Filed: 1975-05-02
Abstract: 1514172 Vehicle electrical systems LUCAS ELECTRICAL LTD 2 May 1975 [16 May 1974] 21732/74 Heading H2H The interior lamp of a vehicle is arranged to remain illuminated for a predetermined time after a vehicle door has been closed only if the hand-brake is on. The interior lamps 28 of a road vehicle are connected to the vehicle battery 11 by way of a normally open contact 27 of a relay 24 and a switch 25 which is closed when the handbrake is on. Opening of a vehicle door closes a switch 16 or 17 causes the rapid charging of a capacitor 15 and the transistors 21, 22 turn on to energize the winding of the relay 24 to close contact 27 thereby illuminating the lamps 28 if the switch 25 is closed by the handbrake being on. Closure of the door opens the switch 16 or 17, the transistors 21, 22 then remain turned on by the discharge of the capacitor 15 for a period of say, 60 seconds, to maintain the illumination of the lamps 28 for that time. Should the handbrake be released, the lamps 28 will be extinguished.

Filed: 1974-05-16
Abstract: 1467346 Burners GAZ DE FRANCE 16 May 1974 [16 May 1973 11 Oct 1973] 21886/74 Heading F4T A pressure regulator 5 supplying a burner 2 through a line 1 and a valve 6 has a by-pass 10 connected to a reservoir 7 to receive gas which continues to flow through the regulator after the valve 6 has closed. Unnecessary operation of the burner's safety device by an undue rise in pressure in the line 1 is thus avoided. The valve 6 may be closed electrically simultaneouslywith a valve 11 to which it is connected by leads 12, 13. In normal operation, a vacuum is maintained in the reservoir by a Venturi 9. The valve 11 may be replaced by a fluidoperated valve. In a further modification, the fluid at increased pressure in the line 1 enters the reservoir through a valve (24, Fig. 3) which is opened by fluid-pressure from the by-pass 10 or through an electrical delay relay (20) after the valves 6 and 11 have closed. The convergent and divergent passages (9e, 9f, Fig. 5) of the Venturi may be adjusted by screwed connections to vary the size and position of the throat (9g). The passage leading from the throat has a cross-section greater than that of the inlet to the divergent passage and less than that of the by-pass returning the flow to the line 1.

Title: Bleaching woob pulps
IPC: D21C9/14
Filed: 1956-07-17
Abstract: A slurry of wood pulp, e.g. sulphite wood pulp, is treated with chlorine dioxide and then with a sulphite, bisulphite or thiosulphate, e.g. of sodium, potassium or ammonium, or with a substance, e.g. sulphur dioxide, capable of reacting with a compound already in the slurry to form a sulphite, bisulphite or thiosulphate. The pulp may have been subjected to an initial purification process, e.g. with chlorine or a hypochlorite followed by alkali extraction. The pulp, which may have a pH of 5 to 9, adjusted as necessary with sodium hydroxide or carbonate, is then treated with chlorine dioxide, which may be added as a gas or in aqueous solution.  Sodium bicarbonate, which may be added as such or may be formed in situ by adding carbon dioxide, may be added as a buffer.  The chlorine dioxide treatment may be effected at temperatures from 4 DEG  to 100 DEG  C. and may be followed, without intermediate washing, by treatment with a hypochlorite at temperatures from 4 DEG  to 75 DEG C. and pH from 7 to 10.  The treatment with the sulphite, bisulphite or thiosulphate may be effected at a pH between 1 and 10 and at a temperature of 4 DEG  to 75 DEG  C., and this treatment follows again without intermediate washing.  The pH at the end of the process should be from 1 to 3, to obtain which sulphuric acid may be added. Specification 787,307, [Group IV (a)], is referred to.

Abstract: 657,899. Hydro-pneumatic shock absorbers. SOC. ANON. DES ANCIENS ETABLISSEMENTS PANHARD ET LEVASSOR. Aug. 21, 1948, Nos. 22098 and 22099. Convention dates, Aug. 30, 1947, [Class 108(iii)] An hydro - pneumatic shock absorber comprises a cylinder 1 in which are displaceable two pistons 2, 13 separated by liquid, an elastic fluid acting in the space 4 between the end of the cylinder and the piston 2, the distance between the pistons 2, 13 being maintained constant by compensating for the loss of liquid by the action of a stem 8a connected to the piston 2 and adapted to open a valve 20 controlling an inlet 19 for liquid under pressure, when the distance between the pistons tends to become less than the length of the stem. The stem 8a is formed with a valve element 8 which is adapted to seat at 7 on a diaphragm 9 when the piston 2 reaches its outermost limit. This has the effect of trapping liquid on the underside of the diaphragm and thus tends to maintain equality of pressure on either side of the piston 2 and minimises escape of air under these conditions. The stem 8a and valve 8 are retained by a spring ring 10, and the valve 8 which has limited axial movement is adapted to be acted on by piston packing 3 to urge it on to the seat 9. The valve 20 comprises a piston Fig. 2, (not shown) slidable in the bore 19, and has a frusto-conical face adapted to engage the seat 22. A space 19a is left below the piston 20 when it is in the seated position. An upwardlyclosing spring-loaded ball-valve is mounted in a duct which connects the space 19a with the bore 19 above the piston. In Fig. 3, the fluid space 4 of Fig. 1 is divided into separate fluid spaces 34, 35 by a diaphragm. 36. A valve 38 urged into closing position by a spring 41 carries a stem 40. In operation, the'diaphragm 36 is held by a spring 42 in engagement with a stop 43 for travel of the piston 2 to the right of that shown in Fig. 3, flexibility of the suspension then depending on compression of fluid in the space 34, only. On movement of the piston 2 to the left of the position shown in Fig. 3, the stem 40 is engaged and the valve 38 opened, and air in both spaces 34 and 35 is compressed. The diaphragm may be engaged and moved leftwards by the piston 2.
