Title: Improvements in or relating to building structures either under ground or wholly or partly under water
IPC: E02D29/077
Filed: 1926-01-19
Abstract: 261,943. Rauwald, F. Jan. 19, 1926. Excavating.-In the construction of subaqueous and underground structures, such as docks, locks, basins, underground railway tunnels, cellars &c., having walls enclosing an area, hollow sheet piles are placed by driving or erosion, without previous excavation or timber work, to constitute the permanent walls of the structure, and the ground enclosed by the walls is subsequently excavated as far as necessary. In the case of a railway tunnel below a street, the paving is first removed from one half of the street and small trenches dug along the edge and centre line. A wall a, Fig. 1, of sheet piling of hollow box section is then driven or sunk by erosion, and separate piles c driven along the centre line. Across the piles c and the wall a are placed reinforced concrete girders which, after partial removal of the earth thereunder, are anchored'to the side wall a and to the pillars c. On these girders is built the roof d, and the road-surface is relaid. The second half of the roadway is then taken up, a piling wall b driven along the edge, girders put in, the roof completed, and the road surface relaid. The space between the walls a, b is then excavated to complete the tunnel. The closed tunnel may be put under air-pressure if water is met. A lock is constructed by driving transverse walls a<1>, a<11>, Fig. 5, and longitudinal walls b<1> are strengthened by a coping d<1> of reinforced concrete, with anchor. ages el, f, Fig. 4. Subsequently the earth between the walls is removed to the depth required and a concrete bed g put in. The part a<11> of the wall a', all is then cut out. To lengthen the lock later, walls b<11> are driven to extend the walls b<1>. A caisson for foundations for bridges &c. is built by driving box piles a‹, Fig. 6, and connecting them by a concrete roof b‹ to form a closed caisson. An air-lock d‹ is provided, and stiffening girders e<0> and struts f<0>. This structure is then sunk by excavating in the interior until firm ground o, p is reached.

Patent GB-429522-A (GB)
Title: Improvements in or relating to purifying gases by treatment with copper ammonia solutions
IPC: C01B3/02
Filed: 1934-01-20
Abstract: <PICT:0429522/III/1> Spent ammoniacal cuprous solutions, obtained in purifying gas mixtures containing hydrogen from carbon dioxide, carbon monoxide and oxygen, are regenerated by subjecting them to a preliminary heating under pressure, e.g. at temperatures of 40--70 DEG  C. and then to a further heating at atmospheric pressure, and at a higher temperature to expel the absorbed carbon oxides, the time of heating in the first step being such that the reducing effect of the carbon monoxide compensates for the oxidizing effect of the oxygen and returns the ratio of cuprous to cupric copper in the solution to its original predetermined value.  The ratio of cuprous to cupric copper after regeneration is preferably 14 : 2 by weight.  Gases prepared by the catalytic reaction of water gas with steam and containing nitrogen, hydrogen, carbon monoxide and carbon dioxide enter a scrubber 10 by a conduit 12 where scrubbing with water under pressure removes most of the carbon dioxide but introduces a small amount of oxygen.  The resulting gas leaving the scrubber by a pipe 22 is further compressed by a device 24 and is scrubbed in a tower 26 by a cold ammoniacal cuprous solution, the purified gas leaving through a conduit 31.  The spent solution leaves through a valve 34 and is discharged into one or other of identical tanks 36, 38 heated by steam coils.  The solution remains for the time necessary for effecting the reduction.  The pressure is controlled by means of valves 111 in the conduits 109, while, if necessary, additional carbon monoxide may be supplied by means of the conduits 110.  After reduction the solution passes through conduits 50 and 70, down a tower 72 and through steam heated tubes 78.  During the rapid passage of the solution through the tower 72 and tubes 78, carbon monoxide and dioxide are driven off and pass away through the exit 73 and ammonia they contain being re-absorbed by the cooler solution at the top of the tower. The tubes 78 may be heated to 70--80 DEG  C.  The regenerated solution passing away through a conduit 90 is cooled in a cooler 92 and pumped by a pump 98, if desired through a further cooler 102, to the top of the tower 26 for re-use.  If desired a portion of the spent solution may byepass the vessels 36, 38 by means of a conduit 52, that portion passing into the vessels being subjected to a relatively strong deoxidation.

Abstract: 449,306. Centrifugal separators. BANYAY, J., 4, Eotvos utca, Budapest. Jan. 24, 1936, No. 2337. [Class 23] A centrifuge, particularly for separating fine solid particles from viscous liquids, has a downwardly tapering drum 1 with funnelshaped liner plates 5, and a ring of peripheral discharge valves with rotatable conical plugs 17 having their small ends directed outwards and carrying operating members. The funnel members 5 have plane bases 3 with openings 4 to which projecting outlet members 4<a> are connected. Ribs 5<a> are secured to the members 5 and are arranged to cause an air current through the drum. The lower end 24 of the drum has discharge openings 23 set at an angle so that they assist in producing the air current. The drum wall is reinforced by a steel wire helix 41. A cover 11 is secured to the drum by a nut 13 and the sludge discharge valves are seated in the cylindrical flange 14 of the cover. The conical plug 17 of each valve has an oblique bore 20 which can be brought, by rotation of the plug, into alignment with a channel 23 in the flange 14. The outer end of the plug carries a lever 19, 19<a>, the ends of which can be actuated when pins 27, 27<a> are depressed. The sludge is conducted to the valves by blocks 37 mounted on a ring 34 having a wedge-shaped groove. The mixture for treatment is supplied through the tube 35 and passes through the inlets 16 ; it is then conducted by the guide cone 30 to the concavity 29 in the cover 11 and the space 10<a> where the first deposition of sludge is made. The liquid then passes inwards between the plates 5 and further separation occurs. The clean liquid passes through the outlets 4<a>, 23 and the sludge collects in the region of the valves 17. The supply is cut off and the pin 27 is depressed while the drum is rotated to open all the valves so that the sludge can be discharged. This action is assisted by the air current produced by the apparatus. After the discharge is completed the valves are closed by the depression of the pin 27<a> and the apparatus is ready for further operation.

Abstract: 676,384. Automatic voltage control systems. SIEMENS BROS. & CO., Ltd., and DOUBLE, H. S. Feb. 1, 1951 [Feb. 1, 1950], No. 2660/50. Class 38 (iv). In Fig. 1 the output terminals of a D.C. generator (not shown) are connected to busbars BB and its field winding, connected to bus-bars SF, is supplied from A.C. mains SM through a tapped transformer TR, the A.C. windings of saturable reactors CHA, CHB, and a bridge rectifier FR. To maintain constant the terminal voltage of the generator, control windings of the reactors are energized as follows: windings I in dependence on the output current of rectifier FR; windings III in dependence on the output voltage of rectifier FR; windings V in dependence on the A.C. mains voltage through rectifier SR; windings IV in dependence on bus-bar voltage through a bridge network VSN including barretters BY. Windings V are in opposition to the other control windings. Adjustable components to produce under or over compensating effects are provided to meet problems such as driving the generator by a motor supplied from the same A.C. mains, and employing the generator for battery charging. In the event of failure of a barretter the increased output of bridge VSN is sufficient to operate a relay T to disconnect windings IV and reduce generator field excitation to a safe value. Application to the voltage control of alternators is referred to.
