Patent number: 4397726Abstract: A cathodically protected storage structure, such as a liquid manure storage tank. The structure comprises a generally cylindrical shell formed of steel plate sections which is mounted on a support or foundation. The steel plate sections are coated with a corrosion resistant material, such as glass, and are bolted together at their overlapping joints. A group of anodes, formed of a metal electropositive to steel, are mounted within the structure, and electrical leads, which are connected to the anodes, pass through bolt holes in the wall of the structure and are connected on the outside of the structure to the metal plate sections. As the anodes are electropositive with respect to the steel plate sections, the anodes will corrode preferentially to thereby protect the steel against corrosion.Type: GrantFiled: October 13, 1981Date of Patent: August 9, 1983Assignee: A. O. Smith Harvestore Products, Inc.Inventor: Joseph A. Schwert

Patent number: 4396083Abstract: A hydraulic steering assistor, which can be switched off, for a vehicle with a hydraulic pump, an electric motor and a relay, which vehicle is driven by an electromotor, runs on wheels and is actuated by means of a drive control. By means of a switch disposed in the drive control, the motor of the hydraulic pump for the steering assistor is turned on through a time relay (having an activatable delay time) and another relay, and during the rotation of the armature shaft of the electromotor of the vehicle the time relay receives pulses from a pulse generator in the electromotor preventing the activation (initiation) and thus expiration of the delay time, and the pump driving motor for the steering assistor is stopped only after the absence of the pulses while in the neutral position, causing activation of the time relay and then after expiration of the delay time, by means of the drive control and opened switch.Type: GrantFiled: July 29, 1980Date of Patent: August 2, 1983Assignee: O&K Orenstein & Koppel AktiengesellschaftInventor: Manfred Wehberg

Patent number: 4390486Abstract: This apparatus is used to improve the heat distribution on the cavity surface in foam molding dies where a smooth finish on the resin filled foam molded plastic product manufactured by an injection molding process is desired. This invention improves the method for heating the mold cavity using a condensing vapor in a molding die by a channel and slit type orifice means in the mold around a portion of the periphery of the part to be molded. Another channel and slit type orifice means around the remaining periphery is included in the die for removing the condensing vapor or condensate from the mold cavity. During the heating process when condensing vapor is introduced into the mold the sprue opening to the extruder is sealed by a valve means to prevent condensate from collecting therein.Type: GrantFiled: March 19, 1981Date of Patent: June 28, 1983Assignee: Ex-Cell-O CorporationInventors: James W. Hendry, Je-Chin Han

Patent number: 4389635Abstract: An attachment which converts a single station, spring powered, temperature sensitive, fire alarm protection device into a remote signalling heat detector for a central fire alarm system, without affecting the internal apparatus of the alarm device or the environmental protection of such internal apparatus. The attachment includes a pivotally mounted member having a shield arm interposed between a magnet and a reed switch, and a lever arm which interacts with a winding key on the alarm device to move the shield arm from between the magnet and reed switch when the alarm is actuated. This movement of the shield arm permits the magnetic force of the magnet to activate the reed switch. The reed switch is connected by wire or radio link to a central monitor. Actuation of the reed switch, in response to actuation of the alarm device, produces an alarm signal at the central monitor.Type: GrantFiled: November 28, 1980Date of Patent: June 21, 1983Assignee: A-T-O, Inc.Inventor: Edward L. Gallagher

Patent number: 4386695Abstract: A sweep arm construction for a bottom unloading mechanism used to unload generally free flowing material from a silo or storage structure. The sweep arm is mounted to rotate about the center of the silo and undercut the stored material and convey it to the center of the silo where it is delivered to a discharge auger that operates in a radially extending trough in the silo foundation. The sweep auger is composed of a series of shaft sections of different diameters with the innermost shaft section having the largest diameter. A helical flight is associated with each shaft section and the flight on each shaft section has a progressively increasing radial depth in a direction toward the inner end of the sweep arm to provide a uniformly increasing rate of delivery to the auger.Type: GrantFiled: November 10, 1980Date of Patent: June 7, 1983Assignee: A.

Patent number: 4386625Abstract: A valve system includes features to control flow of fuel between a pair of fuel tanks during a transfer operation so as to prevent flow of return fuel from a carburetor back to a previously filled tank. The valve system includes a pair of valve bodies each having two mechanically operated sealing elements therein. One of the valve bodies has larger inlet and outlet ports to control the supply of fuel from the source tank of the system to a vehicle carburetor. The other of the valve bodies has smaller ports to control the flow of excess fuel flow to the selected source tank of the pair of tanks during engine operation. Each of the valve bodies includes a push rod operatively connected to a single motor drive yoke element. Each sealing element is spring biased and has an insert directed therethrough constituting a seal carrier slidably supported on the push rod.Type: GrantFiled: May 7, 1981Date of Patent: June 7, 1983Assignee: Ex-Cell-O CorporationInventors: Jimmie G.
