Patent CA-2283398-A1 (CA)
Inventor: STEVENS TODD A
IPC: B29C65/74
Filed: 1998-03-03
Abstract: A package is provided with a lid and container that are heat sealed together. A multi-ply sheet material is provided for being thermoformed to define the container which has a tapering wall and bulge-resistant bottom end. Prior to thermoforming the container from the sheet, the sheet is heated with oval pads on a plurality of plates which are arranged in a configuration to facilitate control of the sheet temperature. A plug is used in the thermoforming process to contact the sheet and position the sheet within a die. A lid sheet is heat sealed to the container sheet over the thermoformed containers so as to produce a pair of spaced-apart, annular bead heat seals. The package is completed by severing the sealed-together sheets at the periphery of the container with a punch and die set that produces a clean, smooth cut surface.
Patent CA-2285558-A1 (CA)
Inventor: TAMURA SHINICHIRO
IPC: G11B7/24
Filed: 1998-04-08
Abstract: An optical recording medium having a structure that a recording layer containing organic coloring matter and a reflecting layer are sequentially formed on a light-transmissive substrate thereof so that an information signal is recorded/reproduced when the optical recording medium is irradiated with a laser beam made incident on the light-transmissive substrate, the optical recording medium incorporating: a light absorbing layer which is formed more adjacent to an incident point of the laser beam as compared with the reflecting layer, through which the laser beam passes and which absorbs light in an absorption wavelength region for the recording layer. Photo-deterioration of the recording layer composed of organic coloring matter occurs owing to a portion of natural light which has the wavelength which exists in the absorbing wavelength region for the organic coloring matter. In the optical recording medium having the above-mentioned light absorbing layer, natural light made incident on the reflecting layer is shielded by the reflecting layer. Therefore, the recording layer is not irradiated with natural light. A portion of light of natural light made incident on the substrate which has the wavelength which exists in the absorbing wavelength region for the organic coloring matter is absorbed by the light absorbing layer and, therefore, attenuated. As a result, the quantity of light with which the recording layer is irradiated can be reduced.

Patent CA-2291716-A1 (CA)
Inventor: MCINNES MALCOLM BICKNELL
IPC: E21B4/14
Filed: 1998-05-26
Abstract: This specification relates to a percussive hammer, and in particular to a piston working in conjunction with a spigot for controlling air flow to the piston. The invention comprises a hammer barrel (11) that is adapted for connection at its upper end to a source of high pressure fluid, a drill bit (12) held in the lower end of the hammer barrel (11), a spigot (25) located in and extending axially within the hammer barrel (11) for control of the high pressure fluid, and a piston (14) slidably located within the hammer barrel (11) so that it is able to reciprocate between the spigot (25) and drill bit (12). The upper end of the piston has a bore (16) that co-operates with the spigot (25). The spigot (25) has an opening (36) and the piston (14) has a transfer port (37) which directs air flow around the piston (14). The spigot (25) in combination with the bore (16) forms a sealed chamber which is used to force the piston (14) downwardly to impact against the drill bit (12). The construction greatly simplifies the assembly of the hammer and results in components which are more easily produced by comparison to currently available percussive hammers.

Inventor: FUNYAK DAVID C
IPC: H01R4/30
Filed: 1999-12-14
Abstract: A terminal connection for a flat stab of an electrical terminal includes a spring clip which retains a nut in alignment with an aperture in the flat stab. The spring clip is fabricated from a strip of resilient electrically conductive material and has a top wall with a central aperture, side walls extending downward from the top wall and having slots therein, and outwardly projecting flanges on the bottom edge of each of the side walls. A square nut is retained in the spring clip by lateral projections on the nut engaged in the slots in the side walls with the tapped hole in the nut aligned with the aperture in the top wall of the clip. The fastener assembly clips onto the end of the flat stab which is in a recess in the electrical terminal, with the stab between the nut and the top wall of the spring clip.  The outer edges of the flanges on the spring clip frictionally engage against the opposite sides of the recess in the terminal to retain the spring clip and nut in the terminal until a screw is passed through the apertures in the top wall and the flat stab engages the nut to secure a conductor to the stab. The slots in the side walls of the clip prevent rotation of the nut and provide positive stops which resist loss of the nut through application of excessive axial force to the screw.

Patent CA-2302466-A1 (CA)
Inventor: TRANS FRANCOIS
IPC: H04L25/08
Filed: 1998-07-31
Abstract: Nodes on a network are synchronized with each other using a clock transfer system (16). The communications channels between the nodes are then measured (164) and calibrated (163) for optimal bandwidth. The optimized channels and synchronization enable a new form of signaling based on precise control of the frequency, amplitude, and phase of the waveform of the signal. Receiving nodes receive information in order to locate the signal at the frequency, phase and amplitude. Precision control (165, 166) of these parameters also serves as a unique signature of the transmitting node preventing security breaches (162) as the signal's characteristics are unique to the transmitting node. The channel is continuously updated with a precision control system (165, 166) to insure that the nodes are not out of phase.

Title: Slurry hydrocarbon synthesis with reduced catalyst attrition and deactivation
Inventor: COULALOGLOU CONSTANTINE ANASTA
IPC: C07C1/04
Filed: 1998-10-16
Abstract: A slurry hydrocarbon synthesis process with reduced catalyst attrition is achieved by injecting a synthesis gas comprising a mixture of H2 and CO up into the reactive slurry with a gas distribution grid (106) having gas injectors (10) horizontally arrayed across, and vertically extending through, an otherwise gas and liquid impervious plate (32).

Title: Method for manufacturing poly(hexamethylene adipamide) from monomethyladipate and hexamethylenediamine
Inventor: MARKS DAVID NEIL
IPC: C08G69/00
Filed: 1998-12-17
Abstract: An improved method for manufacturing poly(hexamethylene adipamide), i.e. nylon 6,6, by resting monomethyl adipate with hexamethylenediamine in an approximately equimolar ratio in the presence of water at a temperature of 100 to 165 °C while simultaneous distilling off of a stoichiometric amount of methanol. The resulting aqueous intermediate product is then heated to 200 to 260 °C while distilling off substantially all water at a pressure of 1.50 to 250 psig (1.03 × 10 6 to 1.72 × 10 6 Pa) followed by reducing the pressure to atmospheric pressure and increasing the temperature to 270 to 280 °C to polycondense the distillate residue. Such a process is useful in producing high purity commercial grade poly(hexamethylene adipamide) that advantageously avoids problems caused by N-methylation of the polyamide.
