleum and air stream discharged from the apparatus.  The notches are fully exposed when the water ring assembly is disassembled, thereby making cleaning of the notches a simple matter.  The body is pivotally connected to petroleum line by a swivel fitting.  The apparatus may be locked in any pivoted posi-tion with respect to the petroleum line.

The precipitated alkali metal sulphate is contacted with a saturated  water solution  of alkali metal sulphate  whereafter   neutral  alkali  metal  sulphate  is precipitated and dissolved in water. The  water solution is brought  to  an  electrochemical  membrane  cell  in  which sulphuric acid  is  formed  in  the  anode  compartment and alkali metal hydroxide in the cathode compartment.

Title: Control system for washing machine
Inventor: JANUTKA WILLIAM J
IPC: D06F39/08
Filed: 1992-07-22
Abstract: ABSTRACT      A washing machine controls system employing a thermistor at the inlet valve which enables integration of flow temperature in the valve with time to limit the thermal energy input of water.  In another mode, fuzzy interference logic is used to automatically determine wash time based on signal inputs from a water turbidity sensor and a water fill/load sensor.  The water fill/load sensor also enables automatic fill to the minimum water level needed to wash a given load of clothes.  Fill load sensing employs sensing the reflection of either an ultrasonic or audible acoustic signal from the clothes as the tub is filled.
Patent CA-2074769-A1 (CA)
Title: Formula processor
Inventor: REED DAVID
IPC: G06F7/00
Filed: 1992-07-28
Abstract: A formula processor which computes results for a group of formulas in which at least one formula uses the result of another formula. The formula processor receives the formulas from a host and returns computed results for the formulas to the host for storage in a main memory. Formulas are received as a sequence of tokens, each token describing operands or operations.      The formula processor is pipelined; as one token is interpreted and processed by the formula processor, subsequent tokens are received. The formula processor uses a computation element which is capable of performing only certain operations; before attempting each operation described by a token, the computation element determines whether the operation can be performed by the computation element - if it can be performed, it is; otherwise, the host may perform the operation itself, or rewrite the operation so the formula processor can perform it. After the formula processor computes a result for a formula, it stores this result in a cache memory. Thereafter, the formula processor can retrieve the result stored in the cache memory and use the retrieved result to compute a subsequent formula. The operands to a formula may be values or pointers indicating how to locate values; the formula processor converts pointers into values when required for a computation by requesting resolution from the host microprocessor, or, alternatively, by retrieval from the cache.

Abstract: A method of nitriding an article of refractory-nitride-forming metal or metalloids is described. A consolidated metal or metalloid article is placed inside a microwave oven and nitrogen containing gas is introduced into the microwave oven. The metal or metalloid article is heated to a temperature sufficient to react the metal or metalloid with the nitrogen by applying a microwave energy within the microwave oven. The metal or metalloid article is maintained at that temperature for a period of time sufficient to convert the article of metall or metalloid to an article of refractory nitride. In addition, a method of applying a coating, such as coating of an oxide, a carbide, or a carbo-nitride, to an article of metal or metalloid by microwave heating is described.

Inventor: VON GERTTEN ERIC
IPC: B05B15/12
Filed: 1991-03-19
Abstract: 2078449 9114509 PCTABS00007 A device for spray painting, spray gluing and similar treatment of objects (2) comprises a spray gun (5) and a housing (6) containing the objects (2) to be sprayed. The spray gun (5) is positioned outside the housing (6), just in front of an opening (9) therein. The cross-sectional area of the opening (9) is considerably smaller than the internal cross-sectional area of the housing (6) that is perpendicular to the direction of spraying and located in a plane (13) through the object (2). Only a restricted air flow need be used in the spray device (1), since excess paint is effectively wet-separated and collected in a trap (16) in the housing (6), whence it is conveyed to a recovery vessel (17). This reduces the amount of paint particles that stick to the filter (11) of the spray device (1), for which reason the filter (11) need not be exchanged as often as in prior art spray booths.
