Patent GB-1353199-A (GB)
Title: Frequency distinguishing circuits for example for use in multifrequency telephone dialing systems
IPC: H04W88/18
Filed: 1971-06-30
Abstract: 1353199 Detecting presence of pulses; telephone dialling NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and FUJITSU Ltd 30 June 1971 [3 July 1970] 30764/71 Headings H3T and H4K [Also in Division G4] A. signal frequency receiver for distinguishing one out of four possible frequencies has band pass filters BS11-BS14 defining the channels followed by pulsing stages DET11-DET14 which convert the distinguished signal to a pulse train for input via an OR gate to one input of an AND gate, the other input of which comes from a circuit RC11 providing a steady output for the duration of a pulse train from any channel; by virtue of the feedback from the AND gate to the OR gate a continuous identifying signal is provided at the output of the AND gate for the duration of the pulsating signal on the pulsing stage DET. The invention avoids the use of large smoothing capacitors in all the channel output stages. A pair of such signal frequency receivers may be provided for receiving a combined signal of two frequencies selected one from each of two groups of frequencies; two broadband pass filters initially separate the two groups of frequencies. The output of the circuits RC11 of both receivers passes to a coincident circuit which tests their coincidence for a predetermined duration before priming the AND gates. In a signal frequency receiver a circuit (Fig. 3) is employed in which in the presence of a negative going pulse train at input 31, NAND gate 32 provides a steady output at 33. During the zero potential pulses, diode D maintains the input to inverter INV at zero potential, against capacitor C tending to drive it negatively, so providing a positive output from the inverter, enabling NAND gate to open in response to the zero pulses to provide a positive output at 33. During the positive inter-pulse spaces capacitor 3 drives the inverter input positive so providing a zero output on the inverter to maintain the NAND gate open. In another arrangement (Fig. 5, not shown) positive going pulses are applied to an OR gate and during the zero inter-pulse spaces a transistor maintains the OR gate open.

Patent GB-356975-A (GB)
Title: Improvements in making artificial silk
IPC: D01D10/04
Filed: 1930-10-20
Abstract: In a continuous process of producing and after-treating artificial silk, the freshly precipitated threads are drawn off from the spinning bath and then passed through a series of treating baths in a parallel position and in an unstretched state by means of rotating guiding devices such as rollers the velocity of which is adjustable. The treatment is carried out in such a manner that the thread is not subjected to mechanical stress such as bending, stretching, or pinching before being wound on the receiving device.  In treating viscose silk, the speed of spinning may be from 50 to 100 metres per minute and the time of treatment may be less than one minute.  As shown in the drawing, freshly prepared bundles of artificial silk from a number of spinning nozzles are drawn out of the spinning bath under tension and slightly bent at the thread guides b.  The drawing roller c passes the threads into the bath e1 from which they are taken up by the roller f1 and passed into the bath e2.  The threads are similarly passed by rollers f2, f3, &c., <PICT:0356975/IV/1> <PICT:0356975/IV/2> into the baths e3, e4, &c.  The speed of each of the rollers is adjusted so that in spite of changes in the length of the threads, the latter are guided through the baths with substantially constant sag.  Each of the baths is provided with a number of hooks i under which the threads are passed, and which serve to keep the threads under the level of the liquid in the bath, but do not subject them to tension.  The various baths may contain liquids for washing, desulphurizing, soaping, and otherwise treating the material.  In the case of cuprammonium silk a bath for removing copper is provided.  The threads leaving the last bath are led over roller h or passed over a drying device, and then received on a collecting device l which may be constructed as a drying device and provided with interchangeable spools, bobbins or canettes m.  The artificial threads thus treated have a good lustre and tenacity and exhibit even dyeing properties.  The fibres of the untwisted bundles adhere without the application of a sizing agent and can be worked into textile products without twisting.  Specification 311,399, [Class 2 (ii), Cellulose &c.], is referred to.

Title: Electric heater element
IPC: H05B3/06
Filed: 1974-07-16
Abstract: 1482286 Resistance heating element EMERSON ELECTRIC CO 16 July 1974 [12 Nov 1973] 31472/74 Heading H5H [Also in Division E2] To prevent sagging of a heating resistance coil 8 which is supported intermittently throughout its length, expansion of the coil 8 is prevented by spring clips 7 mounted on flat spaced insulators 10 provided with U-shaped notches 17 to seat turns of the coil, the spring clips 7 each engaging a turn of the coil 8 thereby limiting longitudinal expansion. Each insulator 10 is either in the form shown in Fig. 2 with two oppositely directed notches 17 to locate turns of two heater coils 8, or in a form with only one notch 17 (Fig. 3, not shown) to locate the turns of one heater coil 8. The insulators 10 are inserted in spaced holes 25 in channel section beams 5 and are retained therein by tabs 26 of the beams 5 engaging central openings 15 in the insulators 10. Pairs of grooves 18, 21 at opposite ends of insulators 10 co-operate with tabs 40 in the side walls 28, 29 of clips 7 to retain them in position. Each clip 7 is rectangular in plan having a discontinuous back wall 30 and a front wall 27. Front wall 27 has a vertical slot 32 extending from top edge 50 to an elongated aperture 33. Flanges 34, 35 are formed on either side of slot 32. The upper parts 36 and 38 of flanges 34, 35 respectively are twisted in opposite directions from the plane of wall 27 and the lower parts 37, 39 are twisted in opposite directions from the plane of wall 27, the upper and lower parts of each flange being twisted in opposite directions. This ensures that the width of the slot 32 at the top is bigger than the diameter of the wire of the coil and the width at bottom of the slot is smaller than the wire diameter. When a coil turn is introduced through slot 32 to the elongate aperture 39, the lower parts of flanges 34, 35 are forced apart by the wire to allow it to enter aperture 39. Once in the aperture 39, the wire is trapped between the upper edge of aperture 39 and the notch 17 in insulator 10 and its removal is prevented by the lower parts of flanges 34, 35 which return to their initial position. The metal clip 7 acts as a heat dissipating fin and in conjunction with its open ended insulator 10 scarcely shields the heating coil at all, thereby obviating local overheating. The beams 5 are supported between transverse support structures 3, 4 which are in turn secured to a front panel 2 carrying controls 9 which control the output of the stack of heater coils 8.
