Abstract: ABSTRACT OF THE DISCLOSURE:           In order to measure deformations of magnetic material which is being cold-rolled a plurality of magnetoelastic stress-sensing  transducers are used, each of which has two U-shaped magnetic cores provided with windings and  crossing each other perpendicularly.  The cores are mounted with their pole surfaces spaced from the strip being rolled and with the cores  making an angle of 45 % with the longitudinal direc-tion of the strip.  The individual transducers are screened from each other bt a screen of magnetic material positioned axially symmetrically around each transducer, so as to prevent adjacent transducers from magnetically affecting each other except through the field in the measuring object and the leakage field in the air gap between the measuring device and the object.  The transducers are mutually displaceably arranged along a line crosswise of the strip.  Between the transducers and the measuring object there is a protective plate of non-magnetic material with very high resistivity.

Abstract: DUAL FREQUENCY TRACK CIRCUIT            Abstract of the Disclosure There is disclosed a double rail track circuit for use within a railroad block or each cut section of a block.          Adjacent cut sections, or blocks are separated by insulated rail joints.  A transmission line having terminals accessible at each joint is provided.  The transmission line has impressed thereon a modulated carrier signal to provide a reference sig-nal at the modulation frequency.  The reference signal derived from the carrier is coupled to one end of each block, or cut section, in such a manner that the signals of adjacent blocks, or cut sections, are out of phase with respect to each other.  A synchronous detector is coupled between the transmission line and the rails at the other end of the block, or cut section, to compare the phase of the signal at the other end, with the an-ticipated signal phase.  Band-pass filters may be used between the rails and the synchronous detector and between the trans-mission line and the synchronous detector and which do not pass common frequencies.  The system is less subject to interference from inductive coupling from power lines and/or from propulsion currents in the rails than systems employing a reference signal applied directly to a transmission line and coupled to the rails.

Abstract: Application for Patent of CARL T. NELSON      and BRIAN E. HOLLINS      for A MONOLITHIC INTEGRATED CIRCUIT TRANSISTOR   HAVING VERY LOW COLLECTOR RESISTANCE                 ABSTRACT OF THE DISCLOSURE    A monolithic integrated circuit includes a vertical transistor having a low collector resistance with high current handling ability.  The integrated circuit comprises a P type epitaxial layer grown on an N type substrate with both deep and shallow N type diffusions made into the P type layer.  In the high current vertical transistor region with the deep N type diffusion, the deep diffusion penetrates the P layer to the N type substrate, whereas in the other transistor the shallow diffusion does not penetrate to the substrate.  An N epitaxial layer is grown on the P type layer and thereafter normal processing techniques are used to form the base and emitter regions for the devices including the high current transistor which has its collector electrically coupled to the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE        A double glazed window has an appliance comprising a unitary, atmospheric pressure equalization and drying chamber in the form of a sealed, flexible walled container provided with means communicating from its interior to the space between the panes of the window.  A separable coupling between the container and the space permits replacement of the appliance when its dry-ing capability is exhausted.  The window frame construction un-obtrusively incorporates the appliance in a cavity which has a removable cover.  Variations in atmospheric pressure are balanced within the space between the window panes by changes in the at-mospheric pressure on the flexible walled container while such changes transfer gas between the space and the container to ex-pose the space to the desiccant.  One separable coupling passing the gas is a hollow needle inserted through a resilient, self-sealing, passage which can be integral with a seal gasket between the panes.

Abstract: GRAFT POLYMER COMPOSITIONS OF TERMINATED EPOXY RESIN, PROCESSES FOR MAKING AND USING SAME.    AND SUBSTRATES COATED THEREWITH     Abstract Epoxy resin is reacted with a terminating agent to eliminate at least part of the epoxide groups of the resin and form modified resin. The epoxy resin or such modified resin is also reacted with addition polymerizable monomer at elevated temperature in the presence of at least 3% of benzoyl peroxide based on the weight of such monomer. Generally the latter reaction is done at about 110°C to about 120°C. These two reactions can be performed in any desired sequence, or simultaneously. The final reaction mixture produced contains:                 (a) graft polymer;                 (b) ungrafted, modified resin; and (c) ungrafted addition polymer, formed associatively with the graft polymer. While other kinds of grafting can and often do occur between addition polymer and the epoxy resin or modified resin, the term "graft polymer" herein connotes specifically carbon-to-carbon grafting of addition polymer onto the modified resin. The proportion of the graft copolymer in the final reaction mixture is effective for imparting outstanding dispersion stability to aqueous dispersions of the reaction mixture. The modification eliminates vagaries of epoxy reactions. Accordingly, the invention is useful for making coating compositions. The compositions thus can have good weather resistance and are particularly useful for making sanitary coatings for cans for foods and beverages, especially for beer. The coatings compositions can be aqueous dispersions for spray application or concentrates or powders that can be made up readily into aqueous sprayable coating compositions. Organic solvent vehicles also can be used.

Abstract: ABSTRACT OF THE DISCLOSURE            It is possible to provide a dispensing closure which is tamper evident by using a relatively flexible strap connecting the movable end of a spout as conventionally used in such a closure with a cap or cap body employed in such a closure, The use of such a strap makes it possible to mold the spout and the cap as a unitary article. The assembly of a dispensing closure from such an article avoids the possible problem of a "wrong" spout being assembled with a specific cap or cap body.  The strap employed should not extend from the cap so as to interfere with the use of conventional capping apparatus.  The strap used can be shaped and dimensioned to facilitate location of the spout during the assembly of the spout on the cap or cap body and, if desired, as a cover for the passage in the spout when the spout is assembled in an operative position.

Abstract: TITLE OF THE INVENTION           Device for Incorporation in Dental Suction Apparatuses For Separation of Liquid And Solid Components ABSTRACT OF THE DISCLOSURE:     A separator for incorporation into dental suction apparatus for separating from the suction stream liquid and solid materials coming from the mouth of a patient comprises a housing, a separa-tion chamber in the housing, an inlet for the suction stream into the separation chamber and an outlet for cleaned suction air from the separation chamber. Below the separation chamber there is a smaller collecting chamber below which is a drainage chamber pro-vided with a liquid-solid discharge opening.  In the separation chamber there is a cyclone device into which the suction stream enters tangentially so as to provide a swirling movement.  The suction air then passes up through a central opening defined by the cyclone means.  Also in the separation chamber there is a rotating element in the form of a rotatable float having a stem extending up from the float and provided with vanes associated with the cyclone device so as to rotate the float.  The float also controls valve means so as to drain collected liquid and any solid therein from the separation chamber into the collection chamber when a certain liquid level in the separation chamber has been reached.  When the valve is opened to drain the separation chamber, an outlet valve for the collection chamber is closed so as to preserve suction.  During operation of the separator, except when draining the separation chamber, the collection chamber is vented to the atmosphere.  The outlet for clean air from the separation chamber is provided with a shut-off valve which closes the suction line in the event liquid in the separa-tion chamber reaches an excessive level.
