Title: Improvements in fuel tank ventilation in motor vehicles
IPC: B60K15/035
Filed: 1970-11-09
Abstract: 1277326 Venting fuel tanks FIAT S p A 9 Nov 1970 [14 Nov 1969] 53109/70 Heading F1B [Also in Division B8] A motor vehicle has a fuel tank having a number of spaced-apart holes in its upper surface, a tube leading from each hole to a manifold, a duct convecting the manifold to a fuel vapour trap which is purged by air subsequently fed to the engine and a normally closed valve which controls communication between the tank and the atmosphere, each tube leading from a hole to the manifold consisting of two parts inclined to each other, the first part slanting upwardly from the hole to a point above the tank opposite that hole and being connected to a container situated between the two parts of the tube and having a volume larger than that of the first part of the tube. A hole 8 in the tank is connected by tube 12 to manifold 15, the first and second parts 20 and 21 respectively being joined by a container 22. The part 20 is connected to the container by an elbow 28 which has a constricted bore at its lower end. The second part 21 is joined to the container by a connection piece 30 which enters the uppermost part of the container. A similar tube and container assembly connects the hole 9 to the manifold. A pipe 36 connects the manifold to a valve 38 which opens to adjust filtered air to the tank if the pressure therein drops below atmospheric. Valve 38 also vents the tank if accidental severe over-pressure occurs. For slight over-pressure vapour from the tank passes through the valve 38 to an activated carbon trap 16. Air for purging the trap is drawn from the air-filter 18 and is fed by a tube 19 to the intake manifold. Should liquid fuel enter one of the pipes due to abrupt dynamic forces resulting from the motion of the vehicle, the liquid must first traverse the first part of the tube and the rate at which it can enter the container is controlled by the constriction in the elbow 28. The volume of the container is at least equal to the volume of the first part of the tube, so that fuel reaching the container can be held there until it drains back to the tank.

Abstract: 1349266 X-ray control systems SIEMENS AG 25 Nov 1971 [25 Nov 1970] 54876/71 Heading H2H An X-ray installation comprises a plurality of X-ray units respectively associated with a control unit so as to control the X-ray unit by way of a common supply unit, each of the control units having a selector device to select the mode of operation of the associated X-ray unit and a manually operable switch which enables the associated X-ray unit to be connected to the supply unit whilst at the same time preventing any of the other X-ray units from being connected to the supply unit. Three X- ray units 1, 2, 3, having differing radiological uses, are connectable to a common supply unit 4; each X-ray unit being provided with a control unit 5, 6, 7 respectively. The installation further includes an inhibiting unit 13 and a central control desk 17 which is connectable to the supply unit 4 in place of the control units 5, 6 or 7. The desired exposure parameters for the X-ray units 1, 2, 3 are settable by the keys 8, 9, 10 in the control units 5, 6, 7 and each of these control units has an override key 14, 15, 16 respectively by means of which the control desk 17 is connectable to the supply unit 4 in which ease the exposure parameters are settable by devices 18-26. Formally the control unit 5 of the X-ray unit 1 is connected to the supply unit 4 by way of a closed contact g of relay G and a closed contact a 4  of relay A the X-ray unit 1 being connected to the supply unit 4 by the closed contact a 1  thereof, the control units 6, 7 being disconnected from the supply unit by means of open contacts b 4 , c 4  of relays B, C. If now it is required to connect control unit 6 ofX- ray unit 2 to the supply unit 4 a switch 11 in the control unit 6 is closed manually. Relay B is then energized to close contacts b 4 , b 1  thus connecting control unit 6 and the X-ray unit 2 respectively to the supply unit 4. At the same time contacts b 2 , b 3  are closed to energize relays D, F. Energization of relay D opens contact d to de-energize relay A thus opening contacts a 4 , a 1 , to disconnect control unit 5 and the X-ray unit 1 respectively from the supply unit 4. Energization of relay F opens contact f which prevents energization of relay C thus preventing the connection of control unit 7 to the supply unit 4. Closure of a manual switch 12 in control unit 7 has a similar operation. Operation of the override key 14, for example, energizes the relay G to operate the contact g whereupon the control unit 5 is disconnected from the supply unit 4 and the control desk 17 connected thereto. Operation of override keys 15, 16 perform similar functions.
