Abstract: ABSTRACT As original dialogue recorded live at the time of shooting of a motion picture is often of unacceptable quality a technique, known as post-synchron-ising, wherein the dialogue is re-recorded in a studio and mixed with music and sound effects to form the final sound track, has evolved.   A major problem with this technique is in ensuring synchronism between words and mouth movements. In accordance with a preferred embodiment of the present invention a computer system with a large disc storage is arranged to record and automatically post-synchronise new dialogue with an original guide track.  The system adjusts the timing of the new words primarily by altering the duration of the silent gaps between words and, in acceptable situations, by adjusting the duration of the speech elements.  The decisions controlling this "microediting" of the speech are based on a knowledge of the production and perception of speech and will therefore ensure that the edited speech sounds natural.  The processing does not necessarily take place in real time.  It takes place during recording of the new dialogue, and if necessary, during wind-back and playback phases of the operation and thus causes no delays.

Abstract: ABSTRACT         A tunable oscillator develops a signal having a frequency variable over a range of frequencies in response to a control signal.  A frequency determining resonant circuit includes two voltage-variable capacitance diodes in an arrangement for adjusting at least one endpoint of the frequency range. As a result, the relationship between the magnitude of the control signal and the freguency of the oscillator signal can be adjusted while avoiding mechanically adjustable reactive elements.  The disclosed arrangement is suitably employed with resonant circuits other than those in oscillators.

Abstract: FIBER OPTIC AMPLIFIER Abstract of the Disclosure An optical  fiber bidirectional amplifier includes a pair of small diameter optical fibers, arranged in a side-by-side configuration, the first fiber providing a pumping source and the second fiber doped with a material which will  lase  at  the  frequency  of  the  signal  to  be amplified.  The signal to be amplified propagates through the second fiber to stimulate emission of coherent light from the lasing material,  resulting in amplification of the signal.  The refractive indexes of the first and second fibers are  substantially  identical,  but  the  coupling characteristic provided  by  the geometrical  relationship between the pair of fibers yields a wavelength dependent coupling   efficiency.      Specifically,   the   coupling efficiency  at  the  wavelength  of  the pumping source is relatively  high,  while  the  coupling  efficiency  at  the wavelength of the signal  to be amplified  is relatively low.   Thus, the pumping illumination is coupled from the first fiber to the second fiber to stimulate the doping material  in  the  second  fiber,  while  the  signal  to be amplified remains relatively uncoupled, and is amplified by the coherent light emitted by the lasing material.

Abstract: ABSTRACT OF THE DISCLOSURE         A combination of a rail base plate and fastener clips fastening the foot of a rail to the base plate.  The base plate has a pair of spaced parallel rail foot edge engaging surfaces facing each other and a lower surface.  A pair of identical spring steel U-shaped fastener clips each have an upper limb, a lower limb, and a heel joining the limbs.  The upper surface of the lower limb has an upwardly facing concave surface.  A pair of clip lock protuberances stand up from the base plate.  Aperture surfaces define apertures outboard of the protuberances.  The under surface of each protuberance comprises a downwardly projecting con-vex surface wholly above the said base plate lower surface by a distance which exceeds the thickness of the clip lower limb.  The arrangement is such that, upon assembly, each clip is strained with the lower limb extending through an aperture.  The upper limb bears downwardly on a foot of the rail and each lower limb concave surface bears upwardly against a downwardly facing convex surface.  The invention is of wide application.  In particular it is useful with sleepers that are not new and with differing shapes of sleepers.

The essence of the in-vention consists of adding, to freshly extravasated blood of slaughter animals, salts of alkali metals, preferably sodium or potassium chlorides, in amounts necessary for achieving an electrolyte concentration ranging from 0.085-0.43 mole/dm3, which corresponds to a concentration ranging from 0.5-2.5% by mass of sodium chloride; then the system is left alone for a period of time necessary for solidification of the product throughout its volume, and thereafter the product is thermally hardened.  The method according to the invention can also be realised using animal blood stabilized with salts of alkali metals, by adding a diluent in the form of freshly extravasated blood, water or protein-carbohydrate substances.  Aqueous solution and protein-carbohydrate substances may be acidic but with limitation of the final acidity of the system to a pH value of above 5.7.
