Patent GB-294812-A (GB)
Abstract: 294,812. Electroflo Meters Co., Ltd., (Republic Flow Meters Co.). Nov. 4, 1927. Indicating; recording by co-ordinates.- A means for measuring boiler efficiency comprises an indicator or marker operated according to the carbon dioxide percentage co-operating with a scale calibrated proportionally to the reciprocal thereof, and a second indicator or marker operated according to the temperature of the flue gases co-operating with a temperature scale, the product of the reading giving the loss of efficiency. The scale is calibrated from the equations L=K.W.T.; W=f/P where L= percentage loss, W and T the weight and temperature of escaping gases, and P represents the percentage of CO2 in the stack gases. From these equations by substitution L=K'T. In carrying the invention into P effect a record-strip a driven by clockwork is caused to travel beneath three styluses b, c, and d operated respectively by a steam flow meter, a gas analyzer, and a pyrometer through rods x, y, and z, the styluses being carried by arms t slid ably mounted on a rod u. The three sections of the strip may be graduated at intervals to represent the steam flow, percentage of CO2 and stack temperature or the graduations m, p, and s may be marked' on a bridge piece v arranged across the record-strip. In juxtaposition to the scales p and s are scales p<1> and s<1>; the scale p<1> bears a reciprocal relation to the scale p and represents the factor W while the scale s<1> agrees with the scale sand each unit represents 100‹ of stack temperature and corresponds to the factor T. The percentage loss of efficiency is obtained by multiplying the reading of the graphs on the two scales p<1> and s<1>.

Title: Recording gas calorimeter
IPC: G01N25/42
Filed: 1932-10-25
Abstract: 399,326. Calorimeters. MASTERTON, W., 75, Warrender Park Road, Edinburgh. Oct. 25, 1932, No. 29802. [Class 97 (iii).] In a water-flow gas calorimeter each revolution of the gas meter initiates the supply to the calorimeter of an amount of water which is automatically corrected in accordance with atmospheric temperature and pressure. A measuring vessel C is filled from a pipe X and overflows through a tube W into the left-hand partition of a cup U and from thence through a pipe K to a bucket E, which is arranged to travel in a sleeve F and is secured on the end of a cord Q, Q1, Q2, passing round fixed pulleys L, M, and a pulley N, carrying a weight R, to the fixed point P. When the bucket E has received sufficient water to prime a syphon therein it is emptied and is thereupon lifted by the weight R, which descends to an extent controlled by the position of a bell B containing air sealed over water. An everready syphon D is secured to the cord Q2 and is lowered in to the measuring vessel C and syphons therefrom into the calorimeter through the flow smoothing chamber Y a quantity of water dependent on the position of the bell B. A curtain V descends with the syphon D and cuts off the water supply to the vessel C. At each revolution of the gas meter A contacts close the circuit of an electromagnet S the armature of which pushes the swivelling cup T into its right-hand position where it directs water from the tube W through the right-hand partition of the cup U and tube H into the bucket E. The latter when sufficiently filled overcomes the weight R, raises syphon D and curtain V, and operates lever Z pushing the swivelling cup T to the left-hand position, thus restoring the apparatus to its original position. According to the Provisional Specification the bucket E is replaced by a float in a chamber which receives the waste water from the calorimeter and is provided with a syphon. The latter maintains the chamber empty by syphoning the water over into a cup. At each revolution the gas meter opens a valve in the cup and drains the latter so that the priming of the syphon is broken and the liquid rises in the chamber and lifts the float.
