Abstract: BLOW BACK PREVENTION APPARATUS FOR A WOOD-BURNING STOVE        Abstract of the Disclosure A device for preventing blow back through the fuel loading door in stoves or heaters in which the rate of combus-tion is controlled by restricting the supply of air to the combustion chamber.  When the stove is burning during normal operation the fuel loading door is closed and an air inlet to the combustion chamber is blocked by a pan member of the outer cabinet door.  A thermostatic damper controls the rate of combustion in the combustion chamber by restricting the quantity of air supplied via other air intakes.  When the outer cabinet door is opened to gain access to the fuel loading door, the pan member on the cabinet door is moved away from the air inlet to the combustion chamber thereby allowing additional air to enter the combustion chamber via the air inlet to the combustion chamber.  The additional air supplied via this air inlet increases the rate of combustion prior to the opening of the fuel loading door.  This increased combustion rate is unaffected by the opening of the fuel loading door, and the flames, smoke and other products of combustion are not blown back through the fuel loading door when it is opened.

Abstract: ABSTRACT The invention relates to a system for generating digital signals corresponding to functions of two variables, the functions corresponding to a selectable analytical relation and being of the type that can be described in a discrete form by a differential-equation or a simultaneous system of differ-ential equations and at least one boundary-condition or initial condition.  The invention provides such a system which is capable of generating the signals at a considerably higher rate than conventional systems.  The inventon includes a signal generator for forming binary signals for each of the two variables, the signals being representative for the differential-equation(s) and the at least one boundary-condition or initial condition.  Also included is a comparator for successively comparing, in the direction from the most signifi-cant bit (MSB) to the least significant bit (LSB), bits of equal significance of the two signals, each of which corresponds to one variable.  A rolling-point determinator is provided for determining a rolling-point on basis of at least one of the comparing operations,  The rolling-point is a point determined by the values of both variables and relative to which a preceding part of the function, considered to be graphically displayed in a cartesian coordinate-system, is rolled over 180° so as to obtain a next part of the function connec-ted to said preceding part.  Finally, the system includes a memory for memor-izing signals corresponding to at least the last-mentioned next part of the function in the form of bit-couples.

Abstract: SELF-SERVICE WAGERING SYSTEM           ABSTRACT OF THE DISCLOSURE           A single cash deposit may be used for multiple race/multiple day wagering.  As a receipt for the deposit, a ticket, having a form upon which a proposed wager may be entered, is issued with a system-generated transaction identification code.  The code corresponds to a memory location wherein information concerning credit balance and any outstanding wager is recorded for the transaction.  To place a bet, the ticket form is filled in with proposed wager information.  The ticket is then inserted into a terminal and read. The memory location corresponding to the code is accessed and any outstanding wager information contained therein is compared to the race results. If same coincide, indicating a winner, the value of the outstanding wager is calculated and added to the stored credit balance.  The proposed wager is compared to possible valid wagers on the upcoming race and, if same coincide, the proposed wager is accepted, the value thereof is deducted to update the credit balance, the previous transaction is closed out, and a new code corresponding to the new transaction is assigned. Information concerning the accepted wager and the updated credit balance is stored in the memory as a new transaction record, at a location therein corresponding to the new code.  The read ticket is retained and a new ticket is issued containing the new code, an acknowledgment of the credit balance, an acknowledgment of the accepted wager and a form upon which may be entered information relating to a further proposed wager on a subsequent race.  Thus, outstanding wagers are paid, completed transactions closed out, proposed wagers accepted and recorded, credit balances updated and a receipt for same issued, all in a single confidential automatic operation.
