Title: Improvements in processes and apparatus for boiling and hopping brewers wort
Inventor: WATTS PERCY HENRY
IPC: C12C7/20
Filed: 1961-11-01
Abstract: <PICT:1035621/C6-C7/1> In a continuous con-flow process for boiling and hopping brewers' wort, involving a boiling zone A, a hopping zone B and a separation zone C; the wort is passed through at least the boiling zone and the separation zone at a controlled rate; the temperature of the wort in the boiling zone is raised to and maintained at boiling point e.g. by steam jacketing 9 or electrically, for a controlled period to induce a hot break; hops are passed through the hopping and separation zones at a controlled rate and are thoroughly mixed with extracting liquor (wort or water) in the hopping zone to form a dispersion which is maintained at the requisite temperature for extracting the desirable substances from the hops; and the boiled wort and the hop dispersion are passed into the separating zone for separation of spent hops from the hopped wort.  Either the wort passes successively through all three zones and constitutes the extracting liquor in the hopping zone, or the wort passes through the boiling and separating zones, water constitutes the extracting liquor and hopping of the wort takes place in the separation zone.  The separation zone as illustrated may be replaced by the belt-type of filter described in Specification 943,811.  Recycling of controlled amounts of liquid in and between zones may be carried out as indicated in Fig. 4 (not shown).

Title: Apparatus for relieving pain and discomfort
IPC: A61M21/00
Filed: 1959-11-18
Abstract: 896,423. Ear instruments. GARDNER, W. J., and BOLT, BERANEK & NEWMAN Inc. Nov. 18, 1959 [Dec. 10, 1958], No. 39192/59. Class 81 (2). Apparatus for relieving pain during dental operations comprises a pair of earphones which mask ambient sounds, means for supplying audible noise signals and means for supplying audible intelligible signals to the earphones, and volume controls for the noise signals and the intelligible signals, respectively. Each of the pair of earphones 17, 17<SP>1</SP> is connected through an amplifier A, A<SP>1</SP> and mixing resistances R 1 , R 2 , R 1 <SP>1</SP>, R 2 <SP>1</SP> with a generator 7 of intelligible stereophonic audible signals, e.g. music, and a noise generator 2. A filter 3 determines the frequency band of the noise received. Each generator is associated with attenuators 12, 12<SP>1</SP>, 10, 101 and potentiometers 6, 6<SP>1</SP>, 13, 13<SP>1</SP> by which the sound reaching the earphones may be adjusted. A switch S 2  is ganged with sliders 8, 8<SP>1</SP> of the noise generator potentiometer so that for low intensity levels of the noise received the output leads 14, 14<SP>1</SP> of the noise generator are short-circuited to prevent noise reaching the other generator. Another switch S 3  enables the operator to insert resistances R 3 , R 3 <SP>1</SP> in the circuit to the earphones to reduce the intensity of sound reaching the earphones sufficiently for the patient to be spoken to using a microphone 37. Signals of a level 100 db. above 0.0002 microbars may be obtained from the apparatus.

The two rasters are so adjusted that they have the same raster constant in the final image plane and the light areas of the first raster lie in the middle of the light areas of the second - ster. The optical density of the dark areas of the second raster is equal to the exposure range, expressed in logarithmic units, of the electro-photographic surface. The raster tone values of the first and second rasters lies between 60 and 90% and 30 and 60% respectively.
