Patent CA-2251830-A1 (CA)
Inventor: GILHOUSEN KLEIN S
IPC: H04B15/00
Filed: 1997-04-15
Abstract: A system and method for reducing radio frequency interference arising in connection with pulsed transmission over time division multiplexed communication channels. In a first embodiment, a subscriber station (300) is nominally assigned all of the slots (TN0-TN7) of each frame of a first transmit channel (R0). By transmitting RF energy substantially continuously, the subscriber station reduces interference arising from pulsed transmission.  In a second embodiment, a subscriber station (300) is nominally assigned one or more slots (TN0-TN7) of each frame of a primary channel (R0) for conventional transmission of useful information, and is also instructed to continuously transmit RF energy over an auxiliary channel (R1) at times other than during the assigned primary channel slots. In this way, interference generated in the vicinity of the subscriber station (300) is reduced due to the substantially continuous transmission of RF energy by the subscriber station (300). More than one subscriber station (300) may simultaneously utilize the auxiliary channel (R1) during reduced interference mode operation.

Abstract: La présente invention se rapporte à des bâtonnets de pommes de terre semi-frits, hydratés et congelés ayant une teneur en eau comprise entre 35 % environ et 55 % environ et présentant, après passage au four, sensiblement la même texture interne et de surface que des pommes de terre frites cuites en friteuse. L'invention se rapporte tout particulièrement à un procédé de préparation de bâtonnets de pommes de terre semi-frits destinés à une cuisson ultérieure de finition au four avant leur consommation. Ledit procédé consiste (a) à frire à moitié les bâtonnets de pommes de terre dans de l'huile à une température comprise entre 270 ·F (132·C) environ et 385 ·F (196·C) environ pendant un laps de temps suffisant pour réduire la teneur en eau des frites semi-cuites à une valeur comprise entre 30 % environ et 50 % environ, (b) à hydrater la surface desdites frites semi-cuites jusqu'à ce que leur poids ait augmenté de 1 % environ à 12 % environ, et (c) à congeler lesdites frites semi-cuites et hydratées. Ces frites semi-cuites, hydratées et congelées possèdent une teneur en eau comprise entre 35 % environ et 55 % environ.

IPC: C12N15/12
Filed: 1997-04-21
Abstract: This invention relates to peptides and peptidomimetic compounds that act as antagonists against G protein-coupled receptors (GPCRs). Novel short peptides, derived from the transmembrane domains of GPCRs, ranging in size from about 1520 amino acid residues, can be used as model peptides (peptide-leads) to design novel peptides and peptidiomimetic compounds that antagonize the activity of the same or closely related GPCRs from which they are derived. A lead peptide which may also be a preferred peptide antagonist for the human .beta.2-adrenergic receptor is NH2-GIIMGTFTLCWLPFFIVNIVH-COOH.

Title: Quick response dry pipe sprinkler system
Inventor: GOLINVEAUX JAMES E
IPC: A62C35/66
Filed: 1998-12-16
Abstract: A gas charged fluid flow line of a dry pipe sprinkler system is continuously monitored to detect rate of loss of pressure (dp/dt). The rate of pressure loss is used to detect whether there is an open sprinkler head in a sprinkler grid of the system. Detection of an open sprinkler head and opening of a dry valve may occur in a matter of a few seconds, allowing for a quick response to a fire condition and accurate discrimination of a pressurized gas leak condition. The system may operate at charge pressures in the range of about 7 psig to about 15 psig.

Abstract: An explosive blast shield has two connected parts, a foraminous inner shield (10) surrounded by an impervious outer shield (20). The inner shield (10) has an open lower end to absorb an explosive blast of water and gas, as from an underwater explosion. The inner shield (10), whose area is about 20 % holes (11), blocks most liquid from entering the space (30) between the two shields, but gas passes readily through the holes (11) to equalize the pressure across the inner shield (10). The shield may include a chimney (40) at the upper end for release of gas and a hold-down to prevent the shield from being blown upward.

Filed: 1999-02-15
Abstract: A multiple peak tent structure which is mechanically simple and easy to assemble. The tent structure of this invention can span relatively large areas without inhibiting mobility under the tent through the use of ground extending support poles. The canopy of the multiple peak tent structure is supported by multiple masts resting on a cable network. The cable network is attached to the upper corners of the frame structure resulting in a tent having no supporting poles that extend to the ground in the covered area. The multiple peak tent structure may be expanded modularly to span larger areas.

IPC: G01L13/00
Filed: 1998-11-16
Abstract: A capacitive pressure transducer (110) includes a conductive diaphragm positioned between pneumatically separated chambers. The diaphragm is fixed and sealingly coupled at its periphery to the peripheral rim (116) of a concave body member. The diaphragm (140) is supported in tension by the peripheral rim (116) of a concave body member.  An electrode assembly (150), supported by the body member (120, 130), establishes a substantially planar conductive surface opposite to and spaced apart by a nominal gap from the conductive diaphragm. The body member includes a yieldable portion that is adapted to radically expand its peripheral rim (116) in response to forces applied to the body member. When the forces are aplied, the body member becomes strained beyond its elastic limit and takes a permanent set whereby the peripheral rim (116) is expanded and the diaphragm becomes tensioned.

Inventor: NG CHU
IPC: H04B10/02
Filed: 1999-10-27
Abstract: An arrangement is provided which detects the loss of a high power signal in an optical transmission path and the loss of supervisory signal power and, in response thereto, automatically invokes a procedure which causes an optical signal source connected to the fiber to reduce the power level at which it is transmitting optical signals over the fiber to a safe level. More specifically, reduction of optical signal power supplied by an upstream network element by a prescribed amount is achieved by automatically controlling the output power level of the upstream network element in response to the detection of both loss of signal power and loss of supervisory signal power at a downstream network element as a result of a fiber cut, open connector, or other potentially hazardous discontinuity.
