Title: Transport facilities with fluid sustained vehicle
IPC: B61B13/08
Filed: 1967-09-12
Abstract: A transport system comprises a vehicle 37, Fig. 6, movable with a clearance, below a guide track 38, wherein a sub-atmospheric pressure fluid layer 40 is provided in the clearance between the track 38 and walls 42, 43, of the vehicle, the latter being lifted by the force produced by the difference between the atmospheric pressure and the pressure of the fluid layer and wherein means are provided for adjusting the pressure of the layer and thus the lifting force as the clearance varies to thus stabilize the vehicle in its movement along the track. The cylindrical-surfaced track 38 is supported by pylons 39 and provided with a roof 49. The vehicle 37 is provided with wheels 41 which can bear on the track when the vehicle is stationary or the lift fails. The clearance between the walls 42, 43 and the track reduces from their outer ends towards a neck connected to a reservoir 48, Figs. 7, 7a, extending along the length of the vehicle. The sub-atmospheric pressure layer 40 is produced by injectors 44 in the neck, connected by tubes 47 to a duct 46 connected to the exhaust of a gas turbine unit 45 at the front of the vehicle, which duct reduces in cross-section towards the rear of the vehicle. The gases from the turbine unit exhaust freely to atmosphere through the reservoir. The vehicle is propelled by a rear propeller 50 driven by a unit 51. Wheels 55 provide a minimum clearance between the track and the vehicle and may be used if required for braking and propulsion. Tilting of the vehicle laterally, is limited by wheels 53, Fig. 6, engaging a safety member 52 carried by the pylons 39. By the nature of the varying clearance between the walls 42, 43 and the track, the lift is reduced as the vehicle movesnearer the track and vice versa, in the manner described with reference to Fig. 4 (not shown). In another embodiment the control is by a sensing roller, Fig. 2 (not shown). Superatmospheric pressure cushions may also be provided between the vehicle and part of the track or an auxiliary track, to guide the vehicle laterally and/or assist the lift as described with reference to Fig. 3 and 10 (not shown). Exhaust gases may also resist propulsion.

Title: Container closure
IPC: B65D51/16
Filed: 1968-01-24
Abstract: A container closure of resilient material comprises a disc portion 11 and a wall 12 which act as a plug stopper, and an outer skirt 14. When the closure is assembled on a bottle, seals are formed at 22 and 24 and annular indentations 19 allows some flexing of the wall to ensure proper seating of the disc 11. The disc is thicker than wall 12 to give sufficient strength and rigidity for a tight seal. If the container has an inwardly disposed lip on the internal bore the closure forms one of the seals by the lip co-operating with indentation 19. When closures are stacked on each other, head 16 seats on shoulder 17 and a cylindrical portion 18 is a sliding fit in a cylindrical portion 21 thus stopping them sticking together. In a modification, Fig. 4 (not shown), the disc 11 has grooves (30) around the periphery to allow venting of internal pressure from a container interior, the seal formed by the outer skirt acting as a one way valve.

Title: Two to four wire telephone hybrid transformers
IPC: H04B1/58
Filed: 1968-02-23
Abstract: The balancing network 4 of a hybrid transformer circuit, Fig. 2, has variable components 6, and 7, which are adjusted by error signals derived from signals from the upper and the lower parts of the frequency spectrum extracted from both the receiving pair 2 and the sending pair 5 so as to eliminate echoes in the sending pair 5 of signals in the receiving pair 2. Signals in the receiving pair 2 are selected by filters 10 and 11 to extract frequencies of respectively 500 and 2000 c.p.s., which, via phase-shifters 14 and 15, operate gates 16 and 17. The gates inputs are derived from the same respective frequency components in the send line 5 selected by filters 12 and 13 which are alternately connected, by the switches 22a and 22b, to the respective gates 16 and 17, the outputs from which drive, via amplifiers 18 and 19, the motors 20 and 21 to control the values of resistors 6 and 7. Only echo signals in send pair 5 due to signals in line 2 will be effective to drive motors 20 and 21 since all other signals will be uncorrelated. Amplifier 23 prevents signals from the two wire line 3 reaching the inputs of filters 10 and 11 since signals from the two wire line in the send and receive pairs would be correlated. In an alternative embodiment the filters 10 and 11 are replaced by oscillators of the respective frequencies 500 and 2000 c.p.s. which alternately feed signals into the line 2 and also supply gating signals to the gates 16 and 17, Fig. 3 (not shown). The system would be energized for a short time at the commencement of each connection.
