Abstract: ABSTRACT OF THE DISCLOSURE An apparatus used in the treatment of spinal fractures and scoliosis.  A threaded rod carries 2 or more sleeves, each sleeve surrounding a portion of the rod and slidable along the entire length of the rod.  Each sleeve engages a hook to inter-connect the rod with the hook.  The hook includes a base for en-gaging the sleeve.  The base has a bore therethrough which receives the sleeve, and a slot is located parallel to and communicating with the bore.  The slot has a width which is greater than the diameter of the rod and less than the outside diameter of the sleeve so that the rod can be placed into the slotted base of  the hook and held in position by the sleeve which is slipped over the rod and into the bore.  A projecting hook portion is integral-ly connected with the base and is used to engage the bone of the spinal column.  A locking system in the form of threaded nuts engages the rod securing the position of the sleeve so that the entire hook assembly may be held in place with respect to the rod.  When hooks are faced toward each other on a rod, compression is achieved by advancing the threaded nuts.  Likewise, distraction is achieved by reversing the hooks so as to be facing away from each other. The bore in the base may be tapered or may have a smaller portion to prevent the sleeve from sliding completely through the bore.  Opposing openings are located on either side of the base for engagement by an instrument, such as a hook holder, to aid in the placement of the hook assembly before inter-connection with the treaded rod.  Preferably, the hook assembly forms a part of a Harrington compression rod or a tensioning means which interconnects a Harrington distraction rod and a Harrington compression rod.

Abstract: ELECTRONIC CONTROLLER OF HYDRAULIC PRESSURE FOR JOURNAL LOADING                           OF BOWL MILL ABSTRACT OF THE DISCLOSURE         An electronic system particularly suited for effecting control over the pressure of the hydraulic fluid through which the journal loading is established on the grinding rolls (20) of a bowl mill (10) of the type that is employed to pulverize coal.  The subject electronic system is operatively connected in circuit relation to the belt feeder means (12), located externally of the bowl mill (10), that supplies to the bowl mill (10) the coal that is to be pulverized therein.  In addition, the subject electronic system is also operatively connected in circuit relation to the hydraulic power unit (22) of the bowl mill (10) that provides hydraulic fluid under pressure to the grinding rolls (20).          Accordingly, the subject electronic system is operative to monitor both the rate at which coal is fed to the bowl mill (10) and the pressure of the hydraulic fluid supplied to the grinding rolls (20) such that as the feed rate of the coal varies the hydraulic pressure being applied to the grinding rolls (20) can be made to vary so that the grinding forces that the grinding rolls (20) exert can be maintained substantially as an optimum regardless of the rate at which the coal is being fed to the bowl mill (10).

Title: Dust disposal cyclones
Inventor: SOLYMOS LASZLO
IPC: B04C5/30
Filed: 1981-04-03
Granted: 1984-08-14
Abstract: ABSTRACT OF THE DISCLOSURE           The efficiency of dust removal by cyclones may, even in case of cyclones of the recycling type, be improved by providing a gap between the clean air outlet of the cyclone and a flank of its dust laden air inlet which con-nects the dust collecting  chamber of the cyclone with the ambient atmosphere.  Due to the dust laden "primary" air introduced through the dust laden air inlet "secondary" air will be sucked in from the ambient atmosphere.  Such secondary airflow will impel the primary airflow towards the periphery of the dust collecting chamber whereby dust particles carried by the primary air will be congregated in the vicinity of the inner wall surface of the cyclone as they enter its dust collecting chamber.  Thereby, the collection efficiency of the cyclone will considerably be increased since dust particles already travelling in the peripheral portion of the airflow are more readily re-moved therefrom by centrifugal forces.  The energy consump-tion increases only slightly.  Further improvement of the collection efficiency can be obtained by providing a pass-age in the clean air outlet opening into the dust collecting chamber since then the air is recycled from the clean air outlet into the dust collecting chamber in the form of a tertiary air with the suction of the secondary airflow.

Abstract: ABSTRACT The invention relates to a new method and apparatus for the simultaneous cleaning of both seat-surfaces of a double-seat valve of which at least one side thereof is in contact with a liquid product which is flowing through the system in which the valve is located.  Prior to this invention, it was not possible to clean the seat-surface of the closure-member which was in contact with the product at the same time as the other closure-member was being cleaned.  The invention will be particularly useful in the food processing industry as the valve ensures that while the pipeline system on the one side of the valve is being cleaned, none of the cleaning agent reaches the pipeline system on the other side of the valve.  The valve is equipped with two closure-members at least one of which is a slide and the other one of which is a slide or in the form of a seat-plate, said closure members being moved by an actuating means, either independently or together.  When the cleaning of the piping system on one side of the valve is taking place, the invention ensures no cleaning agent enters the other side of the valve.  By means of a partial stroke of one valve-stem and a stop determining the position of the other valve-stem, cleaning of the valve can be carried out when the monitor signals the valves are in a closed position.

Abstract: ABSTRACT          A finite region of overpressure can be created in solid underground formations by the periodic injection of a fluid that has finite gel strength that subsequently, after each injection, partially sets - i.e., equivalently becomes a very much stronger gel.  A region of overpressure is a region in which the static, locked in pressure is larger than what was there before.  A region of overpressure can be used to prevent a roof of a tunnel from caving by adding compressive stresses in the roof.  A sequence of regions of overpressure can be used to lift an arch or dome underground, squeeze off water or gas flows, stabilize dams, foundations, large underground rooms, etc.  In general, the stress or pressure distribution in rock can be altered and engineered in a fashion that is more advantageous than what would have been the case without over-stressing.
