Abstract: A profiling system comprising a profile member having a profile guide element. The profile member is displaceable along a first straight axis. A working head is fixedly secured relative to a work support surface and spaced relative to the profile member. The working head and the support surface are mounted on a head support frame displaceable along a second straight axis extending transversely to the first axis. Support members are secured relative to the profile member and displaceable therewith to retain and displace a material to be worked on by the head. A follower element is fixedly secured to the head support frame and displaceably engaged with the profile guide element. The head support frame is displaced along the second axis in response to angular deviations from the first straight axis as defined by a path delineated by the profile guide element as the guide element is drivingly displaced along the first axis.

Abstract: The invention relates to a heating element for a heated chair which can be used as a covering material for the heated chair or which can be laid under the covering material or which can be draped over an ordinary chair to convert it to a heated chair. In accordance with the invention, the heating element has a glass fibre fabric layer made of intermixed glass fibre strands. An electrical resistance wire which consists of a core of glass fibre strands with a resistive wire wound around it, forms an undulating pattern in the glass fibre fabric layer, and top and bottom layers of thermoplastic material are heat fused or adhesively laminated to the glass fibre fabric layer. A metallic foil layer is applied to the side of the bottom layer which is remote from the glass fibre fabric layer. The heating element also includes a control for controlling the power delivered to the resistance wire. The said control is a simple dual proportional control which regulates the energy usage of the heating element.

Side beams on the frame have inwardly extending flanges for engaging under the flange of the tote box and cover permitting them to be slid into place separately or to be removed for filling or cleaning. Adjustable connectors between the beams permit width-wise adjustment for different sized containers. The device is specially applicable to suspending tote boxes and covers from wire supply carts.
Abstract: A self-extruding fastener having a head provided with a cross groove, a stem having two screw threads and a tapering portion terminating at a sharp pointed forward end adapted to form a guide opening in a thin sheet of metal. A third screw thread generates in a position midway between said two screw threads and in a portion where the stem ends and the tapering portion begins, and extends to the pointed forward end, while the two screw threads disappear in the tapering portion. Therefore, the self-extruding fastener according to the invention comprises three sections, that is, two screw thread section, three screw thread section and one screw thread section.
Abstract: An electrical heater device for heating a clinical mirror. The device comprises a housing having a top, bottom and side walls to define a hollow enclosure. Two spiral coiled electric heating elements are secured in the housing with their heat radiating surface spaced apart and facing each other in juxtaposition to provide concentrated heat in a mirror locating space therebetween. An opening is provided in the top wall in alignment with the mirror locating space through which the mirror can be inserted into the mirror locating space. A switch is positioned in alignment with the mirror locating space below the heating elements. The switch has an activating contact on an upper face thereof located in alignment with the opening in the top wall and the mirror locating space for activation by a clinical mirrow when the mirror element of such is inserted into the mirror locating space.
Abstract: An improved band saw blade for cutting hard ferrous or non-ferrous articles, wherein the band saw blade comprises an elongated, flexible, continuous ribbon having a back edge and a toothed edge, the ribbon having a sinoidal pattern in the plane of the ribbon, the wavelength and pitch of the ribbon being selected to enhance the cutting of the article but is selected to avoid chatter based on the rate of speed of travel of the ribbon, the pressure applied to the ribbon during the cutting and the average length of the cut to be made in the article to be cut. A method of constructing a band saw blade with a sinoidal pattern including the steps of successively squeezing portions of the saw blade or ribbon alternately near its back edge and near its toothed edge, whereby the blade is formed with a continuous wave pattern.
Abstract: A mitten having a capability of being used as a glove which includes a knitted, elongated, tubular member having one end closed and formed with elongated finger and thumb portions forming a glove. A waisted wrist portion is connected to the glove, and a tubular mitten portion extends from the wrist portion in the opposite direction. The mitten is open at its free end with an overlapping flap covering the free end and a thumb portion formed in the mitten portion such that when the glove is worn, the mitten portion can be folded over the glove with the thumb of the mitten portion coinciding with the thumb portion of the glove and the overlapped portion covering the opening at the end of the tubular mitten over the fingers.

Abstract: A system for mechanically reproducing language characters in a cursive form in accordance with the natural style calligraphy of the language. Written letters are characterized by "links" with preceding and following characters, and mathematical rules describe the cursive script in terms of the form each letter takes dependent upon the preceding and following characters. The system includes input means for inserting characters, one at a time, and for providing coded representations of the characters. The coded representations are fed to decoder means which has as an output a selected combination of concatenation properties applicable to the character. Analyzer means analyzes variables dependent on the concatentation properties of a successive string of characters which comprise a character under consideration, a preceding character and a following character.
Abstract: A digital logic circuit, hereinafter referred to as an element, of which an interconnected plurality together with their connections to a control unit comprise a learning machine which synthesizes a boolean function of n variables as the result of a training procedure.Each element may operate as a two-input, one-input combinational circuit of one of four logical types, where the type is determined by the current internal state of the element. All four types are such that a (ZERO,ZERO) input pair gives rise to a ZERO output, and a (ONE,ONE) input pair gives rise to a ONE output, while the particular operation realized is determined by two function value units which compute suitable outputs under the (ONE,ZERO) and (ZERO,ONE) input pairs to the element.Three different species of element are described differing in their computation of heuristic responsibility. The "global search" species is useful when the function to be synthesized is not constant; there is a convergence theorem related to this species.
