Abstract: A clamp pressure controller for a variable ratio belt drive system for a generator is provided. The controller monitors the voltage at the output of the generator. If this falls the controller increases the clamp pressure so as to prepare the drive system for the additional torque/force it will be required to transmit. The increase in clamp pressure is rapid so as to prevent belt slip from occurring.

Abstract: A belt clamp force regulator is provided for controlling the clamp force exerted on a drive belt in a continuously variable transmission. The regulator seeks to maintain a clamp force greater than that required to transmit the mechanical load consistent with the output of the generator. This ensures that the belt will not slip. However, the controller reduces belt clamp when it can so as to improve the service life of the belt.

Abstract: Gas rarefaction, and loss of ionization efficiency, resulting from magnetron sputtering in IPVD may be avoided by operating the magnetron in a pulsed fashion, rather than in a steady state, during the deposition process. The magnetron is powered during a first time period to produce a flux of atoms which heat the gas, and depowered during a second time period. The gas flows through the device during the powering step and the depowering step so as to prevent rarefaction of the gas by heating. The flow of gas through the device is characterized by a residence time. If the residence time is given as &tgr;, and the first time period and the second time period are substantially equal, the operation of the magnetron may be characterized by a frequency of 1/&tgr;. The second time period may be greater than the first time period.

Abstract: A deaerator is provided in which the oil to be deaerated is supplied to first and second chambers and, respectively, arranged in a side by side manner. The oil is introduced tangentially so that a rotary motion is introduced therein. The rotary motion causes the oil and air entrained therein to separate out due to centrifugal/centripetal forces. Air is removed via a centrally disposed tube.

Abstract: A removable grease dam tool to facilitate proper filling of grease within a wheel hub assembly and a method of using the same. A grease dam is placed adjacent an outer surface of a wheel hub mounted to a spindle. The grease dam blocks at least 50% of the exposed area between the wheel hub and spindle and leaves a top portion open to allow greased to be injected into the inner cavity of the wheel hub. A portion of the grease dam is disposed within the wheel hub between the wheel hub and spindle to simulate the presence of the outer bearing. Once the inner cavity of the wheel hub is filled beyond a 50% fill level, the grease dam is removed and the outer bearing assembly is immediately thereafter installed. The tool prevents leakage of grease during assembly to ensure at least a 50% fill level. A handle is provided to facilitate manipulation by a user.

Abstract: The application describes the addition of serrations to the edge of the light transmissive layer of an integrated optical device. This enables scattered background light to be coupled out of the device, improving the signal-to-noise ratio.

One or both of the first and second legs includes a plurality of preformed patterned holes having sizes that can receive fasteners. A roofing structure is fabricated using the roofing brackets.

Abstract: Benzotriazole UV absorbers substituted with an ultra long ester or amide moiety wherein the ester or amide group is a hydrocarbyl group of 25 to 100 carbon atoms or is a group of alkyl of 25 to 100 carbon atoms interrupted by 5 to 39 oxygen atoms and terminated with an omega—OH or an omega—OR group exhibit excellent stabilization efficacy while they concomitantly do not bloom when incorporated into polyolefin films. These benzotriazole UV absorbers also provide excellent protection to white, dyed, dipped, unscented and/or scented candle wax from discoloration and degradation.

Abstract: Roofing structure includes roofing brackets having a first leg attached to vertical members of a roof structure and a second leg that extends at an angle from the first leg and attached to horizontal members of the roof structure. Brackets serve to attache the vertical members to a support surface of the roof. The first and second legs include a plurality of preformed patterned holes and slots having varying sizes to receive fasteners. The pattern and size of the holes and slots allows for fastening of the brackets to steel bar joists while enabling the fasteners in the slots to be fastened near center lines of the respective bar joists. The slot sizes and positions enable fastening to steel bar joists for most distances between the flanges of their top angle chord members.

Abstract: A cooling structure and a reinforcing structure are described for use with a radio-frequency coil in an ionized physical vapor deposition apparatus. The cooling structure includes a portion for carrying coolant and is proximate to the RF coil along the outer circumference thereof. The cooling structure is shaped relative to the RF coil so that thermal expansion of the RF coil brings the RF coil into close contact with the cooling structure, thereby facilitating heat transfer from the RF coil to the coolant. The reinforcing structure is similarly shaped, and may be integrated with the cooling structure. In addition, the RF coil or cooling/reinforcing structure may be mounted to the wall of the process chamber with telescoping mounting posts, which permit the RF coil to maintain its shape while undergoing thermal expansion. The parasitic inductance of the RF coil leads is reduced by arranging those leads coaxially, thereby minimizing power losses in the RF coil.

Abstract: Improvements are described for a wafer clamp ring used in an IPVD apparatus to provide cooling for the wafer clamp ring, to protect the wafer clamp ring from ion bombardment, and to prevent damage to the wafer. The wafer clamp ring is placed on a cooling fixture when not required for a deposition process. The fixture is annular in shape and in close thermal contact with a circulating coolant and is thereby cooled below ambient temperature. The cooling line and the cooling fixture are fixed relative to the IPVD device, so that problems associated with flexible cooling lines are avoided. An annular grounded shield may be provided between the plasma and clamp ring to protect the clamp ring against ion bombardment during the deposition process. The wafer clamp ring may have a portion which overhangs the wafer during a deposition process, and which has a ridge portion extending downwards therefrom and tapering to a knife edge.
