Title: Method and apparatus for selectively plating elongated bodies of metal
IPC: H01R43/16
Filed: 1970-04-14
Abstract: An electrical contact is made by forming spaced apart locating pilots in a metal tape 24, selectively coating the tape 24 which resist material so as to form regularly recurring non- coated areas 40, plating a non-corrosive metal on to the non-coated areas 40 of the tape 24, removing the resist material and punching and forming the tape to form individual contacts, each having a plated wear area adapted to engage a similar wear area on another contact. A cadmium bronze tape 24 is passed through a punching press (22), (Figs. 2 and 4, not shown), where pilot holes 25 are formed by a punch (26b). The tape 24 is currently positioned by a side guide (26c) and a locating pin (26a) engaging a previously formed hole. Alternatively, the tape 24 may be provided with printed or embossed areas adapted to be sensed in subsequent processing steps. After cleaning the tape at (30), it is selectively coated with printing ink by rollers (34), (Fig. 5, not shown), so as to form non-coated areas 40, the ink being dried at (36). The holes 25 in the tape 24 are engaged by projections (38) on the rollers (34) so as to precisely locate the bare areas 40. The tape is next passed beneath cleaning nozzles 41 and into a plating tank 47 containing an anode 48 and supplied with a potassium gold cynanide electrolyte from a reservoir 52 whereby the bare areas 40 are plated with gold having a thickness of 30 micro inches. If a relay 53 detects the absence of plating current, the electrolyte is drained into a container 53A to prevent the cadmium in the tape dissolving in the gold solution. The printing ink is subsequently removed by spray nozzles 44, downstream of which the plating power supply is connected to the cleaned tape 24. After plating, the area of each contact member is precisely located in a punch press 56 and the contacts formed and separated from the tape by dies 57. The contact is formed with a protuberance (20), (Fig. 1, not shown). The contacts are finally electrolessly plated with gold to a thickness of 2-5 micro inches.

Patent ES-447960-A1 (ES)
Title: Positioning system for data storage apparatus and record medium for use therewith
IPC: G11B5/55
Filed: 1976-05-14
Abstract: A positioning system for data storage apparatus in which a magnetic transducer is positioned relative to data tracks on a moving record member by means of a closed loop servo system. Improved velocity control information is provided to the servo system by pre-recorded servo tracks read by a single servo head forming part of the closed loop system. Each servo track consists of a plurality of servo cells, alternate ones of which are laterally displaced by half a track width. A position reference signal is prerecorded in each cell at a point which is predetermined to permit the signal to be sensed by the single servo head independently of any other detectable signal. Accordingly, a position error signal derived from displaced cells is always 90 DEG out of phase with the position error signal derived from undisplaced cells. During a track access operation, when the servo head is moved from one track to another track, the displaced and undisplaced cells are sensed by the single servo head to provide two separate position error signals. Control circuits combine selected portions of the two position error signals to provide a composite signal of improved linearity from which the velocity of the head during the access operation can be ascertained directly and employed to perform control functions dependent on velocity.

Patent ES-467823-A1 (ES)
Title: Apparatus for forming glass containers
IPC: C03B9/14
Filed: 1978-03-14
Abstract: Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the parison. The parison transfer mechanism carries the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the upright position at the blow mold or to help sustain the parison against collapse during invert. The ability to apply puffing air to the parison during transfer is a significant step in the forming process.

Patent ES-479240-A1 (ES)
Title: Desizing of textiles consisting of or containing cellulose
IPC: D06L1/14
Filed: 1979-04-03
Abstract: In addition to the very time-consuming enzymatic and hydrolytic desizing processes, oxidative degradation of starch size by means of persulfate, to render the starch water-soluble, is conventionally practised. Because of the chemical similarity between starch and cellulose, oxidative degradation of the cellulose is unavoidable in this desizing process. The invention overcomes this problem by breaking up the macromolecules of the starch into dispersible fragments by means of such small amounts of persulfate that neither is the starch made water-soluble nor is the cellulose significantly damaged, the dispersants employed for the fragments being relatively oxidation-stable polymers of unsaturated carboxylic acids.

Patent ES-8101748-A1 (ES)
Title: Method of drying pipelines and putting gas thereinto
IPC: F17D1/04
Filed: 1979-12-14
Abstract: The invention relates to total elimination of aqueous deposits in pipelines intended for transporting gaseous fluids, such as a natural gas. The method involves sending, by a nozzle at an end of at least one compressed air ejector, connected with the pipeline, a pressurized driving fluid (for example, under 4 to 8 bars) into a pipeline which aspirates and entrains the gaseous fluid (air+water vapor), the mixture of fluids then being discharged at the other end of the ejector. In practice, multistage ejectors for example three ejectors in series, are used. According to a variant of the method, the step of putting gas which is to be transported into the pipeline is done while the vacuum is maintained in the ejector or ejectors so as always to be outside the limits of flammability of this gas. The method is particularly suitable for drying natural gas pipelines and then putting the pipelines under pressure.
