Patent ES-344409-A1 (ES)
Title: Thermostat
IPC: F01P7/16
Filed: 1967-08-24
Abstract: A temperature responsive actuator for a valve 13 comprises a heat-conductive chamber 10 in which is disposed a guide 18 for a push-rod 23, the remaining space in the chamber 10 being filled with a thermally expansible material 22, e.g. wax, to push the rod 23 outwardly from the chamber 10 and open the valve 13 against the action of a spring 12, a plug 20 of rubber or other resilient material being interposed between the expansible material 22 and the rod 23 to seal against the guide 18 and prevent leakage of the material 22. The guide 18 has an end portion which is held in place by a flange 17 integral with the walls of the chamber 10. An anti-chafing disc 25 of plastics material is interposed between the plug 20 and the end of the push-rod 23, the end of the plug 20 contacting the material 22 preferably having a convex shape, and the plug being shaped to have an enlarged diameter at this end, so that it has to be compressed radially to force it into the guide 18. This assists the sealing action of the plug 20. A ring seal 27 held in place by a disc 28 provides a seal between the push-rod 23 and guide 18, the push-rod 23 being secured, adjustably as shown, or by riveting to a bridge member 6 on a housing 1 in which is formed a seat 5 for the valve 13. After repeated use and when the durability of the plug 20 has come to an end, the valve 13 is arranged to remain open since at this stage the ageing of the plug will increase the friction between the plug 20 and the guide 18 to such an extent that the friction will overcome the effect of the spring 12 tending to close the valve which will thus remain open.

Patent ES-347023-A1 (ES)
Title: Electronic heat regulation
IPC: G05D23/24
Filed: 1967-11-10
Abstract: In a temperature control system for a hot plate or a mashing machine, the heater wire is utilized as a temperature sensor by measuring the current through it. A triac 8 controls a heater 6, the current through which is measured by the volt drop across a resistor 9, or a transformer (not shown), and a volt drop being passed through a diode D1 to a resistor R2 connected to one side of a differential amplifier T1, T2, which through a threshold amplifier T6, T7 switches off the triac at a determined temperature. Initially the switch off point is determined by a polentiometer R7, R8 through a diode D2. A NTC sensor R9 in contact with the heater casing connected to another differential amplifier T3, T4 takes over the control of T1, T2 through a diode D3 at another determined temperature, hence lowers the temperature at which the triac 8 is cut out. Superimposed on the input of amplifier T6, T7 are synchronizing pulses from a circuit W3, R19, D4, C1 which ensure that triac 8 is only switched on at a voltage of zero. In a modification Fig.9 (not shown) the triac 8 is switched on by a monostable multivibrator (T9, T10) a triac (t 1 ) Fig.2 (not shown) determined by a CR circuit (C4, R27) after switching off. In an alternative circuit Fig.10 (not shown) an estable multi-vibrator (T8, T9) ensures that the triac 8 is switched on at regular intervals (t2) Fig.3 (not shown). The arrangement may be controlled by a cooking or washing programme switch which may reduce the set temperature as the desired temperature is approached. The time intervals (t1, t2) may be short. Additional temperature sensors may be employed and the mean, or an extreme value compared with the datum. The resistance of the heater may be derived when the heater is switched off by means of an additional resistor (12) Fig.4 (not shown). The system is stated to have the advantage of switching off an immensed heater e.g. in a washing machine, should the heater became unimmensed.

Title: Marine fenders
IPC: E02B3/26
Filed: 1972-01-18
Abstract: A marine fender for use on dock walls and at lock entrances comprises a wheel equipped with a pneumatic tire and mounted on a vertical axle in a supporting structure. Two rollers are mounted on vertical axles in the supporting structure, and the wheel axle can slide at right angles to its own length to allow the tire to be pressed into resilient deforming engagement with the rollers. This inward movement, and the return movement, of the wheel are yieldingly resisted by hydraulic rams attached to the wheel axle, and the flow of the hydraulic fluid of the rams during the instroke of the rams is controlled by a control device incorporating a restrictor the effective restriction of which is reduced as the instroke proceeds. This causes a rapid increase in the fending force exerted by the wheel during its initial inward movement, and a subsequent levelling off of this force as it approaches its maximum permissible value during the remaining part of the inward movement.
