Abstract: A system (50) includes a labeling machine (52) and a digital data processing system (54) connected to the labeling machine (52). A cutter (56) of the labeling machine (52) has a shaft (58) with a mark (60), which is sensed by a sensor (62). The sensor (62) supplies shaft (58) information on line (64) to digital data processing system (54). The digital data processing system (54) supplies control signals on line (64) to feed roll (66) stepper motor (67). The digital data processing means (54) is also connected to an optical sensor (76) by line (78). The optical sensor (76) senses the position of position mark (74) on the labels (70), which is correlated with the position of shaft (58) in order to feed the labels (70) to the cutter (56) at the proper rate so that the labels (70) are always cut at the kerf (72) between each label (70).

Abstract: A fractional calculator (10) has a keyboard (12) with numeral keys (18) and denominator keys (20). Through use of the numeral keys (18) and the denominator keys (20), fractional inputs may be entered into the calculator and calculations carried out on the inputs through use of function keys (22). A decimal/U.S. toggle key (26) allows the calculator to be used in either a conventional decimal mode or a fractional mode. When the calculator is used in a fractional mode, key (30) is used to differentiate between integers and numerators of fractions entered by means of the numeral keys (18). Key (28) may be used to distinguish between feet and inches in mixed unit entries during fractional mode operation. Display (14) includes indicators (38, 39, 40, 42, 44) for different modes of operation and different types of entries.

Abstract: An adhesive composition for attaching semiconductor die to a substrate of a semiconductor device package includes a crosslinkable resinous polyimide, and an aminosilane crosslinking agent. For applications where backside contact to the semiconductor die is desired, the composition also contains finely divided conductive metal, such as silver flakes. When used in a novel process in which the adhesive composition is placed on the semiconductor device substrate prior to gelling, outgassed, a semiconductor die is placed on the outgassed composition, and the composition cured, the resulting semiconductor device package meets military specifications with a substantial cost reduction.

Abstract: An apparatus (10) for proportioning and mixing liquid components of a solvent has a chamber (12) with a rotatable piston (24) mounted in the chamber. The chamber has a plurality of liquid component inlets (18, 20 and 22). Rotatable piston (24) has a notched portion (30). Relative lengths of time the notched portion (30) is opposite the inlets (18, 20 and 22) determine the proportion of liquid components supplied at each inlet port (18, 20 and 22) in the solvent mixture. Rotation of the piston (24) in the chamber (12) mixes the liquid components introduced through the inlet ports (18, 20 and 22). Stepper motor (32) is controlled by microprocessor (52) driven control system (50) to position the notched portion (30) at the inlet ports (18, 20 and 22) for variable lengths of time.

Abstract: An assembly (10) for supporting a post (12) with respect to an aperture (14) in concrete (16) includes first and second opposed surfaces (32). Each of the surfaces (32) has one end shaped to fixedly engage an end of the post (12). Each of the surfaces (32) has a second end extending longitudinally beyond the end of the post (12). The extending ends of the surfaces (32) are configured to enter the aperture (14) and have opposed camming shapes (38 and 44) which wedge the extending ends of surfaces (32) into tight engagement with the aperture (14) as the extending ends move further into the aperture (14). The method includes providing such an assembly, driving the assembly to position one end of the surfaces (32) against the post (12) and the extending end into aperture (14), so that the camming surfaces (38 and 44) push the extending end of the surfaces (32) against the aperture (14). The surfaces (32) are then fixedly attached to opposing sides (24 and 26) of the post (12) by screws (22).

Abstract: A nutcracking apparatus (50) has a tube (56) dimensioned and configured to allow nuts to be propelled along the tube (56). An opening (58) spaced circumferentially around the tube (56) is angled to direct air along the propelled direction of the nuts. A blower (62) is connected to supply sufficient air to the openings (58) to create suction for pulling a nut into the tube (56) past the openings (58) and then to push the nut through the tube (56) after it has passed the openings (58). The nuts are propelled against a rotating impact roller (70), which cracks each nut and moves the cracked nut out of the path of the travel to prevent interference with a succeeding nut. Air from the tube (56) propels the nut shells through outlet (72) of chamber (68), while the nut meats are deposited on screen (74).

Abstract: An attachment (10) mounted on underside (16) of a toilet (14) lid (12) has a covering end (18) dimensioned and configured to extend over a flushing handle (20) of the toilet (14). The attachment (10) serves as a guard to prevent the toilet (14) from being flushed without lowering lid (12) to rest on seat (22). A hazard to small children from an open toilet bowl of the toilet (14) is therefore eliminated.

