Title: Improvements in hydromechanical power transmission means for vehicles
IPC: F16H47/07
Filed: 1938-07-07
Abstract: 517,519. Hydraulic transmission of power. TENNANT, W. J. (Aktiebolaget Ljungstroms Angturbin). July 7, 1938, No. 20197. [Class 69 (ii)] [Also in Group XXIV] In hydromechanical gearing particularly for a railway vehicle, in which a driven shaft 15 can be selectively clutched to a driving shaft 10 either by a clutch-disc 12 providing a wholly mechanical drive, or by a clutch-disc 13 providing a combined hydraulic and mechanical drive, the driven shaft 15 is at all times connected to the driven wheel 26 of the hydraulic gearing, e.g., a converter 24, by continuously meshing toothed gearing, e.g., 29, 16, including a one-way clutch 28, and the driving wheel 25 of the hydraulic gear is also connected to the engine through.another toothed gear-pair 21, 22. The provision of the one-way clutch 28 allows the hydraulic converter 24 to be stationary whilst the mechanical drive is in operation. The speed at which a change-over from hydraulic to mechanical drive is to be made in accelerating the vehicle from rest, which determines the starting tractive effort of the vehicle can be arranged to be any desired percentage of the maximum speed by a suitable choice of velocityratio for the wheels 29, 16, which latter are arranged to be readily exchangeable so that the gear can be adapted to suit different purposes as by the provision of greater or less starting tractive effort. By a suitable choice of ratio for the toothed gearing 21, 22 between the driving wheel 25 of the hydraulic converter and the clutch-disc 13 a given converter can be arranged to suit engines of different speeds. The driven shaft 15 drives the vehicle axle 19 through an idler 17. In a modification, Fig. 3, not shown, the clutch 12, 13 and gear-pair 21, 22 are arranged as a unit remotely positioned from the converter 24 and gear-pair 29, 16, and connected thereto through jointed shafts. The modification shown in Fig. 4 is the same as that in Fig. 2 with the exception that a two-speed mechanical gear is arranged between the driven wheel 26 of the converter and a parallel shaft 40 which drives the wheel 16 through a one-way clutch 41. A one-way clutch 42 is also included in the lowspeed pair 36, 38 of this two-speed gear, and overruns when the high-speed pair 37, 39 is clutched in at 43. In the form shown in Fig. 5, separate converters 24, 24<1> individually drive axles 19, 19<1> respectively through gear-pairs 53, 55; 53', 55<1> and one-way clutch 54, 54'. The wholly mechanical drive may, as shown, be to one axle 19' only, through a train 56, 53', 55<1>, or the axles may be connected together by a shaft 57. The hydraulic converter 24, Fig. 2, has fixed guide-vanes and may have adjustable impeller blades.

Generating combustion products under pressure.-A generator a<1> of products of combustion under pressure is used with motors such as turbines a<2> or other machines in a closed circuit from which at each cycle a portion of the gases are abstracted and a fresh charge is supplied. The generator has a displacer u the ends of the generator being connected through a regenerator R and a pipe i; the two faces of the displacer are not of equal effective area, the difference being sufficient to allow the displacer to do some work on the crank shaft on its up stroke. The hot gases at high pressure flow through the cooled pipe i to a reservoir d<2> and thence to the turbine and to the low pressure reservoir d<1>; the cooled gases at low pressure return to the cool side of the displacer through the valves g. The low pressure may be 10 atmospheres, the apparatus working between this pressure and 30 atmospheres. During each cycle a part of the gases are withdrawn through the auxiliary regenerators r<1>, r<2> at a pressure of 10 atmospheres and expand in a motor k to atmospheric pressure; the motor works the crank shaft. The fresh air and gas are supplied at a pressure of 10 atmospheres by pumps b, p to control pumps y<1>, y<2> which deliver the change to the generator a<1>. The withdrawn gases also pass through control pumps, reservoirs v, w, z being interposed between the control pumps and the generator. The pumps are driven from the shaft 3. The pressure in the pumps is balanced by connecting the rear chambers of the pump cylinders to the generator through the pipe 11.

Title: Improvements in evaporating and cooking plants
IPC: B01D1/28
Filed: 1945-08-10
Abstract: <PICT:0597136/III/1> Boiling plant, particularly for whaling ships, comprises a low pressure, live-steam cooker, a turbine for providing the low pressure steam by reducing the pressure of a high pressure supply, a compressor driven by the turbine, and an evaporator heated indirectly by the vapours evolved therefrom after they have been compressed by the compressor, the condensate thus produced providing make-up for the high pressure steam boiler.  Sea water, supplied through pipe 4, is evaporated in evaporator 1 and the steam evolved through line 6 is compressed in compressor 7.  This compressed steam is then supplied through line 8 to the heating coils 2 of evaporator 1 and the fresh water formed by its condensation is fed through line 9 to the ship's boilers.  The compressor 7 is driven by back pressure steam turbine 10 which is fed with high pressure steam from the ship's boilers through line 11, the expanded low pressure steam so produced being supplied to the whale cookers by means of line 12.  A conduit 13, provided with a valve 14, is arranged between lines 12, and 8 so that the evaporator coils may be supplied with exhaust steam from the turbine when starting up or in order to increase the rate of evaporation.  The coils 2 may also be supplied through line 15 with exhaust steam from the auxiliary engines on the ship.  A valved-conduit 18 is provided which bye-passes the turbine; this is put into service when fresh whale flesh is supplied to the cooker and the demand for heat thereof is a maximum.  Under certain circumstances, the amount of steam produced by the evaporator is greater than the amount which can pass through the compressor.  In this case, the excess steam passes off through safety-valve 20 and conduit 21 to condenser 23.
