Patent CA-2178173-C (CA)
Inventor: SHEA ARTHUR W
IPC: G01F23/62

Granted: 2002-12-17
Abstract: A remote level sensor for a residential fuel oil tank is adapted for a fuel oil gauge with a permanent magnet which changes position with changing fluid levels in the tank. The sensor has a housing with a connector which receives a top portion of the gauge such as to provide an alignment of the sensor with the gauge. The sensor is connected to a telephone line, and makes use of a current from the "tip" and "ring" lines of the telephone connection to supplement the power of an on-board battery. The sensor has multiple reed switches each in a different relative position. The reed switches thus each close when the magnet is in a different position, and thereby close when the fluid in the tank is at a different level. The controller has a sampling routine which responds to the detection of a closure of one of the switches by seizing the telephone line, dialing a central monitoring location and transmitting information to the central location indicating which of the switches was closed. A memory unit is provided in which multiple telephone numbers are stored so that the controller can call a second number when no response is received using a first number.

Abstract: The present invention relates to a packing method in which a material (p) is fed by an opening (4c) for feeding the material to a space (4d) to be packed with said material, and said space is subjected to air tapping, that is, switching of air-pressure from a low air-pressure state to a high air-pressure state alternately, thereby packing the material into the space (4d) at a high packing-density.        The use of air tapping for packing a material into a space makes the packing-density of the material uniform.

Granted: 2009-11-10
Abstract: A plurality of petri dishes (44) or other glass or plastic containers are coated on the inside bottom surface of the containers by passing the containers through a coating or layering apparatus (18). The apparatus includes an indexing conveyor (12) to sequentially pass the open containers through a filling station where an amount of a coating material is applied while tilting the container to one side thereby distributing the material to the entire bottom surface to the container.  The containers are conveyed to an aspirating station (20) to aspirate excess material while tilting the container toward the aspirating nozzle (122). Subsequent to the aspiration step, the containers are tilted in the opposite direction to distribute the material in the container. The material is then dried and the containers stacked and packaged. The coating material includes metal ions such as calcium or other divalent metal ions, in a suitable carrier that is able to bond the bottom inside surface of the container. The coating material forms a dehydrated, solidified layer bonded onto the bottom surface of the container.  The coating material can be a water/agar solution or a plastic resin in an appropriate solvent containing the calcium ions.

Title: Method and system for synchronizing time-division-duplexed transceivers
Inventor: BINGHAM JOHN A C
IPC: H04L5/14
Filed: 1998-11-30
Granted: 2005-12-06
Abstract: Improved techniques for synchronizing transmissions and receptions of a data transmission system utilizing time division duplexing is disclosed. The improved synchronization techniques utilize the time-varying nature of the energy of the received data to obtain synchronization. In one embodiment, an improved synchronization processing (500) measures energy (502) in n consecutive frames of received data. An alignment error estimate is then computed (504) based on the measured energy values for the n consecutive frames. In another embodiment, the improved synchronization technique uses the output signals from a multicarrier modulation unit (FFT unit) and thus provides the ability to avoid frequency tones that are susceptible to RF interference. The improved synchronization techniques can also utilize crosstalk interference levels to obtain synchronization. Remote receivers in the data transmission system are able to synchronize to central transmitters, central receivers in the data transmission system are able to synchronize to remote transmitters, and central transmitters are able to synchronize with one another.

Abstract: A method and apparatus for locating the source of noise ingress into a CATV  system return path (16) by coupling a filter (18, 18') having a passband in the noise frequency bandwidth to the nodes between adjacent return path amplifiers {221, 22m, 22n). T'he filter (18, 18') is sequentially coupled to the nodes, working away from the CATV system headend (30). A signal level meter (50) or the like monitors the effect on the noise of coupling the filter (18, 18') to the nodes. When a node is reached at which coupling of the filter (18, 18') to the node no longer has any effect on the signal level in the node, the source of the noise is isolated in the node immediately preceding the node under test.
