Title: Sepg. sulphur di:oxide from carbon di:oxide and water vapour mixt. - obtd. from desulphurising plant, used to remove sulphur from combustion fumes
Inventor: LINDE GERHARD DR
IPC: C01B17/60
Filed: 1980-01-25
Abstract: To recover SO2 from a raw mixt. with CO2 and water vapour etc., in a first stage the mixt. is cooled in one of a set of three cyclically operating regenerators filled with coke or graphite to condense the water, and is then compressed and fed to an adsorber and a rectifying column from whose base SO2 is taken in liq. form. In a second stage each regenerator is flushed with gas from the rectifying column to remove residual SO2 which is returned to the hot end of that regenerator then in the first raw gas treatment stage. In a third stage the rectifying column is flushed by rectifying gas, with atmospheric air added to correct the thermal balance but cut off near the end of this third stage. HF present in the mixt. is reacted with CaCl2. Used for the mixt. obtd. when S is removed from combustion fumes by adsorption in active coke and the coke is then desorbed. The sulphur is here required as SO2 and not the more usual elemental S.

Patent DE-3008942-A1 (DE)
Title: Fluidised catalytic cracking reactor - where cyclone dip-legs extend from reactor vessel into stripping vessel through vent lines
Inventor: JAHNKE FREDERICK CHARLES
IPC: B01J8/28
Filed: 1980-03-08
Abstract: A fluidized catalytic cracking unit has a vertical cylindrical reactor vessel for maintaining a dilute phase of catalyst suspended in hydrocarbon vapour above a fluidized dense phase bed of spent catalyst. A cylindrical stripping vessel is vertically positioned below the reactor. A spent catalyst collector communicates with the reactor interior through its bottom to provide a static head of catalyst which will exceed the pressure differential between the reactor vessel and the stripping vessel. A spent catalyst transfer arrangement is in communication with the lower interior of the spent catalyst collector and with the stripping vessel interior for transferring catalyst from the reactor bottom into the stripping vessel. Stripper vent lines communicate between the top of the stripping vessel and the upper portion of the reactor to allow stripping vapours from the stripping vessel to the dilute phase region of the reactor. Cyclone separator catalyst diplegs extend from cyclone separators in the reactor, through the stripper vent lines into the stripping vessel. They provide a path for separated catalyst from the cyclone separator into the stripping vessel. A column of catalyst is maintained in the diplegs to prevent blow-by of either hydrocarbon vapours from the cyclone separator or stripping vapours from the stripping vessel through the legs. The invention reduces the required regenerator vessel height. This results in a redn. in the cost of such a cracking unit. Also, the depth of dense phase catalyst bed in the reactor vessel may be reduced to the minimum required to properly seal the reactor vessel slide valve. This eliminates overcracking of hydrocarbons in the dense phase bed.

