Title: Spray nozzle and method of using same
Inventor: SIEGENTHALER KARL
IPC: B05B7/06
Filed: 1963-09-19
Abstract: 1,028,004. Spray-producers; coating apparatus. FABRIK FUR FIRESTONE PRODUKTE A.G. Sept.19, 1963.No. 36986/63 Headings B2B and B2F. A spray nozzle, Fig. 1, for producing a composite spray of two different substances comprises two separate channels 5, 12 which communicate with each other, if at all, only at their outlet ends and are adapted for the passage therethrough of a powdered or liquid substance, a pipe 1 for feeding a liquid such as petroleum and/or oil and/or alcohol into the channel 5, a conveyer screw 6 for feeding powdered material such as graphite and/or mica into the channel 12, a helical channel 4 which gives a swirling movement to air passing through a duct 3 and causes a swirling of the liquid in the channel 5, and a helical channel 11 which provides air passing down a tube 10 with a swirling motion and causes the powder in the channel 12 to develop a swirling motion, the outlet ends 13, 14 of the channels 12, 5 being inclined towards each other so that the swirling jets of substances emerging therefrom intersect each other and form the composite spray. Alternatively powdered material may be sprayed through the channel 5 and liquid through the channel 12 or the nozzle may be used to spray two liquids having different properties. The two substances are rotated in opposite directions by their respective air streams. In order to guide the composite spray two air screens are provided by forcing air through holes 15, 16 which are arranged so that the screens swirl in opposite senses. The spraying angle, Fig. 4 (not shown) may be between 0 degrees - 180 degrees andFig. 5 (not shown) depicts guiding air jets for spraying the composite substance downwardly. Figs 6 and 7 (not shown) depict guide jets for spraying round and elongated articles. Fig. 3 shows an unvulcanized tyre 27 about to be sprayed by a nozzle supported by a member 9 which may be raised or lowered by a hydraulic or pneumatic cylinder. Liquid is fed through a head 22; powder from a hopper 23 containing a rotating wire loop 24. Excess air and spray are exhausted through a perforated lower plate 29. If required an air-solvent mixture may be sprayed first and an air-powder mixture, which adheres to the solvent next.

The member 18 has an end extension 19 which closes an exit passage 29 for a tape on the reel when the ring is fastened and which opens the passage when the fastener is released. The ring 15 has air inlet holes 61 into which air is blown to flatten the tape and outlet holes in the extension one outlet hole 63 (not shown) in the extension is inclined towards the passage to facilitate withdrawal of the tape. A headed pin 57 on the extension projects into a key hole slot in the ring 15 to act as a guide during opening of the ring. A projection in a side wall of the lever engages in a depression 109 in the link 82 to retain the fastener secured. The ring may be secured within a pad member in which it is located by extensions 28. A fastener releasing member is connected by a pin and slot connection with the lever 83. The rings 15 and member 18 of the reel holder may be made of flexible plastics material.

Title: Preparation of nylon polymers
IPC: C08G69/30
Filed: 1958-11-21
Abstract: A nylon polymer having a predetermined melting point is made by suspending the precursor nylon salt in a non-solvent liquid for both the nylon salt and the nylon polymer, and polymerising the salt under controlled polymerizing conditions of temperature and pressure such as to maintain a suspension of substantially unagglomerated solid particles of reaction product throughout the polymerization reaction, and thereafter recovering free-flowing particles of the nylon polymer.  The reaction is preferably effected at such a pressure that the liquid in which the nylon salt is suspended boils during a substantial part of the heating period.  Specified non solvents are kerosene and white medicinal oil.  The specification describes the preparation of polyamides from hexamethylene diammonium adipate and metaxylylene diammonium adipate.

Title: Sorting flat articles
Inventor: DOUST JAMES FREDERICK
IPC: B07C3/14
Filed: 1946-12-31
Abstract: 656,873. Photo-electric sorting. POSTMASTER GENERAL. Dec. 31, 1946, No. 38148. [Class 40 (iii)] Postal packets are sorted by placing coded marks of fluorescent material on them representing by their position, number or emitted wave-band the destination of the packet. The emission from this material when illuminated by a suitable lamp is then used to operate a code-reading machine by means of a photo cell to direct each packet to its correct tray. As shown, marks 1 of fluorescent material are combined with spaces 2 to represent the destination of the envelope. The envelope 10 then passes at about 500 feet per minute between two lenses 3a and 3b. The beam of an ultra-violet lamp fed with alternating or intermittent current is focused on to the packet. The consequent emission from the fluorescent marks as they intercept this beam being used to excite a photo-cell 9 which operates the code reading device (not shown). So that the code-reading machine shall operate at the centre of each fluorescent mark the marks are placed in a standard position on each envelope and the envelope then intercepts light passing from a source 5 to a photo cell 6 through a series of slits in a mask 4, these slits being successively covered or uncovered by the packet to " trigger" the code-reading device. The fluorescent marks may be placed on the packets by coin-freed machines which may also frank the packet. Suitable fluorescent materials mentioned are 4 : 41-di-(paraaminobenzoylamino) - stilbene - 2 : 2<SP>1</SP> - disulphonic acid, that known by the Trade name " Primuline," fluorescein and eosin. The Provisional Specification describes the sorting of articles generally by coded marks on them, not necessarily of fluorescent material and mentions applying the code in the form of embossed slips of paper which are then stuck to the article. Slips of paper stuck to the article and projecting over its edge and having perforations or punched holes may be used. In the case of letters and postal packets the marks may replace the normal cancell ation mark and may be inks or dyes of different colours. The use of phosphorescent instead of fluorescent material is also mentioned.

Title: Liquid phase sintering of metallic carbides
IPC: G21C3/62
Filed: 1962-10-12
Abstract: A sintered refractory metal carbide compact having at least 90% theoretical density is formed from a powder mixture of the refractory carbide and an intermetallic compound XY which forms a eutectic with the carbide at a temperature below the sintering temperature of the pure carbide, X being the metal of the carbide and Y a metal with a relatively high vapour pressure at the eutectic temperature, the powder mixture being compacted and finally sintered, preferably under vacuum at the eutectic temperature. The process is particularly applied to the production of sintered uranium carbide nuclear fuels which have a density of 93-99% of theoretical. Uranium carbide powder 0.01 to 40 microns in size is mixed with 2 to 20% by weight of one of the intermetallic compounds UAl2-4, USi1, USi2, U3Si2 or UBe13 and an organic binder such as camphor.  The uranium carbide should contain 4.8-5.3% carbon and the powder mixture after compaction at 10-50 tons/sq. inch is vacuum sintered at 1200-1500 DEG  C.  The other metal, e.g. Al, of the intermetallic compound is volatilized during sintering.  In a further embodiment sintering is effected under argon in which case the intermetallic compound remains in the sintered body.  The other refractory carbides which may be processed are those of thorium, plutonium, zirconium, niobium, molybdenum. For sintering thorium carbide the following intermetallic compounds are used: ThAl2, ThBe13, ThSi, ThSi2, Th3Si2.ALSO:A sintered refractory metal carbide compact having at least 90% theoretical density is formed from a powder mixture of the refractory carbide and an intermetallic compound XY which forms a eutectic with the carbide at a temperature below the sintering temperature of the pure carbide, X being the metal of the carbide and Y a metal with a relatively high vapour pressure at the eutectic temperature, the powder mixture being compacted and finally sintered preferably under vacuum at the eutectic temperature.
