Abstract: The invention relates to an apparatus for determining by optical means the contact angle (wetting angle) at the solid-liquid interface, allowing the hydrofobicity of some materials to be studied and estimated and the surface pressure to be determined in research activities, in industry, and in particular in textiles, plastics, dyestuffs industries etc., as well as in agriculture. The apparatus comprises an optical measuring unit (A) mounted in front of a sample-holding device (B), on a base plate (C). The optical unit (A) comprises a horizontal axis objective (4), a 90 reflecting prism (5) and an eyepiece (6) integral with a cross reticle (7) ensuring a magnification of 50-100 times of the image of a liquid drop (2) on a sample (1) placed on a mobile table (18) of the sample-holding device (B), having three mobility degrees and a mobile mirror (30) for the adequate illumination of the liquid drop (2). The size of the contact angle (alpha) is determined either directly, by measuring on an instrument dial (14) in correspondance with an indicating pointer (13), or indirectly, by trigonometric calculation, after the previous measurment of the diameter "D" and height "H" of the liquid drop (2).

Title: Rivet
Inventor: CIOARA GH GHEORGHE ROMEO
IPC: F16B19/05
Filed: 2006-03-16
Abstract: The invention relates to a rivet meant to mount the half-cages of some types of bearings. According to the invention, the rivet consists of a rod wherein two zones (a and b) are provided, a cylindrical zone and a zone of a non-circular profile, respectively, which are inscribed in a circle (d) of a larger diameter than the diameter of another circle (e) of a cross-section of the cylindrical zone (a), placed in the vicinity of a head (c), said later zone (b) having three or four flat surfaces (f) or 3...5 concave profiles (g), while the two circles (d and e) are not totally coaxial.
Patent RO-123130-B1 (RO)
Title: Process for preparing the immunosorbent trenbolone-3-carboxymethyloxime-ovalbumin-carboxymethyl-cellulose
Inventor: DOROBANŢU IOAN
IPC: G01N33/531
Filed: 2007-12-19
Abstract: The invention relates to a process for preparing the immunosorbent Trebolone-3-Carboxymethyloxime-Ovalbumin-Carboxymethyl-Cellulose (Tren-3-CMO-OVA-CM-Cellulose) used in affinity chromatography for the purification of anti-trebolone specific antibodies. According to the invention, the process consists in dissolving CM-cellulose, N-hydroxy-succinimide and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide in dimethylformamide, followed by ovalbumin admixture in carbonate buffer, centrifugation, removal of supernatant, washing the resulting precipitate, CM-Cellulose-Ovalbumin, with distilled water, and renewed suspension thereof in sodium carbonate buffer, followed by the coupling reaction of trebolone-3-CMO with the conjugate CM-Cellulose-Ovalbumin, to obtain the desired immunosorbent, namely Trebolone-3-CMO-Ovalbumin-CM-Cellulose, which is washed with a solution of ethyl alcohol in distilled water and stored at a temperature of 4°C.
