Patent GB-670207-A (GB)
Title: Improvements relating to tubular furnaces
IPC: C10G9/20
Filed: 1949-08-04
Abstract: <PICT:0670207/III/1> A tubular furnace for heating hydrocarbon oils comprises a preheating convection zone 5 in series with a radiation zone 3, and an independent convection zone 8, which is heated by hot gases from the radiation zone passing through a plurality of slide-valves 9 (only one of which is shown).  A main flow of oil is heated in zones 5 and 3, while a subsidiary flow may be independently heated as required, in zone 8.  The furnace is heated by gas-burners 2.  The hot gases flow across zone 3 over bridge 6 and through zone 5, from which they are withdrawn through flue 15 controlled by damper 17.  When valves 9 are open, some of the hot gases from zone 3 flow into zone 8; and they are withdrawn from zone 8 through dampers 18, 19 and flue 16, which is quite separate from flue 15.  The gas supply to the burners may be controlled by a regulator which responds to the temperature of the main flow at the outlet whereby, when the subsidiary zone 8 is shut off, the amount of gas burnt is automatically reduced.  The slide-valves leading to the subsidiary zone may be automatically regulated, using as control means either the temperature of the flue gases leaving the zone, or preferably the final temperature of the subsidiary liquid flow.  The furnace may be used for heating benzolised wash oil when it is often desirable, in addition to heating the main flow of wash oil, to heat a subsidiary flow or to heat the condensate, separated from the water, of the driven-off vapours, when the latter require rectification.  The furnace may also be used for distilling two fractions of tar independently.

[Also in Division B8] In a beverage making apparatus, such as a coffee vending machine, ground coffee, which has been moistened to enable the beverage to be more rapidly extracted, is cooled, to preserve it from deterioration, before a measured quantity is dispensed to a brewing chamber. As shown, ground coffee is stored in hopper 25, from which it is moved by screw conveyer 28, through a tube 30, while water is added at 61 to moisten it. The coffee in tube 30 is cooled by a refrigerated jacket 66. The moist coffee is fed into measuring cup 31 (see Division B8). A brewing chamber 32 has a lid 35 which is held in an open position to receive the coffee from cup 31, as this is swung downwardly and the contents flushed out. The coffee falls on to a section of filter paper strip 37 clamped between cylindrical wall 33 and base 36. Chamber 32 is heated by electric element 136 and is supplied with hot water from tank 26. The water flows tangentially into the chamber. When the lid 35 has been replaced, compressed air from tank 27 drives the liquid through the filter paper to delivery heat exchanger 42. Cream and sugar may be added to cup 43 from containers 45 and 46. On completion of delivery, wall 33 is raised to allow strip 37 to be advanced and the exhausted grounds 40 to be deposited therewith in waste bin 41. With the measuring cup 31 in the raised position and a fresh section of filter paper clamped beneath wall 33, the apparatus is ready for a further operating cycle. A coin-operated control circuit in which a timer motor drives switch-operating cams is shown and described. White or black coffee may be selected by means of a four position switch and, in the event of unsweetened black coffee being chosen, an additional volume of water is supplied to the brew chamber. Switches causing delivery of extra portions of cream or sugar and a drink counter are provided.

The sheets 11, 12 cover the area defined by the target whereby during passage of a projectile therethrough, the projectile is simultaneously in momentary electrical contact with both of the first and second sheets. One sheet is maintained at a constant potential. One of the sheets is divided into a plurality of zones, each zone being spaced from the next by a distance less than the diameter of a projectile and being insulated from adjacent zones (Figs. 3, 4, not shown). The zones and the other sheet are each connected to a separate terminal for connection to an indicating circuit. The sheets may be of metal preferably aluminium, or an elastomeric synthetic plastics material. The electrically insulating layer 10 is of sponge rubber or synthetic foam, the sheets and layer being secured together by an adhesive. Strips of electrically conductive rubber connect the sheets 11, 12 to the terminals respectively. A third electrically conductive sheet may be provided, the outer sheets being divided, one into the zones and the other into sectors, the intermediate sheet being continuous and maintained at a positive potential (Figs. 3, 4, 5, not shown). A projectile passing through such a target makes successively two circuits. Each zone and sector is connected to a circuit by which a receiver including a visual indicator, e.g. a counter and a printer, can compute the score of the shooter and the position, that is the position of the sector, which the projectile has penetrated. Such circuits are described in detail with reference to Figs. 6, 7, 8 (not shown). Also a signal may be fed into the circuit on the firing of a projectile (Fig. 8) to actuate part of the circuit.
