Abstract: 863,070. Discharging ampoules. AUTOPACK Ltd. Jan. 21, 1959 [Jan. 24, 1958], No. 2392/58. Class 78 (1). Ampoules are discharged one-by-one from hopper 50 on to the slots 43 of fixed plate 42 whence they are conveyed by walking beam conveyer 19, 20, and the movement of the conveyer is employed to produce several different movements in the hopper to facilitate the said discharge. The movement from beam 20 is transmitted to hopper 50 via rod 25 and arm 26. Arm 26 is pivoted at 27 to base-plate 1 of the hopper and resiliently locked thereto by pawl 28, also pivoted to base-plate 1. The hopper, therefore, pivots about 24, its stud 24 moving in the slot 23 of fixed support 2. This pivotal movement of the hopper causes an ampoule to be deposited in each slot 43 as the hopper swings. Agitation of ampoules.-The rocking movement of hopper 50 causes three other move. ments. Firstly, it pivots member 11 about pivot 14 to shake up the ampoules, member 11 being connected by pin-and-slot to fixed support 2. Secondly, it causes flange 5 of the hopper to engage fixed roller 17, the vibrations of the flange shaking the ampoules. Thirdly, serrated edge 37 of the hopper engages fixed roller 38 to cause additional vibration of the hopper. Hopper construction.-Hopper 50 has inclined base-plate 1 provided with upstanding flanges 5, 6 to present an open side, the discharge shoot 8 being adjustable at 41 for ampoules of differing sizes.

Title: Improvements in and relating to welding apparatus
IPC: B23K11/31
Filed: 1943-02-19
Abstract: 561,821. Welding. BRIGGS MANUFACTURING CO. Feb. 19, 1943, No. 2784. Convention date, March 30, 1942. [Class 83 (iv)] In an electric spot welder, the movable electrode is carried by a piston reciprocated into and out of engagement with the work in a cylinder carried by a head, the piston being normally maintained in its retracted position and the head carrying a second piston in a cylinder concentric with the first cylinder, the second piston being selectively operable in the retracted position of the first piston, to move it in a direction to cause the head together with the electrode to increase the clearance between the electrode and the work. The electrode may thus be raised when desired sufficiently to clear ribs or raised portions on the work when passed beneath the electrode. The electrode operating piston 20 is reciprocated in a cylinder 15 on the head of which is carried mechanism as described in Specification 547,110 for controlling the operative cycle of the machine including the welding circuit. The piston is held in raised position by fluid pressure permanently supplied to the chamber 23. The electrode 10 is bolted to a plate 34 secured by bolts 35 to a sleeve 33 and to a plunger 25, the head 24 of which is slidable on the inner surface of the skirt 22 of the piston and is pressed by a spring 28 against a shoulder .26 thereon. The cylinder 15 is bolted at 19 to a.sleeve 17 which forms a guide for the sleeve 33 of the plunger .and also carries a piston 40 so that it .may be raised or lowered by fluid pressure in a cylinder 41 secured to a bearing 45 attached to an arm 42 fixed to the framing of the machine. The cylinder has a lower end 48 bolted thereto and has a liner 43 separated by electric insulation therefrom. Rotation of the cylinder 15 during adjustment is prevented by a follower 56 thereon engaging guide plates 55 secured to the arm 42. Rotation of the electrode is prevented by guide plates 61 on the electrode supporting structure 59 engaging a member 62 secured to the cylinder 41. When fluid is admitted to the upper end of the cylinder 15, the piston 20 and plunger first move together to bring the electrode into contact with the work, whereupon the piston moves relatively to the plunger to compress the spring 28 until the lower end of the skirt engages :the upper .end of the sleeve 33 when full line pressure is applied to the electrode to complete the weld. The upper end of the cylinder 15 is then exhausted so that the electrode is raised by the pressure in the chamber 23. The cylinder 15 with the piston 20 in its raised position may then be raised as a unit by pressure applied to the lower end of the piston 40 so that the lower end of the electrode may clear ribs on the work and the parts are then returned to operative position.

[Also in Division F2] A clamping device for a circular saw blade 6, Fig. 1 (not shown) comprises an overload slipping clutch having a first spring-loaded clutch flange 11 which presses the blade against a second clutch flange 18, the first flange, springs 9 and a housing 8 being assembled in a singlepart constructional unit 5 which can be clamped fast by a retaining screw 4 screwed into the end face of a drive shaft 1. The housing of the unit 5 consists of a cup-shaped part 8 and a flanged part 10 which engages a shoulder 14 on the clutch flange 11 to retain the part 8, discsprings 9 and clutch flange as the unit 5. The screw 4 passes through bores in the housing part 8 and clutch flange 11 into a threaded bore 2 in the end of the drive shaft which is formed with recesses 34 engaged by dogs 33 on the flange 11 so that rotation of the shaft is imparted to the unit 5. The second clutch flange 18 is rotatably mounted on the drive shaft 1 and carries bolts 19 which engage recesses in the saw blade so that the flange and blade rotate together, the shaft being mounted for rotation in a bearing 21 in a carrier part 22. The face of the first clutch flange is formed with channels 17 to reduce the area in frictional contact with the blade. When the screw 4 is removed the unit 5 can be removed for replacement of the saw blade. On reassembly, the saw blade is placed on a shoulder 20 of the second flange 18 with the bolts 19 engaging the holes in the blade, and the unit is mounted on the end of the shaft. If the load on the saw is excessive, the channelled surface of the first flange permits the blade and second flange to slip relative to the drive shaft and first flange.

Title: Improvements in television receivers
IPC: H04N5/53
Filed: 1961-01-25
Abstract: 909,791. Automatic gain control. LOEWE OPTA A.G. Jan. 25, 1961 [Jan. 26, 1960], No. 2897/61. Class 40 (5). The invention relates to a television automatic gain control circuit of the " gated " type, in which positive-going pulses from the line output transformer are applied over condenser 12 to the anode circuit of an automatic gain control valve 8, the cathode of which is coupled by common resistor 9 to the cathode of video stage 5 and an automatic gain control voltage is taken from the anode of the valve 8. Such an arrangement is liable to overload during the initial starting period, since the line output is the last part of the receiver to become operative, and once overloaded cannot function since the modulation from which the automatic gain control is derived is removed in the overloaded stages. To prevent this, the grid of the control valve 8 is connected by lead 13 to the cathode of the last intermediate frequency stage 1. The cathode circuit of this valve includes decoupled resistor 15, and if the valve overloads its cathode current rises, applying a positive bias to the grid of control valve 8 which makes this valve conductive to generate an automatic gain control voltage as soon as the line output is present at its anode.
