Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to the reshaping of a read signal in such a manner as to compensate for possible distortions, in particular of its cyclic ratio .  During a time interval selected by a control device as as function of synchronising data present on the disc, the synchroni-sing information is integrated by means of an integrator.          The voltage threshold obtained is compared with the data read by means of a comparator circuit.  The result of the comparison gives rise to a signal of rectangular form.  This signal may usefully serve the purpose of adjusting the phase of the read system.  The device may be utilised in particular in a device for rephasing the clock emitting the read pulses.

Abstract: "APPARATUS FOR DETECTING PICK-UP AT A REMOTE TELEPHONE SET"            Abstract of the Disclosure An improved combination of a hardware and digital signal processing filter for detecting pick-up of a telephone call, solely through audio information on the telephone line, is disclosed. The apparatus employs a high gain band pass filter (28) with no automatic gain control, the output of which goes to a window comparator (30).  The output from the window comparator (31) goes to a digital high pass filter (32) and from there to an integrator 37 for providing a digital output signal (40) indicative of the presence or absence on the telephone line of a signal exceeding a predetermined magnitude within the filter pass band.  The digital signal is then processed by an intelligent digital filter having a set of predetermined threshold values of durations for states of the digital output signal, by which determinations of pick-up are made.  The digital filter is adaptive and learns the ddurations high and low states of the digital output signal as they occur, subsequently checking for deviations from previously learned valid values.  The digital filter includes a digital phase lock loop which will lock onto a periodic but asymmetric pattern in the digital output signal and declare pick-up when lock is lost.

Abstract: ENERGY ABSORBING APPARATUS FOR              PIPING SYSTEM AND THE LIKE                Abstract of the Disclosure Apparatus for absorbing the energy associated with the displacements of pipes and other structural elements due to seismic and other dynamic forces.  The apparatus includes a base on which a number of energy absorbing, plate-like members are mounted in cantilever fashion.  The outer, free ends of the members are coupled to an arm which extends outwardly from the members and has an outer end connected to a pipe or other structural element whose displacement is to be controlled.  Each member has convergent side edges on each side, respectively, of a narrowed central part, and the central parts of the adjacent members are substantially aligned with each other and with the outer end of the arm.  Thus, when the pipe or struc-tural element to which the arm is connected is dis-placed, the energy absorbing members bend, and uniform-ly yield, as the outer free end of the members remain in a plane substantially parallel to the plane of the fixed ends of the members.  The members are thereby kept out of compression or tension which could other-wise cause buckling of the members.  The rod extends through curved slots in a pair of parallel walls secured to the base, the ends of the slots defining stops to limit the travel of the rod and thereby the bending of the members under the influence of extreme displacement of the pipe or structural element.

Abstract: PROSTHESIS OF THE HIP             ABSTRACT OF THE DISCLOSURE           The stem of the cephalic femoral component of a hip prosthesis is bounded by two pairs of longitudinally extending surfaces including two relatively wide and two relatively narrow surfaces.

This reduces the likelihood of loosening of the stem in the medullar canal of the femur wherein the stem is implanted without cement, and the bone around the stem is less likely to be subjected to excessive localized stresses.
