Abstract: 1491728 Moulding plastic containers O RAKOVSKY 20 Dec 1974 [4 Feb 1974 31 May 1974] 55259/74 Heading B5A A tubular container with an end face and a tubular skirt depending therefrom (Fig. 3) is produced from a length of tubular thermoplastic material by sleeving the said length over a mandrel 12 with an end portion extending beyond an end of the mandrel and softening the end portion by heating without the end portion touching the source of heat; e.g. by one or more jets of hot air as shown in Figs. 2, 5 and 11. The heated end portion is inwardly constricted by applying a force thereto. This can be by creating a lower pressure within the end portion as is shown in Fig. 2 or by mechanical means of a wheel or folder as is shown in Figs. 5 and 11 respectively. A cap is then urged against the end face of the mandrel over the material of the heated and constricted end portion so as to mould the end face of the container between the cap and the end of the mandrel.  Apparatus described in relation to Fig. 14 (not shown) and comprising a rotating turret of four mandrels which co-operate with a flaring tool and feed the sleeves on to the mandrels 12. may also be used.

In the multicavity magnetron shown, the multipactor electrodes 8 and 11 are formed on the top edge of the vane 2 and on the end flange 7 of the anode, electrode 11 being insulated therefrom to permit variation of its D.C. potential via lead 15. A similar arrangement may also be associated with some, or all, of the other vanes, as shown, independent adjustment of the different multipactor elements providing a corresponding set of possible frequency settings. A degree of continuous tuning may be achieved by using D.C. voltages which reduce, without extinguishing, the multipactor discharge. In modified arrangements the multipactor electrodes are disposed at the lateral edges of adjacent vanes (Fig. 4, not shown); or the arrangement of Fig. 1 is modified by the electrodes 11 being mounted on portions of a re-entrant slow-wave structure (30, Fig. 5, not shown) spaced from the end of the anode or otherwise coupled to it (Fig. 6, not shown); or the multipactor elements may be mounted within (Figs. 7 and 8, not shown) the outer coaxial cavity of a coaxial magnetron or-as shown in Fig. 9-at the edges 80, 81 and 82, 83 and 84, 85 of slots 86 formed in its outer wall 59. In a further arrangement, the leads 15, 16, 17 of Fig. 1 are replaced by D.C. energized solenoids (20, 21, 22, Fig. 3, not shown) surrounding the insulator 12, to control or extinguish the multipactor discharge by magnetic field.

Abstract: 1474385 Data processing systems INTERNATIONAL COMPUTERS Ltd 11 Dec 1974 [14 Dec 1973] 59311/73 Heading G4A Functional units 12-14 are connected to a main highway 10, and processing modules 11, each including a processor 16, a port unit 19 and further functional units 17, 18 are connected to the main highway 10 via the respective port unit 19 which detects when addresses appearing on the corresponding processing module internal highway 15 do not pertain to functional units within that module and passes such address on to the main highway 10. A processor 16 supplies an address as two successive bytes on its internal highway 15 and data transfer takes place (internally of the processing module) in the following clock cycle. If an address placed on a highway 15 does not pertain to any of the functional units in the relevant module 11, the associated port unit 19 detects the absence of a ready signal from a responding unit on bus 15 during a period of four clock cycles following the appearance of the first address byte and reproduces the address and any associated control codes and data on the main highway 10 during successive clock cycles after its request for access to the main highway has been granted by a control unit 22. In the case of a read operation, a ready signal from the addressed functional unit causes the port unit involved in the transfer to register the read data on highway 10 and place it on the associated highway 15. Each processing module 11 includes a queue store 20 containing pointers to storage blocks in random access memory units 12. When data or instructions are to be passed from one module 11 to another, the originating module places the message in an available storage block, pointed to by the first entry in a queue store 14, and places a corresponding pointer in the queue store 20 of the intended destination module 11. On completing each current job, a module 11 uses the first entry in its queue store 20 to gain access to the corresponding message in a memory unit 12. When a storage block is no longer required by a module 11, the corresponding pointer is replaced at the end of the queue in store 14. Queue stores 20 may have the same internal address (from highway 15) but must have different external addresses (from highway 10). The lengths of the queues in stores 14, 20 may be monitored to assess system performance. The functional units may be fabricated on separate LSI chips, though a port unit 19 and store 20 may be combined on one chip, and highways 10 and 15 are preferably electrically identical to facilitate interchanging the functional units. The arrangement also allows a high degree of independent parallel processing to be performed.
