Abstract: 1,207,854. Sodium hydrogen sulphite. FARBENFABRIKEN BAYER A.G. 6 Oct., 1967 [13 Oct., 1966], No. 45817/67. Heading C1A. SO 2  is absorbed in the first stage of an absorption process by an aqueous solution of Na 2 SO 3  and NaRSO 3 , and the depleted SO 2  passes to a second absorption column, where it is washed with a similar solution, e.g. containing 180 to 230 g/l. of Na 2 SO 3  with corresponding concentrations of 220 to 140 g/l. respectively of NaHSO 3 , at pH 6 to 7. The pH of the solution in the second stage is maintained by the addition of aqueous NaOH solution of concentration 10-40% by weight, or of aqueous Na 2 CO 3  solution, and the whole process is maintained at a temperature of 15‹ to 90‹ C. The effluent of the second absorption stage is partly cycled as washing liquid for the first stage via a buffering vessel, and partly recycled through the second stage, the amount of recycle depending on the rate of removal of NaHSO 3  from the system and being such that precipitation of Na 2 SO 3  in the absorption columns is avoided. The effluent of the first stage is run off as product via a buffering vessel, whence it may be partly recycled through the first stage to allow for fluctuations in the SO 2  content of the feed gases, which may be roasting gases or other SO 2 -containing gases. The product solution contains 30 to 45% NaHSO 3  by weight.

Filed: 1970-09-29
Abstract: 1294739 Selective printing SCOPE Inc 29 Sept 1970 [13 Feb 1970] 46183/70 Heading B6F An impactless printer has a printing head 15 with a plurality of stylii 17 which reciprocates across the face of the paper 19 to be printed. A , continuous belt 25 is driven between the head 15 and the paper 19 below the printing stylii 17. Means 37 are associated with the belt so as to drive the head in a scan manner across the paper against the bias of a spring 23. At the end of the line, the head is released from the influence of the belt 25 and returns to the left hand side of the paper. In (Fig. 2) the printing head 15 is pivotally and slidably mounted on a rod (13) extending across the width of the paper. When a lower leg (45) of the head 15 rests in and rides along an angular scan channel (51), the stylii 17 are forced into contact with the paper 19. However, when leg (45) rests in and rides along return channel (53), the stylii are removed from contact with the paper. Change-over from one channel to the other is achieved with deflecting springs (57, 59, Fig. 3). Rigid L-shaped members 33, 35, 37 and 39, Fig. 1, are secured to belt 25 at spaced intervals and contact the head 15 to drive the same. Alternatively, apertures (70, Fig. 6) are engaged by a pin (77, Fig. 7) carried by the printing head 15 when it is pivoted to the printing position. In (Figs. 8 and 9), the head is removed from the paper in a direction transverse to the plane of the paper. The head (85) comprises a substantially planar body which rests in and rides in a scan channel (81) and a return channel (83) which are parallel to each other. When the head reaches the end of a line, deflector springs (93 and 95, Fig. 9) move it in a direction transverse to the plane of the paper from one channel to the other. Margin stop.-Upon receipt of a carriage return signal, the head 15 is driven at high speed to the end of the line, and returns itself to the left hand end where it is picked up by the driving belt still moving at high speed. It is then carried a short distance to a left hand margin switch (68, Fig. 4) which establishes the left hand margin.

Abstract: 1,188,324. Papermaking; non-woven fabric. DOW CHEMICAL CO. 24 Feb., 1967, No. 47024/69. Divided out of 1,188,322. Headings D1R, D2A and D2B. A dry non-woven fibrous sheet is made from a web of self-bonding, non-fibrillated gel fibres (defined as in the parent specification) of thermoplastic fibre-forming polymers of acrylonitrile, by drying it under conditions that cause the gel fibres to collapse while restraining shrinkage of the web. The restraint may be applied by tensioning the web in its plane or by a compressive force applied to its face, e.g. by pressing it between two belts moving with the web, at least one of the belts being foraminous to allow vapours to escape. The restraint may be applied throughout the drying period, or only in its earlier part (when most of the shrinkage would otherwise take place), or intermittently, e.g. by passing the web continuously over a series of dryer rolls, wrapping it alternately clockwise and counterclockwise, while restraining it to constant length. The dried web may subsequently be annealed at a temperature at least 30‹C above the glass-transition temperature of the fibres. The web may be formed by a scattering mechanism, distribution by a stream of air or water, or deposition by filtering from a liquid. Staple fibres are preferably formed into a web by papermaking technique, continuous filaments also from suspension in water, or by collecting the filaments side-by-side as in a tow, but preferably with a little cross-lay. The rate of drainage of aqueous slurries may be controlled by the process of Specification 1,188,323. The gel fibres may be toughened before sheet-formation by subjecting them while free of restraint to a hot aqueous medium, but they must then be cooled before subjecting them to stress.

