A protection device for a boat having a rigid hull with a waterline, gunwale and a cockpit is provided. The device consists of a first inflatable bumper mounted to the rigid hull about the gunwale, which will absorb impacts to the hull when the boat is pulled next to a dock or the like. A second inflatable bumper is mounted to the rigid hull at the waterline to keep the rigid hull afloat if it becomes cracked. A mechanism is in the cockpit, for selectively inflating the first inflatable bumper a...

A protective arrangement comprising one or several plane structures such as protective plates or elements, each one of which is meant to be used with one or several similar ones and are removably attached to one another. The structural part is stiffened in proportion to bending and has stiffening ribs. The arrangement is meant for temporarily protecting a field of grass and/or ice. One or several plastic based thermal insulation assemblies are attached to the downward side of the supporting stru...

A pillow for protecting a hairdo is disclosed. The pillow is made of foam or the like and has a hole in the center in which the hairdo can be received while the person's cheek rests on the area around the hole. The foam is sealed together around the outside periphery of the pillow and the outside periphery of the hole. A pillow case is provided having a conforming hole in it.

A file protection circuit for disc storage control units prevents unauthorized users from obtaining information from a bulk disc storage unit. Each transfer from the sequentially addressable buffer within the storage control unit is monitored so as to determine whether the data sought from the sequentially addressable buffer is from a protected field. Upon determining that the data is from a protected field, the data transfer from the sequentially addressable buffer to the main memory of the dat...

Structure for providing a file protect function for a cartridge which houses a magnetic recording medium includes a sleeve molded integrally with the cartridge. The sleeve has diametrically opposed slots and a rotary file protect actuator disposed in the sleeve has diametrically opposed projections which engage the sleeve slots to hold the actuator in position. The actuator may be rotated 180.degree. by a screwdriver or other tool, and this rotation controls the enabling or disabling of the circ...

A drum memory system is described including the circuits and their system oriented relationship necessary to reduce the probability of destroying the data stored on a rotating magnetic drum due to common faults within the memory logic and linear write-read system. The problems associated with power supply failures, the most common faults, are treated.

An apparatus for predicting the remaining useful life of a motor uses the temperature and past history of the motor to determine the amount of insulation degradation for its prediction. The remaining useful life projection is provided at a display and may be used to trip the circuit breakers supplying power to the motor when projected life is shorter than the expected life or may be used to issue a warning that the rate of motor degradation exceeds the rate necessary to achieve the expected life...

The breath protector is adapted to be worn by trotters and pacers and includes a self-supporting cover and a means for mounting the cover between a position over the muzzle of a horse and a position spaced from the muzzle of the horse. A release means for releasing the cover from about the muzzle is actuated by the driver via a cable which extends over the head of the horse. A suitable locking means is provided under the horse's head to secure the cover in the retracted position.

A write protect switch device accommodated in a disk drive comprises an arm whose one end is supported by a frame of the disk drive, and a rotatable cam member supported by the other end of the arm, whose abutting end slides on a casing of a disk cartridge, the cam member displacing the other end of the arm in the direction of separating from the frame at the time of insertion of the disk cartridge; fitting into a write protect notch of the casing to displace the arm in the direction of approach...

A write-protect clip can be permanently installed on a floppy disc and thereafter can be moved to an opened position which exposes the write-protect notch of the floppy disc or to a closed position which covers the notch. The clip, which is a unitary element made from a sheet of metal, includes first and second walls which slidably engage the outer surface of the envelope of the floppy disc, a back wall which connects the first and second walls, and a serpentine spring tongue which extends betwe...
