Abstract: METHOD FOR LOADING OR UNLOADING FROM A VEHICLE A                   STORAGE APPARATUS.                  ABSTRACT OF THE DISCLOSURE.            A method for loading on a vehicle provided with a pivotable handling arm or for unloading from the vehicle, a storage apparatus, such as a silo or tank, which may be inclined between an operative position in which a reference plane of the apparatus is roughly vertical and in which the apparatus may have its own stability on the ground, and a transport position in which the apparatus rests on the vehicle.  The apparatus includes front support means which bear on the ground in said operative position and which are withdrawn for loading the apparatus, so that the apparatus is then, under the effect of the force of gravity, able to bear on the end of  the handling arm and is free to be inclined toward the vehicle under the action of the handling arm, while retaining, for an angle of inclination to the vertical of said reference plane less than a limit value a, a supporting contact with the ground through fixed support means.  The apparatus is, for an angle of inclination exceeding a, either raised from the ground in a position in which the lower part of the apparatus is supported on the rear part of the vehicle or completely supported on the top of the vehicle in the loaded and transport position.

Abstract: ABSTRACT OF THE INVENTION             Novel membrane compositions are prepared from polymers comprising tertiary amine containing polyamideamine functional groups.  The membranes are durable, highly sel-ective and have excellent homogeneity and high diffusivity. Asymmetric membranes can be prepared by solution casting or melt processing techniques can be used to produce homogeneous, high performance, symmetric membranes.  The specific composi-tions of the membranes can be adjusted so as to achieve a membrane possessing a ?ired degree of hydrophilicity and porosity. These membranes may be used in a variety of separa-tion applications, particularly in two-phase solvent extraction.

Abstract: METHOD AND SYSTEM FOR REGENERATING               FLUIDIZABLE CATALYST PARTICLES                         ABSTRACT           A hydrocarbon conversion-catalyst regeneration operation is described which relies upon an upflowing fluid catalyst mass of decreasing particle density superimposed by an upflowing dispersed catalyst phase undergoing catalyst regeneration to effect elevated temperature regeneration of catalyst deactivated by hydrocarbonaceous material under conditions providing CO levels less than 0.15 mol percent in the flue gas.  Regenerated catalyst is mixed with spent catalyst in a first contact zone to obtain an initial mix temperature of at least 1175°F. before contact with a second-ary oxygen containing regeneration gas stream as a part of the upflowing fluid catalyst mass.  The ratio of hot regenerated catalyst to spent catalyst is restricted to obtain a mix temperature particularly promoting the combustion of hydro-carbonaceous material with oxygen containing gas in the up-flowing dense and dispersed catalyst phase so as to provide a discharged dispersed catalyst phase temperature of at least 1350°F.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an insulation system for use in rocket motors containing solid composite propellants.  Some composite rocket propellants are based on carboxyl-terminated polybutadiene (CIPB) and others on hydroxyl-terminated polybutyadiene (HIPB) binders.  An important requirement of such systems is the ability of the wall insulation to adhere to the combustion chamber and of the composite propellant to adequately adhere to the insulation system.  With CIPB propellants, a sheet insulant comprising chrysotile asbestos fibres and floats dispersed in a CIPB polymeric binder has been successfully employed.  However, the use of a similar sheet insulant based on HIPB polymeric binder has not proved to be compatible with HIPB propellants.  The present invention provides a composite sheet insulation system which is compatible with HIPB propellants and which comprises a first layer of a sheet material comprising a CIPB binder having a mixture of asbestos fibres and floats dispersed therein and, bonded thereto, a second layer of aluminumfoil.  The invention also comprises an economical and effective method of lining a rocket casing propellant chamber, using the novel system of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE         A hydraulic brake booster is disclosed which is normally actu-ated by a primary pressure source, but which may be actuated by a second-ary pressure source during failure of the primary pressure source.  The booster includes a spool valve which controls communication between the primary pressure source and the booster pressure chamber.  The spool valve is actuated by a control pressure which is generated by the vehicle operator when a brake application is effected.  The control pressure shifts the spool valve to cause the latter to communicate fluid pressure from the primary pressure source into the pressure chamber. A pressure differential responsive piston is responsive to a pressure differential between the control pressure and the pressure communicated into the booster pressure chamber.  When the control pressure exceeds the pressure communicated to the booster pressure chamber by some predeter-mined amount, the differential pressure responsive piston shifts to actuate a valve mechanism to communicate fluid from the secondary pressure source to the booster pressure chamber.  Simultaneously, shifting of the differential pressure responsive piston to actuate the valving mechanism also terminates communication between the spool valve and the booster pres-sure chamber, so that fluid pressure from the secondary pressure source communicated into the booster pressure chamber may not leak through the spool valve.

Abstract: READ ONLY MEMORY            Abstract of the Disclosure A read only memory is organized as a matrix of field effect transistors wherein logic levels are determined by the presence or absence of a gate which permits transis-tor action.  The memory is addressed using a gate decode tree which selects the gates of a column of matrix devices and a source decode tree which selects the source lines of a row of matrix devices.  Sensing of the logic level at a selected location is accomplished by a change of state output sense circuit which dymanically senses and provides a static output using a polarity hold circuit.  Clamped, boot-strapped inverter circuits are provided in both input and output circuitry to maintain voltage, at selected inter-nal nodes at a voltage intermediate predetermined minimum and maximum values.

Abstract: ABSTRACT OF THE DISCLOSURE:   A process for making a multi-core, fluid impregnated electric, submarine cable of long length in which each core is separately formed, impregnated and sheathed before the so-formed units are combined within an arms layer which is covered by a bituminous material.   Each unit is formed by forming a conductor of long length having an oil conduit therein.          The conductor is covered by paper tape insulation layers, conductive screening layers optionally being applied be-fore and after the covering of the conductor by the paper tape.   The so-formed core is then vacuum treated and impregnated with insulating oil, covered with a fluid impermeable sheath Which is then protected by blindage of metal tape.   Over the blindage, a plastics sheath is formed, and the so-formed unit is combined with similar units which are covered by the armor layer of metal and the layer of bituminous material.   The spaces between units and between the units and the armor layer may be filled with a filler material.   Also, a cable produced by such process.

Abstract: ABSTRACT OF THE DISCLOSURE:        A continuous casting apparatus comprising a casting vessel having a closable pouring opening for pouring metal through a protective tube into a flow-through vessel arranged beneath the pouring opening and into which vessel the outlet end of the protective tube extends, and means for changing the protective tube.  The tube is movable along guide means and between a sub-stantially horizontal position removed from the pouring opening and a vertical position beneath the pouring opening.  The guide means define paths of movement of the inlet end and the outlet end of the tube between the two positions such that the inlet end moves along a substantially horizontal path and the outlet end moves along a substantially vertical path within the flow-through vessel.  This apparatus enables the protective tube to be introduced into and removed from the casting vessel without the need for raising and lowering the casting vessel.
