Title: Single bath dyeing of cellulosic textiles with ice colours - using alkaline bath contg. coupling component; with subsequent addn. of diazonium salt
Inventor: HERTEL HASSO DIPL CHEM DR
IPC: D06P3/68
Filed: 1978-07-19
Abstract: A method for single bath dyeing of cellulosic textiles with ice colours, without an intermediate rinsing stage between the impregnation and development, comprises treating the material with an aq. bath contg. coupling component and an alkali, and, adding to the bath after the ptake of the coupling component onto the fibre, a soln. of a diazonium salt and opt. a quantity of alkali fixing agents to give a pH of 9-12.

Title: Rotary heat exchanger for power stations - has stator divided into sections to utilise natural sources at different temperatures
Inventor: SOELCH ROLAND
IPC: F28D19/04
Filed: 1978-09-26
Abstract: The heat exchanger has a circular stator (12) divided by internal plates (31, 31', 31") into three sections (62, 64, 66). Three different media at different temperatures flow through these.

Title: Ignition circuit for IC engine - has voltage pulse appearing when control transistor turns transistor switch for ignition coil off
Inventor: ROTH HELMUT
IPC: F02P5/155
Filed: 1979-02-16
Abstract: The ignition circuit has a control transistor (15) turning on to close a transistor switch (7) in series with the ignition coil's (6) primary winding (5). The transistor switch is opened when the control transistor turns off. Two capacitors (16, 37) produce a voltage pulse when the control transistor passes from conducting to non-conducting state. The voltage pulses are dependent on the speed of the engine. Below a given min. speed the voltage pulse is used to switch over an additional transistor (33) into the conducting state temporarily. This transistor is located in a shunt path (34) associated with the control transistor. The ignition time point during starting the engine approaches the upper dead point so that starting is realiable.

Abstract: A high carbon, heat and abrasion resistant, iron-base alloy having a final compsn. which includes at least 1% of one of Cr, V, Mo, W is produced by (a) atomizing a melt having an initial C content of 0.2%, (b) blending the powder from (a) with enough C particles to give a blend having a C content greater than the C content found at the iron-base alloy's eutectic point, thereby creating greater difference between the liquidus and solidus temps., (c) compressing the blend in a die at 2800 kg/cm2 and (d) sintering at a temp. between the liquidus and solidus temps. to produce a high density material. Prodn. of small size wear resistant articles from alloys which are almost eutectic. The C addn. enables liquid phase sintering to be carried out, by creating a wider top range between liquidus and solidus, thus the high density articles can be made economically by powder metallurgy. The addn. of 1-2 wt.% C has little effect on the properties of the resulting alloy.

IPC: C07C29/38
Filed: 1980-06-24
Abstract: In a new process for the prodn. 1,1,-trichloro-2-hydroxy -4-methyl-3-pentene (I) by catalytic thermal isomerisation of 1,1,1-trichloro-2- hydroxy-4-methyl-4-pentene (II) produced by catalytic reaction of chloral with isobutene, (a) the reaction of chloral with isobutene is carried out in the presence of an AlCl3 etherate as catalyst and (b) the isomerisation of the resulting (II) is carried out using 1,1,1,4-tetrachloro-2- hydroxy-4-methylpentene (III) as catalyst. (I) is useful as a synergist for herbicides. It is also useful as an intermediate for 2,2-dimethyl-3-(2,2-dichlorovinyl) cyclopropanecarboxylic acid, an acid component of synthetic pyrethroids. AlCl3 etherates do not react with chloral, so that the prepn. of (II) can be carried out by passing gaseous isobutene through a mixt. of chloral and catalyst. When isomerisation of (II) is catalysed by (III), reaction time is shorter without adversely affected yield.
