Abstract: "HANDLE ATTACHMENT FOR AN IMPLEMENT HAVING AN ELONGATE HANDLE SHAFT" ABSTRACT OF THE DISCLOSURE         An   implement   such  as  broom  or rake  has  a supplementary handle attachment mounted upon an upper side of the conventional  shank  of  the  implement.    The  handle attachment includes a first hand grip section in the form of a bar parallel  to the shank and spaced upwardly from the shank.   A pair of further hand grip portions are attached to the bar at respective ends of the bar and extend therefrom upwardly  and  forwardly  toward  the  implement  head.    The further  hand  grip  portions  consist  simply  of  a  simple cylindrical  body shaped  solely to receive the hand of the user gripped therearound without any further handle sections at  the upper end.   The handle attachment allows a user to select the preferred hand grip locations to allow operation of the device without bending.

Title: Level control valve arrangement and water closet cistern
Inventor: YOUNES ABD E R M
IPC: F16K31/26
Filed: 1992-10-16
Abstract: LEVEL CONTROL VALVE ARRANGEMENT AND WATER CLOSET CISTERN         A B S T R A C T     There is disclosed a level control valve arrangement preferably for use in a water closet cistern for controlling the liquid level in the cistern or container.   The arrangement has a liquid inlet (3)  feeding an inlet chamber  (1)  and a movable valve member  (7,10)  mounted on a seating  (11,12)  and movable between an open position in which liquid flows from the inlet into  the  cistern  and  a  closed  position  in  which  liquid  is prevented  from  flowing  into the  cistern.   The movable valve member  is  biased preferably  by  a  float  arm  into the  closed position  in  response  to  liquid  in  the  cistern  rising  to  a predetermined level.  The movable valve member (7,10) is mounted in the inlet chamber into which water is fed from the inlet (3) and in the closed position the valve is acted upon by a head of water in the inlet chamber to maintain the movable valve member in the closed position.         The control system is distinguished by the use of water head pressure upon an upper conical surface of the movable valve member during closure thereof thereby increasing the compactness area upon its base.  When releasing the movable valve member the conical form of the valve member exceeds the water pressure on the movable member during closure and slackens the pressure on it during opening.           Advantageously,  such an arrangement ensures there is no leakage of water into the cistern,  the inlet valve is not affected by changes in water pressure of the inlet supply, and the  contact  area  of  the  valve  is  substantially  increased providing a considerably reduction of wear of the valve, particularly the rubber washer between the movable valve member and seating of the inlet chamber.           Conveniently,  the  speed  of  water  exiting  from  the expulsion valve opening is increased  to more quickly and easily clean a lavatory for example.

Abstract: ABSTRACT OF THE DISCLOSURE           A method  is  disclosed  for  operating  optical distribution networks, in which the modulated radiation of a  laser  is transmitted over an optical distributer to several  optical  reception  stations,  and  the  reception stations are connected back to the transmission station, through a monitoring unit and a return channel transmitter. In  order  to  permit  an  interruption  of  the  optical transmission path at an optical receiver, for service or measurement purposes,  without disconnection of all the other optical receivers supplied by the common optical distributer, each reception station is provided with an additional signal connection.   Through this additional signal connection, a signal is transmitted when service tasks are to be performed at the optical receiver.  This signal  indicates  to  the  transmission  station  that  no interference exists, and that transmission needs not be interrupted.   The monitoring unit transmits this message over the return channel transmitter to the transmission station.
