Abstract: ABSTRACT OF THE DISCLOSURE   A lamp annealing technique for a semiconductor wafer is disclosed.  In a heating step of an annealing process, cooling gas is flown toward a periphery of the semiconductor wafer, and in a steady state step and a cooling step, cooling gas is blown toward a center of the semiconductor wafer.  In this manner, a temperature difference between the center and the periphery of the semiconductor wafer is eliminated throughout the annealing process.

Title: Pilot valve for control valves and method of operation
Inventor: MCNEELY MICHAEL D
IPC: F16K31/126
Filed: 1991-05-16
Abstract: ABSTRACT A pilot valve (40) for a control valve (14) has a separate auxiliary source of high pressure fluid (106) for the operation of the pilot valve (40). The dome chamber (36) of the control valve (14), the inlet fluid chamber (72), and the intermediate fluid chamber (104) are exposed only to the auxiliary source of fluid (106). Thus, process fluid from the sensing line (62) does not contaminate the spool valve (76) or the dome chamber (36).

Inventor: MOREY NORVAL K
IPC: F23G7/10
Filed: 1991-12-19
Abstract: A bottom-feed, biomass material gasification system feeds fuel such as green and wet woodchips from below up through a central opening in a stationary, perforate fire table which supports the mound-like fuel bed which is formed.  A plurality of ring-like air manifolds contiguously below the fire table, and surrounding the fuel supply tube are separately provided with air in a controlled manner according to the demand for the combustible gas produced, and a greater volume of air is supplied to the centralmost manifold, than to the outer manifold, or manifolds.  The system includes, in addition to a primary heating chamber, a secondary heating chamber which receives the hot gases generated in the primary chamber and, via a centrifugal cyclonic action, combusts fly ash particles which may remain entrained in the gas, before passing the hot gases to the boiler burner for combustion.  The atmosphere in the primary combustion chamber is partially starved, insofar as the supply of oxygen is concerned, and is maintained under a lower pressure than the gases which outlet from the primary chamber to the secondary chamber so that there is a continuous suction or draft pulling the hot gases generated in the primary chamber directly to the secondary chamber.  An ash disposal system has paddles mounted on a rotary band bearing on the fire table for moving the ash which is generated from the perimeter of the fire table, when the ash build-up is sufficient to warrant it.

Title: Manufacture of peroxidic compositions
Inventor: MCDONOGH COLIN F
IPC: C01B15/06
Filed: 1992-01-09
Abstract: ABSTRACT          Manufacture of Peroxidic Compositions Production of peroxomonosulphuric acid (Caro's acid) by reaction between concentrated hydrogen peroxide and sulphuric acid solutions can be impaired substantially when substoichiometric amounts of sulphuric acid are employed.  The problem is ameliorated or removed by first forming a body of sulphuric acid-rich fluid (usually the smaller volume) and thereafter introducing into that body of fluid the hydrogen peroxide solution (usually the larger volume).   The reaction mixture progressively becomes sulphuric acid-lean,   The body of fluid is advantageously either concentrated sulphuric acid itself, or a premix formed by reaction between hydrogen peroxide and at least an equimolar amount of sulphuric acid.   The process is particularly suitable for making Caro's acid when from 0,02 to 0.5 moles of sulphuric acid is employed per mole of hydrogen peroxide.

Title: Method and apparatus for retorting packages having sealed flexible lids
Inventor: KALAWNI SHANTU L
IPC: B65B57/00
Filed: 1992-01-30
Abstract: METHOD AND APPARATUS FOR RETORTING PACKAGES HAVING SEALED FLEXIBLE LIDS                       ABSTRACT An apparatus and method are described for generating a retort cycle pressure control in a reliable manner.  A proximity sensor is used to detect motions of a flexible lid of a hermetically sealed package that contains food which releases vapor and gases when the package is retorted.  The sensor is not in physical contact with the package an does not influence the lid motion it is intended to monitor.  A signal from the sensor is used to produce a counter-pressure in the retort sufficient to keep the lid motion to a minimum throughout the retort cycle.  A plurality of packages can be so used during a retort cycle to generate averaged values for a counter-pressure control.           LPATCASE:145

Title: Process to defend objects emitting an infrared radiation and droppable bodies to carry out the process
Inventor: BANNASCH HEINZ
IPC: F41H9/06
Filed: 1992-03-31
Abstract: A process is provided to defend objects emitting an infrared radiation, in particular ships, against missiles, which are equipped with intelligent infrared seeker heads.  Following location of the missile, adjacent to the object a large area pyrotechnical perturbing radiation cloud, which releases in a short period of time high infrared radiation, which hashes the locking on and pursuit electronics of the seeker head, and subsequently releases for a comparatively long period a weak infrared radiation, is produced between the object and the missile. Immediately following the end of the high radiation phase of the perturbing radiation cloud, several fake target clouds are set up that lead the missile then step-by-step away from the object to be defended. The perturbing radiation clouds are produced by the droppable bodies, whose active masses comprise phosphorus flares and phosphorus pellets.
