Title: Improvements in superheterodyne receivers for television
IPC: H03D7/08
Filed: 1934-11-05
Abstract: 443,046. Valve circuits for wireless reception. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Nov. 5, 1934, No. 31683. Convention date, Nov. 4, 1933. [Class 40 (v)] An ultra-short wave received in a television receiver is changed by heterodyning to a long intermediate wave, changed again to a very short carrier wave by heterodyning with a short wave, and then rectified. The same local oscillator 4 is used for both frequency changes, an harmonic for the first change and the fundamental for the second. The intermediate frequency is about twice the maximum frequency in the picture signals. A band-pass resonant coupling 12 is used between the second frequency-changing valve 10 and the final rectifier 13 and may comprise a damped oscillatory choke. The rectifier 13 has a push-pull input circuit arranged to remove the ultra-short carrier wave.

For this purpose, one end of the road wheel axle 17 may be drawn up to the frame by means of a turnbuckle 10 whilst the other end may be raised by means of a hand-lever 11 pivoted at its end 13 to the axle and at an adjacent point 12 to a second, swinging, turnbuckle 12a. The transmission of drive is stopped by disengaging one road wheel owing to the action of the ordinary differential gear. Alternatively direct turnbuckle connections may be provided at each end of the axle, in which case one of the friction wheels 8 is connected to the shaft 7 through a clutch. The winch may be driven from the shaft 7 through gearing 14, 15. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements wherein (1) the shaft 7 is mounted in a frame adapted to be rocked about the axis of the winch into engagement with the road wheels and (2) the friction wheels are carried on an intermediate shaft in a rock frame interposed between the shaft 7 and the road wheels.

In one example, an electrode comprising a 2 mm. thick metal plate coated with a 1 mm. thick layer of insulation having a dielectric constant of 7, is moved over an aluminium or copper work piece. In another embodiment, the positive half waves of the voltage supply are damped and a cylindrical electrode provided with insulating rings at each end is rolled over an aluminium workpiece. In a further embodiment, an aluminium foil is conveyed beneath two spaced cylindrical electrodes mounted normal to the direction of travel and each connected to one terminal of a secondary winding of a transformer, the other terminals of the two secondary windings being connected to each other. The treated surface readily adheres to rubber emulsion, printing ink, varnish, plastics, solder and paper. Oxidation may be promoted or removed if one of the half waves of the voltage supply is damped.

Abstract: 1,093,324. Package-banding tools. P. P. PAYNE & SONS Ltd. Aug. 9, 1965 [Aug. 10, 1964], 32554/64. Heading F2G. A tool for banding packages, which is similar to that disclosed in Specification No. 930,212, comprises a U-shaped base 1 providing a jointing station at which overlapped portions 5 and 6 of a tape looped around a package (not shown) are secured by means of a sealing device 9, a gripping device 17 mounted on one arm 2 of the base, a tensioning device 25 mounted on the other base arm 3, a cutter 36 adjacent the sealing device and adapted to sever the upper tape portion 6, and a pressure member 42 secured to cutter and movable into engagement with said tape portion 6 during the cutting operation to bear on the tape along and at the side of the line of cut. Said pressure member is said to prevent longitudinal splitting of the tape when the tape is of plastics material such as polypropylene or nylon. In operation, free tape end 24 is passed below an anvil 39 of the cutter and is clamped between jaw 20 and the base by rotation of handle 23. The tape is looped around a package, passed over the jaw 20, positioned between the cutter and the anvil, and is received in a slotted windlass or boss 26 of the tensioning device. Handle 29, Fig. 1 (not shown), is operated to turn the boss thereby tensioning the tape, a ratchet device (30) preventing reverse boss movement. A metal sealing sleeve (not shown) is placed over the overlapped tape portions, and the sealing device pivoted about a pin (10), Fig. 5 (not shown), into position about the jointing station. Handles 14 are then operated to close jaws (11 and 12), Fig. 5, thereby clamping said sleeve and the overlapped tape portions. During closure of the jaws, a pin 15, on which the handles 14 are pivoted, moves downwards in a guide slot (16), Fig. 5, and a roller 40 depresses the cutter 36 thereby severing the upper tape portion only. The pressure member 42 comprising a rubber block 42 between metal plates 44 screwed to the cutter 36, bears on the tape adjacent the line of cut and prevents longitudinal splitting of the tape. Said pressure member, which may be of other resilient material or of rigid material, such as metal, may be displaceably mounted on the cutter for relative movement thereto, spring means biasing the member towards the tape during the cutting operation. The tensioning device is provided with a deflecting guide plate 32 to deflect the tape in the opposite direction to that in which the windlass is rotated. Reference has been directed by the Comptroller to Specification 930,212.
