Abstract: The instant invention relates to the use of ion-pair complexes derived from anionic perfluoroalkyl sulfonates, carboxylates, phosphates and phosphonates and cationic perfluoroalkyl surfactants. Such complexes are capable of reducing the surface tension of aqueous solutions dramatically even at extremely low concentrations, and are useful as wetting, spreading and leveling agents and are especially preferred as components in so-called aqueous film forming foam compositions for fighting polar and non-polar solvent and fuel fires.

Abstract: The object of the invention is a process of manufacturing a sintered compact of sinterable pulverulent material, in which the powder is moulded against a moulding surface and sintered in contact with the moulding surface and in which the pores in at least local areas of the compact are sealed by infiltration with an infiltration material which during a stage of the infiltration process is in liquid form and which by temperature decrease is caused to solidify in the pores, and the characteristic features of the invention are that the moulding takes place on the moulding surface in such a way that the moulding surface is covered with relatively fine-grained sinterable powder which by its own adhesion or by adhesion intensified by additives is caused to form an at least temporarily retained fine powder layer (3) on the moulding surface, and that at least one layer (5) of sinterable coarse powder is applied to the fine powder layer, and that both layers are sintered and infiltration is effected such that the infi

Abstract: Colorectal carcinoma is detected by testing body fluids for the colorectal carcinoma monosialoganglioside identified by monoclonal antibodies produced by fused cell hybrid ATCC HB 8059.

Abstract: A method for the detection and/or determination of an antigen having at least two separate antibody combining sites or antigenic determinants (i.e. a polyvalent antigen) using at least two different monoclonal antibodies which bind to the separate sites is described. In particular the method utilizes Protein A with a carrier to immobilize a first monoclonal antibody which in turn, can bind to one antigenic determinant on the antigen. The second antibody with a label is provided in a solution and binds to the second antigenic determinant on the antigen. A test kit is described for practicing the method. Novel anti-PGH synthase and anti-PGI.sub.2 synthase antibodies and hybridoma cells producing such antibodies are described.

This compound is prepared according to a process which comprises reacting an imidazole compound represented by the following general formula: ##STR2## wherein R.sub.2 and R.sub.4 are as defined above, with carbon disulfides and an alkali metal hydroxide in the presence of a solvent, and if necessary, acidifying the obtained imidazole compound.

Abstract: Methods for improving microstructures of line-of-sight deposited films are described. Columnar growth defects ordinarily produced by geometrical shadowing during deposition of such films are eliminated without resorting to post-deposition thermal or mechanical treatments. The native, as-deposited coating qualities, including homogeneity, fine grain size, and high coating-to-substrate adherence, can thus be retained. The preferred method includes the steps of emitting material from a source toward a substrate to deposit a coating non-uniformly on the substrate surface, removing a portion of the coating uniformly over the surface, again depositing material onto the surface, but from a different direction, and repeating the foregoing steps. The quality of line-of-sight deposited films such as those produced by sputtering, progressively deteriorates as the angle of incidence between the flux and the surface becomes increasingly acute.

Abstract: A novel method for determining when cows are in estrus is disclosed comprising the step of monitoring the vaginal secretions of a cow to determine an increase in the amount of an indicator compound in said secretions. A significant increase in the amount of the indicator compound, concentrations above about 0.1 micrograms per gram of collected secretion, is indicative of estrus. The preferred indicator alcohols have ethyl ester indices of 8.1 to 8.9. In particular these alcohols are methyl-1-heptanols, such as 6-methyl-1-heptanol, or are methyl hydroxy heptenes, such as 2-methyl-7 hyroxy-.DELTA.-3-4 heptene. Alternatively, a cow may be determined to be in estrus simply to ascertaining that the concentration of methyl-1-heptanol is at least 0.1 microgram per gram of collected vaginal secretion.

Abstract: A method of measuring lactic acid or lactate and derivatives thereof in liquids which is extremely versatile and is suitable for use in a number of areas such as the rapid measurement of lactic acid in whole blood, the ratio of lactic acid to pyruvic acid in whole blood, in-vivo measurement of lactic acid and the study of living lactic acid-producing cells. The acid or lactate is measured by reacting the lactic acid with lactic oxidase to produce pyruvate and H.sub.2 O.sub.2. The H.sub.2 O.sub.2 is then measured polarographically. The current produced is directly proportional to the lactate level. Preferably, the lactic oxidase is trapped between two semi-permeable membranes. One membrane is placed in contact with an electrolyte at the tip of an electrode and the second membrane contacts the liquid being tested.

Abstract: Vitamin B.sub.12 in liquid samples, such as human serum or human plasma, is assayed by a competitive binding technique using intrinsic factor and certain labelled vitamin B.sub.12 derivatives. The labelled derivatives are formed from the (d)-monocarboxylic acid isomer of vitamin B.sub.12, which isomer is free from other monocarboxylic acid isomers (and derivatives thereof) of vitamin B.sub.12, by binding to the (d)-isomer, via the carboxylic group, a compound which is itself a label (e.g. an enzyme) or which comprises a label (e.g. a fluorophore), or to which a label is attached (e.g. a histidine ester to which .sup.125 I is attached). The labelled derivatives of the (d)-monocarboxylic acid of vitamin B.sub.12, free from other isomeric monocarboxylic acids and derivatives, are novel and constitute one aspect of the invention.

Abstract: A collapsible medical agent container (10) is disclosed having walls (34, 36, 38) defining a plurality of chambers (12, 14) for containing selected quantities of one or more medical fluids or a dry or encapsulated drug or other reagent in separate sealed condition. Opening means which communicates between adjacent chambers (12, 14) for passage of fluid from one chamber to another, is normally closed by frangible closure (18) which maintains the chambers (12, 14) in separate hermetically sealed condition until flow between the chambers (12, 14) is needed. The frangible closure (18) has an elongated relatively rigid portion (20) which extends into one of the chambers and is disposed within a protective retentive tube (24), and a relatively weakened portion (22) adjacent the opening means.

Abstract: An immersion oil formulation for use in microscopy and related optical fields consists of a blend of a dialkyl phthalate, a butyl benzyl phthalate and chlorinated paraffin. The compounds, when blended, possess a desired optical property including a refractive index of 1.518 or thereabouts and an extremely low fluorescence enabling the immersion oil to be utilized in the field of fluorescence microscopy. The resultant blend also possesses a low toxicity and therefore eliminates all the disadvantages of prior art immersion oils which contain PCBs or which exhibit undesirably high auto fluorescence.

Abstract: An ozone-generating element is disclosed which has a tube ozonizer (1), consisting essentially of an outer metal tube (3) forming one electrode, and of a glass tube (4) which is located coaxially therein and is spaced from it and the inner surface of which is provided with an electrically conductive layer (5) serving as the other electrode. Ozone is formed by pulse discharges with a passive, plate-like spark gap (12) with a defined response voltage serving as a switching element. The tube ozonizer (1) is fed by a low-frequency current source (7) via a high-voltage transformer (9), to the secondary winding (10) of which a storage capacitor (11) is connected.

In this way, it is possible to produce pulse circuits of extremely low inductance which lead to up to a doubling of the total efficiency of ozone generation.
