Title: A system of geophysical exploration
IPC: G01V7/06
Filed: 1962-01-24
Abstract: 955,191. Geophysical exploration. JERSEY PRODUCTION RESEARCH CO. Jan.24, 1962 [April 19, 1961], No. 2732/62. Drawings to Specification. Heading G1W. A method of geophysical exploration relies on the fact that gravitational attraction of the sun and moon causes periodic movements of the land masses which are somewhat similar to movements of the waters of the earth and thus are referred to as earth tides. Sensitive gravity meters may be used to measure the earth tides at a plurality of spaced survey locations, corrections being applied, if necessary, for differences caused by the differing latitudes and longitudes of the survey locations. All the measurements may be effected simultaneously or alternatively simultaneous measurements may be made at one or more survey locations and at a base station, the measurements then being taken with different survey locations and the same base station so that the final results may all be reduced to a corresponding basis. The peak amplitudes of the earth tide waves may be plotted on a map at points corresponding to the survey locations. Alternatively measurements may be made by means of sensitive tilt detectors, arrows being plotted on a map of a length and direction corresponding to the magnitude and direction of the tilt at the various survey locations. In further methods the rate of change of the earth tide wave at a selected time is measured or other earth deformation characteristics or characteristics of the wave form are selected. Alternatively the time that the peak of the earth tide passes through a base station and through spaced survey locations are determined and compared with the calculated time that the earth tide should pass from the base station to the survey stations.

Filed: 1966-01-21
Abstract: 1,070,619. Tank wagons; bottom discharge wagons. PICKANDS MATHER & CO. Jan. 21, 1966, No. 2829/66. Heading B7L. [Also in Division B8] A locomotive 11 drawing cars 10 along rails 36 carries contact 27 which in turn engages stationary contacts p<SP>11</SP>, 1<SP>11</SP>, 2<SP>11</SP>, 3<SP>11</SP>, 4<SP>11</SP>, 5<SP>11</SP>, 6<SP>11</SP>, 7<SP>11</SP>, w<SP>11</SP> to cause plough P to descend to the position shown, and spouts from each of outlets 1-7 of hopper 8 to descend and also wheels W. Plough P then engages and opens the hatch of each car 10, and a contact on each car engages the contacts P8, 1<SP>1</SP>-7<SP>1</SP>, and w<SP>1</SP> in turn to operate valves so that material from hopper 8 descends through the shoots up to a predetermined amount into each car. Each car thus receives material from a plurality of the shoots in turn till it sinks on springs into a non-engaging position. Each shoot valve is self-closing. Each hatch then engages wheels W to be closed thereby. The end wagon 12 of the train operates by means of contact 29, contacts P<SP>1</SP>, 1<SP>1</SP>-7<SP>1</SP>, and w<SP>1</SP> to raise plough P, the spouts and wheels W so that the apparatus is left in its original position after the train now loaded has passed hopper 8. Hatch 45, Fig. 8 (not shown). Car (10) is provided with hatch (45) pivoted at (46) and provided with bracket (50) the roller (59) of which engages lowered plough (P) to cause hatch (45) to open. Likewise, the hatch is' adapted to engage wheels (W) which causes it to close. Additionally, cover (45) which is spring held at (54) is provided with a cam (61) to effect the opening of the shoots of the hopper when the hatch is swung to the vertical position. Outlet 1 (Fig. 11, not shown). Each hopper outlet is provided with a sliding valve (65) having an aperture (65a) and moved horizontally by solenoid (66). It carries spout (14) which is bendable as shown. The bending is effected by means of motor (M) and bars (21) pivoted at (20). Thus as car 10 passes outlet 1 the cam (61) of the car closes switch (71) to cause solenoid (66) to open valve (65). Likewise, contact 27 on locomotive 11 closes contact (for example) 1<SP>1</SP> to start motor (M) which through gears (17) and (19) rotate shaft (20) to cause bars (21) to bend spout (40) to the vertical position shown. Also contact 29 on end wagon 12 closes contact 1<SP>11</SP> to bend the spout to the horizontal position. Car 10, Fig. 5 (not shown). The car is provided with pivoted discharge doors 43 which are operated to close or open by engagement of wheels 41, 42 with fixed cams. Cover 45 is also shown operated by the engagement of plough P with roller 59.

Title: Improvements relating to gas-fired water heaters
IPC: F24H9/20
Filed: 1942-03-05
Abstract: 553,648. Gas fired water heaters. EWART, J. H., and EWART & SON, Ltd. March 5, 1942, No. 2889. [Class 135] [Also in Group XIII] A gas-fired water heater of the kind in which the gas valve is opened by the pressure caused by a restriction in the water supply conduit has the restriction variable by a manual operating member which also controls the inflow of water so that by manipulation of this member the heater can be adjusted to deliver cold, hot or boiling water. The gas valve 16 is opened against the action of a spring 17 by water pressure acting below a diaphragm 19 which also actuates a valve 34 to maintain a constant water pressure in an annular chamber 22. The valve 34 is arranged in a chamber 23 supplied with water through a conduit 25 fitted with an adjustable throttle 26. The control valve 28 is mounted on a screwed spindle 29 fitted with a handle 32 and has one face fitted with a washer adapted to close the inlet to the chamber 23 and an opposed face adapted to throttle variably the outlet from the chamber 23 to a chamber 39. From the chamber 39 a pipe 6 in contact with the outside of a flue 2 leads to a boiler 1 fitted with heat conducting fins. A secondary water supply leads from the chamber 22 leads to the boiler by way of a thermally controlled ball valve 8. In the position of the control valve shown in the Figure the supply of water is shut off. Moving this valve towards the right permits cold water to be discharged from the spout 42. Further movement to the right throttles the connection between the chambers 23, 39 so producing a pressure sufficient to open the gas valve and water passes to the boiler by ways of chambers 23, 22 and 39. Further movement closes the connection between the chambers 23, 29. This is the " boiling " position and water passes to the boiler by way of chamber 22 and narrow passage 22<SP>1</SP>. In the event of the water boiling steam passing to the atmosphere by way of vent 15 acts on a thermo-sensitive element 9 to open the valve 8 and establish a supplementary water supply from the constant pressure chamber 22 through a pipe 7 so preventing excessive escape of steam. The passage connecting the chamber 22 to the chamber below the diaphragm is fitted with a throttle device to permit a slow flow in the valve opening direction and a rapid flow in the reverse direction. A gas governor 43 is fitted in the gas supply conduit. Specification 549,223, [Group XIII], is referred to.

