  • Patent number: 5556679
    Abstract: A dual pipe installation comprising a sump including a wall having inner and outer surfaces, and an opening extending there between, a pipe assembly extending into the sump and comprising an outer flexible pipe extending lengthwise and being defined by an endless wall which includes a plurality of corrugations in serially adjacent lengthwise relation, and a lengthwise inwardly open channel, and an inner flexible pipe which extends within the outer pipe, which is defined by an endless wall defining an interior and including a plurality of corrugations in serially adjacent lengthwise relation, and a projecting end portion extending axially outwardly beyond the end of the outer pipe and having an outer end, and which defines, with the outer pipe, an annular space.

  • Patent number: 4468554
    Abstract: An electric hair curling appliance includes a metallic heater tube extending fixedly from one end of a handle and containing an electric heating element. A tubular member including a hair grooming attachment removably received on an inner metal tube is telescopically mounted on the heater tube and is capable of axial and rotary motion relative thereto. A manually operable lever on the one end of the handle cooperates with first and second surfaces on the adjacent end of the tubular member to selectively (1) lock the tubular member against rotary or axial movement (2) lock the tubular member against axial movement while permitting rotary movement thereof and (3) permit axial and rotary movement of the tubular member to facilitate telescopic removal or mounting of the tubular member on the heater tube. The hair grooming attachment may be rotatably or nonrotatably mounted on the inner metal tube and may include a plurality of rows of hair grooming teeth or a pivotally mounted hair clamping member.

  • Patent number: 4439163
    Abstract: Disclosed herein is an outboard motor comprising a steerable and tiltable propulsion unit including an engine, a speed control mechanism movable from an idle speed setting to range of advanced speed settings, a starting mechanism operable to start the engine, a transmission shiftable between a neutral position and a drive position, and a mechanism connected to the transmission for preventing starting of the engine when the transmission is absent from the neutral position, and for preventing shifting of the transmission to the neutral position when the speed control mechanism is at a setting advanced from the idle setting, and for releasably holding the transmission in the neutral position, and for biasing the transmission from the neutral position and toward the drive position upon release of the transmission from the neutral position.

  • Patent number: 4403970
    Abstract: Ignition pulses derived from an engine ignition coil primary are fed to the input of an ignition interruption circuit that employs an integrated circuit timer. The state of the output terminal of the timer is governed by an RC time constant circuit and by trigger signals supplied by a trigger circuit in response to occurrence of each ignition pulse. The timer output is coupled to the gate of an SCR which when it receives gate current as a result of the timer output being in a high state becomes conductive and bypasses ignition pulses to ground to thereby lower engine rpm to a preset minimum in which case gate current is removed and at least enough ignition pulses are allowed to be unbypassed for keeping the engine running above stalling speed. The timer, in effect, compares the interval between pulses with its time constant.

  • Patent number: 4403972
    Abstract: A marine propulsion device is disclosed as including a housing surrounding an engine and including a sump which may collect water. A siphon conduit is provided for removing water from the sump, the siphon conduit including an inlet end housed in the sump and a discharge end projecting from the housing for discharging water from the sump. Another conduit is connected to the siphon conduit and for generating water flow through the siphon conduit from the sump and toward the siphon conduit discharge end, this second conduit being connected to the engine water pump and adapted to force a jet of water into the siphon conduit and toward the discharge end of the siphon conduit.

  • Patent number: RE31861
    Abstract: .[.Disclosed herein is.]. A throttle control for an engine including a housing supporting a control lever for rotation relative to a neutral position, a throttle lever movably mounted on the housing and adapted to actuate the engine throttle, a throttle drive member including a drive pin and mounted for rotation in response to movement of the control lever from the neutral position, and a cam member connected between the throttle lever and the throttle drive member. The cam member includes a cam track receiving the drive pin and having a shape effective to displace the cam member relative to the throttle drive member, transversely relative to the rotational axis of the throttle drive member, so as to move the throttle lever in response to rotation of the throttle drive member.
