A double acting cold trap equipped with a set of exhaust gas condensing fins and a set of exhaust gas condensing plates is disclosed. The invention also discloses a double acting cold trap that incorporates a deflecting plate to direct the exhaust gases over the condensing fins and plates in a serial fashion. This increases the efficiency of the collection of unwanted particles.

A fast-acting valve includes an annular valve seat that defines an annular valve orifice between the edges of the annular valve seat, an annular valve plug sized to cover the valve orifice when the valve is closed, and a valve-plug holder for moving the annular valve plug on and off the annular valve seat. The use of an annular orifice reduces the characteristic distance between the edges of the valve seat. Rather than this distance being equal to the diameter of the orifice, as it is for a conv...

A double-acting, weight distributing trailer hitch includes a drawbar assembly and a hitchhead assembly. The drawbar assembly is releasably connected to a tow vehicle and includes a first coupling component at its rearward end. The hitchhead assembly includes a second coupling component and a rearwardly extending drawbar extension, which are pivotably connected along substantially vertical axis by a yoke. The drawbar extension is pivotally connected to the yoke by a cam. The drawbar extension is...

A synchronizer (18) includes cone clutch friction surfaces (24,48 and 26,50) for frictionally synchronizing gears (14,16) to a shaft (12), and jaw clutch teeth (28,30) engagable with jaw teeth (36a,36b) defined on a shift sleeve (34) for positive connecting the gears to the shaft. A plurality of self-energizing/blocker members (62) transmit shift force applied to the shift sleeve and self-energizing force to friction rings (40,42) via blocker surfaces (44r,44s,44p,44q) defined by blocker members...

A dual acting underbody truck bed hoist is provided which exhibits increased lifting efficiency and safety. The hoist, in some embodiments, further includes an alignment of its various pivots and booster arm so as to maximize the height achieved during initial lifting to the breakaway point with the dump bed.

A compound of Formula I ##STR1## or a pharmaceutically acceptable salt thereof wherein n is 1 or 2; R.sup.1 and R.sup.2 are independently H (provided only one is H at the same time), --OH, CN, CH.sub.2 CN, 2-- or 4--CF.sub.3, CH.sub.2 CF.sub.3, CH.sub.2 CHF.sub.2, CH.dbd.CF.sub.2, (CH.sub.2).sub.2 CF.sub.3, ethenyl, 2-propenyl, OSO.sub.2 CH.sub.3, OSO.sub.2 CF.sub.3, SSO.sub.2 CF.sub.3, COR, COOR, CON(R).sub.2, SO.sub.x CH.sub.3 (where, x is 0-2), SO.sub.x CF.sub.3, O(CH.sub.2).sub.x CF.sub.3, S...

The application discloses double-acting pusher centrifuges comprising a rotatable sieve drum (6) which carries out separation of a mixture (17) into liquid and solid matter portion (40) in the form of filter cakes (14, 15). A centrally located pusher floor device, movable to-and-fro along the axis (9) of the sieve drum (6), pushes out alternately to one side and the other by its outer annular region the filter cake (14) deposited since the last clearing of the drum region. The pusher floor is pr...
