Abstract: Abstract The present invention relates to an arrangement for selecting and feeding a wrapper from a storage unit to a big paper roll or the like.  The storage unit comprises several wrapper rolls of different axial length and a separate feeder for each wrapper.  The feeders are in a substantially vertical line and a guiding unit is provided for guiding the selected wrapper to a roll wrapping station.  The feeders operate as the main wrapper pulling and feeding devices of the arrangement.  The guiding unit, which is provided with a unit for transversely cutting the wrapper passing therethrough, is movable mainly vertically and can be selectively positioned in front of any of the feeders, preferably very close to them.

Abstract: Abstract The present invention relates to a method and appara-tus for determining the electrical conductivity of the ground, particularly in connection with aerial prospecting, with the use of a transmitter unit (S) and a receiver unit (M) located at a distance from said transmitter unit and particularly carried by an aircraft (21). The transmitter is arranged to generate an electromagnetic field which in-duces an electric current in the ground, and the receiver is arranged to measure magnetic and electric fields induced by said current at the measuring site, said fields represen-ting a measurement of said electrical conductivity and variations therein. The magnet field from the transmitter is transmitted horizontally as is directed transversally of an imaginary line that connects the transmitter (S) with the receiver (M). The electric field E from the transmitter is measured in the receiver in a radial direction to the transmitter. The magnetic field H is measured in a direc-tion parallel with the magnetic transmitter-field. Of the measured maqnitudes E and H the ratio E/H and/or the phase difference ? are formed, both of which are dependent on the electrical conductivity of the ground.

Abstract: RESIDUAL CLAMP ERROR COMPENSATION CIRCUIT                Abstract of the disclosure An apparatus for matching the blanking levels of two  television video  signals is disclosed.  When the vertical interval reference signal or any other signal (e.g.,  sync)  is  inserted  on  a program video signal their blanking levels should be matched. The apparatus described accomplishes this by matching the blanking level  of the  signal  being  inserted  to that of the program video.  The match is produced by sampling the residual clamping error of a slow clamp on the program channel  and adding it to the signal being inserted. Therefore,  the noise which would have been added to the  program  video  is  added to  the  inserted  signal instead  and  therefore  will  not  be  visible  in  the television picture.

Abstract: ABSTRACT OF THE DISCLOSURE A copier capable of producing simplex and duplex copies includes a tri-roll inverter that employs a ball on roll return force applicator located downstream from the tri-roll input/output members. A sheet coming into the inverter is driven by a pair of the tri-rolls into a nip formed between the ball and roll of the return force applicator. The roll which has a minimal friction force is rotated continuously in the opposite direction to the incoming sheet. When the last portion of the sheet is driven into the ball on roll nip, the friction force of the nip will cause the sheet to buckle into an output nip of the tri-roll members for outward movement.

Abstract: HEAT EXCHANGED METHODS AND APPARATUS       ABSTRACT OF THE DISCLOSURE          A vapor component of a gas mixture is separated by condensation and is recovered for further use.  A solvent vapor mixed with inert gas is condensed in a multistage heat exchange system in a manner which utilizes a first refrigerant to con-dense a portion of the vapor in a first heat exchange device, a second refrigerant, typically cold inert gas, for condensing a further portion of the vapor in a second heat exchanger and a third heat exchange device wherein the liquid phase of the inert gas (i.e. cryogenic liquid) is supplied to provide a source of refrigeration.  In this latter heat exchange device, the cryogenic liquid is introduced into a body of condensed vapor thereby chilling such condensed vapor and stirring the same to avoid freezing.  Chilled, condensed vapor is removed from the latter heat exchange device and is returned as a reflux thereto to condense the vapor component of the gaseous mixture supplied thereto.  A further portion of the chilled, condensed vapor is recirculated to the body of condensed vapor to assist the stirring of this body to avoid freezing of condensed vapor which is collected from the above heat exchange devices and is passed to a suitable storage facility.

Abstract: ABSTRACT OF THE DISCLOSURE     A throttle valve disposed within the intake bore of an internal combustion engine.  The valve thickness is large, preferably more than 1.5 mm and less than about 1/10 of the valve diameter. The full closed angle of the valve is less than 5° .  The circumferential edge of the valve has a roundness having a radius less than about five times as large as the valve thickness.  When the valve is fully closed, there is a clearance L of about 1/10,000 to 5/l,000 of the intake bore diameter between the circumferential edge of the valve and the inner surface of the intake bore.  The valve reduces the degree of air flow change at small opening angles of the valve as in the idling or low-speed operation of the engine so as to reduce the change of air flow caused by the change of the valve opening.  Thus, an optimum air-fuel ratio in a range of small opening angles of the valve can be easily maintained.
