Filed: 1976-12-17
Abstract: 1537118 Sawtooth deflection circuits INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 17 Dec 1976 [26 Feb 1976] 52736/76 Heading H3T In a circuit to provide sawtooth current in a deflection coil 11 connected in series with a capacitor 12 the conduction of a switch 4 starts flyback by causing transformer winding 13 and capacitor 15 to resonate, subsequently diode 8 clamps the voltage to provide the trace and returns energy to the source. Commutation of the switch 4 is caused during the trace by an oscillation involving coil 9, capacitor 10, deflection coil 11, and the effects of capacitor 15 reflected through transformer 13. In operation the diode 8 is conductive throughout the trace period. Diode 14 and capacitor 16 provide a D.C. output voltage, while parasitic oscillations in coil 9 are damped by capacitor 7 and resistor 6. To minimize losses the effective inductance of coil 9 should be less than that of the deflection coil while that of inductor 3 should be larger. It is stated that variation of the ratio of the transformer 13 and consequently the values of coil 9 and capacitor 10 can be used to ensure correct conduction in diode 8 to suit the available supply voltage.

Abstract: 1371898 Fluid-pressure servomotor systems NORMALAIR-GARRETT (HOLDINGS) Ltd 4 Nov 1971 [20 Nov 1970] 55347/70 Heading G3P [Also in Division F2] A pressure regulating valve 34 is controlled by a piston 36 subjected to a datum pressure in chamber 40 and to the downstream pressure communicated through apertures 38 with chamber 37. The datum pressure is derived from the valve inlet pressure via passage 25 and pressure reducing valve 17. Departure from the selected downstream pressure moves the piston/valve assembly 33, thereby altering the datum pressure in chamber 40 and producing a pressure difference across diaphragm 15. Consequently, the valve 17 is adjusted in a sense towards restoring the datum and downstream pressures. Orifice 24 suitably restricts flow to and from chamber 13 so that the rate of response of the assembly 33 varies with the rate of change of downstream pressure. A pressure relief valve 18 is also present. The casing has an annular shield 53 for deflecting dirt carried by the controlled flow away from the sliding clearances at valve 34. A light spring (not shown) moves the assembly 33 to the closed position when the valve is inoperative. Diaphragms 15, 16 may be replaced by pistons.

The hydrocarbon-substituted γ- butyrolactone acetic acid starting material is obtained by the acid hydrolysis of an alkenyl succinic anhydride prepared by a known method by reaction between an olefin and maleic anhydride (or a halosuccinic anhydride or succinate ester). The lactone starting materials may be prepared from different types of alkenyl anhydrides, viz. Type I anhydrides, wherein at least one of the carbon atoms attached to the double bond is in the main chain of the alkenyl group and which yield γ-hydrocarbon γ-butyrolactone acetic acids, and Type II anhydrides wherein carbon atoms attached to the double bond are outside the main chain of the alkenyl group and which yield a predominant amount of #-hydrocarbon γ-butyrolactone acetic acid. Reaction of lactone acids derived from Type I anhydrides with an alkali metal salt or base, or with an amine, followed by further reaction with an amine, produce an alkali metal or amine salt of a 3-amido-5-hydroxy carboxylate, which, on further heating, yields the corresponding amide. Reaction of lactone acetic acids derived from Type II anhydrides with an alkali metal salt or amine produces the corresponding lactone acetate salt, or upon heating the amine salt, the amide. The amine employed may be a mono- or poly-amine which may be ethoxylated before or after reaction with the lactone acid; the use of a polyamine may lead to polymeric products, e.g. with alternating polyamine/amide/lactam groups. The products may be used as hard water soaps or additives for industrial organic fluids.
