Abstract: A heat exchanger for a combustion unit having particular use with a water heater. The heat exchanger includes a plurality of generally parallel tubes (12) disposed in a water heater tank (2) in contact with the water to be heated and waste gases of combustion pass through the heat exchanger tubes (12). A turbulator (21) is disposed in each tube (12) to increase the heat transfer from the waste gases to the water in the tank. Each turbulator (21) is formed from a generally flat strip of metal and has a plurality of transverse slits (22) that extend more than one-half the width of the strip and terminate at a base (23). Generally triangular portions or tabs (24, 25) bordering each slit (22) are bent outwardly and the tabs (24, 25) are disposed generally normal to the strip. One tab bordering each slit extends laterally from one side of the strip, while the other tab bordering that slit extends laterally from the opposite side of the strip. The end portion (26) of the strip is bent about the base of a slit (22) to position the end portion (26) at an angle of about 30° with respect to the remainder of the strip. The bent end portion enables the strip to be firmly engaged within the heat exchanger tube so that it will not be displaced during service and yet can be readily removed for maintenance or replacement.

Abstract: 1. Semi-dry process for eliminating acid pollutants contained in fumes, in particular sulphurous anhydride, by a basic pulverulent treatment product of the type in which the said fumes are brought into close contact with the said product, in order that the latter absorbs the pollutants contained in the fumes by chemical reaction after which separation takes place between the gases treated and the product used in the treatment, the purified gases then being capable of being discharged into the atmosphere, characterised in that a quantity of water comprised between about 5 and 15% of the weight of the dry product is added to the dry product, i.e. a quantity of water small enough to keep the product in powder form, before suspending it in a rising stream of the said fumes, carried out in a reaction and drying column.

Abstract: Production of core antigens of the virus HTLV-III and their use in detection of antibodies in sera of AIDS and pre-AIDS patients, and to biochemical and immunological analysis of antigens associated with the virus HTLV-III. The utilization of p24 and p41 core antigens enables a greater specificity of detection. It is shown that antigens associated with the infection of human cells by the virus are specifically recognized by antibodies from AIDS patients. Specifically, HTLV-III isolated from AIDS patients and transformed by occultivation with an HT cell line is specifically detected by antibodies from human sera taken from AIDS patients. The p24 and p41 antigens are used to monitor the precense of HTLV-III in cultured cells and cell-free culture fluids, where virus infection is suspected, and also to monitor antibodies in human sera. The method of detection of antibodies preferred is a radioimmunoassay (RIA), ELISA (an enzyme-linked immuno-sorbent assay) or indirect immunofluorescene assay.

Abstract: The measuring system has two reference marks (R1, R2) which define a datum position and which are arranged at a specified spacing (D) one behind the other on an embodiment of a measure (M). The two reference marks (R1, R2) are sensed by sensing elements (AR1, AR2) which are arranged on a sensing plate (AP) of a sensing device (A) at a spacing (AD) which differs slightly from the mutual spacing (D) of the reference marks (R1, R2). As a result two reference signals (S1, S2) which are slightly displaced in time and which overlap are obtained. After these reference signals (S1, S2) have been triggered, two overlapping reference pulses (Ri1, Ri2) are produced. An AND gate is used to obtain from the two reference pulses (Ri1, Ri2) a resultant reference pulse (Ri) whose pulse time corresponds to the overlap width of the abovementioned signals (S1, S2) (Figure 4). <IMAGE>

Abstract: Peptides which inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads. These peptides may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors. The peptides are cyclic analogs of the decapeptide GnRH wherein there is a covalent bond between the residue in the 4-position and the residue in the 10-position. Examples of such bonds include the disulfide linkage between Cys residues, an amide linkage between a side chain amino group and a side chain carboxyl group, a dicarba linkage between side-chain alkyl groups, and a carba linkage between a side-chain alkyl group and a side-chain sulfhydryl group.
