Title: Improvements in or relating to electronic counting rings
IPC: H03K23/82
Filed: 1945-02-16
Abstract: 593,706. Counting apparatus. NATIONAL CASH REGISTER CO. Feb. 16, 1945, No. 4029. Convention date, April 19, 1944. [Class 106 (i)] [Also in Group XL] In an electronic counter comprising a ring of gaseous valves, the cathode of each being connected to the grid of the next so that the firing of each valve prepares the next for operation by the succeeding pulse, the extinguishing connections between the cathodes of adjoining valves are arranged to pass an extinguishing potential surge in the direction opposite to the counting direction. After depressing key 50, valve 11 is fired by temporarily earthing the grid over key 31, the rise in cathode potential reducing the negative bias on valve 12. The next positive pulse applied over conductor 29 causes valve 12 to fire, the cathode potential rising suddenly and driving the cathode of valve 11 more positive to extinguish the valve due to the connection over rectifier 24 and condenser 25. The potential surge is attenuated over the nine other rectifiers in the ring and is ineffective at the cathode of the succeeding valve, the grid of which has been prepared by valve 12 firing. The rectifiers 24 are shunted by resistances 26 to allow condensers 25 to take up their normal charge. Specification 593,682 is referred to.

Title: Improvements relating to regenerators and like apparatus for heating air and gases
IPC: F28F21/04
Filed: 1945-02-22
Abstract: 595,150. Regenerators. POTTS, H. E. (Tesch, E. T. A.). Feb. 22, 1945, No. 4428. [Class 64 (i)] In gas heating apparatus in which the gas to be heated passes through a recuperator 3 in which it is heated by conduction of heat through separating walls from flue gases received from one of a plurality of reversible regenerators 1, 2, and subsequently passes through another of these reversible regenerators, the recuperator 3 has a variable auxiliary heat supply, e.g., a burner 14 which heats the gas to an extent such as to compensate, at least in part, for variations in the heating effect of the reversible regenerator through which the gas subsequently passes. Additional compensation may be obtained by adding heated gas from another source through a pipe 38 to the gas leaving the recuperator 3 or, if desired, leaving the regenerator, or adding cooler gas to the heated gas after it leaves the recuperator and before it enters the regenerator, or to the regenerator in use to heat the gas, through the inlet 36, 37, or to the outlet 9, 10. The addition of heating or cooling gas may be automatically regulated, e.g., by thermostatic elements and servo motors. The fuel supply to the burner 14 is controlled by a valve 25 operated by a servo motor 24 responsive to thermostatic devices 16, 15 in the outlets 9, 10 of the reversible regenerators. If desired, part only of the gas heated in the recuperator may be further heated in the regenerator, the remainder being used for another purpose. The reversible regenerators may be heated by very hot gases either produced by combustion within them, e.g., by burners 11, 12, or introduced into them.
