Abstract: ABSTRACT OF THE DISCLOSURE          An electric incandescent lamp comprising an axially extending filament in a tubular vitreous envelope has improved filament supports of wire whose outer turns are formed as hex-agonal loops comprising straight segments with angles between successive segments.  The sharp bends at the angles decrease the springback and unwinding of the support when it is released from the mandrel, so that variations in support loop diameter with wire tension and size are reduced.  The support may be fabricated through a new method and apparatus on a forming mandrel by engaging a wire in a slot in an exposed end fa? simulating a shallow helicoid.  As the mandrel revolves, at least one full turn is wound around its periphery (which may be hexagonal) to form the outer envelope-engaging loop.  The wire is then bent radially inwards at the shoulder of the pro-jecting portion of the helicoid face to wind filament-engaging turns around the filament and wire mandrel which extend through an axially aligned aperture in the forming mandrel.  The formed support anchored to the filament is then stripped laterally off the exposed end face of the mandrel.

Abstract: METHODS AND APPARATUS FOR DUCTLESSLY CIRCULATING AND SELECTIVELY SUPPLEMENTALLY HEATING LARGE VOLUMES OF AIR IN INDUSTRIAL FACILITIES                 Abstract An apparatus for ductlessly circulating large volumes of air in industrial facilities and the like includes an up-standing structure which defines a vertically extending chamber.          Openings are provided in lower and upper portions of the struc-ture and communicate the chamber with lower and upper strata of ambient air.  A blower assembly is housed within the struc-ture intermediate the lower and upper openings.  In operation, the apparatus is positioned substantially centrally in a room, and the blower assembly is energized to move air upwardly through the chamber.  The lower and upper openings are arranged such that air from the lower stratum is drawn substantially radially toward the lower openings, and such that air dis-charging from the upper openings into the upper stratum moves substantially radially outwardly toward walls of the room.          The effect of this type of operation is to establish a primary substantially toroidal air flow circulation beside the appara-tus, and to induce the establishment of a secondary substan-tially toroidal air flow circulation above the apparatus.  The primary and secondary circulation tori promote a thorough intermixing of air from all parts of the room and promote temperature uniformity throughout the room.  In the preferred embodiment, the apparatus is portable and its upstanding structure is provided by a stacked array of lower, intermediate and upper modules or sections.  A heater assembly for selec-tively supplementally heating air in the chamber is preferably housed in an intermediate one of the modules or sections.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention relates to the long term stabilization of proteinaceous food products both for humans and for animal consumption, having a moisture content exceeding 50% and preserved against micro-biological spoilage by a pH value of 4.5 or below.  The long term stabilization of such products is enhanced by the presence of viable homofermentative acid producing organisms, notably lactic bacteria, together with available fermentable carbohydrate.  The presence of the active bacteria with fermentable carbohydrate enables the product to resist or compensate for changes, such as an incipient rise in pH value, which would otherwise lead to deterioration.  Additional stability has been observed in products in which the bacteria have undergone active fermentation although the reason for this additional stability is obscure. In the preferred process the pH value of a proteinaceous product is reduced to a value in the range 5.0 to 4.0 and fermentation of the bacteria is then brought about. whereby the pH value of the product attains a final value not exceeding 4.5, if necessary with a lowering of pH value by the action of the bacteria.  In preferred embodiments of the process of food grade acid is added to reduce the pH of the product to 4.5 to 4.9 and the final pH value of the product lies in the range 4.3 to 3.8.  The process provides products of greater long term stability than prior art products of similar pH value and more especially enables stable products to be produced from raw materials containing high levels of microbiological contamination.

Abstract: ABSTRACT OF THE DISCLOSURE           An interlock system for a fuel dispensing nozzle which prevent its operation until the nozzle is properly inserted into the fillpipe of a vehicle.  The interlock system includes an actuation system which responds to the nozzle resting on the fillpipe opening at a predetermined point along the discharge spout of the nozzle and a valve located at the outlet of the vent tube from the automatic shut-off system.  The interlock system is biased in such a manner that the valve remains closed at all times unless the nozzle is resting in the fillpipe in the proper manner.  In this manner the valve causes the automatic shut-off system to disable the nozzle when it is properly inserted in the fillpipe and permits the automatic shut-off system to act in its normal fashion when properly inserted, so that the nozzle is shut off when the liquid level in the fillpipe reaches the end of the discharge spout.

Abstract: ABSTRACT OF THE DISCLOSURE         An instantly refuelable energy conversion system com-prises a multicell array wherein each cell has a cathode, a solid anode fuel selected from the class consisting of iron, zinc and nickel and a ferric (and/or +3 valence nickel or zinc) chloride liquid oxidizer.  In power delivery (discharging) e.g., using iron alone, the reactions are:      At the anode, Fe?Fe+++ 2e yielding 0.44 volts, At the cathode, Fe++++e?Fe++ yielding 0.75 volts, the overall reaction being:          Fe + 2FeCl3?3FeCl2, i.e., 1.2 volts overall.          These reactions are reversible for electrical charging purposes The oxidizer is recirculated continuously and chemical reaction between the oxidizer and solid fuel in the fully charged or partially charged system is limited by a diffusion barrier be-tween the oxidizer and fuel so that reactions therebetween are predominantly electrochemical.  The system is characterized by continuously countering the tendency of rising pH of anolyte, and/or of contaminant accumulation therein, to maintain stable operation over long periods, e.g., by using a main energy con-version system anolyte as a catholyte in an auxiliary, over-driven energy conversion system which at the same time the catholyte of the main system serves as anolyte of the auxiliary system with reliance on the richness of the liquid in hydrogen ion and Fe+++ ion to chemically attack any elemental iron formed in the auxiliary system thereby further preserving stability.          The iron may be substituted in whole or in part by zinc and/or nickel.

Abstract: Torque Equalizer for a Hydraulically Driven, Four-Wheel-Drive Vehicle Abstract of the Disclosure A two-axle, four-wheel-drive vehicle has separate hydraulic drive systems to drive the front and rear pairs of traction wheels.          Each drive system includes a hydraulic motor that is powered by its own variable displacement pump.  The torque developed by the motors, and the hydrostatic drive pressure, depend on the volume of fluid flow from the pumps.  Under certain conditions, the hydrostatic drive pressure to the two motors becomes unbalanced.  A torque equalizer valve is interconnected between the two hydraulic drive systems.  When the equalizer valve senses a hydrostatic drive pressure difference be-tween the two drive systems, it readjusts the displacement of the pump having the higher pressure by lowering the hydrostatic pilot pressure to restore the balance of hydrostatic drive pressures.
