Abstract: 912,610. Wall &c. linings; panels; joining metal sheets. DOBLE, M. S. Dec. 3, 1958 [Sept. 4, 1957], No. 27909/57. Classes 20 (2), 20 (4) and 87 (1). [Also in Group XXV] In a device for connecting two parts 40, 45, each part, which as shown, is a strip, is provided with a tongue 41 or 46 of relatively stiff sheet material so that the tongue of one part is slidable under the tongue of the other part and the tongue of one part comprises a protrusion 53 on the face engageable with the other tongue, which latter accommodates the protrusion when the parts are in the fully engaged position, the protrusion 53 operating to flex the tongues apart at the initial part of the sliding movement to engage the tongues and operating to resist sliding apart of the tongues once they are in full engagement. The tongues are offset from the planes of their respective strip and extend parallel thereto. In another arrangement, Fig. 3 (not shown), the tongues are formed respectively with co-operating ribs and steps to provide a snap connection between the strips. In the arrangement according to Fig. 4, a sheet 60 is provided on one edge with cuts 61 defining tongues 62 joggled to one side of the sheet and with alternate tongues 64 joggled to the other side of the sheet. The tongues 62 are formed with ribs 66. Another sheet 70 is provided with similar tongues 72 and 74, the arrangement being such that the ribbed tongues of the sheet are joggled towards the same side of the sheets as the plain tongues of the other sheet, whereby when the tongued edges are interengaged the tongues 72 engage one side of the tongues 62 and the tongues 64 engage on the other side of the tongues 74, the ribs 66 forming a releasable snap joint. According to Figs. 9 to 11 (not shown) the strips are secured to opposite ends of panels and to a plurality of purlins to receive the panels to form a wall. In the arrangement according to Figs. 12-14 (not shown), a panel comprises a facing secured to a frame to the upper and lower side members of which are secured strips with tongues thereof pointing to opposite directions. A number of such panels is arranged to form a wall, Fig. 15 (not shown). In another arrangement. Figs. 16-18 (not shown), a panel is formed at its edges with flanges which are provided with tongues and apertures by which a number of the panels may be secured together to form a wall, Fig. 19 (not shown). In another form, Fig. 20 (not shown), each panel is provided at opposite edges with extensions and joggled tongues and is provided at its other opposite edges with tongues of the form described with reference to Fig. 4. In a modification of the Fig. 1 arrangement, Fig. 21 (not shown) the tongues are dimensionally identical.

Title: Improvements in or relating to loud speaking telephones
IPC: H04R9/04
Filed: 1925-11-10
Abstract: 256,443. Clarke, G. T. S. Nov. 10, 1925. Magnetic instruments; loud-speakers; diaphragms.-Relates to loud-speaking telephones of the kind in which a movable coil attached to a relatively large diaphragm is located in an annular gap between concentric, magnet coils. According to the invention, the coil is centred and guided by an axially arranged pin or rod, carried by one of the relatively movable parts, viz., the coil or the magnet, and adapted to slide in an axial hole or equivalent guiding device in the other relatively fixed or movable part. In the constructions shown in Figs. 1 and 2, the coil 5 is wound upon a light former 6 carried by a spider 7. 8 which is bolted to a conical diaphragm 9. The coil is disposed between magnet poles 2, 3, the pole 2 having an axial recess 13 in which is a bush 14 of rubber, felt &c. The bolt 10 which connects the spider to the diaphragm slidably engages the hole in the bush, which thereby centralizes and guides the coil, and exerts a slight damping action on the diaphragm. A vent 16 connects the recess 13 with the atmosphere. An additional guide is provided, in the construction shown in Fig. 2, by a stud 18, extending from the magnet pole 3 through the diaphragm and carrying an arm 17 having a bush 14<1> engaging with an extension of the bolt 10. In a further modification, two studs extend from the central magnet pole through a disc at the end of the coil carrying member 6 which member may be integral with the diaphragm. These studs lie on either side of the central pin 10, and support a bush which engages similarly to the bush 14<1>, with one end of the pin 10, the other end passing into a bush in the central magnet pole. Fig. 4 shows a loud-speaker to which the invention is applied. The diaphragm is supported by a flexible marginal ring 22, which is clamped by a metal ring 24 having a flange 25 spaced a small distance in front of the margin 22.

