Abstract: 191,777. Taggart, J. Scott-, and Radio Communication Co., Ltd. Sept. 12, 1921. Thermionic detectors; atmospherics and undesired signals, eliminating or limiting. - Relates to current limiting devices, particularly for lessening interference in wireless reception. The high - frequency currents are preferably rectified and applied as uni-directional currents to a twoelectrode valve, to the grid of a threeelectrode valve, or to the negatron " described in Specification 166,260. As shown in Fig. 1, the received waves are amplified by valve Vo and rectified by a two-electrode valve, V1 the circuit of which includes a condenser C, and resistance R connected across the grid and filament of the " negatron " V2. By this arrangement, all rectified impulses are reduced to the same wave form before being applied to the limiter. The " negatron " is adjusted to work at the point X, Fig. 2, so that a strong positive impulse carries the applied voltage over the peak of the curve and may produce less effect than a weak impulse. The " negatron " may be replaced by a three-electrode or a two-electrode valve working at the lower or upper bend of its curve, a small positive potential being preferably applied to the anode of the two-electrode valve. In a further arrangement, using two valves V1, V2, Fig. 6, connected reversely to the input terminals X, Y, the valve V1 is adjusted to operate near the bottom of its curve, while the grid of the valve V2 is made so negative that no current passes until the incoming positive potentials exceed the potential of battery B2. Normal signals influence the valve V1 only, but strong signals or atmospherics cause the current in valve V1 to become zero and an increasing current to flow through valve V2. Specifications 158,762 and 185,133 also are referred to.

Title: Improvements in or relating to loading apparatus for ordnance
IPC: F41A9/14
Filed: 1950-10-03
Abstract: 703,319. Gun-loading mechanism. MOLINS, D. W., HAYSOM, J. C., MASON, J. A., and MOLINS MACHINE CO., Ltd. Jan. 1, 1952 [Oct. 3, 1950; Oct. 18, 1950; July 10, 1951], Nos. 24195/50, 25417/50 and 16377/51. Class 92(1)  Apparatus tor loading ordnance comprises a projectile tray 2 and a charge 1 arranged side by side in the firing position, Fig. 2, aside and clear of the breech, and movable in convergent paths so that the tray 2 and later the tray 1 are moved into the ramming position. In the form shown the tray 1 is carried by an arm 3, Figs. 1 and 2, rotatable on bearings surrounding the recuperator casing 5 and is swung to and fro by a motor 6, Fig. 12, via worm 7, wormwheel 8, and linkwork 1, 10, 11. The tray 2 is pivoted at 15 to the tray 1 and is linked at 20 to an arm 22 which is pivoted at 23 to a bracket 24 secured to a non-recoiling part of the gun. By this means the tray 2 swings relatively to the tray 1 during rotation of the arm 3 to occupy the ramming position shown in Fig. 1. After the projectile has been rammed the arm 3 continues its clockwise rotation to bring the charge tray 1 into the ramming position. The arm 22 also carries cams 56, 57 which coact with a follower linked at 50, 51, 52 to a pivoted member 48 whose function is to prevent the projectile being thrown out of the tray during the swinging movement of the arm 33; in a modification the tray has two curved surfaces separated by a rib for-serving this purpose. The trays 1 and 2 are fitted with rammers 30, 25 respectively, the former being connected to a chain 31 and the latter to a cable 26 which are driven by an electric motor 32. The drive is such that the rammers move in opposite directions. The rammer 30 is pivotally mounted so that it may yield when passing rearwardly under the charge whilst the rammer 25 is ramming the projectile into the breech chamber. The projectile is guided during the ramming operation and prevented from moving backwards after having been rammed, by members 125, 128, on a tray 122 connected to a slide 123 which is reciprocated in suitably timed relation by a forked arm 140 as shown in Fig. 12, the slide being mounted on a rail 124 adjacent the breech ring. Fig. 11 (not shown) gives the circuit diagram for actuating and controlling the entire mechanism whereby once the trays have been loaded and a switch closed, the projectile tray is first brought into the ramming position, the projectile then rammed into position being guided by the guides on the tray 122 and being prevented from backward movement until the charge tray is swung into position, and the arm 3 with the trays returned to the initial position after the ramming of the charge. Specifications 578,622 and 703,320 are referred to. The first Provisional Specification refers to Specification 578,621.

Title: Improvements relating to the printing of thick fabrics and to stencil printing apparatus
Inventor: LECKIE THOMAS LIDDLE
IPC: B41F15/08
Filed: 1959-07-14
Abstract: 895,706. Screen printing machines. BRADFORD DYERS' ASSOCIATION Ltd. July 13, 1960 [July 14, 1959; Feb. 3, 1960].'Nos. 24221/59 and 3877/60. Class 100(2) In a multi-colour screen printing machine in which a carpet is moved intermittently along a horizontal endless chain conveyer 10 and is subjected to a printing process at a plurality of printing stations during the rest portions of the movement, each station comprises a narrow bottomless colour box CB and a screen S above the carpet and a perforated support 5 and a suction box SB beneath the carpet. The colour box, which traverses the screen during the printing process and contains colouring matter of a relatively free flowing nature, is, in conjunction with the suction box, associated with means whereby the pressure difference across the screen and fabric is maintained substantially constant during printing. The support 5 has imperforate edges 61, 62, herring-bone fashioned channels 63 into which the perforations 60 open, and slots for accommodating spiked rollers such as 50, 51, 52 which ensure positive movement of the carpet. The screen consists of gauze 75 stretched across the underside of a metal frame 76. The gauze meshes are closed along the side edges of the screen and also over an area at each end large enough to receive the complete colour box. The latter has a flexible lower edge formed by rubber strips 70 which make a seal with the imperforated parts of the screen surface. The colouring matter for each box CB is supplied from a container 80 by a pump 81 through a pipe 82 containing a manually adjustable valve 83 to distributers 84. An electric probe 85 responsive to liquid level is provided in each box and is electrically connected to control the pump 81. When the probe responds to a reduction in the level in the box the pump must first fill the pipe 82 and there is a delay before the colouring matter actually enters the box. During this time the liquid head is decreasing, and in practice it is found that it normally decreases during each printing stroke at substantially the same rate as the suction on the unprinted carpet increases. If it is necessary to supply matter to the box during a printing stroke and yet let the liquid head fall to offset the rise in suction, the pump may be operated to deliver the matter at a rate less than that at which it leaves the box such adjustment being effected by either controlling the pump speed or the valve 83. To allow movement of the carpet each colour box and screen is lifted at the end of each printing stroke by mechanism comprising levers 92 which bear through rollers 91 on rails 74 to lift the box, and rods 95 which bear on rails 77 by which the screen is carried.
