Abstract: A printed circuit board which is of such a construction that patterns of electrically conductive strips and/or pads of either standard or non-standard form can be readily provided comprises a rigid board 1 of which at least the major surfaces are of electrically insulating material, which has extending through the board a multiplicity of holes 2 arranged in a pattern of rows and columns and which carries on one or each of its major surfaces a multiplicity of annular metal islands 3 each bounding a hole in the board and discrete with respect to the other annular islands. The rigid board 1 may also carry on said one or each of its major surfaces supplementary metal islands 4 and 5 each positioned between and discrete with respect to annular islands bounding adjacent holes in the rigid board. A circuit of either a standard or non-standard pattern can be formed by electrically interconnecting selected adjacent metal islands 3, 4 and 5 with local deposits of material of high electrical conductivity in such a way as to bridge the gap between adjacent islands. The local deposits may be effected manually but are preferably effected automatically using a modified computer aided design plotter or an automatic fluid dispensing machine.

Abstract: A multi-cavity valve gated injection molding system. The pneumatic actuating mechanism to reciprocate each elongated valve member (70) includes a piston (90) which reciprocates in a cylindrical opening (92) through a cylinder plate (12). A sealing bushing (56) which is mounted around each valve member (70) has a flanged portion (66) which bridges an insulative air gap (68) between the manifold (10) and the cylinder plate (12).

Abstract: 1. The invention is based on the object of providing a contactor with emergency shut-down which dissipates the switching off energy even when the supply is switched off and reduces the voltage surges occurring during switching off. 2. The invention is characterised in that a transient voltage suppression diode (7) is used to limit the voltage surges, which diode is connected in parallel with an electronic actuator (5) with which the current through the contactor coil (1) is pulsed, for the purpose of current regulation, and in that a feedback diode (8) is connected in the forward direction between the earth-side connection of the voltage suppression diode (7) and the input of the contactor coil (1), which diode ensures that the switch-off voltage surge is dissipated via a return current through the contactor coil (1) when the earth (10) is switched off. 3. The invention relates to electronic contactors with emergency shut-down having a freewheeling circuit which can be switched off and a semi-conductor component with a defined breakdown voltage for limiting the inductive voltage surges when the load circuit and freewheeling circuit are switched off. <IMAGE>

Abstract: In the radio data system (RDS), digital data which contain, among other things, a list of alternative frequencies (AF) with the same programme, from which the receiver can select a different receiving frequency when the receiving conditions deteriorate due to a change in location, are inaudibly transmitted together with the radio programme. However, the transmission of a complete AF list from the transmitter to the receiver can take up to 45 seconds and longer. To be able to switch without delay and inaudibly to alternative frequencies when the stored frequency of the master transmitter is not suitable for reception during a spontaneous programme call-up in different transmitting areas, the programme memories of the receiver should immediately provide a limited selection of suitable AFs. For this purpose, the memory content of this programme memory is empirically built up by automatically transferring alternative frequencies of the programmes radiated with the same PI code in the course of time from other memories and/or memory levels into the programme memories when the frequencies received during an operational or routine tuning of the receiver are confirmed as RDS transmitter frequencies having adequate quality of reception. <IMAGE>

Abstract: The invention relates to communications systems and concerns in particular subscriber telephone sets with push-button dialling and not only provides the facility of automatic, repeated multiple number selection with a subsequent subscriber call when the connection is established, but also, if the line is engaged, ensures automatic operation of the subscriber telephone set in cases where the signals of the automatic exchange arrive with a delay at the end of the number selection (which is a characteristic feature of operation with quasi-electronic and electronic automatic exchanges). Furthermore, in order to prevent uncontrollable seizure and overload of connection lines, the device ensures the operation of a standardised restriction of the number of repeated automatic number selections. The device is based on the principle of introduction of the operating mode with a varying start for the period of release to count the number of automatic, repeated number selections.

Abstract: A technique for packaging circuit die having ferroelectric components to minimize the exposure thereof to hydrogen. The outgassing of hydrogen from traditional gold-plated, side-brazed lids is eliminated either by adhesively adhering such lid to a ceramic mounting base, or by soldering an unplated lid to the ceramic base. Other packaging techniques of the invention include the use of a glass frit seal with a cerdip package, and prebake steps and epoxy curing steps in an oxygen-rich ambient to offset the presence of any hydrogen such that degradation of the ferroelectric components is reduced.

Abstract: A displacement following device comprises a slider (1) mounted on a slideway (2) for movement along a linear displacement path. A beam (4) mounted on the slider (1) is rotatable about an axis of rotation (5) at its midpoint. A pair of stops (6, 7) spaced apart along the displacement path are fixed to the slideway (2) on opposites sides of the beam (4) and project into the path of movement of the beam. A tension spring (8) has one end connected (at 10) to the slider (1) and its other end connected to a point (9) between the axis of rotation (5) and one end of the beam. The spring (8) biases the beam (4) about its axis of rotation (5) into engagement with the stops (6, 7) so as to bias the slider (1) relative to the slideway (2) into a datum position from which the slider is bidirectionally displaceable along the displacement path. A displacement measuring device can be formed by providing sensing means to sense the displacement of the slider away from the datum position and deliver a measurement signal significant of the magnitude of such displacement.
