Patent EP-0416786-A2 (EP)
Inventor: DAWKINS GORDON MICHAEL
IPC: C08F10/00
Filed: 1990-08-23
Abstract: The present invention relates to an olefin polymerisation catalyst obtainable by depositing on a dry inorganic oxide support a mononuclear chromium complex which is a mixture of (A) a first mononuclear chromium complex represented by the general formula:
      wherein 
- three of R₁ to R₅ are H and the other two are H, or C₁-3 hydrocarbyl group, and 
- L is one or more hydrocarbyl ligands which are sufficiently reactive to enable the complex to react with the inorganic oxide without thermal activation, and 
(B) a second mononuclear chromium complex representable by the general formula:
      wherein 
- the cyclopentadienyl ligand is substituted with 4 or 5   hydrocarbyl groups (R1-R5) containing 1 to 3 carbon atoms, and 
- L has the same definition as above, being identical or different. 
     The catalyst can be used for polymerising olefins, particularly ethylene optionally with C₃-8 alpha-olefins. It can be thermally activated before use in olefin polymerisation. It produces polyolefins having a relatively broad molecular weight distribution, the breadth and shape of which being easily controlled.

Abstract: In a raster output scanner, a system is disclosed for using one original beam and one facet of a rotary prism to generate a scan line which can be made to have three levels of intensity. The original beam (20) is first separated into two parallel beams in a beam splitter (21). The resultant beams are polarized ninety degrees apart, and directed to a modulator (22). The beams are a sufficient distance apart for the modulator to modulate each beam with reduced or no crosstalk. The output beams are then brought together and combined into one beam without optical interference, because the beams are polarized ninety degrees apart. The output beam can have several levels of intensity and be used to create several levels of grey-scale.

Abstract: A motor-vehicle steering wheel which is made of plastics material but looks like a wooden steering wheel is produced from a die having ribs such as to form in the moulded part indentations having a typical wood-grain pattern and arrangement. In the moulded part, the plastics material used for the moulding assumes a density of the same order of magnitude as that of a typical wooden steering wheel. A dark-coloured ink is applied to the surface of the moulded part and penetrates the indentations to give them the wood-grain appearance, the ink subsequently being removed from the rest of the surface of the part and the part then undergoing a final varnishing step.

Abstract: Information carriers which contain an electrically erasable programmable memory (EEPROM) suffer from the problem that the utilisation period of the carrier is greatly restricted if data in a fixed address space of the EEPROM have to be changed frequently, since the service life of the individual cell of the EEPROM is limited by the number of its write cycles. By reducing the writing frequency, for example by introducing checking steps before the actual writing operation and selective writing dependent on the result of the check, the utilisation period of the information carrier can be prolonged.

Abstract: A chemical cartridge (1) for protective respiratory mask (2) comprising separate active filter section and universal filter section. The active filter section is formed of an absorbent medium impregnated with a reagent capable to capture and derive a target toxic pollutant having a chemically active function into an inert, non-volatile and non-toxic matter as air is inhaled. When air is inhaled by the user as indicated by the arrow (8), the flap (6) moves away from the disk section (5) to allow the inhaled air to pass through the perforations such as (9) of the latter section. When air is exhaled, the flap (6) comes into contact with the disk section (5) to prevent the exhaled air to penetrate the cartridge (1) through the perforations (9) ; migration of the pollutants captured in the cartridge (1) is thereby prevented to maintain the efficiency and safety of the chemical cartridge.

The first step comprises a run length algorithm to obtain an intermediate image with a linear reduction of twenty. In the second step blocks of pixels (1-9) of the intermediate image are replaced by single pixels in the reduced images (41, 42) to obtain a further linear reduction with a factor of three. The pixels in the reduced images are assigned a grey level in dependence of the distribution of black pixels in the block of pixels (1-9) in the intermediate image.

     Accordingly, at the time of saving data, the input password and the designated partial data are converted according to a predetermined procedure to generate a first code, and the first code is stored to correspond to the designated partial data; and at the time of reading the saved data, the input password and the designated partial data are converted according to the predetermined procedure to generate a second code, the generated second code is compared with the first code stored to correspond to the designated partial data, and a discrimination is made that the designated partial data has been unjustifiably reloaded if the comparison results in a fact that they are not the same. In a case where the designated partial data includes another partial data, the partial data is included in the target of the code generation, the partial data is omitted from the same or the content of the partial data is not included but only punctuation information is included.
