Abstract: ELECTRONIC LOCK SYSTEM Abstract An electronic lock system having a data encryption key physically and electronically protected from identification for protecting electronic equipment from use by unauthorized personnel.  The lock system includes two keys circuits that implement an encryption key and algorithm for encrypting random data.  The encryption key and algorithm are physically protected from physical identification by encapsulating the implementation in an integrated circuit.  The second key circuit identical to the first is included in a lock circuit for generating two output signals.  One output signal represents an unlocked condition of the system, whereas the other represents the lock condition.  A random data signal is applied to the two key circuits for encryption under the encryption key and algorithm.          The lock circuit further includes a match circuit which generates the unlocked condition output signal when the encrypted data from the two key circuits matches for a predetermined period of time.  Otherwise, the match circuit generates the locked condition output signal.

Abstract: ABSTRACT A method and apparatus for determining the oxygen uptake rate of bacteria in a body of liquid incorporates withdrawing a sample of the liquid into a chamber where a dissolved oxygen probe is located, the probe outputting a signal which is a function of the amount of dissolved oxygen in the sample.  The sample is aerated, and a computer is used to sample the signal at regular intervals to produce a series of time-separated values corresponding to the sampled signals, the values representing the dissolved oxygen in the sample at the timed intervals.  Repeated samples can be taken, so that the O.U.R. can be monitored on a continuing basis.  The O.U.R. information can be used to control the rate of aeration in a tank, or to control the rate of recycling of activated sludge from the downstream to the upstream end of the tank.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a multiple function control stalk for a vehicle having a linearly moveable wiper delay rheostat.  The control stalk includes a plurality of switches for controlling various devices on the vehicle, such as the windshield wiper and washer controls and vehicle speed or cruise controls.  A windshield wiper delay switch is provided on the control stalk which includes a rheostat having an arm which is linearly moveable in a direction generally parallel to the longitudinal axis of the control stalk.  The wiper delay rheostat is disposed slightly above the body of the control stalk for easy viewing and manipulation by the vehicle driver.  Movement of the arm of the wiper delay rheostat varies the electrical resistance thereof and, consequently, causes an electrical control circuit to alter the period of delay between successive cycles of operation of the windshield wipers.

Abstract: BALL JOINT            Abstract of the Disclosure A ball joint of the type having a ball stud and preformed plastic socket includes means for sealing the stud head receiving socket opening and assuring the maintenance of the seal in spite of accumulated tolerance variations.  A cap with an inwardly converging peripheral closure surface fits within and conforms closely to a matching closure surface in the socket opening. Deformable protuberances on the outer side of the cap are engaged and deformed by a surface of the suspension control arm to which the socket is mounted, or by a surface of a cover which fixes the socket to the control arm.  The protuberances extend far enough from the cap outer side to assure that engagement and deformation in spite of accumulated tolerance variations in the components of the ball joint.  The deformation forces the cap into the socket opening as the ball joint is completed to engage the closure surfaces more tightly and assure maintenance of the seal of the socket opening.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for severing successive lengths of tubing in a die set in which the movement of an upper die shoe is translated by mechanism to clamp the tubing on a lower die shoe, move a notching blade across the clamped tubing to slot the tubing, and pass a cutoff blade through the slot to sever the tubing. Use of a lever arm pivoted to one of the die shoes in combination with a cam on the other die shoe optimizes horizontal movement of the notching blade relative to vertical movement of the die shoes.  In a preferred form, the cutoff blade is passed through a slot in the notching blade holder.  The die set can be used in apparatus where the tubing is intermittently supplied, or, as in a tabling mill, a continuous length of tubing is moved during the severing process.

Abstract: ABSTRACT OF THE DISCLOSURE A METHOD FOR INCREASING THE EFFICIENCY      OF A CAUSTICIZING PROCESS A method for increasing the efficiency of the causticizing process which comprises: a) adding to a green liquor between 78 and 82% of the stoichiometric amount of lime necessary to react with the amount of Na2C03 present in the green liquor to obtain a white liquor containing NaOH and lime mud.  The white liquor is then clarified by extracting the lime mud present to obtain a white liquor having a total solid concentration of about 10-60 grams/liter.  The supernatant liquid of the white liquor is treated with an additional amount of lime to increase the causticity to about 87%, then allowing further causticizing reaction between the lime and Na2CO3.  The remaining lime mud present is removed to obtain a white liquor which has the causticity of about 87%.  One is thus able to raise the causticity of partially clarified white liquor following the normal causticizing process, the mud present being sufficient to increase causticity without substantially decreasing settling rate.

Inventor: TEGLUND LARS
IPC: E03F7/00

Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.
