  • Patent number: 5174113
    Abstract: An exhaust outlet with venturi is disclosed, comprising an upstream portion (18) in the form of a venturi, defined by upstream walls (16) converging at an open angle and connected, in a narrowed portion (15) to downstream walls (17) diverging at a more reduced angle and a cylindrical downstream portion (3) connected continuously to the downstream walls (17) of the upstream portion (18). The presence of the upstream portion in the form of a venturi substantially reduces the backlash noise without substantially affecting the available power of the engine.

  • Patent number: 4926519
    Abstract: A plastic trowel wherein strength is achieved through use of a blade with a smooth lower side and with handle-retaining members integral with an upper side. Strengthening ribs are disposed on the upper side of the blade. A ribbed handle includes end portions having broad flat areas for contacting the upper face of the blade. Openings in the end portions engage bosses defining the handle-retaining members. The bosses are upset to fasten the handle to the blade. Fastening may be supplemented by cementing or ultrasonic welding the abutting surfaces of the end portions and the blade.

  • Patent number: 4898401
    Abstract: A device for preventing backward movement of skis comprising a flap hinged on a crosswise pin carried by a lug solidly connected with the ski; two bent and counterbent lateral arms having ends, shaped like pivot pins, which are mounted in rotation in bores of said flap around a pin placed in a longitudinal plane; a lock for locking the arms above the ski in an inactive position; and a device for bringing the arms from the inactive position to an active position in which they extend laterally with respect to the ski, this device including a control rocker able to pivot between a front and a back position around a horizontal crosswise pin placed in front of the flap pin, an elastic pusher connected to the control rocker having a notched free end which, when the control rocker is brought into the back position, covers a crosswise nose projecting from the front end of the flap and causes the flap to pivot so as to raise the arms relative to a locking cradle on the ski, and a spring for separating the arms in the

  • Patent number: 4792236
    Abstract: A paint tinter system includes a plurality of canisters disposed in a circle about a rotatable plate. An orbiting plate, driven by a single motor, is connected to drive arms, each of which is connected to a crank arm of a stirrer in one of the canisters. The connection is made through a lost-motion device in a cap covering each canister. The cap captures the end of the drive arm, whereby the cap may be removed and hinged out of the way for providing access to the canister. An impeller is freely mounted for rotation in a socket in the bottom of the canister. The upper end of the impeller is driven by engagement between a pair of driver bosses rotated by the crank and edges of a top plate on the canister. Thus, when the cover is removed, the impeller may remain unmoved or be lifted from the socket for cleaning.

  • Patent number: 4485732
    Abstract: A machine for the pitting of drupaceous fruits, e.g. prunes, has an endless chain of articulated conveyor plates each provided with several vertical cylindrical bores whose flared mouths face upward on the upper run of the chain where each plate passes successively, in steps, through a loading station, a pitting station and an ejection station. The loading station comprises a hopper filling each bore of an underlying conveyor plate with a fruit to be pitted; in the pitting and ejecting stations, the conveyor plates are overhung by a vertically reciprocable carrier supporting a series of pushers and an adjoining series of plungers. In the pitting station the conveyor plates are underlain by a base plate having perforations aligned with their bores, each perforation being provided with an elastic insert which closes around a pit being dislodged by a pusher in order to strip adhering pulp therefrom.

  • Patent number: 4415270
    Abstract: A device for mixing paint and similar thick liquids within a container in which the container is held between the jaws of a clamp and rocked back and forth by a source of power. The clamp jaws are freely mounted so that they can rotate with the container about its longitudinal axis. An inertially driven mechanism which is independent of the rocking power source serves to rotate the container about its longitudinal axis as it is rocked, thereby greatly reducing the time required to thoroughly mix the paint within the container.
