Title: Receiver tuning arrangements
IPC: H03J5/02
Filed: 1971-09-14
Abstract: 1326843 Receiver tuning; multistate circuits; touch responsive switching systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Oct 1971 [10 Oct 1970] 46775/71 Headings H3B H3Q and H3T [Also in Division G4] A receiver tuning arrangement has bi-stable trigger circuits each including a four layer semiconductor device 10 having a cathode, cathode gate, anode gate and anode and an electrical locking arrangement 14 is coupled to all the bistable circuits 10 so as to bring all other bistable circuits 10 previously in an operating condition to a rest condition on changeover of one of the bi-stable circuits 10 from the rest condition to the operating condition when its associated signalling device 2 is operated. An adjustable potentiometer 20 is associated with and coupled with each bi-stable circuit 10 so that a potentiometer is connected across a supply + Vs only when the associated bi-stable circuit is in its operating condition and the potentiometers are connected to a common lead for applying a tuning voltage to one or more electronically controllable reactances 23. As a result of capacitor 27 when the tuning arrangement is switched on transistors 4 and 7 conduct and turn on the four layer device 10. An indicator lamp 16 is switched on and the potentiometer 20 is switched across the stabilized supply + Vs so that the tuning voltage set by this potentiometer is fed via a diode 21 to variable capacity diodes 23. Manual tuning by this potentiometer is obtained by a knob 25 and is indicated by a scale 26. When the signalling device 2 in the operating unit 1a is touched the associated transistors 4 and 7 conduct and cause a transistor part 10a of the four layer device 10 in the unit la to conduct. The transistor part 10b starts to conduct and maintains the transistor part 10a conducting also when the signalling device 2 is subsequently released. The switching on of the four layer device 10 in the unit 1a lights indicator lamp 16 and switches in the potentiometer 20 to provide a tuning voltage via the diode 21 in unit la. When the four layer device 10 in the unit 1a conducts its anode, as represented by the emitter of the transistor part 10b, becomes substantially ground potential and as the capacitor 12 of the unit la is initially uncharged the potential on lead 13 also decreases to ground potential. Since the capacitor 12 of the unit 1c which had been operating is charged the emitter voltage of transistor part 10b of unit 1c decreases below ground so that the four layer device 10 of this unit 10c is cut off. In a modification (Fig. 1, not shown) the output of the four layer device 10 may be used to switch an associated transistor (18) connected in series with the potentiometer 20. The resistor 15 serves to protect the four layer device 10 in ease a short circuit occurs in the indicator 16 and resistor 3 prevents too high base-emitter current in the transistor 4 if the conductors of the signalling device 2 are short circuited.

A light-sensitive material of wide sensitivity comprises a support bearing three superposed colour forming layer units each containing a different colour coupler and comprising at least one silver halide emulsion layer sensitive throughout the range 400 to 700 mÁ and having an exposure range greater than 1 log E unit with a bleachable neutral density layer of density greater than 0.5 located between at least two of the colour-forming layer units, the layers being so arranged that the effective sensitivity of each layer to light incident on the surface furthest from the support decreases towards the support. The decreasing sensitivity can result from the initial sensitivity of each layer and/or the effect of the neutral density layer(s). As shown in Fig. 1 each layer unit may comprise a fast and a slow layer and in Fig. 2 (not shown) the colour order of Fig. 1 is reversed with a neutral density layer between each colour unit. The material may have an exposure latitude above 5 log E units and after severe exposures can give a readable record on filtering out the colours of the overexposed layer(s).

An autoclave for treating asbestos-cement sheets carried in trucks in the autoclave, comprises externally at least two peripherally mounted rolling rings supported on rollers with a toothed sector for rotating the autoclave through 90 degrees while inside the autoclave there are supports for the sheets and trucks which hold them when the autoclave is tilted through 90 degrees. In a specific embodiment, Figs. 1 and 2, trucks 9 loaded with asbestoscement sheets P are rolled into the autoclave from the runway C on to rails 8. The lid I is placed on the autoclave and steam delivered thereto to effect a hardening process. The autoclave is rotated through 90 degrees by means of motor M acting on gear wheel 7 and sector 6, the rolling rings 2 being held by pairs of rollers 3 which are mounted on bearers 4. The bearers 4 are mounted on rollers 5 which allow for expansion of the autoclave. When the autoclave is tilted through 90 degrees, abutment 12 and planar support 13 hold the asbestos sheets P while the truck 9 with its metal plate 10 are held by check rail 11 and blocks 14 and 15 respectively, thus the plates splay out when in the vertical position and allow free circulation of steam around them. The autoclave is then drained and righted.
