Title: Improvements in and relating to roll-up lattice shutters or grilles
IPC: E06B9/18
Filed: 1922-04-24
Abstract: 193,323. Gibson, W. P. April 24, 1922. Trellis and lattice work.-Lattice roller shutters such as are used for protecting shop-windows doors &c. are built up from a number of similar units each of which may be detached and replaced separately. Fig. 1 sloows triangular metal stampings strengthened by twisted portions b and having hooks 40 at one corner and openings 42 at remaining corners for connection as shown. The edges of the shutter which run in guides 44 are formed by pairs of members 43, 48 having plates 44<a>, 49, to prevent withdrawal from the guides. The hooks 40 may be disengaged by inclining the members as shown, in Fig. 3. Square &c. members having two hooks and two eyes may be joined as shown in Fig. 13, suitable side guiding members being provided. The members may be joined by means of a T-shaped slotted piece passing through the eyes and engaged by the hooks. In a modification shown in Fig. 16, the members are cast and have arms and lugs 61, 62, and separated hooks 63. These members are joined by inclining the lugs so that they pass through the hook openings and swinging the members into the same plane when the lugs reach the gaps between the pairs of hooks. A member 65 having a curved guiding rib is provided to complete the side. The bottom or end row is secured by clamping their straightened out hooks to a bar. In another form of lattice composed of triangular elements, two of the eyes of each element are slotted and are engaged with the remaining eye of another element by tilting.

Abstract: 459,691. Aeroplane wing mounting. BAYNES, L. E., 144, Cromwell Road, South Kensington, London, and ABBOTT, Ltd., E. D., Farnham, Surrey. April 22, 1936, No. 11492. [Class 4] In an aeroplane having a single spar wing of variable incidence, the wing is of cantilever construction supported by pivots at the apices of two outrigger structures extending laterally and upwardly from opposite sides of the fuselage. An aeroplane, Fig. 2. of the 'Mignet ' type has a forward wing 5 adapted to be rocked about a transverse axis A-A lying adjacent to and parallel to the line of its mean centre of pressure. Control may be effected by means such as described in Specification 458,751. Wing 5 is pivotally supported at spaced points. 9 by outrigger structures comprising struts disposed in a plane transverse to the plane of symmetry and secured to lugs carried by the lower longerons of the fuselage and struts 12 attached to lugs carried by the upper longerons of the fuselage and respectively forwardly and rearwardly inclined. Struts 10, 12 are united at their upper ends by a fitting 13 formed with vertical spaced ears 15, Fig. 4, adapted to form the lower member of the pivot about which the wing rocks. The upper pivot member consists of trunnions 16, 17 of which the axes are mutually at right angles united by a web 18. Trunnion 16 is pivoted between ears 15 and trunnion 17 is positioned between ears 20 formed on plates 21 bolted on opposite sides of wing spar 22 and is secured by a quickwithdrawal pin 23.

Abstract: 1,033,946. Vehicle coupling and uncoupling devices. STAMICARBON N.V. March 22, 1963 [March 23, 19621, No. 11526/63. Heading B7T. A trackside automatic coupling and uncoupling apparatus such as that shown in Specification 926,439, for hook and link rail vehicle couplings, may have its hook engaging magnetic arm replaced by the arm now to be described. A lever 7, Figs. 1, 4 pivoted at 8 to a plate 1, carries an adjustable tooth 9 and is connected by a piston-rod 6 to a pressure cylinder 4 pivoted at 5. By swinging the shaft 3 downwardly or by moving the shaft axially the jaws may be inserted from the trackside into a position between two vehicles, and by then actuating the cylinder 4 the tooth 9 may be swung towards a fixed but adjustable tooth 10 so as to pivotally clamp a coupling hook 13 therebetween at a point 14, Fig. 5. The plate I is provided with a stop plate 12 which ensures that the teeth 9, 10 engage the hook at substantially the same point 14 every time. The plate 1 and the engaged hook may then be swung in a vertical plane for coupling or uncoupling by rotation of the shaft 3. Without its power cylinder 4 the jaws may be adapted for manual control through a hand lever, and both teeth may be arranged to move. The tooth 9 may however be mounted for linear movement.

Abstract: 1,140,452. Rotary vacuum-pumps. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. March 10, 1967 [March 16, 19661, No.11533/66. Heading F1F. In a rotary vacuum-pump of the outwardlysliding radial-vane type, noise generated by compression of sealing liquid e.g. oil, 8, Fig. 1, in and adjacent to an outlet duct 7 is suppressed by a ring 10 that is lodged in the wall of said duct and made of resilient pressure-energy absorbing material, e.g. foamed rubber or synthetic plastics material. The duct 7 is controlled by a valve comprising a flexible flap 5 that is clamped against the body 1 of the pump by a rigid plate 6 and made of either a synthetic plastics material or an elastomeric one; and, alternatively, said noise may be suppressed by air in a closed pocket (11), Fig. 2 (not shown), which is formed within said flap in register with said duct, the ring 10 being dispensed with. In another embodiment, Fig. 3, the noise aforesaid is suppresed by air within a recess 13 that is formed in the plate 6 in alignment with a similar recess within the body of the pump, the latter recess being separated from the former one by the flap 5 and connected to the duct 7 by a passage 14. Atmospheric air enters the recess 13 through a pipe 15. In each embodiment, the pump is sealed by being immersed in oil 2.

Title: A liquid-cooled continuous casting mould
IPC: B22D11/05
Filed: 1969-03-04
Abstract: 1,267,592. Continuous casting. MANNESMANN A.G. 4 March, 1969 [19 March, 1968], No. 11550/69. Heading B3F. In a mould supported on a frame 6, Fig. 2, and formed of water-cooled plates 1-4 (held together by bolts 5), two opposed plates 3, 4 each comprise two wedge-shaped units 14, 15, so that relative up-and-down movement, e.g., by means of a screw-threaded spindle 17, Fig. 4, and nuts 21, 22, while the bolts 5 are temporarily loosened, widens these sides and broadens the mould cavity, which may have a curved axis. The spindle 17 is located in a bore 16 in one wall unit 14 of a narrow wall 3 or 4 and held from axial movement by a ring portion 18 at its middle, located in a recess (19) at the end of a projection from a backing support 13 for the wall units 14, 15. It has threads of opposed bands so that its rotation causes the nuts 21, 22 to move in opposite directions. Spigots 23, 24 from the nuts cause similar movement of the units 14, 15 since there are slotted holes 29 to receive bolts 25-28 by which the narrow wall 3 or 4 is held on the backing support 13. This support is in two parts 13a, 13b, Fig. 3, between which lie transverse bolts, 30, 31 bearing conical nuts 32, 33 which can spread the parts 13a, 13b to tighten the bolts 25-28. By means of screw-threaded spindles 11 (12) and worm gearing 8, 9, Fig. 3, of drives 7, the narrow walls 3, 4 are also movable towards and away from each other so as to widen or narrow the mould cavity and, since the lower spindles (12) have a smaller pitch, the angle between the narrow walls 3, 4 is changed to modify the cavity taper at the same time. The mould may be divided into two cavities by a wall (34), between the narrow walls 3, 4 and comprising backing parts (13a, 13b) with a pair of units (14, 15 at) each side.
