Patent CA-2232729-A1 (CA)
Inventor: MERCER ROBERT E
IPC: E05B73/00
Filed: 1998-03-19
Abstract: The invention relates to security apparatus for computer equipment and, more particularly, to a device for securing a computer casing and its contents, i.e. the CPU, to a surface to prevent its theft and/or to prevent tampering with or pilfering of its internal components. The device comprises an open-ended base (12) which is mountable on a surface by fasteners such that the unfastening elements therefor are contained generally within the base. A containment structure (14) comprising a frame (18) and a plurality of connecting members (20a, 20b, 20c, 20d) is fastenable to the base by fasteners whose unfastening elements therefor are likewise contained within the base. The containment structure prevents the CPU (16) from being removed from the base in at least two directions, namely a direction substantially perpendicular to the base on account of the frame and in lateral directions due to the location of the connecting member pairs (20a, 20c and 20b, 20d) at the sides of the CPU. When the CPU is positioned within the containment structure, access to the unfastening elements is restricted by a pair of cover plates (102, 104) which cover the open ends (22, 24) of the base and which are lockable together in this position. The locking mechanism consists of a connecting rod attached to one of the cover plates. The opposite end of the rod is adapted to be lockingly received in a lock chamber affixed to the other cover plate.  Each cover plate includes a tab (112, 114) which abuts the respective front or rear face of the CPU to prevent its removal from the containment structure in the longitudinal direction, i.e.  between the front or rear pairs of connecting members (20a, 20b or 20c, 20d). The distance between the tabs is variable because the effective length of the connecting rod is variable and, hence, the device can accommodate CPU's of varying depths. The frame is adjustable to accommodate CPU's of different depths and is adapted to be arranged in several different configurations, one of which compensates for variations in the width of the CPU while another provides a back-up deterrent against easy removal of the CPU in the longitudinal direction in the event the cover plate lock mechanism is defeated.

Title: Safety locking mechanism for a mechanical lifting jack
Inventor: BOULANGER DAVID M
IPC: B66F1/06
Filed: 1998-04-15
Abstract: A mechanical lifting jack with a locking mechanism that arrests upward motion of the handle if the handle is suddenly released by the operator while raising or lowering a load. A latch on the pivot attachment of the handle to the lifting assembly is actuated by a lever disposed at the distal end of the handle, and engages into a toothed safety link when the lever is released. In the event that the operator suddenly releases the handle accidentally, the latch engages the safety link to arrest the upward motion of the handle. The invention can also be used to lock the handle into an upright position alongside the vertical support for compact storage.
Patent CA-2235085-A1 (CA)
Inventor: NENNIGER JOHN
IPC: E21B43/24
Filed: 1998-04-17
Abstract: A method and apparatus for stimulating heavy oil production from an oil bearing formation. The method includes the steps of placing a downhole heater in the formation adjacent to the oil producing zone to heat heat transfer fluid and then energizing the downhole heater. The method further includes the step of passing the heat transfer fluid through the heater to heat the heat transfer fluid and then injecting the heat transfer fluid into the oil bearing formation. This brings the heated fluid into contact with the oil to increase the flowability by decreasing the effective viscosity of the oil. In this manner, an oil extraction chamber can be quickly formed in the oil bearing formation. In another aspect of the invention, the apparatus, includes a source of energy and flow through heater connected to the source of energy. The flow through heater is attached to the end of coil tubing, and placed downhole. The apparatus further includes a control system for monitoring the heater, a source of injection fluid, a pump to inject the injection fluid and a pressure reducer on the exit of the heater, to maintain fluid pressure in the heater for efficient heat transfer.

Title: Chemokine receptor antagonists and chemotherapeutics
Inventor: GIONG JIANG-HONG
IPC: C07K14/715
Filed: 1998-08-14
Abstract: Peptides corresponding to the N-terminal 9 residues of stromal cell derived factor-1 (SDF-1) have SDF-1 activity. SDF-1, 1-8, 1-9, 1-9 dimer and 1-17 induced intracellular calcium and chemotaxis in T lymphocytes and CEM cells, and bound to CXC chemokine receptor 4 (CXCR4). The peptides had similar activities to SDF-1, but were less potent. Whereas native SDF-1 had half maximal chemoattractant activity at 5 nM, the 1-9 dimer required 500 nM and was therefore 100 fold less potent. The 1-17 and a 1-9 monomer analog were 4- and 36-fold, respectively less potent than the 1-9 dimer. Both the chemotactic and calcium response of the 1-9 dimer was inhibited by an antibody to CXCR4. The basis for the enhanced activity of the dimer form of SDF-1, 1-9 is uncertain but it could involve an additional fortuitous binding site on the 1-9 peptide in addition to the normal SDF-1, 1-9 site. A 1-9 analog, 1-9[P2G] dimer, was found to be a CXCR4 antagonist. Overall this study shows that the N-terminal peptides are CXCR4 agonists or antagonist and these could be leads for high affinity ligands.

Abstract: A wind driven flying toy comprising a single guideline and an aerodynamic body slidably secured to the guideline, the aerodynamic body being capable of traversing the entire length single guideline in both directions by reacting with the action of wind power member even when the wind power is in a constant wind direction. The direction of the travel of the aerodynamic body can be modified by adjusting the orientation of the aerodynamic body and is not dependent upon a change in the direction of the wind. In addition, the direction of travel of the aerodynamic body along the single guideline can be reversed by rotation of a handle connected to the end of the guideline when the aerodynamic body is in contact with the handle. The aerodynamic body can take a variety of forms, including that of a unitary structure provided with apertures for slidably securing it to the guideline, a sail structure sail element having eyelets or guidetubes for slidably securing to the guideline, or the aerodynamic body can include a sail structure having a sail element secured to a frame element. The flying toy can also be automated by connecting rotating devices to the ends of the guideline.
