Abstract: SOSTENUTO PIANO ACTION            Abstract of the Disclosure A sostenuto piano action is provided for upright pianos.          Each damper is provided at the top rear thereof with a rubber fitting having a catcher flange or tab thereon.  A pivoted sostenuto knife similar to that in a grand piano has a blade thereon which, upon pivoting of the sostenuto knife, will catch or engage the catcher tab or flange of each fitting to retain re-tracted such dampers as are in retracted position.  With the knife pivoted to sostenuto position and additional notes played thereafter the flanges will bump the backside of the knife, but will not be caught.  Spring biased elbows or hinges are provided in the damper levers to allow "breaking" of the levers at such time so as to avoid providing a strange feel to the pianist.          The rubber nature of the fitting prevents any noise at such time.

Abstract: "DRILLING STRING SHOCK-ABSORBING TOOL"                 ABSTRACT OF THE DISCLOSURE A shock absorbing tool is provided having a low spring rate deformable element disposed in an oil bath in a sealed, annular chamber formed between the barrel and mandrel.  The deformable element comprises an annular stack of alternating rigid washers and deformable rings.  The washers are operative to prevent the deformable rings from bridging the walls of the mandrel and barrel, which bridging would transmit shock load between them.  Thus the stack of rings function as a long unit to absorb the axial movement of the mandrel originating from the action of the bit on bottom.          One of the chamber seals is a floating seal, exposed to the drilling fluid outside the tool so that the pressure within the chamber is equalized with the hydrostatic bottom hole pressure.  As a result, the tool is not pre-loaded, when lowered to the bottom of the well bore, leaving the most effective shock-absorbing capability of the element available to absorb the axial thrusts of the drilling bit.

Abstract: INSOLES FOR FOOTWEAR          ABSTRACT    An odor absorbing insole or insock covering the inner sole of footwear has a bottom inner sole engaging open cellular resilient cushion layer, an intermediate nonwoven random fiber felt mat porous layer having the fibers coated with an odor and moisture absorbing chemical such as activated charcoal or silica gel, and a porous slippery abrasion resisting top fabric layer protecting the foot or sock of the wearer against discoloration or irritation.          The layers of the insole are laminated into integral unitary rela-tion by heat sealing or by binders which do not impede flow of air.          The alternating application and release of foot pressure on the insole as when walking will alternately compress and expand the open-cellular cushion layer to pump air through intermediate layer and abrasion resisting top layer for circulating air in the foot-wear around the foot into intimate contact with the chemical for efficient absorption of moisture from foot perspiration and des-truction of foot odors.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention involves a mechanism for simultaneous-ly retracting two separate latch bolts which have previously been extended by their individual separate mechanisms.  The individual mechanisms comprise a substantially conventional knob actuated latch bolt, and what is commonly called a lock-ing dead bolt.  There is a lever arm attached to the knob spindle and a bell crank arm on a thumb turn shaft of the dead bolt.  A flexible strip anchored at one end to the free end of the lever arm projects slidably through a swivelling sleeve on the free end of the bell crank.  By providing a stop at the extremity of the strip by rotation of the knob spindle and its lever arm the bell crank is induced to rotate and withdraw the dead bolt to unlocked position, at the same time that the latch bolt is withdrawn to open the door.          Conversely, when the dead bolt only is withdrawn, by rotation of the thumb turn shaft merely to unlock the door, the strip will slide through the swivelling sleeve.  The lever arm of the knob spindle remains undisturbed and the latch bolt, therefore, remains in extended position, holding the door closed until withdrawn by knob action.

Abstract: ABSTRACT OF THE DISCLOSURE           A snap-lock device, for securing a dispensing mechanism to the mouth of a container which has an annular bead about the mouth periphery, comprises a bead embracing ring having an axially extending annular recess open at one end of its axial extent to receive the bead.  An annular rib, formed with the ring adjacent the open margin of the recess, underlies at least a portion of the bead to prevent axial bead-ring disengagement.  A retainer element, engageable on the ring when installed on the bead, exerts a radial force against the ring and holds the rib in underlying relation to the bead.  The dispensing mechanism is mounted with one of the ring and element.  A rabbeted interlocking arrangement between the ring and element prevents their relative disengage-ment so that the dispensing mechanism cannot be removed form the container.  Therefore, the device can be used with pressurized barrier-type and aerosol containers.

The cartridge has complementary grooves formed along its base for slidable engagement with the handle flanges and a recess is formed between the grooves having sufficient clearance as to allow the protuberance member to fit therein.  Attempted use of the handle with other than a cartridge having such recess produces interference between the handle and the cartridge, thereby preventing slidable engage-ment therebetween.
