Patent ES-358284-A1 (ES)
Title: Machine tool with tool changer
IPC: B23Q3/157
Filed: 1968-09-18
Abstract: A tool magazine 17 is swung in a vertical plane from a storage position to a position beneath a tool spindle 13 of a drilling machine by means of two arms 22, 24 and a driven pinion gear 26 meshing with a gear 25 fixed to the arm 24. The magazine is locked in its storage position by a pneumatically operated lock 29. The magazine comprises an indexable plate 35 having tool holding recesses in its periphery and being rotated by a motor 45 via pulleys and a belt. The tools are held in holders 71 having a pair of spaced rings 73, 74 that engage in the recesses of the plate 35. A detent spring (81), (Fig. 4, not shown) locks the tool holders into the recesses. The detent spring is moved to unlock the tool holders by the end of a quill 12 during a tool change operation. The tool holders include driving dogs that engage in slots in the end of the spindle. Should they not engage properly the plate 35 is forced downwards by the spindle 13 against a spring to operate a switch that raises the spindle for a further attempt at engagement. Chucks.-The end of the quill 12 has attached thereto a housing (93) (Fig. 6, not shown) in which is mounted a pneumatically operated clamp ring (96) and friction band (97). When a tool holder is inserted into a tapered bore in the spindle 13, the driving dogs engage with slots (110) in the spindle, which has been previously aligned to a tool receiving rotational position. The tool holder is clamped by rotation of the spindle through 90 degrees until pegs (113) abut stops (114). During this rotation the clamp ring (96) and friction band (97) are forced by fluid pressure against a nut member (94) screwed on to the end of the spindle to cause relative rotation therebetween, which relative rotation causes the nut member to force the tool holder into the spindle. Indexing.-The plate 35 is indexed by the motor 45 and a belt and pulley drive. A disc (51) having peripheral holes corresponding to the tool recesses in the plate 35 is also rotated by the belt and pulley drive and operates limit switches at pre-selected positions. A pneumatically operated plunger 58 then locks the position of the disc (51) and plate 35. The machine tool is tape controlled to automatic programme sequences and is controlled electro-hydraulically. The drilling machine comprises a vertically movable spindle head 11 and includes separate drive motors 14, 15, 16 for the spindle 13, the spindle head 11, and the quill 12, respectively.

Patent ES-373353-A1 (ES)
Title: Improvements to data processing systems duplicated for reliability purposes
IPC: H04Q3/545
Filed: 1969-11-08
Abstract: A data processing system, for example, for controlling a telephone or telegraph exchange, comprises two identical digital computers which normally both operate simultaneously so as to be capable of operating the exchange, but only one of which actually controls the exchange so that if the controlling computer fails in any way the other computer takes over immediately. One computer ENS1 is shown in Fig. 1 with the other computer ENS2 (not shown) being leftwards thereof. The computer comprises a line block BL, a computing block BC, a ferrite core memory MF and a magnetic drum memory MT. In operation the block BL scans incoming lines REC, detects telegraph signals, processes them, and stores characters in the memory MF. The computer block BC takes the characters and forms them into messages which it stores in the memory MT together with operating instructions. When the message is to be retransmitted the block BC transfers it to memory MF from whence it is transmitted via block BL only if the gate pt is enabled by a signal SLIG. If the signal SLIG is not present no transmission is made from computer ENS but one is made from computer ENS2, and vice versa. An exchange memory ME ensures that both computers process at the same speed. Error detection in a computer.-A testing circuit CC receives periodic signals FAM from block BL and signals S11 from the block BC which indicate the respective units are still functioning. A signal FPR is sent when the computer programme is in error. If there are no errors, circuit CC sends a signal #FOT to a change over NAND gate PB which indicates whether computer ENS1 is on line or not. When ENS1 is on line, ENS2 is off line and produces a signal SLIG equivalent to #ADC, and the condition register RE provides signal LIG. Hence the NAND gate PB suppresses the signal #SLIG, and the computer ENS1 is on line as inverter IN provides signal SLIG to enable gate pt. If an error occurs, circuit CC sends signal FOT, the gate PB sends signal SLIG which is signal #ADC to computer ENS2, at the same time disabling gate pt. Hence the two computers ENS1 and ENS2 are immediately interchanged. The signal FOT goes to the block BC and causes a restart programme to commence (Fig. 2, not shown) which restores all the circuits of blocks BL and BC to zero, increases a failure counter by one and stops the computer if the counter has reached a certain level (the counter being periodically restored to zero). Otherwise it reloads the operating programme from drum TA and the computer is then ready to go on line again.

Patent ES-415931-A1 (ES)
Title: Apparatus for diverting a pipeline
IPC: F16L1/19
Filed: 1973-06-14
Abstract: An apparatus for diverting by application of plastic stresses, a moving pipeline between the top and bottom surfaces of a marine body of water. The pipeline is made of an elastoplastic metal pipe having a suitable coating of corrosion-proofing material. The pipe is initially bent at the top water surface to a constant radius of curvature over a finite arcuate length, and subsequently straightened to a substantially rectilinear configuration colinear with the pipe's trajectory. The radius of curvature is sufficient to prevent buckling of the pipeline and the applied moment yields the pipe material in a controlled fashion to obtain a relatively large change of direction in a relatively short finite arcuate length. The application of the moment is such that the coating remains substantially intact and flattening of the pipe's cross section remains negligible. Under such conditions, the constant radius of curvature of the diverted pipe and the finite arcuate length may be selected to allow the diverted pipeline to assume any desired inclination angle without the need of customary expensive and large vertical support structures. Suitably applied tension stress depending on this angle prevents the pipe from buckling at the marine bottom.
