Abstract: 1,117,403. Road traffic signals. E. W. BLISS CO. 16 Nov., 1965 [12 May, 1965], No. 48573/65. Heading G4Q. [Also in Division H3] A control system for road traffic signals comprises four bi-stable circuits MM1-MM4, Fig. 1, corresponding respectively to main road green and caution and side road green and caution, each adapted when energized to illuminate the corresponding signal, to de-energize the preceding bi-stable circuit, and to trigger an associated monostable circuit TM which, on timing out, energizes the succeeding bi-stable circuit. Each monostable circuit TM may comprise a unijunction transistor relaxation oscillator having an adjustable time constant. Relay circuit.-The signal lamp circuit includes a relay 52, Fig. 2, arranged in series with a silicon controlled rectifier 20, the relay contacts 54 controlling the energization of the signal lamp 22 from an A.C. supply 28, and is characterized in that the relay is energized by a full-wave rectified pulsating voltage derived from the A.C. supply. Consequently the relay contacts can close on either half-cycle of the A.C. supply, and wear due to migration or pitting is reduced compared with the system which uses A.C. across the relay and rectifier 20 and which can only operate on the same halfcycle of the supply.

Title: Automatic firearm having a servo-trigger mechanism
IPC: F41A19/33
Filed: 1973-10-26
Abstract: 1437240 Recoil controlled sear mechanisms FRANCE ARMED FORCES MINISTER OF 26 Oct 1973 [27 Oct 1972] 50052/73 Heading F3C In an open breech type automatic firearm, a pivoted sear 2, mounted in a removable casing borne by a breech casing, is operated against a spring 5 by a cam 7 borne by a longitudinally movable slider 8 against the action of a spring 10, to retain the breech in its rearward position, the cam being locked in its forward, sear actuating position, and the slider being operated by a percussion control device drawing energy from a retracting part 1 of the breech or associated mechanism, this device being selectively neutralized for burst firing, and the cam locking being selectively neutralized for retraction of the slider. A selection cam 28 is rotatable by a lever 29 to provide burst firing, single shot firing or a safety lock. In the first mode, it allows movement of the percussion control device neutralizing means in the form of a catch 17, and movement of a plate 21 fixed to a rotatable firing control shaft 6. Upon recoil of the breech mechanism part 1, a latch 13 of the control device is pivoted, but a counterlatch 11, which is spring biased with the latch 13, is held by the catch 17, thus providing no actuation of the slider 8, the sear 2 remaining retracted, as in Fig. 1. To cease firing, the shaft 6 is rotated anti-clockwise, causing a finger 20 to withdraw the catch 17, to allow movement of the latch 11, with the succeeding movement of the counter-latch 13 due to recoil, to actuate the slider 8 and thus the sear 2, to block the breech block. Here, the slider 8 is retained by a hook 22 actuated by mating surfaces R1, R2 thereof. To initiate firing, a lever 25, actuated by a catch 27 coupled to the shaft 6, engages a roller 26 coupled to the hook 22 to retract it, and thus the sear 2. For single shot firing, the selection cam 28 retains the catch 17 away from the latch 11, so that upon a single recoil, action of this latch following movement of the catch 13 and subsequent engagement with a stop 1b of the block part 1, causing rotation of the latch, causes actuation of the sear 2. For the safety mode, the plate 21 fixed to the shaft 6 is held in its Fig. 4 position to hold the catch 27 away from the lever 25, to avoid actuation thereof and thus retraction of the sear 2.

Abstract: 1,017,770. Stripping apparatus. K. W. JONES. Dec. 14, 1964 [Dec. 30, 1963], No. 50791/64. Heading B4B. A device, for stripping scrap from a cut and scored paperboard blank, comprises a frame 1, 2, Fig. 1, in which are journalled vertically-spaced, horizontal shafts 5, 7, driven in timed relation, as by gears 10, 11; a timing wheel 14, Fig. 2, is keyed to the overlying shaft 7 and a disc or wheel 26 is keyed to the underlying shaft 5 for rotation therewith, to define a passage for the blank 22, which is contacted by means such as lugs 19, 19a projecting from the periphery of the timing wheel 14 so that an area of the blank 22 is deflected downwards into contact with the disc 26 and broken free from the remainder of the blank. As described, the timing wheel 14 has a rim 15 with spaced, threaded openings 16 to which brackets 17 carrying the lugs 19, 19a are screwed. The spacing of lugs around the wheel may be varied by selection of the threaded openings for the brackets. In operation, paperboard 22 travels beneath the wheel 14 and is supported on spaced guide rods 23. The lugs 19, 19a make rocking contact with the paperboard and contact the areas to be removed, these areas being pressed downwards as at 24, so as to be impaled on teeth 25 provided on the disc 26. Subsequent rotation of the disc causes the scrap to be removed by contact with the under surface of side plates 28 so that it falls on to a conveyer 30 for transport to a scrap box. In a further embodiment a smooth surfaced wheel 31 cooperates with a similar smaller wheel 32 having a resilient peripheral band 33, to advance the blank and support it adjacent the edge of an area to be scrapped. Co-operating with wheels 31<SP>1</SP>, 32 is a wheel 15a having spaced lugs 35, 35a which break the section 36 downwardly over a rotating smooth disc 37. In another embodiment, threaded openings 40a in a wheel 40 receive resilient tips 41 to strip and deflect part of a blank downwards over a band 42 mounted on a wheel 43.
