Abstract: Living plants, in particular coniferous plants, with the exception of Picea, Abies, Tsuga; Larix, Taxus and Cedrus genuses, are preserved in that they are caused to suck up a preservative liquid which is based on glycerine and water in the tolume proportions of 18:82 to 35:65 and contains dyestuffs for replacing the color of the plant parts after the preservation. The dyestuffs are to comprise, apart from a blue and possibly also a red dyestuff, tartrazine (C.I. 19140, E102) in a concentration of from 2-10 g/I of preservative liquid. The blue dyestuff comprises preferably patent blue V (C.I. 42051, E131) in a concentration of from 0.1 to 0.8 g/I and the red dyestuff most preferably of new coccine (C.I. 16255, E124) in a concentration of from 1 to 20 g/I. The relative concentrations between the different dyestuffs are adapted into conformity with the sought-for color of the preserved plant. The preservative liquid may advantageously also contain at least one plant nutrient substance, in particular a water-soluble potassium salt, preferably potassium nitrate in a concentration of from 1 to 15 g/I. The preservation is effected at a temperature of from 15 to 33° C in a current of air at a relative humidity of at most 60%, the preservative liquid preferably being a few degrees centigrade warmer than the current of air. It is advantageous to add, to the preservative solution, an amphoteric sulphonated surface active agent in an amount of from 0.2 to 1.5 vol.-% in order to attain a shaded coloring of young and old shoots. It is also advantageous to adapt the pH and conductivity of the preservative solution to the analysed pH and conductivity Of the plant stock subjected to preservation.

Abstract: This window frame allows the complete closing or opening of the window-space by means of a single upright-sliding shutter disappearing entirely into the wall, when it is completely lifted. 
     If it contains more shutters, each of them carries on a specific function of its own and by itself, that is the function of a windowpane or a blind or a house-breaking proof closing device. 
     It allows an high degree of thermal insulation of the room both because it is lacking in all those slits through which air filters in common roller shutters, and because the shuter 5 can be high termal insulating. 
     The shutters can be supplied with a locking device which be inaccessible and off sight in order to prevent them from being lifted from the outside, even when they are partly lifted in an opening position.

Abstract: An electronic control fuel injection system for a spark ignition internal combustion engine (12) is described wherein: a signal corresponding to the stroke imported to an accelerator pedal (28) by an operator is supplied to a computer (20) where, in a shaping section (32), a corresponding fuel demand signal is derived in accordance with a selected one (A, B or C) of a plurality of functions each specifying a respective predetermined relation between value of fuel command signal, corresponding to fuel flow rate, and accelerator pedal displacement. The fuel command signal of the representative of the selected fuel flow rate is then passed to a section (36) of the computer (20) which passes a corresponding control signal via line (27), to a fuel injector (22), and which also determines the corresponding optimum air flow rate and controls the opening of a throttle valve (16) to provide it. The selection of the respective function defining the relationship of the accelerator pedal movement to actual fuel flow command can be made by the operator or driver via a selector (34), to provide a desired engine response characteristic. Thus, the drive feeling for a vehicle can be varied within a range from normal to either a faster or more conservative engine reaction.
