Abstract: ABSTRACT OF THE DISCLOSURE        A method for making a pressure sensitive adhesive coated laminate is disclosed   The method involves coating a sheet having a release surface thereon with a pressure sensitive adhesive to form a laminate, drying or curing the pressure sensitive adhesive and marrying the laminate to the inner surface of a facing layer   A material which produces a low zero-minute peel value in the pressure sensitive adhesive layer is intimately mixed with the pressure sensitive adhesive prior to the adhesive being coated on the release surface of the sheets the material is a polysiloxane which possesses some affinity for the pressure-sensitive adhesive and is dispersible in said pressure-sensitive adhesive material and does not sub-stantially adversely affect the adhesive ability of the pressure-sensitive adhesive  The resulting laminate can be easily applied to a substrate and removed and repositioned or straightened, if necessary, and provides an increase in peel value over a period of time to produce a more permanent installation   The laminate is suitable for use as a decorative and/or protective covering as well as for adhesive tapes, labels, and the like.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for the digestion of cellulosic fiber material providing pulp of very uniform quality.  Cellulosic fiber material entrained in treatment liquid is fed into a top portion of a first vertical treat-ment vessel, impregnation of the fiber material with treatment liquid taking place in the first vessel.  A first flow path of fiber material entrained in and impregnated with treatment liquid is established from the bottom of the first vessel to a top portion of a separate second vertical treatment vessel, liquid substantially filling the second vessel.  Liquid is withdrawn from the top portion of the second vessel (without screening) and a second flow path is established of the liquid withdrawn from the second vessel back toward the bottom portion of the first vessel, heating of the liquid during transport in the second flow path taking place.  A portion of the heated liquid flowing in the second flow path is fed into the first flow path, while the remainder of the heated liquid is fed to a bottom portion of the first vessel, the bottom portion of the first vessel serving as the heating chamber.  Washing as well as digesting may take place in the second vessel, and uniform quality digested fiber material is withdrawn from the bottom of the second vessel.

Abstract: Uniform temperature distribution in an elongated metal member, for example a steel pipe, heated by induction heating by induction heating coil means is obtained by initially preheating, for a predetermined period of time, the end portions of the elongated metal member by preliminary local induction heating means, prior to overall induction heating of the elongated metal member.  The invention avoids uneven temperature distribution in the elongated metal member resulting from the known V-shape heating phenomenon.

Title: Method of and apparatus for electrochemically  processing metallic surfaces
Inventor: FAUL WOLFGANG
IPC: C25F7/00
Filed: 1977-08-19
Granted: 1981-11-10
Abstract: Abstract of the Disclosure A method of electrochemically processing metallic surfaces of workpieces arranged in a contact-free manner with regard to the cathode and anode of an electrolytic cell by means of an electrolyte.  For the purpose of transferring an electric charge onto the workpiece surface to be pro-cessed, the electrolyte contains suspended electrically conductive bodies. These electrically conductive bodies are charged in a first chamber of the cell that contains the electrode the polarity of which determines the pro-cessing (oxidative or reductive treatment) of the workpiece surface.  A shielding diaphragm or ion exchange membrane prevents the electrically con-ductive bodies from discharging on the counter-electrode, the electrolyte being positively circulated in a circuit between the charging electrode and the workpiece to be processed.  Outside the electrolytic cell, after separation of the suspended electrically conductive bodies, electrolyte is withdrawn from the circuit, and is introduced into the second chamber of electrolytic cell that contains the counter-electrode shielded by the diaphragm.  A conveying line for the electrolyte containing the electrically conductive bodies extends between the first chamber of the electrolytic cell and the treatment chamber.  One portion of said conveying line outside the electrolytic cell comprises a porous wall which is permeable to the electro-lyte but retains the electrically conductive bodies.  An annular chamber formed between the porous wall and a surrounding outer pipe communicates with the second chamber (containing the counter-electrode) in the electrolytic cell for exchanging electrolyte.

Abstract: ABSTRACT     A fuel pumping apparatus includes an injection pump to which fuel is supplied by a low pressure supply pump. A shuttle located in a cylinder has one end connected to the injection pump and the other end to the supply pump when it is desired to feed fuel to the engine.  The move-ment of the shuttle represents the amount of fuel supplied to the injection pump and this movement is measured and the signal supplied to a processing circuit which also receives a demand signal.  The movement of the shuttle is halted by the gradual closure of communication between the one end of the cylinder and the injection pump.  This is achieved in the example by a passage moving out of registration with a port.  The rate of flow of fuel from the pump to the cylinder is controlled by a fuel control device the setting of which is determined by the proces-sing circuit which strives to ensure that the actual amount of fuel supplied to the injection pump is equal to the desired amount.

Abstract: SELF CHECKING DYNAMIC MEMORY SYSTEM Abstract of the Disclosure The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words.  Memory refresh is implemented by sequen-tially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an ex-pected total memory refresh time of approximately 1.43 milliseconds.  A particular digital word from each group of digital words refreshed is read from the memory and transmitted to a parity check circuit which generates fault signals for any digital word having faulty parity. At the end of each of the approximately 1.43 millisecond refresh cycles, the particular word read from each group refreshed is changed so that at the end of 128 full re-fresh cycles (approximately 184 milliseconds), the parity of every digital word in the memory has been checked. further, circuitry is provided to store the location of the first failing digital word in a trap register in response to an indication of faulty parity.

Abstract: ABSTRACT OF THE DISCLOSURE A fail-fixed servovalve is provided for use in a digital control system. The servovalve is comprised of a deflecting means which deflects a jet pipe in response to an electrical input signal. Fluid flowing through the jet pipe causes a spool to translate within a sleeve, thereby allowing pressurized fluid to flow through selected ports within the sleeve to control the movement of an output piston. The output of the servovalve is essentially linear over the primary range of digital input currents with the output being zero when the input current is either zero or in excess of the maximum rated current for the servovalve.
