Abstract: ABSTRACT OF THE DISCLOSURE         A pair of arms are pivoted together by one end there-of and normally urged apart by a heavy-duty spring.  A flexible snare consists of a snare loop and a free or standing end pass-ing through a ring on one end of the snare in a form of a runn-ing noose.  The free end passes through an eye on the other end of one of the arms and is secured to a trigger lever pivotally mounted on the other end of the other arm.  A trigger loop is pivoted to said one arm and in one position holds the trigger lever with the trap in the set position and engages the other arm with the trap in the locked position.  When in the set posi-tion, a pull on the noose displaces the trigger lever slightly so that the spring pressure between the two arms springs the trap and tightens the noose.

Abstract: ABSTRACT OF THE DISCLOSURE           An animal trap having two similar frames each having jaw forming sides that lie in a common plane and ends extending therebetween to support the jaws.  The ends have a central portion in which the frames are pivotally connected through adjacent ends for rotation about a common axis between set and closed positions.  Outer portions on each side of the central portion extend to the jaws.  At least one actuator is capable of rapidly and forcefully effecting the rotation.  The actuator has two arms spring-biased at one end so that the other ends, which terminate in rings encircling adjacent ends of both frames on opposite sides of said axis, would, if unobstructed, move appart to a distance substantially greater than the length of the frame ends.  A trigger means releasably maintains the trap in the set position.  The trigger means comprises a pivotally mounted treadle extending between the frames of the trap.          Engagement means are associated with the treadle.  A lever extends, when the trap is in the set position, from engagement with the engagement means to engage both frames of the trap to retain them in set position. Engagement with one frame is by a pivotal link whereby movement of the treadle releases the engagement of the lever with the engagement means to release the trap from the set position.  The trap has no immediately visible obstruction when in the set position and the trigger displays good sensitivity.

Abstract: ABSTRACT OF THE DISCLOSURE A vector CRT display apparatus for faithfully reproducing an analog signal having high frequency components include an A-D converter, a digital minimum/maximum circuit and a re-circulating shift register to derive from the signal, in successive sampling periods, two digital words representing, respectively, a minimum amplitude value date point and a maximum amplitude value data point of the signal.  In each sampling period, the minimum/maximum circuit stores in the memory the most relevant of the minimum and maximum amplitude values and determine whether the remaining values should be held over to the next sampling period before it is stored, or can be discarded.   As a result, if new minimum and new maximum amplitude values occur in the same sample period, one will be loaded into the memory and the other will be held over and loaded into the memory in the next sample period.   By storing only the most relevant of the minimum and maximum amplitude values, the size of the memory required, and its cost are substantially reduced; additionally, the storage of only important values in the memory for later display contributes to a uniformity of brightness of the display.

Abstract: Abstract of the Disclosure:  An improved fluid flow control apparatus is utilized in association with a vehicle having a single variable displacement pump for supplying fluid to both a steering apparatus and an auxiliary apparatus.  The fluid flow control apparatus includes a pair of variable size orifices one of which is associated with the steering apparatus and the other of which is associated with the auxiliary apparatus.  Upon actuation of either the steering or auxiliary apparatus, the size of the associated orifice is varied to provide a variation in a load signal and effect a change in the displacement of the pump.  During simultaneous operation of both the steering and auxiliary apparatus, a priority valve assembly is utilized to block fluid flow to the auxiliary apparatus if the fluid out-put from the pump is insufficient to satisfy the demand for steering fluid.  The priority valve assembly includes a main valve member with an internal chamber in which a secondary valve member or piston is disposed.  Upon initiation of a steering operation with the auxiliary apparatus in an inactive condition, the secondary valve member moves toward a closed position. If at this time the demand for steering fluid is sufficiently great, the secondary valve member blocks fluid flow to the auxiliary apparatus.

Abstract: PROCESSES OF MAKING POROUS MEMBRANES AND THE MEMBRANE PRODUCTS     Abstract This invention covers a continuous process for making a polymeric membrane having at least 60% or more of its volume taken up by intercommunicating pores of substantially uniform size below about 25 micrometers.  The process consists of applying a layer of a polymer solution on a rigidly supported backing belt, then passing the belt through a formation bath that includes solvent plus a non-solvent for the polymer that is miscible with its solvent.  The bath is recirculated at a substantially constant, preselected composition.  The porous structure of the membrane is sub-stantially completely formed in the formation bath.  The process includes extracting any residual solvent from the porous membrane, then drying the membrane.  To produce membrane material of consistent, uniform characteristics and quality, the formation bath is maintained at the pre-selected composition.  Either skinned molecular filtration membranes or microporous membranes may be produced by adjust-ing process parameters, such as the composition of the forma-tion bath.

Abstract: PRINTING SYSTEM                  Abstract of the Disclosure A printing system is disclosed wherein ink is emitted from a nozzle as entrained in a jet of air.  The ink is introduced onto an ink wall from an ink passageway and a fluid passageway has an outlet directing air at an angle onto this ink wall to cause the ink to flow along the wall and form into ligaments and eventually part from that wall as droplets.  The droplets part from the ink wall primarily at a tip wall which diverges out of the air stream.  In a preferred embodiment there are two such ink walls and the two flows of ink droplets converge to form a single stream.  A printing head contains a plurality such as seven such nozzles in a row and then relative movement of the printing head and the printing surface together with controlled pulses of the emitted ink will cause alphanumeric characters to be imprinted on the printing surface.  This provides a means for direct printing of pertinent label information on the surfaces of production items such as rolls of paper, pulp bales, paper board bundles or other unitized commodities with a suitable exterior surface.

Abstract: Abstract A copy production machine selectively inter-leaves copy separation sheets between successive copy jobs, subjobs or job portions.  The copy separation sheets can be from the same copy sheet supply source or from an alternate source.  The supplied copy separation sheets need not be operated upon by the copy production machines for receiving an image.  Such sheets may have been preimaged under certain situations.  When copy sheet supply means have diverse size copy sheets the separation mode may be inhibited.  The number of separa-tion sheets supplied is a predetermined relationship between the number of copy receiving bins in an output portion receiving the copy separation sheets as well as the number of copies produced from a single image.  The effective capacity of a collator is extended by such interleaving plus a programmable control that tallies copies made versus copies selected greater than the capacity of a collator such that the collator job is automatically segmented.
