Patent GB-1419214-A (GB)
Title: Electric surface area meter
IPC: G01N7/04
Filed: 1974-05-01
Abstract: 1419214 Measuring surface area WESTING- HOUSE ELECTRIC CORP 1 May 1974 [1 May 1973] 19116/74 Heading G1N The surface area of a sample is determined by exposing the sample to a gas, cooling the sample and measuring the amount of gas absorbed electrochemically. The measurements are preferably carried out using a solid electrolyte gas concentration sensor/gas pump and may be performed either by measuring the pressure of gas before and after absorption or, preferably by passing a gas over the sample, measuring the concentration of gas by the sensor current and determining the surface area from the integral of the change of sensor current with respect to time while the sample is being cooled. The sensor preferably comprises a calcia doped zirconia tube with platinum or silver electrodes and the gas is helium with 6À7% oxygen; the oxygen being absorbed and sensed. The sample is cooled in liquid nitrogen. Gas from supply 10 passes through regulator 15 and flow meter 12 and over sample 13 (which is initially at room temperature). The gas then passes through the heated sensor 20 and to atmosphere via reservoir and outlet 31 which has sufficient capacity to prevent atmospheric oxygen reaching the sensor when the sample is cooled. A voltage is applied across the sensor and the resulting current (proportional to O 2  concentration) is recorded at 24. This current has a steady value 35. When the sample 13 is dipped into liquid nitrogen 30, the current initally drops sharply due to cooling of the gas drawing helium from reservoir 31 back to the sensor. It rises again to a maximum 40 when the gas temperature stabilizes and then drops as absorption takes place. When the sample has absorbed all the oxygen it can, the current is restored to its original value 35. A recording integrator is started at point 40 and the shaded area is proportional to the material surface area. The theory based on the BET theory is given.

Abstract: 354,013. Electric brakes ; fluidpressure brakes. KELLNER, G. W., 12, Riehlstrasse, Charlottenburg, Berlin. June 24, 1930, No. 19258. [Class 103 (i).] Braking power of an electromagnetic brake a controlled by a cut-out operated by the lever g is cut off when the wheels of a vehicle lock by an electromagnetic cut-out c in a circuit d independent of the electric brake circuit band supplied from an exciting machine e driven by the wheels to be braked or a centrifugal governor may be interposed in the circuit d. This arrangement may be modified to control a fluid-pressure brake. When a centrifugal governor is used it may be arranged to complete the circuit d when the speed is above a certain limit and cause the electromagnet c to maintain the braking circuit b until the speed falls below this limit or the centrifugal governor may be arranged to break the circuit d above this speed limit and the electromagnet breaks the circuit against the action of a spring when the speed falls. A fluid-pressure brake a<1> is operated by oil from a pump h<1> through a cock p. When not braking the oil circulates through a passage s. A cock r is maintained closed by an electromagnet c and motor e driven by the wheels until the wheel locks when the cock r is opened by a spring k and the oil under pressure is released back to the container o. The cut-outs and the cocks controlling the brake power may operate gradually.

A steam generator is adapted for firing by gaseous fuel in one combustion chamber and by solid and/or gaseous fuel in a separate combustion chamber. Six burner ports 44 for gas, e.g. blast furnace gas, are disposed in both side walls of a combustion chamber 2 having a closable outlet 45 and separated from a slag tap combustion chamber 1 by a partition wall 5. Upper and lower burner groups 31, 32 in the outer stepped wall of the chamber 1 comprise pulverized fuel nozzles disposed on either side of gas and air nozzles (Fig. 3, not shown). The flame from the upper group 31 of burners is largely burnt out before reaching the level of the lower group 32.
