Title: Combined control and regulating valve for liquids or gases
Inventor: GLANSK LEIF
IPC: F24H9/12
Filed: 1991-07-10
Abstract: A combined control and regulating valve (1) having a housing (2) with an inlet (3) and an outlet (4) as well as a partition (5) between said inlet and outlet and having a seat (6) designed for an interaction with a main valve body (7), which is adjustable from outside. To said inlet and said outlet are connected a measuring nipple each (50 and 74, respectively) via a bore (30, 31 and 40, 41 respectively) for the measurement and the control of temperature and/or pressure. One of the measuring nipples is designed as a multiple function nipple (50) having a cut-off-valve permitting tapping and filling of the medium, which is to be controlled/regulated. In order to enhance reliability in operation, to provide even more precise and reliable measuring results, to reduce the risk of clogging of the cavities leading to the measuring nipples, to reduce costs for manufacturing and/or fitting, to provide preconditions for various conditions of operation and for partial changes as well as for being able to affect other valve properties, like sealing properties and use of differently designed or dimensioned valve bodies, at least one bore (30, 31) is extended axially to communicate with a so extended portion (110) with a zone of the medium channel (73) downstream of said seat (6) via an area immediately above said valve body (7) or around said seat (6) by means of a casing provided with a groove.

Title: Sun tracking solar concentrator
Inventor: CHAUVET MAXIME
IPC: F24S23/77
Filed: 1993-06-18
Abstract: SUN TRACKING SOLAR CONCENTRATOR                 ABSTRACT OF THE DISCLOSURE      The solar concentrator includes a carriage movable along an inclined, ground anchored ramp.  A first weight at the end of a pulley carried first cable, biases the carriage upwardly of the ramp slope.  A number of mirrors are pivotally carried by the carriage,  and reflect sunrays toward a heat sink absorber.  A second weight biases the mirrors to pivot in one direction, while a third weight biases the mirrors in an opposite direction.  The operator can put into operation the second or third weight as he chooses.  Gravity induced up or down carriage displacement allows sun tracking adjustments on an incremental, day to day basis.   Gravity induced mirrors pivotal motion allow sun tracking adjustments on a continuous basis during each daylight period.   Hence, all year long, solar rays reflected by the mirrors remain convergent toward the absorber.
