A device for connecting a rod 10 to a lever (not shown) comprises a bifurcated member 1 with two substantially parallel arms 2, a pivot pin 4 extending between the two arms, a spring clip 6 for retaining the pivot pin in place and a pivotable member held in the bifurcated member and spaced from the pivot pin, the arrangement being such that when the device is in use, the lever is held on the pivot pin between the two arms and the rod is rigidly secured to the pivotable member and can move pivotably relatively to the bifurcated member. As shown in Fig. 2 the pivot pin 4 passes through hollow rivets 3 in each arm 2. The pivot pin is carried by a spring arm 5 of the spring clip 6 which also has a stirrup 7 which is engaged with the member 1 to prevent axial displacement of the pin 4. The pivotable member consists of a pivot pin 8 provided with a short tube 9 to which the rod 10 is connected by a screw-thread. In a modification the member 8 instead of being provided with a pivot pin has a spherical head which engages a spherical socket in the member 1. In another construction Fig. 10 the pin 4 is provided with a groove 20<SP>1</SP> at one end and a head 19 at the other end and it is prevented from axial movement by a clip having two arms 21 which engage the groove 20 and two further arms 25 which engage the end of the pin; a two jaw portion of the clip engages one of the arms of the member 1 to secure the clip to the member. The pivotable member for the rod 10 includes a pivot pin 18. In a modification of this construction the two jaw portion 27 of the clip is omitted and instead the clip is provided with a protuberance which engages a hole in the arm of the member 1.

Filed: 1970-05-13
Abstract: 1293823 Cutting webs A HERBERT and M GUHR [trading as LEONHARD HERBERT MASCHINENFABRIK] 13 May 1970 [13 May 1969] 23249/70 Heading B4B A device for cutting through cord webs for the production of pneumatic tyres comprises two downwardly directed pointed blades 57, 57<SP>1</SP> each movable with a carriage unit 36, Fig. 6, appropriate thereto and guided in the direction in which cutting is to be effected, and a driving mechanism operable to reciprocate the units 36 towards and away from each other to cause cutting of the web by the blades the points of which at the start of the cutting operation are in mutual contact. The device is characterized in that each blade is arranged to be pivotable about the axis of a vertical spindle 44, 44<SP>1</SP> individual thereto and mounted in its carriage unit. In the device described, carriages 29, 30, Fig. 3, are reciprocated along guide bars 27, Fig. 6, by a cable 31, Fig. 3. In operation, a cord web to be cut is fed by belts 12a to 12d over a grooved cutter bar and beneath the blades until a sufficient length of material has been measured. Feed is then stopped and a cylinder 67, Fig. 6, is actuated to cause a thrust plate 69 to move the spindles 44, 44<SP>1</SP> axially downwards so that the points 60 of the blades pass through the cord web and enter the groove in the cutter bar. The carriages 29, 30 are then separated to cause the blades to cut the web. As the blades near the edges of the web, spring-loaded rollers carried by the carriages depress spring-loaded arms 90, Fig. 3, to cause pads 91 thereon to clamp the web edges whilst cutting is completed. After cutting and still during the blade separating movement, rollers 65 carried by the blade carriers 55, 55<SP>1</SP> are raised by running along arms 95 so that the blades are lifted to their original positions before they are returned to their starting position. Whilst in their separated positions, the blades are heated by inserting them between spring-loaded electrically heated plates (97, 98), Fig. 4 (not shown). The spindles 44, 44<SP>1</SP> are held in their raised or lowered positions by spring-loaded detents 53, Fig. 6. The angle at which the web is cut may be varied.

Title: Improvements in the manufacture of enamelled and glazed products
IPC: C03C4/00
Filed: 1937-08-27
Abstract: 501,210. Enamels and glazes. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 27, 1937, No. 23518. [Class 56] The mechanical stability, especially resistance to cracking, of enamelled and glazed surfaces formed by heating mineral materials to a high temperature, is improved by embedding chemically and thermally resistant metallic or mica spangles in the enamel or glaze. The spangles are of small dimensions of length and breadth e.g. a length of 1 mm. or less or a surface of 1 sq. mm. or less and of very small thickness, e.g. À1 to À001 mm. The spangles may be for example of mica heat resisting steel and alloys, nickel, copper orsilver and the surface may be silvered or chromed. When mica is used it is advantageously preheated to redness to eliminate water. The spangles may be added to glaze or enamel composition or may be applied before or after a heating treatment to the enamelled or glazed surface. A new layer of enamel or glaze may then be applied and the whole refined. A. layer of mica finally applied produces a silvery appearance and a high resistance to acids and alkalies. In an example fine silver plated copper spangles are mixed with a glazing slip or powder, the raw mass is coated with the glaze and fired in the usual manner. The quantity of spangles is 5-20 per cent of the weight of the glaze.