Patent DE-3021353-A1 (DE)
Title: Circulating clarified water in sulphur removal process for fumes - from steam boiler fired by oil or coal
Inventor: GEBHARD GEORG DR ING
IPC: B01D53/50
Filed: 1980-06-06
Abstract: After treatment by an electrostatic filter the fumes from coal- or oil-fired steam boilers pass for sulphur removal to a wet treatment stage using calcium-based absorption media, which when charged with sulphur cpds are thickened. The resulting gypsum suspension has water removed and goes to a centrifuge for further processing. The centrifugate is fed to the thickener unit, from which water is withdrawn and clarified. Part of this clarified water is returned to the original wet fume- treatment stage, and the clarification slurry is partly dried and then mixed with additives combining with harmful materials. Clarification of the circulating water prevents build-up of harmful materials such as heavy metals, which makes the gypsum crystals purer and easier to obtain. The clarified water can replace fesh water, e.g. for cleaning the wet treatment units.
Patent DE-3028162-A1 (DE)
Title: Casting mould for plastics has cylindrical core - disengaged from moulding by short separating stroke and admission of air into mould through valved duct
Inventor: HANISCH BERTHOLD DIPL ING DR
IPC: B29C45/40
Filed: 1980-07-25
Abstract: A casting mould for producing cylindrical plastics mouldings, esp. having a conical, cylindrical or star-shaped bore, consists of a divided mould (1,4), with the mould core (2) fixed in one half-mould (1). To loosen the moulding (5) from the core (2), a stop pin (6) or a stripper fork (7) is located adjacent to the edge of the moulding; to activate this stop pin or stripper fork, a lever (8) is operated, the effect of which is to move the mould insert (3) relative to the half-mould (1) and consequently to displace the mould core (2) relative to the moulding. A short stroke movement is produced in this way. A central pin in the core can be retracted, permitting air to enter the mould and thus also facilitating removal of the moulding. Plastics mouldings with internal, absolutely cylindrical bores can be produced and easily removed from the mould.
Patent DE-3040333-A1 (DE)
Title: Machine for cutting circular plates - has two rotating circular cutters with upper cutter mounted forward of lower cutter
Inventor: ARNALDO TISATO
IPC: B23D35/00
Filed: 1980-10-25
Abstract: Circular plates are cut from square metal sheets by machines with rotating circular blades mounted one above the other. The axes of these blades are usually arranged so that they lie in a common vertical plane. A cleaner cut edge is produced if the upper blade (2) is moved forward of the lower blade (5). This forward movement is achieved by mounting the housing of the shaft driving the upper blade on a pivot so that it can swing through a limited angle in the horizontal plane. The housing movement is controlled by an eccentric cam so that the amount of offset can be varied as required. This arrangement of blades also reduces the risk of accident to the operator as it is less likely to pull the workpiece through the blades before the operator has released his grip.

Title: PCB with inclined clearance holes - prevents through-connection wires sliding axially during soldering operation
Inventor: HOEH CLAUS-ARNO
IPC: H05K3/34
Filed: 1980-11-06
Abstract: The circuit board (1) has holes (2) sloping through it from one side to the other and carrying connection wires from components on one side of the board. The angle of inclination of the clearance holes is such that the force component acting on the wire during soldering in a direction perpendicular to the circuit board is large enough to produce a turning moment that prevents the wire sliding in the hole. The friction between wire and hole is also appropriately large to assist in preventing sliding. The through-holes may be a normal hole passing at an angle through the board or it may be an elongated hole or slot in which the wire is placed at an angle.

Title: IC engine fuel injection system - has high and low pressure stores, controlled valve, buffer and throttles to increase flow at each injection
Inventor: MIKOTA THOMAS DIPL ING
IPC: F02M47/04
Filed: 1980-11-25
Abstract: The ic engine fuel injection system comprises a pump-fed high constant-pressure fuel storage unit connecting to the fuel chambers at the injector needle seats via synchronously controlled valves with downstream pressure relief lines containing throttles orifices. All lines lead to a low constant-pressure store with a fuel return line, and the chambers connect to a buffer chamber. Each fuel line contains a throttle upstream of the valve. The two throttles are such that, during each injection, the pressure increases from the low to the high storage pressure and, during each interval, again drops to the low pressure, so that the amount injected per unit time gradually increases during each injection.
Patent DE-3046983-A1 (DE)
Title: Circuit for telephone exchange with controllable group selectors - can seize any selector via at least two inputs and sub-divides output groups
Inventor: SEDLMAYR OTTO
IPC: H04Q3/06
Filed: 1980-12-12
Abstract: The local exchange (V1) besides having subscriber locations (T1,T2,etc.) has uniselectors (A5), group selectors (IGW,IIGW, GW and nGW) as well as line selectors (LW1,LW2) constructed in the customary way. The selectors work with their own control and are arranged in sequential selector stages. In each group selector stage, a newly engaged group selector receives information in the shape of a decade figures (pulse series of 1 to 10) by which the group selector is controlled to one of its output groups to search for a free output and occupy it. The advantage is that the group selector can be engaged via at least two inputs, and dependent on a resultant occupation, is switchable via one or other inputs selectively, to one of at least two monitoring circuit channels. Also, at least one of the output groups is divided up into sub-groups of outputs.
