Patent DE-3027592-A1 (DE)
Inventor: SCHNEIDER HARTMUT DR
IPC: C03B37/025
Filed: 1980-07-21
Abstract: Glass preforms useful for producing optical fibers therefrom are produced by forming at least one layer of glass on an inner surface of a hollow glass tube by introducing a reactive gas mixture suitable for glass synthesis (ie., SiCl4, GeCl4, etc., and O2) and a combustible heating gas mixture (ie., CO, C2N2, CS2, C4N2, COS, C3O2, etc., and O2) into a hot region within the hollow tube which is generated by exterior heating of such tube. The reactive gas undergoes a chemical reaction at such hot region whereby a material having the composition of glass is deposited on the hot inner surface of the tube as a layer and melts into a clear glass film while the heating gas combusts at the hot region and aids the rate of glass formation on the inner surface of the tube.

Title: Energy cell for generating heat for building heating
Inventor: MENGERINGHAUSEN MAX DIPL ING D
IPC: F24H9/06
Filed: 1981-01-24
Abstract: The invention relates to an energy cell for building heating, especially for the heating of residential buildings with few living units (single-family or two-family houses). It contains a plurality of heat generators (10, 11), heat accumulators (12) and/or heat exchangers (38), all to be operated by different kinds of energy, and associated conveying and regulating devices. There is a problem in that it is difficult for the heating installation companies at the place of use to assemble the multiplicity of components of such a system perfectly and economically, the different building plans and sizes also playing a part. As a result of the factory assembly of the numerous building components of such a system in terms of circuitry and space to form functional groups (1, 2, 3), and as a result of the spatially different positioning of these functional groups within a room cell (14) in dependence on the conditions prevailing at the place of use, there is provided an energy cell which can be connected to the building in a simple way and which solves the foregoing problem and can be built into or onto both new and old buildings. <IMAGE>

Patent DE-3118101-A1 (DE)
Title: Power/heat feedback
IPC: F01K17/00
Filed: 1981-04-16
Abstract: The invention relates to the field of energy conversion from primary energy (fossil-derived (atomic, solar) energy) into secondary energy (mechanical or electrical energy). The effect of the power/heat feedback is that in the case of the conversion of energy using turbines, internal-combustion engines or other expansion machines, the cooling energy is fed back with the aid of refrigerating machines or heat pumps (HP) into the primary circuit with the aim of improving efficiency. Exemplary embodiment 1 shows a HP (24) which extracts energy at the output of a turbine (22) (drives generator 23) and transforms it into the thermally operated boiler (21) (Figure 3). Exemplary embodiment 2 shows the indirect use of solar energy accompanied by the utilisation of temperature differences (Figure 5). Water from warm layers is led into cold layers after cooling by the turbine (22) and HP (24). In the case of too low a temperature at the turbine input, the turbine circuit is driven not by water but by a medium having a lower boiling point in the separate circuit. The exemplary embodiment 3 (similar to Figure 5) shows (32) a fossil-driven turbine which is supplied by means of a fuel pump (31).   <IMAGE>

Title: Transmission-shaft full-lining disc brake, in particular for heavy commercial vehicles
Inventor: KLAUE HERMANN DR ING
IPC: F16D55/10
Filed: 1981-07-18
Abstract: In contrast to spot-type disc brakes, which dissipate their braking heat predominantly by radiation, full-lining disc brakes with a revolving ribbed housing, which dissipate their heat by convection, that is to say operate in a relatively low temperature range, can be arranged to run opposite the wheel. The invention relates to a transmission-shaft full-lining disc brake of the said design which is accommodated in a casing. Baffles or channels in the casing ensure that air is fed to the brake at its inner circumference and carried out of the casing via an opening. By virtue of this measure, the brake can be of smaller and lighter design and is, in addition, protected against dirt from the road. Fig. 3 illustrates a brake according to the invention in longitudinal section. <IMAGE>
