Cut-out arrangements.- Overload relays associated with each of the parallel connected generators 100, 200, 300 cause a limiting resistance to be inserted in each generator circuit when any one generator is overloaded. Assuming the generator 100 is running, switch 170 and relay contacts 181 will be closed, thereby energizing coil 110 from control supply 10, 11. Contactor 111, 112 will be closed and also auxiliary contacts 113, which complete a circuit through the overload relay contacts 121, 131, and the overload relay contacts of all the other machines to coil 190, thereby closing contacts 191 so as to energize coil 160 and cause contactors 161, 162 to shunt the resistances 140, 150. Upon an overload on any machine, the contacts 191, and the corresponding ones of the other machines are opened, and thereupon the limiting resistances 140, 150 are inserted in circuit with the generator 100, and corresponding resistances are inserted in the circuits of the other generators. All the limiting resistances remain in circuit until all the overload relay contacts have again closed. Reference has been directed by the Comptroller to Specification 270,043.

Title: Integrated circuits method of and apparatus for repainring the lining of coke-oven
IPC: H01L27/04
Filed: 1974-04-05
Abstract: 1444193 Integrated circuits HUGHES AIRCRAFT CO 5 April 1974 [30 April 1973] 15166/74 Heading H1K In the manufacture of an integrated circuit access is maintained to every contact pad of each circuit component on the wafer, regardless of the components' operability or inoperability, up to a third level of metallization. The total wafer function is tested at the third metallization level and if a fault is found diagnostic testing is carried out to determine the cause(s). Wire bonding between pads at the third metallization level then enables repairs to be effected, replacing faulty components and connectors by unused operable alternatives. Figs. 3a-3e show corresponding portions of the three metallization levels (3a, 3c, 3e) for a circuit, with the lead-through patterns (3b, 3d) interconnecting the levels. At the first metallization level (Fig. 3a) each circuit component is tested and a yield map is obtained. A master pattern is devised, determining circuit locations for the components required to achieve the circuit function in such a way that each determined location is surrounded by at least three relocation candidates and so that inter-component line lengths are minimized. Fig. 3b shows the lead-through pattern through an insulating layer overlying the first metallization level and permitting access to each first level contact pad 24a at the second metallization level (Fig. 3c). The second level includes the necessary lines such as 42 to relocate operable circuit components in the predetermined master pattern locations where the yield map shows the original components to be inoperable, and lines 50 to slightly alter the locations of the contact pads in operable correctly-located components. Fig. 3d shows the lead-through pattern through a further insulating layer overlying the second metallization pattern, providing access to all pads in the second level, both in their original and relocated positions. The third metallization level (Fig. 3e) provides interconnection between all selected operable circuits in their predetermined master pattern locations. After wafer function and diagnostic testing the necessary repairs are carried out by wire bonding and connection-breakage as necessary, sufficient redundancy being maintained to this level by the provision of access to all lower level pads. If a fault arises from bad design, or if a minor change is required in the wafer function, all the unused operable circuit components are accessible at the third level to facilitate this.

[Also in Divisions F2 and G1] The cooling of an air-cooled I.C. engine is controlled by a rod-type thermostat 1 arranged alongside a complete row of cylinders. As the temperature of all the cylinders increases, the differential expansion of tube 4 with respect to rod 5 causes the transmission lever 9 to move sliding member 10 against the action of spring 13, to cause admission of engine oil from conduit 14 through conduit 15 into an hydraulic coupling engaged in driving the cooling fan. As the coupling slip decreases the cooling fan speed increases to give cooling air flow. Oil leaking round sliding member 10 flows through holes 16, along spring 13 and through conduit 17 to the engine. In another embodiment, the thermostat 1 actuates a link controlling flaps situated in a cooling air outlet passage to control the cooling air exit flow and to by-pass some exit air through the surrounding engine casing to the cooling fan inlet. The thermostat may be arranged to mechanically actuate a cooling fan clutch or may actuate a control changeover switch for the electric motor of a cooling fan. The control valve may control the supply of compressed air to a pneumatic coupling driving the cooling fan. Any rod-type thermometer using the differential expansion of two substances e.g. metals or liquids, may be used.
