Title: Improvements in or relating to ferrite compositions
IPC: C04B35/26
Filed: 1959-05-14
Abstract: 866,295. Magnetic compositions. WESTERN ELECTRIC CO. Inc. May 14, 1959 [May 15, 1958], No. 16539/59. Drawings to Specification. Class 38 (2). The coercivity of a manganese-magnesium ferrite containing metals in the atom percentages Fe 55  to Fe 63  Mg 17  to Mg 25  Mn 12  to Mn 28  and having a rectangular hysteresis loop and high Curie' temperature, is reduced by replacing 5 to 8.5 atoms per cent of the metals by cadmium. The ingredients, in the form of carbonates, hydromides, oxalates or oxides, are mixed as a slurry in water, acetone, carbon tetrachloride or ethanol, dried and calcined at 800‹ to 1100‹ C. for 2 to 16 hours. The resulting material is ball-milled and mixed with a binder and lubricant (e.g. polyvinyl alcohol, " Opal Wax " or " Halowax "). After drying and granulating by forcing the solids through a screen, the particles are pressed into shape at 10,000 to 15,000 lb. per square inch pressure. The body is dewaxed for 6 hours at 400‹ C., after taking 6 hours in heating to this temperature, and is finally fired at 1250‹ C. to 1350‹ C. in an atmosphere containing oxygen, and cooled in nitrogen. A switching and memory device employing the material is referred to.

A filter plug is made by feeding simultaneously to a garniture 14 a sliver of wool 15, a strip 10 of stout paper, e.g. cartridge or parchment paper, that is formed into a tube having a longitudinal butt joint 10A and enclosing the wool, and a strip 22 of thin paper, e.g. cigarette paper, that is formed into an outer tube having a longitudinal lapped and stuck seam 22A. The strips 10, 22 may be fed from rolls 11, 23 through pre-folders 12, 24 which form the strips into U-section, and the wool fed from a roll 16 is compacted on a tape 17 by wheels 18, 19. Paste applied to one edge of strip 22 is dried by an electrically heated iron 28 when the lap joint is formed and a cutter 31 severs the continuous filter rod, which is pulled through the garniture by an endless belt 30, into lengths 29A which are conveyed to a packing or cigarette-making machine. The wool may be attached to strip 22 by adhesive applied by wheel 39.

Title: Improvements in or relating to electrically controlled railway signalling apparatus
IPC: B61L19/14
Filed: 1938-06-10
Abstract: 515,793. Railway signals. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL,CO., Ltd., GOLDING, A. J., and HORLER, F. June 10, 1938, No. 17286. [Class 105] For the control of electrically interlocked railway signals and points there are used relays having separate windings respectively energized over an interlocking circuit containing contacts associated with conflicting signals and points and over a circuit containing track section or detector section relay contacts. The relay shown has a pair of windings 1, 3 by which it is set to normal position and a pair of windings 2, 4 by which it is set to reverse position. The normal contacts such as 5, 6 are operated by a bar 9 attached to the armature of winding 1, this armature being latched up by a pawl 13 which has allowed a spring contact 15 to open, thereby deenergizing the winding 3 which in turn opens a contact 21 to de-energize the winding 1 ; thus current only flows during change-over of the relay. To operate the relay 'to the reverse position the hand lever contact 34 is set to the reversed position, whereupon the reverse winding 2 is energized by a circuit over a contact 36 (closed if other apparatus is not in a conflicting position), the reversed hand lever contact 34, the reverse winding 2, and spring contact 16 so that the winding 2 lifts its armature 18 to close a contact 20 which effects the energization of the reverse winding 4 by a circuit over a contact 38 (closed if the track section or detector section is free), front contact 20 of the armature of the reverse winding 2, back contact 23 of the armature of the normal winding 3, and the reverse winding 4. The armature 12 of the reverse winding 4 is latched up by the pawl 14 which opens spring contact 16 to de-energize the winding 2 which in turn opens contact 20 to deenergize, the winding 4. When the winding 2 was energized an extension of its armature acted, by a pin 32, on a lever 26 which released the latched-up normal armature 11.

