PROBLEM: Nosná deska pro přesné opracování tenkých  vysoce planparalelních elementů, především  z monokrystalických materiálů s vysokou  přesností opracování až na 1/20 λ,  která je vytvořena z nízkoroztažného materiálu,  jako jsou vysocekřemičitá skla a především  tavený křemen, kde výsledku je dosaženo  tím, že je opatřeno rýhováním, kde  vzájemná vzdálenost rýh činí 0,5 až 1 násobek  jejich šířky a hloubka se s výhodou blíží  jejich šířce.

SOLUTION: Supporting plate for precision thin processing  highly planparal elements, especially  high-grade monocrystalline materials  machining accuracy up to 1/20 λ,  which is made of low stretch material  such as high-siliceous glass and above all  fused quartz where the result is achieved  by striating it, where  the distance between the grooves is 0.5 to 1 times  their width and depth are preferably approaching  their width.

SOLUTION: In the present invention there is disclosed a fuel injection system comprising a fuel injection pump, a pump piston (1), said pump piston is driven by a cam drive provided with at least one cam and defines a pump work chamber (10) which is used to supply at least one fuel injection valve (13) with fuel injection quantities brought to injection pressure, an electrically controlled valve (24) for connecting the pump work chamber (10) of the fuel injection pump to or closed off from a discharge chamber (17) in order to control the injection, and with interruption of the injection between one pre-injection and one main injection per injection event, the at least one cam (5) is embodied so that on a cam edge side that moves the pump piston to a feed stroke, said at least one cam has a first partial region (V) in which the pump piston executes a feed stroke to carry out a pre-injection, said at least one cam has a second partial region (P) in which after an ending of the pre-injection, the piston (1) essentially remains in a position the piston reaches at the ending of the pre-injection stroke and then, in order to execute the feed stroke for the main injection, said at least one cam has a third partial region (H), wherein the electrically controlled valve (24) is triggered so that at a low speed, the control valve is closed before the beginning of the first partial region (V) and in the first partial region (V), the valve is opened to end the pre-injection, and then, in order to execute the main injection, at a beginning of a third partial region, the valve is closed again and in this third partial region of the cam, the valve is opened again before the top dead center of the cam is reached, and that at a high speed, in order to initiate the main injection without a preceding pre-injection, the valve is closed within the second partial region (P) and is opened again within the third partial region in order to end the main injection before the top dead center is reached.

PROBLEM: Je v principu obvyklé křídlovky pro předeni, je však zjednodušená. V ose   křidélek a jejich rotace je pevný osový čep,kol něhož se v několika ovinech oviji křidélky přást a stahem s něho se tvoři zákruty a tedy i příze. Jako druhý způsob provedení je místo čepu v ose křidélek upevněná trubička a z ovinů přástu na ní při jejich průvleku trubičkou a odtahem se vytváří zákruty a tím i příze.

SOLUTION:
It is in principle the usual flugelhorn for spinning, but it is simplified. In Axis  the ailerons and their rotation is a fixed axle pin, in which the wings are wrapped in a few wraps and the twists and yarns are formed by the contraction with it. As a second embodiment, a tube is fixed in place of the pin in the aileron axis, and bends and thus yarns are formed from the overwrap wrapping during their passage through the tube and the exhaust.
