Abstract: Disclosed herein is a method of distributing a washcoat along channels of a particulate filter substrate, the method including: forcing a washcoat slurry a predetermined distance into the channels, the predetermined distance being less than or equal to the full length of the channels; clearing an excess amount of washcoat slurry from the channels; and arranging a remainder of the washcoat slurry within the channels, the arranging including applying a first vacuum to a first end of the particulate filter substrate after the clearing. In one embodiment the clearing includes applying a second vacuum to a second end of the particulate filter substrate. In another embodiment, the clearing includes pulling the excess washcoat slurry from the channels. The predetermined distance may be less than or equal to the full length of the channels.
Abstract: Certain circuit faults in a phase of a multi-pole, switched reluctance, rotary electrical machine are detected; and the machine is selectively operated with a detected circuit fault when the nature of the fault permits continued operation of the phase and the operation of the phase is desirable. The fault may be one of certain short or open circuits in which at least one of the two current controlling electronic switches is operable to control phase current within predetermined limits. In the continued operation when a fault is detected, (1) the phase current is switched off earlier than it would be in the absence of the fault and/or (2) the maximum phase current is reduced compared with that permitted in the absence of the fault; and either or both of these modifications may be a function of motor speed. If the circuit fault adversely affects current control by an electronic switch normally controlling current level, another electronic switch is substituted for current control.

Abstract: A blowoff valve assembly includes a diaphragm separating a refrigerant connection from an ambient port open to the atmosphere. The refrigerant connection is preferably connected to air conditioning system such that the diaphragm is in contact with refrigerant from the system. The diaphragm is deflectable based on the pressure of the refrigerant and is operatively connected to a switch. When pressure of the refrigerant drops to a predetermined level, the diaphragm deflects to activate the switch. Additionally, the assembly also includes a detonable squib that explodes and ruptures the diaphragm, allowing the refrigerant to flow from the refrigerant connection to the atmosphere. Additional features, such as sensors for detecting refrigerant outside of the system, a collision subsystem, and an associated controller are also disclosed.

Abstract: A system optimizes terrestrial signal acquisition in a communication system by initially determining whether a first synchronization signal is available from a first ensemble, which has an associated first programmed content of a terrestrial signal. Next, when the first synchronization signal is not available from the first ensemble, the system switches to a second ensemble of the terrestrial signal to acquire a second synchronization signal, which is synchronized with the first synchronization signal. Finally, the system switches back to the first ensemble to retrieve the associated first programmed content.

Abstract: An improved pin housing sub-assembly configured for reliable assembly and stability as an intermediate sub-assembly. The length of the plunger return spring is greater than the diameter of the spring well in the pin housing, such that the spring cannot be accidentally installed sideways in the well. During assembly, the non-compressed longer spring places the pushrod seat flush with the end of the pin housing. A shallow annular groove is provided in the inner wall of the pin housing near the outer end thereof, and an expansion ring may be installed therein when the plunger return spring is slightly compressed. The expansion ring holds the sub-assembly together as an intermediate but is displaced by the spring tower in a subsequent assembly step to become the locking ring between the pin housing and the spring tower, as in the prior art.
