Abstract: TITLE: HYDROGEN SUPPLY SYSTEM                     ABSTRACT       A system for supplying hydrogen to an apparatus which utilizes hydrogen, contains a metal hydride hydrogen supply component and a microcavity hydrogen storage hydrogen supply component which in tandem supply hydrogen for the apparatus.  The metal hydride hydrogen supply component includes a first storage tank filled with a composition which is capable of forming a metal hydride of such a, nature that the hydride will release hydrogen when heated but will absorb hydrogen when cooled.  This first storage tank is equipped with a heat exchanger for both adding heat to and extracting heat from the composition to regulate the absorption/deabsorption of hydrogen from the composition. The microcavity hydrogen storage hydrogen supply component include's a second tank containing the microcavity hydrogen supply.  The microcavity hydrogen storage contains hydrogen held under high pressure within individual microcavities.  The hydrogen is released from the microcavities by heating the cavities. This heating is accomplished by including within the tank for the microcavity hydrogen storage a heating element. Both the metal hydride hydrogen supply component and the microcavity hydrogen storage hydrogen component supply systems are connected to the hydrogen utilizing apparatus by suitable conduits which include gas flow valves for regulating the flow of hydrogen through the conduit.  An additional conduit supplies hydrogen from the microcavity hydrogen storage hydrogen supply component to the metal hydride hydrogen supply component for recharging the metal hydride hydrogen supply system.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a system to provide a controlled tem-perature mixing of two or more fluids by an immediate visual indication of necessity for particular adjustment and achievement of a predetermined fluid blend temperature range.  The device includes plumbing fixture apparatus comprising a pair of manually controlled hot and cold fluid mixing valves and an integral fluid flow activated temperature sensor with electronic trans-lation of fluid temperature imbalances between sensed blended fluid tempera-ture and predetermined temperature values.  A fluid temperature imbalance will cause illumination of a particular fluid control valve handle thereby indi-cating that corrective temperature control is necessary by manually adjusting the fluid control valves until the proper fluid blend temperature range is achieved.

Abstract: TITLE APPARATUS FOR SYNCHRONIZING SPEED AND ANGULAR         POSITION OF POWER-DRIVEN MACHINES    ABSTRACT OF THE INVENTION The invention provides a simple, yet highly accurate device for synchronizing the speeds of two power-driven machines having separate, variable speed power-drives.  A pair of shafts are re-spectively connected to the two machines and mounted in opposed concentric relationship for rotation in opposite directions at rates respectively proportional to the speed of rotation of the two machines.  A differential unit is connected between the two shafts, such unit having equal size input and output sun gears respectively connected to the shafts.  The planetary output of the differential unit is connected to a speed control element for at least one of the motors respectively driving the machines to vary the speed of such machine to bring it into rotational synchronization with the other machine.  In accordance with a modification of the invention, if angular synchronization is also desired, a one-way clutch is provided between one of the shafts and its respective machine which is disengageable by a minimal torque produced by a difference in the rotational speed of the two shafts, and re-engages only in a fixed angular posi-tion when the two shafts are again brought into rotational synchronization.

Abstract: Abstract of the Disclosure A syringe for dispensing medicaments includes a barrel with a discharge end and an open end for receiving a plunger.  The plunger has a head with engagement means for receiving a plunger seal.  The plunger seal is a tubular member which is severed along a generally longitudinal direction providing a slit which allows the seal to be expanded for fitting onto the plunger head.  Preferably the slit has an irregularity at the forward end which provides a locking configuration which prevents the seal from being twisted away from its normally tubular shape.  For metered dose application, the shank of the plunger may be threaded for the desired placement of a stop ring threaded on the shank.          In one form, the ring and barrel have interlocking means to prevent the ring from moving backward when pressure is applied to the plunger after the ring has reached the barrel.

Abstract: ABSTRACT OF THE DISCLOSURE:      A high speed bus structure is described which employs an ordinary flat ribbon cable.  ECL receivers are coupled to conductor pairs of the cable through resistors which change the capacitive load of the ECL receivers to a resistive load.          The receivers are coupled to the cable through a plurality of connectors having spaced-apart pins.  The pins in each connector engage less than all of the conductor pairs, thus a plurality of connectors are required to completely couple receivers to all the conductors in the cable.  This connector arrangement substantially reduces the parasitic capacitance loading on the cable.  The invented high speed bus is able to effectively function at 100 MHz with 80 feet of cable and with 16 receivers coupled to each conductor pair.

Abstract: Abstract of the Disclosure Disclosed is a method of treating hydroperoxide mixtures, which comprises bringing an oily hydroperoxide mixture containing (A) an aromatic hydroperoxide having a hydroperoxymethyl group directly bonded to the aromatic nucleus and (B) an aromatic hydroperoxide having a 2-hydroperoxy-2-propyl group bonded directly to the aromatic nucleus into contact with an aqueous alkali solution of pH 12 to 14, separating the aqueous phase from the oil phase and decomposing at least a part of the component (A) extracted in the aqueous phase at a temperature higher than that of the contact.  According to this method, the starting oily hydroperoxide mixture can be converted to a mixture in which the primary hydroperoxide content is reduced without substantial loss of the tertiary hydroperoxide.  Therefore, aromatic hydroperoxide mixtures suitable for production of phenols can advantageously be proceeded.
