Abstract: ABSTRACT     A process is disclosed for forming bonded fibre and fibre products by utilisation of an improved process for neutralising the catalyst employed in forming the A stage phenol-aldehyde resin or condensate.  This condensate is the actual bonding agent which, when incorporated in a diluted form in a binder composition and sprayed onto the fibres and subsequently heated in an oven, cures and ?onds the fibres to one another.  The condensate is a phenol-aldehyde condensate which is the result of reacting a phenol and an aldehyde in the presence of an alkali metal or alkaline earth metal hydroxide as catalyst to form an A stage or resole resin.  The catalyst, once the reaction has been completed, is then neutralised, either before or after dilution, with an acidic lignosulphonate, or a liquor containing such material.  An organic or mimeral acid can be utilised in conjunction with the lignosulphonate, or lignosulphonate liquor, so as to avoid adding excessive amounts  of 1 gnosulphonate.  The invention is also directed to the novel processes for forming the resin  and binder composition disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE     In a process of manufacturing a spray-dried detergent powder having a high proportion of its detergent-active material in the form of a nonionic surfactant, the tendency of this powder to autoxidise can be counteracted by incorporating into the slurry (a) an alkaline material in an amount equivalent to at least 5% by weight of sodium oxide and (b) from 1/2 to 6% by weight of an alkanolamide.          The weights are based on the weight of the spray-dried powder.  An example of a suitable alkaline material is alkaline sodium silicate.

Abstract: METHOD OF PREPARING SOLVENT-BASED       COATING SOLUTIONS                 Abstract of the Disclosure Disclosed is a novel procedure for making solvent-based polyurethane or polyurethane-polyurea compositions which makes it possible to avoid the production of compo-sitions that are undesirably underpolymerized or over polymerized.  Moreover, the invention shortens the over-all time required to produce the composition.  In essence, the invention involves a reversal in the order of steps usually \ used for making compositions of this sort: after a desired quasi-prepolymer of polyisocyanate and polyol is formed, a relatively small amount of secondary amine is added.  The main polymerization with polyols and/or polyamines and the like is then permitted to take place.  Desirably, as a last step, a suitable quantity of monoisocyanate is added to react with any unreacted amine groups and yield a final solution that has no reactive groups and has consequently an excellent pot life.

Abstract: ABSTRACT         A mold for continuously casting molten metal, which mold has a friction-reducing material disposed so that the surfaces of the copper liner and the steel backing plate of the mold bear against this material instead of directly against each other.          Specifically, the friction-reducing material must possess a coefficient of friction significantly less than the coefficient of friction which results when copper bears against steel.          Consequently, the restraint against thermal expansion is minimized, resulting in less distortion of the liner.

Abstract: ABSTRACT OF THE DISCLOSURE         A two mass vibratory material handling apparatus has a first mass that includes a vibration exciter of the rotary eccentric weight type and a second mass that in-cludes an object to be vibrated.  The two masses are inter-connected by resilient elements designed to permit a de-sired vibration amplification from the vibration exciter to the object to be vibrated.  The vibration exciter has a drive with an adjustable drive ratio located between a fixed r.p.m. at full voltage motor drive shaft and a shaft that rotatably supports eccentric weights.  Variable pitch pulleys or a set of pulleys having various pitch diameters are provided so that pitch diameters can be selected there-from for mounting one pulley on each shaft with a drive belt trained about the pulleys and thus, provide a drive ratio enabling the fixed frequency motor to drive the ec-centric weights at a selected operating frequency.  The resilient elements can be designed to amplify vibration along a predetermined line of attack or to flex in that direction while amplifying vibration perpendicularly there-to or to provide a combination of such vibration amplifica-tions to impart an elliptical motion to the second mass.          The apparatus can be manufactured without undue care in maintaining a designed spring rate for the resilient ele-ments or maintaining the designed weight of the two masses since after manufacture and assembly, the apparatus can be fine tuned by weighing the two masses, measuring the ampli-tude of vibration of the mass including the object to be vibrated at a known frequency, selecting an operating fre-quency for obtaining a desired vibration stroke, and adjust-ing the drive ratio to operate at that frequency.     -1a-

Each bit indicator is formed from a ferromagnetic core magnetizable to either of two opposite stable magnetized states that switch from one stable state to the other upon application of an appropriate magnetizing field. A control element disposed through the core serves to provide the magnetizing field for switching the stable state of the core and also serves as a sensing means for detecting each switch between stable states.          In a modified embodiment, bias magnetizing field sources are employed with the bit indicators to provide a variety of bit sensing operations.

Abstract: METHOD OF STARTING A COMBUSTION SYSTEM       UTILIZING A CATALYST     Abstract of the Disclosure A method and system are provided for starting a combus-tion system utilizing a catalyst, and at the same time provide low emissions of unburned hydrocarbons and carbon monoxide.          The method is particularly applicable to starting such combustion systems which are subject to intermittent opera-tion, such as for example, gas turbines used to power auto-motive vehicles in which carbonaceous fuels are combusted to provide the motive fluid, or furnaces which are used inter-mittently.  In the method, heat, such as produced by elec-trical means or by thermal combustion of a carbonaceous fuel, is employed to bring the catalyst to an operating temperature which will permit rapid oxidation of the carbonaceous fuel.          When the catalyst has been heated to reach such operating temperatures, the start-up heating may be terminated and the normal operation of the combustion zone including the catalyst may proceed.
