The receptacle comprises a front open connector body having therein contact terminals and a front cover connected to the connector body through a mount opening formed in a panel.  The contact terminals receives respectively mating contacts of a cooperative plug through the front cover to be connected thereto.  Each of the contact terminals has its rear end portion projecting beyond the rear end of the connector body to define thereat respective terminal lugs by which the connector body is connected electrically and mechanically to a printed circuit board.  Extending rearwardly from the front cover are latch tabs which pass through the mount opening to engage respectively latch ears on the connector body for connection of the front cover with the connector body, in which position a peripheral flange of the front cover abuts against the front edge of the mount opening so as to mount the receptacle on the panel.  Accordingly, the connector body can be attached on the printed circuit board before it is mounted on the panel, permitting the receptacle to be easily mounted on the printed circuit board without being restricted by the panel.

Abstract: ABSTRACT COMPOSITE TAPE LAYING MACHINE AND METHOD   An improved method and apparatus for compacting a composite tape tail which is formed by making a cut along an oblique line across the tape and manipulating first and second compaction means.  The cut, however, severs only the tape while it is adhered to the backing but does not sever the backing or subjacent support (which is usually a strip of paper).  The backing is then peeled away from the strip at a location between the first compaction means shoe, blade, or pad) and a second compaction means (preferably a roller) and conveys the discarded portion of tape to storage, disposal etc.  The first compaction means bears down on the assembly of tape and backing.  The second compaction means engages the tape after the peeling away, hence bears down on only the tail.  Only one compaction means is used at a time.  The second compaction means compactingly engages the tail not later than the arrival of the tail loading edge at said second means by which time the first compacting means has stopped compacting.  Power means, such as an air cylinder, move or switch the two compaction means into and out of respective positions for compaction so that the full width tape is compacted by the first compaction means and the tail (oblique strip without any backing) is compacted by the second compaction means.

Abstract: ABSTRACT OF THE DISCLOSURE     A new orthodontic bracket comprises a bracket body with a mesial-distal slot for the reception of an arch wire and a resilient retainer member for retaining the arch wire in the slot, the retainer member being movable on the bracket body in the occlusal-gingival directions between a slot-closed position and a slot-open position.  When in the slot-closed position the end of the part of the retainer member which closes the slot extends into a mesial-distal extending retainer slot in the gingival wall of the arch wire slot so that movement of the retainer member end in the labial direction is limited by its engagement with the lingual wall of the retainer slot.  The wall that is engaged by the retainer member end preferably in narrower than the bracket body and may comprise a small piece of the spring material used for the retainer member welded to the bracket body.  The engaging faces of the retainer member and the retainer slot may be inclined to retain the retainer member in the slot-closed position.  The small piece may extend gingivally from the body to provide a tie wing that can receive tie wires and elastics when required.

Abstract: ABSTRACT:          In a television transmitter equipment for a television transmission system having a time multiplexed signal in component form, the vision components are derived from a vision source (1), encoded in a MAC encoder (2) and the encoded vision signals are modulated in a frequency modulator (3) which also receives oscilla-tions from an oscillator (4).  The modulated output of the frequency modulator (3) is applied through a multiplexer (5) to a transmitter (6) whose modulated carrier is applied to a dish aerial (7) for transmission to a satellite.  The equipment contains a number of sources (8 to 15) of sound/data information which are separated into two groups, an 'A' group of sources (8 to 11) and a 'B' group of sources (12 to 15).  Digital signals from the 'A' group sources are applied to an 'A' packet multiplexer (17) where the signals are assembled packet-by-packet into a given time area at a bit rate of 10.125 MHz. Correspond-ing signals from the 'B' group sources are applied to a 'B' packet multiplexer (18) where these signals are similarly assembled into a corresponding time area at the same bit rate.  The outputs of the 'A' and 'B' packet multiplexers (17, 18) are applied to respective inputs of a further multiplexer (19) to produce within the time area bits derived from the two packet multiplexers.  This data, the appropriate line sync words from a sync word generator (21) and data from a source (23) for lines 624 and 625 of each frame are assembled in a data assembler (20) to pro-duce the data burst containing the sound/data components  or the time multiplexed signal.  This is modulated in a 2-4 PSK modulator (22) and the modulated output applied to a further input of the multiplexer (5),  The data burst of the signal produced may be readily separated into its two groups to produce a data burst at the lower bit rate from one group for the transmission of a time multiplexed tele-vision signal over a medium of narrow bandwidth such as a cable channel.
