Patent DE-2131500-B2 (DE)
Title: Optical coupler for waveguides - enables parallel laser light beam to enter optical conductor through conical end face
IPC: G02B6/42
Filed: 1971-06-24
Abstract: The coupler for an optical system is arranged for a boundary at which a discontinuity in refractive index occurs. A beam of parallel light is directed against the end face of the wave conductor which has a refractive index which differs from that of an envelope material forming a thin film around the centre wave guide. For waves of the dipolar type, the end face of the guide has a conical cross section with angle of incidence (EPSILON) chosen so that the resulting angle of refraction (BETA) creates an internal angle of reflection (ALPHA-K) appropriate to the total angle of reflection at the guide interface. Laser light may be used which is polarised in parallel or perpendicular modes in order to stimulate THE or TEH waves in the guides.
Patent DE-2145854-B2 (DE)
Title: Power transmission belt - overlaid with several thicknesses of rubberised fabric in single pass
IPC: F16G5/08
Filed: 1971-09-14
Abstract: Belting of trapezoidal cross section has a core of reinforced rubber and an outer covering made from strip material helically wound about the core. The winding tape is cut parallel to the warp axis of a sheet of rubberised cloth to a tape width of B where B is defined by B=KP sin alpha (where K = no of superimposed layers or thicknesses of wrapping required, P is the length of the perimeter of the belt cross section and alpha is the winding angle of the tape onto the core). For mfr. of power transmission or pulley belts, the respective overlap ensured by the stated relationship allows the desired overlay of thicknesses to be achieved by a single pass of the core through the tape winding unit. Tape cut parallel to the sheet warp axis is inherently stronger than tapes cut on a bias. Matching of the tape with the overlap pattern avoids local overlaps of tape ends which can stiffen and locally stress or crack the belt structure when flexing through pulleys.

Title: Hydraulic circuit, adjusting roll pressure in rolling mills - includes stepper motor driving servovalve controlling variable displacement pump
IPC: B21B37/62
Filed: 1971-12-13
Abstract: Hydraulic adjusting device for rolling mills has a control piston in a servo valve employed to feed hydraulic fluid to a work cylinder which adusts the roll press.; the control piston is actuated by a stepper motor, and a feedback circuit is used between the work cylinder and the servo valve. Angular motion of the stepper motor is converted into a linear motion, which adjusts the control piston, by a spindle located in a ball nut which cannot rotate so it undergoes linear motion. The servo valve adjusts a variable displacement pump feeding fluid to the work cylinder; and adjustment of the pump rotates a second spindle causing the linear motion of a second ball nut which is an integral part of a housing contg. the stepper motor. The robustness of a mechanical-hydraulic control system is combined with the accuracy of an electrical system.

Title: Locking pin for positioning terminal strip - has eccentric post projecting from end of symmetric flattened cylinder
IPC: H05K7/14
Filed: 1972-01-20
Abstract: The locking pin has a main part with the shape of a flattened cylinder and a secondary part (2) in the form of a post. The cylinder has flat sides and its cross-section is symmetric longitudinally and transversely. The post has a circular cross-section and extends beyond the end of the cylinder with its axis parallel to it. The post's axis is one half of the raster spacing used for mounting components (r) away from the axis of the cylinder. The cylinder has a transverse hole (3) whose diameter is greater than that of the post. The pin enables use of a larger raster spacing while retaining the advantages of a smaller spacing.

Abstract: A strain relief system for flexible circuits has a tapered cover laminate affixed to either side of the flexible circuit to form a cover laminate/flexible circuit assembly, with the widest portion of the cover laminate being at the point of maximum bending stress of the flexible circuit to provide a stiffer assembly at that point. A rigid stiffener having a bending radius also is affixed to either side of the cover laminate/flexible circuit assembly at the point of maximum bending stress to provide strain relief, the bending radii being laterally offset from each other so that bending in opposite directions occurs at different locations of the flexible circuit. The result is a gentle, low stress bend in the flexible circuit when subjected to regular bending.

Abstract: A body implantable electrode (20,68) includes a platinum wire or filament (28,40,46,52,70) compressed and bundled into a serpentine configuration and retained within a platinum screen (30), thus to form a highly porous electrode. The electrode body is then surface treated by vapor deposition or vapor deposition in combination with electroplating, to provide an adhesion layer (38,48,54), a texturizing layer (38,50,56), and one or more catalytic cover layers (44,58,60). The texturizing layer, which can be titanium, carbon black or aluminum, is formed with multiple nodules and depressions which substantially increase the reactive surface area of the electrode. The catalytic layer can be platinum, platinum-black or platinum followed by a layer of carbon. The combination of macro porosity and micro texture provides an electrode that promotes tissue ingrowth after implant and maintains a low chronic stimulation threshold due to its large reactive surface area in proportion to its geometric size. <IMAGE>

Abstract: The invention relates to a process for producing aroma-containing food products in which exogenously and/or endogenously formed enzyme complexes are separated from specific pure or mixed cultures of microorganisms, which develop certain characteristic flavoring and aromatizing agents. The enzyme complexes are subsequently added to an aqueous solution or suspension of a substrate. The isolated enzyme complexes are optionally concentrated or standardized beforehand under careful conditions. The mixture of the substrate and enzyme complexes subsequently undergoes biochemical rapid ripening under suitable conditions until the desired aromatizing and flavoring agent concentration is obtained. The biochemical rapid ripening is then terminated by substantial inactivation of the enzyme complexes. The ferment solution or suspension obtained and which contains the desired flavoring and aromatizing substances, can be added to basic food substances for aromatizing them.
