The function of the guides is to guide the movements of raising and lowering of the alignment table (11). It is a further function of the vertical guides to support the alignment table (11) and to keep it at the desired locked working level. The solution of equipment comprises a base frame (10) in which there are detachable drive plates (C.sub.1 . . . C.sub.6), which can be lifted aside for the time of the alignment work.

Abstract: An arrangement for regulating fluid conditioning stations including a plurality of pumping devices, at least one fluid storage reservoir, at least one pressure transducer and regulating mechanism, the conditioning station providing a fluid at a certain pressure and flow for consumption. The pumping devices start and stop such that the pressure in the fluid storage reservoir or reservoirs is maintained between two limit values of pressure (the start pressure and the stop pressure). Only one pumping device is started when the pressure in the storage reservoir(s) reaches or exceeds the value of the start pressure or when the flow provided by the pumping devices in operation is less than the consumption flow. Only one pumping device is stopped when the pressure in the storage reservoir(s) reaches the value of the stop pressure or when the flow provided by the pumping devices in operation is greater than the consumption flow.

Abstract: A method for removing air from a suction roll/suction cylinder and a suction roll/suction cylinder including a roll mantle, end flanges connected to the roll mantle and axle journals for revolvingly supported the roll mantle. The mantle has numerous perforations, holes or equivalent openings passing therethrough. The suction roll/suction cylinder is connected to a suction duct that passes onto the interior of the roll/cylinder and transfers a vacuum force therein. Air is drawn or sucked through the perforations into the interior of the roll mantle so as to press a paper web toward an outer face of the roll mantle. The suction roll/suction cylinder has a system of suction pipes connected with the suction duct and including at least one suction pipe into which air is guided and/or sucked from the vicinity of the inner face of the roll mantle of the roll/cylinder.

Abstract: A hose capable of exhibiting increased flexibility and lubricity. The hose is made of soft synthetic resin containing a slidability providing silicone resin material. In particular, the slidability providing silicone resin material contained in a surface layer of the hose or ribs formed on a surface of the hose. In production of the hose, re-dispersion of the resin material and forcing of layers of the hose against each other are carried out. Alternatively, a layer containing the resin material and a layer free of the resin material are co-extruded.

Abstract: A device for alignment of a vehicle body and a method in the work of alignment of a vehicle body. The device includes an alignment table to which the vehicle is attached by skirt clamps, the vehicle being fixed from skirt plates to the skirt clamps and through the skirt clamps to the alignment table during alignment work. Each skirt clamp has a support arm which is positionable in relation to, and separated from, the skirt clamp and which support arm can be coupled with the skirt clamp by a fastening member. The support arm is also connected with the constructions of the vehicle directly or through intermediate parts such that damage to the skirt beam is prevented by the support arm during the alignment work as the support force of the support arm is received by the skirt clamps.

Abstract: A method in a paper machine or in a finishing device of a paper machine for collecting and removing dust and other particulate material separated from or in the vicinity of a web. Air that contains the dust is transferred by air blowings, specifically, a first air flow is directed from a first blow nozzle to flow in the cross direction of the machine from the tending side of the machine to the driving side. This first air flow carries the dust separated from the web or equivalent along with it. The dust-laden air flow is turned downwards by a second air flow being directed from a second blow nozzle to be drawn into a suction box.

The device interacts with a smooth rod (1) and comprises an intermediate socket in the shape of a split ring (22) engageable on said rod. A tightening means (23) is arranged on the ring (22) at the split therein so that when it is tightened, the rod (1) protrudes from the ring while engaging the bottom of a U-shaped body to which the member is secured, whereas the free ends of the ring flanges (221, 222) engage both the rod (1) and the body (21). The device is useful in the field of orthopaedic equipment fitted during spinal surgery.

Abstract: A modular plug and multi-pair cable assembly provides reduced near-end crosstalk between two signal pairs of the cable. A modular plug has a plurality of wire-receiving passages disposed in first and second planar arrays spaced one above the other, with the passages of one planar array being staggered in position with respect to the passages of the other planar array. An end of a first wire of each of two signal pairs is received in respective wire-receiving passages of the first planar array and an end of a second wire of the two signal pairs is received in respective wire-receiving passages of the second planar array. A first pair plane in which the wire ends of the first signal pair are situated intersects a second pair plane in which the wire ends of the second signal pair are situated. In this manner crosstalk between the two signal pairs resulting from magnetic and electric field coupling is reduced.
