Title: Improvements in or relating to tunable oscillatory systems consisting of capacitatively coupled circuits
IPC: H03H7/01
Filed: 1932-04-11
Abstract: 391,598. Impedance networks. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. April 11, 1932, No. 10368. Convention date, April 25, 1931. [Class 40 (iii).] The coupling between two oscillatory circuits L1C1, L2C2 is capacitive and is compounded of two couplings of which one increases while the other decreases with frequency. The dimensions are such that the total coupling either is constant or varies in a predetermined manner with frequency. If in two equal circuits L1C1, L2C2 medium-sized condensers C1, C2, Fig. 1, are varied to vary the frequency, while C3 is small and constant, the coupling coefficient C3/#(C1 C2) or c#<2> increases with frequency ; while if C4, Fig. 2, is large and constant, the coupling coefficient is #(C1 C2)/C4 or a# <2>, and decreases as the frequency is increased. According to the invention, the two systems are combined in various ways. A mediumsized fixed condenser may be connected between sand t, Fig. 1, to give a coupling coefficient of the form (c #<2> - b), or between q and r, Fig. 2, to give (a #<-2> - b), Figs. 6 and 7 (not shown). By interchange of certain elements a coefficient of the form (c #<2> - a #<-2>) can be obtained Two medium condensers may be inserted between s and t and between u and v to give (a #<-2> - b + c #<2>), Fig. 8 (not shown). The arrangement shown in Fig. 3, where C6 is large and C5 small, gives a constant coupling coefficient. A symmetrical form of this arrangement, Fig. 4 (not shown), employs six condensers. The arrangement shown in Fig. 5 employs three small condensers C3 and three large condensers C4, and gives a coupling coefficient of the form (a #<-2>+ b + c #<2>).

Title: Production of n,n'-diacetyl methylene diamine
Inventor: ELLIS JAMES
IPC: C07C233/90
Filed: 1963-03-18
Abstract: N,N1 - Diacetyl - methylene diamine is prepared by reacting formaldehyde with acetamide in the presence of an acid-reacting condensation catalyst and an organic liquid which is inert under the reaction conditions and which has a boiling-point in the range of 100 DEG  to 200 DEG  C.; the reaction mixture also contains (a) an excess of acetamide over that required for reaction with the formaldehyde, and (b) a mother liquor obtained after separating the crystalline product of a previous reaction.  The formaldehyde is preferably used in the form of paraformaldehyde. The water formed during the reaction is preferably removed as an azeotrope with the organic liquid and the organic liquid, after it has been dried, is then used to wash the crude crystals before being returned to the reactor.  A by-product of the reaction which remains in the mother liquor is triacetyl dimethylene triamine which is believed to react with acetamide, in the process of the invention, to form N,N1-diacetyl-methylene diamine.  The washed crystals of the product of the process of the invention may be reacted with ketene to give N,N,N1N1-tetraacetyl-methylene diamine. Examples are given.

Abstract: A crude pyrethrum extract containing 20-30% weight of materials extracted from the pyrethrum flowers in a higher boiling point hydrocarbon solvent (b.p. 150 DEG  to 280 DEG  C.) such as kerosene is purified by admixing the extract with kerosene in amount such that the mixture contains 10-15% weight of pyrethrins and with 0.5 to 7% weight of a quaternary ammonium halide, agitating the p  mixture, cooling to -10 to -30 DEG C. for 1 to 30 hours and separating the insolubles at this temperature.  It is preferred to heat the mixture prior to agitating and cooling, and in the examples the mixture is heated to 70 DEG  C. and then stirred for 1 or 2 hours. The clarified pyrethrin solution may then be treated with carbon to remove colour and is used as such or after further dilution with kerosene.  It is preferred that the quaternary ammonium compound has the general formula <FORM:0881841/VI/1> wherein R and R1 are C 1 to 5 alkyl, R11 is an aliphatic hydrocarbon radical containing 12 to 18 carbon atoms, R111 is C 1 to 5 alkyl or an aliphatic hydrocarbon radical containing from 12 to 18 carbon atoms and X is chlorine or bromine.  Preferred are coco-trimethylammonium chloride and dicocodimethyl ammonium chloride, the "coco" radical being obtained by the hydrogenation of coconut oil and is a substantially saturated alkyl radical containing 12 carbon atoms when pure and C10-14 alkyl when impure.
