IPC: H04N1/00
Filed: 1965-04-30
Abstract: 1,111,671. Monitoring facsimile telegraph signals. FERNMELDEWERK ARNSTADT VEB. 30 April, 1965, No. 18285/65. Heading H4F. In an arrangement for monitoring facsimile telegraph signals, the signal voltage is applied at terminal E1 and utilized via a keying circuit 5 to effect " on "-" off " control of the beam of a long-persistence cathode-ray display tube 1 scanned with a rectangular raster by means of a horizontal scanning generator 3, controlled by the synchronizing signals produced at each rotation of the transmitter drum and fed to terminal E2, and a vertical scanning generator 4 of adjustable frequency lower than that of generator 3 by a factor of ten to one hundred. Adjustment of the relative sweep frequencies allows desired dimensional conditions, e.g. enlargements, to be produced and to ensure the production of an easily interpreted display, a polarity reversing switch 9 permits the reproduction of a photographic positive display should " negative" type signals be transmitted and a second polarity reversing switch 8 allows lateral inversion of the display should a mirror-image be transmitted. The monitoring may be effected on the transmitted or received signals.

Abstract: 1,270,213. Heatable snubbing pin. GLANZSTOFF A.G. 17 April, 1970 [19 April, 1969], No. 18440/70. Heading B5B. A fixed, heatable snubbing pin suitable for use in the stretching or heat setting of filaments comprises a cylindrical metal pin 6 surrounded by a replaceable ceramic or metal sleeve 7 wherein the sleeve is held in place by means of a cylindrical resilient element, preferably a basket spring 13 (Figs. 1 and 2) or a tolerance ring 22 (Fig. 3). The metal pin 6, which consists of two sections 10 and 11 of different diameters, is fixed to a frustrum 3 by means of a screw 9 and may be heated by a heating medium flowing in the pipe 2 to which the frustrum 3 is welded. The basket spring 13, which comprises sprung strips 15 separated from one another by incisions 16 and a slot 17 extending over its entire axial length, or the tolerance ring 22, which consists of circular sprung sections 23, bent in the form of waves, and a similar full-length slot, surround the section 11 of the pin 6 defined by the collar 12 and the end face 14 of section 10. When the sleeve 7, whose internal diameter is smaller than the external diameter of the expanded element 13 or 22, is pushed on to the pin 6 over a basket spring 13 or tolerance ring 22 it reduces the diameter of the element, and correspondingly increases its length, so that the compressed section of the element bears against the bore of the sleeve and thus holds it in position on the pin. Section 10 of the pin 6, which is not covered by the replaceable sleeve, is surrounded by an insulating jacket 18 to increase heat transfer between the heating pipe 2 and the surface of the stretching or heat setting pin.

Magnetic instruments; diaphragms.- A device for converting mechanical vibrations into electrical vibrations and vice versa by electromagnetic induction, more particularly for use as a telephone transmitter, receiver or loudspeaker, comprises a magnetic circuit, a portion of which is constituted by one or more bodies consisting, at least in part, of magnetic material, and supported solely by the magnetic field. In its simplest form, a magnetic air gap is partially bridged by a body in the form of a thin lamina of magnetic material. The body or bodies may be constituted by magnetic material or by non-magnetic material coated with magnetic material. A modified construction is described in which a portion of the magnetic circuit is constituted by finely divided magnetic material substantially unsupported excepting by the magnetic flux. In a further modification, the finely divided material may be supported upon a membrane between a pair of magnet poles so as to be substantially unconstrained in the direction of its vibrational movement. The material may either be attached to the membrane by an adhesive or deposited thereon in colloidal form. In the construction shown in Fig. 1, the electromagnet 1 is excited by a coil 2 and is provided with pole-pieces 3, the air gap between which is bridged by finely divided magnetic material 4, which constitutes a substantially aperiodic diaphragm. The material 4 may be supported on or enclosed in a thin material so that it remains in position when the magnetizing current is interrupted. Pick-up coils may be provided on the magnet limbs or the polarizing coil 2 may serve as the pick-up coil. In a modification, the material 4 is situated in the annular air-gap of a pot-shaped magnet. In order to prevent resonance, the air chamber behind the diaphragm, where this exists, may be provided with apertures communicating with the outside air and damping material, such as cotton wool, may be inserted in the chamber.

Title: Improvements relating to mechanism for feeding paper sheets and the like
IPC: B65H3/06
Filed: 1926-07-27
Abstract: 279,545. Goffin, S. F. H. July 27, 1926. Sheet separators and carriers; grippers.-A sheet-feeding mechanism for feeding sheets to or through addressing or other printing machines is constructed with a gripping-member consisting of a reciprocating slide b having a roughened rubber or serrated metal face a adapted to engage the sheet over the major portion of its length along one side only parallel to the direction of feed. The slide b is reciprocated by a link C and mechanism which permits of adjusting the extent of motion, and it is mounted so as to be adjustable laterally, and is guided by slots engaging rollers v on a fixed frame member H. When feeding from a pile, the top sheet is separated by an intermittently rotatable triangular roller P which is formed with three friction surfaces t acting to buckle the top sheet when the pile is engaged by the gripping-surface a, and as the slide b moves towards the machine the arched sheet passes over a stop N which prevents double feed. A pivoted bail S with spikes s maintains the sheet in arched form until it is advanced over the stop N. The separated sheet is gripped between the slide b and a spring- pressed plate D, and moves forward until a holdfast strip B is depressed by a link E, Fig. 2, lever F, and a spring h which is put in extension on the forward movement of slide a and in compression on the return movement. The link E is held by a latch K to hold the strip B raised until a pin m on the slide b acts on an adjustable stop L to release the latch K and allow the strip B to press the sheet against the plate D, as shown in Fig. 5, while the slide b returns. On the return of the slide b the spring h is compressed and acts on lever F tending to raise the bold-fast strip B A catch J engages link f to prevent the strip from rising until the pin m acts on an adjustable stop M to release the catch J. When used for listing, the sheet is fed forwards a distance corresponding to the space between successive impressions of the listing- machine. The gripping-device may be arranged to act on the underside ot a sheet, and sheets may be fed from the bottom of a pile. Double feed may be prevented by a reversely rotating roller, or by a rubber surface on the bottom of the sheet-magazine.
