[Also in Divisions F4 and G3] In an automobile air-conditioning system comprising a compressor 11, condenser 12, receiver 17, expansion valve 20 and evaporator 13 over which air is passed by a blower, the return conduit 16 includes a valve 21 responsive to the pressure in conduit 16 and the evaporator temperature, the valve 21 being actuated at 22 by a vacuum derived from the engine inlet manifold and controlled by pilot valve 23. The latter comprises (Fig. 3) a lever 37 pivoted at 94 by ears integral therewith and biased counterclockwise by tension spring 40 so that a resilient part 110, 111 of the lever engages a crosspin 80 connecting fingers integral with washer 72, these fingers passing through apertures in diaphragm 67. The latter is thereby biased to the position shown in which pad 70 is seated on the central bore of washer 72 and unseated from post 48 to connect the vacuum source at 53 to chamber 22 of valve 21 via chamber 43 and nipple (55). At a given vacuum level in chamber 43 diaphragm 67 seats on the end of post 48. Any excess vacuum in chamber 43 is relieved by further leftward movement of the diaphragm to unseat pad 70 from washer 72. The level of vacuum in chamber 22 is varied by adjusting the loading of spring 40 via knob 27, cam disc 146 and lever 142. Additionally, the level of vacuum in chamber is controlled by thermally responsive unit 36 which senses evaporator temperature and acts on lever 37 via plunger 87. Calibration adjustment is made by screw 113, which positions pin 80 via part 110, 111 of lever 37, and by screw 157 which varies the number of turns of spring 40 engaged on nut (160). Knob 27 is calibrated to indicate selected air temperature.

Abstract: An adhesive coated sheet material has an adhesive coating which comprises a layer of pressure-sensitive adhesive covered by a particulate layer of a dry powdered adhesive which is activated when wetted with an appropriate solvent, e.g. water.  The powdered material may be polyvinyl alcohol, or water-soluble cellulose derivative, shellac, ethyl cellulose, polyvinyl acetal or cellulose nitrate.  The sheet material may be of a thermoplastic resin examples of which are given and a primer coat examples of which are given interposed between the surface of the sheet and the pressure sensitive adhesive.  The coating weight of pressure sensitive adhesive may be from 0.3 to 1.0 oz/yd2 and of powdered material up to 1 oz/yd2.  The dry powdered material substantially all passes a 100 BSS mesh sieve.  The adhesive coated sheet material may be prepared by coating a base sheet with a pressure sensitive adhesive and applying a dry powdered solvent-activatable adhesive to form a particulate layer covering the surface of the pressure sensitive adhesive.  The sheet material may be stuck to a surface by wetting the adhesive coating with an appropriate solvent, e.g. water, to activate the powdered adhesive, applying the sheet to the surface with the still wet layer in contact with the surface and allowing the solvent to dry out.  The pressure sensitive adhesive may be based on synthetic or natural rubber.
