An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool.

A pet grooming tool, for use with a furry pet such as a dog or cat having loose hair and non-loose hair, is adapted for removing the loose hair from the pet. The grooming tool comprises an elongate handle portion extending generally along a handle axis, and a pet engageable portion secured to the handle portion. The pet engageable portion includes a blade portion and a plurality of teeth. The blade portion includes a blade edge. The teeth extend from the blade edge. The pet engageable portion is secured to the handle portion in a manner so that pulling the handle portion generally along the handle axis while the pet engageable portion is in engagement with the pet causes the blade portion to engage the loose hair of the pet and pull it from the pet without cutting or pulling the non-loose hair from the pet.

Aqueous-dispersed polymer compositions are prepared comprising polymerized therein (a) monovinylidene aromatic monomer (e.g., styrene), (b) acyclic conjugated diene monomer (e.g., butadiene), and (c) ethylenically unsaturated carboxylic acid monomer(s) (e.g. acrylic and or fumaric acid) and are further benefited by polymerizing therein (d) a cyanoalkyl ester of an ethylenically unsaturated carboxylic acid. The aqueous-dispersed polymers can also comprise polymerized therein an ethylenically unsaturated nitrile monomer such as acrylonitrile. The use of the cyanoalkyl ester, such as 2-cyanoethylmethacrylate (2-CEMA), results in latex polymers with improved performance in paper coating formulations. In particular, paper coatings can be prepared which have improved performance (i.e., wet and dry pick resistance) in offset printing applications.
摘要:
The present invention concerns a neutron dosemeter particularly applicable to the dosimetry of fast neutrons. According to the invention there is provided a composite detector material consisting of at least two fissile elements, the fission cross-section versus neutron energy response curves of which combine to match the kerma versus neutron energy response of a known biological material.

An integrated rockably released leverage snap fastening system is disclosed herein comprising a male snap and a rockable lever snap assembly wherein the rockable lever snap assembly may be removably fastened to the male snap to hold at least one item in place. To facilitate unfastening, male snap and rockable lever snap assembly cooperatively combine to create a class 1 lever system which may reduce friction and permit a user to rockably release the snap while reducing risk of damage to an item. Various embodiments of the present invention and a method of use are discussed herein.

Methods and apparatus provide an adaptive load balancer that presents a virtual data system to client computer systems. The virtual data system provides access to an aggregated set of data, such as files or web service objects, available from a plurality of server data systems respectively operating within a plurality of server computer systems. The adaptive load balancer receives a client data access transaction from a client computer system that specifies a data access operation to be performed relative to the virtual data system presented to the client computer system. The adaptive load balancer processes the client data access transaction in relation to metadata associated with the virtual data system to provide access to the file or service object within a server computer system, or to access the metadata. The adaptive load balancer can work in conjunction with other adaptive load balancers to dynamically adjust to demands for access to data by replicating and migrating data such as files or service objects as needed between the server computer systems to accommodate data access demands.
