Abstract: SEISNIC DATA TELEMETERING SYSTEM                        A B S T R A C T           A plurality of data acquisition and transceiver units are connected in series to a central signal processor through a common telemeter link.  The telemeter link includes a data channel, an in-terrogation channel and a control channel.  The signal propagation velocity through the control channel may, for example, be greater than the signal propagation velocity through the interrogation chan-nel.  The central signal processor sends an interrogation signal through the interrogation channel to the data acquisition units.  After a selected delay, a control pulse is transmitted.  The delay between transmissions of the two signals is proportional to the differential travel time of the signals in the two channels.  Accordingly the sig-nal through the control channel will overtake and intercept the signal propagating through the interrogation channel, at a selected data ac-quisition  unit.  When any selected data acquisition unit receives a control signal through the control channel at the same time that it receives an interrogation signal through the interrogation channel, that unit is activated and a desired function is performed.  The con-trol signal is a square wave pulse having a width which is adjustable by integral multiples of the differential travel time.  By adjusting the width and transmission-time delay of the control pulse, any selected subset of one or more consecutive units may be activated.  Each data acquisition unit may have two or more input channels, which are con-nected in turn through common electronics to the data transmission channel by means of a channel selector or multiplexer.  The interro-gation signal may exist in one of two or more states.  In the first state, in combination with a control pulse, the interrogation signal resets the multiplexer.  In the second state, the inter-rogation signal advances the multiplexer to the next input chan-nel in sequence.

Abstract: ABSTRACT      An improved fibre-optic cable termination which substantially reduces light losses and also facilitates cable termination in the field as opposed to the factory.      According to this method the fibres are compressed by pushing the bundle, preferably sheathed in a thin glass ferrule, into a heated tool having a tapered hole. A protective metal coupling may be incorporated by heating a metal sheath with a tapered bore and pushing the glass sheathed bundle into the metal sheath. The metal sheath may then constitute a pin of a pin and socket optical coupling.           In all cases the temperature and pressure are adjusted so that the individual fibres are squeezed into approximately hexagonal form so as to eliminate the interstices to a substantial extend. The temperature and pressure are, however, limited to prevent any substantial fusion and coalescing of fibres and consequent loss of the optical barrier between them.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the production of hollow finished objects from a strip of plastic material by heat moulding at a moulding station.  The strip is heated then fed to the moulding station.  At least one object is heat moulded and the moulded object is cut from the strip at the station. The mould is opened but only a distance sufficient to allow further feeding of the strip upon completion of the heat moulding and cutting steps.  The strip is fed further so that the portion of the strip from which the object was removed is out of the moulding station and a further heated portion of the strip is in the moulding station.  The further feeding step commences as soon as the mould is open.          A portion of the mould containing the moulded object is moved out of the moulding station and a similar portion of the mould is moved into the moulding station simultaneously with the further feeding step.  The heat moulding and cutting steps are repeated to from at least one further object upon completion of the further feeding step.  The first object is removed from the portion of the mould after the expiration of a predetermined stabilization period.          That period begins with the completion of the heat moulding step and ends during the repeating step. The stabilization period is longer than the cycle time, the latter being the time from the beginning of the heat moulding of one object to the beginning of heat moulding the next object.

Abstract: ARRANGEMENT FOR MONITORING LIVE    CALL DISPOSITION SIGNALS            Abstract of the Disclosure The reliable detection of call disposition signals to identify the ultimate dispositions of calls switched over a cross-office connection is achieved by attaching monitoring equipment to the sender that has been seized by an incoming trunk circuit of a telephone switching office.  Sender release which normally occurs after the completion of outpulsing is inhibited to maintain the trunk in the split condition normally assumed during outpulsing.  A tone detector, attached to the called side of the prolonged split, samples the returning call disposition tones or speech signals and allows a call disposition monitor to preliminarily classify them.  The output of the tone detector is also sent to a computer for more detailed and complete analysis.  If the preliminary categorization indicates that the received signal tone may be part of a disposition category group which requires further sampling and which may allow the calling customer to quickly disconnect, cut-through is delayed for an additional interval to ensure that the computer will have sufficient samples of the incoming signal tones that are free of spurious and random speech and noise energy emanating from the calling side of the split.

Abstract: TOTAL HIP JOINT REPLACEMENT          Abstract of the Disclosure In the replacement of the hip joint, full access to the hip joint is obtained by separating the trochanter, a large protruberance on the upper portion of the upper leg bone, or femur, from the remainder of the femur; and the subsequent dislocation of the hip joint.  Following dislocation, a minimum amount of bone is removed from the femoral ball and sufficient bone is removed from the socket to accommodate the minimum thickness surface replacement elements.  A thin hollow inert metal ball or shell member having an outer diameter close to that of the original hip joint is then cemented onto the upper end of the femur, and an ultra high molecular weight polyethylene cup is cemented into the hip bone socket, with acrylic bone cement.  The metal shell is designed for securing to bone surfaces prepared with precision reaming techniques.  To achieve maximum strength with minimum thickness, both the metal and plastic surface elements, although spherical at their mating surfaces, are thicker at their maximum load bearing points toward the top, and are of lesser thickness elsewhere.  The two joint surface elements which are both generally hemispherical, have inner and outer surfaces which are both eccentric and asymmetric, with the thicker portion of the plastic liner being about 45° of the central hemispherical axis, and the thicker portion of the metal shell being its upper portion.  A clearance of 0.1 to 0.3 millimeters is provided between the metal shell and plastic liner, and the plastic liner is provided with a relieved and contoured inner face to permit maximum range of movement of the joint.  The thickness of the plastic socket is selected to accommodate the variable possible amount of bone removed from the hip socket as needed to provide healthy solid bone support for the cup shaped member and adequate plastic liner thickness to provide the required strength.  Following cementing of the metal and plastic joint surfacing elements into place, the joint is relocated in position, and the trochanter is wired back into position on the femur.
