Patent ES-334501-A1 (ES)
Title: Press for the manufacture of pressed articles of synthetic plastics formed material
IPC: B29C44/58
Filed: 1966-12-14
Abstract: A press for manufacturing articles of foamed plastics e.g. polystyrene comprises a two part mould 13, 14, Fig. 1, the parts being relatively movable together by fluid rams 12, Fig. 3, and a locking cylinder 21 connected to one of the mould parts (e.g. connected to the frame to which the lower mould part is also fixed) having a locking member engageable with eounterholding means 31 connected to the other mould part (e.g. connected to cylinder 9 of ram 12 to which the upper mould part is also fixed) when the parts are closed together, the connection between the locking cylinder 21 and locking member including a lost-motion mechanism. Thus, on disengaging the locking device and counter-holding means, there is a limited amount of free movement of the locking cylinder 21 before the cylinder 21 moves the locking member out of engagement. As shown in Fig. 3, the locking device comprises a locking piston rod 22 of cylinder (21) carrying a piston 23 reciprocable in cylinder 24 of a further piston 19 which effects the engagement, piston 23 abutting faces 27, 28 of cylinder 24 on withdrawal and extension of piston rod 22.
Patent ES-339124-A1 (ES)
Title: Shock absorbing and static load supporting drill string apparatus
IPC: E21B17/07
Filed: 1967-03-25
Abstract: A shock absorber for insertion into a drill string comprises a tubular member A adapted to be connected to one part of the string, a piston member B reciprocable in the member A and adapted to be connected to the other part of the string, a liquid pressure transmitting chamber E between the members, a gas cavity C in one of the members, and a movable separation element F in the cavity preventing liquid (a lubricant) from the chamber intermingling with the gas in the cavity. The cavity is shown as formed in the member A and the element is a flexible bag to which gas is supplied at the surface through a valve D. The other member (shown as the member B) has a cavity G housing a flexible bag F' to which drilling fluid in the bore-hole is freely admitted. As the string and absorber are lowered into the borehole the increasing pressure of the drilling fluid causes liquid from the part of the cavity G outside the bag F' to pass through a non-return valve 203 into the chamber E and compress the gas in the bag F, the arrangement preventing the absorber shortening under the increasing pressure of drilling fluid. When the bit engages the bottom of the borehole the piston member moves uwardly until the gas is compressed sufficiently to withstand the load applied to the bit. As the string and absorber are removed from the borehole the absorber lengthens and liquid in the chamber'E by-passes the piston seal 131 so that the gas pressure is reduced. The members have a splined connection 233 which transmit torque from the member A to the member B and the bit. In a modification the chamber G and bag F' are dispensed with, the drilling fluid entering the chamber E through a non return valve which may be opened by thrusting a tool down the bore of the string as it and the absorber are removed from a borehole. Alternatively the drilling fluid enters the chamber E through an aperture which is closed by the piston when the weight is taken by the bit.

Patent ES-377909-A1 (ES)
Title: Vehicle suspension device
IPC: B60G17/04
Filed: 1970-03-24
Abstract: In a vehicle suspension unit having a gasfilled chamber 1 combined with a liquid- or gasfilled piston-cylinder unit 18, 15, the gas chamber contains a heating element 4 which, in use, is energized to heat the gas whenever the piston moves more than a predetermined distance into the cylinder. The heating expands the gas and causes the piston to return, thus tending to maintain a constant piston extension. The gas chamber is defined by the upper part 9 of a spherical enclosure 9, 10 and is closed by a diaphragm 7. The lower part 10 of the enclosure communicates with the cylinder 15 but is insulated from it. In consequence, the circuit from an external electric power source (Fig. 2, not shown) on the associated vehicle (which source applies a potential difference between the piston-rod 17 and the terminal 6) is by way of 6, 4, 9, 10, 11, 13 and 17, 18, 26, 22, 24. The gap between the contact 24 on the plunger 22 and the plate 13 in the member 11 will be closed when the piston moves sufficiently into the cylinder: this will energize the heater and expand the unit. Details and modifications disclosed in the Specification include the following: (a) The upper end connection includes resilient and electrically insulating discs 31. The upper end plug 5 is also required to be electrically insulating and removable, for use in a filling technique, which is described in the Specification, (b) The gas chamber has thermally insulating linings 3, 31. These may be white or metalized to reflect heat and the chamber contain a dispersed, preferably black, heat-absorbing powder. Suitable materials for the linings are specified. (c) The heater coil 4 shown may be replaced by a coated (e.g. printed-circuit) coating which may also serve as the heat reflecting means mentioned in (b) above. The possibility of using semiconductor thermo-electric heaters or arc discharge heating is also mentioned. (d) The unit may be used in combination with other suspension springs. In particular, to make the selflevelling action have the same dependence on gas temperature in the more heavily loaded (rear) wheels than the other (front) wheels of a vehicle, the units at the heavily loaded end may be combined with supplementary springs of the requisite stiffness to offset the extra load.

Title: Automatic mobile radio telephone system
IPC: H04B7/155
Filed: 1970-04-02
Abstract: An automatic mobile radio telephone system employs a number of mobile subsets interconnectable through a radio relay station. The station includes two or more duplex channels and marks a selected free channel with a tone fi and transmits at a reduced power. A calling mobile set sends out a tone fd and the relay station in response stops sending tone fi and starts transmitting tone fd at full power. Free sets in standby condition on fi catch fd and wait for the called number. Sets that are not concerned with the call search for another channel marked fi by the station, since the first said channel has been taken by the call. Signals from a set cannot be received directly by other sets, and secrecy of each communication is insured.
