Title: Connector keying arrangement
Inventor: KATO MATSUO
IPC: H01R13/645

Abstract: CONNECTOR KEYING DEVICE                           ABSTRACT This invention relates to the field of electri-cal connectors, and particularly concerns electrical connectors with multiple contacts requiring keying of the mating connector parts.  With prior art devices, when more than one connector pair is used in a system, different connector parts must be chosen which have a different keying configuration for the key and groove. With another prior art device, which uses a single type connector part, it is necessary to sacrifice one contact position in the connectors.  The present invention over-comes the deficiencies of the prior art noted above by providing a keying device whichpermits manufacture and production of  a single type of male or female connector part and yet does not require the sacrifice of contact positions within the connector parts to effectuate the keying.  The invention therefore provides an improved connector keying device for keying mating first and second connector parts to assure proper connection between the parts and to prevent connection to other connector parts of unlike keying.  In accordance with the invention, there is provided a key mount affixed to the first connector part and adapted to receive a key member mounted thereto.  An appropriate key member is removably attached to the key mount.  A key member receiver is mounted on the second connector part and has a key member-receiving slot therein aligned with and slidingly receiving the key member when the first and second connector parts are mated.

Abstract: FORAGE HARVESTER FEED ROLL MOUNTING MECHANISM           ABSTRACT OF THE DISCLOSURE In a forage harvester having a rotatable cutterhead and adjacently-positioned shearbar, an upper feed roll assembly comprising at least one upper feed roll mounted above and forwardly of the shearbar for movement by a pair of arms.  A lower feed assembly cooperates with the upper feed roll assembly to convey crop material to the cutterhead across the shearbar.  A tensioning assembly is coupled to the mounting arms for the upper feed roll. First and second positions of the tensioning assembly provide a first condition in which the upper feed roll assembly is biased toward a lower operative position adjacent the cutterhead and shearbar and a second condition in which the bias on the upper feed roll assembly is relaxed, permitting movement to an upper inoperative position generally remote from the cutterhead and shearbar to thereby expose and render the shearbar readily accessible for servicing.  A torque shaft is utilized to maintain the upper feed roll in a non-askew relationship by applying force via the tensioning assembly to the upper feed roll assembly in its operative position.

Abstract: MULTIPLE TRUCK FREIGHT CAR HANDBRAKE ARRANGEMENT FOR A RAILWAY CAR ASSEMBLY  COMPOSED OF A SERIES OF ARTICULATELY INTERCONNECTED CARS (CASE CWU/15825 Abstract of the Disclosure A handbrake arrangement for railroad freight cars is disclosed that will connect a mechanical hand-brake operating mechanism to the brake equipment (brake beams and brake shoes) on 2, 3, or more trucks on the same freight car.  It is especially useful on articu-lated freight cars consisting of multiple units in order to satisfy handbrake power requirements required by industry and Federal regulations, but a similar arrangement may be used on special purpose cars having a multiplicity of trucks.  On an articulated car, consisting of a number of units, there is a multiplicity of trucks and because of the size and weight characteris-tics of the car, it is desirable to connect the hand-brake mechanism to a number of the trucks in order to provide adequate handbrake power.  A relatively simple mechanical handbrake mechanism for providing adequate braking power to a series of lightweight short articu-lated interconnected cars (of the kind disclosed in Adams et al (U.S. Patent No. 4,233,909 issued November 18, 1980) consists of a series of rods, levers, and slack adjusters interconnecting two or more trucks to the handbrake operating mechanism.

Abstract: Abstract A circuit for controlling the voltage of a network which supplies electrical power to a load having a rapidly varying impedance.  The circuit contains a pair of controlled electric valves which are connected in parallel between two conductors of the network and poled for condition in opposite directions.  A voltage transformer produces a signal corresponding to the network voltage, which signal is conducted to an integrator and subsequently compared to a preset mean value.  The preset mean value corresponds to a desired amplitude at which the positive and negative half-wave cycles of the network voltage are desired to be maintained.  In one embodiment, the controlled electric valves are caused to conduct current during respective half-waves of network voltage so as to maintain the amplitudes of the half-waves at the preset mean value.  Other features are described for compensating for long term drift of the network voltage and for controlling the controlled electric valves by means of logic circuitry.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement in a radiation boiler for cooling a gas stream con-taining solid and molten particles of the type comprising an inlet for introducing the gas vertically at the top of said radiation boiler, a water bath disposed at the bottom of the radiation boiler for removing the particles after they have been solidified and cooled is disclosed. The improvement resides in the fact that there is disposed between the gas inlet and the water bath, at least two concentrically arranged heat exchange elements, the through passage of the inner heat exchange element being in a fluid flow registry with the feed means.  A conical deflector is disposed in registry with the flow of gas passing through annular passage which deflector is disposed at the bottom on the radiation boiler above the water bath, but is at least partially below the lower edge of the vertical wall of the inner heat exchange element. This causes gas which strikes the conical deflector to pass upwardly both in the through passage and in the annular passage between the inner and outer heat exchange elements.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved process is provided herein for producing a propyl-ene-ethylene block copolymer by subjecting propylene and ethylene to three-step polymerization using a stereoregular polymerization catalyst. In the first step propylene alone or a propylene/ethylene mixture is poly-merized so that the average ethylene/propylene reaction ratio is 6/94 or less, thereby polymerizing 60 to 95% by weight of the total polymerization amount.  In the second step, a propylene/ethylene mixture is polymerized so that the average ethylene/propylene reaction ratio is 25/75 to 67/33, thereby polymerizing 1 to 20 % by weight of the total polymerization amount.  In the third step a propylene/ethylene mixture is polymerized so that the average ethylene/propylene reaction ratio is 76/24 to 89/11, thereby polymerizing 4 to 35 % by weight of the total polymerization amount.  In the second and third steps, ethylene alone is supplied, there-by gradually decreasing the amount of  propylene in the polymerization system from the first step to the succeeding steps.  The polymer ob-tained thereby has markedly well balances physical and optical properties e.g. impact resistance, stiffness, transparency and impact blushing.

Abstract: ABSTRACT       Multifrequency                          February 9, 1981 The  prior  art  of multifrequency  eddy  current  instruments  has required  a band pass filter to separate each individual frequency.  The drawback of the above mentioned method is the requirement to change  the bandpass  filter if the inspection frequency is changed.  This invention relates  to  a  design that eliminates the requirement  for  a  bandpass filter.  The  aggregate of inspection frequencies are applied to  linear multipliers  which  shift  the information from one  of  the  inspection frequencies  to a base band signal.  The information is  then  separated from the signals of other frequencies with a low pass filter. The advan-tage  is  that  an inspection frequency may be changed by  changing  the oscillator frequency only.
