Patent BG-49796-A1 (BG)
Title: Electro- magnetic connector
Inventor: MLADENOV LJUBOMIR P
IPC: H01H5/10
Filed: 1990-01-22
Abstract: The contactor can be used in AC control and automation devices and circuits. It has a simplified design, small dimensions and improved matching between static characteristics. The contactor contains a spring system, which includes two springs - a return spring and an engagement spring, mounted so as to allow their attenuation by the trigger mechanism. The summed up characteristics of the connector, engagement and return springs can be obtained after adjustment, which is similar to that of the electro-mechanical characteristics of the contactor winding.

Title: Method for creating genotype plants tolerant to low temperatures
Inventor: ATANASOVA BISTRA TS
IPC: A01H3/04
Filed: 1993-03-08
Abstract: The method is applied in the selection of cold-resistant plant genotypes, tomatoes, in particular. It ensures simultaneous germination of the tomato plants, regardless of the soil conditions. The plant tolerance to low temperatures in the germination phase is raised several times, while the selection is conducted in an expressly shown phenotypical sign. Following the method, the donor is a line, homozygotic in one to two recessive mutant genes, related to the pigmentation of the tomato plant. After the standard hybridisation with another, non-tolerant line, a selection of the disintegrating generations at a "hypocotyls" phase is carried out, following the mutant marker sign.

Inventor: TAN KHAY G J
IPC: C25C1/20
Filed: 1990-05-17
Abstract: An efficient hydrometallurgical refining method is disclosed for the production of high purity silver. The method comprises:   casting an anode of raw silver; subjecting the cast anode to an electrorefining stage wherein the raw silver is directly electrorefined in a suitable  electrolyte  solution;  leaching  the  anodic residue  with  an  approporiate  lixiviant  to  dissolve impurities and precipitate silver in the form of a silver compound  that  is  suitable  for  conditioning  the electrolyte;  treating  the  leach  liquor  to  recover dissolved silver and recycling recovered silver to the leaching or anode casting stage; and treating the anolyte in  a  conditioning  stage  with  an  appropriate  silver compound prior to recycle to the electrorefining stage as catholyte.   The process is fast and simple to operate since the sequencing of steps has been rationalized and the reagent requirements and harmful emissions are low. The life of the electrolyte extends over many electrode cycles and valuable byproducts are also recovered.   In the preferred embodiment,  raw silver anodes with major arsenic  and  antimony  impurities  are  electrorefined directly;  e.g.,  in  a  silver  nitrate  medium  using  a diaphragm cell.   The major impurities form a porous, thick  and  adherent  layer  which  is  spalled  off periodically.  Pure silver is deposited at the cathode as a dense powder at a high current efficiency.  The anolyte is  pumped  to  an  external  conditioning  circuit  where Ag2SO4  and  lime  are  added  to  maintain  a  stable electrolyte composition.  The treated electrolyte is then recycled to the cathode compartment.   Silver sulphate (Ag2SO4)  is  produced by  leaching the anodic residues and/or other suitable materials in a separate step.

Title: Air deflector mounting bracket
Inventor: SPEARS DAN E
IPC: B62D35/00
Filed: 1990-07-05
Abstract: Substantial improvements in trucking equipment during the past few years, including steel belted tires and improved engines which developed less friction have substantially reduced the resistance to travel and the cost per mile of operating tractor and trailer equipment. These and other improvements which decreased the cost of attaining and maintaining higher speeds did nothing to reduce the cost of applying the brakes to tractor and trailer units. It was therefore desirable in the interests of safety and economy of operation to find some way of reducing the cost of applying braking forces (to the units) at less cost.      Applicant's invention has the two-fold advantage of reducing the trucking costs at road speeds by providing movable air deflecting fairings to streamline the flow of air outwardly beyond the trailer unit. When braking forces are needed applicant immediately opens up the fairings, and opens side doors to scoop and channel more airflow than the normal width of the assembly to impinge directly on the front of the substantially flat front surface of the trailer. This is particularly effective on long down hill runs where the cost of prolonged braking is expensive and is very destructive to the maintaining of the vehicles braking equipment in top operating condition.