Abstract: A multiple function, multiple digit meter includes a light directing structure (18) for providing uniform illumination to digits (14) of display (12). A block (20) of clear plexiglass has a surface (22) facing the display (12). Edges (24, 26) of the block (20) have notches (27, 28) for receiving incandescent bulbs (30) to direct light into the block (20). The block (20) has a back surface (32) which curves upward moving away from the bulbs (30) toward the center (34) of the block (20). Surface (32) is reflective to direct light toward the display (12). The configuration of the surface (32) causes an increasing percentage of light received at the surface (32) from the lamps (30) to be reflected toward the display (12), with increasing distance from each lamp (30). The panel meter (40) has a first manually actuated means (70) for selecting one of the multiple functions of the meter (40) and a second manually actuated means (72) for changing a displayed value of a selected function.

Abstract: A variable delay memory system (200) has an addressable memory means (66-1) having a data input port and a data output port. A counter (206) is connected to supply a write address on bus (212) for storage of data supplied to the data input port on bus (64-1). A subtracter means (214) is connected to receive the write address as one input on bus (210) and a second input proportional to a desired delay time on bus (72-1). The subtracter means (214) is connected to supply its output as a read address on bus (216) for data stored in the memory means (66-1) to be supplied at the data output port on bus (76-1).

Abstract: In a microprocessor having independent address and data paths and other pipeline architecture features, a control unit utilizes a PLA which stores microcoded instruction sequences. These sequences permit an operator at a console to read data from and write data to all the internal registers, any external memory location or the program counter. In addition, the PLA contains microcode which enables programs in external memory to be loaded from any location in memory and run by command from the console as well as to enable the operator to halt user program execution, read the pertinent internal registers, and then continue program execution such that single step execution for debug purposes is possible.

Abstract: A power transistor array integrated circuit includes an array of transistors, each having an electrode connected in common to a conductive line forming a part of the integrated circuit. The electrodes of the transistors are spaced along the conductive line and have a decreasing length in a given direction along the conductive line and have a decreasing length in a given direction along the conductive line. The conductive line has a corresponding increasing width in the given direction. The decrease in length of the electrode and the increase in width of the conductive line are such that the electrodes and the conductive line form a generally rectangular shape. Differences in turn-on voltage for the transistors resulting from the differences in their electrode length tend to compensate for voltage drop in the conductive line, thus giving uniform outputs from the transistors in the array.

Abstract: An enclosure for a loudspeaker has a housing formed of sound reflecting material having opening dimensioned for mounting of a loudspeaker therein. A body of sound deadening material is disposed within the housing. The body of sound deadening material defines a bell-shaped chamber having a top and a bottom. The top of the bell-shaped chamber is located at the loudspeaker opening and the bottom of the bell-shaped enclosure is remote from the loudspeaker opening. The enclosure is preferably used in combination with a novel sinusoidal waveform energy reflector. The reflector has first and second surfaces each having an exponential cross-section and being reflective to the waveform energy. The first surface terminates in an apex pointing at a source of the waveform energy, such as a loudspeaker. The second surface intersects the first surface around a perimeter of the first surface.

Abstract: An ultrasonic imaging system (50) has an array (52) of transducer elements (54-1 through 54-21) for receiving ultrasonic signals reflected from within an inhomogeneous object (16) being examined. The system (50) has a means (80, 84, 88, 94) connected to generate an image in response to the ultrasonic signals. A cross-correlator (70) is connected to compare the signals received by the transducer elements (54-1 through 54-21). An output addressing circuit (130) is connected to inhibit or otherwise modify gain of selected ones of the signals based on the comparison to reduce multipath ultrasonic wave interference, refraction or obstruction image distortion or degradation. A preferred ultrasonic imaging array (52) for this purpose and for time delay image distortion correction has a plurality of segmented, annular transducer elements (54-2 through 54-21). The elements (54-2 through 54-21) are formed as sectors of circles with substantially equal arc lengths.

Abstract: A gaitor (10) has an upper fabric portion (12) configured to be wrapped around a leg of a wearer. The fabric portion (12) has a zipper (40) for fastening the portion (12) around the leg. The fabric portion (12) has a lower edge (26). A rubber gasket (14) configured to conform closely to a shoe (16) worn by the wearer has an upper rim (24). The gasket (14) is fastened by means of a seam (28) around the lower edge (26) of the fabric portion (12). The lower edge (26) of the fabric portion (12) is folded up to lie against the upper rim (24) of the gasket (14). The seam (28) fastens the folded up lower edge (26) against the upper rim (24) of the gasket (14). A structural tape (60) formed from a nylon sheet die cut into a strip with alternating wide and narrower portions (64 and 66) is fastened along seam (28) at toe (54) of the gaitor to prevent folding of the rubber gasket (14), which is otherwise prone to occur at the toe (54), resulting in tearing of the seam (28) when stressed.
