Title: Improvements in and relating to Apparatus for Liquifying Air and other Gaseous Fluids
Inventor: KNUDSEN HANS
Filed: 1903-03-16
Granted: 1904-03-16
Abstract: 6087. Knudsen, H. March 16. Gas and vapour turbines.-Air and other gases are liquefied in apparatus comprising a highpressure air-compressor B driven by a gas engine A, and a low-pressure air compressor F, F<1> driven by turbines, of which one C is rotated by vapour generated by the waste heat of the gas-engine exhaust and the cooling-water, and the other D is rotated by highly-compressed air as it escapes from the liquifier R. The hot gases of the gas-engine exhaust are led through a pipe a<1> into a chamber h<3>, Fig. 2, from which they pass through tubes h to an outlet h<x>, this arrangement being adapted to act as a silencer. The hot water from the various cooling-chambers, condensing chamber G, &c., is led through a pipe g<5> into the chamber h<4>, in which it passes round the tubes h to a pipe h<5> leading to a chamber i<4> having an outlet i<5>. The chamber i' contains tubes i<1> filled with sulphurous acid vapour or the like which has been vaporized by hot water, and this vapour passes through the tube i<7> and turbine C to the exhaust C<1> leading to the inlet g<7> of the chamber G in which the vapour is condensed by cold water passing through the tubes g' and from which the condensed vapour is led back to the tubes i<1> to be re-vaporized. The inlet nozzles c, of the turbines C, D are of the coiled conical form described in Specification No. 24,356, A.D. 1902, .and the buckets of the turbines are arranged as described in Specification No. 23,646. A.D. 1902. The supply of vapour to the turbine C is regulated by means of a spring-pressed valve i<10>, which is acted upon by the pressure of . the vapour in the tube i<7> to control the flow of hot water through the pipe h<5> into the vaporizing chamber i<4>. A safety-valve i<8> opens under excessive pressure of the vapour and allows some vapour to pass back into the condensing-chamber. The supply of air from the liquefier to the turbine D is regulated by two pairs of valves d, Fig. 10, which are kept from freezing by being alternately opened and closed by linkwork d<7>, d', and gearing d<12> operated from the main shaft E. A spring-pressed valve d<14> is acted up as by the pressure of the air in the turbine to control the position of the link d<7> on the slotted bar d<9> and so to regulate the amount of opening of the valves d<5>. The bearings of the turbine D consist of hollow lubricating-chambers d<17> connected through grooves d<18> on the axle. Freezing and escape of the oil are minimized by by means of spaces d<19> opening into the turbine and containing air at rest, and any oil which passes into the turbine is run off through a pipe d<22>. The pressure on the bearings may be reduced by rotating vanes d<20>.

Rope railways; rope grips.-Relates to rope grips of the kind in which the gripping-jaws are carried at the end of an arm d, Fig. 4, capable of turning about a pin c 4 so as to accommodate itself to varying arrangements of the guide sheaves f, and consists in operating the grip through the pin c from apparatus on the trolley frame, comprising also means for preventing tipping or tilting of the trolley on steep inclines. Three modifications are described in which the grip is actuated by the axial movement of the pin c. In one, Figs. 11 and 14, the movable jaw m is connected by links l to a sleeve g, sliding in the hub of the arm d, and normally retained in the position where the grip is closed, by a spring h. The pin c and the sleeve g are moved axially to open the grip by means of a lever p, Figs. 4 and 11, mounted on the trolley frame and actuated by contact with a fixed incline q. In the second modification, Fig, 17, the grip consists of levers n which close on the rope when separated. This separation is effected by means of screws s, which form bearings for the pivots n<2> of the grip, and which are operated to separate the levers n by means of a rack r engaging the toothed ends s' of the screws and actuated in a similar way to the lever p. In the third modification, the grip is closed by the drawing together of the levers n instead of by their separation. To prevent tipping of the trolley on a step incline, the weight above the traction cable i, Fig. 19, is balanced by a counterweight w, which may be in the form of a quadrant having the middle of the gripping-jaws as centre, the suspension pin v being guided in a concentric slot w<1>. A slight modification of this form is described, and also another in which the counterweight is adjustable on an arm projecting below the traction cable.
