Patent EP-0285567-A2 (EP)
Inventor: RUCKSTUHL WILLI
IPC: E01C5/06
Filed: 1988-03-25
Abstract: The set of paving stones consists of stones (11-16) having in each case in plan view six lateral limiting faces (1-6, 17-22). Four of these limiting faces (1 and 4, 3 and 5; 18 and 21; 19 and 22) are each placed parallel to one another in pairs, whereas the remaining two (2 and 6; 17 and 20) together form an acute angle. The stones (11 - 13) are laid alternately in the straight line. This gives rise to a joint pattern with butt joints which are not perpendicular to the bedding joints. The butt joints are moreover formed from two mutually oriented wedges and are therefore irregular compared with the bedding joints. The bevelled limiting faces  (2, 6) make it possible for the stones (11 - 13), depending on the desired bevel angles, to be laid in curves whose radii can be as small as desired, the wedge-shaped joints gradually closing. The stones (14 - 16) serve as a supplementary curve set and permit the laying of Roman arrow patterns as well as an Archimedean spiral. The set of paving stones can be laid simply and quickly without a cutting of the stones.

Abstract: A photomask is made in contact with or approach a board to which a photosensitive material for a printed circuit is applied, and a clearance between the photomask and the board is filled up with a liquid such as water. The liquid, which has smaller difference in refractive index between the same and the photomask and the photosensitive material as compared with air, facilitates linearity of light. Thus, a pattern provided on the photomask can be reproduced on the photosensitive material, i.e., the board, in high fidelity.

Abstract: In optical receivers, a sensitivity control is frequently necessary to be able to emit the generated electrical signals in a comparatively small amplitude range despite widely varying received light intensities. In optical receivers with avalanche photodiodes, it is customary to control the input sensitivity via the multiplication factor of the avalanche photodiode, and in addition in correspondingly large input amplitude ranges it is customary to connect further controlled amplifiers downstream of the avalanche photodiode. The compensation and the optimisation of a plurality of control circuits coupled to one another is, however, difficult and costly so that in the optical receiver according to the invention an uncontrolled transimpedance amplifier with downstream uncontrolled limiter amplifier is provided and the control device contains an inverse PI controller which is dependent on the output signal of the limiter amplifier. <IMAGE>

Abstract: The modified rubber compositions comprise by weight about 15-60% of a highly saturated aliphatic rubber such as ethylene-propylene-diene rubber, about 25-80% of preferably non-nitrogenous acrylate monomer units; and less than about 5% multi-functional monomer units. The compositions exist as amorphous heterogeneously dispersed phases. The first phase comprises the copolymer rubber to which polymers of at least 10%, preferably 20%, and more preferably 30% of the other monomer units are grafted. The second phase comprises the other monomers polymerized as homo and copolymers, not grafted to the rubber. Greater than 10% and preferably 20% of the monomer units other than rubber are grafted to the rubber. The number average molecular weight of the grafts is between 10,000 and 80,000 daltons. 
     The modified rubber composition, additional, preferably non-nitrogenous, polyacrylate polymer, and another polymer are mixed together to form a polymer blend having higher impact strength and other important properties. The other polymers are often more expensive and usually have some advantageous property compared to polyacrylate. Other polymers disclosed are: polycarbonates, SAN, polystyrene, polyvinylchloride, polypropylene, polyester, styrene maleic anhydride, chlorinated polyethylene, polyethylene terephthalate, nylon and ABS. Polycarbonate blends preferably comprise a total of at least 35% and up to 65% polyacrylate.   The proportion of rubber used to form the graft rubber composition to the total graft rubber composition and polyacrylate polymer in polycarbonate blends is in the range of approximately 2 to less than 30% by weight and preferably no greater than 25%. 
     The modified rubber composition is present in polycarbonate blends in the range of approximately 6% to 50% by weight. The added polyacrylate preferably has a molecular weight greater than 80,000 daltons.
