Abstract:
A method for preparing and applying a thermoplastic resin base coating to the surfaces of a seal assembly for a rotary regenerator in a gas turbine engine, the coating comprising a high-temperature, thermoplastic resin filled with a lubricating material, said method including preparation of a bond coating on the surface of a seal assembly shoe portion, preparation of coating material having a percentage of graphite and a percentage of boron nitride, dissolving the coating material in a suitable solvent to form a paste which may be applied to a seal shoe portion of the seal assembly used with the ceramic rotary regenerator matrix, curing the coating material and finish grinding the seal assembly following curing whereby the seal assembly is conditioned for operation with reduced friction and improved sealing characteristics at the elevated temperatures that are characteristic of gas turbine regenerator installations.
Abstract:
A window regulator mechanism for raising and lowering adjacent movable sections of a divided window panel. The window mechanism comprises an elongated mounting plate having a pair of gear sectors rotatably superposed on a common pivot shaft journalled in the mounting plate intermediate the ends of the latter. Each gear sector has a regulator arm fixed thereto adapted to be coupled to one of the window panel sections. Independent reduction gear units are located at opposite ends of the mounting plate, each coupled to a respective gear sector. A cable drive means couples each reduction gear unit to an electric drive motor, each drive motor being independently operable to rotate the gear sectors to swing the regulator arms in window panel section lowering or raising direction.
Abstract:
Apparatus is disclosed for communicating a plurality of fluidized sources with a spray apparatus. A plurality of sources are communicated to individual ones of a plurality of ports extending through a stationary plate member. A rotary and longitudinally displaceable plate member is arranged in alignment with the stationary plate member and is provided with a single orifice which communicates with the spray apparatus. The rotary plate is further provided with means forming a sealing member which are arranged to cooperate with gasket means provided for each of the source orifices on the stationary plate member so as to sealingly close the nonselected orifices and to provide for contamination free communication between the selected source orifice and the single orifice on the rotary plate member.
Abstract:
A catalyst converter of the type employing a radial flow catalyst substrate. First and second enclosing can sections define an interior volume sufficiently large to have the radial flow catalyst substrate supported therewithin. Structure is provided for blocking one end of the radial flow catalyst substrate and additional structure is provided for mounting the blocking structure in contact with one end of the catalyst substrate. Support and sealing structures are provided at opposite ends of the enclosed catalyst substrate in order to resiliently cushion the substrate. The structure permits exhaust gases to flow into the interior volume of the catalyst substrate, radially through the substrate and then out to an exhaust pipe. The substrate has catalytically active material thereon for eliminating undesirable components of the gas stream passing through the converter.
Abstract:
A circuit for controlling a seatbelt retractor of a motor vehicle. The retractor is of the type which permits initial withdrawal of the seatbelt from the retractor and which locks to prevent further seatbelt withdrawal upon decrease of the withdrawal force or upon slight retraction of the seatbelt. The control circuit prevents the locking of the seatbelt retractor if the vehicle is in a predetermined condition, such as its transmission lever being in a neutral or park position, and if the vehicle seating position for which the seatbelt retractor is provided is occupied. Prevention of retractor locking simplifies and eliminates annoyance to a vehicle occupant fastening the seatbelt about him.
Abstract:
An electroplating system for cathodically plating an epitrochoidally shaped internal surface of a rotary engine housing. An anode assembly is provided which is comprised of a perforate walled container of titanium metal or other anodically inert metal to which a voltage potential can be applied; the basket contains anode pieces such as nickel which are shaped to be in intimate contact with each other during the plating operation. The perforate walls of the anode container is shaped from flexible expanded titanium sheet metal interfitted within semi-epitrochoidally aligned grooves respectively machined into titanium plates forming the ends of the anode assembly. The anode walls are thus shaped substantially complimentary to the epitrochoid configuration of the cathode but have a predetermined deviation adjacent the nodes of the trochoid for insuring a uniform but heavy coating thickness under high speed electroplating conditions.
Abstract:
A bridge circuit is disclosed for combination with a variable resistance sensor whose resistance may vary as a function of a sensed variable and also as a function of a parasitic variable such as, for example, temperature. The bridge circuit includes at least one variable resistance which varies as a function of the parasitic parameter and is relatively insensitive to the sensed parameter. The bridge circuit comprises a first leg incorporating the sensor resistor having a tap junction whose voltage varies as a function of the sensed parameter and of the parasitic parameter, a second leg including the parasitic parameter responsive resistance and having a voltage tap whose voltage varies only as a function of the parasitic parameter and a third leg interconnecting the first and second leg voltage taps and having a signal tap whose voltage varies only as a function of the sensed parameter. In a preferred embodiment, a resistance type exhaust gas sensor whose resistance varies as a function of the partial pressure of oxygen in the exhaust system of an internal combustion engine and also as a function of the temperature of the environment of the exhaust system is compensated by the circuit of the present invention to remove temperature dependency effects.
Abstract:
The present disclosure relates to an independent rear suspension system for a motor vehicle having front wheel drive. Left and right road wheels are rotatably supported by left and right wheel support members. The wheel support members are positioned relative to a vehicle body by means of a transverse single leaf spring that is secured by a pair of clamps to the body and by pivots to the wheel support members. Vertically extending telescopic shock absorbers are rigidly secured at their lower ends to the wheel support members and pivotally connected to vehicle body structure at their upper ends. The wheels are nonsteerable and are nondriving. The leaf spring and shock absorbers determine the vertical jounce and rebound path of the wheels. They also provide the sole means for transmitting brake torque reaction to the vehicle body.
Abstract:
A clutch release mechanism having a support member with a radial flange. A self-centering clutch release bearing is disposed on one side of the flange and a clutch release lever is disposed on the other side of the flange. A pair of loop springs holds the lever and the bearing in engagement with the flange.
Abstract:
A rotary internal combustion engine of the Wankel type is disclosed. The engine has at least one epitrochoid chamber with flat side walls and an associated triangulated rotor cooperatively defining a plurality of variable volume chambers. An oil metering apparatus is integrated into the rotor for directing a jet or reservoir of oil, preferably fed from a high pressure supply, against the side walls of the housing. The apparatus employs a biased plunger to distribute a controlled oil film about the housing side walls in cooperation with the eccentric path of the selected plunger location, preferably remote and independent from the dynamic seal grid system. The oil film is pumped by action of arcuate or annular side seal strips to migrate and coat intermetallic contact surfaces of the variable volume chambers. Oil consumption is reduced while providing a functional film at predetermined locations.
