Abstract: INSULATION SYSTEM FOR BUILDING STRUCTURES                 Abstract of the Disclosure Building structures, such as pre-engineered metal buildings, concrete buildings, and combination concrete and metal buildings in most areas require insulation due to the relatively high thermal conductance of the metal and concrete components in the building structure, wall, and roof.      Because of energy conservation measures brought on by fuel shortages and rapidly rising fuel costs, insulation systems used in the past are generally not adequate to meet more stringent standards either recently established or planned for the near future.  The present invention provides an improved insulation system for use in either new construction or in reinsulating existing building structures.  The system of the present invention provides insulation for the areas of the wall or roof between the structural members, between the roof and the structural members and also between all or most of the structural members and the interior of the building itself to reduce significantly the heat loss experienced through the structural members common in con-ventional insulation systems.

Abstract: Abstract of the Disclosure Protective gloves and the like and a yarn comprising a core of a flexible wire alongside an aramid fiber strand or strands and a covering of aramid fiber such as that manufactured and sold under the trademark "Kavlar" by the DuPont Company of Wilmington, Delaware in which the aramid fiber is either spun or filament.  Two aramid fiber strands, either spun or filament, are wrapped around the core with one strand wrapped in a clockwise direction and the other strand wrapped in a counter-clockwise direction wi h the opposite spiral wrapping of the strands serving to secure the strands in position on the core without any other securing means.  The yarn having a flexible core with aramid fiber strands wrapped thereon is used to make protective gloves on conventional glove knitting or weaving machinery and is capable of movement in relation to needle eyes and the like without jamming in the same manner as various natural and synthetic fiber yarn. The yarn having a flexible core with aramid fiber strands wrapped thereon is also used in making various other products normally made of conventional fiber yarn.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure pertains to an optical display apparatus, or fiber optics magnification panel, and a method of making same.  The display apparatus comprises a light input surface defined by one end of each of a multiplicity of elongated optical carrier strands, e.g. fiber optic strands, the one ends being arranged in a relatively closely spaced array of rows and columns.  A light output surface is substantially perpendicular to the light input surface and is defined by the other ends of the strands, the other ends being arranged in a relatively remotely spaced configuration of rows and columns.  Each column of strands extends rearwardly from the input surface to a depth which depends upon the column's position in the order of columns.  Each strand of a column bends sidewardly at its point of greatest depth to an orientation which is substantially parallel to the input surface.  The strands of each column are of different length with each strand of a column terminating at a transverse position which depends upon its row order in the column, such that the other ends of the strands of the columns of the input surface define columns of the output surface which are at less than a right angle with respect to the columns of the input surface.  The result is a compact wedge-shaped display apparatus.  In accordance with the disclosed method, a plurality of substantially parallel relatively closely spaced optically conducting elongated strands, such as fiber optic strands, are wrapped about a spacer element.          At least one additional spacer element is then positioned over the previously wrapped strands and the plurality of strands is rewrapped over the at least one additional spacer element in spiral fashion.  The operation of positioning an additional spacer element over the previously wrapped strands and rewrapping the strands over the additional spacer element is then repeated a desired number of times.  The resultant spirally wound construction is then severed substantially along the plane of the first-mentioned spacer element, and a resultant portion of this severing operation is angularly severed to form a pair of wedge-shaped display panels.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for visually indicating a particular operational condition of a radio transmitter, such as the transmitter being activated or the percentage amplitude modulation of the transmitted carrier.  An electrical or electronic character display module having an integral decimal point display portion is utilized to visually indicate a transmitter circuit condition.  Transmitter activation may be shown by coupling the push-to-talk circuit to the decimal point display.  More specifically, the character display module is oriented to be viewed with the decimal point portion in a superscript position relative to the character.    A method for visually indicating the operational status of a radio transmitter includes the steps of providing a character display module having an integral decimal point, generating a signal indicative of a transmit circuit condi-tion, and activating the decimal point display in response to the indicative signal.  The indicative signal may be a transmitter activation signal obtained from a push-to-talk circuit or it may be a signal indicating percentage amplitude modulation of the transmit signal.  The method also includes the step of orienting the character display module such that it may be viewed with the decimal point portion in a super-script position with respect to the character.

Abstract: AUTOMATIC HEAD TRACKING SYSTEM            ABSTRACT OF THE DISCLOSURE           In an apparatus for reproducing video or other information signals recorded in a track on a magnetic tape or other record medium; a magnetic head or transducer is moved along the track for reproducing the information signals recorded therein while a bi-morph leaf which supports the head receives an electrical drive signal for deflecting the head in a direction transverse to that along the track.  A deflection responsive signal is generated in correspondence to the deflection of the head from a rest position, for example, in response to varying the capaci-tance of a capacitor formed of a fixed electrode and a movable electrode on the bi-morph leaf.  A control circuit for controlling the deflection of the head includes an oscill-ator providing a dither oscillation signal which, on appli-cation to the bi-morph leaf, causes transverse oscillation of the head about a null position, an envelope detector detecting the envelope of the reproduced output of the head, a multiplier for synchronously demodulating the detected envelope by means of the deflection responsive signal so as to obtain a tracking error signal accurately representative of the deviation of the null position of the head from the center of the track, and an adder adding the tracking error signal to the dither oscillation signal so as to provide therefrom the electrical drive signal and by which the null position of the oscillated head is aligned with the center of the track.
