Patent CA-1041411-A (CA)

Abstract: A B S T R A C T     The method is a dual competitive protein binding assay in which serum thyroxine competes with radioactively labeled thyroxine for binding cites on patient and reagent thyroxine binding globulin (TBG).  Preferably, a poly-urethane sponge which may contain an ion exchange resin is used to separate the free from the protein bound thy-roxine.  The assay is based on the capacity of a dilute acid to release thyroxine from its protein bound form in patient serum samples.  Upon pH adjustment, the partially renatured serum proteins compete with added exogenous thy-roxine binding globulin for the liberated serum thyroxine and added radioactively labeled thyroxine.  The value obtained by the assay is indicative of the patient's true thyrometabolic state.  As an example, the euthyroid patient with an elevated thyroxine binding globulin level resulting from pregnancy or estrogen therapy will have a value in the euthyroid range rather than an elevated value.

Abstract: SPROCKET DRIVE AND STRIPPER ARRANGEMENT     FOR COMPUTER FORM FEEDER APPARATUS                    ABSTRACT OF THE INVENTION      A sprocket drive device for a computer form feeder for trans-porting a computer printout web having predeterminedly spaced apertures along the edges thereof along the upper and lower surfaces and about a free end of a copyboard overlying the copy platen of a copying machine, including a pin chain assembly mounted on spaced driven sprocket and idler wheels. The pin chain assembly includes a plurality of predetermi-nedly spaced pins extending therefrom for receipt in the spaced apera-tures of the web.  The pins travel along an endless path between the wheels spaced from the upper and lower surfaces of the copyboard, respecti-vely.  A guide and stripper member is provided on the sprocket drive for guiding the web from the pins to the copyboard surface and vice-versa while avoiding the tearing of the web material about the apertures.  The guide and stripper member includes upper and lower central portions extending between the wheels for guiding the web along upper and lower planes passing through the base of the pins.  End guide portions are provided which are inclined predeterminedly between the central portions and a corresponding copyboard surface spaced from said central portion to lift the web off the pins as the web is moved from the sprocket device to the copyboard and to guide the web onto the pins as the web is moved from a copyboard surface to the sprocket device.  A roller is provided at the free end of the copyboard about which the web passes is mounted for movement toward and away from the end of the copyboard.  Switch actuator means engaged by the roller as it is moved toward the free end of the copyboard due to the slackening in the web engages the armature of the switch mounted adjacent thereto in response to the movement of the roller toward the free end of the copyboard.

Abstract: CONTACTOR DEVICE INCLUDING ARC        SUPPRESSION MEANS       Abstract of the Disclosure An electrical contactor device includes a solid state arc suppression circuit connected in parallel with main relay contacts.  Auxiliary contacts provide gating signals to the arc suppression circuit prior to, during and shortly after the main contacts open.  Protection contacts connected in series with the arc suppression circuit are part of a relay which is actuated by addi-tional auxiliary contacts of the main relay.  The pro-tection contacts prevent the arc suppression circuit from operating during initial closure of the main con-tacts thereby allowing the contactor device to be used in those applications where a high in-rush current is expected.  A delay circuit holds the protection circuit relay contacts closed after the main relay contacts open to permit operation of the arc suppression circuit; the relay contacts thereafter open to isolate the arc suppression circuit and thereby to prevent any leakage current from flowing therethrough and to prevent any false triggering thereof.  A fuse in the protection circuit prevents operation of the contactor device in the event the solid state devices become short circuited.
