Title: A compact low-pressure mercury vapour discharge lamp and a method for its manufacture
Inventor: BJORKMAN AKE
IPC: H01J61/10
Filed: 1985-09-25
Granted: 1989-12-28
Abstract: Acompact low-pressure mercury vapour discharge lamp comprises two or more straight tubes (2, 3) which are interconnected by means of couplings (4), to form a discharge chamber between two electrodes (15). The electrodes are located in the outermost ends (7,8) of the discharge chamber of the lamp, these ends being connected in a gas-tight manner to a lamp base (9) incorporating the requisite contact pins (11, 12) and conductors (16).Located downstream of the electrodes (15) in the direction of the discharge current are tube constrictions (13, 14) which define around the electrodes (15) the spaces in which released ions from the electrode emission material are held concentrated, so as to fall back onto the electrode surface upon a change in current phase.The method for manufacturing the lamp commences with a straight glass tube which is coated internally with luminescent powder. The tube is then heated around annular areas adjacent the tube ends. The constrictions (13, 14) are formed in the tube wall as the tube rotates, whereafter the lamp is manufactured in a manner known per se.

Abstract: A thin, plastically formable composite laminate features at least one metallic outer layer (14) and a core (10) of thermoplastic plastic. The metallic outer layers (14) exhibit a flat stress-strain curve which is similar to that of the plastic core (10) and is achieved by specific types of aluminum alloys and by specific alloy treatments. The, preferably 1.5-2.5 mm thick, composite laminates are employed for the manufacture of shaped parts in light weight constructions, especially in automobile, equipment and architectural applications.

Abstract: In packing machines of the type which manufacture packing containers with liquid contents a filling pipe with a valve arrangement situated at the outlet end is frequently used. The valve arrangement in accordance with the present invention comprises a movable valve element which is manoeuvred with the help of pressure variations in the filling pipe. The movable valve element is cup-shaped and is adapted so that it is lifted through excess pressure in the filling pipe from a fixed disc-shaped seat so that an annular discharge opening results.

Abstract: The formation of an outwardly extending curl as the upper rim of a pail or drum having a cylindrical wall by curling the peripheral edge through greater than 360 DEG  relative to the cylindrical wall forms a strong curl able to support, with the aid of a gasket, a leak proof seal during dangerous goods testing. When used with a lug-cover lid, the lugs may be clenched beneath the curl through a re-entrant portion enhancing the security of the seal. Methods of forming the curl in a two-storage operation by forming primary and then secondary curl components, and an improved lug configuration are also described.

Abstract: High power transformers normally contain a low-voltage winding (12), a high-voltage main winding (13) and a tapped winding (14). If the tapped winding is operated in a subtractive and additive manner, when the transformer is excited with an oscillating switching voltage at the resonant frequency of the tapped winding (14), particularly when it is connected subtractively, high voltage amplitudes with respect to earth can occur along the tapped winding (14) at the end of the main winding (13). To reduce and damp-out such resonant frequency oscillations, in the case of known arrangements either each stage or the complete tapped winding (14) was connected in parallel with an R-C element (19, 20). According to the invention, it is now intended that only a single stage of the multi-stage tapped winding (14) is connected in parallel with an R-C element (19, 20), which R-C element also reduces the resonant amplitudes occurring in the other stages because of the transformer coupling between this stage and the other stages. The use of the circuit arrangement according to the invention is expedient in the case of large transformers. This is particularly true in all cases in which a multi- stage tapped winding (14) is provided connected additively and subtractively with respect to the high voltage main winding (13). <IMAGE>

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.

Abstract: A mixer for dry material has a lower section transportable away from the mixer when sepd. from the upper section, which in loading position forms a cover engageable with the lower section. When coupled together the two sections can pivot about a horizontal axis through 180 deg. into a mixing position, using tools mounted in the ''cover'' with a motor-driven shaft. When after mixing the coupled units are rotated back to their initial relative position prior to sepn. and removal of the lower section, the necessary rotation angle of 180 deg. is exceeded by an angle depending on the nature of the material and normally exceeding 10 deg. such that the surface of the mixed material is parallel with its container rim. Finally the tilt is reversed through this corrective angle, with min effect on the solids surface position.

Abstract: The power supply has a three-phase transformer with three secondary windings and a rectifier followed by a lowpass filter to smooth the dc voltage. The second connections of the secondaries (S1-3) are connected to two e-phase star rectifier circuits (11 etc.) that produce two dc voltages of opposite polarity w.r.t. neutral. Each dc voltage is smoothed using an LC filter (SL1, SC1 etc.) whose filtering capacitors ahve a shared point (F) connected via an extra inductor (ZL) to neutral (St). The extra inductor has an inductance chosen so that the load current flows through the extra inductor with independently operated switches (NS).

Abstract: Apparatus is disclosed for filtering melted plastic used in an injection molding system. The apparatus consists of a housing (12) having an inlet (18) and outlet with a cylindrical inner chamber (21) disposed in alignment therebetween, and a tubular filter element (13) threadably mounted in the internal housing. To avoid loosening of the filter element (13), a plurality of spiral surfaces (34, 42) are formed in the filter element (13) that are exposed to the pressurized flow of melted plastic, generating a resultant force that tends to screw the filter element (13) tighter onto its threaded mount (22). The threaded mount (22) is at the inlet end of the tubular element (27), causing it to extend in cantilever fashion axially into the internal chamber (21) and toward the outlet. This creates an annular discharge passage around the filter element (13) that is unobstructed, permitting the filtered plastic to converge smoothly into the outlet.
