Title: Speed control system for DC motor - involves motor acting briefly as generator to obtain actual speed signal for difference control signal generation
Inventor: HOERNER HERMANN VON DIPL PHYS
IPC: H02P7/29
Filed: 1977-02-15
Abstract: The speed control system for a direct current motor, has its running time broken up into a sequence of alternate working and measuring intervals. During the measuring interval the motor acts as a generator whose output is used to generate a difference control signal for adjusting the speed. The ratio between the working and measuring intervals is fixed. The motor is in series with a switch controlled by a clock such that it alternates between working and measuring steps. The difference signal controls a pulse modulator for the motor power supply.

Abstract: Prodn. of pure (>99.5%) hexamethylphosphorotriamide (I) comprises first reacting POCl3 and HN (CH3)2 in an organic solvent to give crude (I), removing salts formed as by-prods. then evaporating off the solvent. The crude (I)'s then contacted for 1-5 hr. at 60-80 degrees, esp. 110-160 degrees C, with 0.2-6, pref. 0.4-2.5 wt.% (on crude (I)) of alkali hydroxide as a >=20% aq. soln. The treated mixt. is then fractionally distilled under reduced pressure. The crude (I) may be distilled (esp. continuously) and pref. only the residue is subjected to alkali treatment. Pure (I) is used as an absorbant for removing acetylene from reaction gas streams. Less alkali hydroxide is needed compared with known processes so there is less pollution of waste water streams. Yields of pure (I) in the fractionation are improved e.g. 97.6% c.f. 91.2% calculated on cruce (I).

Title: Immersion lance for treating molten metals, esp. steel - where lance is made using two tubes of different shape, preventing vibration and increasing lance life
Inventor: BREITZMANN KONRAD
IPC: C21C5/46
Filed: 1978-05-05
Abstract: The lance is employed for the injection of inert gases and/or addns. into the molten metal; and consists of an inner tube sepd. from an outer tube by a refractory mass; and a refractory sheath is used on the outside of tube. The two tubes pref. have a different cross-section, e.g. a round tube inserted in a square tube, esp. where tube is made by joining two U-channels together, the channels being made by continuous casting. The intemediate refractory mass may contain a tube used to inject gas into the molten metal if tube becomes blocked, or if a second carrier gas is to be used to feed an addn. into the melt. The lance is simple and inexpensive to make and can be used several times, thus lowering the cost of steel mfr.; an important feature is that the lance does not vibrate in use; such vibration can fracture the refractory sheath.

Title: Drying offset printing ink by IR rays - by selecting only effective section of spectrum to avoid damage to print
Inventor: WEINREICH PETER
IPC: B41M7/00
Filed: 1978-05-30
Abstract: In the drying of offset printing ink by infrared radiation, optimal effectiveness is achieved by filtering-out and/or reflecting such part of the infrared frequency range as does not, or only in relatively small measure, take part in the drying of the ink(s). This minimises excessive heating of the irradiated print and consequent potential damage to it, and also reduces necessary power consumption (hence costs) to a minimum. Moreover, the claimed process improves working conditions for operatives, as compared with some prior-art methods e.g. use of gas-fired hot-air drying ovens.