Valves 28, 34, Fig. 3, may be provided in the members 15, 17 so as to seal them when separated, the former valve being fixed by its stem 27 and provided with a movable seat 29, while the latter valve is movable against a fixed seating 36 the ends of the valves abutting in a fluid-tight manner when the coupling is effected. The members 15, 17 have interfitting projections 25 and recesses 26, and are held together by spring clamps 23, or as shown in Fig. 5, by means of a lever 46 which operates an eccentric pin 44 in a slot 45 in a plunger 37, so as to force the members 15, 17 axially together and'against a fixed abutment 38. The members 15, 17 are formed with radial grooves engaging locating-bars 49, 50, so that angular adjustment of the members may be effected by varying the particular grooves which engage the bars. In a modification the members 15, 17 are clamped together by a plunger actuated by fluid pressure. The locating-bars, instead of engaging grooves, may carry segments bearing on the peripheries of the members 15, 17.

Abstract: 126,080. Scott, E. K., and Howles, F. Dec. 2, 1916. Gases, treating with electric discharge.-In a nitrogen-oxide furnace, the are chamber is bounded by three refractory blocks n, each of which is provided with apertures for the watercooling pipes o of one electrode, and for the adjustable carrier pot a fin q at the lower end of the electrode. Adjacent vertical faces of the blocks n are grooved to hold cement. and are recessed at r to form windows, glazed with mica or silicas. Insulators u around the pipes o allow expansion of the electrodes. The electrodes c are supported on water-cooled backings by hooks at the upper ends of the electrodes, optionally aided by bolts or other fastenings. They are arranged so as to form an inverted pyramid, as described in Specification 3953/15. Air passes upwards between the electrodes from a pipe b terminating in a nozzle b<1>, which is adjustable laterally by means of bolts and slots. Within the pipe and nozzle is a sparking-rod e, which can be raised or lowered by means of an eccentric f on an insulating-rod g. This rod is partly hollow to contain a conductor to the eccentric. Hand-holes j in the pipe b and bottom casing a afford access to the sparking-rod. An expansion joint k may be provided in the pipe b. Above the furnace is a steam-generator with water-tubes v and fire-tubes w. A fire-brick ring w<1> made in segments confines the flow of hot gases from the furnace to the generator.

Abstract: 956,735. Pipe couplings. FMC CORPORATION. May 8, 1962 [July 13, 1961], No. 17581/62. Heading F2G. A pipe coupling 10 comprises a first 11 and second 12 coupling members locked together and a sealing ring 22 located in an annular, elliptical cross-sectioned chamber 21 formed by co-operating annular grooves 19, 20 in the coupling members. A fluid-pressure differential across the pipe and hence across chamber 21 increases the effectiveness of the sealing by forcing ring 22 towards the end of the major axis of the elliptical cross-section. Further co-operating annular grooves 23, 24 are provided in members 11, 12 into which keeper balls 25 are introduced through an access port 26 to prevent relative axial movement of the members. Relative rotation is prevented by a continuous or broken weld 27. In modifications (Figs. 2, 3, 4, 5, not shown), two sets of co-operating annular grooves housing keeper balls are provided. The access ports are circumferentially spaced, tapped and provided with grub screws the inner ends of which are formed to co-operate either with the bottom of the grooves (Fig. 2), with keeper balls (Fig. 3), or with large locking balls which deform the edges of their respective grooves (Fig. 5, not shown), to prevent relative rotation. In the construction shown in Fig. 6 the keeper balls 105 are held in the annular grooves 103 by cover plates 107 and snap rings 108 housed in access ports 106. Relative rotation is prevented by an arcuate spring steel rod or wire 104 held in an arcuate groove machined between the access ports 106 and in the outer surface of coupling member 93. In a further embodiment (Fig. 7), a grub screw 115 prevents the relative rotation and relative axial movement is limited by a longitudinally split sleeve 116, flanges 117, 118 of which co-operate with grooves 119, 120 in the two coupling members 111, 112 respectively. The parts of sleeve 116 are retained by a sleeve member 121 and snap ring 123.
