As shown in Figs. 1 and 2, jet pipe 12 consists of an outer wall 16 and an inner wall 18 which is a sandwich structure composed of a perforate inner skin 20, a honeycomb member 24, and an outer skin 26 composed of a plurality of separate plates 26a. all these parts being of metal and welded together. In the modification shown in Fig. 4, the inner skin is composed of overlapping separate plates 20a and the outer skin is continuous. Where the separate plates do not overlap, as in Fig. 2, resilient U-shaped straps may be secured between them to seal the gaps between them (Fig. 5, not shown).

The winding and setting knob 12 of a watch is sealingly engaged over a sleeve 5 fixed to the case 1 and has three pins 14 passing through holes in a collar 6 fast with the stem 2. The pins are fixed to a ring 15 which in the position shown bears tightly on a resilient seal 10 to immobilize the knob. The knob is retained in this position by a spring ring 11 engaging a recess in collar 6 and notches in the pins 14. An additional seal 17 seals the outside of sleeve 5. The knob can be withdrawn to relax the seal and permit winding. A further pull on the knob moves the stem to handsetting position. In a second embodiment, Fig. 3 (not shown) collar (6) is extended outside the sleeve (5) to form a gripping portion and carries the seal (17). In Fig.4 (not shown) a ring (28) of inverted U-section is retained in knob (27) and engages the inner seal (26), knob (27) along with ring (28) can be withdrawn against a spring ring (31) located in a part (23) fixed to the stem. Part (23) has ears (24) in a recess (30) in the knob allowing relative axial movement. In the inner position of the knob, teeth (34) thereon engage teeth (35) on sleeve (4) to prevent rotation. In Fig. 6 (not shown) a seal (42) is compressed by a ring (41) in the inner position. In Fig 8 (not shown) an annular member 52 compresses the inner seal (55).

Abstract: 1451160 Etching INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1974 [26 Dec 1973] 51740/74 Heading B6J [Also in Division H1] In a method of etching apertures through an insulating layer 11 (e.g. silicon dioxide) on a semi-conductor substrate 10 the layer is provided with a first photomask defining apertures 20 and 21 and the layer etched so that in relatively thin areas thereof etching proceeds right through the layer (e.g. region 20) whilst in relatively thick areas thereof etching only partially penetrates the layer (e.g. region 21). The first photomask is then removed and a second photomask 23, Fig. 1D, applied so as to provide apertures 25 having the same lateral dimensions as incompletely etched openings 21 and to provide apertures 24 having smaller lateral dimensions than those of the completely etched openings 20 thereby protecting the side walls of the completely etched openings. A second etching step completes the etching of openings 21 and any openings 20 which (due to faults in the first masking and etching steps) was not previously etched through. Lateral etching during the second etching step ensures that any openings 21 which were not completed in the first etching step, reach the required lateral dimensions in spite of the presence of lesser lateral dimensions in the photomask openings at these areas. The etchant may comprise hydrofluoric acid and ammonium hydrofluoride.

A method of forming a pneumatic tyre comprises forming at least one fabric ply into a cylindrical band upon a radially-expansible tyre-building drum, locating bead rings around the band adjacent to its edges, and expanding that part of the band between the bead rings so that it is turned outwardly over the bead rings to contact and adhere to those parts of the band located outside the bead rings. As shown, the tyre-building drum comprises a radially-expansible cover 3 mounted on drum ends 2. Axially-displaceable and rotatable slide members 5, each bearing a segment 7 supported on an inflatable member 6, are located adjacent to the drum ends. To form a tyre blank a cylindrical band is formed on the drum, bead rings 11 are located adjacent the edges of the band, inflatable members 6 are inflated to bring the edges 10 of the band above and to the side of the bead rings, and the drum is inflated such that the central part 12 of the band is brought into contact with the edges 10 of the band. An axially-slidable tubular ring 18 may be used to assist in the contacting of part 12 with edges 10. Additional inflatable members 9 may be provided on segments 7.

Abstract: 1,149,053. Electrostatic precipitators. LODGE-COTTERELL Ltd. 1 Dec., 1966 [14 Dec., 1965], No. 52989/65. Heading B2J. A rapping device for an electrostatic precipitator is mounted on an endless conveyor which moves the device successively and continuously past rapping points 44, Fig. 3, on the precipitator. The precipitator casing 12, Fig. 1, comprises three groups of discharge electrodes 32 and three groups of collector electrode plates 28, each plate having a rapping point 44 and being suspended from a rod 30 supported by tension rods 31 which are suspended from the roof 20 of the precipitator casing 12. The rapping apparatus 21 comprises three mechanisms 40, each comprising a rectangular framework 52 extending along the roof 20 at right angles to its associated group of plates 28 and an endless motor-driven chain conveyor carrying rapping devices 42, Fig. 3. In operation, as a device 42 approaches a spring-loaded beam 46 which lies in the plane of an associated plate 28 to form a rapping point 44, a cam roll 76 on a bell crank lever 72 moves up a surface 80 of a guide 47 to raise pivoted rapping hammers 74 which are keyed to a shaft 70 together with the lever 72 until the roll falls over the edge 82 of the guide 47. The hammers then rap the beam 46. The three rapping mechanisms are arranged so that the speed of rapping of the left hand (Fig. 1) group of plates 28 is greatest and that of the right hand group least, either by providing different numbers of rapping devices or by having different chain speeds. By not rapping each group of plates 28 simultaneously excessive local re-entrainment of dust in the gas is prevented.

Abstract: 1283729 Feeding sheets GRAPHA MASCHINENFABRIK HANS MULLER AG 31 Oct 1969 [11 Nov 1968 18 Sept 1969] 53481/69 Heading B8R In apparatus for stacking paper sheets, including folded sheets such as pamphlets, the sheets 11 are individually fed by endless belts (5, 6), Fig. 2 (not shown), to cylindrical slotted members 4 which rotate to deliver each sheet so that a stack 19 is formed on the arms 18 of two sets of rotatably mounted star wheels 13. When the stack contains a predetermined number of sheets the star wheels 13 are rotated through 120 degrees, thus allowing the stack 19 to drop on to a table 20 mounted for rotation on a shaft 21. Thus, if the sheets 11 are folded sheets, and a uniform final package is required, each stack 19 can be stacked on the table 20 at a 180 degrees offset to the adjacent stack. The counting of the sheets 11 in the stacks 19 and of the stacks 19 on the table 20 is effected by photo-cells (90), (94) and the way in which these co-operate with a control and drive arrangement to effect the desired rotation of star wheels 13 and indexing of table 20 is described with reference to Figs. 2 to 6 (not shown). When the stacks on table 20 have reached the desired height a pusher 24 is actuated to eject the stacks on to a discharge conveyer. In a modification (Figs. 7 and 8, not shown) the stacking members 4 and star wheels 13 are replaced by rake-like fingers which can pivot away from a stack formed thereon, thereby allowing the stack to drop freely.
