Abstract: 509,861. Drying-oils; coating and impregnating-compositions. NAAMLOOZE VENNOOTSCHAP INDUSTRIEELE MAATSCHAPPIJ VOORHEEN NOURY & VAN DER LANDE. May 12, 1938, No. 14223. Convention date, June 26, 1937. [Classes 91 and 95.] [Also in Groups IV and VIII] Drying-oils or substances for use in coating or impregnating materials are obtained by heating to above 150‹C. a mixture of "Isano" (or "Ougueka") oil with one or more of the following :-drying, semi-drying, or non-drying vegetable or fish oils; tall-oil or esterified tall-oil; sulphurized, oxidized, or polymerized products of the above; natural or artificial resins; waxes; paraffin; high or low m.w. hydrocarbons; varnish solvents or diluents. The heating may be effected under reduced or raised pressure, and preferably while carbon dioxide, nitrogen, or other inert gas is led through or over the mixture. The " Isano " oil may first be fractioned by solvents. The oil may be heated in a high-boiling solvent which is afterwards distilled off under reduced pressure. Objects may be coated or impregnated with the untreated mixture with or without a siccative or a pigment, and heated to the desired temperature. Thus tin is coated by applying a mixture of 6 lb. of linseed oil with 4 lb. of "Isano" oil and heating for 2 hrs. to 180‹C. in a muffle furnace; or impregnated wood fibres, linoleum, artificial leather, and electric cables are made direct. In examples :(-1) A polymerized oil is obtained by passing a 6 : 4 mixture of linseed oil and "Isano" oil through a heated tube so that it is maintained at 240-260‹C. for 20-25 min. (2) 70 lb. of soya oil mixed with 30 lb. of "Isano" oil is maintained at 250‹C. for 1 hr. (3) 8 lb. of colophony, as such or as glycerol ester, is mixed with 2 lb. of "Isano" oil and maintained at 250‹C. for 3 hrs.; the product is dissolved in artificial turpentine.

Title: Balanced-octane gasoline manufacture
IPC: C10G59/06
Filed: 1965-12-03
Abstract: A method of producing, from low octane naphtha, motor gasoline having balanced octane across the boiling range thereof, which gasoline consists essentially of catalytic reformate and sufficient light hydrocarbons to produce the desired gasoline vapour presure, comprises distilling said naphtha to produce a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction, blending selected portions of each of said fractions to produce a reformer charge stream and subjecting said charge stream to catalytic reforming to produce a reformate having balanced octane across the boiling range thereof, and blending said reformate without further treatment with light hydrocarbons to produce said gasoline. By selecting different proportions of the three cuts, end-products of varying octane numbers may be produced.

Title: Improvements in self-propelled vehicles
IPC: H03K5/13
Filed: 1968-11-04
Abstract: 1,242,560. Vehicle safety devices. AMERICAN CHAIN & CABLE CO. Inc. 4 Nov., 1968 [2 Nov., 1967], No. 52153/68. Heading B7H. In a motor vehicle 10 having a safety bumper including a switch 15 which is actuated upon engagement with an obstacle to stop the vehicle, means are provided which will stop the vehicle either in response to closure of a switch 15 or to breakage of electrical leads L 1 , L 2  connected thereto. The vehicle 10 has sensing coils which guide the vehicle along a wire embedded in a slot 12 in the floor 11. The safety bumper is fixed to the front of the vehicle 10 and comprises two flexible metal strips 13, 14. The switches 15 each comprise two continuous strip contacts 16, 17 arranged to be closed when the outer strip 14 is deflected by an obstacle. A battery B is connected through a current-limiting resistor 25 both to the contact 16 of the switch 15, and to the contact 17 by way of a resistor 20. The base of a transistor Q 2  is connected to the lead L 1  through a current limiting resistor, and the base of a transistor Q 1  to the lead L 2 . The emitters of the transistors Q 1 , Q 2  are grounded and the collectors connected to an " OR " gate 18 and to a voltage source V through respective resistors. When the switch 15 is open and the leads L 1 , L 2  are intact the transistors Q 1 , Q 2  both conduct, but if the switch is closed or one of the leads broken or left disconnected one of the transistors will not conduct so that the potential at its collector is applied to the " OR " gate 18 to produce a signal for stopping the vehicle. In Fig. 4 (not shown) there is provided a secondary protective circuit comprising a relay (K1) which is connected between the battery (B) and contacts (16, 17) and has a normally closed contact (K1A) between its coil and the battery, a silicon controlled rectifier (SCR-1) in series with the relay, and a line (22) for supplying control relays for controlling the vehicle drive motor and brake. Momentary closure of a starter switch (21) connected to the gate lead of the rectifier in association with resistors (23, 24) fires the rectifier to supply the control relays. Insufficient current normally flows through the coil of relay (K1) to open the contact (K1A), but if the switch (15) is closed the relay is activated and the voltage supply to the control relays is cut-off until the starter switch is next closed to fire the rectifier.

After grass 5 has grown, it is mown several times before layers 2, 3 are cut into strips and rolled up. Alternatively, seeds may be sown on top of the felt layer or between two felt layers and the growth medium is omitted. The cellular concrete may be replaced by a water pervious layer comprising non-woven glass fibres held together by a synthetic resin.

A method of attaching a lead to an electrical component comprises forming a row of a number of electrical components 17 spaced from each other, each end of each component having an outwardly extending lead 18 with a conductor 15, 16 at each side and substantially parallel to the row, securing the leads 18 to the conductors, severing each lead of a first component adjacent the respective conductors on the sides opposite the component at 20 and severing the conductors between the associated lead of the first component and the corresponding lead of the next-in-line component, the conductor severing locations being spaced in the same direction along the row from the first component. The leads may be welded to the conductors and a number of severing operations may be performed simultaneously. The conductors may be wrapped around the leads or the latter may be located in holes in a strip conductor, Figs. 3, 4 (not shown). Each component thus has a lead at each end extending outwardly therefrom and then transversely thereto, the spacing apart of the transverse ends corresponding to the distance between holes in a circuit-board.
