    Abstract: Glass compositions have been found which, with a low linear thermal expansion coefficient of 33.9-53.2.times.10.sup.-7 /.degree.C. at 20-300.degree. C. will pre-stress to a much higher extent under similar prestressing conditions than known glasses of the same thermal expansion, and which consequently result in crumbling under forced fracture. The glasses possess the following properties: the transformation temperatures (Tg) are between 566.degree. and 660.degree. C., the softening temperatures (Ew) are between 821.degree. and 845.degree. C. and working temperatures are between 1211.degree. and 1370.degree. C., the temperature differential Ew-Tg being 232.degree. to 298.degree. C., the ratio .alpha.'/.alpha. of the thermal expansion coefficient above Tg (.alpha.') to expansion below Tg (.alpha.) being between 4.1 and 9.4 and the formation comprising:______________________________________ SiO.sub.2 61.60-79.50 percent by weight B.sub.2 O.sub.3 1.00-10.50 Al.sub.2 O.sub.3 2.50-14.00 Na.sub.2 O 1.50-6.

  • Patent number: 4257811
    Abstract: Optical glass is disclosed which has an increased resistance to solarization and irradiation as well as little or no undesirable coloring. This glass is designed to exhibit as many properties having optimal values as possible. The silicate glass used is free of alkaline earth metal oxides and incorporates CeO.sub.2 and both zinc and strontium ions in very small concentrations. The latter two materials further improve the solarization and irradiation resistance properties of the glass. Furthermore, as the zinc and strontium ions are effective when used in low concentrations, they serve to minimize any undesirable glass coloring.

  • Patent number: 4247533
    Abstract: Sheep antiserum developed against the human glycohemoglobin, Hb A.sub.1c, distinguishes this fraction from the major component Hb A.sub.o. Partial cross relativity is observed with Hb A.sub.1a and Hb A.sub.1b, as well as with analogous glycohemoglobins from mouse and dog hemolysates. The reactivity of the hemoglobins with this specific antiserum is abolished by the reduction of the keto group of the sugar ligand. The immunological specificity displayed provides the basis of a quantitative assay for Hb A.sub.1c, which is suitable for studies of clinical and experimental diabetes.

  • Patent number: 4245051
    Abstract: A plasminogen proactivator and a corresponding activator has been isolated from mammalian and avian, especially human, plasma which is characterized within a given species as a single, electrophoretically and immunologically homogeneous protein. The activator acts as a catalyst to initiate fibrinolytic activity in plasma and is therefore useful in controlling clotting which occurs, e.g. in venous thrombosis or arterial occulsion, and in diagnosing conditions which predispose to thromboembolic phenomena. The proactivator has a long useful in vivo half life and can be used to provide a reservoir for maintaining the fibrolytic potential of blood.

  • Patent number: 4241909
    Abstract: Document stacking apparatus for continuously stacking a plurality of documents in the sequential order in which they are fed into the apparatus is disclosed. Motor driven feed rollers feed the documents into the apparatus and along a predetermined path defined by guide plates and a deflector. A stacking bed is provided for supporting the documents in a stacked arrangement and a moveable baffle is mounted upon the stacking bed for defining a stacking cavity with the guide plates. The stacking bed is inclined with respect to a horizontal plane and is also provided with an inclined slot. A follower is fixedly secured to the baffle and slidably disposed within the slot whereby the baffle is gravity-biased toward a first position so as to normally minimize the stacking cavity. The baffle is also movable, under the influence of the incoming documents to be stacked, against the gravity-bias toward a second position so as to expand the stacking cavity and thereby accommodate successive documents to be stacked.

  • Patent number: 4229061
    Abstract: An electrical adapter or connector (10) comprises a block of insulating material (12) and a plurality of moveable contact pins (16) which are positioned within recesss (14) found in the block. Each of the pins includes an upper mating electrical contact surface (18) and a screw (22) for conductively securing the pin to a wire (30). Springs (28) are loosely positioned at the bottom of each of the recesses in order to continuously bias the pins outwardly from the upper surface (15) of the insulating block. The pins are prevented from moving out of the recesses by set screws (32) placed within longitudinal bores (31) of the block or by attaching each spring at one end to the bottom of one recess and at its opposed end to the bottom of a contact pin. Each upper mating contact surface (18) is preferably conically shaped, so as to receive a mating contact pin (17) having a complimentary shaped conical surface (19) in aligned electrical engagement.
