A braking servomotor (10) having a rigid casing (12) with a movable wall (14) location therein to define a front chamber (16) and a rear chamber (18). The movable wall (14) carries a piston (22) that slidably receives an actuating rod (28) for a master cylinder (36). A control rod (28) is sliding located in a bore inside a piston (22) and moved as a function of an input force. The control rod (28) has an end that bears against a plunger (46) that has a finger (52) that biases a reaction disk (32...

A toothbrush having a handle formed of a thermoplastic material with a glass transition temperature in the range of about 110.degree.-140.degree. F. The handle is heated to soften the plastic shaped to a desired configuration while pliable, then allowed to cool so as to retain the desired configuration when it hardens. The brush bristles may be detached from the handle when worn and replaced by a fresh set.

A plastically deformable stent for implantation within a body passage includes a plurality of cylindrical segments, and a plurality of connectors extending between adjacent segments. Each segment has an alternating pattern of curvilinear elements extending about its circumference, including first and second sets of curvilinear elements having different resistances to expansion, and preferably defining "U" shapes with alternating lengths that are connected to one another to define a substantially...

A closure of synthetic resin material has a cap connected to a base which fits onto the container by a hinge joint which may be of the flexible film type and can be molded unitarily with the base and cap. On the opposite side of the cap from the hinge, there is provided a lever which has a pressing plate and a hook, the latter being engageable with a detent on the base so that entered pressure on the plate allows the cap to swing upwardly.

In a deformable system whereby electrical energy distribution conduits and conductors disposed longitudinally therein can be connected along a curved path, the system comprises a deformable central part containing a layer of conductors. Said central part comprises links hinged about axes parallel to the layer and perpendicular to the conductors, which latter are plastically deformable. They are solid conductors having a section which is flattened in the transverse direction of the layer of condu...

Devices for vehicles or the like to reduce shock of collision by utilizing energy absorbing material which compresses under the force of impact of collision offering increased resistance and effecting gradual momentum deceleration of the moving vehicle as it is being compressed.

A valve assembly comprises a relatively rigid member defining a fluid flow port and a movable member adapted to engage the port with a fluidtight fit. One of the members is formed with an annular recess in which is mounted a resilient seal ring adapted to engage and be compressed against the rigid member to provide a sealing closure. This seal ring has its opposite sides sealed and maintained immovable as by suitable bonding or clamping to the opposite sides of the recess. A space is provided in...

An assembly which includes a frame and an air-guiding panel such as a louver. The frame has a pair of panel-carrying vertical ribs respectively formed with notches while the panel has opposed edge portions of a cross section matching that of the notches and received therein. Each of the ribs of the frame is provided next to its notch with a deformable locking nib while the edge portion of the panel adjacent to the locking nib is formed with a locking cutout. According to the method of the invent...

A hose fitting wherein the free end of a nipple or pipe is sealingly held in one end portion of a hose by a sleeve having a tubular body with a single axially parallel slot and one or more bridges extending across the slot at the exterior of the tubular body. The latter has depressions which extend toward the nipple or pipe to urge the end portion of the hose into sealing engagement with the nipple or pipe. The sleeve can be detached from the end portion of the hose by partially or fully destroy...

A plastic surgical clip comprises a pair of arms having inturned opposing tips, the arms being joined by a bridge having a lesser cross-section to provide a locus for bending by drawing the ears in parallel directions against an intermediate support.
