Abstract: 982,224. Converting. STANDARD TELEPHONES & CABLES Ltd. June 7, 1963 [June 12, 1962], No. 22754/63. Heading H2F. The Specification relates to an electric supply arrangement for a data processing system which receives information in the form of amplitude modulated pulses and eliminates the pulse frequency and its harmonics with a low-pass filter, thus obtaining the envelope of the pulse train. According to the invention the supply arrangement includes an inverter driven by an oscillator having a natural frequency equal to the pulse repetition frequency or an integral multiple thereof. The supply arrangement (reference 110 in Fig. 1) includes an inverter 120, driven through the amplifier 112 by the oscillator 111, which converts direct current from a battery 130 to alternating current at 14. If required the inverter output may be rectified at 113 to provide a direct current supply also. The oscillator is synchronized by a signal supplied at 16 from the data processing system. The inverter 120 comprises two switching transistors and a transformer with centre-tapped primary connected in biphase arrangement (Fig. 2, not shown). The data processing system may be a pulse radar apparatus in which echoes from fixed objects are eliminated by accepting only the Doppler frequency component.

Title: Improved method of joining the ends of metal strappings for cases, bales and the like
IPC: B65B13/30
Filed: 1936-08-28
Abstract: 471,634. Fastening bale-ties. HALL, T. E., and PACKERS SUPPLY CO., Ltd. Aug. 28, 1936, No. 23655. [Class 146 (ii)] A method of joining the overlapping ends of meta.l strapping comprises ridging the ends longitudinally, and forming in the upper end 1, Fig. 2, tongues 4 having their free ends wider than their roots and extending through correspondingly shaped closed slots 5 in the lower end 2, so that they lie within the space below the ridged overlapping ends and have their wide free ends beneath the narrow ends of the slots. The tongues are preferably alternately arranged and bent along the median line of the tie. To form the joint one end of the tie is gripped by a cam 11, Fig. 5, and, after it has been passed round the bale, the other end is gripped and tensioned by a device 35 such as that described in Specification 416,977, [Group I]. The overlapping ends lie between a die 6, Fig. 6, formed with alternate recesses 7 and a block 13 sliding between guides 8. The block 13 carries punches 17 in grooves 16. Each punch 17 is formed with a cutting edge 18, Figs. 11 and 12, laid back at 19 and with ground back flanks 20. A block 29 is slidably mounted on the block 13, and is normally pressed away from it by springs 32, to an amount limited by a pin 26. The block 29 is formed with faces 37 co-operating with the upper ends of the punches 17, and has screwed to it plates 33 engaging notches 22 in the punches. The blocks 13 and 29 are separately depressed by cam faces 45, and 44, 46 formed on a hand lever 51 and co-operating respectively with rollers 39 on the block 29 and a roller 27 carried by a post 24 secured to the block 13 and passing freely through the block 29. When the lever 51 is operated the block 13 is first depressed, co-operating with the die 7 to hump the bale-tie, and the block 29 then descends and operates the punches 17 to form the joint. The punches enter the bale tie at an acute angle a, Fig. 12, and the surfaces 19 bend over the tongues. When the handle is raised the block 29 is released by the cams 44, 46 and raised by further cams on the hand lever co-operating with slotted sliding plates, 47, which fit over pins 40 on the block 29. The punches 17 are thus withdrawn by the plates 33. The block 13 is then raised by a lever 52, Fig. 5, which is operated by the handle 51 and which engages under the roller 27. The free end of the tie is severed by cutters 55 carried by the base plate and block 13. Specification 428,388, [Group XVII], also is referred to.
