Title: Measuring, marking-off and/or scanning tool and a toolholder adapted thereto
Inventor: KUEMMERER HANS-HELMUT DIPL ING
IPC: A43B13/02
Filed: 1981-01-30
Abstract: A tool (14) for measuring, marking off and/or scanning and a toolholder (10) adapted thereto are proposed, which toolholder (10) contains at least one bore (13) for inserting a corresponding cylindrical insert shaft (21) of the tool (14). The bore (13) has at one point a rebound-like chamber (29) with an axial transition edge (30) in the transition zone to the bore section (31). On its end section (32), which upon insertion completely fits the bore section (31), which is situated in front of the chamber (29), beyond the transition edge (30) thereof, the insertion shaft (21) has a stopper (34), in particular an O-ring (35). The latter projects radially in an unloaded fashion, can be pressed in radially upon insertion of the insert shaft (21), and projects radially again automatically upon being unloaded. When the tool (14) is withdrawn from the bore (13), the stopper (34) strikes against the transition edge (30). This prevents the tool (14) from dropping down of itself in the event of a holder with easy movement and of vertical alignment or, e.g., that in the case of a close fit and being withdrawn with the application of force it falls from the person's hand when breaking free, as a result of which injury to persons and material damage could arise. <IMAGE>

Title: Tripping mechanism for an electrical snap-action switch
Inventor: HARTOP ROBERT WILLIAM
IPC: H01H3/00
Filed: 1981-04-15
Abstract: A tripping mechanism for an electrical snap-action switch consists of a moving contact element which is supported such that it can pivot, a tripping lever which is supported such that it can pivot, and a leaf spring which is clamped in between the lever and the moving contact element. The mechanism trips in two stages, the lever carrying out a limited pivoting movement in the first stage, while the moving contact element still remains in the quiescent position until the lever pivots in a limited manner with a snapping movement, as a result of which the moving contact element is allowed to switch over with a snapping movement during the second stage. The two-stage tripping prevents chattering or bouncing of the moving contact element before switching.

Title: Noise-prevention wall
Inventor: SCHLUETER ULRICH
IPC: E01F8/00
Filed: 1981-08-06
Abstract: The invention relates to a noise-prevention wall made of individual elements which can be placed next to one another. In order to improve a noise-prevention wall with regard to its maintenance-friendliness and weather-friendliness, it is envisaged according to the invention that each individual element is a hollow cassette which is filled with damping material and the surface of which facing the noise source consists of parallel vertically aligned profiled bars placed next to one another and the rear wall of which facing away from the noise source is designed as a closed surface. The closed surface preferably consists of planks placed next to one another, which can be placed next to one another tightly and firmly by means of positive elements, e.g. groove and tongues. As material for the components of an individual element such as planks, profiled bars and frames, tropical hardwood, e.g. bongossi wood, is advantageously suitable.
Patent DE-3136114-A1 (DE)
Title: Inclined staircase lift
Inventor: BIHLER FRANZ
IPC: B66B9/08
Filed: 1981-09-11
Abstract: The invention relates to an inclined staircase lift, consisting of a platform (3') which can be moved on a transport device running along a staircase. Barriers (1, 1') are provided on the ascending and descending side. The barriers (1, 1') are mounted on a side wall (2') or the like connected to the platform, can be pivoted from a vertical, pivoted-upwards approach position into a horizontally directed locking position and are locked during travel against pivoting upwards and downwards. A barrier can be swung up only at the stops. When not in use, the platform (3') is swung up against the side wall (2') and the barriers (1, 1') are pivoted downwards so that they come to lie over the platform (3'). So that the barriers (1, 1') can only be pivoted downwards when the platform (3') is swung up but not during travel, the invention provides for a pivotable lever (5) which, as long as the platform (3') is not swung up, is constantly pressed into the pivoting area of the barrier (1, 1') by a spring (9) and at this location forms with a laterally projecting extension (7) a limit stop to prevent the barrier (1, 1') from pivoting downwards. When the platform (3') is swung up, an extension (3) provided on the platform runs into the lever (5) and pushes it against the force of the spring (9) out of the pivoting area so that the barrier (1, 1) can be pivoted downwards (Fig. 5). The pivot axes of the two barriers (1, 1') can be coupled via a slip clutch (12) so that when one barrier (1, 1') is pivoted downwards or upwards the other is carried along with it. <IMAGE>

