Abstract: 1498371 Compiling INTERNATIONAL BUSINESS MACHINES CORP 22 March 1976 [28 April 1975] 11384/76 Heading G4A A hierarchical structure of program text blocks in a high level language is transformed into a sequence of machine instructions as follows. (1) A pre-translation phase loads a rough text consisting of an ordered sequence of operators and empty operand addresses into a first storage area 25, a list of symbol names contained in the text into a second storage area 27, and numerical values respresenting the hierarchical relationships between the text blocks into a third storage area 24. (2) A sort phase orders the symbol names (storage 27) alphanumerically, by block number, and by symbol declaration type (explicit, contextual and implicit) in that priority. (3) A symbol dictionary 29 is generated by separating from the symbol name storage those symbol names which have not been previously presented, and the addresses of the dictionary entries are inserted into the appertaining empty operand addresses in the rough text 25. The entries in the symbol name list 27 include symbol name (SYMB), block number (B), an indication of the declaration type (D-ART), characteristics relating to the symbol occurrence e.g. information in the declaration statement (ATTR), and an address reference (REF) to the rough text storage. Entries in the sorted symbol name list 27 are selected sequentially by an addressing circuit 60, the block number B is used to select a dictionary address register 64, and the symbol names of the entries from storage 27 and dictionary storage 29 are compared, 70, to determine whether the symbol currently extracted from list 27 has occurred previously in the same block or in a higher level block. Depending on the result of this comparison and the type of declaration, either a new entry is made in dictionary storage 29 or a dictionary address is inserted in the rough text storage 25 at the empty operand address specified by the reference address REF in the symbol name list entry.

Apparatus for coating an article 10<SP>1</SP> with powder comprises a treatment chamber 44, means for defining a path through said chamber for the article, a plurality of spray guns 22<SP>1</SP> spaced in said chamber so as to direct a plurality of sprays of said powder towards said path, means for electrostatically charging said powder and establishing an electrostatic field in the region between the spray guns and the article for effecting deposition of the powder on the article, a receptacle for powder in said chamber and means for fluidising powder in said receptacle. In the embodiment of Figs. 1 and 2 powder to be sprayed is fluidised in reservoir 32<SP>1</SP> provided with a metering control valve 33<SP>1</SP> and is carried via conduit 34<SP>1</SP> to the gun 22<SP>1</SP>. The latter is connected to a high voltage D.C. power supply 38<SP>1</SP> having a control switch 39<SP>1</SP>. As shown each gun has its own reservoir and power supply but the guns may be otherwise arranged for individual control. Each spray gun is slidable in a sleeve 56 for adjustment purposes and the guns may be angularly disposed about the pipe and longitudinally spaced along the pipe. In operation the pipe 10<SP>1</SP> is earthed as at 40<SP>1</SP> and is fed through the chamber. Powder carried to each gun becomes electrostatically charged and under the action of electrostatic force tends to wrap around pipe 10<SP>1</SP> and become deposited thereon. The pipe 10<SP>1</SP> may be heated prior to the application of powder or thereafter so that the powder particles fuse or coalesce over the surface of the pipe and the pipe is subsequently cooled or allowed to cool to set the coating. Any undeposited powder is carried by air streams from air tube 58 around the inside periphery of chamber 44 to a receptacle in the base of the chamber formed by floor 62 through which air is blown to fluidise the collected powder. This promotes flow of the particles by gravity along the floor to a collecting chamber 66 connected to a vacuum source for the removal of the powder. The same vacuum source is connected by conduits 72, 74 to cowlings 50 for pulling air into said cowlings through damper openings 52 to provide air curtains at the ends of the chamber to prevent escape of powder particles therefrom. In another embodiment the receptacle at the base of the chamber is used as a reservoir for the supply of powder and a hopper with a gate feed is arranged to feed fresh powder to the reservoir.

Abstract: 1494546 Resin-impregnated cellulosic fibres BUCKEYE CELLULOSE CORP 20 March 1975 11599/75 Heading D2W A process for the production of cellulosic fibres internally impregnated with a wet strength resin comprises forming an aqueous slurry of swellable cellulosic fibres at a first pH at which the fibres are swollen, mixing a wet strength resin into the slurry, reducing the pH of the slurry to a second pH at which the fibres contract and the resin can be cured, dewatering the slurry and substantially separating the fibres from each other, drying the fibres and curing the resin while the fibres are separated. The cellulosic fibres may be derived from wood or cotton. The wet strength resin may be a urea-formaldehyde, melamine - formaldehyde, polyamide - polyamine - epichlorohydrin, polyethyleneimino, or cationic dialdehyde starch resin. Total mixing time may range from 45 min. to 16 hours. Reduction of pH may be effected by addition of dilute H 2 SO 4 , HCl, or an organic acid e.g. acetic acid or salt thereof. Dewatering may be effected on a Fourdrinier wire, preferably to a fibre consistency of 50-55%, the resulting sheet being uncompacted but partially dried. The fibres may be separated by means of a rotating wire brush or by a wet pulp fluffer. The separated fibres are then heated to cure the resin and are dried using conventional conditions. Any fibrous bundles present may be separated by reslurrying the fibres screening and drying. The cellulosic wetstrength resin impregnated fibres are characterised by having a twisted ribbon fibre form, are substantially incapable of forming hydrogen bonds, have a cupriethylenediamine insolubility of at least 80% are refinable, and promote increased bulk wicking rates in fibrous structures. The resin-impregnated fibres may be used in the following applications:-absorption of liquids, filtration of fluids, cushioning, insulation and bulking.
