Abstract: Abstract The products of a molten salt combustion of hazardous wastes are converted into a cooled gas, which can be filtered to remove hazardous particulate material, and a dry flowable mixture of salts, which can be recycled for use in the molten salt combustion, by means of gas/liquid contact between the gaseous products of combustion of the hazardous waste and a solution produced by quenching the spent melt from such molten salt combustion.      The process results in maximizing the proportion of useful materials recovered from the molten salt combustion and minimizing the volume of material which must be discarded.  In a preferred embodiment a spray dryer treatment is used to achieve the desired gas/liquid contact.

Abstract: ABSTRACT OF THE DISCLOSURE                    A MONOPULSE RADAR ANTENNA          The antenna comprises an array of radiating elements 32 arranged in pairs symmetrically about the bore-sight axis 38. Four hybrid rings 40 form the sum and difference of the signals received by a respective inner pair of elements 32.  The outputs of the hybrid rings are summed and applied to a sum output line 46a and a difference output line 46b.           The signals received by the four elements 32 at each end  of the array are summed separately and applied to a fifth hybrid ring 50.   The outputs of the hybrid ring 50 and the output lines 46a, 46b are combined and fed to a sum port 34a and a difference port 34b.   For generating a secondary surveillance control pattern, a directional coupler 66 divides power at a control port 67 in opposite phases between a central control element 64 and the sum port divider 56a of the feed network. The main interrogation is effected by pulsing the sum port 34a; the coupler 66 routes this power mostly to the divider 56a with a small amount to the central element 64.

Abstract: ABSTRACT   The spindle for a disk drive comprises a dish-like hub for centering a removable disk-like recording media and a magnet chuck for clamping the recording media against an axial position reference surface on the hub. To stabily center the recording media on the spindle and to provide a reference surface for controlling the axial positioning of the media, the hub has a central conical post which extends axially of the spindle beyond the plane of a radially displaced annular rim or flange. The post narrows toward its free outer end with a fixed taper, so that the recording media scats thereon and makes interference contact therewith before reaching the plane of the rim. To clamp the disk to the hub and to seat it against the rim, there is a magnetic chuck comprising an annular magnet which is disposed between the post and rim and a strike ring which is engaged with or embedded in an inner circumferential portion of the disk for deflecting the recording media into contact with the rim. For example, if the recording media is configured as a so-called "air sandwich" for what is known as "second surface" optical recording, the strike ring is advantageously embedded in the media while the air sandwich is being assembled.

Abstract: ABSTRACT OF THE DISCLOSURE        A gas laser is provided in which either or both of two "plug-in" modules, one of which comprises the plasma chamber and the other of which comprises the associated high voltage components and circuitry, can be quickly and easily replaced by relatively unskilled personnel without any need for optical realignment.  This feature makes it possible to use sealed plasma chambers even in apply-cations where lasers are operated only intermittently and the sealed plasma chambers have limited operating life.          With the elimination of the gas handling system, it becomes possible to manufacture compact, and in some important cases, portable and light weight lasers with replaceable plasma chambers and high voltage circuits.  The invention is addressed to lasers operating at low to medium power output.  In a preferred embodiment, each high voltage electrode of the plasma chamber includes a connector plate that extends through the envelope and removably engages a support plate of the module containing the high voltage pulse circuitry.  These support plates are precisely posi-tioned with respect to two resonator mirrors mounted per-manently on a base structure, while the connector plates are precisely positioned with respect to the electrodes and windows of the plasma chamber.  The positioning of the connector plates with respect to the electrodes, the windows and the optical axis is identical for each of the interchangeable plasma chambers.  The module containing Abstract cont...   the high voltage circuitry is releasable positioned on the base by two or more locator pins that retain it in a precise predetermined spatial and angular position with respect to the two mirrors.  The position of this module with respect to the mirrors is identical for each of the interchangeable modules.  The plasma chamber module thus "plugs in" to the high voltage module which in turn "plugs in" to the base structure.  Either or both of the modules are readily exchanged with any other similar modules without optical realignment.

Abstract: ABSTRACT    The invention comes in two parts - a re-potting device and a plant educator device. The plant educator device consists of two components, which, when the base section is assembled, may be installed in the plant pot immediately before the plant is installed. The base section is designed to cause it to be-come root-bound by the plant roots as they grow, thereby caus-ing the plant to support the device. The upper section of the plant educator is to be assembled only as the plant grows, and acts to support the plant as well as training the plant to grow into a selected shape, or form. The re-potter device consists of three components, which when assembled, permits the re-potter to grip the plant educator device and support it in mid-air while the plant pot is withdrawn from the bottom without the necessity of handling the plant itself, therey eliminating the danger of damage to the plant as it is being re-potted. Damage normally sustained in staking a plant is eliminated by install-the base section of the plant educator BEFORE the plant is in-stalled.

Abstract: Abstract:          A combination single/twin edgewise orthodontic bracket incorporating twin tie wings to promote twin ligating capability and over-rotation capability, and also incorporating an intermediate section of single bracket width that defines a precision archwire slot for receiving an edgewise archwire of rectangular cross sectional configuration to promote orthodontic treatment with the edgewise orthodontic technique. Relief grooves between the upper and lower tie wings extend outwardly from the ends of the precision archwire slot and are relieved in both width and depth as they traverse each tie wing mesially and distally to provide for efficient over-rotation control, The relief grooves cooperate with the central bracket section to permit the fullest expression of the advantages of interbracket width, The single/twirl tying bracket features may be employed in a wide variety of bracket structures including "T" brackets, which accommodate loops more conveniently while preserving the advantages promoted by spaced ligating tie wings.          Transverse ligature slots formed in the proximal edges or ends of the bracket permit application of efficient force vectors to the edgewise archwire even when the archwire slot is severely angulated to maintain optimum seating of the archwire within its slot.
