Patent DE-3805473-A1 (DE)
Title: Process and equipment for hardening wire rings
Inventor: MOEBIUS HANS-EBERHARD DIPL ING
IPC: C21D9/54
Filed: 1988-02-22
Abstract: The invention relates to a process and to equipment for the heat treatment of wire which has been wound up into rings, the rings being austenitised, being hardened with excitation of resonant vibrations and subsequently being tempered. The invention essentially comprises carrying out, by means of a single manipulator with C-hooks located in the centre of a plurality of hood ovens, the discharging of the ovens, the spreading of the ring out of the arc of the C-hook to the end of the hook, the excitation of the ring to resonant vibrations, the dipping of the ring into the hardening bath, the rotation of the ring about its ring axis, the lifting and lowering of the ring within the bath, the removal from the bath and the deposition onto a floor conveyor means. The advantages are that, in this way, small quantities of wire rings can be hardened and tempered economically, independently of large, high-throughput rolling lines or even large continuous ovens. A further advantage is that the individual hood ovens can be adjusted with respect to temperature and time to the different conditions for the austenitisation of different grades and also for tempering to different temperatures. There is the further advantage that the unit is adaptable in its capacity, since the central manipulator can be connected to only one hood oven but can also be surrounded by two, three or even four ovens.

Title: Armour plate
Inventor: DIETSCHE HORST DIPL ING
IPC: F41H5/04
Filed: 1988-06-15
Abstract: In an armour plate for strongboxes, safes, burglar-proof wall claddings or the like, a perforated sheet is arranged between an outward-facing cover sheet made of special steel proof against oxyacetylene cutting and a baseplate. The cavities limited by these three components are filled alternately with two different layered structures: the first layered structure I comprises a first layer adjacent to the cover sheet and consisting of high-alloy, stainless or carbide-containing material (called the "wearing layer" in brief), a layer located above it and consisting of hard-metal particles and a second wearing layer which is welded over the layer of hard-metal particles. The second layered structure II likewise comprises a first wearing layer which is applied to the cover sheet, but over which a small ceramic plate then lies. This is covered, in turn, by a second wearing layer. The armour plate thus constructed successfully withstands even the attack of highly specialised grinding tools.

Title: Device and method for increasing the resolution in the analogue/digital conversion of signals with a DC component
Inventor: BECKER THOMAS DR ING
IPC: H03M1/12
Filed: 1988-10-28
Abstract: In this method, the DC component of the aggregate signal is estimated by a signal processor. This estimated DC component is converted to an analogue value and subtracted from the aggregate signal. The remaining aggregate signal can therefore be amplified as much as is allowed by the modulation limits of the analogue/digital converter. This increases the resolution.
Patent DE-3840668-A1 (DE)
Inventor: HAUFFE DIETER
IPC: C23C22/73
Filed: 1988-12-02
Abstract: During phosphatizing of metal surfaces comprising at least partly iron or steel by dipping or flooding by means of phosphatizing solutions containing film-forming cations and nitrate or equivalent accelerators, the iron content is limited through precipitation of iron phosphate by withdrawing discontinuously a portion of the phosphatizing solution from the bath tank (1) and contacting it, in a separate aeration unit (3), with oxygen or an oxygen-containing gas, and feeding the resultant solution, freed from iron phosphate sludge, back into the bath tank (1). According to the invention, the portion of phosphatizing solution is introduced from below into an aeration unit (3), which is fitted with a self-aspirating aerating stirrer (4) which narrows at least in the lower region, and is aerated. When aeration is complete, the iron phosphate formed is allowed to settle, and the phosphatizing solution, with a depleted iron(II) content, is sucked upward and fed back into the bath tank (1). 
<??>In a particularly advantageous procedure, the iron phosphate sludge deposited principally in the narrowed region of the aeration unit (3) is stirred up in water with the aid of a stirrer (8) projecting into the narrowing region, but this is not carried out until several batches have undergone precipitation treatment.
