Abstract: 1,034,694. Charging and discharging batteries. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. May 14, 1965 [June 5, 1964], No. 23436/64. Heading H2H. In an airborne satellite having two or more batteries B1, B2 charged from solar cells CA, means are provided for changing the connections between the batteries and solar cells a number of times during each period of darkness and light so that during darkness, each battery alternates between standby and discharge and during daylight each battery alternates between full charge and trickle charge. The battery is charged during daylight by a timer operated switch ABC which is also controlled by a lowvoltage detector so that the battery having the lower voltage is maintained in the standby condition during darkness and trickle charge during the day. A radio signal over channel T1 may revert the sequence to normal. In the event of low output from another array of solar cells RA directly supplying the load, a comparator C1 reduces the load when the low voltage is during a period of daylight. An orbit counter OC restores the full load during darkness when a given number of orbits is sensed by the sun sensor SS. During launching, the batteries in parallel supply the load through switches S1, S2 which are returned to normal by another radio signal through channel T2 when the satellite is correctly orientated.

Title: Method of and system for supplementing control of air to fuel ratio for an internal combustion engine
IPC: F02D35/00
Filed: 1975-05-23
Abstract: 1481840 Air-fuel ratio control; spray carburetters GKN TRANSMISSIONS Ltd 23 May 1975 [28 May 1974] 23528/74 Addition to 1453312 Headings F1B aid F1H [ Also in Division G 1] The air-fuel ratio of an I.C. engine is subjected to supplementary control to maintain it below the stoichiometric ratio by a sensor which senses the oxygen content in the exhaust and sends a signal dependent thereon to a control device which maintains the oxygen content in the exhaust below a predetermined value. The sensor is located in the exhaust upstream of a catalyst unit, an electrical signal dependent upon the oxygen content being transmitted by the sensor to the control device, Fig. 2, which comprises a heating element 31 in contact with an axially expansible capsule 24 which may contain a silicone wax or fluid, the capsule displacing axially a bush 33 containing a pin 34 which co-operates with a helical slot 35 in a sleeve 36 fast with a bellows 22 which is thereby rotated, the bellows being connected to a frusto-conical cam eccentric to axis 23. The bellows is subject to the inlet manifold pressure and variation of its length due to variation in pressure, or bodily rotation due to expansion of the capsule causes the cam to operate metering means which determines the quantity of fuel injected into the engine in each cycle. A hole 42 in sleeve 36 registers with a hole 43 in a fixed sleeve 41 when the engine is cold to provide air to the inlet manifold for fast idle on starting from cold. In another embodiment, Fig. 5 (not shown), rotation of the bellows is effected by a bi-metallic strip which may be bonded to the heating element. In another embodiment the expansible capsule is replaced by an electromagnetic unit which may comprise a field structure, Fig. 4 (not shown), with a frusto-conical aperture in which moves a frusto-conical armature. In addition the frusto-conical cam may be moved axially rather than causing rotation in response to the electrical signal, Fig. 8 (not shown). Alternatively, the electromagnetic unit may comprise a winding, Fig. 6 (not shown), which attracts an armature secured to sleeve 36 which may be supported in its end remote from the bellows in a bearing, Fig. 7 (not shown), rotation of the armature being effected by engagement with a helical ramp. In the embodiment shown in Fig. 9, fuel is supplied by a carburetter having a needle 60 entering a jet tube 61 and displaced by a piston 62 in response to variations in the subatmospheric pressure occurring within a throat 63. The jet tube is displaceable vertically by an axially expansible capsule 24 provided with a heating unit responsive to the signal from the exhaust oxygen sensor.

Abstract: 251.511. Bloxam, A. G., (Chemische Fabrik Griesheim-Elektron). Sept. 23, 1925. 2: 3: 5-Trichlorbenzaldehyde is obtained from 2: 3: 5-trichlortoluene in the usual manner. 2 : 3: 4: 5-Tetrachlorbenzaldehyde is obtained by passing a mixture of chlorine and air through a. solution of 4-chlor-aceto-o-toluidine, saponifying the 3 : 4 : 5-trichlor-aceto-o-toluidine thus obtained, exchanging the NH2 group for chlorine by the Sandmeyer reaction, chlorinating the resulting 2:3:4:5-tetrachlortoluene in the side chain, and saponifying the product. It can also be obtained from a mixture with the 2 : 3 : 5 : 6- tetrachlorbenzaldehyde by making use of the different solubilities of their bisulphite compounds. Mixtures of the two tetrachlorbenzaldehydes are obtained by treating mixtures of 3: 4: 5- and 3:5:6-trichlor-acidyl-o-toluidines as described above; these latter mixtures are obtained when chlorine and air are passed through a solution of an acidyl-o-toluidine,or through a solution of a mixture of the acidyl compounds of 4- and 6- chlor-o-toluidine, which results when o-nitrotoluene is chlorinated, reduced, and acidylated. Tri-arylmethane dyes are obtained by condensing 2:3: 5-trichlor- or 2 : 3 : 4 : 5-tetrachlorbenzaldehyde with two molecules of an N-mono- or di-alkyl derivative of an arylamine, or a mixture of such derivatives, and subsequently oxidizing the leuco-base with lead peroxide. The products dye mordanted cotton, silk, and artificial silk pure blue or bluish-green shades, and may also be used for the manufacture of lakes and pigments. In examples, 2 : 3 : 5-trichlorbenzaldehyde is condensed with mono-ethyl-o-toluidine, and 2 : 3 : 4 : 5-tetrachlorbenzaldehyde is condensed with diethylaniline. Dimethylaniline and other N-alkyl-arylamines can be used for the condensation.
