Title: Circuit arrangement incorporating automatic gain control
IPC: H03G3/30
Filed: 1967-12-14
Abstract: 1,140,309. Transistor automatic gain control circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Dec., 1967 [17 Dec., 1966], No. 56792/67. Heading H3T. An a.g.c. arrangement comprises an amplifier incorporating two transistors T1, T2, connected as a long-tailed pair by means of resistor R2, in which a direct voltage is applied to the base of one of the transistors T1 while the base of the other transistor T2 receives a control voltage composed of a direct voltage and a signal dependent voltage. The direct voltage for the first transistor T1 is derived from a first emitter follower T5 whilst the control voltage for the other transistor T2 is derived from a second emitter follower T6 whose emitter circuit is decoupled, by capacitor C3, said second emitter follower T6 operating as a signal detector and the bases of the two emitter followers being connected to a common point K in the amplifier. The arrangement as described comprises an I.F. amplifier which may be constructed in integrated form, the demodulated output being taken from potentiometer RL in the emitter circuit of transistor T6, which is decoupled for signal frequencies only by means of capacitor C3. Transistor T5 is prevented from acting as a detector by means of the negative feedback produced by an undecoupled emitter circuit resistor R7, and both the emitter followers T5, T6 are driven from the collector circuit of transistor T1 via an amplifier comprising transistors T3, T4. The a.g.c. may be delayed by means of resistors R11, R12 in the emitter circuits of transistors T1, T2 respectively. The arrangement has inherent D.C. negative feedback which provides temperature stabilization.

Filed: 1971-12-08
Abstract: 1378499 Packaging eggs H NOGUCHI 8 Dec 1971 57127/71 Headings B8C and B8A In a packaging machine, eggs are oriented and are formed into a row which is placed in a container with the acute ends of the eggs downwards. Egg-aligning.-Eggs are supplied one at a time in random orientation to the inlet of a passage b leading to an exit passage b<SP>1</SP> via a further passage B. The eggs are carried though the passages by rollers 4 rotatably carried by driven endless chains, and contacting a fixed plate F so as to rotate as the chains are advanced. Each roller 4 has a recessed seat 4a at one end. If an egg is supplied to the passage B with its acute end e facing the seats 4a, the rotation of the rollers 4 causes the blunt end E to rotate faster than the acute end e thus causing the egg to slide towards the seats 4a for discharge from the passage b<SP>1</SP>. If, however, an egg is supplied with its blunt end E facing the seats 4a, rotation of the rollers 4 causes the egg to abut a side wall of the passage b, which side wall leads to an inclined wall 2 which causes the egg to pivot on its blunt end E so that the acute end e is raised and directed towards the seats 4a. Thus all the eggs leaving the passage b<SP>1</SP> have similar orientation. Row-formation.-The eggs are next pushed along an inclined guide 6 by pairs of rods 7a on an endless conveyer 7. Each egg abutting the operating lever of a microswitch 9 so as to advance belts 12 to position a saucer 13 for reception of the egg. When a predetermined number, e.g. five, of egg has been connected the microswitch causes a bar 10 to rotate to prevent further egg feed. Packaging the eggs.-A shaft 15 carrying pusher blades 16 is then rotated so that the blades 16 engage the blunt ends E of the eggs, the acute ends e being guided into recesses in a container 31 by guide plates (21, Figs. 11-13) carried by bars 19 lowered by cams 17 on the shaft 15. The container has two rows of recesses and is supported in a member 30 carried by endless chains 29 which are then advanced to position the second row below the guide plate (21). Filled containers are carried past a folding bar (39, Fig. 14) which folds a lid portion on to the container base for welding by a device (37). The containers are then deposited on a discharge conveyer (39). Multiple units (Fig. 1).-Five units as described above may be associated together, the infeed end of each unit having a weighing device (43) so that only eggs of a certain weight enter a particular unit. The discharge conveyers (39) feed the containers to a conveyer (46) leading to a collecting table (47).
