Patent CA-2062925-A1 (CA)
Title: Reduced weight nozzle actuation mechanism
Inventor: NASH DUDLEY O
IPC: F02K1/15
Filed: 1992-03-12
Abstract: A fluid supply and synchronizing mechanism are provided for a jet engine exhaust nozzle. The exhaust nozzle has flaps which are moved by flap mounted actuators which move with the flaps.  The fluid supply includes a supply tube, a return tube and a strut for each actuator. The two tubes and strut are connected to each actuator for movement with the actuator.  The strut prevents flexing of the tubes during movement  The synchronizing mechanism interconnects the flaps so that movement of any one flap is transmitted to all other flaps thereby retaining nozzle symmetry.

Title: Enzyme amplified lanthanide chelate luminescence assay
Inventor: EVANGELISTA RAMON A
IPC: G01N33/542
Filed: 1990-11-13
Abstract: A method and compounds useful for this method are described for enzyme-amplified signal detection in analytical assays requiring extremely high detection sensitivity which uses a substrate capable of being transformed by an enzyme from a com-pound which does not form a luminescent lanthanide chelate into a product which forms a luminescent lanthanide chelate. The method in which a substrate not capable of forming a highly luminescent lanthanide chelate is enzymatically altered to produce a product which forms a highly luminescent lanthanide chelate and hence is particularly useful in time-resolved luminescence anal-ysis as required in many different heterogeneous or homogeneous assay formats is described herein. Above mentioned com-pounds include benzoic acid, 2-phosphonooxy-derivatives (a), benzophenone, 4-phosphonooxy-derivates (.beta.), as well as (~) and (.delta.).

Patent CA-2077017-A1 (CA)
Title: Synchronous digital signal to asynchronous digital signal desynchronizer
Inventor: MEDIAVILLA RICARDO
IPC: H04J3/07
Filed: 1992-08-27
Abstract: Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous digital signal, e.g., a DS3 signal, from a received synchronous digital signal, e.g., a SONET STS-1 signal. The improved jitter performance results from the use of a unique dynamic bit leaking arrangement in conjunction with a digital phase locked loop and desynchronizing elastic store. An optimum bit leak interval is obtained by controllably leaking a greater number of shorter interval STS-1 bits than the number of received pointer adjustment bits.Additionally, the affect of random pointer adjustments and the superposition of randomly received pointer adjustments on a periodic sequence of received pointeradjustments is minimized by employing a "static" queue of pointer adjustment bits to be leaked. The queue is dynamically maintained at its "static" count so that there are always bits in the queue to be leaked at the desired optimum bit leak interval even in the presence of randomly received pointer adjustments.

Title: Inclined pressure boost pump
Inventor: INKLEBARGER BOBBY A
IPC: F04D13/08
Filed: 1992-09-03
Abstract: ABSTRACT OF THE DISCLOSURE      A submersible pump assembly is mounted within a pressure vessel or jacket for use at the surface for an injection well.  The jacket has an inlet which connects to a feed pump for supplying feed water under pressure. The motor, seal section and pump mount within the jacket, with a discharge conduit extending out a discharge end of the jacket.  The support for the jacket inclines the jacket at an inclination relative to horizontal.  This causes any gases in the feed water to migrate toward and accumulate at the upper end of the jacket. A bleed off valve is employed to bleed off the accumulation of gases.

Title: Wound-wire casing process and machine
Inventor: SPERLING ECKHARD U
IPC: B21F3/02
Filed: 1993-03-22
Abstract: WOUND-WIRE CASING PROCESS AND MACHINE                    ABSTRACT      A process for manufacturing continuous casing in substantially unlimited lengths involves the mounting and centering of a coil of casing wire stock, for the rotation thereof about the main axis of the casing product.  The rotating wire stock is drawn off from the coil, over a series of self-aligning guide pulleys, in an outward, constantly varying halical path, and directed inwardly to an adjustable coil-forming mechanism which deforms the stock into a continuous succession of non-rotating, axially advancing close turns of uniform diameter, to form an endless guide casing or conduit.  The casing or conduit may be formed about a tubular liner, such as a plastic tube.  If formed with its turns in abutting relation the casing is effectively axially incompressible, for uses such as emergency brake cable casing.      Control of the coil forming mechanism to impart a predetermined prestress to the wire stock as it is curved into its turns can increase the residual compressive force exerted between adjacent coils, thereby stiffening the casing, to resist longitudinal bending deflection thereof under the influence of self-weight or lateral bending moment loads.  By providing continuous lengths of 1000 feet (300 meters, approx) and greater, subsequent operations thereon can also be made substantially continuous, with marked cost savings and economics.  The casing producing machine is small and compact, with a self-contained stock magazine to receive and center a coil of casing wire, and provides as product output an axially advancing, substantially non-rotating casing.
