Abstract: BIPOLAR DRIVER WITH ILLEGAL CODE DETECTOR                   ABSTRACT OF THE DISCLOSURE    A bipolar driver controls the operation of a reversible polar-ity load such as a motor.  The driver links one    terminal of the motor with either a positive or a negative potential power supply in response to processor command signals comprising a combination of logic levels appearing at a pair of driver input lines.  The input lines are monitored to detect the presence of an illegal code combination which would otherwise function to simultaneously interconnect the load terminal with both positive and negative power supplies.  The load terminal is linked to the power supplies by a separate power transistor for each power supply.  Each power transistor is biased into conduction through a drive transistor. Upon detection of an illegal code, monitoring logic generates a signal which interrupts the emitter circuit of each of the drive transistors to inhibit both power transistors.

Abstract: ABSTRACT OF THE DISCLOSURE            A molecular glass based upon a phosphate of aluminum, or other trivalent metal, provides significant improvement over prior art glasses for encapsulation of high level radioactive nuclear waste.  When continuing a controlled amount of those elemental oxides found in a typical nuclear waste, the waste-glass would not devitrify under conditions which produced devitrification in the non-nuclear-waste-containing glass, exhibited hydrolysis losses lower by an order of magnitude, had high solvency power for those elemental oxides, exhibited little tendency for internal crystallite formation, and possessed other desirable physical characteristics, all in direct antithesis to the properties of the best prior-known glasses used for this application.

Abstract: PROCESS AND APPARATUS FOR MAXIMIZING OIL YIELD          IN THE RETORTING OF OIL SHALE            Abstract of the Disclosure An  improved apparatus  and method  for  the operation  thereof  for  retorting  oil  shale  with heat-carrying bodies wherein oil recovery is maximized.            After retorting, the spent oil shale and heat-carrying bodies are steam stripped within the retorting vessel to  maximize  the  amount -of  oil-containing  vapors delivered  to  the  recovery  apparatus.   The  stripped heat-carrying bodies and spent shale are then returned to a reheating vessel'.  The reheating vessel contains a dense phase  fluidized  bed  wherein  the  fixed  carbon contained -in the stripped spent shale is combusted to reheat the heat-carrying  bodies, the hot  flue gases simultaneously elutriating  fines contained within the mixture.    The  reheated  heat-carrying  particles  and spent shale particles are  steam stripped within the ccmbustion vessel to remove trapped flue gases before being  returned   to   the   retort  vessel  whereby contamination thereof  is prevented.   heat  from flue gases, excess spent shale particles, and removed shale ash and fines is used to generate the steam employed in the   stripping   operations   to  maximize   energy utilization.   The  invention  is based on the  finding that the decomposition of kerogen, which is present as a binder  in  raw  oil  shale,  leaves  pores  within kerogen-rich shale which results in relatively large surface areas.  Attrition o' the kerogen-rich shale in a fluidized bed operation at a superficial gas velocity of 7-14 ft/sec reduces the size of this porous, friable material and allows it to be removed in the exit gas stream.  The larger particles remaining oriqinated as kerogen-lean shale and thus lack the surface area and resulting sorption capacity to adversely effect retorting. The recycled  particles  thus  become effective heat-carryinq bodies. Recovery of sensible heat from the spent shale particles is accomplished in two fluidized  bed coolers to maximize heat transfer and energy utilization.

Abstract: Abstract of the Disclosure A seamless aluminum container of the type used for beer, soft drinks, edible goods or the like is provided which container is adapted to be manually axially collapsed to a smaller size when its contents are exhausted, the container collapse being accomplished without the need of any apparatus for guiding the container sidewall collapse and without the aid of any mechanical or fluid pressure device.  The container sidewall is shaped to provide a number of similar annuli each of concave axial cross section, adjacent annuli being sepa-rated by a peripheral, outwardly angled ridge.   Manual axial forces collapse adjacent annuli about an interposed ridge to form a collapsed container approximately one-fifth the size of the original container.   The device encourages consumers to recycle aluminum, facilitates the storage and transport of aluminum cans to a recycling station, strengthens aluminum cans in a transverse direction permitting thinner aluminum stock to be used, and conserves aluminum and the energy needed to produce aluminum.

Abstract: ABSTRACT    During the continuous casting of preforms of large cross-section, considerable problems occur in the straightening region, because due to straightening, deformations are caused in the billet which has not yet solidified at the core.  Therefore, in addition to the upper and lower straightening rollers additional lateral support rollers are provided, so that the billet is supported on all sides.  For the purpose of space-saving incorporation in a multi billet installation, the support rollers are mounted in swinging frames, which are moved by vertically raised cylinders.  In order that the support rollers can be adapted to different billet dimensions, they are received within the fork like swinging frames by vertically movable guide frames with roller supports inserted therein and able to be adjusted horizontally.  Springs inserted in the swinging frames exert a continuous force in a vertical direction against the guide frames.  Upon lowing of the upper straightening rollers, the pressure plates of the roller supporting beam bear against the guide frames, whereby an automatic adaptation to a new billet thickness is provided.
