Abstract: TURBINE BYPASS DESUPERHEATER CONTROL SYSTEM           ABSTRACT OF THE DISCLOSURE     An adaptive control system for controlling the temperature of desuperheated steam in a turbine bypass system.  In one embodiment of the invention, redundant temperature sensors downstream of desuperheating water sprays provide an indication of the actual steam temperature after desuperheating has occurred.  The highest value of temperature is automatically selected for control and to provide an error signal to a controller.          The controller output, indicative of the deviation from a desired temperature, is multiplied by a factor porportional to steam flow in the bypass system.  The multiplied signal is then utilized to porportionally position one or more water control valves to spray more or less water into the bypassed steam.  The control system thus automatically adapts itself to variations in steam flow.  Preferably, the steam flow is taken as the product of the position of a steam flow throttling valve in the bypass line and the steam supply pressure ahead of the valve.  Additionally, operating parameters such as temperature and differential pressures are monitored and continuously compared against limiting values to provide automatic protection action if any of the conditions being monitored warrant such action.

Abstract: ABSTRACT This invention relates to a process for the production of a coating for steel pipes, this consisting of a thermoplastic material, in particular poly-ethylene, in which a layer that is used for adhesion with the pipe surface is applied to the preheated steel pipe and a covering layer is applied on top of this, both layers, immediately prior to application, being extruded simultan-eously in tubular form or as flat strips which can be wound on.  The extruder head which is used for this extrusion process is heated to an operating tem-perature of approximately 170°C.  In order to improve the effectiveness of already familiar adhesive agents and thus the stability of the coating, it is proposed that during the extrusion process air is introduced into the inter-vening space between the pipe surface and the inner layer, this air having a reactive gaseous component, e.g., ozone, which reacts with the inner foil and forms adhesive groups, e.g., carboxyl groups.

Abstract: Abstract of the Disclosure A process is disclosed for the incremental enrichment of deuterium and/or tritium in a material which is suitable for the isotope exchange of deuterium and tritium with hydrogen.  An apparatus especially adapted for the implementation of the process is also disposed.  The novel process and apparatus for the enrichment of deuterium and/or tritium in water, in addition to a high transport speed for the molecules which participate in the isotope exchange, evidences a high enrichment factor for each enrichment stage and a high yield, so that, at a relatively small number of stages and low energy consumption, there is attainable an overall high degree of enrichment.  For each enrichment stage, water containing deuterium and/or tritium is introduced into a carrier gas flow, reduced and set to a hydrogen (H2) partial pressure of maximally 100 mbar.  Subsequently thereto, the carrier gas flow is conveyed along the primary side of an exchange wall which is suitable for the permeation of hydrogen, along the secondary side of which there is an additional carrier gas flow which con-tains a material adapted for the isotope exchange of deuterium and tritium with hydrogen in the gas phase thereof.  The hydrogen isotopes, deuterium and/or tritium, which permeate through the exchange wall, after the isotope exchange, are bonded with the material in reaction product.

Abstract: ABSTRACT          A high quality animal feed stuff is produced by thermal de-watering of liquid stillage obtained from fermentation of grain raw material and distillation of the fermenta-tion product. The liquid stillage is mixed with partic-les of already dewatered product and the mixture is granulated in a granulation device to form essentially spherical granules with a dry substance content of 50-70 % by weight, the major part of the granules having a particle diameter in the range of 2-6 mm, whereafter the granules are dried by being conveyed as a porous bed in a control path in contact with hot gas of a tempera-ture less than 100°C, and whereafter a part of the dried granules with a desired particle size are dis-charged and the remaining part of the granules after possible desintegration are recirculated to the granula-tion step. Since all the dewatering is carried out by drying with a gas of low temperature, waste heat of low value such as condensation heat from air cooled conden-sors     in the distillation plant can be used for drying the granules.

Abstract: Abstract of the Disclosure The invention provides a protective casing for a cube-shaped modular ceramic heat exchanger core, in which the core can easily be installed without danger of leakage between the fluid paths of the core, either while the device is new as its temperature changes, and subsequently as it is in use subjected to drastically altering operating temperature.  Moreover, the core  can easily be replaced by a core of different heat transfer ability without diminishing the ability to prevent such leakage.  To this end the core rests in the casing with the edges of one face engaged with a suitable ceramic fibre composition gasket;  the opposite face of the same flow path as engaged by another such gasket and the gasket is in turn engaged by a gasket compression member.  The compression member is urged into this engagement by strong springs which thereby hold the gasket in the necessary sealing engagement.  Preferably the body of the protective casing is of refractory material, and may be enclosed by a supplementary outer metal casing.  The exchanger may be used as a heat reclaimer receiving through one path the outlet flue gas of a high temperature furnace, and through the other path the combustion air for the furnace hot air burner.          Preferably the gasket compression member is located  at the inlet for the combustion air, which is the coolest location.  The invention also permits the production of an integral burner/ recuperator assembly without the need for heavily insulated connections as in the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE A fusible element for a current-limiting fuse comprises a metal ribbon having groups of holes therethrough and therealong. The distance along the ribbon between adjacent holes in a group is less than the distance along between adjacent groups. The lateral width of the ribbon between the hole groups is greater than its laterial width where the holes are located. The ribbon initially melts at the holes and multiple arcs burn back the ribbon at a first rate until the ribbon containing the holes is consumed, following which merger of the arcs occurs. This merger and the greater width of the ribbon between the groups results in burn-back of the ribbon at a second reduced rate. In this way, both 9 kv and 15 kv fault currents may be interrupted without exceeding the spark-over voltage of phase-to-ground arrestors when 9 kv fault currents are interrupted.
