Title: Improvements in and relating to a filtering medium for use in brewing beverages
IPC: B65D85/804
Filed: 1956-01-31
Abstract: A filter medium for use in brewing beverages is non-porous until it has been treated with the hot water used in the brewing. The member as used in brewing coffee or tea is rendered non-porous by a thin coating of an edible water soluble agent which dissolves when the hot water is added to the ground coffee beans, the time taken for the dissolution permitting the hot water to begin extracting the soluble constituents of the coffee before filtering commences.  The coating may be on one or both surfaces of a filter paper and different materials may be used for them.  Sodium carboxymethyl-cellulose, methyl cellulose, starch, glucose, various gums, polyvinyl alcohol and solid paraffin are examples of materials mentioned.  Instead of a coating, the surface of a filter paper may be compacted by repeated blows from a hard member to become non-porous until expanded by the hot water treatment. Numerous examples of coffee brewing and one of tea are given. Ground egg-shell or chicory may be added to the coffee to vary its flavour.ALSO:A filter medium for use in brewing beverages is non-porous until it has been treated with the hot water used in the brewing.

A deep-field arrangement for an optical objective comprises in combination with the objective an approximately afocal member located in a position in which there is negligible zonal segregation of the field rays and having concentric zones arranged to give different effective lengths for the ray paths of different parts of the image-forming beam, where by the individual parts of the beam have approximately the same equivalent focal lengths but different flange back focal lengths, the distortion introduced by the afocal member being approximately corrected by giving a slight curvature to at least one of the surfaces of the afocal member. Fig. 1 shows an objective A combined with a plate formed of two zones C<SP>1</SP>, C<SP>2</SP> of different thicknesses coaxially located in the lens mount A<SP>1</SP>. The effect of this plate is to displace the plane B in which distant objects are focused. Such rays passing the portion C<SP>1</SP> being focused at B<SP>1</SP> and the rays passing the portion C<SP>2</SP> being foeused at B<SP>2</SP>. By ensuring that the individual 'parts of the beam have approximately the same equivalent focal lengths the images are of approximately equal magnification and the image of a nearer object formed by light passing the portion C<SP>2</SP> may coincide with the image of a distant object formed by the ;portion C<SP>1</SP>. The plate may be formed by joining the plates together face to face only connecting two or more annular sections concentrically. Alternatively only the central portion C<SP>1</SP> may be used, supported by a threelegged spider in the mount A<SP>1</SP>. The plate shown is for use in conveying light. When the plate is to be located within the lens in a position in which the beam is diverging, the plate is arranged to have its maximum thickness at the periphery and minimum thickhess at the centre.

Filed: 1920-02-06
Abstract: 138,869. Barbet et Fils et Cie, E. Feb. 8, 1919, [Convention date]. Rectifiers. - The vapours from a rectifying column A are led to a single tubular condenser B instead of the separate condenser and cooler hitherto used The condensate formed in the condenser B is divided into two parts, one serving as a reflux in the rectifier A, and the other constituting the distillate. The reflux portion is heated by heat-exchange with the fluids in the rectifier before it is led on to the upper trays of the rectifier. In rectifying alcohol &c., the heating of the reflux is effected by passing it from a header M through coils immersed in the liquid on the trays, and the heated reflux is collected by a header N and led to the top of the column. The remainder of the condensate flows through a valved pipe d to the test-glass D. In other cases, the heat-exchange is effected in a single tubular apparatus in the top of the rectifier. Cooling-water is supplied to the condenser B, it may be, under thermostatic control, in such quantities as to prevent the formation of incrustation; in the rectification of toluol, xylol, petroleum, &c., boiling of the water is entirely suppressed. The rectifying plant may be continuous or discontinuous, and may be arranged for " pasteurization " of the distillates.

Abstract: 1,025,063. Air conditioning. K. E. MERCKLE. Jan. 24, 1963, No. 3760/63. Heading F4V. [Also in Division B2] An apparatus for purifying and sterilizing room air comprises a cathode element 2 in the form of a metallic foil or grating attached to a wall or ceiling of the room and connected to a direct current source, the cathode element attracting foreign bodies present in the air and generating negative ions and radiating them into the surrounding atmosphere. Perforated plates or tiles 1 are interposed between the cathode element and the wall or ceiling and are made of dielectric insulating material which prevents radiation of the ions in the direction of the wall or ceiling. A protective grid-like covering element 3 is provided over the cathode. Sterilization of the air may be further increased by the addition of ozone which may be produced either separately and introduced into the air being purified or by setting up an electrostatic field between the cathode 2 and the element 3 which then becomes an anode, the passage of the air through the field resulting in the production of ozone. In the latter case, one of the elements 2, 3 may be adjustably movable relative to the other. Alternatively, the elements 2, 3 may be at a fixed distance from each other and a third movable cathode or anode is located between them. Further sterilization may be obtained by the incorporation of an ultra-violet light generator and/or radio-active elements to act directly on the air being purified. The ultra-violet light generator and the ozone generator can be employed simultaneously or independently.
