Abstract: Process for repeated batch production of azo dyes, consisting of two chemical reactions, viz. diazotisation of the active component and coupling the diazo compd. with the passive component; characterised in that in each batch a constant amt. (V1) of the soln. or suspension of the appropriate component is charged to one of the two reactions, the concn. of the appropriate component varying in the range (K1 plus-or-minus a), and either a smaller amt. V3 V2. K1-a./K1 K2-b/K2 or a larger amt. V4 >=V2. K1+a/K1 . K2+b/K2 of the soln. or suspension of the remaining component is automatically charged to the second reaction, the concn. of the remaining component varying in the range K2 plus-or-minus b, wherein V2 is the amt. corresponding to the theoretical consumption which refers to the amt. V1 in maintaining the concns. K1 and K2, and wherein the choice of V3 or V4 is regulated automatically according to the amt. of soln. or suspension of the diazo compd. remaining after the preceding coupling.

Patent DE-2129213-A1 (DE)
Title: Increasing capacity of cheese - producing plant - by using protein - enriched milk
Inventor: SCHULZ MAX ERICH PROF DR
IPC: A23C19/05
Filed: 1971-06-12
Abstract: Part of skimmed milk soured with cheese-producing microorganisms is subjected to centrifuging to separate sour casein or rennet-soured casein. The centrifugate is de-soured, the rennet activity is restored, and the product is added to the remaining part of skimmed milk to increase its protein content before the addition of rennet. Thus, yields are increased, and the process is substantially accelerated, because microorganisms and enzymes are introduced in a large quantity into the second portion of the skimmed milk.
Patent DE-2155901-A1 (DE)
Title: Drying of cracking gases - contg olefins by glycols which are stripped with inert gas before regeneration
Inventor: KRUIS AUGUST DIPL CHEM DR PHIL
IPC: C07C7/00
Filed: 1971-11-10
Abstract: The glycols, charged with water and hydrocarbons from the drying process, are stripped with inert gas at 120-180 degrees (145-165 degrees)C before heating to the high temp. required for complete de-watering. The stripping medium is pref. superheated steam, which after heat exchange with the regenerated glycol, is blown into the pipe carrying the charged glycol from the drying process. Subsequent dewatering of the glycol is pref. assisted by stripping with a water-free inert gas. The initial stripping removes olefins (mainly cyclopentadiene) from the glycol.

The mould is then closed and the next section moulded intimately bonding itself onto the previous part. A continuous strip of the required length can thus be formed by additional moulding of sections.
Patent DE-2236022-A1 (DE)
Title: Enclosed clarifier tank for circulating mixture - with combined settling acceleration
Inventor: SCHULZ HERBERT

Title: Dust filter for brake lining mfr. - having two vertical perforated screens in housing, followed by bristle screen
Inventor: ERKOL FUAT
IPC: B01D45/08
Filed: 1973-06-14
Abstract: Filter to remove dust particles from air stream has central feed pipe for dust laden air the lower portion of which has a series of perforations and the base of which dips into an oil filled sump. This inner pipe is surrounded by a further perforated screen also dipping into the oil sump. These two sections are enclosed in a cylindrical housing which contains the oil. This has a cover and two further perforated screens. The central pipe is sealed on these upper covers etc. Above the lower screen is a disc shaped plate of the same dia. as the screen, also sealed onto the pipe. fixed by screws onto this plate is a ring of bristles which forms a fine screen to trap dust passing the initial screens. Air flows down central pipe and the coarse screens cause the bulk of the dust to collect on them and fall into the oil, which can be waste oil. Fine dust is removed by the bristles and the air then leaves via perforations. Used for removing dust formed during the cutting of brake shoes.

Title: Road vehicle steering control mechanism - to compensate for the effects of intermittent side winds using pressure gauge signals
Inventor: MAISCH WOLFGANG DR ING
IPC: B62D37/00
Filed: 1973-06-22
Abstract: A differential pressure gauge receives continuous and simultaneous pressure signals from suitable points one on each side of the vehicle. The pressure from each side operates upon a separate diaphragm in its own chamber, both diaphragms being attached to a central control rod. By allowing slow equalisation of pressure on the two sides of each diaphragm the effect of a steady wind is nullified. Movement of the central control rod is applied through a servo system to the steering mechanism.

Title: Container for soft drinks - has drinking tube held inside it in elastically bent position by its cap
Inventor: EISELE ROLF
IPC: B65D77/28
Filed: 1973-09-06
Abstract: The bottle is for soft drinks and includes a removable cap enclosing its opening and a drinking tube inserted in fluid of the bottle. The drinking tube, which is longer than the depth of the bottle, is held in the bottle by the cap in elastically bent position. When the cap is removed the drinking tube assumes its straight position and projects with its top end through the bottle opening. The top part of the drinking tube is bent downwards and is contacting with its bent top bottom surface of the cap and its downward projecting length is greater than the diameter of bottle opening. Between the downwards projecting part of the tube and its remaining length is provided a detachable connection which is not preventing positioning of the tube against opening of the container.

Title: Tricone roller bit seal - with O-ring on conical seat urging L-section sealing ring against roller shoulder
Inventor: SCHUMACHER JUN PERCY WILLIAM
IPC: E21B10/25
Filed: 1973-09-06
Abstract: A tricone roller bit has cutter rollers supported in a bearing, with a sealing ring around the spindle. The sealing ring (plastics or metal) has an inner contoured face and an outer sealing face. An O-ring (rubber) acts on the contoured face and urges the sealing face against a sealing shoulder of the outer roller. This requires less space in an axial direction so that more space is left for a stronger bearing. The seal acts also as a safety release valve.
Patent DE-2347284-A1 (DE)
Title: Support and fixing plate for mounting electric components - has rows of holes along edges allowing arbitrary mounting on rails, in for e.g. switchboards
Inventor: ANDREAS HUGO
IPC: H02B1/04
Filed: 1973-09-20
Abstract: The support and fastening plate for mounting electrical components, such as relays etc., in a switchboard housing has a row of equally spaced holes along each long edge to enable the rectangular plate to be mounted almost arbitrarily on support rails inside the switchboard housing, or attaching to parts that fit inside the switchboard housing. The two rows of holes allow the plate to be positioned on the support rails to an accuracy equal to the spacing between holes. The holes, therefore, avoid the necessity of drilling fastening holes or at least reduce the amount of work involved if such holes have to be drilled.

Title: Loudspeaker protection against thermal overload - involves heat sensitive switch in loudspeaker supply circuit
Inventor: THIELE KARL-HEINZ DIPL PHYS
IPC: H04R3/00
Filed: 1973-11-14
Abstract: The switch control means are heat sensitive and in thermal contact with the loudspeaker transducer system; the switch consists of the switching contact of a bimetal switch in thermal contact with the transducer system; the loudspeaker is supplied through at least a part of a frequency sensitive network, with the switch inserted between the amplifier output and the above network. When there is a build-up of heat in the coils of the loudspeakers, the bimetal switch is heated and it bends away from the loudspeaker coil, causing electrical contact to be broken. Contact is restored when the loudspeakers cool down again.
