Abstract: IMPROVED METAL DETECTOR                       ABSTRACT OF THE DISCLOSURE          Metal detectors having parallel magnetic fields produce signals which vary depending upon the shape and orientation of a metal object passing through the field.  An improved metal detector sensor includes a magnet of special configuration having a multi-directional magnetic field resulting in a detector which is insensitive to orientation of the detected metal.  One embodiment of the magnet is a pattern of cylindrical poles with the opposing pole central to the cylinder, thus creating a multiplicity of radially extending magnet fields.  An alternative embodiment of the invention is an offset pattern of opposite poles which create two groups of fields, each at an angle to the general direction of movement of the material fed into the machine.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of reinforcing a piling structure by means of a precast concrete pile and hydraulic sealing apparatus which comprises the steps of:  driving a hollow, precast concrete pile into the ground by means of a pile driver, the pile being formed with thin and frangible portions disposed in its inner peripheral wall, holding in suspension a hydraulic cylinder fitted with a resilient rubber packing thereunder at a desired level within the hollow body of the pile, filling the hydraulic cylinder with oil to cause radial swelling of the rubber packing to such an extent that the deformed rubber closes the clearance between itself and the inner periphery of the pile body and thus defines therewith a sealed hollow space under the rubber packing, and pumping pressurized mortar through a hose into the sealed hollow space of the pile until the thin and frangible portions of the pile burst open from increasing internal pres-sure thus enabling the internal mortar to move out through the apertures and penetrate the surrounding soil, with the later hardened masses of mortar solidifying the surrounding ground and serving as claws protruding outwardly from within the      : pile body to prevent settlement of the embedded pile.  A plurali-ty of such claws can be formed along the length of the pile by separate injection of mortar into the divided,  sealed hollow sections of the pile body from the lower to the higher section.          A hollow, precast concrete pile particularly suitable for use in the method has a tapered point and a plurality of spaced-apart recesses disposed in its inner peripheral wall and in an upward-ly spiraling configuration along the length of the pile.

Abstract: ABSTRACT OF THE DISCLOSURE   Rotary devices for atomizing liquid coating material are characterized by a housing having a circular front wall, a generally cylindrical side wall and a plurality of circumferentially spaced passages formed therethrough in proximity with the juncture of the front and side walls.  Coating material smoothly introduced into the housing onto the front or side wall is carried in a thin film by centrifugal force toward and into the passages for being projected therefrom and atomized, and an electrostatic field is established between the device and an article to be coated for electrostatic deposi-tion of coating material on the article.  The device is rotated at a relatively high speed, and the passages bring the coating material to the full rotational speed of the device as it is projected therefrom, whereby atomization and the quality of the coating on the article are improved.

Abstract: SELF-ADJUSTING TOGGLE CLAMPS FOR FACTORY FIXTURES AND THE LIKE                       Abstract Toggle clamps, such as used for factory fixtures, typically have clamping arms which in use extend over a workpiece or workpieces; to remove the workpieces and insert new ones, the clamping arms must be opened wide, typically through an angle greater than 90°.  In prior fixtures this is done by utilizing a conventional four-bar linkage; the fixed geometry of such linkages provides no tolerance for clamping workpieces of different thicknesses except by screw-adjustment of a clamping foot.     The present toggle clamp adjusts itself to a wide range of thick-nesses.  One of its members has a hollow containing a sliding locking wedge mechanism pivot-connected to the toggle link member of the mech-anism, before it assumes the angle for toggle action, the wedge mech-anism is held from locking by a cam on this link member.  The sides of the hollow member are slotted; the pivot pin extends through the slot so that, for wide angle opening, the link can pull on the pin.  In this way variable linkage geometry is provided, with the wedge mechanism sliding and the pin establishing its position in the slot as the clamping arm "sizes" the thickness of the workpiece, preliminary to clamping.

Abstract: ABSTRACT OF THE DISCLOSURE Placement  devices  for  positioning  orthodontic attachments, such as, brackets, on the lingual and facial side of teeth are described.  A tooth engagement plate or other member, which engages the facial side of a tooth for lingual  placement  or  the  lingual  side  for  facial placement, is mounted for pivotal movement at least about a  horizontal  transverse  axis.   An  orthodontic  bracket holder  is mounted to a handle  for both horizontal and vertical movement to permit placement of an orthodontic bracket on the opposite side of a tooth to that engaged by the plate.  In operation, for lingual placement, the tooth engagement  plate  is  positioned  in  engagement with  the facial side of the tooth, the bracket is located in its desired position adjacent the lingual side of the tooth by up and down movement of the handle and vertical movement of the bracket holder.  The bracket, to which adhesive is applied, is drawn into engagement with the lingual side of the tooth to grip the tooth between the front plate and the bracket until the adhesive has cured sufficiently to adhere the bracket to the tooth.   The bracket then is released and the device is removed from the mouth.  The same procedure is used for facial placement, except that the plate engages the  lingual  side and the bracket  is drawn into engagement with the facial side.
