Title: Screwdriver with replaceable nose for collated screws
Inventor: HABERMEHL G LYLE
IPC: B65D85/24
Filed: 1996-08-06
Granted: 2008-05-20
Abstract: This invention provides a driver attachment for a collated screwstrip in which a slide body is slidable in a housing parallel a longitudinal axis about which drive shaft is rotatable. The slide body has a rear portion and a removable nose portion. The housing and rear portion of the slide body form an integral part effectively permanently assembled and including a screw feed activation mechanism coupled between the housing and rear portion and which translates relative sliding movement and positioning of the rear portion of the slide body relative the housing. The nose portion is removable from the rear portion for ease of replacement with other nose portions adapted for use with the same or different sized screwstrips and/or screws. The nose portion includes a channel to guide a collated screwstrip generally transversely to the longitudinal axis of the drive shaft. The nose portion includes a guide mechanism to locate each successive screw advanced through the channel into axial alignment with the drive shaft for engagement therewith. The nose portion also includes a screw feed advance mechanism to advance the screwstrip through the channel when activated by the screw feed activation mechanism. The screw feed advance mechanism readily uncouples from and couples with the screw feed activation mechanism on uncoupling and coupling of the nose portion with the rear portion.

Abstract: Articles composites efficaces dans la séparation de mercure et de liquides. Ces articles composites peuvent être des supports poreux comprenant un substrat inerte sur lequel est immobilisée une répartition fine d'or combinée éventuellement à un revêtement de sel d'étain. Le support poreux peut être constitué par une bande fibreuse, poreuse ou en particules. Dans un autre mode de réalisation, ces articles composites peuvent être composés d'une membrane fibreuse et poreuse, dans laquelle sont entremêlés lesdits supports poreux qui peuvent se présenter sous des formes fibreuses ou en particules. Le procédé de séparation de mercure élémentaire, ionique ou organique contenu dans des liquides consiste à mettre en contact un liquide contenant du mercure avec un support et à faire passer ledit liquide à travers ledit support composé d'un substrat poreux et inerte et possédant une surface importante sur laquelle est immobilisée une répartition fine d'or élémentaire, à une vitesse régulée et pendant une durée suffisante pour que le mercure pénètre par sorption dans l'or élémentaire et produise un amalgame or-mercure immobilisé sur le support. Si un sel d'étain est également immobilisé sur le substrat inerte, on peut alors obtenir un sel de mercure-étain. Dans une étape ultérieure éventuelle, on peut récupérer du mercure élémentaire depuis le support et, éventuellement, le quantifier.

Title: A microbial pest control agent against the apple scab pathogen venturia inaequalis
Inventor: CARISSE ODILE
IPC: A01N63/30
Filed: 1998-07-07
Granted: 2007-04-03
Abstract: Apple scab, caused by the fungal pathogen Venturia inaequalis, is considered to be the most important single disease of apple worldwide and one of the most costly to control. Currently, the strategy for apple scab control relies on multiple applications of fungicides, often 8 to 12 fungicide sprays each growing season. These sprays represent an appreciable input of costs to growers and additionally, they can have a substantial impact on the environment. A new microbial pest control agent belonging to the genus Microsphaeropsis has been isolated. The application of this agent after harvest inhibits the formation of pseudothecia of V. inaequalis and consequently reduces the amount of primary inoculum the following spring which will result in a reduced spraying schedule.

Abstract: Computer network method and apparatus provides targeting of appropriate audience based on psychographic or behavioral profiles of end users. The psychographic profile is formed by recording computer activit y and viewing habits of the end user. Content of categories of interest and display format in each category are revealed by the psychograph ic profile, based on user viewing of agate information. Using the profile (with or without additional user demographics), advertisements a re displayed to appropriately selected users. Based on regression analysis of recorded responses of a first set of users viewing the advertisements, the target user profile is refined. Viewing by and regressio n analysis of recorded responses of subsequent sets of users continually auto- targets and customizes ads for the optimal end user audience.
