Abstract: Method for the prepn. of ammonium nitrate and phosphate (1) Finely ground phosphate ore is digested with HNO3, giving calcium nitrate and acid phosphate (2) Ammonia is added to pH 3-6, precipitating Ca HPO4 The pptd. phosphate is filtered off and may be dried and used as fertilizer. (3) Alt., the ppt. phosphate may be treated with more HNO3 etc. to give 'ammon-phos' (4) After filtering off the CaSO4, the soln. is concd. until almost an H2O free melt, and 'prilled', giving solid 'ammon-phos'. (5) The clear soln. from (2) is treated with NH3 and CO2, giving NH4NO3; The soln. is filtered, concd. and prilled, giving solid NH4NO3. (6) The CaSO4 isolated at (3) may be re-used to provide (NH4)2SO4 for recycling Thus all the Ca in the phosphate rock is converted to CaSO4, producing 'ammonphos' with a P2O5: N ratio 2:1, and ammonium nitrate.

Patent DE-2121460-A1 (DE)
Title: Moulding shoes with elastomeric soles
IPC: A43B15/00
Filed: 1971-04-30
Abstract: In a process for making moulded shoes an elastomeric shoe sole is moulded directly onto the upper and a strip of material is fixed to the lower edge of the upper together with mounting cord, the process being carried out in a segmented mould which is preferably deformed to allow precise placing of the upper in the mould.

Title: Mechanised asparagus peeler - clamping members, and transverse sliding peeling blades automatically following outline
Inventor: EBERT HANS-DIETER DR
IPC: A47J17/08
Filed: 1974-05-30
Abstract: The universal asparagus peeler has a clamping device (15, 17) with adjustable rotation for clamping both ends of an asparagus shoot (19) whilst a blade head (6) connected to an electric drive motor moves to and for along the clamping shaft (8). The blade head has at least two peeling blades (7) resiliently biased relative to each other and displaced across the clamping shaft. Thus during the work stroke of the blade head, the peeling blades which are perpendicular to the centre axis of the clamped asparagus shoot slide along the asparagus shoot following its contour by virtue of their resilient design and peel off about 5 to 8 mm. The clamping members (15, 17) can then be rotated slightly so that when the blade head moves back on its return journey, two more similar strips are peeled off.

Title: LV supply circuit for TV receiver - has horizontal deflection circuit equipped with controllable SC components
Inventor: RIECHMANN WERNER
IPC: H04N3/185
Filed: 1974-08-14
Abstract: Energy required during the horizontal deflection circuit operation is supplied by a constant voltage source through a variable charging inductance to the horizontal deflection circuit during line forward sweep, and is stored in capacitors. The inductance has a secondary winding to which a rectifier is connected. The inductance value is so adjusted, that during the charging phase a voltage maximum is generated across it, independent from load changes of the horizontal deflection circuit. Triggering pulses are derived from the inductance through a tapping for a controllable SC component. The rectifier is a triggerable SC component, to which the triggering pulses from the horizontal deflection circuit are applied.
