Title: Joints for reinforced concrete
IPC: E04C5/16
Filed: 1981-02-10
Abstract: The present invention relates to a method for the formation and reinforcement of the joint between pieces of reinforced concrete having steel rods 6 in the concrete structure. Before the concrete is cast, there is placed within each joint zone in the overlapping area of the steel rods one or several joint and anchorage pieces 5, preferably made of steel, plate- shaped or consisting of plate profiles, provided with one or several notches, holes or openings, and placed at a distance from each other substantially transversely to the steel rods. The joint and anchorage piece(s) 5 cast in the concrete are fitted so as to be anchored in the concrete mix surrounding the joint without, however, fastening the joint pieces to the steel rods. Then the joint pieces 5, in the structure, prevent the concrete within the joint from expanding in the plane perpendicular to the steel rods 6 thus safeguarding the joint. <IMAGE>

Title: Method and apparatus for determining the saturation temperature of a solute in a solution
IPC: G01N25/02
Filed: 1981-02-17
Abstract: A test cell 9 contains a specimen of the solution to be tested which is poured over a thin layer (S, Figure 5-b) of fine crystals of the solute deposited on a light-transmitting surface (12%) thereof. As the test cell 9 is heated by a warmer 1, the amount of crystals in the thin layer alters according to the quantity of solute dissolved in the solution, thereby varying the amount of light from a source 4 which is transmitted through the test cell 9 to a detector 21. The saturation temperature can be determined from the output signal of the detector 21 and the temperature of the test cell 9 as measured by a thermocouple 14. The detector 21 forms part of a light- receiving unit 15 which is detachably mounted on top of the warmer 1, and the warmer 1 includes an air seal glass 7 adjacent the unit 15. In order to prevent evaporated solution condensing in a closed space 10 between the glass 7 and the test cell 9, which would otherwise adversely affect the measurements, a continuous stream of pre-heated air is passed through the space 10 by means of ducts 11. <IMAGE>

Title: Improvements in Stays for Windows
IPC: E05D15/46
Filed: 1981-08-19
Abstract: In a friction window stay including a mounting plate (3) and an arm (2) connected together by a friction pivot joint, the joint comprises a rivet (7) which extends through the stay parts (3,2) and is clinched to the underside of the plate (3). The rivet is prevented from rotating relative to the mounting plate (3) by a serrated washer (10), and the clinching pressure applied is sufficient to leave residual loads in the rivet to provide frictional restraint in the joint. The rivet (7) has a coating (13) of low friction plastics material which is applied by a powder coating technique and this coating provides a low friction bearing surface on the rivet head. This provides advantages including permitting simpler construction of the stay. <IMAGE>

Title: Isolation of auxiliary-device drive belt from torsional vibrations of an I.C. engine
IPC: F16F15/173
Filed: 1982-03-01
Abstract: A fluid-shear pulley (10) coupled to the engine crankshaft (12) operates on the principle of fluid-shear transmission of torque through liquid in the chamber (32) for the purpose of isolating torsional vibrations in the hub (14) of the pulley from the outermost, belt-driving portion (20) of the pulley. The fluid-shear pulley (10) thus serves to isolate torsional vibrations in the crankshaft (12) from the driving belt. This isolation of vibrations precludes attainment of resonant modes of vibration in the driving belt, thereby extending the life of the driving belt and making possible the use of a lighter and smaller driving belt. The belt (34), Fig. 2 (not shown). drives an alternator (36), a power steering pump (38) and a power brake pump (40). <IMAGE>

Patent GB-2126450-A (GB)
Title: Time compression of sampled signals
Inventor: CLARKE CHRISTOPHER KEITH PERRY
IPC: H04N5/14
Filed: 1982-09-02
Abstract: The illustrated apparatus is for time compressing a television picture in the horizontal direction. Input samples are fed into an interpolator 5 which produces lower frequency output samples, each formed from a plurality of input samples multiplied by coefficients of an interpolation window function. The low frequency samples are fed to a line store 6 and read out under control of a read address generator at the original samples rate to produce the compressed output samples. A write address generator for the interpolator and line store operates at a rate inversely proportional to the compression factor so that the interpolation aperture function is constant relative to the output samples and the interpolator has a low pass filter characteristic which varies according to the compression factor. To take account of the varying number of input samples contributing to each output sample, the input samples may be multiplied by a factor inversely proportional to the compression factor. Compression may be effected in the vertical direction by using a field store, the input samples being successive lines, or in both directions. <IMAGE>

Title: Production of human monoclonal antibodies
Inventor: BRADLEY DR BENJAMIN ARTHUR
IPC: C07K16/34
Filed: 1983-08-19
Abstract: A process for the production of specific human monoclonal anti-bodies to a predefined antigen or hapten comprises:     a. immunising B lymphocyte cells against the antigen or hapten, b. infecting the immunised B lymphocyte cells with Epstein-Barr (EB) virus, derived from a culture, preferably a mycoplasma free culture, of an EB virus producing cell line, c. culturing the EB virus infected cells on feeder cell layers in a nutrient medium containing at least one anti mycoplasma agent and either at least one anti-T cell immunosuppressant or at least one T cell mitogen to establish continuous cell lines. d. cloning the continuous cell lines by limiting dilution on feeder cell layers in a nutrient medium containing at least one anti mycoplasma agent, e. selecting for clones producing specific human mono-clonal antibodies to the antigen to hapten,   f. growing the selected clones in a culture medium, and   g. collecting the specific human monoclonal anti-bodies.   As an alternative to the use of anti-T cell immunosuppressants or T cell mitogens, T lymphocytes may be removed from the cell population prior to the culture stage. By ensuring that the B cells are mycoplasma free during the culturing and cloning stages and also by suppressing the tendency of T lymphocytes to inhibit or kill the nascent EB virus transformed cell lines, it is possible to clone EB virus transformed lymphoblasts and thereby to achieve long term human monoclonal antibody production.
