Title: Improvements in or relating to steam boilers and feed-water apparatus therefor
IPC: F22D1/24
Filed: 1931-08-25
Abstract: 388,799. Steam-boiler sedimentcollectors. WOOLNOUGH, W. H. and SENTINEL WAGGON WORKS, Ltd., 20, Iddesleigh House, Caxton Street, London. Aug. 25, 1931, No. 23936. [Class 123 (ii).] A sediment-collector 13 stores feedwater under temperature and pressure conditions approximating to those in the boiler sufficiently long to allow sediment to be deposited, the feed supply nozzle 32 being adjacent to or surrounded by a steam supply opening 44 so as to inject steam from the boiler or superheater. The steam and water spaces of the collector and boiler are connected by pipes 30, 31. An open-ended cylinder 33 into which the feedwater is discharged provides a tortuous course for its flow to the boiler feed pipe 31. In modifications the collector is mounted directly against the boiler drum and has a central heating flue with an arcuate partition and baffles in the annulus thus created to provide a tortuous path for the feedwater. The feed pipe may pass through the boiler steam space or constitute an open trough therein. The feedwater supply may have steam mixed with it. In another construction the collector comprises a compartment of the boiler drum and has partitions of diminishing height forming successive chambers for the feedwater. Two collectors may be provided with valves enabling either to be brought into operation. In the form shown in Fig. 9 a pipe 38 connects the collector steam space with a superheater 36 and a non-return valve 39 is inserted in the boiler feed pipe 31, so that there is always a circulation through the superheater so long as feedwater is being supplied to the collector. A heating coil may be provided in the collector. Specification 328,342, [Class 123 (ii), Steam generators], is referred to.

Abstract: 666,058. Testing physical qualities of moulding sand. FIFE, J. G. (Meehanite Metal Corporation). Sept. 21, 1949, No. 24312/49. Class 106 (ii). Apparatus for determining the toughness of moulding sand comprises a holder 23 for the test specimen 13 and a pendulum 26 provided with a striker 21 shaped and adjusted in height as shown in Fig. 3 to break the specimen in shear. The residual energy of the pendulum after breaking the test specimen causes it to contact the striker 31 of a non-return pointer 25 moving it over a scale 24 which may be calibrated in arbitrary toughness units. For example, units comparable with those normally obtained by multiplying the compression strength of the sand by the deformation of the sand under a compression load. In order to preheat the test specimen a portable furnace may be placed over the holder 23 and removed immediately prior to the test. In a modified form of apparatus shown in Fig. 4 a furnace 30 provided with heating elements 15 and insulating material 19 is positioned beneath the base 10. A movable member 33 raises the holder 23 and specimen 13, from the interior of the furnace, as shown in Fig. 5, to the testing position shown in Fig. 4, when the test may be made as before, without cooling the test specimen appreciably. Tests may be made at various temperatures and the curves shown in Fig. 10 obtained in order to determine the characteristics of the moulding sand at various distances from the surface of the mould or core.

Title: Improvements in carrying out the conversion of carbon monoxide with hydrogen
IPC: C07C1/04
Filed: 1938-08-22
Abstract: 518,372. Hydrocarbons. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). Aug. 22, 1938, No. 24683. [Class 2 (iii)] In the production of hydrocarbons having more than one carbon atom (with or without minor amounts of liquid or solid oxygen-containing compounds) by catalytic treatment of carbon monoxide and hydrogen, gases which have already been submitted to the reaction are recycled in volume at least 20 times the volume of fresh gases supplied. The recycled gas is preferably cooled to or somewhat above the temperature of the entrance to the reaction space so that on admixture with fresh cold gas a suitable temperature is attained. Suitable catalysts are sintered iron obtained from iron carbonyl or by reduction of iron compounds, or nickel or cobalt or their alloys may be used ; they may be activated by adding thorium or magnesium oxide ; ruthenium catalysts may also be used. A litre of the reaction gases at the prevailing temperature and pressure may take 0.1-5 seconds to pass through a litre of the reaction space. The reaction may be effected in a number of catalyst chambers in parallel, each having a number of catalyst layers, and cooling gas, such as cooled gas from which the reaction products have been removed, may be admitted between the layers. Alternatively, catalyst chambers may be arranged in series, the reaction products being separated at points between successive chambers. In the apparatus shown, fresh cold gas and hot recycled gas from a pump C are mixed at A and pass through a mixer B and (initially) a preheater J to a reaction chamber D containing a catalyst layer E. The reaction products pass through a highpressure steam boiler F, being thereby partially cooled and are returned by the pump C. A small part is branched off to a cooler or absorber G for recovery of the reaction products which are. drawn off from a separator H. Two detailed examples are given : in the first it is mentioned that the initial gas mixture has been treated to reduce its sulphur content to less than 5 milligrams per cubic metre, and the catalyst is sintered iron from iron carbonyl; in the second it is mentioned that the contact time per passage through the catalyst is 0.75 second.

Title: Improvements in or relating to electric fault alarm circuits
Inventor: BRADSHAW PHILIP JAMES
IPC: H04M3/08
Filed: 1954-08-25
Abstract: 747,547. Fault indicators. STANDARD TELEPHONES & CABLES, Ltd. Aug. 25, 1954, No. 24691/54. Class 38(5) A fault-detector of the general character disclosed in Specification 612,362 [Group XXXVI] is adapted to monitoring voltages as low as one volt by incorporating in the detector circuit a themistor the heating coil of which is.connected in the circuit to be monitored. Thus in Fig. 1B, the latter is connected to the terminals 1, 2 which includes the heater RH of the thermistor TH and, where higher voltages than one are to be monitored, a resistor R1. The thermistor element RTH is connected along with resistor R2, R3, R4 to the terminals 4 and earth of an H.T. supply, the ohmic values of resistors R3, R4 being so selected that a substantiallyconstant potential appears at the junction .3. The junction at R2 and RTH is connected over a rectifier MR1 to a conductor 5 common to a, number of similar circuits to be monitored and leading via a switch SW and alarm relay RLA to a tap 2 on a potentiometer P1, which is also connected between the terminal 4 and earth and shunted by a further potentiometer P2. Switch SW has two arms a, b and three positions, position 3 being for calibrating purposes in which a circuit MR3, R6 simulating MR1, R2 is supplied with calibrating potential from P2 and the latter is adjusted until meter Ml indicates the voltage required for R2 below which an alarm should be given. In position 2, P1 is adjusted so as to produce operation of RLA, whereupon the switch is placed in-position 1 for normal monitoring. The contacts rla-1 control the alarm relay proper RLB. Numerical figures are given in the Specification. With normal operation, the thermistors keep the potential of conductor 5 high so that each rectifier is blocked, but if failure occurs, the corresponding thermistor cools and its resistance rises so that, the p.d. across R2 drops and MR1 conducts, so enabling RLA, RLB to operate.
