Title: New peptide for treating arthritis - contg. aminoacid sequence comprising epitope of fragment from human collagen
Inventor: EMMRICH FRANK PROF DR
IPC: C07K14/78
Filed: 1990-12-20
Abstract: Peptides of formula R1-Ala-Gly-R2-Gly-Ala-Pro-Gly-R3 (I), their fragments, immunologically active derivs. and pharmaceutically acceptable salts are new. In (I) R1 is H, Gly-Phe-Pro-Gly-Gln-Asp-Gly-Leu-, or Gly-Phe-Ala-Gly-Gln-Ala-Gly-Pro-; R2 is Pro-Lys- or -Ala-Thr-; R3 is H, Glu-Arg or -Arg-Pro. (I) are made by, e.g. enzymatic digestion of collagen; recombinant nucleic acid techniques, or solid-phase chemical synthesis. Antibodies directed against the 316-333 epitope can be mono- or poly-clonal, e.g. antibody C1 from the cell line ECACC 89083001. USE - (I), which are derived from the amino acid sequence 316-333 of the alpha1 (II) chain of collagen, suppress arthritis and synovitis. (I) represent an epitope present on the arthritis-inducing CB11 fragment of human collagen II (HCII) and suppress HCII-stimulated proliferation of sensitised T-cells. Such proliferation can also be suppressed by treatment with antibodies directed against the antigen and such antibodies may be included with (I) in pharmaceutical compsns. In an example, human peripheral blood mononuclear cells were stimulated with native HCII at 10 microg/ml, then cloned by limiting dilution to isolate a clone, C9, specific for HCII. 20000 C9 cells and 50000 autologous mononuclear cells were cultured together in presence of 10 microg/ml HCII and various concns. of (I). After 5 days, DNA synthesis in the T cells was measured by determining incorporation of tritium-labelled thymidine.

Patent DE-4109694-A1 (DE)
Inventor: HESS PAUL DIPL ING
IPC: G01F1/26
Filed: 1991-03-23
Abstract: A flowmeter is described which uses the differential pressure method, in particular for hydraulic media. The meter has a spring-loaded reciprocating member, which is guided in a cylinder and which in the event of a throughflow against the spring force releases a radial diaphragm aperture in the circumferential surface of the cylinder. The reciprocating member is coupled to an electrical displacement sensor, and the output signal of the displacement sensor is a measure of the throughflow. The effective diaphragm aperture essentially has the shape of an isosceles triangle whose apex faces the closing direction. The side, opposite the apex, of the diaphragm aperture is formed by the end face of the spring-loaded reciprocating member. The electrical output signal of the displacement transducer has the same progressive characteristic as the throughflow characteristic of the diaphragm aperture. The effect of the agreement between the two progressive characteristics of the throughflow and displacement sensor is that a linear electrical output signal is emitted. <IMAGE>

Patent DE-4134956-A1 (DE)
Inventor: KLEMM GUENTER WILLI PROF DR
IPC: E21B4/14
Filed: 1991-10-23
Abstract: A pneumatic hammer is provided with an adjusting means (37) dependent on the supply pressure, which adjusts the stroke length of the working piston (16). Thereby, the same pneumatic hammer may be operated both at low and high supply pressures. With high supply pressures, either the early ending of the acceleration phase or the early start of the compression phase or the shortening of the working cylinder shortens the stroke length. Thereby, the pneumatic hammer performs impacts with a substantially constant single-impact energy, regardless of the supply pressure. High supply pressures increase the impact frequency. This results in a considerably improved efficiency at a high drilling capacity, a reduced wear and a reduced risk of ruptures of the components of the hammer.
