Abstract: Abstract A nozzleless, strainerless filter bottom includes a first set of blocks laid end-to-end in spaced parallel rows to define elongated channels.  Transverse grooves in the lower surface of the first set of blocks provide communication between adjacent channels.  A second set of blocks laid end-to-end in spaced rows which are parallel to and overlap the rows of first blocks form covers for the longitudinal channels.      Transverse slots in the lower surface of the second set of blocks form with the upper surface of the first set of blocks passages through which filtrate and backwash fluid may pass without clogging.  A pair of laterally spaced longitudinal flanges depending from the lower surface of the second set of blocks extend into the lower elongated channels and bear against the adjacent sides of the first set of blocks to pre-vent lateral displacement of both sets of blocks.  Longitudinal ribs extending upwardly from the upper surface of the first set of blocks give added strength thereto and prevent clogging of the passages with filter media.

Abstract: SEMI-CONDUCTIVE STEEL CARRIER PARTICLES                 ABSTRACT OF THE DISCLOSURE            Magnetically-responsive electrostatographic carrier particles having semi-conductive properties are prepared by firing steel shot particles in an oxygen deficient atmosphere as to provide the carrier particles with an oxide coating.          More particularly, commercially available steel shot is placed in a furnace wherein the atmosphere has an oxygen content of less than about 18 percent oxygen and the steel shot is fired at a temperature of between about 900°F and about 1600°F for a period of time of between about 10 minutes and up to about 2 hours.  When employed with finely-divided toner particles to develop electrostatic latent images in a magnetic-brush development apparatus, the carriers have been found to provide developed images having lower background densities and higher resolution than prior known carrier materials.

Abstract: ABSTRACT OF THE DISCLOSURE   A microscope-projector system is employed to image and view a transistion of light and dark on an object.  The position of the shadow corresponds to the vertical position of a portion of the object, and an adjustable device is employed for adjusting the position of the microscope-projector with respect to the object.  A video camera may be connected to the microscope, to project the image on a monitor.  Vertical adjustment of the microscope-projector assembly enables measurement of thickness, for example, with respect ot a reference level.  The scan lines of the video camera may also be employed to locate the position of the shadow to indicate the thick-ness of the object, and also to automatically readjust the position of the shadow to reference level.  Electronic circuitry may also play a part to determine from transition in scan lines the horizontal dimensions of an object.

Abstract: ABSTRACT OF THE DISCLOSURE         A current mirror circuit comprised of three tran-sistor devices, each transistor device including an input terminal and first and second output terminals.  Two of the devices have their input terminals connected together and one output terminal of each device is connected to a respective current output terminal.  The other output terminal of each device is adapted to be supplied with an operating voltage. Each of the first and second transistor devices is formed of at least a pair of transistors connected in Darlington-type configuration.  In one embodiment, these Darlington-connected transistors are of complementary types.

Abstract: 17.7.1977 ABSTRACT :      The invention relates to a dis-charge lamp intended for operation with alterna-ting current, wherein the lamp is provided with an internal capacitor.      According to the invention the capacitor is a temperature-dependent capacitor which is either in series with the discharge tube or is included in a branch which is in parallel with that discharge tube.  The result is that at the relatively low lamp temperature at the beginning of the starting procedure of that lamp the capacitance of the capacitor is relatively high and that in the operating condition of the lamp the capacitance of the capacitor is relatively low.  In the case where the capacitor constitutes a ballast of the lamp (series arrangement) this results in an increased starting current of the discharge tube. In the case the capacitor shunts the discharge path a proper operation of the capacitor, which promotes starting, can be coupled to a situation in which the capacitor in the operating condition of the lamp is hardly of any influence any longer.

Abstract: 291,034 ABSTRACT OF THE DISCLOSURE      A cylindrical coil form, for magnetic coupling with, i.e. applying magnetic fields to an irradiated nuclear magnetic reso-nance gas sample, is provided with peripheral and longitudinal grooves.  The peripheral grooves occupy radial planes, while the longitudinal grooves extend along generatrices of a support for coils.  The peripheral grooves are not helical in form, but are perpendicular to the axis of the coil form to give an accurately axially aligned, i.e. longitudinal magnetic field.          A first coil for providing such strong magnetic coupling along the axis of the coil form is wound in the peripheral, i.e. radial grooves, pairs of mutually adjacent turns being interconnected by short longitudinal, i.e. axial sections of wire in one of the longitudinal grooves.  Additional coils are provided for magnetic coupling, i.e. setting up fields, transverse to the axis of the coil through the use of wires extending down one of the longitudinal grooves and back in another longitudinal groove.          The coil form may be of phenolic material, or it may be trans-parent so that the nuclear magnetic resonance cell may be ir-radiated directly through the coil form.
