Patent ES-340732-A1 (ES)
Title: Reversible pump turbines
IPC: F03B15/18
Filed: 1967-05-19
Abstract: and FIT. In a hydraulic turbine or reversible pumpturbine having adjustable guide vanes programmed to close automatically so as to stop or substantially reduce the flow of water through the machine in the event of an abrupt cutting off of the load on the machine during use as a turbine, the vane closure programme comprises a first phase during which the vanes are moved relatively quickly towards their closed positions, but do not completely close, a second phase during which they are at least partially re-opened, and a third phase during which the vanes are moved relatively slowly towards their closed positions. This prevents severe oscillation of the water pressure in the penstock and in the hydraulic machine which would occur if the vanes were closed abruptly. In the first phase, the vanes may be turned through 75% - 85% of the total movement between the fully open and fully closed positions, and in the second phase they may be re-opened to approximately the half-way position (or may even be fully opened). The closure programme may be initiated in response to the cut in the current flow through the electric generator driven by the turbine (as by a solenoid controlled servo-mechanism) or in response to the resultant rise in turbine speed (sensed by a governor).

Title: Sheet tensioning and transfer mechanism for presses
IPC: B41L19/00
Filed: 1967-09-08
Abstract: A transfer cylinder comprises gripper means for receiving the leading edge of a sheet, and sheet-engaging means for the trailing edge of the sheet, wherein mechanical means are operative to remove the sheet-engaging means towards the grippers around the periphery of the cylinder to receive a sheet and then to move the sheetengaging means away from the gripper to tension the sheet. The cylinder is especially applicable as the second transfer cylinder of the press disclosed in Specification 735,477, where the sheet-engaging means comprise at least one suction head. Fig. 2 illustrates the leading edge 30 of a sheet 32 engaged by gripper 14 while the trailing edge 36 is about to pass from the first transfer cylinder 34 over suction head 20 vacuum is applied and wrinkles 38, 40 in the sheet are removed by swivelling arm 24 in a clockwise direction to draw the sheet taut. The vacuum and the movement of the arm 24 is cam-controlled with the aid of a resilient bias, springs causing the clockwise movement of the arm 24. When it is required to release the trailing edge of the sheet for transfer to a third cylinder, air under pressure is applied through the suction head (Figs. 5-11, not shown). Alternatively, the cams can be replaced by electromagnetic actuators (Figs. 12, 13, not shown).
Patent ES-345359-A1 (ES)
Title: Power Supply Device
IPC: H02H1/06
Filed: 1967-09-22
Abstract: An arrangement for permitting the delayed opening of a circuit-breaker having contacts 3, 4 and a normally energized release coil 5, on the failure of the main supply, comprises a battery 25 to maintain the energization of the coil for a period determined by a timing device 27. As shown the device 27 is a relay, which with the coil 5 is normally energized from the main supply through a transformer 19 and a rectifier 23. When supply failure occurs, a relay 28 releases causing its contacts 28a to interrupt the circuit for the relay 27. At the end of the timed period, the contacts 27a of the relay 27 open to interrupt the supply from the battery 25 to the coil 5 so that the circuit-breaker opens. The battery 25 is charged from the rectifier 23 under the control of a transductor 26 having its control winding in series with the coil 5. A push-button switch 7 when closed causes the relay 27 to be energized to complete the circuit for the coil 5 and the circuit-breaker can then be closed by a manual control 6. In a modification, Fig. 3 (not shown) the relay 28 may be omitted, the relay 27 being normally energized from a tertiary winding on the transformer 19.

Title: Foundry moulding sand compositions
IPC: B22C1/16
Filed: 1969-07-24
Abstract: A foundry moulding sand composition comprises a particulate refractory material admixed with an aqueous fluid, which fluid comprises, in solution, or in stable suspension or dispersion, an alkali metal silicate, a water-soluble oxidizing agent compatible with the metal silicate, and from 9-40%, by weight, on the weight of the fluid, of a readily oxidizable organic material, which is compatible with the alkali metal silicate and the oxidizing agent. The alkali metal silicate used is preferably sodium silicate and of these that having a SiO 2 : Na 2 O weight ratio of 2À0- 3.3 is advantageously used. The aqueous fluid preferably contains from 50-80% by weight, particularly 60-75%, of the commercial sodium silicate solution, whilst the amount of oxidizing agent is preferably 1-15% by weight. The water-soluble oxidizing agent should be compatible with the alkali metal silicate in the sense that it does not prevent the alkali metal silicate from exercizing its function as a sand binding agent and examples of such oxidizing agents are the nitrates, chromates, dichromates, permanganates and chlorates of alkali metals, particularly of sodium and potassium. Mixtures of such agents may be used. Examples of the readily oxidizable materials are starches, dextrine, celluloses, gums, natural resins, sugars and carbohydrate materials, ligneous materials, synthetic polymers, e.g. polyethylene and polystyrene, and hydrocarbon materials, e.g. coal-tars pitch and wood tars and these materials may be used separately or in admixture. Sucrose is a preferred material and a preferred composition includes sucrose and a mixture of a major proportion of sodium chlorate and a minor proportion of sodium dichromate as the oxidizing agent. The aqueous fluid preferably contains from 6-10% of added water but percentages above or below this range are also envisaged. The term # and is used to cover particulate refractory materials in general, e.g. silica, zircon, chrome, olivine or sillimanite. The aqueous fluid may be added to the sand in a wide range of proportions, e.g. 2-8 parts by weight per 100 parts by weight of sand. Small amounts 0À5-2À0% by weight, of bentonite and soluble dextrine may be added to the sand to improve its green strength.
