Title: Signal horn for motor vehicles
IPC: G10K9/13
Filed: 1972-10-20
Abstract: 1373869 Electric horns ROBERT BOSCH GmbH 20 Oct 1972 [23 Oct 1971] 48454/72 Heading G5J An electromagnetic horn for motor vehicles has a cup-shaped circular sheet metal housing 12, which centrally carries a fixed core member 14, for an electromagnet coil 19, and the coil former 18 surrounding the core is fastened by an operation of local deformation applied at points 20, 21, 22, to the core 14. The coil former 18 has an internal shoulder 25, between portions of differing diameters, 17<SP>1</SP> and 17<SP>11</SP> of the bore 17, and the operation of deformation causes material from the core face 26 to become displaced locally, into position 24, Fig. 3, against the shoulder 25. The core 14 may be composed of solid soft iron material, or of laminated material. The coil former bore is an interference fit on the core, before deformation.

Title: Textile combers
IPC: D01G19/22
Filed: 1970-10-13
Abstract: 1332359 Carding machines NITTO SHOJI KK and A MORIWAKI 13 Out 1970 [22 Oct 1969] 48480/70 Heading D1N In a carding or combing machine a pair of nip rollers 1a, 1b feed fibre to a comb cylinder 2 which carries it to a divider roller 4. The divider roller 4 is faced with alternate slots 29, containing saw-toothed members, and solid portions 30 whose circumferential length is L. Transfer of fibre is aided by suction applied within rollers 2 and 4. If it is desired to remove fibres of length l from the fibre mass it is stated that the surface speeds of the rollers 2 and 4, V 2  and V 4  respectively, should be related thus: The rate of fibre transfer is controlled by varying the clearance of a guide plate 6 with the rollers 2 and 4. Fibres are removed from the divider roller 4 by a detachment roller 8 from which it is doffed by a doffer roller 11. Suction is applied to rollers 2, 4, 8 and 11 through radial slots or pores in their cylindrical shell 21, Fig. 4B, via an internal cavity 23 and conduit 24. Rollers 2, 4 and 8 are clothed with saw toothed wire, see Figs. 2, 3, 5 and 7 (not shown) and nip rollers 1a and 1b are saw toothed fluted, rubber or apron type. Brush rollers 3, 7 and 9 are provided for cleaning purposes and the machine is enclosed by casings 12, 13 and 14 and has an inner partition 16. A single comb cylinder 2 may cooperate with more than one divider roller as is illustrated in Fig. 9 (not shown). In this arrangement the fibre is recycled to the comb cylinder (2) after each divider roller and finally removed by a detachment roller (8).

Title: Improvements in or relating to electron discharge tubes

Abstract: 1,263,585. Discharge tubes. SIEMENS A.G. 2 Oct., 1969 [3 Oct., 1968], No. 48507/69. Heading H1D. In a method of assembling together a plurality of electrodes each having a substantially planar portion and all the planar portions being parallel to one another in the completed assembly, the electrodes are first axially aligned by means of a jig, the relative spacings between the electrodes are then determined by interposed sections of ceramic tube with respect to which the electrodes initially have limited freedom of movement parallel to their planar portions, and the electrodes are subsequently fixed in their aligned positions by means of a settable material which flows in the unset state into gaps between the electrodes and the sections of tube. In assembling the gun electrodes of a travelling- wave tube, diaphragm electrodes 1 and 1<SP>1</SP> each having three 120-degree spaced holes 2, 2<SP>1</SP> arranged around its edge (only one shown), are first aligned by mounting them by their central apertures upon the jig 3. Aluminium ceramic tubes 5, 6, 7, 8 are then mounted around each set of holes 2, 2<SP>1</SP> and are clamped together by a molybdenum pin 9 sheathed by a protective ceramic tube 4 and secured under tension by a rivet or nut 13, whereby tubes 6 and 7 fix the spacing between the two electrodes at the desired value, the relative expansion coefficient of the materials of pin 9 and tubes 5, 6, 7, 8 being such that the tension in pin 9 is maintained upon rise of temperature. To ensure retention of the electrodes in the aligned position determined by jig 3 and to take up any inaccuracy 14 in the end faces of the ceramic tubes, a filler material 11, 12-such as heated platinum, or a thixotropic material containing aluminium oxide or beryllium oxide-is introduced between the electrodes and the tube 4, and at the ends of pin 9, whereafter the assembly is removed from jig 3. Preferably a surface gap of slight thicknesse.g. 10 microns-is provided between tubes 6 and 7, either by slight elevations on their opposed end faces, or-as shown-by the interposition of metal foil 10, in order to prevent the formation, in operation of the tube, of a conductive path between the electrodes by metallic vapour deposition.

The lever 5 pivots about a rivet 7 on a laterally moveable plate 6, so that during moving contact between 3a, 10 the lever 5 rotates the ring 12 and closes the diaphragm to its pre-selected aperture, entry of the follower 10 into the portion 36 allowing the mechanism 1, 3 to operate the shutter release. The extent to which the diaphragm is closed, i.e. the selection of the aperture, is determined by adjusting the lateral position of the plate 6 by means of the ring 17 and bell-crank 16. In a modification, Fig. 3 (not shown) pre-selection is by axial movement of the diaphragmactuating lever (36) which has a pin and slot connection with an intermediate lever (35a, 36b) which carries the cam follower (35c). In a further modification, Fig. 4 (not shown) operation of the actuating lever (51) is through a cam cylinder (46) and pre-selection is by axial adjustment of the cylinder.

Abstract: 1,163,849. Making metal strip. CONTIMET G.m.b.H. 3 Nov., 1967 [9 Nov., 1966], No. 50150/67. Heading B3A. [Also in Division C7] Titanium strip, in commercially pure form in either alpha stabilized alpha type or alpha stabilized alpha-beta type alloy, is produced by; hot rolling the metal at an initial temperature to ensure that the reduction is largely within the alpha-beta field; heating the resulting strip above the beta transus to transform the metal to beta phase rapidly cooling the strip to a temperature below the beta transus to produce an acicular structure; and rolling and annealing the strip to give a completely recrystallized structure. In an example a 5% Al, 2.5% Sn, balance Ti, alloy having a beta transus of 1900 F.  25 F. was hot rolled from 2100 F. to give a strip of 0.135 inch thickness. After heating for 3 mins. at 1950 F., water quenching followed to give an acicular structure. Cycles of 15% reduction at room temperature, each followed by line annealing for 5 mins. at 1600 F., produced the desired recrystallization. Similar examples, differing mainly in rolling reductions and annealing conditions, are described for alloys of 8% Al, 1% M, 1% Va, balance Ti, and 6% Al, 4% V, balance Ti.
