Patent CA-1073387-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to the induction of interferon production in the cells of living organisms, including human beings.  According to the invention, nucleic acid complexes, such as the polyriboinosinate and polycytidylate complex (rIn-rCn), are modified to yield unpaired bases (uracil or guanine) along the polycytidylate strand which render the complexes more readily hydrolyzable by nucleases present in living cells.  The modified complexes retain their ability to stimulate interferon release by the cells but are rendered more vulnerable to destruction within the cells, the modified complexes being significantly less toxic than the original complexes.  In addition, polyinosinate strand now has been prepared to contain 5-16% 2'-O-methyl inosinate residues, designated as (rI5-20,2'-MeI)n.  The new complex (rI5-20,2'-MeI)n? rCn, exhibits  100-fold more activity than rIn rCn as an interferon inducer in human cells.

Abstract: Abstract of the Disclosure A pressure roller is composed of a plurality of roller sections, one of said roller sections having a greater dia-meter than the residual ones.  All sections are carried by a common shaft, but the sections having a smaller diameter are eccentrically located on the shaft and freely rotatable thereabout.  In this way, by turning the shaft the smaller sections may selectively become situated in such a relation versus the larger ones that the periphery of all sections acquire a common tangent plane in view of an opposed surface.          The opposed surface may be a xerographic drum or belt and the pressure roller, after applying a suitable electric DC poten-tial to it, may serve as part of transfer device adapted for being used for the transfer of toner image towards a paper passing between the nip of the pressure roller and the xero-graphic drum or belt, whereby the effective width of the pressure roller is a function of the width of the paper.

Abstract: ABSTRACT OF THE DISCLOSURE             A multichamber cuvette for maintaining in independent and separate condition at least two reactants until such time that it is desired to mix them for reaction with each other and a reactant liquid sample while in the cuvette for analysis in the cuvette, and a method of use of such cuvette.  There is provided a cuvette body of a suitable plastic defining at least two chambers interconnected by a passageway of relatively small cross section having at least the end portion thereof of capillary size to prevent under many circumstances, as by surface tension, accidental mixture of liquid reactants in the chambers.  If there is a substantial head of liquid in one foreign object, sufficient to break such surface tension, an air lock in the passageway when the latter is below the liquid levels in the chambers prevents such accidental mixture.  A baffle in the passageway enhances separation of liquids and/or solid substances in the chambers.  The chambers are open-topped, and a unitary probe-wiping multi-ply laminated cover of a type puncturable by a probe extends over the chambers closing them from the external environment.  The laminated cover tends to be self-closing with reference to such punctures.  One ply is of metal foil to act as a vapor seal and has an undercoating of a heat sealable material compatible with the body material and sealed thereto.  The top ply is of a moisture-absorbent material which is secured to the foil ply by an intermediate plastic ply.

Title: Acoustic emission system for welding flaw detection
Inventor: CLARK ROBERT N
IPC: G01N29/14
Filed: 1977-02-28
Granted: 1981-01-06
Abstract: ABSTRACT     A system for flaw detection during a continuous welding process uses a transducer to provide a signal burst for each acoustic burst from an article being welded.  The signal burst is amplified and filtered to pass frequencies between about 100 and about 550 KHz. The ring-down counter counts signals of the filtered signal burst.  The first signal of the filtered signal burst initiates a timing circuit that times out to provide a reset pulse to reset the ring-down counter.  If the decimal count exceeds 100 but does not exceed 1000, the ring-down counter operates circuitry to provide a latched signal to an output of a flip-flop to enable a gate before the counter is reset by the reset pulse of the timing circuit.  That reset pulse is also pro-vided to the gate to provide at its output a pulse representing one filtered signal burst having more than 100 and no more than 1000 signals during the timing operation.  The pulses from the gate are inputs to a pulse counter in the counter mode and a retriggerable monostable multivibrator that, if not retriggered by the next pulse before a predetermined time, resets another flip-flop and resets the pulse counter.  If the pulse counter counts a predetermined number of pulses before it is reset, it sets that another flip-flop to provide a signal to an alarm device that turns on a light indicating that there is a weld flaw.

Abstract: FOLDING TABLE WITH LOCKING HINGE                    Abstract of the Disclosure An improved lockable hinge for a folding table of the type having table surface members which fold to a vertical storage position and to a horizontal usable position.  The table is locked at an intermediate position when moving towards the usable position from the storage position by a pivoting lock bar which swings by gravity into a recess formed in a hinge plate on one half of the table and is jammed between the recess and a tab formed in the matting hinge plate on the other half of the table.  A handle provided for the locking bar bending away from the adjacent edges of the two table surface members can be pivoted to withdraw the bar from the recess and around the tab as the table moves to the usable position.  Release of the handle allows the locking bar to fall back into the recess engaging the other side of the tab to lock the table in the down position.  A preferred embodiment allows the same hinge plate design to be used in both table halves.
