Title: Unregistered fancy textile printing process
Inventor: ERICH FEESS DR
IPC: D06P5/12
Filed: 1969-06-10
Abstract: Fancy textile prints of batik-type patterns on cellulosic fibres (without register alignment) are produced by treating the goods with alkali and drying. They are then printed with one or more colours, each of which contains alkali-absorbing resist material, a reactive dye which can be fixed by a tow-phase a cold-delay or a two-phase quick-fixation process, and a reactive dye which does not respond to these processes. Alternatively, the patterns are produced by treating the goods with a relatively insol. alkali-absorbing resist material and drying. They are then printed with one or more colours, each of which contains alkali and mixtures of dyestuffs of the two types referred to above. The goods in each case are dried and the dyes fixed by steaming in combination with one of the two-phase processes mentioned above.

Title: Chemical respirator warning system - has light-signal indicating fall of sorbent's electrical resistance
Inventor: WALLACE RICHARD A
IPC: A62B18/08
Filed: 1973-07-14
Abstract: Safety warning system for a chemical respirator which has a chemical sorption medium in a sleeve attachable to the user's body, for passage through of gas produced in the sleeve, which is connected via channels to the face-mask. Opposed electrodes are in contact with the sorbents in the sleeve, one reaching only into the upper region of the sorbent, so that a high resistance exists between the electrodes. A signal unit is in series with the electrodes and a direct current supply source. A large fall of the resistance of the sorbent is used to give a light signal which indicates the remaining useful life of the sorbent. Preferably the source is a battery.

Title: Ozonise with tubular gas discharge chamber - cooled by evaporating coolant at low flow speed which avoids turbulence
IPC: C01B13/11
Filed: 1973-10-30
Abstract: An ozonisator comprises a tubular housing of insulating material having a metal coating on its external face and constituting the discharge chamber; through this a hollow electrode passes coaxially, so that gas discharge takes place between the metal coating and this hollow electrode; the chamber surrounding the discharge vessel and the internal chamber of the hollow electrode act as evaporator spaces for a coolant, which cools the walls of the discharge chamber by the heat required to evaporate it. The air supplied to the ozonisator pref. first passes through a condensation chamber to dry it; in particular this may be cooled to just above O degrees C, this chamber being followed by a chamber considerably below O degrees C for freezing out the liq. Since the appts. operates with relatively slow coolant speeds, turbulence does not occur, which could lead to risk of warm spots.
