Title: Anhydrous carboxylic or halo:carboxylic acid alkali salt prodn. - by reacting the acid with a sub-stoichiometric amount of alkali alcoholate
Inventor: REISINGER KURT DR
IPC: C07C51/41
Filed: 1978-11-21
Abstract: In the prodn. of anhydrous alkali salts of 2-8C aliphatic carboxylic or halocarboxylic acids from the corresp. free (halo)carboxylic acids by reaction with alkali alcoholates, the reaction is not taken to the theoretical endpoint but is terminated at ca. 97-98% of this value, and the alcohol formed is completely removed by addn. of an inert solvent with simultaneous distn., before the isolation of the (halo)carboxylic acid alkali salt. (Halo)carboxylic acid alkali salts are useful as intermediates for organic and pharmaceutical prods. Many are themselves pharmaceutically active. The prods. are highly pure and consequently have improved stability; halocarboxylic acid alkali salts produced by the new process display no tendency to polycondens.

Title: Mandrel changing on hot rolling mill mfg. metal tube - where rolled tube is quenched in water tank, which is partly drained to facilitate mandrel replacement
Inventor: UHLMANN OTTO
IPC: B21B25/06
Filed: 1979-03-05
Abstract: Parent patent described the skew rolling of tube. The initial billet is driven by the rolls over a piercing mandrel, and both the rolled tube and the mandrel are located in a water tank. After each rolling operation, the mandrel is retracted into the front part of the tank for inspection and replacement if required. In this addn. only the front part of the tank contg. the mandrel is drained of water while the mandrel is changed; and the front part of the tank is pref. fitted with isolating shutters facilitating emptying and filling. For example, a red-hot Cu tube is rolled and fed directly into a water tank to minimise oxidn. of both the bore and outer dia. of the tube. The scale entering the water makes the latter muddy so it is difficult to see if a new mandrel is propery aligned on the mandrel rod. The present invention eliminates this problem.

Title: Optical fibre connection for opto-electronic component - uses manual coarse adjustment and complementary opto-electronic component for fine adjustment
Inventor: KALMBACH ULRICH
IPC: G02B6/42
Filed: 1979-07-26
Abstract: The connection has one end (3) of the optical fibre (1) inserted in a bore in a cup-shaped element (5,6). The edge of the latter is in sliding contact with an annular element (9) which encloses the optoelectronic component (10), with preadjustment of the cup-shaped element (5,6) allowing the end (3) of the optical fibre (1) to be moved in three orthogonal planes relative to the optoelectronic component (10), without touching it. A second optoelectronic component (11), complementary to the first is positioned at the opposite end of the optical fibre (1) with its output signal monitored to determine the optimum coupling position of the first end (3) with the first optoelectronic component (10). The initial preadjustment is made visually by forming the cup-shaped element (5,6) as a central hollow pin (5) sliding within a ring (6). The latter is released after the subsequent fire adjustment using the second optoelectronic element (11).
Patent DE-2931867-A1 (DE)
Title: Transformer for transistor operated inverter - has control windings linked with part of the core by passing through holes in it
Inventor: SCHMITZ NICHOLAS ARTHUR
IPC: H01F19/04
Filed: 1979-08-06
Abstract: The transformer can be used in transistorised inverters operating at an output frequency of several tens of kHz. Powerful turn on and turn off pulses are applied to the switching transistor. The transistor base current is reinforced by windings which pass through holes in the transformer core. One winding is in series with the load current in the primary coil. The other, linked with it, is in the base-emitter circuit of the switching transistor. The holes are arranged such that the windings do not link with the main flux when the core is unsaturated. The windings thus act in current transformer mode. As the main flux increases the positioning of the holes gives selective core saturation such that the main flux is forced to link the windings. The induced base current thus suddenly collapses and turns the switching transistor off.

Title: Aniline prodn. by catalytic amination of phenol - in vapour phase using preheated ammonia to vaporise phenol, preventing blockage
Inventor: GIEBELER EBERHARD DR
IPC: B01J12/00
Filed: 1980-04-05
Abstract: Amination of (alkyl)phenols (I) is carried out in the vapour phase in the presence of a solid catalyst, the charge being vapourised under pressure at 300-600 deg.C, opt. with introduction of inert gas. The novel feature is that NH3 vapour, preheated to 100-500 deg.C, is allowed to flow upwards from the bottom of a vapouriser and mix with the (I), which is introduced through a distributor at a higher point. The mixed vapour is transferred to the reaction zone. The NH3/(I) molar ratio is 7-30:1. (I) mixed with toluene can be used as charge. Loss of yield and selectivity are reduced and mutual vapourisation prevents the formation of residues and plant shot-downs due to the these. The process is used for the prodn. of (alkyl)anilines.
