Abstract: The picking lever (11) with low mass inertia and high strength, having a hub part (12), an arm (13) and an end part (14), consists of thermoplastic reinforced with high-strength fibres. This is composed of a plurality of layers laid on one another in the form of prepregs or semi-finished products, the layers having different fibre orientations and being essentially parallel to the plane of movement (21). In the arm (13) the longitudinal components of the fibre orientations predominate, with a gradual transition to the hub part (12) and to the end region (14) which have an approximately isotropic distribution of the fibre orientations. Consequently, the mechanical strength of the composite material can be utilised as effectively as possible and be matched to the locally differing load directions occurring. Moreover, a simple, reliable and cost-effective production becomes possible. …<??>The picking lever is suitable especially as a rocker lever in a projectile-shuttle weaving machine in order to increase the weaving capacity and reduce the energy consumption. …<IMAGE>…

Abstract: A method of sliding mode control which decreases the steady deviation from the control target and which improves control stability by adapting the control system to a change in the system parameter. The processor in a digital servo circuit of the servo control system calculates position deviation (ε), speed deviation (έ), a value of the switch-over plane (s) and a value of an integration element      on the switch-over plane (100 to 102, 107, 113) based on an instructed position (Θr) and an actual position (Θ). The processor further calculates a first term and a second term of switch-over quantity (T1) according to a calculation formula determined depending upon the switch-over plane, position deviation and positive or negative sign to which the value of the integration element is corresponded (103 to 115). Then, based on a calculated value of switch-over quantity (T1) that is equal to the sum of the first and second terms and that satisfies the Liapunov stabilization condition, a torque instruction (T) is calculated that is sufficient to converge the characteristics of the control system to the switch-over plane (s = 0). As a result, the control system does not lose stability even when the system parameters undergo a change.

Title: Fungal cell wall material with flocculant properties, method for its production.
Inventor: EDEBO LARS
IPC: C12N11/02
Filed: 1990-10-08
Abstract: The invention relates to fungal cell wall material containing hexosamine and exhibiting a positive Zeta-potential at a pH value of 7 when disintegrated to a particle size less than 20  mu m. The fungal cell wall material may be derived from a fungus selected from the phylum Zygomycota or the phylum Dikaryomycota. The fungal cell wall material is manufactured by a process including a) physical disintegration and/or delipidation with an organic solvent, and b) de-proteinization and depletion from nucleic acid by alkali treatment and/or by treatment with an enzyme. The fungus material may be used in processes to recover or remove negatively charged products such as proteins, nucleic acid or microbial cells from water based media. It may also be used as a biological carrier to immobilize enzymes and cells.

Abstract: An installation for fastening railway sleepers, especially to steel or concrete bridge decks, has a ribbed plate (16) mounted on the bridge deck (6), which plate comprises an upper rib (18) running transversely to the sleeper (4) and lateral ribs (30, 32). The sleeper is provided at the end with clamping fillets (12) which can be fixed on the ribbed plate (16) with the aid of a clamping profile (42) attachable to the rib (18) and clamping profile fixing means (48). The ribbed plate (16) is bolstered by a slide plate (34). Levelling plates (38) can be provided beneath the slide plate in order to adjust the height. A lateral adjustment is possible by the use of elongated holes in the ribbed plate (16), via which the ribbed plate is connected to the bridge deck by means of a bolt fastening. The interval between the guide ribs (30, 32) is greater than the width of the sleepers so that strains in the bridge can be compensated for. <IMAGE>

Title: Variable area obstruction gas flow meter.
Inventor: STUPECKY JOSEF
IPC: G01F1/40
Filed: 1990-11-05
Abstract: A flow meter including a variable area obstruction which is mounted in a conduit. Inputs to a differential pressure transducer are positioned in the conduit on opposite sides of the obstruction to measure fluid pressure differential across the obstruction. In one embodiment, a sleeve is secured within the conduit thereof substantially separated from the conduit so as to prevent fluid condensation on the sleeve, and to create a dead end pocket between the conduit and the sleeve for collecting liquids from the conduit end preventing them from contacting the obstruction. The variable area obstruction comprises an elastic membrane that includes first, second and third leaves which extend into the flow stream and are compliant to fluid flow so that an increase in flow rate increases the deflection of the leaves and increases the through flow area through the obstruction. The first leaf is secured at a fixed end adjacent a first portion of the interior surface of the conduit and extends in a first direction to a free end preferably positioned adjacent a second portion of the interior surface of the conduit opposite the first portion. The second and third leaves are located adjacent opposite sides of the first leaf and extend from their fixed ends toward their free ends in directions which are generally opposite to the first direction.
