Abstract: ABSTRACT         Broadcast Signal Recognition System and Method The method for the automatic electronic recognition of a program unit broadcast by radio waves includes the formation of a plurality of reference signal segments from the program unit and the processing of such segments to obtain digitized reference signal segments which are then normalized and stored.  When the program unit is broadcast, the broadcast signal is processed to  generate successive digitized broadcast signal segments which are correlated with the digitized, normalized reference signal segments to obtain correlation function peaks for each resultant correlation segment.  The spacing between the correlation function peaks for each correlation segment is then compared to determine whether such spacing is substantially equal to the reference signal segment length.  Also, the RMS value coincident with each correlation function peak is determined and the pattern of such RMS values coincident with the correlation function peaks is compared with the pattern of the RMS values of the normalized reference signal segments.

Abstract: ELECTRICAL CONNECTORS  WITH PROTECTIVE HOOD  ABSTRACT OF THE DISCLOSURE     A protective hood for a rectangular electrical connector is described in which the hood is provided with flexible sidewalls.  A locking member and cam member is provided adjacent the free edge of each sidewall near the opening to the recess in the hood into which the connector is positioned.  During assembly of the hood to the connector, the cam members flex the sidewalls away from the connector to prevent the locking members from locking onto the connector. When fully assembled, the cam members release the sidewalls to allow the locking members to lock onto the connector with an audible "snap."           The hood may be unlocked and removed from the connector by manually flexing the hood sidewalls away from the connector.  In one form of the invention this may be done by manually applying force to one end of the bottom of the hood.

Abstract: -??-CONDUIT BENDER WITH ANGLE INDICATIONS               Abstract of the Disclosure A tool for bending conduit comprises a body that has a bottom shoe portion which is curved along its length and in which there is a downwardly opening groove that is symmetrical across its width to a plane of symmetry, a tubular handle supporting socket projecting up from the shoe with its axis in said plane, and a hook portion in front of the shoe.          Integral ridges on the body define sighting lines contained in a plane parallel to said plane of symmetry, each such line designating attainment of a predetermined bend angle when it is perpendicular to a supporting surface.  The ridges define upper line segments on the socket that diverge downwardly from a point on the axis about which the shoe is lengthwise curved and lower line segments on the shoe that are length-wise aligned with respective upper line segments.

Abstract: ABSTRACT     Electrophotographic imaging method particularly for duplicating a photographic image carried by a silver halide emulsion bonded to a transparent base.          The transparency is brought into intimate engagement with the charged photoconductive surface with the base in contact with the charged photoconductor.  Radiant energy is passed first through the transparency emulsion and then across the base in contact with the charged photo-conductive surface selectively to discharge the surface producing a right-way reading latent charge image which is toned for visibility.

Abstract: SYSTEM FOR TREATING PARALYZED PERSONS      Abstract of the Disclosure Apparatus and method for therapeutic treatment of persons having   paralyzed legs.  The apparatus and method make use of four sets of transcutaneous electrodes which are placed above the iliac and quadriceps muscles of the paralyzed person.  The person is seated upon an exercycle, and a series of pulsed stimulation signals are applied to the electrodes to cause coordinated contraction of the iliac and quadriceps muscles.  This causes pedaling of the exercycle by the paralyzed legs.  A position sensor senses the position of the pedals and transmits an indication thereof to a computer which generates control signals for stimulation driving circuits connected to the stimulation electrodes.  A pair of paddle controllers are connected to the computer for manual adjustment of the stimulation amplitude.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE THICKNESS OF DEVELOPER ON AN APPLICATOR, SUCH AS A MAGNETIC BRUSH, IN ELECTROSTATIC REPRODUCTION          ABSTRACT     A magnetic brush developing system for electro-static duplication using a monocomponent developer con-trols the thickness of the developer on the brush such that the necessary amount of developer is applied to the photosensitive surface which carries the latent electro-static image.  A capacitive sensor in the form of a rigid plate of conductive material is spaced closely adjacent to the surface of the roll on which the mag-netic brush is formed.  The dielectric constant depends on the thickness of the developer in the magnetic brush and is detected by the capacitive sensor.  The capaci-tance of the sensor is converted, into a pulse train the duty cycle of which is modulated in accordance with the change in capacitance, by a circuit arranged on a cir-cuit board in close proximity to the sensor to provide a compact structure which is not subject to perturbations which could effect the capacitance presented by the sensor.  The circuit controls the supply of developer to the brush in response to the duty cycle of the pulse train by causing the dispensing of the developer when a duty cycle change corresponding to the decrease in the thickness of the developer in the brush occurs and ter-minating the dispensing of the developer when the thick-ness becomes excessive thereby providing a layer of developer of consistent thickness in the brush so that copies of desirable optical density are obtained.

Abstract: ABSTRACT OF THE DISCLOSURE     A linerless double-coated pressure-sensitive adhesive tape of the prior art is wound directly upon itself into a roll that can later be unwound without delamination or offsetting of adhesive.  The novel tape differs from the prior tape in that the pressure-sensitive adhesive at each of its faces is a substantially solvent-free, crosslinked alkyl acrylate polymer and can be aggressively tacky for uses requiring high-performance adhesion.          Also provided is a composite of two pressure-sensitive adhesive tapes which are releasably adhered together adhesive face to adhesive face and then put to individual uses.  The tapes are separable because their facing adhesives are substantially solvent-free, crosslinked alkyl acrylate polymers which can be aggressively tacky for uses requiring high-performance adhesion.

The mat is then removed from the support member, and reduced (16) in thickness into a more dense mat of fibers.  The dense mat (14) is then again subjected to a brazing temperature (18), to form a final product having unusual strength qualities.
