Title: Installation for ultrasonic dimensional treatment
IPC: B24B41/02
Filed: 1989-08-03
Abstract: An apparatus for ultrasonic dimensional treatment is 
designed for processing a workpiece of mono- and 
polycrystals. It comprises a frame of protal type (1), 
longitudinal (3) and transversal (2) displacement 
carriages, an acoustic head (4), a replaceable doser. 
The installtaion is also provided with a mechanism of 
setting displacements (6) along three coordinates, a 
telecamera with a set of elongating rings (7). It also 
comprises an electrical cabinet with an ultrasonic 
generator (9) and an apparatus of program control. A 
monitor unit is mounted on a rotary bracket. A 
mechanism for setting a clamping force (Fig. 2) ensures 
the necessary clamping force of a roller support (12) to 
be applied to a projection of a working table (15). 
Position of the pressure roller (16) is determined by 
the displacement of a movable carrier (20) being rigidly 
coupled with a gear rack (21) which engages a gear wheel 
(22) being mounted on a shaft of a reducer (23); the 
reducer being driven by a step electric motor (24). A 
calibrating weight (25) on a lever-rocker (13) is 
designated for selecting optimum operating conditions. 
A mechanism for feeding the working table ensures its 
rising by means of a lever (26) abutting a shaft (27) of 
a one-step reducer (28) driven by an additional step 
motor (29).

Abstract: An efficient, multistep process for the synthesis of certain 6-(1-hydroxyethyl) 2-substituted penem antibiotics from 2-[4R-(triphenylmethylthio)-3S-(1R-(dimethyl-t-butyl silyloxy)ethyl)-2-azetidon-1-yl]acetic acid esters.
Patent EP-0375188-A3 (EP)
IPC: G06F17/30
Filed: 1989-11-30
Abstract: A disc file system is described in which the 
disc space is divided into very large blocks of at least 
64Kbytes. A large file is allocated a whole number of 
these large blocks, contiguously where possible. Small 
files reside in small file areas each of which is 
composed of a number of large blocks. Space in these 
small file areas is allocated in multiples of a small 
block size (e.g. 4Kbytes).  
     The use of large and small blocks reduces the 
wastage of space that would occur if small files were 
written into large blocks. The amount of head movement 
when reading large amounts of data from large files is 
reduced because of the large block size and because the 
large blocks are allocated contiguously.

Title: Method of manufacturing an optical fibre having a hermetic coating
IPC: C03C25/106
Filed: 1990-04-12
Abstract: An optical fibre is provided with a hermetic coating of 
carbon by bringing the optical fibre into contact with a carbon-­
containing gas in a reactor at a high temperature immediately after the 
optical fibre has been drawn from a preform. To ensure that an 
amorphous carbon layer having a high hermeticity is formed on the 
fibrel the fibre is brought into contact with the carbon-containing gas 
at a location where the temperature of the fibre is 1100 to 1500 o C. 
To preclude carbon from being deposited on the wall of the reactor the 
temperature of said reactor wall is less than 800 o .

Title: Method and apparatus for increasing the data storage rate of a computer system
IPC: G06F12/08
Filed: 1990-01-12
Abstract: In a computer system, the flow of data from an 
execution unit (20) to a cache (28) is enhanced by 
pairing individual, sequential longword write 
operations into a simultaneous quadword write 
operation. A primary and secondary write buffer (50 
52) sequentially receive the individual longwords 
during first and second clock cycles and simultaneously 
present the individual longwords over a quadword wide 
bus to the cache (28). During the first clock cycle, 
when the cache (28) is not performing the quadword 
write operation, it is free to perform the requisite 
lookup routine on the address of the first longword of 
data to determine if the quadword of address space is 
available in the cache. Thus, the flow of data to the 
cache 28 is maximised.

Abstract: The invention relates to a superconducting connection of the filaments of an Nb3Sn and an NbTi conductor to a block made of pressed Nb- and Sn-containing powder which has been subjected to a reaction annealing, in which the filaments of the Nb3Sn conductor are embedded and on whose surface the filaments of the NbTi conductor are mounted, and to a method for manufacturing such a connection. The object of the invention is to propose a simple method for manufacturing such a superconducting connection with a current carrying capacity of > 200 A at 3 T and to propose a superconducting connection. According to the invention, the object is achieved in that a pressed-on layer of a deformable metal is connected to the block and the filaments of the NbTi conductor mounted on its surface in such a way that the block, the filaments of the NbTi conductor and the layer of the metal form a firm connection. The essential steps in the method for manufacturing this connection relate to the use of a CuSn foil which is pressed onto the block before the reaction annealing, and the pressing-on of a metal die which enters into a firm connection to the block and the intervening NbTi filament after the reaction annealing.
