Patent DE-3836157-A1 (DE)
IPC: F16L5/00
Filed: 1988-10-24
Abstract: The armature of a building inlet consists of a protective pipe (1) made of metal which is held in the building wall and of a metallic inner pipe (6), guided in the said protective pipe, having a terminal skirt-type piston (8). Connected to the free end of the inner pipe (6) is the underground medium pipe. The skirt-type piston (8) contains in the cylinder wall a transverse bore (9) which, in the starting position (open position) coincides with a wall bore (10) in the protective pipe (1), to which the building pipe can be connected. An outwardly projecting piston rod (13) with a marking (17) for position indication emerges from the head end of the skirt-type piston (8). In the event of a pulling or pushing action on the underground supply pipe, the inflow of medium is automatically cut off by displacement of the skirt-type piston (8). The particular operating condition of the armature can be detected from inside the building by visually checking the position of the piston rod (13). In the event of a response in which the medium has not yet been shut off, it is thus possible to introduce suitable countermeasures in good time. <IMAGE>

Patent DE-3843813-A1 (DE)
Title: Solutions of fluorine-containing polymers
Inventor: HARTWIMMER ROBERT DR
IPC: C08J5/22
Filed: 1988-12-24
Abstract: In mixtures of aprotic solvents, such as dimethylformamide and anhydrous carboxylic acids, fluorine-containing polymers containing -COOH groups dissolve without degradation if these groups are first converted into -COON(R)4 groups by reaction with tetraalkylammonium compounds. Such solutions can be used to produce cast films which, after reconversion into the -COOH form, are used as cation exchanger membranes. Films or coatings made from such solutions can also be used on greenhouse covers, where their hydrophilic surface allows condensation to run off more easily. Other applications relate to ion exchangers on supports and catalysts for chemical reactions.
Patent DE-3844398-A1 (DE)
Title: Control (controlled volume) pump
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F16H61/46
Filed: 1988-12-30
Abstract: The invention relates to a control pump having a flow (discharge, delivery) rate control valve which is controlled as a function of load (consumer) in order to match the flow rate to the load requirement. This purpose is served by a signalling line in which at least one control valve is arranged as a pilot valve for the flow rate control valve. If the permissible pump pressure exceeds a specific value set at the control valve, the drive pressure for the pump control valve is reduced and the flow rate of the pump is lowered to the required value without the delivery rate of the variable delivery (displacement, volume) pump being reset to zero, as is the case in the prior art when the pressure-limiting valve responds.

Title: Countercurrent-type broken-glass solar collector with bottom ray supply
Inventor: COST KARLFRIED
IPC: F24S10/80
Filed: 1989-03-23
Abstract: Technical problem and objective. Utilisation of solar energy for obtaining useful heat at a high temperature level using simple and inexpensive components. Solution to the technical problem. The novel feature consists in that the absorption in the covering layers and the heat transport by convection in the case of this design contribute to the effective output, instead of to a loss in output. The drawing shows the collector in cross-section, as well as the paths of the sucked-through air (broken lines) and the sun rays.     1. Collector wall, thermally insulated, airtight   2. Air extraction   3. Hollow space   4. Air-permeable layer with high flow resistance   5. Air-permeable glass fill   6. Wire grid   7. Path of the air (broken lines)   8. Path of the sun rays   9. Mirror   Convection losses are avoided by the countercurrent flow of the air. Energy losses due to heat conduction are avoided by the separation into a plurality of planes. Radiation losses are kept low by the large number of coverings. Energy losses due to absorption in the coverings are largely offset by the countercurrent flow of the air. Counter-radiation with inexpensive low-temperature heat improves the yield of high-temperature heat. Area of application. Use of highly heated air for a large number of technical processes. <IMAGE>
