Title: Sputter coating collimator with integral reactive gas distribution
Inventor: BARADA ANDREW
IPC: C23C14/04
Filed: 1994-05-11
Abstract: A sputter coating apparatus particularly useful for applying sputtered films, particularly reactively produced sputtered films such as titanium nitride, onto semiconductor wafers (16), is provided with a collimator (40) that includes a grid (42) of vanes (44a, 44b) for restricting the paths (32, 34) available for the sputtered material to take from the target (20) toward the wafer (16). A flow of fresh reactive gas is maintained on the surface (18) of the wafer (16) by gas outlets (54) carried by vanes (44a, 44b) of the collimator (40). The outlets (54) are supplied with the gas through passages (50) provided in the vanes (44a, 44b), so that the gas supply does not contribute to the shadowing of the sputtered material from the wafer (16) except in accordance with the intended shadowing for which the collimator (40) is provided.

Abstract: Interlocking concrete form modules (21) suitable for creating a concrete wall form is disclosed. The modules (21) have the general shape of a right rectangular parallelepiped with parallel side walls (23a, 23b) joined by integral webs (25a, 25b, 27a, 27b, 27c) that define a plurality of parallel elongate cavities (31). The edges of the side walls (23a, 23b) include tongues (33a, 33b) and grooves (35a, 35b) thatallow the modules (21) to be interlocked to form a wall. The ends of the webs are undercut such that cavities between the modules are created when the modules aresuitably interlocked. The between-the-module cavities lie orthogonal to the through-the-module cavities. The modules (21) are formed of an insulating material and left in place. Preferably, the tongues along one edge include notches aligned with the webs. In one embodiment, the modules (21) substantially entirely are formed of relatively dense (3-5 lb./ft.3) expanded polystyrene (EPS). The density of the EPS is adequate to hold threaded wall anchors. In an alternate embodiment, the modules (41) are formed of less dense (approximately 1.5 lb./ft.3) EPS and include embedded nonmetallic attachment elements (55, 57) that are sized and positioned such thatsurfaces of the attachment elements lie coplanar with the outer surfaces of the side walls (43a, 43b) of the modules (41). Preferably, the nonmetallic attachment elements (55, 57) span substantially the entire height of the modules to create equi-spaced furring strips that cover substantially the entire height of a wall formed when the modules are suitably assembled.

Filed: 1994-05-27
Abstract: An improved fiber reinforced glass composite includes a boron-containing refractory fiber having its surface enriched with boron nitride in a matrix of a black glass ceramic having the empirical formula SiCxOy where x ranges from about 0.5 to about 2.0, preferably 0.9 to 1.6 and y ranges from about 0.5 to 3.0, preferably 0.7 to 1.8. Preferably the black glass ceramic is derived from cyclosiloxane or non-cyclic siloxane monomers containing a vinyl group attached to silicon and/or a hydride-silicon group. The boron nitride-containing fiber is the product of treating the boron-containing fiber with ammonia at a temperature between about 1125 °C and 1250 °C. Fibrous failure rather than brittle fracture under stress can be obtained. In one embodiment, composites may be oxidized in air at temperature of up to 800 °C for 5 to 200 hours to improve the stress-strain properties.
Patent CA-2164622-A1 (CA)
Title: Grooved disk apparatus
Inventor: HAY ANDREW G
IPC: F04D17/16
Filed: 1994-06-08
Abstract: An apparatus (10) for transporting and metering particulate material including a transport duct having an inlet (14), an outlet (16), and at least one moving surface located therebetween having a downstream facing drive surface (56). The apparatus further includes a motive device for moving the moving surface between the inlet and the outlet towards the outlet (16).      The particulate material being compacted sufficiently to cause the formation of a bridge composed of substantially interlocking particulates spanning the width of the transport duct. The bridging of the particulates causes the particulates to become semi-hydrostatic in nature such that the force exerted by the downstream facing drive surface (56) upon particulates within the transport duct drives the entice mass of material through the transport duct towards the outlet (16). The apparatus is used to transport and meter particulate material under ambient conditions and against pressure.
Patent CA-2165126-A1 (CA)
Title: Dehydrogenation of a dehydrogenatable hydrocarbon using alkali metal liquid to remove hydrogen and supply heat of reaction
Inventor: OROSKAR ANIL R
IPC: C07C5/42
Filed: 1995-12-13
Abstract: Dehydrogenatable hydrocarbons are dehydrogenated by contacting the hydrocarbon with a liquid comprising an alkali metal in a dehydrogenation zone to produce a dehydrogenated hydrocarbon and an alkali metal halide. The resulting alkali metal hydride is removed from the zone and heated to produce a heated liquid alkali metal and hydrogen. The heated liquid alkali metal is recycled to the dehydrogenation zone to provide heat and elemental metal for hydrogen removal and the dehydrogenated hydrocarbon is recovered.
Patent CA-2166207-A1 (CA)
Title: Quadrupole with applied signal having off-resonance frequency
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1994-06-27
Abstract: A mass spectrometry method in which a combined field (comprising a trapping field and supplemental field) is established and at least one parameter of the combined field is changed to excite ions trapped in the combined field sequentially (such as for detection). The supplemental field is a periodically varying field having an off-resonance frequency, in the sense that the supplemental field frequency nearly matches (but differs from) a frequency of motion of an ion stably trapped by the trapping field alone. Sequential ion excitation in accordance with the invention can rapidly excite each ion to a degree sufficient for a desired purpose but insufficient for ejection from the trap. The amplitude of the supplemental field is kept sufficiently high to excite ions (via an off-resonance excitation mechanism) before they undergo resonant excitation.
Patent CA-2167784-A1 (CA)
Title: Multi-volume audit trails for fault tolerant computers
Inventor: SKARPELOS MICHAEL J
IPC: G06F11/14
Filed: 1996-01-22
Abstract: A fault tolerant computer system distributes audit trail files containing audit records, across an arbitrary number of disk volumes.  After one audit trail file becomes full, audit records are directed toward a next audit trail file stored on a different disk volume.  Storage of newly generated audit rotates through the disk volumes in round-robin fashion.  Full audit trail files are eventually archived and their space becomes available again for renaming and storage of newly generated audit records. The number of audit records available for on-line recovery after a failure is not limited to the storage capacity of any single disk volume. Furthermore, there is no contention for disk access between archiving of full audit trail files and storage of newly generated audit records.
