Title: Regeneration of fine residues from gas purificn. - by fragmentation and return to reactor transported by hot gases
Inventor: HUENLICH HANS-WERNER DIPL ING
IPC: B01D53/34
Filed: 1979-03-17
Abstract: After passing from the reactor of a used gas purificn. plant, possibly through an intermediate receiver, dry and finely granulated residues, are fed directly into a machine in which they are fragmented in the presence of a current of gas moving at a speed of at least 2 m/s. They are then directly re-introduced into the reaction system. For pref. the gas extracting the residues from the fragmentation plant is formed in part by a flow of used gas which is to be purified, and is at a temp. higher than 80 degrees C. The gas extracting the fragmented residues may be superheated steam or it may be a mixt. of used gas to be purified and steam. Used for the regeneration of dry and finely divided residues from an installation for the purificn. of used gases contg. non-atmospheric and esp. acidic substances. A more efficient system of fractionating the residues is proposed so that extra fine particles with large new surface areas are produced.

Title: Chlorine purificn. by compression. liquefaction and re-vaporisation - using inert heat exchange medium, pref. hexa:chlorobutadiene to prevent corrosion
Inventor: PAYER STEFAN DIPL CHEM
IPC: F25J3/00
Filed: 1979-06-30
Abstract: In the purificn. of chlorine gas by compression, liquefaction and revaporisation, the heat of compression and liquefaction is transferred to a heat carrier (I), which is inert towards chlorine, and the heated (I) is used for revaporisation and superheating of the liquefied purified chlorine. (I) is hexachlorobutadiene. Pt. of the heated (I) can be used for heating a stream of raw material. Since (I) is used instead of water, there is no danger of corrosion of steel heat exchangers by chlorine gas leaking into the water side. Also, the use of steam for heating is avoided.

IPC: G01R19/165
Filed: 1979-09-03
Abstract: A voltage monitoring circuit for devices with several operating voltages checks all operating voltage sources within a system w.r.t. tolerance limits. An accurate reference voltage (UREF) source (1) is connected to all the monitored voltages (-U,+U) at a common point, pref. the circuit earth. A potential divider (2) contg. several ohmic resistances (R5,R6,R7..Rn) divides the reference voltage (UREF) to give the tolerance field desired values (S). Individual potential dividers each contg. two ohmic resistors (R1,R2;R3,R4) extract fractions (-u',+u') of the operating voltages. These are input with corresp. single outputs from the multiple divider (2) into an evaluation circuit (5). The evaluation circuit contains operational amplifiers evaluating the ratios of actual values to corresp. desired values. The amplifiers drive warning devices, pref. optical, associated with each operating voltage source. Signal lamp or light emitting diode indicators may be used.

Title: Heat exchanger esp. steam generator for gas cooled reactor - has helical tube bundle in annular space with central steam outlet duct
Inventor: BAUMGAERTNER HEINRICH
IPC: F22B1/18
Filed: 1980-04-01
Abstract: A heat exchanger for a gaseous prim. medium of a nuclear power plant (typically helium) and a sec. medium (water steam) has a helical tube bundle inside a liner void (pod) in a reactor pressure vessel; the hot gas inlet and cooled gas outlet ducts are horizontal while the outlet pipe for the steam is central and vertical. The helical bundle is fixed to its inner casing and the top end of this casing is welded to a flange of a support pipe, which in turn is suspended by a further flange, from the top cover of the pod. The support pipe continues up through this cover.S The steam discharge duct is divided into two separate parts the lower part is also suspended from the same flange as the tube bundle inner casing, while the upper part is composed of a length mounted concentrically inside a pipe, these two pipes being connected together at their lower ends by a thermosleeve these two concentric pipes in turn are housed inside the support pipe and coaxial with it, thus forming a closed annular chamber inside the support pipe and outside the outer of the two concentric pipes. The sec. medium (water) inlet duct leads into this annular space, which thus acts as the inlet header to the boiler unit consisting of the helical tubes. Radial connecting pipes lead from this header to the helical tubes. At the bottom of the boiler unit, radial pipes connect the outlet from the helical tube bundle to the central pipe which acts as the outlet header for the boiler. Used esp. for a helium-cooled, high-temp. reactor. The arrangement enables the temp. strains in the barrier components between the prim. and sec. circuits to be kept to a min. and permits a simple layout of the sec. circuit.

Title: Safety catch for trailer coupling - has pivoted release lever with sprung axial action
Inventor: CRAMER GEORG
IPC: B60D1/02
Filed: 1980-04-26
Abstract: The safety catch for a trailer coupling has the drawbar coupling eye retained by a spring loaded bolt (2) lifted by a clawed end (4) of the release lever (3). The release lever has a second claw (14) which is held in the down position by a safety bolt to prevent the coupling from opening.

The single lever action enables a single handed operation, to allow the operator to guide the drawbar with the other hand. The claw is held in the open position by a spring loaded trip lever (5) whose end (16) grips a cam surface (17) under the claw. As the drawbar is inserted the trip operates and releases the locking claw.
