Abstract: CHILD'S TOY AND GAME     Abstract of the Disclosure A child's toy which can also be used as a game where-in a simulated landscape includes a flower or mushroom mounted on a bellows thereon and a second flower mounted thereon.  The landscape includes an air channel therewithin which includes an intake valve, a passage communicating with the bellows and an outlet valve communicating with the flower.  The outlet valve region of the flower includes an elastomeric washer for receiving a balloon simulating a ladybug or the like, the balloon including a nozzle for substantially airtight communication with an insertion into the washer.  The sides of the balloon rest on the sides of the flower interior so that, upon inflation of the balloon by reciprocation of the bellows in standard manner, air will come into the inlet valve to the bellows and air channel and, upon contraction of the bellows, pass through the air channel and through the outlet valve into the balloon.  The balloon will thereby be inflated until the force of inflation causes expansion of the balloon wall and thereby exerts a sufficient outward force against the sides of the flower to pull the nozzle out of the washer.  The inflated balloon will now release the air therefrom through the nozzle and the outlet air jet will cause the balloon to be ejected further from the flower and fly away in known manner.

Abstract: COMBUSTION CHAMBER WITH SLAG DAM AND            DRAIN TROUGH     ABSTRACT OF THE INVENTION     Removal of molten slag from combustion chambers for combustion of combustible gases containing entrained slag-form-ing particulates, is frequently a problem since the slag tends to solidify in the tap-hole resulting in bridging and eventual pluggage of the tap-hole.  This invention eliminates this prob-lem by providing a dam around the periphery of the tap-hole of sufficient height to maintain a pool of molten slag on the in-clined bottom of the combustion chamber to a depth whereby said slag pool is an effective heat sink to maintain the molten slag in flowable condition, and by providing in the dam at least one inclined drain trough which over-hangs the tap-hole a suffi-cient distance to minimize contact of draining slag with the walls of the tap-hole.

Abstract: Abstract of the Disclosure Linear operation of a buried channel charge coupled device (CCD) is obtained by employing a bias charge in the input potential well of the CCD.  A charge signal proportional to an input signal is added to the bias charge by the "fill and spill" technique, this charge addition occurring in the linear region of the signal versus generated charge transfer characteristic of the CCD.  The charge signal is skimmed from the potential well for propagation down the CCD.  The potential well containing the bias charge is of substantially larger capacity than the potential wells of the CCD channel to insure that the latter can be fill to close to their capacity, that is, to obtain wide dynamic range in addition to the linear operation.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for measuring distance to an object. The system comprises a device for producing a high frequency sound impulse.  There is a receiver for a high frequency echo sound impulse reflected from the object.  A depth clock is connected to clock a counter.  An initiator for the depth clock initiates the clock at a first time corresponding to the time of production of the high frequency sound impulse.  The depth clock is stopped at a second time corresponding to the time of receipt of the echo sound impulse.  The content of the counter is proportional to the distance to the object.  A time delay prevents stopping of the depth clock until a predetermined delay after the first time.  A speech synthesiser produces spoken numbers corresponding to data supplied to the speech synthesiser. Data corresponding to the content of the counter are supplied to the speech synthesiser.  The system is safer than prior art systems as it does not need to be observed.
