The shapes of the symbols have iconicity, eusymmetry, and frame consistency with respect to the quadrants of Cartesian coordinates and the alignments of the shapes of the symbols are symmetry positional with respect to the axes of the Cartesian coordinates. The combination and configuration of the symbols are chosen so that the symbols can be positioned by a selected combination of flips, rotations, and counterchange operations to display and perform all sixteen binary connectives.

Abstract: An attitude change alarm for securing articles from theft or other undesired movement. The alarm includes a case having a wall which defines a hollow interior. Resistive elements are maintained within the wall in spaced relationship with each other and in common communication with an electrically conductive surface on the outside of the wall. An electrically conductive member is fixedly maintained in the hollow interior in constant contacting engagement with a conductive fluid which makes selective engagement with certain of the resistive elements. When the alarm is moved, a current is transmitted from the conductive coating through the resistive elements, fluid, and member, and is passed to a transformer which gates an SCR into conduction, activating the alarm. Various geometrical configurations of the attitude change alarm are presented, each having specific attributes associated therewith.

Abstract: A system for the remote identification of objects using near-field electromagnetic coupling between an interrogator a transponder and a receiver in which a reply carrier at a subharmonic of the interrogation frequency is obtained by regulating, with minimum energy loss and synchronously with the interrogator signal, the energy exchange process between the transponder coupling element and a complementary storage element, and further varying, also with minimum energy loss and synchronously with the resultant oscillation waveform, the said energy exchange process so that the reply carrier becomes modulated with an information bearing code, the modulation rate being not constrained by the transponder tuned circuit bandwidth.

Abstract: A tire press bag well is insulated with at least one envelope. The envelope extends substantially around the bag well within the bag well housing and can be inflated. The envelope, in addition to its insulating properties, can have insulation thereon and the ends of the envelope can be fastened to itself. The configuration of the envelope, once installed, desirably conforms to the shape of the bag well housing. Since heat is applied to a tire press via the bag well, insulation thereof considerably reduces heat loss as well as reduces cure time.

Abstract: Apparatus for performing tests for determining the validity of a paper purported to be a valid instrument is presented. Fundamentally, the invention comprises a tray for receiving a paper offered as a valid instrument and maintaining the same in sliding relationship between a light source and reticle. A photocell is operatively connected to the reticle and senses light passing from the light source and through the paper and reticle. The output of the photocell is applied to an operational amplifier having a dynamic feedback network and the output of this amplifier is characteristic of both a grid pattern upon the paper and the optical density thereof. This output is then passed to an amplifier circuit which establishes an optical density domain and is operative to pass a signal only if the paper falls within such domain. This output is then passed to appropriate integrating and comparator circuitry to ultimately determine the validity of the paper.

Abstract: In the field of security validators, slot acceptors have been known which transport paper offered as a valid security past a testing station. Previously known acceptors have been susceptible to defeat by mosaics, stringing, shocking, photocopy duplication, and the like. Additionally, known acceptors have operated in an analog mode, relying uon rudimentary test functions. The invention herein overcomes the problems of the prior art by presenting an acceptor having a note path (18) characterized by changes of direction (22,24), and which is secured at each end by means of unique gate assemblies (78,98). A plurality of sensors (148-152) are positioned along the note path and are controlled to take a multitude of data samples from the paper as it passes along the path. The data is digitized (236) and used for solving complex transforms, the results of which are compared against results obtained from known valid securities to determine the authenticity of the paper offered.

Abstract: [Hydroxy(organosulfonyloxy)iodo]arenes are synthesized in neutral organic solvents by the reaction of ring-substituted [hydroxy(organosulfonyloxy)iodo]benzenes with iodoarenes via ligand transfer. The produced compounds are reacted with (triorganosilyl) arenes or (trihalosilyl)arenes in neutral organic solvents to produce diaryliodonium salts. The diaryliodonium salt synthesis proceeds in regiospecific fashion, aryliodination occurring at the point of attachment of the silicon atom in the silylarenes.
