Abstract: 1,206,481. Deflecting propulsion jets. C. D. HOPE-GILL. 25 Oct., 1967 [26 Oct., 1966], No. 48626/67. Heading B7G. [Also in Division F2] The jet issuing from the nozzle outlet 13 of a jet propulsion power plant 10 can be deflected by a deflecting member 23 having a convex surface 25 extending transversely between two side walls 26, 27 between which the jet is directed so that it follows the curvature of the surface 25. The member 23 may be mounted on a pair of arms 15 movable about pivots 18 on the power plant to raise the member 23 into its operative position, Figs. 7 and 13, by hydraulic jacks 20. The surface 25 may be smoothed into the walls 26, 27 to conform to the shape of the nozzle outlet, and may be of decreasing curvature from a point 25a to a discontinuity 25b to provide a breakaway point for the jet, the member 23 being rotatable about a pivot 24 to vary the direction of the jet, by either an hydraulic jack 28, or an electric motor 35. The member 23 may have a shroud 32, Fig. 7, encircling the jet, and may have a trough-shaped member 1 spaced from the surface 25 by a small gap. The whole assembly may be rotatable about the axis of the power plant. In an alternative form the surface 25 is part cylindrical with respect to the axis 24, and comprises two parts, one fixed and the other rotatable about the axis 24 and slidable under the fixed part, Figs. 8 to 10 (not shown).

Abstract: 1330193 Boots &c H MAGIDSON 19 Oct 1971 [29 June 1971] 48656/71 Heading A3B An insole consists of upper and lower layers of flexible non-porous plastics material having at least one fluid filled cavity formed between them which cushions and supports the wearer's foot and a covering of moisture-absorbing fabric disposed on the top surface of the upper layer. The plastics material may be polyethylene, vinyl or elastomeric plastics material and the fluid is non-compressible e.g. water or a gel. In a first embodiment (Fig. 3) a full insole adapted for insertion into a conventional shoe consists of a flat upper layer 10 and a shaped lower layer 12 which is sealed to upper layer 10 to form cavities 14a to d filled with fluid 14'. The walls 13a to d of the cavities are angled so that they do not provide local support for the foot. The upper layer 10 has a covering 16 of moisture absorbing fabric e.g. cotton. In a second embodiment (Fig. 4) the insole is built into the shoe 30 and consists of an upper layer 32 and lower layer 34. Cavities 36a, b and d are formed by shaped regions 34a, b and d in the lower layer 34 and cavity 36c is formed by raised region 32c in the upper layer 32 which forms an arch support. The pressure of the fluid in the cavity 32c may be greater than the pressure in the other cavities. In a modification (not shown) the inner sole of the shoe is formed with ribs and is sealed to an upper layer to form the insole, the internal cavities being defined by the ribs. The insole, may also be formed as a partial insole (not shown) having a single fluid filled cavity which is arranged to support the ball, arch or heel of the foot.

A mobile mixer for bituminous material has a bucket elevator 11 which can be swung about pivot 15 to rest on separate bogeys for transport, a lower mixer part 1 fixed to the wheeled chassis 8, an intermediate p a r t 2  pivotable about a horizontal axis to rest inverted on the chassis and an upper part 3 pivotable about a second horizontal axis 4, as the part 2 is moved, to rest on a second set of bogeys for transport. The elevator 11 is swung about pivots 15 by radial tipping arms 5 and links 10 to rest on two bogeys, in which condition the pivots 15 are unlatched. The hydraulically actuated arms 5 are connected to pivots 2a to swing the intermediate and upper parts 2, 3 about links 9. As the part 2 approaches the vertical rollers 7 on the upper part engage the sloping end of the chassis 8 to pivot the parts 2 and 3 relatively about the axis 4. Continued movement of the arms 5 allow the rollers 7 to engage a sloping surfaced separate bogey and pivotting continues until the upper part can be supported on two separate bogeys for individual transport and the intermediate part 2 rests inverted on the chassis 8. Hydraulically operated jacking legs are provided for the chassis when in working condition. Reference has been directed by the Comptroller to Specification 935,849.

Abstract: 1,243,367. Two part couplings. BELLING & LEE Ltd. 16 Oct., 1969 [16 Oct., 1968], No. 48974/68. Heading H2E. An electrical connector has a portion 3 (Fig. 1) provided with a number of insulating projecting portions 10, 11, 12, 13 having each a longitudinal recess of cruciform cross-section to accommodate a contact member 14, 15, 16 or 17 and to receive a contact member 30 of a co-operating connector portion 20, at least one of the insulating projecting portions being of generally prismatic cross-section. The co-operating connector portion 20 is provided with recesses 23 adapted to receive the projecting portions which are spaced, orientated or arranged to prevent incorrect insertion. This may be done by inserting keys 42 into longitudinal grooves 41 formed in the projections and recesses (Figs. 6 and 7) or by arranging the types of contact such that incorrect mating of a plug with another socket causes the ends of the contacts to abut, so preventing insertion. The provision of several holes in the cable retaining strip 33 enables different sized cables to be accommodated. The contact members 71 (Figs. 15 and 16) may be cranked at 78 so that space between adjacent terminals may be increased.

Abstract: 1479626 Suction cleaners HOOVER Ltd 13 Nov 1974 [16 Nov 1973] 49133/74 Heading A4F A suction cleaner body 10 is provided with a conversion valve 24 comprising a valve-member 26 movable by manually operable means, e.g. a rotatable dial 12, between positions for flow and off-the-flow suction respectively, a tool hose coupling 22 connectible to the body 10, and blocking means movable with the manually operable means and/or the valve-member 26 to prevent disconnection of the hose coupling. The valve member 26 is rotatable to connect a duct leading to a suction unit, either to a duct 32 leading to a flow engaging nozzle or to a duct 30 having an inlet 20 receiving the hose coupling 22 with a bayonet type connection. Lugs 70 on the coupling 22 are inserted into slots 72 in the inlet 20 and the coupling 22 rotated clockwise, as seen in Fig. 1, to latch it in position. When the dial 12 is set to the "tool suction" position, an eccentric flange 14 rotatable therewith is positioned to obstruct a tab 80 on the coupling 22 to prevent anti-clockwise rotation of the latter and its release. Rotation of the dial 12 to the "carpet suction" position removes the flange 14 from its obstructing position. In two further embodiments release of the coupling is prevented by the engagement of a lug (80 ) Fig. 10 or 12 (not shown) thereon behind the blocking flange (14') which is either eccentric to the dial, (Fig. 12) or provided with a notch (84, Fig. 10) for passage of the lug (80') when the dial is in the "carpet suction" position.
