Title: Monocrystalline products mfr. from e.g. metals with forced cooling - useful in making turbine fins and permanent magnets
IPC: C30B11/14
Filed: 1975-09-01
Abstract: An appts. for making monocrystallie metal products incorporates a ceramic mould and a cooling unit. The mould has a housing in its base for a crystal primer. The cooling unit has a flat plat which is mounted below the mould and can be moved vertically. It has an axial hole through which a tube passes. The interior of the tube is divided into two sections by a partition. The upper section fits over the primer housing. The lower section can be supplied with a cooling liq. The upper part of the tube is made of a metal such as tungsten or molybdenum, with a thermal conductivity giving the max. temp. gradient along the primer. The lower part is made of stainless steel, the junction being in the cooling unit, where the temp. is low. Device is used for mfr. of mono-crystalline prodts. from metals and alloys, having a predetermined crystal structure, e.g. in fins for turbines and in permanent magnets. The service life of monocrystalline turbine fins is 4 times greater at max. operating temp. and 6 to 8 times greater at moderate temps., than that of polycrystalline fins. The strength of monocrystalline permanent magnets is 2.5-3 times that if polycrystalline ones.

Title: Poly-(para)-phenylene terephthalamide (co)polymers prodn. - by reacting (para)-phenylene diamine and terephthalic acid dichloroanhydride in soln. with a tert. amine
IPC: C08G69/32
Filed: 1976-07-15
Abstract: Poly-p-phenylene terephthalamide (co) polymers are made by (1) dissolving p-phenylenediamine (I) or a mixt. or (I) and a diphenyl diamine in a solvent consisting of (a) linear or a mixt. of (I) and a diphenyl diamine in a solvent consisting of (a) linear or cyclic N-alkyl substd. acid amides abd (b) alkali (ne earth) metal salts which are soluble in the amide, and used at 1-3 moles per mole dissolved diamine; (2) Introducing into the soln. at 0-20 degrees C an equimolar amt. (on diamines) of terephthalic acid dichloroanhydride (II) or a mixt. of (I I) and a diphenyl series dichloroanhydride; (3) introducing 2-6 moles (per mole diamine) or a tert. amine (III); (4) stirring the reaction mixt. for 3-70 mins; and (5) recovering the desired prod. from the reaction mixt. Suitable tert. amines (III) are alpha-picoline, beta-picoline, dimethylbenzlamine, dimethylaniline, quinoline, pyridine, triethylamine or N-methylmorpholine. The presence of the tert. amine increases the rate of polycondensation of the reactants and allows the prod. of higher mol. wt. prods. The higher rate of polymerisation also reduces the purity requirements of the solvent compared with prior art processes, and it is possible to obtain high mol. wt. polymers using solvents contg. 0.07 % moisture. The poly-p-phenyleneterephthalamide (co)polymers are polyamides having high thermal stability, mechanical strength and solvent resistance. They are useful e.g. in the prodn. of fibres used for making tyre cords and as a reinforcement for plastics materials.

Arrangement results in a great improvement in productivity compared with the manual cutting of gall bladders. Injuries are eliminated and better hygienic conditions are created. The recovery of gall fluid mis more complete and is of higher quality.

Title: Selective vehicle identification system - uses multiplier and logic circuit for spectral analysis of IR from exhaust gases
IPC: G01S3/781
Filed: 1979-09-20
Abstract: The remote detection system uses the exhaust gases emitted by a vehicle IC engine to produce a selective identification. The exhaust gases provide an infrared absorption spectrum which presents an instant contrast to the spectrum of the ambient air. A spectral filter provides an electric signal which is amplified and applied to one input of a comparator. The second input receives a reference signal representing the ambient air. A circuit for correcting the reference signal includes a delay acting on the comparator output in parallel with a low-pass filter which eliminates the detector pulse signal. A variable multiplier signal introduces a contrast correction function, and an adder forms the algebraic sum of the delayed voltage and the multiplied voltage to form the reference voltage signal.

Title: Switched vertical deflection circuit
IPC: H04N/
Filed: 1984-07-09
Abstract: The field deflection circuit includes a deflection winding (27) coupled to a voltage source. An energy storage element (26) coupled to the winding provides current in the winding and a source of line deflection rate energy incorporates a switch (33). A predetermined amount of the line deflection rate energy is applied to the energy storage element during a first portion of each line deflection interval and a predetermined amount of energy is removed from the storage element during a second portion of each interval by a circuit (21). A unidirectional current control element (40) completes a current path from the winding (27) to a source of reference potential (ground) via the switch during a portion of a field deflection interval in response to operation of the switch. Thus a switched vertical deflection circuit derives vertical deflection current from horizontal deflection energy.
