Title: Improvements in or relating to the clarification of beer
Inventor: SHALER RICHARD GIBSON
IPC: C12H1/044
Filed: 1963-07-11
Abstract: Beer produced by a fermentation of an aqueous extract from grain is clarified by contacting the beer after fermentation with about 120-500 parts per million of a swelling gelling clay in substantially dry form.  A clay of the montmorillonite group, such as hectorite, is suitable.  According to an example, to fermented beer there was added 200 parts per million of substantially dry, powdered hectorite employing a flock gun operating under a pressure of gaseous carbon dioxide of about 40 lbs. per sq. inch in excess of the beer line pressure.  Concurrently, 19 parts per million of gaseous sulphur dioxide, 3000 activity units of bromelin per 100 barrels of beer and 2000 activity units of papain per 100 barrels of beer were introduced into the beer.  The treated beer was allowed to rest for five days and then was decanted from the quite negligible quantity of sediment, which barely covered the bottom of the tank.

Title: Improvements in electronic musical instruments
IPC: G10H1/00
Filed: 1960-08-11
Abstract: 932,303. Electrophonic musical instruments. K. A. MACFADYEN. Nov. 7, 1961 [Aug. 11, 1960], No. 27806/60. Class 88 (2). An electrophonic musical instrument comprises a multivibrator (or other relaxation oscillator) V3 which is tuned independently by means of keyboard contacts 37 controlling resistors, an octave switch 3b controlling condensers and variable resistors P4, P5 for transposing. There are controls also for vibrato, attack, volume, timbre and portamento. Vibrato.-An oscillator V1 feeding a cathode follower V2 provides a frequency vibrato, the amplitude and frequency of which is controlled by potentiometer 1a, 1b. Timbre.-The output from multivibrator V3 containing both odd and even harmonics drives an Eccles-Jordon flip-flop to transmit alternate positive and negative pulses confined to odd harmonics. A pentode V5 suppresses the negative pulses to a degree controlled by a biasing contact 4a and thereby reintroduces even harmonics when required. A formant circuit in the anode circuit of pentode V5 comprises two resonant circuits the natural frequencies and the damping characteristics of which are controlled at 5a, 5b, 5c, 5d. A phase inverter V6 links the pentode V5 to a push-pull output stage comprising two tubes V7. Tubes V7 are normally biased beyond cut-off but are enabled by keyboard signals transmitted through an attack controlling circuit 8. A three-stage, adjustable, resistancecapacity low-pass filter 9b is connected to the output stage. Attack.-When any key contact 37 is operated, a voltage is applied to the grids of tubes V7 under the control of switches 8a, 8b, which control the time constant of the circuit. The key contacts are so arranged that the oscillator V3 starts before a control voltage is applied to the output tubes V7. Volume control.-Volume is controlled by a stepped level control 9c and a potentiometer 9a. Portamento.-In an alternative arrangement. Fig. 4, the timing of multivibrator V10 is controlled through key contacts S1, S2, S3 &c. When a key contact is closed, a selected voltage is applied through a delay circuit to cathode follower V 11 which in turn controls the frequency V10. Condenser C10 and variable resistor R16 in the delay circuit cause the multivibrator to glide between successive notes. Variable resistors R11, R14 are used for transposition. Condensers C11 are varied for octave switching.
