Title: Tone correction of photographic image
IPC: G03B27/72
Filed: 1956-03-16
Abstract: 799,590. Tone correction of photographic images. AGFA AKT.-GES. [formerly AGFA AKT.-GES. FUR PHOTOFABRIKATTON.]. March 16, 1956 [March 19, 1955], No. 8331/56. Drawings to Specification. Class 98(2) A black and white or a monochromatic normal photographic image is combined with a coloured tone-correcting mask of colour different from that of the normal image, image and mask being either both positive or both negative, and these are copied by printing light absorbed by the normal image and usually partially absorbed by the mask on to a photographic layer sensitive to the light employed, whereby the light partially absorbed by the mask can be chosen to print the latter in desired gradation. The pair so printed may be separate or inseparably combined and printing may be in one step or separate steps for image and mask. In Example 1 a green-sensitized gelatino-silver bromide emulsion containing a specified magenta coupler on a transparent support is overcoated with a silver halide layer of 1/20th sensitivity of that of the inner layer and which is not optically sensitized but contains a specified yellow coupler, and this material is exposed in a camera to a black and white continuous tone image, colour developed, bleached and fixed with production of magenta image and yellow tone-correcting mask of specified relative gradations and printed on to an orthochromatic layer in two steps with blue and green printing lights respectively. The same effect can be achieved if the inner layer does not contain a coupler and the material is not bleached after development but only fixed, to produce silver and silver plus dye images respectively. Example 2 indicates production of a black and white silver image and a separate magenta coloured high-light image from a black and white continuous-tone image on a paper support, registration of the images so produced and printing thereof on to orthochromatic material as in Example 1. In Example 3 a multicolour negative is printed through a green filter on to two sheets of orthochromatic material, one of these is developed to form the normal black and white image and the other, of short exposure, is developedd to cyan, and these images are registered and printed through a screen on to a panchromatic layer using red and green filters successively, to result in copy for the production of a printing plate for the red partial image of multicolour printing. Example 4 describes production of a yellow high light image on a diazo layer from a black and white diapositive, registration of such with its original and printing or to carbon tissue.

Abstract: 1,121,376. Presses. L. SCHULER G.m.b.H. 22 Feb., 1967 [4 March, 1966], No. 8501/67. Heading B5F. In a press having a shaft arranged to be braked by discharging a compressed air cylinder 1, the pressure reduction of the compression air during normal braking is slow relative to that for an emergency stop. The pressure reduction for normal and emergency stops may be the same until the brake becomes effective. In one example (Fig. 2), during an emergency stop a valve 5 with a larger flow cross-section 6 is used to exhaust the cylinder 1 and allow a spring device to apply the brake. During a normal stop a valve 8 is used and a counter pressure is built up in an air vessel 10 to slow down the pressure reduction in the cylinder 1. An outlet 11 for the vessel 10 may be open or closed. In Fig. 3 (not shown) the vessel 10 is dispensed with while in Fig. 4 (not shown) a single valve (23) is used with an outlet (24) the cross-section of which can be varied by an insert (26) which is movable by an hydraulic or electromagnetic device 25.

Title: Improvements in or relating to mercury arc rectifiers
IPC: H01J13/32
Filed: 1932-03-23
Abstract: 399,195. Mercury-arc rectifiers. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Witton, Birmingham. March 23, 1932, No. 8698. [Class 39 (i).] The temperature of the rectifier is regulated by means of repeatedly circulating fluid which is heated or cooled by means operated automatically. Fluid is circulated through a jacket 1, Fig. 1, by means of a pump 6. A temperature-responsive device 7 is connected hydraulically through a pipe 10 with mechanism 9 which is adapted to operate a valve 8 to regulate the amount of fluid passing through a cooler 3 and through a byepass pipe 4. A temperatureresponsive device 19 is adapted at a certain temperature to energize a coil 18 to operate a relay 17 which opens the circuit of a heater 11 fed from the bus-bars 12, 13. In a modification, de-energization of the heater 11 is effected through a time-delay device 20, Fig. 2, which is operated through a contact device 26 fixed to the load circuit breakers 27. The arrangement is such that the heaters are disconnected before the valve is operated. In a further modification, the load cannot be connected to the rectifier until the heater has been energized for a certain time. A time-delay device 42, Fig. 3, is adapted, at an interval after connection across the heater, to break the circuit through a coil 37 to close a relay 36 and thus to enable the operating coil 32 of the load circuit breaker to be energized by closing a button switch 34. The operation of the breaker may be made dependent upon the temperature of the fluid in the jacket. In another modification, valves 45, 47, Fig. 4, control the flow of fluid through the byepass 4 and the cooler 3 respectively. The valve 47 is controlled through mechanism 9 and a hydraulic connection 10 by a thermal responsive device 7. Contacts 48 associated with the valve 47 are adapted to be connected together when the valve is closed to energize a coil 50 which is adapted to close a relay 51 to energize a coil 46 and thus to open the valve 45. The thermal responsive means 19 on the tank is adapted at a predetermined temperature to de-energize the heater and the coil 46 of the valve 45. The byepass pipe 4 may include or be constituted by heat storage devices; it may be formed as a heating resistance which is lagged and connected to a U-shaped conducting strip which is connected to a core of the transformer.

