[Also in Division H4] In a test jack comprising a plate carrying two sets of terminals connected in pairs by contact springs, which connection can be broken by inserting a separating plug between the contact springs, the terminals are formed of straight strips and the two sets of terminals are connected to their respective contact springs in the upper and lower parts of the plate respectively. As shown, pairs of terminals 9, 9a, 10, 10a, 11, 11a are mounted on a plate 8 and are connected together by pairs of wire springs 12, 12a, 13, 13a, 14, 14a to which they are soldered. Recesses 17, 17a are formed in the edges 15, 16 of the plate and the terminals are bent into these recesses so that they are flush with the surface of the plate, so enabling the plates to be moun - ted in slots in a housing to reduce the ingress of dust.

Slow-wave-structures constituted by an array of conductive vanes projecting from a conductive wall and interconnected by a helix, as disclosed in Specifications 1,151,069 and 1,151,070, are modified, to provide an increased interaction impedance with an electron stream, by connecting the helix to the vanes at an intermediate point along the length of the vanes, such that the spacing from the helix to the wall is between one third and three times the spacing between the helix and the free ends of the vanes. As described, the structure includes a pair of oppositely wound helices mounted one either side of the vanes at their mid-points, and is employed in a crossed-field travelling wave amplifier having a curved slow-wave-structure constituting the major arc of a circle, but reference is also made to its use in a linear beam tube.

Abstract: 1,231,052. Making tube banks; coiling helices. BABCOCK & WILCOX Ltd. 23 May, 1969 [24 May, 1968], No. 24998/68. Headings B3A and B3E. Apparatus for forming a coiled tube bank in which a cylindrical core 10 together with end flanges 12 are positioned between a headstock 2 and tailstock 4. A first layer of spacer bars 16 is secured to the flanges 12 and held in rigid abutment with the core 10 with steel strapping. A hoop 48 is welded to the spacer bars at the end intended to form the inlet of the bank, from which end coiling is started, and a split bush 50 bolted to the hoop. For a two-start initial tube layer the ends of two straight tubes are connected to split bushes 50 and positioned between a pair of guide rolls 22 and 24. Back-up shoes 44 are positioned with steel strapping between the spacer bars 16 and core 10. The core is then rotated so as to wind the tubes on to the spacer bars whilst at the same time retarding the pressure roller 24 to a speed appropriate to the coiling diameter, to overcome the effect of spring-back forces, and traversing the guide rollers to give the required pitch. As the coil forms along the core 10, the steel stripping is removed and the back-up shoes moved along the core. When the end of a tube is reached the machine is stopped, one of the tubes clamped to a spacer bar, and if a tube bend is required the location of the bend is marked and coiling continued for about 15 cms. beyond the mark. The tube is then cut and the procedure repeated for the other tube after which the tubes are bent 90 degrees to produce axially extending tube tails. The next layer of spacer bars 16 are then bolted to the end flanges and held in position of the initial layer using steel strapping and the procedure repeated. If it is required to have equal lengths of tube in each pass, the number of tubes in each layer are increased progressively.

[Also in Divisions G4-G6] In a production process information about objects being carried along a conveyer line from one processing station to another is stored in a central store 2, data relating to each object being at a specific information address, position storage units 3, each corresponding to one of the stations, receive the address codes in turn from output 9 and pass them to the next unit as the object moves along the conveyer, each position storage unit by connection 13 causing the data relating to the object to be passed over line 15 to a control unit 4 at that station. A signal on connection 14 routes the data to the correct unit 4. Transfer of an address code from one unit 3 to the next is controlled by transducers 5 and 6 detecting the arrival of the object at the corresponding station, transfer signals being applied over line 10. Each storage unit consists of a number of storage elements one for each bit of the address code and each is preceded by a gate enabled by the signal on line 10. Input 11 resets the store. During transfer the inputs to the storage elements are compared with the outputs, and the previous unit is reset by a signal on output 12 only if there is agreement, showing that the transferred data has been correctly registered. In the case of disagreement an alarm is given. Information is entered into store 2 from input units 1 which receive manually or otherwise data concerning size, weight, grade &c. of the objects to be processed.

[Also in Division F2] A device for use in withdrawing samples of liquid from the interior of a vessel 11 comprises a first assembly 10 adapted for engagement with the vessel 11, and a second assembly 12 which is movable relative to a housing part 14 of the first assembly so as to move a movable part 23 of the first assembly, and move a ball 18 towards and away from a seat 19. The head of the part 23 is polygonal in cross-section and is received in a similarly shaped opening in disc 34 secured to member 28 of the second assembly. A flange 29 is secured to the member 28 and is adapted to receive a sample receptacle 13. In one use with a vacuum existing within the vessel 11 a vacuum greater than that in the vessel is induced in receptacle 13 via pipe 33. The member 28 is rotated, for example by using a wrench engaging flats (27) (Fig. 4, not shown) to open the valve formed by the ball 18 and seat 19. Thus a sample will flow into the receptacle via passages 16, 17, 25 and 24. Alternatively the part 23 may be moved prior to the introduction of a vacuum in the receptacle 13, so that the ball 18 will in this case move downwardly only when the pressure in the receptacle is reduced to a certain value, and flow of liquid will only occur when the vacuum in the receptacle is higher than that in the vessel 11. The pressure inside the vessel may alternatively be atmospheric or super-atmospheric. In alternative forms of the device the receptacle may include a neck which is internally of frustoconical shape for engagement with a suitably shaped extension of the member 28 (the flange 29 being unnecessary in this ease) or with the member 28 itself. In this case the pipe 33 may be connected directly to the member 28 or to the receptacle. The device may be provided with heating means, for example electric resistances, or pipes through which a heating liquid or gas is circulated.
