Abstract: ABSTRACT     A storage comprising load carriers which carry the goods to be stored and are vertically  stackable in a plurality of vertical piles closely disposed to each other.  The assembly includes pile beds having fixedly dis-posed support members which support the pile of load carriers at a spaced distance above the floor of the storage plant. At least one carriage is dis-posed to move below each vertical pile for insertion of the load carriers in the piles and for removal of them therefrom.  Each load carrier includes stationary downwardly extending rest members which cooperate with complemen-tary upwardly extending support members secured on each pile bed.  The rest members of the lower load carrier of the pile are arranged to be brought out and into engagement with the support members of the pile bed by vertical movement of the load carriers, which movement is performed by the carriage. When the rest members of the load carrier and the support members of the pile bed are out of engagement , the pile is laterally displaceable in relation to the pile bed by the carriage so that the rest members, the lateral extension of which is limited, can pass the support members vertically after said lateral dis-placement for insertion or removal of the lower load carrier of each pile.   A computer controls the insertion and removal of the load carriers.

Abstract: ABSTRACT OF THE DISCLOSURE A ripple register system is comprised of a plurality of similar in-dependent ripple register devices connected in series to form a data transmis-sion link between a source device and a receiving device.  This data transmis-sion link can function between independent synchronous operating units of a computer such as a pair of data buffers.  The ripple register system is useful in solving the prior art ready/resume problems of data transfer.  Data is transmitted and the ripple register devices absorb the data as compactly as necessary, within limits, to form the data path.  Each ripple register device consists of two data registers and two control flip flops.  The two data reg-isters are called the primary and secondary data ranks and the two control flip flops are the primary and secondary full-bits.  Each ripple register device has a clock control.  The data travels from the sending device through each ripple register to the receiving device while a control signal travels from the receiving device to the sending device.  No resume control signal is needed as in the prior art.  Data travelling through the ripple register de-vices in a transmission path may be analogous to a rippling effect because the timing sequence for the Hold signal from the receiving device travels in a reverse direction through the control flip flops of the ripple register devices to push the data along in stages.  This rippling occurs as a result of the ripple register holding data in secondary data ranks when the receiver stops data flow and while the transmitter is shutting off.

Abstract: EVAPORATOR ENTRAINMENT SEPARATOR                  ABSTRACT OF THE INVENTION      A separator assembly (30) for an evaporator comprises an ensemble of spaced-apart corrugated vanes (31) mounted in a hollow cylindrical configuration at the outlet (22) of the evaporator.  The spacing between adjacent vanes (31) is such as to prevent line-of-sight passage of vapor between adja-cent vanes (31) from the outer wall (33) to the inner wall (34) of the ensemble.  The upper end of the ensemble of vanes (31) is secured to an annular support member (32), which is secured to the evaporator circumjacent the outlet (22).  A closure member (40) is secured to the lower end of the ensemble.   The annular support member (32) and the closure member (40) prevent vapor from leaving the evapor-ator via any path other than a tortuous path between adja-cent vanes (31) in a direction from the outer wall (33) to the inner wall (34).  Droplets entrained in the vapor passing through the separator assembly (30) impinge upon the vanes (31) and are thereby separated from the vapor.

There is also disclosed a method for forming the tank.  The assembly in-cludes external circumferential clamping flanges which are provided by level winding a relatively narrow band of resin-impregnated filaments on the sidewall of the pressure vessel adjacent the midsection of the vessel.  The resin in the filaments is cured and the band and vessel are cut in a plane perpendicular to the longitudinal axis of the vessel so that band halves are provided adjacent each open mouth of the tank sections and those band halves constitute the afore-mentioned clamping flanges.  A circumferential, outwardly facing shelf is machined in a one-band half and an O-ring groove is machined in that outwardly facing shelf.  A circumferential, inwardly facing shelf is machined in the other band half and an O-ring is provided in the O-ring groove.  The band halves are telescoped together to form a pressure vessel with the O-ring pressed between the shelves.  The band halves are clamped together to form the assembly.

Abstract: Pressure Regulating Hydraulic Circuit and Valve Abstract For work vehicles, for example, cold weather can be a problem.  Disengaging the vehicle clutch aids starting by reducing engine loads during starting. Where the clutch is hydraulically actuated, it can be disengaged by keeping fluid pressures below required engagement pressure when supplying other elements common to the clutch hydraulic circuit.  Apparatus is provided which during starting directs fluid to, for example, pump drive bearings at less than clutch engagement pressure.  An input signal to the apparatus from the vehicle operator after engine start-up then builds pressure to activate the clutch while continuing to supply the pump drive bearings for lubrication. Upon a preselected fluid flow to the apparatus, such as at engine shutdown, the apparatus automatically returns to the condition at which available pressure levels are less than required for clutch engagement.  Thus, cold starting problems are substantially eliminated by auto-matically providing a clutch disengaged situation in the vehicle during engine start-up.

Abstract: ABSTRACT OF THE DISCLOSURE      A recoverable sleeve assembly is disclosed having an inner elastomeric tube and an outer rigid tube surrounding and secured to the inner tube holding the inner tube in outwardly stretched condition and wherein the outer tube extends axially beyond and covering at least one end of the inner tube and secured to that end of the inner tube.  The end of the outer tube extending beyond the end of the inner tube has a thickness equal to the total thickness of the inner tube plus the thickness of that portion of the outer tube that surrounds the inner tube.  The outer tube is a rigid thermosetting adhesive polyurethane comprising a polyester polyol reacted with an isocyanate whereby the outer tube is sufficiently adhesive to hold the inner tube in outwardly stretched condition but will peel from the inner tube upon impact or force or application of heat without need for a solvent.  The polyester polyol is disclosed as trimethylol propane branched glycol adipate polyol or polycaprolactone polyol modified with 1,4 butanediol reacted with the isocyanate.  The sleeve is applied around a substrate, and the outer tube is fractured by impact of force to allow the inner tube to shrink and the fragments of the outer tube to peel from the inner tube.

Abstract: IMPROVED POPCORN POPPING AND VENDING MACHINE                 ABSTRACT OF THE DISCLOSURE         A manually actuated popcorn machine which heats, pops kernels of corn, and delivers a specified amount of popped corn to a waiting container in a short time.  The popcorn machine includes a recirculating hot air conduit with an air blower portion, heating chamber portion, popping chamber portion for the kernels, a separating chamber portion, and a system of control baffles throughout the chambers for controlling the flow of air and popcorn.  The conduits include a continuous main chamber and a spur conduit: that leads to a cup dispensing chamber for placing the popped corn in a cup for distribution.  When actuated, the popcorn machine delivers a set amount of stored kernels to a screened grid in the popping chamber, the air from the blower moves past the heating element and through the screened grid to work around the kernels and to keep the kernels in motion on and above the screen grid and to move the popped corn away from the screened grid and into a cup.          When the hot air and the kernels reach a proper temperature, the kernels are popped and the volume and density are radically changed.  The air, whose currents are controlled by baffles, delivers the more buoyant popped corn up and into the spur conduit for delivery to a container while the hot air is recycled into the blower.
