Patent DE-2913595-A1 (DE)
Inventor: RUTISHAUSER THOMAS
IPC: B65H29/52
Filed: 1979-04-04
Abstract: After, for example, a form (12') has been written on in a typewriter platen (32), in order to be able to convey it to a delivery magazine (76) disposed at a higher level, it is necessary for the sheet (12''), after its emergence from a conveying gap (35'), to be moved transversely to the direction of travel defined by the conveying gap. In order to make this movement possible, there is arranged next to the transport roller pair (34', 36') a toothed wheel (40'), the teeth (41') of which project above the circumferential surface of the transport roller (34'). The teeth (41') grip the sheet (12'') at its end and move it into the delivery magazine (76). In order to ensure reliability in grasping the sheet, the latter can be held against the teeth (41') by a compliantly arranged guide surface (90). <IMAGE>
Patent DE-2922040-A1 (DE)
Inventor: PANZERI CESARE
IPC: B23K9/02
Filed: 1979-05-30
Abstract: A process and an apparatus for continuously welding large high gauge sheets, according to which the position of a torch is defined by a feeler bearing on the root and on a wall of a chamfer. After carrying out a first weld line a switch means signals the end of the first line and moves the feeler to the other side of the chamfer while still dragging along the welding torch, and during its movement measuring the chamfer width at that particular level of the joint. The feeler and torch remain in the same plane parallel to the chamfer axis and contains both of them. The sensed width is then compared with stored widths, thus deciding how many weld lines have to be deposited in that layer, at the same time carrying out the second weld line with the feeler and torch adjacent the other side of the chamfer, and still arranged in a plane parallel to the above mentioned plane. The feeler is then controlled to move transversely of the joint through the same distance as the width of the weld line which shall be made in that area, this displacement caused by copying an identical movement which is an inverted reflected movement on the torch, the latter being positioned at the same distance from the feeler as the width of a weld line. A third weld line is then carried out adjacent the second one and so on for the number of lines as predetermined in advance, whereupon the feeler and torch move back to the starting chamfer wall to initiate a new weld layer.

Title: Heat treatment process for power resistor - uses plasma arc methods to change state of oxide or other insulating material to form layer with negative temp. coefficient
Inventor: STAREK BRUNO DR
IPC: H01C1/142
Filed: 1979-12-11
Abstract: The method is for producing heating and power resistor elements using plasma flame methods on the surface of the material to be treated. A non or poorly conducting inorganic material such as an oxide, nitride, boride or carbide of silicon is converted into a conducting metastable state by plasma arc heat treatment. The treatment is selective to parts of the surface and adjustable according to the requirement for temp. and voltage, these being matched to material and method parameters, e.g. the 'Redox' system. Stipulations for surface and layer materials relate to the mix of silicon nitride to silicon carbide. A non-conducting layer of aluminium oxide is required and a conducting layer of titanium oxide. One layer or layer constituent has a negative temp. gradient. The plasma process produces a grid effect of ion groupings in the material. A typical resistive material construction is a base (1) carrying the insulation layer (2), then the resistance material produced as above (3), located between copper, or similar, terminal strips (4, 4') with a corrosion resistant or protective substance (5) as outer coating.
