Patent ES-388173-A1 (ES)
Title: Color signal producing system utilizing spatial color encoding and comb filtering
IPC: H04N9/07
Filed: 1971-02-11
Abstract: Colored light from a scene is spatially encoded onto a photosensitive surface by a striped spatial color encoding filter assembly including first and second superimposed encoding gratings having equal pitch encoding stripes disposed such that the stripes of the respective gratings are at substantially equal and opposite angles measured from a reference line in the plane of the filter. Scanning of the encoded image on the photosensitive surface produces a composite signal including first and second carrier wave components representative of first and second colors and having substantially the same frequency during a scanning interval. The carrier wave components are separated by comb filter apparatus for producing separate color representative signals.

Title: 4{40 -Epi-6{40 -hydroxyadriamycin and method of use
IPC: A61K31/70
Filed: 1975-10-28
Abstract: The novel glycoside antibiotic: 4'-epi-6'-hydroxydaunomycin is prepared by condensing daunomycin with a novel protected, reactive derivative, which is 1,2,3-trideoxy-4,6-di-O-(p-nitrobenzoyl)-3-trifluoroacetamido-L-arabin o-hex-1-enepyranose and thereafter removing the protecting groups. A further novel glycoside antibiotic: 4'-epi-6'-hydroxyadriamycin is prepared by reacting 4'-epi-6'-hydroxydaunomycin with bromine to form an intermediate bromo derivative which is then mildly hydrolyzed to form 4'-epi-6'-hydroxyadriamycin. These novel glycoside antibiotics, while not as effective as the parent compounds daunomycin and adriamycin in the treatment of tumors, are considerably less toxic than the parent compounds.

Patent ES-448154-A1 (ES)
Title: Vehicle speed control circuit
IPC: B60K31/04
Filed: 1976-05-21
Abstract: An apparatus for automatically maintaining the speed of a vehicle at a desired road speed as selected by the vehicle operator. When the operator actuates the control circuit, a desired road speed signal proportional to the vehicle road speed at that moment is generated and stored. The stored desired road speed signal is continuously compared with a signal representing the vehicle road speed to generate a duty cycle modulated control signal to a throttle control which adjusts the vehicle throttle to maintain the desired road speed. The generation of the desired road speed signal is synchronized with the vehicle road speed signal to provide an accurate and highly repeatable desired road speed signal. The control circuit also includes an anticipatory control which responds to the operator actuation of the control circuit to pre-position the throttle control as the desired road speed signal is being generated and stored. This reduces the overall response time of the speed control circuit.

Title: Noise reducing assemblies for disc brakes for vehicles
IPC: F16D55/224
Filed: 1976-07-31
Abstract: In a disc brake of the sliding yoke reaction type the noise due to "squeal" or "twitter" is substantially eliminated by resiliently biassing the yoke in grooves in a stationary member so that it engages an upper face of a groove on one side of the brake and a lower face of a groove on the other side. A dampening assembly may be provided between the yoke and a complementary face of one of the grooves. Alternatively the noise may be reduced by providing an abutment of stepped outline on the yoke which engages a friction pad assembly to apply it to the disc when the brake is applied.

Title: Fuel injection pump for internal combustion engine and production apparatus of it
IPC: F02M59/46
Filed: 1977-11-11

Title: Electrostatic spraying enamel powder onto hollow objects - esp. to obtain uniform coating on the lids of domestic cookers
IPC: B05B5/12
Filed: 1977-01-11
Abstract: A hollow object, consisting of a flat base with a rim, is suspended so the base is vertical, and is then sprayed with electrically-charged enamel powder. During spraying, a gas stream is directed onto the lowest inner part of the rim, and a second, local spraying operation is then used to coat the lowest part of the rim with powder. An auxiliary spraying operation may also be used to coat the inner surface of the highest part of the rim, but the latter is pref. coated during the main spraying operation. The pref. plant uses a conveyor for the vertical suspension of the objects, while they travel past nozzles spraying powder onto the base and the inner surface of the upper rim another nozzle blows a gas stream onto the lowest inner part of the rim. The lowest part of the rim is then coated by yet another nozzle. Used for the electrostatic spraying of enamel powder, e.g. onto the lids of kitchen stoves. The influence of gravity normally prevents a uniform powder coating the invention eliminates this problem.

Title: Tool for use primarily in conjunction with a rockbreaker unit
IPC: E02D13/00
Filed: 1978-05-26
Abstract: A tool intended for use in conjunction with carrier machinery, primarily a rockbreaker, comprising two axially aligned elongated members, one of which may be introduced into the carrier machinery with one end and into a recess in the other (second) member with its other end. A third member surrounds the second member and is suspended by the carrier machinery. When the carrier machinery is in operation it impacts the engaging end of the first member, thereby impacting the second member, which may operate as a plunger for producing holes in the ground. The second member is driven into the ground in consequence of a series of short impacts of the carrier machinery on the first member. The second member is provided with means for engagement by the third member to enable the second member to be pulled out of the ground when the hole has the required depth.

Patent ES-8101318-A1 (ES)
Title: Device to convert a reversing contact assembly.
IPC: H01H61/01
Filed: 1980-04-10
Abstract: A device for shifting a contact arrangement in a thermally operating protective relay having a make contact, a break contact, as well as a double-throw contact, provides for shifting the arrangement from self-locking to automatic resetting by shifting the make contact by means of a piston which can be locked. The self-locking condition provided can be cancelled by arranging the make contact for motion, in the closing direction, by the piston which is supported so as to be freely movable. The plunger has a resilient hook which can snap into undercuts in the housing of the relay which establish the end positions of the plunger. The undercuts are arranged in steps so that two different end positions for the plunger are obtained when the plunger is rotated approximately 90 DEG . One end position corresponds to the automatic resetting of the contact arrangement. The other end position makes it possible to move the plunger to cancel the self-locking condition. Using this structure, only one piston is needed, and the shift can be made with one hand.