Patent DE-3209917-A1 (DE)
Inventor: MEIER GUDRUN
IPC: B23P6/04
Filed: 1982-03-18
Abstract: The cast iron housing of a pump for conveying gravel or the like can be repaired by inserting into a recess in its internal surface a casting which at least substantially fills the recess. The recess develops as a result of washout, cavitation and/or other influences when the housing is in use. The casting is obtained by pouring molten metal into an impression which is formed in a mold by a pattern obtained by filling the recess with a hardenable plastic surface. The impression is overlapped by a cover having a surface which is complementary to the internal surface of the housing, and such cover is used for admission of molten metal as well as for escape of air from the impression. The casting is fastened to the housing by bolts portions of which are embedded in the casting during pouring of molten metal and extend through complementary holes of the housing or through the deepmost portion of the recess if the latter extends all the way between the internal and external surfaces of the housing. In addition to or in lieu of mechanical fasteners, the casting can be secured to the housing by adhesive. A seal can be inserted between the casting and the housing so as to prevent leakage of flowable substances into the recess around the casting. A casting can be removed after a certain period of wear to be replaced with a fresh casting so that the useful life of the housing can be extended beyond the useful life of a single casting.

Title: Device for cleaning hollow filters for powder coating plants
Inventor: VOEHRINGER GERHARD
IPC: B05B14/48
Filed: 1982-04-17
Abstract: A device housing (1) is subdivided by partitions (2 + 3) into a jet chamber (4), a filter chamber (5) and a blower chamber (7). A hollow filter (12), rapidly exchangeable by means of a tensioning and holding apparatus, having a cylindrical, zigzag-folded filter element (16), is mounted in the filter chamber (5) on the partition (3) so as to be rotatable and advanceable by means of an advancing mechanism (43). A blowing nozzle head (34) is moved to and fro tight against the periphery of the filter element (16) in the direction of the casing by a compressed air cylinder (46). In the end positions, a pressure impulse nozzle (29) is also briefly operated by the advancing mechanism (43), which pressure impulse nozzle is fitted close to a compressed air vessel (30) and which blows through a trumpet-shaped inlet tube (26) into the clean gas interior (20) of the hollow filter. A blower (8) sucks air from the raw gas space (32) of the filter chamber through a post-filtering unit (51) and delivers exhaust air for the most part via the jet chamber (4) and inlet tube (26) into the clean gas space (20). A first fraction of the completely purified powder is collected true to colour in a collecting vessel (26), a further powder fraction in a collecting vessel (53) beneath the post-filtering unit (59). In place of the pressure impulse nozzle (29), if required, a movable blowing nozzle can alternatively be mounted on the clean gas side. <IMAGE>

Title: Complete roof made of precast reinforced concrete parts
Inventor: BENKERT BERNHARD
IPC: E04B7/00
Filed: 1982-05-07
Abstract: The invention relates to a roof construction, in which rain-proof, constraint- and maintenance-free flat roofs of any desired dimensions result even with precast reinforced concrete parts laid with open joints. The complete roof can be used for all high structures. It is distinguished in particular by simplicity of mounting and by the small number of different elements, which can be laid dry. The rainwater is drained in the manner of a cascade. The robust parts require only a minimum of fitting accuracy during laying. As mounting progresses, it is possible to work in the space below in a manner protected against rain. The roof can be designed both without and also with heat insulation, irrespective of weather conditions. Conventional roofing work is dispensed with. Figure 1 of the application shows the characteristics. <IMAGE>
