Abstract: A capping system in combination with a container having a mouth and a wall segment disposed proximate to the mouth is provided. The capping system includes a cap having a bottom for selectively covering the mouth, a jacket extending from the bottom, and a guarantee ring disposed at a distal edge of the jacket. At least one cam extends from an outer surface of the wall segment, is at least partially overlapped by the guarantee ring, and applies a force on the guarantee ring when the cap is rotated a predetermined distance relative to the container to at least partially sever the guarantee ring. The guarantee ring includes an overlapping region extending over the cam that provides clearance for the cam when the cap is initially installed on the container to prevent deformation of the guarantee ring during the installation.

Abstract: Polyesters such as polyethylene, polypropylene and polybutylene terephthalate are made from melts of precondensates of polyesters by first conducting vapors comprising precondensate components distributed in the form of an aerosol through a polycondensation reactor in which precondensate components are deposited on the reactor wall and in an outlet chamber of the reactor on a separator. Then the deposits are conducted to the unstirred discharge sump. Upper layers of the discharge sump are continuously recirculated in the stirred reactor area and thus subjected to reconversion and further polycondensation.

Abstract: The invention relates to a method and a device for producing polyesters such as for example polyethylene terephthalate, polypropylene terephthalate and polybutylene terephthalate from precondensates. According to said method, vapors comprising precondensate components that are distributed therein in the form of an aerosol are guided through a polycondensation reactor in which precondensate components condense on the reactor wall and on a separator in an exit chamber of the reactor. The condensates are guided to the unstirred discharge sump and the upper layers of the discharge sump are continuously recirculated into the stirred reactor area thereby subjecting them to reconversion and additional polycondensation.

Abstract: A self-adaptive voltage regulator for a phase-locked loop is disclosed. The phase-locked loop includes a phase detector, a charge pump, a low pass filter, and a voltage control oscillator, wherein the low pass filter inputs a control voltage to a voltage controlled oscillator for generation of an output clock. According to the method and system disclosed herein, the self-adaptive voltage regulator is coupled to an output of the low pass filter for sensing the control voltage during normal operation of the phase-locked loop, and for dynamically adjusting the supply voltage, which is input to the voltage controlled oscillator in response to the control voltage, such that the phase-locked loop maintains the control voltage within a predefined range of a reference voltage.

In the blade connector, to realize high-current contacts in the same grid dimension, one or more blade contacts are respectively allocated--via a blade body to press-in pins residing perpendicularly in a row, and in the spring clip one or more spring contacts are allocated-via a spring body--to press-in pins residing perpendicularly in a row, whereby the number of the spring contacts is equal to or greater than the number of blade contacts.

Abstract: The present invention relates to a method for making contact with a multipole female strip connector for plug connections with coaxial connecting cables. In order to simplify the method and to save tools, a multi-row female strip connector is split into plastic disks, one side of the disk having insulation-piercing terminals which are arranged one behind the other and are connected to contact springs, and the other side having correspondingly formed, overmolded pressure pieces. The disks are held spaced apart in a pressing tool by means of corresponding press-in pins which have a force fit. Coaxial connecting cables, which are cut to length and at whose free ends the outer insulation and the shield mesh have been removed over a predetermined length, are pushed into these disks, which are preassembled spaced apart. When the disks are pressed together, the pressure pieces press the connecting wires into the insulation-piercing terminal.

Abstract: The present invention relates to a method for making contact between a multi-pole socket connector for plug-in connections and connecting wires. To simplify the method and economise on tools, a multi-row socket connector is split up into plastic plates, one side of the plate holding insulation piercing connecting devices and contact springs connected thereto, and the other side having correspondingly shaped integrally extruded pressure members. The plates are held at a spacing in a press tool by corresponding press-in pins having an interference fit. Connecting wires cut to length are inserted into these plates preassembled at a spacing. The connecting wires are pressed by the pressure members into the insulation piercing connecting device when the plates are pressed together.

Abstract: An arrangement for connection of wiring backplanes and module circuit boards wherein individual contact passages arranged in a housing are surrounded by electrically conductive shielding plates that are connected to contactings that carry shield potential. They are attached in the intermediate grid both at the backplane side as well as at the assembly side, and are charged with a corresponding potential. In order to create a connector arrangement for extremely high transmission frequencies and good transmission properties, terminal ends of spring elements of the sheet metal shielding compartment and terminal ends of the spring elements of shielding plates of the contact passages abut with a contacting layer of precious metal at the backplane side. Both the spring elements of the shielding plates arranged perpendicular to the wiring backplane as well as the spring elements of the shielding compartment proceeding perpendicular to the wiring backplane are corrugated.

Abstract: The invention is directed to a plug-type connection composed of blade connector and spring clip, whereby the individual contact passages are surrounded by electrically conductive shielding plates that are connected to shield contactings carrying a ground or shield potential. The shield contactings are to an intermediate shielding grid system located both at the backplane side and at the circuit board or module side. In order to achieve an improved interconnect passage width between the contact blades and the shield contactings arranged in the intermediate grid, the electrical connection between the connector or spring clip and assembly printed circuit board ensues on the basis of pressure of spring-like bent terminal ends which flatten onto contact surfaces on the assembly printed circuit board.
