Abstract: Abstract procedure for measuring, without destroying the specimen, the distribution in the thickness direction of the filler and/or coating materials of paper, cardboard or equivalent. In the procedure by radiation from a radio-isotope source is excited in the material component of the object of measurement to be examined, its characteristic x-ray radiation, the intensity of this radi-ation being observed. Measurements are made on both sides of the paper under examination and in addition the contents of other filler components are determined by x-ray absorption measurements to the purpose of eliminating the effects of these components distributing the distribution measurement.  In addition, the base weight of the paper under examination (in g/m2) is measured e.g. by beta radiation absorption measurement. The filler distriljution measurements are carried out both with the aid of measurements of the characteristic radiation of the material components excited in the paper with different radiation sources and with the aid of absorption measurements of radiation obtained directly from the source or produced with its aid in transformation targets to the purpose of eliminating the effects of theese components distributing the distribution measurements. The means carrying out the procedure comprises a measuring head       containing radiation sources and transfer mechanisms therefor, radiation transformation plates and transfer mechanisms therefor, and a radiation detector and a pre-amplifier     . The measuring head       is connected to a measuring apparatus    comprising a power source     , an amplifier   and a counter, processor and display unit.

Abstract: ABSTRACT A method and apparatus for manufacturing a film suitable for use in lamination under heat and pressure. A plurality of resins is co-extruded into concentric annuli, the inner annulus being a polyester type resin, and at least one of the outer annuli consisting of a polyolefin based resin.  The co-extrusion is carried out as the extruding die is rotated about its axis. After quenching to form a multi-layer seamless tube, the tube is collapsed and heated to a temperature suit-able for biaxial orientation.  An air bubble is intro-duced into the heated tube to expand the diameter there-of and simultaneously orient the tube biaxially by molecular orientation.  The biaxially oriented tube is cooled sufficiently to retain its molecular orientation, and is then collapsed.  The tube is then heated to a shrinking temperature while under controlled restrain to achieve a predetermined dimen-sion in amount of shrinkage in the film.  Finally, the edges of the shrunk tube are slit to form a pair of flat films.     Additional improvements are achieved by including irradiation of the films by ultraviolet light, and by treating one of the film surfaces with a corona discharge.

Abstract: ABSTRACT OF THE DISCLOSURE An improved telephone paging system and method are disclosed.  The system interfaces with a convention-al telephone branching system, such as a PBX, and remote pager devices which are worn by subscribers to the sys-tem.  A plurality of PBX extension telephone lines are connected to the system via a subscriber line inter-face, and one PBX extension line is connected to this system via a control line interface.  The subscriber line interface is used to detect ring signals on the selected extension lines.  When a ring signal has been detected on a selected line, the microprocessor-based system sends command signals to the PBX to place the incoming call on hold. The system identifies a paging code signal distinctively corresponding to the subscriber line on which the ring signal was detected.  The identi-fied paging code signal is sent to a transmitter which transmits the paging code signal to all pagers within its range.  The pager which distinctively corresponds to the paging code signal will be activated and produce a paging signal.  The subscriber may then retrieve the parked call from the PBX via any PBX extension line. To perform these functions, the subscriber to the dis-closed telephone paging system may also enable or dis-able his pager, test his pager, or directly page another subscriber via the dedicated command line.  To perform these functions, a subscriber calls the extension phone number corresponding to the command line and depresses the telephone keys which represent certain instruction in response to command signals sent by the microproces-sor.  Other embodiments of the telephone paging system are disclosed that interface with a PBX with a directed-call-pickup feature and that permit additional extension lines to be connected to the system.
