Patent CA-2281732-A1 (CA)
Title: Hot channel stopper
Inventor: GUENTHER HERBERT
IPC: B29C45/27
Filed: 1999-09-09
Abstract: Plugs (20) that can be removed and that are made in two parts are used to close off channel sections in a hot runner manifold (10); these are arranged so as to subtend an acute angle .alpha. with the principal axis (A) of a runner or channel (15) that can be charged with a plastified mass. A continuous sealing edge of the front surface (30) of these is pressed onto a continuous annular surface (40) that encloses an opening (42) to the channel (15). The angle .alpha. lies between 40° to 45°. The plug (20) incorporates a pressure piece (26) that is located in front of a screw body (22) that can be screwed into an inclined bore (15) that opens out into area of the channel in the manifold (10) that is to be sealed off. At the sealing edge (31), the front surface (30) of the plug is flat, although it can be concavely curved inward or be crowned (32), much like a segment of a sphere, the diameter of which is defined by the diameter of the smallest radius of the sealing edge (31). The outer annular surface (40), which is circularly restricted, can be arranged on an elbow (38) at which the channel (15) makes the transition to become a branch of the manifold (10). In a through channel (15) with a series of branches (34) selected sections (36)--the ends of which have annular surface (40) that are inclined opposite to each other-- can be closed off by the associated plugs (20).

Filed: 1999-02-18
Abstract: L'invention concerne un équipement permettant de traiter par fermentation des déchets organiques contenant une grande quantité d'eau, par exemple des ordures ménagères, tout en conservant des conditions propices à la fermentation. L'invention concerne en particulier un équipement de traitement par fermentation de déchets organiques comprenant un conduit d'alimentation en vapeur (3), relié à la chemise (2) d'une cuve de fermentation (1) par l'intermédiaire de détendeurs de pression (17, 18) et d'une pompe à vide (4), elle-même reliée à la partie inférieure de ladite chemise (2) par un trajet de communication (27). La vapeur détendue à moins de 100 ·C arrive alors dans la chemise (2), permettant ainsi de traiter par fermentation les déchets contenus dans ladite cuve de fermentation (1), grâce à la chaleur de condensation de la vapeur. Une unité d'alimentation en air (36) permet par ailleurs de fournir de l'air conditionné selon une certaine humidité à la cuve de fermentation (1).

IPC: H04B10/50

Abstract: A new method is described for the automatic restart of optical transmitters in a fiber optic cable system. Said restart follows the automatic shut-down of the transmitters themselves as a consequence of a fault. The method in accordance with the present invention comprises the steps of periodically sending over the system, by means of a transmitter, a restart pulse and wait for such pulse, which is received/retransmitted by further receivers/transmitters to come back, within a given time interval, to the transmission point and is characterized in that it further comprises the step of increasing the restart pulse duration by a certain amount whenever it is received/retransmitted. Thus, the method in accordance with the present invention is independent of the delays introduced along the optical link because of the introduction of additional equipments (namely WDMs) and moreover it permits of more easily remaining within the imposed safety limits concerning the initial short duration of the pulse.

Abstract: The printed circuit board zero-force plug connector has a mechanism whose operation causes the plug connector to move between a fitting position (open) and a connected position (closed). The fitting position allows the insertion or removal of a printed circuit board, which makes contact correctly with the printed circuit board. The mechanism of the zero-force plug connector assembly is operated by a rotary movement of an operating member, and/or the mechanism is configured such that it starts to move the printed circuit board zero-force plug connector to the connected position only after it has locked the printed circuit board in its correct position. The printed circuit board is released from the lock only after the mechanism has caused the printed circuit board zero-force plug connector to assume its fitting position.

Title: Flexible frequency-time division duplex in radio communications systems
Inventor: LENZO MICHAEL
IPC: H04W92/10
Filed: 1998-11-13
Abstract: A flexible channel architecture supports full-duplex, radio-frequency communication between a base station, such as a PWT or DECT base station, and a group of remote terminals. Downlink communication from the base to the terminals is by way of a first radio-frequency carrier, and uplink communication from the terminals to the base is by way of a first radio-frequency carrier, and uplink communication from the terminals to the base is by way of a second radio-frequency carrier. Each carrier is organized to provide an N-timeslot time-division multiple access data stream (N an integer), so that together the two carriers provide a 2N-timeslot system.  Within each frame, data from the base to a terminal is sent on the first carrier during a first time slot, and data from the terminal to the base is sent on the second carrier during a second time slot, the first and second time slots being offset by a time offset which can vary across communications links. The disclosed system provides a unified architecture which allows a single time-division multiple-access hardware platform to efficiently and selectively support either time-division duplex or frequency-division duplex.
