Abstract: The invention concerns disposable plastic cutlery set, which as a result of a configuration of the 4 implements normally making up a cutlery set by means of a connection piece 13 are connected until shortly before use, in that the user simply breaks the implements off from each other, which is easy to do because of a recess 16 between the transition piece 12 and the connection piece 13. The disposable cutlery set are produced with a view to providing a cleaner set of cutlery set than are known at present. The sorting after production, necessary thus far, is eliminated. The production can now be fully automatic, both injection moulding and packing, since the packing is done in certain specially designed paper or plastic containers which likewise serve as a shipping package and after being received are easily placed in a cartridge which is in turn placed in a dispenser, so the cutlery set are untouched by human hands, which is quite clearly a tremendous advantage in terms of hygiene, since we use the implements to eat food. The special configuration likewise makes it possible that the cutlery set, packed in paper or plastic containers, do not take up too much room, it is easier to keep the cutlery set in storage, for example aboard an aeroplane, and one does not need to have several different types in stock, since the cutlery set always contains what is necessary. The special configuration makes it possible, through automation, to produce a disposable plastic cutlery set around 45 per cent cheaper than is known thus far. <IMAGE>

Abstract: The invention relates to holographic optical elements which operate on a plurality of wavelengths and with reduced distortions and a process for production thereof. The achromatic, holographic elements are produced by the use of an essentially conventional apparatus and method based upon the phenomenon that any two reflection wavelengths are diffracted at the same angle if the mutual relationship between their construction angles is inversely proportional to the relationship between their sines. In the case of holographic lenses, the diffracted wavelengths are brought moreover to a common focus if the mutual relationship between the focuses during the construction is inversely proportional to the relationship between the sines of their construction angles. Used in connection with a thick reproduction medium, the method produces an optical element with a symmetrical pair of outgoing rays having two independent focuses. <IMAGE>

Abstract: The invention relates to a method for production of concrete, cast ceramics and the like. According to the method, slag or a similar alkali-activated substance is used as the binding agent, and the necessary fillers and additives are mixed into the binding agent in order to form a binding agent mixture which is hardened. According to the invention, a solution which has been obtained by dissolving slag in an alkali activator is added to the binding agent mixture before hardening. When flushing slag is used as the binding agent, a part which is dissolved in the alkali activator used is separated from the slag and at least essentially the whole amount of alkali activator used is added to the binding agent mixture in the form of a solution which contains slag. With the aid of the invention the small voids in the fresh concrete are filled with precipitated crystal particles, so that the strength of the concrete increases.
