Title: Electrically melting materials with negative temp. coefficient - controlling heat input via resistance values of charge itself
Inventor: SCHADE WALTER DR
IPC: H05B3/00
Filed: 1975-08-02
Abstract: The raw material such as glass etc. gradually changes into the electrically conducting state as the temp. rises and control of the temp. is loss free in dependence of the resistance of the melt, during heating up. The resistance of the melt is registered at D.C. or A.C. current stabilisers with the aid of which the working current is so adjusted that the value of the rated resistance is kept constant. Homogeneous heating over the entire cross-section of the melt is achieved.

Patent DE-2544919-A1 (DE)
Title: Torque overload coupling for axially aligned sleeves - has diametrally opposite balls spring biased in recesses of coupled flanges
IPC: F16D43/206
Filed: 1975-10-07
Abstract: The overlead coupling comprises two relatively rotatable flanged sleeves (1, 2) pushed together axially by a spring (7). The confronting end flanges at the sleeves are separated by two diametrally opposite balls (5) held in a cage (6) and seated in shallow grooves in both parts. Each groove has two diametrally opposite recesses for the balls to transmit drive between the parts. On overlead the balls are pushed out of the recesses and travel around the grooves. Since the balls then travel at half the relative speeds of the two parts, re-engagement between the two parts does not occur until the parts have undergone 360 deg. of relative rotation. Disengagement causes a switch (9) to cut out the drive motor until re-engagement occurs.

Title: Metal, esp. iron, fibres mfr. - by evaporating metal cpd. and decomposing, in reactor provided with magnetic field, to form short fibres on moving strip
Inventor: SCHOEN HEINZ
IPC: B22F1/062
Filed: 1976-02-03
Abstract: Metal fibres are made by evapn. of a metal cpd. which is then fed with carrier gas into a hot reactor provided with a magnetic field parallel to the reactor wall. The cpd. decomposes, forming short fibres which grow on a mobile stabilising and crystallisation surface (1) to form long chains. The novelty is that surface (1) is formed by strip moving continuously through the reactor and removing the fibres. The pref. strip is nonmagnetic and preheated, esp. Cu wire fed from a coil. In the pref. appts., the cpd. and hot inert gas are fed together with the Cu wire into the top of the reactor, which is surrounded by a magnet; the Cu wire is drawn by friction rolls through a die which strips the fibres off the wire so they fall into a collector. The appts. can be used to make iron fibres from iron carbonyl, or fibres of alloys or cpds. Reliable, continuous prodn. is obtd.

Title: Yarn package tube for heat and fluid processing - is elastically flexible axially and radially to compensate shrinkage
Inventor: ENGEL ADALBERT
IPC: D06B23/04
Filed: 1976-02-24
Abstract: A textile tube, conical or cylindrical in form, and esp. of thermoplastic material, is intended for the processing of yarns and threads by heat and or fluid. The tube mantle which may be produced by extrusion blow moulding or deep drawing is covered by a series of alternate ribs and grooves, running spirally or lying along circular lines. The tube is thus, axially, and at least under the influence of heat, radially, elastically and plastically yielding, whilst retaining approximately, its sectional form. The tubes have a high degree of axial and if necessary, radial flexibility and suppleness, together with very good stability of form. They are suitable for the heat and/or fluid treatment of the yarn wound on, and are able to conform to alterations of the physical characteristics of the threads during treatment, whilst at the same time maintaining their stability and sectional form. The tubes are easy and cheap to make and have a wide range of applications.

Title: Rapidly rechargeable alkali metal-sulphur electrochemical cell - contg. dienophilic additive limiting internal resistance and reducing viscosity
Inventor: FISCHER WILFRIED DIPL PHYS DR
IPC: H01M10/39
Filed: 1976-07-24
Abstract: Electrochemical storage cell or battery based on alkali metal and S, with an ion-conducting solid electrolyte between the anode and cathode compartments, contains a dienophilic additive in the cathode compartment(s). The additive pref. has the formula R2C=CR2 (where R gps. independently are F, Cl, Br, CN or SCN) and pref. is tetracyanoethylene. The amt. used pref. is 0.1-2 mole % w.r.t. the S in the cathode compartment. The batteries are designed to cover peak loads, e.g. in conjunction with nuclear reactors. Rapid and more complete recharging is possible, since the build-up of liquid S as insulator is prevented by making the phase in the cathode compartment more mobile. The additive limits internal resistance and reduces the viscosity by breaking down the 5 chains into 3 parts, one neutral, one in the form of a negative complex and one a positively charged chain.
