Carbon black is produced by incompletely combusting a hydrocarbon feedstock with a free oxygen-containing gas in an enclosed chamber in which the pressure is maintained at 1-100 mm. Hg. above ambient atmospheric pressure, the combustion being controlled so that a substantially stable non-turbulent upwardly extending flame is produced which is enveloped in a thick cloud of smoky combustion products over the uppermost 25-90% of its length. The feedstock comprises hydrocarbon gas or vapour, preferably of a C 2-5  unsaturated hydrocarbon, and in addition liquid hydrocarbons may be sprayed into the flame. In the figure, the burner 14 is supplied with feedstock via conduit 16 and with free oxygen-containing gas or nitrogen via conduit 18, and free oxygencontaining gas is introduced via conduit 20 as necessary.

Title: Improvements in or relating to liquid fuel dispensing apparatus
Inventor: CROXFORD JOHN FRANCIS
IPC: G01V3/10
Filed: 1963-10-10
Abstract: 1,036,930. Dispensing liquid fuel. WAYNE TANK & PUMP CO. Ltd. Jan. 11, 1965 [Oct.10, 1963], No. 39983/63; Heading A4T.  Liquid fuel dispensing apparatus includes a dispensing nozzle provided with electrical detector means operative to permit or prevent flow of fuel according to whether or not the nozzle is inserted in the metallic filler tube of a fuel tank. The detector means comprises an exciter coil energized with alternating current coupled with a detector coil and a compensator coil, the degree of coupling between the exciter and detector coils being reduced when the nozzle is inserted in the filler tube and the e.m,f, in the detector coil being thus reduced. If the nozzle is of aluminium, a lagging e.m.f. induced in the detector coil results in a phase change in the detector coil current which can be compared with a standard if the voltage reduction is insufficient. To enable the detecting means to distinguish between the nozzle boot of the dispensing apparatus and the filler tube the nozzle boot may be provided with a pick-up coil in which an e.m.f. is induced by the exciter coil to prevent operation of the petrol switch relay.

Filed: 1957-12-31
Abstract: 850,404. Jet-propulsion plant. BERTIN & CIE. Dec. 31,1957 [Jan. 9, 1957], No. 40447/57. Class 110 (3). A silenced jet propulsion nozzle comprises lateral air conduits extending obliquely relative to the axis of the nozzle and a gas discharge passage having its inlet located between the air conduits and its outlet completely surrounding the air conduit outlets. The jet-propulsion nozzle 1, Fig. 1, is terminated by an orifice 2 in the form of a flattened annular slot. A surface 3 of double curvature forms two lateral conduits 4, 5, which lead atmospheric air to the oblong orifice 2b. Streamline struts 3a support the surface 3. The air is accelerated in flowing from the intake orifices 6, 7 to the outlet orifice 2b. A small portion of the exhaust gases are discharged through the orifice 8. This increases the suction and acceleration of the atmospheric air without increasing the noise. The orifices 6, 7 may draw in atmospheric air directly or this air may be drawn from the various surfaces of the aircraft. The cooling of the surface 3 is sufficient to cool the nozzle when a reheat system is installed.

Abstract: 1448141 Automatic banking system; cash dispensing MOSLER SAFE CO 30 Aug 1973 [1 Sept 1972] 40952/73 Heading G4H An automatic banking system comprises apparatus for performing banking transactions in response to the presentation of a user-identifying device (e.g. a card bearing data as in Fig. 2) containing information relating to one or more of a plurality of accounts of a user of the system. The transactions may be the deposit or withdrawal of cash and/or the transfer of funds from one of the user's accounts to another. The user is allowed a fixed amount 10 of credit in any period 12, and the balance 11 for that period and the date 13 on which the card can next be used after the limit 10 has been reached is updated after each transaction. A control code 26 (e.g. 40, Fig. 4) causes the system to make available to the user those transactions to which he is entitled (e.g. DEPOSIT, CASH FROM SAVINGS, Fig. 5). The card is inserted in a reader 68, Fig. 6 (not shown), located in, e.g. a cash dispenser (40) linked to a processor 145, Fig. 10 (not shown). The data thereon is read, stored and compared with data stored in the processor. If the card is found to have expired, or to have been stolen or duplicated without authorization, then it is retained by the apparatus. If use of the card has not yet been authorized, it is returned and an appropriate message is displayed on a panel (60). If the card is valid, then a keyboard (57) is enabled and "enter code" is displayed. The user then enters a code which is compared with one derived from the data on the card. If this is correct, the transactions available to that user are indicated by the illumination of function selector buttons (42), and "select transaction" is displayed. The user presses the required button (42), which enables transaction amount selector buttons (54) (cash) or keyboard (57) (transfer or deposit), the amount being displayed, and the apparatus effects the required transaction, the cash is dispensed if required, "select another transaction" is displayed, and the user can repeat the process a given number of times. The above process is described in detail with reference to the flowcharts of Figs. 7- 9, 11-16 (not shown).

A combustion process at a steel converter is controlled in accordance with the amount of sensible waste heat per unit time in the waste gases. This heat is measured by measuring the rise in temperature of a coolant flowing through a conduit 20 in the hood 4 of the converter 2 at at constant rate. The conduit 20 is located between the by-pass air inlet 30 and the waste heat boiler 5, and the exhaust fan 11 and secondary air blower 33 are controlled in accordance with a signal from a device 25 measuring the rise in temperature of the coolant as it passes through the conduit. A sleeve controlling the by-pass air may also be adjusted in accordance with signal from the device 25, and this signal may be used to terminate the blowing process automatically. The coolant conduit may be secured to the blowing lance 1 or may form the cooling jacket of the lance, but is shielded from the effect of combustion of the waste gases with the by-pass air.

Abstract: 928,725. Charging and discharging capacitors. SIEMENS-SCHUCKERTWERKE A.G. Dec. 1, 1960 [Dec. 2, 1959], No. 41442/60. Class 38 (4). In an electric impulse current installation comprising a load 6, such as a vessel through which a plurality of parallel connected capacitors C1-Cn are discharged, the discharge being initiated by spark gaps FS1-FSn having starting electrodes c, an additional capacitor Cs having a reverse polarity voltage is connectable across the load. Without capacitor Cs, if only one gap e.g. FS1 strikes, the voltage across the other gaps is reduced. The additional potential from capacitor Cs increases the available striking voltage across the gaps and assists the striking of these gaps. The capacitor Cs may be charged to a higher voltage and may be of lower capacity than the other capacitors C1- Cn to minimize the reduction of available energy from the other capacitors. It is stated in the Specification that owing to the more simultaneous discharge of the capacitors C1-Cn the peak energy discharge through the load G is higher than without the capacitor Cs.
