Title: Improvements in or relating to the production of moulding powders
IPC: C08G12/04
Filed: 1943-10-20
Abstract: A moulding composition is obtained by reacting a urea, an aldehyde, and at least 5 per cent (based on the weight of resin produced) of a diamine-dicarboxylic acid salt, in the presence of at least 15 per cent of water based on the weight of the mixture. Some suitable diaminedicarboxylic acid salts are described in Specification 474,999.  Others are listed in the Specification. The term "urea" is defined as meaning urea, thiourea or derivatives thereof which will react with aldehydes. Mono-sesqui- or di-methylol ureas may replace the mixture of urea and formaldehyde.  The preferred aldehyde is formaldehyde.  A list of other suitable aldehydes is given in the Specification. The ratio of formaldehyde to urea is 1.5-1.0 : 1.  The reaction temperature may vary from 0 DEG  to 100 DEG  C., preferably it is between 50 DEG  and 100 DEG  C.  Reaction is usually carried on until gelation is incipient, as shown by the viscosity of the mixture.  Fillers may be added to the reaction mixture or incorporated latex or clear unfilled products may be produced. Acidic or basic catalysts, e.g. ammonium sulphate, formic acid, sodium hydroxide, or trisodium phosphate may be used in the reaction. The products of the mixture can be moulded at 60-200 DEG  C. and 500-20,000 lbs./ sq. in. pressure.  Moulding catalysts, e.g. b -brom-hydrocinnamic acid, ammonium sulphate, ammonium chloride, benzoic acid or dibromstyrene may be added.  Opacifiers, fillers, pigments, lubricants, or other resins such as phenol-formaldehyde, nylon or cellulose acetate may be incorporated either with the resin syrup before drying or with the dry resin powder.  Unfilled articles are clear and water-white.  The products have good shock-resistance. Examples describe: (1) and (7) the reaction of urea, formaldehyde and hexamethylene diammonium adipate under reflux until gelation occurs, and drying and powdering of the gel.  Articles moulded from the gel are clear, water-white and tough; (2) as in (1) a -cellulose being added as a filler to the partially reacted mixture; (3) as in (1) with hexamethylene diammonium sebacate as the salt; (4) as in (1) with decamethylene diammonium adipate as the salt; (5) as in (1) with ethylenediammonium adipate as the salt; (6) as in (1) with ethylene diammonium sebacate as the salt.

Abstract: 608,228. Typewriters &c. NATIONAL MARKING MACHINE CO. July 6, 1945, No. 17330. Convention date, July 7, 1944. [Class 100(iv)] [Also in Group XL(b)] The operation of printing a list on a laundry listing machine of the kind comprising a list-support co-operating with type wheels is utilized to disable an associated laundry-marking machine of the same general type, the marking-machine being 'rendered operative again manually or when a change of type has been effected. As shown, the marking-machine comprises type wheels set by turning index wheels geared thereto by intermediate wheels, the work being placed on a platen 19, shown diagrammatically, moved up to the type wheels by a fluid-operated piston as described in Specification 569,457. The movement of the platen is controlled from the listing-machine by a normally-closed switch 33, which is opened when a lever is raised to press a platen against the type wheels thereof. The marking-machine is put into operation again after the lever is returned to normal position, either by means of a photo-electric device controlled by a beam of light passing across the teeth of the intermediate wheels, or by a hand switch. The platen 19 is connected by a rod 20 to a piston 21 working in a cylinder 22 connected by a pipe 24 either to a fluid-supply pipe 26 or to an exhaust 27 according to the setting of a valve 25 actuated by a solenoid 38 in a circuit including a switch 40 closed by upward movement of the platen, switches 42, 44 operated by hand, and a switch 47. When the switch 33 is opened, a solenoid 59 is de-energized whereby the switch 47 is actuated to open the circuit to the platen and to close a circuit to a signal lamp 51 which warns the operator that the mark is to be changed. The solenoid 59 also opens a holding-switch 56 whereby the solenoid which is normally energized through the switch from the secondary winding 64 of a transformer, is not energized when the switch 33 closes. Light from a source 70 passing through the spaces between aligned teeth of the intermediate gears falls on a photo-electric cell 80 so as to set up a suppressor potential in the grid 78 of an electronic tube 75. When the type wheels are adjusted to change the mark, the light is cut off, current flows, the solenoid 59 is energized and the switches 47, 56 are restored.' In a modified circuit, Fig. 6 (not shown), a push-button switch is used to complete a circuit to energize the solenoid 59.

Title: Process for the manufacture of dibasic alkaline-earth metal phosphates and luminescent powders containing such phosphates
Inventor: SCHREURS WILLY
IPC: C01B25/32
Filed: 1955-06-20
Abstract: <PICT:0787361/III/1> <PICT:0787361/III/2> <PICT:0787361/III/3> Dibasic alkaline-earth metal phosphates are precipitated by reacing a solution of a soluble ammonium phosphate with a solution of an alkaline-earth metal salt, gaseous ammonia being added during the whole precipitation in a quantity sufficient to overcome the tendency of the pH value to depart from a critical range, referred to below, as the dibasic phosphate is precipitated.  The pH range is selected empirically by trial precipitations and investigation of the product on the thermal balance as illustrated in Figs. 1 to 3.  In these Figures the abscissa is temperature in degree centrigrade and the ordinate is the loss in weight on heating.  Fig. 1 shows a dicalcium phosphate precipitated in an over acid medium the sample losing weight at below 200 DEG  C. and the curve made up of three superposed curves. Fig. 2 represents a sample precipitated in the correct pH range, the regularity of the curve being attributable to a single compound.  Fig. 3 illustrates a sample precipitated in an over basic medium where again a loss in weight below 200 DEG  C. occurs, the curve being made up of two superposed curves.  The impurities in Figs. 1 and 3 are probably mono-basic and tri-basic calcium phosphates.  In the case of precipitation with ammonium phosphate and calcium chloride the pH range is maintained between 5 and 5.1 and in the case of preciptating dibarium phosphate from barium chloride solution, the pH is between 7.2 and 7.4.  An example describes the preparation of dicalcium phosphate.  Calcium chloride solution is first prepared by dissolving limestone in hydrochloric acid to obtain a solution having a pH of 1 and the solution is thereafter purified by adding hydrogen peroxide, barium chloride, infusorial earth and a small amount of commercial phosphoric acid.  The solution is brought to pH 9 by introducing gaseous ammonia and the solution is filtered, neutralized to pH 7 by hydrochloric acid and diluted to obtain a pure solution of calcium chloride.  In a separate vessel mommercial phosphoric acid is purified by adding barium chloride, hydrogen peroxide and a small amount of the above pure solution of calcium chloride.  The solution is thereafter brought to a pH of 8 by gaseous ammonia the solution is filtered and acidified to pH 5 by means of hydrochloric acid.  A pure solution of dibasic ammonium phosphate is thereby obtained.  The latter solution is agitated and the pure solution of calcium chloride is introduced slowly at room temperature and during the precipitation the pH is maintained strictly between 5 and 5.1 by continuous addition of gaseous ammonia.  The end of the precipitation is indicated by a tendency of the pH to rise at which point the precipitate is drained off, washed and dried at 200 DEG  C.
