Patent BG-48388-A1 (BG)
Title: Method for processing of rubber coagulate
Inventor: NATOV MILCHO A
IPC: C08C3/00
Filed: 1989-05-09
Abstract: This method is an application for the manufacture of directly extruded rubber blends. It is used to obtain transportable bulk rubber coagulates with an extended shelf life. Minimum shelf life, depending on the type of rubber or powdering agent used, it is 60 days. The method involves treating crumbs of dried rubber coagulate with thermoplastic powders at temperatures not exceeding 120 degrees C, followed by cooling down to 50 degrees C (air-induced, over a running belt conveyor) and packaging in polyethylene or masked paper bags. Polyethylene, polypropylene, polystyrene, polyacrylonitrile or polyvinylchloride are used as thermoplastic powders.

Title: Camera for diffuse welding in vacuum or inert gas
Inventor: KALEV LJUBOMIR TS
IPC: B23K20/14
Filed: 1989-09-25
Abstract: The chamber's construction ensures that the variances emerging from parallelity or axial displacement between the welded pieces and the elements transmitting the power of pressing, are recompensed. This guarantees uniform allocation of superficial pressure upon the welded surfaces. The chamber includes a corpus (1) with water cooling, at the upper part of which is affixed a mobile lid (4) with a fastened statically spherical heel (6), to which through a body (8) is attached a top changeable support (7). The corpus (1) is supplied at the front with an aperture for charging and monitoring. The lower part of the corpus (1) hosts a hermetic power inlet (16), connected to an inductor (18) and a rod (12) with a sylphonic congestor (13). The rod (12) is connected with a hydraulic cylinder (14) and is fitted to the bottom part of the corpus (1), coaxially to the spherical heel (6). To the rod (12) is fastened a bottom support (11), on which the welded pieces (9 and 10) are centred. The body (8) is connected with the spherical heel (6) through a self-accustoming conical-spherical joint.

Title: Reservoir de carburant en plastique avec mamelon de tuyau
Inventor: SADR CHANGIZE
IPC: B29C65/06
Filed: 2000-01-04
Abstract: Cette invention se rapporte à un système de réservoir de carburant à utiliser dans l'automobile et dans des applications similaires et contribuant à limiter les fuites de vapeur risquant de se produire aux endroits où les mamelons de tuyaux ou de conduits sont fixés à un réservoir de carburant en plastique multicouche. La couche extérieure du réservoir de carburant est fabriquée à partir d'une polyoléfine modifiée avec fonction anhydride ou acrylate. Le raccord du tuyau souple est choisi dans un matériau ayant une contrainte de fluage supérieure à celle du matériau de la couche extérieure et un module d'élasticité en traction supérieur à celui du matériau de la couche extérieure. On obtient ainsi un raccord de tuyau auquel un conduit flexible peut être adapté par sertissage de façon à former un joint d'étanchéité qui ne se détériore pas en raison de défauts de fluage, tout en permettant le soudage relativement aisé du raccord du tuyau au réservoir.

IPC: H04L1/06
Filed: 1990-05-01
Abstract: ABSTRACT OF THE DISCLOSURE In a space diversity receiver, multiple signal paths are connected respectively to antennas for multipath reception.  Each signal path includes a digital demodulator coupled to the antenna and an impulse response detector, or autocorrelator connected to the demodulator for deriving a channel impulse response of each one of the multiple paths.  A maximum response detector is con-nected to each impulse response detector for detecting equilizable delay components which give a maximum response value and unequali-zable delay components.  A power ratio of the unequalizable delay components to the equalizable delay components is derived for each signal path and a minimum value of the power ratios is determined and one of the signal paths in which the minimum value is detected is selected.  The output signal of the demodulator of the selected signal path is applied to one input of an equalizer, or a maximum likelihood sequence estimator, and the equilizable delay compo-nents of the selected signal path are applied to the other input of the equalizer.
