Title: Purified air feed esp. into automobile - heats air before filter to improve sorption and catalytic effects
Inventor: HOELTER HEINZ ING GRAD
IPC: B60H3/06
Filed: 1980-02-08
Abstract: A method of purifying air to be fed into a protected working zone or automobile cabin utilizes a filter consisting of a permeable support on/in which chemical absorption materials and/or catalysts are laid. The incoming air is entirely or partly heated before it reaches the filters. When the appts. is in use, the normal fresh air inlet ducts of an automobile are closed and the ventilator fan is converted for use as a pure circulating fan recycling the entire air content of the vehicle. In addn., a separate ventilator fan draws in air and expels it at above-atmospheric pressure into the circuit via the chemical absorption filter. A corresponding quantity of air escapes from the circuit to atmosphere. In particular for automobiles in traffic jams or smog conditions as a substitute for conventional ventilation. By heating the air before it reaches the chemical absorption filter, moisture in the air is prevented from precipitating. Precipitation of moisture has a very adverse effect upon the effect of chemical absorption agents and catalysts. Thus the efficiency of the plant is greatly improved.

Title: Shut-off valve for high pressures
Inventor: BERGMANN WERNER DIPL ING
IPC: B05B9/01
Filed: 1981-03-14
Abstract: The invention relates to a shut-off valve for high pressures, in particular for high-pressure spray guns. The known solutions still have certain deficiencies: either there is a need for closing springs, which in the case of certain proposed solutions are surrounded by the liquid and corrode, or there is a need for bypass passages, which increase the production costs, or there is an excessive number of sealing elements, which have a negative effect on reliability of operation. The aim of the invention is a very simple solution which does not have these deficiencies and can be operated with little expenditure of force. According to the invention, this is achieved by virtue of the fact that a hollow cylindrical control piston is mounted with a defined clearance in a housing and this piston has a sealing seat on the inside and a valve cone on the outside. Mounted in the control piston is a valve body, the tappet of which is passed through to the outside and can be moved counter to the prevailing pressure by means of the operating lever. The shut-off valve has only a small number of components.
