Title: Process for inserting a dowel, and dowel provided therefor
Inventor: BRUECKL FRITZ
IPC: F16B13/08
Filed: 1981-03-18
Abstract: In the case of a process for inserting a dowel which has a bolt, provided with a cone-shaped end part, and an expanding sleeve enclosing the bolt, blows are exerted onto the sleeve in the axial direction thereof and a retaining body provided with a hole is placed onto the cylindrical end part, directed away from the cone-shaped end part, of the bolt. In order to produce a connection which is cheaper than a screw thread, given a dowel which is inserted into a bore with its cone-shaped end part and given a retaining body which is placed on the other end part, the latter is subjected to blows such that on said end part there is formed a rivet head which engages over the hole in the retaining body. For this purpose, use is made of a dowel, the bolt of which has its end part, directed away from the cone-shaped end part, designed such that, once the dowel has been inserted into a dowel hole, a rivet head which projects radially beyond the receiving hole in the retaining body can be produced.

Title: Device for the safeguarding and feedback control of 3 to 5 circuit hydraulic brake system, particularly for motor vehicles
Inventor: HOFMANN KLAUS
IPC: B60T17/04
Filed: 1981-04-10
Abstract: The invention relates to the sphere of motor vehicle engineering. The aim of the invention is to permit balancing of pressure between the energy reservoirs in the preconnected 2-circuit safety valve in the event of defects in auxiliary circuits or secondary consumer circuits, even whilst safeguarding the main circuits in the high pressure range. The object of the invention is to cancel the safety pressure in the high pressure range in these instances and to shift it into the normal pressure range. The essence of the invention lies in the fact that above the control springs usual for the normal pressure range a 2-circuit safety valve (1), a control piston (15), is arranged, the control command for which is emitted by the secondary consumer circuit (V). The control springs are composed of a spring (14), which is supported between working and control pistons and a further spring (13) which is inherently pretensioned and only becomes operative in the event of a certain stroke by the working piston (3). Due to these force graduations and other stroke correlations, the initial power supply is possible even in the event of a defective circuit. The sphere of application of the invention is multicircuit brake systems on motor vehicles. <IMAGE>
Patent DE-3117409-A1 (DE)
Inventor: MAIER JOSEF
IPC: E04G11/28
Filed: 1981-05-02
Abstract: Climbing forms for stepwise erection of concrete walls have a platform which is supported by a frame having elongated carriers extending at right angles to the outer side of the wall to be erected and being removably suspended on anchors which are embedded in the wall. The platform supports a pair of parallel guide rails for a form member which carries the boarding of the climbing forms. The rails guide the carriages of the form member so that the boarding can be moved between an advanced position in which it is adjacent to the cavity into which concrete is to be poured and a retracted position in which the wall and the boarding define a passageway which is accessible to workmen on the platform so that the workmen can clean and/or otherwise treat that side of the boarding which faces the wall. The guide rails are mounted in such a way that the platform need not be provided with uncovered slots, gaps, cutouts or other types of openings which would endanger the occupants of the platform or would permit objects to drop from the platform and thus endanger the persons or equipment below the climbing forms.
