The heating tube and/or surrounding tube 21 may contain nickel which acts as a catalyst for the reactions taking place therein. Additional fuel may be added to the returning gases at 19, a reaction taking place in the heated channel 21 to produce the desired protective atmosphere. Similar apparatus may be used for producing a protective atmosphere for other uses, e.g. for filling the tanks of an oil tanker when the cargo is discharged to prevent risk of fire. In this case the heating tube is placed either inside or outside a heating chamber which receives a fluid to be heated, e.g. the water which has already been used for cooling in the heat exchanger. Fuel gas is added to the dewatered exhaust gases as before to react by contact with the hot surface of the heating tube as before to produce the desired protective atmosphere.

Abstract: 1299270 Spark erosion A P PEDRICK 23 Oct 1970 Heading B3V An apparatus for making very small (e.g. 5À5 Î 10<SP>-5</SP> cm. diameter) holes in a plate, e.g. to produce a "light screen" as described in Specification 1,206,260, employs a spark gap between electrodes 16, 17 set up in an evacuated space 22 subjected to a magnetic field produced by like, and therefore mutually repelling, magnetic poles. The Specification contains an account of a theory of magnetism in which it is asserted that the apparent repulsive forces existing between like magnetic poles are not true forces of magnetic repulsion. This theory, explaining the phenomenon along gravitational lines and in terms of the "true atom" theory contained in Specification 1,206,260, is the basis for the design of the present small-hole spark-perforating apparatus.

Each hologram is movable between respective first and second end positions, by motor 56, 54 and racks 51 or 52, along the optical axis of its respective channel (i.e. directions 40c or 42c). The image generated by each hologram in its second end position corresponds to the image generated by the re-set sequential hologram at its first end position. The hologram in a given channel is changed when maximum displacement in that channel has been reached. In the embodiment where there are two channels the holograms in the channels move in opposite directions but in phased synchronism. Thus when hologram 34 reaches its maximum displacement channel 40 is blocked and channel 42 and hologram 36 brought into use. Each channel may be monitored, using laser light of a different colour from that of source 32 and to which the display device 30 is not sensitive, and the information fed back to control panel 50. In the simulator the pick-up 30 may be given movement in the X, Y, roll, yaw and pitch directions.

Abstract: 1525810 MOSFET delay circuit MOSTEK CORP 16 Dec 1976 [29 Dec 1975] 52561/76 Heading H3T A delay circuit, Fig. 1, comprises a bootstrapped invertor T1, T2, C, whose input node N2 is coupled to the input 12 via the channel of T3, and precharge means to charge nodes N3, N4 and discharge N1, N2. Operation: Assume both 12 and 16 are at logic O (V ss ). A precharge signal 16 is applied, charging N3 and N4 to V DD  - V T  (V T  = threshold voltage) and discharge N1, N2, and is then removed. Input signal 12 is applied. As node N3 is isolated, it will follow the input signal by the gate-channel capacitance of T3, thus allowing N2 to follow the input signal. When the input 12 has risen sufficiently to turn on both T7 and T10, N4 discharges through T10, which also causes N3 to discharge via T4 (isolating the input from N2), and turns off T2. As N2 is high enough to turn Tl ON, N1 now charges via T1 and as N2 is isolated, its potential rises by bootstrapping through C, turning T1 on even more. N2 rises above V DD  ensuring a rapid turn-on of T1 and a rapid rise in output voltage. T14, T15 and T16 are optional. In another embodiment (Fig. 3) T12 is omitted, the gate of T4 being connected to V DD . In a further embodiment (Fig. 4) the gates of T4 and T7 are connected to N2. A plurality of delay stages may be used in series in a clock generating system (Fig. 5).

It also comprises either a single aerial element which is directed towards the centre of the lens and which is disposed at a point upon its surface, or a single aerial element of extended aperture spanning a great circle of the lens, or a plurality of aerial elements A1 to Aj disposed at points which are regularly spaced around such a great circle. A semi-conductor impedance element is associated with each aerial element whereby the incident waves are reflected back towards their source and may be coded for identification of the reflector. Lifeboats may be fitted with such reflectors, and the arrangements with an aerial element, or aerial elements, extending around a great circle of the spherical lens provide omnidirectional operation in azimuth. As shown in Fig. 4 the aerial elements A1 to Aj are electromagnetic horns, but elements of dipole or spiral type may be used instead. Also, a modulating signal S is shown as fed to the semi-conductor impedance elements D1 to Dj, but in other embodiments said elements are simply connected across their respective aerial elements (Figs. 1 to 3, not shown). In the latter cases discrimination between two reflectors may be obtained by providing one with semi-conductor impedance elements having linear characteristics, so that reflected waves are mainly of fundamental frequency, and the other with semi-conductor impedance elements having non-linear characteristics, so that the reflected waves have higher harmonic components. In a pulse radar system operating in conjunction with a plurality of such reflectors gating means are provided in the receiving section thereof so that the modulated echo signal from a particular reflector may be selected and displayed (Fig. 5, not shown).
