Abstract: RATCHETING MECHANISM FOR CIRCUIT BREAKER MOTOR OPERATOR                      ABSTRACT A ratchet wheel is advanced by an oscillating driving pawl in conjunction with a holding pawl to charge circuit breaker mechanism closing springs.  A latch operates in response to the initial lifting of the holding pawl as the ratchet wheel is rapidly advanced by the closing springs to detain the holding pawl in an inoperative position while the closing springs discharge. Lifting of the driving pawl by the advancing ratchet wheel leaves the driving pawl in an inoperative position by virtue of a unique slip clutch coupling between it and its driving motor. The latch releases the holding pawl for return to its operative position automatically during the initial oscillation of the driving pawl to start a new charging cycle.

Abstract: ABSTRACT OF THE DISCLOSURE      In order to surcharge the sludge layer of industrial process tailings ponds with sand to effect dewatering of the sludge, which sludge has been treated with hydrolyzed starch flocculant, at least two tailings ponds are employed in the system.  A first pond receives the process effluent and in-cludes a fines-containing sludge layer.  During summer months, sludge is transferred from the first pond to a second pond. During the winter months, the second pond is allowed to freeze over.  Sand is distributed on the ice surface of this pond such that, upon spring thaw, the sand is deposited in a sub-stantially uniform layer over the sludge layer.  The process may be repeated annually or as needed to obtain multiple sand surcharge layers interleaved with layers of treated, highly dewatered sludge in the second pond.

Abstract: Abstract Of The Disclosure An electromagnetic circuit breaker comprising a solenoid coil and an armature actuatable by the coil.  A tube of non-magnetic material within which is a movable magnetizable core, the tube having a pole piece at one end toward which the armature is attracted on predetermined overload conditions, the core being biased toward the end of the tube away from the pole piece.     An inertial mass is carried by the armature and is pivot-ally and eccentrically connected to a link at one end.  The link has another end pivotally mounted to a fixed supports Thus, when the armature is attracted to the pole piece the inertial mass is caused to rotate at an angular velocity greater than the angular velocity of the armatured so that the current in the coil required o overcome the bias on the armature with substantially no time delay, when the gap between the core and the pole piece is at its maximum, is substantially higher than the current required for a similar device but which omits the inertial mass.

Abstract: ELECTROPLATING OF NICKEL-IRON ALLOYS  FOR UNIFORMITY OF NICKEL/IRON RATIO USING A LOW DENSITY PLATING CURRENT     Abstract The composition gradients associated with the electrodeposition of NiFe over complex topography can be substantially eliminated by using low current density deposition in a region of operation where current density is not a controlling parameter for composition of the deposit. The conditions employed include a plating current density of from 2ma/cm2 to 12ma/cm2 onto objects in a plating bath having a ferrous ion concentration of about 0.15 to 0.3 gm/1 and a nickel ion concentration of about 10 to 14 gm/1.  The PH of the system is maintained at about 3, preferably at a temperature of about 20° - 35°C.  The ratio of nickel ion to ferrous ion concentration is from about 45 to 1 to 70 to 1. The electrolyte for electrodeposition of approximately 80:20 nickel-iron alloy can include chloride and sulfate metal salts of nickel and iron together with boric acid, sodium saccharin, a wetting agent and sodium chloride.

Abstract: ABSTRACT OF THE DISCLOSURE           A glue applicating means is constructed with an elongated shoe floatingly mounted alongside of and urged toward a glue applicator roll by a fluid controlled biasing means.  A longitudinally extending depression in the shoe is substantially closed by the glue roll to define a glue cavity to which glue is fed by a positive displacement pump.  The shoe is mounted so that the downstream end of the shoe is movable away from the glue roll automatically as required to permit glue to exit from the cavity at the same rate it is supplied thereto. This provides what is effectively a self-adjusting nozzle or metering slot extending the full length of the shoe and through which glue is forced from the cavity to form a thin layer of uniform thickness on the outside of the glue roll.

Abstract: A B S T R A C T          IMPROVED MEMORY PROTECTION SYSTEM    USING CAPABILITY REGISTERS            The use of protected capability registers to hold the physical base and limit addresses and access rights for a block of memory and the way in which such registers are loaded using System Capability Tables and reserved segment pointer tables is well known in the prior art.  In the present invention the normal capability load instruction has been enhanced in four major ways:-a) allowing additional capability classes to be handled b) instituting a "load on use" facility c) instituting capability propagation control and d) implementing access reduction facilities The capability classes comprises (i) system store, (ii) system resource, (iii) local store and (iv) passive capability.  The "load on use" facility speeds up the load capability instruction and the change process instruction.  The propagation control mechanism introduces an access bit which controls the storing of the capability pointer preventing the passing of the pointer from one process to another whereas the hardware access reduction facility enables a capability to be loaded into a capability register with reduced access right.

Abstract: ABSTRACT            This invention  is concerned with an apparatus for concentrating a proppant fluid slurry.  It has a particular application in connection with oil or gas wells where recovery is improved by causing fractures or cracks in the rock formation in a well to enable the desired product to move more freely.  These fractures are created by the high pressure injection of a slurry of fluid such as gelled water, a proppant such as sand, a delayed action gel breaker, a foaming agent, and a gas such as nitrogen.   Excess water or other liquid is undesirable in the well but is required because of physical limitations in the pumping equipment.  Hence the need for a slurry concentrator between pump and well head.  Previous concentrators have been unsuitable because of the difficulties resulting from blockages such as slugs of greatly dewatered sand.            A number of inventive features are included in accordance with this invention in its preferred aspect.          The concentration is carried out in a casing containing an axial elongated screen.  Stationary angled vanes direct the slurry in a helical path in the space between the casing and the elongated tubular screen to avoid the problems of rotating members.  The concentrating zone thus provided communicates with a mixing zone where baffles provide restricted flow between the edges of the baffles and the interior of the casing to give a mixing action, disperse slugs of slurry, and to avoid back flow of gas.  The baffles are advantageously of resilient material.  The mixing zone then leads to a foaming zone, followed by the outlet.          It is advantageous to have inlet, concentrating zone, mixing zone, foaming zone and outlet for the foamed slurry in axial alignment and without interruptions so as to give a straight through flow.  There are also inventive features contributing to maintenance in that the interior assembly can be removed as one piece upon removal of the inlet end flange and the removal through an assembly flange of a locating member.
