Title: Encoding and decoding system
Inventor: JOHNSEN EDWARD L
IPC: G06K15/00
Filed: 1988-08-11
Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE     A system for processing coupons, documents, or the like including the assembling multiple encoding and decoding of coupons, or other documents requiring coding for the purpose of making the coupon uniquely identifiable and traceable.  A machine encodes individual coupons or booklets or other documents with a unique code, a subsequent machine reads the encoded coupon or booklet of coupons and applies additional information such as a person's name and address, and another unique code to the coupon, coupon booklet or the like, and records all of this data in a computer master data base.  The coupons, coupon booklets, or the like, are then issued to the person whose name appears on the document.  After presentation of the coupon it is then decoded and compared to the master data base to validate it or cancel it, and can be stored for demographic or geographic analysis in the master data base.  The system may be combined with a retail store's automated system which reads the product information and calculates price after each coupon has been decoded.  The computer compares the coupon to all purchases being made, and if there is a match of a presented coupon and an item purchased, the decoding machine validates the coupon and the store system then deducts the coupon credit from the presenter's invoice.

Title: Apparatus and method for braking an electric motor
Inventor: UNSWORTH PETER J
IPC: H02P3/20
Filed: 1988-08-26
Granted: 1992-01-21
Abstract: ABSTRACT   An electric motor is coupled to the power lines by thyristors.  The motor is braked by triggering the thyris-tors at the proper times to produce a electro-magnetic field within the motor which opposes the residual magnetic field of the rotor.  The proper time to trigger the thyristors is determined by comparing the polarity of the voltage across the power lines to the back emf voltage from the motor.  The thyristors are triggered when these two voltages have oppo-site polarities.  The braking circuit also regulates the duty cycle of the thyristors to control the magnitude of the current applied to brake the motor.

Abstract: IMPROVED SCHEME FOR INSURING DATA CONSISTENCY BETWEEN A      PLURALITY OF CACHE MEMORIES AND THE MAIN MEMORY     IN A MULTI-PROCESSOR COMPUTER SYSTEM              ABSTRACT A method for insuring data consistency between a plurality of individual processor cache memories and the main memory in a multi-processor cache memories and the main memory in a multi-processor computer system is provided which is capable of (1) detecting when one of a set of predefined data inconsistency states occurs as a data transaction request is being processed, and (2) correcting the data inconsistency states so that the operation may be executed in a correct and consistent manner.  I particular, the method is adapted to address two kinds of data inconsistency states:  (1) A request for a operation from a system unit to main memory when the location to be written to is present in the cache of some processor unit-in such a case, data in the cache is "state" and the data inconsistency is avoided by preventing the associated processor from using the "stale" data; and (2)  when a read operation is requested of main memory by a system unit and the location to be read may be written or has already been written in the cache of some processor - in this case, the data in main memory is "stale" and the data inconsistency is avoided by insuring that the data returned to the requesting unit is the updated data in the cache.  The presence of one of the above-described data inconsistency states is detected in a SCU-based multi-processing system by providing the SCU with means for maintaining a copy of the cache directories for each of the processor caches.  The SCU continually compares address data accompanying memory access requests with what is stored in the SCU cache directories in order to determine the presence of predefined conditions indicative of data inconsistencies, and subsequently executes corresponding predefined fix-up sequences.

Abstract: ABSTRACT A low reflectance glass  surface is disclosed which  includes  a  particular  combination  of  surface structures which  produce  a  low  reflectance  yet  high clarity glass.  The surface structure includes a plurality of  randomly distributed  surface  scallops which have a diameter of about 100 to 2000 micrometers, with a plural-ity  of  islands  at  spaced-apart  intervals  distributed thereover, at a density of about 25 to 500 islands per square millimeter.   The  glass  surface preferably also includes  a  microporous  structure  which  is uniformly provided across the surface of both the scallops and the islands,  with  the  micropores  being  about  0.2  to  1.0 micrometers in diameter.   The glass further includes a skeletalized silica structure of 200 to 600 angstroms in diameter,  uniformly distributed over the  surface.   By combining the various surface structures on one piece of glass,  unique  properties  of  low  reflectance yet  high clarity are provided, which is particularly suitable for use in picture frames where any distortion would distract from viewing  a picture  contained therein  and also  in computer or t.v. screens where distortion or glare could produce operator fatigue or stress.  The glass structure is achieved by a process which is readily adaptable to existing production lines without requiring major modi-fications.  Consequently, the low glare high clarity glass can be produced economically, allowing use in applications not previously adaptable to the highly expensive anti-reflection glass previously available.

Title: Segmented arch structure
Inventor: QUAILE ALLAN T
IPC: E04B1/32
Filed: 1989-09-19
Granted: 1994-06-07
Abstract: ABSTRACT          A segmented arch structure is prefabricated from compression units, the units generally comprising one or more standard arch segment elements, and end anchor elements.  Each arch segment comprises a trapezoidal frame structure fabricated from short lengths of sawn lumber, and fastened at the corner junctions of the respective individual members to form the respective arch segment element, each element comprising a segment of the arch.  The arch is assembled in combination with one or more elongated pre-stressing elements and the pre-stressing elements tensioned to a sufficient extent, relative to the geometry and applied load to be born by the arch, that, in combination with other inter-element fastening means the arch elements are maintained substantially under compression across the abutting segment end faces.  The arch is generally pin jointed at its ends, and frequently at the centre thereof, to preclude the development of local bending moments at the base and apex of the arch.          In the preferred element construction a set of centre-to-centre triangulation braces form an inner, diamond-brace construction, having a lateral brace thereacross.  An alternative X-brace construction, usually combining therewith a lateral pair of struts to the centre points of the parallel frame members of the trapezoidal frame, can be used.  This can facilitate relocation of the pre-stressing element from off the geometric centre line of the frame, if desired.  Such shifting of the axis of compression may also be readily effected with K-form and with single side or double sided sheath bracing.

Abstract: ABSTRACT OF THE INVENTION A rotary atomizer (20) includes a manifold assembly (22) adapted to be attached to a mechanism for moving the atomizer and an air bearing turbine motor housing assembly (21) releasably secured to the manifold assembly.  Sources of pressured fluid for actuating the atomizer and coating fluid are connected to the manifold (29) which has fittings (32, 33, 34, 35, 36) for releasably sealing to apertures (42) in the rear cover (43) of the housing assembly.  The opposite end of the housing includes a shaping air cap (24) and a shaping air ring (25) which cooperate to define an annulus for discharging a thin ring of shaping air over the peripheral edge of an atomizer bell (26) to direct fluid particles toward a target.  Exhaust air from the turbine motor (46) is vented to the inside of the housing and directed to a chamber (79) behind the atomizer bell to aid in directing the fluid particles.  A magnetic speed pickup (103, 104) generates a signal which is coupled through a circuit (105, 106) that electrically isolates the high voltage which is applied to the atomizer to electrostatically charge the coating particles.
