Abstract: ABSTRACT        In a clothes dryer, the electrical resistance of wet articles and the  temperature of exhaust air are monitored electrically.  At the instant the monitored resistance reaches a predetermined value, the time-varying rate of the change of the monitored temperature is detected, to estimate the period of time for which the dryer operation is to be continued.  At the end of the estimated time period, the heat cycle of the dryer is shut down.

Abstract: ABSTRACT OF THE DISCLOSURE         A rack for a plastic bag has its back adjustably mounted by a pair of attachment devices on the undersurface of a hinged panel which normally covers a well provided on the table top of a checkstand in a supermarket.  When a checkout clerk at the checkstand starts to work without a bagboy assisting her, she swings the panel into a upright position and lowers it into a guideway provided on the rear of the well, and then moves the rack to an elevated position on the pair of attachment devices.  This enables the handles of a plastic bag to be placed over the side support arms of the rack so as to suspend the bag in an open position in the well to facilitate the clerk placing items therein as they are rung up on the register.

Abstract: ABSTRACT:          Arrangement provided with a DC/AC converter for igniting and feeding a gas- and/or vapour discharge lamp.         The invention relates to an arrangement provided with a DC/AC converter (10, 11, 13-66) to which a dis-charge lamp (81) is connected. The lamp is shunted by a re-lay contact (90) to obtain an electric circuit through which two electrodes (83, 84) of the lamp can be pre-heated.       In an arrangement according to the invention, it is ensured that the relay contact (90) is closed before a voltage occurs between the electrodes (83, 84) of the lamp (81). Thus, it is avoided that the lamp exhibits a transient flash at too cold electrodes. A timing circuit (40-47) ensures that the contact (90) remains closed for about 1 second, after which the lamp (81) ignites at warm electrodes. No electrical losses occur in the relay (30) during operation of the lamp (81).

Abstract: Abstract Venting gas flow from a fuel tank or the like enters through tangential inlets into a spin chamber,  influencing a closure ball in said chamber to spin or orbit around an upper  conical  wall  portion  of  the  spin  chamber.   The spinning action keeps the closure ball from seating in an outlet opening formed at the upper end of the spin chamber.   The closure ball does seat in response to liquid rising in the spin chamber or tilting of the spin chamber beyond a predetermined angle of tilt.   A vibrating mass positioned on the outlet side of the outlet opening includes a central striker portion which contacts the closure ball whenever it tends to seat in response to shock forces or some condition other than the presence of liquid activated buoyancy forces or tilt activated gravity forces.

Abstract: ABSTRACT         A differentially coated, galvanized steel strip is produced by hot dip coating both sides of a steel strip and adjusting the weight of coating metal on opposite sides of the strip to produce a light coated side and a heavy coated side.  The strip is then precooled to fully solidify the heavy coated side following which the galvanized strip is subjected to a treating step in which simultaneously the light coated side is heated and the heavy coated side is cooled.  This fully transforms the light coated side to iron-zinc alloy throughout while only partially transforming an inner layer on the heavy coated side to iron-zinc alloy.          The outer layer on the heavy coated side consists entirely of coating metal, and there are no intermittent bleed-throughs of iron-zinc alloy to the outer surface of the heavy coated side.

Abstract: Abstract This invention permits the transfer of heat from the exhaust air of a building to incoming fresh air by directing counter flowing air currents on either side of a membrane.  Movement of air is controlled by remotely mounted fans and dampers.            The basic principle of the exchange of heat from the air on one side of a membrane to the air on the other side is common to many air-to-air heat exchangers and it is accomplished by directing the flow of air over a large area of membrane.
