Abstract: 1,099,933. Valves. WALTON ENGINEERING CO. Ltd. June 14, 1965 [June 22, 1964], No. 25797/64. Heading F2V. In a valve for controlling the temperature of cooling liquid or oil in large ships, diesel engines, e.g. of 20,000 to 30,000 h.p., the liquid issuing from the engine to a port 17 is divided between an outlet 16 to a cooler and a cooler by-pass outlet 15 or, alternatively, liquid returning to the engine via port 17 is mixed from ports 15 and 16 which are controlled by a pair of arcuate shutters 14 carried by a rotor 12 which is rotated on spindle 27 by two series coupled pairs of wax-filled thermostat elements 32, 35 which act on a thrust plate 39 attached to a cross-link 40 (Fig. 2, not shown), connecting between two pairs of levers 19 and links 18 which are connected to a pair of rotor webs 13 via swinging fulcrum links 23 pivoted on brackets 25 integral with collar 26 fixed to the spindle 27. A thermostat holder (28), (Fig. 3, not shown), is also fixed to the collar (26) and a pair of tubular extensions (29) thereof slidably receive the barrels (31) of one (32) of each pair of thermostat elements and are threadedly engaged at their ends with the barrels (34) of the other (35) of each pair of thermostat elements so that the thermostat plungers (36) abut within the extensions (29), whereby the combined thermal expansion of each pair of thermostat elements, acting against a pair of concentric return springs 44, 45 abutting between holder 28 and collar 46 connected by plates 47 to a collar 43 fixed to the heads 38 of elements 32, is transmitted to thrust plate 39 by a heavy spring 41 which acts as an over-ride spring if the rotor 12 jams, whereupon bolts 37 formed as extensions of the thermostat heads 38 are displaceable through the plate 39. In an alternative embodiment (Figs. 4 and 5, not shown), four pairs of the thermostat elements (32, 35) act upon a thrust plate (139, 153) forming a socket for a ball link connection to a lever (19) pivoted about an arm (123), integral with a collar (126) fixed to the spindle (27), and connected by a link (18) to the rotor web 13. A plurality of independent rotor sections 12 may be employed with elongated ports 15, 16 and 17. The spindle 27 may also have a radially-extending handle for manual operation of the rotor.

Title: Protective sleeve for underground cables - snaps over cables to provide protection and to prevent heat-insulating air pockets
IPC: H02G9/02
Filed: 1981-04-23
Abstract: When electric cables are buried in the ground, they are often covered by a protective plate before the earth is 'back-filled'. This can leave air-pockets which act as heat insulators, causing the cable to overheat. The present protection sleeve fits snugly over the cable, and is made of heat-conductive material. The protective sleeve (1) has a circular cross-section (2) except at the bottom where two radial flanges (3) stick out. When the cable has been laid in the trench, the sleeve is snapped over it and the earth is replaced in the trench. It can be equipped with metal re-inforcing for extra protection, and with holes in the wall to allow water to enter to make a good thermal connection.
