Title: Reduction of electric coupling in telecommunication cables - uses phase changing during stranding of cores for pairs and quads
Inventor: VOGELSBERG DIETER DIPL ING
IPC: H01B13/04
Filed: 1975-02-06
Abstract: The system is intended for reducing electric couplings in telecommunication cables. This is achieved during the stranding processes, by stranding the wire cores in two stages to pairs, or quads, and by stranding the pairs or quads into groups. The stranded units in a group will have the phase location of the core changed discontinuously so that the unit will have equal size lengths of the cores with different phase positions. The angular displacement of the phases of the cores will be summetrical about a circle. The position will represent a whole number multiple of an SZ section, which is equivalent to double the distance between reversal positions in the direction of turn.

Title: Detoxicating tobacco, cigars and cigarettes - by generating catalyst while smoking pref, achieved by adding metal nitrates of hydroxides
Inventor: BRANTL VICTOR
IPC: A24B15/28
Filed: 1975-04-28
Abstract: Detoxicating tobacco, cigars and/or cigarettes takes place by generating a catalyst during actual combustion of the tobacco, in order to lower toxic material content in combustion gas. This is pref. achieved by admixing the tobacco with either (a) metal salts of N oxyacids, esp. metal nitrate/s or (b) metal hydroxides. The additive-contg. toxicity-reduced tobaccos obtd. are specifically claimed. Catalyst generated during combustion is partic. active and smoke contains less toxic materials, esp. less NO and CO. Catalysts used include those which are unstable in isolated form. O2 released on using nitrates prevents extinguishing of glowing tobacco esp. when smoking a pipe, and obviates need for drawing pipe. Additives having an acid character adsorb or adsorb various toxic materials, esp. nicotinic acid.
Patent DE-2522708-A1 (DE)
Title: Welding transformer for connection to electric lighting circuit - uses low primary current but produces high welding current
Inventor: TELLERT FRITZ
IPC: H01F38/08
Filed: 1975-05-20
Abstract: Compensated alternating current transformer for welding appts., esp. for connecting to a lighting circuit, with completely separate prim and sec. windings and control of the welding current by tapping switches and additional prim. windings, as described in 1228730. In the present invention, the product of the (number of turns) X (cross-section) X (average conductor length) of the prim. winding is >6% larger than the product for the sec. winding, calculated in the same way. The number of sec. windings is reduced so the induction, pref. using grain-oriented material or tape-wound cores, is raised into the saturation zone of the tape so a high inductive pre-load occurs with idling current but decreases when welding current is used, improving the dynamic behaviour and power of the welding transformer. Material and wt. can be reduced, and a lower primary current employed so that a normal electric lighting circuit can be used for welding with electrodes up to 3.25 mm dia. without blowing the fuses in the lighting circuit.

The holders and connectors pref. consist of a ribbed plate with cheeks on which the roller bearings are mounted, the cheeks being joined by flexible webs; alternately, the ribbed plate may be assembled from separate links. The guide paths for the welding wires are very easy to adjust and a min. radius of curvature of 8 cm achieved, suitable for welding pipes with dia. below 1 metre.
Patent DE-2529666-A1 (DE)
Title: Coupling flange ring assembly for elastic hose - has internal, expandable metal clamp bush
Inventor: BUZZI GUENTER
IPC: F16L33/22
Filed: 1975-07-03
Abstract: A flexible hose (1) has a coupling sleeve assembly which consists of an inner and outer flange bush. An assembly block (8), made up of two identical jaws (6, 7) locates the outer flange ring (2, 3) together with the hose end (1). The inner flange ring (4, 5) is then inserted into the bore of the hose such that the radial flanges (3, 5) of the two sleeves are in contact with each other. An expansion mandrel (10) is then forced into the inner sleeve (4) so that the elastic hose material is clamped between the two cylindrical flange rings (2, 4). To increase the leak resistance of the coupling sleeve assembly, a seal ring can be placed between the axial end face of the hose and the two flange rings.

Title: Exothermic catalytic reactor - e.g. for prodn. of methane from hydrogen and carbon dioxide, recovery of methanol or formaldehyde
Inventor: SCHNEEBERGER MARTIN ING GRAD
IPC: B01J8/02
Filed: 1975-11-04

Cooling pipes pass through the annular space and the catalyst system. At least one of the feed pipes for the reactant gas discharges into the annular chamber. The reactor can be operated at its economically optimum reaction temp. whilst the housing is protected from the thermal stress associated with that temp. The reaction products leave the reactor at high temp. (e.g. 600 degrees C) and heat can be recovered economically from them.

Patent DE-2620869-A1 (DE)
Title: Rotary percussive drill tool - has radial blade and second blade vertical to outside tool endface centre point
Inventor: SCHULTE-ZWECKEL KLEMENS
IPC: E21B10/38
Filed: 1976-05-11
Abstract: Rotary percussive drilling tool consists of two hard metal cutter plates brazed into the endface of the drill head itself. One cutter blade (10) stands radially, as compared with the second (8) which is vertical to this outside the centre point of the endface of the drill tool. This raises the specific impact energy to the tool and should improve footage. By arranging one blade asymmetrically, this always strikes differing areas of the rock face and thus forms a hole face without the disadvantage of the tool repeatedly striking the same groove in the rock. More energy is converted into useful work, and this in turn reduces recoil.
Patent DE-2623453-A1 (DE)
Title: Rim for automobile wheel - has circumferential reinforcing rib and is welded to wheel disc
Inventor: BRINKMANN HEINZ ING GRAD
IPC: B21D53/26
Filed: 1976-05-21
Abstract: The rim (1) for an automobile wheel is of relatively small radial depth. The stiffness of the rim is improved by forming a circumferential depression which results in a local reduction in the thickness of the wall (4). The material from the region of reduced thickness is forced into the shoulders (5) and (6). The strength of the material in these regions (5, 6) is further increased by local rolling. The rim is then joined to the wheel disc (2) by the weld (3). The small radial depth of the rim makes possible a large air gap between the rim and the wheel disc (2). In addition, this type of rim allows the use of smaller tyres.
