Title: Methods of filling flexible containers
IPC: B65B1/26
Filed: 1970-05-11
Abstract: 1312705 A pressure-differential method of filling flexible containers with finely-divided material CLARENCE WEDEKIND VOGT 11 May 1970 [9 May 1969] 22611/70 Heading B8C In a method of filling flexible containers with a finely-divided material wherein occluded gases are substantially removed, a flexible paperboard carton 30 is lifted into sealing engagement with the lower end of a differential pressure-type filler 5 which has upper and lower valves 48, 14 open and closed respectively by valves 1, 3, while material is fed from a hopper 9 into a magazine 7, and closed and open respectively when the magazine is full, pressure then being applied, by means of a valve 2, and by way of an annular space 41 and a foraminous partition 38, to the material in the magazine as it flows downwardly into the carton 30 which, during this first filling phase, is thus maintained under slight pressure to prevent its collapse. Shortly after the valve 48 has been closed a vacuum source 28 is applied, through a valve 4 and an annular passage 24, to the upper end of the carton 30 to assist the flow of material from the magazine 7 and remove entrapped gases therefrom, the configuration of the carton 30 being maintained until flaps 18 on the lower end of the valve 14 are closed by the rising material. Valves 2, 3 are then operated to connect, respectively, the annular space 41 to atmosphere and close the valve 14. The valve 48 is then moved to its open position by connecting the valve 1 to a vacuum source 56 so that the magazine 7 is again charged with material, valve 4 being subsequently operated to vent the carton 30 to atmosphere or, to supply a low pressure to clean a filter 25 in the outlet of the annular passage 24. The carton 5 is then removed from engagement with sealing rings 33, 34, which may be pneumatic, and then closed. The vacuum source 28 should be of the order of 15-18 inches of mercury and the pressure source should be within the range of 15-20 p.s.i. above atmospheric pressure. The valves 1-4 are actuated by switches (S1- S4), Fig. 2 (not shown), which are controlled in sequence, respectively, by cams (C1-C4).

Title: Improvements in retractable landing gears for aircraft
IPC: B64C25/14
Filed: 1954-08-05
Abstract: 756,111. Aircraft undercarriages. MORANE-SAULNIER. Aug. 5, 1954 [Aug. 11, 1953]. No. 22802/54. Class 4. A retractable and steerable undercarriage for aircraft comprises a supporting member 5 which carries bearings 6, 7 for the rotatable mounting of a strut 4 formed with an offset pivot 3 for a wheel-carrying lever 2 in turn formed with a lug 19 for the pivotal connection of the lower end of a shock absorber 18 which is pivotally mounted at its upper end 20 in the strut 4. The member 5 carries laterally projecting arms terminating in bosses 12, 13 which are pivotally mounted on the aircraft structure and a fixed shaft 29. This shaft carries a sleeve 27 capable of axial and rotary movement and formed on its outer surface with teeth 26 which lie in planes normal to the axis of the sleeve and extend round half of its circumference. The sleeve carries a lug 39 connected by a link 38 to a bell-crank 34-35 to which a control rod 33 is connected, whereby movement of the rod 33 by the pilot causes axial movement of the sleeve 27. The strut 4 carries an upward projection formed with serrations that engage internal serrations on an annular collar 8 and this in turn carries external serrations engaging internal serrations 24 on a further annular collar 23 which, on its skirt, is formed with teeth 25 to mesh with the teeth 26 on sleeve 27. The teeth 25 are urged into engagement with the teeth 26 by a spring 46 acting on the collar 23 which, on opposed parts of its skirt clear of the teeth 25, is formed with two cam surfaces engaging fixed rollers. The undercarriage is retracted about the axis Y-Y by a jack (not shown) connected at 16 to a lug 17 on the member 5 and during retraction the teeth 25 on collar 23 remain in mesh with the teeth 26 on sleeve 27. When the undercarriage is lowered, steering is effected by manual or servo operation of the rod 33 which causes the strut 4 to rotate within the member 5. If the undercarriage tends to caster through an angle greater than the maximum angular deflection of the steering mechanism, the cam surfaces on the collar 23 engage the fixed rollers to raise the collar against the spring 46, thereby disengaging the teeth 25 from the teeth 26.

Title: Improvements in floating bridge construction
IPC: E01D15/14
Filed: 1944-11-18
Abstract: 584,768. Pontoon bridges. MAUNSELL, G. A. Nov. 18, 1944, No. 22934. [Class 20 (i)] [Also in Group XXXIII] A floating bridge comprises 'a number of pontoons placed end to end, axially connected by ball and socket joints, tightly bound together longitudinally by tensioned cables, and secured transversely by ground moorings. The terminal pontoons are connected to the shore by hinged girder spans, one of which is shown at A in Fig. 4. The shore end is carried on a roller' carriage F hauled back by ropes attached to a weight L, so maintaining a constant tension in the train of pontoons. A long expansion joint is provided at E. The pontoons designated P, Q --- V, are arranged to have their greatest width on their normal waterline for lateral stability, have a streamline cross-sectional contour underneath to reduce resistance to cross-currents, and low freeboard together with a deck hog-backed transversely to facilitate the overspill of wave crests. They are provided at one end with a knob K and at the other with a socket C into which the knob of the adjoining pontoon fits, and are held firmly together by the tensioned cables H. The roadway D is elevated to be clear from waves washing over the decks of the pontoons. The short junctions of roadway J between adjacent pontoons are articulated to conform to the relative movements of the pontoons. One or more pontoons are submersible to provide a channel for shipping, the submersion being effected by flooding a centrally dispersed chamber in the pontoon of such a size that when completely filled the whole pontoon just loses buoyancy. Excessive submersion is prevented by stools on the sea bed on which the pontoons rest or suspended weights O which on touching the bottom arrest the submersion of the pontoon. The ball and socket joints and shore arrangement of the girder spans allow the submersion without disconnecting any of the pontoons. The submerged pontoons are raised by expelling the flooding water with compressed air. The submersible pontoons are arranged to have their centre of gravity below the centre of buoyancy when submerged, for stability. All the pontoons have fenders N and the moorings are designed to drag before the mooring cables would break to minimise damage in the case of collision with a ship. Suitable dimensions of pontoons for a mile long crossing are given as length 500ft., beam 60ft., and displacement 6,000 tons.
