Title: Glazing block combination for windows and doors
Inventor: LAEKEN HERMANN
IPC: E06B3/54
Filed: 1983-09-19
Abstract: Glazing block combination comprising a putty bed inlay and a spacer block of differing thickness for the glazing of window and door sections, each comprising a part which can be fastened in the putty bed groove without the use of adhesive material and, at the same time, the spacer block can be positively coupled to the putty bed inlay. The self-clamping effect of the putty bed inlay is achieved by it being possible for the bearing surface of the putty bed inlay to be pushed by means of arrangement of an angle wall with the latter between window section wall and rubber gasket. Due to the type of fastening, it is possible not to take up the entire putty bed groove, since the fastening takes place on one side. The putty bed inlay is designed with clamping arms on its end faces, which arms make it possible to clamp firmly the spacer block subsequently to be pushed in between putty bed inlay and insulating glass pane. The spacer block is in turn designed with clamping studs which lie in a positive-locking manner under the surface and firmly clasp the clamping arms of the putty bed inlay. The spacer block is designed with notches taken out of the end faces and a gripping slot in the centre, which make it possible to exchange the spacer block more easily.

Title: High-attenuation band-stop filter
Inventor: SANDOZ JEAN-PAUL
IPC: H03H7/01
Filed: 1983-10-18
Abstract: The high-attenuation band-stop filter consists of a parallel resonant circuit (4), of a first supply circuit (5) for supplying a clock pulse signal into a transmission path at the input of the parallel resonant circuit (4), an amplitude/phase adjusting element (6) for producing a compensation signal at the same frequency as the clock pulse signal, and a second supply circuit (7) for supplying the compensation signal into the transmission path at the output of the parallel resonant circuit (4). The amplitude and the phase of the compensation signal are selected by the amplitude/phase adjusting element (6) such that the resultant voltage from the clock pulse signal and the compensation signal at the output of the parallel resonant circuit (4) is approximately equal to zero, so that the clock pulse signal is transmitted on the transmission path in only one direction. The first supply circuit (5) and the amplitude/phase adjusting element (6) are supplied from a common generator (3), and the transmission path is loaded at each of its two ends by a resistor R1 or R2 respectively. <IMAGE>

Title: Rotating mechanical seal with an elastomeric seal bellows
Inventor: ZECHMEISTER JOHANN
IPC: F16J15/36
Filed: 1983-10-19
Abstract: A rotating mechanical seal which is subjected from inside to the aggressive medium to be sealed off and in which the revolving slip ring (7) resting against a counter-ring (2) mounted in a fixed manner in the housing to be sealed off is connected via a polytetrafluoroethylene seal bellows (10) to a clamping ring (9) fixed on the shaft (1). The seal bellows (10), which is arranged radially within a spring arrangement (13) for the axial preloading of the slip ring (7) and a torque transmission arrangement (12) and protects these components from the aggressive medium, has a first connection part (15) with a portion (18) which rests against the shaft (1), at the outside widens conically towards the centre of the bellows and is surrounded and subjected to pressure externally by the clamping ring (9), which is of complementary shape. The thickened second connection part (16), which is likewise integrally moulded on the seal bellows (10) projects with an outer, tapered connection face into a tapered surface of complementary design in a bore of the slip ring, is reduced in thickness at the free end to form a lip and is provided in the tapered connection surface with encircling grooves (25). By virtue of this design, leaks at the transition to the slip ring caused by cold flow of the bellows material and the necessity for an adjusting ring to be placed behind the clamping ring are avoided. <IMAGE>

Title: Process and apparatus for heat generation
Inventor: LUEBKING JUERGEN
IPC: F24H1/20
Filed: 1983-11-04
Abstract: The efficiency in a process for the generation of heat, especially for the conversion of electrical energy into heat energy, with media of different temperatures flowing past each other in a heat exchanger on the counter-flow principle, can be improved if, of at least two streams of media, that with the higher temperature flows in a closed circulation and is interleaved with an outwardly open stream of medium of low temperature such that the stream of medium of low temperature is enclosed multiple times from two sides by that of higher temperature. Especially suitable for this is a heat exchanger with an outer container, open on one side, and with at least two containers of similar shape inserted therein, spaced from the container floor, mutually interleaved and of which the inner container is heated.
Patent DE-3342534-A1 (DE)
Title: Electromechanical blood pump drive
Inventor: STEINER HELMUT LUDWIG
IPC: A61M60/459
Filed: 1983-11-22
Abstract: An electromechanical drive designed as a stepping motor actuates membranes of blood pumps via pressure plates, so that the pumping function of the heart can be supported or substituted. The electric motor thereby resembles an "electromechanical digital/analogue converter" in that it transforms a binary input signal into a linear movement of pressure plates. At the same time, the stepping effect is obtained due to the sequential excitation of different windings. When designed as a miniaturised linear or rotational motor the drive can also be used intracorporeally. The exact positioning of the pressure plates permits exact tuning of the stroke volume of the artificial blood pump and hence a delivery behaviour of the technical pumping system adapted to the physiological requirements of the body. The variable necessary for adjustment is, on the one hand, obtained from the load angle on the drive side and, on the other hand, derived from the nerves and fed to the driving processor via a controlling and computing program implemented in the master computer. In the embodiment as a rotational stepping motor a rolling body spindle generates the desired linear movement of the blood sac pressure plates. The blood pump drive largely saves blood due to its pusher plate mechanism.

Title: Process and apparatus for adsorptive separation of xenon and krypton from a gas mixture which, in addition to xenon and krypton, in particular contains nitrogen and oxygen
Inventor: RINGEL HELMUT DIPL ING DR
IPC: C01B23/00
Filed: 1984-08-13
Abstract: For the purpose of adsorptive separation of xenon and krypton from a gas mixture which essentially contains proportions of air, German Laid Open Specification 3418972.6 describes a process having two adsorption sections. Starting from this process, provision is made, when adsorbing, to adsorb even xenon in the first adsorption section over part of the length only, so that during desorption xenon can be drawn off in isolation. The adsorbant of the first adsorption section, in doing so, is cooled to a temperature of not lower than -130 DEG C, the adsorbant of the second adsorption section to a temperature in the temperature range between -150 and -180 DEG C. For the purpose of desorption, both adsorption sections are heated stepwise while supplying the flushing agent, a temperature step initially being set, while still below room temperature, at which the air proportions and krypton flow off separately from the gas outlet of the second adsorption section. After breakthrough of krypton at the outlet of the second adsorption section, further heating of the adsorption sections above room temperature is carried to out to desorb xenon.
