Title: Process for the unpressurised preparation of alpha-gypsum hemihydrate and equipment for carrying out the process
Inventor: QUANTE HEINRICH
IPC: C04B11/02
Filed: 1985-06-24
Abstract: In the unpressurised preparation of alpha-gypsum hemihydrate from flue gas desulphurisation gypsum or chemical gypsum, the dihydrate is first brought into a fine granular form, then mixed with sulphuric acid, heated to approximately 100 DEG C, namely by direct or indirect supply of especially industrial waste heat, then separated off and finally dried. This process is controlled via controlling the parameters of heat supply, sulphuric acid concentration and/or quantity of dihydrate and/or Fe2O3 content. The process parameters required for evaluating the process, such as quantity of water of crystallisation, crystal size and crystal form of the hemihydrate, anhydrite content, length of the induction phase and reaction phase are regularly monitored. For carrying out the process, equipment is used in which the reactor or reaction channel is designed as a plug flow reactor. For monitoring and controlling the process, oil or paraffins are preferably added in a quantity of 0.1 to 2 % by weight, relative to the gypsum (dried), as additional regenerators. Sulphur oxide as a washing agent and flocculants in the form of polyacrylamides or potassium ions or sodium ions, which all together exert an advantageous influence on the crystal growth, serve as further regenerators. <IMAGE>

Title: Adder circuit in 51111 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1986-07-05
Abstract: The adder circuit according to the subject of the invention has a main circuit which consists only of nine individual adder circuits (5). The way this reduction in the number of required individual adder circuits is made possible is that these individual adder circuits (5) process the value 2, and that a partial summand with the value 5 is derived from all summands which are greater than the number 4. This adder circuit thus has a dual full adder to process the value 5, and a dual full adder to process the value 1. <IMAGE>

Title: Axially shortenable winding core
Inventor: BECKER JOSEF
IPC: B65D59/04
Filed: 1986-08-22

Patent DE-3635819-A1 (DE)
Title: Process for the production of a low-loss optical waveguide
Inventor: SIEFERT WOLFGANG DR
IPC: C03B37/027
Filed: 1986-10-22
Abstract: Optical waveguides are produced by collapsing internally coated glass tubes to give a solid preform, which is then drawn out. In order to increase the refractive index, either a dope, usually germanium dioxide, can be added to the core or the core can comprise pure SiO2, the regions away from the core containing, for example, fluorine in order to reduce the refractive index. However, evaporation of germanium dioxide during the collapsing impairs the transmission properties of the finished optical waveguide, and optical waveguides produced hitherto having a core of pure SiO2 have higher losses than theoretically expected. The novel process is intended to give optical waveguides of better quality with a pure SiO2 core. A low-loss optical waveguide having an increased transmission band width and low flexural losses with a pure SiO2 core can be produced simply by setting an oxygen pressure of p < 10 mbar inside the glass tube during the collapsing or drawing of the glass tube. Production of an optical waveguide.

Title: Hermetically sealed optical fibre bushing
Inventor: ROSSBERG ROLF DIPL PHYS
IPC: G02B6/44
Filed: 1986-11-12
Abstract: In order to avoid metallisation of the bare optical fibre (7) which has been required hitherto before the soldering of the optical fibre (7) into a metal sleeve (3) of the optical fibre bushing (1), the wall of the receptacle bore (6) in the metal sleeve (3) is provided over part of its length with a non-solderable coating. The said coating can be a solder resist or consist of an oxidised wall surface. A further solution provides for a recess which partially exposes the receptacle bore (6) of the metal sleeve (3) and can be constructed for example as a slot or as a cut-out which reduces the cross-section of the metal sleeve (3). Both solutions cause the solder (11) to shrink tightly onto the bare optical fibre (7) as it hardens. The junction of this part of the soldered joint with the other part in which the wall of the bore is wetted with solder (11) forms the hermetic seal. <IMAGE>

Abstract: Signalling headlamps on radiators and car roofs, mounted in a housing which has two curved protective glass elements with three different coloured windows which are green, red and colourless, among which it pivots between two rubber supports in a rectangular pipe on a shaft 8 as a result of movements of the vehicle, as a result of which the said headlight indicates any change in speed of the car precisely and with a change in the colour of its light and in the case of a strong respective change pivots on one of the rubber elements and as a result trembles together with the light source and the clearly visible illuminated headlight pattern to such a degree that ... from the latter by the light being reflected from the curved protective glass elements is produced ... from two metal mirrored walls of the housing. One of two rubber bands pulls the headlamp back again to a straight position in the centre of the housing when the vehicle is at constant speed, where these bands allow it to tremble approximately at red until the speed of the car changes again or the car comes to a stop and as a result the headlamp also comes to rest; during pivoting, headlamp does not tremble, on the other hand. For the headlamp on the radiator, the light colours of the ... on the roof of the car travelling ahead can easily be changed in colour by identical speed, as a result of which this speed can be observed satisfactorily. The housing over the radiator can be locked and unlocked with two rectangular tubes by means of a lock and mechanical accessories and as a result lifted off over the headlamp, by contrast the headlamp can be moved downwards into the car by means of two round rods, in which case ...
