Abstract: ABSTRACT OF THE DISCLOSURE            In "flying forms" having a plurality of trusses --  usually two  --  with a plurality of beams placed across the trusses and a deck placed on the beams, an extension leg for the truss is provided so that the working height of the truss may be nearly twice its flying height.  The extension leg replaces a truss upright, and mounts using the same bolting arrangement therefor.  The leg comprises inner and outer legs, where the outer leg is secured to the top and bottom chords of the truss, and the inner leg is telescopically engaged within the outer leg.  The shape of the inner leg is such as to accommodate the bolts which secure the outer leg to the truss chords.  Holes are formed in the inner and oouter legs with pre-determined  spacings, and pairs of pins are used to lock the inner leg in any desired position with respect to the outer leg at substantially the desired height.  A screw jack assembly is hingedly secured at the bottom of the inner leg, and may be locked in a downward position for pouring or locked in a swung-up position for flying.

Abstract: 45,361 AUTOMATIC MACHINE TOOL INCLUDING A         MONITORING SYSTEM                 ABSTRACT OF THE DISCLOSURE         An automatic punch press and monitoring system.          The monitoring system includes a piezoelectric accelerometer mounted within the stationary die shoe of the punch press, and electronic circuitry including a variable gain ampli-fier, a detector, an integrator, and a comparator.  The monitoring system is manually placed in a "LEARN" mode whereupon the signal produced by the accelerometer during normal operation of the punch press is amplified, detected, and integrated over the time period of one stroke to pro-duce a test function.  The gain of the amplifier is auto-matically adjusted during successive normal strokes of the punch press until the test function is equal to an arbitrary set point, thereby establishing a reference function.  The monitoring system is then automatically placed in an "AUTO      CONTROL" mode whereupon on each succeeding stroke, with the gain of the amplifier fixed, the test function produced is compared with the reference function.  If the test func-tion is above a first high limit level corresponding to a percentage of the reference function and below a second high limit level corresponding to a second percentage of the reference function a check alarm is activated.  If the test function is above the second high limit level or below a low limit level corresponding to a third percentage of the reference function the punch press is shut down.

Abstract: ABSTRACT      An optical fibre waveguide comprising a glass or vitreous silica fibre is coated with a synthetic resin material, preferably to thermosetting resin such as a polyurethane resin, containing in at least part of its thickness a dispersion of a powdered non-metallic inorganic filler such as lampblack, silica flour or titania powder.  The filler material has a modulus of elasticity at least as high as that of the glass or silica fibre, and its presence in the coating composition increases the elastic modulus of the latter, thus improving the load carrying capacity of the coated fibre, to an extent depending on the thickness of the coating.  The coating preferably consists of a plurality of thin layers, which may be of varying composition in respect of the filler materials incorporated and the proportions of filler used.  A repetitive recycling process for forming a plurality of coating layers on the fibre is described.

Abstract: ABSTRACT OF THE DISCLOSURE      A drive system for a laundry apparatus including a torque sensing drive mechanism for determining the presence of washing fluid in the cavity of a rotary positive displacement pump by means of the different resistive torque responses of relatively f??l an empty pump cavities.  A clutch mechanism joins two driving pulleys that are belt-connected to two driven pulleys on the transmission and pump units.  The presence of washing fluid in the pump cavity effects separation of the driving pulleys and actuates only the pump unit.  Absence of washing fluid in the pump cavity causes the driving pulleys to remain coupled and a centrifugal extraction operation is initiated through the transmission and spin clutch.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is provided for recovering metal compounds and metals from ores, concentrates, alloys and other metal containing materials.  The material containing said metals is leached in an aqueous solution of nitric acid at atmospheric pressure and temperatures which may vary from ambient to the atmospheric boil-ing point.  An inorganic salt is admixed or formed in the solution to raise the atmospheric boiling point of said solution.  The solution is heated to evaporate the water and to increase the concentration of the salt.  The atmospheric boiling point of the solution increases with an increase in the salt concentration and causes an evolution of nitric acid or nitrogen containing gas and the sequential precipitation of metal compounds as the boiling point of the solution increases.  The solution is filtered after each sequential precipitation to recover the metal compound or mixture of metal compounds which have precipitated as aforesaid. Thereafter the metal compounds may be separated and treated by conventional means to produce a relatively pure metal or an alloy.

Abstract: Abstract of the Disclosure A sensor comprising a plate of an oxygen ion conductive solid electrolyte such as stabilized zir-conia, two porous electrode layers of a catalytic metal such as platinum formed on both sides of the electrolyte plate, and two porous ceramic coatings formed respectively on the two electrode layers, wherein both sides of the electrolyte plate are exposable to a gas subject to measurement through the electrode layer and the coating formed on each of them, but the total resistance offered by one of the elec-trode layers and the coating thereon to the permeation of the gas therethrough is different from that offered by the other electrode layer and coating, so that the gas contacts one side of the electrolyte plate with a time lag behind the contact of the gas with the other side of the plate.  The sensor is useful for detecting a fluctuation in the air/fuel ratio of an air-fuel mixture fed to an internal combustion engine across the stoichiometric ratio by exposure to the exhaust gas since the fluctuation and the aforementioned time lag causes the sensor to develop an output voltage.

Abstract: ABSTRACT          A method for filtering a liquid which consists of supplying a liquid to a filter bed and causing the same to move upwardly therethrough and, at the same time, continuously removing filter medium particles from the bottom of the bed to a wash device and allowing the removed particles to flow through the wash device downwardly counter-current to the flow of filtered liquid upwardly therethrough.  The apparatus consists of a casing for confining the zone of filter medium particles in the lower portion providing a filter bed and for confining a zone of filtered liquid above the filter bed.  Means are provided, such as an air pump, for continuously removing filter medium particles from the bottom of the filter bed and transporting the same upwardly therethrough to an upper portion of the casing and discharging the same into an open ended pipe of a wash device disposed in the upper portion of the casing.          An outlet in the upper portion of the casing defines the upper surface of the zone of filtered liquid maintained above the filter bed.  The pipe of the wash device has an open bottom end through which the washed filter medium particles are discharged onto the top of the filter bed and into which also the filtered liquid flows and upwardly through the wash pipe discharging at an elevation lower than the discharge of filtered liquid from the casing.  A deflector is provided below the open bottom end of the wash pipe for spreading the washed filter medium particles on the top of the filter bed.  The liquid to be filtered is supplied directly into the filter bed in the lower portion of the casing and at a higher elevation than the elevation from which the filter medium particles are removed continuously and transported to the wash device.
