Abstract: LAZLO BAKO          SURFACE MOUNT COMBINATION LOCK  Abstract of the Disclosure A combination lock for luggage, for example, which may be surface mounted.  Dial gears and cooperable gears have separate axes parallel to the thickness of the lock.  In the on-combination position, hubs of the cooperable gears are aligned with openings in a slide that is moved relative to the hubs to permit an actuator to move a latch to its open position.  The latch may also be moved to its open position by a hasp, even when the combination is scrambled.  A shifter, which has an operator accessible at the face of the lock only when the hasp has been released by the latch, moves the slide and the cooperable gears as a unit, to disengage the cooperable gears from the dial gears for changing the combination.

Abstract: ABSTRACT            The circuit breaker contains a contact system and a blast device.  The blast device produces a flow of quenching gas required for the quenching of the switch-off arc in the contact system.  The blast device, which is assigned to the contact system, includes an annular piston and a movable cylinder.  The piston is sealed via a first sealing ring aginst the cylinder and via a second sealing ring of different diameter against a movable cylindrical bridging element of the contact system.            The circuit breaker also contains a one-way-action valve which is closed in the compression phase and opened in the intake phase.  The valve is formed by the two sealing rings which are located in the same plane.  They are arranged with axial play in annular grooves which are formed in the piston in flow paths for the quenching gas.  Between the sealing rings is arranged at least one spacer element.  The rings are supported in a way so that they are movable trans-versely to the main axis of the piston.

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of rolls displaceable axially in accordance with the rolled sheet width are arranged at the upper and lower sides or only one side of a pair of work rolls having a high flexural rigidity, such that the axes of the axially displaceable rolls are substantially in the same plane as the axes of the work rolls, so that the shape control of the rolled sheet is performed by the axial adjustment of the axially displaceable rolls.  Each axially displaceable roll has an axial end portion the diameter of which is gradually decreased toward the axial outer extremity or edge with such a rate that the reduction in radius of said axial end portion within the range of 100 mm as measured from the starting point of said axial end portion toward said axial outer extremity is at least 0.3 mm.  In consequence, the stress concentration at the axial end portion of the displaceable roll, as well as spalling and scoring, is avoided and the shape controllability is improved considerably.

The top layer comprises a batt or fleece of non-woven batting material.         Also disclosed is a method of making the papermakers felt wherein the lower and intermediate cloths are separately woven and then associated with each other so that the inner surface of the intermediate layer contacts the outer surface of the bottom layer.  The associating of the two layers takes place on a conventional fiber locker or needling machine associated with a conventional stretching device.  When both of the cloths have achieved substantially the same length, the non-woven web of synthetic fibers is needled into the two cloths through the use of the needling machine to produce the composite three-layered papermakers felt.

Abstract: PRUNING APPARATUS OF THE COMPOUND ACTION HOOK AND BLADE TYPE              ABSTRACT OF THE DISCLOSURE      The invention discloses pruning apparatus of the compound action hook and blade type.  At the upper end of a longitudinally-extending handle, a stationary hook is fixed and extends upwardly therefrom in a plane parallel to and offset from the longitudinally-extending plane of the handle, It defines a downwardly-facing arcuately-shaped limb-engaging-surface for engagement with a limb.  There is a movable blade which has a cutting edge and is operable to be reciprocated in an intersecting manner through cutting and return strokes with relation to the engaged limb and to the limb engaging surface of the fixed hook.  A lever is pivotally mounted relative to the hook and a link pivotally interconnects to each of the lever and movable blade.  The hook and movable blade and lever and link are each disposed contiguous to a common vertical plane.  A rope and pulley assembly operatively interconnects with the movable blade through the lever and link and has a free end extended to the lower extremity of the handle for effecting pivotal movement of the movable blade through the cutting stroke responsively to a manually effected pull.  Spring means effects movements of the movable blade through a return stroke.  An adjustable grip in the form of a manaully engageable member has a sinuous opening therethrough for the extension of the rope thereinto and therethrough and therefrom in the slip free positioning and grasping of the grip relative to the rope for the facilitating of the application of a force on and substantially parallel to the rope.
