Granted: 1992-06-09
Abstract: Abstract:     The present invention is directed to a printed-wiring board produced by arranging a plurality of wiring circuit patterns on a printed-wiring board by screen printing and cutting out product regions corresponding to the wiring circuit patterns by punching them along the circumferences of the product regions.  The printed-wiring board according to the present invention is comprised of deviation detecting patterns for determining whether or not the condition of deviation of the printed pattern is within an allowable limit.  The deviation detecting patterns are printed at the time of the screen printing of the wiring circuit patterns in the vicinity of the position of the cut plane of the board for each product region of each wiring circuit pattern.  As a result, it is possible to determine whether or not the condition of the pattern deviation is within a specified allowable limit.

Abstract: ABSTRACT OF THE DISCLOSURE      A container for liquids is disclosed, wherein the container has an improved self draining means featuring a radially inclined ramp which slopes downward from the container pouring spout in the radially outward direction.  Beneath the drain ramp is an annular channel which receives liquids gravity draining from any azimuthal location on the ramp, and routes the liquids to a drain hole, returning the liquids to the container reservoir.  One or more projections may be disposed within the annular channel to partially block it.  This arrangement prevents any plastic shavings or other debris within the channel from migrating or being washed by the draining liquids to a location visible to the user or to the drain hole where such debris may contaminate the contents of the container.

Abstract: ARBITRATION TECHNIQUE FOR A SPLIT TRANSACTION   BUS IN A MULTIPROCESSOR COMPUTER SYSTEM                 Abstract of the Disclosure An arbitration technique for a split transaction bus of a computer system obtains higher data throughput as a result of giving responders (e.g. memories) absolute pri-ority over initiators (e.g. processors and I/O adapters), as a result of assigning all responders a higher priority than any initiator.  Precedence is also given to retrying initiators which failed to complete a transaction because the module to which the transfer was addressed was busy. the requests from non-retrying initiators are temporarily rescinded to give precedence to the requests from retrying initiators.  There is an absolute limit or bound to the number of requests which a retrying module may make before it is granted mastership of the bus to accomplish its transfer.  To accomplish test and set and memory scrub transactions with a minimum time loss, the bus of the computer system creates a null conductivity cycle immediately following the cycle in which the address of the memory location to be tested and set or scrubbed is transferred.

Abstract: For the force transmission between a wooden beam and another structural member, for example a further wooden beam, a blind bore and a ventilation bore, opening into the bottom thereof, are formed in the wooden beam. An insert is pushed into the blind bore. This insert consists of two spaced-apart closing plates, the outer cross-section of which corresponds to the cross-section of the blind bore, and of at least one, preferably four, force-transmission rods, the ends of which are welded to the mutually opposite sides of the closing plates. Bar dowels, which penetrate through spaces between adjacent force-transmission rods, are then driven in from the side of the wooden beam. Epoxy resin is then injected into the blind bore from outside until the entire blind bore and preferably also part of the ventilation bore are filled with the resin. When the resin has hardened, the resin body and the steel parts form a connector. Connecting members can be attached to the outer closing plate.

Abstract: The invention relates to a device for looping a radio-frequency test signal transmitted by the transmitter section in a transceiver to a receiver section for testing the transceiver. In the device of the invention, a transmitting-frequency test signal is first demodulated (23) to a base frequency and then to a receiving-frequency test signal. A control means (38) applies frequency setting signals to two frequency synthesizers (44, 45) before the beginning of each test interval and monitors the locking of the output frequencies of the synthesizers, thus preventing the output signal of the modulator (28) from being applied to the receiver section during the test interval if the output frequencies of the oscillator means (44, 45) have not locked to local oscillator frequencies determined by the frequency setting signals before the beginning of the test interval.

Abstract: ABSTRACT      The present invention is an improvement to a method of producing crude argon directly from the cold box of a cryogenic air separation unit.  The improvement is the production of crude argon containing greatly decreased concentrations of oxygen  i.e. <0.5% oxygen  without any loss in recovery.  The improvement is accomplished by using an effective number of theoretical stages in the side arm column so as to produce the desired argon product purity without sacrificing argon recovery; feeding crude liquid oxygen from the bottom of the high pressure column to the reboiler condenser located in the top of the argon side arm column at a rate in the range from about 1.04 to about 1.36 times the theoretical minimum flow of crude liquid oxygen necessary to completely vaporize that minimum flow of crude liquid oxygen to its dew point; and effectuating the intimate contact between the vapor and liquid phases in the argon side arm column by a combination of conventional sieve trays and low pressure drop, structured packings so that the pressure drop across this combination results in a pressure at the top of the argon side arm column such that the flow of crude liquid oxygen to the reboiler/condenser located in the top of the side arm column can be maintained in the appropriate range. Furthermore, the improvement is accomplished without an energy penalty in the cryogenic air separation unit.
