Abstract: 1,252,074. Transistor amplifying circuits; frequency discriminators. RCA CORPORATION. 28 Feb., 1969 [29 Feb., 1968], No. 10736/69. Headings H3A and H3T. In an arrangement comprising a plurality 22, 38, 54 of cascade connected transistor stages, each including an emitter-coupled amplifier, e.g. transistors 24, 26 coupled by resistor 32 driving an emitter-follower amplifier, e.g. transistor 28, a first resistor 142 couples a bias supply to one of the transistors, i.e. 26, 42 in each of the first and second stages, and a second resistor 136 couples a feedback voltage from the emitterfollower transistor 64 of the last stage to the other of the emitter-coupled transistors, i.e. 26 in the first stage: the resistance values of the two resistors 136, 142 is such that-the D.C. voltage drops developed across them are equal. The embodiment comprises an f.m. receiver in which the mixer feeds i.f. via tuned circuit 20 to an integrated circuit i.f. amplifier comprising the stages 22, 38, 54, which feeds into a limiter 70 comprising the transistors 72, 74 emittercoupled by means of transistor 76. The transistors 74, 24, 42, 58 are biased from an arrangement 134, comprising transistors 124, 126, resistors 128, 130 and 132, and diodes 125, 127. The voltage drop across the feedback resistor 136, which is used for stabilizing the standing condition of the amplifier, being decoupled for A.C. by capacitor 144, is made equal to that across bias circuit resistor 142 so that the base potentials of transistors 72, 74 may be kept equal to provide symmetrical limiting. The H.T. supply to the amplifier is stabilized by means of resistor 118 and Zener diode 116, being fed to stage 22 via emitter-follower 120 and stages 38, 54 via emitter-follower 122 which also supplies the bias stabilizing circuit 134. The limiter 70 feeds into a discriminator comprising tuned circuits 84 and an arrangement 90, comprising diodes 160, 162 in conjunction with transistors 170, 172 which bias the diodes into conduction: an output is taken over volume control 94 and audio amplifier 100.

Abstract: 1301397 Single trigger mechanisms for sporting guns VERNEY-CARRON SA 28 July 1970 [5 Aug 1969 2 July 1970] 36494/70 Heading F3C A double barrelled gun has a single trigger mechanism comprising a single trigger 4 mounted for pivoting about a pin which extends transversely of a trunnion 1, the trunnion 1 being mounted for pivoting about its longitudinal axis. The trigger 4 carries an arm 4<SP>1</SP> which is arranged to co-operate, according to its angular position, with either of two sears 6, 8. Means is provided which is arranged to be engaged by the rear end of one 5 of the cocked strikers so as to pivot the trunnion 1 and thereby position the trigger arm 4<SP>1</SP> for co-operation with the sear 6 through which the first shot is to be fired. After the first shot the means is released due to the firing movement of the striker 5 and a spring 15 is provided for pivoting of the trunnion 1 to position the trigger arm 4<SP>1</SP> for co-operation with the other sear 8. In the construction shown the means consists of an eccentric projection 1<SP>1</SP> rigid with the trunnion 1. The spring 15 acts on the trigger-trunnion assembly through a rod 11 and a support 9 connected to the trigger. A further support 10 opposed to the support 9 is also provided and co-operates with a further rod 12. The rods 11, 12 actuate the ejectors housed in the barrel assembly 14 when the gun is opened. Movement of the arm 4<SP>1</SP> is limited by bosses 6<SP>1</SP>, 8<SP>1</SP> on the sears 6, 8. The spring 15 may be replaced by a leaf spring (Fig. 6, not shown). In a modification the means arranged to be engaged by the striker comprises a block, the block having a link pivoted thereto. The link engages a pin extending laterally of the trunnion (Figs. 7, 8, not shown). In a further modification an arrangement is provided whereby the barrel to be fired first may be selected. The arrangement comprises a supporting lever 37 and a selecting lever 40 pivoted on the trunnion and engaging the lever 37, the supporting lever 37 forming the means arranged to be engaged by the striker. The selecting lever 40 may be held in a forward position by a manually actuatable selecting device which includes a projection 42 whereby on engagement of the lever 37 with the cocked striker the levers 37 and 40 are pivoted so that the trunnion is pivoted. When the lever 40 is retracted no such pivoting of the trunnion takes place and a spring and rod assembly (Fig. 12, not shown) pivots the trunnion in a direction contrary to that when the lever 40 is held in its forward position. A spring loaded lever (47, Fig. 12, not shown) is provided and is arranged to engage the other striker so that on the firing of the gun for the first time the other striker moves forwardly releasing the spring loaded lever. This lever under its spring loading engages a pin extending transversely of the trunnion to pivot the trunnion.

The rate of count may vary as the count proceeds, the rates being in dependence upon web and reel speed, as sensed by the speed detectors, the geometry of the reel stand, the position of the reel speed detector and the position of the brushes and knives.
