Title: Induction hardening of adjacent steel surfaces - using a sequence of heating and cooling cycles
Inventor: HONOLD JOHANN
IPC: C21D1/10
Filed: 1975-01-10
Abstract: Process for the induction hardening of steel surfaces located at an angle to each other, esp. the end and peripheral surfaces of cylindrical or prism-shaped parts, by heating into the austenite range and quenching to below the martensite temp. The novelty is that the surfaces are induction hardened in a time sequence. A pref. process consists of heating one surface to form austenite followed by cooling down to the pearlitic region but above the temp. of martensite formation; the second surface is then heated while the first surface is still above the martensite range and the two surfaces are then quenched. Inductors possessing a complex shape are not required.

Title: Thermoplastic hose extrusion - with divergent cooling air nozzles in taper mould after cone-shaped extrusion
Inventor: HERRINGTON FOX JOHN
IPC: B29C48/90
Filed: 1975-01-22
Abstract: Hoses are extruded from thermoplastic foil material through a divergent conical die with a central air inlet. A stack of cooling rings forms a divergent mould through which cooling air escapes through channels at an angle of 50 degrees-150 degrees (100 degrees-150 degrees) to the conical surface. After solidification, the hose is folded flat and extracted through pairs of rollers. This results in a greater uniformity of the wall thickness of the extruded hoses. The resin is kept clear of the mould as long as it is not solidified.

Title: Force fit driving-in tool esp. for bolt - generates electromagnetically controlled mechanical stress wave which acts on bolt end
Inventor: LEFTHERIS BASIL P
IPC: B25C1/06
Filed: 1975-08-25
Abstract: The bolt-driving tool provides a force-fit for the bolt in a hole whose diameter is smaller than that of the bolt. The tool generates electromagnetically a controlled mechanical stress wave which acts on the bolt end. The mechanical stress wave has a high particle velocity and is controlled by a conditioning unit which regulates the intensity and duration of the high-speed stress wave in such a way that during a considerable proportion of the wave's duration a high stress level is maintained. The conditioned stress wave brings about a contraction of the bolt at right angles to the direction of propagation of the wave. The wave is reflected from the far end of the bolt in order to bestow a high speed to that end and enable it to overcome any frictional forces between the bolt and the walls of the reception opening.

Title: Functional controller for monitor sensing cuts in conveyor belt - has regular signals triggered by cut sensor producing alarm in case of defect
Inventor: LACHMANN HANS-PETER DR ING
IPC: B65G43/02
Filed: 1976-01-31
Abstract: The procedure is for functional control of a checking equipment for confirming longitudinal cuts in a conveyor belt. The belt is provided with at least one longitudinal cut. The longitudinal cut regularly initiates a signal by the cheking equipemtn which is received by a switch link. The switch link and the predetermined cut in the belt and the checking equipment are so coordinated that a signal released by the checking equipment and initiated by the predetermined longitudinal cut in the belt does not activate a switching action. The switch link is so programmed that it will produce an optical or acoustic signal or operate a switch in the case of defective functioning of the checking equipment. Instead of one cut, a number of longitudinal cuts are spaced a predetermined distance apart along the belt.
