摘要:
The reactor device comprises a horizontally-disposed housing (1), at one end of which there is disposed an inlet (4) for supply of the medium, and at the other end of which there is an outlet (5) for the reaction products. Within the housing (1) of the reactor device a rotor (1) is rotatably mounted. The rotor (8) has a hollow cylinder (9), which is provided with openings (10) and annular members (12, 13) for moving and transporting the medium. The hollow cylinder (9) is partly immersed in the free-flowing medium, the openings (10) in the hollow cylinder (9) ensuring additional admixture of the medium.

A room temperature superconductor having a metal thin film with negative susceptibility coated upon a substrate. The thin film is covered by a protective coating which prevents it from oxidizing. In one embodiment of the invention multiple layers of chromium with negative susceptibility value separated by a protective coating are mounted upon the substrate to provide a sandwich like structure having increased current carrying capacity.

An ultra thin film with very low electrical resistance is produced by forming a substrate of a substrate material which forms a metastable bond and depositing a conducting film on the substrate in a vacuum environment in which a base pressure is reduced to a value below 10−5 Torr. The film is a metal, metallic alloy, or multilayered film which includes at least one metallic layer. A 0.1 nm thick manganese film deposited in this way on a germanium substrate has a resistivity which at room temperature is lower than the resistivity of metal films of aluminum and copper with the same thickness prepared the same way.

The invention relates to an industrial truck (10) having a load displacement device (12, 14, 16, 18) which comprises two device parts (12, 14, 19, 20), which can be substantially displaced relative to one another along a displacement axis (V), and at least one piston/cylinder system (30, 60) for the purpose of providing a force required for a relative displacement of the device parts (12, 14, 19, 20), a piston (32) of the piston/cylinder system (30, 60) being connected to one of the device parts (14, 20), and a cylinder (34, 64) of the piston/cylinder system (30, 60) being connected to the respective other one of the device parts (12, 19). According to the invention, the cylinder (34, 64) is rigidly connected to the device part (12, 19) associated with it such that torques acting about a torsion axis (T) extending in the cylinder longitudinal direction (L, L′) and/or tensile and/or compression forces acting substantially in the cylinder longitudinal direction (L, L′) and/or bending moments acting about a bending axis (W, W′) extending substantially orthogonally with respect to the cylinder longitudinal direction (L, L′) can be transmitted from the device part (12, 19) at least to a longitudinal section (34b) of the cylinder (34, 64), in particular of the cylinder casing.

A hydraulic axial piston motor (1) of the bent axis type comprises a drive shaft (3) fixedly connected with a drive disk (4), a cylinder block (10) which is provided with mutually parallel cylinder bores (9) on a circular line in which pistons (8) are arranged to run, and the pistons being connected in an articulating manner with the drive disk (4), which is pivotally bearinged about a transverse axis (37) and arranged adjacent to the drive disk (4). A flow control disk (16), which on its side facing the cylinder block (10) is provided with two arcuate flow control slots (24 and 25) and is also provided with a cylindrical outer side (23), whose central axis of curvature coincides with the pivot axis (37) of the cylinder block (10) and is bearinged in a terminal plate (15) secured to the housing and which is provided with supply and drain ports (21 and 40), and which disk is provided with recesses which are at least partly in alignment with the supply and drain ports and are connected with a flow control slot. In order to ensure that the motor does not run away on pivoting out of the stall range towards a range with larger pivot angles, on its cylindrically curved side (23) the flow control disk (16) is provided with a flow control edge (20) delimiting an aperture (29) and which on pivoting the cylinder block (10) towards 0.degree. increasingly closes the supply port (21).

The invention relates to an industrial truck having a first load-bearing component (12) and a second load-bearing component (14) which are provided such that they can move in relation to one another for the purpose of carrying out a conveying movement, a sensor scale (22) being provided on one of the load-bearing components (14) (scale load-bearing component) for the purpose of detecting the relative movement between the two load-bearing components (12, 14), and a sensor (24), which is designed to detect the sensor scale (22), being provided on the respective other load-bearing component (12) (sensor load-bearing component). The industrial truck is characterized in that the sensor scale (22) is designed integrally on the scale load-bearing component (14) such that a section (14a) of the scale load-bearing component (14) itself is the sensor scale (22).

A semiconductor device which exhibits reduced electromigration which includes an electrically conductive support member having a thin film of chromium overlaying the conductive support and a layer of semiconductor material overlaying said chromium film. The invention also includes a method of reducing electromigration and resistance and resistance in conductive supporting layers of semiconductor devices by forming a chromium layer over at least one surface of the conductive support layer of the device. The conductive support may be copper or aluminum with a semiconductive layer of germanium or silicon.

A method for filling and closing off a two-chamber container with different filling materials includes two sealing steps for the closing-off procedure, the first chamber being filled with the first material under sterile conditions and closed off over a first partial seal with a covering sheet, after which the second chamber is filled with the second material and closed off by means of a second partial seal with formation of a fully sealed two-chamber container.
摘要:
The proposal is for a device for injection molding plastic items enclosing hollow spaces with which a further pressurised medium like air, gas or a fluid can be introduced through a hollow needle (5) at a point differing from the nozzle into a mould (1), the mould hollow or cavity (4) of which can be filled with molten pastic through a nozzle. There is a needle core (9) which can be moved axially to a limited extent in the hollow needle (5) and it is possible via this needle core (9) to vary the cross-section of or open and close the aperture (16) of the hollow needle (6) opening into the mould hollow or cavity (4). The needle core (9) bears a thickened head or plate (10) in front of the end of the aperture in the hollow needle, the outside diameter of which corresponds at least approximately to the outside diameter of the hollow needle, so that it forms, with the aperture end (6) of the hollow needle (5), a radially directed splitting valve. In relation to the hollow needle (5), the needle core (9) is axially supported by spring means (23). It is important here that these spring means (23) continuously engage with the needle core (9) in the closing direction of the aperture of the splitting valve (16) and that the needle core (9) can be moved against the spring means (23) in the opening direction by a remote-controlled driving device (17, 18).
摘要:
An extruder for the preplasticization of thermoset molding resins is disclosed. The extrusion machine includes a screw that rotates in a heated cylinder and compresses the fed-in pulverulent thermoset resinous material against a predetermined ramming pressure until it is plasticized. At the discharge end of the screw cylinder a receiving cylinder is disposed which has a hydraulic discharge piston which continuously retracts when an adjustable pressure head has been exceeded.
