Abstract: 1,133,086. Combine harvesters. TEXAS INDUSTRIES Inc. 17 Nov., 1965 [27 Nov., 1964], No. 48936/65. Heading A1F. A harvesting machine comprises a cutting or pick-up mechanism, said mechanism having at least two adjacent portions mounted for pivotal movement relative to each other, and the lower sides of the portions having end parts which are adjacent each other in the working position of the portions, a joining means being provided that is between the portions in their working positions and that carries a member which member, in said working position of the portions, serves to guide crop into the machine. As illustrated the harvesting machine is a combine which comprises two header portions each including a framework 15-17 (Fig. 7) supported on an elevator housing 5 and movable relative thereto about an axis afforded by pins 13, 19 by a hydraulic ram. The joining means is constituted by a triangularly shaped element 33 attached to the elevator housing and the member is a detachable tapering portion 38. Each header portion comprises an auger 44 supported at its outer end in side wall 31, and at its inner end by a beam 52 (Fig. 6), the auger further including reciprocating tines 57. Each portion has a strip 41 of elastic material which, in the operative position, contacts the element 33 to form a seal therewith. A reel 70 supported by members 67, 69 is resiliently mounted on rod (72) by a spring (75) (Fig. 2 not shown) for vertical movement by a hydraulic ram 73. Drive is transmitted via shaft 77, telescopic shafts 82, gear boxes 83 and chain and sprocket mechanisms. The header portions and elevator housing are movable vertically by hydraulic rams 98, and the height of the cutter bars above the ground is also controlled by rams acting through ground engaging wheels 63. When the portions are pivoted, relative to housing 5 strips fixed relative to the housing engage plates 76B thus to force the wheels against the bias of springs (75) towards the base of their corresponding portions.

Abstract: 1,019,176. Ball joint assemblies. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 23, 1963 [Jan. 10, 1963], No. 50699/63. Heading E2F. A joint assembly comprises a pair of relatively rotatable members, an open mesh sleeve of a self-lubricating plastics material in relative movable contact with one of the members and an elastomeric bushing held under load between the sleeve and the other of the members. In one embodiment the assembly consists of a ball portion 14, together with an elastomeric bushing 22 held under load between an openworked self-lubricating plastics liner 19 and the socket 12, the amount of load being sufficient to interlock the bushing and the liner, and to urge the liner into relative surface movement with the ball portion 14. The joint is constructed by first placing the open-worked liner 19 over the ball portion, passing the elastomeric sleeve 23 over the liner and inserting this unit in the socket 12. The sleeve is so constructed that it is longer than the inner surface 16 of socket 12 when in abutting relation with the in-turned shoulder 18, so that when a cap 26 is forced in position and held there by peening over the edge 28, the sleeve 23 distorts to form two shoulders 32, 33 causing the liner 19 to be held against ball portion 14 and additionally ensures that no relative movement takes place between the liner and sleeve 23. In a second embodiment Fig. 4, (not shown), the subassembly of which consists of an inner perforated, longitudinally split metal sleeve 53 in engaging contact with an elastomeric bushing 57, and an open-worked liner 56 of self-lubricating material in bearing contact with the inner surface of the outer member 43 the bushing is put under load during construction by forcing a tapered arbor 66, Fig. 5, (not shown) through the inner sleeve 53, axial expansion being prevented by end abutment 45 and annular retaining ring 58. The load on the bushing is sufficient to effect interlocking engagement with the inner sleeve 53 and the liner 56. Lubricant such as grease may be used to assist the self-lubricating liner.

Abstract: 526,114. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. March 7, 1939, No. 7409. [Class 40 (v)] The "dot" and " dash " signals of an overlapping-beam navigational system are filtered and rectified in a bridge circuit 13, 14, Fig. 2, which is transformer-coupled to the amplifier 6, the resulting pulses being fed to the fixed coil 16 of a dynamometer 15. At the same time, part of the original signal is fed through a resistance 12 in the anode circuit of the amplifier, and through a condenser 18 which blocks the DC component, to the moving coil 17 of the indicator. The object is to produce a steady deflection, corresponding to the bearing-line in a system in which the signals (dots and dashes) are commuted over unequal periods. The indication is not affected by any lack of balance in the circuit components due to temperature-variation or other causes. Fig. 3 shows the signal voltages at different points. Curve a is an original " dot " signal, and b the form in which it appears in the coil 17. The same signal is shown at c before, and at d after it has passed through the rectifler. The curve g shows that the product of the first impulse marked 1 in curve d and the wave b is greater than the product of the second impulse 2 in curve d and the same wave, so that a " positive " deflection is given.