Title: Improvements in carrier frequency signalling systems
IPC: H03C1/58
Filed: 1933-01-31
Abstract: 417,251. Modulating systems; wireless receiving systems. HALSEY, R. J., Hooksway, Woodmansterne Road, Carshalton, Surrey. Jan. 31, 1933, No. 2968. [Class 40 (v).] A modulating or de-modulating circuit comprises a plurality of impedances including one or more rectifiers arranged to form a balanced bridge, the carrier and /or the signal voltage being applied across one diagonal, and the modulated or demodulated output minus one or both of the applied voltages being taken from the other. As shown in Fig. 4, the signal voltage 1 is applied through a transformer, the divided secondaries of which are respectively in series with pairs of rectifiers 3, 4 and the carrier voltage 2 is applied in the common branch. The rectifiers have their likepoles connected as shown. The output is taken through condensers 5 and transformer 6 connected across one pair of rectifiers 4. In Fig. 5b the input voltages are both applied in the common branch of the two circuits, and a resistance 5 replaces one pair of rectifiers 3, 4, the output being tapped off at an intermediate point of the resistance. In another arrangement the input voltages are both applied in push-pull fashion. Fig. 1 shows the carrier applied through a transformer T3 to a tapped resistance P. The end taps are connected through rectifiers W to the opposite ends of a transformer coil T2, and the centre tap is connected to the centre of the coil T2 through a coupling T1 at which the signal voltage is applied. The output is taken from the secondary of the transformer T2. The circuit may be used in wireless reception, the carrier source being either of the same frequency as the incoming signal or of different frequency. The rectifiers 3, 4 may be of the copper oxide type and are similar, so that the sum of the forward resistance of one and the backward resistance of the other is constant. The Provisional Specification describes simpler circuits in which the two input voltages are applied in series to a single rectifier, with the output impedance arranged in series or in shunt ; or two series connected rectifiers may be employed with the output impedance connected across one of them. In a further arrangement, the signal wave and the carrier are applied to the grid circuit of a valve in series with a condenser-shunted resistance, and the plate circuit includes a transformer with a rectifier connected across its secondary coil.

Title: Process for the production of sultams
IPC: C07D279/02
Filed: 1954-02-02
Abstract: A sultam of general formula <FORM:0752227/IV(a)/1> where R1 is a saturated aliphatic hydrocarbon radical containing from 3 to 6 carbon atoms, and R2 is a hydrogen atom or an alkyl group containing not more than 3 carbon atoms is produced by a method comprising subjecting a mineral acid salt of the corresponding aminoalkane sulphonyl chloride to cyclo-dehydrochlorination by heating or by treatment with a basic reagent.  The salts of amino-alkane sulphonyl chlorides used as the starting material may be obtained by sulpho chlorinating mineral acid salts of aliphatic amines of the general formula HX.NHR1R2.  When the cyclodehydrochlorination is carried out by heating the mineral acid salt dissolved or suspended in an organic solvent preferably to a temperature in the range 50-120 DEG  C.  If the formation of the sultams is effected by the use of a basic reagent the temperature at which the reaction is carried out is preferably below 60 DEG  C. and suitable basic reagents are inorganic bases such as ammonia, hydroxides of alkali metals or alkaline earth metals and organic bases such as aliphatic amines, pyridine, quinoline and alkali metal alkoxides of aliphatic alcohols.  In the examples: (a) 1-amino-butane sulphonyl chloride hydrochloride is heated in various solvents to give butane sultam; on hydrolysis of the product with hydrochloric acid 4-aminobutane sulphonic acid is obtained; (b) 1-aminopentane sulphonyl chloride hydrochloride is dissolved in methanol and treated with ammonia to give a pentane-sultam; (c) the sulphochlorination product obtained by treating n-butylamine hydrochloride with sulphur dioxide and chlorine is mixed with n-butylamine and subsequently treated with hydrochloric acid to give butane sultam; (d) the sulphochlorination product obtained by treating n-pentylamine hydrochloride with sulphur dioxide and chlorine is treated with pyridene and subsequently with hydrochloric acid to give pentane sultam; (e) the sulpho-chlorination product obtained by treating propylamine hydrochloride with chlorine and sulphur dioxide is treated with caustic soda solution and subsequently with hydrochloric acid to give propane sultam; (f) 1-amino-butane sulphonyl chloride is treated with sodium ethoxide to give butane sultam, and (g) the sulphochlorinated sulphuric acid salt of butylamine is treated with baryta lye to give butane sultam.
