Abstract: Anticaries ingredients for corn and cane sugar containing confectioneries such as syrups, mints, and candies, and for oral health products such as mouthwashes, lozenges, toothpastes and toothpowders are presented. The anticaries ingredients include aliphatic mono and dialdehydes having from 2 to 6 carbon atoms, aliphatic monoaldehydes having from 6 to 12 carbon atoms, and polyaldehydes such as dialdehyde starch and dialdehyde galactomannan gum. These ingredients in concentrations of about 5 percent by weight or less have been found to effectively inhibit the growth and acid production of oral microorganisms and thereby reduce the incidence of dental caries.

Abstract: Disclosed is a solid state wristwatch of relatively small size useful as a small man's watch or even a ladies' watch. It incorporates an arm responsive inertial switch for energizing a light emitting diode display. The display forms part of a timing module and is mounted on one side of a laminar ceramic substrate. Mounted on the other side of the substrate is a combination timepiece and calendar circuit chip. Printed circuits are formed on non-contacting surfaces of the substrate laminations and interconnected by conductive pins. The entire timing module is staked to a plastic frame which also carries the watch batteries, quartz crystal, trimmer capacitor, switches, and other watch components.

Abstract: An electronic music synthesizer is disclosed in which the sound producing chain includes a voltage-controlled oscillator, band-pass filter, low-pass filter, and amplifier in which selected control currents are supplied to low impedance points within the synthesizer circuit from a resistor matrix. The synthesizer produces sounds approximating different acoustic musical instruments or having different tonal qualities by the application of a predetermined voltage to one of fifteen input columns of the resistor matrix with selected other columns being grounded. The currents provided by the resistor matrix in combination with other externally generated currents control the center frequency and bandwidth of the band-pass filter, the cutoff frequency of the low-pass filter, the gain of the voltage-controlled amplifier, the time constants of transient contour currents used to control the filters and amplifier, and the waveform produced by the voltage-controlled oscillator.

Abstract: The apparatus includes a conveyor table having pairs of press heads mounted on its opposite sides. Strips of sheet metal stock from coils are fed through respective die sets for punching integrally extending teeth in the metal strips and the connector plate stock thus formed is fed into the respective paths of movement of upper and lower press platens. The platens are movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of joints formed by wooden frame members disposed on the conveyor between the press heads. Simultaneously with the pressing operation, the die set punches additional teeth into the strip. Upon completion of the pressing operation, a feed mechanism locates predetermined lengths of connector stock with struck teeth between the press platens for the next cut and embedment operation.

Abstract: Disclosed is a device for loading and unloading modules relative to a pressure vessel and utilized in reverse osmosis systems. The device includes an elongated support for receiving the modules, a fluid actuated cylinder located at one end of the support and a clamp at the opposite end of the support for clamping the support to the open end of the pressure vessel. As each module is disposed on the support, the cylinder is actuated to extend its piston whereby the piston head displaces the module along the support into the open end of the pressure vessel. Additional modules are similarly loaded into the pressure vessel whereby the modules are serially arranged within the pressure vessel.

Abstract: Disclosed is a device useful by an orthodontist for expanding a human palate. It comprises a stationary body secured to an anchor tooth on one side of the palate and a movable block secured to an anchor tooth on the other side of the palate. A helical spring urges the two apart to expand the palate. A keeper holds them together until they are fixed in place by the orthodontist.

Abstract: The flat chord truss jig assembly includes a jig pad carrying two pairs of laterally spaced elongated guide bars. Releasable clamps are provided along the opposite outer edges of the pad and engageable with the outermost pair of bars. The innermost pair of bars are connected by longitudinally spaced rods reverse threaded at opposite ends for threaded engagement with the bars whereby rotation of the rods moves the innermost pair of bars toward and away from one another to introduce similar camber in each innermost bar. An end locator plate is positioned between each pair of bars at opposite ends of the truss. The chords and diagonals of a flat chord truss are disposed between the pairs of bars on opposite sides of the jig pad and connector plates of the type having integrally struck teeth are prepositioned at the joints between such chords and diagonals. The jig assembly is moved through a press whereupon the teeth of the connector plates are embedded into the joints to complete a flat chord truss.

Abstract: Disclosed is a broad band amplifier for use as a preamplifier in TV receiving systems and in other applications where broad band amplification is desired. A ferrite directional coupler is used to negatively feed back a portion of the output of an amplifying stage to its input.

Abstract: Disclosed is an artificial firelog comprised of a flammable body typically formed of a particulate wood and wax mixture preferably with salts added for flame color. In a preferred embodiment, by a coextrusion process, a groove is formed along the outer surface of the body and extends substantially its entire length. The groove is filled with gelled starter fuel. The log is preferably formed with at least one substantially flattened side with the gelled fuel filled groove located just above the flattened side whereby the log can be situated with its flattened side on the fireplace grate or andirons and the gelled fuel filled groove located along the lower preferably front, face of the log thereby facilitating the log's fast lighting characteristics. The log is provided with an over-wrapper having an inner low or medium density polyethylene coating and which over-wrapper is heat sealed about the log. When lighting, the over-wrapper is initially lit and this also ignites the gelled fuel.

Abstract: The connector plate has a plurality of slender nail-like teeth struck to project at right angles to the plate for embedment into adjoining wooden members. The teeth are struck in longitudinal rows with the teeth in each row being staggered longitudinally relative to the teeth of next adjacent rows. The teeth in every second alternate row are struck such that the slots left thereby in the plate extend from the teeth in like directions while the teeth in the next adjacent alternate row in are struck such that the slots left thereby in the plate extend an opposed longitudinal direction to the slots formed in adjacent alternate rows. The teeth in the rows between such alternate rows are formed in longitudinally spaced pairs with each pair of teeth struck to jointly define a slot in the plate, the teeth being located at opposite ends of the slot.
