Title: Process of agglomerating coffee
IPC: A23F5/38
Filed: 1967-01-19
Abstract: In a process for producing coffee agglomerates connected by bonds of melted coffee solids, soluble coffee powder is chilled to below 60 DEG F. and contacted with a moistening fluid to wet the surfaces of the particles, the wet particles are agglomerated and fused by heating to a temperature above their surface fusion point, and the agglomerates are cooled to below 80 DEG F.  According to an example, spray dried soluble coffee powder having a particle size distribution of between 100 and 200 microns was ground to produce a particle size distribution of 95% between 2 and 50 microns.  During the grinding the powder was chilled to a temperature of 15 DEG F. by admission of liquid carbon dioxide to the grinding chamber.  The chilled and ground powder, which had a surface moisture content of between 5% and 15% and a total moisture content of between 3% and 6%, was fed through narrow slots in a vibrating distributor box as a series of parallel sheets to be agglomerated and diverted by jets of steam, two for each sheet, into a cylindrical drying chamber; each sheet was contacted with a first jet of steam (nozzle pressure 15 p.s.i.g.) at an angle of about 90 degrees and a second jet (nozzle pressure 8 p.s.i.g.) disposed at an angle of between 95 degrees and 135 degrees with respect to the direction of travel of the powder stream.  In the drying chamber the moist agglomerates, having a total moisture content of about 5%-6%, were dried and fused at temperatures in the range 150 DEG -250 DEG F. by a flow of hot air.  The warm agglomerates were then chilled by cold air (50 DEG F.) to prevent caking and sticking in storage.

Patent GB-376667-A (GB)
Title: Manufacture of 1-amino-2-alkoxynaphthalenes
Filed: 1932-02-03
Abstract: 1-Amino-2-alkoxynaphthalenes are prepared by causing a 1-halogen-2-alkoxynaphthalene to react with ammonia, or a substance yielding ammonia such as urea, ammonium chloride or zinc chloride-ammonia, advantageously in the presence of a substance that facilitates the exchange of halogen such as copper or its compounds or zinc chloride and, if desired, in the presence of a solvent for the 1-halogen-2-alkoxynaphthalene, such as alcohol. When copper is used to facilitate the exchange of halogen, 2-alkoxynaphthalene is also formed which may be isolated, halogenated and further caused to react with ammonia or an agent that yields ammonia.  In examples; (1) 1-Bromo-2-methoxynaphthalene, ammonia and copper are heated together in an autoclave and the contents after cooling and blowing off the excess ammonia, are mixed with ether; the ethereal solution is separated and 1-amino-2-methoxynaphthalene is precipitated by means of hydrochloric acid gas as the hydrochloride which is then dissolved in water, filtered and the free base precipitated by means of ammonia.  (2) 1-Bromo-2-ethoxynaphthalene replaced the corresponding methoxy derivative used in example 1; the 1-amino-2-ethoxynaphthalene may be purified by distillation in a vacuum and copper may be replaced by zinc chloride or sodium sulphite.  (3) The cooled contents of the autoclave in example 1 are filtered and the insoluble matter is extracted with dilute sulphuric acid, 1-amino-2-methoxynaphthalene precipitated from the extract by means of ammonia.  (4) 1-Chloro-2-methoxynaphthalene replaces the 1-bromo-2-methoxynaphthalene used in Example 1.  (5) 1-Bromo-2-methoxynaphthalene is melted with urea, the mass dissolved in dilute hydrochloric acid, the unchanged 1-bromo-2-methoxynaphthalene being filtered off and 1-amino-2-methoxynaphthalene hydrochloride precipitated from solution by means of sodium chloride.  (6) 1-Bromo-2-methoxynaphthalene, ammonia, an alcoholic solution of ammonia and natural copper C are heated in an autoclave, cooled and after flowing off the excess of ammonia the contents are discharged, filtered and the residue washed with water; the residue is then mixed with sulphuric acid and water and then steam distilled, 2-methoxynaphthalene distilling off; the sulphuric acid solution is again filtered, mixed with concentrated hydrochloric acid and 1-amino-2-methoxynaphthalene precipitated by means of common salt.

