Abstract: ABSTRACT OF THE DISCLOSURE      A mobile arrangement for improving a track bed by interposing a layer of sand between the subgrade and ballast comprises a first self-propelled vehicle including a frame, a hoist mounted on the frame for lifting an assembled track section off the track whereby a trackless renewal section is created and a conveyor and discharge and distributing chute for ballast and sand, the vehicle frame having a length bridging the trackless renewal section and respective track sections adjoining the trackless renewal section at respective ends thereof in the regions of the vehicle frame ends.  A second self-propelled vehicle includes a frame whose one end faces one end of the frame of the first vehicle in one of the adjoining track sections, a ballast excavating chain and a conveyor for the excavated ballast.  A respective triple-undercarriage arrangement supports the one end of each vehicle frame, each triple-undercarriage arrangement consisting of two on-track undercarriages and an off-track undercarriage.  Another undercarriage supports the frame of each vehicle and the distance between the triple-undercarriage arrangement and the other undercarriage supporting each vehicle frame exceeds the length of the assembled track section.

Abstract: ABSTRACT     A process is provided for expanding tobacco by means of overwetting the tobacco to a moisture content of at least 20%, preferably from 20% to about 80%, and then overdrying the tobacco in a period of a few seconds in a turbulent steam atmosphere to a moisture content of less than 7% to achieve increased filling power.  The overwetted tobacco is preferably dried to a moisture content of less than 7% within a time period of less than 5 seconds.  It is preferred that the tobacco be dried to a moisture content of less than 5%, and even more preferred that it be dried to a moisture content of less than 3%.  The turbulent steam drying atmosphere preferably comprises at least about 60% steam.  Typically, the tobacco is bulked for from about 1/4 hour to 4 hours after it is overwetted to allow the moisture to be distributed within and absorbed by the tobacco cellular structure of substantial portions of the tobacco.  Subsequent to overdrying, the tobacco is typically remoisturized to a processing moisture content of about 12%.

Abstract: Abstract of the Disclosure A hydraulically operated dockboard comprising a ramp which is hinged at its rear edge to the frame of the dockboard, and a lip is hinged to the forward edge of the ramp and can be pivoted between a down-wardly hanging pendant position and an extended posi-tion.  A main hydraulic cylinder unit interconnects the frame and the ramp, and by operating the cylinder unit the ramp can be pivoted upwardly from a horizon-tal cross traffic position to an upwardly inclined position.  As the ramp approaches its fully raised position, hydraulic fluid is conducted from the main cylinder unit to a lip lifting cylinder which inter-connects the ramp and the lip.  Introducing fluid to the lip lifting cylinder will act to pivot the lip to the extended position.  When operation of the main hydraulic unit is discontinued, the combined weight of the ramp and the lip will cause the ramp to descend, and when the ramp descends to a predetermined position, the hydraulic fluid will return from the lip lifting cylinder to the main cylinder unit to thereby permit the lip to pivot by gravity to the pendant position.

Abstract: ABSTRACT OF THE DISCLOSURE A method for manufacturing a sewing thread comprising the following steps: drawing an undrawn polyester multifilament yarn; preliminarily heat treating the drawn yarn at an effective heat treating temperature before false twisting; then, false twisting the heat treated synthetic multi-filament yarn at a temperature of at least 150°C.; subjecting the false twisted yarn to a fluid jet treatment under the slackened condition so as to intermittently interlace in a lengthwise direction constituent filaments of the yarn and so as to form protruded portions protruding from the surface of the yarn; and post-heat treating the interlaced yarn at an effective heat treating temperature being higher than the heat treating temperature of the false twisting. By this method, a thread suitable for sewing can be obtained. The produced sewing thread comprises at least one polyester multifilament yarn, in which thread constituent filaments of the multifilament yarn are intermittently interlaced along the lengthwise direction thereof, and a part of the constituent filaments of the multi-filament yarn protrudes from the surface of the multifilament yarn; and the torque of the sewing thread is very small in spite of the fact that substantially all filaments constituting the sewing thread have been subjected to the same false twisting.

Abstract: Elevator Buffer Abstract A plate is attached to a rail which moves verti-cally in a housing.  The housing includes a brake which rubs on one side of the rail; on the other side, there is a roller.  A leaf spring is positioned between the housing and the roller.  When the rail moves verti-cally in one direction, the roller is pushed progressive-ly harder against the rail.  This squeezes the rail against the brake, creating a braking force on the rail that increases, to maximum, in relation to distance the rail moves.  This arrangement may be used as a buffer for an elevator cab or counterweight in an elevator.
