Title: Optical monitor to identify splits in cine film - responds when either edge of film ceases to turn friction roller and employs light sensitive elements
Inventor: WEINKOPF HEINRICH
IPC: G03B21/32
Filed: 1976-02-19
Abstract: Each edge of the film (5) drives a friction roller (11, 11) whose movement continually interrupts a light signal; a steady signal from either side is evidence for a split film. The two light signals pass from a common source (29) through narrow channels (47, 49) to two light-sensitive elements (31, 31) (pref. photo-transistors). The signal is sent when the light encounters a reflective sector (21) of the friction wheel, and interrupted when it encounters a matt sector (22). The resulting intermittent electrical signals are differentiated, and the positive pips passed through diodes to accumulate in leaky capacitors; if either capacitor begins to lose charge, the monitor issues its warning signal.

Title: Finishing process for fibrous fleeces, esp. synthetic leathers - improves physical characteristics reducing anisotropy esp. regarding tensile strength
Inventor: MATHES NIKOLAUS DIPL CHEM DR
IPC: D04H1/70
Filed: 1976-08-18
Abstract: The characteristics of impregnated and/or laminated fibrous fleeces, esp. with a redn. of their anisotropy, is improved by stretching. During the impregnation process or during a later operational stage, the fleeces are stretched at temps. between 50 degrees C and 10 degrees C below the plasticising temp. of the bonding agent, transversely, to a degree of 10 to 100% relatively to their point of shear under tension. During stretching, the fibrous fleece is heated on one side so that the temp. on the opposite side of the fleece does not rise higher than about 80 degrees C. A fibrous fleece impregnated with a bonding agent may be first of all stretched transversely and then be allowed to relax freely. A surface layer is applied tot he fleece andit is again stretched transversely by 50% relatively to the stretch on breaking of the coated material. During the stretching operation on a laminated material, heat is applied from the surface with a coating layer. Method improves the characteristics of synthetic leathers, esp. as regards anisotropy, increasing also their softness and porosity.
