    Abstract: 1,220,088. Logic circuits: circui's employing bi-stable magnetic elements and cryotrons. J. H. CASE and N. C. STEWART 28 Dec., 1967 [29 Dec., 1966], No. 58929/67 Headings H3B and H3T. [Also in Division G4] Figs. 3, 5, 6 show respectively magnetic core (or thin films may be used), cryotron, and transistor versions of a circuit which is set into a first or second state by a pulse at α 1 or α 2 respectively. When in the first state, any pulse at A 1 will be passed to B 1 but any pulse at A 2 will be blocked, whereas when in the second state, any pulse at A 2 will be passed to B 2 but any pulse at A 1 will be blocked. Power (clock) pulses are provided at the inputs P as shown. For greater fan-in, fan-out, a circuit with the above properties can be constructed from a plurality of the above circuits, most of which have A 1 and A 2 connected together and B 1 and B 2 connected together to form an isolation and delay circuit (Fig. 2c, not shown).

    Abstract: The lid has an upper surface 20 and a lower surface, and an exhaust aperture 32 through the lid extending from the lower surface to the upper surface. A solar-powered extractor fan 34 is mounted in the exhaust aperture. The lid is especially suitable for a waste material container 12 in the form of a wheelie bin (10, figure 1). The extractor fan generates a flow of air through the waste material container when exposed to sufficient light conditions, to reduce the internal temperature thereof thereby reducing the rate of decomposition of waste material therein. An inlet aperture 38 containing an air conditioning agent, may be provided, said agent comprising a liquid or solid fragrance device, deodorant or insecticide. The lid may be retro-fitted to existing containers.
