Patent CA-2182409-A1 (CA)
Inventor: CHAWLA MANMOHAN S
IPC: F42B1/028
Filed: 1996-07-26
Abstract: A shaped charge for efficiently transferring energy from an explosive material to create a jet while reducing the effect of shock reverberations on the jet. The shaped charge incorporates a first liner adjacent the explosive material and a second liner having a hollow center. The combination of two liners reduces the effect of shock reverberations on the charge, thereby increasing thejet's cohesiveness and target penetration capability. The first and second liners can be formed as a single liner having at least two liner elements extending outwardly from the liner apex. Multiple liners can be similarly placed adjacent to the other liners in a cascading fashion, or a gap can be incorporated betweenadjacent liners. A shock absorbing material can be positioned between liners to further attenuate the shock reverberations. Alternatively, such gap can be filled with an explosive material to increase the jet mass. The first liner can be smaller than the second liner to produce a segmented pulse in the jet.

Title: Dry household lubricant
Inventor: MAPLES PAUL D
IPC: C10N50/08
Filed: 1995-03-08
Abstract: A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces of a bicycle chain and other similar low-speed and low-temperature mechanisms operating in a dusty environment. The lubricant comprises an insoluble soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax and Petrolatum. After application and evaporation of the solvent, the composite dry lubricant exhibits good penetration and load-bearing properties without the dirt-retaining character of greases. The undissolved particles of soap combine with dirt particles to break down portions of the lubricant into a dry flaky dust which is sloughed off the mechanism.

Title: Compositions comprising dna damaging agents and p53
Inventor: ROTH JACK A
IPC: A61K33/243
Filed: 1995-04-24
Abstract: The present invention relates to the use of tumor suppressor genes in combination with a DNA damaging agent or factor for use in killing cells, and in particular cancerous cells. A tumor suppressor gene, p53, was delivered via a recombinant adenovirus-mediated gene transfer both in vitro and in vivo, in combination with a chemotherapeutic agent, Treated cells underwent apoptosis with specific DNA fragmentation. Direct injection of the p53-adenovirus construct into tumors subcutaneously followed by intraperitoneal administration of a DNA damaging agent, cisplatin, induced massive apoptotic destruction of the tumors. The invention also provides for the clinical application of a regimen combining gene replacement using replication-deficient wild-type p53 adenovirus and DNA-damaging drugs for treatment of human cancer.

Title: Automated Branch Flow Calibration in a HVAC Distribution System
Inventor: AHMED OSMAN
IPC: F24F11/00
Filed: 1997-02-20
Abstract: A HVAC system automates the process of calibrating the individual branch flows of the system. For each branch of the system, a damper is closed and flow values at the output of the prime mover and at the input of the damper are measured. The damper is then opened 50% and again flow values at the output of the prime mover and at the input of the damper are measured. A flow coefficient, which correlates the flow difference measured at the output of the prime mover with the flow difference measured at the input of the damper, is then determined. The flow through each damper of each branch is calibrated in this manner, resulting in an overallbalancing of the HVAC system. The automated process of branch flow calibration eliminates the tedious and time consuming process of both manual steps of measuring the branch flows and determining the flow coefficients as was performed in the prior art.

Title: Method to manufacture reinforced axi-symmetric metal matrix composite shapes
Inventor: BEDDOES JONATHAN C
IPC: B22D29/00
Filed: 1997-04-07
Abstract: A composite part consisting of a metallic matrix and reinforcing fibres is fabricated by the simultaneous winding of the fibre and plasma spraying of the matrix onto a rotating mandrel, wherein an axi-symmetric part is produced with multiple layers of the fibres aligned in the circumferential direction. Single or multiple fibre strands are wound onto a mandrel and simultaneously sprayed with the heated powder matrix material using a thermal spray process. Rotation and translation of the mandrel produces an axi-symmetric composite part. The content of the fibre material in the plasma sprayed matrix is typically up to 40% by volume. The light-weight composite part is produced in a single processing step. The part may be used either directly, or as an insert in other components with or without further densification.

Filed: 1997-08-29
Abstract: A method for coupling a liquid jet head unit is to couple a liquid jet head unit for recording by discharging liquid to a recording medium with a head installation member capable of installing the head unit through an elastic member.  This method comprises the steps of preparing a liquid jet head unit structured integrally with two orifice arrays substantially paralleled and a first supply opening group for supplying liquid to the orifice arrays, and a head installation member provided with a second supply opening group corresponding to the first supply opening group for supplying liquid to the liquid jet head unit, and also, an elastic member having holes corresponding to each of the supply opening groups, providing first and second coupling units for one end side and the other end side of the two orifice arrays for coupling the liquid jet head unit and the head unit installation member, respectively and coupling only one face of the liquid jet head unit and the head unit installation member using the first and second coupling units.  With the adoption of this method, it is possible to implement stabilized recording on a recording medium by means of stabilized ink supply, at the same time, preventing any erroneous installation in the coupling mode.
