The steel is heated to a temperature above that at which the vanadium carbonitrides and niobium carbonitrides and the titanium carbides are completely transformed into the solid-solution state, rolled at less than 950 DEG C at a total thickness reduction of more than 40 %, quenched by simultaneous cooling immediately after the rolling step from a temperature above (A3-50) DEG C and tempered at a temperature below the value Ac1. The mass flow density (W) of the cooling water for the quenching is determined according to the following equation (I) or (II) corresponding to the plate thickness (t)     (I) for plates of a thickness of more than 40 mm:   W = 0.7 to 1.5 m<3>/min.m<2> (II) for plates of a thickness of more than 25 mm and less than 40 mm:   W = 0.7 to (8.5-0.1t)/3 m<3>/min.m<2>.   <IMAGE>

Patent DE-3423203-A1 (DE)
Title: Control system
Inventor: BUSS JUERGEN
IPC: H03G3/00
Filed: 1984-06-22
Abstract: For various reasons, it is desirable to control the level or level pattern of a useful audible signal (e.g. loudness-related control, compression, expansion). If these actions are carried out at the transmitting end, this may lead, for example, to loss of quality, or it is not even possible for reasons of compatibility. With the aid of a control system which operates with additional information which is obtained prior to transmission and transmitted in parallel with the useful signal, the control operations can be carried out continuously in the broadcast receiving device. The type of control and thus the purpose is determined solely by the transmitted additional information. With this control system it would then be possible, for example, to transmit additional information for compression of the useful signal. Broadcast listeners with the corresponding receiving module can activate the latter in the event of increased ambient noise (e.g. in a car), whereby the user no longer needs to carry out constant manual volume re-adjustment. As an extension of the control system, the broadcast listener can also be provided with the facility to manipulate the received additional information prior to its processing and thus adapt the control system according to his personal requirements.
Patent DE-3427326-A1 (DE)
Title: Mixing head for producing a preferably chemically reactive mixture of at least two plastics components
Inventor: TAUBENMANN PETER
IPC: B29B7/76
Filed: 1984-07-25
Abstract: The mixing head comprises essentially a housing (1) with a central bore, a section of the bore being designed as a mixing chamber (2). Inlet openings (3) and (4) for the individual plastics components open out into the mixing chamber, in which a discharge piston (5) of uniform cross-section can be moved to and fro. Furthermore, the mixing chamber has an outlet opening (10) for the mixture of plastics components. The discharge piston is actuated by feeding a pressure medium to one or the other piston side of a working piston (19) which is firmly connected to the discharge piston. In order to improve the metering accuracy of the plastics components, there is incorporated into the pressure medium circuit of the working piston a disc piston (23) whose actuating face (23a) facing away from the working piston can be pressurised with a pressure medium until it reaches a shot stand-by position C of the discharge piston. In order to move the discharge piston into the mixing position B, the actuating face (23a) is relieved. <IMAGE>

IPC: G11B5/845
Filed: 1985-06-29
Abstract: The invention relates to a process for producing a binder-containing magnetic recording carrier which, for a defined system, is compatible with respect to the memory characteristics. The process is characterised in that uniaxial pigments of high remanence are used and that the liquid magnetic dispersion is aligned in a magnetic alignment system with a perpendicular, alternating, monotonously decreasing field structure in such a way that a recording carrier having a relatively low BR/BS value is obtained, which at the same time has very good surface property. To enhance the signal level, a second layer, whose magnetic pigment can have a uniaxial or multiaxial anisotropy, can be coated on top of this recording carrier.

Title: Typewriter or office machine of similar design for selective printing on single sheets or margin-perforated continuous form paper
Inventor: FRERICHS KLAUS-DIETER DIPL ING
IPC: B41J13/10
Filed: 1985-11-25
Abstract: In modern typewriters or office machines, selective printing on single sheets or margin-perforated continuous form paper is essential. For this purpose, the appropriate transporting devices are arranged so that they can selectively be inserted or removed or even pivoted out of the machines. Converting the machines for the one or other mode of operation has to date still been very complicated. The invention is based on the object of providing a typewriter or office machine of similar design for selective printing on single sheets or margin-perforated continuous form paper, which allows simple switching over to the one or other mode of operation. This object is achieved in that the roller platen (16) and a platen (22) which feeds the continuous form paper (6) in the printing region are arranged on a carrier (17), by means of whose pivoting into one end position the roller platen (16) for single-sheet operation and, into the other end position, the platen (22) for continuous form paper operation can selectively be moved into the operating position. By simple pivoting of the carrier (17) by hand into the one or other end position, the respective mode of operation is determined without any additional manipulations being required. <IMAGE>

Title: Process for the production of bicomponent fibres, fibres produced therefrom, and their use
Inventor: HENSEN FRIEDHELM DR ING
IPC: D04H3/007
Filed: 1985-12-17
Abstract: The invention relates to a process for the production of a bicomponent fibre of low linear density from polypropylene mixed with from 5 to 20 % by weight of polyethylene, which can be produced inexpensively and is therefore particularly suitable for use in the hygiene sector. The polymers are melted as a hopper mixture, spun and stretched at below the natural stretching ratio. In the fibre, the polyethylene components accumulate to an increased extent at the fibre edge due to their relatively low melting range, while the polypropylene forms the fibre core. This enables favourable melt bonding of the bicomponent fibres at low calendar roll temperatures during production of nonwovens.
