IPC: G01K5/32
Filed: 1970-04-07
Abstract: 1302387 Temperature responsive devices DANFOSS A S 7 April 1970 [28 April 1969] 16453/70 Heading G1D A temperature sensor 10 for use in controlling a thermostat in a room comprises a surface so constructed that the sensor responds in accordance with heat radiation from the surrounding environment and with convection currents to actuate the thermostat such that a predetermined relationship between radiation temperature and convection temperature in the room is substantially maintained. The sensor which may contain a temperature responsive fluid may be connected by way of a capillary tube 11, Fig.3, to a chamber 12 defined partly by a flexible bellows 13 which is adapted to urge a closure member 17 of a valve 15 against the bias of a spring 18 towards a valve seat 16 in accordance with increases in temperature so as to control the valve 15 which forms part of a fluid heating system. The sensor may be ellipsoidal, cylindrical, spherical or of boxlike shape and constructed such that the surface areas exposed to heat radiation and convection bear a predetermined relationship to each other which is selected on the basis of thermal properties of such areas. In one example the sensor 20, Fig.4 comprises a substantially closed cylinder having on its outer surface zones 21 for absorbing heat radiation and zones 22 for reflecting heat radiation; in another example a hollow cylinder is arranged such that the inner wall thereof is sensitive only to convection whereas the outer wall is sensitive to both convection and radiation; and in yet a further example the sensor which is substantially spherical and arranged to be supported against a wall of a room is provided on one semi spherical portion nearest the wall with a radiation reflecting surface and on the other semi spherical portion with a radiation absorbing surface. Other examples are described in the Specification.

A disconnectable pipe coupling, connecting brake &c. pipes of a tractor and trailer, in a system employing fluid at a pressure other than atmospheric pressure, comprises complementary male and female coupling elements which are guided one into another by means of a guide member on the female element, which is mounted on a resilient cantilever support permitting limited element movement in all directions from a central position. As shown in Fig. 1, the guide member constitutes a cone 35, and the cantilever support comprises a helical, conical spring 37 held in compression between the outer end of the female coupling element and a rigid mounting 36 on the tractor. The spring 37 can be replaced by an elastic mass with similar elastic properties. The male element 38, mounted on the trailer, enters the cone 35, centralizes the female element on compressing the spring 37, thus allowing freedom of movement of the female element by pushing a plate 45 away from the rigid mounting 36, see Fig. 2 (not shown), and presses against a valve 32 against the action of a valve spring, opening the valve, allowing fluid to pass through holes 40. The coupling is sealed by a rubber ring 41.
