This product may be treated with an oxidising agent, such as manganese dioxide, to yield the 17b -acyloxy-des-A-estr-9-ene-5,11-dione having the above general formula where R is =O. Detailed examples are given in which the benzyloxy derivatives are formed and the ketal is the ethylene ketal. Other acyloxy substituents mentioned are acetoxy, trimethylacetoxy, propionyloxy, b - cyclopentylpropionyloxy phenylpropionyloxy, 4,4 - dimethylpentanoyloxy, 10-undecanonyloxy and hexahydrobenzoyloxy.

Patent ES-338924-A1 (ES)
Title: Method and apparatus for guiding a torch in lap welding
IPC: B23K9/02
Filed: 1967-04-05
Abstract: In welding apparatus for seam welding a lap joint between sheets, the welding torch is guided by means engaging the surface of one sheet to maintain the torch at a constant distance from such surface and by means engaging the edge of that sheet to align the torch with the edge. Metal sheets are lapwelded by first tack-welding and then continuously seam-welding without the use of filler metal. Sheets of thickness 0À012-0À158 in. may be so welded using a torch of the plasma arc or inert gas shielded non-consumable electrode type. The continuous welding of the tack-welded sheets 26, 27, Fig. 2, is effected by a torch mounted on a carriage 3 slidable on rods 8, 9 of a frame having four feet 21, 22, the front pair of which abut against the edge 43 of the upper sheet 26. A pinion 25 driven by a motor 4 on the carriage 3 engages a rack 16 on the frame to traverse the welding torch. At the end of the weld the rack 16 is rotated out of engagement with the pinion 25 and the carriage 3 is returned manually. The torch is carried in a holder 48 adjustably mounted on a bracket 5 pivotable about a shaft 28 mounted in the carriage 3 so as to be axially slidable and non-rotatable. A spring 38 presses the bracket 5 against a shoulder on the shaft 28. Rollers 56 or a slider carried by the lower end of the shaft engage the surface of the upper sheet 26 and so maintain the torch at a constant vertical distance from the sheet 26. The bracket 5 supports rigidly a rod 41 carrying a spring- loaded feeler 42 engaging the edge 43 and pivoting the bracket against the action of a spring 46b so that the torch follows a path corresponding to irregularities in the edge 43.

Patent ES-354399-A1 (ES)
Title: Thread guard with thread brake
IPC: B65H63/036
Filed: 1968-05-28
Abstract: A device for stopping a rotating thread supply bobbin acts directly on the surface of the yarn wound on the bobbin and is controlled by a device which detects yarn breakages. As shown the thread leaving a package 16 of a creel is sensed by breakage at 54. On breakage motion is transmitted through a linkage to pivot an arm 24 and bring a brake shoe 26 with tips 28 into braking contact with the package. A weight 58 may be fixed to shoe 26 and the motion transmitted through a spring 42 so that there is a delay in the operation to allow other parts of the machine e.g. the twisting spindle to be stopped. An electromagnetic delaying device may be used. The brakes of packages supplying yarn to a common station may be actuated simultaneously from a single thread breakage detector.

Title: Method for making a battery plate using cellulosic material
IPC: B01D39/20
Filed: 1968-08-16
Abstract: A process for the production of a metal replica of a fibrous material comprises so impregnating a natural cellulosic fibrous material with a solution of one or more thermally decomposable metal salts that the solution enters the fibres, drying the impregnated material, and by a single heating in a reducing atmosphere destroying the cellulosic material, decomposing the salt or salts to metal and sintering the resultant metal to produce a coherent metal body having a porosity corresponding to the pores within the fibres as well as to the gaps between them in the starting material. The cellulosic fibrous material may be cotton in sheet form, e.g. woven or knitted cotton or cotton wool, cotton or sisal thread, jute sacking, blotting paper or paper pulp. The metal may be Fe, Co, Ni, Cu, or alloys thereof, or W, Mo, Ag, Au or a platinum group metal, but Ni is preferred and NiCl 2 is the preferred impregnating salt. The heating step is carried out at a temperature of at least 900 C. in which case the heating time does not exceed 60 minutes, but heating at more than 1000 C. for not more than 30 minutes is preferred, the heating in each case being carried out in a reducing atmosphere such as cracked ammonia. A metal plaque may be formed from porous sheets made by the above process, by bonding said sheets by compacting and/or sintering and the plaque may be impregnated to form an alkaline battery plate, e. g. a bonded stack of Ni plates may be impregnated with NI(OH) 2 by conventional methods.

