Title: Reducing water retention of sand for glass mfr. - by treating wet sand with surfactant during transport to glass-works
Inventor: KINDT REMY
IPC: C03C1/02
Filed: 1976-08-19
Abstract: The water retention capacity of sand is uniformly reduced by adding 5% of a surfactant per tonne of sand.

Title: Rotary to reciprocating transmission mechanism - has concave bearing surface with two conical portions inclined to shaft axis
Inventor: MORIARTY MAURICE J
IPC: F16H39/00
Filed: 1976-09-30
Abstract: The transmission mechanism converts rotary into reciprocating movement or vice versa, having a shaft rotating in a stationary housing and with an annular bearing surface at one end whose axis is inclined to that of the shaft. Components on the shaft end hold a bearing against the surface, the bearing being enclosed by a yoke ring with diametrically opposite bearing trunnions, by which it rocks in the housing on an axis perpendicular to that of the shaft. The bearing fits in the ring by a further pair of trunnions at right angles to the first pair. A second shaft extends from the yoke ring coaxially with its trunnions, its free end acting as the power output or input. The bearing is automatically held against the annular V-section concave bearing inner surface, which is integral with the first shaft and formed by two conical portions on the same axis.

Title: Control method for physical characteristics of fluid medium - is by transmission of ultrasonic vibrations through pipe wall at angle given by specified relationship
Inventor: KRYLOVA ELEONORA DMITRIEVNA
IPC: G01N29/02
Filed: 1976-10-19
Abstract: Vibrations are transmitted to the medium under control through a sound conducting medium and through a pipe wall at an angle Alpha acute or obtuse, to the pipe exterior, the angle being determined by the relationship: Alpha = arcsin C ( 2.C). where: Co is the velocity of propagation of ultrasonic vibrations in the sound conducting medium, and C is the velocity of propagation of transverse ultrasonic vibrations in the material of the pipe wall. The frequency f of the ultrasonic vibrations being transmitted is selected according to another specified relationship. Parameters of the ultrasonic vibrations, passed through the medium under control, are then measured and their value is used to determine the value of a parameter being controlled.

Title: Penicillanic and cephalosporanic acids prepn. - by acylating the amino derivs. using an oxazolidone ester as active acylating species
Inventor: MESEGUER JOSE DIAGO
IPC: C07D501/06
Filed: 1977-01-18
Abstract: Acylation of 6-amino penicillanic acid (6-APA), 7-amino cephalosporanic acid (7-ACA) and 7-aminodesacetoxy cephalosporanic acid (7-ADCA) and their derivs, comprises (i) reacting (a) a 3-substd. 2-oxazolidone of formula (I) with (b) the salt of a carboxylic acid with a tert. organic base, in methylene chloride at -15 to +20 degrees C foe 15-120 min. to give a mixt. contg. as active acylating species, an acid halide, N-acyl-2-oxazolidone and 2-acyloxy-delta2-oxazolidone (A); and (ii) reacting this mixt. with 6-APA, 7-ACA or 7-ADCA of formula (II) in an inert solvent to give a penicillin or cephalosporin (where R1 and R2 are H or lower alkyl; X is halogen, R is lower alkyl, Ph, halogen or dimethylamino; n is 1 or 2; (H)2 is O or 2, H atoms or 1Me; (H)1 is 0 or 1 H atoms; R4 is H, alkali metal, trimethylsilyl or phthalidyl; and R3 is Me, azidomethyl, acyloxymethyl, thiomethyl, 5-methyl thiadiazolyl-2-thiomethyl, cyanomethyl or methoxymethyl). Acylation by (A) requires mild conditions (0-20 degrees C) so optical activity in the acids is retained, and less energy is required for the reaction. All cpds, resulting from the reaction of (I) are water-soluble and therefore easily removed (the P cpds. are easily decomposed, and 2-oxazolidinone itself is harmless), except if (I) is e.g. chloro-N-oxazolidine triphenylphosphorane, in which case as triphenylphosphine oxide is extremely soluble in methylene chloride, while the antibiotic (as Na salt) is soluble in water, the two phases can easily be sepd. The antibiotics can be obtd. in the required purity.

Title: Metering and mixing system for explosive mixing - using ammonium nitrate and carbon with pneumatic metering system
Inventor: RIEGELMAYER PETER DIPL ING DR
IPC: B01F5/04
Filed: 1977-03-01
Abstract: Process for continuous mixing of powdered or granular solid e.g. NH4NO3 with a liquid esp. diesel oil in a specified ratio involves feeding the solids into a holding hopper and then metering them out of this into a mixing device. The liquid is fed into the mixing chamber with an excess volume and pressure available and this is then regulated to a specified solids flow. Beneath a solids storage vessel there is located a rotary seal and a pneumatically actuated mixing chamber which is connected to a liquid pump. There is a common drive for both seal and pump. The pump delivers excess of that required for the mix and the fine control is then provided by a pressure regulator. Used for mixing NH4NO3 and diesel oil to provide explosive for use in quarries and prepared on site. The mixer describes gives reliable proportioning at all times and thus provides a reliable explosive mix of ANC (ammonium nitrate carbon explosive).
