In the embodiment having split fry pot, a single burner and immersion tube therefor is provided with a separate third pass baffle tube.

Abstract: A turbocharged diesel engine is described. The engine has a two stage turbocharger assembly including two low pressure turbochargers coupled in parallel and arranged in series with a single high pressure turbocharger. This allows all turbochargers to be of comparable dimensions for inter-changeability of parts. The turbochargers may be mounted on an enclosure which encloses the turbines and the exhaust gas duckwork which communicates with the exhaust pipe to insure that any leaking exhaust gas escapes to the atmosphere via the exhaust pipe. A cartridge is also described which contains the moving parts and which can be removed without disturbing the turbine housing.

The stream to be treated is introduced into a water-containing reaction zone which includes a packed bed of activated carbon to which an electrochemical potential is applied and to which ozone or hydrogen is fed at the same time. The cell further uses a contact electrode placed in the packed bed for supplying or removing an electrical current, and a counterelectrode disposed in a reaction vessel. The counterelectrode is electrically insulated from the packed bed of activated carbon. The cell further includes an inlet for feeding in liquid to be treated, an inlet for feeding ozone or hydrogen gas, and an outlet for discharging treated liquid and a further outlet for discharging waste gas.

Abstract: A drawer type hard diskdrive adapter including a mounting frame fastened to the computer mainframe, a casing covered with a top cover and moved in and out of the mounting frame to carry a hard diskdrive, the top cover having a hook hooked on a spring-supported sliding block in a sliding track at one side of the casing, and two projecting rods fitted into respective trapezoidal openings on the front side of the casing, the casing having a pivoted handle at the front side, which forces the projecting rods of the top cover out of the trapezoidal openings when it is turned upwards through 90.degree. angle, causing the casing separated from the mounting frame for loading or unloading the hard diskdrive.

Abstract: A structure or cooling a large cylindrical storage tank has the shape of an inverted funnel and is intended to be disposed over the tank receiving the upper portion therein and internal struts are provided to separate the funnel wall from the tank wall, The separation allows the entry of air into the funnel structure so that as the structure is heated by the sun air currents will rise through the funnel exiting the chimney which will result in an inflow of air into the funnel around the walls of the tank.

Abstract: An inductive output tetrode includes a cylindrical ceramic envelope within which is located an electron gun including a cathode and grid. An annular resonant input cavity into which a high frequency signal is coupled surrounds the envelope and is located adjacent the electron gun so as to provide a modulating electric field in the cathode-grid region to density modulate the electron beam. The input cavity is connected to two metal cylinders arranged immediately adjacent to the outside of the envelope. Metallic portions located within the envelope are co-extensive with cylinders with the material of the envelope 1 being located between them. These structures act as r.f. chokes to reduce high frequency losses from the input cavity. Tuning of the resonant cavity may be achieved by adjusting a tuning member which is at distance of quarter of a wavelength at the resonant frequency from the cathode-grid region.
