Title: Shielding-gas arc welding method and appertaining shielding gas
Inventor: STENKE VIKTOR DIPL ING
IPC: B23K35/38
Filed: 1993-08-17
Abstract: The invention relates to shielding-gas arc welding methods making use of the melting (burning-off) electrode and also the non-melting electrode, which involve, during welding operations, continuously supplying the weld spot (welding point) adjacent to the electrode with a stream of shielding gas, the shielding gas being composed for a major part of argon and/or helium. Such welding methods are known in many versions, and quite generally they enable the most diverse materials (ferrous and non-ferrous materials) to be welded together satisfactorily. In a number of practical cases, e.g. with respect to aluminium welding, however, it is possible for welding to proceed in a non-optimal manner, not uncommonly particularly with respect to the important arc stability. This disadvantageous situation is improved markedly, according to the present invention, by the shielding gas being additionally mixed, in a proportion range of no more than from 20 to 5000 vpm, preferably from 50 to 3000 vpm (from 0.005 to 0.30 % by volume) with additions of     heavy noble gases (Kr, Xe) and/or stable, simple biatomic or triatomic non-noble gases (H2,O2, CO2, N2O, NO2 and the like) and/or gaseous, stable organic compounds, preferably C1 to C4 hydrocarbons (CH4, C2H4), having ionisation energies between 8 and 17 eV, preferably 8 and 14.3 eV.

Title: Device for the fixing and securing of a valve
Inventor: BODENHAUSEN ECKHARD DIPL ING
IPC: F02M55/02
Filed: 1993-09-03
Abstract: In known devices for the fixing and securing of a valve, for example a fuel injection valve, a part of a bayonet fitting is provided directly on the fuel injection valve whilst the corresponding part is arranged on a fuel distributor. As a result only fuel injection valves which have elements of the bayonet fitting can be used in the fuel distributor. A connector cap to be placed on the fuel distributor must be fixed with mechanical fasteners, such as screws, for example. In the new device the fuel injection valve (1) does not have any functional elements for fixing in the valve seating aperture (3) of the fuel distributor (5). Instead of this the rotatable holder (37) is used, which with the inner pressure element (39) prevents the fuel injection valve (1) from slipping and with the outer fixing ring (52) as a part of the bayonet fitting (60), the corresponding bayonet pins (58) of which are formed on the fuel distributor (5), provides for a simple and secure fixing to the fuel distributor (5). The holder (37) is sealed off by the sealing cap (83) slipped on to the holder (37), through which cap the connection cables (40) also run. The device according to the invention is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with applied ignition. <IMAGE>

Title: Woven belting for paper-making machines
Inventor: LENK HANS-JOACHIM
IPC: D21F1/00
Filed: 1994-02-07
Abstract: To produce a woven belt, with a seaming to join the ends for a continuous belt structure, the warp ends are passed alternately round a steel wire and woven back into the material. During weaving, the wefts extend by a given length outside the seaming width to be aligned, drawn into a reed and tensed by a clamp. The woven belt is broken down without distortion, to twice the seam width, by the shed operating system of the loom. The warps at one side of the shed mechanism are taken in a lease and fixed and are taken from the lease at the other side to be laid in the shed for positioning with the reed at the previous edge marking. The woven belt is reconstructed with looping so that the lock of the final weft is turned and woven back round the steel wire at the edge with following wefts also turned round it and woven in.

Title: Picture tube processing method e.g. for separating glass types in television tube recycling
Inventor: ADIB MASSOUD
IPC: H01J9/52
Filed: 1994-04-22
Abstract: The processing method involves picture tubes which have a face plate made from barium glass, and a cone and a neck both made from lead glass. The picture tube is scratched around it with a diamond cutter in the region between the face plate and the cone, where the 2 glass types meet. The tube is then subjected to mechanical vibrations at a resonant frequency such that the face plate is separated from the cone along the scratched line.If the boundary between the different glass types is not clearly defined, 2 circumferential scratches can be made on either side of the zone of uncertainty, thus splitting the tube into 3 pieces which can be recycled separately. The vibrations can be generated by piezo elements.

Title: Shock force meter for combat sport e.g. boxing or martial arts
Inventor: KO EUI-MIN
IPC: G01L5/00
Filed: 1994-07-25
Abstract: An evaluation unit is used for determining the characteristic curve and the equivalent inertia mass. An acceleration pick-up is arranged at the contact surface (e.g. in blow padding or body protective vest). This pick-up measures the acceleration curve (a(t)) of the contact surface. The displacement time curve of the contact surface is then computed, and from this and the equivalent inertia mass, the ''dynamic'' force time curve (F2(t)) is computed using the data obtained, also the ''static'' energy curve (E1(t)). The dynamic energy curve (E2(t)) is then computed from the curve (F2(t)) and the displacement time course using the evaluation unit. The total energy curve (E(t)) is computed from the energy curve (E1(t),E1(2)) using the evaluation unit, also the power time curve (p(t)). Quantifiable variables such as the max. force, max. power, average power, impact strength and total energy are computed by the evaluation unit. All the computed curves are indicated on a monitor screen.
