The combination of a body surfboard (10) and a pair of floats (20) and (21) attached together by fasteners (30), (31) and (32) passing through holes (35), (42) and (44) in the float members and similar holes in the board. A reinforcing web (50) bonded to the outer surface of a portion of each float and a reinforcing rod (52) inserted into a hole drilled from the end of each float serve to reinforce each float against breakage while allowing limited bending of the rear extension (27).

A disposable diaper containing an integral removable bag that provides sanitary storage conditions for the absorbent layer prior to the diaper's use and provides refuge for the soiled diaper by use of a foldover flap that is sealed with a fastening strip.

Disclosed is an added damping and stiffness structural element for use in optimizing the design of buildings and structures subjected to earthquake, wind or other forces that induce vibratory oscillations in buildings or structures. The added damping and stiffness element comprises conventional structural engineering materials having high shear, tension and compression moduli for transferring force from one point in a structure to another point that experience relative displacement during vibrat...

A method of on-line reconfiguring a data processing system for an added input/output (I/O) device. A configuration program is called and menus are presented. Based on menu selections, the program causes a device definition to be built. The built definition is used to construct a control block which is written into main storage during system operation such that the added device is available for use on a real time basis.

A transducer for measuring vibrations is formed of a case with a vibratory element mounted therein by means of a disk spring which is constrained to vibrate with the vibratory element in a single direction. Optical or magnetic sensors are located in registration with opposed ends of the vibratory element to produce optically or magnetically induced signals having a modulation thereon resulting from vibration of the vibratory element. The use of pairs of the sensors improves signal-to-noise ratio...

A system for monitoring and controlling the addition of water to dry concrete mix. The water is added through a solenoid-controlled supply valve to a truck-mounted mixing container rotatable by a three-phase AC motor. The power consumption of the motor, which decreases as water is added to the mix, is monitored by a load sensor transducer which produces a related DC control signal. A voltage comparator and latching circuit are provided to deenergize the solenoid and stop water flow when the DC c...

The present invention provides an insert (1) forming an independent assembly of a coil body (15). The electroacoustic transducer comprises an insert (1) formed of a case with a vibrating membrane (2) and its electric connectors (4, 5) and a coil body (15) distinct and separable from the insert. The coil body can be fitted to the rear face (14) of the insert and comprises axial passages (20, 21) through which the insert connectors (4, 5) pass. Contact pieces (22, 23) provide the electric connecti...

A device to be worn beneath footwear or an unshoed foot for increasing stride and reducing fatigue while providing comfort and stability by absorbing the energy in a stride and by releasing that energy to user. The invention accomplishes this by providing a cantilevered leaf spring joined to but separated from a platform supporting the user. As the user enters a stride weight of the user flexes the spring to store the energy of contact with terrain. Then during the completion of the stride the s...

A composition comprising no-carrier-added 1-(B-D-arabinofuranosyl)-5-(E)-(2-halogenovinyl)uracil wherein the halogen is radioactive iodine or bromine. This composition can be used to diagnose or treat herpes viral infections.

A circuit board includes two planes. A via spans the planes, and an impedance component is placed in the via. The impedance component is coupled to both of the planes. The impedance component provides an impedance between the planes without the use of traces or hand soldering of components.
