  • Hydraulic Controlled Fan Clutch With Integral Cooling
    Publication number: 20070215431
    Abstract: A hydraulically controlled fan drive system (12) having a method of engagement includes a housing assembly (20) containing a hydraulic fluid (48) and an engaging circuit (36). The engaging circuit (36) includes a pitot tube (152) coupled within the housing assembly (20) that receives at least a portion of the hydraulic fluid (48). An engaging circuit (36) engages the housing assembly (20) to a fan shaft (44) in response to supply of the hydraulic fluid (48) from the pitot tube (152).

  • Fan drive having pressure control (fluid) of a wet friction fan drive
    Patent number: 7249664
    Abstract: A hydraulically controlled fan drive system (12) having a method of engagement includes a housing assembly (20) containing a hydraulic fluid (48) and an engaging circuit (36). The engaging circuit (36) includes a pitot tube (152) coupled within the housing assembly (20) that receives at least a portion of the hydraulic fluid (48). An engaging circuit (36) engages the housing assembly (20) to a fan shaft (44) in response to supply of the hydraulic fluid (48) from the pitot tube (152). An electrical control circuit (40) having a relief valve assembly (225) coupled to a main controller (176) is used to control the fluid pressure within the pitot tube (152) that controls the engagement of the housing assembly (20).

  • HYDRAULIC FAN DRIVE SYSTEM EMPLOYING BINARY CONTROL STRATEGY
    Publication number: 20050047567
    Abstract: A method for communicating information to a caller on a telephone network is herein proposed. The method includes the steps of (a) generating a signal suitable for producing an audible dial tone, (b) transmitting the signal to the receiver of a telephone set, when the caller initially takes the receiver off-hook, to thereby produce the audible dial tone, and (c) superimposing an audible information message over the audible dial tone while the audible dial tone is produced. The audible information message may, for example, be a branding-type message that identifies a provider of local telephone service to a caller. The audible information message may be superimposed over the audible dial tone in a whisper-like or low-decibel manner to avoid interfering with modems that operate on a “wait for dial tone” (WFDT) basis.
