Abstract: Abstract of the Disclosure A machine for detopping fruits and vegetables, specially suited for the decapping of strawberries by severing the top therefrom, comprises an endless upwardly-inclined loop type con-veyor mounted on a sub-frame which is in turn mounted on a main frame for horizontal orbital motion relative thereto.  The con-veyor consists of a receiving station section inclined to the horizontal so that already decapped produce discharges against the travel of the conveyor, and a severing station section at a higher level than the receiving station section, a downwardly-extending discharge section and a return section.  The conveyor consists of parallel rollers alternate ones of which are posit-ively driven by pinion gears engaging rack members at the side so that  cooperating pairs will grip the tops.  Only product that has been so gripped can be conveyed upwards by the conveyor and presented to a transversely moving endless band severing knife at the severing station.  The orbital motion causes the product to be orientated into a position which facilitates gripping of the tops by the cooperating roller pairs.

Abstract: ABSTRACT OF THE DISCLOSURE             A method for removing hydrogen sulfide from a hydrogen sulfide entrained gas comprises the steps of bringing the hydrogen sulfide entrained gas into contact with an alkaline absorption solution with a pH of 10 to 14 to cause hydrogen sulfide in the gas to be absorbed into an alkaline absorption solution, subjecting the resultant absorption solution to a DC electrolytic treatment whereby an alkaline solution is separated into a cathode chamber and sulfur and sulfuric acid are separated into an anode chamber, and circulating as the alkaline absorption solution the alkaline solution produced within the cathode chamber.  This constitutes a closed system, thereby completely eliminating a cause for public nuisance.

Abstract: ABSTRACT   In a reactive metal-water electrochemical cell, a configuration utilizing waste heat and evolved hydrogen gas for pumping electrolyte through the cell.  More particularly, the cell is in a vertical, hollow tubular con-figuration with the reactive anode being bonded to the interior surface of the tube casing and a coiled metal screen cathode being positioned within the tubular cell and contacting the anode over essentially its full working sur-face.  As the anode is consumed in operation, by reaction with an aqueous electrolyte filling the interior cavity of the tubular configuration, the coil configuration of the cathode forces it to expand and maintain contact with the anode.  During operation, evolved waste heat and gas cause a flow of electrolyte through the interior of the cell.

Abstract: ABSTRACT OF THE DISCLOSURE    The stack forming device according to the invention comprises a traction surface which is rotatably driven and means for keeping the portion of the trailing edge of a sheet to be stacked in contact with the traction surface so that the trailing edge of the sheet is displaced in synchronism with said surface.  This displacement is carried out over a period which follows the abutment of the leading edge of the sheet against a stop provided on a stacking platform.  As a con-sequence the sheet acquires a convex configuration and is finally propelled against the platform or the preceding sheet after release by the traction surface.     The device may be equipped with supplementary blowers in order to facilitate the release from the traction surface.          It is of particular interest for high speed stacking of photographic film sheets, preferably double-side  coated ones.

Abstract: ABSTRACT OF THE DISCLOSURE         Heat balance of a fractionation column is controlled and maintained by obtaining three differential temperatures between selected temperature-sensing points along the height of the column.  A signal representing one of the delta-T's is employed in regulating the quantity of reflux returned to the rectification zone.  The remaining two delta-T's are conjunctively utilized to regulate the enthalpy (heat-input content) of the reboiled liquid bottoms stream being return-ed to the reboiler section of the column.  With respect to the latter, a selected one of the two delta-T signals is multiplied by a multiplier representing the ratio of the number of trays between the temperature sensing points sup-plying the non-selected delta-T signal to the number of trays between the temperature sensing points supplying the selected delta-T signal.  A signal representing the resulting product is correlated with the non-selected signal, and the signal representing the resulting relationship is utilized to regulate the degree to which the returned liquid bottoms material is vaporized.

Abstract: METHOD AND APPARATUS FOR MEASURING PRESSURES                              Abstract A pair of pressure sensing probe tubes are placed in the fan discharge of a turbofan engine, aft of the outlet guide vanes (OGVs) the tubes being circumferentially spaced by a fraction of the OGV pitch. A comparing means receives both pressures sensed by the double-barrelled probes and aerodynamically actuates to automatically select the higher of the two pressures. An accurate pressure indication representative of the mainstream pressure is therefore obtained despite the localized lower pressure turbulence area that may be caused by the presence of the upstream outlet guide vane(s).

Abstract: APPARATUS FOR DUMPING AND COLLECTING CORROSIVE SUBSTANCES FROM AUTOMOTIVE BATTERIES             Abstract of the Disclosure A novel battery dumping apparatus is described which is uniquely suited for dumping corrosive substances, such as battery acid, simultaneously from a number of automotive batteries. The novel apparatus generally comprises a sealed tube adapted for rotation through an arc of less than 360 degrees. Within the tube are disposed two parallel spaced apart baffles which together form a sealed battery processing channel. This battery processing channel is pierced by a plurality of rods disposed in a plane which bisects the aforementioned baffles. These rods are ultimately caused to rotate in opposite directions by a gear drive disposed outside of said battery processing channel but within said tubular member. These gears are, in turn, caused to drive said rods by a pneumatic motor which is mounted outside of said tubular member.           A plurality of roller members, one for each rod, are disposed within the battery processing channel, alternate ones of said rollers being pinned to their respective rods to produce movement of batteries resting thereon. Four unitary inflatable members are appropriately positioned on the aforementioned baffles for the purpose of selectively gripping groups of batteries to be inverted.           A novel hydraulic piston is utilized as a safety interlock to prevent batteries in the inverted position from being released by these tubular gripping means.     These gripping means further coact with the battery processing channel to prevent latent liquids from showering down upon batteries during the inversion process. Additionally, novel sealing and pouring means disposed at opposite ends of the tubular member provide for safe collection of the dumped corrosive liquids.

Abstract: ABSTRACT OF THE DISCLOSURE        A hard compact material, such as rock, is broken by forcing a longish mass body of relatively imcompressible fluid, such as water, against the material to be broken.  The mass body is caused to impact the material at a momentum necessary for breaking the material.  The momentum is generated by supplying the fluid to a storage chamber against the effect of a thrust load acting upon the fluid in the storage chamber.  When a sufficient amount of fluid has been supplied the fluid in the storage chamber is forced toward the material to be broken by the effect of the thrust load.
