Zones of different temperatures and oxygen concentrations form at different levels in the reactor, the highest oxygen concentration being near the bottom and the highest temperature being near the top where there is preferably a sanitizing "heat-trap zone" of 70-80‹ C. The location and biological activity of the zones may be monitored by temperature and gas probes (to measure O 2  and CO 2  concentrations), and controlled by adjusting the sludge or air/O 2  feed rates. The sludge feed may be sprayed with water and seeded with bacteria at the top of the reactor, and takes 14-20 days to reach the bottom. The air may be fed to the reactor through small-diameter nozzles.

Abstract: 1,090,970. Coated sheet material. SOMMER S.A. Dec. 17, 1964 [Dec. 26, 1963], No. 51338/ 64. Heading B2E. [Also in Division B6] A method of embossing a polyvinyl chloride coating on a support web, e.g. tagged jute felt, comprises embossing an uncured polyvinyl chloride layer at ambient temperature and, by means of heated rolls, developing simultaneously with the embossing steps a pre-gelatinized film on the uncured layer wherein the embossing steps and steps comprising filling cavities formed by the embossing steps with further layers of polyvinyl chloride of different colours are carried out successively and alternately and whereafter a single curing step is applied to the product. The successive and alternate embossing and filling steps may be effected by means of embossing rolls and doctors respectively, located above a cylinder of large diameter for guiding the coating and the support web in a controlled manner during the operation of the embossing rolls and scrapers for effecting the "embossing in exact ratio". Before the curing step the polyvinyl chloride coating may be subjected to an additional embossing step for breaking at random the repetition effect of the patterns formed by the successive and alternate embossing and filling steps. Apparatus for carrying out the method includes rotary heated embossing rolls heated to a temperature approximately 180C and doctors for coating layers of fillers wherein the rolls and doctors are disposed successively and alternately before the apparatus for curing the polyvinyl chloride. The apparatus may have at least one rotary drum of large diameter which guides the polyvinyl chloride coated web under a series of rotary heated embossing rolls and coating doctors for effecting the embossing in exact ratio of the polyvinyl chloride before the apparatus for curing the polyvinyl chloride. The rotary heated embossing roll may be arranged just before the apparatus for curing the polyvinyl chloride and is adapted to break at random the repetition effect of the patterns formed on the polyvinyl chloride layer. As shown, support 1 passes under doctor 21 to receive a polyvinyl chloride plastisol, and moves between rotary embossing roll 2 at a temperature of about 180C and counter-roll 3, under doctor 4 which spreads a second layer of polyvinyl chloride, and around large-diameter rotary drum 5 which acts as a counter-cylinder to rotary embossing rolls 6, 7, at a temperature of about 180C, between which doctor 8 is arranged to deposit a third polyvinyl chloride layer of another colour, under doctor 9 which spreads a further plastisol layer of a different colour, under embossing roll 10 at a temperature of about 180C which "breaks" the regular repetition of the patterns previously formed, around heating drums 11 to gel the polyvinyl chloride coating, under fine-embossed cold roll 13, over cooling drums 14 and is finally wound upon drum 15.

[Also in Division G4] Circuit for selectively applying a voltage to one or other of two pairs of output terminals through a step-up transformer includes an arrangement whereby the supply to the transformer is first cut off, and the changeover of the output is made before the voltage in the transformer secondary has built up to its normal value. In the circuit shown, two discharge lamps 20, 21, which may form part of a pedestrian crossing control system, are connected respectively to pairs of output terminals 17, 18 and 17, 19. In the condition shown, mains voltage is applied to terminals 15, 16, energizing the transformer 11 by way of contacts A1, B1, and operating the lamp 20. On a signal from a control device A, the switch A1 opens, breaking the circuit to the transformer, and, after a predetermined time lag, closes in its make position to energize a relay B. Contact B1 is now moved from its break to its make position, restoring the supply to the transformer primary 12, and at the same time a switch B2 is also moved to connect the lamp 21 across the transformer secondary 13. The transformer 11 is of the high-reactance type to ensure that the secondary voltage is always low when the switch B2 closes.

In a semi-conductor device in which the emergence of a junction at a major face of the wafer is covered with an insulating passivation layer, leakage across the junction due to the formation of an inversion layer is reduced by applying a conductive layer over the insulating layer and conductively connecting this layer to an electrode applied to one of the regions forming the junction. As shown, Fig. 4, a unipolar transistor is produced in an N-type wafer 28 by diffusing-in P-type region 30 and N<SP>+</SP> type regions 32, 33. A layer 40 of silicon dioxide is formed over the surface and windows are formed for electrodes, 34, 35, and 36 which are produced by evaporating a metal layer on to the oxide and alloying to the exposed regions. Drain electrode 35 has an extension 37 over layer 40 which covers the junctions 29, 31 where they emerge to reduce surface leakage currents caused by the formation of an inversion layer. Region 33 connects gate region 32 to the substrate 28 to which the gate electrode 36 is applied. Conductive layer 37 may be of aluminium, or, if the layer is also to protect the junctions against radiation, it may be of lead deposited over an aluminium or nickel contact. In an NPN bipolar transistor, Fig. 5 (not shown), the emitter junction is covered by a conductive extension of the emitter electrode superposed on an insulating passivation layer. The invention may also be applied to diodes and components such as capacitors and resistors formed as parts of an integrated circuit. The semi-conductor material may be silicon and lead oxide is mentioned as another passivation material. Reference has been directed by the Comptroller to Specification 998,388.
