Title: Bulk material unloader
IPC: B65G65/00
Filed: 1974-07-02
Abstract: This specification discloses a bulk material unloader of the type suitable for unloading materials from deep holds of bulk material carriers. In one preferred form of the invention, the unloader comprises a plurality of elevated wheels of open channel cross section divided into a plurality of material retaining pockets, said wheels being linked together in chain fashion whereby the contents of one wheel is directly discharged from each pocket into the wheel with which the first mentioned wheel is linked.

In another form, the elevator wheels are arranged adjacent to each other with their planes of rotation substantially parallel and in overlapping relationship. Gravity transfer chutes extend between the adjacent wheels so that the material being elevated is discharged from one wheel to the other. Again, a digging bucket wheel feeds the lowermost wheel of the elevator.

Title: Strap positioning apparatus
IPC: B65B13/34
Filed: 1974-10-25
Abstract: An apparatus for positioning a loop of strapping about an object at a strapping station preparatory to tightening the loop to shrink the same upon the object. A shuttle mounted for orbital movement in a closed horizontal path about the object receives and conducts the free end region of a length of strapping issuing from a dispenser and, during its orbital movement, carries such free end around the object and thus draws strapping from the dispenser and wraps the same circumferentially about the object to produce the loop.

Patent ES-436476-A1 (ES)
Title: Yarn-twisting method and apparatus
IPC: D02G3/36
Filed: 1975-03-26
Abstract: Method and apparatus for manufacturing yarn. The yarn has a flexible core at least part of which is twisted in a given direction while surface fibers are carried by the core at least at the twisted part thereof and are helically wound onto the exterior surface of the core in a direction opposite from the direction of twist thereof where the surface fibers are located. The yarn core initially has the fibers projecting laterally therefrom, and then the yarn core is false twisted while the fibers are helically wound into engagement with the exterior surface of the core when the initial twist is introduced into the same during false twisting with the helical winding of the fibers being in a direction opposite to the direction of the twist introduced into the core by false twisting thereof. The false twisting of the core is brought about by a simple rotary member which surrounds the core and is rotated with respect thereto at a speed sufficiently great to provide substantial slippage between the rotary member and the core, this rotary member having an end surface which engages the fibers and winds them helically against the exterior surface of the core during longitudinal feeding of the latter through the rotary member, with this action on the fibers resulting in the false twisting of the core.

One end of the shaft is provided eccentrically with an axially extending pin journalled to rotate within the journal provided in the trunnion. Thereby, the pin is displaced transversely as the disc is rotated about its axis.
Patent ES-441905-A1 (ES)
Title: Method for gaseous reduction of metal ores
IPC: C21B13/04
Filed: 1975-10-17
Abstract: An improvement in a method for the batchwise gaseous reduction of iron ore to sponge iron in a multiple unit reactor system including a cooling reactor and a series of reduction reactors. Reduction is effected with a gas composed largely of carbon monoxide and hydrogen generated by reforming a mixture of steam and natural gas or other gaseous hydrocarbons at an elevated temperature. The reducing gas pressure drop through the system is decreased by using an out-of-line cooling reactor and cooling gas loop, thereby making it feasible to use three or more reduction reactors in series and thus enhance the efficiency of utilization of the reducing gas.Also the use of an out-of-line cooling reactor permits independent control of both the gas flow rate and gas composition in the cooling loop.

Title: Method of manufacturing double-wall plastic tubing in which the outer wall has transverse corrugations and the inner wall is smooth
IPC: B29C48/33
Filed: 1977-07-16
Abstract: In the manufacture of double-wall plastic tubing in which the outer wall has transverse corrugations and the inner wall is smooth, in the case of annular transverse corrugations the air pressure between the two walls cannot be balanced with the external air pressure, resulting in deformations of the inner tube. To permit an equilibrium of pressure before the inner wall hardens, openings are pierced in the outer wall or openings are produced between the two walls for communication between the inner chambers of the transverse corrugations. After the hardening of the inner tube, these openings are reclosed by fusion.
Patent ES-462394-A1 (ES)
Title: Method of discharging gaseous vinyl chloride monomer from a polymerization reactor
IPC: B01J19/00
Filed: 1977-09-15
Abstract: The unreacted gaseous vinyl chloride monomer still remaining in a polymerization reactor from which the polymerizate has been removed can be discharged by blowing steam into the reactor from its top so that the gaseous monomer is pushed downward and moved out from the bottom of the reactor, followed by a conventional treatment for condensation. This method of discharge serves to put the reactor open to the ambient atmosphere without the emission of the unreacted monomer and, as such, solve the problems of the workers' health and environmental pollution.
Patent ES-466291-A1 (ES)
Title: Segmented storage logging and controlling
IPC: G06F12/00
Filed: 1978-01-24
Abstract: A system and method are disclosed for controlling text storage in a text processing system using a segmented, serial bulk storage device. A plurality of storage segments of equal length are further subdivided into portions of equal length. A typical page of text occupies more than one portion of a segment. During system operation a log or directory is built and written, in updated form, onto a portion of the storage after any text data is written onto the storage. To minimize the time in accessing the predetermined portion on which the log is stored and to minimize wear of the electromechanical accessing components, portions of more than one segment are dedicated for storage of the log and the segment nearest that on which the text data is written is utilized for storage of the updated log. The beginning of the log includes an activity count indicitive of the number of text storage operations that has taken place. The most current log is found by seeking the highest activity count. In addition to providing information relative to segments and portions on which text is stored, the log includes other characteristics to distinquish utilized portions and unused-available portions from portions that are not to be used because of hard errors thereon. Since data is read from the storage and recorded onto the storage by portions, provisions are made for writing into the memory, a number of error codes equal to the number of bytes in a portion when read errors occur in reading from the storage and during relocation for recording a number of error codes equal to a portion when the text data cannot be successfully read from the storage. Thus, the appropriate storage size is maintained for rekeying the text.

One or more cards may be eliminated from the card cage to allow for discrete wire or cable connection directly from the IO circuit board to an appropriate section of the plug board system.
