Abstract: 1,052,551. Metal containers for preserving food and beverages. A. R. D'ANDREA. April 6, 1964, No. 14050/64. Heading A2D. [Also in Division B8] In metal containers for preserving foods or beverages, and having an inner non- metallic, e.g. lacquer, coating, part of a wall of the container is formed of a metal more negative in the galvanic series than the remainder of the container, and the coating on this part is permeable to the contents. The body of a can may be made of tin plate and an end of aluminium, the lacquer on the aluminium being permeable. Solution of tin or iron ions in the contents, which would otherwise occur if the lacquer or tin-coating were damaged, is suppressed by the protective electrical potential of the aluminium, so that the taste and appearance of the contents are not objectionably altered and the shelf life increased. The tin plate may be coated with either a permeable or impermeable lacquer. The contents being always in contact with the aluminium will form an aluminium salt which in the presence of an excess of metal becomes a basic salt with poor permeability and slows down the electrolytic action, but the small amount of conduction remaining maintains the anodic potential which suppresses the solution of tin and iron ions.

Abstract: 1,227,883. 883. Fluid logic and switching circuits; regulating I. C. engines. NATIONAL RESEARCH DEVELOPMENT CORP. Aug. 1, 1969 [Aug. 1, 1968], No.36677/68. Headings F1B and F1P. [Also in Division G3]. A fuel supply system for an I. C. engine 10 Fig. 1 comprises means for generating a primary signal in the form of a series of time-spaced air pressure pulses in a line 19 and of frequency dependant on engine speed, e.g. an air pump 14, nozzle 15 and a slotted disc 18 driven by the engine, means 20 for modulating the pulses e.g. duration thereof as a function of a parameter representative of the fuel requirements for a given air intake and liquid fuel injection means 13, 24 responsive to the modulated pulses to determine the rate of fuel supply. The pulse modulating means may comprise a variable delay unit 29 Fig. 2 connected by a restricted line 21 branching from the air intake manifold 11 upstream of a throttle valve 12, a fixed delay unit 30 in parallel with unit 29, and a monostable amplifier 33 having control ports 37, 38 respectively connected to the output of units 30, 29 a constant air supply line 34, a vent output 40 and a working output line 23 leading to main inlet 64 Fig.4  of the liquid fuel injection means 24, which latter is an air to fuel transducer. In operation fuel from a pump 25 is admitted to an inlet 63 and in the absence of an air pulse at 64 the liquid fuel passes along a passage 65 and an outlet 67 to a return tank (not shown). An air pulse at 64 deflect the light fuel along a passage 68 to an outlet 71 connected by a line 26 to injector 13 whilst the air pulse is deflected by arcuate surfaces 69, 70 along passage 65. Passages 72, 73 are provided for matching fluidic load at the entrances to 65,68 irrespective of the loading at outlets 67, 71. The basic pulse signal in line 19 at high and low engine speeds is shown in the left and right hand portions of curve A Fig. 5 and the variably and fixed delayed pulses at high manifold pressures are shown in curves B, C. The control signal in line 23 at low and high engine speeds and high manifold pressure is shown by curve D from which it is seen that whilst the pulse frequency and magnitude is equal to those of the basic signal in line 19 the duration i. e. the width of each pulse in line 23 is reduced. Curve E shows the variality delayed signal in line 31 at low manifold pressure, whilst curve F shows the control signal in line 23 at low manifold pressure. Fig. 3, 7 (not shown) show alternative pulse width modulation circuits whilst Fig. 9 (not shown) shows a circuit for modulating the amplitude of the primary pulses proportional to the absolute pressure in the manifold.

Abstract: 1288988 Compensating for lead impedances LICENTIA PATENT-VERWALTUNGS GmbH 13 Nov 1970 [15 Nov 1969] 54234/70 Heading G1U In order to obtain, independently of lead impedances, a measure of the potential across a sensing element 3, Fig.1, as a result of passing a constant current from a generator 9 through it, rather than using two additional voltage sensing leads, one extra lead 4 and one extra identical constant current generator, connected as shown, are used. The potential across terminals 6 and 7 of the constant current generators, which may be amplifier 14 and indicated 17 in any appropriate manner, is then a measure of the required potential. This is so because the leads 4 and 5 will both carry the same current in a direction towards the sensing element, and therefore the voltage drops across them are of equal magnitude and when seen from terminals 6 and 7 are in series opposition. The saving of one lead to the sensing element is particularly worthwhile when the leads are long and when a plurality of sensing elements are sequentially monitored from a remote point (as in Fig. 2, not shown).

When the device is used for fuel flow control, the compressor delivery and inlet pressures P4 and P1, are used, a variable pressure Ps in the inlet duct 26 of the primary nozzle 16 being obtained from P4 and P1 by means of a potentiometer comprising a fixed restrictor 27 and a variable restrictor 28 controlled by a hand lever 31. The primary nozzle 16 discharges at 18 to the pressure P1. A secondary nozzle 21 has its inlet connected to the duct 26 via a restrictor 23, and has an output passage 24 terminating in a control nozzle 34 opening tangentially into a vortex amplifier 35. A sonic jet issuing from the nozzle 16 impacts in the region of a receiver nozzle 19 against a subsonic jet issuing from the nozzle 21. If as a result of moving the lever 31, or as a resulting change in the compressionratioP4/P1, the ratio Ps/P1 is raised in the region of the critical value (1À89) at which the flow through the nozzle 16 becomes sonic, the resultant movement of the jet impact position causes the output pressure Po in the passage 24, and therefore also the ratio Po/P1, to vary abruptly by a large amount. The vortex amplifier 35 acts as a comparator of the pressure Po relative to a reference pressure, in a radial passage 36, obtained from the pressures P4, P1 by a potentiometer 37, 38. The resultant variation in the pressure in a power output pipe 42 relative to the pressure, obtained from the pressures P4, P1 by a potentiometer 46, 47, in another power output pipe 41 is used to operate fuel flow control means.
