IPC: H03K3/51
Filed: 1957-04-12
Abstract: 842,912. Converting. BRITISH THOMSONHOUSTON CO. Ltd. May 13, 1958 [April 12, 1957], No. 12068/57. Class 38 (2). An arrangement for providing unidirectional pulses comprises a pulse generator supplying pulses of opposite sense alternately and two pulsator pulse transformers, i.e. transformers whose cores exhibit a rectangular hysteresis loop and which are polarized for example by a D.C. bias winding. The two pulsator transformers P1, P2 are oppositely polarized so that on the advent of a positive pulse the transformer P1 is driven further into saturation whilst P2 is withdrawn from saturation and transformer action arises. On the negative pulse the transformer P1 operates. The winding senses of the primary and secondary windings are such as to provide unidirectional pulses at the output terminals. The windings may be on separate cores or a single three-limbed core. Specifications 666,574 and 666,575 are referred to.

Abstract: 481,062. Valve circuits for wireless reception. KRAMOLIN, L. L. DE. Aug. 29, 1936, Nos. 12430/37 (divided out of 470,945) and 23736/36. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 1, 1937.] [Class 40 (v)] In a radio receiver or the like in which the tuning of an oscillatory circuit is varied by means of a regulating current or voltage, means (not shown) are provided for preventing mains voltage fluctuations from affecting said regulating current or voltage. The regulating voltage may be amplified by a valve in the receiver which is provided. for another function, e.g. a local oscillator, and means may be provided for limiting the amplitude of the oscillatory output therefrom. The regulating voltage may be derived from an error detector and used for automatic fine tuning. As shown the anode circuit of the local oscillator 61 of a superheterodyne receiver is tuned by an iron-cored inductance assembly 39, 41, with trimming condenser 45, coupled to grid coils 38, 40, the circuits being tuned manually by variation of the current in the winding 48 of a magnetizing core 47. Automatic fine tuning is accomplished by deriving a correcting voltage from an error detector circuit 51, 52, 57, 58, 59 the off-tune circuits 51, 52 of which are coupled to the two halves of the split anode of the I.F. amplifier 50, the signal and A.V.C. detectors 55 being coupled to a common anode circuit 53. The tuning correction voltage is applied through coils 38, 40 to the grid of the oscillator 61 the controlled anode current of which flows through a winding 49 on the tuning core 47. A diode 62, biassed back by the cathode resistance 63, is incorporated in the valve 61 and connected across the oscillatory circuit 39, 41 to limit the amplitude of the oscillations produced therein. Wave-range switches 42, 43, 65 shortcircuit coils 40, 41 for medium wave reception and change over the trimming resistances 63, 64 which determine the bias on valve 61 and hence the oscillator tuning frequency. A switch 66 is provided to cut out the automatic tuning control and may be operated by movement of the tuning dial. Specifications 449,240, 451,097, [Group XXXVI], 451,098, and 470,945 are referred to. The Specification as open to inspection under Sect. 91 comprises also a mains voltage stabiliser in which the operating voltage is derived from a saturated and a gapped-core transformer with series-connected secondaries. This subjectmatter does not appear in the Specification as accepted.

Abstract: 353,456. Power meters. YOUNG, A. E., 1524, Asbury Place, Pittsburg, U.S.A. April 23, 1930, No. 12553. Convention date, March 21. [Class 37.] A part rotation proportional to the current play in a circuit, of a drum driven at constant speed is conveyed to a second drum and a part rotation of this drum proportional to the voltage is conveyed to a counter which h registers watts. Within a suitable casing 1 swing two levers 2, 22 in response to the voltage and amperage respectively of a circuit A, B. The levers are balanced by weights 32 attached to cord passing over pulleys and are slotted at their ends to carrv with relative longitudinal motion contact-pieces 3 which also are guided in vertical guides 4. Each contact-piece is adapted to engage in turn contact-strips 8, 9 on the drum 5 and 88, 89 on the drum 55. The drum 5 is driven from a motor 6 and the strips 8, 9 are so arranged that their distance apart circumferentially of the drum varies. When the contact 3 meets one strip the drum 5 is clutched to a drum 55 and when the other strip is met the clutch is released. The drum 55 is thus rotated for a time which varies with the amperage. Similarly the shaft 100 of a counter is arranged to be coupled and uncoupled with the drum 55 by engagement of a contact on the lever 22 with the strips 88, 89 and this variation being according to voltage, the counter 23 is operated according to watts. Slight discrepancies due to .the end of the lever having an arcuate movement and the contact a vertical straight line movement may be allowed for by a suitable shaping of the strip. Specifications 340,217, [Group XIX], and 353,418, are referred to.

Abstract: A fabric for making napkins is woven mainly from absorbent warp and weft yarns but has non absorbent warp yarns in an off-centre warpwise zone equal in width to the folded width of the napkin; the weave is such that the non-absorbent yarns predominate on the surface which is placed against the baby's skin.  The absorbent zones are folded on to the outside and secured by stitching.  The fabric has weftwise stripes of plain weave along which it is cut into napkins by pinking. Alternatively two or three layers (one of which has non-absorbent yarns on the outer surface) are joined by interweaving along warpwise and weftwise stripes along which the fabric can be cut and hemmed. The absorbent yarns are cotton or regenerated cellulose; the non-absorbent yarns are cellulose acetate or triacetate nylon, polyester, polythene, polypropylene, vinylidene cyanide, acrylonitrile, or vinyl chloride.

Title: A method of producing a highly porous, light and flowable sodium perborate
Inventor: PELLENS LUDWIG
IPC: C01B15/12
Filed: 1964-03-25
Abstract: Highly porous and flowable sodium perborate, having a bulk density of 0.25 to 0.45 kg. per litre is prepared by adding an aqueous solution of NaBo2 to an aqueous solution of H2O2 with stirring at 10 DEG  to 15 DEG  C.  The introduction of NaBo2 and H2 O2 is continued after crystallization begins to maintain a H2 O2: NaBo2 molecular ratio of 1.1 to 1.8.  When the desired degree of precipitation is reached excess H2O2 is reacted with further NaBo2.  A continuous process may be worked (as in the example) by periodically withdrawing portion from the reaction zone for further addition of NaBo2.  A lower bulk density is obtained when the H2 O2: NaBo2 ratio is higher.
