Abstract: Abstract of the Disclosure Control system for an electronically commutated motor includes circuitry for integrating the back emf of an unenergized motor winding to determine motor rotor position. However, integration should not occur on a field collapse voltage which precedes the back emf.  A zero-approaching detector enables the integration of the back emf only when a zero-approach occurs at the ending of the field collapse voltage.  The integration is also inhibited from being spuri-ously enabled by zero approaches for a predetermined length of time after commutation and prior to the ending of the field collapse voltage.  A system for controlling the average volt-age cyclically applied to a load such as an electronically commutated DC motor includes circuitry for generating a direct function of the applied voltage.  The function is compared to a reference by a comparator which indicates when the function reaches the reference.  The end of each voltage cycle is sig-naled when the function of the applied voltage reaches a pre-determined value.  The external application of voltage to the load is terminated when the function of the applied voltage reaches the reference, and each voltage cycle is terminated when the function of the applied voltage reaches the predeter-mined value.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a proportioning valve which is of simple design compared to prior art arrangements and is easily con-structed.  The valve comprises lower and upper body members, the lower body member having a chamber region closed off by a flexible diaphragm of elastomeric material or, in an alternative arrange-ment, two diaphragms.  The bottom of the chamber region has first and second inlets and the wall of the chamber has at least one outlet.  Two cam followers are secured above the diaphragm, for axial movement only, in alignment with the inlets and they co-operate with a face cam which is movable both axially and rota-tionally.  Rotation of the face cam results in one cam follower moving up, while the other moves down, thus resulting in movement of one portion of the diaphragm towards its associated inlet while the other moves away from its associated inlet, thereby con-trolling the relative rates of flow of liquid into the chamber region from the inlets.  Axial movement of the face cam causes both cam followers to move upwardly or downwardly by the same amount, thus similarly moving the associated portions of the diaphragm and controlling the total rate of flow of liquid into the chamber region.  A handle with a second cam is provided whereby rotation of the handle rotates the face cam while pivoting of the handle results in axial movement of the face cam.

Abstract: ABSTRACT            The invention relates to a snow remover to be used in con-nection with a truck or other suitable vehicle. The appara-tus comprises a snow container which moves on the ground scooping up snow like a snow shovel and is provided with at least one spiral conveyor and a discharge pipe.  The snow gathered in the snow container by the spiral conveyor is let out through the discharge pipe, which pipe is provided with a choker. The spiral conveyor (3) is installed within the snow container (1) in a vertical position so that only its bottom part (31) is attached to the snow container. The spiral conveyor (3) has a conical form and is fitted within a conical sheath (5). The top part of the sheath thus forms the choker (52), which is connected to the bottom part (41) of the discharge pipe. The discharge pipe (4) has a cross-sectional area larger  than that of the  choker  (52).  The discharge pipe (4) is curved, and its radius of curvature (R) is constant. The discharge pipe (4)  is formed of two parts,  i.e.  the bottom part  (41)  and the top part  (42), which are interconnected by means of a hinge-like member (43). In between the two members (41, 42) of the discharge pipe  (4)  there  is  installed  a  hydraulic  cylinder  (44), which is employed to bend down the top part  (42) of the discharge pipe during transportation and storage. Moreover, the discharge pipe (49 is attached to  the snow container (1) with bearings so that it can be turned in the horizon-tal level.            (Fig. 1)

An air-water separator may be disposed between the vortex tube inlet and the heat exchanger for removing any condensed water from the compressed air.  The second compressor receives the cold fraction discharge air and generates a supply of instrument air at a pressure not in excess of 25 p.s.i.g. and which has a dewpoint below the freezing temperature of water.  A method for producing relatively dry, compressed instrument air is also disclosed.

Title: Dual aquafer electrical heating of subsurface hydrocarbons
Inventor: SEGALMAN DANIEL J
IPC: E21B36/04
Filed: 1986-03-19
Granted: 1988-08-30
Abstract: Abstract Electrical current is caused to flow between an electrode well located in an aquafer above viscous hydrocarbon-bearing formation and an electrode well located in an aquafer below the hydrocarbon-bearing formation.  The electrical current thereby tends to spread out in a broad plate-like configuration from each electrode well.  This increases the area of the hydrocarbon-bearing formation through which current is flowed, thereby extending the region which is heated by electrical dissapation.  The nature of the aquafers and their location eases and resolves much of the adverse vaporization and pressure buildup that occurs in other systems.  This also allows water to be readily injected to into or produced from the electrode wells to further control vaporization and pressure buildup without adversely affecting gravity drainage, other drive mechanisms or injection programs operating within the hydrocarbon-bearing formation.  In addition, this enables the electrode wells to be used in a more continuous manner.
