Title: Valve cap for pneumatic tyres
Inventor: ACHTERHOLT RAINER
IPC: B60C23/00
Filed: 1983-10-28
Granted: 1985-01-31
Abstract: A valve cap (10) makes it possible to indicate a pressure loss in a vehicle tyre. For this purpose, a pressure chamber (30), which is closed off by a diaphragm (26) and communicates with the interior of the tyre, is formed in the valve cap (10). This diaphragm (26) lifts an indication element (40) counter to the force of a spring (34) into a position which corresponds to the tyre pressure. During this outward movement of the indication element (40), a marking element (46) is taken along by the said indication element but, unlike the indication element, rubs against an elastic ring (36). If the tyre pressure falls, the indication element (40) moves into the sleeve but the marking element (46) is held in the original position due to the friction force produced by the elastic ring (36). The extent to which the marking element (46) protrudes beyond the indication element (40) is directly proportional to the pressure loss. <IMAGE>

Title: Apparatus for correcting the sabre which occurs during the punching of strips and taped components
IPC: B21D1/00
Filed: 1988-07-19
Granted: 1989-09-28
Abstract: The invention relates to an apparatus for correcting the sabre in the punching of strips and taped components. Stresses are introduced when cutting and embossing operations are performed on one side during punching and these stresses lead to strip curvature (sabre). In order to be able to perform a correction of this sabre during the punching operation itself, the invention envisages that the strip (8) should run through a measuring section, the inlet and outlet of which are formed by a guide (2) matched to the strip. Arranged approximately in the centre of the measuring section is a measuring slide (3) supported in a low-friction manner which is deflected as a function of the sabre of the strip. The extent of the deflection is converted in an electronic measuring circuit (4) into an electrical signal and this is used to control a servomotor (5) which acts on two notching punches (7, 9) to produce the correction of the sabre. <IMAGE>
Patent DE-3837537-C1 (DE)
Title: Rotation limit switch
IPC: H01H19/18
Filed: 1988-11-04
Granted: 1990-02-22
Abstract: The rotation limit switch has a retaining frame (3, 5, 7) in which a threaded spindle (15) is mounted such that it can rotate. This threaded spindle (15) has a spindle nut (31) which can be displaced along the threaded spindle (15) during rotation of said threaded spindle (15). The spindle nut (31) is guided on a slotted sleeve (25), which surrounds the threaded spindle (15) coaxially, and has a switching cam (33), which emerges out of the slot (35) of the slotted sleeve (25), for operating a switch (37). The slotted sleeve (25) is coupled in a rotationally fixed manner, via a step-down drive (41, 43, 45), to the threaded spindle (15), which drive reduces the rotation speed of the slotted sleeve (25), which rotates in the same direction as the threaded spindle (15), with respect to the rotation speed of the threaded spindle (15). In this way, the feed rate of the threaded spindle (31) per revolution of the threaded spindle (15), and the monitoring range of the rotation limit switch, can be increased without any mechanical weakening of the thread of the threaded spindle (15). The thread of the threaded spindle (15) can be designed as a cross thread which moves the spindle nut (31) in a reciprocating manner when the direction of rotation remains the same. By suitably dimensioning the components, it is possible for the switch (37) to be operated in only one axial movement direction of the spindle nut (31), which results in a further increase in the monitoring range of the rotation limit switch. <IMAGE>

Title: Process and apparatus for recycling waste containing plastic and/or organic material
Inventor: POESCHL GUENTER
IPC: H05H1/46
Filed: 1993-08-19
Granted: 1994-11-17
Abstract: By means of the apparatus (10) described, waste of all types, in particular plastic waste, of a single type or mixed, are broken down to their base components and can then be reused, e.g. plastic waste from scrap refrigerators. For this purpose, the waste (12) is impinged by high-intensity microwave energy using magnetrons (28) in a vacuum chamber (16), a previously introduced gas, e.g. argon, being ionised, which has the effect that gaseous constituents leave the waste (12) and form a plasma under the action of the microwave energy, which plasma finally completely breaks down the waste (12). The plasma is ignited by passing hydrogen into the vacuum chamber (16) containing the ionised gas. The waste (12) is reduced by the action of the plasma and hydrogenated by the hydrogen. Gaseous constituents of the waste (12) are removed via outlet lines (24, 26), and a liquid or pulverulent residue in a waste reception vessel (13) is removed together with this from the vacuum chamber (14). <IMAGE>
