Abstract: The invention relates to a method for producing 1-methyl-3-nitroguanidine, comprising the following steps: a) reacting chlorine cyanide or bromine cyanide with methylamine in the presence of an inert organic solvent at temperatures of -30 to 0  DEG C; then b) allowing the methylcyanamide formed in step a) to react directly with amoniumnitrate in a temperature range of 80 to 180  DEG C and a pressure range of between 1 and 50 bar, without further reprocessing; and c) dehydrating the methylguanidine nitrate formed in step b) after removing the solvent at temperatures of -20 to 60  DEG C; and d) finally, isolating the 1-methyl-3-nitroguanidine formed in step c). The inventive method provides a particularly environmently friendly and technically simple means of producing 1-methyl-3-nitroguanidine in yields of at least 85 % and with more than 98 % purity, from economical starting materials.

Abstract: A vision aid in the form of telescopic spectacles has two lens systems, which each comprise at least one objective lens ( 70 ) and one eyepiece ( 71 ). An autofocussing element which changes the focal length of the lens systems for sharp focussing thereof according to the distance of the telescopic spectacle from the object is assigned to the lens systems. Furthermore, an element for changing the magnification factor by changing the focal length of the lens systems ("zoom") and finally an element for matching the parallax between the lens systems of the vision aid to the focal length which has been set according to the distance of the telescopic spectacles from the object are assigned to the lens systems. The parallax is adapted using adjustable optical elements ( 11 ) which are located in the beam path of the lens systems, with which elements the angle ( 13 ) between the beam paths ( 14 ) running from the lens systems ( 1 ) to the object can be changed.

Abstract: A filler stub with a screw/bayonet fitting cap (1) has a safety catch (13,14) which prevents the cap from being thrown off the fitting if it loosens due to vibration etc. To ensure that the safety catch is engaged every time the cap is fitted the catch is engaged during the initial part of the cap fitting action ie. the operator is in no doubt that the cap is secured. The cap is secured by a screw or bayonet action and is sealed via integral seals (6). An alternate design has the catch engaged before the cap closing action can be applied.

Abstract: The invention relates to a compact, electrodeless, low pressure gas discharge lamp which is characterised by a long shelf life and high light efficiency and light density. The inventive gas discharge lamp comprises a ball-shaped, ring-shaped, pear-shaped or ellipsoidal glass body which is used as a gas discharge receptacle, on the inner gas surface of which a layer containing at least two luminous substances is applied. The side of the glass bulb facing the gas discharge and/or the layer containing luminous matter and exposed to the gas discharge in the discharge receptacle are coated with a chemically, largely inert protective layer consisting of an oxide. The electrical energy is introduced into the discharge receptacle in an inductive manner using a ring-shaped closed ferrite core, preferably MnZn soft ferrite, which is partially located inside the discharge receptacle and is provided with a primary winding which is connected to an RF source in the frequency region of between 100 kHz and 500 kHz by means of a resonant LC coupling circuit. Part of the ring-shaped ferrite core is introduced into the discharge receptacle by means of a vacuum-tight passage which is arranged in the glass body. The part of the ferrite core, the primary winding and the coupled RF source in the form of an electronic push-pull circuit are arranged in the base of the lamp. The luminous substances used are derived from, for example, the compounds gadolinium-magnesium pentaborate silicate, alkaline earth aluminate, cerium-magnesium aluminate et al., and are activated by ions of rare earth elements and/or manganese, lead, antimony, tin and bismuth. The inventive compact, electrodeless, low pressure gas discharge lamp is used as a light source for general and communal lighting, inside and outside, in the fields of medicine and cosmetics.

Abstract: The machine has a housing with a truncated cone-shaped breaker tool (4,4'), enclosed by a breaker jacket (5,5'), to define a breaker chamber (6,6'), all of defined dimensions. For larger sizes of appliance, the breaker diameter is increased, but the height (h) of the breaker chamber remains mainly the same, independent of breaker tool and jacket diameters, across a series determined by capacity, and corresponds approx. to the height of the smallest breaker within that series. The narrowness of the breaker chamber between intake and discharge is approx. the same for all sizes within a series. The distance between the center of gravity of the breaker tool and the bearing points of a breaker shaft, remains mainly the same with increasing breaker size.

Abstract: The invention relates to a method for separating biogas, fermented biomass and water produced in a biogas fermenter by fermentation of a biosubstrate. After fermentation of the biosubstrate used, the degassed fermented biomass or fermented material, by stopping the agitation, is subjected to a sedimentation phase in a biogas fermenter (1). Once the solid biomass has sedimented and the suspended matter floats on the surface, the sedimentation layer forming the sedimented matter is removed. Said sedimentation layer is subjected to an additional fermentation step in a separate closed sedimentation fermenter (2). The biogas and humidity thereby produced are led into the gas-carrying section of the biogas fermenter (16) and the sedimentation water is led in a second step into a separate sedimentation water basin (3) or directly into ponds (5).

Abstract: When subdividing cast billets, the flame-cutting machines used for this are clamped via clamping jaws (17) tangentially against the longitudinal edge of the billet (19). In this process, the cutting torch of the clamping jaws is swivelled into an initial cutting position and positioned by means of control elements coupled to the clamping jaws and the cutting torch. In order to avoid an adjustment of the control elements in the case of billets of different widths and heights and in the case of different continuous-casting billet forms, it is proposed according to the invention that the axes of rotation (20, 21) of the clamping jaws (17) and of the cutting torch (28) be situated in a common horizontal or vertical plane (22) and the clamping jaws (17) be situated over the centre (23) of their axis of rotation (21) and that, on swivelling the clamping jaws (17) with the cutting torch into the clamping position or initial or final cutting position, the longitudinal axis (26) of the clamping jaws and the longitudinal axis (28) of the cutting torch swivel virtually parallel to one another in the cutting plane. <IMAGE>

The elastic parts (3, 4) have surfaces (9, 11) which are differently positioned axially (8) in the unloaded state and designed as supports. These support surfaces change according to the load (12) acting on the damping component. This damping component is of universal application as it is not designed solely for specific loads to be kept within relatively close limits. It thus makes it possible to damp loads over wide limits with one and the same component.
