Abstract: COMMON RELUCTANCE PATH MULTI-GAP MAGNETIC TRANSDUCER                    Abstract A magnetic multi-gap transducer having a single integrated core structure with a central common I-bar and a pair of flanking pole pieces.  A first relatively low reluctance magnetic path is formed by the I-bar and a first one of the flanking pole pieces to provide a recording gap having a read function capability.  A second relatively high reluctance magnetic path is formed by the central I-bar and the other flanking pole piece, the low reluctance being provided by a relatively large non-magnetic air gap there between.  The integrated core structure is embedded in a non-magnetic slider, and each flanking pole piece has an electromagnetic coil received there about.

Abstract: METHOD OF AND APPARATUS FOR  REMOVING LIQUID FROM WEBS OF      POROUS MATERIAL           STRONG CHIEU-HSIUNG CHUANG        and HUGH ANSLEY THOMPSON                 ABSTRACT       An apparatus for removing water or other liquids from webs of such porous materials as fibrous paper webs coursing through a papermaking machine without substantially compacting the webs. The web which may be coherent or perforate passes over a sector of a cylinder having preferential-capillary-size pores through its cylindrical-shape porous cover. Preferably, the porous cover comprises hydrophilic material which is substantially non-resilient and which renders the surfaces of the porous cover wettable by the liquid of interest. A portion of the interior of the cylinder may be subjected to a controlled level of vacuum to effect pneumatically augmented capillary flow of liquid from the web; and another portion of the cylinder may be subjected to pneumatic pressure for expelling the transferred liquid outwardly through a portion of the porous cover which is not in contact with the web. The method may comprise controlling the level of vacuum as a function of air flow to maximize liquid removal from a web while substantially obviating air flow through the capillary-size pores of the porous cover of the cylinder. Preferential-capillary-size pores are such that, relative to the pores of a wet porous web, normal capillary flow would preferentially occur from the pores of the web into the preferential-capillary-size pores of the porous cover when the web and porous cover are juxtaposed in surface-to-surface contact.

Abstract: ABSTRACT OF THE DISCLOSURE     STACKER FOR FLAT OBJECTS The invention relates to a stacker for flat objects, in which a conveyor moves the objects to be stacked in in an edgewise manner. A drum rotates permanently in front of the orifice of a hollow cylindrical body, connected to a suction source. The stack of already stacked objects is engaged against said drum. A shell, controlled in rotation by control means, controls the application of suction through the openings of the drum, of an object inserted between the drum and the stack. Suction application is timed to correspond to a displacement of the leading edge of the object inserted between the orifice and the stopping border of the receptacle.

Abstract: DIFFUSER CONSTRUCTION FOR A CENTRIFUGAL COMPRESSOR Abstract of the Disclosure Constant flow width through the last stage diffuser of a centrifugal compressor is maintained against widening by the forces of differential pressure via a diffuser defined between oppositely positioned radial faces of a diaphragm and an annular diffuser plate secured spaced from the diaphragm at the desired with.  Enabling the diffuser plate to withstand width deflection and/or enlargement is a pressure balance imposed against the rear surface of the plate as compared to the pressure level incurred from the gas flow at the front surface facing the diaphragm.  This is achieved by a sealed radial cavity exposed to the rear surface of the plate and in continuous pressure communica-tion with the front surface through a plurality of vent holes extending therebetween.

Abstract: Application Of: Dettertburn N. Rohemus and Victor M. Tice For:   Plug-In Ground Fault Circuit Interrupter Module Abstract Of The Disclosure Ground fault circuit interrupter means are enclosed within a housing having terminals for connection of the wires of a line cord extending from an electrical appliance or other electrical load for which ground fault protection is provided. Standard plug blades extend from the housing for insertion into a conventional electri-cal receptacle to connect the load to a source of electrical power, the circuit interrupter means being interposed between the wire connection terminals and the blades. The housing configuration and assembly provides an essentially waterproof enclosure for all elements between the line cord and plug blades which is preferably divided into two discrete compartments, one containing the wire connection terminals and the other the GFCI components. Thus, if the one compartment should develop a leak, the water tight integrity of the other is still maintained. The line cord extends into the module through a resilient sealing grommet which may conveniently be interchanged with different size grommets to accommodate line cords of various diameters without changing any other components of the module. Assembly is simplified and facilitated by providing a one-piece body member, open at both ends, and connecting all other components as a single assembly for insertion into the body and fastening with screws at each end to sealably close the body openings.

Abstract: TITLE SECRETARIAL TELEPHONE STATION WITH DISTRIBUTED      PROCESSING FOR USE WITH A SECRETARIAL           ANSWERING SYSTEM ABSTRACT OF THE DISCLOSURE A secretarial telephone station for use with a secretarial answering system and a switching system which includes a plurality of subscriber telephone stations each equipped with a buzzer.  The secretarial answering system is connected to the subscriber sta-tions and transmits subscriber station busy, idle and ringing status and line identification information to the secretarial station.  The secretarial station includes a lamp and switch pair for each associated subscriber station, first and second processing units, and an audible signalling circuit.  The first proc-essing unit receives this information according to a link bus protocol for packetized messages.  The second processing unit receives this information and causes the lamp associated with each of the subscriber sta-tions to display dark, lit or flashing signals cor-responding to the idle, busy and ringing status.  The second processing unit also causes the audible signal-ling circuit to provide a ringing tone whenever a lamp is flashed.  In response to operation of the switch associated with a called subscriber station, the second processing unit transmits a directed call pickup and a call transfer message to the switching system which route the subscriber's incoming call to the secretarial station for screening.  A buzzing requested message is then transmitted to the secretarial answering system via the first processing unit according to a link bus protocol for packetized messages.  The buzzing re-quested message informs the secretarial answering system to cause the subscriber station's buzzer to provide an audible signal indicating that the current incoming call has been screened by a secretary.
