Title: Induction motor synthesis control apparatus and method
Inventor: SHERO DAVID J
IPC: B60L11/18
Filed: 1986-01-30
Granted: 1991-05-21
Abstract: ABSTRACT OF THE DISCLOSURE          An  arrangement  of  interconnected  timers  is provided for operation with a microprocessor programmed to determine  time  delay counts  that  are  fed out to  these timers such that the timers can take care of the actual task of firing GTO inverter switches or not  firing GTO inverter switches coupled with an AC traction motor for a vehicle.   It  is  necessary  to  have  correct  transitions between the minus GTO switch and the plus GTO switch being ON for providing the desired motor voltage conditions with minimum electromagnetic  interference  in relation to  the power  supply.   In  addition  the use  of timer  queues  in complicated synthesis  modes  like  the PWM  and the quasi six-step  operates  to  give  the  microprocessor  adequate operating time for reasonable control signal time duration calculations.  The timers are synchronized in hardware by a single  crystal  frequency,  and they are  synchronized  in software such that the three phase independent waveforms stay 120° apart.

Abstract: ABSTRACT     Chromogenic materials which react to give a color reaction when in the presence of a peroxide ROOR' decomposing to give a radical oxygen are unstable when dissolved to give working solutions for use in chromogenic reactions.  Compositions containing in addition to the chromogenic material also a peroxide needed in the said reaction are also unstable, leading to premature appearance of color.  Stable chemical compositions containing chromogenic materials and stable compositions  containing mixtures  of  chromogenic materials  and peroxides are described, which can be used in chromogenic reactions after having been stored for long periods of time.  Also described are stabilizing chemical compositions and methods for obtaining the said stable compositions.

Granted: 1991-06-18
Abstract: Abstract "ANCHOR"       A marine anchor for mooring an object eg., ship, oil rig etc. to the sea bed comprises a fluke (2) with a shank (3) attached to the fluke.  To enable the anchor to orientate on the sea bed from an inverted position to an upright working position, trigger elements in the form of auxiliary flukes (23, 24) are supported by respective lugs (21, 22) upstanding from the fluke on either side of the anchors vertical plane of symmetry (S-S).  The auxiliarly flukes (23, 24) extend laterally from the lugs (21, 22) and are inclined at an acute angle (B1) to the main fluke (2).  The anchor includes support means (4) arranged such that when the anchor lies inverted on a firm sea bed one of the auxiliary flukes (23, 24) is located in position for digging in when the anchor is pulled forwardly.  Anchor orientation is achieved by the anchor tilting about the dug in auxiliary fluke (23, 24).

Title: Apparatus and method for providing a cache memory unit with a write operation utilizing two system clock cycles
Inventor: STEWART ROBERT E
IPC: G06F12/08
Filed: 1987-01-28
Granted: 1990-11-27
Abstract: ABSTRACT    A cache memory unit is disclosed in which, in response to the application of a write command, the write operation is performed in two system clock cycles.  During the first clock cycle the data signal group is stored in a temporary storage unit while a determination is made if the address associated with the data signal group is present in the cache memory unit. When the address is present, the data signal group is stored in the cache memory unit during the next application of a write command to the cache memory unit. If a read command is applied to the cache memory unit involving the data signal group stored in the temporary storage unit, then this data signal group is transferred to the central processing unit in response to the read command.  Instead of performing the storage into the cache memory unit as a result of the next write command, the storage can occur during any free cycle.

Title: Apparatus and method for providing a settling time cycle for a system bus in a data processing system
Inventor: STEWART ROBERT E
IPC: G06F15/177
Filed: 1987-01-28
Granted: 1990-12-18
Abstract: ABSTRACT      In a data processing system in which a plurality of data processing units or subsystems exchange logic signal groups by means of a system bus, apparatus is provided to allow sufficient time to permit transients on the system bus to decay, thereby increasing the integrity of the data.  When the logic signal groups are applied to the system bus via conducting and nonconducting transistors,  the presence of a logic signal on the system bus immediately prior to the application of a set of logic signals from a different data processing unit can delay the on-set of conduction of the most recently activated transistors,  thereby resulting in transients of long duration.  To accommodate these long transient conditions,  the application of the new set of logic signals can be delayed until the transients on the system bus have been attenuated.  Apparatus is disclosed for prohibiting access to the system bus by any subsystem during the system clock cycle following a subsystem access or by preventing access to the system bus by subsystems determined by the subsystem having access during the prior system clock cycle.

Abstract: ABSTRACT         Novel epoxy-urethane resins are produced by the reaction of a urethane-alkanolamine adduct with an epoxy resin.  The urethane-alkanolamine adduct is prepared by reacting a urethane prepolymer with a sterically hindered N-substituted ethanolamine such as t-butyl ethanolamine.  The epoxy-urethane resin can be cured using ordinary epoxy curing agents for application as waterproofing membranes, joint sealants, and adhesives.  Two-part resin systems comprising epoxy-urethane resins of the invention as the first part, and an appropriate curing agent as the second part avoid disadvantages characteristic of resin mixtures that rely on urethane cure chemistry.

Title: Producing volatile metals
Inventor: HARRIS RALPH
IPC: C22B5/04
Filed: 1987-06-08
Granted: 1992-08-25
Abstract: ABSTRACT:      Value metal belonging to Group IA or IIA of the Periodic Table is recovered from its ore or concentrate by mixing the latter, in finely divided form, with an excess of molten lix-ivlant reaction metal.  This forms a mixture of an alloy of the value metal and the reaction metal and a dispersate of partly depleted source material.  Value metal is vacuum refined from the alloy and recovered.  The method may be conveniently carried out, continuouly, in a closed vessel by the use of an apparatus according to the invention, having an upwardly extending treating passage for containing the reaction metal and extending upwardly to a vacuum space.  Lifting gas is injected into the mixture to provide emission of the mixture in the form of a volley of drop-lets from which the value metal is vacuumed off.  The remaining reaction metal and partly depleted source material are deposited in a catchment  bath. The material from the catchment bath is partly recycled through a recycling passage to the reaction passage and partly passed to a reservoir for the reaction metal from which depleted source material is removed.Barometric legs lead from a submerged position in the reservoir to the bottom of the reaction passage and the bottom of the catchment bath respec-tively and electromagnetic pumps control the flow through these legs.

Abstract: Abstract In a single phase AC induction motor having a main winding     and an auxiliary winding     both connectable to an AC power source    , and having a start switch         for automatically connecting and disconnecting the auxiliary winding     to and from the AC source     in starting and running modes, respectively, and having a user operated reversing switch           for reversing the voltage polarity applied from the AC source    to one of the windings relative to the other winding, low cost circuitry is provided for detecting the polarity reversal by sensing when one of the main and auxiliary winding voltages shifts from a leading to a lagging position relative to the other winding voltage, whereupon the circuit auto-matically instantly reconnects the auxiliary winding to the AC source     to immediately apply reverse torque.  A first voltage comparator       senses a given polarity and magnitude of main winding voltage, and a second voltage comparator       senses a given polarity and magnitude of auxiliary winding voltage. The output of the second comparator       is differen-tiated      , and a third voltage comparator compares output pulses       from the first comparator and differentiated output pulses       from the second comparator       and instantaneously senses polarity reversal when one of the pulses shifts relative to the other, and in turn actuates the start switch
