Tar oils, extracting and purifying; oils for burning.-A refined oil obtained from the residue from the benzol plant or from the Light oil residues from crude benzol is combined with a small quantity of crude) benzol or petrol for use as a fuel in internal-combustion engines. The crude benzol or petrol employed may be 1-12th the weight of the refined oil. When a Simon CarvÚ's still is employed, the naphthalene oil, composed of naphthalene, water, and light oil, is run off from the base of the first water-cooled condenser, and cooled in open trays to separate the naphthalene salts, after which the light oil is drained off and distilled until the lighter oil, heavy naphtha, and a slight percentage of naphthalene are distilled over. The distillate, after being washed and neutralized with acid, soda., and water, is again distilled, the distillation being continued to 190‹ C. In other stills, the crude benzol is distilled to 165‹ C. to get off the benzol, toluol, and solvent naphtha. The light oil remaining in the still, consisting of about 25 per cent of the total volume treated, is distilled in the same way as the light oil from Simon Carve's still.

Abstract: 813,568. Controlling aircraft. PAYEN, R. N. May 10, 1955 [May 10, 1954; Oct. 6, 1954], No. 13557/55. Class 4. Apparatus for increasing the positive incidence of a tail-less aircraft comprises at least two opposed retractable control surfaces mounted on a fin or port of the fuselage of the aircraft to open and close as a pair. In one embodiment, shown in the Figures, a tail-less aircraft has a fuselage 4 extending into a fin provided with hinges 5 for a pair of flaps 3, 31 which may be opened in unison from the dotted to the full-line positions shown in Fig. 5a. This results in the application of a force Fl which, acting about the wing lift centre 2, applies an upward pitching moment during landing without impairing the lift properties of the wing. Other embodiments are described. In one the flaps are mounted on the fin forward of a conventional rudder ; in another they are mounted one on each side of a fin about fore-andaft axes for upward and outward swinging movement. In another they are mounted about substantially vertical axes at the nose of a fuselage for forward-swinging movement from retracted positions within the fuselage to extended positions transversely of the fore-andaft axis, or they may be mounted at the root leading edges of the wings for outward movement from retracted positions within the leading edges of the wings. The flaps may be operated differentially to act as rudders and mechanism for this purpose comprises a rod P connected to a lever G coupled by rods b, b<SP>1</SP>, respectively to levers G1, G4. Other levers G2, G3 are connected by rods b 2 , b<SP>1</SP> 2  to operating levers 12 on flaps 3. Two concentric tubes T, T1 on an axis BB1 are pivotally mounted on levers 13 fast with a tube mounted for rotation on an axis CC1. A lever 14 is fast with the tube CC1 and is rotatably mounted on tube T, the upper end of the lever being connected to a jack V. Levers Gland G3 are fast on tube T1 and levers G2 and G4 are fast on tube T. With rod P inoperative operation of jack V will act through lever 14 to rock the assembly about tube CC1 to pull rods b 2 , b<SP>1</SP> 2  and thereby open the flaps in unison. Operation of rod P will cause push-pull movement in a selected direction of rod b, levers G1, G3 and rod b<SP>1</SP> 2  and rod b<SP>1</SP>, levers G4, G2 and rod b 2  to move the flaps simultaneously in the same direction whereby they function as a rudder. Subsequent operation of jack V will cause the flaps to be opened in unison from this deflected position.

Abstract: 402,672. Knitting. SCOTT & WILLIAMS, Inc., 366, Broadway, New York, U.S.A.-(Assignees of Sheppard, H. N.; 7, Lincoln Place, Maplewood, New Jersey, U.S.A.) May 11, 1933, No. 13773. Convention date, Sept. 8, 1932. [Class 74 (ii).] The heel of a seamless stocking is knitted as a segment 110 joined to the sole on each side by a suture line R along which the stitches are slackened. The segment is narrowed only, each course or a smaller number being fashioned. In the latter case either the narrowing or the widening pickers are operated intermittently. The invention is described as applied to the Scott and Williams type of revolving needle cylinder hosiery machine. At one side of the stocking needles are picked out of action for two reciprocations and are missed by the picker after the third course in reverse direction. The complemental cycle of operations is carried out on the other side. When the narrowing pickers are tied together by a lostmotion link, the periodical interruption of the narrowing operation can be effected by lifting one of the pickers at the necessary intervals. Lugs on the side of the main pattern chain act, by intermediate connections, on a finger 32 overlying the rear end of a pivoted idling catch 33, which underlies, at the front end, one of the narrowing pickers. When the catch 33 is tipped by the action of the pattern chain the picker is raised out of action. After the segment 110 has been narrowed to the desired point a course is put in to form the suture line R. To avoid puckering, the stitches are slackened for a number of courses along the suture by a cam 38 Fig. 8 acting to push in certain sinkers. By varying the rate of narrowing the line R may be made to assume various curvatures. When the heel to be formed by intermittent use of the widening picker, side lugs on the pattern chain normally hold the picker in place. The absence of these lugs at any particular point allows the picker to be operated. When the heel and the toe are to be made on the short and long butt side respectively of the circle of needles, as described in Specification 355,062, the lips 681 of the widening picker are made wide enough for two long-butted needles while notches 682 reduce this width by one half. Specifications 163 /57, [Class 74, Lace-making &c.], and 12722/13, [Class 74 (ii), Knitting &c.], also are referred to.
