Abstract: The connectors comprise a connector anchored in an end-face blind bore in a wooden beam, which includes the following features: a cylindrical insert whose diameter corresponds approximately to the diameter of the blind bore and which has peripheral recesses or grooves formed tangentially in the cylinder surface; bar dowels which are incorporated perpendicular to the longitudinal plane of the connector and the wooden beam and which penetrate the recesses or grooves of the insert so as to lie at least partly within the outline of the cylinder surface; some of the bar dowels are provided with a wooden thread; a rigid sealing compound body in the blind bore, which surrounds the cylindrical insert and the bar dowels and forms with said parts a composite block, and a connecting member formed on the connector for anchoring in, or connection to, another body. This connector makes it possible to realize wood constructions with high load-capacity.

Abstract: Reinforced concrete slab and girder building structures incorporate shearing connectors with lengthwise support parts to which lengthwisely spaced, transversely extending, rigid load transfer plates affix. A girder structure having one or more lengthwisely extending girders is provided and the shear connectors are fixed to the girders near their support walls below a deck for supporting the slab, the shearing connectors being positioned so that portions of the load transfer plates and support parts project above the girder structure and deck to receive compression forces in the slab which are transferred by the connectors to the girders. The lengthwisely extending connector support parts have connections for carrying a series of lengthwisely spaced rebar rods which embed in the slab when it is poured and transfer compressive load forces to the transfer plates.

Abstract: For power transmission between a wooden beam and another building component, for example another wooden beam, a blind bore and a vent bore opening into the bottom of the bore are formed in the wooden beam. An insert body is pushed into the blind bore. This body comprises two spaced end plates whose outer cross-section corresponds to the cross-section of the blind bore, and at least one, preferably four, power-transmitting bars whose ends are welded to the opposing sides of the end plates. Bar dowels are then driven in from the side of the wooden beam so as to penetrate spaces between adjacent power-transmitting bars. Epoxy resin is then pressed into the blind bore from the outside until the entire blind bore and preferably also part of the vent bore are filled in with resin. When the resin has hardened, the resin body and the steel parts form a composite body. Connecting members may be attached to the outer end part.

Abstract: The present invention relates to a cryopump having a gas bearing formed in a clearance seal between a piston and a cylinder. The gas bearing is formed by forcing pressurized gas from a gas plenum through orifices to the clearance seal.
