Abstract: 1,231,845. Railway crossings. PINTSCH BAMAG A.G. 29 April, 1968 [29 April, 1967], No. 20271/68. Heading E1G. A railway crossing frog which may form part of a switch (not shown) comprises fixed wing rails 1, 2 and convergent point rails 4, 5 whose inner ends can bend laterally and are welded together to form a movable point 3 actuated by a motor 15, e.g. in synchronism with the movement of the switch blade. At their outer ends, i.e. at and beyond sleeper plates 10b, the rails 4, 5 are anchored by clamps 8b, Fig. 5, and dowels 14. Near their inner ends, however, the rails 4, 5 are provided with spacers 12, Fig. 4 (not shown) and can bend resiliently, sliding laterally between abutments (8a) on sleeper plates (10a). The rails may have weakening recesses to facilitate bending. The motor 15 is coupled to the point 3a by a slide rod a associated with a lost motion locking device, Fig. 2b (not shown), comprising hammer-headed arms (c, d) pivoted to the underside of the movable point and cooperating with abutment faces on fixed locking boxes (b<SP>1</SP>, b<SP>2</SP>) and with recesses (a<SP>1</SP>, a<SP>2</SP>) in the slide rod.

Abstract: 1,238,037. Separation of calcium and magnesium. DOW CHEMICAL CO. 15 Aug., 1968, No. 39041/68. Heading C1A. Calcium and magnesium compounds are separated from a mixture of carbonates (e.g. dolomite) by calcining, slaking the calcinate, bringing the slaked calcinate into contact with an aqueous solution containing 6-32 wt. per cent of calcium chloride, and bringing the slurry to 0-37‹ C. for a period of time to permit the growth of hydrated calcium oxychloride crystals, and recovering the oxychloride crystals before recovering the magnesium hydroxide precipitate. The oxychloride is preferably CaCl 2 .3CaO.XH 2 O (X is 14-16) and is precipitated as large crystals, whereas magnesium hydroxide is a finer precipitate, so allowing a separation by screening. The oxychloride crystals may be contacted with an aqueous magnesium chloride solution to precipitate magnesium hydroxide and leave a calcium chloride solution. The oxychloride may also be heated or contacted with water to give a calcium chloride solution, and a calcium hydroxide precipitate.

Abstract: 1,251,528. Electric couplings. ELCO CORP. 10 Dec., 1968, No. 58720/68. Heading H2E. A printed circuit board connector assembly includes a pair of superposed metallic plates 11, 12 separated by an insulating layer 13 and forming the ground and voltage plane respectively. A casing for mounting a printed circuit board and containing contacts 35 is of modular construction and consists of end guides 18, 19 and centre guides 20. The guides have apertured hubs 30 for containing the contacts which fit within aligned pair of apertures in the plates. The guides also have solid hubs 32 for securing the casing to the plates. Where electrical contact is desired to be made with any of the plates, the hub and a part (48, Fig. 1) of the base of the casing is removed and a pair of aligned apertures 56, 57 of different sizes provided on the plates. The contact element 35<SP>1</SP> or 35<SP>11</SP> is fitted with a metal bushing 51 which engages the smaller aperture 56 making electrical contact while making no contact with the larger aperture 57. When contact is to be made with the lower plate, the larger aperture 57 is on the top plate and the metal bushing is fitted with an insulating bushing 58. The nose ends 38 of the contact elements make contact with a conductive pad (15, Fig. 1) of the printed circuit board. The tail ends of the contact elements other than those making electrical contact with the plates remain completely insulated by the apertured hubs and are suitable for backpanel wiring. In constructing the assembly, the contacts for the voltage and ground plane are inserted in the plates first, then the casing complete with the remaining contacts is added, the removal of the hubs and the casing base in the positions occupied by the voltage and ground planes allowing this to be done. If a doublesided printed circuit board is to be used, a row of contacts is provided along each side of the board casing (Fig. 6, not shown). In another embodiment (Fig. 7 not shown), three or more metal plates separated by insulating layers are used. Reference has been directed by the Comptroller to Specification 1,130,833.

Sulphur-bearing petroleum atmospheric or vacuum residues are deasphalted by treating them with solvents comprising C 4-8  paraffinic hydrocarbons at a temperature above the softening point of the asphaltene concentrate and under liquid-liquid extraction conditions and the resulting deasphaltizate is subjected to destructive hydrogenation using a catalyst comprising cobalt and molybdenum oxides on an aluminium oxide carrier at 350-450‹ C., 100-300 atm., a space velocity of 0À2-5 per hour and a ratio of hydrogen to deasphaltizate of 200- 2000 : 1 by volume. The solvent extraction is suitably carried out at 140-190‹ C. using a countercurrent of an individual paraffinic hydrocarbon or a mixture such as a light petrol boiling below 65‹ C. The deasphaltizate can be diluted, e.g. with gas oil or hydrogenated gas oil, before the hydrogenation. The hydrogenated material is distilled to produce fractions having low sulphur contents such as, petrol, diesel fuel, and boiler fuel. The separated asphaltenes containing ash forming components and metals can be used as components of bitumens and lacquers and binders for briquetting coal fines.

In one embodiment. Fig. the filter tow strip 106 is opened by air jets 121, 124, is stretched by a device 171, is sprayed with softener by a device 131, and is then wrapped and cut into filter plugs 114. The stretching of the tow strip 106 in a loop 178 between pairs of rolls 173, 174 is effected by a weight loaded roller 176. The size of the loop 178 is maintained within limits by varying the speed of drive to the roll pair 173 by means of a variable speed gear 186 controlled by a motor 184 in response to changes in the height of potentiometer wiper 182 that is fixed to the weight load of the roller 176 and is connected to a power amplifier 183. The rod forming belt 109 is driven at a constant speed, while the rate of feed of the filter tow strip 106 is varied by varying the speed of the driving motor 133 in response to measured variations in the air resistance of the filter rods 114 in the same manner as the speed of the motor 40 is varied in Specification 1295863. In another embodiment, Fig. 2 (not shown), the rate of feed of the filter tow strip is kept constant while the speed of the rod forming belt is varied in response to detected variations in the air resistance of the filter tow strip measured just before it passes onto the forming belt. Other alternatives mentioned are varying the speed of the rod forming belt in response to variations in the air resistance of the filter rods, and varying the rate of feed of the filter tow strip in response to variations in the air resistance of the filter tow strip.

In use, a dial 22 of a micrometer screw 20 is first set thereby determining a working gap between the pattern 8 and the substrate 9. The lower space between a movable sleeve 15 and a rod 13 is supplied with e.g. compressed air, thereby causing the rod 13 to rise in the sleeve. This pivots a lever 17 into contact with a stub 19 of the screw 20. The rod 13 and sleeve 15 then rise together until  the pattern 8 and substrate 9 come into contact. The sleeve 15 is held in this position while the rod 13 is allowed to descend over the set working gap, thus bringing flanges 14, 16 into contact. The microscope (5) is then used to accurately align the now parallel pattern 8 and substrate 9. The substrate is again raised and the exposure is made.
