Title: Continuous brewing process
IPC: C12C7/20
Filed: 1963-09-20
Abstract: In the continuous production of hopped brewer's wort by heating wort in admixture with hops, the heating is accomplished by recycling part of the hopped wort through a swept surface heat exchange pump to raise the temperature of this recycle wort to above its atmospheric boiling point e.g. to 220-250 DEG F. and returning the hot recycle to the body of wort beneath the surface thereof, so that the body of wort is maintained at a rolling boil. In the several embodiments (1) a stream 10 (Fig. 3 not shown) of hopped sweet wort is supplied directly to the insulated boiling kettle 11, (2) the sweet wort and hops are introduced into the recycle wort (Figs. 1 and 2, not shown) (3) the sweet wort is introduced into the recycle wort but the hops are added directly to the kettle and (4) the hopped wort product is drawn off from the recycle line either in advance of, or following, the heat exchange pump instead of directly from the kettle. Regarding embodiment (2) above, the hops are preferably added to the recycle wort prior to its passage through the swept surface heat exchange pump. The kettle may be maintained at a pressure between atmospheric and the pressure of the hot recycle wort e.g. at 19 lbs. per sq. in gauge pressure. In general, four volumes of hopped wort are recycled per volume of sweet wort added. Examples are disclosed. It is stated that since the kettle does not contain any heat transfer surfaces it is unnecessary to utilizesuch expensive materials as copper in its construction.

Title: Method and apparatus for determining the quantitative relationship between components
IPC: G01N23/08
Filed: 1960-11-01
Abstract: 954,839. Chemical analysis utilizing X or γ rays. J. J. MADIGAN. Nov. 1, 1960, No.37522/60. Heading G1A. Relates to a method of determining the relative proportions of two organic components in a product composed mainly of these components in which one of the components is a protein material and the other component is a lipid or carbohydrate containing less than 1% by weight of nitrogen and having a total percentage by weight of carbon and hydrogen in excess of 50%. According to the present invention the relative proportion of the two components is determined by measurement of the transmission of X- or γ rays of energy not exceeding 50, 000 electron volts through a sample of the product and comparison with the transmissions through samples of known but differing proportions of these components. The invention may be used to determine the relationship of lean to fat in meat, of butterfat to other components in milk and of oil to other components in soy beans and cotton seeds. An apparatus for determining the proportions of fat and lean in meat comprises a lead chamber 10 in which is a radiation source such as an X-ray tube 11, a container 12 of the meat sample 13, and a detector such as an ionisation chamber 14 whose current is measured by an electrometer 31. With a constant potential applied to the X-ray tube the radiation emerging from each of a range of samples of constant thickness and differing known proportions of lean and fat is measured to obtain an empirical graphical relationship between the lean and fat content versus emergent radiation and this is used together with measurement of the radiation emergent from an "unknown" sample of the same thickness to determine its lean-fat composition. The radiation source may also be a radio-active isotope and the Specification lists those suitable, and the detector may be a Geiger- Muller tube or scintillation crystal. Measurement may also be made by varying either the X-ray tube voltage or detector distance from the sample or by interposing filters of known properties between the source and sample, to obtain in any of these cases a constant level of radiation at the detector. The Specification contains a discussion of the optimum values of radiation intensity for such measurements and gives experimental results.
