Abstract: A circular saw having an improved line-of sight. The circular saw comprises a motor for rotatably driving a saw blade about an axis to cut a workpiece, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece; a housing supporting the motor; a shoe plate supporting the circular saw on the workpiece to be cut, the shoe plate being pivotably connected to the housing to adjust the bevel angle; a main handle supported by the housing; an auxiliary handle supported by the housing; and an indicator for indicating the bevel angle. Preferably, the main handle, the auxiliary handle and the indicator are arranged so that, in the cutting position, the operator can view the saw blade as the saw blade cuts the workpiece and can view the indicator. The operator holds the main handle with one hand and the auxiliary handle with the other hand. When the operator holds the auxiliary handle with the other hand, the operator's other hand and the auxiliary handle do not obscure the operator's view of the saw blade as the saw blade cuts the workpiece.

Patent CA-2286301-A1 (CA)
Inventor: ZWICK MICHAEL BRUCE
IPC: C12N15/10
Filed: 1999-11-01
Abstract: The filamentous bacteriophage is a common immunogenic carrier for generating anti-peptide antibodies against recombinant peptides displayed on its surface. For immunizations, peptides are displayed as fusions to either the minor coat protein, pIII, or, more commonly the major coat protein, pVIII. Phage displaying a poorly expressed malarial peptide on pVIII  were compared to phage bearing the same peptide on pIII , and to phage that were chemically coupled to a synthetic version of the peptide using the crosslinker, sulfo-succinimidyl 4-(N-maleimido-methyl)cyclohexane-1-carboxylate (sulfo-SMCC) for their ability to induce an anti-peptide Ab response in mice. We also included in this comparison the same peptide displayed as a recombinant fusion to the maltose-binding protein (MBP) of Escherichia coli, as well as the synthetic counterpart as chemically crosslinked to MBP with sulfo-SMCC. The results demonstrate that only the chemically-crosslinked conjugates elicited a strong anti-peptide antibody response by ELISA, probably due to the higher number of peptides that were displayed by the phage and MBP conjugates as compared to their recombinant counterparts.  The amount of peptide that was covalently linked to the phage was increased approximately two-fold when a lysine residue was engineered near the N-terminus of mature pVIII. The ease of chemically conjugating synthetic peptides to phage, and of modifying pVIII by genetic engineering, suggests new roles for the filamentous phage in vaccine studies.

Patent CA-2288410-A1 (CA)
Inventor: YOUNG DAVID A
IPC: F16H61/40
Filed: 1999-11-03
Abstract: A system is provided for lubricating and cooling a remote drop box for a hydrostatically driven four wheel drive tractor. The hydrostatic motor is operated very close to its maximum rated operating speed during roading in order to maximize drawbar pull and road speed capability for a variable hydrostatic motor, leaving very little margin for overspeeding that occurs when the tractor is roading downhill. An electronic overspeed control is provided to provide dynamic engine braking.      When the hydrostatic drive is used with a high torque engine, the available charge pump flow drops as the engine speed drops, and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition is alleviated by the supplemental charge flow system.      Stabilization of the load sensing hydraulic system, which is subject to rhythmic flow pulsations or surging, particularly when flow compensators in valuing interact with the flow compensator of the hydraulic pump, is accomplished with an attenuator/hose assembly.

Filed: 1998-03-10
Abstract: Flashing footwear includes at least one light source, e.g., an LED (12A), located on an external surface of the footwear so as to be visible, such as the rear of the heel. A power source, such as a battery (28), provides sufficient power to light the light source to cause illumination in response to a switch (26) actuated by the condition of motion of the footwear so as to change between open and closed positions. A circuit is combined with the battery (28) and switch (26) to form a module arranged in the heel of the footwear. This circuit directs power from the battery (28) to the LED (12A, 12B, 12C) to cause the LED (12A, 12B, 12C) to illuminate for a period of time in response to a change of the switch (26) from the closed position to the open position and/or to light continuously while the switch (26) is closed.

The tray (16) is biased to return to its rest position.  The lid (24) and tray (16) are operatively associated such that as the lid is opened from a closed position, the tray (16) is moved from a storage position within the receptacle (11) to its rest position. The tray (16) is foldable to facilitate its storage within the receptacle (11) upon closing the lid (24).

Title: Generation of repeatable cryptographic key based on varying parameters
Inventor: WETZEL SUSANNE GUDRUN
IPC: H04L9/28
Filed: 2000-03-28
Abstract: A repeatable cryptographic key is generated based on varying parameters which represent physical measurements. Locations within a share table, which locations store valid and invalid cryptographic shares, are identified as a function of received varying parameters. The share table is configured such that locations which are expected to be identified by legitimate access attempts contain valid cryptographic shares, and locations which are not expected to be identified by legitimate access attempts contain invalid cryptographic shares. The share table configuration may be modified based on prior history of legitimate access attempts.    In various embodiments, the stored shares may be encrypted or compressed. A keystroke feature authentication embodiment uses the inventive techniques to implement an authentication system which authenticates based on an entered password and the manner in which (e.g. keystroke dynamics) the keystroke is entered. Another embodiment uses the inventive techniques to protect sensitive database information which is accessible using DNA measurements.
