Title: Marine propeller for arctic waters - with blades separately attached using shearing bolts to avoid drive shaft damage
Inventor: GRODDECK KARL-HEINZ DR ING
IPC: B63H1/20
Filed: 1974-08-17
Abstract: Each blade (2) of the ship's propeller is mounted separately to the hub using a mounting flange and a set of mounting bolts (3). The material of the bolts, and the tightening torque, are carefully chosen so that the bolts shear when a set resistance is left by the blade. This enable s the blade to shear off when encountering icefloes with inclusions of stones, or of a thickness to cause damage to the propeller shaft mounting. In this way only one propeller blade is lost and the ship can still be moved to safety. Spare blades can be carried, and these are easily fitted either by using divers or by trimming the ship to lift the stern out of the water.

Title: Activated sludge treatment to eliminate phosphates - by mixing with sludge and aerating
Inventor: LEVIN GILBERT V
IPC: C02F3/30
Filed: 1974-09-03
Abstract: An activated sludge treatment eliminates phosphates from sewage by mixing with sludge and serrating until the microorganisms have absorbed phosphates. The phosphate are released in a settling zone containing an anaerobic sludge layr. When the soluble phosphates have migrated into the upper part of sludge to form a liquid layer, this layer with its phosphate content is removed and the low-phosphate sludge is recycled. The phosphates are released and the high - phosphate aqueous phase is separated from a low - phosphate sludge directly in the settling zone. This saves the time and the apparatus for the separate treatment of a high-phosphate sludge.

Title: Demodulator for HF carrier FM with two different frequencies - uses oscillations converted to rectangular pulses, counted and applied to matrix which delivers corresponding signal
Inventor: FUHRMANN HANS DIPL ING
IPC: H04L27/156
Filed: 1976-07-07
Abstract: The received high frequency oscillation is converted into rectangular oscillation, synchronised by pulses of a generator and applied to a period counter. Its output is connected to a programmable matrix which determines, over how many periods the high frequency must be measured. The generator pulses are applied to a counter whose reading, after reaching the set number of high frequency periods, is applied through the matrix to a store. Then after a half-cycle delay the counters are erased and a further matrix with two outputs, following the stores, is interrogated on whether the reading has reached a value corresponding to one of the two signal frequencies. In positive instance a corresponding signal appears at one of the two outputs.

Title: Cellulose of low lignin content - is obtd. by treating with a soln. of low acid content which is then increased by introducing liq. sulphur dioxide
Inventor: SCHADLER REINHOLD
IPC: D21C3/26
Filed: 1976-09-10
Abstract: Method comprises, treating wood chips in a first stage with an acidic soln. contg. 5 wt.% but not less than 2.5 wt.% SO2 (2.9-4.9 wt.%) and a mole ratio of SO2 to MgO or CaO 2:1 to 3.5:1 (2.4:1 to 3.3:1) for 15-90 min (30-60 min) at a temp. of 45-90 degrees C (55-80 degrees C), feeding liquid SO2 to the pulp until the total SO2 content of the treatment soln. is 6-10 wt.% and the acid content has been increased, boiling in a second stage at a temp. of over 110 degrees C to finish the pulping process, and treating the pulp subsequently in known manner to give cellulose. Before treating the wood chips in the first stage they are subjected to a cold liquid impregnation under pressure for 3 times. The first treatment stage is carried out at a temp. of 70-80 degrees C (75 degrees C) and the acid soln. contains 4.0 wt.% SO2 and the mole ratio of SO2:MgO or CaO is 2.5:1 to 2.8:1. About 20-50 m3 soln. is taken off after the first stage. In the second stage the treatment soln. has an SO2 concn. of 6-8 wt.% (6.5-7 wt.% or esp. 7 wt. %) and liquid SO2 is fed to the soln. at a temp. of 60-90 degrees C (75 degrees C). The pulp is boiled in the second stage at 120-170 degrees C (130-150 degrees C). When the 2nd stage has been completed gaseous SO2 is taken off by expansion and liquified and returned to the process. Spent acid liquor is treated order to recover SO2. Process uses 15% less SO2 than known methods which reduces pollution problems. A higher cellulose yield is also obtained.
