Abstract: A masking material for protecting the surface, or finish thereon, of a product, such as an automobile, during assembly, storage, shipment or transport including a bottom layer of plastic film adapted to have the lower surface thereof adhered to the surface to be protected, a cushioning layer disposed in superposed relation to the bottom layer and having lengthwise and widthwise dimensions smaller than the corresponding dimensions of the bottom layer such that the bottom layer protrudes for a predetermined distance beyond the periphery of the cushioning layer, and a top layer disposed in superposed relation to the cushioning layer and the bottom layer and having lengthwise and widthwise dimensions greater than the corresponding dimensions of the cushioning layer, the top layer being adhered to the cushioning layer and the bottom layer.

Abstract: A foam in bag cushion precursor is disclosed that is particularly useful for manual operation. The cushion precursor comprises a bag formed of two sheets of flexible plastic film material closed on all four side edges; a frangible seal that defines separate interior cells in a portion of the bag; a first foam precursor composition in one of the interior cells; and a second foam precursor composition in another of the interior cells. One of the cells has a nonfrangible seal wall other than one of the side edges for directing the contents of the cell to mix with the contents of the other cell before the mixed contents enter the remaining portion of said bag.

Abstract: A single tube Coriolis flowmeter having a balance bar that enhances the flowmeter sensitivity to material flow. The balance bar's design lowers its second bending mode response to have a frequency that may be lower than the flow tube resonant drive frequency. The lowering of the second bending mode frequency of the balance bar enables the Coriolis response of the vibrating flow tube with material flow to extend force from the flow tube through a brace bar to the balance bar. These Coriolis forces induce Coriolis-like response vibrations in the balance bar because of the lowered second bending mode frequency of the balance bar. The Coriolis response of the flowmeter is enhanced since the Coriolis-like response of the balance bar is out of phase with and is additive to the Coriolis deflection of the flow tube.

Abstract: A single tube Coriolis flowmeter of enhanced flow sensitivity in which material flow induces Coriolis deflections in a flow tube and Coriolis-like deflections in a balance bar vibrationally coupled to the flow tube. Both the Coriolis deflections and the Coriolis-like deflections have a phase shift determined by material flow and are used co-adjuvantly to derive material flow information. The flowmeter achieves a constant flow sensitivity over a range of changes in material density by 1) varying the flow sensitivity in a first direction under control of the ratio between the drive mode vibration amplitude of the flow tube and the balance bar and 2) varying the flow sensitivity in an opposite direction under control of the ratio between the Coriolis deflection amplitude of the flow tube and the Coriolis-like deflection of the balance bar. The drive mode vibration amplitude ratio varies with changes in drive mode frequency caused by changes in material density.

Abstract: A bag dispensing system providing plastic bags from a roll of bags where one end is attached to the top of the next bag by perforation lines with a slot therebetween. The roll of bags provides a core having an indexing member on at least one end. The dispenser comprising a wire frame formed into channels to support the core. The channels include a core retaining member for restraining the core in the channel. The dispenser includes at least one brake attached to a support member and disposed at an angle thereto to provide tension to the edges of the roll of bags as the core passes through the channel passageway as bags are removed from the roll. Spaced apart from the support is a separating tongue. The tongue engages the slot regardless of whether the bags are drawn over or under the tongue.

Abstract: A modular parts container including multiple upstanding side panels registerable to a platform having a generally flat supporting surface with perimeter panel engaging recesses to receive elongated tabs extending from the side panels. The panels have interlocking end fittings slideably disposed within one another for progressive selective interengagement. The platform has multiple support legs in staggered spaced side by side relationship. Panels can be stocked one on another and selectively removed for container access and tear down.

Abstract: A scraper plane and plane insert that substitutes, in the place of a conventional plane iron or blade and cap iron, a bracket formed by bending sheet mild steel to form two arms, one of which is secured to the frog and the other of which holds a scraper blade in a substantially upright position. Small adjustments in the angle between the scraper blade and plane sole can be made by actuating a micro-adjustment mechanism that forms a bridge between the support arm and securing arm of the bracket.

Abstract: A Coriolis effect densimeter which produces density output data of improved accuracy by embodying the principal that the natural frequency of a vibrating tube filled with material decreases with an increase in the material mass flow rate. High accuracy output data is achieved by measuring the density and the mass flow rate of material through the vibrating tube, correcting the measured density to compensate for the effect of the mass flow rate, and correcting the mass flow rate correction of the density measurement for changes due to temperature.

Abstract: Disclosed is a method of aligning a plurality of probes to a plurality of contacts, the contacts being arragned in a pattern on a substrate. The method includes the steps of powering one of a selected pattern of probes or a like pattern of selected contacts such that upon the selected patterns being in coincidence, the plurality of probes will be in contact with predetermined contacts on the substrate. This is accomplished by providing a circuit path through all of the other probes or contacts which are not powered and then bringing the plurality of probes into contact at random with the contacts of the substrate and then moving one of the substrate and probes until the selected patterns coincide as by indication of a completed circuit path between selected patterns.

Abstract: It has been found that compounds having a stereochemically unencumbered access to a nitrogen-nitrogen bond have antiviral activity in extremely low dose ranges. Hydrazine, hydrazine derivatives and related compounds have been found to be active in protecting animals against disease caused by both DNA and RNA type viruses at doses of about 250 picograms to 250 micrograms per kilograms of host body weight.

Abstract: A bar graph device has a column of 200 cathodes connected in three sets which are energized in sequence to give a visible gas discharge which travels up the column from a reset cathode. The cathode drive is from a clock which also drives a sawtooth which is compared with the input signal. When equality occurs, the anode is de-energized to extinguish the discharge. Cathode drive continues until all cathodes in the column have been energized. Divide-by-200 circuitry ensures proper resetting. Scale markers are provided in the display itself by splitting the divide-by-200 circuit as shown, and using the pulses from the divide-by-5 section to fire a one-shot and a disable gate for, say, three clock pulses. This effectively freezes the system after every five pulses passing through the gate, resulting in the display in the device dwelling on every fifth cathode; these cathodes, therefore, appearing brighter than the rest.

Abstract: A sheathing system is provided for covering structure of a building. The system includes elongated panels that can be arranged edge to edge to form a generally planar surface which can be moisture tight for convenient washing. The panels are rigidly supported from the building structure so that said generally planar surface does not move if subjected to the pressure of a jet of water. The panels can run transversely to rigid elongated stringers which are spaced from the building structure so that they can clear irregularities on the building structure. Between such stringers and the building structure are spacers that are of relatively short length measured along the lengths of the stringers, and that can slide along the stringers to suitable locations for connection to the building structure. The spacers may be rigid spacers.
