Title: Apparatus and method for use in fluidized powder filling of multiple core unit cables.
IPC: H01B13/22
Filed: 1979-07-27
Abstract: For powder filling of cables, in a fluidized powder bed, has been proposed to pass the cable core through a bed in a substantially closed condition. There is a limit to the number of conductors a core can have for effective filling. In the present invention the cable core is opened up into a number of core units by passing through an opening member (50). The opening member is freely ridable on the cable core and has a hole (55, 55A) for each unit. The opener is held against a support member (40) and an air bearing formed between the two members. Air is also usually fed to the holes (55, 55A) in the opener member through which the core units pass to prevent flow of powder out from the bed. The opening member can be positioned in the fluidized bed or outside immediately prior to passage of the cable core through the bed. The units are each in a substantially closed condition in the bed and the units close to a single core also in the bed.
Patent ES-483046-A1 (ES)
Title: Device for electronically controlling the intake air temperature of an internal combustion engine
IPC: F02M31/06
Filed: 1979-08-01
Abstract: A device for electronically controlling the intake air temperature of an internal combustion engine, featuring a temperature sensor in the clean air space of the filter, the signal from the sensor controlling an electromagnetically driven oscillator pump whose vacuum output adjusts the flapper of an air flow proportioning valve by means of a pneumatic actuator, until the correct ratio of cold and preheated raw air is admitted into the intake system for the establishment of an optimal combustion air temperature. An automatic lowering of this temperature under full-load operation is achieved by utilizing the negative pressure in the air intake manifold as a control means to shift the oscillating armature of the oscillator pump away from its maximum output position. In an air intake system for fuel-injected engines, a similar result is achieved by means of an air flow sensor whose output signal is superimposed on the control signal from the temperature sensor.

Patent ES-8306897-A1 (ES)
Title: Self adjusting, distributed control, access method for a multiplexed single signal data bus.
IPC: G06F13/368
Filed: 1982-10-01
Abstract: A method of providing access to a multiplexed data bus having a plurality of data processing units coupled thereto. Each unit self-assigns sequence numbers thereto for identification purposes. The unit having the lowest sequence number obtains immediate access to the bus and may relinquish the bus by transmitting a control word, or token, with an incremented sequence number. All units receive the token but only the unit having the incremented sequence number gains access to the bus. The token passing continues through the series of sequence numbers and then recycles when no unit accepts the token (bus timeout). A newly added unit self-assigns a sequence number equal to the one transmitted prior to the bus timeout and thus acquires bus access on the next cycle. If a unit in the cycle fails, a bus timeout occurs mid-cycle and the access loop recycles. The units not gaining access to the bus during the cycle decrement their sequence numbers to close the gap, and hence gain access on the next cycle. The method allows for continuous system operation if units are added or deleted, without interrupting bus operation.

Patent ES-8502063-A1 (ES)
Title: Apparatus and method for locally heating conveyed glass sheets.
IPC: C03B29/08
Filed: 1983-08-19
Abstract: An improved apparatus including a localized heater that moves along the direction of conveyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment. This invention is especially suitable for locally heating designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the designated portion of glass sheets are to be formed with bends having relatively short radii of curvature at a bending station. The apparatus includes a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending. These heaters are mounted on a carriage driven by a drive mechanism. The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage. After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its upstream position in preparation for another cycle.

Patent ES-8502608-A1 (ES)
Title: Methods of bonding.
IPC: A43D25/20
Filed: 1984-04-05
Abstract: A method of bonding soles to shoes using a moisture curable adhesive composition is described. The method involves application of a layer of the adhesive, preferably as a melt at a temperature between 80 DEG C and 100 DEG C to a sole and/or a show upper, chain extension of the polyurethane by moisture, heat activation of at least one of the layers and pressing the sole and shoe upper together. The method exhibits tolerance of chain extension conditions and of delays prior to heat activation and also leads to bonds of good initial and final values. The adhesive comprises a polyurethane prepolymer having NCO groups available for reaction, and a monofunctional reactant present in amounts sufficient to react with up to 40 mole % of the isocyanate groups of the prepolymer. Preferred polyurethanes are based on polyesters from aliphatic dicarboxylic acids and diols together with aromatic diisocyantes for example MDI. The monofunctional reactant influences the extended ability of a chain extended layer of the adhesive to be activated by heat after comparatively long periods in combination with the achievement of good bond strengths.