Title: Manufacture of crimped yarns
IPC: D02G1/12
Filed: 1968-12-12
Abstract: A method of producing a crimped synthetic yarn by heating the yarn asymmetrically to produce a latent crimp, is characterised in that a second crimp is introduced by subjecting the yarn to a direct crimping treatment, e.g. gearcrimping, stuffer-box crimping or air-crimping. In a preferred embodiment the yarn is heated to a temperature in the range 70-180 C by heater 5 prior to being crimped for example by gear-crimping rollers 6, 7. The yarn is preferably also drawn, the asymmetrical heating being carried out by a heated pin 10 contacting one of wraps of yarn around rolls 8 and 9. The surface temperature of the heated pin 10 is preferably higher than the softening point of the treated yarn, which yarn is preferably a polyamide or polyester yarn.

Patent ES-384759-A1 (ES)
Title: Pressure indicator, especially for measuring pressure in diesel engines
IPC: G01L9/16
Filed: 1970-10-21
Abstract: A sealing cone adapted to be secured on an indicating tap of a diesel engine has a central passage communicating with a diaphragm mounted in a housing. Another housing includes a force-measuring device such as a transducer. Pressure forces are transmitted from the diaphragm to the transducer by a central cylinder, and counter-acting tensile forces by a ring surrounding the cylinder and connected by sets of low-heat-conducting screws to both housings, the screws of the two sets being symmetrically spaced from each other around the ring. The cylinder and ring are formed of rigid thermally insulating material. The transducer is thus protected from the heat of the diesel engine.

Title: Devices for controlling the braking of vehicle wheels
IPC: B60T8/36
Filed: 1973-02-03
Abstract: A device for controlling the braking of at least one wheel of a vehicle travelling along the ground comprises apparatus for comparing the speed of the said one wheel with the speed of the fastest wheel of the vehicle. When the ratio of these speeds falls below a predetermined value the pressure in the braking circuit is reduced whereby to reduce the braking effect. The predetermined value is reduced as the speed of the vehicle is reduced to prevent reduction in the braking effect, for example when the vehicle is travelling around a relatively tight curve at a relatively low speed without any wheel slip.

Patent ES-8103478-A1 (ES)
Title: Lead frame and housing for integrated circuit.
IPC: H01L23/04
Filed: 1980-02-20
Abstract: A lead frame and chip carrier housing are disclosed which can be used in packaging integrated circuit chips of a range of sizes and requiring varying numbers of leads in the lead frame. The lead frame comprises a centrally located square support portion having simple leads extending from its side edges and having composite leads extending from its corners. Each of the composite leads comprises a trunk lead and branch leads which extend from the side edges of the trunk lead. A relatively small integrated circuit chip can be used with the lead frame by removing only the support portion, locating the chip adjacent to the opening and connecting the simple leads only to the terminal areas of the chip. The lead frame can be used with larger chips having greater numbers of terminal pads by removing the support portion, removing inner end portions of the simple leads, and removing inner end portions of the composite leads so that some or all of the branch leads become available for establishing electrical connections to the chip. The chip carrier housing comprises an open frame member of insulating material molded onto intermediate portions of all of the leads. The inner ends of the leads are imbedded in a thin web which extends from the molded frame inwardly towards the center of the lead frame. Portions of this web are removed when the central opening is formed in the lead frame for the chip.
