Patent GB-1450363-A (GB)
Title: Frangible valved fitting
IPC: F16K17/40
Filed: 1975-02-07
Abstract: 1450363 Pipe couplings AEROQUIP AG 7 Feb 1975 [11 Feb 1974] 5351/75 Heading F2G A valved coupling comprises in combination, a valve body 10 having a passage 12 providing a fluid flow path therethrough, means frangibly connecting the valve body to a conduit (in Fig. 1 the conduit is a second valve body) a flapper valve 44 within the passage 12 and pivotally mounted at 46, a valve seat 42 within the passage 12 to co-operate with the valve 44 in its closed position to close the passage, and retaining means, e.g. ring 56 having lip 60, within the passage to releasably retain the valve 44 in its open position. The coupling includes means operating the valve 44 by sensing connection of the body 10 to the conduit, fracturing of the frangible connection causing operation of the retaining means to release the valve 44 in order to close the passage 12. The valve 44 may be pivoted on a ring 32 which is slidably mounted within the passage 12 and biased away from the retainer ring 56 by a compression spring 62. However, in the valve open position the ring 32 is held against the force of the spring 62 by axially extending pins 98 received in recesses 100 in the ring 32 and in corresponding recesses in the conduit. In this position a lip 54 on the valve 44 engages the lip 60 on the retainer ring 56, to hold the valve open. The frangible connection comprises radially disposed frangible pins 88 located such that they fracture on applying axial shear forces and/or axially disposed frangible bolts or rivets 92 located such that they fracture on applying transverse shear forces. On such fracture, movement of the body 10 away from the conduit in an axial or transverse direction causes the pins 98 to fall from their recesses, thus allowing ring 32 to be pushed away from the retaining ring 56 with consequent closure of the valve 44.

Abstract: 267,910. Siemens & Halske Akt.- Ges. March 20, 1926, [Convention date]. Resistances, measuring.-An instrument for measuring insulation resistance or other resistances has mounted on its spindle a current coil 4 and two oppositely wound pressure coils 2, 3, the torques due to the pressure coils approximately cancelling one another in the position shown, which corresponds to an infinite resistance. The coil 2 is mounted inside the coil 3, and is slightly greater in internal diameter than the central iron core 1, which is supported by thin plates 5 ,6. The moving system 2, 3, 4 is enclosed by the magnets 9, 10 and pole-pieces 11, 12, in order to eliminate the influence of external fields. Mounted on the pole-pieces 11, 12 are horns 13, 14 whichenter between the coils 2, 3 in their zero position as shown in Fig. 2, which is a section on the line A-B, Fig. 1. A U-shape magnetic shunt 15 is arranged outside the coil 3. At the horns 13, 14 the flux divides, one part passing through the core 1 and cutting the coil 2. and the other part passing through the shunt 15 and cutting the coil 3, the flux thus cutting the coils 2. 3 in opposite directions. Since the currents in these coils are in opposite directions, the torques due to them are in the same direction near the zero position, so that the scale divisions are close together towards the zero end and spaced apart towards the infinity position.

As shown, the shield is built into the upper portion 1a of the dam and is provided on both sides with ribs 2 connected by haunches 3, Fig. 1, to the shield 1 the ribs being staggered on opposite sides. The ribs 2 may slope inwardly towards the base which is mounted on a footing 10 so that rotational and tilting movement may take place. The sections forming the shield are connected together at spaced vertical positions by reinforced concrete keying blocks 9 loosely inserted in recesses 8 in the ends of the sections, the positions between the blocks being connected by a loose tongue 7 and groove 6, the sections being bevelled at 7a to allow for slight rotation of the joint. If a control gallery is provided the shield may rest directly on the gallery instead of on the footing 10. In a modification the walls of the shield and ribs are corrugated to allow optimum contact between the walls and the earth and rubble of the dam. In a further form the shield is inclined with its upper surface nearer the open side of the dam.

IPC: C08G14/08
Filed: 1945-03-08
Abstract: Artificial resinous substances are prepared by condensing in the presence of a catalyst an aldehyde or a substance which yields an aldehyde under the conditions of the reaction with a mixture of urea, thiocarbanilide and a phenol.  Suitable catalysts are an acid, e.g. hydrochloric acid, an alkali, e.g. ammonia or an alkali metal hydroxide, or a thiocyanate, preferably ammonium thiocyanate.  The reaction proceeds in the cold, but is accelerated by heating.  A solvent for the reacting substance may be present.  Products are thermosetting and may be used for lacquers or, mixed with fillers, for moulding powders.  In the example, an aqueous solution of urea is mixed with thiocarbanilide and m-cresol.  While stirring, formaldehyde and lactic acid are added and the mixture is boiled under reflux with constant agitation for 6-8 hours.
