Abstract: A method for fueling an automotive vehicle 26 on a conveyer line 28 is provided. The conveyer line 28 moves generally along a first axis 170 and the method utilizes a robotic arm 34 with an end effector 54 for fueling a fuel stem 90 of the vehicle 26. The method includes determining a first position of the fuel stem 90 along the first axis 170. The method further includes moving the robotic arm 34 to position the end effector 54 proximate to the first position. The method further includes determining a three-dimensional position of the fuel stem 90 utilizing a vision system 164. The method further includes moving the end effector 54 proximate to the three-dimensional position to enable the end effector 54 to mate with the fuel stem 90 and moving said robotic arm 34 relative to said first axis 170 at a speed substantially equal to a speed of said conveyer line 28. Finally, the method includes fueling the fuel stem 90 with the end effector 54.

Abstract: A laser diode (22) emits laser light which is collimated into parallel rays with a collimating lens (24). The collimated beams travel about 5 to 50 cm before being reflected back to an adjustable mirror (28), to a fixed mirror (30), and then on to a photoreceiver (34). The adjustable mirror (28) is pivoted by turning an adjusting screw (40). The adjustable mirror (28) has a toothed cam (48) on its backside that mate with the threads of the adjusting screw (40). When the adjusting screw (40) is turned, it forces the cam to move with it, thus changing the angle of the adjustable mirror (28). A ball lens (32) focuses the reflected light onto the photoreceiver (34). The photoreceiver (34) and laser diode (22) are synchronized so that the receiver (34) can only receive light during appropriate windows of time corresponding to when the laser light was emitted.

Abstract: A method for refrigeration system control according to the invention includes identifying a lead circuit having a lowest temperature set point from a plurality of circuits, wherein each circuit includes at least one refrigeration case. The suction pressure set point for a compressor rack is initialized based upon the identified lead circuit, and a change in suction pressure set point is determined based on measured parameters from the lead circuit. The suction pressure set point is updated based upon the change in suction pressure set point. A first valve position for a first electronic evaporator pressure regulator associated with a first refrigeration circuit is determined based on the determined change in suction pressure set point, which is based upon the measured parameters from the lead circuit. A second valve position for a second electronic evaporation pressure regulator associated with a second refrigeration circuit is based upon a second measured parameter.

Abstract: A system for supplying air to first and second regions of a vehicle passenger compartment, has a first fan, a heater device, and first and second air conduits. The heater device has a first air inlet and outlet for air from the first fan and a second air inlet and outlet for recirculating air within the passenger compartment. The first and second outlets of the heater device supply air through the first and second air conduits to the first and second regions of the said vehicle. The second air conduit is connected to said second air outlet of said heater device via a second fan operable in use to selectively supply air through the second conduit to the second region of the vehicle.

Abstract: A backlit display apparatus illuminates a film for displaying one or more images. The film has a series of frames and at least one mark printed on it corresponding to each frame. The marks provide information representative of frame position relative to the film or otherwise identifying the image displayed by the frame when illuminated. A light source, positioned behind the film relative to an intended viewer in front of the film, illuminates the frames. A detector detects the marks printed on the film as the film is advanced by a motor. An encoder associated with the motor detects the position of the frames as a function of the angular position of the motor when each mark on the film is detected. In response, the encoder generates a position signal representative of the detected positions of the frames. A processor controls the motor in response to the position signal to advance the film so that a selected frame is within the desired viewing area for a predetermined interval of time.

Abstract: A mechanism used for locking a valve that provides positive control of the valve lock to prevent the valve from changing position unintentionally. The positive locking valve control device preferably comprises a push-pull rod having a toothed configuration that is engaged at different positions by a spring mechanism on the valve locking device in order to hold the push-pull rod and thereby the valve securely in place. To adjust the opening of the valve, the push-pull rod can be rotated by some predefined amount (such as 90 degrees) clockwise or counter-clockwise. This rotation frees the locking spring on the valve locking device from the teeth aligning it with a side of the push-pull rod thereby permitting linear movement of the rod to cause a corresponding adjustment in valve position. The rod is then “pushed in” or “pulled out” to adjust the size of the valve opening until the desired flow through the valve is obtained.

Abstract: A hinge construction for pivotably connecting a pair of members together, such as for connecting the access cover of a power inlet box used in connecting an auxiliary generator to the electrical system of a building. The construction includes a mounting member including a knuckle fixed to the power inlet box. An access member includes a pair of spaced apart, pivot lugs disposed one on each side of the knuckle for movement between a closed position in which the access cover engages the mounting member to prevent access to the power inlet box, and an open position for providing access to the power inlet box. A hinge pin passes through aligned apertures in the mounting member knuckle and the access cover lugs, and forms a rotational axis about which the access cover pivots. A torsion spring surrounds the hinge pin and has a first end retained in the mounting member knuckle and a second end disposed outside the access cover lugs.

Abstract: A fluid cutting tool and method for perforating or severing tubular members from inside. The tool is especially suited for use with a rotational drive system, such as a downhole motor, to separate downhole structures, such as stuck production tubing. The cutting tool preferably takes the form of an elongate metal body with an open first end connectable to the end of a downhole motor. The downhole end of the tool may be conical. A fluid conduit within the body of the tool communicates with the fluid channel in the downhole motor. Ports in the sides of the tool body direct jets of cutting fluid out the side of the tool. The tool attached to the motor is fed downhole until the tool is at the desired location in the well. Then the motor is operated to rotate the tool while cutting fluid is pumped through it. This causes the jets of fluid to be directed at the inner surface of the production tubing (or other tubular structure). This process is continued until the tubing is perforated or severed, as needed.

Abstract: A process for cooking food products, such as battered and breaded pieces of meat, with hot oil by placing the products on a conveyor and passing them through a plurality of descending hot oil curtains to enrobe and cook the products. The cooking oil is supplied from above through oil inlet weirs in a smooth curtain with the flow volume and temperature being controlled. The cooking oil is returned for reheating and the products are removed from the conveyor in a cooked condition.

Abstract: The combination of an article to be monitored and a security system. The article to be monitored has a first component and a second component projecting angularly from the first component. The security system has a base and a cover movable guidingly relative to the base between first and second positions. The cover has a first opening through which the second component projects. The cover defines a receptacle for the first component with the second component projecting through the first opening. The cover has an entry opening which allows a) the second component to be selectively projected through and withdrawn from the first opening and b) the first component to be selectively placed in and removed from the receptacle with the cover in the first position. The base and cover cooperatively prevent c) the second component from being withdrawn from the first opening and d) the first component from being removed from the receptacle with the cover in the second position.
