Abstract: DEVICE FOR MIXING BONE CEMENT                 ABSTRACT OF THE DISCLOSURE         A device for mixing methyl methacrylate monomer and methyl methacrylate polymer to form bone cement in a hospital operating room includes a bowl-shaped container, a replaceable resilient plastic bowl-shaped liner which fits in the bowl-shaped container, a fluid passageway formed between the liner and container and a deflector cap which covers the space between the upper end of the liner and the upper end of the container.          Exhaust openings in the side wall of the liner place the interior of the liner in fluid flow communication with the fluid passage-way.  The methyl methacrylate monomer and polymer are mixed in the bowl-shaped liner.  When an exhaust portion the side wall of the container is connected to a vacuum source the ambient atmosphere is drawn through an access opening in the deflector cap towards the interior of the liner to promote aeration of the bone cement reaction mixture and the excess methyl methacrylate monomer vapor admixed with air is evacuated from the mixing device through the exhaust openings, fluid passageway and exhaust port and thereby is prevented from escaping into the operating room.

Abstract: ANALOG SIGNAL SUMMING  CONFERENCE CIRCUIT            Abstract of the Disclosure This specification discloses a telephone conferencing arrangement employed with a plurality of conference interface ports in a time division multiplex (TDM), private branch exchange (PBX).  Each port receives from the PBX the TDM conference signal of a respectively associated conferee and transmits an analog version of the conference signal to the conferencing system.  Conferencing is achieved by combining the analog conference signals into a plurality of composite signals which are subsequently recombined via resistance-value related conductive paths with the uncombined analog conference signals in selectable transmission phases and amplitudes so as to provide at the receiving terminal of each conference interface port a composite signal comprised of the selectably phased conference signals transmitted by the other conference interface ports.  Thus, when the PBX retransmits to the conferencing system a portion of each of the received composite signals, the retransmissions tend to cancel each other, thereby preventing regenerative instability in the conferencing system.

Abstract: Abstract of Disclosure -- A water based rubber resin pressure-sensitive adhesive produced by mixing a high solids resin solution on with an isoprene containing latex together with a small amount of carboxylation at a pH of at least about 8.  The tackifier resin is added to rubber latex in a high solids resin solution in an organic solvent.  Preferably this solution contains a small amount of a polar solvent such as isopropyl alcohol. The carboxylation may be derived either from using a carboxylated latex or from using a carboxylated resin in the resin solution, or a combination of both of these.  The resin solution is dispersed in the water system of the latex in a finely divided state.  This prefer-ably is accomplished  by adding the resin solution to the latex system slowly with high shear agitation.

Abstract: ABSTRACT OF THE DISCLOSURE          A solid block elastomeric bonding element is interposed between the surfaces of non-elastomeric thermoplastic elements to be joined by a fusion bond.          The heat necessary for fusion bonding is obtained for optimum results by the incorporation of heat generating particles in the elastomeric bonding element.  The particles are indirectly heatable by a high frequency alternating magnetic field or other suitable field for heating the fusion bonding element to a fusion tempera-ture suitable for producing bonding of the non-elastomeric elements. A copolyester block elastomer bonding element is particularly useful for bonding polycarbonate, polyvinyl chloride or polyvinylidene chloride elements to each other, and a copolymer block elastomer is particularly useful for bonding polypropylene and high density polyethylene elements to each other.
