Filed: 1972-03-23
Abstract: 1338182 Iron-based pre-alloy powders M KOEHLER 23 March 1972 [24 March 1971] 13773/72 Heading C7A and C7D Valve seating rings are produced by providing a powdered pre-alloy containing in weight per cent:- 1 to 2% nickel 1 to 2% molybdenum 6 to 7% cobalt optionally 1 to 2% chromium and 0.3 to 0.5% titanium the balance being iron; adding to the powder prealloy 0.5 to 1.0% carbon and 0.7 to 1.5% lead, both percentages being based by weight on the weight of the pre-alloy; brignetting the mixture; sintering; hot or cold recompressing; and optionally tempering. Thevalve seating rings represent an improvement over rings produced from powder mixtures without any pre-alloying, enabling a lower cobalt content to be used.

Title: Improvements in or relating to parachutes
IPC: B64D1/02
Filed: 1922-05-19
Abstract: 199,909. V. L. Oil Processes, Ltd., (formerly V. M. L. Experimental, Ltd.), and Lucas, O. D. May 19, 1922. Parachutes. - Relates to parachutes provided with automatic means for reducing the resistance offered by the parachute when the airpressure becomes so great as to tend to injure the fabric. In a construction specially suitable for carrying pyrotechnic flares &c., the fabric is in the form of an endless band A, Fig. 1, having a depth approximately equal to one third of its diameter, the outer or lower edge of the band being connected by rigging ropes a' to a ring A<1> 'connected by cords a<1x> to the hook A<3> taking the load, and the upper or inner edge being connected by ropes a<2> to an elastic cord A<2>, the lower end of which is connected to the hoolc A<3> by ropes a<2x> passing through the ring A<1>. The length of the rope is such that in the normal sustaining condition the upper edge of the band A is drawn inwards to cause the fabric band to take the form of an annular ring as shown. When the resistance offered by the fabric band A becomes excessive, the spring A<2> stretches and permits the inner edge to rise, thereby automatically decreasing the sustaining power. The spring A<2> then re-acts to draw the inner edge downwards again to its normal sustaining position. In the modification shown in Fig. 3, the position of the inner edge may also be varied during descent by a handrope A<4> by means of which the spiral spring A may be contracted or permitted to stretch at will, the rope A<4> being fixed to the ring a<4> and passing over pulleys a<5x>, a<4x> attached to the lower and upper rings a<5>, a<4> respectively. If the maximum velocity is not too high the spring A<2> may be dispensed with by passing the cords a<2x>, Fig. 4, over pulleys a <6> connected to the load A<6>, and fastening them to the ring A<1>, stops a', a<8> being provided on the cords a<2x> for limiting their movement. The load A<6> resists upward movement of the inner edge of the band A until the air-pressure exceeds a predetermined limit, when the cords a<2x> run over the pulleys a<6> and permit the edge of the band to rise. A hand line may also be employed in this modification.

Abstract: 874,953. Making turbine blades; destructive cores. WIGGIN & CO. Ltd., HENRY. May 8, 1957 [May 8, 1956], No. 14275/56. Classes 83 (2) and 83 (4). A method of leaching filler from a hole in an alloy article by an acid solution that attacks the filler exclusively or preferentially comprises inserting in the hole one or more wires which are substantially unattached by the acid during the process. A single wire may be inserted after some filler has been leached out to form a hole, and may be allowed to move freely so that it descends the hole under gravity as the filler is leached out, or it may be mechanically agitated. Preferably the wire or each wire is a core in the filler. A filler with one or more cores may he made by drilling a billet of filler material and inserting in the drilled billet one or more acid-resisting cores. The, whole may then be converted to rod and cut to the required length for insertion in a drilled hole in a billet from which a turbine blade or other article is to be formed. When a single wire is incorporated in a filler rod it is, preferably disposed asymmetrically; best results are obtained when more than one core is inserted in a billet of filler material, but the total area of core should not exceed 25% of that of the billet. The filler for turbine blades of nickel-chromiumcobalt alloy may be mild steel or 88% iron, 10% manganese, 2% titanium alloy. The core wires may be of a nickel base alloy containing about 15% chromium and 8% iron. Specifications 763,115 and 765,119 are referred to.

Title: Improvements in machines for marking lines upon roads and other surfaces
IPC: E01C23/20
Filed: 1929-05-08
Abstract: 326,091. Jones, T. M. May 8, 1929. Ground-markers.-A machine for marking lines upon roads, tennis courts and other surfaces comprises a closed paint or colour container mounted in association with a brush or the like upon a carriage, the container in its normal position of operation being adapted for a continuous gravity feed of paint to the brush, but being adapted for inversion so as to reverse the flow and cut off the feed on completion of the marking operation. The container a, Fig. 4, and the brush l are adjustably mounted on a carriage supported on ground-wheels f and adapted to be propelled over the ground by a handle z. The paint issues, by gravitation, in ribbon form from a linear outlet c and is applied to the ground by the brush, the rate of feed being capable of regulation by adjusting of the pressure of the brush against the outlet. Auxiliary wheels s at each side of the brush prevent undesirable widening of the brush due to irregularities of the ground. On completion of a marking operation, the machine is inverted so as to rest on the closed end b, Fig. 5, of the container and thus discontinue the feed of paint. Inverted V-shaped troughs y at opposite sides of the outlet c intercept the drips of paint when the machine is in the inverted position. A filler cap wand an adjustable vent cap x are provided.

Abstract: 1338254 Powder blower FISONS Ltd 19 April 1971 [25 March 1970] 14544/70 Headings A5R and AST  A device for dispensing finely dispersed powder into the nose, throat, or lung of a patient comprises an elongate housing having a passageway connected to means to force air through the passageway, and a chamber in the passageway to receive a container for the medicament, and perforating means which can reciprocate along the axis of the housing to perforate the container. The container is mounted in a chamber 4 of the housing 1 and may be perforated at both ends by a needle 7 mounted on a block 8 which can run longitudinally in a guide sleeve 9. The block 8 is attached to the end of a rubber bulb 14 and moved by pressing the bulb in the direction of arrow A. When the container has been pierced at both ends the bulb is released and returns to its normal position as air enters through a non-return valve 15. The perforating means are thus withdrawn to a position where a shoulder 17 of the block is forced against a projection 18 on the sleeve by the returning bulb. The bulb is then squeezed in the direction of arrows B and air is forced through the windows 13 in the sleeve and through the container, and the powder is blown from nosepiece 2 at the end of the housing. A perforated disc 11 prevents the spillage of powder into the bulb when the container is pierced, and has an aperture for the passage of the needle 7. In an alternative embodiment the needle is fixedly supported within a sleeve (21) which is longitudinally slidable about a second sleeve (9) which houses the chamber (4) and powder container, Fig. 2 (not shown).
