Abstract: In producing brewers' wort, proteolytic enzyme is added to a malt mash, the enzyme-containing mash is held at a temperature of from 35-40  DEG C. for a period of from 45-90 minutes, thereafter liquefied cereal grain is added to the enzyme-containing mash in a proportion of from 45-70% by weight based on the total weight of malt and cereal grain, and the temperature of the entire mass is raised to 65-75  DEG C., which temperature is maintained for a period of from 30 minutes to 60 minutes.  The proteolytic enzyme is preferably added in a proportion of from 0.16-0.25% by weight of the malt.  The liquefied cereal grain is preferably added to the enzyme-containing mash in a proportion of about 50% based on the total weight of malt and cereal grain, but whenever the liquefied cereal grain level is 55% or more, diastatic enzyme is included with the proteolytic enzyme added to the malt mash.  Cereal grains such as maize or rice may be employed.  Proteolytic enzymes mentioned are papain, ficin, bromelain, pancreatin, fungal protease and bacterial protease. Diastatic enzymes mentioned are bacterial amylase and high diastatic malts such as distillers' malt. Specified proportions of black roasted malt, dark, medium and light caramel malts, and malt syrup may be included in the wort to compensate for the significantly lower level of malt. According to an example, 250 g. maize grits and 11 g. brewers' malt in 900 ml. brewing water are held first at 70  DEG C. for 30 minutes and then at 95-100  DEG C. for 10 minutes, whereby the maize grits are liquefied To the mash tun are added 73 g. brewers' malt, 29 g. high diastatic malt, 25 g. soya flakes, 0.56 g. papain, 0.066 g. bacterial amylase, 4 g. malt syrup and 500 ml. brewing water.  The mash is held at 37  DEG C. for 60 minutes, the liquefied maize is then added to the mash and the temperature is then held at 70  DEG C. for 45 minutes.  The mash is lautered and sprayed with 1600 ml. brewing water.  The worts are transferred to a kettle and after the addition of 3 g. of hops, are concentrated to a volume of 2000 ml. by boiling.  The concentrated worts are then fermented and stored as is described in the example.

Title: Electric pulse transmission systems
IPC: G01S13/28
Filed: 1971-11-03
Abstract: 1322848 Pulse compression radar SIEMENS AG 3 Nov 1971 [9 Nov 1970] 51011/71 Heading H4D A pulse compression system in which received signals are heterodyned with a locally generated signal whose frequency is modulated according to a predetermined time function before being fed to a frequency dependent delay device. In a radar system transmitted pulses having a frequency-time characteristic 10 are reflected from a target and received as signals 11. These are mixed with a local oscillator signal 12 giving a resultant signal 13. The modulation gradient of signal 13 is independent of the time of reception being the sum or difference of the transmitter and local oscillator gradients (depending on whether the sum or difference frequency mixed signals are utilized). The compression device is thus designed to produce a satisfactory compression for the predetermined frequency spread of signal 13. However the centre frequency of signal 13 depends on its time of arrival and thus the average delay of the compression device is range dependent. This necessitates some compensation in any display device but may be used to separate overlapping pulses. The local oscillator signal may undergo several cycles during each transmitter period and the modulation of the transmitter and local oscillator may be changed during successive periods whilst retaining the same resultant modulation gradient. The modulations may not be linear but their resultant is preferably linear (Fig. 5, not shown).

