Class 47 A gas leakage or discharge indicator for a CO 2  type fire extinguisher comprises a piston 3 including a cupped washer 4 operating in a bore between a gas inlet 17 and a gas outlet 7 to constitute a valve which by its displacement to an open position under influence of gas pressure gives an indication of gas leakage or discharge, and a shoulder 10 formed on the bore against which the washer 4 makes a seal when forced into the open position, thereby preventing escape of gas past an extension 6 carried by the piston which serves to project from the cap 12 to give a visible indication of gas leakage or discharge. The extension 6 may be pointed and arranged to pierce a disc fitted to the cap 12. A bore 13 communicates with a safety valve so that operation of the safety valve also operates the piston 3. When the piston 3 is displaced a spring ring 16 enters a neck 11 in the extension to prevent the piston from being pushed back until the cap 12 is removed with a special key. The bore is tapered to ensure correct re-entry of the piston into its initial position. Specification 747,631 is referred to.

Abstract: 1,125,058. Integrated circuits. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1967, No. 36327/67. Heading H3T. An integrated circuit comprising a number of units 22. 23, 24 has associated with. each unit an output transistor T1, T2, T3 whose emitter is connected to an output terminal 26, 29, 30 and via a resistor R1, R2, R3 to an electronic switch S1, S2, S3 shown as a diode. When a voltage is applied to line 27 such as to make the diodes conductive the transistors operate as separate emitter followers and can be used to drive short transmission lines which do not have to be terminated in their characteristic impedances. If the diodes are biassed off, the emitter resistors are isolated and the transistors can be used to drive long matched lines. Similarly, if the outputs of several circuits are to be paralleled and only one emitter resistor is needed, the resistors in the other circuits are isolated by biassing off the corresponding diodes. The diodes may be replaced by transistors (Fig. 3, not shown).

Abstract: 1469452 Packing articles with relatively movable internal and external components PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 March 1974 37147/74 Divided out of 1469451 Heading B8C A composite article having an external component and a relatively freely floating internal component is packed for transport by coupling the internal component rigidly to the external component by a connecting means such as a threaded rod. The connecting means passes through a hole in the outer component and is located in the horizontal plane containing the centre of gravity of the internal component. After transport the internal component is released merely by removal of the connecting means. Removal is effected from the outside the external means and the method involves no packing pieces to be left inadvertently inside the article. In a preferred embodiment, a washing machine comprises a cabinet 1 containing a suspended internal unit (not shown). The rear wall of the cabinet is provided with a pair of holes in which are located self-sealing bushes 4. A pair of threaded rods 8 are pushed through the bushes and screwed into threaded apertures in the unit after which the whole assembly is tilted to bring the unit into contact with the rear wall 3 of the cabinet. A rear brace pad 5 of cardboard and a rear brace 7 of chipboard are applied over the protruding ends of the rods and an adhesive applied to these ends. Washers 10 and nuts 11 are then applied and the nuts tightened against the rear brace to maintain the unit in firm contact with the rear wall of the cabinet. If desired the front region of the unit may be similarly secured using a pair of braces 14, 15, rods 16, 17 and wood spacers 18. When it is desired to release the unit a spanner is applied to the nuts, which now form a bolt-like construction with the rods, this causing withdrawal of the rods and freeing the unit. Such a working machine may be stood on a base support not shown, sandwiched between edge 24 and side 27 protectors, covered by a buffer 28, strapped and then placed in an external box. Edge protectors 24 are recessed at 25 to receive the access panel 26 which will close the side opening 12 through which the front region of the internal unit is secured during transport. Instead of using an adhesive, the nut may be coupled to the threaded rod to form a bolt using a locking unit.
