Patent ES-312186-A1 (ES)
Title: Die casting machine
IPC: B22D17/26
Filed: 1965-04-23
Abstract: A die-casting machine of the gooseneck type has dies 20, 22, Figs. 3 and 4, which are mounted for reciprocating movement in guide means 28 supported on the machine frame. Means for delivering molten metal into the dies includes an injector assembly 84 which is pivotally mounted on the frame so as to bring the nozzle 94 into and out of engagement with a passage 164 in the dies. Means for aligning the nozzle 94 of the gooseneck 86 with the die passage 164 is provided by adjusting screws 118 which actuate on the arms 110 and 112 on which the gooseneck is pivotally mounted. The operational movements of the dies, the injection assembly and the injection plunger 174 are actuated by pneumatic piston and cylinder units 54, 100 and 180 respectively. Separate cooling means are provided for the dies, gooseneck and for the support plate B of the machine frame. Means for adjusting the die positions is provided in the form of a knob and lock-nut 66, 65 and a screwed sleeve 72 which is adapted to engage the lever mechanism 44 which actuates the dies, each die being adjusted independently. In the embodiment described, two die members 20, 22 and two core members 24, 26 are shown, but the operation is the same for each. The core members are positioned at right-angle to the die members, the guide means 28 being in the form of a cruciform member. Within the gooseneck of the injection assembly is positioned a check valve 192 to control the suckback of molten metal from the die and the influx of air into the gooseneck. An air line 204 attached to the gooseneck is provided to blow the finished casting from the die at the completion of each operation. The operation of the machine may be effected manually or automatically.

Title: Method of producing magnesia of desired composition from native magnesite
IPC: C01F5/06
Filed: 1967-08-21
Abstract: Technical magnesia is manufactured by caustic calcination of a magnesite of suitable SiO 2 and Al 2 O 3 content and subjecting it to the action of hydrogen chloride gas, in the absence of combustible or reducible gases, at a temperature between 800 and 1100 C., iron and manganese being converted to volatile chlorides, whilst calcium is converted to its chloride which remains in the material to give an intermediate product which by a post-treatment of the residual chlorides is converted to technical magnesia of the desired final composition and at least a part of the hydrogen chloride used is recovered from the volatile chlorides. Products of the process which are practically free from iron and manganese may be (a) more than 97% by weight MgO with SiO 2 and CaO, (b) more than 94% by weight MgO with CaO and SiO 2 less than 5% by weight in a weight ratio either greater than 2 to 1 or less than 1 to 1 respectively. The CaO and SiO 2 content is preferably less than 4% by weight. The post-treatment comprises an oxidation of the residual chlorides by means of steam. The amount of calcium in the product may be regulated by leaching out a part or all of the calcium chloride present prior to the steam oxidation. The recovery of hydrogen chloride is carried out using known methods.

Patent ES-349703-A1 (ES)
Title: Reed relay switching network
IPC: H04Q3/00
Filed: 1968-01-24
Abstract: In a multistage switching network in which each matrix of one stage is connected via one link only to a matrix of an adjacent stage and each matrix has an associated marking relay which is brought up (when a path has been selected) preparatory to the switching-through of this path, each link includes two control wires, the marking wires of like-numbered rows of the severed matrices in a stage are multipled and each crosspoint relay has a series make contact with a diode connecting the junction of the relay and contact to the associated row marking wire. A crosspoint relay is operated by apply ing potentials to the relevant control and mark ing wires, the values of the potentials used at each stage differing from those in the adjacent stages by an amount equal to the operating potential of a crosspoint relay. Operation.-A preselected path between U2 and U1 via matrix KVB2 in the second stage is set-up by operating matrix marking relays HA1, HB2 and HC1, closing contact k (junctor side) to apply + 12 V to the outlet U1 and closing contact EM to apply - 24 V to the inlet's row marking wire ma1. Contact ha13 extends -12 V over the second control wire eb2 of link ZL2 (and also over eb1 of link ZL1 but this is irrelevant) so that link marking relay BB1 comes up in stage B (contact hb21 is closed because HB2 is up). The - 12 V is extended back over link ZL2's first control wire cb2 via rectified G121 whereby KPA2 operates to switch through the speech wires (not shown) and to close its self-holding contact kpa2. In stage B with BB1 up, - 12 V is applied to row marking wire bb1 so that KPB1 can be energized due to the simultaneously occurring earth on the second wire ecn (and hence also the first control wire ccn) of link ZLn. The earth on ecn additionally brings up CB2 in order to provide earth to the row marking wire mc2 and hence operate KPC3. The above processes occur vertically simultaneously. The crosspoint relays KPA1, KPB1 and KPC3 hold from a potential U2 (more negative than - 24 V) to a potential U1 (more negative than earth), the matrix and row marking relays HA1, HB2, HC1 and BB1, CB2, and the contacts k and EM then being released. It should be noted that the crosspoint relay operating potentials for stages A B and C are respectively - 24 and - 12 - 12 and earth and earth and + 12 V, i.e. the potentials in each stage differ by 12 volts from those in adjacent stages, 12 V being the potential required to operate a crosspoint relay. In an alternative embodiment (Fig. 2, not shown) the diodes, e.g. G21, G121 connected to the inlet end of each link are dispensed with, operating potential for a crosspoint relay in the preceding stage being reverted over the links first control wire by connecting the latter to its associated row marking wire via a contact of the matrix marking relay.

Patent ES-447592-A1 (ES)
Title: Flexible coupling and torque-transmitting element therefor
IPC: F16D3/62
Filed: 1976-05-05
Abstract: The driving coupling member and the driven coupling member of a flexible coupling are tied together by a plurality of flexible torque-transmitting members which are arranged in a circular pattern. Each torque-transmitting member consists of an endless, substantially elliptical loop of an elastic material, e.g. rubber, which may be re-inforced by an appropriate woven material. Resilient inserts are placed into the elliptical cavities defined by the torque-transmitting members, and these inserts are compressed when the torque-transmitting members are elongated as a result of the transmission of torques between both coupling members. The aforementioned resilient inserts expand when the amount of torque transmitted is reduced. The expansion and contraction of the aforementioned inserts are transmitted to containers of a fluid medium and cause said fluid medium to flow out of a contracting container into another container. The flow of fluid is controlled by a restricted orifice. As a result, the flow of fluid exerts a controllable shock-absorbing damping action upon the flexible coupling. The aforementioned torque-transmitting members are supported by studs, or bolts, projecting from the driving and driven member, respectively, of the flexible coupling.
