Patent DE-3130971-A1 (DE)
Title: Plastic toothpick
Inventor: FLORJANCIC PETER
IPC: A61C15/02
Filed: 1981-08-05
Abstract: In a plastic toothpick the tip (2) has a recess (4) and the shaft (1) used as a handle has an elongate recess (5). The recess (4) leaves only a thin floor (11) of the tip which makes the latter flexible and permits it to be pushed, while increasing its width and reducing its height, into fairly narrow interdental gaps without exerting any pressure on the tooth flanks. The recess (5), which is expediently opposite the recess (4), in the shaft (1) reduces the overall weight and permits it to be taken up on a comb-like tool for processing purposes, e.g. for printing and severing from the sprue. <IMAGE>
Patent DE-3131565-A1 (DE)
Inventor: GUBLER ROLAND
IPC: B05B15/12
Filed: 1981-08-10
Abstract: A spray-coating booth having on its side walls several air cleaners with easily interchanged and cleaned filter units that are relatively light in weight and can be carried by hand. In accordance with the design of the booth, the dimensions of the spray-coating area can be varied and the filter units can be interchanged with other types of units such as sprayers. Undesirable accumulation of powder is avoided because the air cleaners continuously precipitate powder filtered from the air. Powder transporting means within the booth, which may be inclined chutes with a fluidized bed, transport this excess powder from beneath the air cleaners at the side wall to the floor of the booth. The floor of the booth extends below the entire spray coating region and thereby also serves to collect excess spray powder which falls directly upon it. The powder is then returned for use to the spray-coating region.

Title: Process for the recovery and purification of amethopterin
Inventor: GUSTMANN HARTMUT
IPC: C07D475/08
Filed: 1981-11-14
Abstract: A process for the recovery and purification of amethopterin from solutions, in particular urine, wherein common renal catabolites, metabolites and synthesis by-products are depleted or separated off by precipitation with an alkaline earth metal salt solution, precipitation of the amethopterin with a metal salt solution, treatment of the precipitate with a complexing agent, and subsequent chromatography of the redissolved amethopterin. An electrophoretic purification step can additionally be carried out. When working up large-volume solutions, the amethopterin is first bound to an ion exchanger, optionally transported to the reprocessing site, eluted from the ion exchanger and then purified in the indicated manner. The amethopterin obtained by the process according to the invention is of greater purity than commercially available preparations.
Patent DE-3150142-A1 (DE)
Title: Electric panel heating element
Inventor: HILLINGER ERICH
IPC: A47L15/42
Filed: 1981-12-18
Abstract: In electric heating elements which, e.g. in washing and dishwashing machines or water heaters, are used to heat liquid media, especially water, it is necessary to keep the thermal surface loading as low as possible in order in this way to combat the calcification of the heating elements, which diminishes not only the effectiveness of these elements but also their service life. The same also holds for the heating of oils or the like, where in the event of excessive surface loading the risk of cracking of the oil arises. A low surface loading requires, above all, an effective and very uniform heat transfer from the actual heater to the contact surfaces of the heating element, which dissipate the heat, for their part, to the medium to be heated. This requirement is fulfilled in the panel heating element according to the invention when one or more tubular heaters (2, 3) are embedded by means of a metal powder (4) in a metal container (1) of flat configuration which forms the outer shape of the heating element, and this structure (1-4) is pressed to produce a unit at a high pressure which intensely compresses the metal powder (4). <IMAGE>

Patent DE-3222782-A1 (DE)
Title: Plastic film for use as dielectric in capacitors
Inventor: RUDNAY ANDRE DE DR
IPC: H01G4/20
Filed: 1982-06-18
Abstract: The present invention relates to a plastic film for use as dielectric in electrical, preferably self-regenerating (autoregenerative), capacitors. To suppress the corrosion which occurs in such films, for example those made of polypropylene, in the course of time, a catalyst poison is added to the plastic material. The catalyst poison may either be added to the plastic compound or subsequently applied to the plastic film, for example spread on in a solution. As a result of using a catalyst poison, the behaviour of a self-regenerating capacitor having a plastic film as dielectric is equivalent to that of a metal/paper capacitor.

Patent DE-3245090-A1 (DE)
Inventor: BALD WILFRIED
IPC: B21B31/18
Filed: 1982-12-06
Abstract: A roll stand has a frame, a pair of small-diameter and substantially parallel working rolls defining a workpiece nip, and respective journal blocks supporting the working rolls in the frame for rotation about substantially parallel axes flanking the nip. These working-roll journal blocks and the respective working rolls can be axially shifted in the frame and the working rolls can be bent positively and negatively, that is respectively convex and concave toward the workpiece. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls. Respective journal blocks support the backup rolls in the frame for rotation about substantially parallel axes flanking and generally coplanar with the working-roll axes. A strip is passed repeatedly in a multipass run through the nip generally perpendicular to the plane while the working rolls are pressed against the workpiece to reduce its thickness. The working rolls are axially displaced relative to the workpiece a plurality of times during the run to change the region of contact between the workpiece edges and the working rolls during the run. The working rolls are also bent at least to maintain the workpiece thickness downstream of the nip generally uniform.
Patent DE-3245906-A1 (DE)
Title: Tubular projectile
Inventor: SCHLEICHER ULRICH DR ING
IPC: F42B10/34
Filed: 1982-12-11
Abstract: Tubular projectiles (1, 15) experience, during their trajectory, a relatively low oscillation with respect to the ideal flight axis. Conventionally, these projectiles have a flow cone, on which the compression shock (11) bears directly in the event of supersonic flow. Sharply alternating compressive stresses thereby act on the projectile, and the projectile reacts to these in a highly sensitive way. By means of a relatively short outer cone (4) on the flow cone (3, 16), the projectile (1, 15) is insensitive, without its behaviour as a whole being changed appreciably. <IMAGE>
