Title: Improvements in or relating to methods of electrical frequency submultiplication
IPC: H03B19/12
Filed: 1936-11-27
Abstract: 486,017. Valve generating circuits. BAIRD TELEVISION, Ltd., and TINGLEY, G. R. Nov. 27, 1936, No. 32533. [Class 40 (v)] A valve having three grids is used as a frequency divider by coupling the outer grid and plate so as to oscillate at the desired output frequency and coupling the two inner grids so as to oscillate at a frequency intermediate between the desired and the controlling or input frequency. The two inner grids are connected to two windings of transformer 2, Fig. 1 (Prov.), so as to oscillate at a frequency which is a submultiple of the controlling frequency, this being applied to a third winding on transformer 2. The frequency of oscillation is adjusted by means of a variable resistance 3 as described in Specification 456,666. The outer grid and plate are coupled through a transformer 4 to oscillate at the desired frequency, the frequency adjustment being made by a resistance 5. Synchronization between the oscillatory circuits is effected through resistances 7, 8 and condenser 6. Output is taken from the anode through condenser 10 and potentiometer 11, 12. In Fig. 1 (Comp.) controlling pulses are passed through a diode 13 to the control grid, the intermediate and desired frequencies being synchronized through condenser. 6 and a diode 14. Other methods of synchronizing the desired and intermediate oscillations are described; in a modification of Fig. 1 (Prov.) the low frequency outer grid is directly connected to the junction of the resistances 7, 8 ; in Fig. 2 (Prov.) (not shown) use is made of an additional winding on each of the transformers 2, 4 these two windings being connected; in Fig. 2 (Comp.) (not shown), a third transformer is employed the primary winding being connected in the low frequency oscillatory circuit and the secondary winding being connected through a condenser to the controlling grid of the intermediate frequency oscillatory circuit.

Title: Aliphatically Substituted Uretidiones
IPC: C08G18/79

Abstract: 1,153,815. Aliphatically substituted uretidiones. FARBENFABRIKEN BAYER A.G. 14 July, 1967 [21 July, 1966], No. 32544/67. Heading C2C. The invention comprises aliphatically substituted 1,3-diazacyclo-2,4-butanediones (uretidiones) of the general formula where R represents an aliphatic hydrocarbon radical which may be substituted or unsubstituted. Preferably R is a linear or branched alkyl radical of 1-6 C atoms or an alkenyl radical of 3-6 C atoms. R may be substituted with NCO, haoogens, nitrile, alkoxy, carbalkoxy or dialkylamino groups as well as aromatic radicals such as phenyl or naphthyl. The compounds are obtained by the dimerization of the corresponding isocyanates (R.NCO) at 0-180‹ C. in an inert organic solvent, if desired, and preferably in the presence of a catalyst, the reaction being terminated when from 5-50% of the reactants have reacted, some of the corresponding isocyanurate derivative generally being formed as by-products. Suitable catalysts are tertiary phosphines containing at least one aliphatic group, boron trifluoride or complexes thereof, a hydrogen halide or diazabicyclo-(2.2.2)-octane. The phenyl ester of N-ethyl carbamic acid is prepared by reacting diethyl uretidione with phenol and diethylmethyl biuret is prepared by reacting diethyl uretidione with methylamine.

Title: Mechanical oscillating drive for spiral conveyor

Abstract: 848,120. Vibratory mechanisms. RUZICKA, J. Oct. 18, 1957 [Oct. 19, 1956], No. 32609/57. Class 80 (4). In order to impart to a spiral conveyer 6 a rotary oscillation having an adjustable vertical component for upward conveying, two parallel horizontal shafts 4 rotating at the same speed in opposite directions carry two pairs of eccentric weights m mounted on discs 1, 2, 5, 5<SP>1</SP> on the shaft ends. The discs 1, 2 may be formed as interengaging gears. Each pair of adjacent discs is angularly adjusted to produce a linear oscillation inclined to the vertical, the vertical components of the two linear oscillations lying in the same direction and so combining to produce a vertical oscillation of the conveyer, while the horizontal components are in opposite directions and so combine to produce a torsional oscillation of the conveyer. The disc 5<SP>1</SP> is symmetrical with the disc 1 and the disc 5 is symmetrical with the disc 2. The radial positions or masses of the weights m may be individually varied so long as the products of mass and radius are equal. The speed of the shafts 4 may be varied by means of a belt drive to vary the frequency of oscillation. The amplitude of oscillation is adjusted by altering the weights m. It is stated that the four discs shown may be adjusted to produce only a torsional oscillation, and further eccentricallyloaded discs be provided to produce the vertical oscillation.
