Title: L-aspartyl-l-phenylalanine derivative and a process for preparing the same
IPC: C07K5/097
Filed: 1988-10-19
Abstract: There is disclosed a novel L-aspartyl-L-phenylalanine 
derivative of the formula I 
  
wherein R is hydrogen or CH₃CO and R₁ is hydrogen or methyl, 
and pharmaceutically acceptable salts thereof. It is prepared 
in such a way that a compound of the formula II 
  
is condensed with an activated form of an acid of the formula III 
  
in a water-immiscible solvent such as methylene chloride 
in the temperature range from -20° to 0°C, optionally the 
obtained compound of the formula I, wherein R represents a 
CH₃CO group and R₁ represents a methyl group, is converted 
into the compound of the formula I, wherein R and R₁ represent 
a hydrogen atom, and then it is optionally converted into 
pharmaceutically acceptable salts thereof. 
 
  
     The compound of the formula I inhibits the conversion of 
angiotensine 1 into angiotensine 2, which plays an important 
role in regulating blood pressure.
Patent EP-0328781-A3 (EP)
Title: A velocimeter for a printing press web
IPC: B65H18/08
Filed: 1988-12-23
Abstract: A velocimeter and a method for measuring the velocity of a 
printing press web are provided. The velocity is measured without 
contacting the web by measuring a speckle pattern which is reflected off 
the moving web by a laser. The reflected light is filtered and detected 
by a linear photodetector array which is differentially connected. The 
photodetector array output is fed into a differential amplifier to 
obtain a differenced output which has a frequency that is related to the 
velocity of the web. The difference output is filtered through a 
variable filter set at a predetermined bandpass center frequency and 
bandwidth, and its frequency is counted to obtain the approximate 
velocity of the web. Using the approximate velocity, a bandpass center 
frequency and bandwidth is selected which provides a substantially 
linear response of velocity at the counted frequency. The variable 
filter is reset to the selected bandpass center frequency and bandpass, 
and the frequency of its output is obtained. The web velocity is then 
determined using a predetermined relationship between web velocity and 
frequency for the selected filter setting.

IPC: C10G11/18
Filed: 1988-01-08
Abstract: A process and apparatus for fluid catalytic cracking (FCC) 
of a hydrocarbon feed. The process and apparatus includes a riser 
which upwardly discharges into a deflector baffle located within a 
stripping vessel. The stripping vessel is located within a 
disengaging vessel. The deflector baffle is spaced from the riser 
and the stripping vessel. Preferably, the deflector baffle is 
shaped similarly to a large bubble cap. Catalyst passes downwardly 
from the baffle into a stripping zone within a lower portion of the 
stripping vessel. Hydrocarbons stripped from the catalyst pass 
upwardly away from the stripping zone, then pass to a cyclone 
located outside the stipping vessel and then discharge from the 
disengaging vessel.

Title: Method of operating a multiprocessor system employing a shared virtual memory
IPC: G06F15/177
Filed: 1988-11-09
Abstract: A method for maintaining the overall system availability of a 
multi-processor data processing system in the event of a failure at one of a 
plurality of independent failure points. The system includes a plurality of 
virtual memory type processor units, each of which includes an interactive 
terminal, and a main memory which is connected to a secondary storage device 
which is also shared by the main memory of one of the other processor units. 
The main memories of the two units are also interconnected to provide a 
shared virtual memory system. Both processor units employ the same operating 
system and share the same virtual address space for storing information. The 
interactive terminal of each processor unit is connected to the other 
processor unit. Failure points include the terminals, the processor units, 
the communication links, and the various software components that are 
employed by the system. System availability is maintained by managing the 
storage of selected information at pre-established precise points in the 
processing operation. Identical operating system data structures that are 
stored in each processor unit are updated with the results of certain 
identified data processing transactions which have affected information 
required for succeeding processing operations in manner to insure that 
either identical updates occur or no update occurs. The arrangement ensures 
that any changes that might have occurred in the information stored in the 
data structure prior to the end of an aborted transaction is returned to the 
initial state to permit the transaction to be retried whenever the path of 
the failure can be bypassed.

Filed: 1989-03-14
Abstract: Speech for transmission over a low bit rate channel of a 
telecommunications link is digitally sampled and 
subjected to linear predictive coding in a coder (6). 
The LPC residual signal is passed through a weighting 
filter (18) and the output down sampled by decimation 
factor  d  resulting in  d  sequences of which the maximum 
energy sequence is selected for vector quantization. 
The data output from the vector quantizer (22) is formed 
into an output frame together with an index ( s ) 
identifying the selected decimation sequence and the 
quantized LPC parameters. The frame transmitted over 
the telecommunications link (46) is decoded by means of 
an inverse vector quantizer (50) which restores the 
decimated sequence. An interpolator (52) interpolates 
zeros to restore an excitation signal for an LPC 
synthesis filter (54) from which the voice signal can be 
reconstructed.
