[Class 140.] A sheet of fibrous material impregnated with a non-hardening, thermoplastic, synthetic resin is united by pressure to a metal sheet. The fibrous sheet may consist of one or more layers of canvas, duck, paper, asbestos paper or cloth, &c. impregnated with resin such as aniline-formaldehyde resin, coumarone, or vinyl compounds such as styrene, the layers being united together before or simultaneously with their union with the metal sheet. Suitable cements for joining the metal to the fibrous sheet are a solution of rubber and phenolformaldehyde resin, reaction products of rubber and sulphuric acid or a sulphonic acid such as benzyl sulphonic acid, polybasic acid-polyhydric alcohol resins, or asphalt or bituminous compositions containing if desired fillers or softeners. The upper resin-impregnated fibrous sheet may be coloured or patterned e.g. to imitate wood, and a final coating of a resin having a high finish such as phenol- or ureaformaldehyde resin, or a sheet of fibrous material such as paper impregnated with such resin, may be superposed. A compressible layer such as felt, paper, cloth, cork, or asbestos may be interposed between the impregnated fibrous material and the metal sheet, and this layer may be impregnated as well as coated, with the cement. The aniline-formaldehyde resin may be incorporated in the paper &c. sheets as described in Specifications 342,326, and 368,300. The material can be bent, stamped, or cut, preferably after heating by immersion in hot water, and is used for making furniture, window or door frames, motor-car bodies, tubes &c. The Specification as open to inspection under Sect. 91 describes also the use of natural resins such as shellac, copal, manilla, and acaroid resin for impregnating the constituent layers of the fibrous sheet.

Title: Improved process for the manufacture of synthetic tanning substances and method of tanning skins therewith
IPC: C14C3/20
Filed: 1931-10-16
Abstract: Synthetic tanning agents are made by condensing with sulphonated phenols, cresols or naphthols or aromatic hydrocarbons, the sulphuretted products resulting from the combination of urea with sulphines, e.g. pentamethylenediamine-di-sulphine, i.e. the products obtained by causing an excess of ammonium sulphide, polysulphides or hydrosulphide or sulphocyanides of ammonium or calcium to act on aldehydes.  The products may be partially neutralized with metal oxides or hydroxides.  They show the usual reactions of tannins and precipitate basic colouring matters.  They may be employed in the liquid or dry state and brought to a suitable acidity by adding solid organic acids, acid mineral salts or other acidic substance.  In examples (1) and (2) formaldehyde, urea and ammonium sulphide are condensed together and the product treated with a sulphonated m-p-cresol mixture, or with a naphthalene sulphonic acid; (3) sulphonated phenol is condensed with the product from urea, formaldehyde and ammonium polysulphide.  An example of the tanning processes is also given.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of thiourea and other carbamides as starting materials.

Title: Improvements in and relating to instruments for the measurement of di-electric dispersion of electrical insulation
Inventor: BERGER BRUNO
IPC: G01R31/14
Filed: 1960-08-19
Abstract: 989,097. Measuring dielectric dispersion; valve voltmeters. C. A. PARSONS & CO. Ltd. July 31, 1961 [Aug. 19, 1960], No. 28863/60. Heading G1U. [Also in Division H3] The instrument for measuring dielectric dispersion disclosed in Specification 701,862 (Fig. 2) is modified in that two separate battery operated power sources are used with D.C.-D.C. converter step-up voltage means. Power source 1a normally charges a capacitor 2 over a switch 3. When this switch is moved to the "test" position 3c the charge on capacitor 2 triggers a pulse generator 4 which delivers a 3 m. sec. pulse over a diode gate 5 and double screened cable 7 to the test object 6, the shunt capacitance C 0 , Fig. 1, (the equivalent circuit of the test object) of which is charged to the pulse voltage V 0 . A time marker pulse generator 11 is also triggered by the capacitor 2, 300 m. secs. later to render the valve voltmeter input stage 8a operative to charge a capacitor 10 over a diode 9 to a voltage proportional to the voltage V 1  across the test object 6 after this delay. The voltage-drop to V 1  arises, apart from leakage,from dispersion of the charge on C 0  to the series capacitance C S  of the test object, the time constant of the C S -R S  series combination being long relative to 3 m. secs. but short relative to 300m.secs. The dielectric dispersion is defined as V 0 -V 1 /V 1  but as V 0  is constant the meter 15 measures the voltage across capacitor 10 and hence V 1  and may be calibrated to read percentage dispersion. A pen-recorded may be used instead of meter 15 in which case the switch 3 is sequentially operated automatically. The second power source 1b is used for the valve voltmeter stages 8a, 8b and the diode gate 5 which applies the 3 m. sec. charging pulse also to the inner screen 7a of line 7 to ensure very high line impedance. Valve voltmeter, Fig. 4. The voltage V 1  is applied over a cathode follower V 4 , having its screen stabilized by a Zener diode, to a normally blocked cathode follower V 5  which conducts only when the pulse generator 11 pulses its screen grid. Then a voltage proportional to V 1  appears at Y and charges capacitor C 6  (10 in Fig. 1a) over a diode D 8  to "freeze" this voltage in spite of further decay of the test object voltage. The voltage on C 6  is fed over cathode follower V 6  to a balanced silicon transistor amplifier TR 1 , TR 2  which allows the meter to be calibrated directly in percentage dispersion. The meter is zeroised by adjusting resistor R 10  when a standard capacitor 13, Fig. 1a having zero dispersion is connected by switch 3 (zeroising position) in the test circuit instead of test object 6. Variations of amplifier gain with ambient temperature variations is effected by a temperature sensitive resistor TH 1 .
