Abstract: There is disclosed a combination rotary and percussive portable tool driven by an electric motor. The percussive tool includes a reciprocating cylinder having embodied therein a reciprocatable piston striker. The cylinder is mounted in a guide tube which is spring loaded by a spring positioned between an internal wall in the housing and a cap removably mounted over an opening of the housing. The opening provides access to the housing in order to remove the guide tube and spring. With the guide tube resiliently mounted in the housing, the guide tube and its interface with the housing is much less affected by the vibration and thermal conditions developed during operation of the tool. In addition, the tolerances required to mount the guide tube in the housing do not have to be kept as tight as they would have to be if a conventional mounting arrangement using welds or other rigid fastening devices were used.

Abstract: A method of making mixed esters of phthalic acid for use as plasticizers for vinyl plastics. The ester mixture is characterized by having a low volatility while at the same time having excellent solvency characteristics. In its preferred form, the mixed ester is made by first reacting butyl alcohol or a mixture of butyl and octyl alcohols with phthalic anhydride in a mole ratio of about 0.80 to about 1.5 moles of alcohol per mole of phthalic anhydride. Next, an octyl alcohol is added in a stoichiometric amount based on unreacted acid groups along with 20 to 100 percent of the stoichiometric amount of octyl alcohol as excess. An esterification catalyst is added and the reaction mixture heated under vacuum at a temperature less than about 150 DEG C for a time period sufficient to carry the esterification to substantial completion.

Abstract: A leak-proof insert for sealing in a fluid passageway and which may be a plug for the passageway but in a preferred embodiment forms part of a nozzle assembly comprising a tubular sleeve (20), a nozzle (18) and a nozzle body (16). The nozzle and nozzle body are held in an assembled relation with their bores (40, 34) aligned by the tubular sleeve which encircles them. The sleeve provides a seal between the nozzle assembly and housing (10) into which the nozzle assembly is mounted, and also provides a seal between the nozzle and nozzle body. During use, when under working pressure, the tubular sleeve tends to flow and move both downstream and radially, forming seals between the nozzle assembly and housing; and between the nozzle and nozzle body, which seals tend to increase in effectiveness as the working pressure increases. The nozzle body described is a set screw enabling insertion in the housing and may have a chamfer (50) which engages a corresponding circular corner (52) of the housing, preventing downstream flow of the sleeve therebetween.

Title: Genetic reassortment of rotaviruses for production of vaccines and vaccine precursors
IPC: A61K39/15
Filed: 1984-06-26
Granted: 1991-07-31
Abstract: This invention relates to processes which are used to produce, isolate, and characterize human rotavirus/animal rotavirus reassortants and to produce live attenuated vaccines and vaccine precursors. In the present strategy there is involved the new use of either (1) high titer hyperimmune antisera or (2) monoclonal antisera to select reassortants with the desired human phenotype. A point of novelty is the finding that antiserum or monoclonal antisera alone, so long as it possesses high titer neutralizing activity against only the 34-38Kd glycoprotein or of the animal parent, is sufficient to use for selection of reassortant rotaviruses with human phenotype. Also, the novel products are live attenuated vaccine precursors and vaccines.
