Title: Process for the simultaneous production of ortho-, para- and 2,4-di-tert-butylphenol
Inventor: ALFS HELMUT
IPC: C07C37/14
Filed: 1984-11-30
Abstract: For the production of o-tert-butylphenol with simultaneous production of p-tert-butylphenol and 2,4-di-tert-butylphenol by alkylation of phenol with isobutene, an acidic ion exchanger based on sulphonated vinylpolymers which are cross-linked with divinylbenzene and which has been treated with > C3-olefins and has a C:S ratio of 9 to 30:1 and an exchange capacity of 3.0 to 1.5 meq/g, based on dried catalyst, is employed as the ion exchanger. This ion exchanger is obtained by long-term alkylation, 1000 to 6000 hours at a temperature of 80 to 150 DEG C, of phenol with olefins in the presence of a customary macroporous, acidic ion exchanger based on sulphonated vinylpolymers which are cross-linked with divinylbenzene. The alkylation is carried out at a temperature of 60 to 130 DEG C.

Abstract: Device for feeding cleaned air into the interior of a motor vehicle. It is known to suck air from the boot of a motor vehicle and to force it by means of a fan via a chemisorption filter into the passenger compartment. In order to introduce the cleaned and filtered air into the passenger compartment in such a manner that said air is collected by the intake side of an existing air conditioning system, it is proposed according to the invention to distribute a multiplicity of small, flexible, foot-load resistant tubes (4) made of plastic or metal, preferably 10-13 of them, uniformly below the rear seat of the motor vehicle and to lay them as far as from below the floor carpets from the rear seat forwards into the front foot space and to design them in the form of veins. The air feed from the rear compartment into the front compartment of the motor vehicle or vice versa can also consist of vein-like surface-covering mats or small tubes. <IMAGE>

Abstract: The invention relates to a component connection for electrical plug connectors which have a contact connection at one end and a connection region (for pressing into a through-plated hole in a female connector strip) at the other end, the connection region being bent in the pressing-in zone, and the side limbs which are thus formed running towards one another towards the free end of the connecting region and being bounded towards that end of the connecting region which is not free by a broadened region in the form of a collar, in which the bent region ends. The connecting region (1) is formed from two contact parts (2a, 2b), which are formed symmetrically with respect to the longitudinal axis (LA) of the same and have an approximately circular cross-section in the pressing-in region (E), the contact parts (2a, 2b) being designed in such a manner that the respectively opposite side limbs (3, 4) of the same form a resilient longitudinal gap (L) (elastic pressing-in tulip).

Filed: 1986-02-13
Abstract: Mineral acids are freed from heavy metals, especially copper, arsenic, antimony and lead by precipitating the metals in sulfide form. To this end, the mineral acid is reacted with hydrogen sulfide or an alkali metal sulfide solution under pressure and with thorough agitation, and formed solid matter is subsequently separated from the mineral acid under the pressure selected. The mineral acid may conveniently by admixed initially with a filter aid and then treated with hydrogen sulfide or the alkali metal sulfide solution.
Patent DE-3605604-A1 (DE)
Title: One-part clamp
Inventor: STAZOL MICHAEL
IPC: B60J10/80
Filed: 1986-02-21
Abstract: The invention relates to a one-part clamp made of sheet metal or plastic for positionally securing the edge of a lining carpet on a vehicle body part, with a holding part which can be fixed to the body part and on which there is arranged at least one holding clasp which together with the holding part defines a clamping gap for the edge of the lining carpet. Although a known clamp does secure the edge of a lining element it has an unattractive external appearance and must be covered by additional measures. According to the invention, it is envisaged, however, that in addition to the clamping gap there be provided a holding channel which is separate therefrom and in which a covering part, which conceals the clamp and that edge of the lining carpet which is fixed in the clamping gap, can be positionally secured in such a manner that the clamp permits both the fixing of the carpet edge and also the fixing of the covering part concealing the clamps and the carpet edge.

Title: Air suspension for vehicle with tandem axle
Inventor: FAHRNSCHON MATTHIAS DIPL ING
IPC: B60G17/052
Filed: 1986-08-23
Abstract: A device is proposed for the pneumatically assisted suspension of a vehicle with a plurality of rear axles, of which at least one rear axle serves as drive axle and at least one further rear axle as non-driven axle, for example a lifting axle. In order to improve the traction in difficult driving situations, the bellows (1) of the drive axle in each load condition are subjected to the maximum possible load not exceeding the admissible load. Should the vehicle load exceed the maximum admissible axle load of the drive axle, the bellows (1) of the drive axle assume their maximum admissible load and the bellows (2) of the lifting axle assume the excess proportion of the vehicle load. According to the invention the control valves (14, 16), which undertake the axle load distribution, are connected so that they have to be actuated only in the event of a variation of the vehicle loading. <IMAGE>

Patent DE-3633775-A1 (DE)
Title: Magnetic piston motor
Inventor: BAECKER KONRAD
IPC: F02B1/04
Filed: 1986-10-03
Abstract: The force which is required to operate this motor is achieved in that the magnetic piston is ejected from the magnet head (long force path). In order to make it possible to eject the piston from the head at all, the piston must either be pressed into the head using hydraulic force or the magnetic field of the head must be neutralised or destroyed by a powerful current surge. Both possibilities are thus unrealistic. In the case of the magnet head which I have developed, an iron conducting element having an excitation winding is located in the upper part. Resting on one side and on the opposite side with an air gap [sic]. The magnetic force thus remains fully effective downwards. In the event of a small amount of current flowing through the excitation winding, the magnetic field is immediately drawn into the upper circle (auxiliary circle) and the path for the piston becomes free. This switching can be repeated as desired and the full force of the magnet head is maintained. A transistor circuit, in the case of which only small currents flow via the distributor or interrupter, increases the life of the circuit.

Abstract: In the case of a three-phase invertor (5) which is composed of transistors (51-56) which are switched on and off on the basis of pulse-width-modulation control, the pulse widths of the control signals for the transistors (51-56) are determined on the basis of the amplitudes of two of the three phases of the current which is to be emitted by the invertor (5). The requirements on a processor (10) for producing the control signals can be reduced to a large extent and, in addition thereto, the wave form of the output current of the invertor (5) can be significantly improved. <IMAGE>
