Title: Improvements in or relating to the refining of tars
IPC: C10C1/20
Filed: 1929-12-11
Abstract: Crystalline and amorphous wax are separately recovered from tar obtained by the low temperature distillation of carbonaceous solids, by distilling the tar to produce resin-free fractions containing wax removable by gravity and pressible wax, and separately dewaxing these fractions.  The pressible crystalline wax is removed by filtering, and the amorphous wax by adding a solvent, chilling, and precipitating, the precipitated wax being removed by gravity settling or by centrifuging as described in Specifications 119,288, [Class 23, Centrifugal machines &c.], 166,031, [Class 91, Oils &c.], 186,936, 191,750, [both in Class 23, Centrifugal machines &c.], 197,389 and 201,986, [both in Class 91, Oils &c.].  Organic basic and acidic substances are removed prior to or after the fractionation by addition of caustic soda solution and removal of the dark sludge formed.  Tar of sp. gr. 0,948 obtained by low temperature distillation of lignite is distilled without decomposition, using steam and vacuum.  The first fraction comprising crude naphtha distills over between 30-160 DEG  C.  Superheated steam is then introduced into the still and fractions containing crude kerosene and gas oil are obtained after which the still is maintained under a vacuum of 690 mm.  The next fraction distilling over below 162 DEG C. contains the crystalline wax, while the following fraction contains amorphous wax and distills over below 197 DEG  C., the final cut containing the resins.  The amorphous and crystalline waxes are then refined with acid and alkali and removed from their respective fractions which are further distilled in pressure of 10 per cent. discolouring clay, with steam and under vacuum to give a gas oil of 106 DEG  C. flash point, a spindle oil fraction of 160 DEG  C. flashpoint, and a still residue from which after filtration a motor oil of 245 DEG  C. flash point is obtained.  Reference has been directed by the Comptroller to Specification 201,986, [Class 91, Oils &c.].

Abstract: 1441167 Self-closing closure N B NILSON 15 Aug 1973 [15 Aug 1972] 38601/73 Heading B8T A self-closing closure consists of a cylindrical member 12 having an external radially extending flexible flange 16 at its lower edge and a frusto-conical flange 14 which forms a dispensing orifice 15 at its upper edge, the flange 16 terminating at its outer and inner edges by downwardly projecting flanges 17 and 18 respectively ; and a second cylindrical member 1 having an internal screw thread 3, an external radially extending flexible flange 4 at its upper edge and a tubular nozzle 9, integrally mounted above the screw threaded portion of member 1, closed at its upper end and having dispensing orifices 11 in its side wall and an external annular groove 20 around its upper end, the flange 4 terminating at its outer and inner edges by upwardly projecting flanges 5 and 7 respectively. The members are engaged by inserting the tubular nozzle 9 concentrically into member 12 and snap engaging flanges 17 and 18 with flanges 5 and 7 respectively by the co-operating beads 6 and 8 and simultaneously snap engaging the internal edge of dispensing orifice 15 with groove 20. The assembly is screwed on to a closure adapted to allow manual pressurizing of fluid contents. The member 12 is pulled away from the container so as to disengage flanges 7 and 18 and orifice 15 and groove 20, but not flanges 5 and 17, unlocking the closure. This position is not shown in the drawings. Pressurizing the fluid contents of the container forces the contents into the void space between the members 1 and 12 which causes flexing of the radial flanges 4 and 16 moving orifice 15 away from a bevelled shoulder 19 of the tubular nozzle 9 opening the closure. Relief of pressure allows elastic memory to reclose the closure which may subsequently be locked by snap fitting the respective parts as described above.

Abstract: 896,145. Electric motor control systems. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES,  ALSTHOM. Dec. 3, 1958 [Dec. 6, 1957], No. 39015/58. Class 38 (3).  A traction system comprising a number of motors 1 each having an armature 2 and a series field 3 has means 6 provided whereby should the current I in the series field 3 tend to be reduced because of slippage of the wheels driven by the motor 1 a current Y appears at terminal 12 of the means 6 which is fed to the junction of the armature 2 and field 3 where it adds to the armature current J, thus tending to restore the field current to its normal value, the current Y being the resultant of the field current I compared with a reference current I o . Fig. 4 shows a traction system comprising two motors 21, 22 in which system the means 6 takes the form of an amplidyne 29. The amplidyne has a series field 32 and a control field 33 whilst auxiliary fields 34 . . . 37 are provided whereby inequalities of the system may be compensated. When the system is running normally without wheel slip the potential at points 49, 50, respectively, of the motors 21, 22 will be equal and no current will flow in the control field 33 of the amplidyne 29, hence no current will flow from the amplidyne 29 to aid the current flowing in either field 25 or 26. Should, however, the wheels being driven by, say, the motor 21 slip, the current in the field 25 will tend to be reduced, thereby destroying the voltage equality at the points 49, 50. Current will flow in the control field 33 whereupon the amplidyne will produce current which will be fed to the field 25 and so maintain the field current at its normal value. A source of current 46 may be provided together with rectifiers 51, 52 and variable resistors 53, 54, whereby the threshold value at which the control begins to be effective may be adjustable. Alternatively the amplidyne may be replaced by a magnetic amplifier or by an " image circuit " not subject to wheel slip. The rectifiers 51, 52 may be " Zener " diodes and an indicator or alarm 60 may be provided.
