Patent EP-0241989-A3 (EP)
IPC: G06T9/00
Filed: 1987-04-06
Abstract: Pixel information representing an image for display is encoded 
using data compression into display data which can be stored on a 
compact disc. The data compression consists in obtaining the pixel 
information as a first matrix of high resolution pixel values, 
subtracting from this first matrix a second matrix composed of 
lower resolution pixel values, produced by low pass filtering the 
first matrix, to produce a third matrix of difference values, 
decimation filtering the second matrix to produce a fourth matrix 
of less density lower resolution pixel values and encoding the 
third and fourth matrices. The complementary decoding to obtain 
the original data consists in restituting the second matrix by 
interpolation filtering the coded fourth matrix, and combining the 
restituted second matrix with decoded third matrix. The coding of 
the third matrix takes into account rate of change pixel value 
information obtained by delta coding the fourth matrix and the 
decoding of the third matrix takes into account equivalent rate of 
change pixel information available at the interpolation filtering. 
Figures 1 and 2 illustrate the coding and decoding methods.

Abstract: A system for Write Once Read Many (WORM) optical 
storage devices to appear rewritable used magnetic disk 
storage and optical WORM storage subsystem. All new 
write operations are made to a magnetic cache storage 
(28) which resides on the magnetic disk subsystem. A 
Least Recently Written (LRW) technique is used to 
determine which valid data in cache storage is the 
oldest, and this is transferred to the WORM storage 
(30) when room for new data is required. In this 
manner all new write operations are performed to the 
magnetic cache storage and only the oldest valid data 
is transferred to WORM storage optimizing its use.

Title: Data link controller
IPC: H04L29/08
Filed: 1988-03-25
Abstract: A bidirectional serial bus port (104) can 
receive and transmit multiplexed and non-multiplexed 
serial data. In the multiplexed mode, data in one of up 
to thirty-one selectable time slots is received. One of 
the time slots can be selected which allows a lengthened 
contiguous number of bits to be received or transmitted, 
effectively increasing the reception or transmission 
rate. Control of the mode of operation of the DLC is 
provided by various user-accessible Status and Control 
Registers (112,212). Particular registers have bit 
positions monitoring status conditions in such a manner 
that the most-probable one of a set of conditions 
occupies the least-significant bit position, while the 
least-probable condition occupies the most-significant 
bit position. This affords simple shift and test 
technique for monitoring status conditions.

Patent EP-0297750-A3 (EP)
IPC: C10G35/06
Filed: 1988-06-14
Abstract: A process is described for the regeneration and reactivation of 
coked iridium-containing catalysts, and chemical modification and 
passivation of iron scale carried over from a ferrous metal regeneration 
circuit to the catalyst-containing reactor, or reactors, to suppress 
reaction between the iron scale and catalyst as normally occurs when iron 
scale contacts the catalyst of a reactor, or reactors. The iron scale is 
rendered non-reactive or inert in the reactor environment by converting 
the iron scale to a passive form, preferably ferric oxide, by employing 
ab initio an extended low temperature primary burn while purging the 
system of carbon oxides, notably carbon monoxide and carbon dioxide. 
Thereafter, the agglomerated metal, or metals, component of the catalyst 
is redispersed at conditions insufficient to reduce the oxidized iron 
scale which is contained in admixture with the regenerated catalyst. The 
agglomerated metal, or metals, component of the regenerated catalyst 
contained in admixture with the passivated iron scale is redispersed in a 
non-reducing atmostphere to return the catalyst to its active state 
without reduction of the passivated iron scale. This process is an 
improvement in those described in US-A-4,514,284 and US-A-4,517,076 
respectively.

Title: Method of making high melting point alloys
IPC: C22C33/04
Filed: 1988-08-04
Abstract: A method of making high melting point alloys. The reactive 
and non-reactive charge materials are separately refined as ini­
tial alloys, generally as an alloy of a base element selected 
from the iron group of the Periodic Table, such as nickel, and at 
least one metallic element other than the base element. At least 
one first initial alloy and at least one second initial alloy are 
provided. The metallic elements other than the base element in 
the first initial alloys are relatively non-reactive in the mol­
ten state, whereas the metallic elements in the second initial 
alloys are relatively reactive in the molten state. Amounts of 
the first and second initial alloys are selected to yield a pre­
determined composition of the high melting point alloy upon 
melting. The selected amounts are melted to form a molten mix­
ture having the predetermined composition, and then the molten 
mixture is solidified.

Title: Touchless proximity switch for railway installations
IPC: H03K17/945
Filed: 1989-05-16
Abstract: A contactless proximity switch remotely fed via a two-wire line should also properly signal inferences of very short duration by means of current pulses of a predetermined minimum duration with little current consumption. The contactless proximity switch consists of a sensor (SR), the electrical behaviour of which can be influenced by metal parts and the sensor voltage (US) of which, which can be changed when influenced, controls an electronic threshold switch (OP) which also emits pulses of a predetermined minimum length (t2/t4) with influences of only very short duration due to a special external circuit (C1, R4, D2). The contactless proximity switch is advantageously used as wheel sensor in railway signal systems in which high travelling speeds must be expected. <IMAGE>
