Abstract: ABSTRACT     A sawing apparatus for sawing long lengths of material into shorter pieces having a predetermined length and discarding spoiled and short end pieces comprises a saw movable across a saw table formed in two parts which can be tilted independently of each other to tip sawn material into a receptacle.  The downstream part has a nose piece projecting just beyond the saw to support the leading end of a length from which a piece had just been sawn.  The apparatus also comprises exit and entry tables and a number of sensors for respectively detecting the leading and trailing ends of the lengths of material and for automatically initiating sequences of operations of releasable clamps for clamping the lengths of material, traversing movements of the saw, and the tiltable table parts.

Abstract: ABSTRACT OF THE DISCLOSURE      A slide fastener with separable and stop members including an insertion member and a reception member each associated with a respective row of coupling elements on a stringer half.  The members have complementary offset steps orthogonal to the slide fastener plane to prevent relative displacement of these members when they are inter-fitted in a direction perpendicular to the slide fastener plane and are mutually engageable.  A slider of generally Y-shaped channel configuration can be displaced upon the rows of coupling elements to interconnect and disconnect them.  The slider has arcuate slider flanks receiving the insertion and reception members between them and these members have arcuate surfaces corresponding to the curva-ture of these flanks and engageable therewith.  An abutment is provided to enable the coupling element to be drawn over one of these members, namely, the reception member; in a unidirectional manner and preventing withdrawal of the slider in the opposite direction.  The insertion member is shaped so that it can be fitted into the reception member when the slider is disposed over the latter.

Abstract: ABSTRACT OF THE DISCLOSURE Linear and rotary stepper motors are provided with predetermined stop positions which differ from the magnetically inherent stepped positions of the stepper motors.  The predetermined stop positions result from sensing the distance the rotor or slider is from a predetermined stop position and generating a signal including a position component representing the distance to the stop position and a velocity component representing the velocity at which the stop position is. being approached.  The signal is in turn utilized to generate a current reference signal for the motor which is compared with the current of the motor so as to stop the motor at the predetermined stop position.

Abstract: ABSTRACT OF THE DISCLOSURE A turbine mixer for a polyethylene reactor of the stirred autoclave type in which a turbine rotor is mounted on n rotating stirrer shaft extending along the longitudinal axis of the reactor and a turbine stator is mounted adjacent to and upstream of the rotor. The turbine mixer is positioned in the final stage of a three-stage, stirred autoclave reactor, and a baffle plate is positioned so as to extend across the reactor at the inlet to the final zone. The mixer produces intense stirring of the reactor materials within the final stage, but does not cause significant backmixing into the reactor zone immediately upstream thereof. The turbine mixer may also be utilized in other zones of the reactor wherein intense axial mixing of the reactor materials is required, in which case the baffle plate would be omitted so as to produce intensive axial mixing of the reactor materials within that zone.

Abstract: TITLE          COMSINATION PRESSURE-VACUUM RELIEF AND ANTIPOLLUTION VALVE     ABSTRACT OF THE DISCLOSURE            A combination venting and antipollution device for a shipboard liquid storage tank.  A closure wall devides the vent conduit into a lower tank chamber in direst communication with the vent opening.  A spring-urged vlave closure member opens or closes an opening through the closure wall.  Low pressure in the tank moves the valve closure member down into a lower open position, to admit air or other fluid to the tank; high pressure in the tank moves the valve closure member up into an upper open position to vent air from the tank.  A hydrostatic pressure chamber open to the atmosphere houses a sealed bellows, and a spill-lock balve secured to bellows normally opens to the vent a spill-lock chamber on the vent side of the valve closure member.  However, when the pressure in the pressure chamber (or manual action) compresses the bel-lows (as when the ship sinks), the bellows moves the spill-lock valve to close the connection to the vent and cause the fluid from the tank chamber to flow into the spill-lock cham-ber, to bear upon a spill-lock piston there.  In this condi-tion, the tank pressure acts on the spill-lock piston to pre-vent the valve closure member from moving up into its upper position until the pressure in the tank chamber is well above that then present in the valve space, but the tank pressure does not restrain the valve closure member from moving down into its lower open position.  Salvage operation is also pro-vided for.
