Patent CA-2115960-A1 (CA)
Title: Testing circuit
Inventor: MARSH MICHAEL J C
IPC: F42C21/00
Filed: 1994-02-18
Abstract: ABSTRACT   A testing circuit is provided for testing the operability both of a load and of a capacitor incorporated into a main detonator circuit and arranged to discharge into the load for detonation thereof. A test pulse is generated at a central controller to which a ring of detonators is connected on a harness. The test pulse is routed via the harness for storage in the capacitor. A controlled switch is operated to allow the capacitor to discharge into the load. A transistor is operated by the discharge signal, the transistor having an output for delivering a discharge value signal in response to the discharge signal falling below a threshold value. The discharge value signal is latched and is in turn used to inhibit a local oscillator. The inhibited signal from the oscillator is routed back to the controller so as to indicate a fault either in the capacitor or in the load.

Title: Method of producing coated particles using a disintegrator apparatus
Inventor: GORYNIN IGOR V
IPC: B22F1/17
Filed: 1992-08-31
Abstract: A metal-coated particle is prepared by providing a disintegrator apparatus with a working chamber containing counter-rotating disks equipped with teeth design to accelerate particles towards one another, providing a first material and a second metal as powders, such that the first material is harder than the second metal and introducing the first material and second metal powders into the working chamber of the disintegrator apparatus, whereby the soft second metal collides with the hard material and is coated onto the surface of the hard first material. A metal-coated metal with an intermetallic interface is prepared by introducing a first material and a second metal as powders into a disintegrator working chamber containing counter-rotating disks and teeth designed to accelerate particles towards one another. The first material is harder than the second metal and is capable of reacting with the second metal to form an intermetallic compound. The disks of the disintegrator are counter-rotated so as to cause the metal powders to collide with each other, whereby the hard metal powder is mechanically coated by second metal. The rate of rotation of the counter-rotating disks are further increased in a high velocity process whereby high local temperatures generated on impact cause a reaction to occur at the first material/second metal interface to form an intermetallic compound.

Title: Integral air compressor system
Inventor: JOHNSON JOHN L JR
IPC: F04B41/04
Filed: 1994-03-21
Abstract: Abstract of the Disclosure INTEGRAL AIR COMPRESSION SYSTEM           Air compression systems for internal combustion engines are utilizing an integral part of the engine to produce the compressed air necessary for operating the brakes of a vehicle.  The ability to produce compressed air from an integral part of the engine is important in order to reduce the cost and weight associated with the engine and to increase performance capability and reliability.  The integral air compression system includes a valve means associated with one of a plurality of combustion chambers.  A housing is connected to a cylinder head and has  first and second bore.  A master piston is disposed within the first bore to define a first oil chamber.  A slave piston is disposed within the second bore to define a second oil chamber.  A means fluidly connects the first and second oil chambers.  The master piston is forced toward the first oil chamber when another one of the combustion chambers is in the exhaust stroke.  The second oil chamber becomes pressurized and forces the slave piston to open the valve means during the compression stroke of the one combustion chamber allowing compressed air to flow through a passage in the head and into a storing means.  A means for monitoring the pressure in the storing means is utilized to control the integral air compression system.

Title: Jak kinases and regulation of cytokine signal transduction
Inventor: IHLE JAMES N
IPC: C12Q1/68
Filed: 1994-06-22
Abstract: Jak Kinases and Regulation of Cytokine Signal Transduction Abstract The present invention is based on the discovery that a critical step in the cellular response to several cytokines is the activation (i.e. tyrosine phosphorylation) of a member of the Jak kinase family. In particular, several cytokines whose activity is mediated by the activation of Jak2 kinase are identified. The present invention provides novel methods for regulating the cellular response to these cytokines by inhibiting or enhancing the Jak kinase activity which mediates the response. Assays for identifying inhibitors of Jak kinase activity or cytokine-induced Jak kinase activation useful in the methods of the invention are also provided. Antibodies raised against peptide fragments of Jak1, Jak2, and Tyk2 kinase capable of specifically binding to these Jak kinases without interfering with kinase activity are also provided. In addition, the complete DNA coding sequence and amino acid structure of Jak2 kinase is provided by the invention.

Title: Laminated films
Inventor: RASMUSSEN OLE-BENDT
IPC: B29C49/00
Filed: 1993-01-28
Abstract: A cross laminate of two films, each of which is uniaxially or unbalanced biaxially oriented, the films being arranged so that the major axes of orientation criss-cross each other (steps 1 to 3), is treated in a calendering process in which machine direc-tion ribs are formed which are thicker than the sheet between the ribs and which have a configuration which confers increased re-sistance to bending over a line perpendicular to the rib. The ribs are formed by a combination of passage between grooved rollers ("lateral calendering") (steps 4 and 6), the grooves of which include inclined walls on opposing grooves between which the mate-rial of the laminate is squeezed, longitudinal stretching (step 5) and heat treatment (step 10). In a preferred process a sandwich of two cross-laminates is subjected sequentially to passage between a first set of grooved rollers (step 4), longitudinal stretching (step 5) and passage through a second set of grooved rollers (step 6) in which the undulations created in the first set of rollers are regis-tered with the second set of grooved rollers, followed by heat treatment (step 10), for instance an ironing process. The cross sand-wich is then cooled (step 11) and separated into two cross laminates (step 12).

Patent CA-2138714-A1 (CA)
Title: Log Splitter
Inventor: GREEN ROBERT H
IPC: B27L7/00
Filed: 1994-12-21
Abstract: An improved hydraulic log splitter which includes a hydraulic reservoir formed integrally with a frame of the log splitter.  Hydraulic fluid from the reservoir is supplied by a pump to a control valve. A fluid passage is open through the control valve to a hydraulic intensifier which includes a cylinder and a piston extendable from the cylinder.  The piston pushes a log against  a stationary splitting wedge.  The piston is urged toward a retracted position by a return spring internal to the cylinder.  When the control valve is in other than an "extend" position, hydraulic fluid supplied to the control valve is allowed to flow into a return conduit back to the reservoir.  In this condition, the pressure the hydraulic fluid develops insufficient force to overcome the force exerted by the return spring, and the ram remains retracted.  When the control valve is placed in the "extend" position, fluid that flows to the return conduit is blocked and the pressure in the hydraulic intensifier rises to overcome the force of the spring and advance the ram.  A log placed on the splitter is thus driven by the piston to be split by the wedge.  The wedge is designed to force the log against guide rails during splitting.
