Abstract: A condiment dispensing device is provided that, when activated by a user, may expel a condiment from a condiment cartridge secured within the condiment dispensing device. The condiment dispensing device includes a recess at its bottom portion in which a dampener member may be secured. When the dampener member is secured in the recess, the bottom portion of the dispensing device is flat, which results in the device being orientation within a holder in a consistent and predictable fashion. Because the dampener member may be made of a rubber or soft plastic, when the condiment dispensing device is placed in the holder, substantially less impact and noise are created than if the dispensing device were construed entirely made of metal.

Abstract: A clamp changing apparatus includes a coupling device capable of being secured on a robot arm and a clamp-holding device. The coupling device includes a main body defining a blind hole, a connecting portion defining a through hole communicating with the blind hole, and a piston. The connecting portion has a ring-shaped protrusion aligned with the through hole facing away from the main body. The protrusion defines a plurality of holes running through the lateral wall thereof, each of the holes receives a rigid ball in which the diameter is bigger than the depth of the hole. The piston is received in the blind hole and the through hole, and is slidable along them to push the rigid balls out of the protrusion. The clamp-holding device is capable of being fixed to a clamp and defines a latching hole corresponding to the protrusion.

Abstract: The present invention provides an apparatus and methods directed to a selectively engageable shaft locking device. In one embodiment, a shaft lock device is presented which enables the testing of the shaft and shaft drive device without engaging the drive mechanism into a fully operational state. Another embodiment provides the ability to return the shaft lock device to a storage state after full engagement. The present invention also provides for methods of testing a selective shaft lock device according to the disclosures contained herein.

Abstract: A caulking gun includes a gun body, a push rod, a push plate, an adjusting seat, a driving member, and an elastic member. Thus, the adjusting seat is movable in the gun body by rotation of the driving member to adjust the incline angle of the push plate by guidance of the tapered urging face of the adjusting seat so as to increase the incline angle of the locking hole of the push plate, so that the locking hole is locked on the push rod in a tilt manner so as to lock and move the push rod, without having to replace the push plate, thereby enhancing the lifetime of the caulking gun.

Abstract: A caulking gun includes a gun body, a push rod, a push plate, an adjusting knob, and a piston lever. Thus, the adjusting knob is rotated to move away from the push plate to increase the incline angle of the push plate, so that the push plate is locked on the push rod in a tilt manner to lock and move the push rod without having to replace the push plate, thereby enhancing the lifetime of the caulking gun.

Abstract: An automatically and smoothly continuously variable transmission, particularly for a bicycle, for transmitting input mechanical energy from a crank to the drive wheel. A ratchet, having an oscillatory, alternating motion member and a continuous rotary motion member, connected to the driven wheel, has a drive spring drivingly linked between the ratchet alternating member and the crank for driving the ratchet alternating member in one direction of motion. A return spring is linked to the ratchet alternating member for applying a return force upon the ratchet alternating member to return the alternating member in the opposite direction.

Abstract: Disclosed is an apparatus wherein the reciprocation of a piston which is achieved utilizing air pressure causes movement of a pawl portion provided on the piston, and this movement in turn causes intermittent rotation of a spindle. In particular, according to the present invention, a pair of pawl members are used, and a selector lever is provided to permit only one of the pawl members to cause the rotation of the spindle. When the pawl member to be actuated is thus selected through the action of the selector lever, selection can be made as to the direction of rotation of the spindle.

Abstract: A chainless feed system of a mining cutter-loader comprises a guiding rack mounted on a conveyer and meshing with gears rotatably mounted on the cutter-loader. The gears are operatively connected through a rotating mechanism with the hydraulic cylinders operable for rolling the gears along the guiding rack. The improvement of the rotating mechanism includes a carrier with a pawl adapted to engage the gear or come out of engagement therewith. For this purpose the pawl is pivotally mounted on the carrier which is operatively connected with the hydraulic cylinders arranged in opposition with respect to the pawl.

Abstract: A device for the measured or dosed dispensing of a putty-like or paste-like multi-component substance stored in separate containers includes a housing for holding the containers with a separate piston and piston rod unit for each container mounted in the housing. To prevent displacement of the piston-piston rod unit in the direction opposite to the dispensing direction, each piston rod is provided with a stop member. By pressing a hand lever pivotally mounted in the housing, a drive device connected to the lever grips the piston-piston rod units and moves them in the dispensing direction. The stop member permits movement in the dispensing direction but prevents the movement of the piston rod in the opposite direction when the hand lever-drive device is released.
