Title: Method for coating using molten organosiloxane compositions
Inventor: CIFUENTES MARTIN E
IPC: C09D183/04
Filed: 1994-06-07
Abstract: Organosiloxane compositions comprising specified combinations of MQ resins and liquid polyorganosiloxanes are applied as molten materials to form coatings that are non-flowable under ambient conditions and that can initially be remelted by heating the coating above its flow transition temperature. In the presence of moisture, the flow transition temperature of the coating gradually increases due to the reaction of hydrolyzable groups on the polyorganosiloxane ingredient until the coating is converted to a non-flowable, resin reinforced elastomer. Preferred coatings are non-transferable at 25°C. within ten minutes following application.
Patent CA-2127311-A1 (CA)
Inventor: LITTLEJOHN MARK
IPC: B65D21/02
Filed: 1994-07-04
Abstract: ABSTRACT A food container which is a combination of a base portion and a lid portion made from a resilient polymeric material is disclosed. The base is a unitary component including an upwardly projecting, peripherally extending sealing rim having inner and outer sealing areas. The lid is also a unitary component including a peripherally extending sealing channel correspondingly shaped to receive the sealing rim of the base and particularly, to engage the rim at the inner and outer sealing areas. Because both the base and lid are made from resilient material, the inner and outer sealing areas are shaped to provide a self-reinforcing seal configuration wherein the initial engagement of either the inner or the outer seals urges the other seal into engagement. This feature also permits a wide tolerance to processing variations in the size of the lid and the base. The base portion of the food container of the present invention is also designed to include audible indicators as the lid becomes fully sealed with the base. Further, the container is suitable for microwave cooking.

Patent CA-2130897-A1 (CA)
Title: Data compression using hashing
Inventor: GRAYBILL MARK D
IPC: H03M7/30
Filed: 1992-12-23
Abstract: Compressing a sequence of characters drawn from an alphabet uses string substitution with no a priori information. An input data block is processed into an output data block comprised of variable length incompressible data sections and variable length compressed token sections. Multiple hash tables are used based on different subblock sizes for string matching, and this improves the compression ratio and rate of compression. The plurality of uses of the multiple hash tables allows for selection of an appropriate compression data rate and/or compression factor in relation to the input data. Using multiple hashing tables with a recoverable hashing method further improves compression ratio and compression rate. Each incompressible data section contains means to distinguish it from compressed token sections.

Patent CA-2140932-A1 (CA)
Title: Lightning protection system
Inventor: BRIET RICHARD
IPC: H02G13/00
Filed: 1993-07-23
Abstract: 2140932 9402980 PCTABScor01 Disclosed is a lightning attractor apparatus for protecting secondary structures within the lightning protection zone of said lightning attractor apparatus, which is electrically grounded to the body of earth and ground water having reference potential. The apparatus includes a central conductive rod, one or more coaxial cylindrical conductors of decreasing height with the lowest cylindrical conductor on the outside, and a conducting base means onto which all above-ground conductors are rigidly mounted, and which provides the link with a common grounding rod. The grounding rod provides the electrical connection of the apparatus with the reference ground potential. Insulative concentric spacers, located at more or less regular intervals along the axis, separate and isolate the above-ground conductors from one another, their separation being such that arc-over between adjacent conductors are effectively suppressed. An insulating covering for the lower portion of the outer cylindrical conductor provides protection by preventing direct contact with current carrying surfaces when lightning strikes the apparatus. A separately grounded conducting annular ring at the base of the tower, extending typically a few inches above the surface, prevents intercepted lightning currents form leaving the immediate area laterally below the apparatus beyond the perimeter of the ring, thus eliminating step potentials in the region outside the base annular ring. The outside cylindrical conductors provide EMI/RFI shielding for intercepted lightning currents that pass through inside conductors. In one aspect of this invention, one or more cylindrical conductors may be individually grounded to reference ground potential.

Title: Mode-locked fiber ring laser
Inventor: PFEIFFER THOMAS
IPC: H01S3/106
Filed: 1995-06-28
Abstract: A passively mode-locked fiber ring laser (LAS) is disclosed for generating optical pulses whose repetition frequency is settable. The mode-locked fiber ring laser (LAS) contains an erbium-doped fiber (ER), a ring resonator (RES), a pump-light source (PUMP), an optical modulator (MOD), and a feedback loop (RS). A portion of the signal light, which is produced by stimulated emission and is composed of a plurality of pulse repetition frequencies, is processed in the feedback loop ( RS) into a drive signal which is coupled to the control input of the optical modulator (MOD). The feedback loop ( RS) includes an adjustable filter which filters the desired pulse repetition frequency from the signal light. Thus, optical pulses of a given repetition frequency are developed in the ring resonator ( RES) and at the output (OUT) of the passively mode-locked fiber ring laser (LAS).
