Abstract: APPARATUS FOR RELIEVING BLOCKAGE OF   THE PULP DISCHARGE PASSAGE IN A    CYCLONE IN A PULPING SYSTEM                ABSTRACT OF THE DISCLOSURE Apparatus for relieving blockage of the pulp discharge passage in a cyclone separator included in a pulping system. The pulp stock is treated in an environment of superatmospheric steam and discharged together with the steam into the separator cyclone.  The separated processing steam is evacuated from the cyclone while the steam liberated pulp stock is propelled through a throat which tapers towards the discharge valve by a screw con-veyor whose flights are contoured to rotate snugly within the tapered throat.  The discharge valve is controlled to maintain a predetermined rate of discharge and a predetermined superatmos-pheric pressure within the cyclone to allow evacuation of steam therefrom.  The shaft of the screw conveyor is reciprocally mounted in the cyclone to allow the screw flights to yield in re-sponse to a predetermined excessive thrust resulting from com-pacted pulp stock blocking the throat, to provide a by-pass be-tween the screw flights and the throat wall and thereby relieve the blockage.  The invention may also include sensor means for controlling the rate of discharge in response to variations in thrust on the compacted pulp stock by the screw conveyor.

Abstract: TRANSIENT VOLTAGE SURGE SUPPRESSING DEVICE                 ABSTRACT OF THE DISCLOSURE           A device for suppressing transient voltage surges is mountable at the end of a branch circuit in place of a conventional duplex receptacle.  When so mounted, the device in external configuration duplicates the duplex receptacle exactly, except for omission of one of the two sets of slots normally provided for receiving the prongs of attachment plugs.  The device, when mounted in a conventional outlet box, receives a conventional duplex receptacle wall plate, and being of the external configuration matching that of a conventional duplex receptacle, provides no projection beyond the wall plate greater than the projection defined by the raised portions of an ordinary duplex receptacle as heretofore known.  Use of completely conventional duplex receptacle components, modified either not at all or only slightly, is permitted.  The cover of the device is modified only to the extent of omitting the prong receiving slots at one end, and providing an internal recess for engaging the suppressor element and holding the same in proper position within the body of the device.  The body of the device is modified only to the extent of providing a continuous, transverse suppressor element compartment at one end instead of tile separate compartments normally provided of the receptacle contacts.  Receptacle contact strips are utilized, modified only in that at one end thereof, two of the contact leaves normally provided are omitted, and the remaining leaf is adapted to constitute a wire lead terminal to which is connectable the ends of the suppressor element.

Abstract: ABSTRACT OF THE DISCLOSURE   Equipment for ultrasonic testing structural materials includes transducers and test electronics normally operated in sequential test cycles each cycle including the generation of a test pulse to be set into the test object and subsequently upon interaction with the test object, return signals (echos) are received and processed, e.g. as to transit time, amplitude, contour, etc.  Self-checking is carried out in three phases.  One phase uses simulated receiver signals for operatively disconnected transducers, to be processed by the electronics as if they were echos;  a second phase uses simulated transducer inputs and analogous processing and a third phase uses a reference body as test body simulation for conduction of "tests".        The results of signal processing are compared with reference signals and correlation of deviations and absence of deviations is used to isolate malfunctions.

Abstract: TELEPHONE LINE CIRCUIT Abstract of the Disclosure A telephone line circuit for supplying energizing current to a telephone line and for providing a voice frequency connection between the telephone line and an associated switching facility includes a transformer having a split primary winding consisting of n turns for connection across the telephone line and for connection to a power supply or battery.  A first current flows in the split primary winding in proportion to the telephone line load characteristic.  A balance winding in the transformer is connected in series with one portion of the split primary winding. The balance winding is counter-wound relative to the split primary winding and consists of more than n turns.  A circuit including a current regulator causes sufficient balance current to flow in the balance winding to substantially cancel the d-c flux associated with direct current in the split primary winding.  The first and balance currents additively combine to produce the energizing current for the telephone line, whereby the load on the power supply is  no greater than that of a conventional line circuit in spite of the balance current requirement.                             - i -

Abstract: SEGREGATING USED CATALYST FRACTIONS       BY LIQUID FLUIDIZATION             ABSTRACT OF THE DISCLOSURE Used catalysts contaminated with various metals contents during processing of hydrocarbon feedstocks can be effectively segregated by density difference using fluidization with a light liquid having selected specific gravity range.  The lighter weight less contaminated catalyst portion which rises is returned to the reaction zone for further use, while the heavier more contaminated catalyst portion which drops is usually discarded.  Such segregation recovery and reuse of still active catalyst particles from a reaction process significantly reduces the overall catalyst consumption and costs for various catalytic reaction processes.  This catalyst segregation and reclaiming procedure is particularly useful for recovering used catalyst from fluidized catalyst be systems, e.g. H-Oil? and H-Coal? hydrogenation processes using ?bullated bed reactors, from fluid catalytic cracking (FCC) processes, and also from fixed catalytic bed reaction systems.

Abstract: III. Abstract:      There is disclosed a new and improved hair treat-ment device which comprises a fan for blowing air out of the device against a person's hair, a heater for heating the air before it is blown out of the device, and a means to control the airflow velocity which means is located at the forward end of the conduit for the heated air.  Specifically, the airflow velocity control means is a pair of hinged trap doors disposed within the air conduit which are adjustable with in-finite variability between the maximum opening capa-bility of the air outlet in the hair treatment device and the minimum opening.  The preferred means for adjusting the opening between the trap doors is a knob disposed on the outside of the air conduit portion of the device which is in operative relationship with a screw in operative relationship with the trap doors. The screw has two oppositely threaded portions, one portion having a right-hand thread and the other portion having a left-hand thread and is inserted in both the trap doors each of which have an opening containing female threads adapted to engage a threaded portion of the adjustment screw.  One trap door engages the left-hand thread and the other trap door engages the right-hand thread so that as the screw is turned by the knob, the trap doors rotate in opposite directions about their respective hinges.  In oper-ation, the user adjusts the opening by turning the knob while drying, shaping or styling the hair in order to obtain the desired airflow velocity and to obtain either a concentrated, dispersed or inter-mediate airflow.