Abstract: 690,090. Automatic control systems for hoists. METROPOLITAN-VICKERS ELECTRICALCO., Ltd. Sept. 19, 1950, No. 8963/52. Divided out of 690,035. Class 38 (iv). [Also in Group XXXVII] An asynchronous motor 1 which may drive a mine hoist is braked by applying directcurrent to its stator winding and connecting its rotor winding to a liquid rheostat 8, movement of a manually-controlled fluid-pressure servomotor 24, which varies the resistance, being automatically limited to prevent the rotor current exceeding the value corresponding to maximum braking torque. The resistor is adjusted by piston 25 moved by fluid supplied from pump 103. A control lever 100 passes a hollow sleeve 101 through the piston, an orifice 109 in the seeve being covered by the piston until the piston has moved to a position wherein the orifice is uncovered and the fluid by-passed to sump 103a. A valve 104 is linked to the piston so that the supply of fluid thereto, together with the rate of removal of rotor resistance, is reduced after the piston has accomplished a pre-determined portion of its movement. A normally-closed by-pass valve 111 is opened by a torque motor 112, which is energized in accordance with the output of current transformers 33, when the rotor current exceeds a value such that further reduction of the rotor resistance would cause a fall, instead of an increase of braking torque. The arrangement shown may replace the current-limiting arrangements described in Specification 690,035.

Title: Improvements in or relating to radio systems for guiding aircraft
IPC: G01S1/02
Filed: 1944-05-11
Abstract: 579,090. Radio approach path systems. STANDARD TELEPHONES & CABLES, Ltd., and WILLIAMS, H. P. May 11, 1944, No. 9033. [Class 40 (v)] In a receiver for use in aircraft approach systems of the kind in which overlapping beams of tone modulated waves are radiated so as to give inter-locking dot-dash signals, the said signals are applied through a discriminating circuit to a zero-centre indicator such as a cathode ray tube or a milliameter, the arrangement being such that failure of the transmitter or any part of the receiver right up to the last low frequency stage is immediately apparent in the indicator itself. The demodulated dot or dash signals are applied to a two-stage amplifier comprising valves V and V2 coupled together through a low pass filter which blocks tone ripple not already filtered out in the preceding demodulation stages. The dot and dash signals after amplification by V2 and after passing through a discriminating circuit DC produce a voltage across the resistance R2 which is applied between the plates Y1 and Y2 of the cathode ray oscillograph CRO. The ripple passes through a high pass filter and produces a ripple voltage across resistance R1 which is applied between the plates X and X2 of the CRO. Thus the ripple produces a horizontal trace which would fade to a point on failure of the transmitter or valve VI. Valve V2 is biassed by resistance R6 and the positive potential of the cathode is applied to the control grid G of the CRO, the cathode beam being suppressed unless normal cathode current is passed in V2. As signal amplitude increases the cathode current will increase and the brightness of the spot will increase. Where the indicator is of the milliameter type, a continuous and limited voltage of proper sign is obtained from the ripple voltage, added to the voltage obtained across R6 and applied to an additional bias winding. In this way the needle of the meter is brought to the centre zero when there is no output from the discriminator but may be arranged to move off the scale or behind a screen should either the ripple, or the cathode current of V2, or both, fail. Specification 579,072 is referred to.
