Title: Process of treating coffee
Inventor: HALE WILLIAM JOY
IPC: A23F5/02
Filed: 1952-08-15
Abstract: A method of preparing coffee comprises impregnating dried green coffee (which may be decaffeinated) with a solution of non-toxic oxidation promoting porphyrin, e.g. chlorophyllin, solubilized chlorophyll derivative, chlorophyllide, pheophorbin, sodium iron chlorophyllin, potassium magnesium chlorophyllin, solubilized pheophytin, and preferably in an amount not greater than 2 per cent by weight, drying and then or subsequently roasting the coffee up to a temperature not substantially in excess of 400 DEG F for a period sufficient to oxidize a substantial portion of the chlorogenic acid and trigonelline present in the green coffee without substantial oxidation of the caffein if present.  A non-toxic wetting agent, e.g. a non-toxic quaternary amine having germicidal and bactericidal properties in an amount of about 0.1 per cent may be included in the porphyrin.  Examples are given.

Title: A method of and apparatus for the continuous determination of the specific gravity of gases
IPC: G01N9/32
Filed: 1920-07-10
Abstract: 148,575. Ubbelohde, L. July 6, 1914, [Convention date]. Specific-gravity estimating-apparatus.-An apparatus for continuously indicating the specific gravity of gases comprises a pair of meters A, B, connected through nozzles E, E' to a suction device comprising a sealed liquid-containing vessel H into which passes a pipe G open to the air. Reduction of pressure at the surface of the liquid is produced by suction on the pipe F and, owing to the reduced pressure, the gas under test is drawn through the meter A, while a standard gas such as air is drawn through the meter B. The specific-gravity of the gas under test is deduced from the difference between the volumes passing through the meters, which is indicated by a pointer D carried by a differential gear C operated by the meters.

Title: Improvements in telegraphic switchboard systems
IPC: H04L12/04
Filed: 1929-07-04
Abstract: 314,961. Lorenz Akt.-Ges., C. July 5, 1928, [Convention date]. Central station apparatus. - A telegraph exchange switchboard, of the kind in which voltage and no-voltage signals are applied to the subscribers' lines, while positive and negative voltages are applied to the junction lines, is so arranged that similar cords can be employed in all cases. Fig. 1 shows a subscriber's station A working through a switchboard V to a junction line VL, jacks Kl and Kl, being respectively individual to these two lines. If the station A be sending, then at each closure of the key T current flows from negative of battery B (through contact r2 and wire d) through the winding R<1>1 of relay R1, the winding R<11>1 being already energized in parallel therewith from the same source. The windings oppose one another so that the relay R1 is de-energized and the armature r, is moved to the right by mechanical restoring means. Positive of battery B is thus connected (via wire c, lead c1, contact r, and cord a) to the trunk line VL, whereas when contact is broken by key T, contact r1 moves to its left-hand position and negative of battery is connected to line VL, which thus receives signals by reversal of polarity. Outgoing signals to line VL do not affect relay R2: for negative outgoing signals no current flows in coil R<1>2 since both ends of the line are negative, and coil R<11>2 is so polarized that armature r2 remains to the right; while for positive outgoing signals coil R<1>2 takes twice as much current as coil R<11>2, being energized by both batteries in series, and so overpowers it. Incoming positive voltages from line VL energize coils R<1>2, R<11>2 in series and so operate the relay R2. Clearing signals. The clearing signal lamp L, Fig. 2, is lit up when signalling has ceased for a predetermined period. The contacts st1, st2 are closed by the insertion of plugs in the jacks Kl, Kl1. The magnet Z then becomes intermittently energized, through its armature Z.1 which breaks contact when the magnet is energized. The armature Z.2 of magnet Z consequently vibrates, intermittently closing at E.1 the circuit of a ratchet magnet F, which steps a ratchet wheel until the clearing contact F.1 is closed, unless the wheel be previously released by the passage of signals. The latter energizes one or other of the magnets S, S<1>, which are connected in the cord circuits of the exchange. Each signal effects closure of an armature S.1 or S<1>.1, as the case may be, so as to restore the ratchet wheel to its zero position. The number of steps required to close the clearing contact F.1 is such as to ensure that a short pause in signalling shall not clear the line.

