Title: Method of placing undersea piping - uses collapsible fluid filled tube gives buoyancy to prevent kinking of piping
IPC: F16L1/16
Filed: 1974-02-04
Abstract: It is necessary to decrease the weight of undersea piping during laying to prevent the formation of sharp radius curves and subsequent kinks. As the piping (3) is fed from the stern of the ship it is coupled to a flexible support tube (11). The tube is fed between rollers (5) (sealing the tube) and is connected to two switched fluid reservoirs, one containing water (P) and the other buoyant fluid (S), with specific gravity less than that of water, and immiscible with water. The tube is initially filled with buoyant fluid but as laying proceeds, the support tube is gradually filled with water, this lying in the part on the sea bed and the buoyant fluid giving support in the part between boat and sea bed.

Title: Anti-jamming method for an electronic scanning aerial and aerial obtained by applying the method
IPC: H01Q3/38
Filed: 1974-02-12
Abstract: The method counters the jamming of an electronic scanning aerial with digital control of phase-shifters inserted into the supply lines of the elementary sources. The phase shifts of each phase-shifter are successively modified by the addition and then subtraction of the displayed phase shift of an elementary value of phase shift. For each of the values obtained, the level of the received signal is measured. A comparison of these levels for each phase-shifter enables the value of the phase shift for which the measured level is a minimum to be maintained. For a given aerial, this produces an optimum phase law giving a radiation pattern with dips in the direction of the jammers.

Title: Blow moulding tool with intersecting parison and cavity tool motions - to reduce cycle times and sustain parison support
IPC: B29C49/06
Filed: 1975-10-17
Abstract: A blow moulding tool incorporating a core mounted on a stationary press platen and a cavity tool mounted on a rising platen and including an injection gate via which a parison is moulded to surround the core. When the cavity tool has been raised clear, two ancillary split mould shells converge laterally to enclose the parison. Air is then injected around the base of the head of the core to dilate the parison to fit the larger cacity of the split shells. The shells then part to allow a stripper ring around the base of the core to rise and disengage the moulding from the core. The equipment is compact and quick cycling and does not involve lateral shifting and associated chilling and draping of the parison prior to dilation. The shell movement may be linked with the press platen movements or power system.
