Abstract: ABSTRACT           A gate for controllably inhibiting passage through a controlled zone which includes a rotating arm, the rotation of which may be prevented by a solenoid-coupled pawl which engages a gear-like multiposition detent member coupled to a shaft on which the arm is mounted.  In the event excessive force is applied to the arm when thus locked to enable emergency egress, a clutch allows rotation of the shaft, and of the arm, with respect to the detent member.  The arm may be automatically repositioned to enable a new position about the periphery of the detent member to become engageable by the pawl.

Abstract: SEPARATELY REMOVABLE TUBES IN HEAVY   DUTY HEAT EXCHANGER ASSEMBLIES                Abstract of the Disclosure The invention is directed to removable heat exchanger tube assemblies in heavy duty equipment radiators in which the tubes are each separately removable if they become defective in service.  An inwardly facing annular ledge or abutment is molded into the inside diameter of each upper and lower sealing member to receive the respective ends of the tubes and prevent vertical movement of the tubes in service.  A flange or shoulder is also provided on the lower portions of each tube and engages the inside of the lower sealing member to further restrain downward movement of the tubes in service.  Each tube may be removed by pushing the tube upwardly to overcome the upper ledge abutment and thereby lift the tube free of the lower seal.  Each tube may then be removed sidewise from the radiator.  Variations of the removable sealing arrangement can be made and are described herein.

Title: Control panel for automatic transfer switch
Inventor: PRZYWOZNY WALTER C

Granted: 1981-12-15
Abstract: CONTROL PANEL FOR AUTOMATIC TRANSFER SWITCH      Abstract of the Disclosure A control panel, formed entirely of solid state compon-ents, for an automatic transfer switch which alternatively connects a load to a normal source of power or starts up an emergency source of power and connects the load to it.  The control panel includes a voltage monitor for the normal source, the monitor having a pickup voltage and a lower dropout voltage, a relay for initiating operation of the emergency source when the normal source drops below the dropout level, and a time delay circuit between the monitor and the relay preventing operation of the relay if the voltage drop lasts for less than the time delay provided.  A feedback loop between the time delay circuit and the monitor causes the monitor to respond to normal source voltage above the pickup level for the duration of the time delay.  The monitor continuously monitors all three phases of a three phase normal source.  A monitor for the emergency source independently monitors the voltage and fre-quency of the emergency source.  The emergency source voltage and frequency monitors have a pickup level and a lower dropout level.  A relay causes operation of the transfer switch when the emergency source voltage and frequency rise above the pickup level, and a time delay circuit between the relay and voltage monitor prevents operation of the relay for a pre-determined period after the emergency source voltage rises above the pickup level.  A feedback loop causes resetting of the time delay circuit each time the emergency source voltage drops below the pickup level.  The relay responsive to the normal source monitor has a pair of contacts in a circuit for starting and maintaining the emergency source, and auxiliary contacts controlled by the transfer switch are in parallel with the relay contacts to keep the emergency source operative should the transfer switch fail to shift the load from the emergency source to the normal source.  A relay responsive to the normal source monitor has four pairs of contacts for operating the transfer switch.  Four pairs of auxiliary con-tacts controlled by the transfer switch are located respectively between each pair of relay contacts and the two power sources so as to separate the relay contacts from the power source.                    *              *               *

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus for the pulping of waste material is dis-closed including a tank, an impeller, a slurry chamber, and a discharge pipe for removal of slurry from the chamber.  A flow directing device is provided within the chamber for increasing the flow into the discharge pipe.  The device is appropriately positioned and shaped so that it will deflect the slurry from its rotational flow in the chamber to the discharge pipe.  If the impeller is positioned horizontally at the bottom of the tank, it is preferably positioned off-center so waste material will not directly impinge upon the cutting surfaces when added to the tank.  If the impeller is vertically oriented, the tank may be mounted on shock absorbers or resilient legs to minimize vibration.
