Abstract: The invention concerns rolling techniques, especially a roll unit intended for use in a roll housing, containing grooved rolls 2, 3. The stop collar 8 of each roll 2, 3, which is formed at the shaft journal of the roll 2, 3, is arranged in a hydrostatic pressure bearing 12, which is arranged in a bearing housing 14 secured to a frame 1. Each bearing 12 is provided with disks 15, 16, while a single disk is arranged at both end surfaces of each collar 8 parallel with its end surfaces. The disks 15, 16 are arranged to form, together with the bearing housing 14, a cavity which communicates with a liquid source via a hole 19 situated in the bearing housing 14. Each stop collar 8 contains a ring-shaped channel 30, which is axial with the corresponding roll 2, 3. The channel 30 contains two washers 25, 26, which are secured to the bearing housing 14 parallel with each other and separated from each other by a certain distance. The hole 19 in the bearing housing 14 is arranged so that the liquid flows between the washers 25, 26. The liquid source is configured so that one can regulate its capacity depending on the displacement of the rolls 2, 3. The roll unit proposed according to the invention makes it possible to directly regulate the mutual position of the rolls 2, 3 during the course of the rolling. <IMAGE>

Abstract: A method of forming a heat-sealable carton having a pair of mating surfaces to be sealed includes the steps of coating at least one of the carton surfaces with a heat-activated thermosetting adhesive, spraying a fine mist of a water-based adhesive which exhibits high contact tackiness when dry, to form a discontinuous film on the coated surface, heating the water-based adhesive coated surface to a temperature sufficient to dry the water-based adhesive and activate the thermosetting adhesive, placing the mating carton surfaces in contact with each other and applying pressure for a time sufficient to seal the contacting surfaces together. A carton formed by the method is provided with flaps sealed by the combination of thermosetting heat-activated adhesive and high tack water-based adhesive. This allows the mating surfaces to be rapidly sealed by automatic carton closing apparatus and results in a sealed carton which exhibits good seal integrity at high temperatures. A carton formed in this manner is useful, for example, as a food container which can be placed directly in an oven to heat the contents thereof, with the carton seal being unaffected by the oven heat.

Abstract: To limit the line current dissipation in a telephone system it is considered desirable, especially in electronic systems, for the line current feed to be constant current. In the present arrangement the constant current supplied to the line is made adjustable in accordance with line conditions, especially the voltage between the line wires. A high impedance monitor is connected across the line to monitor the voltage between the two wires and to produce therefrom a reference voltage which is applied to the constant current generator so as to cause it to generate a current for line feed whose value is determined by the line voltage.

Abstract: The invention relates to a method for connecting two concrete parts 16, 18 to one another, and a sealing arrangement 2, 4 for use when carrying out this method. According to the invention, the first concrete part 16 is cast first, and the second concrete part 18 is cast after the first concrete part has hardened, the second concrete part being cast bearing against the first concrete part within a joint area. To seal the joint between the concrete parts, a first portion 2 of a sealing element made of elastic material is cast into the first concrete part 16 when the latter is being cast, and a second portion 4 of the sealing element projecting from the first concrete part 16 is cast into the second concrete part 18 when the latter is being cast. The sealing element 2, 4 thus extends in the joint area between the concrete parts in order to bridge the joint between these. <IMAGE>

Abstract: A continuous casting apparatus in which a multi-plate continuous casting mold is provided with an electromagnetic inductor for imparting rotary motion to the molten metal within the mold. Each plate is provided with a cooling chamber on its side turned away from the molten metal and an inductor is disposed around the mold so that the poles of the inductor approach the cooling chambers and are formed with passages through which threaded bolts can pass to serve as demountable support elements whereby the inductor is affixed to the chambers and by the latter to the mold. The passages run parallel to the planes of the sheets forming the laminated inductor. The withdrawal of the bolts permits separation of the inductor from the cooling chambers and thus separation of the plates so that grinding and removal of shims can compensate for the wear of the cavity-defining surfaces.

Abstract: The invention relates to a device at a rotator and grapple unit intended for tree handling and suspended at the end of a boom. The rotator (8) and grapple (11) are connected each to a pair of flexible operating lines (6,7 and, respectively, 9,10) from a hydraulic pump (1) via a control valve (3). For rendering possible completion of the unit with a hydraulic sawing device without adding two additional hydraulic hoses for this purpose, which would give rise to problems due to the combined bending and rotary movement at the crane tip and resulting heavily increased strains and wear on a bundle consisting of six hoses, according to the invention a branch line (13) is taken from the operating line (10) used for closing the grapple (11), which branch line is located in a place after the rotator (8). The branch line (13) extends to a hydraulic sawing device (15,16) via a pressure-sensing valve (14). This valve is opened when the operator after completed gripping function adjusts the hydraulic pump (1 ) to a higher pressure level in order thereby to drive the sawing device from the operating line (10). When the sawing is completed, the operator resets the pump to the original pressure level, and the return flow from the sawing device passes out through return lines (22,25) and the second operating line (9) of the grapple (11). The unit is thereby ready for a new setting, gripping and sawing operation.

Abstract: The speed monitoring component comprises a hydraulic pump which is driven at a speed which is at all times in constant proportion to the water turbine speed, and the oil pumped by it flows through a throttle. Oil, the pressure of which is speed-dependent, activates a component for distributing oil to a work cylinder, and is fed from a separate pressure system which is independent of the measurement oil system. A low filter can be used for speed stabilisation, and a part of the functions in the system can be electrical. - The water turbine receives water from a pipe or a sump, and the quantity is regulated by a valve. The turbine drives a generator or other machine, the speed of which requires to be maintained at a constant level. The oil in the measurement system flows through the throttle and back to the measurement suction point, and in the conduit a pressure is produced which is quadratically dependent upon speed. Pressure controls an oil feed regulator to the hydraulic cylinder, which increases or reduces water feed to the turbine. (Provisional Basic advised week 85/29)(0/1)
