Abstract: A building structure, particularly a road bridge structure, has an upper part (6-10) adapted to carry traffic, and a lower part (2) supporting the upper part. The two parts are separated by a non-adhesive, low friction membrane (1) having hood portions (4) fitting around anchorage blocks (3) projecting upwards from the surface of the lower part. The upper part comprises a course of pavement blocks (7) in which blocks are omitted to form a void around each anchorage block (3), the voids being filled with concrete (9). At least one asphalt layer (10) is laid on top of the pavement blocks (7). Liquids penetrating through the upper part are prevented by the membrane (1), including the hood portions (4) from penetrating into the lower part (2) and are drained off above the membrane (1). Horizontal forces resulting from traffic are transmitted via the asphalt layer (10), the pavement blocks (7), the concrete filling (9), the hood portions (4) and the anchorage blocks (3) to the lower part (2).

IPC: F01D17/14
Abstract: 881,882. Centrifugal pumps and compressors. SULZER FRERES S.A. Dec. 8, 1958 [Dec. 23, 1957], No. 39514/58. Class 110 (1). A centrifugal pump or compressor comprises a first ring 4 concentric with the rotor shaft and forming a part of one of the walls of the diffuser of the pump or compressor, the flow cross-section of the diffuser being adjustable by varying the distance S between the diffuser walls by axial movement of the first ring 4, a second ring 13 concentric with but axially spaced from the ring 4 and restrained from axial movement, and at least three motiontransmitting members 12 extending between the two rings and arranged at the same angle of akew α in relation to the rotorshaft, the rings 4, 13 being relatively rotatable and the members 12 being arranged to convert relative rotation of the rings into axial movement of the first ring 4. As shown, the ring 4 is held against push members 11 and the members 12 by a spring 10 and the excess of the pressure between the diffuser walls over that behind the ring 4. Each motion-transmitting member 12 has two spherical ends, one located in a guide passage 14, and the other in a recess 16 in the ring 13. A space 19 containing the motion-transmitting members 12 is sealed off from the diffuser by metal bellows or other sealing members 20 and the first ring 4 has a sealing ring 7. The second ring 13 is rotated by a worm 17 engaging a toothed segment 18 and rotation of the ring will displace the members 12 as in the upper diagram of Fig. 2, which shows the mechanism with the skew angle α at a maximum. The arrangement described compensates for the increasing percentage reduction in flow cross-section for a given movement of the ring 4 as the distance between the walls decreases. An adjusting screw 22 may be provided for adjusting the effective length of the member 12.

Abstract: An arrangement for damping and absorption of sound in rooms. The purpose of the invention is to provide a sound damping even at very low frequencies e.g. 50 Hz and simultaneously improve speech comprehension in the entire room by reduction of the resonance time. Another purpose is to be able to vary the acoustic absorption and in that way even vary the resonance time over the entire part of the frequency area. This has been achieved by the fact that the sound absorbents 14 in the form of plates mats or similar are arranged at an angle with at least one corner area (11) formed by the walls 12 and ceiling 13 of the room in the corner area 11 behind the absorbent 14 an air volume is trapped so that the absorbent due to the sound influence has a membrane effect. The inclination and for position of each absorbent 14 can be varied individually or in group.

The vertical side plates (1, 2) have parallel first and second longitudinal side edges (1a, 1b) and end edges (1c, 1d) comprising a first part (5, 6) at right angles to a first longitudinal side edge (1a) and, on the remainder of the width of the side plate (1, 2) a second part (7, 8) inclined with respect to the opposite longitudinal side edge, said second parts diverging against said second side edge to form angles therewith corresponding to the roof inclination. The top and bottom members (3, 4) are formed as curved or bent plate profiles of a cross-sectional shape corresponding to respective ones of the opposed end edges (1c, 1d) of the side plates (1, 2). After assembling, the side plates and top and bottom members (1-4) of the panel assembly into a rectangular frame structure adaption to the actual roof thickness may be performed by cutting-off from said members at the external side of the panel assembly.

Title: Method for identifying active domains and amino acid residues in polypeptides and hormone variants
Inventor: WELLS JAMES A
IPC: C12Q1/68
Filed: 1989-10-30
Granted: 2001-10-16
Abstract: The invention provides methods for the systematic analysis of the structure and function of polypeptides by identifying active domains which influence the activity of the polypeptide with a target substance. Such active domains are determined by substituting selected amino acid segments of the polypeptide with an analogous polypeptide segment from an analog to the polypeptide. The analog has a different activity with the target substance as compared to the parent polypeptide. The activities of the segment-substituted polypeptide are compared to the same activity for the parent polypeptide for the target. A comparison of such activities provides an indication of the location of the active domain in the parent polypeptide. The invention also provides methods for identifying the active amino acid residues within the active domain of the parent polypeptide. The method comprises substituting a scanning amino acid for one of the amino acid residues within the active domain of the parent polypeptide and assaying the residue-substituted polypeptide so formed with a target substance. The invention further provides polypeptide variants comprising segment-substituted and residue-substituted growth hormones, prolactens and placental lactogens.
