Title: Pattern installation for circular knitting machines
IPC: D04B15/74
Filed: 1968-08-09
Abstract: Two selections are made at each feeding station of a circular machine by providing a double vertical bank of presser members 141, 14II which are actuated by one and the same pattern drum, the first bank of presser members when actuated deflecting the corresponding jacks inwardly so that they and their needles remain at a low level A whilst those jacks not engaged by pressers 14I are elevated by a raising cam 9 to a tuck height B. At this level the second bank of pressers 14II makes a selection and the pressers 14II actuated by the pattern drum deflect the corresponding jacks inwardly so that they and their corresponding needles remain at tuck height 'whilst the remaining jacks and their needles are elevated to a yarn clearing and knitting height. Consequently a double selection is made at each feeding station one at miss height and one at tuck height by the actuation of a double bank of pressers from a single pattern drum. For this purpose the pattern drum is advanced twice the distance between the vertical rows of the pegs in the drum so as to correspond to the distance between the banks of pressers.

Patent ES-363412-A1 (ES)
Title: Method for producing semiconductor integrated circuit device and product produced thereby
IPC: H01L21/74
Filed: 1969-01-31
Abstract: During semi-conductor device manufacture at least one N(P) type zone 42, 43 is diffused into the surface of a P(N) type substrate 41 and a P(N) type epitaxial layer is deposited thereon. N-type contact zones 46, 48 are then diffused through the epitaxial layer to meet the now buried N-type zones 42, 43 around their entire peripheries, and a P-type dopant is diffused non-selectively into the entire surface of the epitaxial layer, the P-type doping level being selected so as not to convert the surface of the N-type contact zones 46, 48 to P-type conductivity. Further selective N-type diffusion into the zones 46, 48 may be employed to offset the compensation produced therein by the non- selective P-type diffusion. In the P-type islands surrounded by the buried zones 42, 43 and the contact zones 46, 48 devices such as bipolar or field effect transistors, diodes, resistors or capacitors may be formed, using selective diffusion where necessary. With silicon as the semi-conductor material suitable dopants mentioned are boron, arsenic, antimony or phosphorus.

Patent ES-399349-A1 (ES)
Title: Quill or bobbin spinning and winding frame with semi-automatic doffing and donning
IPC: D01H9/14
Filed: 1972-01-31
Abstract: A spinning frame or a ring twister frame with semi-automatic doffing and donning is provided with a doffing bar on the usual ring rail with projections which in one position of the doffing bar are opposite each wound bobbin. The ring rail is pneumatically lowered when the bobbins are fully wound to a position just below the normal starting position and the doffing bar moved so that the projections are underneath the bottom ends of the bobbins. The pneumatic cylinder used to bear down the rail is double acting, and when the doffing cycle is manually started raises the ring rail to a position high enough to lift the wound bobbins off their spindles. At the same time, a wall is tilted, forming a chute into which the bobbins fall, and a conveyor in the bottom of the chute carried them to a full bobbin container. In the case of spinning frames, there is carried on the ring rail a donning tube with holes opposite each spindle, and before initiating the doffing cycle the operator fills these holes with empty cores or bobbins upside down. The next actuation pneumatically brings the donning tube over the rings in the ring rail and causes the tube to rotate 180 DEG . The empty bobbins fall down onto the spindles and then the ring rail is borne down again to normal position for starting winding. This produces a slack on the traversing chain and a pneumatic cylinder rewinds this to starting position. When the starting button is pushed, winding starts as usual.

Patent ES-438259-A1 (ES)
Title: Telecommunication system controlled by stored program instructions
IPC: H04Q3/54
Filed: 1975-06-05
Abstract: A SPC-telecommunication system comprises test points, operating points, data-bus interconnected data storage registers, a phase generator and an access signal generator. The registers include instruction registers for storage of instructions, and an unit-incrementing address register for storage of addresses identifying the instructions. The phase generator produces phase signals by which the processing cycles of the instructions are divided in phases. The access signal generator is controlled by the phase signals, the addresses and the instructions. For producing access signals in order to control the test points, operating points and registers, the access signal generator includes logic arrangements or units. A first logic unit decodes the contents of the address register during the beginning phase of the respective cycle and accesses the instruction register associated with the respective address during the other phases of the cycle. A second logic unit initiates a unit incrementing of the address register during a middle phase of each cycle. A third logic unit allows transfer of an address from one of the registers to the address register only during the end phase of the respective cycle. A fourth logic unit carrying out an AND-function has its inputs activated during the end phase of a cycle for accessing one of the test points and its output connecting to the unit-incrementing input of the address register.
