The object of the invention is to get the concrete as well to be of good workability as also tough at same time and in addition desiderable for its several other properties, such as e.g. the unit weight and thermal capacity. In the method according to the invention as components of the concrete in variable proportions are used Portland cement or other hydraulic binders, to its particle size below ...

A new and improved auger-type ice-making apparatus preferably includes at least a pair of removable and interchangeable head assemblies adapted for preselectively producing either relatively dry flake or chip ice, cube ice or smaller nugget-sized ice pieces. A new and improved auger assembly preferably formed from a synthetic plastic material and a new and improved evaporator element are also disc...

A wind rotor member (10) comprises a central hub portion (14, 15) by which it may be mounted for rotary movement around a substantially horizontal axis, and a number of rotor blades (16) which are secured to said hub portion (14, 15) in stationary positions relatively thereto and which extend in generally radial outward directions from the hub portion. In order to enable operation within a very wi...

The cover plates extend over the part of the house facade wall in front of the frame. Support and anchoring plates (22) are fitted with at least one part connected to the outer layer (9) of the facaoe. The plates are connected to fixtures (11) in the house facade, and the cover plates are coupled to them by a connector (21). The support and anchoring plates (22) are mainly covered by the outer fac...

Method and device for watching over a sprung brake actuator with an axial revolving piston (1), affected by a spring package (2) and a fluid pressure in a chamber (6) has a sensor (3) and a master (4) for activation of the sensor. With help of the sensor (3) the condition of the brake actuator as well as the spring package (2) can be monitored. Monitoring occurs through pressure in the brake fluid...

A press for the compression of material includes a mobile pressing piston (3) in a pressing chamber (2), and a feeder passage (5), which is designed to receive the material which is to be pressed and which via a feeder opening (7) communicates with the pressing chamber; the feeder passage (5) has a section (1) with a greater cross sectional area than the feeder opening (7), and at least one closi...

The fixture (10) has a long slot (14) through which the belt extends and is linked over a surface (24) which is rounded. The surface has a variable curvature and width, over the slot length when viewed across the longitudinal direction of the slot.

The slot (12) in the cylinder (1) is closed by a sealing strip (6), and the piston has a sealing sleeve at each end. The slot has a width greater on the outside (1) of the cylinder than on the inside.

Method for handling primarily timber logs 2, in which the logs 2, as in a saw inlet, are conveyed essentially transversely to their longitudinal direction, for example by means of conveyor chains 3 running across the longitudinal direction of the logs, and one by one are transferred and fed onto a longitudinal conveyor 5, by means of which the logs 2 are individually fed, the transfer being perfor...
