Abstract: 850,560. Road vehicle spring suspensions. COMPAGNIE GENERALE DES ETABLIS SEMENTS MICHELIN RAISON SOCIAL R. PUISEUX & CIE. Feb. 5, 1959 [Feb. 5, 1958], No. 4123/59. Classes 108(2) and 108(3). Leaf springs 2a, 2b, are disposed respectively above and below a vehicle axle 1 and are connected at their ends to the vehicle frame 4, the axle 1 being connected to the springs 2a, 2b, at spaced resilient connections 27, and also being supported from the frame 4 by a pneumatic spring 15, 16. The latter comprises a bellows 16 and a rigid reservoir 15. The supply of air to, and exhaust from, the spring is controlled by a levelling valve 31 mounted on the frame 4 and connected by a linkage 32, 21, to the axle 1. The axle 1 has limited lateral and longitudinal movement relative to a member 29 (which carries the connections 27 and supports the pneumatic spring 16) by virtue of the pair of rubber bush mountings 14, 14. Compression and rebound are limited respectively by resilient stops 20 and 23. The latter is adapted to engage an abutment 22 carried by the link 21. Each leaf spring 2a, 2b, is of constant thickness between the resilient connections 27, but its thickness decreases parabolically between each connection 27 and the associated connection to the frame 4. Over the latter portion of the spring, the width decreases progressively as shown in Fig. 7. In a modified construction (Figs. 1-4, not shown), the connections 27 are replaced in the case of each spring 2a, 2b, by rigid connections between the member 29 and the spring, these connections being relatively close together.

A broad band low reflection sound absorber comprises means for generating flow reversals normal to the direction of the incident sound in the medium of a transformation layer, the velocity head of the medium being attenuated by friction or other dissipative energy loss. The transformation layer may be formed by a film of liquid containing compressible occlusions, such as free gas bubbles, and covered with a relatively rigid skin. Alternatively, the compressible occlusions may be formed in an internal or external skin or lining of the absorber and be covered with foil. In further embodiments, a matrix containing a regular or random arrangement of liquid filled channels is provided, the occlusions being formed either in the channels or in the matrix. The channels may be in the form of shallow channels or incisions cut into an exposed face of the matrix. The absorber may also be made by securing pieces of closed cell foamed rubber to a wall coated with adhesive, embedding the pieces in a partially cross-linked plastics composition and then applying a coat of liquid-tight lacquer. A flexible backing sheet may be provided on the absorber to enable it to be provided in the form of " wall paper." Fibrous or flaky substances may be incorporated in the transformation layers to increase the dissipation of energy and the layer may be applied to the surface to be insulated by spraying or trowelling.

IPC: B66B21/12
Filed: 1968-01-26
Abstract: 1,216,102. Railway systems. W. K. CROWDER, and T. A. MURPHY. 26 Jan., 1968 [27 Jan., 1967], No. 4286/68. Heading B7L. [Also in Divisions B8 and H2] A travelator or like conveyer comprises a plurality of pivotally interconnected platforms 1, 1A guided by a pair of tracks 21, 54, the relative spacing of which varies along the conveying path to vary the speed of advance of the platform therealong. Each platform 1A has a fixed pin 13 which extends in pivotal arrangement through a platform 1 and mounts a pair of truncated core-shaped wheels 15, 17 for engagement with a correspondingly shaped track 21. A post 24 fixed to each platform 1 mounts similarly shaped wheels 15A, 17A for engagement with a track 54 and also mounts a wheel 23 to support an adjacent platform 1A. A further post 5 fixed to each platform 1 extends in pivotal relationship through an adjacent platform 1A and mounts a wheel 10 for engagement with drive rollers 25, 26. The rollers 25, 26 extend parallel to the conveying path and are driven at a constant speed by motors 50 and chain and sprocket arrangements 41, 51, 52. Where it is desired to alter the speed of the conveyer, suitable variation of the spacing of the tracks 21, 54 causes the platforms to pivot relative to each other, thereby altering the angle of the roller 10 with respect to the drive rollers 25, 26 and hence the helical advance thereof and thus the speed of the conveyer. The conveyer may be used in a pedestrian conveyance system which comprises a main loop extending between desired destinations and arranged at said destinations to reduce speed for the ingress and egress of passengers. Those passengers desiring to by-pass a particular destination transfer to a high speed loop 3 running at a similar speed to the main conveyer. In an alternative embodiment, Fig. 9 (not shown), the rollers (25), (26) are driven by a motor formed integral therewith. In a further embodiment, Fig. 13 (not shown), the platform equipped with shoes (46) which coact with linear motor stators (48) to drive said conveyer

