Title: Reactivation of the dry chemisorption masses within the dry-to-wet process step
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/50
Filed: 1981-04-04
Abstract: In a process for removing sulphur dioxide and other pollutants from flue gases, a part-stream of the flue gas is subjected to a wet gas purification and the remaining part is subjected to a dry gas purification. Subsequently, the purified gas streams are recombined. The chemisorption agent which is used in the dry purification and is dosed in superstoichiometrically, for example hydrated lime, which has only partly reacted in the dry purification as a result of the high dosage, is then used in the wet gas purification. However, it has been shown that it reacts incompletely or only slowly in the wet purification. This is due to the sorbent having become hard and encrusted on the surface in the dry purification. In order to rectify this and achieve complete utilisation of the sorbent in the wet purification, the sorbent withdrawn from the dry purification is milled prior to its use in the wet purification, as a result of which new reactive surfaces are formed.

Title: Device for introducing a catheter
Inventor: SINNING KARL-HEINZ ING GRAD
IPC: A61M39/06
Filed: 1981-04-30
Abstract: In a device for introducing a catheter it is important that, when a catheter (14) is advanced, practically no forces are applied to the vein and the catheter (14) can be introduced quickly and safely into a blood vessel. To this end, the guide element (1) is designed as a hollow body whose cavity (4) widens in a funnel shape from an outlet opening (12) and is closed off by an end wall (8) lying opposite the outlet opening (12), in which end wall (8) there is an inlet opening (9) for a steel cannula (11) and, alongside this, at least one inlet opening (13) for a catheter (14). By means of this design of the guide element (1), before a blood vessel is punctured with the aid of the steel cannula (11) the catheter (14) extends axially and parallel to the steel cannula (11) and it retains this position of advance after the steel cannula (11) has been removed, so that it can immediately be advanced continuously and without any spring-back. The catheter (14) slides along the inclined plane formed by the wall of the funnel-shaped widened area (5) and passes automatically into the outlet opening (12) situated at the tip of the funnel-shaped widened area (5). With minimum force application, a long-stroke, sensitive advance is possible without the catheter (14) automatically sliding back. <IMAGE>

Patent DE-3140806-A1 (DE)
Title: Microprocessor-controlled ramp generator
Inventor: MERG BURKHARD DIPL ING
IPC: G01D9/10
Filed: 1981-10-14
Abstract: In many areas of technology, it is frequently necessary to record physical processes in time. This requires both the timescale (length unit per unit time) and the recording length to be influenced. The new microprocessor technology makes it possible for the first time to operate a ramp generator under program control with a corresponding input medium (for example keyboard) in such a manner that, for example in conjunction with a commercially available X/Y recorder, the user can achieve one or more recordings having the same or different timescales and recording lengths (started automatically or manually). In addition, control functions are possible such as the switching-on and -off of an object to be measured or pen-up and pen-down commands for X/Y recorders. This ramp generator opens a wide spectrum of applications to the user which extends from fast to very slow recordings of physical processes. An example of this is the starting-up and running-down of an asynchronous motor. <IMAGE>

Patent DE-3216909-A1 (DE)
Inventor: RUFRAY JEAN-CLAUDE
IPC: H04N9/68
Filed: 1982-05-06
Abstract: 1. Method for the limiting of the cathode-ray current in the picture tube of a colour television receiver, in which, for the automatic operating point adjustment of the video amplifier stages (1,4; 2,5; 3,6) for the colours red, green and blue with the aid of a control circuit (10) during a plurality of lines of the invisible part of the forward picture stroke, there are applied successively in time to the inputs of the video amplifier stages reference levels by means of switches (S17, S18, S19) which are successively closed by the control circuit, and during the application of the reference levels there is taken off a signal from which is produced for each video amplifier stage an amplification control signal which is effective for the duration of the visible forward picture stroke so that the amplification of the video amplifier stages is maintained at a constant value, in which for limiting the cathode-ray current a signal is derived from the average cathode-ray current of the picture tube, characterised in that the information (ABI) for the average cathode-ray current is compared in a differential amplifier stage (23) with a reference voltage (Vref ), and the output voltage of this differential amplifier stage (23), from a predetermined value onwards of the average cathode-ray current, which value exceeds the reference voltage, raises in such a way the current of a constant-current source (8) which produces the reference level to be introduced at a resistor (9) that the automatic amplification control actuated by the raised reference level decreases the overall amplification factors of the individual output amplifiers (1,4; 2,5; 3,6) in common in the same ratio.
Patent DE-3217302-A1 (DE)
Title: Glass fibre banding machine
Inventor: WINGERTER FRANZ
IPC: H01B13/08
Filed: 1982-05-05
Abstract: A glass fibre banding machine for winding glass fibre threads (7) around electrical conductors, having a rotatable head (1 to 5) which contains on its circumference a plurality of coils (11), supported such that they can rotate freely, of the glass fibre which is to be unwound. The conductors which are to be wound around are supplied through a central hole (9) in the head. In order to prevent a displacement of the wound-on glass fibre in the axial direction of the coils as a result of centrifugal force, the coil axes (14) are arranged tangentially with respect to the rotation direction of the head. Braking flaps (25) are pivoted against the coils, with the aid of springs (27), the spring force reducing as the pivoting increases, because of the reduction in the coil diameter. The compression force of the braking flaps is, however, kept constant by a corresponding increase in the centrifugal force acting on them which results from the fact that the axes (28) of the centres of gravity of the braking flaps are located outside their bearing axes (26). <IMAGE>

Patent DE-3235339-A1 (DE)
Title: Typewriter or similar office machine having a print head support carriage
Inventor: BEHRENDT WOLFGANG ING GRAD
IPC: B41J19/20
Filed: 1982-09-24
Abstract: In typewriters or similar office machines, it is necessary for at least the print head support including the adjusting means to be quickly exchangeable for the purposes of repair or for changing over from letter quality to highspeed printing with coarse-grained characters. The underlying object of the invention is to simplify the exchange of the print head support (1) in such a way that the latter can be carried out by the actual operator of the machine. This object is achieved in that the tensioned band (33) of a band mechanism has connecting means (51, 53) for a clearance-free plug-in connection (55, 57) to the slide (1) which is mounted so as to be displaceable along the recording medium. This quick-acting coupling is very user-friendly and can be carried out without special skill by the operator of the machine. <IMAGE>

Title: Process and apparatus for controlled cooling of a product
Inventor: CHRISTMAS MICHAEL JOHN
IPC: G05D23/19
Filed: 1982-10-18
Abstract: For the controlled cooling of samples which at least partially have a fluid form, in particular biological samples, it is of importance that the crystallisation takes place locally at the freezing point, without overcooling, and preferably with absorption of the latent fusion heat. A cooling device, which comprises at least one module (28a, 28b) which works according to the Peltier effect, the "cold" surfaces (36) of the modules being connected by a conducting metal strip (38, 40), keeps the sample container (24) in contact with the strip. The device is fixed in a working chamber which has a controlled temperature/time profile. At a temperature, which lies at a given amount above a predetermined critical temperature of the sample, for example the freezing point, the Peltier-effect modules are excited to the effect that they bring about additional cooling in a local region of the sample (24), for example at one end. <IMAGE>
