Patent DE-3738548-A1 (DE)
Inventor: STOEFFLER ALBERT
IPC: B65D47/34
Filed: 1987-11-13
Abstract: The dispenser for viscous materials has a housing (1), having a piston (2) which can only be displaced in the emptying direction, and an outlying actuating handle (B), by means of which a force can be applied to a pump element which can be compressed in the direction of the piston (2), the pump element having an inlet valve (V1) and an outlet valve (V2), and the outlet valve (V2) being arranged in the actuating handle (B), the outlet valve (V2), moreover, being spring- loaded in its closed position by means of spring elements which are moulded on and project into the interior of the dispenser. For a design which is simple in terms of manufacture and offers advantages in use, provision is made for the spring elements to be constructed as spring legs (21) which are supported on a collar (22) of the actuating handle (B) and are moulded directly onto the valve disc (20) in a free-standing manner.

Patent DE-3739824-A1 (DE)
Title: Pilot-controlled three-way pressure-regulating valve
Inventor: WOELFGES HANS
IPC: G05D16/16
Filed: 1987-11-24
Abstract: The invention relates to a pressure-regulating valve with a pilot-control valve. A consumer connection can be connected selectively to a pump and to a tank by the main regulating piston. The main regulating piston is loaded by the pump pressure counter to the control pressure. The control-pressure space is connected to the pump-feedline. The pilot-control valve regulates the flow-off from the control-pressure space to a lower pressure level. The regulating behaviour of the pressure-regulating valve is thereby improved. Moreover, the pilot-controlled valve supplies a pre-holding force which initiates an early closing movement of the main regulating piston, so that the transient behaviour is improved.

Patent DE-3800725-A1 (DE)
Title: Sealing ring for screwed pipe couplings
Inventor: BLIESENER DIETER DIPL ING
IPC: F16L19/06
Filed: 1988-01-13
Abstract: The sealing ring serves to produce frictionally locking, pressure-tight connections of screwed pipe couplings to thin-walled pipes. The sealing ring is slit in a step-like manner or only partially and makes it possible to adapt its internal diameter to the external diameter of the pipe without its parts which transmit the bracing forces being deformed plastically. A plastic deformation, which effects a pressure-tight connection between the braced-in pipe and the screwed pipe coupling, takes place only in the region of the step of the step-like slit or in the non-slit part of the sealing ring. If vibration forces act on the braced-in pipe, then these are transmitted essentially by those parts of the sealing ring which are only elastically deformed. The plastically deformed parts of the sealing ring are thus not subjected to any further plastic deformation, with the result that the surface pressure on the sealing surfaces is not reduced and the sealing action is maintained.
Patent DE-3801850-A1 (DE)
Inventor: KRENKEL BERNHARD DR
IPC: D21F3/02
Filed: 1988-01-22
Abstract: Such press bands have, at least on their outer side facing the fibre web or the felt or felts, cavities and/or depressions for the removal of liquid which are produced by pouring a free-flowing mixture of a pre-polymer onto a continuous reinforcing woven belt and bonding it to the belt. Since the outer side of a press band coated in this way is smooth while the inner side of the band possesses the desired cavities and/or depressions for the removal of liquid, in order that the press band can be used in a wet press it must, after removal from the casting mould, first be inverted, a procedure which, especially in the case of small band diameters, is very difficult and requires a great deal of effort. 
<??>The invention avoids this disadvantage by arranging that, in order to manufacture the press band, the reinforcing woven band is led round one of at least two rolls which are arranged at distance in parallel one above the other or one beside the other and is coated, by means of at least one nozzle, on the outer side of the band or the inner side of the band or on both sides of the band with the free-flowing pre- polymer mixture.

Title: Snap-action switching element
Inventor: POSCHET KLAUS DIPL ING
IPC: H01H13/28
Filed: 1988-03-07
Abstract: In the case of known snap-action switching elements, the problem arises of the position of the changeover points (switching point and switching-back point) being heavily influenced by contact erosion. The snap-action switching element has a snap-action spring arrangement (8) with two mutually opposite toggle levers (10, 11), one (12) of whose ends is supported in a mounting (13) fixed to the housing, and whose opposite end is supported in a lever holder (15) on the contact link (3), the toggle levers (10, 11) being prestressed with respect to one another at their outer ends (14) by a tension spring (16). The operating plunger (9) acts on the tension spring (16) so that the relative position of the operating plunger (9) with respect to the changeover point of the bistable snap-action spring arrangement (8) is always constant, irrespective of contact erosion. The snap-action switching element is used, for example, as a limit switch. <IMAGE>

Filed: 1988-04-25
Abstract: In the method or the device for cutting and lining tunnels, shafts or the like of elongated structures, the driving is effected by means of a shield or cutter driving device. Here, the shield tail or the cutter tails (24) at the same time serve as outer formwork for the cast-in-situ lining, i.e. for producing concrete sections (28, 30, 32). In order to prevent the hollow space between the cast-in-situ lining (26) and the soil (12) from being incompletely filled after driving of the cutters, the tail of the shield or cutter driving device is divided into individual parallel strips (24) arranged at a distance from one another and supporting the soil (12), so that the spaces between the strips in the form of ribs are filled with concrete when the cast-in-situ lining (26) is being concreted. After the driving of the shield or the cutters, the spaces between the ribs are filled with concrete. <IMAGE>

Abstract: A safety rotary switch for electrical apparatuses, especially for electric cookers, consist of a rotary knob (3) which is connected to a bolt (18) and of a rotating sleeve (31) which is mounted on the bolt (18). In order to make it impossible for children to turn it on, especially for turning on hot plates on electrically operated cookers and ovens, the rotary knob (3) can be moved in the axial direction relative to the rotating sleeve (31) against the force of a spring (17) and can thus be moved into a rotationally fixed connection to the rotating sleeve (31). A driver latch (4) is mounted in the rotary knob (3) such that it can rotate about a shaft (27) and is spring loaded (13). A collar (34) of the driver latch (4) can be moved into contact against a collar (35) of the rotating sleeve (31). The collar (34) can be inserted into an annular groove (36) in the rotating sleeve (31). In consequence, it is possible to produce a positively locking connection between the toothed rim (5) of the rotating sleeve (31) and the toothed segment (33) of the driver latch (4), (sheet 1).   <IMAGE>
