Abstract: A process for the manufacture of a polycrystalline garnet containing aluminium and/or gallium and/or indium and at least one element taken from the group comprising the rare earths and yttrium, and to the corresponding monocrystal. The process comprises the following steps: (1) a solution containing the salts of the constituent cations of the garnet, in the proportions corresponding to the composition of the latter, is prepared; (2) corresponding hydroxides are co-precipitated by means of a base in order to obtain a co-hydroxide, the solution of salts and the base being added simultaneously at a temperature between ambient temperature and the boiling point of the solution of salts, in such a way that the pH of the medium is between about 5 and 10 and that, within these limits, it is kept at a constant value throughout the co-precipitation; (3) if appropriate, the co-hydroxide is left to age; (4) it is filtered off; (5) it is washed; (6) it is dried; and (7) it is then calcined at a temperature above the temperature for the formation of the desired garnet structure. The monocrystals obtained by Czochralski drawing of the polycrystalline garnets of the invention can be used, in particular, as substrates in magnetic bubble memory devices.

Abstract: ABSTRACT     A conductor support is provided for use with high voltage electrical devices having mounting walls with apertures formed therein  through  which  electrical  conductors  pass.    The conductor  support  is  formed  of  first  and  second  members sequentially inserted in the mounting wall aperture. The first channel member includes walls bendable toward and away from  each  other,  corresponding  to collapsed  and expanded configurations of the first channel member, respectively.            The first channel member is collapsed to take on a reduced cross sectional area, and is inserted through the aperture of the  mounting  wall.  The  first  channel member  includes retaining members, such as notches or grooves, for engaging the mounting wall.  After insertion, the first channel member is expanded to bring the retaining members into  engagement with the mounting wall.   The second channel member is then telescopically  inserted  within  the  first  channel  member, forming an inter-ference fit therewith, while maintaining the engagement between the first channel  member and the mounting wall.  The channel members may be variously embodied, having generally U-shaped, triangular, and circular cross-sectional configurations.

Abstract: ABSTRACT OF THE DISCLOSURE     A drive circuit for an alternate-phase brushless DC motor is arranged to minimize the torque ripple normally occurring with such motors.  The motor has rotor magnets and at least two stator coils, and has a torque relationship in which the rotational torque for each coil extends over an electrical angle of more than 180 degrees and has gradual rising and falling portions intersecting with respective falling and rising portions of the torque of the other coil.  The drive circuit includes a rotary position sensor, such as a Hall element, switching transistors for driving the stator coils, and switching signal forming circuitry responsive to the sensor to switch the switching transistors on and off alternately.  In order to reduce the torque ripple, the drive circuit is made to energize the stator coils in the region of the intersections of the rotational torque, so that the coils are energized for more than 180 electrical degrees.  In one preferred embodiment, a pair of additional switching transistors coupled to the stator coils are switched on by a circuit formed of a pair of differential amplifiers coupled to the Hall element and, through a logic gate, to the additional switching transistors.

Abstract: HIGH-SPEED SMOKELESS COKE OVEN BATTERY          AND METHOD OF OPERATION                 ABSTRACT OF THE DISCLOSURE         A plurality of sole flue-heated, nonrecovery coke ovens constructed in side by-side relation in a battery have their chimney uptake outlets connected to a common combustion tunnel extending longitudinally of and above the battery and connected to stacks at spaced intervals along its length.  Each oven has a bypass  flue directly connecting the top of its coking chamber to the combustion tunnel, and a normally closed valve in each bypass  is operable to selectively connect the coking chamber to the tunnel to permit charging gases to be drawn from the chambers to be burned in the tunnel and stack.  The bypass  valve is closed during coking so that the partially burned gases from the crown of the coking chambers are led through downcomers in the oven walls to the sole flues where a controlled amount of combustion air can be admitted to promote the continued burning process and provide maximum heat in the sole flues.  The gases then pass through the chimney uptakes to the tunnel where additional combustion air can be admitted to assure complete combustion in the tunnel and stack before being discharged to the atmosphere.  Combustion air admitted into the sole flues can be preheated  in pipes extending through the base slab beneath the sole flues where waste heat is extracted to protect the foundation of the ovens while increasing the temperature in the sole flues.

Abstract: ABSTRACT OF THE DISCLOSURE      A warp-knit stringer tape for slide fasteners has a wale-free coarse region extending between a pair of longitudinal warp-knit webs for easy attachment to a knit fabric.  The two webs are interconnected by a connector thread extending trans-versely across the wale-free region.  The innermost wale and the next one or two in each web are disposed closely to one another, thereby providing a widened and thus reinforced wale along the wale-free region.  No heavy or thickened yarns are used for the chain stitches of the innermost opposite wales of the webs, and hence there appear no bulged or increased-thickness wales along the wale-free region.

Abstract: Title of the Invention RETRIEVAL OF LOBSTERS AND OTHER OBJECTS          Abstract of the Disclosure Method and apparatus for retrieving lobsters or similar objects from the floor of a lobster pound or other shallow water body are described.  An upward flow of water is established in a flexible conduit or passageway of size sufficient to accommodate the objects to be lifted.  This is accomplished by a low pressure air lift particularly suited for non-traumatic handling of lobsters.  Objects to be lifted are drawn into the upward flow as the flexible conduit is moved over the bottom.  As objects rise to the surface they are guided or diverted  by a transfer guide chamber or coupling onto a conveyor which carries the objects onto a deck or support platform  floating above the water surface.          The transfer chamber and conveyor shed water away from the lobsters or other objects.  The transfer guide chamber, conveyor and a pivotable boom for supporting the flexible conduit in an "S" configuration are attached to a deck or support platform floating above the surface. The entire rig moves throughout the area of the lobster pound or other water body for recovering lobsters at any location.
