[Also in Division C3] The working walls of a continuous casting mould are degreased, e.g. by acetone or ethyl alcohol, and then coated with a lubricant coating composed of a polymer base, e.g. an epoxy resin, with the addition of molybdenum disulphide. The lubricant coating is prepared by adding and mixing 15 to 30 parts by weight of dibutyl phthalate into 80 to 150 parts of heated epoxy resin to which is further added 50 to 100 parts of molybdenum disulphide and 15 to 30 parts of polyethylene-polyamine. The mixture is then dissolved in a nitric solvent until it is suitable for applying to the walls of the mould. After application the drying period is not less than one day. After completing two or three castings the walls are washed with kerosene, dried and the lubricant coating is applied again.

Title: Thermal gas flow comparator
IPC: B64D45/00
Filed: 1965-01-22
Abstract: 1,094,412. Measuring pressure electrically. CSF. -COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 22, 1965 [Jan. 27, 1964], No. 3032/65. Heading G1N. The direction of gas flow towards a surface S, Fig. 3, determines the pressures in three ducts 1, 2 and 3, leading from the surface S into a chamber D in which are situated heated thermistors 21, 22, and the difference in cooling of the two thermistors produced by the difference in pressures between ducts 1 and 2 is a measure of the said angle of flow. The two thermistors are connected in two arms of a first bridge Fig. 2 (not shown) the other two arms being resistors (51, 52), and the supply voltage to the bridge is derived from a second bridge of which the first bridge forms one arm. The other three arms of the second bridge are resistors (70, 71, 72) and its supply voltage is derived from an A. C. source (4) via a transformer (75). A difference in thermistor temperatures gives rise to an error voltage in the first bridge, which is indicated (at 6) or used to control for example the orientation of an aircraft of which the surface S forms a part. A change in the total resistance of the two thermistors gives rise to an error voltage (at 76) in the second bridge, and this error signal is used to modify (at 73) the A. C. supplied to the second bridge, and hence to vary the excitation of the first bridge in order to increase its sensitivity. The thermistors are partly surrounded by housings 24 to reduce inaccuracies due to turbulence in the gas inside the chamber. An embodiment Fig. 1 (not shown) having only two ducts is disclosed, and more than three ducts may also be used.

Title: Self-energising disc brakes

Filed: 1973-01-20
Abstract: 1443320 Disc brakes GIRLING Ltd 18 Jan 1974 [20 Jan 1973] 3075/73 Heading F2E In a disc brake in which rotatable friction discs are brought into engagement with opposed radial surfaces in a stationary housing by the rotation in relatively opposite directions of pressure plates located between the discs, balls being located in co-operating inclined recesses in the adjacent faces of the pressure plates, the rotational movement of the pressure plates is effected mechanically by a pair of toggle links connected between radially projecting lugs on the plates, a pull-rod 1 being connected to the junction of the links; an abutment 10 on the pull-rod 1 is acted on by the movable member (e.g. the piston 3) of a piston-cylinder hydraulic actuator through a pivotal thrust coupling which allows movement of the rod 1 relative to the movable member in one plane only, the actuator being disposed substantially at right angles to the axis of the brake. As shown in Figs. 1, 2, the abutment 10 in the form of a rectangular block is provided with transverse trunnion pins 13 the ends of which are pivotally received in part-cylindrical grooves 14 in outward extensions of the piston 3 so that the rod 1 can rock about the piston 3 in a single plane. The piston 3 is keyed against angular movement a locating plate 17 is clamped between a cover 16 and a fixed cylinder body 5 which plate 17 has diametrically opposed tongues 19 projecting inwardly from a circular opening (18) for sliding engagement in a straightsided slot 21 which extends diametrically through the piston 3 and also accommodates the abutment 10. The tongues 19 form a stop for the piston 3. A nylon ring 22 has partcylindrical recesses to complete a bearing for the trunnion pins 13. The block 10 may be adjusted on the rod 1 by rotating a nut 11 after slackening a lock nut 12, a washer formed with arms 24 which grip nut 11 allowing of click-stop incremental adjustment. In the embodiment of Fig. 4 (not shown) a thrust member (25) interposed between the piston (3) and the trunnion pins (13) receives the trunnion pins (13) and is keyed to the cylinder by the tongues (19) engaging in a slot (26) of the thrust member (25). In the embodiment of Fig. 5 the block 10 is of generally spherical shape and the thrust member 25 has opposed grooves 28 extending axially to key it to plate 17. The coupling between the pull-rod and the movable actuator member could be formed by a pin and clevis arrangement. When the pressure plates are rotated to initiate brake application the pressure plates are carried round with the friction discs until one is arrested by the engagement of a lug on the plate with a stop in the housing and the continued angular movement of the other pressure plate provides a servo action. The pivotal thrust coupling being keyed directly or indirectly to the fixed actuator member (e.g. cylinder body) maintains the pivotal axis of the coupling substantial parallel to the brake axis whereby the plane to which rocking movement of the rod is confined is substantially normal to the brake axis.

Coating - machines. - Paper &c. tubes which are formed by spiral winding around a mandrel are coated internally with water-resisting or other material, e.g. varnish or paraffin wax, by means of a brush, spraying device, &c., attached to the mandrel through which the coating material is fed. As shown, the mandrel a is fitted with a pipe b fed from a raised tank with a. suitable coating-medium, which is kept warm by means of a steam pipe d, or by an electric coil, or by heating the raised tank. The liquid may pass direct on to a brush f attached to the mandrel a, or, as shown, a sprayer g may be employed to direct an oblique spray over the interior surface of the finished tube, the brush f being dispensed with in some cases when the width of the spray is greater than the pitch of the tube. The brush f is also greater than this pitch. Gaseous pressure is employed for delivering the coating medium. The spray producer may comprise an annular space h into which liquid passes from the tube b, and helical grooves i then give it a whirling motion, and spray is formed by striking against the front of the nozzle before leaving by a jet j controlled by a taper-pin.
