Patent ES-359563-A1 (ES)
Title: Method of gas-phase etching semiconductor material
IPC: C30B31/06
Filed: 1968-10-25
Abstract: A semi-conductor material is etched with hydrogen chloride gas carried in helium, argon, neon, xenon, krypton, nitrogen or a mixture thereof. The semi-conductor may be silicon, germanium or gallium arsenide. As shown, semi-conductor material 10 having a thin film mask (e.g. of silicon dioxide which has been selectively removed with aqueous hydrofluoric acid) is carried on a member 12 of graphite, graphite coated with silicon carbide or molybdenum and heated above 550 C. by radiofrequency energy from inductor coils 14 disposed around quartz cylinder 16. Dry gaseous HCl from tank 22 and He from cylinder 24 are used as etchant and carrier gas respectively. Etching may be stopped by shutting valve 28. The cylinder may be subsequently purged with helium.
Patent ES-360234-A1 (ES)
Title: Caliper disc brake and mounting means therefor
IPC: F16D65/56
Filed: 1968-11-14
Abstract: A disc brake comprises a rotatable disc 64, a fixed support 10 having a pair of circumferentially spaced arms 20, 22 and 24, 26, and a floating caliper with spaced end portions 30, 32 held against the arms by resilient means 34, 36, 38, 40 allowing limited rocking motion, the caliper including a housing 28 containing an actuating piston and straddling the disc to embrace friction elements 42, 44 which can be actuated by rocking the housing by means of an arm 54 extending from the housing. The caliper includes sleeves 108, 110 slidably mounted on pins extending through projections 126, 128 of the housing. When the pads are applied by actuating the piston, the caliper slides in the sleeves 108, 110 and the springs 34 ... 40 prevent rattle and allow limited sleeve movement to prevent "knock back" of the piston. The pads can also be applied when arm 54 is actuated by a parking brake cable 62. In this case the springs allow rocking movement of the caliper including the sleeves and return them to the off position when the lever is released. One piston is pivotally mounted on the housing and the other can pivot so that they remain parallel with the disc which is hollow and air cooled. The piston includes adjusting means comprising an adapter 175 slidably mounted in a hole in the piston 46 with an extension 182 carrying a spring ring 184 which frictionally engages a sleeve 180 threaded on a nut 176. The sleeve 180 cannot state but can move axially through the distance 180. A torsional spring 196 is mounted between the adapter and the nut to rotate the nut and thereby maintain the adapter against the piston as it moves forward due to brake wear. The inside of sleeve 180 is connected to the surrounding space by passages 177, 179 to allow bleeding through screw fitting 194. (For Figures see next page.)

Title: Red wine-making process - with colouration tank for the must
IPC: C12G1/02
Filed: 1971-12-24
Abstract: Process is of note because at least a portion of the grapes is mixed with added wine in the proportion of 2/3rds grapes to 1/3rd. added wine the mixtures is then stirred, in the presence of the marc, for a variable period of the order of one hour. The stirring assists the dissolving process by the alcohol of the colouring and other matters characteristic of the red wine contained in the grape skins. Stirring is continued until the desired colouration is obtd the coloured must is then sepd. from the marc and sent to the usual fermentation vats. By sepg. the process of colouring the must red from the fermentation of the must, a better quality wine is obtd. The first process is carried out in the presence of the marc and the latter in its absence. The plant consists of a cylindrical tank with a conical base into which the pips fall. There is an annular filter at the top and a syphon, adjustable for height, through which the coloured must is evacuated. The pips and the marc, which floats to the top, are evacuated to a press.

Title: Packaging machine
IPC: B65B1/04
Filed: 1974-02-26
Abstract: Machine for packaging materials having a low mesh size, in cubic bags of flexible material. Each bag is supported in a rigid-walled cubic enclosure mounted on the door of an hermetically sealed filling chamber and a vacuum or controlled gaseous atmosphere is established and maintained in the filling chamber. The bag is vibrated and filled, under the controlled atmosphere, with the material to be packaged from which gas has been removed. The material falls under gravity from an hermetically sealed degassing and weighing chamber mounted above the filling chamber, passing through a tube into the bag. The neck of the filled bag is heat-sealed under vacuum in the filling chamber by two sealing heads. The sealed, filled bag is then removed from the filling chamber by opening the door and the bag is removed from the enclosure by a suction plate which grips one side of the bag. The bag can be inflated before insertion into the enclosure in order to produce its maximum volume.

Patent ES-438168-A1 (ES)
Title: Percussion fuse for an explosive munitions shell
IPC: F42C15/24
Filed: 1975-06-03
Abstract: An improved percussion fuse for a mortar or similar explosive munitions shell is described. The fuse body that interconnects the charge-carrying shell body with the shell head disposed forwardly thereof has a sleeve portion in which a radial bore is disposed. A conventional impact member that carries the percussion fuse and that is slidable axially within the sleeve has a mating, V-shaped groove that cooperates with the bore in the sleeve to normally retain a locking sphere therein such locking sphere normally prevents the forward movement of the impact member against the primer that is carried at the rear portion of the shell head. An easily puncturable, membrane-like closure member is disposed over the bore in the sleeve portion of the impact member to retain the blocking sphere in its seated position after the shell cartridge has been separated from the shell during the firing operation. During deceleration of the fired shell, the groove in the impact member moves forwardly to cam the captured blocking sphere in a radially outward direction, whereupon the latter punctures the closure member and escapes. Accidental detonation of the fired shell during an initial portion of the shell trajectory is prevented by the provision of a pair of offset recesses in the confronting surfaces of the impact member and the shell head, the radial interface between such recesses serving to prevent the percussion cap in the impact member from contacting the primer.

Title: Rotational rate of change sensor
IPC: B60T8/72
Filed: 1976-02-19
Abstract: A sensor responsive to the rate of change of changing rotational speeds of a rotatable element in which a flyweight is yieldably coupled with the rotatable element through an interconnecting element at any relative rotational position of the flyweight and interconnection for normal rotation thereof at a known ratio of rotational speed while accommodating decoupled rotation of the flyweight upon a change in rotational speed of the driving element at such a rate as to cause a torque in excess of a determinable threshold torque to act between the interconnection and the flyweight. During decoupled rotation, the flyweight is limited to deceleration at a controlled, substantially constant rate. Any occurrence of decoupled rotation of the flyweight is signalled as indicating that the rate of change of the changing rotational speed of the rotatable element exceeds a determinable rate. In the particular instance of an automotive vehicle wheel, the signalled occurrence indicates wheel slip and sensor signals may be used with an appropriate brake modulator for varying braking force.
