Title: Improvements in or relating to washing machines
IPC: D06F33/48
Filed: 1959-01-01
Abstract: 927,106. Washing and drying machines. WHIRLPOOL CORPORATION. Nov. 29, 1961 [Nov. 29, 1960], No. 42775/61. Class 138 (2). [Also in Groups XIII and XXIV] The subject - matter of this Specification is the same as that of Specification 927,105 except that the transmission unit 26 has three speed ratios instead of two. Intermediate speeds can be obtained by slipping an airpressure-actuated clutch 234a, 132. The transmission unit 26 (Fig. 7) includes two shafts 26a, 26b the first driven by a motor and the second having a pulley 28 to drive the clothes drum. For the low speed drive (for washing) a gear 119 on the shaft 26a rotates a gear 120 freely mounted on the shaft 26b. A threaded clutch drive plate 124 is mounted on a threaded hub 125 fixedly mounted on the shaft 26b and has a peripheral groove holding a spring wire loop 127 which is attached to a pin 128 secured in the gear 120. As the gear 120 rotates, the clutch drive plate 124 is screwed along the threaded hub 125 by friction with the wire loop 127 until diametral protuberances on the clutch drive plate 124 engage with depressions in the gear 120, after which the shaft 26b is driven by the gear 120. For the intermediate speed drive (for spin-drying) the air pressure in a chamber 241a is increased thereby pushing (via a diaphragm member 241) one part 234a of the friction clutch 234a, 132 along the shaft 26a to which it is keyed, to engage with the other part 132 which is fixed to a gear 130 freely rotatable on the shaft 26a. The gear 130 rotates a gear 133 freely rotatable on the shaft 26b, which winds up a spring clutch 134 to drive a gear 135 keyed to the shaft 26b, which is thereby rotated faster than the " low-speed " driven gear 120, thus disengaging the " low-speed " clutch plate 124 by screwing it away along the hub 125. For the high-speed drive (for spin-drying) a solenoid 145 (Fig. 6, not shown) is energized to withdraw, via pivot means, a rod 152 from against a tab 153a on a clutch release ring 153, enabling the gear 130 to wind up a spring clutch 138 and drive a gear 137 which is freely rotatable on the shaft 26a and which meshes with the gear 135 (keyed to the shaft 26b). The gearing ratios are such that the " intermediate-speed " spring clutch 134 is unwound and the shaft 26b is driven at the high speed.

Title: Method and apparatus for isokinetic fluid sampling
Inventor: DYBDAHL BJORN
IPC: G01N1/20
Filed: 1994-12-21
Abstract: The invention relates to a method for the treatment and analysis of isokinetic fluid samples, for, on the basis of the analysis, to optimalize the fluid's speed of flow through a separator (1) for a multiphase fluid consisting of e.g. oil/gas/water, where the gas constituent may contain entrained liquid drops/droplets/particles; it being not desired that gas leaving the separator (1) should contain such entrained liquid. Thus, in order to provide a parameter, upon the basis of which the fluid's speed of flow through the separator can be regulated, the separated gas constituent including possibly entrained liquid drops/droplets/particles is subjected to a temperature/pressure treatment, causing said liquid drops/droplets/particles to evaporate/condense, the resultant gas/steam mixture respectively liquid phase is subjected to a density measurement for subsequent analysis. Regulating said separator's speed of flow while fluid samples are density-tested until a low density value has been achieved, one has produced an optimum speed of flow, corresponding to maximum utilization of the separator. The apparatus comprises a container (8) which is heatable/coolable, for thus to cause liquid drops/droplets/particles entrained in the gas constituent to evaporate respectively condense, the container (8) through a discharge line (13) being coupled to a density measuring device (14 respectively 23).
