Patent ES-406048-A1 (ES)
Title: Method for controlling forces on a strand as it solidifies
IPC: B22D11/20
Filed: 1972-08-23
Abstract: A method and mechanism for controlling the forces on a partially solidified strand formed in a continuous-casting operation. A speed-regulating tractive force is applied to the strand at a location in the line preceding that where the starter bar is disconnected. In apparatus utilizing a relatively long flexible starter bar, auxiliary tractive forces are applied at preceding locations. In apparatus utilizing a rigid starter bar or a relatively short flexible bar, the auxiliary tractive forces may be applied at locations following the speed-regulating force. The speed-regulating force is maintained at a predetermined maximum, and the auxiliary forces adjusted accordingly to supply the increasing force needed to move the strand, yet avoid excessive tensile or compressive stresses.

Title: Self adjusting tangency-clearance compressor with liquid purge capability
IPC: F04C29/12
Filed: 1974-12-04
Abstract: A vane-type compressor especially adapted for compressing refrigerant in air-conditioning systems has a vane carrying rotor mounted on fixed center bearings and surrounded by an eccentrically positioned cylinder guiding the vane motion and confining and controlling the compression process which is free to swing toward the rotor and maintain a line of tangency contact therewith providing a direct barrier between the discharge and suction sides of the compression chamber. A spring loaded end plate pressed against one end of the cylinder serves as a relief valve to purge liquid such as lubricant which might collect in the compression cavities during a shut-down period and which could otherwise create a lock-up condition. A fixed front bearing plate or end head has a cup-shaped housing piloted thereon surrounding the cylinder and providing a rear bearing mounting for the rotor. The front plate has an inlet port supplying the compression cavities between the rotor and cylinder. The cylinder has an outlet adjacent the tangency seal line of contact between the rotor and cylinder which discharges to a chamber between the housing and cylinder that is surrounded by porous fibrous strips effective to separate lubricant entrained in the compressed refrigerant. The refrigerant is discharged to an outlet port in the front bearing plate and the separated lubricant collects in the bottom of the housing and is circulated back to the bearings and vane slots of the rotor.

Title: Flux control system for controlled induction motors
IPC: H02P21/00
Filed: 1975-03-05
Abstract: An induction motor, supplied by a static converter power supply which is independently adjustable as to frequency and voltage, is voltage controlled so as to keep the flux at an optimum constant level while the frequency is varied and load conditions change substantially. Flux regulation is obtained from a signal processor providing a synthesized representation of the square of the magnetizing current multiplied by the frequency derived from the analog sensing of the supplied voltages and currents. In a negative feedback loop the synthesized signal is compared to a reference signal which is proportional to frequency, and the voltage is controlled therefrom, whereby the magnetizing current developed on the stator of the motor remains constant when frequency varies.

Title: Device for the pre-folding of the closure of a folding box
IPC: B31B50/32
Filed: 1976-05-03
Abstract: The invention relates to a process and apparatus for pre-folding and unfolding of a closure on a folding box of rectangular cross-section, which closure is formed of the creased unslotted end portion of the walls of the box of which two opposite closure panels are each provided with a pair of creases running from the corners and converging toward the center of the margin so as to form triangular pockets upon folding. The device comprises two pairs of folding tools at 90 DEG to one another and means for displacing them. One of the pairs corresponding to the creased panels each is bifurcated with a folding tine which engages its panel at substantially one location during folding while the other tine in inactive and an unfolding tine which engages the opposite face of the same panel during unfolding while the folding tine is inactive. A plunger is moved into the box prior to folding to serve as a backing means and, by unfolding as described, the panels are restored to a position where they are at most only minimally contacted by the plunger during withdrawal from the box. Thus, if the end portion of the box carries an adhesive material for later closure, the adhesive will not be removed by sliding of the plunger therealong.

Patent ES-8100222-A1 (ES)
Title: Process for Manufacture of Phosphoric Acid and Phosphorus Pentafluoride
IPC: C01B25/10
Filed: 1980-01-03
Abstract: A method for the manufacture of phosphoric acid comprises treating calcium phosphate sources such as bone phosphate and phosphate rock with fluorosulfonic acid in the presence of a limited amount of water as catalyst whereby over 98.00% of the phosphorus is converted to volatile compounds that can be subsequently hydrolyzed. A substantial excess of fluorosulfonic acid is utilized to contact the phosphate ore as a slurry. The phosphorus products are primarily phosphorus pentafluoride and phosphorus oxyfluoride. The production of phosphorus pentafluoride is favored by up to one part of water to eight parts of ore by weight in the presence of excesses of fluorosulfonic acid. Hydrolysis of the volatile compounds gives phosphoric acid and hydrogen fluoride. Hydrogen fluoride is then recycled to react with the required sulfur trioxide to make the requirement of fluorosulfonic acid for the process.
