Abstract: Abstract For recording the nuclear magnetic resonance in selected areas of a body for the purpose of representing body cross-sections in the form of images (NMR tomography), wherein the nuclear spins of a selected type present in the area of one plane of the body are subjected to a super-imposed gradient field varying in the selected cross-sectional plane, and selectively excited, the excitation of the nuclear spins is effected by application or a pulse sequence which induces the nuclear spins to supply at one stage a number of chronologically successive induction signals. The induction signals corresponding to each other in chronolical sequence are then processed to obtain separate sets of image signals so that by one single measurement a sequence of cross-sectional images is obtained which differ from each other by  the intensity of the excited nuclear spins which varies according to the relaxation times T1 or T2. The fact that all images have been obtained by one and the same measurement provides the possibility to determine the relaxation times T1 and/or T2 related to the individual image points and to use them on the one hand for purposes of selective image representation and, on the other hand, for improving the image quality.

Abstract: ABSTRACT    An apparatus for manufacturing thermoelectric devices includes two conductive strip receiving fixtures, a thermoelectric element receiving fix-ture and a u-shaped member.  The conductive strip receiving fixtures act to retain the strips in proper registry during the processing steps of screen printing insulating material, or solder paste thereon as well as during attachment of thermoelectric elements thereto.  The element re-ceiving fixture is complemental with either of the strip receiving fixtures to maintain the elements in place during the coupling of the elements to the strips in one of the strip receiving fix-tures.  The strip receiving fixtures are comple-mental with the u-shaped member to complete the coupling of the elements to the strips such that the elements are coupled thermally in parallel and electrically in series.  The u-shaped member also facilitates the introduction of a ceramic potting compound therebetween.    Also disclosed is a method for manufacturing a thermoelectric device.

Abstract: COOLING APPARATUS FOR THE RAPID COOLING OF SPECIMENS       ABSTRACT OF THE DISCLOSURE      A cooling apparatus utilizing liquid nitrogen for cooling specimens to temperatures in the range from -100°C to -195°C in propane, halogenated hydrocarbons, isopentane, or other cooling media.  Freezing of the cooling media is avoided by means of an arrangement wherein the liquid nitrogen cools the cooling-bath container and/or the liquifier only initially, but after the desired cooling-bath temperature has been reached, the liquid nitrogen level is lowered to below the height of a protective shell which results in further cooling being only indirect, via solid/solid contacts and via the gas phase.  A constant cooling-bath temperature is ensured by means of a thermostatic temperature-control system while trouble-free standby operation is ensured by means of an automatic system for replenishing liquid nitrogen, and by a system for controlling the level of liquid nitrogen.  Safe disposal of the cooling media which may be combustible and/or toxic is provided for.

Abstract: Abstract of the Disclosure:         In an optical fiber system comprising first and second polarization-maintaining fibers (41, 42), a first orthogonal coordinate of the first polarization-maintaining fiber is azimuthal-ly rotated relative to a second orthogonal coordinate of the second polarization-maintaining fiber by the use of an optical coupler (40) by a preselected angle between 0° and 90°, both exclusive.          Preferably, the optical coupler is shorter than a beat length of each fiber and the preselected angle is equal to 45°. The optical fiber system is applicable to an optical sensor for sensing a variable physical parameter.  In the sensor, a light beam is incident onto one end of the first polarization-maintaining fiber so that a plane of polarization of the light beam is matched to one of those planes of the first polarization-maintaining fiber which are determined by the first orthogonal coordinate.  A third polarization-maintaining fiber is coupled through an additional optical coupler to the second polarization-maintaining fiber.          The optical fiber system can be manufactured either by twisting and locally fusing a single polarization-maintaining fiber or by splicing two polarization-maintaining fibers.          [Fig. 3]

Abstract: HIGH FREQUENCY SWITCHING       BATTERY CHARGER       ABSTRACT OF THE DISCLOSURE     A power supply for charging a storage battery includes a switching pulse width modulator for controlling the current flowing from an input rec-tifier to an output transformer.  The input rec-tifier is convertable from a full-wave bridge to a voltage doubler for operation at two different line voltages.  A current limiting circuit and a charging voltage control circuit are both respon-sive to sensed output current to closely match the output of the power supply to the charging capa-city of the battery.  An overcurrent sensing cir-cuit protects the power supply and battery against the results of line transients and shorted battery cells.  A sensing circuit detects the absence of a battery, and an end-of-charge sensing circuit detects full charge voltage.  A latching circuit disables the power supply on detection of over-current, absence of a battery, or full charge voltage.

Abstract: Abstract A master/slave clock system including a slave clock configured for inexpensive and relible control from the master.          Each slave clock has an unregulated d-c supply adapted to be supplied with a-c power from the master clock.  Threshold switching means in each slave clock is coupled across the d-c supply to sense an abnormally low d-c voltage level intentionally created by lowering the a-c supply level from the master.  The threshold switching means switches the clock from the normal operating mode to the set mode where time is incremented at a predetermined rate for a duration controlled by the master clock in order to controllably set all slave clocks in the system to the correct time of day.  The system conveniently allows all slaves to be reset to the same time when time is reset at the master, provides for automatic recovery after power failures, and provides a convenient means for automatically resynchronizing all slave clocks twice a day.
