Title: Multiple lateral hydrocarbon recovery system and method
Inventor: MURRAY MARK J
IPC: E21B17/00
Filed: 1996-08-28
Abstract: An assembly for drilling multiple laterals (26) from a borehole and into a formation includes a whipstock assembly having a radially movable lug (82). An elongate tubular secured within the borehole has one or more non-ferrous portions (30) and a ferrous portion (52) adjacent and below a respective non-ferrous portion.

Patent CA-2195028-A1 (CA)
Inventor: MORRIS G GILBERT
IPC: A63C19/10
Filed: 1997-01-14
Abstract: The invention provides a portable ice skating rink including elongate curb structural members and a liner of flat flexible sheet material.  The liner is economically made of sheet plastic for example with a bottom sheet and elongate sleeves around the periphery of the bottom sheet.  The curb members, such as 4x4 lumber pieces, areinserted into an open end of each sleeve to form a water retaining structure.  The sheet material and seams have resistance to water permiation sufficient to retain a shallow pool of water covering the bottom sheet during freezing in outdoor conditions to form an ice skating surface.  Assembly of the rink is minimal.  The user need only lay the liner in the intended location and slide the curb members into the preformed sleeves about the periphery.  The interior depression formed is filled with water and allowed to freeze in outdoor conditions.

Title: Mobile radio transmitting/radio receiving device, in particular the mobile unit of a cordless telephone
Inventor: BIEDERMANN ROLF
IPC: H04B7/005
Filed: 1995-07-19
Abstract: In order to reduce the power consumed by mobile radio transmitting/receiving devices (PT1, PT2) and thus increase their maximum possible duration of operation, the device-specific transmitting power is automatically regulated depending on special information (FSW, A-CRC, X-CRC), such as field intensity values (FSW) and transmission error values (A-CRC, X-CRC), received and acquired by the mobile radio transmitting/receiving device. The mobile radio transmitting/receiving device (PT1, PT2) has for that purpose a sequential control circuit (RK), in which the value of the controlled variables (here the device-specific transmitting power) follows the changing value of the command variable (here the received and acquired special information).

IPC: B60K15/035
Filed: 1996-12-10
Abstract: A vapor recovery fuel system includes a fuel (12) tank having at least one vent opening (24) defined therein. A fuel vapor canister (14) is in communication with the vent opening to receive and filter fuel vapors from the tank. A refueling control valve (22) is configured in the vent opening and has a first inlet orifice (30) and an outlet (34) in communication with the vapor trap. The control valve includes a variably buoyant first float body (36) extending into an interior of the fuel tank which rises over a predetermined range of movement in response to increasing fuel level. The control valve includes a second float body (38) engaged by the first float body over at least a portion of its range of movement. The first float body has a buoyancy during refueling so as to rise with increasing fuel level to engage and move the second float body into a sealing position to seal the inlet orifice (30) from the outlet (34) at a predetermined height (41) of fuel within the tank. The first float body has a buoyancy reducing mechanism (42) for automatically reducing its buoyancy after refueling so that it lowers in the fuel tank thereby allowing the second buoyant body to lower and unseal the inlet orifice after refueling.
Patent CA-2213005-A1 (CA)
Inventor: RENDER DAVID STEPHEN JOHN
IPC: G02B6/44
Filed: 1997-08-14
Abstract: A structure of a printed circuit board and a fiber storage holder for accommodating a superfluous length of fiber to be connected to a terminal on the printed circuit board.  This structure if for use with the board mounted within an electronic shelf and solely accommodates superfluous lengths of fiber with pre-specified lengths. To enable removal of the printed circuit board from its shelf, free fiber is necessary.  This is accommodated by a fiber storage facility which is additional to the holder. The fiber storage facility is located outside the printed circuit board receiving chamber of the shelf and is preferably attached to a shelf wall, e.g. a bottom wall, so as to store a removable length portion of fiber.  Upon removal, the removable length portion provides a free fiber length which, by flexing, allows for removal from and return to the shelf of the printed circuit board.  The fiber may extend between two printed circuit boards mounted in the same or separate shelves with each printed circuit board having its own fiber storage facility.  It is necessary for only one of the printed circuit boards to have a fiber storage holder.

Title: Temperature compensated automatic gain control
Inventor: KORNFELD RICHARD K
IPC: H03G3/30
Filed: 1996-04-22
Abstract: The process and apparatus of the present invention limits the output power of a radio in response to the temperature of key components of the radio.  Temperature sensors (1025) measure the temperature of the components and send the temperature signals to power control circuitry (1030). The transmit power is measured (1020) at the output of the power amplifier (1015). As the temperature increases, the power control circuitry (1030) reduces the transmit power to reduce the temperature of the key components. The power is monitored so that it is not reduced below the power level required by standards.
