Abstract: ABSTRACT OF THE DISCLOSURE            A filter assembly incorporates a system for jacking  a filter canister      into and out of engagement with a filter head     .   A threaded jackscrew      is mated to a threaded portion of the filter head and rotatably mounted  on  the filter canister,  but  longitudinally confined  near the canister top.    The  assembly  can accommodate  a second class lever      the fulcrum  of which  lies  in  a notch or other recess     in  the filter head.    The jackscrew includes a plurality  of circumferentially-spaced  lugs against which a portion of  the  lever can act.    The manual  application  of force  to  the free end       of the lever  creates  a mechanical  advantage at the jackscrew lugs       such that  a  torque  sufficient  to free  and  turn   the jackscrew can be generated.   Repeated pivoting of the lever  against  successive lugs of the jackscrew in  a ratchet-like  manner unscrews the jackscrew,  and  the captive canister, from the filter head.

Abstract: ABSTRACT OF THE DISCLOSURE     The attached specification discloses a method of forming interlocking vinyl siding panels.  A sheet of vinyl is extruded with a V-shaped bend along one of its edges, and a Z-shaped bend intermediate its edges.  The extruded sheet of vinyl is then formed, while in a hot, semi-viscous state into the final siding profile.  As the siding profile is formed, the V-shaped bend is formed into a first locking profile and the Z-shaped bend is formed into a second locking profile.  The first locking profile is dimensioned for a snap-type engagement with the second locking profile of another similarly formed siding member.  The panels so formed, due to the ease with which they can be inter-locked, can be speedily applied to a building by one man working without assistance.

Abstract: TRAVEL/LIFT INHIBIT CONTROL     Abstract A lift truck of the order-picker type is provided with an automatic control system for safeguarding the operation against certain conditions. The electronic control system is responsive to an electrical height signal corresponding to the height of the lift fork to regulate or limit the other operational functions of the truck.  The speed control channel compares the speed signal with a speed command signal and produces a speed control signal of limiting value.  A travel interrupt channel compares the height signal with the steering angle and interrupts the vehicle travel if the steering angle is excessive.  Usually, the high speed lift is cut-off when a predetermined height is reached; the lowering of the upright is disabled at a predetermined lower limit subject to manual override.

Abstract: ABSTRACT : "Full adder circuit".           So as to generate quickly the several carry signals in a full adder circuit (for example a 40-bit circuit), tile circuit is divided into a plurality of sub-circuits of a first type, in which provisional carry signals are generated in parallel. Carry look-ahead circuits are of a dual construction, each first carry look-ahead circuit receiving a logic "O" and each second carry look-ahead circuit receiving a logic "1". So the provisional carry signals generated are complementary, from which the carry signal proper is selected with the aid of a multiplex switch. The multiplex switch is con-trolled by the carry signal generated in a preceding sub-circuit of the first type. Since a multiplex switch operates faster than 3-bit or 4-bit wide carry look-ahead circuits, which operate in parallel in groups, the carry signals are consequently generated faster.
