Abstract: 1396778 Hydraulic circuits A F HYDRAULICS Ltd 28 March 1973 [28 March 1972] 14583/72 Heading F1P In a hydraulic circuit e.g. for a road drill, a quick warm-up of the hydraulic fluid is ensured by a pressure relief valve 19, Fig.1, which, when the fluid is cold and viscous and therefore under higher than normal pressure, by-passes fluid to a small chamber 14 within the main reservoir 15. Thus, only a small volume of fluid is initially warmed up. At the desired operating temperature a thermostatically controlled by-pass valve 23 in a return line 13 closes, so that fluid is diverted through a cooler 21 adjacent a thermostatically controlled fan 22. From the cooler fluid returns to the larger reservoir. Fig.2 (not shown), illustrates a similar circuit in which a thermostatic element in the small reservoir 14 controls the valve 23. In Fig.3, a restrictor 27 controlled by a thermostatic element 26 restricts fluid-flow increasingly as the temperature decreases. Fig.4, shows an arrangement in which a spring-loaded shuttle-valve 28 with two loads controls both by-pass circuits according to the viscosity of the fluid.

Abstract: 110,573. Howard, F. W. Oct. 23, 1916. Ribs; top-notches; joints; open-caps.-Relates to umbrellas of the type that have ribs constructed with flexible portions near the stick end of the rib to enable the umbrella to be opened. According to the invention, the ribs are so secured to the stick that parts of the ribs are forcibly retained in gripping contact with the stick. The object is to provide an inexpensive frame which may have a paper or other inexpensive cover applied thereto. The flexing part may bo a flattened extension 26, Fig. 5, or 119, Fig. 18; or may consist of a coil 90, Fig. 13. The flattened extensions 26 are caused to bite into the wood of the stick by the pressure of a crown sleeve 25. An appliance for fixing the parts is described. Burrs may be punched in the material at 29 to prevent slipping of the parts. The flattened extensions 26 of the ribs may be spot welded to a strip 70, Fig. 6. A length of the strip carrying six ribs is cut off and 'bent round the stick by rollers in a hand lever press described. The ribs and sleeve may be united by casting the sleeve in a mould into which the rib ends are held. The end of the sleeve may be flared to allow free flexing of the ribs. In the construction shown in Fig. 13, two ribs are formed by one piece of wire 92 having coils 89, 90 for flexing, and a coil 87 for gripping the stick. Two other similar pieces set at the proper angles complete, the frame. In the arrangement shown in Fig. 17, hooked extensions 103 of the ribs fit notches in a sleeve 97. Fig. 18 shows an arrangement having flattened flexing parts 119 and coils 117 to grip the stick.