Title: Improvements in the manufacture of tube bends
IPC: B21C37/28
Filed: 1963-02-04
Abstract: 973,133. Making tube bends; bending; forging. BABCOCK & WILCOX Ltd. Feb. 4, 1963 [Feb. 7, 1962], No. 4396/63. Headings B3A, B3E, B3H and B3Q. A method of making steel tube bends having a small radius of bend comprises forming a bend of large radius, heating the median part of the bend, holding the rectilineal branches by respective jaw members and giving the jaw members relative motion normal to the transverse plane of symmetry of the bend to effect a compression of the heated region which at least initially is free of contact with any surfaces of support or compression. A tube bend of relatively large radius is heated in the region ABCD and placed between two parallel plates 4, 6 each formed in two parts 4<SP>1</SP>, 4<SP>11</SP> and 6<SP>1</SP>, 6<SP>11</SP> positioned by bands 8 to leave a central free space 10. Rectilineal branches 2<SP>1</SP>, 2<SP>11</SP> of the bend are held by jaws 14, 16, each in two parts 14<SP>1</SP>, 14<SP>11</SP> and 16<SP>1</SP>, 16<SP>11</SP>, which are then moved towards one another in the direction G to deform the bend, thickening the inner and outer bend walls as shown in Fig. 3. A heated neutral gas under pressure may be passed into the tube towards the end of the compression to apply the soft parts of the outside of the bend to contours 24, 26 of the jaws 14, 16. The region ABCD may be heated by a ring of jets during compression. A rib may be formed on the bend between the upper parts 28, 30 of the jaws 14, 16. Grooves may be provided in the jaws 14, 16 to enable ribs to be formed by pressing metal in the grooves. In an alternative arrangement, Fig. 6, plates 4A, 6A are each in one part but are hollowed out at 22 so that the bend 2A may swell freely; bends of 120 degrees may be worked as above.

Abstract: 1,274,657. Battery terminal posts. JOSEPH LUCAS (INDUSTRIES) Ltd. 26 Sept., 1969 [11 Oct., 1968; 27 Jan., 1969], Nos. 48293/68 and 4418/69. Heading H1B. A secondary battery comprises a container divided into a plurality of cells, a lid, an assembly of plates and separators in each cell, connecting means joining adjacent cells in series, a pair of terminal posts, each extending upward from one of the terminal plate assemblies through a hole in the lid and a sleeve comprising upper and lower parts secured to each post where it passes through the hole in the lid, the parts being resistance-welded together to secure the sleeve to the lid. In a particular embodiment, the sleeve may comprise two hexagonal nuts 22 and 23 which grip a rib 24 extending round the inside of the hole. To improve the seal, each nut may be made integral with a sealing ring 28. Alternatively, each of the gripping surfaces of the nuts may be dished so that the nut is thicker at the outside than towards the centre or the sealing rings may be made integral with the upper and lower surfaces of the rib 24. The vertical edges of the rib 24 may have a horizontal groove of triangular cross-section (not shown) to facilitate resistancewelding. In setting up this arrangement, the two nuts are first placed on either side of the lid before it is joined to the battery container and a stainless steel former is inserted in the central hole. After resistance-welding the two nuts together, the former is removed and the lid placed on the battery, so that the terminal post fills the central hole. The terminal post may then be joined to the nuts by melting the top of it.

Title: Improvements in or relating to rotors for turbo-machines
IPC: F01D5/06
Filed: 1945-02-23
Abstract: 580,036. Turbine blades and rotors. STRUB, R. Feb. 23, 1945, No. 4583. Convention date, Feb. 25, 1944. [Class 110 (iii)] [Also in Group XXII] In a method of manufacture of turbine rotors the blades are welded together to form a rim and then welded to a rotor disc. Finally the discs are welded to each other and end pieces to form the complete rotor. The blades 2, Fig. 2, are fitted together to form a rim held against movement by the rings 3 of a holder and secured by bolts 4. The inner edge of each blade root 1 is tapered so that the interspaces 5, formed by assembly of the blades, form a groove for a weld seam 6. After welding the blade rim is internally machined ; the broken shading in Fig. 3 being the part removed forming a flat 7 and adjoining taper surfaces 8. These surfaces co-operate with surfaces 9, 11, Fig. 4, when the blades are mounted on a rotor disc to provide a weld seam 12. The double shaded portion is then removed by machining. In a modification the blades are welded on inter-spaces formed on the outside of the blade roots, which are then gripped on the inside by the holder to allow access for welding tools. Alternatively, welds may be made in inter-spaces formed on both the inside and outside of the rim formed by the blade roots. Further a pin may be fitted to the bottom of a weld to extend substantially across the width of the blade root ; in the case of double welds this pin is fitted between the weld seams. In another form a square pin 24, Fig. 11, fitted between the welds, has slots 25 to engage an easily deformed wire 26. The weld contracts on cooling, deforming the wire, and allows the pin to fit tight against the sides 27 of the groove in the blade roots. Alternatively the blade rim can be welded to a rotor disc which is drilled in the middle and keyed to a shaft; a solid rotor body, or a drum-shaped rotor body.

Abstract: 855,618. Moulding sheets, panels &c., from wood-resin compositions. KREIBAUM, O. Feb. 11, 1959 [Feb. 14, 1958], No. 4799/59. Class 87(2). Panels are pressed from wood chips and a thermosetting resin binding agent between vertical plates 6, 7 which effect the compression by horizontal movement. The compressed panel leaves the compression space downwards between rollers 10. The upper end 6a of the plate 6, where the material is fed, is shaped so that an enlargment 8 is made on the end of the panel which forms a support 8a for the next batch of material. The top is unheated during the compression and the binding material in the enlargement 8 remains unset ; consequently, when the material for the next pressing operation has been fed in, the part 8a unites readily with it as the panel is pressed. To compensate for the precompressing effect, on the material first fed, of the weight of the material subsequently fed, the press plates may initially open upwards at a slight angle, becoming parallel at the pressing operation and so exciting high compression on the material not precompressed. The material may be fed from three hoppers, one feeding craise chips into the middle and two feeding fine chips next to the plates. The compressed plate may be delivered from the press sideways. Plates with rounded edges and grooved surfaces may be produced. There may be a series of compression chambers between vertical plates.
