Title: Furniture hinge
Inventor: SCHMID GUENTER
IPC: E05D3/06
Filed: 1983-05-05
Abstract: The invention relates to a small-size furniture hinge suitable, above all, for glass doors and having an opening angle of more than 90 DEG . The hinge has four partially intersecting hinge levers (9, 10, 17, 18) and seven pivot pins (11, 12, 19, 21, 22, 23) which form two four-bar mechanisms. In the closing position, the door hinge part (3) is located freely with respect to the wall hinge part (4) and the door pivot pin (19) of the first door hinge lever (17) is arranged in front of the wall pivot pin (11) of the first wall hinge lever (9). The first door hinge lever (17) extends essentially linearly away from its door pivot pin (19), its lever arm remote from the door is shorter than the lever arm near the door, and it terminates approximately in the region of the first wall hinge lever (9) which, in the closing position, extends with its main extension direction essentially parallel to the door hinge part (3). In the closing position, the wall pivot pin (12) of the second wall hinge lever (10) is arranged approximately at the same depth as the pivot pin (22) connecting this lever to the first door hinge lever (17). <IMAGE>
Patent DE-3317259-A1 (DE)
Title: Control valve
Inventor: SANDAU HARTMUT DIPL ING
IPC: F15B21/0427
Filed: 1983-05-11
Abstract: The control valve (11) serves to heat a flow of pressure medium and to keep its temperature constant. The pressure medium is heated by restriction at a spool (22) and if need be at a pilot valve (44) arranged downstream of the spool (22). A thermal sensor (54) controls an electromagnet in such a way that this electromagnet, via its plunger (61), preloads the spring (58) of the pilot valve (44) up to the opening pressure and presses the valve body (43) onto its valve seat (42) if the operating temperature is not yet reached. If this is the case, the pilot valve (44) is opened and the restriction of the pressure medium at the spool (22) is reduced. The pressure medium now flows via a bypass connection (50), as a result of which the flow resistance during neutral circulation is substantially reduced. Rapid relief of the control valve (11) is possible, which also results in lower energy losses and no overstressing of the hydraulic unit. <IMAGE>

Patent DE-3340340-A1 (DE)
Title: Film welding unit, especially for domestic purposes
Inventor: BARTH ANTON
IPC: B65B31/06
Filed: 1983-11-08
Abstract: The invention relates to a film welding unit, especially for domestic purposes, with a pump, from which at least one air duct extends, which includes a connection piece which can be inserted between two films, for example of a film bag. In a unit of this type, the danger of dirtying the air ducts and the pump is to be reduced and opportunities for cleaning are to be improved, in particular. It is proposed to achieve this object by designing the air passages which form the air duct so as to be removable, in part at least, from the rest of the unit. This has the advantage that these air passages can be detached to permit cleaning of the electrical components arranged in the rest of the unit, such as the drive motor of a pump. The pump is also preferably removable from the rest of the unit. <IMAGE>

Title: Expanding dowel having an anchor bolt and expanding shell
Inventor: FROEHLICH PETER
IPC: F16B13/06
Filed: 1983-12-21
Abstract: The expanding dowel, which consists of an anchor bolt (10) and essentially shell-shaped expanding elements (20), has recesses (14) which are arranged in a distributed manner on the anchor bolt (10) around the circumference and have cut-outs (16), which are connected to said recesses (14) towards the rearward end region (12), for the expanding elements (20). While the base (15), which is shaped like a conical sheath, of the recesses (14) approaches the outline surface of the anchor bolt (20) towards the front end (11), the base (17) of the cut-outs (16) runs parallel to the axis. The expanding elements (20) have overlaps (21) and are elastically deformable in the radial direction. Cross-sectional changes in the drilled hole in the retaining material, which occur in the course of time, can thus largely be compensated for. <IMAGE>
Patent DE-3406725-A1 (DE)
Title: Method and machine for producing and filling bags
Inventor: AREGGER BEAT
IPC: B65B9/06
Filed: 1984-02-24
Abstract: To produce the bags, two tapes (15, 16) of a sealable material are guided between two rotating sealing rollers (10). Three edges of the bag (19) are first sealed, after which a metered quantity of filling material is introduced from a filling material container (3) through the edge of the bag which is open at the top, and then the bag is fully sealed. To permit production of bags (19) of any size within a certain range, the distance between the axes (17) of rotation of the sealing rollers (10) can, with simultaneous replacement of the latter, be changed at will within a certain range (18). The sealing rollers (10) are driven via worm gears (30, 31), the worms (30) of which are situated on a common drive-shaft (29). As the bearing blocks (20, 21) of the sealing rollers (10) can be jointly adjusted by a single adjusting wheel (24), conversion to another bag size can be made quickly and without difficulty. <IMAGE>

Patent DE-3414554-A1 (DE)
Title: Method and circuit arrangement for cancelling crosstalk and/or echo signals
Inventor: SCHENK HEINRICH DR ING
IPC: H04B3/23
Filed: 1984-04-17
Abstract: In an adaptive crosstalk and/or echo cancelling circuit located on the four-wire side in parallel with a hybrid circuit and having a variable filter and a cancellation signal logic element, the cancellation signal is formed depending on the - if necessary averaged - difference between the discriminator output signal formed after the signal cancellation and following adaptive signal equalisation and the discriminator input signal, by setting the filter coefficients in the case of a significant - if necessary averaged - difference between the discriminator input signal and the discriminator output signal according to the cancelled received signal and in the case of an insignificant - if necessary averaged - difference according to this difference. A controlled amplification is first carried out after the crosstalk and/or echo cancellation; the adjustment signal for the variable filter obtained from the difference between the discriminator output signal and the discriminator input signal - and, if the filter adjustment signal corresponding to the cancelled received signal is derived from the cancelled and amplified received signal, this adjustment signal also - is multiplied by a factor reciprocally proportional to the amplification factor. <IMAGE>

Patent DE-3508015-A1 (DE)
Title: Anchor bolt
Inventor: SCHNEIDER JOSEF
IPC: F16B13/06
Filed: 1985-03-07
Abstract: The invention relates to an anchor bolt having a cylindrical bolt body which exhibits, at its front end, a tapering with a cylindrical portion, which tapering forms a shoulder towards the bolt body and, towards the front end, runs into a conically widening expanding cone. An expanding sleeve provided with a longitudinal slot encloses the cylindrical portion, can be expanded by axial displacement up to a collar terminating the expanding cone and can be anchored in a blind hole by means of anchoring parts projecting radially on the periphery. By special design of the expanding sleeve and of the shoulder between the bolt body and the cylindrical portion, the production of the expanding sleeve is simplified and its support on the shoulder when being driven into the blind hole is improved, without a sharp edge with a tendency to fracture being obtained at this point.

Title: Two-phase steaming process for fixing prints containing reactive dyestuffs to keratin fibres
Inventor: ROTH KURT
IPC: D06P3/82
Filed: 1985-05-21
Abstract: The fixation of reactive dyestuffs to keratin fibres and blends thereof with cellulose fibres by steaming does not always lead, in particular in the presence of large patches of fabric, to acceptable dyeing results on account of the frosting and of the tippy dyeing caused by "drying-out" of the steamer. The existing defects are removed by means of the use of a two-phase steaming process, previously unknown in the case of keratin fibres, which provides for minimum-liquor application systems for the application of the fixing alkali applied to the preprint, together with the fixation of the dyestuffs in a festoon steamer.
