Abstract: 1404488 Conducting liquid switches; cell with circuit completed by water DYNAMIT NOBEL AG 1 Dec 1972 [2 Dec 1971] 55733/72 Headings H1B and H1N In an electric switch in which water, such as sea-water, acts as the conductor, a rupturable diaphragm 14, Fig. 2, normally prevents ingress of water to engage a contact 6 in a chamber 16 to complete a circuit. The switch is used in conjunction with a voltaic cell 17 mounted in an insulating housing 5. One end of the cell 17 is permanently in engagement with a spring loaded terminal end 9 and the other with the fixed contact 6. The diaphragm 14 is pierced by a spring loaded pin 4 when released by manually withdrawing a locking pin 13. A conductive cap 1 forms the other terminal contact of the switch, and has passages 15, through which the water flows to the diaphragm 14. The switch is used in conjunction with an eletronic time delay circuit, Fig. 3 (not shown), for sequentially operating marine distress signals (26, 27) which may have pyrotechnic charges.

Title: Fluid pressure operable brakes
IPC: F16D65/18
Filed: 1971-12-10
Abstract: 1309217 Brake actuators; slack-adjusting; disc brakes PONT-A-MOUSSON SA 10 Dec 1971 [12 Feb 1971] 57373/71 Heading F2E A fluid-pressure brake actuator comprises a cylinder 2, a piston 3 for carrying a brake lining 5, a member 9 of plate form constructed to return the piston by magnetic action, slidably disposed in the cylinder behind the piston and having a pressure-equalizing aperture 10, and a projection 7 extending from the back of the piston through the member 9 with limited axial play corresponding to the normal working stroke of the piston, whereby, when the normal stroke is exceeded as a result of lining wear, the piston entrains member 9 to adjust the working stroke.  As shown and described, the following forces or resistances are listed in decreasing order of magnitude: the force on the piston due to fluid pressure introduced at 6 for operation, the resistance of resilient seal 11, the magnetic attraction of member 9 on piston 3, and the resistance of piston seal 15. Member 9 is a permanent magnet. In operation, in the absence of wear, fluid pressure forces piston 3 away from magnet 9 through a distance a (see parts 1, 5 and 9, 13). On release, magnet 9 retracts piston 3 to its former position. On wear occurring, necessitating movement of piston 3 through distance b, the fluid pressure forces it first through distance a, after which the continuing fluid pressure causes the piston to entrain magnet 9 by means of split ring 13 and overcome the resistance of seal 11, moving the assembly a further distance (b-a). On release, seal 11 holds magnet 9 in its new position while the magnetic force withdraws piston 3 a distance a once more. In Fig. 2 (not shown) member 9 is an electromagnet fed from an external source. The fluid may be hydraulic or pneumatic. The invention is applicable also to drum brakes with appropriate change of shape of pad 5.

Abstract: 1,212,279. Integrated circuits; circuit assemblies. ITT INDUSTRIES Inc. 5 Dec., 1968 [6 Dec., 1967], No.57772/68. Headings H1K and H1R. To produce a multi-layer integrated circuit, semi-conductor dice 1a 16, 1d, 1e containing sub-circuits or individual devices are bonded together in a stack. The elements (devices or sub-circuits) in adjacent dice may differ. On each die the conductive tracks. from each element are led to one (or to opposite) edge(s) of the element, area and terminate in alignment with those of the other elements in the same row. When the dice are stacked these lines are arranged to be in planes 10, 10<SP>1</SP> perpendicular to the dice, and the stack is then divided along these planes to expose the end of the conductors and to form rows of individual integrated circuits joined side by side. The dice within the stack are bonded together by conductive or insulating layers as appropriate to. the circuit requirements-conductive layers may be of solder and contain an R.F. screen 13: insulating layers may be of glass or a polymer such as PTFE. Two methods are disclosed: in one, the rows of integrated circuits are rotated about their axis by- 90 degrees and rebonded by insulating layers to adjacent rows (.using a temporary or permanent binder), and then the various dice layers within each integrated circuit are interconnected by single-layer or multilayer edgemetallization. Individual circuits may then be separated by division in planes perpendicular to the dice planes- and to the original dividing planes. In the second method the dice of several circuits are stacked sequentially so that edge metallization can be effected immediately after the first division. With both methods, the edge metallization may be carried over to an end (major die) face of the circuit and individual circuits bonded side by side and the face metallization interconnected, by further deposition of metal to yield a more complex circuit An. embodiment given is a UHF-VHF tuner and the dice used respectively contain or carry transistors, varactor diodes of one and the other polarity, and non-semiconductor components such as resistors and inductances.
