Title: Method of roasting coffee,cocoa and the like and apparatus for carrying out same
IPC: A23F5/04
Filed: 1961-02-15
Abstract: 975,407. Roasting coffee &c. H. OSSWALD. Feb. 15, 1961 [March 10, 1960], No. 5646/61. Heading A2Q. Coffee beans, cocoa and the like are roasted by introducing a quantity of beans into a first sealed chamber, raising the temperature within the chamber sufficiently to roast the beans and create a pressure head in the chamber, after completion of the roasting opening a valve between the first chamber and a second sealed chamber in which the pressure is lower than in the first, so causing the beans to pass from the first chamber to the second, closing the valve and decreasing the temperature in the second chamber sufficiently to cool the beans, and finally removing the beans from the second chamber. With the apparatus of the drawing a measured amount of coffee beans from a hopper 23 is fed through valves 31, 21 into a roasting drum 1 heated by a burner 12 and is stirred by an assembly 5, 6 driven by a motor 10 through drive means 7, 8, 9. Valves 19, 21, 26 are closed and a compressor 14 creates a vacuum, whereupon the heated beans lose water, expand and shed their husks. The husks are expelled through a pipe 25 by opening valve 26 and resetting the compressor 14 to blow air through the drum. Valve 26 is then closed and the beans roasted in the sealed drum, the compressor 14 in the meantime creating a vacuum in a cooling drum 2 which is surrounded by a water jacket 13 and equipped with a stirring device as in drum 1. When roasting is complete valve 19 is opened and the beans are sucked into the drum 2 whereupon valve 19 is shut again and treatment of a further batch of beans commenced in drum 1. The roasted beans in drum 2, when cool, are discharged through a valve 28. Valve 28 is immediately shut again to allow the creation of a further vacuum for the next batch of beans. All valves and switches may be operated manually or automatically.

Abstract: 1,101,032. Cartons. ALLARD & FILS. 9 Feb., 1965 [11 Feb., 1964], No. 5648/65. Heading B8P. [Also in Division E2] A carton 1 has shoulders 8, 9 attached to its lid 2, lugs on the shoulders being engageable in recesses 10, 11 in double thickness end walls 5. Each shoulder 8, 9 is larger than the corresponding housing 10, 11 and has to be deformed before introduction into the housing where the lugs on the shoulders abut against the edges 14, 15 of the housing.

Title: Improvements in or relating to self-changing gearboxes
IPC: F16H61/02
Filed: 1953-02-28
Abstract: 730,424. Change-speed gearing. SMITH, A. P. Nov. 18, 1953 [Feb. 28, 1953], No. 5680/53. Class 80 (2). A miniature gear box 11 having the same gear ratios as the constant-mesh clutch-operated main gear box 1 has its output shaft 16 geared at 17 to the output shaft 10 of box 1 while its input shaft 18 carries a permanent magnet 19 co-operating with a soft-iron member 21 mounted with limited spring-resisted lost motion on a shaft 20 geared at 23 to the input shaft 4 of box 1. Shaft 16 is moved axially to engage a selected new gear in box 11 and, with a slight lag due to springs 32, to move a contact arm 30 from a contact stud 31 corresponding to the previously-engaged main gear on to a new stud corresponding to the selected new main gear, so that, by the action of magnet 19 on member 21, normally-closed contacts 22, 24 connected to slip rings 27, 28 are first opened to break the circuit through a solenoid 6 whereby the previously-engaged gear clutch 5 in box 1 disengages. The circuit through the solenoid of the newly-selected main gear is not completed until the engine speed has been adjusted to bring the shafts 18, 20 into synchronism, enabling the contacts 22, 24 to close again. As shown, this adjustment is automatic, there being additional contacts 45 one or other of which engages the contact 22, when the latter disengages from the contact 24, so as to energize one or other of two solenoids 47 acting to open or close the throttle 49, which is connected to the accelerator pedal 51 through springs 52. Shaft 16 may be controlled manually, or, as shown, by a centrifugal governor 44 driven by shaft 16. In this case, the pedal 51 may act through a liner 53 to increase the spring loading of the governor when the pedal is depressed. Alternatively, the relative movement between shaft 20 and member 21 may open and close ports in a pneumatic or hydraulic pipe system operating the clutches 5.

Title: Apparatus for bonding together wooden components

Abstract: 1,029,202. Woodworking; binding edges of non-metallic sheet material. E. KLESSMAN. Feb. 13, 1963, No. 5856/63. Headings B5K and B5L. Apparatus for bonding wood strips to the edges of boards comprises a hopper in which wood strips are stacked and pre-heated and from which they may be individually discharged, and a pair of pressure belts which receive the assembly of board and edging strip or strips and press them together. A board is placed on guide rails and drawn by a pair of endless belts past adhesive applicators which smear the side edges with adhesive. It is then drawn past hoppers in which strips are pre-heated by H.F. electric heaters, a strip being ejected from each hopper and aligned with an edge of the board as it passes. The mechanism for ejecting individual strips is operated by a switch actuated by the leading edge of the board. The assembly of board and edging strips is then fed between a pair of spring- tensioned endless belts which press the strips against the board's edges by the action of a series of spring-loaded rollers placed behind the active length of each belt. Pressure is maintained until the adhesive has set. In a modification the first pair of belt pulleys is arranged to swing outwards to enable the board assembly to be entered between the belts manually, the pulleys then closing up again to press against the board, due to actuation by a stop switch operated by the leading edge of the board. The entire apparatus is mounted on guide rails so that one half, about a longitudinal centre-line, may be moved away from the other half to accommodate boards of various widths.

Patent GB-402410-A (GB)
Title: Improvements in the treatment of aluminous materials
IPC: C01F7/743
Filed: 1932-02-29
Abstract: Hot sulphuric acid is circulated through a body of uncalcined freshly mined and/or unweathered coal-measure shales containing alumina and potash, the shales being in the form of small pieces, until the acid is neutralised to the required extent.  The shales used should have a relatively high content of alumina, and be sufficiently resistant to disintegration to allow solutions containing little or no insoluble matter to be produced.  Freshly mined or unweathered shales are employed, as weathering lowers their resistance to disintegration. Extraction may take place in a single vessel or in a series of vessels worked on the counter-current system.  As the digesting solutions approach neutrality, they are maintained at specific gravities of 1.45--1.56 to prevent precipitation of basic salts containing aluminium, iron, and potassium and to assist neutralisation of remaining acid.  By separating the solution obtained whilst it is still somewhat acid and adding the necessary quantity of ammonium or potassium sulphate, alums may be obtained. For the production of aluminium sulphate, a fully neutralised solution is first diluted and cooled to separate its potassium content as alum, and the remaining solution then concentrated and cooled to recover solid aluminium sulphate.
