Title: Improvements in and relating to the preparation of extracts of coffee and/or coffee substitutes
IPC: A23F5/26
Filed: 1948-06-22
Abstract: Roasted and ground coffee or coffee substitute, or a mixture of both, is pre-wetted with an aqueous liquid, prior to putting the coffee in the extractor, to such an extent that the ratio by weight of water to solid matter does not exceed 0.5 to 1 and is preferably between 0.25 to 1 and 0.5 to 1, whereupon an extraction is made with water or other aqueous liquid.  To obtain a fairly uniform size of particles, the grinding mill is adjusted to give the desired maximum size, and particles smaller than the desired size are removed, as by sieving. The extraction may be carried out by a countercurrent process in a series of extractors, as described in Specification 565,620.  When the concentration of the extract has fallen to about 10-25 per cent, some of it is removed for use as the pre-wetting agent and a freshly charged extractor is connected to the last extractor and the first extractor is disconnected.  Water, milk or sugar solutions may be used instead of coffee extract as the pre-wetting agent.  The extraction may be effected in two stages, firstly at a low temperature, say 15 DEG -30 DEG C. to remove heat-sensitive constituents, and secondly at a higher temperature, say 60 DEG -90 DEG C, to remove the more difficultly-extractible constituents.  If the counter-current process is used, extracting liquid at the higher temperature may be fed to the first extractor, the liquid cooling to the lower temperature during its passage through the extractors.  If necessary, the liquid may be refrigerated to the lower temperature. The extracting liquid may be water, milk, sugar solution or aqueous coffee extracts.  The extract may be further concentrated or dried in vacuo, or spray-dried.  To inhibit objectionable changes of flavour, a non-toxic antioxidant may be added either to the extracting liquid or to the final extract.

Title: Improvements in under-feed stokers
IPC: F23K3/12
Filed: 1920-06-21
Abstract: 145,499. Underfeed Stoker Co., (Assignees of Voe, W. E. de). June 9, 1919, [Convention date]. Operating clutches.-In a driving- mechanism which gives intermittent single revolutions to cranks 16 which operate the rams of a mechanical stoker, the cranks are driven from a constantly rotating shaft 17. The driving-gear for each crank 16 comprises a pinion 18 on the shaft 17 engaging a gear-wheel 19 loosely mounted on the crank-shaft. A clutch for intermittingly connecting the wheel 19 to the crank-shaft comprises a hub 23 mounted on the shaft in which hub slides a block 25 which is urged forwardly by a spring 27 to engage a recess 26 in the wheel 19. The block 25 is retracted to disengage the wheel 19 by an arm 30 pivoted at 31 and having a blade which enters a groove 28 in the block, Fig. 9, inclined faces 33, 29 on the blade and block respectively causing the block to slide in the hub 23. The arm 30 is intermittingly moved to inoperative position by a ratchet-wheel 37 having a pin 36 which engages a cam lug 35 on the arm 30, the wheel 37 being rotated by a pawl 42 on an arm 38 which is oscillated at each revolution of the wheel 19 by a striker roller 41. An adjustable shield 45 raises the pawl 42 from engagement with the ratchet-wheel for a portion of its stroke to vary the rate of drive. To ensure that the arm 30 shall not remain in inoperative position for too great a period a number of the teeth 48 on the ratchet-wheel are made higher than the remainder, the pawl 42 remaining in engagement with these teeth for its full stroke despite the shield 45. The clutch hub 23 is connected to the shaft by a renewable breakpin 50 which fractures in case the ram becomes jammed. In operation, the wheel 19 is constantly rotated by the pinion 18 and actuates the ratchet-wheel 37. After a number of revolutions the of wheel 19, determined by the setting of the shield 45, the arm 30 is lowered to inoperative position by the wheel 37, and the clutch block 25 locks the hub 23 to the wheel 19. The shaft 16 makes one revolution, before the completion of which the arm 30 rises into position to disengage the clutch.

Abstract: 985,579. Frequency discriminators; electromechanical filters. E. PFENDE. May 9, 1962 [May 9, 1961], No. 17783/62. Headings H3A and H3U. A frequency discriminator comprises a ferromagnetic disc loosely supported at spaced nodal points 14 and energized to vibrate radially and concentrically by a winding 10 on a ferrite core magnetically biased by a permanent magnet 8. The disc vibrations induce an A.C. output from a coil 18 in a ferrite pot core 19 biased by a magnet 20 and supported on a screening partition 2 between the input and output windings. A further coil 21 wound on the pot core 21 is also energized from the input through a variable capacitor to cause the combined total output from coil 18 to have a sloping amplitude/ frequency, i.e. discriminator characteristic. The coil 10 may be broadly resonant with a capacitor and resistor in series with the input, but the disc is sharply resonant. The vibration mode may have two concentric nodes. The discriminator may be mounted in a partitioned copper casing as shown and thermostatically controlled in temperature. Other mechanical oscillators may be used, e.g. tuning forks or reeds, having torsional shear, transverse or longitudinal modes of vibration. Specification 578,599 is referred to.
