Abstract: A vehicle braking system includes a wheel braking unit with an actuator, friction unit, and resilient member. The wheel braking unit is controlled by an operating element. The braking system can be operated in a normal operation mode by a control parameter. The braking system can be operated in a safety mode when the control parameter falls below a threshold value. In the normal mode, the control parameter acts on the actuator so that the actuator establishes a first air clearance in the friction unit. When in the safety mode, a resilient member establishes a second air clearance, which is smaller than the first air clearance.

Abstract: An arrangement and a method are provided for upgrading/downgrading and maintenance (fitting, removal, selection, or repair) of a needle board (1) of a needle machine for nonwoven or needle felt production. The arrangement has at least one tool (2) and has a holding device (3) for holding the needle board (1). The tool (2) may be positioned relative to a needle bore (4) and/or a needle (5) of the needle board (1) by means of a control and drive device and at least one detection device. The arrangement increases the flexibility of the positioning of the tool and allows operations such as selection, repair of the needles by virtue of the tool (2) and the control and drive device being assigned at least one robot (7, 8). The robot (7, 8) is provided with at least one articulatedly mounted tool arm (9, 10) on which the tool (2) is arranged.

Abstract: The present invention relates to novel proteins, in particular membrane proteins or proteins which are firmly associated with the membrane, which are derived from Helicobacter pylori (H. pylori) and which contain the peptide sequence SEQ ID NO:37 according to Tables 1a-1c, or to parts or homologues thereof having a minimum length of ten amino acids, and to their preparation and use as pharmaceutical compositions, in particular as vaccines, or as a diagnostic agent. Based on these data, the gene coding for this protein was also isolated as shown in SEQ ID NO: 36.

Abstract: The present invention relates to a hybrid protein comprising the Pseudomonas aeruginosa outer membrane protein I (OprI) which is fused with its amino terminal end to the carboxy-terminal end of a carboxy-terminal portion of the Pseudomonas aeruginosa outer membrane protein F (OprF), as well as to monoclonal or polyclonal antibodies against this hybrid protein. Both, the hybrid protein and the antibodies directed to the hybrid protein confer protection against an infection by Pseudomonas aeruginosa to laboratory animals or man.

Abstract: The invention relates to malaria-specific nucleic acid sequences, to the expression products thereof, and to the use thereof. A combination of three of the expression proteins whose nucleic acid sequences were isolated by screening a lambda gt11 gene bank with a monospecific antiserum against the protective 41 kD antigen band from P. falciparum protects Aotus monkeys from a P. falciparum infection in model experiments.

Abstract: Protective Plasmodium falciparum hybrid proteins which contain part-sequences of the malaria antigens HRPII and SERP, the preparation and use thereof.The invention relates to hybrid proteins composed of part-sequences of the malaria antigens HRPII and SERP. The HRPII sequence has already proven protective in the monkey model (EP-A2-0 315 085), where a C-terminal region of 189 amino acids has been used in the present invention in the same way as in the preceding protection experiment. SERP was identified with the aid of an antiserum against a protective protein band (EP-A1-0 283 882); the part-sequence used (amino acids (AA) 631-892 or 630-764) contains at least two T-cell epitopes (Roussilhon et al. (1990), Immunol. Letters 25, 149-154). In preferred embodiments, further T-cell epitope-containing regions of other P. falciparum proteins such as merozoite surface antigen I (MSA I or else "195 kd antigen"), amino acids from 100 to 300, are incorporated (Crisanti et al. (1988), Science 240, 324-326).

Abstract: The invention relates to malaria-specific DNA sequences, to the expression products thereof, and to the use thereof.A combination of three of the expression proteins whose DNA sequences were isolated by screening a lambda gt11 gene bank with a monospecific antiserum against the protective 41kD antigen bend from P. falciparum protects Aotus monkeys completely from a P. falciparum infection in model experiments.

Abstract: A cage for an antifriction bearing is an elongate strip of injection molded plastic in the form of individual cage sections. Each section has lateral sides and cross webs which together define a pocket for a respective bearing rolling element. Adjacent cage sections are connected by thin strip connecting webs which are of a length to define an open space between adjacent sections. Respective connecting hooks are defined at the cross webs of each cage section. Following separation of two sections by breaking the connecting webs therebetween, the sections can be later reconnected for defining a complete circular cage by hooking the respective hooks at the cross webs of the neighboring sections to each other.

Abstract: A four-point contact bearing with the largest possible pressure angles and suitable for rotary and swinging movements is disclosed. The rim gaps on both sides of the balls are extremely narrow and offset radially with respect to each other. The cage is segmented and the segments have guide straps which are also offset with respect to each other and extend into the rim gaps.

Abstract: An anti-friction bearing, particularly for large cylindrical roller bearings where the bearing includes an outer ring, an inner ring, cylindrical roller bearing elements between the rings and an annular cage for holding the bearing elements between the rings. The cage comprises a plurality of cage segments, each holding a cylindrical roller bearing. Each segment has a pair of resilient radially inwardly extending noses at both sides thereof and these noses are received in grooves in the inner ring. The axially outer side parts of each segment extend radially to the outer ring and are curved there more sharply than the curvature of the outer ring. The outer side parts also extend to the inner ring and rest there on rounded projections.

Abstract: A roller carriage for larger bearings having a plurality of rollers each of which is provided with recesses in both end areas, and a cage comprising two cage-ring sections which are provided with boreholes, the cage-ring sections being connected with spacer bolts, pins are inserted into the boreholes of the cage-ring sections with the pins extending into the recesses of the rollers. The portion of the pin which extends into the recess of the roller is provided with a convex projection being concentric with the pin serving for axial guidance of the roller, while the radial guidance is provided by the contact between the cylindrical surface of the pin and the borehole inner cylindrical surface of the recess.
