Abstract: A narrow guide belt runs in the edge area of the paper web width across the drying cylinder of a paper machine and serves to thread the transfer strip through the drying cylinder section. On each drying cylinder, about in the center of the looping zone formed by the guide belt on the drying cylinder, two or three guide belt pulleys are so arranged that the belt will for a short distance lift off the cylinder. The pulleys can be swiveled in a position spaced from the drying cylinder where the guide belt lifts entirely off the cylinder.

Abstract: A vehicle measuring instrument to measure a position-deviation of any selected vehicle reference point as when a person such as a car mechanic performs repair and maintenance of a car. With the well known vehicle measuring instrument of such type, an error caused by a deviation of the perpendicularity indicated by a pendulum member from the vertical direction of the vehicle due to an inclination of this vehicle has been detected and then a troublesome sequence of operations have been performed to compensate such error. According to the present invention, there is provided an angle variable portion by which an angle of each suspender with respect to a base frame can vary under an effect of this base frame's own weight in response to an inclination of the vehicle so that a reference portion is automatically displaced so as to respond to the deviation of the pendulum member and thereby to compensate said error automatically.

Abstract: A heatable roll has a plurality of annular, preferably electrical, heating elements (13) distributed internally along the length of the roll body (10,11). A slip-ring arrangement (22) rotating with the roll connects the heating elements with a heating current source (20) located outside the roll. A heating output setting device (9) arranged inside the roll is provided for each heating element and is connected to a signal transmitting arrangement (31 to 34). A control signal is formed for each heating element in a control center (21) located outside the roll, and is supplied to a parallel-serial converter (31). This converter forms one serial signal sequence from the plurality of parallel control signals, and this sequence is supplied, for example by means of slip-rings (22a), to a serial-parallel converter (34) located in the roll. This converter converts the serial signal sequence back again into parallel control signals which are supplied to the individual heating output setting devices.

Abstract: Plant material (for example, milled hop pellets) is placed in a pressure vessel and carbon dioxide is passed through the vessel in order to extract essential oil and resin components. Said passage is stopped after a predetermined period of time and inert gas(es) is/are used to displace said carbon dioxide and the extract(s) from said vessel to another location.If liquid carbon dioxide is used, it is displaced to an evaporator in which the extract is deposited, carbon dioxide being gasified. If supercritical carbon dioxide is used, it is displaced to a separator.Alternatively, the plant material may be steeped in liquid carbon dioxide which, after the steeping period, is displaced as aforesaid.The gases (carbon dioxide and inert) may be vented to atmosphere or recovered for re-use.Extraction using liquid carbon dioxide is isobaric whereas using supercritical carbon dioxide, the pressure in the pressure vessel is higher than in the separator.
