Abstract: HITCH CONTROL SYSTEM                    Abstract of the Disclosure A hitch control system includes various sensors, an operator command lever,  a spring-centered three position raise/lower switch, a control unit which generates control signals as a function thereof and an actuator which moves the hitch in response to the control signals.  The control system permits the operator to move the hitch to a working position via manipulation of the command lever and a single manipulation of the raise/lower switch.  The control system ignores switch manipulation unless the manipulation persists for at least a certain time period, or if the switch is manipulated in a different manner within a certain time of the earlier manipulation.  In a failure mode the control system permits the hitch to be moved to a working position via manipulation of the raise/lower switch when the command lever cannot be so used.

Abstract: STERILIZATION BIOLOGICAL TEST PACK             ABSTRACT OF THE DISCLOSURE              A   sterilization   biological   test   pack comprises a first plurality of apertured planar sheets of  substantially  porous  paper  disposed  to  form  a stack.    Each  of  the  sheets  defines  a  generally centrally disposed aperture,  the apertures operatively defining together a single cavity extending through the stack.   Second  and  third  pluralities  of  unapertured planar  sheets  of  substantially  porous  paper  are disposed  on opposed  sides  of  the  stack  and  aligned therewith  to  close  the  stack  cavity  at  either  end thereof  and  define  a  chamber  about   the  cavity configured  and  dimensioned  to  receive  a  biological indicator.  Fourth and fifth pluralities of unapertured planar  sheets  of  paper  of  intermediate porosity are disposed  on  exposed  sides  of  the  third  and  fourth pluralities,  respectively,  and  aligned  therewith.   A sheet  of  unapertured paper  of a low but appreciable porosity  is  disposed  as  an  overwrap  all  about  the periphery of the assembly of the first, second, third, fourth  and  fifth  pluralities  to control  passage  of steam and air into and from the assembly, whereby the overwrapped  assembly  presents  a  challenge  of  graded decreasing porosity  from the biological  indicator  in the chamber to both sides of the overwrapped assembly.

Title: Method of extrusion molding and apparatus therefor
Inventor: FURUSAWA TOSHIHIRO
IPC: B29C48/08
Filed: 1991-01-21
Abstract: A method of extrusion molding, wherein the fluidity of a molding material in a die is kept satisfactory and the productivity of molded items having a uniform thickness is greatly improved, and an apparatus therefor capable of carrying out the method with reasonable construction of the apparatus. Molding is carried out while the die provided with an extrusion opening gap adjusting means is resonated. Furthermore, preferably, to make smooth the flow of the molding material in the vicinity of an extrusion opening of the die where the flow is most likely to stagnate in general, the extrusion opening gap adjusting means is attached to a part of the die, which forms an extrusion opening portion, whereby molding is carried out while only this part of the die is resonated. As a preferable mode, to attain effective resonance, the resonance frequency of the extrusion opening gap adjusting means is made equal to the resonance frequency of the die, and the extrusion opening gap adjusting means is attached to a nodal portion of the resonance. Furthermore, the extrusion opening of the die is allowed to coincide with the loop portion of resonance, i.e. a portion where the effect of vibrations is the strongest, so that the frictional resistance between the molding material and the surface in the vicinity of the extrusion opening of the die is reduced.

Abstract: ELECTRICAL CONNECTOR HAVING CASING                ABSTRACT OF THE DISCLOSURE       An electrical connector having a cover case for fixing therein the connector.  The cover case consists of two case halves arranged one upon the other.          The cover case having at a take-up opening of a cable an inner sleeve through which the cable passes.          The inner sleeve consists of two semicylinders fixed to the casing halves, respectively.  The cover case further has an outer sleeve which, after the inner sleeve is covered by the outer sleeve, is caulked to give urging force onto the inner sleeve on its outer side.  Abutment edges of the two semicylinders of the inner sleeve are wave-shaped edges waved in the abutment plane of the abutment edges so that the wave-shaped edges of one semicylinder are not coincident with the wave-shape edges of the other semicylinder.  In another aspect, abutment edges of the two semicylinders of the inner sleeve are provided with projecting plate members extending in the abutment plane of the abutment edges.          The abutment edges of the two semicylinders are prevented from coming out of the abutment against each other when the inner sleeve is subjected to compressive force when the cable is caulked.
