Abstract: A b s t r a c t _______________ An adhesive, particularly for use in the making of corrugated cardboard, consists of starch, water and al-kali in such proportions that the mixture contains 10 to 40% by weight of starch solids and has a pH value of 8 to 13, a gel point of 52 to 75°C and a Stein-Hall viscosity of 20 to 120 seconds. The starch consists of completely ge-latinized starch and partly swollen starch in a weight ratio  between 0.2:100 and 2:1, which results in a greatly increased gelatinization rate and thereby in-creased wet tack of the adhesive, and this in turn per-mits greater machine rates in the making of corrugated cardboard.            The adhesive may be produced by first maintaining a mix-ture of ungelatinized starch and water at 20 to 100°C, preferably in the presence of an acid or a base, until th starch is completely gelatinized, then adding more ungela-tinized starch and optionally water, adjusting pH to be-tween 8 and 13 and maintaining the mixture at 20 to 75°C until it has reached a Stein-Hall-viscosity between 25 and 130 seconds, followed by the addition of a reaction in-hibitor, preferably borax, alum, another acid material, cold water or ice, in an amount such that the gel point of the mixture will be between 52 and 75°C. The initial com-plete gelatinization of ungelatinized starch may optionally be replaced by an addition of completely gelatinized starch powder.               .

Abstract: An Apparatus for and Method of Coupling Shafts Abstract An apparatus is provided for transferring torque from one shaft to another.  The shafts (11) and (12) are coupled together using a flexible member, such as an elastomeric spring or belt (23), trained around pins (21) eccentrically mounted on at least two planet gears (19).  A sun gear (15) which is connected to one of the shafts (11) meshes with the planet gears.  These gears (19) are also connected to the other shaft (12), either through a ring gear (66) or pivots (27).  When one of the shafts is rotated, this causes the planet gears (19) to rotate, and this rotation moves the pins (21) in an arc.  This gradual controlled movement of the pins (21) causes the belt (23) to stretch in a manner so that as torque is transferred from one shaft to the other, troublesome torsional vibrations are effectively damped.        This energy-absorbing, torque cushioning apparatus is particularly suited for use as a lock-up clutch in motor vehicles.

Abstract: IMPROVED ROOM TEMPERATURE VULCANIZABLE SILICONE   RUBBER COMPOSITIONS AND PROCESS OF MAKING               ABSTRACT OF THE DISCLOSURE    A one-component room temperature vulcanizable silicone rubber composition having improved flow characteristics and a process for preparing cured silicone rubbers derived therefrom.  The one-component silicone rubber compositions consist of a silanol end-stopped linear diprganopolysiloxane base polymer, a filler, and organo-triacyloxysilane cross-linker, a catalyst and an organo-polysiloxane copolymer consisting of a polysiloxane chain and a polyether chain which are linked together through various carboxyl alkyl radicals.  This final component accounts for the improvement in the flow properties of the one-component silicone rubber compositions.  In a process for preparing a cured one-component silicone rubber composition, the polysiloxane polyether copolymer is mixed with the diorganopolysilioxane base polymer after which the cross-linker is added and the final mixture is exposed to moisture for curing.  A typical use of such a one-component is in caulking and sealing applications, where strong adhesion to various surfaces is important.

Abstract: 49                  47,870 ABSTRACT OF THE DISCLOSURE     The redundant signals from the sensor assemblies measuring  the  process parameters  of  a nuclear reactor power supply are transmitted each in its turn to a protec-tion  system  which  operates  to  actuate  the  protection apparatus for signals indicating off-process conditions. Each sensor assembly includes a number of like sensors measuring the same parameters.  The protection system has a number of separate protection units, each unit receiving the process signals from the like sensors of each assembly in its turn.  The sets of process signals derived from the sensor parameter assemblies are each in its turn trans-mitted from the protection system to the control system which impresses control  signals  on the  reactor or  its components to counteract the tendency for conditions to drift off-normal status requiring operation of the protec-tion system.  A parameter signal selector is interposed between the protection  system and  the  control  system. This  selector prevents  a parameter signal of a set of signals, which differs from the other parameter signals of the set by more than twice the allowable variation of the sensors which produce the set, from passing to the control system.  The connection between the protection units and the selector is four separate fiber optic channels so that electrical interaction between the protection units and the selector or control system is precluded.          The selectors include a pair of signal selection units, one unit sending selected process signals to pri-47,870 mary  control  channels  and  the  other  sending  selected process signals to back-up control channels.  Test signals are periodically impressed on a selected pair of a se-lected unit and control channels.  When test signals are so impressed the selected control channel is disabled from transmitting control  signals  to the reactor and/or its associated components.

Abstract: ABSTRACT OF DISCLOSURE   By enzymatically modifying vegetable glycoprotein isolates with an acid proteinase such as pepsin, the glycoproteins may be converted to a vegetable isolate useful as egg albumin replacement or whip-stabilizing agent.  The enzymatic modification partially hydrolyzes the glycoproteins and compositionally alters the glycoprotein subunit and aggregate structure.          The enzymatic alteration produces a glycoprotein aggregate comprised of a plurality of subunits having saliently different physical and functional properties from that of the vegetable protein precursor source materials. The enzymatically modified vegetable isolates are capable of forming firm, white, opaque heat-set gels similar to those of egg albumin.  The enzymatically modified glycoproteins are compatible with salt-containing recipes and functionally useful over a broad pH range.

Abstract: ABSTRACT OF THE DISCLOSURE     A power press arrangement including one or more workpiece handling mechanisms such as loaders, unloaders, turnover devices, conveyors, etc.  The various workpiece handling mechanisms are controlled in synchronism with the press or presses through numerical control systems which are coordinated with press slide positions.  For each axis of controlled movement, a discrete number of desired posi-tion locations are loaded into an associated press control memory, and the data is processed into a derived motion table for each axis and followed to effect axis motion in coordination with press slide position.  During operation of the press, the associated control system continuously derives motion control parameters for the controlled axes based upon the tabular values.  The actual position of each controlled mechanism is also monitored and compared with the desired position at repetitive time increments to detect any position errors.  A desired velocity for each controlled mechanism is also derived from the desired position signals, and the mechanism is driven at a veloc-ity which is a function of both the desired velocity and any position error.

Abstract: MEMORY PROTECTION CIRCUIT FOR AN ELECTRONIC POSTAGE METER              Abstract of the Disclosure An electronic postage meter includes a nonvolstile memory pro-tection circuit.  The memory protection circuit prevents the inadvertent writing of spurious data into memory locations in the nonvolatile memory during a power down cycle.  The memory protection circuit works in conjection with a WRITE voltage terminal associated with the nonvolatile memory.          Means couple a first voltage source providing a predetermined polarity voltage to the WRITE voltage terminal when a preclntermined power condition exists such that the nonvolatile memory is enabled to have data written into memory locations.          When the predetermined power condition does not exist, the means utilize a second different voltage source to change the voltage level at the WRITE voltage terminal to insure that data is not written into the memory locations.

Abstract: MULTIPLE PULSE TEA LASER  Abstract A laser system capable of producing multiple pulses comprising a single optical resonator having multiple dis-change regions and multiple sets of electrodes and preion-izers.  The optical resonator is folded and the beam passes through all of the discharge regions.  Since the multiple discharges occur within the same resonator, multiple ident-ical pulses are produced and since the discharge regions are separated, the shock wave and medium inhomogeneity produced by a  discharge in one discharge region will not disturb the others.  The overall mirror separation and electrode spacing define a Fresnel number suited for single transverse mode operation.
