Title: Industrial steam generation by spraying water onto evaporator - evaporator consists of coiled pipe mounted in disc shaped housing for simplified process
Inventor: PILZ FRANZ
IPC: F22B27/16
Filed: 1975-07-14
Abstract: The water is atomised by compressed air into sprays jets consisting of fine droplets, which are sprayed onto an evaporator. The latter consists of a coiled pipe mounted in a disc-like housing formed by oval curved side walls to provide an elliptical cross-section. The water droplets evaporate on the evaporator surface, and the resulting steam-air mixture is removed from the evaporator housing. Several jets may be sprayed onto the evaporator surface from different directions: e.g. two spray jets are directed through diametrically opposed inlet openings (45) in the evaporator housing onto both sides of the evaporator which is located in the longitudinal plane of its housing.

Title: Heat exchanger alternately heated and cooled - is arranged for cooling pump to assist main pump at intervals
Inventor: SCHAEFER OTMAR DIPL ING
IPC: B30B15/34
Filed: 1975-10-29
Abstract: A press (3) which is alternately heated and cooled is connected to a calorifier vessel (1) through a three way valve (4). While the main pump (2) circulates hot water through it, the cooling pump (7) circulates chilled water between a storage vessel (5) and a cooler (6). When cooling starts the three ways valve (4) changes so that the main pump (2) circulates chilled water from the storage vessel (5) through the press. A parallel flow is maintained through the chiller (6). As soon as a preset temperature is reached bypass control valves (8, 10) operate so that the flow through the press goes through both pumps (2, 7) in series. This increases the throughput and thus increases the rate f response of the system.

IPC: C07C255/49
Filed: 1975-11-08
Abstract: In the prodn. of trifluoromethyl-substd. benzonitriles of formula (I), trifluoromethyl-substd. benzotrichlorides of formula (II) are reacted with 4 molar proportions of ammonia (the ammonia being present in excess throughout the reaction) or with NH4Cl in the presence of metal salts at ca 150-250 degrees C, opt. in the presence of a solvent and/or diluent. In formulae (I) and (II), R1 is H, halogen, or opt. substd. alkyl, aryl or alkoxy; and R2 is H, halogen, CN, NO2 or CF3. (I) are intermediates for dyes (DT 2364475), pharmaceuticals (DS 1280878; US 3133081) and plant protection agents (DT 1009497). (I) are obtd. in high yields. It is surprising that the CF3 group is not converted into CN under the reaction conditions. In an example, 2-chloro-3-trifluoromethyl-benzonitrile is obtd. in 83% yield by heating 470 g 2-chloro-3-trichloromethyl-benzotrifluoride 5 hrs. at 220 degrees with 1 g FeCl3 and 109g NH4Cl.

Patent DE-2605413-A1 (DE)
Title: Rectilinear reciprocating feed mechanism - has double valve crank and valve controlled pneumatic cylinder as overload safety device
Inventor: GROT UWE
IPC: F16P7/00
Filed: 1976-02-12
Abstract: The cranks are connected by a push rod operating them by an intermediary of cylinder housing. The push rod carries a piston which operates in the space of the cylinder. The push rod penetrates the far end of the cylinder and terminates in a protruding pointed end. During normal operation the pointed end, while moving along a circular paths misses the roller fitted to the stem of the switch. When, the crank is restrained by some obstacle in its movement. The push rod continues its travel against a certain pressure in the space. The pointed end protrudes more from the cylinder face than it did before and it contacts roller thereby operating the switch. It operates a control circuit so that the space is relieved of pressure and remains so, in order to allow unhindered rotation of crank.

Title: Thermal regeneration of active carbon or coke - from sulphur dioxide adsorption plants, e.g. in power stations
Inventor: NOACK ROLF DR ING
IPC: C01B31/08
Filed: 1976-03-11
Abstract: In a process for regenerating SO2-laden active carbon or coke, part of the stream of desorbed gas is introduced into the regenerator below the hot active carbon/coke zone and removed at a higher level in a preheated condition. The gas is then further heated in an external gas heater and returned to the regenerator. The active carbon/coke migrates downwards through the regenerator. The process removes all of the heat from the outflowing materials except the heat remaining in the desorbed gas passing to a further process (e.g. sulphur recovery and that in the active carbon) coke, which can be recovered using cooling water. Used in desulphurisation of process gases, esp. flue gases from power stations.

IPC: F23K5/02
Filed: 1976-04-13
Abstract: A system for combustion of a liquid fuel or a fuel mixture by means of an atomisation process using a burner constructed to atomise fuel during its operation. The liquid fuel or fuel mixture is pre-heated and divided into twin flows, the part of the fuel vaporised by pre-heating being fed under almost constant pressure conditions, in a flow against the film formed by the other, non-vaporised part of the fuel to produce simultaneous vaporisation of that part of the fuel flow.
Patent DE-2619261-A1 (DE)
Inventor: JORDAN ERNST
IPC: B23H7/10
Filed: 1976-04-30
Abstract: In an electrical discharge wire cutting machine, the wire electrode is drawn off from a supply spool, passes the workpiece to be machined and is taken hold of behind the workpiece by a gripping device and moved to the deposit side. A threading device serves to automatically thread the wire electrode into the bore in the workpiece. The basic idea behind the invention is to show an especially advantageous threading device which consists only of a cutting device and a feed device. When a push bar (20) actuated by a rotary magnet (24) is fed into the working position, first of all the wire electrode (8) is clamped in place by two feed rollers and is then cut off. During further advance of the feed bar, the wire electrode is released again by the wire-cutting device. By opposite driving of the feed rollers, the wire electrode is transported further until it is taken hold of by the gripping device on the deposit side of the electrode. <IMAGE>

Title: Plant pots made of compressed fibrous material - with stable dimensions and sufficient stretch for automatic filling
Inventor: MELVOLD ODD
IPC: D21J5/00
Filed: 1976-11-19
Abstract: Method for mfr. of plant pots of fibrous material is carried out by drying them to a moisture content of  20%, then compressing them at a pressure of >=50 kg/cm2. Pref. the edge zone of the pot is compressed in the axial direction of the pot in such a way that it expands when water is added, providing a thickened edge in the region of the opening of the pot. The resulting stable dimensions of the pot allows them to be handled by automatic machines. On compression, the pots acquire a wall thickness of e.g. 0.6 mm which saves space by 30-40% when stacking. The pots can absorb water more rapidly, and when filled to the brim with earth in the dry state, the edge expands upwards, reducing the risk of soiling from splashing water mixed with earth.

IPC: A63F3/02
Filed: 1977-01-25
Abstract: A game similar to chess but intended for three players is played on a triangular board divided into 81 hexagons. Each player has nine pieces comprising one king, one queen, one rook, one knight, one bishop and four pawns. The pieces of each player are grouped in the hexagons at each corner of the board. The moves of the pieces are similar to those of standard chess. The king moves one hexagon in any direction. The knight jumps over two adjoining hexagons and finishes in any one of twelve possible hexagons. The rook moves in a straight line into and across adjoining hexagons. The bishop moves along the boundary of adjoining hexagons into any hexagon aligned with the corners of the starting hexagon. The queen combines the moves of rook and bishop.
