An aircraft wing includes a stationary root section and a telescoping end section slideable in the span wise direction, where the loads for the root and extendable end sections are carried predominately by the airfoil composite skins, rather than a framework of spars and ribs as in conventional aircraft wings. In a single-telescoping configuration the telescoping end section slides within the root section as it extends and retracts during flight, and in another, the telescoping end section slides over the root section as it extends and retracts during flight. The aircraft wing can also include a second telescoping distal end section, and can sweep back during flight, while the end sections or distal end sections are extended or retracted.

A device for producing waves and body in hair comprising curling tongs having heatable leg elements. The heatable leg elements have a wave shape with decreasing amplitude. The amplitude decreases from a maximum at the scalp-contacting end of the heatable leg elements to substantially no amplitude at the other end of the heatable leg elements. Heat-reducing lips may extend from the scalp-contacting end of the device. In one embodiment, the heatable leg elements are arcuate and can pivot about an axis extending along each leg, respectively. A method of using the device to form waves and body in hair wherein the amplitude of the wave is greatest near the scalp and decreases along the length of the hair in the direction toward its tip.

The lift is attachable to a foot end of a bed beneath a mattress. Elongate arms extend up from a base portion of the lift. Sheets or other bed covers are supported above an upper end of the elongate arms to define a clearance space beneath the upper ends of the elongate arms. The elongate arms are preferably provided as a pair of first arms and a pair of second arms which can be moved from a lowered position to a raised position by action of a driver. When the arms are raised the clearance space keeps the bed covers off of feet of a user resting on the bed.

The rotary gas tap (1) with an electromagnetic safety valve (3), is of the conical regulation member (7) type, and the electromagnetic actuator (3a), being of a smaller power and size, is built entirely into a pipe housing (2a) in the body of the tap. The valve actuator (3a) is of the type where the seal member (9) is lifted by means of a DC voltage. The cylindrical magnetic frame (14) penetrating into the coil (15) is guided inside it, and a magnetic capsule (16) surrounding the coil is of a diameter Dh of around 14 mm, adjusted to that of the housing (8) in the body of the tap (2a). The stroke “R” of the seal member (9) corresponds to a gap (G) greater than 2.5 mm, reaching a sizeable passage opening “A” in the valve (9,10) necessary for a maximum inlet flow (Q) in the tap. At the same time the electromagnetic actuator (3a) is of low power, by means of a low reluctance in the magnetic circuit (13-16), although the diameter “Da” of the cylindrical frame is restricted to less than 4 mm.

An adjustable-length compression spring comprises a casing filled with pressure fluid. A piston rod is sealingly extended through a guide and seal unit which closes the casing, a piston, which is sealingly guided therein, being joined to the piston rod. The piston divides the casing into two sectional casing chambers, which are filled with pressure fluid. For connection to each other of the sectional casing chambers, provision is made for a valve operated by a valve pin. The casing includes a locking mechanism which comprises a first and a second locking element, the first of which being in pushing connection with a first operating element and the second with the valve pin. They cooperate in the way of a retractable-ballpoint-pen mechanism so that, in a first position of locking, the valve pin takes a position of release with free connection between the sectional casing chambers and, in a second position of locking, it takes a position of blocking with any connection between the sectional casing chambers being shut off. This type of integrated locking mechanism can be made solid, nevertheless needing little space.
