Inventor: VASILIEV EVGENIJ A
IPC: C21C1/10
Filed: 1977-09-09
Abstract: Spheroidal graphite cast iron is produced by melting an Fe charge having a C content >2 wt % and adding solid cast iron which contains a spheroidal graphite-forming element such as Mg and/or Ce in 4-10 times the amt. necessary to form spheroidal graphite in the final cast iron product.

Title: Caster wheel for chair that can be braked when not under load - has rocker arm made of springy polyoxymethylene
Inventor: SCHROEDER DIETER
IPC: B60B33/02
Filed: 1977-10-19
Abstract: Caster wheel for a (push)chair has a load-bearing component for >=1 wheel, at which there is >=1 brake shoe bearing on the wheel when a load is removed from the chair. The axle of the wheel fits into the bore of a rocker arm moving against elastic force w.r.t. the load- bearing component.

Title: Oxygenation of stretches of water at predetermined depths - by ice blocks with hollow cavities containing liquefied gas
Inventor: BALDUS WOLFGANG DR
IPC: B01J4/00
Filed: 1977-12-01
Abstract: Oxygen or air enriched with oxygen is enclosed in blocks of ice, and these are put into water which it is desired to enrich in oxygen. The oxygen or oxygen enriched air is enclosed in the ice blocks in the liquid condition.

Title: Spectroscopic measurement of paramagnetic components in solid objects - using microwave technique in magnetic field with amplified rectified signal fed to recorder
Inventor: KARTHE WOLFGANG DIPL PHYS DR
IPC: G01R33/60
Filed: 1978-09-23
Abstract: Spectrometer measures the spatial distribution of paramagnetic centres in solid bodies using a microwave unit. The sample is placed inside a magnetic coil with means of producing changes in the polarising field with time esp. gradients. The signal generated from the microwave unit is feed to an amplifier, then rectified and recorded. The magnetic gradients are created by gradient coils. These have cylindrical, rectangular or other sorts of coiled surfaces. They are arranged relative to the sample such that the intensity, phase and direction of the polarising magnetic field can be freely selected. The gradients are produced by impulses generated from a key, an impulse generator and an amplifier. Simultaneous control of the signal monitoring system is provided. Arrangement allows measurement of diffusion processes in solids, of mass transfer processes or changes caused by disease in living bodies, or to evaluate the effectiveness of nucleation in crystal culture. Allows the determination of spatial assays, avoiding the simultaneous distruction of the sample.

IPC: C03B5/26
Filed: 1978-11-13
Abstract: This is an addn. to 2752467, which described a melting furnace for minerals, using heating electrodes immersed in the melt. The novelty in this addn. is that the bottom outlet of the furnace is formed by a cylinder located above a ring disc, both being made of a refractory which conducts electricity at high temps. so they function as heater elements and are fed by a transformer, which is also connected to at least one counter-electrode in the melt.
