Title: Improved method of and means for bending sheet metal
IPC: B21D5/06
Filed: 1944-12-14
Abstract: 586,402. Angular bending. HOWEY, W. L. Dec. 14, 1944, No. 25099. [Class 83 (iv)] Dies and formers.-In bending sheet metal progressively by feeding it between a pair of press dies, one of which is stationary and the other is given a vibration of small amplitude and high frequency perpendicular to the direction in which the sheet is fed between the dies, the dies each consist of relatively fixed portions provided with tapered internal or external surfaces applying both vertical and lateral pressure to the work and shaped to produce semi-open and completely closed sections. Sheets are thus provided with marginal strips of semicircular, circular, oval or other section, or converted into split tubes or bent to form rectangular channels or other sections for making metal doors, cabinets and other furniture. In making a circular beaded edge, the upper movable die, which is carried by a bolster suspended on connecting rods driven by eccentrics on a power-driven rotary shaft, so as to give a stroke of <1>/16 inch at a frequency of 1500 reciprocations per minute, is provided on the forward portion of one edge with a surface which is tapered and has a semicircular rib a, Figs. 2 and 7, running lengthwise thereof to co-operate with a semicircular groove d, Fig. 3, of uniform depth'running the full length. of the lower die so as progressively to produce an initial bend of semicircular section with an upstanding extension as shown in Fig. 10. One wall of the groove is wedge shaped at d<1> to co-operate with the rib. The final portion of the die consists of a downwardly-tapered tunnel c, Figs. 2 and 6, of inverted U-shape which co-operates with the groove in the lower die to convert the edge to circular form. Between the two portions of the upper die is a recess b co-operating with a mandrel e, Figs. 3 and 12, pivoted on a stud g on the lower die so as to adjust itself to irregularities, the mandrel having an inverted U-shaped part h extending over the groove d to engage the upstanding portion of the strip. The mandrel is provided with a rod k of circular section, tapering to a diameter equal to the internal diameter of the circular section to be formed. The sheet is fed by hand or automatically between the dies. In making flanged channel sections in three successive but continuous stages, the upper die is provided on its entrance end with a central mallet m, Fig. 15, coacting with spaced wedge strips n, Fig. 16, on each side of a central groove p in the lower die to bend the strip into the section shown in Fig. 18. In the intermediate stage, the upper die has a central mandrel r, Fig. 19, and two converging die faces s co-operating with the groove p to close together the upstanding flanges and bend them progressively into the form shown in Fig. 21. Finally, diverging die faces t, Fig. 24, continue the handrel of the upper die to coact with the groove p and a central gap u between a pair of flat plates v in the lower die to bend over the flanges as indicated in Fig. 25.

Abstract: 1,081,591. Rope railway control. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 15, 1966 [June 18, 1965], No. 25787/65. Heading B7N. Signalling system for the automatic control of a rope railway comprises four conductors extending along a route, the first SSL (Secondary Stop), by virtue of diode D7 carries positive half-cycles of the supply from source 1, 2 and includes a series of pull-wire switches PWS for stopping a train in an emergency, the second SL (signalling) carries negative half-cycles and includes a series of push-button switches which are actuated one or more times for normal control (1-stop, 2-start forward, 3-start reverse and 4 (or more) stop) the third RL which forms the supply return circuit and the fourth BL forming a bell circuit with a series of bells SD1 &c. along the route and at the haulage station, detector circuits which control the haulage motor drive circuits via a counter and lamp circuits indicating the train movement and any fault conditions on the line. Assume the train is halted and the train attendant wishes to move it forward, under this initial condition relays ES, LA, ESS, TA and S are operated and on first actuation of the pushbutton SB relay LA releases picking up relay L whereby contact L1 operates slow to release relay N which in turn at contact N1 initiates operation of slow to operate relay P, contact L2 opens the hold circuit for counting relays A, B, C and D and contact L5 operates relay A via its left hand winding over the circuit shown. On first release of the push-button relay LA picks up releasing relay L but relay A is now held via a circuit through its right hand winding, the left hand winding of relay B, which picks up, and contacts P3 and ESS1. On second actuation of the button relay LA releases, picking up relay L whereby relay A is released but relay B is retained energized and on the second release of the button relays LA and L revert to their initial states and relay B is held via a circuit which includes a winding of relay C, which picks up. When relay P now releases, relay G picks up releasing relay S whereby relay J is energized. Contacts J1 and B3 light lamp LP8 to indicate forward direction of haulage and contact J5 extinguishes haulage stop lamp LP10. Contacts J3 and J4 are closed in the forward FC and reverse RC contact circuits but since relay D is not picked up only the forward contactor circuit FC is completed via relay contact B4. The Specification also described circuit operation for " start reverse," " stop " and " emergency stop " and also indicates how various faults on the lines are indicated by the lamp circuits.

Abstract: 1,048,926. Television; automatic gain control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 28, 1963 [July 3, 1962], No. 25822/63. Headings H3Q and H4F. In a medical X-ray television system having a video amplifier provided with automatic gain control, the gain control signal is applied to the amplifier only during times when the amplifier is transmitting information relating to a selected area or areas of the transmitted image field, said area(s) being less than the complete image field. A selected area may be made adjustable in both position and size. A suitable circuit for carrying out the invention is illustrated in the Figure where a main video amplifier 1 has automatic gain control provided by a circuit 5 in which a signal derived from stage 4 of the main amplifier is amplified in stages 6-9 and then rectified in stage 10 to obtain a control signal which is applied over lead 11 to the first stage 12 of the amplifier. In order that the control signal may be due to only a selected part of the televised picture area, a control stage 16 is provided which renders stage 8 of circuit 5 operative during predetermined parts only of each line and frame. Circuits 17 and 20 are triggered by line and frame synchronizing signals respectively and produce delayed pulses which trigger circuits 24 and 25. Pulses from these latter circuits are combined and applied to control stage 8. Adjustment of resistors 22 and 23 (preferably by a common control mechanism) permits adjustment of the position of the selected picture area, whilst adjustment of resistors 26 and 27 controls the duration of the control pulses and hence the selected area. A three-position switch S I  permits the automatic gain control to be disabled (position a), the automatic gain control to operate as described above (position b) and the automatic control to operate with the reproduced picture blanked via stage 28 outside the area(s) where the control operates.