Title: Improvements in and relating to rotary filters or separators
IPC: B01D33/00
Filed: 1936-07-27
Abstract: 478,887. Filters. CAMPBELL, R. C. July 27, 1936, No. 20712. [Class 46] In a sectionalized rotary vacuum filter having separate passages for the discharge of filtrate from the several sections, the valve which controls the passages is arranged so that there is a small clearance at the ends of the passages. As shown in Fig. 1, the passages 10 terminate in an annular surface 11 and filtrate is discharged from the interior of the drum through the trunnion 3. A plate valve or shoe 13 co-operates with the surface 11 to close the passages corresponding to the sections from which the cake is being detached. The valve member 13 is supported from a shaft 15 which can be adjusted longitudinally to give the desired clearance between the part 13 and the surface 11 by means of a bracket 21, which screws on the trunnion 2 and engages a thrust bearing 22. Rotation of the shaft 15 is prevented by a counterweight 18 or by an arm 19, the outer end of which can be fixed. The shaft 15 and arm 14 may be made hollow for the supply of air to assist in cleaning the filtering medium. Fig. 3 shows a form of apparatus in which the filtrate is discharged from the sections through separate passages 25 in the end wall of the drum, the hollow trunnion 33 and a fixed right-angle bend 36. The passages 25 corresponding to the sections from which cake is being detached are closed by a frusto-conical valve member 29 carried by a shaft 32 passing through a sleeve 42, which rotates with the trunnion. Longitudinal adjustment of the shaft to give the desired clearance at the valve member is obtained by means of a nut 45 which has an inner flange 46 engaging thrust bearings 47, 48 between rings 49, 50 fixed to the shaft. Rotation of the shaft is prevented by means of an arm 41. A further modification is shown in Fig. 7. The passages 58 from the sections discharge the filtrate into the interior of the drum from which it passes away through the trunnion which is not shown. A valve plate 62 to close the passages corresponding to the sections from which cake is being detached is carried by a pipe 57 passing through the trunnion 54. The pipe also carries a hopper 63 into which wash-water is collected from sections passing under wash-water supply jets for discharge through the pipe 57. The pipe 57 can be moved longitudinally to adjust the clearance of the valve plate by means of a nut 64 with inner flange engaging thrust bearings 67, 68. Rotation of pipe 57 is prevented by an arm 71.

Title: Feeding devices for use in laundries
IPC: D06C15/00
Filed: 1964-05-21
Abstract: 1,025,329. Laundering. H. OELKERS. May 21, 1964 [May 24, 1963; July 27, 1963; Nov. 7, 1963], No. 20973/64. Heading D1A. Apparatus for feeding laundered articles to a treatment machine such as a calender, comprises a carriage movable in any direction, and means mounted thereon for storing laundered articles by winding the latter on a roller or the like. A carriage 12, movable in any direction, has journalled thereon an upper roller 11 and a lower roller 13 interconnected by a band 10 passing over an intermediate roller 14. Rollers 11 and 13 are driven by motors 17 and 18 respectively to wrap band 10 either around roller 11 or around roller 13. The linear speed of band 10 is held constant by motor speed-adjustment means 19, 20 controlled by levers 21 carrying rollers biased against the outer surfaces of the wound rollers 11, 13. Laundered articles W placed successively on band 10 are initially wound on to roller 11. The carriage is then moved to a laundry machine, such as a roller-type ironer, and band 10 is wound on roller 13 to feed the articles in succession to paid machine. The articles, before being wound on roller 11, are freed from creases by rotary brushes 22, 23 which engage the upper surface of band 10. The brushes are carried by in frame 57 which is pivoted at 24 to carriage 12 and is counterbalanced by weight 28. The brushes are interconnected by gearing 27 and are driven by a motor 26. In a modification, Fig. 10 not shown, the movable carriage 10 carrying the rollers 11, 13 is releasably coupled by means of a magnetic clutch 35 to a fixed stand 33 carrying a pair of rotary smoothing brushes 52, 52a. Band 10, in addition to passing over a roller 14, also passes between a pair of rollers 14a, 14c spring-biased towards each other. A motor 36, mounted on stand 33, drives an endless belt 34 conveying the laundered articles under the brushes 52, 52a and on to the belt 10 while the latter is being wound on roller 11. During this operation, roller 11 is driven from motor 36 via gearing 39, a belt 40 and a slipping clutch, roller 14c is frictionally driven by a roller 42 driven from motor 36, while a belt 47 interconnecting rollers 13 and 14c imparts no drive to roller 13 owing to a free-wheel clutch associated therewith. When roller 11 is subsequently unwound to deliver the laundered articles to a rotary ironing machine, roller 13 is driven via belt 47 from roller 14c which is then driven frictionally by a roller associated with the ironing machine. Various alternative methods of smoothing out the laundered articles are described and include endless belts, rollers with right and left handed helical projections, and air nozzles. In an arrangement, Fig. 27 not shown, for handling large articles such as sheets, the latter are initially fed from a hopper 80 to an ascending conveyor belt 75, over a smoothing roller 78, and down a descending conveyer belt 79 to be laid on a horizontal conveyer belt 83. The belt feeds are then reversed, and the articles after passing over smoothing rollers 76, 77 are laid on a conveyer belt 34.
