Title: Roof of semi-circular section tiles - interlocking tiles engage between projections on plastic roofing sheet
IPC: E04D12/00
Filed: 1973-07-05
Abstract: The invention is applicable to roofs that are entirely tiles with half round tiles. Battens (5) are fixed to the rafters (6). To the battens is nailed a sheet or strip of plastic (3) which has projections facing upwards (4). The half round tiles that are placed concave upwards rest on these projections. These tiles (2) are intended to carry away rain water. Over these tiles are placed other half round tiles which are concave downwards. The projections prevent lateral movement of the tiles whilst the fact that the tiles have a smaller radius at their lower end prevents them slipping downwards.

Title: Prevention of static build up on dipole antennae - has dipoles connected through a block set conductivity material
IPC: H01Q1/00
Filed: 1974-03-29
Abstract: The method is for mounting aerial dipoles in the form of two quarter wave elements, such that static charges are continually leaked away. The design avoids the use of a leak resistor and consequent loss effects in the H.F. band. The two dipole elements (1-2) may be held rigidly in various configurations. In the simplest case the element (3) into which the dipole ends are push fitted and from which the coaxial cable connections are made via contact screws (7-8) is formed from some metal loaded plastic, providing a finite resistance in the one to 10 kilohm range. The dipole assembly is held in a mounting (4) of some insulating material.

Title: Timing electric arc spot welding - by stopping welding when welding energy reaches set value
IPC: B23K9/10
Filed: 1974-09-24
Abstract: A transducer (1) puts out a signal representing the arc voltage (UA). A second transducer (3) emits a signal (3a) representing the arc current (JA). Both signals enter an analogue multiplier (6) whose emitted signal (PT) represents the total energy input. This enters an adder circuit (7), together with another signal (PD) depending on the heat absorption of metal being welded and signal (PD) is passed to an adjustable voltage source (8). The adder output (PU) represents the welding power required and enters an integrated circuit (11), comprising an amplifier (12) and a capacitor (13), whose output (EU) enters a comparator (14) for comparison with a predetermined signal (EC) corresponding to a good weld. When this level is reached, a relay (18) opens the circuit to stop welding.

Title: Dummy target launched from airship - has flame outlet offset from axis to reduce speed of travel
IPC: F42B5/15
Filed: 1974-12-10
Abstract: A dummy target to be launched from an airship so as to mislead a missile using an infra red tracking system, without travelling ahead too fast, due to the combustion charge propelling the device like a rocket, has the rear part of the cylindrical casing closed by a plate with an eccentric hole through it, acting as the flame jet, this eccentricity causing a turbulence which counteracts the excess speed and also improves the flame. A small hole through the plate permits an ignition charge to be fired to ignite the main pyrotechnic charge inside the casing. The whole casing includes a pulse device actuated externally to cause the ejection and ignition of the device, and including a firing delay. A safety device prevents actuation immediately after launching.

Title: Manhole with several branch ducts - has chordal panels sliding into slots to divide chamber for inspection and cleaning
IPC: E02D29/12
Filed: 1975-07-30
Abstract: The man-hole allows one or more branch ducts to be constructed at any height above the floor, while still leaving the main hole sufficiently clean that it can be used for inspection purposes. The branch ducts can be made at any time after the network becomes operational, and they continue to be readily accessible for cleaning rods. The cylindrical-section interior of the man-hole is divided off into one or more vertical cavities by means of panels which slide into grooves in the outside wall. The wall has thickened slotted areas for this purpose. A space is left between the upper part of the last panel to be put in place and the underside of the man-hole cover, so that the plates can be lifted up while a branch duct is being constructed.

Title: Sideband regenerator for pseudo-ternary coded signals - has carrier synchronised in frequency to digital signal and phase shifted relative to upper sideband
IPC: H04L7/027
Filed: 1976-03-10

Title: Heavy fragile load handling sling - has rubber sheath reinforced by woven fibres of steel or synthetic material
IPC: B66C1/12
Filed: 1976-09-21
Abstract: The sling is particularly for handling heavy and fragile loads, being of steel rope, having a tubular rubber sheath (10, 11) reinforced by woven fibres of steel of natural or synthetic material in one or more layers (8, 9).
