Title: Reversible pusher carriage for the transport of rolled material
IPC: B21B43/06
Filed: 1942-10-15
Abstract: 561,345. Rolling. LOEWY ENGINEERING CO., Ltd., and LANGEN, M. Oct. 15, 1942, No. 14447. [Class 83 (iv)] Relates to pushers, for moving bars &c. across the skid-bed of a mill plant, of the type in which the pusher element is mounted on the crank-pin of a shaft and consists in an arrangement of stops to rotate the crank shaft through 180 degrees to render the pusher operative in one direction or the other. The pusher 17 is mounted on the crank pin 15 of a shaft 14 journalled in the carriage 10 which is traversible on guides 11 below the skid-bed. A counterweight 18 normally maintains the pusher vertical and in the position shown in Fig. 7a, an abutment 22 on the counterweight contacts an abutment 20 on the carriage thus rendering the pusher operative for a direction of traverse towards the right in this Figure. If the crankshaft be rotated through 180 degrees an abutment 21 on the counterweight will contact an abutment 19 on the carriage and the pusher. will be operative in the reverse direction. To effect rotation of the crank-shaft a doublearmed dog 25 is mounted on one end and a finger 26 on the other end thereof, the centre lines of the dog and finger being 90 degrees apart. At a point in the track of the carriage the dog 25 engages a stop 23 and the crankshaft is turned through 90 degrees after which a second stop 24 engages the finger 26 to effect rotation through a further 90 degrees. The stop 23 is,pivoted at 28 for control by an arm 29 linked to operating mechanism which may be remote controlled, as from the rolling-mill pulpit. A series of stops, each with its own control may be located at different points in the travel of the' carriage to cause reversal of the crank-shaft at various points of the travel of the carriage. In a modification, an abutment is provided at one side of the counterweight only and in this modification the abutment at this side may be double to prevent swinging of the pusher in either direction. Should an attempt be made to move the carriage 10 in the wrong direction an inclined surface on the dog 25, that is inoperative during normal operation, swings the stop sideways to allow the dog to pass.

Title: Method and means ensuring contact between gasiform fluids and liquids
IPC: B01D47/02
Filed: 1959-04-30
Abstract: <PICT:0919162/III/1> <PICT:0919162/III/2> <PICT:0919162/III/3> <PICT:0919162/III/4> Gases or vapours to be reacted with liquids are formed into a froth by bubbling or passage through a nozzle and the froth is caused to follow a sinuous path to promote self-destruction. The reaction of hydrogen sulphide with ferric salt solutions to form sulphur and ferrous salts is referred to.  Froth forming liquids, e.g. alkyl aryl sulphonates, alkyl sulphates and the reaction products of a phenol and ethylene oxide may be added.  The preferred liquid:gas ratio is 1:10.  The apparatus shown in Fig. 5 comprises a cylindrical chamber divided into two compartments by a depending cylindrical partition.  Gas and liquid are formed into a froth by means of nozzle 51 and after passing from the outer to the inner compartment, froth remaining is destroyed by froth breaker 55.  This embodiment is suitable for use where the amount of liquid is small in relation to the gas since the liquid can be recirculated from the emulsion breaker through lines 56 and 59 and from the lower part of the chamber through line 60 and via pump 53 and line 52 to the nozzle together with quantities of fresh liquid, or liquid regenerated in 58, from the reservoir 54. Fig. 3 shows a similar chamber provided with a plurality of cylindrical partitions attached alternately to the upper and lower wall of the chamber.  Fig. 4 shows a system comprising three chambers connected for countercurrently contacting the gas and liquid, the frothing device being in this case a bubbling arrangement.  Fig. 1 (not shown) illustrates an annular bubbling device which extends round a cylindrical partition.  Fig. 6 shows another system in which parallel streams of liquid pass through two chambers while the gas passes therethrough in series; this is useful where the amount of liquid is large in relation to the gas. Specification 741,068 is referred to.

