Abstract: A test for an electronically controlled braking system, such as an adaptive braking system, is made to assure that the solenoids of each of the modulators are properly wired. According to the test, each modulator is tested in sequence. The exhaust solenoid of a modulator is actuated for 10 milliseconds, and the hold solenoid is then actuated for 30 milliseconds. If the modulator has been miswired, the exhaust solenoid will have been actuated for 30 milliseconds, thus generating a much louder "popping" sound than that generated by the other modulators will be immediately noticed and corrected.

Abstract: Cosmetic formulations have activatable dormant pigments dispersed in an anhydrous base or vehicle. Shear forces applied to the cosmetic formulation following application to the skin causes activation of the dormant pigment thereby releasing the pigment and giving the original color of the anhydrous base or vehicle renewed intensity or a "long wearing" affect.

Abstract: A proportional modulator includes valve elements actuated by a proportional solenoid that controls communications between an inlet port, an outlet port, and an exhaust port. The pressure level at the outlet port is controlled to vary directly with the current applied to the coil of the solenoid controlling the valve elements.

Abstract: A method of controlling biofouling in a aqueous systems comprising introducing into the system a biocidally effective amount of a water soluble perhalide of the formula: ##STR1## where R.sub.1 and R.sub.2 are hydrogen, hydroxyethyl, alkyl, cyclic alkyl, (alpha, omega)-alkyl, alkyl ether, polyether, heterocyclic ring-substituted alkyl, and halogenated alkyl; n is 2 to 6: X is chlorine, bromine or iodine; and only one of R.sub.1 and R.sub.2 may be hydrogen.

Abstract: A barbeque having, for example, a heat source in the form of a gas burner, is provided with a device which permits smoke flavoring of food cooked on the barbeque. Wood chips are contained in a drawer which is received by a complementary sleeve located between the heat source and a cooking grill of the barbeque. During cooking the wood chips are heated by the heat source and the air flow through the drawer is restricted so that the wood chips give off smoke without igniting. The smoke flows about and flavors the food being cooked on the barbeque. Access to the sleeve and the wood chip drawer may be gained through a side wall of the barbeque body and thus the supply of wood chips may be replenished without interfering with the cooking operation. Means is provided to control the volume of smoke produced by the device.

Abstract: This invention provides a portable barbeque having a base and a lid hinged to one another. A pair of allochiral feet are hinged to the bottom of the base and are arranged to lock to the base when deployed to support the base so that there is little likelihood of upsetting the structure. After use, the lid is closed and the feed can be dislodged and folded over the lid to hold the lid closed against the base and to store the feet. This invention also provides a base and a lid and a heat source contained in the base with grill support means inside the base. A shelf is supported in the base and has dividers between sections of the shelf to restrain movement of inert cinders placed on the shelf. A grill also supported by the base is spaced from the shelf such that the cinders are retained by the grill on the shelf should the housing be tilted or turned upside-down.

Abstract: This invention provides a device for meeting the demand of a forced-air furnace for make-up air in a building, the make-up air being available from a duct leading from outside the building. The device takes warm air from the hot air plenum of the furnace and returns the air to the return air plenum. This flow of air is caused by a differential pressure between the two ducts when the furnace is operational and operates a valve element which normally closes the duct carrying outside air and opens to permit flow of this air in response to the passage of warm air between the hot air and return plenums.

Abstract: This invention provides a support for a tubular humidifier pad such that the pad can be replaced easily and efficiently. This is achieved by providing a support having a movable end which can be collapsed to release the pad which is carried on axial stringers attached to this end. The stingers deflect radially inwards so that the old pad can be removed over the collapsed end and a new one put in place. The procedure is then reversed to hold the pad on the support.

Abstract: A lifting and carrying device for flower pots is formed by a generally vertical main support post or bar with a pot supporting member at its lower end and a pair of gripping jaws actuated by a lifting and carrying handle pivotally secured to the upper end of the post. The jaw mechanism is formed by a fixed jaw on the post for engaging the upper rim of the pot on the outside surface and an inner jaw swingably mounted on the post and actuated by a linkage mechanism connected to the handle for engaging the upper rim of the pot on the inside surface. As the handle is lifted, the jaws grip the upper rim of the pot and the pot is lifted for carrying.
