IPC: B21D26/02
Filed: 1964-03-03
Abstract: 1,110,401. Forming sheet material. WHESSOE Ltd. 1 June, 1965 [3 March, 1964], No. 8894/64. Heading B6J. [Also in Divisions B3 and B5] A method of forming a blank 5 of metal or other material comprises applying fluid pressure between the blank and a backing plate 2 which clamps the blank to a die 1, the force restraining inward movement of the edge of the blank being greater in regions of the blank experiencing most inward movement. The free edge 5A of the blank wrinkles during inward movement, the depth of the wrinkles and the restraining force they apply when being ironed out between the die and plate 2 being greater in the regions where most inward movement occurs. The depth of the wrinkles are controlled by recessing the plate at 7, or the die or both, Fig. 2-4 (not shown). The shape of the step 8 may vary at different points around the die. Towards the end of a forming operation, the clamping force applied by plate 2 is reduced, without loss of fluid from the die, to assist in forming sharp bends near the edge of the die.

Title: Shear assembly for a moving web
IPC: D06H7/02
Filed: 1964-03-03
Abstract: 1,008,308. Shearing. CONTINENTAL CAN CO. Inc. March 3, 1964 [March 18, 1963], No. 8908/64. Heading B3W. A shear assembly for a moving web including a shear fixedly mounted along a path of movement, feed means for drawing the web through said sheer and web slack providing means disposed intermediate said shear and said web feed means and adapted automatically to supply from the length of slack to said web feed means whilst that portion of the web to be cut by the shear remains stationary during the operation of the shear. The assembly comprises a fixed shear blade 17, Fig. 1, a movable shear blade 18, a driven feed roll 22 and a pressure roll 23, and a loop-forming device comprising a pair of guide rolls 25 and 26 and a third guide roll 27 which can be moved vertically between the rolls 25 and 26. There are secondary feed rolls 30 and 31 and pivoted drags 32 which prevent retrograde movement of the web 20. The movable blade 18 is reciprocated by eccentrics 86 on a shaft 84, the eccentrics being connected to the blade by rods 88 of adjustable length and the shaft being driven through a onerevolution clutch. The fixed blade is carried by a frame 74 and has means by which it is adjustably mounted in brackets 75. The vertical movement of the third guide roller 27 is derived from a fluid motor 103 pivotally attached to the frame of the shear. The secondary feed rolls 31 are rotatably mounted on a shaft which is supported in eccentric bushes. The bushes can be rotated by a gear 61 which is rotated by a gear 62, a crank arm 65 and a fluid motor 68 to bring the rollers 30 and 31 into and out of co-operative engagement with the web 20. Operatic .-The one-revolution clutch and the fluid motor 103 are operated by common control means, so that as the blade 18 begins to move upwards the guide roll 27 moves downwards from the position shown in Fig. 1 at such a rate that the portion of the web 20 between the shear blades remains stationary at the time it is severed. The guide roll 27 continues to move down to a position below the path of the web, the trailing end of which is drawn through the feed rolls 22 and 23. The fluid motor 68 is then actuated to raise the secondary roll 31 and feed the newly-formed leading end of the web through the shear to the feed rolls 22 and 23.

Abstract: 719,247. Automatic feed weighers. DRIVER & SON, Ltd., G. April 9, 1953 [April 9, 1952], No. 9076/52. Class 143 In automatic batch weighing or packing of ferromagnetic material such as small metal articles or granular material an electromagnet 13 between the feeding means 11 and the weigh vessel 12 or package is energized after a predetermined weight or quality has been delivered so as to avoid errors due to material in flight at the instant when the main feed is cut off. The weigh vessel 12, suspended on a weighbeam 14. operates through trip mechanism, after its descent under full weights, electric relays simultaneously cutting off the main feed and energizing the electromagnet. The discharge gate 15 then opens. A plastic plate 21 covering the electromagnet permits subsequent release of the material caught in flight. The feed means 11 may be a vibratory or endless belt conveyer. The electromagnet is adjustably positioned between the conveyer 11 and weigh vessel 12 and adjustable in height by a slotted link 17 pivoted to a support 16. The weigh vessel may be made automatically to move-away from the path of flow when a delivery has been made, at the same time energizing the electromagnet. The conveyer 11 may be continuously operated, and diverted from the weigh vessel when full weight is reached.

Title: Radio interference suppressors
IPC: H04B15/02
Filed: 1972-02-29
Abstract: 1383446 Inductors SIEMENS AG 29 Feb 1972 [23 April 1971] 9189/72 Heading HIT A choke for interference suppression has a winding 8 formed on a core 1 comprising at least two annular parts 2 and 3, stacked coaxially. A first part 2 is of magnetizable iron laminations or wound strip made from, e.g. a silicon containing ferrous alloy and the remaining part is of a ferrite material, the ferrite parts having at least one air gap or slot. The iron laminations may alternatively be of an unalloyed deep drawn iron material. Two radial air gaps can be produced by forming the ferrite annulus in two halves and placing the halves almost together, but preferably a single radial air gap is provided. Instead of gaps extending completely through the ferrite, incursions or slots may be formed on the inside of the surface of the annulus so that the effect of air gaps is achieved and noise due to magnetostriction is kept to a minimum. In one embodiment of the invention, the effective cross-sectional area of the ferrite core section is made equal to or greater than that of the laminated core section, which is made up of 17 ring laminations. In a further embodiment, the cross-sectional area of the ferrite core section, which has a height of 3 mm., is a third of the total cross-sectional area of the core. The casing 4 is filled with a potting resin, 6, to which 40% of ground quartz has been added, and which remains elastic after setting. The resin penetrates between the core sections and laminations to secure sound damping. The casing is surrounded by a double layer of insulated copper wire, the winding direction, but not the winding sense of which is reversed after the 1st layer has been completed. An air gap or slot 0À2 to 0À3 mm. wide is ground in the core section 3. In one particular arrangement of the invention having a winding of current rating 2À5 A, the core has an inner diameter of 20 mm. and an outer diameter of 30 mm.

Title: Improvements relating to the modulation of magnetron oscillators
IPC: H03C5/04
Filed: 1940-05-24
Abstract: 541,120. Magnetrons and circuits therefor. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 24, 1940, No. 9217. Convention date, May 24, 1939. [Classes 39 (i) and 40 (v)] Magnetron oscillators are modulated in amplitude or in frequency by applying the signal voltage to two similar electrodes in such manner that the undesired kind of modulation is compensated out. As shown in Fig. 3 the anode is divided transversely to the axis forming in effect two separate split-anode magnetrons 9, 11. Lecher-pairs 21, 23 secured to each lie closely adjacent to each other and are coupled to the aerial circuit 27. The signal source 29, Fig. 5, is connected through an amplifier 35, two potentiometers 31, 33 and two separate amplifiers 37, 45 and transformers 41, 49 to the anode supply circuits of the respective magnetron sections 9, 11. Potentiometers 53, 55 across the anode source 51 are so adjusted that the magnetrons act on opposite slopes of the curve indicating output amplitude as a function of anode voltage, and the reversing-switch 43 is placed so that the signals reach the anodes in opposite phase. Under these conditions, amplitude modulation is effected without frequency modulation. With the switch 43 in its other position, frequency modulation without change of amplitude is effected. In a modification (Fig. 6 not shown), the same results are achieved by applying the signal voltage to end-plates of the magnetron, a reversing switch being provided in one of the circuits. In a further modification, the signal voltage is applied to the divided anodes, which are biased equally, and the end-plates are differently biased.
