Title: Signal generating process for use in engine control
IPC: G01F15/02
Filed: 1973-07-24
Abstract: 1409583 Automatic electric control of fuel supply to I C engines FORD MOTOR CO Ltd 24 July 1973 [24 Aug 1972] 35165/73 Heading G3N The amount of fuel supplied to an I.C. engine is controlled by a signal dependent upon the rate of air supplied to the engine cylinders through the intake duct, the signal being provided by partially obstructing the air-flow in the duct to provide vortices and modulating an electrical signal at a rate proportional to the rate at which the vortices are produced. As described, the air-flow is partially obstructed by a cylindrical rod, the construction of the flow senses being described with reference to Figs. 1-4 (not shown). As shown in Fig.5, an oscillator 62 supplies a carrier signal to an ultrasonic transmitter 52, the ultrasonic signal being modulated at the rate at which the vortices are produced. A receiver 54 picks up the ultrasonic signal and provides an equivalent electrical signal to an amplifier and detector 70. The output of unit 70 is applied to a filter and amplifier 72 whose output is applied to a bi-stable circuit 74. The bi-stable output triggers a one-shot multi-vibrator 78 which provides constant duration pulses at the rate of vortex production. An integrator 82 provides a D.C. signal having an amplitude proportional to the rate of vortex production. For controlling the supply of fuel to the engine, the D.C. signal is compensated in a unit 90, Fig.7 (not shown), by signals related to the air-pressure and temperature in the inlet duct. The compensator 90 thus produces a signal related to the air mass flow, this signal being applied to a pulse width modulator 98 which is triggered in synchronism with engine rotation to energize a fuel injector 38. Alternatively, an electronic carburetter may be used to control fuel supply.

Title: Improvements relating to the preparation of alkali metal salts of terephthalic acid
IPC: C01B31/08
Filed: 1963-09-09
Abstract: Active carbon used to purify an aqueous solution containing a dialkali metal salt of terephthalic acid produced by the Henkel rearrangement is regenerated by washing with water after separation. The water wash may be preceded by an aqueous alkali wash, preferably 2-20% by wt. conc.  Suitable alkalis are caustic potash, caustic soda, sodium and potassium carbonates and bicarbonates and ammonia. Washing is preferably done at 60 DEG  F. boiling. The alkali washing and water washing can be repeated, preferably alternately.  Powder carbon is preferably treated in stirred suspension. Granular carbon is preferably treated as a fixed or moving bed, circulating the washing liquid through it. The regenerated carbon may be recycled. Example 1 illustrates water washing; Examples 2, 3 and 4 caustic soda and water; and Example 5 repeated caustic soda and water washings.ALSO:An alkali metal salt of terephthalic acid prepared by the Henkel rearrangement is decolorized by contact with active carbon.  The carbon is regenerated by water washing, possibly preceded by washing with aqueous alkali, and is reused to decolorize more alkali metal salt.  The alkali wash may be done with an alkali metal hydroxide carbonate or bicarbonate or ammonia at an alkali conc. of up to 20% by weight. Alkali and water washing may be repeated.  In Example 1, dipotassium phthalate containing 3.5 mol. per cent of cadmium phthalate is heated at 440 DEG  C. in a CO2 atmosphere under a pressure of 10 kg./cm.2 for 1 hour.  The resulting suspension is filtered, and to 5.0 litres of the filtrate containing 205 gms. of dipotassium terephthalate per litre is added 15 gms. of powdered active carbon containing 50% water.  The mixture is stirred at 60 DEG  for 1 hour.  The regenerated carbon is reacted with a further 5 litres of filtrate as before.  In example 3, the filtered dipotassium terephthalate solution is passed through a granular active carbon bed. In Example 4 and 5 dipotassium terephthalate is firstly crystallized from the filtered solution, dissolved in water, and passed through a granular active carbon bed.

Abstract: 815,457. Diversity receivers. TELEFUNKEN G.m.b.H. Nov. 15, 1957 [Nov. 17, 1956], No. 35649/57. Class 40 (5). In a diversity radio receiving system in which the changeover from one to another of the input channels is effected by changes in received signal strength, each input channel is divided and applied to a pair of diodes, all the outputs of the pairs of diodes being connected to a common circuit which feeds the receiver, one pair only of the diodes being biased to conduct at one time when the signal in that input circuit reaches a level determined by the output of the receiver, and when the level falls, the outputs are sampled in turn until the level is restored. In the embodiment described, as applied to a two-antenna space diversity system, the antennae 1, 2, Fig. 1, are connected to R.F. transformers 3, 4, having centre-tapped secondaries, a pair of diodes being respectively connected in each of the secondary circuits, which are thereafter connected to a common output transformer 9, and known receiver 10. The A.G.C. circuit of the latter triggers a bi-stable circuit 16 which, when the signal level falls, produces through a resistor 11 a bias voltage to render conducting the pairs of diodes sequentially until an input circuit carries a stronger signal, the other pair remaining non-conducting. The self-capacities of the diodes are neutralized by trimming capacitors 12, 13, 14, 15. In a further embodiment, Fig. 3, applied to a multiantenna system, a ring counter 17 selects and renders conductive a pair of diodes while the signal output from circuit 9 exceeds a given value, and thereafter samples the output of each antenna sequentially, until a signal develops exceeding the given value.
