Title: Improvements in the coating of films
IPC: C08J7/052
Filed: 1960-04-27
Abstract: 937,852. Coated regenerated cellulose film. E. I. DU PONT DE NEMOURS & CO. April 27, 1960 [April 28, 1959], No. 14790/60. Class 140. A coated regenerated cellulose film is produced by applying to one or both surfaces of the regenerated cellulose base film a solution in an organic solvent of a subcoating composition comprising a cellulose derivative that retards the absorption of water by the base film, drying the solution of the coating composition and afterwards applying an aqueous dispersion of a vinylidene chloride copolymer to both surfaces thus subcoated or, if only one surface of the film has been subcoated, to that surface alone and coalescing the said copolymer by drying. The film may be pretreated with an anchoring resin, e.g. guanidine - urea - formaldehyde, phenol-, urea- or melamine-formaldehyde resin, prior to subcoating. The thickness of the subcoating may correspond to a weight of at least 0.2 grams of solids/square meter of coated surface. The subcoating composition may contain the cellulose derivative as substantially the only film-forming material, or may contain a thermosetting resin in addition to the cellulose derivative. The subcoating composition may contain not more than 75% of the thermosetting resin and not less than 25% of the cellulose derivative, e.g. 5 to 50% thermosetting resin and 95 to 50% by weight of cellulose derivative. The thermosetting resin may be a monohydric alcohol-modified melamine-, urea-, or phenolformaldehyde resin, acetone-furfural and triacetin resins. The cellulose derivative may be a cellulose esters, e.g. cellulose acetate, formate, propionate, butyrate, acetate-butyrate, acetatepropionate, acetate-nitrate, acetate-glycollate, acetate-stearate or nitrate which may have a nitrogen content of 10.5 to 12.2%; or cellulose ethers, e.g. methyl, ethyl, butyl, hydroxyethyl, carboxymethyl or benzyl cellulose. The subcoating composition may contain an acid catalyst, e.g. maleic acid and p-toluene sulphonic acid. After application of the solution of the subcoating composition the solvent is evaporated at a temperature such that the thermosetting resin is simultaneously further polymerized. The thickness of the top coating after drying corresponds to a weight of 3 to 12 grams of polymer per square metre of coated surface. The vinylidene chloride copolymer may contain 80 to 97% vinylidene chloride and 3 to 20% of at least one other monomer copolymerizable therewith, examples of which are given. The copolymer may also contain 0.1 to 3% of itaconic, methacrylic or acrylic acid.

Title: A book or sachet of soap and a method of producing same
Inventor: HEATON JOHN EVERETT
IPC: C11D17/00
Filed: 1954-05-22
Abstract: A method of producing soap leaves or sheets for incorporation in a book, sachet, packet or like holder consists in depositing a film of melted soap or soap solution on a flexible, glazed non-porous transparent paper backing material, and then rapidly drying the soap film.  The resulting sheets may be cut to the appropriate size and then mounted in a book.  When required for use, one of the leaves is detached and rubbed lightly in water or between wet hands, whereupon the backing material releases the soap film and may itself be rolled into a small ball.  In a preferred method of manufacture, the paper base is drawn off a roll through a bath of melted coconut-oil-base soap, so that both sides of the paper become coated; the paper is then run through squeezing rollers to remove excess soap and thence to a quick-drying machine, after which the paper is cut into small leaves and is mounted in a book.  The use of a coconut-oil soap is said to facilitate the quick-drying process.

Title: Improvements in paper machines
IPC: D21F2/00
Filed: 1965-04-09
Abstract: To reduce the occurrence of air bubbles between a felt and a web supported thereby in a paper-making or web-handling machine the felt passes over a perforated roll shell through which an outward flow of air is generated at a location uncovered by the felt to reduce the air pressure between the felt and roll shell. The air flow may be created by having the openings in the roll shell angled in an outwardly trailing direction with respect to the direction of rotation of the shell and having skinner blades provided adjacent the shell in the uncovered portion thereof or by constructing the roll shell as a transverse flow fan.  The web may be transferred to the felt at the roll shell either from another felt or from a wire screen.  A stabilizing roll may be provided above the web in an open draw between a couch roll and the roll shell.

In a battery charging system for a vehicle of the type wherein the rectified output 4, 5 of a permanent magnet three phase alternator is regulated to maintain a predetermined voltage, one set of rectifier diodes 10, 11, 12 is provided with thyristors 13, 14, 15 each in anti-parallel connection with a respective diode and controlled by a conventional regulator comprising members 21----28, the arrangement being such that the thyristors are turned on or off when the voltage is above or below the predetermined value to respectively by-pass the alternator output or cause it to be applied to the battery 6. All the thyristors receive gate current from the regulator and thus the alternator output is always by-passed by one of the thyristors and diodes, only these members being provided with heat sinks. A transistorcontrolled warning lamp circuit indicates when the generator is not producing current, Fig. 2 (not shown). Application of the invention to a single phase permanent magnet alternator is described, Fig.3 (not shown).

An arrangement for determining the course error resulting from a craft's own magnetic interference fields in a compass controlled gyroscopic course indicator disposed inside the frame of the craft and a detector of which detects the terrestial magnetic field and also the magnetic field of the said craft, is characterized by a coil arrangement through which current flows and which is outside the frame of the craft, and the external field of which is variable in direction and intensity at the site of the said detector, the course error being obtained as the difference between the predetermined horizontal direction of the resultant of terrestial field and coil field and the reading of the gyroscopic course indicator. The variation in the horizontal field component of the terrestial magnetic field which is detected by probes 29, 30 is compensated by regulating the currents through coils 31, 34, 37, 39. An artificial magnetic field of any desired direction is produced by coils 33, 36, 38, 40 at the site of the detector.

Manual control of the table is obtained bv moving the lever 11 against the action of its spring until its pin is disengaged from the notch 15, after which the lever may be moved to stop or reverse the table. When the table is to be withdrawn from working position, the lever is moved into disengaged position, the stop 23 passes the segment without operating the valve, and a stop 24 finally forces the segment over and causes a pin 27 to force the lever into its neutral position. In order to effect this movement at maximum speed, the stop 23 is provided with a bar 28, which acts through a lever 29 and connections to move a plunger 35 to open a by-pass around the throttle valve.
