Title: Controlled release potassium divalent metal phosphate fertilizer
Inventor: MOORE WILLIAM P
IPC: C05B17/00
Filed: 1994-05-19
Abstract: A controlled slow release potassium divalent metal phosphate composition for agriculture and an effective method of preparing the compositions. The cold water insolubilities of each of the contained nutrients are between 35 and 98 percent. The potassium exhibits an Activity Index between 20 and 85. The release of all contained nutrients is substantially complete in one growing season without damage to plant foliage or roots. Divalent metals effectively forming the new composition include magnesium, manganese, zinc, iron, cobalt, and copper. The effective method of preparing the new compositions requires the exothermic coreaction of concentrated potassium hydroxide, divalent metal oxide powder, and concentrated phosphoric acid, with a molecular ratio of 1 potassium/1 divalent metal/1 phosphate with the total water content of the initial reaction mixture between 20 and 50 percent, at maximum temperature between 85 and 150 °C, until damp dry, particulate, water insoluble potassium divalent metal phosphate is formed.

Abstract: A remote mains meter reading system comprises a mains system (10, 11, 13, 14), a central station (LC), and a plurality of meters (UI-UII) communicating with the central station by means of messages passed over the mains system. All of the meters act also as message forwarding (relay) units, but knowledge of the topology of the system (i.e. which meters can communicate with which) is known only to the central station. All messages are sent out by, and return to, the central station, the message format includes a list of meters through which the message is to pass. The central station can send out a variety of enquiry (SEARCH) messages to determine the system topology, assign labels to meters, etc. If the mains system includes link boxes coupling different areas together, these boxes preferably filter out messages and includes link units which controllably couple the different areas together.

Title: Apparatus and method for processing a high definition video signal
Inventor: KORI TERUHIKO
IPC: H04N5/913
Filed: 1996-03-18
Abstract: Digital video tape recorder which reproduces from a record medium a digital high definition video signal having copy-prevention data therein, extracts the copy-prevention data from the reproduced signal, generates from the extracted digital copy-prevention data an analog copy-inhibit signal that has the same data format as a copy-inhibit signal superimposed on a standard definition video signal, converts the reproduced digital high definition video signal to an analog signal, and superimposes the analog copy-inhibit signal onto the analog signal for output. To record a high definition video signal, the digital video tape recorder receives an analog high definition video signal that has superimposed thereon a copy-inhibit signal having the same data format as a copy-inhibit signal superimposed on a standard definition video signal, extracts the copy-inhibit signal from the received analog high definition video signal, supplies the received analog high definition video signal when that signal is not copy-protected, converts the supplied video signal to a digital signal, generates digital copy-prevention data from the extracted copy-inhibit signal, adds the digital copy-prevention data to the digital signal, and records on a record medium the digital signal with the digital copy-prevention data added thereto.

The polyethylene resin film exerts the above-mentioned effects.
Patent CA-2173588-A1 (CA)
Title: Storage tank leak detection
Inventor: DENBY CARL
IPC: F02B3/06
Filed: 1994-10-07
Abstract: A method of testing the leakage rates from tanks for containing volatile liquids such as petrol or diesel, with a view to determining whether the tank leaks excessively. The tank is at least partially filled during testing in order to save time. The leakage is detected by sealing the tank and measuring the drop in pressure in the tank over a period of time. In order to measure the rate of leakage, a first measurement is taken during which an amount of 380 ml is removed from the tank over a short period whilst otherwise sealed, with the resultant pressure drop being measured as a calibrated value. The tank is then re-sealed and the pressure drop over the period of an hour is compared with the calibrated value.

Title: Embedded Duplex Local Control Panel
Inventor: GREER DAVID A
IPC: E05F15/00
Filed: 1996-05-01
Abstract: A system for controlling the operation of a door comprising a first microprocessor and a second microprocessor each having a plurality of inputs for sensing the status of a vehicle.  The plurality of inputs include a no motion trainline input, an open trainline input, an unlock trainline input and a close trainline input.   The first microprocessor also has a close grant input for receiving a close grant signal from the second microprocessor while the second microprocessor also has a close request input for receiving a close request signal from the first microprocessor.   The system also includes a motor for opening and closing the door and a motor relay circuit device, controlled  by  the microprocessors,  for  controlling  the direction of power flow through the motor.   When the motor relay circuit device activates, the motor is enabled to open the door and when it deactivates the motor is enabled to close the door.  The system further includes a motor chopper control for controlling the delivery of power to the motor.  The motor chopper control is controlled by the microprocessors so that when the motor relay circuit device  activates,  the motor chopper control delivers power to the motor to open the door and when it deactivates the motor chopper control delivers power to the motor to close the door.  If at least one of the microprocessors detects a system malfunction, the motor chopper control will be disabled thereby preventing power flow to the motor and operation of the door.

Title: Combination water heating and space heating apparatus
Inventor: ARMIJO DAVID L
IPC: F24D19/10
Filed: 1995-08-23
Abstract: A combination water heating and space heating apparatus includes a water heating unit (12) and a space heating unit (14) releasably coupled with the water heating unit. The water heating unit (12) has a water storage tank (20) and a helically wound tubular heat exchanger (82) inside the tank for exhausting products of combustion from a combustion chamber (42) located in a top part of the tank and for transferring heat form the products of combustion to the surrounding water. The space heating unit is an air handler with an hydronic heat exchanger coil (22) and a blower (25) for blowing air over the coil. Hot water is supplied from the tank (20) to the coil and is returned to the tank by means of a water circulation pump (24) located in the space heating unit. Air blown over the coil is heated by the hot water flowing over the coil. The water heating unit and the space heating unit are coordinately controlled such that priority is given to the potable hot water supply over space heating in the event that sufficient hot water is not available to satisfy both demands. Further, the water heating unit anticipates the additional demand for hot water in response to a demand for space heating by raising the tank temperature setpoint so that the water heating operation is usually initiated, even if the temperature of the water in the tank was already at the original tank temperature setpoint when the demand for space heating occurred.
