Title: Process for the preparation of aromatized, free-flowing soluble coffee
Inventor: CLINTON WILLIAM PATRICK
IPC: A23F5/38
Filed: 1962-06-04
Abstract: 998,419. Coffee agglomerates. GENERAL FOODS CORPORATION. June 4, 1962, No. 21397/62. Headings A2B and A2E. An aromatized, free-flowing soluble coffee is prepared by introducing particles of soluble coffee to a moving contact zone, plating on to the surface of the particles droplets of an aromatizing coffee oil, controlling the ratio of coffee oil droplets to coffee particles so that less than all of the coffee particles are wetted by the coffee oil, continually contacting the wetted particles of coffee with other particles of coffee thereby producing agglomerates of coffee particles, and withdrawing from the zone aromatized mechanically stable non-friable free-flowing soluble coffee containing aromatized agglomerates, the agglomerate phase of the mixture constituting a minor proportion of the volume of the total coffee product. In a preferred procedure, coffee particles 10 (Fig. 1) fed from a hopper 12 are classified on a vibrating screen 18, housed within a chamber 20 filled with carbon dioxide or nitrogen, to provide a median particle size of about 50 mesh (United States Standard) and a particle size distribution of about 5-25% on 40 mesh, 50-85% on 80 mesh and 5-30% through 80 mesh; these particles in moving down a vibrating surface 30 in a contacting chamber 28 as a bed about one inch deep are sprayed with coarse oil droplets having particle sizes in the range 0.003-0.10 inch and in a ratio of 0.01-3.0% by weight of the coffee to give a final product containing less than 10% by weight of agglomerated particles. The coffee oil, which is preferably an expressed oil containing an aroma concentrate, is heated to a temperature above its congeal range e.g. to 60-70‹F., just prior to the spraying; the atomizing gas at the spray 42 may be carbon dioxide. It is stated that spraying may also be carried out on vertically moving beds. The product is stored prior to packaging in an air-tight hopper 50, Fig. 3, in an inert gas environment - carbon dioxide or nitrogen from a pressure source 51 - containing less than about 0.5% by volume of oxygen. Packaging of the coffee product into a container 58 is effected by maintaining a slight positive pressure of inert gas e.g. up to about 0.5 inch of water, above the surface of the coffee product 49 and transmitting pressure and vacuum sequentially through line 64 and line 66, respectively, 3-4 times over periods of 4-5 seconds from the pressure source 51 and vacuum 75. The pressure differential produced may amount to 5-20 inches of mercury. The sequence of operations is accomplished by valves (not shown) actuated by spring blocks 65 in timed relation determined by cams 70 to 73, rotating on a spindle 67. The method of filling the container is claimed in Specification 998,420.

IPC: D06M13/02
Filed: 1956-07-11
Abstract: 802,187. Waterproofing. VAPOR AKTIEBOLAGET. July 11, 1956 [July 14, 1955], No. 21437/56. Class 140. Inherently water-absorbing organic material containing hydroxyl groups is made waterresistant or water-repellent by treating the material with a substance which has an affinity for the organic-bound hydroxyl groups of the material and which is adapted to operate as a catalyst to the polymerization of an organic substance which is thereafter applied to the material. The material treated may be cellulose or synthetic organic material having free hydroxyl groups and may be in the form of foils, fibres, boards and fabrics. The catalyst may be a Lewis acid such as boron trifluoride and polymerizable organic compounds include olefines such as isobutylene, diolefines, acrylic acid derivatives and vinyl compounds. The treatment may be carried out in the liquid or gaseous state, the material being freed from water first. After treatment with boron trifluoride the material is treated with an alkaline substance such as ammonium hydrate or a tertiary amine to neutralize any acid formed by hydrolysis of the catalyst.

