Title: Method and means for salvaging and recycling the latent heat energy of exhaust steam

Abstract: METHOD AND MEANS FOR SALVAGING AND RECYCLING      THE LATENT HEAT ENERGY OF EXHAUST STEAM                 ABSTRACT OF THE DISCLOSURE A method and means for economically producing boiling hot condensate plus mechanical energy from exhaust steam whereby energy waste and thermal pollution from power stations is greatly lessened. Herein, a combination engine and hot condenser is inter-posed between the main turbine exhaust port and the vacuum condenser for the purpose of making the steam do work and thus bringing about condensation at its boiling point.  Since the latent energy of exhaust steam is enthalpic as well as thermic by nature, its extraction as mechanical energy greatly lessens heat release upon condensation.  The mechanical work produced by such an engine depends not upon expansion, as in a main turbine, but upon continuous force exerted by vapor pressure operating on one side of a piston having a vacuum on the other.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved process is provided for preparing acyloxysilanes. The process involves conducting an aliphatic carboxylic acid in vapour form upwards from the bottom of a column countercurrent to the flow of a chlorosilane in which the carboxylic acid is introduced into the column at such a rate that the carboxlic acid does not exceed 1.3 mol per gram of Si-bonded chlorine in the column while removing the acyloxysilane from the bottom of the column.  The process is carried out in the absence of iron or iron complexing agents, is conducted in the absence of solvents, with very short reaction times with excellent yields of acyloxysilanes with very low concentrations of a cyloxysiloxanes.  These products may be mixed with diorganopolysiloxanes to prepare compositions storable under anhydrous conditions but which care upon exposure to water to elastomeric solids.

Abstract: ABSTRACT OF THE DISCLOSURE           Coking coal is preheated and dried by passing hot vapors into a generally vertical flue channel, then passing comminuted coal into the same channel, the vapors being blown with a flow speed to move the coal upwards in the channel and passing at about the midpoint of the channel a mixture of hot combustion gases and additional hot vapors branched off from the other hot vapor line into the flue channel so as to cause further heating and moving of the coal, the further heating being carried out in a uniform and gentle manner.  At the end of the flue channel the coal and vapors are separated and the coal is recovered while the vapors are recycled into a blower and therefrom into the vertical flue channel with a branch leading part of the vapors into a mixing chamber with the combustion gases so as to lower the temperature of the combus-tion gases when the same are passed into the flue channel.

Abstract: ABSTRACT OF THE DISCLOSURE:           The device is conventionally associated to a cigarette packaging machine and comprises a hopper for successively distributing individual layers of adjacently disposed cigarettes into transferring means which successively transfer each layer into compartments intermittently moved in front of said trans-ferring means.  A plurality of layers are superimposed in each compartment to form a bundle to be fed to the wrapping means of the packaging machine.  During the transferring, the layers are compelled to pass through a passage delimited by side guiding members and by an upper and a lower light-transparent guiding plate, said passage having a width substantially equal to the width of a layer and a height substantially equal to the diameter of a cigarette.  The upper plate has a slot in the direction of the transverse dimensions of the passage and this slot is subjected to the light rays generated by a light source trasversally disposed relative to said passage and above said slot.  The lower plate rests on a mounting having a number of built-in seats each aligned with a cigarette of a layer and each housing a photosen-sitive element.  Should a defective layer be lacking of a cigarette a light ray energizes the photosensitive element provided in the position corresponding to said lacking cigarette so as to operate, through conventional cyclic and memory means, the ejection of that bundle containing said defective layer.

Abstract: Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure. Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings. The loading apparatus is pivotally mounted. Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded. The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: Material Braking Apparatus Abstract A braking apparatus is provided for a supply spool whereby material drawn from the spool will have a relatively uniform tension.  The braking apparatus includes a follower roller in contact with the material on the spool and a brake portion in adjustably controlled braking contact with a brake rotor mounted for rotation with the spool.  The follower roller follows the decrease in the diametral amount of material on the spool and simultaneously moves the brake portion toward the center of the brake rotor wherein a uniform braking force on the spool is maintained.  In one embodiment, the supply spool is mounted on a shuttle of a cable-winding apparatus so that as the shuttle rotates, centrifugal force will act on the follower roller to urge a roller against the material on the spool and to move the brake portion toward the center of the brake rotor to maintain constant force on the material being withdrawn from the spool.
