Abstract: Process for producing low energy vinyl dispersion resins which, in a plastisol, can be fused either at lower temperatures or in a shorter period of time than the normal dispersion grade resins presently employed. The new vinyl resin is characterized by being a  bimodal resin, i.e., containing large particles and small particles of polymer in a predetermined size and amount. The small particles are a vinyl homopolymer or copolymer made by a regular emulsion polymerization procedure. The large particles are a vinyl copolymer made employing a seeded emulsion overpolymerization procedure wherein the seed is either a vinyl homopolymer or a vinyl copolymer. The final bimodal resin is obtained from a blend of the small and large particle lattices by drying, such as spray drying, for example.

Abstract: This invention relates to spectacles in which are spectacle lens is connected to an individual component, for example a flange, by means of a fatening device. In the spectacle lens the two ends of a borehole are expanded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion. In addition, the flange has two further protrusions supporting themselves on the border of the spectacle lens, so that a four-point anchoring of the flange secured by the pin against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa. A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping surfaces for the connecting element and first protrusion, but the borehole widening.

Abstract: A working on the zero IF principle is disclosed which contains a feedback circuit instead of a preselector for suppressing interfering signals. The interfering signals contained in the incoming signal (FE) are separated from the useful signal by filters in the baseband. They are then reconverted to the RF value, amplified, and substracted from the incoming signal (FE) by a subtracter (S1). In the steady state, the output of the subtracter (S1) provides the useful signal, which is converted into the baseband and then fed to a signal processor (SV).

Abstract: A unitary axial multiport rotary valve capable of accomplishing the simultaneous interconnection of a plurality of conduits in accordance with a previously determined cycle, where any conduit communicates with no more than one other conduit at any one cycle step, or valve index position. The conduits to be interconnected are attached to a hollow stationary body, or stator assembly (11-13), which is comprised of three sections, or elements, each of which is cylindrical in exterior form. There are fluid flow paths in a rotating body, or rotor assembly (17, 18), which is located inside the stator assembly. The rotor assembly assumes various positions according to the cycle steps and distributes fluid flowing into and out of the valve in a different manner in each cycle step. There are spaces between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages. In one embodiment, the rotor assembly is configured such that axial forces exerted by the fluid streams are exerted equally in both directions, thereby providing a balanced rotor assembly floating between its axial restraints.

Abstract: A video display system for displaying a wide screen image having an aspect ratio, such as 5:3, greater than the standard, such as 4:3, aspect ratio of the images represented by conventional television video signals, is arranged for displaying such an image of standard aspect ratio without changing the width of the normal wide aspect raster of the display system. To this end the display system includes a signal processor which, in response to a video signal representative of a standard aspect ratio image, produces, for driving the wide aspect ratio display, a processed video signal the line periods of which each include not only the line synchronizing interval and active video interval but also a delay interval ('PAUSE') the effect of which is to determine the position of the displayed standard aspect ratio image within the width of the wide aspect ratio raster.

Abstract: An automatic/remote instrument monitoring system and method are disclosed. RF transponder units are operatively connected to and monitor one or more parameters of a remotely located instrument. The transponders include RF receivers that sample received RF signals at a low duty cycle and look for a common wake-up signal transmitted from a mobile data collection unit.

The time and frequency parameters of the transponder transmissions are varied in a manner such that the transmission signals of simultaneously transmitting transponders differ. A plurality of RF receivers in the mobile unit are respectively tuned to collectively receive the transponder transmissions, across the entire transmission bandwidth. Decoding and signal processing circuits in the mobile receiver unit identify transmitting transponders and process their respective messages.
