Abstract: ABSTRACT OF THE DISCLOSURE           A novel game is disclosed featuring a playing field having at least three lanes and divided into at least six rungs.          A game-piece representing the player may be positioned in any one of the three lanes and is free to move in a first direction from one rung to the next randomly generated obstacles advance in the opposite direction from rung to rung; the object of the game is for the player to avoid collision with the obstacle or obstacles.  In one embodiment the game simulates a football playing field, wherein the player's piece represents the running back of the offensive team and the obstacles represent defensive tacklers advancing towards the running back, in which case the object is to advance the ball the greatest possible number of yards and eventually score the maximum number of touchdowns.  In another embodiment, the game simulates an automobile race course wherein the player's playing piece represents an automobile in motion and the obstacles represent competitor's cars being passed, in which case the object of the game is to pass a predetermined number of obstacles.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an electrophotographic copy-ing machine of transfer type which includes, a main motor, a copy board on which an original to be copied is placed, an exposure lamp to which said original is exposed and a rotatable photosensitive element.  The surface of the photosensitive element is electrically charged, and an optical system projects a light reflected from the original onto the photosensitive element to form an electrostatic latent image thereon.  A developer means converts the electrostatic latent image to a visible toner image, and is transferred onto a transfer sheet.          A sheet supplier feeds the transfer sheet stored in a tray, and a carrier carries the transfer sheet fed by the supplier means.          A fixer melts and fixes the toner image on the transfer sheet.  In accordance with the invention the supplier comprises a supply roller adapted to be movable between a first position where the supply roller is in contact with the transfer sheet and a second position where the supply roller is not in contact with the transfer sheet and the supplier is driven by the main motor.

Abstract: Abstract of the Disclosure A method and apparatus is provided for removing large volumes of contaminants or for recovering valuable minerals present in trace amounts or greater quantities by ion exchange treatment of phosphoric acid liquids or the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mecha-nism. The resin bed is a folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed at times in the moving bed system, while the moving bed used is of a "folded" type having a maximum height approximately one-third that of conventional, unfolded countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.

Abstract: ABSTRACT         An automatic tray loading apparatus for cookies or the like in which cookies are divided into two rows with cookies in each row separated into groups of a given count and continuously conveyed to a loading station for loading into trays.  A pair of drop chute members are aligned with the rows of cookies and each arranged to receive a discrete cookie group dropped therein by a drop gate device.  The cookie group dropped into one of the drop chutes is moved laterally into close proximity to a second cookie group resting in the second drop chute to bring the cookie spacing into register with the spacing of cookie receiving compart-ments in the trays.  Drop gate slides for each drop chute are then activated to open chute outlet openings to drop each cookie group into an appropriate compartment of a wait-ing cookie tray.  A tray conveyor then carries away the cookie-filled tray and spots any empty tray below the drop chute outlet openings.

Abstract: A B S T R A C T              TELECOMMUNICATIONS SYSTEM INCORPORATING PORTABLE COMMUNICATIONS UNITS            The invention relates to the incorporation of an alternative to the public telephone kiosk or payphone in a telecommunication system.  It provides a telecommunication system having communica-tion terminals connected to it, and portable communication units for the users.  Each communication unit includes a transmitter and receiver enabling coupling to any of the communication terminals over a short range together with a credit meter adapted to co-operate with the communication terminal and to have its credit level adjusted by the telecommunications system's call-charge metering arrangements.  By such an arrangement individual users have and carry with them their own portable telephone units which are of similar size to a pocket calculator.  In order to make a call the user positions himself within some standard range (e.g. 5 meters) of any one of the communication terminals and then operates his communication unit to gain access to the telecommunications system by way of the communication terminal. The portable communication unit comprises a push-button dialler, a liquid crystal display and integral earpiece and microphone extendable to the normal spacing from the earpiece using an acoustic tube.  Access to the telephone system is gained by performing an interactive key code sequence using the communications unit.  When access is confirmed by the communication terminal the user keys in the required telephone number and when the call is established the terminal indicates call cost information over the reverse speech link.  The unit includes a PROM as a credit meter and the cost information cancels the requisite credit from the memory.

A drop of liquid flux is then applied to the apertures to hold the beads in place.  After the flux dries, the leads are inserted into plated-through holes in a circuit board, with the beads locating portions of the leads above the board.  Following wave soldering of the board, the beads are fractured with a sharp instrument prior to a cleaning operation which removes bead parts from the soldered assembly.  In this manner, the substrate is flexibly mounted in the board so that the substrate can be tilted without damaging it.