IPC: C14C3/20
Filed: 1945-06-12
Abstract: Water-soluble products useful in the tanning industry as tanning, dispersing or bleaching agents, in the textile industry, for dyeing, printing and dressing, as dispersing or reserving agents, and, in certain cases, as fungicides, are manufactured by the action of alkali bisulphites, in an aqueous medium and with gradual addition of a strong acid, on methylol derivatives obtainable by the action of formaldehyde on phenols of the general formula <FORM:0597099/IV/1> wherein R represents an alkyl, aryl, hydroxy-aryl, aralkyl, hydroxyaralkyl or cycloalkyl radical and -X- represents a simple linkage or -SO2-, and wherein the aryl nuclei may contain substituents such as halogen atoms or the methyl group, e.g. p-phenylphenol, 4 : 41-dihydroxydiphenylmethane, 4 : 41 - dihydroxy - diphenylpropane, 4 : 41-dihydroxydiphenyl sulphone and their homologues and halogen derivatives, or mixtures of phenols consisting wholly or mainly of those of the above formula.  The process may be carried out at temperatures not exceeding the boiling point of the reaction medium under atmospheric pressure (i.e. 100-110 DEG  C.), and the addition of acid is stopped when a sample diluted with water is stable at pH 1.5-2.5.  The pH is then adjusted to a value appropriate to the use for which the product is intended. In examples: (1) 4 : 41-dihydroxydiphenyl sulphone is boiled with formaldehyde and caustic soda in water, and the resulting solution is boiled with sodium bisulphite solution with gradual addition of sulphuric acid; (2) 4 : 41-dihydroxydiphenylpropane is similarly treated; (3) as in (1) with slight modifications in quantities and concentrations of reagents; (4) the sulphuric acid in (2) is replaced by hydrochloric acid; (5) a mixture of 4 : 41-dihydroxydiphenyl sulphone and 4 : 41-dihydroxydiphenylpropane is treated as in (3). Samples have been furnished under Sect. 2 (5) of products prepared similarly from: (A) p-cyclohexylphenol; (B) 4 : 41 - m - dicresylolsul - phone; (C) 4-o-cresylolpropane.

Abstract: 529,590. Automatic volume control. COOPER, A. H., and BLUMLEIN, A. D. May 19, 1939, Nos. 14922/39 and 4858/40. [Class 40 (v)] Gain control potentials corresponding to the amplitude of signals are obtained by applying alternating current to the cathode and plate of a rectifying valve and controlling the rectification by applying the signal to the grid, the desired potentials being produced in the output circuit of the valve. The cathode and anode of a valve 1, Fig. 1 (14922/39), are connected through a condenser 2 to the high tension winding of an alternating mains supply transformer 3. The control grid is fed from a diode which may be the detector of the receiver and A.V.C. potentials are taken off across a load resistance 4. Alternatively the grid may be fed from the output side of an IF transformer 6, Fig. 3, through an anode bend detector 8 operating with negative feed back over a resistance 9 in the cathode lead, the output across which is applied to the rectifier 1. As shown in Fig. 1 (4858/40), the cathode of the valve 1 is connected to a tapping 3a on the transformer 3 and the other end of the transformer remote from the plate of the valve is connected through a blocking condenser 19 and resistance 20 to a tapping 4b, the A.V.C. potentials being led off through leads from a tapping 4a. By arranging a suitable value for the resistance 20 the mains frequency currents in the lead 5 are cancelled out. Reference has been directed by the Comptroller to Specification 461,113 and U.S.A.

IPC: B64D1/04
Filed: 1942-10-24
Abstract: 561,646. Dropping bombs. SWIATECKI, W. Oct. 24, 1942, No. 14946. [Class 9 (ii)]' Each bomb is supported on its own carriage, and the carriages are arranged one above the other on endless chains. When the carriages descend, the bomb-supporting means thereon are tripped to release the bombs. The chains 4, 4<1>. are trained around sprockets 6, 61 on shafts 7, 71, and pivotally support tubes 3 to which are rigidly secured the carriages 10. The carriages, with their bomb loads, are held in the raised position by a cable 43 which is attached to a projection 12 on the uppermost carriage and wound on a drum 8 fast with shaft 7. When the bombs are to be dropped, an electromagnet 32 is operated to release linkwork 42 and a pawl 27 which normally holds ratchet 9 on shaft 7. Shaft 7 is thus free to revolve, and the chains, carriages, &c. descend, being guided in their movement by wheels 2, 11 thereon which engage guides 1, 1<1>, 5. As each carriage descends, an arm 26 thereon, pivoted on shaft 50 in projection 12, is knocked clockwise by a stationary pin 18. This clockwise. movement is transmuted by gears into a counterclockwise movement of arm 19, whereupon links 23 are moved away from over-centre position to retract hooks 24 from lugs 13 on the bomb. Bombing up is begun with the uppermost carriage in its lowermost position, each carriage being raised after it has received its bomb. The torque applied to the shaft 7 may be kept constant, whether the aeroplane is level or diving, by providing a tension P in the cable 43, the tension being W (1- cos alpha), where W is the total weight of the bombs and carriages and alpha is the angle of dive. This tension is produced by a known hydraulic or pneumatic device (not described) which is set in operation before the aeroplane begins to dive. Reference is made to Polish Specifications 17998, 18872 and 23415, Italian Specification 347,568, French Specifications 804,828, 831,665 and 831,666, and British Specification 553,910.
