Patent DE-2819121-A1 (DE)
Title: Controlling temp. distribution in glass-melting furnace - using multiple electrodes with varying extents of bath penetration
Inventor: BANSAL BIHARI
IPC: C03B5/027
Filed: 1978-04-29
Abstract: When melting thermoplastic material, partic. glass, by heat developed by the passage of electric current between immersed electrodes, the fusion zone between batch and melt is controlled by using electrodes which penetrate into the melt to differing extents. These penetration depths may be varied when the compsn., resistivity temp. relationship, or IR absorption characteristic of the feed changes. In modification the power supply to the more deeply immersed electrodes may be increased, and the charging pattern may be varied to control the height of molten material adjacent to the wall above the uppermost electrodes. By controlling the shape and stability of the fusion zone the glass quality is improved and electrode and furnace life are extended. The arrangement makes it possible to have a temp. differential between the central and peripheral regions.

Title: Accumulator electrode plate handling system - supports pair of plates from underneath after picking up to relieve lugs of load
Inventor: STENGERT GUENTER F E ING GRAD
IPC: H01M4/21
Filed: 1978-06-29
Abstract: The plates are cast in pairs in a common plane with protruding lugs at opposite edges, by which they are picked up and transported upright for further processing. After picking up and swinging into the vertical position, the plates (4) are supported from underneath, and lifted until the lugs (5) are relieved of load. Where the plates are first deposited in an overlapping pattern and then lifted by racks on lifting tackle, this tackle can have supporting arms (6) extending vertically downwards. After the plates have swung down on the racks (2), these arms are swung up into the horizontal position, so as to lift the plates but without the lugs moving completely clear of the rack teeth.

Patent DE-2856921-A1 (DE)
Inventor: BERGGREN JAN-CHRISTER
IPC: C10J3/56
Filed: 1978-06-22
Abstract: A method and an apparatus for carrying out, at least two fluidized beds (4, 5), different chemical and/or physical processes between a heavier medium and two or more mutually different, lighter fluidizing media (F1, F2), for example combustion and gasification of solid fuel by means of air and water vapour, respectively. The beds are disposed spaced from each other but with an open communication between them at their lower ends and the one fluidizing medium (F1) is utilized for circulation of the heavier material (H) between the beds. This one fluidizing media (F1) is blown in at the open communication such that it does not mix with the other fluidizing media of the beds and the fluidizing media are led off from the beds in separate paths (16, 19).

Title: Reinforced soldering tag for flexible printed circuit board - formed from folded over strip extending from notch in edge of board
Inventor: STUMPF HEINZ
IPC: H05K1/11
Filed: 1979-01-15
Abstract: The solder tag (5) is joined to the circuit board (1) by a narrow strip (3) projecting from a notch (2) in an edge of the card. The reinforcement is produced by extending the strip beyond the first eyelet (5) and forming a second eyelet (7) at the end of this extension (8). The printed conductor (9, 10) extends all the way along the strips (3, 8) and forms circles round the eyelet positions. By folding back the extension (8) at a mid-point position (6) the two eyelets are sequentially brought into line to give the reinforcing. The proposed method eliminates the need for inserting a separate component into an eyelet to provide the required extra strenght. The two eyelets (5, 7) and connections (9, 10) are produced at the same time as the conductor pattern is etched on the card.
Patent DE-2909923-A1 (DE)
Title: Flanged joint for glass tubes - uses two channel section flanged rings each with internal flange to retain sealing ring
Inventor: HERMANNS HORST
IPC: F16L23/032
Filed: 1979-03-14
Abstract: The method forming a flanged joint between two glass tubes (13, 14) which have shoulders (15, 16) at their ends, uses two flanges which have clearance holes (9) for securing screws (22). This enables a sealing ring (21) to be clampled between the shouldered ends. Each flanged ring is made from material which is bent into s U section around the outside, this ensuring sufficient stiffness for the bolts, which pass through this region. The inner wall of this U section is formed by a double thickness of material with the inner layer bent over to retain a sealing ring (18).

Metal (I) is pref. W; and metal (II) is pref. in the Pt gp., and is esp. Ir. The sintered material pref. contains 5-50%, (25%) coated particles (I,II) and 50-95% (75%) uncoated particles (I). Particles (I,II) are pref. made by dipping particles (I) in a soln. contg. metal (II), followed by drying and heating, then mixing the particles with uncoated metal (I), pressing and sintering. The prod. is used esp. as a dispenser cathode in election tubes. The electronic work function is reduced in comparison to conventional materials, so the cathode current is increased at a given temp. Lower cathode temps. can be used to increase cathode life; or higher currents can be obtd. at the conventional operating temp.

Title: Measuring lorry load wt. without fixed weighbridge - using hydraulic cylinders raising chassis w.r.t. suspension and measuring pressure
Inventor: DOESSELMANN ARNOLD
IPC: B60P5/00
Filed: 1979-06-20
Abstract: The hydraulic system for determining the load wt. of lorries eliminates the time-consuming procedure of driving the vehicle being weighed to a fixed lorry weighbridge and enables weighing to take place almost anywhere. Cylinders placed between the chassis and axles of the vehicle enable the chassis to be lifted off the suspension. A pressure measurement device placed between the input pipe between the pressure control valve and the pressure source is calibrated in units of wt. Double-action cylinders are used. They are connected to the control valve via a return pipe as well as the input pipe. The hydraulic reservoir is connected to the control valve via the pump and directly via the return pipe.

Title: Single screw extruder - in which characteristics of screw and grooved barrel liner are covered by equation to minimise wear
Inventor: GRUENSCHLOSS EBERHARD DIPL ING
IPC: B29C48/395
Filed: 1979-09-20
Abstract: Solid particles are processed in a single screw extruder with a conventionally grooved barrel (longitudinally or spirally) to prevent the material from rotating with the screw. The compression of the material produces a redn. in vol. governed by the equation (tan A x tan B)/(tan A + tan B) x Q x p=(tan C x tan D)/(tan C + tan D) x Q1 x p1 in which A is the screw lead angle, defined by tan A equal to Ss/(pi x d) in which Ss is the lead angle and d is the outside dia. of the screw. B is the lead angle of the grooves, defined by tan B equal to Sz/(pi x d) where Sz is the pitch of the grooves. Q is the free flow path area projected axially and equals Qs + Qz where Qs and Qz are respectively the flow path areas of the screw gap and grooves. p is the specific gravity of the material. Any axial point 1 on the extruder is characterised by known or preset values of C, D, Q1 and p1, and these values can change along the extruder axis. There is minimal wear at the end of the conical grooves. Throughput can be calculated in advance and is high. Energy use is efficient and there is minimal cooling at the grooves.

Title: Ski binding with swivelling sole holder - is operated by spring system with housing, counter bearings through hand opening lever
Inventor: RICHERT MANFRED ING GRAD
IPC: A63C9/08
Filed: 1979-10-09
Abstract: The ski binding has a sole holder which swivels out to release the ski boot held by spring tension in the closed position. The spring operates, together with a housing, through a spring cage supported by a first counter bearing and actuates the closing catch with one end only when the spring cage has been transferred through a hand opening lever. The two counter bearings (14,15) are positioned on a movable change-over counter bearing which by successive swivelling down of the hand opening lever (11) move alternatively into first and second positions in which either the first or the second counter bearing are supporting the spring cage. During the transfer of the change-over counter bearing from a second to a first position the hand opening lever (11) during downward pressure moves the spring cage (13) into the closed position.
