Abstract: 1324168 Valves IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Dec 1970 [31 Dec 1969] 63516/69 Heading F2V A rotatable plug valve has a valve member 72, 76 with a flow port or a peripheral flow passage 74 which co-operates with one or more body ports 71. At least that part of the plug adjacent a port 71 in the closed position of the valve, is formed from a pliable material, and is provided with a blind indentation or recess which overlies the port. Creep of the pliable material into the port, and tearing, are thereby avoided. The pliable material contains at least 60% by volume of a low-friction fluorine-containing polymer e.g. P.T.F.E.. polychlorotrifluoroethylene, polyvinyl fluoride, polyvinylidene fluoride, or copolymers of P.T.F.E. containing ethylene or hexafluoropropylene. The area enclosed by the indentation may be from 10% to 30% greater than the area of the port. As shown, the plug consists of an outer cylindrical portion 72 of P.T.F.E. and an inner plug 76 of elastomeric material which is compressible e.g. by a headed stem 77, 78 screwed into a button 79, to expand the outer portion into sealing engagement with the body. In modifications, the inner plug is compressed by a screw (50) or simply plugged into the outer portion, Figs. 4 and 6 (not shown). The valve may be of multiple-way type, Fig. 8 (not shown). In other embodiments the plug is conical and made in one piece of P.T.F.E. The plug has an integral handle 73.

Abstract: 1352799 Steering column locks HANS KOLB KG 27 Oct 1972 49544/72 Heading B7J [Also in Division E2] A steering column lock having a bolt which is spring urged into a locking position and retained in a disengaging position until removal of a key from a cylinder lock of which a barrel is rotatable to retract the bolt into the disengaging position and then to actuate a starter switch and is also axially displaceable to release the bolt and allow the bolt to move into the locking position on removal of the key, the barrel being axially spring loaded in the direction of removal of the key and being provided with at least one control member 11 which is movable radially with respect to a barrel housing 3 and is engaged by the key and engages with a respective control surface 13 of the housing to control the axial displacement of the barrel on removal and ininsertion of the key in which at least one pin 6 is provided, axially displaceable in the housing and transmitting the thrust from the or each spring 4 that axially loads the barrel by abutting the barrel when the barrel is in its locking posiposition, and the barrel abuts the or each pin through a cam face 8 shaped so that, while the barrel is being turned from a drive position to actuate the starter switch and when it is returned to the drive position by a return spring, the pin or each pin abuts the housing instead of the barrel so that the barrel is relieved of the loading of the or each axially acting spring. As shown in Fig. 2, the key is inserted into the lock to move the barrel axially, the barrel being retained by the control member 11 abutting surface 13 of the housing against the action of the springs 4. When the key is turned through 90 degrees, Fig. 3, the barrel turns to the drive position and the bolt is retracted, the cam face 8 allows the pins 6 to be displaced under the action of the springs. The pins engage the housing 3 instead of the cam face thereby relieving the barrel of the load of the springs, thereby ensuring that the barrel is easily returnable from the starting position to the drive position by its return spring. The control member instead of engaging one edge of the key may engage a flat surface. There may be two control members. The barrel may have an end projection 15 which fits into a notch in the housing whereby the barrel may only be turned after the barrel has been moved axially. The control member can also function as a tumbler of the lock.

Title: Techniques for protection of data communication networks
IPC: H04L12/22
Filed: 1999-03-11
Abstract: A method for transmitting data between origin network and destination networks where each network has a network front end and accepts conforming to a first protocol (20) and a second protocol (30). Data is transmitted over the origin network to the front end of the origin network and then the data is transmitted from the front end of the origin network to the front end of the destination network over at least one primitive network. When an ultimate destination of the transmitted data is not the destination network, the data is transmitted over the destination network to the destination using the second protocol (30). When primitive network includes an intermediate node (200), the data is transferred from the origin network to the intermediate node (200) and from the intermediate node to the front end of the destination network. The intermediate node can be electrically isolated from the front end of the destination network when the data is transferred from the front end of the origin network to the intermediate node, and then electronically isolated from the origin network when the data is transferred from the intermediate node to the destination network.

Patent IL-224219-A (IL)
Title: Personal aircraft
IPC: B64D/
Filed: 2013-01-14
Abstract: A safe, quiet, easy to control, efficient, and compact aircraft configuration is enabled through the combination of multiple vertical lift rotors, tandem wings, and forward thrust propellers. The vertical lift rotors, in combination with a front and rear wing, permits a balancing of the center of lift with the center of gravity for both vertical and horizontal flight. This wing and multiple rotor system has the ability to tolerate a relatively large variation of the payload weight for hover, transition, or cruise flight while also providing vertical thrust redundancy. The propulsion system uses multiple lift rotors and forward thrust propellers of a small enough size to be shielded from potential blade strike and provide increased perceived and real safety to the passengers. Using multiple independent rotors provides redundancy and the elimination of single point failure modes that can make the vehicle non-operable in flight.
