Title: Improvements in devices for delivering measured quantities of granular or like material
IPC: G01F11/40
Filed: 1945-03-09
Abstract: 575,576. Delivering measured quantities of granular material. PRIDDEY, W. T. March 9, 1945, No. 4380/44. [Class 106 (v)] In apparatus for delivering measured quantities of granular material of the kind comprising a tube 6 fitted with alternately operated slides, the latter are actuated by cams 19 mounted on a vertical rotatable spindle 20 which may be driven by hand or by a motor 21. In the form shown, there are provided three slides 5a, 7a, 10a each carrying a roller 23 engaging in the cam groove 22 and the lower part 9 of the tube is, together with the lowermost slide 10a and its operating cam, vertically adjustable to vary the capacity of the measuring chamber. This vertical adjustment is effected by rotating an internally-toothed ring 14 which co-operates with pinions 13 mounted on the upper ends of screwed rods 12, the latter engaging in tapped holes in a flange 15 on the tube 9. If the' measured quantity required is greater than the maximum provided by the telescopic adjustment, the middle slide 7a is cut out and the upper slide 5a, which is normally disconnected, is brought into use. To prevent the granular material from working into the slide covers 5, 7, 10 and so jamming the slides, a semicircular felt sealing pad 26 is inserted in a slot in each slide and at the opposite side two similar pads 25 are mounted in recesses in the cover.

Title: Improving roasted coffee
IPC: A23F5/48
Filed: 1967-01-31
Abstract: 1,145,214. Improving roasted coffee and dried coffee extracts. GENERAL FOODS CORP. 31 Jan., 1967 [10 Aug., 1966], No. 4762/67. Headings A2B and A2Q. In treating whole, subdivided or ground roasted coffee beans, hereinafter referred to as "beans" and "roasted coffee beans", to remove aromas and unwanted gases and thus improve the beans, roasted coffee beans, throughout which 4 to 40% by weight of moisture is equilibrated, are tempered under temperature and pressure conditions and for a time sufficient to allow the moisture. to make contact with the aromas and unwanted gases present, but insufficient to effect further roasting, and' then at least some of the moisture is evaporated. Said range in moisture content may be attained by adding 5 to 35% by weight of water, e.g. water which has been used to quench roasted coffee beans, to freshly roasted coffee beans. Equilibration of moisture content and tempering may be effected at ambient temperature, or by heating roasted coffee beans under super-atmospheric pressure, e.g. in a closed pressure vessel in the presence of water or live, pressurized steam and then opening the vessel to reduce the pressure to atmospheric pressure (see Examples III and IV). Aromas may be recovered from the evaporated moisture, and concentrated, and blended with soluble coffee solids obtained from the treated roasted coffee beans, as by percolating hot water through them to yield an aqueous extract, and then spray-drying this extract.

Patent GB-615307-A (GB)
Title: Improvements in, and relating to, the manufacture of malleable iron
Filed: 1945-02-27
Abstract: In a process for the manufacture of malleable iron from whiteheart iron castings (mainly by decarburization) in a direct-fired furnace, wherein a gas is burnt to supply both the heat and the required malleableizing atmosphere, said gas is burnt in the furnace to partial primary combustion with a supply of air so controlled that the products are substantially non-oxidizing to the castings, and some or all of the products of the primary combustion are burnt in a secondary combustion to pre-heat the primary gas and/or air.  A portion of the heat from the primary combustion may also be used to pre-heat the castings and the gas and/or air used for the secondary combustion, whilst a portion of the heat from the secondary combustion may be also used to pre-heat the castings.  The process is carried out between 950 DEG  and 1100 DEG C, using coal gas, coke oven gas, carburetted water gas, re-formed natural gas or similar gases having hydrogen plus hydrocarbon contents exceeding 48 per cent by volume and calorific values from 380-600 B.Th.W. per c. ft. gross. The ratio of air to gas for the primary combustion being from 2:1 to 2:8:1 by volume; or a gas such as natural petroleum gas of gross calorific value of the order 1000-1150 B.Th.W. per c. ft. may be used in which case the air to gas volume ratio is between 4.7:1 and 6.8:1. Neutral or reducing gases-e.g. burnt and purified towns gas, raw producer gas, industrial nitrogen-may be included in the furnace with the products of the primary combustion, or may be flowed in during the subsequent cooling of the castings in the furnace (down to 680 DEG  C or lower) for complete annealing. The furnace used is gas-tight or substantially gas-tight, the gas and air mixture being injected under pressure so that the whole enclosure is at a pressure slightly above atmospheric, whilst according to the Provisional Specification a "semi-direct" gas-fired furnace may be used.  In a modification, the castings may be heated up electrically and the fuel gases used when the temperature approaches or reaches the malleableizing temperature.

Title: Reading and recording information on record cards and the like
IPC: G06K7/10
Filed: 1956-02-20
Abstract: 818,074. Control arrangements using neuclear radiations. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 20, 1956 [Feb. 22, 1955], No. 5130/56. Class 40 (3). [Also in Group XIX] The invention relates to the recording of information on and reading information from record cards or like storage means and contemplates the use of alpha or beta particle radiators. In one embodiment in which a card 1 reasonably opaque to the radiation concerned is used and the information is recorded in the form of punched holes 2, a scanning station is provided having a radiation source 3 on one side of the card path and a radiation detector such as a Geiger counter 4 on the other. The output of the counter is fed to an amplifier 5 and integrator 6 and the latter feeds the control device 7. This may operate sorting, counting or selecting means. The device 7 may include a distributer operated in synchronism with the movement of the card past the scanning station. In such an embodiment the source 3 may be of radium or mesothorium, radiating alpha particles, or an artificial radio-active isotope with a suitably long half life radiating beta particles. It is an advantage to coat the card with radiation reflecting material and if the card stock alone is sufficiently transparent, information can be recorded by coating certain areas with reflector without the necessity of perforating the other areas. The use of a separate radiation source 3 can be dispensed with if the information is recorded on the cards by depositing a radio-active substance on selected areas thereof. This may conveniently be done by using a solution of a suitable radioactive substance, e.g. radium chloride or strontium nitrate. The detecting and utilization chain may be simplified by the use of gaseous discharge tubes, or crystal counters having a greater output than a Geiger counter thus reducing of eliminating the need for amplification. A gaseous discharge tube having a mica or thin glass window will have its firing potential lowered when exposed to radiation so that it can be arranged to fire and operate a relay when radiation is received.
