Abstract: Regarding a base construction comprising a hot plate for a coffee-making apparatus of the type designed to have water brought to a boil in a closed container (1), whereupon the water is pressed through a riser pipe (12) into an open container (6), where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container (1) through a filter placed at the outlet of the open container, the objective is to provide a sealed base construction which comprises a hot plate for a coffee-making apparatus where the hot plate does not suddenly boil dry, while the finished coffee beverage is carefully treated. Moreover, a reliable sealing of the hot plate must be provided, using simple means and without the use of tools. According to the principles of the present invention, this objective is met by placing the hot plate and the inside bottom of the closed container in a position where the normal of the hot plate and/or the inside bottom is at no point vertical during boiling.

Patent CA-2402428-A1 (CA)
Inventor: BABITCH DANIEL
IPC: H04B7/00
Filed: 2001-05-31
Abstract: A wireless transceiver featuring a compensating filter circuit (17) with a frequency and optionally an amplitude response which has the same function as the composite of filter effects from the transmit side (15) as well as from the intermediate frequency (IF) stage of the receive side (13). The compensating filtering approximately duplicates the effects of the phase lock loop on the transmit side and the effects of IF filtering on the receive side, as well as amplitude distortion in the detector, which would delay or distort the audio. Then, the compensated audio is added or subtracted, depending on phase considerations, from the receive signal so that the receive signal is free of filter artifacts.

Title: System and method for distributed monitoring using remote sensors
Inventor: CHRISTIAN SEAN
IPC: H04M11/00
Filed: 2001-04-25
Abstract: A system for gathering, transmitting, and storing data captured from remote monitoring sites positioned in the field. The system has specific applicability to distributed chemical sensing and reporting, and distributed power monitoring and reporting. Data from Transducers monitoring water quality parameters or electrical power parameters is transmitted to the Internet or Intranet via a communications link. Such data is relayed to secure servers, where it is formatted, analyzed, and stored for customer retrieval. If alarm conditions exist that require immediate customer notification, such notifications are sent to a customer via one or more telecommunications means, including pager, cellular telephone, or email. With respect to the distributed chemical sensing embodiments, the invention preferably utilizes fiber optic chemical sensors that address the problem of biofouling. Using anti-fouling measures, the invention can provide continuous, long-term waterway monitoring.  With respect to distributed power monitoring and reporting, the invention preferably utilizes a fiber optic current transducer system to measure magnetic fields in electric power and power electronic applications. Such transducers are based upon rare-earth iron garnet (REIG) crystals that exhibit the Faraday effect when placed in a magnetic field. In both cases, respective sensor technologies can be coupled with wireless or wired telecommunications and network infrastructures, thereby allowing businesses to shift from a reactive to a proactive mode of monitoring and operation.

Abstract: The present invention provides an apparatus and method for stabilizing a joint between two sections of corrugated pipe. A first section of corrugated pipe is associated with a second section to form a joint. The first embodiment includes one flexible member with two ends. The flexible member is looped around the first section of pipe, secured against a corrugation, and the two ends are associated and tightened.  A section of the flexible member is left as a tail which is then stretched across the joint, looped around the second section of pipe, secured against a corrugation, then brought back a second time across the joint and cinched to the other end of the flexible member such that an axially aligned support is formed.       In the second embodiment, a second flexible member is used and two axially aligned supports are formed. A tail portion of each flexible member is left unrestrained. Each tail is then stretched across the joint, threaded between the other flexible member and pipe, brought back across the joint, and cinched forming two axially aligned supports.

Abstract: The present invention relates to a tip assembly to form a smooth transition between (a) an overhead electric line against which a current collector runs and rubs to collect current from the overhead line, and (b) a line junction hardware mounted at a junction point of the line. An elongated wear sheath having a U-shaped cross section defines two longitudinal side walls and a longitudinal bottom wall, the longitudinal bottom wall having an inner line-receiving concave face and an outer current collector running and rubbing convex face. An elongated line retainer having a longitudinal line-engaging concave face is structured to fit between the two longitudinal side walls with the longitudinal line-engaging concave face turned toward the inner line-receiving concave face. At least one mechanical fastener is used to secure the elongated line retainer between the two longitudinal side walls. In operation, the inner line-receiving concave face is applied to the overhead line, the elongated line retainer is placed between the two longitudinal side walls with the longitudinal line-engaging concave face applied to the line, and the elongated line retainer is secured between the two longitudinal side walls by means of the at least one fastener to thereby firmly hold the overhead electric line within the tip assembly. The elongated wear sheath has a distal end, the outer current collector running and rubbing convex face tapers toward the distal end, and the longitudinal bottom wall defines, at this distal end, a V-shaped slot through which the line extends. The tapered outer convex face defines with the V-shaped slot the smooth transition between the overhead line and the junction hardware.