Title: Improvements in methods for the formation on the surface of metal articles of a layer of an alloy of the metal of said articles with at least one addition metal
IPC: C23C10/12
Filed: 1953-04-27
Abstract: 778,745. Coating with metals. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES, (O.N.E.R.A.). April 27, 1953 [March 12 1953], No. 23554/55. Divided out of 775,295. Class 82(2) In a semi-contact halide diffusion process the heating of the article and the regeneration reserve is controlled to prevent halide condensation it. The semi-contact method is that method where the halide source is out of contact with the article to be treated but in the same treatment container and the article is surrounded by, and in contact with, particles of the coating metal. The article and regeneration reserve are preheated by heat supplied outside the container so that the temperature of their coldest part is at least 100‹C. and preferably 150‹C. above the temperature of the portion of the container where the halide source is located. In Fig. 1 the articles P and regeneration metal (chromium) R are disposed together with the halide source C separated therefrom by a layer of lumps of chromium 6. Preheating is effected with the container in the position shown in pecked lines. A hydrogen atmosphere is maintained around the container. In Fig. 3 the heating means is an electric tunnel furnace and the preheating position of the furnace is again shown in pecked lines. After treatment the container is removed quickly into a cooling section 12. To prevent the articles &c. from sticking together, the tube 7 of this furnace is rotated by a worm 11 and wheel 10 during treatment.

Title: A method of charging a gas-cooled high temperature nuclear reactor
IPC: G21C1/07
Filed: 1969-05-08
Abstract: 1,269,804. Fuelling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 8 May, 1969 [8 May, 1968], No. 23614/69. Heading G6C. A gas-cooled reactor having fuel elements in the form of balls has a core divided into seven compartments 1, 5, 6, 7, 8, 9, 10 by a cylindrical graphite wall 2 and radial graphite walls 4, the core being surrounded by a reflector 3. Each compartment has its own fuel element charging and discharging equipment (not shown), the balls passing through the compartment by gravity. The reactor is fuelled by a method which ensures that each fuel element of one type, i.e. fissile or fertile, spends the same total time in the core. In the case of fissile elements this also ensures uniform burn-up. This method comprises passing the balls consecutively through different compartments in a certain sequence. Thus the balls are introduced into compartments 5, 6, these compartments are emptied and then the balls are introduced into compartments 7, 8. The compartments 7, 8 are emptied and the balls are introduced into compartments 9, 10. Finally, the balls are passed through compartment 1. The method also results in a more uniform power density over the entire section of the core since the fuel elements passing through the central compartment 1 are somewhat exhausted and this reduces the neutron density at the core centre. In a modification (Fig. 2, not shown) for use where the fuel elements comprise a mixture of fissile elements and fertile elements, the reactor core is divided into eight compartments, viz. a central compartment surrounded by seven outer compartments. The fuelling method consists of passing the fuel elements successively through four of the outer compartments during which process the fissile elements become spent. The mixture is then classified on a weight basis to separate the fertile elements and new fissile elements are added to replace the spent fissile ones. The new mixture is passed consecutively through the three remaining outer compartments and finally through the central compartment so that all the fuel elements are now spent.

Title: Method and Apparatus for Continuously Producing Tubular Foamed Polyurethane Insulation
Inventor: DIJK JAN CORNELIS VAN
IPC: A47L15/44
Filed: 1968-05-17
Abstract: 1,176,906. Tubular foamed polyurethane. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 17 May, 1968, No. 23627/68. Heading B5A. A method of continuously producing tubular foamed polyurethane insulation comprises feeding a liquid foamed polyurethane-forming composition or its components to a rotary ring dispenser 11 mounted rotatably around a pipe 22 which is positioned coaxially within a flexible body formed from a plurality of overlapping sheets of paper 24, rotating the dispenser 11 around the pipe so that the liquid composition is discharged centrifugally from the dispenser as a spray on to the inner face of the flexible tubular body, while at the same time the dispenser and the tubular body are continuously movable relative to each other, allowing the liquid on the tubular body to foam and thereby expand radially to fill the space between the pipe and tubular body whilst supporting the tubular body at its outer face by means of a frusto-conical body 18 and calibration disc 21, and allowing the foamed polyurethane to harden to form a tubular body 25. To prevent sticking, the pipe 22 may be coated with polypropylene. To form an insulated pipe both the pipe 22 and flexible tubular body made up of sheets of paper 24 are moved together while the dispenser remains stationary. However to insulate a pipe in the field the dispenser together with the rest of the apparatus is moved over the pipe. To form tubular sections of insulation material only the flexible tubular body is moved, the pipe and dispenser remaining stationary and the tubular insulation formed is cut into sections by circular saws.
