Title: Cpu channel to control unit extender
Inventor: WALDRON BILLY B
IPC: G06F11/10
Filed: 1987-03-13
Granted: 1990-12-27
Abstract: CPU CHANNEL TO CONTROL UNIT EXTENDER      A  system  is  described with which  data  can be reliably transferred at high channel speeds between an IBM CPU channel  and a remotely located control unit through a high speed full duplex data link that can be a T3  speed telephone  line.  A pair of similar coupler units are provided, one of which is connected by way of conventional bus and tag cables to a channel and the other by such cables to the remotely located control unit. In one  embodiment,  the  coupler  units  have extended buffers  to enable retransmissions of entire data  blocks  in  case  of  error.   A  special  counter technique is  described whereby the transfer of fixed length data blocks for I/O devices such as printers can be  accommodated  without  creating  incorrect  length problems with the channel.  A high speed microprocessor is used to regulate the initialization and end sequences needed to establish communication between the channel and a control unit while a data transfer assist logic controls the transfer of data which is transmitted over the serial data link without interlock signals normally used between a channel and a control unit.  A data streaming mode is accommodated.

Title: Drilling boom
Inventor: FOSTER BRUCE A
IPC: E21B15/04
Filed: 1987-03-30
Granted: 1991-06-25
Abstract: ABSTRACT     A drilling boom has an articulated arm    which carries a drill feed beam    on its outer end.  Apart from the articulation        provided by the joint at the outer end of the arm,  the feed beam can rotate about two mutually perpendicular axes at the end of the arm.  One of these axes is defined by the so-called rollover unit and the other axis     is at right angles to the length of a drill rod on the feed beam and allows at least 180 degrees of rotation so that parallel holes can be drilled in all parts of the roof, floor and side walls of a heading.

Title: Addition of hydrogen to carbon monoxide feed gas in producing acetic acid by carbonylation of methanol
Inventor: TORRENCE G PAULL
IPC: C07C51/00
Filed: 1987-06-03
Granted: 1992-04-21
Abstract: ABSTRACT        The carbonylation of an alcohol to produce a carboxylic acid, especially methanol to produce acetic acid, in a low water reaction medium containing a rhodium catalyst stabilized with an iodide salt, especially lithium iodide, along with alkyl iodide such as methyl iodide and alkyl acetate such as methyl acetate in specified proportions is improved by the addition of hydrogen in the feed gas to the low water reaction medium to obtain a reactor hydrogen partial pressure of at least about 4 psi. The presence of hydrogen in the reaction medium increases significantly the carbonylation reaction rate and reduced formation of byproduct carbon dioxide.  The present reaction system not only provides an acid product of unusually low water content at unexpectedly favorable reaction rates but also, whether the water content is low or, as in the case of prior-art acetic acid technology, relatively high, is characterized by unexpectedly high catalyst stability; i.e., it is resistant to catalyst precipitation out of the reaction medium.
