Abstract: 1446498 Injection moulding machine control BRITISH INDUSTRIAL PLASTICS Ltd 26 March 1975 [19 June 1974] 27300/74 Heading B5A [Also in Division G3] In an hydraulically operated injection moulding machine having a variable speed hydraulic drive including a variable speed D.C. motor, and an electrical control system therefor arranged to vary the speed and torque of the motor directly in accordance with the hydraulic requirements of the machine throughout a moulding cycle, the control system includes means operable to sense the armature current of the motor and to generate a signal therefrom, together with programming means operable to cause the armature current signal to assume primary control of the machine at a preselected time and for a preselected period in the moulding cycle. Means may also be provided for sensing the speed of rotation of the motor and producing a signal which is used during the screwback part of the moulding cycle to maintain the screw rotation speed and melt condition sensibly constant. If the armature current signal falls outside pre-chosen upper and lower values a signal is generated to vary the temperature of the injection cylinder to bring the melt viscosity between corresponding limits.

Abstract: Digital exchange stations linked by earth satellite operate in a coordinately controllable time division switching and communication network system relative to externally attached telephone and data trunks. Modular switching equipment operating in coordination with satellite frames establishes and releases connection paths to trunk stores which interface with time and space domain channels of the system. Circuits through the system utilizing these paths are termed virtual connections because in different frames a circuit may be completed through different channels or even blocked under certain conditions. Telephone speech is converted between analog and digital forms relative to modular groups of 96 ports. Digital switching (slot interchange) equipment serving up to four groups (and cycling in coordination with satellite time division frames) cyclically completes local (intra-station) connections between ports and segments of toll (inter-station) connections between ports and locations in the trunk stores. The trunk stores comprise separate sections for system traffic bound to and from ports of the respective station. A duplicate arrangement of subsections in each section is alternately filled and emptied in successive frames; enabling the station to maintain continuity of communication relative to the system in successive frames. The 192 bit spaces of each location are filled in one frame and emptied in the next frame. Groups of 96 outbound locations are "virtually" associated for transmission with groups of 48 time division transmission channels of said facilities. The association operates by a process of selection termed voice activity compression (abbreviated VAC) based upon activity information developed at the port interface and carried through the switching equipment in positional association with trunk locations. The VAC process assigns only locations (virtual channels) containing activity to up to 46 of the 48 time channels, eliminating any excess of active virtual channels (over 46) in a selective order of priority. VAC mask information transmitted in a separate one of the 48 time channels indicates the virtual-to-real (96-to-46) assignment for the respective group in the respective frame. A bit in the mask for each virtual channel of the group indicates the assignment or elimination of the respective virtual channel. Assigned channels are transmitted in the time order of respective mask bits. Establishment of virtual connections is restricted system-wide by tables stored in the stations. These tables are subject to external modification and may contain path exclusion information enabling the system to remain effectively operational with inoperative elements.

Abstract: Apparatus for the capacitative measurement of the surface level of a fluid medium in a vessel comprises a probe mounted to provide a capacitance between itself and the surface, the probe being connected into one of two RC-circuits, respectively connected to opposite ends of a secondary winding of a transmitter, the primary winding of which is in a resonant high-frequency generator circuit. The two RC-circuits are earthed and respectively connected through rectifiers to the inputs of a differential amplifier, the output of which provides an output signal corresponding to the capacitance between the probe and surface level. The RC-circuit associated with the probe comprises a parallel manually adjustable capacitor and a capacitance diode arranged for the remote adjustment of the RC-circuit. Where there is a substantial separation of the probe from the RC-circuits a two-core high-frequency cable is used with one core connecting the probe into the associated RC-circuit and the other core connecting an insulated point on the probe to the other RC-circuit. A simple, sensitive apparatus, unaffected by temperature variations is thereby provided.

Abstract: The present invention relates to an electric connector member to supply electrical energy into an electric igniter of the type which includes a priming charge ignitable by heat generated when feeding an electric current through the resistive element of the igniter and which igniter must be protected against accidental ignition caused by electromagnetic or static electricity which may enter into the igniter through the feed wires. Instead of providing the igniter itself with a high frequency filter, which requires a large space, the connector member is provided with such a filter (16, 17). This makes it possible to reduce the outer dimensions of the igniter to a great extent with the protection against accidental ignition maintained. Further the need to provide each of the igniters with a specific high frequency filter, designed for the expected interference condition in the actual application, does no more exist.
