Title: Method of purifying sewage
Inventor: GILLBERG LARS
IPC: C02F1/52
Filed: 1999-11-05
Abstract: A method of purifying sewage is described. The method relates to purifying sewage in sewage systems which comprise a toilet (1) by adding a precipitant  for precipitation of phosphates and for binding organic substance. The metho d is characterised in that the precipitant is selected from the group consisti ng of iron salts and aluminium salts, such as sulphates, chlorides and nitrates  and is adapted to be flushed with water in the bowl (3) when flushing. In th e method, the sewage from the toilet (1) is preferably conducted to a sludge separator through an outlet pipe (5, 8) which leads to the lower part of the  sludge separator (6) below its outlet (7).

Inventor: JOHNSON HUGH E
IPC: F25D1/00
Filed: 2001-07-16
Abstract: A conduit running from a freezer or refrigerator to the outside air with a fixture at each end, uses cold outside air to keep a refrigerator or freezer cool, with less dependency on energy usage. Cold air from the outside is allowed to enter the pipe through the fixture and because cold air drops and the pipe its self slopes downward, the cold air continues through the pipe, through the inside fixture, and into the freezer. The temperature outside has to be as low or lower than the desired refrigerator temperature in order for it to be effective.

Patent CA-2361216-A1 (CA)
Inventor: BENJEY ROBERT PHILIP
IPC: B60K15/077
Filed: 2001-11-07
Abstract: An improved fuel level responsive peelaway action valve for vehicle fuel tanks, in which a float moves a valve closure element into sealing contact with a vapor venting outlet, and then pulls or "peels" the valve element off the vapor venting outlet when fuel level drops. The valve closure element comprises a thin, flexible sealing portion for engaging the vapor venting outlet with low sealing forces, and a stiffened marginal portion acted on by a rigid cage or frame which is connected to the float. As the float drops, the cage contacts the stiffened marginal portion and levers the valve element off the venting outlet.

Inventor: HANSEN DOUGLAS P
IPC: G02F1/13
Filed: 2000-07-27
Abstract: An image projection system having a wire grid polarizing beam splitter (4) which functions as both the polarizer and the analyzer in the system. A light source (20) produces a light beam directed at the beam splitter (14) which reflects one polarization and transmits the other. A liquid crystal array (26) is disposed in either the reflected or transmitted beam. The array modulates the polarization of the beam, encoding image information thereon, and directs the modulated beam back to the beam splitter. The beam splitter again reflects one polarization and transmits the other so that the encoded image is either reflected or transmitted to a screen (25). The wire grid polarizing beam splitter is capable of being oriented at various angles with respect to the source light beam and modulated beam, and accepts relatively divergent light.

Title: A system for working at a remote office pbx
Inventor: KAPLAN ALAN E
IPC: H04M11/06
Filed: 2002-05-29
Abstract: An arrangement that includes at least two PBXs interconnected by a network employs CTI ports to control operation of the PBXs. Through such control, a user can set up a telephonic presence in a visited PBX such that, to the user and to all others who interact with the user, it appears that the user is at the user's office, rather than at an office that is served by the visited PBX. This is effected by forwarding calls that are destined to the user at the user's office to the visited PBX, and by translating all dialing commands of the user at the visited PBX, and acting upon the translated commands, so as to provide the user with the features available to the user at the user's office while presenting an appearance to called parties that the user is at the user's office.

Filed: 2000-05-26
Abstract: A vapor compression system (10) including an evaporator (16), a compressor (12), and a condenser (14) interconnected in a closed-loop system. In one embodiment, a multifunctional valve (18) is configured to receive a liquefied heat transfer fluid from the condenser (14) and a hot vapor from the compressor (12). A  saturated vapor line (28) connects the outlet of the evaporator (16) and is sized so as to substantially convert the heat transfer fluid exiting the multifunctional valve (18) into a saturated vapor prior to delivery to the evaporator (16). The multifunctional valve (18) regulates the flow of heat transfer fluid by monitoring the temperature of the heat transfer fluid returning to the compressor (12) through a suction line (30) coupling the evaporator (16) outlet to the compressor (12) inlet. In one preferred embodiment, a bifurcated liquid line connects the condenser (14) outlet to the first inlet of an multifunctional valve and the inlet of a metering unit.

Title: Combined oil return and compressor discharge temperature limitation regarding flooded economizer heat exchanger
Inventor: FREUND PETER W
IPC: F25B43/00
Filed: 1995-01-13
Abstract: A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compres-sor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respec-tively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchang-er. The valves are controlled in at least one predeter-mined open/close pattern during a null cycle, and prefera-bly in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which sub-stantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null tempera-ture range close to set paint, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein.      The system achieves the latter by controlling cooling circulation in the compressor oil cooler.
