Abstract: A printer blank for a computer system printer is disclosed. The blank has a contiguous pressure adhesive backed label section and may also have a larger plain paper section separated from the label section by a perforation line. The label section is comprised of a plurality of adhesive backed labels and a backing sheet, including a main label portion and at least one smaller auxiliary label. A preferred blank comprises a plurality of auxiliary labels. In use, at least one, but preferably not all, of the auxiliary labels on such a preferred blank are simultaneously removed from the backing sheet with the main label portion. Any auxiliary label(s) simultaneously removed with the main label but not printed upon are readily separated from the main label.

Abstract: A tape dispensing apparatus including a tape container having tape dispensing apertures and a plurality of slots for partitions between rolls of tape. The partitions in the slots are individually formed from portions of boxes for the tapes. The portions of the boxes are integral with the boxes with the tapes therein but have lines of demarcation from the remainders of the boxes for being torn therefrom.

Abstract: A method and device for qualitatively detecting the presence of blood in urine by comparing the color of the urine to a plurality of colors corresponding to the relative blood content of the urine, which enables a health care provider to roughly identify the stage of hematuria and to decide on an appropriate course of action.

Abstract: A cover for servicing holes in automotive service stations consists of a band of pivotably connected support members, the ends of which are supported on the longitudinal hole edges. The band is displaceable longitudinally in opposite directions by at least one motor drive to open and close the servicing hole. During the opening movement the band is moved downwardly at one front end of the longitudinal hole. In order to avoid a broadening of this region of the hole the support members are telescopically assembled and are compressed to a reduced length in this region than in the covering region of the servicing hole.

Abstract: A dental floss applicator is composed of a U-shaped frame of resilient material having a plurality of parallel slits in each one of the pair of holding arms. A plurality of unit lengths of dental floss are fastened in the slits of the arms thereby forming a dental floss curtain. The unit lengths ae provided with caps or beads at their ends and are of equal length. The interspace between a pair of caps or beads of each dental floss unit has an over-dimension with respect to the space between the arms of the frame. The unit is fastened at the frame by turning the unit at least partly around the base of each arm not containing the slit of slits thereby forming a 180.degree.-half-loop or a 360.degree.-whole-loop of the unit. The dental floss curtain provides for a better cleaning operation between the teeth and the new fastening mode guarantees a secure arrangement of the unit at the frame even when the unit is in a slack condition.

Abstract: A unique, high-grade magnetite obtained from fly ash, the use thereof in the cleaning of coal, and low iron content fly ash.

Abstract: In a wrap-around packaging machine by means of which a film loop is wrapped around a plurality of objects, the film passes through a slit provided in a rotary tensioning roller at an end of which a driving pulley is fastened. A rope is wound around the driving pulley. One end of the rope is connected to a traction device and the other end is connected to a restoring device. The tensioning roller by the operation of the traction device can be rotated from a first defined position in which the film freely passes through the slit of the tensioning roller into a second position in which the film is clamped at the tensioning roller and the film loop is tensioned. Then after welding or heat sealing of the film loop the traction device is made inoperative and the restoring device operates in order to move back the tensioning roller into its defined first position.

Abstract: A method of correcting retinal detachments through a small conjunctival incision wherein an expandable member is inserted into Tenon's space, the member is expanded, to form an indentation in the eye, and left in place until the subretinal fluid has absorbed and the retina has reattached.

Abstract: A method of oxidizing alpha-alkylated, benzyl-substituted 2-thiopyridine 1-oxides by admixing the compound to be oxidized, a solvent for said compound, acetonitrile, hydrogen peroxide and a base.

Abstract: A tire and rim assembly with a plurality of dispensing means adapted to release material into the inflation cavity upon operation of the assembly with the tire in the deflated condition to, for example, minimize damage to the tire cause by operation after deflation. The dispensing means are mounted in a balanced array so that each dispensing means lies at least partially in the well of the drop-center rim, and the dispensing means define a clear arc in the well which is adapted to receive portions of the beads during mounting of the tire to the rim. The clear arc of the well may also receive the beads of the tire during demounting of the tire from the rim assembly. Thus, the tire may be mounted to or demounted from the rim assembly by a method which incorporates the ordinary "buttonhooking" procedure commonly utilized with drop-center rims.

Abstract: A composition comprising a gas-expandable polymeric material and an activated hydrazodicarboxylate blowing agent, wherein the activator is selected from nickelbis(3,5-di-t-butyl-4-hydroxybenzoate), a mixture of 2-hydroxy-4-n-octoxybenzophenone and nickelbis(2-oxy-4-n-octoxybenzophenone), nickel stearate, nickel trifluoroacetylacetonate, [2,2'-thiobis(4-t-thiobis(4-t-octylphenolato)]nickel, nickelbis [O-ethyl-(3,5-di-t-butyl-4-hydroxybenzyl)phosphonate], nickelammoniumsulfate, ethylenediaminetetra(methylenephosphonic acid), and hexamethylenediaminetetra(methylenephosphonic acid).

Abstract: This invention relates to the production of ethene with a highly profitable yield by means of fluidized bed catalytic cracking of a mixture containing 0.13 to 50 parts by weight of ethanol to 100 parts by weight of hydrocarbons blend at a temperature between 430.degree. C. and 550.degree. C., and pressure between 0 and 5.0kg/cm.sup.2 gauge in such way that the final gaseous product resulting therefrom has en ethene content between 18.8% and 64% by volume.

Abstract: A glass composition comprising 54-60% by weight of SiO.sub.2, 13-16% by weight of ZrO.sub.2, 12-15% by weight of Na.sub.2 O, 5.5-14% by weight of MnO and 0-7% by weight of CaO, in which MnO+CaO is 11% by weight or more and MnO.gtoreq.CaO, can produce alkali resistant glass fibers which can be used for reinforcing cement products.

Abstract: The object of the present invention is the preparation of ethene in the presence of catalysts using adiabatic reactors at high temperature. Such adiabatic reactors may be used in parallel or be disposed in series or arranged in parallel series assemblies or only a single reactor may be used.The process of the invention allows the use of ethyl alcohol diluted with a sensible heat carrying fluid as feeding material. Said sensible heat carrying fluid is introduced into the reactor simultaneously with the feed, supplying the heat necessary for the performance of the reaction.
