Patent LV-13811-B (LV)
Title: Dc electric motor drive provided with hydrogen fuel cell
Inventor: PURVINS ARTURS
IPC: H01M8/00
Filed: 2008-10-09
Abstract: The invention refers to electrical engineering and can be applied in DC electrical drive systems. Its objective is to increase the efficiency of a DC electric motor drive. The offered DC electric motor drive with hydrogen fuel cell contains fuel cell 1, DC/DC power converter 4 and electrical motor 7. The distinctive properties of the proposed topology are defined by series connection of an induction coil 2 and the first double layer capacitor 3 wired parallel to the fuel cell 1 output, where the negative output of the first double layer capacitor 3 is joined to the negative output of the hydrogen fuel cell 1. Series connection of diode 5 and the second double layer capacitor 6 is joined in parallel to the DC electric motor 7, where the diode's 5 cathode is wired to one of the DC electric motor 7 brush, and the posistive output of the second double layer capacitor 6 - to other brush. The second double layer capacitor 6 is joined to the input of additional DC/DC power converter 8 and the first double layer capacitor 3 is joined to its output. Accumulated electrical energy in inductive elements of the DC electric motor 7 by disconnecting them from voltage sypply discharges through the diode 5 and is accumulated in the second double layer capacitor 6, and through the additional DC/DC power converter 8 energy is transfered to the first double layer capacitor 3. The current, when charging the first double layer capacitor 3 by the fuel cell 1, is limited by the induction coil 2.

Abstract: An omelette mix is prepared from a liquid egg product, which may be, for example, whole egg, egg white, egg yolk, a de-chloresterized or artificial mix, or any combination of two or more of the foregoing, by adjusting its pH, preferably with citric acid, then adding to it a hydrocolloid, comprising an alginate, adding a multivalent metal salt of only low solubility in water, e.g. calcium sulphate dihydrate, in order to facilitate any required cross-linking of the hydrocolloid molecular chains, mixing thoroughly to form a homogeneous material, forming this material into any desired shape and freezing or chilling it to produce a stable intermediate material that can readily be quickly heated to give an omelette in form ready for consumption. In general sodium chloride will be introduced into the mix, conveniently with the hydrocolloid, in order to enhance the flavour of the omelette. A sequestrant is desirably added to control the release of the multivalent metal salt and thus regulate the speed of the cross-linking reaction.

Title: Process for the conversion of carbonaceous feedstocks to particulate carbon and methanol
Inventor: STEINBERG MEYER
IPC: C10J3/54
Filed: 1990-10-17
Abstract: A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free carbon) from carbonaceous feedstocks (21). The basic process involves de-oxygenating one of the gas streams formed in a cyclic hydropyrolysis (10) methane pyrolysis (34) process in order to improve conversion of the initial carbonaceous feedstock. De-oxygenation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the pyrolysis gas streams (44), preferably the latter, to a methanol co-product. There are thus produced two products whose use is known per se, viz., a substantially pollutant-free particulate carbon black (53) and methanol (49). These products may be admixed in the form of a liquid slurry of carbon black in methanol.
