Title: Concealed wall junction box for wiring installations - has hinged sides for adjusting the box height composed of parallel strips with flexible film hinge
Inventor: SAUER WOLFGANG ING GRAD
IPC: H02G3/12
Filed: 1975-12-10
Abstract: The junction box (1) is typically an injection moulding, and comprises a base (4) with side walls (5). These walls are composed of parallel strips (6,7) of which the ones (7) farthest from the base are hinged (8) to the topmost vertical strips (6). The hinge is pref. part of the moulding in the form of a flexible film. For a low profile box the hinged parts (7) may be bent to latch under the top vertical strips (6), or they may be cut off. For maximum depth the hinged parts are bent into the vertical position and lock together with moulded fasteners (11,12) at the corners. The hinged parts may have slots and holes (13,14) which serve to marshal cables together, and when cut off may still be employed for this purpose.

Title: Link for heavy duty chains for ships - uses electron beam or plasma arc welding for elliptical bridged link
Inventor: TAKAHASHI SOROKU
IPC: B21L11/14
Filed: 1976-09-24
Abstract: Links for heavy duty chains used by ships or in off-shore oil well drilling rigs can be made with increased strength by the use of electron beam or plasma-arc welding. A steel bar is first bent to form an ellipse with the joint lying on the minor axis of the ellipse. A bridge piece with its ends shaped to match the curved surface is then placed in position. The joint is then welded with an electron beam or plasma arc which fuses the ends of the bar to each other and also fuses the end of the bridge piece to the bar. Using an electron beam or plasma arc, avoids the formation of an excessive weld bead, which would have to be removed before joining on the next link.

Title: Fertiliser and soil conditioner prodn. - by steam-treating and low-temp. drying of comminuted tree bark
Inventor: UFHEIL EGBERT
IPC: C05F11/00
Filed: 1976-10-01
Abstract: In the prodn. of a natural humus-former and fertiliser from comminuted tree bark, the comminuted bark is subjected to a steam atmos. at 70-90 degrees C. and is then dried at lower temp. to a moisture content of is not 30%. Pref. the bark is first pre-comminuted, then dried at 90 degrees and comminuted to the finally required fineness. The steam treatment renders the bark more susceptible to composing processes, and destroys pathogenic, organisms without adversely affecting desirable bacteria, enzymes and the flora of the bark, so that biological activators are not required for the subsequent composting process. The composting (or rotting) process can take place after application to the soil, in which case it may be complete within ca. 2-4 months.

Patent DE-2651427-A1 (DE)
Title: Electrophotographic copying onto sheet with fine surface indentations - giving high resolution of final image obtd. by toner transfer
Inventor: BESTENREINER FRIEDRICH DR
IPC: G03G7/00
Filed: 1976-11-11
Abstract: Method consists of forming an electrostatic charge image on the photoconducting recording layer of an intermediate (temporary) recording sheet, colour with toner, then transferring the resultant toner image to the final recording sheet by direct contact and then, after the temporary sheet has been removed, fusing the final image on the latter sheet. The final recording sheet has a large number of small depressions distributed as a lattice over its surface. Pref. the lattice pitch of the depressions is smaller than the desired image resolution. The depressions may be conical in shape or parabolic. The small depressions concentrate the image-forming particles in a very large number of small groups or points, which reduce the coarseness of the image and lead to a high degree of resolution. It is thus possible for an electrophotographic image producing process to achieve a degree of resolution comparable with that of photographic or lithographic reproduction.

Title: Modification of polymer surfaces by electron bombardment - using low pressure gas discharge plasma and coated electrodes
Inventor: KREISELMEIER HANS-GERT DR
IPC: H01T19/00
Filed: 1976-11-12
Abstract: Modification of surfaces of polymers, e.g. textile fabrics or fibres, or films is by electron bombardment in low pressure gas discharge plasma in wich the polymer is passed across or between negatively charged sheet electrodes. These are shielded on the other side by parallel earthed metal plates, and coated on the polymer side with an opt. conductive material pref. different from the electrode itself. Distance of the polymer material from the electrode is greater than the dark spaced formed over the electrode. Method may be used for treatment of polymer surfaces to improve hydrophilic, adhesion or dyeing properties, and formation of free radicals to allow grafting. Equipment costs are much less than for electron accelerators, and precautions required in use are reduced. Positive ions discharged from the electrodes release sec. gamma-electrons from the coating, which are accelerated across the dark space below impact with the polymer. Treatment times are reduced to a few seconds. Activation, grafting and opt. monomer formation can be carried out simultaneously.

Title: Continuous current outlet strip with channels for plugs - are embedded in insulating strip and have channels widened at socket points
Inventor: POELLET WILFRIED
IPC: H01R25/14
Filed: 1977-02-09
Abstract: The combined current conductors and sockets take the form of pairs of rigid contact bars (5, 6, 7). They are placed in an insulating strip with insertion channels (2, 3, 4) between the bars extending over the whole strip length so that they are difficult to touch. The corresponding plug can be inserted into the channels to contact the bars without the need for rotation. A shaped wire can be inserted into the central channel to make the earth connection more accessible. At plug insertion points the channels are widened to larger rectangles; the contact bars are here springily shaped in semicircles, and the earthed plug wire is fastened in the central channel by screws.

Title: Oil burner pumping system - has air purging valve in control valve bypass passage between pump and burner nozzle
Inventor: ERIKSON ROBERT W
IPC: F04C15/00
Filed: 1977-04-25
Abstract: A pump has an inlet communicating with a fuel source, and an outlet which communicates with a control valve for regulating the pressure of the fuel supplied to the burner nozzle. High pressure fuel is pumped into the main valve chamber through a first outlet passage leading from the pump. A second outlet passage leading from the pump to the nozzle passage by-passes the control valve assembly so that air may be purged from the system when the pump initially is started. An air purging valve within the second outlet passage is movable for blocking fuel flow thrugh the passage during normal operation of the pump and for opening the second passage when the pump is initially started. The purging valve is operable manually or it may be operated automatically.
