Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus and method for increasing the throughput of a chromatographic system by passing several samples in seriatim through tandemly connected first and second chromatographic columns.  The eluant from the first column is sampled, or fractionated, and fractions of each of the samples are passed through the second column for further separation.  A switching of the sampling valve, disposed between the first and second columns, effects such fractioning.  The pumping rate for the second column may be different from that of the first column and allows that two or more sample fractions can occupy the second column concurrently.            Docket 2120-A

Title: Backhoe swing cylinder hydraulic  circuit
Inventor: HANSEN CHARLES A
IPC: E02F3/43
Filed: 1979-09-24
Granted: 1981-12-29
Abstract: ABSTRACT        As the backhoe boom 19 swings into a swing stop, hydraulic fluid is trapped in the head end 28 of the swing side cylinder 24.  This trapped fluid is discharged through a cylinder relief valve, thus absorbing the boom kinetic energy and providing a smooth deceleration of the boom.  Fluid discharged from the relief valve 47 is routed to the rod end of the swing cylinder and the head end of the opposite cylinder.  Because of the swing linkage geometry, the cylinder rod 30 of the other cylinder had passed over the pivot axis about which the backhoe boom was swinging and thus the piston 29 of the other cylinder was caused to move in the same direction as the swing side piston 29.  The movement of this piston can be utilized to provide additional deceleration torque as long as no voiding is permitted to occur in the head end of this other cylinder.  Voiding only occurs when the backhoe swing control lever 38 is released prior to the backhoe boom reaching the swing stop.  Voiding does not occur when the control lever 38 is maintained in a full power-on or is stroked in the power-on mode until the swing stop is contacted.  Fluid from the swing side cylinder relief valve is routed to provide the necessary fluid to prevent such voiding.  The routing of the fluid from the swing cylinder to the other cylinder assures that the boom deceleration is independent of whether the control lever is stroked or released.

Abstract: ABSTRACT OF THE DISCLOSURE A forced steering mechanism is connected to a truck to steer an axle and associated wheels.  Coupling means are provided for loosely con-necting the car body of a vehicle to the truck and the forced steering mech-anism.  The coupling means permits relative lateral movement between the car body and truck while maintaining the forced steering mechanism in a position so as to permit self steering, but no forced steering when the vehicle is moving over tangent or rectilinear tracks.  At the same time the degree of such lateral movement and amount of self-steering is limited. The coupling means causes the forced steering mechanism to become operative when the ve-hicle is moving over sharply curved tracks.

Abstract: Abstract of the Disclosure A method of feeding hogs is disclosed.  The method in-cludes the steps of providing all the hogs with all the feed they care to consume for a limited feeding period of time, and thereafter denying all feed to all the hogs for a limited feedless period of time.  Pref-erably, weaner hogs are provided with all the feed they care to consume during three separated, limited feeding periods of approximately two hours each per day.  These feeding periods are alternated with three feedless pe-riods during which all feed is denied to all the small hogs.  This feeding regime is maintained until the hogs weigh approximately 100 pounds.  Thereafter, two limited feeding periods are provided each day until the hogs reach market weight. In this way, hog weight gain per day is maximized and the amount of feed consumed per pound of hog weight gained is minimized.            Apparatus for carrying out this feeding method is also disclosed.  The apparatus includes a feed pan or trough, a high capacity feed delivery conveyor, and a timed feed shut-off means interposed between the feed trough means and the feed delivery conveyor for alternatively delivering and preventing delivery of feed to the feed trough.  If desired, a water nozzle can be located above the feed trough to deliver water to the hogs during a feeding period.  A timed water shut-off means can be interposed between the water nozzle and the water delivery pipe for alternatively permitting and preven-ting delivery of water to the water nozzle.

Abstract: AUTOMATIC DEVICE FOR SYNCHRONIZATION OF PRIME MOVER WITH ELECTRICAL GRID      ABSTRACT OF THE DISCLOSURE A control circuit is disclosed for synchronizing a prime mover or electrical generator with an electrical grid or power line such that when the prime mover is connected to the grid;       a)  the instantaneous phase and slip are within allowable limits;   b)  the phase and slip expected at breaker closure, as contrasted to the instantaneous measured phase and slip, will be within given trajectory, i.e when they are closest to their most desired values during the given transition.  The circuit includes a clock for measuring the phase difference between the power line voltage and the generator voltage and means for calculating the rate of change of the phase difference which is a measure of difference of the respective frequencies known as the slip.  The trends of phase and slip are then extrapolated by the amount of time it takes the breaker to close and a command for breaker closure is issued when the above three conditions are simultaneously satisfied. speed matching can be caused by having the circuit produce a signal to raise generator speed when the slip is less than a given lower limit and by producing a signal to reduce generator speed if the slip exceeds a set upper limit.

Abstract: ABSTRACT OF THE DISCLOSURE:         A traverse motion used in combination with a device for winding a continous elongate element such as a strand consisting of a large number of glass filaments drawn through a bushing with a large number of nozzles.  In the traverse motion of the type including a scroll cam with an endless cam groove consisting of at least one pair of right- and left-hand grooves joined at each end and a strand guide which has a cam follower fitted in the endless cam groove of the scroll cam and is adapted to reciprocate along a straight path in parallel with the axis of the shaft of the scroll cam when the latter is rotated, the lead angle of the endless cam groove is increased adjacent to its ends or adjacent to each returning point of the cam follower so that the guide is increased in velocity adjacent to each returning point.       With a conventional scroll cam the traversing motion of the strand at the downstream of the strand guide lags behind that of the strand guide in the case of winding the strand into package on a spool so that the ends of a package being formed are increased in diameter as compared with the intermediate portion between them.  When the strand guide is increased in the manner described above adjacent to each returning point, the flange-like increased-diameter distortions at the ends of the package can be avoided and high-quality packages with square ends can be produced.
