Title: Water-soluble polymers prodn. - by suspension (co)polymerisation of N-vinyl-formamide or -acetamide, addn. of hydroxylamine to remove residual monomer, and acid hydrolysis
Inventor: SATO SHIN-ICHI
IPC: C08F8/12
Filed: 1992-09-25
Abstract: Prodn. of water soluble polymers (I) is by suspension polymerisation of N-vinyl amides of formula CH2=CH-NHCO-R (II), (R is H or Me), or a mixt. of (II) and other water soluble vinyl comonomer(s), followed by acid hydrolysis. (III) is added after polymerisation and before hydrolysis. Water-insol. hydrocarbon solvent is pref. used as dispersion medium (IV), in amts. of 0.5-10, pref. 1-5, times the wt. of the initial aq. monomer soln.; pref. solvent forms an azeotrope with water, esp. cyclohexane. Initial aq. monomer soln. has concn. 5-95 (pref. 20-80) wt.%. The system also contains acrylonitrile as comonomer, 0.01-5 (pref. 0.05-1) wt.% non-emulsifiable oil-soluble polymer or surfactant as dispersion stabiliser (w.r.t. amt. of IV) and 0.1-20 (pref. 1-15) wt.% polymerisation stabiliser, pref. NH4Cl or CaCl2, esp. pref. NH4Cl, (w.r.t. total monomers). (III) is added in the form of a salt of HCl, H2SO4 or HNO3. 90% or more (pref.95% or more) of the original monomer(s) is polymerised. (III) is added after polymerisation, pref. in amts. of 0.05-10 mols. per mol. residual monomer(s), and the mixt. is then stirred for 0.25-4 hrs. at a temp. between room temp. and polymerisation temp.. The mixt. is hydrolysed in the presence of HCl, pref. at 20-150 deg. C, and at least 60% of the amide gps. are hydrolysed. USE/ADVANTAGE - Esp. as flocculating agents and paper treatment additives. Addn. of (III) significantly reduces the amt. of residual (II) in the polymerised mixt.. This prevents the modified or hydrolysed prod. from gelling after acid hydrolysis and thus facilitates the prodn. of water-soluble (I) in the form of good quality powder.

The outer surfaces of the jackets have cooling ribs or the two ends may be held by the outer rims of the rotor end-winding retaining rings. ADVANTAGE - Reduces bearing and rotor shaft heating.

Title: Mixing plant for granular material such as concrete with the addition of fibrous aggregates
IPC: B28C7/06
Filed: 1993-02-25
Abstract: A fibre-feed device which can be allocated in each case to the mixer and which has a screen as a feeder is provided for use in mixing plant for granular material such as, in particular, concrete with the addition of fibrous aggregates. Adjoining the screen is a batcher via which the singularised steel fibres are fed specifically and uniformly to the filling funnel and the delivery line arranged underneath. Reliable feeding into the delivery line is ensured by a nozzle-shaped injection opening or a nozzle-shaped delivery-air discharge. The length and diameter of the delivery line are dimensioned in such a way that the end of the delivery line can be inserted directly into the mixer, which then serves as expansion space. Reliable and uniform feeding of the individual steel fibres is thus guaranteed. <IMAGE>

Title: Five-axis gear-cutting machine for producing spiral gears, and method of operating the machine
Inventor: STADTFELD HERMANN J PROF DR
IPC: B23F23/00
Filed: 1993-04-24
Abstract: Spiral-toothed bevel or hypoid gears in particular are produced according to one of the known forming or generating processes on this fully automatic, electronically controlled gear-cutting machine. Through the use of axes required solely in terms of gear-tooth mathematics, this machine, apart from the spindles for tool and work gear, only requires three axes moving during the process without restricting its function. This results in a very simple and rigid machine construction. The method according to the invention shows that the plunge movement, relatively between tool and work gear, is carried out by a rotation of the headstock, which is thereby given a double function. The sequences of movement of the machine axes as a function of time are also virtually linear in order to produce the most complicated gear tooth systems, such as form-generated hypoid pinions. A considerable improvement in the stability and rigidity of the control process of the electronic control equipment can thereby be achieved. The preconditions for a favourable dynamic behaviour of the gear-cutting machine during the machining process are created by the reduction in the movable machine parts as well as by the simplification of the kinematic sequences.
