Title: Multipath connector for printed circuits - with detachable lid to enable insertion or removal of spring contacts without tools
Inventor: SCHWARZHOFF WOLFGANG
IPC: H01R13/436
Filed: 1980-12-27
Abstract: The electrical contact housing has several columns of pockets for holding the spring contacts, with openings in the outer face through which mating contact pins can enter. The spring contacts are in the form of a rectangular U-shape, or tube, and terminate in a tongue to which an incoming lead can be connected by one of several established methods. These wired contacts enter the housing at the side opposite the entries for the mating contacts. A lid through which the connecting wires are threaded has moulded on T-shaped spring tongues. When the lid is snapped onto the housing these tongues enter the pockets and lock the spring contacts into position. To alter a contact it is only necessary to unsnap the lid and remove to insert the contact by hand. No tools are required. The contact housing assembly is carried in a two part shell (24) by which it is held onto a suitable support or mounting.

Title: Pressure relief valve
Inventor: HEPPNER HANS DIPL ING
IPC: B01J3/02
Filed: 1981-06-19
Abstract: In a pressure relief valve (1) for relieving the pressure of gaseous or fluid media, the restriction is achieved by means of a helical circumferential groove (5) of the valve piston (3), the groove cross-section expanding in the piston longitudinal direction. The groove cross-section located just at the start of the restrictor region (10) of the valve bore (11) in this case determines the flow rate. The flow rate can thus be regulated by axial displacement of the valve piston (3) in the valve bore (11). The pressure relief valve according to the invention is suitable in particular for relieving the pressure of abrasive media and of liquid-solid suspensions with high pressure differences. <IMAGE>

Title: Arrangement of the hydraulic lines of loading machines with pivotable crane jibs
Inventor: SVENNING SVEN GOTTFRIED WERNER
IPC: B66C13/12
Filed: 1982-01-14
Abstract: The subject matter of the invention is an arrangement of the hydraulic lines of a hydraulic loading machine, comprising a supporting column (3) and a jib system with a rear jib (lifting jib 1), one end of which is pivotably connected to the column and the other end of which is pivotably connected to a front jib (level-luffing jib 2), the jibs being pivotable in relation to the column and in relation to one another by means of hydraulic cylinders (4, 5), and at least one hydraulic line (H), which consists at least partly of a flexible tube, extending from the column (3) up to and along the lifting jib (1) as well as up to and into the level-luffing jib (2). The invention is distinguished by the fact that the hydraulic line, over that section where it spans at least one of the two articulation points (30 and/or 31), has a length and radius of curvature which are dependent upon the pivoting angle at the articulation point and thus vary, and that the hydraulic line, in order to make possible the requisite changes in this length and this radius of curvature during changes in the pivoting angle at the articulation point, is arranged in such a way that it forms a tube loop (HB, HBY) at a point at a distance from the respective articulation point, which tube loop (HB, HBY) enables the hydraulic-line section spanning the articulation point to be shortened and lengthened, as a result of which tube loops at the articulation point can be eliminated. <IMAGE>
