Patent EP-0274833-A3 (EP)
IPC: F02C9/36
Filed: 1987-11-20
Abstract: An output member (15) is positioned by a servo pressure 
derived from between two variable fluid flow 
restrictors (18, 19) connected in series between a high 
pressure (HP) and a low pressure (LP). The flow area 
of a first restrictor (19) is variable by an input 
quantity to which the output member (15) is required to 
respond and the flow area of a second restrictor (18) 
is varied by movement of said output member (15) to 
change the servo pressure in a sense to oppose movement 
of the output member (15). In one embodiment the 
output member (15) incorporates a control element (20, 
22) for the second restrictor (18).
Patent EP-0274378-A3 (EP)
IPC: G11C29/04
Filed: 1988-01-05
Abstract: In a semiconductor memory device with normal word lines 
and spare word lines, a partial decoder (PD1 - PD4) receives and 
decodes a predetermined two of the bit signals of the original logic 
levels of an address signal, and two of the bit signals of the 
complementary logic levels, which correspond to the predetermined two 
bit signals, and outputs different signal combinations of the 
predetermined two bit signals and the two corresponding bit signals. A 
spare word line selecting circuit (SC1 - SC4) receives the different 
signals and selects one of the different signals in order to select a 
spare word line which corresponds to a normal word line of which a 
defective cell is connected. The partial decoder may be used for both 
the normal word line selection and the selection of spare word lines. 
With a device constructed in such a manner, bit signals of an address 
signal are not directly input to the spare word line selecting 
circuit, but rather signals of different bit signal combinations are 
input to it. The spare word line selecting circuit merely selects 
signals of different combinations, and does not need the partial 
decoding of the address signal. Therefore, the chip area required for 
wiring may be remarkably reduced when compared with the conventional 
memory device.

Title: Photosensitive cuprous halide materials and methods for their preparation
IPC: G03C1/725
Filed: 1988-09-05
Abstract: Photosensitive cuprous halide-type materials, 
particularly cuprous chloride and cuprous bromide materials, can 
be prepared from an anode product material produced from 
electrolysis of copper in an aqueous acid halide bath. 
Preferably, the copper electrolysis is carried out in a dilute 
hydrochloric acid solution. The resulting anode product 
materials are particularly sensitive in the presence of a polar 
molecule catalyst such as water or ammonia. In one highly 
preferred embodiment of this invention the anode product material 
is treated with the aqueous solution of ammonium salt of a water 
soluble organic acid (e.g. aqueous solution of ammonium 
ascorbate); one of the chief advantages of these materials is 
that they are highly photosensitive when dry and can be developed 
from a latent image prepared thereon.
Patent EP-0311906-A3 (EP)
Title: Aqueous dispersions of polyacrylates or polyacrylates emulsions, coating compositions containing them, process for their preparation and their use
IPC: C08F220/12
Filed: 1988-10-06
Abstract: Conventional concentrated solvent-free aqueous polyacrylate dispersions or polyacrylate emulsions generally have a highly acidic pH of from 2 to 3.5, which means that they have highly corrosive properties on the metal objects to be protected. By contrast, the novel polyacrylate dispersions and the coating compositions containing them have only a slightly acidic pH of from 4 to 6. The polyacrylate dispersions having the above slightly acidic pH are obtained by neutralising from 5 to 50 mol % of the carboxyl-carrying comonomers by means of a base before the copolymerisation with hydrophobic comonomers. The resultant polyacrylate dispersions dry on objects to give clear water-resistant films which can easily be removed using alkaline agents. Their pH of from 4 to 6 means that they are significantly less corrosive towards the objects to be protected. The aqueous polyacrylate dispersions or polyacrylate emulsions are used as coating compositions for temporary surface-protection of metallic and/or painted surfaces, in particular automobile bodies, against climatic and/or mechanical influences.

Title: Process and apparatus for obtaining vegetable fats and oils from oleaginous natural substances
IPC: C11B1/10
Filed: 1988-10-07
Abstract: The object of the invention is to improve the economics of processes for obtaining fats and oils, particularly continuous combined pressing and extraction processes, and simultaneously to ensure a high quality of the end product for different types of natural substances. To achieve this, natural substances, which may be pre-comminuted and conditioned, after pre-mixing with partially charged solvent phase, are subjected to an intensive treatment, mixing and extraction in the shear field of at least one rotor-stator machine, and subsequently the liquid phase is passed to a distillation column, optionally via a filter. The solid phase is extracted in subsequent steps to a residual oil content of < 1% and the solvent is recycled to the solid in countercurrent. The process according to the invention is employed for obtaining fats and oils from all fat- and oil-containing natural substances, using appropriate liquid extractants.

variation in amplitude of the received signals than can be compensated 
by control of the gains of the r.f. and i.f. amplification stages.

Title: Methods of encoding and storing pixel values and apparatuses for decoding and reproducing a digitised image
IPC: H04N7/46
Filed: 1989-12-18
Abstract: A method of processing a first series of values representing a row of pixels of a digitised image comprises:   (i) differentially encoding the first series of pixel values to generate a first series of codes (70) representing a first series of differential values; (ii) expanding each code (70) of the first series into a group of codes to form a second series of codes, each group of codes representing a plurality (72,74) of differential values whose sum is the differential value represented by the corresponding code (70) of the first series; and (iii) decoding the second series of codes to generate a second series of pixel values for display.   By transmitting or recording the first series of codes and then effectively dividing each received or reproduced differential value into two or more smaller differential values, known apparatus can be made with little modification to expand each line of a received image by a factor of two or more, depending on the number of codes in each group. The extra pixel values generated will be at least approximately linearly interpolated values. This allows improved moving pictures to be reproduced from an optical disc, for example.
