Abstract: Rechargeable battery packs for table lighting each contain a 3-element phono jack in their base for engaging a battery recharger phono plug the insertion of which opens the lamp circuit. If a phono plug has short circuited elements, its insertion into a battery pack causes a short circuit of the battery resulting in damage or destruction of the pack. This is prevented by inserting a diode in the circuit to permit current flow in one direction. Also disclosed is a fault locator for locating a shorted plug of many plugs on a charger board.

Abstract: A truck tire/wheel assembly detection system in which the moving thermal dynamics of a truck are measured before cooling off, by passing over and around contact or non-contact thermometers directed toward the tire/wheel assembly and transmits the approximate temperature of each tire/wheel assembly to a computer which will compares the output data and identifies each abnormally overheated tire/wheel assembly and print out location on rig and other information that may be required. A modem controlled by the computer is used to advise other interested parties of rig condition at this check out point.

Abstract: A protocol for fiber-optic communication systems, or other communication systems based on transmission of unipolar pulses having wide dynamic range provides for information to be transmitted in packets having a predictable time slot for each transmitter. The receiver for such protocol has a first relatively long RC time constant mode conditioned for reception of data packets whose time of arrival is well predictable and a second relatively short RC time constant mode conditioned for reception of asynchronous randomly received packets. In the relatively long RC time constant mode, each packet includes a preamble having a first clamp interval in which no pulse is transmitted, and a second clamp interval in which a continual pulse is transmitted. A transducer on the receiver translates the packets of pulses into differential electronic signals on first and second outputs.

Abstract: A dip coat process material handling system and method for coating multiple layers of material on a plurality of workpieces, in particular for producing a multi-layer optical photoconductive drum, wherein a plurality of pipes are suspended from a carrier pallet which transports the workpieces through a dip coat cell housing various dip coating stations. The system includes a load/unload station, vertical and horizontal transport systems for transporting the carrier pallet having workpieces loaded thereon to the various dip coating stations, a drying/cooling booth, and a return conveyor system. The invention allows complete dip coat processing to be completed in an in-line configuration while the workpieces are attached to the carrier pallet, thereby eliminating load/unload steps at each dip coating station to provide efficient and flexible processing of materials.

Abstract: An endless metal belt resistant to failure due to stress induced by bending contains an internal stress gradient of radially outward increasing compressive stress which opposes external stress applied to the belt. The belt can be made by an electroforming process. While electroforming, at least one operating parameter selected from bath temperature, current density, agitation, and stress reducer concentration is adjusted to cause the internal stress to gradually increase, compressively, from the radially inner surface of the belt to the radially outer surface of the belt. The internal stress preferably increases at a substantially constant rate and may range from about 160,000 psi tensile at the inner surface to about 120,000 psi compressive at the outer surface.

Abstract: An electroforming process for forming a multilayer endless metal belt includes forming increasingly compressively stressed successive layers on a mandrel, and assembling the layers to form a multilayer belt. The belt is particularly useful as a driving member for a continuously-variable transmission.

Abstract: Ductility of belt material is increased at least at one edge of an endless metal belt, thus reducing the likelihood of premature failure of the belt. The inner region of the belt maintains the inherent strength of the metal. The endless metal belt so formed is particularly useful as a driving member for a continuously-variable transmission.

Abstract: A digital phase acquisition circuit includes circuits for detecting an edge of incoming data and a plurality of candidate clock phases, the circuitry further including logic for determining when the data undergoes a predetermined phase transition and at least one candidate phase which undergoes a digitally equivalent transition close in time to the data transition so as to enable the candidate phase to be used for choosing an appropriate clock phase for recovering information representative of the data. The circuit further includes logic for comparing a frequency of the chosen clock pulse and the data and adjusting at least one of these frequencies when a predetermined amount of drift therebetween is detected. The invention allows clock to be recovered within 1 bit time of a predetermined data transition occurring and allows an appropriate clock to be maintained through an entire packet regardless of packet length.

Abstract: An imitation candle type of table lighting fixture contains one or more rechargeable batteries. While the lamp is in its holder, the battery is continously coupled to the small light bulb. The battery is recharged by removing the candle from the holder and plugging it into a recharging unit having a phone plug extending into a jack centered in the bottom of the candle. The insertion of the plug into the jack opens the light bulb circuit and forms a charging circuit through the rechargeable battery.

Abstract: A wheel mounted hub containing an electrical generator which is pivotally supported in arms of a yoke. The yoke and generator have an offset center of gravity, tending to give the yoke and generator a pendulum-like behavior within the housing. During wheel rotation, the generator tends to remain along a gravitational line of force, forcing a small wheel associated with the generator to turn against the hub. Around the outer periphery of the yoke, yet within the hub housing, is a circuit board which carries a power utilization circuit, so that the electrical path between the generator and the utilization circuit is very short. The circuit board may carry auxiliary circuits such as a current limiter, a generator disengaging circuit, a daylight deactivating circuit and a circuit for allowing operation regardless of direction of rotation.

Abstract: A shroud for a gas turbine engine rotor stage is divided into a number of arcuate segments each of which is a trapezium. The segments are urged together by compression springs which attempts to make the assembly lengthen peripherally, by virtue of the chamfered ends 30 of the segments riding up each other. The completely circular shape of the shroud prevents that movement but as a result, a hoop load is generated which tends to move the segments radially outwards, thus achieving the same effect, along with a consequent increase in diameter. A cam ring and pins are used to control and reverse the movement, as desired. The shroud diameter can thus be altered to suit rotor expansion and contraction.

Abstract: A generator assembly characterized by a pair of plates driven in opposite directions, and a pair of generators each engaged with one of the rotating plates. The generators are attached to a generator support bearing supported by a central shaft that is rigidly attached to a first plate and which is rotatably coupled to a second plate. A third plate and a drive gear are used to rotate the second plate in a direction opposite to that of the first plate.

Abstract: A generator assembly characterized by a hubcap and an elongated arm attached at a first end to a central portion of the hubcap such that it may freely rotate therein. A generator is attached to the second end of the arm which is operative to produce electrical power as the hubcap rotates. Because of the generator's offset position there is a "step-up" effect of the mechanical power supplied to the generator, thus increasing the electrical power developed by the generator. The elongated arm can also be attached to the wheel lugs of the wheel by a suitable frame, or may be manufactured as an integral part of a wheel or hubcap.
