Abstract: ABSTRACT          A tap primarily  intended for  'bag-in-a-box' constructions including a plunger  (80)  which is in a barrel (52). A knob (68) is fast with the plunger (80) and  is arranged so that it and the plunger perform a spiral movement when it is rotated.  The tap includes a seat (66) with which a sealing portion (86) of the plunger (80) co-operates. The inlet to the barrel is through one end thereof and there is an outlet port (64) in the wall thereof.   The part of the plunger (80) outwardly of the sealing portion (86) constitutes a wiping edge which moves across the port (64) during opening and closing movement of the plunger (80).  A piercing element (94) is provided which, the first time the tap is opened and closed,  is forced through the hermetically sealed pouch (P).  The tap is leak-proof, does not permit air to enter the pouch P in normal  operation and,  because of the wiping action provided, does not drip.

Abstract: ABSTRACT     An addition agent and method are provided for adding alloying ingredients to a molten steel bath comprising a P/M compact formed of a compacted mixture of a particulate primary addition alloy and at least one secondary particulate metal.  The primary particulate addition alloy is formed of a plurality of elemental metals at least one of which is present in substantial amounts and which primary addition alloy when added to the steel bath alone has a dissolution rate in said bath characteristic of said primary alloy.  The at least one secondary particulate component is also an additive to said steel bath and is characterized by being exothermically reactable with said substantial amount of elemental metal in said primary addition alloy so that additional heat is generated when the P/M compact is added to the molten steel bath, whereby the dissolution rate of the primary addition alloy in the compact is substantially increased over the characteristic dissolution rate of the same primary addition alloy when added to the steel bath alone.

Abstract: A B S T R A C T      This sensor, which is of the oxygen pump type, makes it possible to generate an electric signal representative of the oxygen content of a gas, linearly dependent on this oxygen content, made of a solid electrolyte plate    , one of whose faces is partly covered by a ca-thode      impervious to oxygen to be brought into the presence of the said gas, and whose other face is covered by an anode     to be brought into the presence of a reference gas. Under the effect of the difference  in potential prevailing between the two electrodes , there appears at the surface of the solid electrolyte an area in which the molecular oxygen contained in the said gas is trans-formed into negative ions. The electrons captured by the oxygen dur-ing this transformation produce the said electric signal.

Abstract: FLUIDIZED CATALYTIC CRACKING PROCESS            ABSTRACT   The present invention involves an improved process and apparatus for the fluid catalytic cracking (FCC) of hydrocarbons.  In such an invention, the output of a reactor riser zone is fed to a riser cyclone separator, a primary cyclone separator, and secondary cyclone separators, connected in series within a single reactor vessel.  The riser cyclone separator is connected to the primary cyclone separator by a conduit, which prevents random post-riser thermal cracking of the hydrocarbons after they exit the riser cyclone separator.  An opening in the conduit is provided to allow stripping gas to enter the conduit. Catalyst separated in the riser cyclone separator can drop through a riser cyclone dipleg and can then pass through a dipleg seal which comprises a seal pot or catalyst held around the dipleg.  Steam may be directed into the riser cyclone separator to improve the separation of hydrocarbons from catalyst.

Abstract: ELECTROMAGNETIC ENERGY INTERFERENCE SEAL       FOR LIGHT BEAM TOUCH PANELS                   ABSTRACT An electromagnetic energy interference seal arrangement is provided for use in light beam touch panel systems.  The electromagnetic energy interference seal includes the use  of waveguides (40)  associated with  the light beam sources (34) and detectors (36) to improve light beam touch panel performance.  The waveguide size is selected so that it operates as a waveguide above cutoff frequency for the light beams (32) but operates as a waveguide   below    cutoff   frequency    for    blocking electromagnetic energy interference.  The waveguides (40) improve the light beam signal to noise ration since they shade the detectors (36) from reflections and from extraneous light such as from overhead room lighting. Bonding of part of the electromagnetic energy interference seal is effected by an electrically conductive compound which enables nondestructive disassembly when required. Environmental sealing strips (42,43) are provided to cover the waveguide apertures to protect against dust, liquids and other environmental contaminants.
