An article is decorated by applying a coating to the surface of the article to be decorated, placing over and around the coated article a shrinkable film carrying a desired decoration, shrinking the film over the coated article to transfer the decoration to the article and then removing the shrinkable film leaving on the surface of the article the desired decoration or ornamentation.

Disclosed is a method of welding a diaphragm to the housing sections of a diaphragm-controlled device. The diaphragm and housings are first clamped together to provide a component of force perpendicular to the areas or seat of the housing which hold the diaphragm. An electron beam directed at, above, and below the sandwich edge of the housing and diaphragm causes a weld to be formed in a portion of the seat. The clamping pressure and expansion of the liquified metal forces part of the metal out ...

There are disclosed new biologically active polypeptides containing the following polypeptide segment: Biological activity is generally retained upon substitution of a natural or non-natural amino acid residue for either or both of L-alanyl in the first position and L-seryl in the third position. These polypeptides have the capability of inducing the differentiation of T-lymphocytes as measured by the acquisition of the thymic differentiation antigen Th-1, as well as B-lymphocytes as measured by...

Doors and other closure members for apertures of high temperature plant e.g. coke ovens, are sealed by a heat-resistant putty, conveniently a clay-based putty, applied in a tubular skin, e.g. of polyethylene. On closing the aperture the skin deforms and bursts to distribute the putty to the mating surfaces.

There are disclosed new polypeptide compositions having the following amino acid sequence as the active site: This polypeptide has the capability of inducing the differentiation of both T-precursor cells as measured by the acquisition of the thymic differentiation antigens TL and THY-1 (.theta.), as well as B-precursor cells as measured by the acquisition of receptors for complement, a distinctive marker of B cells. The peptide is thus useful in thymic function and immunity areas such as in trea...

The invention relates to a method of obtaining selected bacterial strains which can convert an assimilable carbon source selected from carbohydrates, methanol, ethanol, glycerin, carbon dioxide and spent lyes from caprolactam synthesis into poly-(D-3-hydroxybutyric acid), selected bacterial strains obtained thereby and their use in producing poly-(D-3-hydroxybutyric acid).

An improved method of decantation in a decanter for separating solid particles suspended in a liquid consists of creating a single thermal barrier located solely in the liquid phase least charged with product to be separated. In the case of a continuous decantation method the thermal barrier is formed between the inlet zone for the mixture to be decanted and the outflow zone for the decanted liquid.

There are disclosed new biological active polypeptides: wherein A is deamino-LYS or LYS; X is a suitable neutral aliphatic amino acid residue; e.g., one selected from the group consisting of SER, ALA, 2-Me-ALA, GLY, LEU, THR, D-SER, D-ALA, D-THR, allo-THR, D-LEU, and SAR; B is GLN-R', decarboxy-GLN, or ##STR1## and R' is a substituent which does not substantially affect the biological activity of the tripeptide. These polypeptides have the capability of inducing the differentiation of T-lymphocy...

Compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each hydrogen or methyl, providing that when R.sub.1 is hydrogen, R.sub.2 is hydrogen, have been found to be useful in relieving allergic symptoms by inhibiting histamine-release from mast cells. They can be used in free form or in the form of pharmaceutically acceptable acid addition salts.

A method for the radioimmunoassay of PGE.sub.1 -type and PGE.sub.2 -type compounds and PGX is disclosed which utilizes antibodies formed against a prostaglandin mimic. Conjugates are disclosed which are formed by attaching a prostaglandin mimic to a carrier molecule. Antibodies are disclosed which are specific against PGE.sub.1 -type and PGE.sub.2 -type compounds, PGH.sub.2, and PGX. Complexes are disclosed which are formed by binding an antibody raised against a prostaglandin mimic with its cor...
