Title: Improvements in or relating to transfer materials
Inventor: HARWOOD RONALD WILLIAM
IPC: B44C1/175
Filed: 1951-08-09
Abstract: 723,776. Transfers. OMEGA PLASTICS, Ltd. Aug. 8,1952 [Aug. 9, 1951], No. 18821/51. Class 100 (2). A transfer material consists of a film backing layer carrying a design printed wholly or in part in fluorescent ink, the areas in fluorescent ink being under-printed with a highly reflective layer of light-coloured or white pigment or pigment of substantially the same colour as the ink or the backing layer, the assembly of film and design being secured by a removable or destructible adhesive layer to a temporary support. The reflective under-printing increases the fluorescent effect of the fluorescent ink. The adhesive and support may be secured over the design or to the opposite side of the backing layer, and consequently the design will be buried in the transfer material or be an outerface thereof respectively. The backing layer may be a layer of any cellulose or oil colour paint, or a clear cellulose lacquer or oil varnish. The under-print may comprise any white or light-coloured ink or paint, enhanced by the inclusion of a small proportion of a bluefluorescing substance, an optical bleacher. The under-printed areas may be greater than the areas printed in fluorescent ink. The fluorescent inks may consist of those known as "Noonink" or under the Registered Trade Mark "Dayglo," or similar inks. The adhesive may be soft gelatine or glue which can be removed by immersing in water, or gum dammar, which can be broken by pulling apart. The temporary support is preferably flexible and usually paper. Adhesion to the permanent support may be effected by the remains of the original adhesive or with fresh adhesive. The quality of the product can be improved by providing a clear colloid protective layer such as a clear cellulose lacquer over at least the fluorescent ink areas in the transferred material. This layer can be applied to the face of the transferred design, or may form part of the original material, lying between the fluorescent ink design and the adhesive or as a supercoat on the design according to the form of material used.

Title: Gyro stabilized compass
Inventor: MCKINLEY PAUL A
IPC: G01C19/36
Filed: 1954-06-29
Abstract: 769,442. Gyro-compass systems. COLLINS RADIO CO. June 29, 1954, No. 19069/54. Class 40 (1). [Also in Group XX] A gyro-magnetic compass comprises a free directional gyroscope 10, a synchro-transmitter 28 with a rotatable stator 31 and a rotor 27 mechanically connected with gyroscope 10 and connected to an electric power supply, a pair of synchros 42, 72 the stators of which are connected to the stator of the synchro-transmitter, and an indicating means 78 connected to the rotor 74 of synchro 72 is characterized in that a free magnetic compass element 38 is mechanically connected to the rotor 41 of the synchro 42, and a driving means controlled electrically by the voltage in the rotor 41 is mechanically connected to rotate the stator 31 of the synchro-transmitter so that the rapid fluctuations inherent in the magnetic compass element are not followed, but that the drift of the free gyroscope is corrected. The electrically-driven rotor 18 is mounted in the craft in gimbals 15, 11, and its spin axis is maintained substantially horizontal in known manner. The outer gimbal 11 is geared to the rotor 27 of the synchrotransmitter 28. The output of the rotor 41 of the servo-resolver 42 is fed to a servo-amplifier 47 connected to a motor 48, which drives the stator 31 of the synchro-transmitter through a gear train which includes a two-speed gear-box 58 controlled by a relay 66. The synchro resolver 72 controls the position of the pointer 78, which indicates the heading of the craft. In operation, the gyroscope rotor is started up and erected. The gear-box 58 is in high-speed position so that stator 31 of the synchrotransmitter is quickly adjusted by the errorsignal induced between its windings and those of the stator of servo-resolver 42 and applied to the servo-amplier 47. The gear-box is then shifted to its low-speed position. Thereafter the error signal keeps the stator 31 in step with the average position of the magnetic element 38. Low-frequency oscillations of the gyroscope are integrated by the tracking of motor 48, and high-frequency oscillations of the magnetic element are integrated by the high gear ratio.
