Title: One-step flea eradication composition
Inventor: MAFFIA ALBERT J
IPC: A01N59/14
Filed: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE Flea control is generally accomplished by one, or a combination, of chemical treatments either applied concurrently or over a period of time. The formulationprovided herein comprises a stable free flowing solid composition having a flea larvacide effective amount of boric acid and the pesticidedly active salts thereof; a flea adulticide effective amount of a mono-terpene (derived from citrus peel) selected from the group consisting of d-limonene, and piperonyl butoxide (synergist) and mixtures thereof. At the preferred concentration of active ingredients, the adult population of fleas is eliminated with about twenty-four (24) to forty-eight (48) hours. Comparable mortality of pupae is accomplished within the same period. Because of the low concentration of d-Limonene relative volatility of this monoterpene, virtually all of the active biocide that can pose a potential hazard to the inhabitants of the treated area is dissipated within the time required to affect complete kill, thus, obviating the need for removal of excess residual compounds. The significance of this property cannot be understated in regard to the safety factor (mammelian toxicity) afforded by this formulation to small children and pets.

Title: Attachment member setting tool and method for setting the attachment member
Inventor: SCHMIDLE JOSEF
IPC: B25D17/08
Filed: 1994-06-07
Abstract: Attachment members are used for securing insulation panels to structural components. Each attachment member includes a nail which is driven by a setting tool into the structural component. A connecting region on a guide tube of the setting tool generates a frictional force with a counter-connecting region of a hollow shaft in the attachment member when the nail is driven. By means of the generated frictional force it is possible to check if the attachment member is properly connected after the setting tool drives the nail. The frictional force between the guide tube and the inside surface of the hollow shaft is greater than the frictional force between the hollow shaft and the insulation panel.
