Title: Entrainment jets for fume extraction - allowing total air movement to be reduced esp on electric arc furnaces
Inventor: HOELTER HEINZ
IPC: B08B15/02
Filed: 1972-03-23
Abstract: Exhaust gases, degradation products etc., esp. from electric arc furnaces, are extracted with the aid of one or more extraction jets located near the centre of the extraction zone. The jet or jets can be at one point or in a circle. The jets can be dosed with additives as required to improve the accumulation or agglomeration of the degradation products in the jet. The volume of air required in the extraction zone is reduced and hence running costs are reduced.

Title: Welding or plating metals by hydrospark process - shock wave generated in water joins tubes by high speed deformation
Inventor: SCHENK HORST DIPL PHYS
IPC: B23K20/08
Filed: 1973-05-02
Abstract: In joining two tubes, one is inserted in a cylindrical anvil so that its end is pushed against a ledge in the bore of the anvil. The end of the second tube is formed into a cone, the length of the cone being the length of the weld desired (L); this tube is now inserted from the other end of the anvil so that the length (L) enters the first tube, the cone forming an angle of 6-10 degrees with the bore of the first tube. An elastic shell is then inserted in the second tube, the periphery of the shell making contact with the internal conical section. The shell is filled with water and also contains an ignition wire. A current pulse causes the wire to evaporate instantaneously and the resultant shock wave drives the conical part of the second tube onto the bore of the other tube at high velocity so that a weld is obtd. Similar equipment can be used for coating metal parts with e.g. aluminium using a sheet of Al foil.

Patent DE-2423691-A1 (DE)
Title: Sensing rollers for detecting conveyor belt damage - rollers located on swing arms which trigger conveyor stop switch
Inventor: KOPECZ KARL
IPC: B65G43/02
Filed: 1974-05-15
Abstract: A conveyor belt is monitored for damaged edges or longitudinal slots by means of sensing rollers. The rollers are carried by pairs of swing levers so that gravity or a spring load presses the roller flanges against the belt edges. Helical ridges on the roller diameters are in contact with the under side of the belt and tend to push the belt edges towards the centre line. If the belt is torn in a longitudinal direction it will overlap along the slot, thus reducing its width. This reduction is detected by the sensing rollers so that the resulting swing lever movement triggers a switch which stops the belt drive.

Title: Battery charging control cct. with timers - prevents over charging when battery has only partially discharged
Inventor: ESCH ULRICH
IPC: H02J7/00
Filed: 1974-08-09
Abstract: The charging current is cut in at a preset low battery voltage, and then switched to a reduced rate for a preset time when a higher potential has been reached. To prevent over charging the timer controlling the secondary charging phase is only switched on after the main charging current contact has been closed for a predetermined time. Preferably the closed time of this contact is a summed up and is not less than thirty minutes. Thus short term interruptions of the main power supply do not lead immediately to full charging cycles. Preferably a thyristor is operated by a positive semi-conductor voltage on the anode side. The thyristor is then in a condition to always become non-conducting when the blocking voltage appears at the gate.