Abstract: 1,067,671. Moulding blocks, slabs, pillars, pipes &c. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 2, 1964 [Oct. 4, 1962], No. 21497/62. Heading B5A. [Also in Division E1] Concrete articles are made by introducing a mixture of powdered and/or granular materials and cement an a dry state into a mould having perforations, causing water to pass through the mould perforations by capillary attraction within the material itself and in sufficient quantity only to put the mixture into a state of capillary cohesion without excess of water and allowing the mixture to set. In the embodiment shown dry concrete mixture 5 is permeated with water by inverting a plastic mould 1, on to which a lid 4 has been pressed, into a trough 6 of water. The block may be left in the mould to set or it may be removed once the material is permeated with water, in which condition it can be handled. In further embodiments, pillars, tubes, channel linings and road surfaces are produced by introducing dry mixture ;into .moulds of the appropriate configuration provided with troughs which contain sufficient water to permeate the mixture. Examples are given of moulds of thin flexible sheet material, e.g. polyethylene, in the form of tubes which when filled with dry mixture and sealed at their ends are placed in a bath of water which permeates them. The tube is perforated before or after the introduction of dry concrete mixture The cross-section of the mixture when set may be varied by placing the tube in a supporting mould or by pressing it between parallel plates (25, 26), Fig. 15 (not shown. By means of an adhesive a covering can be affixed to the flexible moulds while the mixture is setting. The moulded articles produced in flexible moulds may be reinforced or secured together by fixing strips having spikes which penetrate into the moulding before the mixture has set, Fig. 19 (not shown). The construction of a catenary roof, Fig. 28 (not shown), is described in which a series of flexible filled moulds (50), Fig. 29 (not shown), having reinforcing wires (53) are secured together with pins (54) and sealed together with sealant (55). The moulds are initially unperforated and to set the mixture they are perforated, e.g. with a spiked roller, and water sprayed over them. Blocks, slabs or the interior of pipes may be provided with a smooth resin surface by bonding thereto a thermosetting resin. In one embodiment, Fig. 30 (not shown), dry mixture (59) is poured into a mould (56) having a flexible plate (57) coated with liquid resin on its base. The resin soaks partially into the bottom portion of the dry mixture and when the resin has set the mould is permeated with water as previously described to produce a rigid article.

Title: Improvements relating to the feeding of wrapping materials to wrapping machines and the like
IPC: B65B41/18
Filed: 1951-09-13
Abstract: 704,697. Feeding webs. FORGROVE MACHINERY CO., Ltd., HARRIS, R. A., PARKER, M., and CARTER, A. F. Aug. 8, 1952 [Sept. 13, 1951],No. 21537/51. Class 100 (1). [Also in Group XL(b)] In machines in which a web of printed material used for wrapping or bag forming is fed to a stage at which its arrival should be accurately registered, e.g. with an article to be wrapped; a detector, e.g. a photo-electric cell, responds to marks on the material to operate an electromagnetic clamp to arrest the feed of the web. As shown, Fig. 1, a web 10 of outer wrapper is drawn from a reel 11 over a spring loaded jockey arm 12 by means of a pair of continuously rotating feed rollers 15. A web 16 of inner wrapper is drawn from a reel 17 over a jockey 18 and the two superposed webs pass over a spring loaded wire loop 22, Fig. 2, through a gap 41 between an electromagnetic armature 25 and an anvil 23 to a pair of intermittently rotating rollers 28. Web 10 carries a series of marks spaced along the web which are detected by a light source 32 and photo-electric cell 31 receiving light reflected from the web. When a mark is detected by the photo-cell, the end of the two webs is correctly positioned for the wrapping operation and the electromagnet armature 25 is released by a relay so that a spring 39 is able to move the armature to clamp the webs between it and the anvil 24, feed rollers 28 slip on the web for the remainder of their rotation and knives 29, 30 sever the part to be used. When the clamp is operated the surplus web accumulating between it and the rollers 15 is taken up by wire loop 22 until a flat on one of rollers 15 engages the web when it is drawn backwards through the rollers by the spring loaded jockey arms. The armature is restored, to a position where the re-established field of the armature can hold it, by a pivoted lever 42 rotated by a shaft 46 and links 44, 45. This shaft also removes the lever from the armature before the clamp is again to be operated. According to the Provisional Specification, the electromagnet clamp may be switched into a circuit by a relay in response to detection of the marks on the web. Specification 262,588, [Class 100 (1)], is referred to.
