Abstract: LASER CAVITIES WITH GAS PLOW    THROUGH THE ELECTRODES         ABSTRACT OF THE DISCLOSURE         A uniform field electrode arrangement for exciting a laser gas in a high pressure pulsed gas laser apparatus so constructed to facilitate discharge initiation and smooth laminar gas flow.  The geometry of the electrode assembly provides for laminar gas flow through the discharge volume providing an optically homogeneous lasing medium.  Discharge initiation for pulsed operation is achieved using, for example, ultraviolet irradiation of the electrode assembly, corona discharge devices and radioisotope irradiation of the electrode assembly.  Independent of the type of initiatory discharge device used, the geometry of the assembly allows for efficient supply of initiating electrons to the discharge gap without interference with smooth gas flow through the optical cavity.  Mesh electrodes can be used to facilitate gas flow in a direction parallel with the direction of elec-trical discharge.

Abstract: S P E C I F I C A T I O N       METHOD OF SECURING A PERIMETER FENCE AROUND AN ICE             RINK WITHOUT EMBEDDING INTO GROUND                      ABSTRACT     With the great increase in the game of ice hockey there is demand for large numbers of lower cost portable ice rinks that can make dual use of recreational land.  Heretofore, the hockey "dasher" boards around the perimeter of the ice rink have had to be fastened by embedding into concrete or other special solid base in order to withstand the battering and collisions of players, resurfacing machines and hockey equipment as well as the expanding pressure of the ice as it is constantly melted and refrozen at its edges.  This has meant special preparations and difficulty in dual use of recreational areas as playing field, tennis courts, lawn area, parking lot, etc.  A method of securing the dasher boards into the refrigerated ice slab is disclosed so that no attachment is required into the ground below and no damage is done to it.  The ice is frozen as a continuous slab extending out for a foot or so behind the boards, the boards being supported on cantilever metal posts which provide bonding with the ice and provision for re-frigerant piping underneath and behind the boards and a cover box is provided which not only covers the bonding ice behind the boards but also acts as a cover for refigerant header pipes instead of the usual expensive trench.  Now for the first time unskilled personnel can completely assemble a refrigerated ice rink, make and maintain the ice, and then pack it away again at the end of the season, allowing for the alternate recreational area use to begin.

Abstract: ABSTRACT OF THE DISCLOSURE           Small amounts of mercury are removed from an aqueous electrolyte solution containing sodium chloride, by recycling the solution through a chamber at a temperature of about 5° to about 98°C while subjecting the solution to the action of a direct current maintained between an anode and a cathode bed both located above the lower portion of the chamber, the cathode bed being below the anode and comprised of conductive fibers having a diameter of about 40 to about 1,000 microns and extending throughout a complete cross-section of the chamber. Dissolved mercury is electrodeposited from the solution in the cathode bed and drops therefrom by gravitational force.  The mercury is collected in the bottom of the chamber and is periodically removed therefrom.  The invention also provides an electrolytic apparatus for carrying this process, which comprises a liquid containing means having liquid inlet means and liquid outlet means; an anode located at the outlet means; a cathode comprised of conductive fibers having a diameter of about 40 to about 1,000 microns, located at the inlet means; gas outlet means  mercury metal outlet means: and electrical means connected to the anode and cathode for passage of a direct current between the anode and cathode.  The invention is particularly suited for the removal of mercury contamination from liquid brine streams.

Abstract: Abstract A circuit for controlling the operation of a bi-directional motor having an excitation winding comprises a motor drive circuit electrically connected to the motor.  This drive circuit has first and second input terminals and a logic circuit for energizing the motor in a first rotational direction only when the first and second input terminals have coincident highs and in a second rotational direction only when the first input terminal has a high coincident with a low on the second input terminal.  There is a control connected to the first terminal for removing the high therefrom to de-energize the motor when its speed reaches a predetermined amount.  The practical utility of this arrangement is in a printer wherein a single motor is used to drive a carriage from left to right in the printing mode and from right to left during carriage return.  The arrangement provided a method stopping the motor when the carriage has reached its end of print position during the print mode and its home position during carriage return, and is simpler than former mechanisms for this purpose.

A loading station includes a movable loading carriage, a packer assembly having a reciprocable packer head, and a plurality of power actuators.  By positioning a container upon the loading carriage, the container becomes aligned with the packer assembly.  The power actuators are actuated from a main control panel to move the loading carriage toward and away from the packer assembly, open the closure, and reciprocate the packer head for inserting refuse into the container.  Subsequently, the closure is closed and the loading carriage is backed away form the packer assembly.  The container is then transported to the unloading station.  The unloading station includes a movable unloading carriage for receiving the refuse carrying container, and a plurality of power actuators.  By positioning the container upon the unloading carriage the container becomes aligned with the discharge zone.           The power actuators are actuated from a main control panel to move the unloading carriage toward a refuse discharge zone, open the closure, and move an abutment member carried by the unloading carriage into pushing engagement with the ejector head to discharge from the container.      Subsequently, the closure is closed, the abutment member carried by the unloading carriage into pushing engagement with the ejector head to discharge from the container.           Subsequently, the closure is closed, the abutment member is shifted away from the ejector head and the unloading carriage is backed away from the receiving zone.  Prior to being positioned on the unloading carriage, a filled container can be stored in the vicinity of the unloading station until needed.

Abstract: ABSTRACT Apparatus and method for heat-sealing a moving tubular liner or the like wherein the area of the liner to be sealed is repeatedly contacted by an opposing pair of elongated heat-sealing bars mounted for movement in unison in orbital paths relative to each other and to the liner passing therebetween.  The liner is passed in a straight line path and the repeated contact of the opposed sealing bars incrementally forms a continuous seal in the liner.  Through the portion of each orbital cycle of the bars where they are in contact with the liner, they have the same lineal rate of speed as the liner.  The intermittent contact enables heat-sealing of materials which would be damaged by the continuous contact operation of conventional heat-sealing equipment.
