Title: Connectors or termination members for electric cables
IPC: H01R13/621
Filed: 1946-11-15
Abstract: 623,649. Two-part couplings. BOSWELL, 1. I. Nov. 15, 1946, No. 33994. [Class 38 (i)] [Also in Group XXVIII] A cable-connector consists of identical terminal members, each comprising segments of coaxial cylindrical shells. Each terminal member may have two opposed semi-cylindrical shell portions 1, 2 and a semi-circular flange 4, Figs. 3, 4a, a sleeve comprising a pair of semicircular members 5 fitting over this flange so that when connection is effected the two members 5 can be rotated through 90 degrees to engage ends 8 of springs 7 in recesses 10 in the flanges, thus forming a collar holding the two terminal members together. The springs 7 are welded to the collar members 5 and normally engage grooves 9 on the peripheries of the flanges 4. In a modification, Fig. 5, electrical connection is effected between silverplated plugs 14 and sockets 16, each pair of which is fitted into a stepped insulating bush. The cable sheath if conductive, is soldered to a metal plate 11 insulated from the cores by a plate 12 and bushes 13. The terminal is completed by a member 24 screwing over the thread 23 on a member 19 receiving the stepped bush and having semi-cylindrical extensions, the outer extension being threaded at 22. A clamping segment 25 secures the member 24 to the cable sheath and locking is effected by screwing collars 27 of each terminal on to the threads 22 of the opposing terminal, Fig. 7. A contact for a single-cored cable comprises silver-plated tongue 30 and spring 31, Fig. 6b.

The wires 4 are tensioned by drawing off bobbins having spring brakes. In a modification the wires 3 are also drawn off bobbins and the mould is modified to supply material also to the groove 9 nearest these bobbins so that when the pieces 14 are moulded on the crossed wires a bar 8 is also moulded on the wires 3. After severing these between the pieces 14 and bar 8 the finished ribbon is moved as before to its next position and the bar 8 is moved from its groove 9 to the groove at the opposite side ready for the next moulding operation. In another modification, both sets of wires 3, 4 have pairs of bars precast on them. The number of wires or threads and the angle of crossing may be' varied. Materials suitable for moulding are thermoplastic synthetic resins, e.g. that known under the Registered Trade Mark " Trolitul," thermosetting synthetic resins which first become plastic by heating, e.g. that known under the Registered Trade Mark " Bakelite," and cementitious material which quickly sets. Specification 377,621 is referred to.

Abstract: 961,793. Weighing apparatus. W.KRAUT. Sept. 11, 1962 [Sept. 21,1961], No. 34645/62. Heading G1W. In a pendulum type weigher the basic price of a commodity is set up and then on the basis of such price the balance automatically determines the weight and sale price of the commodity being weighed. A weigh beam 11 (Fig. 2) fulcrumed on _ knife edges 12 supports on one arm a weigh pan 17 and on its other arm a pan 15 for tare calibration. Oscillation is damped by a dash-pot 20. Rigidly attached to the beam is a pointer 22 and a pendulum weight 23 which is of such a weight that e.g. a 1000 g article in the weigh pan corresponds t to maximum deflection of the pointer. The weight 23 is elongated and has a straight edge 24 (parallel to a hypothetical line 24a passing through the fulcrum edges 12) for co-operation with a detecting element 34a on a follow up weight detecting carriage 34, and a detecting element 53 on a follow up sale price detecting carriage 47. The carriage 34 moves along a bar 33, which is perpendicular to the half load position of the line 24a, moved by an endless steel strip 35 running over a roller 36 and drum 37. Engaging the drum 37 is a draw element 39 which, by virtue of a weight 40 suspended on it, rotates the drum and pulls the carriage to urge the detecting element 34a against the edge 24 of the pendulum weight 23. A weight indicating scale disc 44 rotates with the drum 37. The carriage is returned to its no load position by a motor 41 which rotates the drum 37 against the pull of the weight 40. The price carriage 47 operates similarly and runs on bars 46, 48, its movement being conveyed to a price scale disc 65. The distance of its detector element 53 from the fulcrum edges 12 is adjustable however and the position thereof is selected and set according to the basic price of the commodity. Adjustment is carried out when the carriage 47 is at the sub zero position by means of a fork 77, on a carriage 68 movable on a frame member 66 by a steel strip 67, the fork engaging a ball 78 on the basic price member 52. At the same time the strip 67 moves a basic price scale disc 72 so that within the area indicated at 45 the corresponding weight, basic price and sale price are indicated, and can be printed on a label (not shown).
