Abstract: Abstract S u m m a r y:         Method and Device for Controlling the Distribution of Brake Force With a view to controlling the distribution of brake force onto the front axle and the rear axle of an automotive vehicle in dependence upon the static and dynamic axle load distribution as well as other measured variables, sensors (2 through 4, 16 through 19) serve to ascertain the wheels' ro-tational behaviour at the front axle (VR) and at the rear axle (HR) as well as, if necessary, the translational decel-eration of the vehicle, and, by these data, there will be determined the brake slip ( .lambda. ) at the front and at the rear wheels or measured values that are proportional to the brake slip, respectively.  After the electronic combination and processing of these signals, the brake force distribution will be controlled in dependence upon the brake slip such that the coefficient of friction (fHR) at the rear wheels amounts to about 80 through 100 %, preferably 85 through 97 %, of the coefficient of friction (fVR) at the front wheels.     The braking pressure build-up at the rear wheels is gov-erned preferably with electromagnetic switching valves (6, 13), the time-responsive pressure increment occurring step-wise.          Figure 1

Abstract: Abstract of the Disclosure An improved glandless plug valve of the type in which a tapered plug fits into a tapered bore in a valve body is provided wherein the tapers formed on the plug and in the body coact to form a body seal.  A stem seal is also provided.          The stem seal comprises a ring-like sealing member confined within mating grooves in the top of the plug and in a floating seal member.  The floating seal member is biased downwardly to effect the seal between itself and the ring-like seal member.          The bias force is transmitted to the plug valve urging it into engagement with the body of the valve, to provide a good body seal.  In a preferred embodiment, the valve and plug are lined such that the valve is suitable for use in connection with corrosive liquids or slurries.  The floating seal provides automatic compensation for temperature induced dimensional changes and for wear.

Abstract: 51,233 ABSTRACT OF THE DISCLOSURE A speed switch for  an elevator  system  which obtains its information from distance pulses generated in response to car travel.  The reference speed setting of the  switch is  a  function of the desired predetermined speed at which the switch is to operate,  the number of distance pulses produced per inch of car travel, and the time required by a counter to count to a predetermined value.  This arrangement facilitates the selection of the reference speed setting of the speed switch,  such as by using  a  thumb  switch.   An emergency terminal  stopping arrangement using the speed switch is also disclosed,  as is a new and improved elevator system in which the normal slow-down  speed  pattern  and  emergency  terminal  stop functions are both responsive to distance pulses produced in response to car movement, enabling a terminal slow-down speed pattern to be initiated by circuitry independent of the distance pulses, such as via a notched terminal slow-down blade adjacent to each terminal floor.

Abstract: ABSTRACT OF THE DISCLOSURE          There is provided a digital multiplying circuit in a parallel multiplying circuit which can multiply an input which changes at a high data rate by the pipeline processing.  A multiplicand is inputted to this circuit.  Partial product signal generating circuits of the number corresponding to only the number of partial product signals which are needed are provided.   The partial product signal generating circuits produce the partial product signals in accordance with the state of predetermined bits of a multiplier.  Each partial product signal is added, thereby obtaining a multiplication output of the multiplicand.  The pipeline processing  is performed in the adding operation of each partial product signal.  The multiplier and multiplicand are delayed.  The predetermined partial product signal generating circuits are arranged immediately before the adders which need the partial product signals, thereby obtaining the partial product.          With this digital multiplying circuit, the total number of bits of registers is reduced and the circuit scale is made small.

Abstract: IMPROVED DOCKBOARD CONSTRUCTION   Abstract of the Disclosure A pit-mounted dockboard which eliminates the need for a conventional sub-frame and has an improved mechanism for retracting the cross traffic legs when the ramp is moved to a downwardly inclined below dock level position.  The dockboard includes a ramp hinged to the supporting structure and movable from a horiz-ontal cross traffic position to an upwardly inclined position and to a downwardly inclined below dock level position. A pair of cross traffic legs are pivoted to the forward portion of the ramp and are movable between an upright supporting position and a rearwardly pivoted retracted position.  The cross traffic legs when in the supporting position engage the bottom of the pit in the loading dock to support the ramp in the cross traffic position.  Locking means are engageable with the cross traffic legs to prevent the cross traffic legs from being pivoted to the retracted position when the ramp is in the cross traffic position.  A gas spring assemb-ly interconnects the cross traffic legs and an arm connected to the ramp to provide a toggle mechanism. The toggle mechanism can be manually moved to an over-center position to load the gas spring, so that when the ramp is pivoted upwardly, the force of the gas spring assembly will move the cross traffic legs to the retracted position, so that the ramp can then be lowered to the downwardly inclined position.  When the ramp reaches the downwardly inclined position, the toggle mechanism is automatically returned to the undercenter position so that the cross traffic legs can be returned to the upright supporting position on elevation of the ramp.  An improved telescopic main-tencance strut assembly is incorporated with the dockboard to hold the dockboard at an upwardly inclined position for maintenance.

Abstract: Abstract of the Disclosure A method for substituting one amino acid for another in a protein chain to improve selected properties of the protein.  Initially, an mRNA molecule capable of producing an unmodified protein of the type it is desired to modify is provided.  Next the codon along the mRNA chain which ordinarily accepts the anti-codon corresponding to a first amino acid which is to be replaced with a selected second amino acid is determined.  The tRNA which ordinarily brings the first amino acid to that site is modified to carry the second amino acid instead.  The modified protein is then formed by translation techniques in the presence of the modified  tRNA,  whereby  the  second  amino  acid  is incorporated in the protein chain in place of the first amino acid.   Several methods of accomplishing the modification of the selected tRNA are also disclosed.

Abstract: ABSTRACT          In the attachment of an appliance's electrical supply cord to an ordinary electrical outlet on a wall, it is common to have a plug encasing the cord such that the cord adjacent to the plug will be parallel to the wall when the plug is inserted into the outlet, permitting furniture or other objects in front of the outlet to be set closer to the wall.  In this invention, the protusion of the plug from the outlet is reduced to the width of the electrical cord itself.  The invention will be of great value in allowing the cord to lie substantially flat against a wall even at its juncture with the plug and in allowing furniture or other objects to be set approximately a mere width of the cord away from the electrical outlet surface.
