Abstract: Abstract of the Disclosure A tremie tube or a concrete feeding tube for use in feeding fresh concrete under the water consists of an outer tube having desired rigidity and a wall having a number of through-holes, and an inner tube having desired softness.  The lower end of the inner tube is adapted to be closed with a closure means.  This tremie tube is so designed as to be sunk under water, with the lower end of the inner tube being closed with the closure means, so that water  is introduced  through the aforesaid through-holes inwardly of the wall of the outer tube so as to collapse the inner tube under water pressure, with the resulting decrease in buoyancy of the tremie tube.  When the tip of the outer tube reaches the bottom of the water, then fresh hardening-material or concrete is fed into the inner tube under pressure so as to inflate the inner tube, with the result that the closure means is opened  due to the pressure of concrete being fed, thus allowing the concrete to be placed on the bottom of water.

Abstract: ABSTRACT OF THE DISCLOSURE     A control device for a lift truck.  The control device con-sists of a main hydraulic circuit having an adjustable axial-piston pump pivotable in both directions, a hydraulic motor or a plurality of hydraulic motors, a control circuit with a hydraulic pump rotating proportionally with the engine of the vehicle and acting upon the control circuit, and a slide valve controlling the direction of travel.  The hydraulic circuit acts upon the mechanism adjusting the axial-piston pump through control valves containing choke devices.  The control device includes a further hydraulic circuit acting, through an additional hydraulic pump and control valve, upon a lifting cylinder actuating the loading means.  In the case of one known device, the choke adjustment must, of necessity, match the relatively unsatisfactory dynamic travelling stability of the loaded fork-lift truck.  In other words, the deflection velocity is determined by constant choke de-vices from the forward travel for braking to the reverse travel for accelerating.  As a result, rapid acceleration in forward travel, which is advantageous and desirable, and maximum possible retardation in reverse travel, in relation to dynamic travelling stability - at a corresponding pump-deflection velocity - cannot be achieved.  The present invention proposes to overcome these disadvantages by achieving optimal retardation in forward travel and optimal acceleration in reverse travel, without increasing the dimensions of the fork-lift truck, or the weight thereof, in order to ensure adequate dynamic travelling stability.  This is achieved in that arranged between the slide valve controlling the direction of travel and the adjusting mechanism are two double choke-valves.  One of the double choke-valves is for starting and braking in forward travel.  A double choke-valve, used to control starting and braking in reverse travel.

Abstract: ABSTRACT OF THE DISCLOSURE          A lens type optical mode delay equalizer for multimode optical waveguides requires only two parallel lenses as equalizing elements, these lenses each having a cross section corresponding to that which would be formed by cutting away parts of two identical converging lenses by cuts parallel to their optical axes, and joining the remaining portions at the cuts.  The parallel lenses are spaced between the ends of two lengths of waveguide in accos-dance with a relationship involving various parameters of the lenses and the separation and maximum angle of propagation of the wave-guide.  Practical lens configurations may be toroidal or cushion-cuspidal for circular waveguides and bicylindrical or cuspidal for ribbon waveguides.

Abstract: ORGANOPHILIC CLAY HAVING ENHANCED DISPERSIBILITY          Abstract of the Disclosure The invention concerns the discovery that the viscosity of a liquid organic system can be increased by mixing with the system an amount of a specific organophilic clay in the absence of a polar organic dispersant for the organophilic display.  The specific organophilic clay is the reaction product of a methyl benzyl dialkyl ammonium compound and a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of the clay.  The alkyl radicals independently contain from 14 to 20 carbon atoms and the amount of the ammonium compound is from 100 to 120 milliequivalents per 100 grams of the clay, 100% active clay basis.  From 0% to 1.0% of water may also be added to the system.  The invention thus avoids the need for conventional organic dispersants, which have a variety of disadvantages.

Abstract: Abstract The specification describes a method for extracting metals of metal containing substances such as minerals and ores. A mixture of such substances with organic substances is produced. For each equivalent of metal one equivalent is made available in the organic substances of the reducing element and furthermore a sufficient quantity of organic substances is added in order to produce an exothermic re-action. The mixture is pressed to form particles or small bodies, which are introduced, at atmospheric temperature, into a high temperature zone, of at least 800° C, so that an exothermic reaction ensues. This reaction leads to a rise in the temperature at least as far as the fusing point of the metal. The pellets are surrounded with a gas-imper-meable casing before introduction into the high temperature zone and after sharing.

Abstract: ABSTRACT     A lock strike construction is for use with a wall hav-ing at least a cripple in the framing thereof and adjacent to a door casing side rail separated from the cripple by an intervening space.  A door panel cooperates with the casing and has a lock with a bolt engageable with a strike on the door casing in a deeply recessed mortise.  A planar elongated plate, symmetrical about a vertical axis, is in the mortise.  An elongated bolt opening and a pair of screw clearance holes go through the planar plate on the axis.  Also in the planar plate is a pair of screw rod holes, both disposed on one side of the axis.  These receive a pair of screw rods extending through the intervening space and into the cripple as cantilever beams.  The usual strike plate overlies the planar plate, its bolt opening registering with the bolt opening in the plate and its screw openings substantially registering with the screw clearance holes.          Screw fasteners extend through the screw clearance holes in the strike plate and through the similar holes in the planar plate to engage the door casing side rail.

Abstract: STORED ENERGY CIRCUIT BREAKER     ABSTRACT OF THE DISCLOSURE         A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position.  The movable contact is mounted to a contact and spring holder which engages one link in a toggle means.  The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever.  A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate.  The follower plate, which rotates about an axis different from the drive shaft axis, has a drive pawl attached thereto, with the drive pawl being disposed adj-acent the drive pin.  Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions.  The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly.  The outward movement of the cam roller causes rotation of the follower plate, resulting in charging of the spring means.  The degree of rotation of the cam during the charging rotation is more than twice the degree of rotation of the follower plate, thereby gaining a mech-anical advantage.  When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position.  Upon moving into toggle posi-tion, the toggle means moves the contact holder and movable contact into closed position.  Also included are releasable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively.
