Title: Filtering device
Inventor: BUCHNER DANIEL C
IPC: F16K31/524
Filed: 1980-07-21
Granted: 1982-08-03
Abstract: Disclosed is a filter for use in a faucet of the type having a removable cartridge member receivable in an underbody member, the cartridge member carrying a cam member, at least one cam follower member and a valve member actuated by the cam follower member upon movement of the cam to control fluid communication between a spout and a source of water.  The filter member is removably attached to a projection on the valve member and moves with it within a passage in the underbody member through which water flows from the source.  By this means, large particles are prevented by the filter from entering the faucet.  The filter comprises an inner annular member, an outer annular ring member, and a plurality of flat web connecting members extending radially between the inner and outer annular members.  The inner annular member has a through hole which tapers from a first diameter to a second diameter so that the inner annular member can be forced over a head portion on the projection whereafter it is latched thereon. Should the filter become clogged, it is easily removed and cleaned.

Abstract: S P E C I F I C A T I O N     TO ALL WHOM IT MAY CONCERN     BE IT KNOWN THAT I, WOLFGANG PRIEMUTH, a citizen of the Federal Republic of Germany of Postkamp 13, D-221 Itzehoe-Nordee, Federal Republic of Germany, have invented certain new and useful improvements in a WINDSCREEN WIPER of which the following is a description reference being had to the accompanying drawings which form a part of this specification.     ABSTRACT OF THE DISCLOSURE     A windscreen wiper has two strips of rubber-like material mounted in a separate holder one each side of the actual wiper blade to store and distribute a cleaning fluid over the windscreen surface.   Each strip is formed with a series of ribs inclined at a shallow angle to the length of the strip, these ribs forming channels which in operation sweep away dirt particles from the windscreen before these reach the blade itself.  In this way, abrasion of the wiper blade by dirt  particles is considerably reduced.

Abstract: Abstract of the Disclosure A heat absorbing body made from a mixture of water, Portland cement, cellulose fibers, and a foaming agent, with or without other ingredients such as water glass and sodium sulfate.  Polypropylene fibers may be used in place of part or all of the cellulose fibers.  Cellulose fibers (con-veniently reclaimed or recycled cellulose fibers) are preferably used because of their ability to absorb and retain relatively large amounts of water in the composition.          Various formulas are given for the mixture.  The material is used as a filling for the walls of fire resistant safes and storage boxes, and also for the construction of structural panels for furniture and building construction, and for cast-in-place walls and floors and roofs of buildings.  In addition to the ability of the material to absorb heat in case of fire and thus keep the contents of a safe or container or room cooler than would otherwise be the case, the material is useful for heat storage and retrieval, absorbing and storing waste heat or solar heat during a hot day, and giving up or re-radiating the stored heat when needed, such as during a cool night.

Abstract: Abstract of the Disclosure A management teaching game is employed to simulate a retail store environment in which a player must pay his opponent a certain amount of play money determined by the number of questions the opponent has correctly answered in a given category corresponding to a given player position.  The game includes a gameboard having a first and a second player territory, a pair of player pieces, a pair of dice, a question booklet, a computer for indicating the correct answer to the questions posed in the question book, and a score sheet for keeping cumulative totals of correct answers in each category and a predetermined amount of play money.  Each player must answer questions in specific categories when his player piece resides on a position in his own territory.  When a player's piece is located in a player position in his opponent's territory he must pay his opponent a certain amount of play money in proportion to the number of questions correctly answered by his opponent in the category of that particular player position.  Moves of the player pieces are determined by a roll of the dice. Play is over when all the questions in all of the categories have been answered by both players.  The winner is the one who obtains the greatest amount of play money.  The more correct answers a player knows to questions in each of the categories, the more likely it is that he will win.
