Title: Method of transferring photographs made on stripping films
IPC: G03C11/12
Filed: 1937-11-26
Abstract: 510,233. Photographic stripping processes. HARTMANN, H. SCHMITZ-. Nov. 26, 1937, No. 32641. [A Specification was laid open, to inspection under Sect. 91 of the Acts, May 30, 1938] [Class 98 (ii)] A finished photographic picture layer on a support having a softenable intermediate layer to facilitate stripping, is pressed in moist condition on a dry final support having a fabric ground impregnated with a water-soluble dressing such as starch which becomes tacky when moistened. Heat up to 90‹C. may be applied before stripping off the original support. As final supports may be used non-transparent bookbinding linen or calico or tracing cloth having a ground of linen, cotton wool, cellulose wool, or silk. The original may be produced by direct photography, enlargement, or contact printing, particularly reflex contact printing. If the final support is sufficiently transparent, the transferred picture may be printed from. Reference is made to known stripping papers with intermediate layers of gelatin or glue soluble in water, or of resin or caoutchouc soluble in benzine or spirits of wine; to known final supports of ceramic materials, metals, wood, paper, and leather which require the application, to the final support or to the layer to be transferred thereto, of an adhesive before the transfer operation ; and to a known method of transferring by moist heat treatment a picture layer, formed directly on a support without an intermediate stripping layer, to a document having a fabric ground.

Title: Direction finders
IPC: G01S3/52
Filed: 1945-12-03
Abstract: 622,822. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 3, 1945, No. 32648. Convention date, May 20, 1943. [Class 40 (vii)] A direction-finding system comprises an aerial such as a vertical dipole 1 or horizontal loop continuously rotated in a closed circular path about a central axis 7, whereby signals picked up are phase-modulated at the frequency of rotation, a variable radio-frequency oscillator 23, Fig. 3, of frequency substantially the same as that of the received signals, a fixed-frequency oscillator 31 supplying oscillations at a desired intermediate frequency, a balanced modulator 29 fed by oscillators 23, 31, a modulator 27 fed with the received signals and with the output of balanced modulator 29 to supply an intermediate frequency to filter 33, a frequency-control circuit 35 fed with the output of filter 33 and with oscillations (through a 90 degrees phase-shifter 37) from oscillator 31 to maintain the frequency of oscillator 23 the same as that of the received signals, a detector 39 fed with signals from filter 33 and with oscillations from generator 31 to provide a low-frequency signal having a frequency equal to that of rotation of the aerial and a phase determined by the angle of incidence, and a phase-comparator for comparing the phase of this low-frequency signal with that of a reference signal supplied by a generator 97 driven in synchronism with the aerial. The phase-comparator comprises two multi-electrode values 51 and 53 in push-pull, the outputs of the valves being connected to the respective terminals of a reversible electric motor 101 driving the movable member of a variable phase-shifter 77 of the bridge-network type. The output of the rectifier 39 is fed to the outer control grids of valves 51, 53 whilst the reference alternation is fed through the phase-shifter 77 to the inner grids. With this arrangement, when the two input voltages are in quadrature, valves 51, 53 conduct during equal portions of each cycle so that, owing to the integrating effect of the capacitors 63, 65, the voltages developed across the resistors 55, 57 are equal and the resultant voltage applied to the motor 101 is zero. For any other phase-angle between the two input voltages, one of the valves will conduct during a greater portion of each cycle than will the other, producing a difference voltage which causes the motor to run in one direction or the other and drive the phaseshifter 77 accordingly. The phase of the input to the inner control grids of the valves is thus changed until a quadrature relationship is reached. To indicate azimuth, an indicator 105 is connected to the shaft driving the phaseshifter 77. The equipment associated with the antenna is mounted in a housing 11 and power may be supplied by a generator on a shaft 13 geared to the driving motor 19. The indicating equipment may be at the foot of the tower 9 and controlled from the housing 11 over a microwave link. Specification 592,570 is referred to.
