Abstract: ABSTRACT OF THE DISCLOSURE          A pneumatic hammer is provided with a handle which is isolated from the body of the tool so that vibrations of a recip-rocating hammer are dampened.  This is accomplished by a shock ab-sorbing insert located between the handle and reciprocating hammer. The insert includes a rubber cushion member bonded to two steel coupling members, one of which is bolted to the handle and the other which is bolted to the body of the tool.  An air passageway extends through the handle and cushion member to reciprocate the hammer.  To protect the rubber from deterioration from the oil transported with the pressurized air, a neoprene liner is provid-ed which extends through all of the members and which also has a flange at the remote face of each of the coupling members to pro-vide sealing gaskets thereat.   1.

Abstract: Abstract of the Disclosure A high speed sheet-material separating and feeder system is disclosed which handles a wide range of mixed thickness and sizes of envelopes and sheets.  In a free running mode, the system can conservatively handle 30,000 pieces of mail per hour.  The sheets are stacked at one end of the system, and are fed to a first of two separator mechanisms.  The first separator mechanism is adjusted for thicker sheets of the range.  Sheets leaving the first separator are then fed to the second of the two separator mechanisms.  The second separator is adjusted for thinner sheets of the range.  Sheets leaving the second separator are ejected one at a time, in seriatim, where they then can be fed to other sheet handling equipment for processing.         The second separating mechanism is disposed downstream from the first separating mechanism by a length less than that of a minimum size envelope length.  Each of the mechanisms includes a forward envelope thrusting element and an adjacent envelope retarding element for separating multiple envelopes disposed therebetween.  The mechanisms include independent clutching devices for engaging and disengaging each of the forward envelope thrusting elements, respectively, and an overrunning clutch for each of the forward envelope thrusting elements for allowing an envelope to be pulled forward when its respective forward envelope thrusting element is disengaged.

Abstract: ABSTRACT         The invention relates to a device for electrostatically purifying non-conductive liquids such as oil.  Separation of fine particles in the liquid is materially enhanced by position-ing dust or particle collecting members in a direction parallel to the direction of the electrostatic field set up between opposed electrodes.  Anode and cathode plates are disposed in a tank in opposed parallel relationship.  Liquid enters the tank near its bottom and through a conduit having apertures, is discharged or directed upwardly between the opposed plates.  A plurality of dust or particle collecting members made of porous dielectric fiber material are positioned between opposed plates and arranged in parallel with the direction of the electric field when set up between opposed plates and also is in parallel upward flow of liquid.  Liquid is drawn off from the tank at a point above the plates whilst precipitate collecting in the tank bottom may also be conveniently withdrawn.

Abstract: ABSTRACT OF THE DISCLOSURE:           This invention is concerned with a method of manufacturing shaped articles from crystalline acrylonitrile polymers and copolymers.  This method comprising the steps fo:           - shaping a solution of the crystalline acrylonitrile homo-polymer or copolymer in a mixture containing 50 to 99.5% by weight of a solvent and 0.5 to 50% by weight of a non-solvent to the desired final shape;           - cooling the shaped solution to a temperature below the gelation point of the solution until the solution gelates, without changing its composition and shape, to form a shaped thermoreversible gel; and - removing the solvent from the shaped thermorever-sible gel by means of a liquid miscible with the solvent but incapable of dissolving polyacrylonitrile at temperatures lower that the gelation point of the solution.  This method makes it possible to easily work cyrstalline acrylonitrile homo-polymers and copolymers, for example in open molds or on the surface of liquids immiscible with the solutions.

Abstract: ABSTRACT                A method of manufacturing an electrically conductive layer on an internal wall portion of a cathode-ray tube and a cathode-ray tube manufactured according to this method.  By the addition of from 3 to 30%  by weight of sodium carbonate or potassium carbonate to a suspension consisting of a conductive material and a binder, a suspension is obtained which, after having been provided on the said wall portion and dried, provides a layer in which hardly any bubbles have formed during the firing of the cathode-ray tube and which during firing produces no gases which detrimen-tally influence the emission of the cathode.                As a result of this, during assembly and operation of the cathode ray tube no separate particles will be formed by crusing the bubbles, and consequently picture defects and breakdowns in the electrode configuration for generating electron beams will be prevented.  In addition, it has been found that the cathode is less attacked so that a higher emission during the life of the cathode-ray tube is obtained than when other alkali metal salts are used.

Abstract: Abstract of the Disclosure A range of weld metals is disclosed that is resistant to changes in nil-ductility transition temperatures (NDTT) caused by expo-sure to neutron fluences greater than 1 x 1017 neutrons per square centimeter. Designed for use in nuclear reactor pressure vessels, the weldment that exhibits this resistance to neutron-induced ductility decreases is characterized by the condition that an index is less than 0.4.  That index is the ratio of the sum of the weight percentages of nickel and silicon in the metal to the sum of the weight percentages in the metal of manganese, chromium and molybdenum.  This constraint on the index, when applied to a weld metal within the composition ranges given in this specification, gives a weldment resistant to neutron-induced property changes.
