A mooring device for receiving and securing mooring hooks or clamps used in ooring loads such as helicopters to a platform, such a ship's deck, subject to instability, includes an upper perforated plate adapted to receive a mooring hook without sliding, and a lower or base support structure which provides overall resistance to impact loading. A matrix of upright supporting columns join the perforated plate to the base. The portions of the upper platform defining the perforations are preferably o...

A semiconductor device wherein a beam lead connected to each wiring layer is all formed on a silicon nitride film of a semiconductor wafer surface in a semiconductor device having a multilayer wiring structure on a semiconductor basic board.

The disclosure relates to a test instrument of compact size, operable with a battery source and capable of measuring with high precision voltages in the millivolt and low voltage ranges, milliamps, provide precision outputs in the millivolt and low voltage ranges, precision milliamps outputs and provide a two wire transmitter simulation. Measurements are made utilizing light emitting diode (LED) devices and operational amplifiers operating at high levels to minimize errors.

A hair dressing device is disclosed for hair styling. This device is suitable for setting strands of hair in a curled or straight condition unlike roller devices which always set the hair in a particular size of curl. The finishing device has a flexible pad and a flexible cover with a means for securing the pad to the cover so that the strands of hair are retained therein. There are openings in the pad and the cover adapted to admit air to the strands of hair to set and dry them. There are a plu...

The essence of the present invention resides in the use of a belt which is adapted to fit around the waist of an individual and which is provided with a warning device thereon. The individual may be a swimmer, skin diver or snorkeler. The belt structure includes a mid-section being provided with a padding which is disposed on the inside surface thereof. The mid-section of the belt is provided with an upwardly extending flexible arm retaining member. A flexible arm extends upwardly from the retai...

A chipping hammer is suspended in an obliquely downward directed arm that is swingable both laterally and vertically. The feed arm includes a reversible pneumatic jack whose piston rod is rotatable with respect to its cylinder. A holder is mounted on the end of the piston rod by means of a transverse pivot joint. The holder includes a ball bearing that is mounted on the forward portion of the housing of the hammer. A device in the form of a pneumatic jack or balance block is arranged to counterv...

A unitary integrally formed hollow device having a body portion terminating at one end in a curved fork-like configuration which is contoured to fit the dimensions of an individual's mouth and with the prongs of the fork including small apertures penetrating therethrough in communication with the interior of the fork, and a watertight snap-on cap affixed to the opposite end of the body member, the device adapted to receive a liquid therein, such as water, with the liquid then being frozen after ...

A vibrator isolator designed for universal mounting between a vibrating object and a supporting structure to provide resilient support and allow relative motion between a vibrating object and the supporting structure comprises a resilient rubber member, at least one attachment means bonded to the resilient member and coiled wire bonded inside the resilient member for retaining the attachment means in its bonded relationship to the resilient member.

An electrosurgical device in which high frequency electrical energy powers a cutting electrode. Radio frequency energy is set up in a driver coil and a driven coil mounted in a handpiece. The driver coil energizes the driven coil to energize a surgical electrode connected to one end of the driven coil. Connection between the source of radio frequency energy and the driver coil includes a circuit in which condensers and impedances are so connected that, if there is a failure of the condensers, en...

An expansible self-locking fastener is disclosed for mounting in a hole of a given diameter contained in a support. The fastener includes a resilient unitary body member of a configuration defining flange, body, constricted neck and collar portions, said body member being provided with external rib means that prevent rotation thereof relative to the wall surfaces of the hole.
