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 compressor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respectively: (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 exchanger. The valves are controlled in at least one predetermined open/close pattern during a null cycle, and preferably in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which substantially 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 temperature range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein.

Abstract: When the driver parks a truck for the purpose of sleeping in the cab's bunk space and desires to have the air conditioner operate, fan clutch cycling, which may create objectionable noise that disturbs sleep, is avoided by the inclusion of a branch circuit off of the air conditioner switch that comprises a parking brake switch in series with a relay coil. When the air conditioner is on and the parking brakes are set, this relay coil is energized to open a circuit to the engine fan clutch solenoid, preventing the fan clutch from being disengaged, and thereby keeping the fan in driven relation to the engine crankshaft so that fan clutch cycling does not occur.

A lead bar is coupled to upper die plate at one end and a hydraulic chuck at its other end and includes helical grooves on its surface that mate with helical protrusions on lead nuts.

Abstract: An annular member is placed on a forming profile of a convex die without fixing the annular member to the convex die. Then, the convex die is moved toward a concave die which has an axis inclining with respect to an axis of the convex die. When the convex die is moved toward the concave die, the concave die is revolved around the axis of the convex die. The concave die does not revolve about its own axis. Revolving the concave die around the axis of the convex die may be replaced by forcibly rotating the convex die about its own axis. When a compression load is imposed on the annular member, opposed ends of the annular member are formed simultaneously.

Abstract: A flanging apparatus includes a flanging head assembly having a cluster of freely rotatable spin flanging rollers and a stop ring against which the flange hits during the final flange forming stages to limit the flange to a specific diameter. To prevent the flange from entering the crack formed between the rotating roller and the stationary stop ring, there is provided a step spacing the stop ring surface from the roller forming surface. The forming process occurs as a result of spring biased relative axial movement of the can open end toward the forming surfaces, caused by contact between the can bottom with a base pad movable in a working stroke toward the flanging rollers with a cam controlled spindle. A spring extends between the base pad and a base pad spring collar attached to the spindle to create a predetermined spring force which is normally applied throughout the flange forming process.

Abstract: For mapping and exploring bodies of water, fan depth finders are used that emit ultrasound pulses and receive-echo pulses in a number of tightly-bundled receiving sectors. Because the predominant number of receiving directions is oriented diagonally downward instead of straight down, these ultrasound pulses propagate on bent paths due to sound refraction. Sound refraction is caused by different sound velocity layers, the precise knowledge of which is necessary for determining an average sound velocity. The method of the present invention does not require a separate measuring probe to measure the sound velocity at different depths; rather, the average sound velocity is determined using a regression method based on the travel time measurements of the ultrasound pulses. In this method, first the floor profile that forms the basis of the measured travel times is determined with an assumed average sound velocity and compared with a floor profile model composed of partial functions modeled in a specific manner.

Abstract: A variable length crank arm in a windshield wiper system provides a depressed park position for an associated wiper blade when the direction of rotation of a drive motor is reversed. The crank arm relies on an eccentric driver to vary its length between a first length and a longer second length. When the eccentric driver is rotated in a first direction to wipe the windshield, a spring loaded pin keeps the eccentric driver rotatably fixed to an output arm with the crank arm consequently at the first length. The spring loaded pin also engages a cam slot in a cam plate, the cam plate rotating freely with the output arm and the eccentric driver in the first direction. To move the blade to the depressed park position, the direction of rotation of the drive motor is reversed. This causes the cam plate to become rotatably stopped, with the now stationary cam slot forcing the pin out of engagement with the output arm.
