Abstract: A window operator handle foldable between an operable posi-tion for manual pivoting and a storage position, including a body with a manually graspable portion at one end and a recess in the other end, and a base including a longitudinal cylindrical portion having a central bore extend-ing completely through the base. The handle body recess is defined by side walls spaced a selected width, a top wall, and a wall at one end oriented substantially parallel to the operator drive shaft when the handle is in the operable position, with the base cylindrical portion having an outer diameter slightly less than the selected width. An operator drive shaft is securable in the base bore so that the an outer end of the drive shaft is substantially adjacent the handle body when the handle is in a storage position. The handle base is secured for pivoting relative to the handle body about an axis substantially orthogonal to longitudinal whereby in the storage position the base is substantially within the handle body recess. The body top wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and the body end wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position. A detent on the handle base is sharply tapered at one end, with the detent itself being narrower than the recess selected width by a selected amount. A detent spring has two legs connected at one end by a spring base secured at the other end of the handle body. In an unbiased position, the other ends of the spring legs are spaced apart less than the width of the detent, with those leg ends having a total width which is less than the selected amount and engaging the detent tapered end when the handle is in the operable position.

Title: Chimney lining former and compactor
Inventor: HASTI GEORGE A
IPC: E04F21/14
Filed: 1994-10-03
Abstract: ABSTRACT OF THE INVENTION      The invention relates to a chimney lining device which includes a shell member which telescopically embraces the exterior of a bell member.  A shell member of desired dimensions may be used in conjunction with a standard sized bell member for the lining of various sized chimneys.  Both the bell member and the selected shell member are formed of one-piece construction enhancing the durability and performance of the chimney lining device.  During use, the invention is generally lowered to the bottom of a chimney whereon a masonry mortar compound is deposited within the chimney covering the chimney lining device.  The chimney lining device is then activated causing the vibration of the bell member and the shell member.  The chimney lining device is then slowly raised within the chimney, which causes a uniform and compacted thickness of masonry mortar compound to be deposited to the interior walls of the chimney.

Filed: 1994-04-13
Abstract: The present invention involves methods of improving the Ligase Chain Reaction (LCRTM) amplification schemes by modifying at least one probe end so that the probability of the probe contributed to spurious ligation and signal development is greatly reduced.

Specific modifications include 3' phosphate blocking groups and nucleic acid overhangs containing an abasic site at the point of ligation. Further embodiments include probes modified to contain ribonucleotide moieties which, after amplification, can be cleaved by RNase to destroy the amplification products and reduce the risk of contamination.
