Title: A Pump-and-Valve Arrangement for Fuel Oil Feeding Apparatus
IPC: F23K5/04
Filed: 1968-05-17
Abstract: A pump-and-valve unit, or arrangement, Figs. 1 and 2, for feeding a nozzle 2 with fuel-oil that is stored in a tank 4 comprises a rotary positive displacement pump 10 of the internally-meshing n and n + 1 tooth type furnished with a device 18 for removing air entrained with the oil and a combined pressure-regulating and cut-off valve 13. The device 18 is constituted by a flowrestricting passage 43, Fig. 3, in a cover plate 27 adjacent working chambers 33 between pumping gear-wheels 24, 25, said passage being connected to a passage 12 on the high-pressure side of the pump through passages 39, 40, 41 and to the tank through passages 44, 19. The passage 39 is in register with the chambers 33 on the high-pressure side of the gears and the passage 43 allows air in the said chambers to escape while permitting only a small proportion of the oil to do the same. A passage 34 in register with the chambers 33 on the low-pressure side of the gears receives oil from the tank through passages 11, 36, 37 and a chamber 30 containing a filter 31. The valve 13 includes a port 7 controlled by a body 47 fixed to an axiallymovable spring-loaded body 50 having a passage 52 and a flange 53 co-operating with an immovable bush 51 between the passage 12 and a passage 15 comprising two portions 15a, 15b and a chamber 16 for a seal 23 about a driving shaft 22, the portion 15b containing a non-return valve 17 and communicating with the chambers 33 on the lowpressure side of the pump. The bodies 47, 50 are retracted from the port 7 in accordance with the pressure-differential between the passages 12, 15, the passage 52 serving as a by-pass for the oil when said differential becomes excessive.

Title: Process for producing and novel water-soluble synthetic resins
IPC: C09D5/44
Filed: 1969-04-30
Abstract: A synthetic resin which is water-soluble on neutralization and is based on a polymer, the backbone structure of which consists of carboncarbon bonds which contains carboxy groups and has no hydrolysable linkages in its structure is prepared by reacting at least 30 parts by weight of a diene polymer having a weight average molecular weight of 200 to 20,000 with up to 70 parts of an unsaturated carboxylic acid having at least 6 carbon atoms to form a resin having an acid number of at least 40 mg. KOM/g. The diene polymer may be further reacted with a monomer such as a vinyl aromatic or (meth)acrylic monomer during the reaction with the carboxylic acid or subsequently. The resin is neutralized with e.g. ammonia, an amine, an alkali metal or alkaline earth metal hydroxide or a salt, or modified by reaction with a condensate of formaldehyde with a phenol, phenol carboxylic acid, urea or aminotriazine, or vulcanized using sulphur. In the examples, liquid polybutadiene is (a) reacted with dehydrated castor oil fatty acids, or a mixture of 9,12-linoleic acid and oleic acid, and treated with triethylamine, (b) reacted with a dimeric fatty acid and treated with KOH, (c) reacted with dehydrated castor oil fatty acids, followed by heating with styrene, the resulting resin being (i) treated with triethylamine and incorporated in a paint containing ethylene glycol monoethyl ether, red iron oxide and water or (ii) mixed with hexamethoxymethyl melamine and incorporated in a paint, or (d) reacted with dehydrated castor oil fatty acid, followed by reaction with a p-tert.-butyl phenol/formaldehyde resin and treatment with ammonia. Paints containing the resins as binder are applied to substrates by electrodeposition (see Division C7).

Patent ES-457427-A1 (ES)
Title: Microprocessor controlled signal pattern detector
IPC: G11B27/10
Filed: 1977-04-01
Abstract: Signals generated by double frequency magnetic recording are received by logic which is controlled, and sensed, by a sequence of program instructions from a microprocessor. In particular, a special pattern of signals is to be recognized. The special pattern of signals is known in the magnetic disc recording art as an address mark which is a unique pattern of interspersed clock signals and data signals. The pattern is made more unique from any other pattern of data by the fact that certain of the clock signals are missing. The ability to utilize a microprocessor, which is relatively slow, in a magnetic recording system in which the bit rate is relatively fast, is enhanced by a particular processor program instruction which is effective to access a next following instruction from program storage and then stop the clock of the processor. The clock is re-started, and therefore execution of the next instruction initiated, upon receipt of a timing signal from the logic receiving the signals to be detected.
