Abstract: ABSTRACT: "Method of and device for determining a nuclear magnetiza-tion distribution in a region of a body."     During measurement cycles for generating and sampling FID signals in NMR imaging devices 9 a 180° pulse and subsequently a 90° excitation pulse are added to the pulse sequence. The 180° pulse produces an additional echo signal. During (the maximum of) the echo signal, the 90° pulse is generated. The waiting period occurring before the beginning of a next measurement cycle can thus be substantially reduced without giving rise to a significant signal loss in the echo signals to be generated during said cycle. In addition to a reduction of the measurement time, NMR images with different contrasts (other intensity distribution) can be provided.

Abstract: ABSTRACT OF THE DISCLOSURE     In a method and apparatus for forming a space section in a pair of concealed-slide-fastener stringers, with a pair of tapes gripped with interengaged coupling elements disposed at the upper side of the tapes, a pair of continuous concealed-slide-fastener stringers upwardly from the under side of the tapes by a pair of laterally spaced and vertically movable dies until head portions of a series of the interengaged coupling elements are exposed to the dies and supported thereon.  A punch is then lowered to cut certain interengaged coupling elements on the raised dies.          Finally, an ejector is raised through the dies to clamp the cut coupling elements against the punch and continues moving upwardly together with the punch to pull the cut coupling elements out of sewn stitches. The present invention provides method and apparatus wherein an element free space section can be formed accurately and without deforming or otherwise damaging the associated pair of tapes.

Abstract: ABSTRACT          A STRAIN SENSOR      A strain sensor includes a quartz crystal element 9 having a resonant frequency which is dependent on strain imposed on it.  The crystal element 9 is caused to vibrate at its resonant frequency by pulses of light transmitted along an optical fibre 5 from a remote location indicated generally at 1.  A signal produced by the vibration at the resonant frequency is taken from electrodes 10 and 12 and amplified at 13 and 14 before being used to switch on and off a switch is controlling a light source 16.  The output from the light source 16, consisting of flashes of light of a frequency indicative of the strain, is transmitted along a second optical fibre 19 and is detected by a photocell 20.  The frequency of the output of photocell 20 is measured at 21 to give the desired measurement of strain and to provide feedback to the drive unit 3 which determines the frequency of the flashes of light produced at 2.

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention relates to an audio frequency amplifier which has two different supply sources receiving electrical power from the terminals of the secondary winding of a transformer.  One of these two power sources supplies the amplifier while the other power source stores electric energy  in a capacitor to supply instant power demands by the amplifier for high active signals.  Therefore, the audio frequency amplifier does not need a large size transformer for being supplied with instantaneous high power.  This new concept applied to audio frequency amplifiers is named Dynamic Power on Demand,(D.P.D.).