Abstract: 983,526. Insulators. BRITISH INSULATED CALLENDER'S CABLES Ltd. Dec. 13, 1963 [Dec. 14, 1962], No. 47300/62. Addition to 878,073. Heading H2C. The insulator described in the parent Specification, in which a central resinbonded glass fibre rod is enclosed in a waterproof cover consisting of a plurality of short tubular bodies of ceramic or vitreous insulating material, is modified for use as a sectionalizing runner for overhead electric traction systems by making each short tubular body with a main central part 8 (Fig. 2), the underside of which is co-planar with the undersides of the terminal fittings 3 (Fig. 1), and with tapered end parts 9, so that a current collector can pass from body to body without encountering a sharp corner. Flexible washers 10 made of P.T.F.E. or similar material may separate adjacent tubular bodies and have tapered spigots fitting corresponding recesses therein. The tubular bodies and the washers may either fit directly on the central rod or be separated therefrom by a layer of insulating material, e.g. a grease or an elastomer. Each metal terminal fitting 3 is drilled to receive the central rod 1, which is secured therein by a compression joint. A clevis 4 is provided for attachment to the adjacent section of the overhead line. A metal sleeve 14 containing a flexible P.T.F.E. liner 13 is interposed between the terminal fitting and the last tubular body 7. During manufacture, the end faces and inner surfaces of the tubular bodies are primed with a suitable material, are threaded on the rod, the ends of which are masked, and the whole is then subjected to a vacuum, followed by impregnation with insulating material, e.g. silicone rubber. Finally, after fixing the terminal fittings &c., surplus impregnating material is removed from the running surfaces. The insulator may be assembled with the central rod in a pre-stressed condition. An application of the runners in the construction of a neutral section for an overhead electric railway system is described (Fig. 5, not shown).

Abstract: 1346662 Vehicle stabilizers RICHIER 12 Oct 1971 [12 Oct 1970] 47507/71 Heading B7J [Also in Divisions E1-E2] A mobile load-handling machine has two pairs of stabilizing pivotable legs arranged one pair 10, 11 (11 not shown) at the front and one pair 12, 13 at the rear, at least one of these pairs (e.g. 12, 13 as shown) being mounted on acrossbeam 4 pivotally attached about an axis 5 perpendicular thereto and parallel to the longitudinal vertical median plane of the chassis 1 of the machine, to the chassis 1, and the crossbeam 4 is able to be immobilized about the axis 5 relative to the chassis by means, such as two single-acting hydraulic or pneumatic jacks 18, 19, which can also pivot the cross-beam 4 about the axis 5 if either leg 12 or 13 ceases to bear upon the ground during operation so as to cause that leg 12 or 13 to resume bearing upon the ground. The chambers of the jacks 18 and 19, which are connected between the chassis 1 and cross-beam 4 on either side of the axis 5, can be put into communication to cause pivoting of beam 4 when a difference in pressure exists between the two chambers due to loss of ground contact by a leg 12 or 13. The stabilizing legs 10, 11, 12 and 13 are raised and lowered by double-acting hydraulic jacks 14, 15, 16 and 17 (15 not shown). The chambers of a pair of these jacks, e.g. 16 and 17 associated with one pair of legs 12 and 13 may be put into communication so that when a leg 12 or 13 loses ground contact, the pressure difference between these chambers causes lowering of the leg to re-establish contact. A suitable hydraulic/pneumatic control system is described with reference to Fig. 2 (not shown). One pair of legs 10 and 11 may be mounted on a cross-beam 3 fixed rigidly to the chassis 1.

Abstract: 1,081,107. Number printing. ENGLISH NUMBERING MACHINES Ltd. Nov. 25, 1964, No. 47833/64. Heading B6C. [Also in Division F2] In a pawl mechanism for a number printing device having a pawl 41 mounted for engagement with a toothed element 34 driven by a drive member 37, a pawl actuator 45 is arranged to be moved by camming action between the pawl actuator 45 and the drive member 37, the pawl out of contact with the toothed element in response to relative indexing movement of the toothed element and the pawl. When a manually operable actuating lever 1 of the printing device is rotated in a clockwise direction about a spindle 2 the end 4 of the actuating lever strikes a cam 5 to pivot a lever 7 in an anticlockwise direction about a spindle 12 to disengage a notched portion 15 from a spindle 14 so that the levers 16 and 22 pivot together about the spindle 24 under the action of a spring 9. During this movement a printing wheel support 29 pivots in a clockwise direction about a spindle 30 until the printing wheel 34 strikes against a platen (not shown). After the printing action has been effected, the actuating lever 1 is returned to its initial position shown in Fig. 1. For indexing purposes, the printing wheel 34 is provided with an indexing mechanism having a toothed drive transmitting member 37 rotatably mounted by manual or electromagnetic means on the spindle 2 and formed over a portion of its periphery with gear teeth 38 which co-operate with teeth 39 on the printing wheel 34. On a different portion of its periphery the toothed driving member 37 is formed with a plurality of projecting portions 40 formed with numerals corresponding to type face numerals formed on the crowns of the teeth 39 of the printing wheel 34. When the printing wheel 34 is rotated by the toothed member 37 an actuating motion is imparted to the pawl actuator 45 by a camming action between the toothing of the toothed member 37 and the detent portion 48 of the pawl actuator 45 which is rocked about a spindle 47 against the action of a spring 43 to move the pawl 41 about its pivot pin 42 so as to move the pawl 41 out of contact with the printing wheel 34 during the passage of the crown of each tooth 39 past the pawl 41 to prevent wear of the type on the crowns of the teeth 39.
