Title: Transfer method for the application of an authenticating seal to documents and other appropriate articles
IPC: B44C1/175
Filed: 1946-04-12
Abstract: 615,666. Transfers. SOC. DES PROCEDES SERGE BEAUNE. April 12, 1946, No. 11346. Convention date, June 15, 1944. [Class 100(ii)] [Also in Group XV] A method for the application of an authenticating seal to documents or other appropriate articles consists in imprinting a seal marking of thick ink on the inner face of an adhesive transparent film which is then applied by transfer to the article in such a way that the marking is sealed between the article and the film so as to prevent falsification. The seal marking is printed with monochrome thick ink or by polychrome printing processes on the gelatined side of a transfer paper provided with a layer of about 12 per cent concentrated gum arabic, the gelatine being of about 10 per cent concentration. The transfer is dipped into 6 per cent acetic acid and applied with the gelatined side against the document, the marking thus being under the gelatine film. Adhesion is perfected by a rubber roller, and the gummed paper removed by softening with cold water and lifting off with its paper support. The film R is applied to a photograph P and mounting S. The characters on the seal are translucent. The film may be colour printed, as by the process described in Specification 610,943. The films R may have sinuous or broken edges, and may be coloured. The transfer paper may have perforations provided, and may have a marginal edge without gum or gelatine to facilitate the transfer. An outer seal may also be placed partly on the film and partly on the free part of the document.

Title: Compensating for gimballing errors in a direction defining instrument
IPC: G01C19/38
Filed: 1964-03-18
Abstract: 1,057,743. Gyroscopes. SPERRY RAND CORPORATION. March 18, 1964 [March 18, 1963], No. 11361/64. Heading G1N. In a gyroscope 10, Fig. 1, having a rotor 14 defining a reference direction 18, and being mounted for example on part of an aircraft 16, to sense horizontal angular displacement of the aircraft about a vertical axis (1. e. change of heading), gimballing errors introduced by an additional rotation of the aircraft about the fore and aft axis (i. e. roll) are compensated for by measuring the roll angle with a vertical gyro 50, the gimbal 51 of which is pivoted about the fore and aft axis and using this signal to modify, at 48, the heading signal. The heading signal from gyro 10 is transmitted from a selsyn 23 to a selsyn 30, at least one of the phase signals being modified by the correction signal. The angular position in the roll-produced inclined plane of the gimbal 10 relative to the aircraft fore and aft axis, differs from the angular position which would exist in a horizontal plane by an amount which varies generally sinusoidally with the roll angle #. The roll angle # signal is therefore modified by a cos # generator 60 to allow for this, the cos # signal being used to vary the gain of an amplifier 48, which is fed by a voltage developed across one arm of a resistor network 42, 43, 44 star-connected across the selsyn connections 20, 21, 22. The amplifier output signal may alternatively be supplied to the primary of a transformer whose secondary is series connected in the line 20, Fig. 2 (not shown).

Filed: 1939-04-18
Abstract: 527,659. Making compound plates. ORR, J. B. April 18, 1939, No. 11688. [Classes 83 (ii) and 83 (iv)] Rolling.-In welding a layer of stainless steel to a plain steel plate by pack rolling or working a sandwich of stainless steel plates 2 between carbon steel plates 1 sealed by strips 5, a hole or holes 6 of size calculated by given formulae is made in the pack so as to allow some of the gases (carbon-monoxide) formed in the pack to escape and so prevent bursting and dangerous combustion of such gases and yet small enough to prevent ingress of atmospheric oxygen. The stainless steel plates 2 are separated from each other by some weld preventing material, and are separated from the outer plates by weld enhancing material, e.g., carbon black so that when separated at the middle the finished articles are composite steel plates faced by stainless steel plates. Each hole is made larger than required and then is swaged in round a wire of the exact size which is then withdrawn. The carbon black when heated absorbs any oxygen in the pack and acts as a reducing agent. The vent hole may be at the tail end and may be closed by the rolling. The tail end may be cut off and the pack then re-rolled. U.S.A. Specifications 2,160,558 and 2,160,559 are referred to.
