Title: Improvements in or relating to Portable Water Heating Apparatus.
Inventor: RICE ANSON SHERMAN
IPC: F01N5/00
Filed: 1919-12-06
Abstract: 136,542. Rice, A. S. Dec. 7, 1918, [Convention date]. Heating by electricity.-In a portable waterheating apparatus, particularly adapted for use on motor-vehicles, the heat required is derived from an internal-combustion engine both directly from the cylinder jackets and indirectly by means of electric heaters supplied with current from a generator driven by the engine, further heat, if desired, being derived from the exhaust gases. In the construction shown, which is applied to a motor-car, a clutch 38 is employed so that the transmission shaft 3 can be connected either to the rear drive 4 when the vehicle is running or to the generator 34 when the vehicle is stationary. In the former case, the water from the tank 14 is used in the ordinary way for cooling the engine 2 by circulating through an outflow pipe 9 to a pump 10, thence by a pipe 11 to the cylinder jackets, thence by a pipe 12 to the radiator 8, and returning by a pipe 13 to the tank. When the vehicle is stationary, and hot water is required, the radiator 8 is cut out of the circuit by means of a threeway cock 27 in the pipe 12, and the water returns by a pipe 26 to the tank 14. Arranged in or around the pipe 9 is an electric heater 31, and in or around the pipe 26 an electric heater 32 and an additional heater 22 warmed by the exhaust gases passed through a pipe 17. The exhaust gases may be by-passed by a three-way cock 18 through a short pipe 19, so that no heating at all occurs when the vehicle is running. In order to fill the tank 14 initially, the pipe 9 is connected by a three-way cock 23 to a supply pipe 25, the water flowing through the pump 10, pipe 11, cylinder jackets, and pipe 26 to the tank 14, which it reaches in a slightly heated state. Instantaneously heated water may be drawn off from the pipe 26 through a hose pipe 30 which is connected as an alternative to the tank 14 to the pipe 26 by means of a three-way cock 28.

Title: Improvements in or relating to contacting plate for liquid-liquid extraction tower
IPC: B01D11/04
Filed: 1949-11-29
Abstract: <PICT:0666544/III/1> <PICT:0666544/III/2> Apparatus for countercurrently contacting and concurrently settling streams of immiscible or partly miscible liquids of diffent densities, and particularly adapted for carrying out the process described and claimed in the parent Specification, comprises a tower 10 provided with a series of superposed perforated plates extending across the whole width of the tower, each plate comprising a central unperforated portion 1 and substantially diametrically opposed marginal perforated portions 4 and 5, stepped up from the central portion at different distances therefrom and connected thereto by unperforated vertical walls 3, the said plates being arranged in reversed relationship to each other throughout the tower, whereby the lower stepped up portion 5 of an upper plate overlies the higher stepped up portion 4 of the next adjacent lower plate, and the higher stepped up portion 4 of the said upper plate overlies the lower stepped up portion 5 of the said lower plate.  Vertical baffles 6 are arranged in the space between the central unperforated portions 1 of adjacent plates and in front of the opening between the said space and one or both spaces between the marginal stepped up portions 4 and 5. The tower shown is suitable for contacting liquids of low differential gravity, e.g. phenol and petroleum oil.  Phenol is introduced at the top of the tower and the oil at the base.  A head of phenol builds up above the perforated plate 5 of a jetting zone C, and a head of oil below the perforated plate 4, until this is sufficient to jet the phenol downwards and the oil upwards into a confined mixing zone A, where phenol from an upper plate and oil from a lower plate are mixed.  The unstable emulsion so formed flows over a central settling zone B and is prevented from passing into the jetting zone C by the vertical baffle 6.  A modification (not shown), suitable for treating liquids of high differential gravity, e.g. oil and aqueous caustic solution, may be considered as having the perforated plate 5 of the tower, illustrated in Fig. 1, dropped to the level of the unperforated plate 1.  It therefore comprises a series of two step plates in which each plate has an upper perforated step and a lower step perforated over that portion thereof which is directly above the perforated upper step immediately below.

Filed: 1936-11-13
Abstract: 485,174. Spray carburetters. WICKREMESINGHE, L. H. Nov. 13, 1936, No. 31026. [Class 7 (iii)] In a carburetter having a suction-operated air valve which controls a needle valve to regulate the fuel supply from the float chamber, the needle valve is located externally of the mixing chamber and the air valve is arranged so that when it is fully open it is withdrawn from the induction passage. As shown in Figs. 1 and 2, the air valve is formed by a hollow pivoted sector 4 which is exposed to the suction behind the mixture throttle 7 through a passage 8 controlled by a valve 9. The sector is provided with an adjustable counterbalance and when fully open lies within a chamber 6 in the induction passage 1 which is of square or rectangular cross-section. The needle valve 14 has a varying taper and operates in a jet 15 disposed between the float chamber 12a and a submerged jet 13 from which the fuel is led through an expanding passage to a jet tube 3 discharging into a narrowed portion 2 of the passage. The valve 14 is carried by a plunger 20 which is connected to the sector through a flexible connection such as a Bowden mechanism and when the sector is fully open the needle valve does not obstruct the jet 15. During closure of the sector the plunger forces fuel from a chamber 17 to the jet 13 to compensate for the fuel returned to the float chamber by the needle valve. In a modified construction, Fig. 8, the auxiliary throttle is formed by a slide valve 21 carried by a piston 22 exposed to the suction behind the mixture throttle through a passage 24 in the piston.

Title: Improvements in or relating to mechanism for use in a machine tool or the like for causing a support to move with respect to a fixed support
IPC: B23Q5/56
Filed: 1939-11-29
Abstract: 537,018. Screw-and-nut gearing. CINCINNATI MILLING MACHINE CO. Nov. 29, 1939, No. 31072. Convention date, Nov. 30, 1938. [Class 80 (iii)] To prevent backlash in a screw-and-nut mechanism for moving the work support of a milling machine &c. the lead screw is provided with a pair of nuts rotatable on the screw into engagement with opposite sides of a fixed abutment. The lead screw 13 rotatably mounted in the work support 12 passes freely through a fixed abutment 30 on opposite sides of which are nuts 32, 33 having bevel gear teeth 35, 36 meshing with a bevel wheel 37 having spur teeth engaging a rack bar 38 capable of a limited axial movement between fixed stops and pressed by a helical or rubber spring which normally urges both nuts into engagement with the abutment. When the table is moving towards the right under idle conditions or when the work is moving in the direction opposite to the direction of rotation of the milling cutter the nut 33 is the driving nut and the friction of the screw in this nut is greater than that in the nut 32 resulting in a preliminary slight turning of the nut 33 with the screw which through the gearing, turns the nut 32 in the direction to release its pressure on the abutment and thus the friction on the screw thread therein is released. When the table moves in the opposite direction the nut 32 forms the driving nut. When the table is moving e.g. towards the right and the work is moving in the same direction as the cutter for " climb " miliing, the engagement of the cutter with the work tends to move the screw axially increasing the friction between the screw and nut 32 and decreasing that between the screw and nut 33. The nut 32 turns slightly with the screw and, through the gearing moves the nut 33 towards the abutment. In this condition of working therefore, both nuts firmly engage the abutment.