Title: Improvements in or relating to code translator arrangements
IPC: B07C3/00
Filed: 1965-07-05
Abstract: 1,064,216. Selective signalling. SIEMENS A.G. July 5, 1965 [July 4, 1964], No. 28308/65. Heading G4H. As one step in a letter sorting process an operator keys four letters (e.g. 1st, 3rd, 4th and last) taken from the destination town of the letter, which causes a corresponding combination of marks to be printed on the envelope for subsequent machine sensing and sorting. However, this process of selecting particular letters in destination towns may result in the same combination of letters being keyed for two or more different towns. The equipment provided by the invention, which is described in general terms only, detects such ambiguous combinations and by lighting a lamp indicates to the operator that he should key an additional letter (e.g. the 2nd) which in the encoding process replaces one of the letters already keyed, whereby the subsequent equipment still has to process only combinations of four letters.

Title: Target directed projectile
IPC: F42B10/34
Filed: 1972-06-16
Abstract: 1389950 Projectiles CANADA DEFENCE MINISTER OF 16 June 1972 [17 June 1971] 28421/72 Heading F3A A tubular projectile 10 which may be aerodynamically stabilized, spin stabilized, or stabilized by a combination of aerodynamic and spin forces, has its leading end 12 bevelled so as to releasably retain a front rider band 18 while its trailing end 14 is formed with a radially extending rib 20 rearwardly of which there is provided a seat 22. The seat 22 is fluted and has a diameter less than the outer diameter of the projectile 10. A pusher base 26 is releasably mounted on the trailing end 14, being formed with a seat 32 adapted to closely receive the trailing end 14. A driving band 34 is removably mounted partly on the circumference of the pusher base 26 and partly on the seat 22 of the projectile 10, and serves to hold the pusher base 26 in place during handling of the projectile. A rubber seal 36 secured to the outer face 30 of the pusher base 26 prevents gases from flowing past the projectile during launch. In a spin stabilized mode, the outer surface of the projectile is extended by the launcher riflings to produce the desired spin rate. Upon exit from the muzzle of the launch tube, the bands 18, 34 are separated and discarded by the large centifugal forces which have been built up. The pusher base 26 is subsequently pushed out of the back of the projectile, this being caused by the large stagnation pressure created by the normal shock wave ahead of the projectile. Once the projectile is in free flight, the flow of air is supersonic both internally and externally. In an aerodynamically stabilized mode, the bands 18, 34 are separated and discarded after launching by the combined effects of air friction drag and stagnation pressure generated by movement of the projectile in free flight.

Abstract: 1,167,476. Closures. M. B. STULL. 14 June, 1968 [12 July, 1967], No. 28560/68. Heading B8T. A reclosable dispensing cap assembly for containers having two sealed positions and an open position comprises a cap 14 of generally frusto-conical shape but with an oblique planar wall 18 having a dispensing orifice 28, mounted on a tubular body 10 communicating with the container. In the first, sealed position, Fig. 3, two seals are provided, one by an internal flange 34 engaging with the inner bore 24 of the body 10 and another by a part 30 of the tubular portion engaging in the orifice 28. On rotation from this position, a lug 38 on the cap rides up a camming surface 36 on the tubular body so that the cap moves axially until a bead 40 on the cap engages between two beads 42 and 44 on the tubular body, Fig. 8 (not shown). In this position, the orifice is open and the contents can be discharged, further rotation of the cap in an anticlockwise direction being prevented by a stop lug 48 on the body. Clockwise rotation causes a raised portion 46 on the body to engage in the orifice 28 to seal the package, axial movement of the cap being prevented by engagement of the beads 40, 42 and 44. In this way no product is forced from the orifice during reclosing, although if desired, the cap could be forced axially down to its original factory sealed position. Marks indicating the amount of rotation of the cap may be used to show how far the orifice is open, Fig. 4 (not shown).
