Abstract: TITLE:          IMPROVEMENT IN THE MANUFACTURE OF CYANURIC ACID     ABSTRACT:    Acid digester discharge liquor, from the manufacture of cyanuric acid, containing dissolved triazines, ammonium salts and iron, is treated with a mineral base until the pH is about 2.5 to 4 whereby triazines are precipitated while most of the iron remains dissolved.  The triazines are separ-ated and recycled back to the digester.  The pH of the filtrate is increased to about 11, ammonia is stripped off and recovered leaving an essentially nitrogen free aqueous solution.  This can be discarded or concentrated to recover the salts.

Abstract: ABSTRACT OF THE DISCLOSURE             A method for lining chambers and galleries, especially mining and tunnelling galleries, employs resilient steel supporting frames which consist of a number of box-like section segments capable of being slid one into another and which thus, at least in the zone of overlap, constitute a closed tube.  The ends of the overlapping segments are winded or compressed, as the case may be, and then inserted one into another.  Each overlapping outer section segment is then mechanically compressed in the region of the overlap until ears of the so compressed segment grip behind flanges of the overlapped inner section segment.  A self-locking wedge system providing means of restraint or braking is inserted between each two overlapping outer and inner section segments, and a leading tie and a deformation tie are fitted at the overlap region to the respective ends of the overlapping outer and inner section segments.

Abstract: SEAT BELT SECURING DEVICE            Abstract of the Disclosure:         According to the invention, an occupant restraint system includes a belt having one end anchored outboard the seat and adjacent the lap of the occupant with the other end anchored outboard the seat and adjacent the shoulder of the occupant.  At least one of the belt anchorages is provided by a retractor having a windup spring for winding the belt to a vertically extending stored position.  A belt securing device is mounted on the vehicle body inboard the occupant seating position and includes a housing having pivotally mounted tong arms each having a curved arm portion extending outwardly therefrom for capturing encirclement of the belt.          A spring acts on the tong arms to bias the curved arm portions to an open spaced-apart belt-releasing position.  An actuating member is slidably mounted on the housing and has an actuating bar positioned between the curved arm portions of the tong arms and in the path of entry of the belt therebetween.  Each of the tong arms has an operating leg which extends into engage-ment with the actuating bar of the actuating member so that movement of the actuating bar relative the housing by the occupant or the belt as the belt is entered between the tong arms pivots the tong arms against the spring bias to carry the curved arm portions to a closed position of belt capturing encirclement. A latch member is pivotally mounted on the housing and has a latch spring acting thereon to urge a latch portion into blocking engagement of abutment surfaces on the tong arms to block return of the tong arms from the closed position to the open position.  The latch member also has a button portion by which the seat occupant may pivot the latch member against the bias of the latch spring to move the latch portion from blocking engagement of the abutment surfaces and allow the spring to pivot the tong arms to the open position to release the belt for return to the stored position by the seat belt retractor.  The absence of a securing element carried on the belt allows the use of a retractor having a low-effort windup spring.

Abstract: Abstract The blades of a gas turbine are primarily cooled by the circulation of a coolant through the hollow interiors thereof by the thermosiphon principle. Each hollow blade interior is also placed in fluid communication with secondary coolant source, but secondary coolant flow is precluded by a plug filling the inlet fluid passage. Similar plugs fill apertures in the form of casting holes through each blade airfoil portion, the holes serving to discharge the secondary coolant from the blade interior. The plugs are fabricated of a material having a lower melting point temperature than that of the remainder of the blade airfoil portion such that, in the event of failure in the primary cooling system, the plugs will melt, thereby permitting the secondary coolant to rush through the blade and provide internal cooling thereof.

Abstract: MULTIPLE POSITION HOOK ASSEMBLY            ABSTRACT OF THE DISCLOSURE:      A hook assembly usable with conventional load lifting equipment has a frame and a generally arcuate hook member pivotally assembled to the frame.  The hook member is rotatable relative to the frame between an open position for engagement of a load loop, such as a link or sling, a closed position to secure the load for handling, and a discharge position for dropping the load loop from the hook assembly.  The frame has a contoured portion fashioned to cooperate with a hook member tip and body portion to define a closed, load retaining eye when the hook member is in the closed position, and an open, unobstructed throat when the hook member is in the open posi-tion.  A releasable lock mechanism is assembled with respect to the frame and is operable to hold the hook member in an open position, to lock it in the closed position and to release to allow the hook member to move to the discharge position.  The releasable lock mechanism includes a locking member fixed for guided movement relative to the frame.  An interior end of the hook member has a plurality of projections defining bearing shoulders engageable with the locking member to lock the hook member in the selected open or closed position.  Forces securing the locking member against unlocking are directly proportional to the load on the hook; and the hook member can be remotely released to drop the load loop by setting the load down at a remote location to remove the load from the hook.

Abstract: Abstract of the Disclosure A microprocessor based vital delay circuit is provided which is arranged to emit an output no less than a pre-determined time after an input stimulus.  The predetermined time, which corresponds to the delay, is controlled by selecting the relationship between two quantities.   A digital processor performs a series of computations on the two quantities, each computation is arranged to take uni? time and by selecting the proper relationship between the two quantities, the total series of computations takes a predetermined amount of time.  Before the output is allowed to occur, several checks are performed to insure that no hardware or sofeware failure have erroneously gen-erated the result.  One novel checking technique insures that the clock frequency has not changed, and this tech-nique is applicable to a wide variety of devices in which digital techniques are employed.

Abstract: ABSTRACT OF THE DISCLOSURE          A resistor array formed by the process of forming a plurality of holes or grooves in an electrically insulating substrate, filling the holes or grooves completely with a flow-able, electrical resistance material, and then hardening the resistance material.  The resistance material can be comprised of an electrically non-conductive thermally setting base material throughout which electrically conductive particles are dispersed, or the resistance material can be colloidal or a suspension.  The value of the resistors is determined by the volume resistance of the resistance material and the volume of the holes or grooves, the resistance increasing as the length of the holes or grooves increases and decreas-ing as the cross-sectional area of the holes or grooves increases.  A resistor array having leadless terminals is provided by sandwiching the insulating substrate between layers of electrically conductive material and forming the holes or grooves through at least one of the layers of electrically conductive material and the substrate, and then filling the holes or grooves with the resistance material.
