In a data processing system, an instruction is disclosed that generates a fault when a predetermined register position (e.g., the low or least significant bit position) has a predetermined logic signal (e.g., a logic '0' signal). This instruction provides a mechanism to determine when a Boolean value indicates a presence of a fault condition and provides a mechanism to generate the fault when pres...

A cylindrical high-pressure container comprises two halves (10, 12) which are telescopically pushed together and glued. The glue joint comprises an internal double cone (24, 26) which readily fits onto an external double cone (28, 30), wherewith the cones grip together in a manner to resist axial parting of the cones. A reinforcing filament or thread is wound around the joint to form a strengtheni...

R3078 A lubricant/working fluid composition for use in mechanical vapour compression type heat transfer devices is described wherein the working fluid is preferably tetrafluoroethane and the lubricant is an ester which is miscible with the working fluid at 10% over a temperature range of -50.degree.C to +80.degree.C and has a viscosity of 5 to 100 cSt at 40.degree.C. Useful esters include pentae...

In a multiprocessor data processing unit, a data element in the main memory unit, that has system wide significance, can have a requirement that this data element be altered in a controlled manner. Because other data processing units can have access to this data element, the alteration of the data element must be synchronized so the other data processing units are not in the process of altering th...

A guide fence providing an adjustable gap for accommodating variously configured cutting mechanisms which includes (i) a plurality of longitudinally elongated members having a generally V-shaped crosssection, and (ii) a means for releasable coupling a plurality of nested elongated members so as to create a planar guiding surface from a first lateral side of the nested members.

Two realizations of a method are disclosed for fabricating semiconductor substrate having an S0I beta -SiC on insulator structure. In the first realization, two substrates are prepared. The first substrate is silicon coated with SIO2 ; the second substrate is silicon on which beta -SiC is hetero-epitaxially grown. These substrates are bonded to each other by a heating process. During the heati...

A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the unit(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the...

56,016 A facsimile machine having a thin film electroluminescent pixel array which is used as the controlled light beam source for creating an image on a photoreceptive copying apparatus when the machine is in a write mode and using the same TFEL pixel array as a source of illuminating light to the scanning sensor when the machine is in the read mode. In other embodiments the primary light emiss...

Apparatus (38) and a method for forming a flat glass sheet is disclosed as utilizing a heating conveyor (42) that transfers a heated flat glass sheet to a downwardly facing surface (46) of a topside transfer device (44), a lower mold (48) having an upwardly facing full surface (50) at least a portion of which has an upwardly convex shape that receives the heated flat glass sheet from the topside t...
