Abstract: 1359120 Fluid-pressure servomotor systems UNIVERSAL PNEUMATIC CONTROLS Inc 1 Nov 1972 [13 Jan 1972] 50359/72 Heading G3P [Also in Division G1] A thermostat for controlling a heating system which includes a pneumatic actuator connected to a flow valve in an air duct, comprises a bimetal strip 96, mounted on an adjustable hinged arm 64, the strip 96 being separated from a bleed orifice 98 by a variable amount which is determined by the angular position of a cam 40 which abuts a set screw 38 on the arm 64 at an arcuate cam surface 82. The volume of air passing through the orifice 98 from a pressure source, and hence the volume of air flowing through the air duct, is therefore determined by the strip 96 position. After setting a temperature by cam 40 rotation, external temperature variations affect the strip 96 position causing a counteracting change in the air-flow through orifice 98. Air from the pressure source also enters a calibration chamber 118 via an orifice 120 Fig. 5, the resulting pressure therein controlling the position of an indicator pin 34 which becomes visible through an aperture 24 at a predetermined pressure level. Thermostat calibration is effected by setting the cam 40 to the position corresponding to that measured by a thermometer 136, and adjusting the arm 64 position by rotating the screw 38 until the pin 34 becomes visible.

The sheet may be formed using a dry or wet forming process. Typically, polypropylene fibres may be dispersed together with a binder (e.g. polyethylene oxide or a saponified compound of a vinyl acetate polymer or copolymer, or acetal thereof), in water, the dispersion wetlaid to form a sheet, the sheet heated to cause shrinkage, and the binder washed from the sheet. The binder may be added in the form of a powder or fibres. Alternatively, the fibres may be dispersed in an organic solvent to form a dispersion, which is wet-laid to form a sheet, the sheet being heated to cause the fibres to partially dissolve in residual solvent and to fuse them together. Sheets, thus obtained, after drying may be frictionally calendered by passage between a pair of rolls each of which rotates at a speed different from the other. Conventional calender rolls composed of an elastic roll e.g. paper or rubber roll and a steel roll may be used. Polyethylene fibres having a density of from 0.955 to 0.97 g/cm<SP>3</SP> or polypropylene microfibres of 2-10Á average fibre diameter and having an extractable content in decalin at 77‹C of less than 15% by wt. may be incorporated in the sheet of polypropylene fibres. Alternatively the polyethylene fibres may be incorporated in the form of bicomponent fibres with the polypropylene fibres. The sheet may be washed with an appropriate solvent before and/or after frictional calendering. Examples 1, 2, and 4 describe the formation of fibrous polypropylene sheet material using dry forming methods involving needling. The other Examples describe the use of wet-formation techniques, some of which involve the use of carboxymethyl cellulose and fibrous polyvinyl alcohol as binders together with surfactants.
