Abstract: In accordance with the present invention, a method of conferring resistance to retroviral infection upon a host cell is disclosed. The method involves transforming the host cell with a vector comprising a polynucleotide directing transcription within the host cell of RNA which (a) is complementary or homologous to a nucleic acid sequence within one or more gene coding regions within the genome of said retrovirus, and (b) is effective to inhibit replication of the retrovirus when the host cell is infected. A method of treatment using cells upon which resistance to infection has been conferred is also disclosed. 
     Nucleic acid constructs including a polynucleotide as previously described are also disclosed. The construct can include a vector as previously described. 
     Cells upon which resistance to infection has been conferred by the above-described methods and their progeny are also disclosed. The progeny of the originally transformed cells "contain a sequence which is descendant from" the polynucleotide previously described. 
     RNA molecules directed by the polynucleotide are also disclosed. Such molecules are (a) being complementary or homologous to a nucleic acid sequence within the genome of a retrovirus, and (b) being effective to inhibit replication of said retrovirus. 
     Finally, conferring resistance to infection by the above-discribed methods using a synthetic polynucleotide which is complementary or homologous to a nucleic acid sequence within one or more gene coding regions within the genome of the retrovirus and is effective to inhibit replication of said retrovirus.

Abstract: On the cart, at least one wheel (2) is provided with a brake which has a brake body (7) which is mounted on the cart chassis (1) and can be moved towards the wheel. So that the brake is of simple design and is suitable for all-wheel braking, the brake body (7) is mounted so as to be movable along a straight movement axis (5) towards the wheel (2) or away from it. The brake body is connected to a rod-like carrier (11) which is oriented at a right angle with respect to the movement axis (5), can be displaced in two guides (10) which are inclined with respect to a plane which intersects the movement axis (5) at a right angle and is arranged so as to be swivellable about the movement axis (5). The inclined guides (10) are arranged on opposite sides of the brake body (7) and axially symmetrically with respect to the movement axis (5). <IMAGE>

Abstract: A method for driving a heating device is indicated, which can be driven in at least two load stages, the design being effected in such a manner that the burning operation of the heating device is always started in the lower or lowest load stage. The control device of the heating device is in this connection designed in such a manner that the heating device is always started in the lower or lowest load stage or heat capacity stage. The control device switches the heating device into the higher or highest load stage when the heating device, upon starting, has first been operated in the lower or lowest load stage. Expediently, the control device contains a trigger circuit for a switching threshold, falling below which brings about switching to the higher load stage. <IMAGE>

Abstract: A method of transferring heat between process liquor streams, such as streams of caustic liquor in the Bayer process for producing alumina from bauxite, uti­lizing a heat pipe arrangement for heat exchange. The process streams respectively pass in contact with one surface of a first heat-exchange wall and one surface of a second heat-exchange wall while being isolated from the second surfaces of the two walls; these second walls are exposed to a closed volume (also isolated from both process streams) containing a heat transfer fluid that vaporizes below the temperature of the hotter process stream and condenses above the temperature of the cooler process stream. The heat transfer fluid vaporizes at the exposed surface of the wall contacted by the hotter stream, and condenses at the exposed surface of the wall contacted by the cooler stream, thereby transferring heat (as heat of vaporization) from the former stream to the latter.

Abstract: A method of forming a semiconductor device on a body of semiconductor material having a first doped region of a first conductivity type, comprising the steps of: forming a stud over the first doped region; using the stud as a mask to form a second doped region of a second conductivity type in the surface of the first doped region adjoining the stud; forming a sidewall of insulating material on the stud; forming a first device contact within the sidewall; and forming a second device contact over the second doped region adjoining the sidewall, such that the first and second electrical contacts are separated by the sidewall. 
     In accordance with an embodiment of the present invention, the step of forming the second device contact includes the steps of forming a layer of conductive material generally conformally over the first doped region and the stud, and then planarizing the layer of conductive material to a height equal to or less than that of the sidewalls. The second contact is thus self-aligned with the first and second doped regions and the first device contact. 
     The method of the present invention can be utilized to fabricate bipolar transistors, insulated gate transistors, and BICMOS logic including both types of transistors. It can further be used to fabricate any other type of semiconductor device which utilizes the self-aligned, closely spaced device regions and contacts of the present invention.

Abstract: For simultaneously measuring the radioactivity of multiple samples arranged in a predetermined array of x rows and y columns, a fixed array of radiation counters arranged in the same array of x rows and y columns so that one of the counters is aligned with each of the multiple samples. Each of the counters has a pair of spaced electrodes; an electrical voltage source connected to the electrodes of all the counters for applying the same voltage across the electrodes of each of the radiation counters in the array; and sensing means connected to the electrodes of each of the radiation counters for independently detecting pulses of electrical current produced by ionization of the gas between the respective pairs of electrodes of each of the radiation counters. For measuring low-energy radiation, the radiation counters are windowless, a flow of ionizable gas is supplied to the counters, and the same flow rate of the ionizable gas is maintained through each of the radiation counters in the array. Preferably the radiation counters are formed in a metal plate that provides shielding to minimize "cross talk" between adjacent samples.

Abstract: A method and device for the assay of alkaline phosphatase in dairy products. A sample of the dairy product is added to a self-­indicating fluorometric substrate comprising a single orthophosphoric ester on a phenolic ring. After hydrolysis of the phosphate radical by the alkaline phosphatase in the sample, the substrate and the sample added thereto are exposed to electromagnetic radiation at a first wavelength. The increase in fluorescence at a second wavelength produced by the hydrolysis of the phosphate radical by the alkaline phosphatase is determined. This increase is linearly related to the activity of alkaline phosphatase present in the sample of the dairy product.

Abstract: Improved chromatographic strip binding assay devices are provided for determining the presence or amount of an analyte present in a patient sample. Assay label reagents interact with capture reagents immobilized in a testing region on the strip substrate to generate a visually detectable image indicative of the test result. The test result images include a minus sign (-) to indicate a negative test result for analyte which image is generated if the suspect analyte is absent in the patient sample and a plus sign (+) to indicate a positive test result for analyte which image is generated if the suspect analyte is present or is present at a pre-determined concentration in the patient sample. The immobilized capture reagents responsible for the location and configuration of the test result images are applied to the strip at an angled orientation with respect to the fluid flow direction of the strip to ensure that sharp substantially complete test result images are formed during performance of the assay. The devices provide substantially self-performing assays having inherently clear test results which are not subject to misinterpretation by the skilled or untrained user.
