Title: Actuators for valves for pressurised dispensers
Inventor: BUTCHER ROGER A
IPC: B65D83/14
Filed: 1977-02-10
Granted: 1978-09-26
Abstract: A B S T R A C T       A tilt-type aerosol dispensing valve is made child-resistant by arranging that the actuating button is axially movable between a free position ( in which it can be operated ) and a locked position in which parts of the button engage part of the valve mounting to prevent tilting.   For example the button may have a skirt which, in the locked position, fits over the central boss of the valve mounting cup.   The overcap can be arranged to push the button to the locked position automatically as the overcap is applied.

Abstract: ABSTRACT OF THE DISCLOSURE       A brush support combination is provided for dynamo-electric machines in which brushes are continuously urged against a commutator or slip ring.  Each brush is carried by a brush arm which is in turn supported on a lead terminal of the machine. The lead terminals may be supported on an open ended motor housing or on an end cap which closes the open ended housing.  The brush arm is formed of electrically conductive, flat, resilient stock which supports a brush at one end.  The other end is formed into a bight, the free end of which projects outwardly.  The bight ex-tends through an opening in the lead terminal, entry to which may be achieved through a throat communicating with the opening.  In use the bight resiliently engages the edges defining the opening to retain the brush arm and provide electrical contact with the terminal.

Title: System for logging highly deviated earth boreholes utilizing auxiliary sinker bar assembly

Abstract: SYSTEM FOR LOGGING HIGHLY DEVIATED EARTH BOREHOLES      UTILIZING AUXILIARY SINKER BAR ASSEMBLY         Abstract of the Disclosure.  A conventional logging instrument is adapted to traverse a slanted or deviated earth borehole on the end of a conventional logging cable.  A heavy, streamlined sinker bar is adapted to be fitted over the cable and to slide freely thereon.  Upper and lower stop clamps, separated by approximately 100 feet of cable, are provided on the cable with the lower stop clamp being located approximately 200 feet above the logging instrument.  The sinker bar is adapted to slide freely between the upper and lower stop clamps.  Since it is unlikely that the logging tool and the sinker bar will become stuck at the same time in a highly deviated borehole, one of two things can happen.  If the sinker bar becomes stuck, the cable passes freely through the center of the sinker bar without impeding the logging tool until the upper clamp reaches the limit of its travel.  If at that point the logging instrument is descending freely, it can dislodge the sinker bar with a gravitational force.  If the logging instrument becomes stuck while the sinker bar is free, the sinker bar will rest on the lower clamp and push on the logging cable to impel it downward.          By the concerted action n of the sinker bar and logging tool, the probability of reaching greater depths within the deviated bore-hole is increased.  A sprig or other such shock absorber is affixed to each of the clamps to prevent transfer of excessive inertial force during the operation of the system.     -1a--

In the preferred embodiments of the invention, the pads on the impression cylinder and the raised characters on the printing cylinders are arranged in correspond-ing helixes.  The impression cylinder, printing cylinder, and inking cylinders are all driven by motorized means which also drive  the spreader so that the fabric is spread tensionless.

Abstract: ABSTRACT OF THE DISCLOSURE     Fine grained fuel such as coal dust is gasified at an elevated pressure by passing the fuel from a supply tank which is at atmospheric pressure by pump means into a pressurized lock basin and therefrom into the gasifier, the fuel during such movement retaining its loose consistency.  This can be accomplished for in-stance by a solid piston pump which is only partially filled with the fuel.  Thus, agglomerations are avoided and the fuel is directly conveyed into the gasifier in flowable and fluidizable form without the necessity of being reconverted into a finely divided form.

Abstract: Abstract of the Disclosure A discharge outlet for attachment to the bottom of a hopper which has a longitudinally extending discharge open-ing between spaced inner edges of the outlet side walls.  An elongate control valve is mounted for rotation about a hori-zontal axis in the discharge opening between a pair of longi-tudinally extending parallel seats on opposed sides of the valve, and the control valve has its axis of rotation closer to one side of the control valve than to its other side where-by from a closed position weight of lading on the valve urges the valve in one direction of rotation to an open position in which lading is discharge about both sides of the control valve. The control valve includes a body portion extending longitudinally in the discharge opening, and a moment portion extending transversely and eccentrically relative to the axis of the rotation of the body portion.  The body portion includes a body portion edge which in closed position engages or is closely adjacent to a body portion valve seat located on or attached to the near side wall.  A moment portion valve seat is provided on or attached to the opposite side wall, trans-versely spaced from the control valve.  The control valve moment portion includes a moment portion edge which in closed position seats on or adjacent to the moment portion valve seat. The control valve is rotated to move the valve from the closed to open position in which the body portion edge is spaced from the body portion valve seat and the moment portion edge is spaced the moment portion valve seat.  The weight of the lading acting on the eccentrically mounted portion creates a moment about the control body portion which reduces the torque re-quired to move the control valve to the open position.  The control valve is preferably also movable to a metering posi-tion in which the body portion is spaced from the body portion valve seat, while the moment portion remains in engagement with or closely adjacent to an extension of the moment portion valve seat, to allow controlled lading discharge between the body portion and the body portion valve seat.  The body por-tion preferably has an arcuate upper surface with its center coincident with the axis of rotation and is movable from the closed to the open position without substantial upward dis-placement of lading.  The frictional resistance of the lading on the arcuate upper surface of the body portion effectively counterbalances the unbalanced force urging the valve to the open position, thereby to permit rotative movement of the control valve to open position with a controlled minimum torque.
