Title: Method and mould for the manufacture of sealed sterile containers from plastics material
IPC: B29C49/46
Filed: 1979-01-26
Abstract: An extruded tubular blank is placed in a mould such that it is divided into two portions 1,4 connected by a conduit 5a coaxial with a blowing needle 6. A first one of the portions 1 is blown to form a container, whereas the second 4 is not blown and remains hot and malleable. The walls of the second portion 4 are then compressed one against the other and welded together to close the blowing orifice 5a. The mould comprises two chambers 3, 4, and a blowing conduit 5, 5a. The blowing needle 6 slides in this conduit 5, 5a in an air-tight manner so as to pierce the blank and inflate solely the first chamber 3. Inflation air is then removed and a flat head 26 driven by a piston 18 then moves in the second chamber in order to crush and weld together the walls of the unblown second blank portion 4. Alternatively the second blank portion may be crushed by compressed air. <IMAGE>

Title: Run-flat Tyre and Wheel Rim Assemblies
IPC: B60C17/06
Filed: 1979-05-25
Abstract: A pneumatic tyre and wheel rim assembly contains a support hoop 2 which supports the tyre if the latter deflates by contacting the inside of the tyre tread at top C and bottom A of the assembly as shown in Fig. 2. The dimensions of the hoop are such that its inner surface does not touch the rims whether the tyre is inflated or deflated, and its outer surface does not touch the tyre when inflated normally. Positioning means (not shown) which extend between the rim 5 and hoop 2 are provided to maintain the hoop in a position substantially concentric with the rim during running of the assembly with the tyre inflated, these means being made, e.g. of brittle foam plastics or an elastomer, so as to break up or deform if the tyre deflates thereby enabling the hoop to assume the Fig. 2 position.

Title: Fault detector
IPC: G06F11/00
Filed: 1979-05-29
Abstract: In a computer based railway interlocking control system, the railway traffic control devices, e.g. points and signals, are arranged to be controlled by signals in one of two possible steady states and the interlocking control means (30, 31, 32, Fig. 2) is arranged to produce control signals in the steady state for de-energised or "safe" device settings and in an alternating state for energised or potentially "unsafe" settings. The alternating control signals (33, 34, 35 or 38) must be converted to the corresponding steady state to operate the devices thus, the converting or restoring circuit discriminates against dormant wrong side failures, i.e. "unsafe" signals to increase the inherent safety of the system. <IMAGE>

Title: Amplifier Reflected Wave Cancellation Circuit
IPC: H03F1/20
Filed: 1979-07-13
Abstract: Back reflection from the load RL in e.g. distributed amplifier, causing distortion or wastage of power, is cancelled by a system in which any reflected wave on the output line 10 gives rise via e.g. a directional coupler DC to a component which is fed to the amplifier input line 11. This in turn produces a wave on the output line 10 travelling in the same direction as the reflected wave and of approximately the same magnitude but opposite sign so as to at least partially cancel the reflected wave. The description relates to a radio transmitter using thermionic valves, but these may be substituted by suitable semiconductor devices. <IMAGE>