[Also in Division F2] A two-speed gear for a steering mechanism provides high- and low-ratio steering. The gear comprises a planet carrier 48 splined to a steering shaft 40 and a ring gear 26 axially slidably splined to an extension 18 of a steering wheel 12 and engageable with clutch teeth 58 of the carrier for direct drive. The ring gear is shiftable to the right to mesh planets 68 to give a low ratio, the planets meshing a stationary sun 74. The teeth of the ring gear are wider than the spacing between the clutch teeth 58 and the planets so that the steering mechanism is locked during shift. The teeth 58 are bevelled at their ends adjacent the planets to facilitate shift, and the planets are slidable on their pins 66 and biased towards the carrier so as to yield axially should their teeth abut those of the ring gear. The ring gear has a groove 86 engaged by pins on a yoke 90 having offset skewed slots engaged by aligned pins 96 on a stationary housing 34. The yoke is fast with a shift lever 102 co-operating with an L-shaped gate in the housing, a spring 122 biasing the lever to each end of the gate, the offset skewed slots permitting a pivotal and rocking movement of the yoke 90 initiated by movement of the shift lever 102 along the L- shaped path to shift the ring gear axially to change the ratio.

The impurities are in particular free bromine or iodine and polybromides or polyiodides. The catalyst solution may be treated with a metal or alloy, e.g. with nickel shavings when a nickel catalyst is used, or it may be treated with an absorbent, e.g. active carbon, silica, alumina, clay and other porous materials. The treatment may be monitored quantitatively by titration with thiosulphate or qualitatively by the colour reaction with starch/water. In examples, a mixture of C 15 -C 18  alpha olefins is reacted with carbon monoxide in the presence of aqueous nickel iodide to produce a mixture of C 16 -C 19  carboxylic acids. Other processes mentioned are the carbonylation of olefins in the presence of alcohols, mercaptans, ammonia, amines or carboxylic acids to produce carboxylic esters, thioesters, amides or anhydrides, and the carbonylation of alcohols to produce carboxylic acids.

Abstract: 1335208 Rail vehicle bogies A MAUZIN P TRUFFART and F THAREL 3 Nov 1970 [5 Nov 1970] 52319/70 Heading B7L A bogie for a railway vehicle having an undercarriage 1 pivotally connected about axes 7, 8 to axle box guides 2, which receive axle boxes 3, by links 4, comprises a primary suspension stage in the form of chevron-shaped resilient rubber metal sandwich blocks 5 located between the undercarriage 1 and the guides 2 and having vertical flexibility but substantially transverse rigidity, and a secondary suspension stage in the form of vertically superposed resilient rubber metal sandwich blocks 6 located, in us, between the undercarriage 1 and the vehicle body and having a transverse flexibility which is greater than their vertical flexibility, there being two stacks of blocks 6 on each side of the undercarriage 1, the upper surfaces of these blocks 6 being inclined inwardly in a downwards direction thus forming the four faces of an imaginary inverted pyramid, the apex of which is located at the imaginary pivotal centre 0 of the bogie with respect to the vehicle body such that the blocks 6 control both the transverse movement and the rolling effect of the vehicle body. A control member 12 on the undercarriage 1 serves for extra control on the transverse movement of the body, the control member comprising resilient stops 26 carried on the bogie, plates 27 being fixed to stops 26 and co-operating with a rigid stop 23 supported on a vertical stack of blocks 24 which can be deformed transversely. The stop 23 can co-operate with a rigid stop 22 on the vehicle body, the two stops being separated when an unloaded vehicle body is placed on the bogie by virtue of their parallel surfaces which are inclined to the undercarriage 1. An initial transverse displacement of the vehicle body will be controlled by the blocks 6 alone until the stops 22, 23 come into contact, the resilient stops 26 then assisting the blocks 6 in resisting the displacement. Figs. 9 and 10, not shown, illustrate the action of the control member when the vehicle body is loaded. In Fig. 5, a resilient stop 30 on the bearing 4 assists the blocks 5 in resisting excessive vertical movement of the vehicle body with respect to the bogie, the stop 30 coming into contact with a counter-stop 31 on the undercarriage 1 when the blocks 5 have been sheared to a predetermined extent. Alternatively, a resilient spring member may be operatively connected to the chevron-shaped blocks to urge them downwardly in an unloaded condition thus creating an initial deflection which stiffens the suspension at this point (Fig. 6, not shown). At a predetermined load the spring member no longer acts to deflect the blocks.
