Title: Process for the preparation of beers weak in alcohol
IPC: C12G3/02
Filed: 1930-05-12
Abstract: Beers poor in alcohol are prepared from wort having about double the addition of hops usual with top fermenting beers (for example, 2 lbs. instead of 1 lb. of hops to each pound of malt). The wort is fermented for a normal length of time with top fermenting yeast and is allowed to stand for the normal time.  The wort may be prepared from only one-half the usual amount of malt, but with the customary amount of hops.  Shortly before bottling the beer may receive an addition of sugar, preferably in the form of starch syrup, and is then sterilized and filtered.  After repeated use the yeast becomes immune to the retarding influence of the increased amount of hops and should be replaced by one from a wort poor in hops.  Examples are given.

Title: Device for actuating electric switches
IPC: H01H3/32
Filed: 1927-06-02
Abstract: 272,498. Maschinenfabrik Oerlikon. June 14, 1926, [Convention date]. Oil switches; automatic circuit-breakers; electric motor actuation.-Switches of the kind which are actuated electrically by means of a gear train, are provided with a release device controlled by a member mounted on and driven by the shaft carrying the final member of the train the device being adapted to uncouple the switch from the driving device if the latter fails during switching-on. This prevents arcing due to the slow opening of the switch in view of he insufficiency of the force of the return spring and switch apparatus. The motor 1 actuates the switch lever 5 and switch 7 through a cam 4 and gearing 2, 3, the switch being shown in the " on " position and arrow a indicating the closing direction. If the driving force fails during switching-on the return spring 8 rotates the shaft counter to the direction a and the lever 9, which is frictionally mounted on the shaft, moves up to the stop 11 and by means of the members 12, 13 releases a undirectional coupling 6 to open the switch. Alternatively, the lever 9 may close the circuit of the release magnet 14 by means of a contact device similar to the release relay 15 which is preferably separately excited. Instead of the friction drive, the lever 9 may carry a pawl which is engaged by a ratchet fast on the shaft when the latter begins to rotate to open the switch. Alternatively as shown in Fig. 3 the lever 9 has an arm with a tapering face on which rests a ball 19 so that counter rotation of the shaft wedges the ball between the tapered face of the arm and the hollow cylinder 18 to release the switch.

Classes 55 (i) and 55 (ii) In a process for the generation of fuel gas from a carbonaceous solid, coal, coke or oil shale from a hopper 2 is mixed in particle form with water to form a slurry in a mixer 4 and is passed by a pump 7 through a heating coil 8 in which the liquid is vaporised and the dispersion attains a speed of at least 60 feet per second to disintegrate the coal as in the parent Specification ; the steam and powdered coal so formed are passed at 600‹-1400‹F. through a conduit 9 to a methanisation vessel 10 in which a turbulent fluidised bed of carbonaceous particles at 900‹-1800‹F. is formed and hydrogen and carbon monoxide are introduced through the conduit 9, the methanised gas and volatilised constituents of the coal being drawn off at 12. Char from the vessel 10 is withdrawn through line 17 and introduced into a gasification vessel 18 with unobstructed flow to which oxygen and steam at 620‹F. are added from a pipe 19, the hydrogen and carbon monoxide so formed passing at 2000‹-3000‹F. through the conduit 9 to carry the powdered coal to the vessel 10. The vessels 9 and 10 are operated at a pressure of 150-750 lbs. per sq. in., the vessel 10 being run at a lower pressure and having a cooling coil 11. The methanised gas passes through the pipe 12 to a dust separator 13, the fine particles from which are added through line 14 to the coal, and the hot gases pass through pipe 15 into heat exchange with the coil 8 containing the coal slurry. The gases pass to a pipe 16 for removal of water, oils and tar. Heat from the gasification zone may also be used to heat the slurry. Iron oxide as catalyst for the methanisation and fluxing agents for the ash such as lime, silica or alumina may be added to the slurry. Slag is removed as a liquid from the gasifier 18 at an outlet 20. Some of the vapour or of the solid may be removed from the slurry after passing through the heating zone, and the steam so withdrawn may be passed to the gasification zone. The slurry may be passed in indirect heat exchange with the fluidised bed of char in the methanisation zone. Specification 651,370 is referred to.

The device shown in Fig. 8 comprises three parallel rows of transducers 21, 22, 23 two of which 22, 23 are inclined to the body surface in use, the other 21 being perpendicular. Oscillator 10 energizes the three groups successively through switching unit 9 and similar unit 12 applies the echo signals from successive transducers through time-dependent gain amplifier 13 to detector 14 and intensity modulator 15 of C.R.T. 7. Since two of the groups are inclined, the X- and Y- deflection voltages are modified when these groups are active. Time base 17 output is multiplied by sin α and cos α in amplifiers 26, 25 and passed to the Y deflection plates through adder 28 and the X deflection plates respectively. Adder 28 introduces a D.C. level corresponding to the transducer position from step generator 16. If the three rows are displaced longitudinally, an extra shift is introduced by member 27. In a simplified arrangement (Figs. 1-4, not shown) only one perpendicular row is used, thus obviating the need for the co-ordinate transformation in the deflection voltages.
