Abstract: 1438134 Lamps SIEMENS AG 21 Sept 1973 [25 Sept 1972] 44356/73 Heading F4R [Also in Divisions H2 and G4] A lighting system comprises a tungstenhalogen incandescent lamp 1 provided with two filaments 2, 3 and a timing device 7 which enables the filaments to be periodically and alternately supplied with current. The lamp may be a red stop lamp in a traffic signal installation. The timing device 7 controls the positions of contacts 8 1 , 8 2  of a switch 8 and a monitory device 5 checks that the lamp lights up correctly. On closure of a switch 4 the filament 2 is energized, assuming that the timer 7 has set the contacts 8 1 , 8 2  in their indicated positions. If the filament 2 becomes broken, a monitoring device 6 changes over contacts 6 1 , 6 2  to energize the filament 3 and prevent operation of the timing device 7. The switches may comprise transistors and the timing device ensures equal energization times for the two filaments thereby preventing one of the filaments being destroyed due to its not being energized.

[Also in Division H3] A logic circuit suitable for use in an " adder " comprises a device with two alternative adjustable thresholds and which conducts when the operative threshold is overcome by input signals, the higher threshold being rendered effective in accordance with the condition of restraining signals. In Fig. 1a, transistor T 1  is normally biased into a conductive state by resistor chain R 4  and may be cut off by simultaneously applying a predetermined number of inputs e r , the number of inputs required being determined by a threshold set by a resistor chain R 4 , and being variable by bridging resistors of the chain. A normally non-conductive PNP transistor T 2  has its emitter-collector path connected in parallel with the chain R 4 , and when switched on by a predetermined number of restraining inputs H, increases the threshold of T 1  so that a larger number of e r  inputs are required to cut T 1  off. The conductivity threshold of T 2  is determined by an adjustable resistor chain R 2 . In a modification, Fig. 1b, transistor T 2  is normally conducting NPN transistor, and has its collector taken to a potential U 3  via an adjustable resistor chain R 6 , the bias threshold on T 1  still being modified by changing the state of T 2 . If e r  inputs are coupled to the restraining (h s ) inputs, a number of logical circuits may be produced including a full adder (Fig. 7) which comprises a first stage having lower and upper thresholds of 0 and 2 inputs respectively which produces the sum output and a second stage having a single threshold of 1 which produces the carry output. The restraining stage which changes the threshold of the first is arranged to have a threshold of 2.

[Class 23] A centrifugal machine of the amalgamating type has means for supplying pulp to the base of the bowl, from which it travels upwards over a mercury lining the surface of which is rippled by a mesh lining forming a number of pockets. The apparatus is supported in a frame 2, and the bowl 9 has a base 11 with a diverging wall section 12 rising from it. An impeller 27 is secured to the bottom of the feed pipe 19 which is supported in a bearing 20 and rotated from the shaft 23.
