Title: A process for making a sponge-like heat and sound insulating material from textile scraps
IPC: C08J9/08
Filed: 1955-04-19
Abstract: Sponge material for heat and sound insulation is prepared by dissolving polyamide or polyamide and woollen scrap in a concentrated aqueous solution of acid, spreading the dissolved mass on a support in a thin layer, and treating the mass with an alkali metal carbonate solution.  In one example (1) part by weight of polyamide fibre scrap is dissolved in 2.3 parts hydrochloric acid solution, density 1.15. Undissolved particles are removed by straining, and the viscous solution is spread on a glass plate as a layer of 0.8 to 1.2 mm. thickness and treated with sodium carbonate solution of about 1 molar strength at 80 DEG  to 100 DEG  C. to produce foaming.  The expansion of the layer is limited by a wire mesh or a perforated plate disposed 10 to 15 mm. from the glass plate.  The sponge thus formed is washed and dried. In a further example, formic acid is used instead of hydrochloric acid.  In another example, the scrap solution comprises a mixture of solutions obtained by separately dissolving 1 part by weight of woollen scrap and 1 part of polyamide fibre scrap in 2.3 parts of hydrochloric acid solution, density 1.15.  It is also stated that nitric or sulphuric acid may be used for dissolving the scrap, and that the sponge material may also be prepared from a mixture of an acid solution of polyamide fibre scrap and a suspension of glass wool.ALSO:Sponge material for heat and sound insulation is prepared by dissolving polyamide or polyamide and woollen scrap in a concentrated aqueous solution of acid, spreading the dissolved mass on a support in a thin layer, and treating the mass with an alkali metal carbonate solution.

Title: An improved method of and apparatus for measuring and/or controlling width variations of longitudinally moving metal in strip or other elongated form
Inventor: WILLIAMS NORMAN THOMAS
IPC: B21B38/04
Filed: 1949-04-28
Abstract: 670,035. Determining physical qualities of materials by electric tests. STEWARTS & LLOYDS, Ltd. May 22, 1950 [April 28, 1949], No. 11290/49. Class 37. The edge of a longitudinally moving strip S, Fig. 1, of metal, e.g. hot rolled steel strip, varies the capacity of a condenser to provide a signal proportional to the width of the strip for measuring or control purposes. Preferably two pairs of condenser plates A, C and B, D, Figs. 1 and 2, one pair at each edge, are used so that sideways movement of the strip does not affect the total capacity C<SP>1</SP>. To avoid variation of capacity due to expansion of the plates with temperature, each plate, e.g. A, Fig. 2A, is constituted by two plates A<SP>1</SP>, A<SP>2</SP>, with the edges A<SP>4</SP> fixed and the edges A<SP>3</SP> overlapping and free so that the expansion does not vary the area of the combined plates. Measuring capacitance.-The varying capacity C<SP>1</SP>, Fig. 3, is connected in the tank circuit of an oscillator, a standard condenser C<SP>2</SP>, CT being in the tank circuit of an identical oscillator. When the capacity C<SP>1</SP> is equal to C<SP>2</SP>+CT, the oscillators have the same frequency and are in phase, so that no current flows in the link circuit L<SP>1</SP>, L<SP>2</SP>; when C<SP>1</SP> differs from C<SP>2</SP>+CT, the frequencies developed by each oscillator remain identical, since the link circuit locks the oscillators, but the oscillations become out of phase, and a current flows in the link circuit ; this current is rectified and applied to the meter M, control signals being taken off at X.

Abstract: 684,949. Electric remote control. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946 [April 18, 1945] No. 11328/46. Class 40 (i) [Also in Group XL(c)] In a radio system suitable for the remote control of a glider, a transmitted carrier wave is modulated by a selected one of a number of pulse-modulated sub-carrier waves. By using pulses, more power is available and detection is more difficult. When one of the glider controls is to be operated or its controls restored to normal by one of the relays 5 ... 9, a control lever 3 energizes relays to produce one or more pulses at 10 and to insert one of five inductances in the circuit of an oscillator 12. Sub-carrier and principal oscillators 12, 18 are keyed by the pulse generator 10 and the oscillator 18 is plate-modulated by the output from 12. The modulated principal carrier wave is radiated from a broad band aerial 20 received by the glider aerial 21, amplified in a broad band amplifier 22, and fed to a detector 23. The output from 23 is fed through a high pass filter 24 and amplifier 25 to five separate channels 26 . . . 30, each comprising a selector filter 31 designed to pass one of the five sub-carrier frequencies. The output from a selector filter is fed through a threshold clipper 32 and an integrator 33 to the required relay. The Specification suggests 200-microsecond pulses, subcarrier frequencies within the 1-2 or 2-3 megacycle band and a principal carrier frequency of several hundred megacycles.
