Title: Moving strip cutting device control - compares transport belt and strip speeds continually and stops cutter at excessive speed
Inventor: HALBERSCHMIDT FRIEDRICH DIPL I
IPC: B23D36/00
Filed: 1977-06-29
Abstract: The procedure is for cutting through a continually moving strip using a flying type cutting device moving synchronously with the strip during the cutting process. The speed of the strip is continuously measured, and the values obtained are used to control the cutting speed. Additionally the inherent speed of the transport belt is measured, and there is a continuous comparison between belt and strip speeds. If there is a deviation which exceeds a pre-set tolerance limit, the cutting device is stopped. To effect this process, a tacho-generator(24) is coupled to the transport belt(2), and its voltage is compared with that from the material strip(1) measurement device(18). A voltage difference exceeding the tolerance is fed via an adjustment potentiometer(26) to a trigger which sends a signal to activate a cut-out relay in the cutting unit main circuit.

Title: Lubricating friction surfaces in power transmission unit - of synthetic material, by immersing moulded parts in lubricant soln. before assembly (NL 3.1.79)
Inventor: AWAKOWICZ ERWIN
IPC: F16C33/10
Filed: 1977-06-30
Abstract: A lubricant, e.g. oil, is applied to the friction surfaces of a precision power-transmission unit, in which the power-transmission element and the bearings are (partly) formed by moulded synthetic parts, by briefly immersing (portion of) the synthetic parts forming the element or bearing in a lubricant dissolved in an easily volatile carrier liquid, to form a lubricant layer over the whole surface. The treatment takes place before the power-transmission unit is assembled. The power-transmission unit may be, e.g. the gearing of a telephone dial switch, or the control linkage for the cradle switch in a telephone. The amt. of lubricant used is small. No friction surfaces are omitted from the treatment, as may happen with manula appln. of a lubricant. The appln. of the lubricant can be precisely metered, and all friction surfaces can be treated in one operation. Lubricant is applied to surfaces which are difficult to reach after assembly. It may be sufficient to apply the lubricant to only one of a pair of friction surfaces.
