Patent number: 4552061Abstract: A trash compactor system which includes a trash compactor unit, a compaction receptacle and a trash deposit door disposed above the receptacle to enable trash to be desposited in the system. The door is automatically opened when a person approaches the compactor to deposit waste material therein by pressure being applied to a mat switch positioned on the floor adjacent the compactor. The compactor member compacts waste in the receptacle by passing through a compaction cycle. When pressure is removed from the switch, a predetermined time period has elapsed and the waste deposit door is closed, the compaction cycle is initiated. At this time, mechanical locks within the compactor are forced against the door, preventing the door from being opened during the compaction cycle. The mechanical locks are released after the compaction cycle is completed.Type: GrantFiled: October 3, 1983Date of Patent: November 12, 1985Assignee: AMF IncorporatedInventor: James W. Brutsman

Patent number: 4550605Abstract: The invention relates to nondestructive inspection apparatus for automatically inspecting the end region of a tubular member and a coupling member secured to that end region. An inspection probe is yieldingly received within a housing that is pivotally supported on an arm that moves helically around the tubular member. The probe is extended outwardly from an air chamber in the housing to contact the surface of the tubular member. When the probe encounters the obstructing shoulder of the coupling on the end of the tubular member, the housing is caused to pivot to activate an air escape mechanism to reduce the air pressure in the chamber and cause the probe to be withdrawn radially to hop over the obstructing shoulder on the coupling. The housing then returns to its original position to terminate the air escape from the chamber. Air pressure builds up again to force the probe outwardly onto the surface of the coupling.Type: GrantFiled: August 15, 1984Date of Patent: November 5, 1985Assignee: AMF Inc.Inventor: Elizabeth M. Bains

Patent number: 4527261Abstract: The invention is a method and apparatus for substantially eliminating from a seismic signal channel an interfering hiline signal in a differential mode. Differential mode and common mode components of the interfering signal are coupled from the seismic signal channel, and are correlated with each other to obtain a correlation signal. The correlation signal and the common mode signal are multiplied to obtain a correction signal that is applied to the seismic signal channel to substantially eliminate the differential mode component of the hiline interference signal. The correlation between the differential mode and common mode signals is accomplished with both in-phase and quadrature phase components of one of them so that two correlation signals actually are produced.Type: GrantFiled: October 7, 1981Date of Patent: July 2, 1985Assignee: AMF IncorporatedInventor: Miles A.

Patent number: 4268884Abstract: A current sensing circuit that controls a contactor that connects a load to power lines. The circuit provides an initial momentary delay period after energization of the circuit and before operation of the contactor to permit transients and other short duration anomalies to die out. An immediately succeeding second momentary delay period during which the contactor operation cannot be changed, assures that an initial inrush of current to the load will not cause a fault signal to erroneously operate the contactor. When a fault signal does cause the contactor to be operated, the circuit cannot be set back to its intended operation condition until energization of the sensing circuit is manually interrupted and reestablished. During normal operation of the circuit when current on the power lines is within acceptable limits, the circuit is latched in its proper operating mode.Type: GrantFiled: May 7, 1979Date of Patent: May 19, 1981Assignee: AMF IncorporatedInventors: John R. Ford, Jr., Harold D. Leipold

Patent number: 4228475Abstract: A ground monitoring circuit for detecting the existence and proper connection of the ground wires in an electrical power cable of a type commonly used at a surface mining site. A complete conductive loop is established between the ground conductor, or conductors, and the ground check, or pilot, wire of the cable. A sensing signal at a frequency higher than the power frequency is coupled onto the ground monitoring loop. The voltage and current in the loop are separately sampled. Various comparisons of the voltage and current samples are made to detect any deviation in the resistance and/or reactance characteristics of the loop. Any deviation from desired conditions in the loop produce one or more output signals that change the condition of a trip relay. The trip relay initiates action that ultimately opens circuit breakers to remove power from the cable.Type: GrantFiled: August 28, 1978Date of Patent: October 14, 1980Assignee: AMF IncorporatedInventor: John R. Sherwood
