Title: Improvements in or relating to a method and apparatus for welding thermoplastic material by heat-contact welding
IPC: B65B7/28
Filed: 1961-04-07
Abstract: 958,602. Seaming non-metallic sheet material. FARBWERKE HOECHST A.G. April 7, 1961 [April 8, 1960], No. 12663/61. Heading B5K. [Also in Division B8] A method of welding thermoplastic material comprises continuously heating a welding element 6, bringing the hot element 6 into contact with the material to be welded, pressing the element 6 against the material by means of a cooling element 11, withdrawing the element 11 from the element 6 and withdrawing the element 6 from the material. In the embodiment shown a lid 20 of synthetic plastic is welded on to a container 19 held in a mould 17 which has a silicone rubber, heat-insulating insert 18. The element 6 comprises a copper membrane and is heated by elements on a plate 5 to which it is clamped. In use, a device 1 is lowered to hold the lid 20 in position, the element 6 contacts and heats the portions to be welded and the element 11 comprising a water-cooled, annular jacket is brought into contact with the outer rim of the element 6 to exert pressure thereon. Welding takes place and after a time delay dependant on the material welded, the element 11, then the element 6 and finally the device 1 are raised so that the sealed container can be removed from the mould. The element 6 may be thermostatically controlled or, alternatively, if the plate 5 is made of an electrically-insulating material the element 6 may be directly heated by current supplied from a suitable regulator. A mica insulator 21 may be provided within the plate 5 but is not necessary when a current impulse is applied to the element 6. The invention may be applied to packaging machines to seal foils of cellulosic material coated with hydrophobic material or with polymers.

Title: Amplitude-and frequency-modulation radio receivers
IPC: H03D1/10
Filed: 1942-09-10
Abstract: 559,967. Frequency modulation; valve circuits for wireless reception. PHILCO RADIO & TELEVISION CORPORATION. Sept. 10, 1942, No. 12754. Convention date, Nov. 14, 1941. [Classes 40 (iii) and 40 (v)] In a receiver for the alternative reception of frequencymodulated and amplitudemodulated waves, the frequency discriminating detector for the FM waves is arranged, without switching operations, to function as a detector for the AM waves. The intermediate frequency circuits are arranged to be resonant to two different frequencies one for FM and the other for AM waves, and switching is confined to the radio frequency stages. In Fig. 2, the IF input to the discriminator includes two tuned circuits 8, 9 resonant to the respective intermediate frequencies. The FM wave is fed from circuit 8 to two untuned secondaries 1, 2 and a tuned secondary 3. These are associated with rectifiers D1, D2 in the manner usual in a phasing discriminator to give a difference output at A across the load resistances 6, 7 to the audio stages. The circuit 9 tuned to the lower AM wave is coupled to a circuit 10 connected only across the diode 2 and load resistance 7, and giving an audio output at A. Owing to the considerable difference between the two intermediate frequencies, each circuit 8, 9 acts substantially as a short circuit for the frequency to which it is not resonant. In a modified discriminator circuit, Fig. 3 (not shown), an AVC voltage is derived by additive combination of the voltages across the resistances 6, 7 in the manner described in Specification 559,535. The discriminator input transformers may be arranged as shown in Fig. 4, the FM input coil 8 being equally and closely coupled to the untuned coils 1, 2 and loosely coupled to the tuned coil 3. The AM coils 9, 10 are closely coupled to give one resonant peak at the working frequency, the other peak being well removed from that frequency. The coils mounted on an insulating tube 16, and the several condensers in the housing 17. The Specification also includes a circuit diagram, Fig. 5 (not shown) of a radio receiver embodying switchless detector and intermediate frequency circuits, together with the switching arrangements for the radio frequency stages . Specifications 181,799, [Class 40 (v)], and 489,094 are referred to.

Abstract: 1,224,748. Printing-apparatus. W. C. HELLER Jnr. 15 March, 1968 [27 March, 1967], No. 12787/68. Heading B6C. [Also in Divisions B2 and H4] An electrically insulating porous article such as a paper sheet 23, Fig. 1, is printed with electroscopic particles 24 to form an image by imposing an electric field between plates 20, 21 so that an attractive force is applied to the particles to move them on to and/or into the material of the article. The particles are of powder, including carrier particles selected to produce triboelectric charging, formed into a cloud by a generator 25. The plate 20 comprises an insulating base 20B supporting conductive portions 20-1, 20-0 shaped in image formation and connected to a voltage source 22. A control unit 26 first causes the cloud formation and then imposes an electric through-field so as to produce the image on the sheet 23. The upper plate, Fig. 1A (not shown) may be countersunk to prevent ringing &c. effects and one plate may be shaped to provide letterpress, Fig. 18 (not shown) or intaglio, Figs. 2-2C (not shown) types of printing process. Both stationary plates may be shaped in image formation, Fig. 1E (not shown). Stencilling apparatus.-A woven stencil 27, Fig. 1C, of insulating material is located between field plates 20, 21 and a cloud generator 25 supplies charged electroscopic particles to the gap between the stencil 27 and the plate 21, the paper sheet 23 being placed adjacent the plate 20. Off-set printing.-The sheet 23 may be of silicon rubber or polytetrafluorethylene and may act as an intermediate transfer sheet, the image which contains heat-softenable material being transferred to an article and fixed, in the ease of magnetic particles, by induction heating, or, in the case of thermoplastic particles, by flame heating. A patterned field plate 50, Fig. 3, of moulded epoxy resin may comprise wire-like members 50P embedded in closely spaced relation to define field poles energizable to produce electric fields extending from a scanning field plate 51 through an insulating print receiving sheet 23 on movement of the plate 51 and a wiper arm (52), Fig. 3B (not shown). The plate 51 is magnetic and acts as a brush. The image may be offset as described above. Duplicating.-A copy of an original 80, Fig. 5, may be produced on a sheet 81 using an optical image transducer unit 82 including an array of individual photosensitive elements 82P which between them span the whole of the image area. A field plate unit 83 includes a plurality of individual poles 83P each adapted to be energized, or not, by the corresponding photosensitive element, and a distributor 84 interconnects the unit 82 and the plate 83. A cloud of particles 24 overlies the copy sheet. Fig. 6 (not shown) depicts an articulated alternative embodiment. Multi-colour printing.-The apparatus of Fig. 5 may be modified to print in multi-colours, Fig. 12 (not shown), the original and copy sheets being fed linearly.
