Patent EP-0173901-A3 (EP)
Title: Process to make small crystallites of zsm-5
IPC: B01J29/40
Filed: 1985-08-16
Abstract: ZSM-5 crystallites having dimensions below about 0.3 
micrometer are produced in the as synthesized form with 
very low levels of blocking tetrapropyl ammonium (Q) ions. 
The reaction mixture contains sources of silica, soda, 
alumina, a polyol such as ethylene glycol and trace amounts 
of Q ions as nucleation agents. Because the crystallites as 
synthesized from the aqueous medium exhibit only a small 
fraction of blocking cations, there is always a diffusion path 
for the hydrated sodium ions to be exchanged without the 
need of prior removal of the blocking cations by calcination 
or otherwise. The small size crystallites can be exchanged, 
blended with matrix material, and formed into catalyst 
particles. The silica to alumina ratio can be varied and when 
no aluminium is added, silicalite may be formed. The 
synthesis can be done in 24 hours or less.

Title: Method and apparatus for grinding the slide surface of skates
IPC: B24B9/04
Filed: 1985-08-23
Abstract: An automatic sharpening of the slide surface of a skate to desired profile with regard to at least two dimensions x and y in a coordinate system is disclosed. A grinding wheel (18, 119) is by guide means (14, 15) movable in x-direction in the longitudinal direction of the slide surface and by guide means (20, 11) movable in y-direction. Firstly, a scanning of the existing profile of the slide surface is carried out by means of the grinding wheel which with a substantially constant abutment pressure forceably is moved along the slide surface, during which movement the x- and y-coordinates of the profile are continuously recorded in a memory. After eventual correction of the coordinates in the memory the grinding is carried out by forcing the grinding wheel in rotating state to repeat the recorded coordinates upon impulses from the memory.

Title: Method of encoding n-bit information words into m-bit code words, apparatus for carrying out said method, method of decoding m-bit code words into n-bit information words, and apparatus for carrying out said method
IPC: H03M5/14
Filed: 1985-01-18
Abstract: A method of encoding n-bit information words into a m-bit code words and the other way round is described, which code words have a specific disparity d and a digital sum value which is limited to values p and q. In order to enable encoding and decoding without the use of an extensive look-up table use is made of a series of numbers which is a modified version of numbers in conformity with the Newton binomial. By means of this modified series the n-bit information words, which are arranged in conformity with their binary weights, are mapped lexicographically and unambiguously onto code words with limited digital sum value, and the other way round.

Title: Railway switch
IPC: E01B7/22
Filed: 1986-09-05
Abstract: A railway switch is mounted on y-shaped sleepers. All sleepers in the switch have a medium portion of equal slightly s-shaped configuration and length. The length of the straight and parallel ends depends on the position of the individual sleeper in the switch. The sleepers extend alternately from one outer rail in the direction to the other outer rail. The crossing piece is supported by y-shaped sleepers which underlie only the crossing piece and alternately one of the outer rails in the switch. If the switch comprises a straight and a curved line, all sleepers supporting the outer straight rail are arranged at a right angle to the straight line and protrude outwardly over the straight rail in the same length. Preferably the sleepers are composed of two s-shaped I-beam steel profiles and additional shorter I-beam steel profiles at the bifurcated straight ends, all pairs of adjacent I-beams being connected at a distance forming a slit for inserting a coach screw.

an electronic control device (53) - after a predetermined time during periods 
of prolonged continuous air loading from the compressor through the air drier 
even if said pressure is not reached.

vaporisation thereof during an operation mode of the 
apparatus is disclosed, which includes cooler means (3) 
for effecting cooling of the solvent in said container

heater means (3) of the heat pump as cooler means (3) 
during shut-down may be effected using values (2, 6, 10, 
11) which change the flow path of the heat transfer 
medium.

Abstract: Updated images of messages are passed between 
asynchronous digital processors using dual port shared 
memory. Where one of the processors is a controller for a 
datalink channel carrying n messages, 2n + 1 buffers are 
provided in free shared memory space with 2 buffers as­
signed to each message at all times and a common buffer 
serving as the third buffer for all of the messages. Where 
linked buffers in local memory of a controller processor 
receive message updates from a data highway, two buffers in 
shared memory are assigned to each message and a linked 
buffer in the controller local memory serves as the third 
buffer. The buffers containing the message updates are 
passed between processors by use of a buffer status array 
in shared memory. A semaphore lock in the array permits 
only one processor at a time to assign or release buffers.
Patent EP-0303479-A3 (EP)
Title: Method of preparing whiskers of silicon carbide and other materials
IPC: C30B25/00
Filed: 1988-08-11
Abstract: The invention relates to a method of producing 
whiskers of silicon carbide and other materials. For the 
formation of silicon carbide, the method involves forming 
a first reaction zone (23) containing microfine particles 
of silicon dioxide uniformly mixed with carbon or a carbon 
precursor, with the ratio of the silicon dioxide to the 
carbon present as a starting material or derivable from 
the precursor being greater than about 5 to 1 by weight. 
A closely adjacent second reaction zone (24) is formed 
containing a porous fibrous mass of active carbon or an 
infusible carbon precursor. The reaction zones (23, 24) 
are heated under a non-oxidizing atmosphere to 
temperatures at which silicon monoxide is formed in the 
first reaction zone (23), diffuses to the second reaction 
zone (24) and reacts with carbon derived from the carbon 
precursor in the second reaction zone (24) to form silicon 
carbide whiskers. A continuous supply of a 
whisker-forming catalyst is provided in the second reaction 
zone (24), at least in the vicinity where the silicon 
monoxide and carbon react with each other. This can be 
assured, for example, by providing the whisker-forming 
catalyst in the first reaction zone (23) together with a 
catalyst volatilizing aid which enables the catalyst to 
diffuse to the second reaction zone (24) along with the 
SiO. The first reaction zone (23) may also contain a 
catalyst for the SiO producting reaction. By changing the 
starting materials, reaction temperatures etc. but using 
the same method steps, whiskers of other materials such as 
AlN, sialons, Si₃N₄ etc. can also be prepared.

Abstract: The warp system comprises textile yarns (3a, 3b), which are 
preferably of a water-repellent synthetic material, and the weft 
system comprises at least an elastic, water-impermeable circular 
ribbon (1), such as a plastic or rubber circular ribbon. Thus 
water absorption is prevented in the mat, which does not feel wet. 
The mat is agreeable to stand on, owing to the elastic circular 
ribbon wefts, and the mat has an easy maintenance and dries rapidly. 
In addition to the circular ribbon wefts, the mat can 
comprise textile wefts, for example a ribbon and a textile yarn 
alternating in every second weft.  
     The borders of the mat in the direction of the weft are 
bordered with a cleaved plastic hose (4), which is fixed by a 
listing seam (5) and on the borders in the direction of the warp 
simply a listing seam (5) is provided.
