Abstract: ABSTRACT OF THE DISCLOSURE        Addition of CF4 or C2F6 to SF6 for use as the arc-extinguishing gas in a gas blast circuit breaker results in a high dielectric strength breaker employing the gas at high operating pressure, without need for excessively heating the gas.  The breaker thereby exhibits increased speed of thermal recovery and dielectric recovery.  Carbonization is also reduced since the mixture forms stable CS gas, instead of solid carbon, in the presence of an arc.

Abstract: Abstract A test tube cap assembly for centrifuge rotor tubes.  A stem member slidably moves within a crown member to exert a direct force on a bushing to securely grip the upper portion of a test tube located within the crown member.  The stem member and the bushing have generally mating frustoconical surfaces to provide a wedging action on the upper portion of the test tube.        The wedging action on the upper portion of the test tube.  The wedging action serves to not only seal the tube, but also support the upper end of the test tube by restraining the centripetal side of the tube from pulling away from the cap.  The operation of the cap assembly is enhanced by the hydraulic forces exerted from within the test tube by the contained liquid.

Abstract: ABSTRACT OF THE DISCLOSURE A tool is provided herein which is intended for use in conjunc-tion with carrier machinery, primarily a rockbreaker, for example, a dig-ging machine.  The tool includes two axially aligned substantially elon-gate members.  One of such elongate members may have one end introduced into the carrier machinery with its other end projecting out of such machine.  The other, protecting end may be disposed in a central recess in the second elongate ground engagement member.  The second elongate ground engagement member has an external abutment at that upper end.  A third member includes a body having an aperture mating with the external circum-ference of the second elongate ground engagement member.  The third mem-ber is secured relative to the rockbreaker unit by means enabling the third member to slide relative to the length of the second elongate ground engagement member between an upper limit position wherein it engages the external abutment on the second elongate ground engagement member, and a lower limit position, the third member surrounding the second substantially elongate member, the third member being so slidable by relative displace-ment of the rockbreaker unit with regard to the second substantially elon-gate ground engagement member.  When the carrier machinery is in operation, it impacts the engaging end of the first member, thereby impacting the second member, which may operate as a plunger for producing holes in the ground.  The second elongate ground engagement member is driven into the Abstract  (cont'd) ground in consequence of a series of short impacts of the carrier machinery on the first member.  Because of the interconnectors, the second  elongate ground engagement member is pulled out of the ground when the hole has the required depth.  The engagement or lower portion of the second elongate ground engagement member may comprise different tools for different pur-poses.  The structure of this invention therefore provides a tool whose services life and speed of operation are substantially greater than has been possible heretofore.

Title: Shaft assemblies for golf clubs
Inventor: MACDOUGALL IAN C KNOCKBRECK AV

Granted: 1982-07-06
Abstract: ABSTRACT  OF  THE  DISCLOSURE            A problem in golf club manufacture is the very large number of different shafts required to make sets of clubs with different shaft flex characteristics. The invention teaches how it is possible to greatly reduce the number of different shafts  used in a set by defining the shaft flex characteristics in terms of the EI value of the shaft. Recognising that the EI value at a section, that is, at a distance from a selected datum, controls the amount of deflection and hence flex characteristics the invention teaches how it is then possible to use a single master shaft throughout a set and by altering the distance from the datum, and hence altering the EI values a second and a third set and so on , having flex characteristics different from the first set can be produced from identical master shafts or shaft blanks.