A method of securing a helical fin on a metal tube comprises forming a helical groove with a ridge on at least one side in the outer surface of the tube, inserting into the groove one edge of a continuous strip and then forcing the ridge inwards against the fin, the outer part of which is supported perpendicularly to the tube by a rolling tool so that the inner edge becomes bent and keyed to the tube. A flat bottomed groove 3 of width equal to the thickness of the fin and ridges 4, 5 are formed in the surface of a tube 1 by a blunt-nosed tool 2. A strip of metal is fed into the groove 3 by a roll 7 which supports it radially and at the same time rolls the ridge 5 across to fill the groove 3 and bend over and anchor the inner edge of the strip to produce a good mechanical and heat conducting joint.

[Class 89 (i)] [Also in Group XXII] Sheet metal nuts, for example of the type with thread engaging tongues, are anchored with play to one member to be connected and the base section of the nut is formed with a countersink so that when the screw is driven home the other member thus connected is countersunk to result in a flush joint without requiring a separate dimpling operation. The nut 10 is of sheet metal bent into U- shape so that the thread engaging tongues 11 in one arm are in axial alignment with a conical opening 12 in the other arm which is anchored with play to the member B by a strip attached in spaced relation by rivets or welding in depressions 3. On screwing up, the head 9 of the screw countersinks the edge of the hole 7 in the part A into the opening 12, thus producing a flat joint. In a modification the separate anchoring strip is dispensed with, projections from the lower arm of the nut engaging with play under the enlarged heads of rivets in the part B. The nuts are particularly useful for securing cover plates to openings in the fuselage of aircraft. In a further modification a U-shaped nut strip 20, Fig. 11, is attached with play to the mounting tripod elements C of the landing wheel brake for the bolting on of the hub fairing member A<1>.

Title: Improvement in automatic fluid regulating devices

Abstract: 507,252. Fluid-pressure servomotorcontrol systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Feb. 5, 1938, No. 3702. Convention date, Feb. 5, 1937. [Class 135] In a fluid regulator applicable to the regulation of any physical value and establishing between a motive fluid regulating pressure #, the variation # at any instant of time of the value to be regulated, and time t, the relationship the two component pressures are obtained by two separate needle-valve and nozzle systems and compounded by another nozzle and needlevalve system. A pointer 33 of an instrument for measuring the physical value is utilised to regulate the pressure from a constant pressure supply 15 to a power device 16 for effecting a suitable control of the physical value, by means of a valve, for example. The pointer 33 carries a needle-valve 2 which co-operates with a nozzle 1 to vary the pressure from supply 15 in a circuit 6, 7, 8 and in a bellows chamber 9, 6 and 7 being capillary restrictions and 8 an adjustable leak-valve. This pressure acting in the bellows 9 is in direct proportion to the variation # and forms the first component of the equation above and also acts on the outside of a bellows 22 which is opposed through a liquid system including a throttle valve 24 by the constant pressure of the supply 15 acting in a bellows 43. The bellows 22 communicates with a further bellows 21 which has a partition 35 separating it from another bellows 20, this partition carrying a needle valve 18 co-operating with a nozzle 19 to regulate the pressure from the supply 15, through a capillary 17, to a bellows chamber 10. This pressure is dependent upon the flow through the needle valve 24 produced by the variation #, which introduces the time factor t, and forms the second component of the . above equation. Two pressures are thus obtained in the bellows 9 and 10 which are compounded by means of an orifice 14 in the wall 38 of a bellows chamber 11, which is connected to a movable wall 37 between the two bellows 9 and 10, co-operating with a fixed needle-valve 13 and controlling the pressure from 15, through a restriction 39, in the bellows 11 and in the power device 16.
