Abstract: ABSTRACT OF THE DISCLOSURE    A catalyst for the production of synthesis gas or hydrogen from aqueous methanol by dissociation or steam reforming.  The catalyst contains: A)   a metal component of one or more elements of the VIIIb group of the periodic table on a carrier material on the basis: B1)  of TiO2 or CeO2, singly or in admixture with other heat-resistant metal oxides and/or binders or B2)  of TiO2, which is introduced onto the surface of a pre-formed, heat-resistant carrier. Processes utilizing this catalyst allow for the dissociation of methanol for production of synthesis gas, or for the pro-duction of hydrogen through steam reforming.  Thus, the concentration of hydrogen or of carbon monoxide may be controlled by monitoring the concentration of steam utilized in the inlet feed.

Abstract: Abstract A vibratory apparatus is disclosed for scrub-bing, abrading, pulverizing, grinding, crushing, milling and/or separating granular material.  The apparatus in-cludes a two mass vibratory system with a tube, as part of the working mass, provided for the granular material and having an inlet end and an outlet end open to a stack at a location lower than the inlet end.  The stack has means  for creating  an upward  countercurrent  air  flow therethrough.   A  driving  mass,  including  a  vibration generating assembly, is provided for vibrating the driv-ing mass and the working mass so that the granular mater-ial is agitated in the tube at large accelerations to scrub, abrade, pulverize, grind, crush or mill the granu-lar material.  When the apparatus is used as a separator or classifier, the countercurrent air flow in the stack causes minute particles to move up through the stack to separate the minute particles from the batch of granular material as the material is discharged into the stack. A matrix or media, such as balls, may be located in the tube to crush, grind or mill the material passing through the tube to reduce the size of the material.  A method is also disclosed which includes the steps of feeding granu-lar material into a tube as described above, vibrating the tube to agitate the granular material, and creating a countercurrent air flow over the outlet end of the tube to move the minute particles away from the falling granu-lar material.

Abstract: "VISBREAKING PROCESS"     An improved visbreaking process having a lower utilities (heating fuel) cost is disclosed.  The feed stream is heated by in-direct heat exchange against the bottoms stream of a first fractiona-tion column, which receives the effluent of the visbreaking heater.          A portion of this bottoms stream is then used as quench.  This quench stream is hotter and has a higher flow rate than previous designs.     The feed is heated to a higher temperature by the indirect heat ex-change and therefore less fuel is required in the visbreaker fired heater.

Abstract: DUAL PURPOSE SCREEN/MEMORY REFRESH COUNTER                    Abstract A counter is used to concurrently refresh a video display and a memory associated with such video display.  Address bits are output from the counter to the sync decode logic used to refresh the display as well as to multiplexing means connected to the associated memory.  The multiplexing means has three pairs of inputs.  The first pair of inputs comprises refresh addresses from the counter for refreshing the memory array.  The second pair of inputs to the multiplexing means comprises memory update addresses for writing new information into the memory.  A third pair of inputs to the multiplexing means performs two functions. The first function enables the multiplex-ing means to output either the update addresses or the refresh addresses depending on the state of such inputs.  The second function of the third pair of inputs is to identify the output of said multiplexing means as either a row address or a column address to the associated memory.  The apparatus and technique disclosed herein is especially pertinent when a "nibble mode" dynamic RAM is used as the memory.

Abstract: ISDN D CHANNEL HANDLER Abstract of the Disclosure In an integrated services digital network (ISDN) a telephone subscriber is physically connected to a telephone exchange by a digital signal subscriber loop which provides in time division multiplex  (TDM),  two B channels and a D channel.  The two B channels are used for voice and data at a bit rate of sixty-four kilobits per second each.   The D channel is used for packet data and for telephone signalling and supervision at a bit rate of sixteen kilobits per second. An ISDN D channel handler, in an exchange termination (ET) collects D channel data from and distributes D channel data to various ISDN subscriber lines.  A frame processor, in the D channel  handler,  receives  D channel  information  as  it occurs in each of the receive channels.  It directs D channel data  to  a  receive  buffer  storage  location  where  it  is accessible  by  a  translator.    The  translator  recognizes information in the data which relates to supervisory and signalling functions, and passes the information to a central controller in the ET.   Likewise, signalling and supervisory information  destined  for  an  ISDN  subscriber  line  is translated  into  ISDN compatible  data which  is  stored  in transmit  buffer  storage  locations.    The  frame  processor subsequently pulls this data from the storage locations, and formats it according to CCITT standard, before transmitting it on  the appropriate transmit D channel of  the TDM bit stream to the subscriber.   Packet data received in the D channel is recognized after it has been stored in the receive buffer storage location and then is immediately queued for transmission  via  the  frame  processor  and  a  digital transmission link to a separate packet network.  Packet data from the separate packet network is received from the digital transmission  link and  stored via the  frame processor  in buffer storage locations.  Subsequently, the information bits of each stored data packet are formatted according to the CCITT standard by the frame processor, and transmitted to the intended subscriber on the appropriate D channel.                         - i -
