Abstract: An aerosol actuating cap is disclosed for use with an aerosol container having a tilt valve. An actuator is mounted on the cap by a pair of torsion hinges. The axis of the hinges is positioned directly above the valve stem such that axis of rotation of the actuator intersects the axis of the valve stem. Upon depressing the rear of the actuator, the actuator rotates about the hinge axis. Consequently, an engagement surface contacts and displaces the valve stem and, thereby, actuates the valve. A product flue is positioned at the front of the actuator which flue is rotated with the actuator such that, on actuating the valve, the product stream from the valve stem proceeds through the flue.

Abstract: A weft knitted double-jersey fabric is knitted in a construction of repeating groups of courses in which some courses have loops pulled to both fabric faces and some courses have loops pulled to one fabric face and are transversed by yarn regions which extend across at least two wales and up to seven or more wales. The yarn feed to the needle beds of the knitting machine is limited to no more than 4.0 cm/cm of bed length over which the fabric is knitted in courses in which loops are pulled to both faces of the fabric and to no more than 2.0 cm/cm of bed length, preferable no more than 1.8 cm/cm, in courses in which loops are pulled to one face of the fabric. The fabric has an extensibility of no more than 12% in wale and course directions. It is knitted with a high count yarn of 550 to 850 decitex which may be an air-textured polyester yarn. It is suitable for use as upholstery fabric particularly in the form of a vehicle seat upholstery cover which may be shaped to fit the seat in the knitting process.

Abstract: An apparatus for brushing an entire arch of teeth at once has a resilient U-shaped housing containing a channel within which the arch of teeth fits. A plurality of bristles substantially covers the surface area of the channel, and a handle extends from each arm of the housing. The channel is shaped whereby the bristles on the edges of the channel are angled into the gingival sulcus. In operation, the user grasps a handle in each hand and moves the handles in opposition to each other to move the resilient housing. This causes the bristles to move, thereby brushing the teeth in an effective manner.

Abstract: Arrays of electrostatic elements arranged in columns and rows are used for switching purposes and for memory devices. Electrostatically attracted members, for each element, when actuated, complete a capacitance device to render that element capable of retaining a charge. Whether or not the element is a capacitance device is sensed by a high frequency signal. Permanent memories can be made by substitution of a pattern of conductor areas for the attractable members. The attractable members, when attracted, form a capacitance switching device or matrix of switches.
