Title: Esters of fatty-aromatic acids with aminoalcohols and process for obtaining the same
IPC: C07D295/14
Filed: 1933-02-24
Abstract: Amino-alcohols of the formula <FORM:0396318/IV/1> in which R represents an alkyl group and R<1> an alkyl group or hydrogen, are esterified with fatty-aromatic acids, giving products which possess antispasmodic action.  Examples are given of the esterification of 2 : 2-dimethyl-3 - diethylaminopropanol with phenylacetyl chloride and acetyltropyl chloride and of 2 : 2-dimethyl-3-dimethylaminopropanol with cinnamoyl chloride.  Amino-alcohols of the above formula may be prepared by reduction with sodium amalgam in acetic acid solution of the amino-aldehydes whose preparation is described in Specification 348,382.  Acetyltropyl chloride is obtained by heating tropic acid with acetyl chloride and then with thionyl chloride.

Title: Improvements in or relating to a system for electrical prospecting
IPC: G01V3/04
Filed: 1948-02-26
Abstract: 633,322. Prospecting for minerals. NORDEL CORPORATION. Feb. 26, 1948, Nos. 5758 and 5759. Convention dates, Feb. 25, 1943 and April 24, 1943. [Class 37] In an electrical system for geophysical exploration a series of alternate positive and negative pulses is applied to a pair of earth electrodes and means are provided for measuring the potential between the same or other earth electrodes during the intervals between the pulses. Earth electrodes 27, 28, Fig. 2, are connected over a reversing switch 35 to a further switch 15 which brings a D.C. source 10 and measuring voltmeter 20 alternately into circuit. The switches are continuously driven with the switch 15 operated at double the speed of the switch 35. The circuit also includes a battery 41 and potentiometer for balancing the natural earth potential. In a further embodiment a D.C. source is connected via a reversing switch 95, Fig. 4, to an earth electrode 99 and to the mid-point of a network of resistances 101, 102, 103, 104 bridging a pair of earth electrodes. Further earth electrodes 117, 123 are connected to a galvanometer 110 over a reversing switch 115 which is driven at the same speed as the switch 95 but is so timed that its contacts are closed when those of the switch 95 are open, and vice versa. A battery 121 and potentiometer are provided for balancing the natural earth potential. In operation, the resistances 101, 102 are adjusted for zero potential between the electrodes 117, 123, as indicated by the galvanometer 110 and the ratio of the currents in the branches 101, 102 is then measured by means of the potentiometer 104, which is adjusted for zero deflection of the galvanometer 107. In a simplified arrangement (Fig. 3, not shown), the D.C. source is connected over a reversing switch to a first pair of earth electrodes and a galvanometer to a second pair as in Fig. 4, the potential between the second electrodes being measured by means of an opposing potential derived from a battery and potentiometer in series with the galvanometer and which is adjusted to obtain a null indication.

The cross-sectional area of the duct between the valves 3. 5 may be reduced by means of a set screw 14. The valve 5 may be loaded by a spring 7 and provided with a relief valve 9 the tension of which may be increased by depressing a piston 11 under the control of an accelerator pedal 12 or a centrifugal governor. Alternatively it may be in the form of a needle valve, or in the form of a rotatable slide valve 17, Fig. 4 having teeth 23 engaged by a rack 37 for arbitrary regulation. The valve 17 may be made to slide by connecting it to a governor which operates over the whole or a part only of the range of speed of the engine, or only when the speed exceeds or falls short of a certain range. This latter kind may include strong and weak springs 25 and 26, the valve 17 being moved in the direction 28 or 29 when the speed falls below or exceeds the desired range, the valve chamber being connected by passage 27 to the delivery pipe of the fuel feed pump. The valve 17 may be governed by the suction pressure by means of a suction pipe 27<SP>1</SP>, or it may be independent of the suction pressure.
