Title: Compressor unloader
Inventor: WOOD MARK W
IPC: F04B49/24
Filed: 1993-05-07
Abstract: COMPRESSOR UNLOADER        Abstract An unloader (11) to facilitate starting and idling an air compressor motor (12). In one embodiment, the compressor (10) has a valve (29), such as an inlet or suction valve, having one or more reeds (28) which are biased to a normally closed position. An end of a wire or spring or a similar mechanism (37) is mounted to hold the valve open to unload the compressor when the motor is stopped or operated below a predetermined minimum speed. The compressor motor (12) also drives a fan (35) which cools the compressor. When the motor (12) reaches the predetermined minimum speed, cooling air flow from the fan moves a vane (42) which is connected to move the wire, spring or other mechanism (37) clear of the valve (29), allowing the valve to close to load the compressor (10). In a modified embodiment of a starting unloader, an opening (110) is provided to vent the high pressure output from the compressor (90) when the motor (91) is stopped or idling. When the compressor motor reaches a predetermined speed, a flow of cooling air from a fan (93) driven by the motor moves a vane (111) to close the vent passage (110).

Title: Apparatus and methods for applying conformal coatings to electronic circuit boards
Inventor: BOGER BENTLEY
IPC: B05C5/02
Filed: 1993-06-18
Abstract: Abstract of the Disclosure:            Apparatus   and   methods   for   producing intermittent,  discrete patterns of coating material onto  discrete  irregular  substrate  areas,  such  as electronic circuit boards,  where the patterns have sharp, square leading and trailing edges, as well as side edges.  A slot nozzle die has elongated air slots along the slot extrusion opening.  In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the coating material flow. Also, the air flow is continued beyond that point in time, when the coating material flow ceases.  The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds.          Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the circuit board.  The air flow carries the film coating material  to  the  circuit  board  for  deposition  in discrete areas thereon.  The sharp cut-on and cut-off accommodate multiple discrete area coating or multiple automated circuit board coating.

Title: Electrodeless fluorescent lamp shield for reduction of electromagnetic interference and dielectric losses
Inventor: EL-HAMAMSY SAYED-AMR A
IPC: H01J65/04
Filed: 1993-08-12
Abstract: ELECTRODELESS FLUORESCENT LAMP    SHIELD FOR REDUCTION OF ELECTROMAGNETIC INTERFERENCE AND        DIELECTRIC LOSSES   Abstract An electrodeless fluorescent lamp of the type having a solenoidal drive coil wound about a ferrite core includes an inner shield between the coil and the core and further includes an outer shield about the coil.  The shields are preferably constructed of sheets of flexible polyimide material with vertical bands of metal etched thereon.  The metal bands are connected to ground in order to shield the core and the plasma from the electric field generated about the drive coil.  By thus shielding the core, the capacitance between the coil and the core is effectively short-circuited, substantially reducing or eliminating dielectric losses of the core.  The outer shield substantially reduces the EMI generated by the drive coil.
Patent CA-2105020-A1 (CA)
Inventor: HOFFMAN HARRELL
IPC: G06F9/48
Filed: 1993-08-27
Abstract: A system and method for managing service requests from peripherals connected to a personal computer or workstation by operating both in an interrupt mode and a polling mode, with selective transition therebetween. In one practice of the invention, peripheral device service requests are first managed on an interrupt basis, then transition to a polling mode when the interrupt rate exceeds a rate threshold, and subsequently revert back to the interrupt mode when the rate again decreases below a threshold. The transition is dynamic and situation adjustable by parameter selection both as to the number of service requests and as to the time interval used to initiate transition between the interrupt and polling modes.

