Patent ES-363900-A1 (ES)
Title: Gas treatment apparatus
IPC: F26B3/092
Filed: 1969-02-11
Abstract: An apparatus, Fig. 1, for treating a fragmented material M by a gas, comprises a chamber 1 with a horizontally disposed perforated floor 2 supporting the material, a gas forced through the floor from underneath to fluidize and treat the material, a motor 6 to vibrate the floor 2, and walls bounding each perforation 3 which extend downwardly and whose length L is equal to or greater than the amplitude of vibration 2A of the floor and which are in contact with the gas on all sides. In a drying, heating or cooling apparatus the gas is maintained at a high pressure by a pump 4 and is fed below the floor 2 via a heater or cooling apparatus 5. The floor 2 may consist of a plurality of U-shaped parallel bars 11, Fig. 7, spaced apart to provide the perforations 3. The walls bounding the perforations are formed by the downwardly extending wings of the U-shaped bars 11, one wing of which may be slightly extended downwards and provided with a perpendicular extension 16 which underlies the unextended wing of the adjacent bar 11 in order to prevent excessive loss of the material M when the apparatus is inoperative. The perpendicular extension which may be shaped to increase the gas flow velocity may be on either wing but always on the same wing of each bar. The wings on each bar may alternatively be of the same length and the free ends may be slightly inclined towards each other (Fig. 4, not shown). The parallel bars 11 are held in two horizontal slideways (13, Fig. 5, not shown), each bar being provided with spacers (14). Where the bars 11 fit into the slideways (13) they are closed by a further U-shaped member (13). The bars are preferably disposed perpendicularly to the direction of flow D of the material M through the apparatus. Alternatively Fig. 8 (not shown) the floor (2) may be formed from a thin sheet having staggered rows of orifices (3) which have inserted therethrough tubes (18) which are further supported by members (21) connecting rows of tubes together.

Title: Method and apparatus for resistance welding
IPC: B23K11/24
Filed: 1969-02-24
Abstract: In electrical resistance welding an alternating current is supplied to the electrodes in contact with the work, of such a frequency that the reactance of the welding current circuit including the electrodes and the work is higher than the resistance of the circuit. An apparatus for making metal blanks 11 into tubular cam bodies comprises a horn 12 and advance means 13 for moving the blanks 11 along the horn and an apparatus 14 for forming the blanks into tubular shape encircling the horn with overlapping edges. Roller electrodes 18, 24 are provided to contact between them the edges to be welded, although sliding or shoe electrodes may be used. The roller is mounted on a fluid piston/cylinder device 30, 31 so that the roller 24 is pressed tightly to sandwich the edges to be welded. Alternating current is supplied from a generator 35 including a step down transformer to the electrodes 18, 24 and a tack welder including electrodes 37, 38 may be provided to tack weld the overlapping edges prior to insertion between the electrodes 18, 24. The circuit from the generator to the edges to be welded includes the resistances of the rollers, of the connectionof the rollers to their leads (the constant resiss tances R) the resistances at the contacts of the rollers with the edges, of the edges and of the interface between the edges (the varying resistances RV) and includes the inherent self inductance of the circuit and the inductance or capacitance of an inductor or capacitor included in the circuit. In Fig. 5, the ohmic resistance of the circuit is presented by Rt=Rv+R and the ohmic reactance is represented by XL. The frequency of the generator 35 supplying sinusoidal or square wave current is selected so that the ohmic reactance XL is higher than the ohmic resistance Rv so that the varying resistance Rv has little effect on the current passing between the electrodes being determined by the impedance Z=#Rt2+XL2. It is stated that the edges may be butted instead of lapped and may be of separate sheets, also that the welding may be spot or butt welding.

Title: Perfluoropolyethers modified with quinone compounds in the polymeric chain and process for their preparation
IPC: C08G65/00
Filed: 1971-03-02
Abstract: Modified perfluoropolyethers containing, within the polymeric chain, repeating units derived from a quinone compound, are obtained by reacting a peroxidic oxygen-containing perfluoropolyether with a quinone compound, either at an elevated temperature between about 100 DEG and 350 DEG C or under radiation with ultraviolet light at least a portion of which is in the 200-300 millimicron range, whereby the peroxidic bridges are gradually replaced by the quinone units. The reaction is believed to proceed by a free-radical mechanism. The resulting products may be linear, branched, or cross-linked, depending upon the reaction conditions, ratio of reactants, and nature of the starting materials. The products are essentially unvulcanized rubbers which can be vulcanized by common vulcanizing agents such as diamines.

Patent ES-416025-A1 (ES)
Title: Speed control system for a-c supplied universal motors
IPC: H02P25/10
Filed: 1973-06-18
Abstract: A double polar thyristor, such as a Triac is connected in series with the universal motor. The Triac is triggered by two independently operating trigger circuits. One trigger circuit operates at a phase angle phi 1, between 70 DEG to 110 DEG , preferably about 90 DEG . The second trigger circuit permits passage of current through a much larger phase angle phi 2, for example 180 DEG . Load on the motor is sensed by sensing commutating pulses, and when the commutating pulses exceed predetermined values, the second trigger circuit is enabled. The motor, thus, under no-load conditions, will be triggered only by the first trigger circuit, the second trigger circuit becoming effective, for selected statistically distributed half wave pulses as the load on the motor increases, the statistical distribution, in time, of the trigger pulses from the second circuit (providing, preferably, full wave application of power to the motor) occurring in accordance with loading on the motor.

Patent ES-441625-A1 (ES)
Title: Purification device
IPC: B01D21/24
Filed: 1975-10-09
Abstract: Devices to remove polluting components from waste liquids are usually designed to operate satisfactorily as long as the input flow rate remains less than some maximum allowed value. Greater flow rates will cause inadequate purification and resulting downstream pollution, as well as possible damage to the device. An emergency overflow weir may be provided to divert excessive input flow into a buffer vessel or alternative discharge channel. The weir will divert a part of the excess flow, but the remainder will pass through the device the relative portions depend on the relative flow resistance of the weir and of the device, respectively. The present invention enhances the flow resistance of the device when the flow rate through it is greater than the maximum allowed value, so that a greater fraction of the excess flow will be diverted by the emergency overflow weir.

Title: Lead connector for a body implantable stimulator.
IPC: A61N1/375
Filed: 1979-04-02
Abstract: In a connector for interconnecting a furcated lead (10) and signal generator (16) to form a body implantable stimulator, the connector (17) is secured to the signal generator to form a signal generator assembly. Jacks (26, 30) are provided in the connector to receive the lead furculae while facilitating conformance of furculae to the configuration of the signal generator on wrapping of the furculae around the signal generator (16). The jacks (26, 30) accept the furculae at different distances from the signal generator to allow a thinner signal generator assembly and at different depths to compensate for the difference in distance of the jacks (26, 30) from the signal generator (16). In this way the hitherto encountered problem of fibrosis caused by the excess length of furculae is greatly reduced.

Next, an octyl alcohol is added in a stoichiometric amount based on unreacted acid groups along with 10 to 50 percent of the stoichiometric amount of octyl alcohol as excess. An esterification catalyst is added and the reaction mixture heated for a time and at a temperature sufficient to carry the esterification to substantial completion.