Title: Process for casting metals and device for implementing such a process
Inventor: SROSTLIK PETER
IPC: B22D17/12
Filed: 1992-03-12
Abstract: Abstract Process for casting metals and a device to effect such a process The invention relates to a process for casting metals, in particular alloys of low melting point, during which process the liquid metal is filled from the bottom to the top into a casting mould (3) by way of a casting runner (4) and a filling hole (5), arranged at the lowest point of a casting mould (3), and a device to effect this process.  The direct further use of the casting (7), by avoiding a sprue to be subsequently processed, is possible due to the fact that after totally filling the casting mould (3) and only partial solidification of the metal in the casting mould (3), the casting pressure is decreased or turned off, so that the liquid metal flows back out of the casting mould only over a return flow channel (13), whose cross section is significantly smaller than the cross section of the casting runner (4), and that a ram, whose face (20) corresponds in size and shape to the outer contour of the casting (7) in the region of the filling hole (5), is pushed at least over the last segment (16) of the casting runner (4), displacing the liquid metal, present in the last segment, into the casting mould (3) as far in the direction of the mould interior until the face (20) of the ram (18) aligns with the inner contour of the casting mould (3).

IPC: G01V1/28
Filed: 1992-07-27
Abstract: In the exploration for petroleum or natural gas, drilling targets arc identified by locating local maxima of horizontal gradient in the top-of-geopressure surface of a region of exploration. The probability of finding hydrocarbon deposits is significantly improved where the drilling targets are local maxima of the horizontal gradient in the top-of-geopressure surface which coincide with local maxima of subsurface heat flow in the region of exploration, particularly where the local maxima in the horizontal gradient of the top-of-geopressure surface is concentrated across major fault offsets and are parallel to the predominant strike directions of the faults. The top-of-geopressure surface may be remotely sensed by performing complex trace analysis on reflection seismic traces gathered for the region of exploration to drive corresponding reflection strength attribute traces. The corresponding reflection strength traces are first smoothed and then subject to further complex trace analysis to derive the envelope amplitudes of the smoothed reflection strength traces, which are referred to as second reflection strength traces. The second reflection strength traces are then analyzed to locate an uppermost distinct subsurface boundary between high and low amplitude components thereof. Such a distinct boundary is then identified as the top-of-geopressure surface for the region of exploration.

Title: Method for determining and controlling the concentration of active substances included for cleaning and disinfection in aqueous cleaning and disinfecting solutions
Inventor: LAUFENBERG ALFRED
IPC: G05D11/13
Filed: 1992-08-13
Abstract: (57) Abstract The invention concerns a method of determining the concentration of an iodine/iodide-containing active substance in aqueous solutions intended for use in the cleaning or disinfection of containers such as bottles, drums, kegs, cases and tanks and/ or pipe lines in the food-processing industry, as well as for industrial-scale cleaning in continuous washing plants, the concentra-tion of the active substances in the solution being measured by determining the iodine/iodide content of the solution. The inven-tion provides a rapid, reliable and accurate method which is not prone to interference and can be used on a continuous basis. In addition, it makes it possible to automate the process by which the active substance is kept at the required concentration. In parti-cular, the method proposed can be employed in an integrated cleaning-in-place system. These advantages are achieved by the in-vention by virtue of the fact that the iodide-ion concentration in the solution is measured potentiometrically using electrodes which behave selectively towards iodide ions, and the concentration of the active substance calculated from the measurement re-sults obtained, the iodine/iodide concentration in the solution lying between 0.1 and 1000 ppm, in particular between 1 and 20 ppm.

Title: Method and apparatus for generating nuclear fusion energy by coherent bosons
Inventor: LO SHUI-YIN
IPC: G21B1/00
Filed: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE      With an extremely short laser pulse with not too high an intensity it is possible to ionize deuterium, or helium into coherent bosons such as coherent deuterons and coherent alpha particles.  To achieve this coherence it is important that certain critical conditions are satisfied so that plasma instabilities such as stimulated Raman scattering, stimulated Brillouin scattering, parametric instability have not enough time to grow to destroy the coherence.  The electrons created during the multiphoton ionization process also must not recombine with the ions or to destroy the coherence of the ions by electromagnetic scattering.  With the creation of coherent deuterons and coherent alpha particles together, the fusion rate of coherent deuterons into coherent alpha particles will be greatly enhanced.  The nuclear fusion energy thus released can be utilized.
