Patent GB-563503-A (GB)
Title: Improvements in sensitive photographic materials
IPC: G03C1/85
Filed: 1943-02-12
Abstract: 563,503. Photographic film and paper. KODAK, Ltd. Feb. 12, 1943, No. 2373. Convention date, Feb. 12, 1942. [Class 98 (ii)] The tendency for formation of static when coating a light-sensitive layer on a length of flexible support is reduced by placing an electrically-conducting border along one or each margin only of one or both sides of the support, and coating the light-sensitive layer between the margins. The outer edge of the border may coincide with the edge of the support ; its inner edge may lie short of, in contact with, or slightly beneath the edge of the sensitive layer. A second light-sensitive layer may be coated on the rear of the support with or without placing one or more conducting borders on said rear. In coating wide rolls which are to be severed into rolls of standard widths, conducting strips may be coated not only along the margins of the roll so as to lie at their inner edges beneath the emulsion edges, but also along the lines of severance so as to afford protection from static when exposing the finished rolls. The border may be applied by coating continuously or discontinuously a dispersion of carbon in gelatin, cellulose nitrate or a cellulose ester or ether, prepared as described in Specification 544,006. The material may be supported at its margins during coating and drying. Fig. 1 shows an apparatus in which film base dope 10 is coated from a hopper 11 on to a drum 12, the set film being stripped off at 14 and passed through baths 15, 16 for applying a substratum on one or both sides. Conducting borders 26 are then applied from hoppers 25, whereafter it is dried, reeled and transferred to a machihe in which it is passed through a bath which applies an emulsion coating between, and preferably slightly overlapping the borders, dried, and again reeled. Passage through a third machine slits the roll into films of desired width and trims away the conducting borders. In a modification, emulsion is applied to one .side of the roll from a hopper and to the other by dip coating, and the cutting machine not only slits the roll, but also severs the slit films into rectangular pieces. In a further modification, additional hoppers between the hoppers 25 apply conducting strips along the lines where the roll is to be subsequently slit, and in the cutting machine the slitting and trimming cutters are so disposed that the severed films each have a conducting border along each margin.

Abstract: 970,816. Multiplex radio signalling. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Jan. 25, 1962 [Jan. 25, 1961], No. 2843/62. Heading H4L. A switching circuit for a plurality of V.H.F. radio channels comprises a parametric amplifier associated with each channel, a common output circuit for the V.H.F. signals and means associated with each of said amplifiers for causing the channels to be switched automatically in sequence to the common output circuit. As shown in Fig. 1, V.H.F. channels I, II, N are supplied to one arm of respective circulators 2 whose other arms are connected respectively to a matching load 3, output lead 4 and parametric amplifier 5. Each of the amplifiers 5 is controlled by a pump klystron 6, the klystrons being energized in succession for the duration of a gating pulse from a generator 8, the pulses appearing on respective leads 7 in succeeding time intervals in the desired order. The circulators 2 pass the input signal 1 into the corresponding parametric amplifier 5 which passes an amplified signal via the output lead 4 to the common output circuit 9 when the associated pump klystron is energized. In a further arrangement, Fig. 2, each V.H.F. input 11 is connected to a parametric amplifier 12 of the " up-converter " type, the amplifiers 12 being controlled by a single klystron 13 supplying the pumping frequency continuously and connected to a matching load 14 and via lead 15 to the common output circuit 17. Gating pulses from a source 20 are supplied to waveguide switches 18, 19 of the ionizable gas type so that when one is shorting the other is open. The waveguide switch 19 is tuned to the sum of the input and pump frequencies and the switch 18 is tuned to the difference frequency. The pulses from the source 2 ensure that for a time t 0  to t 1  channel I is switched to the output circuit 16 and for a time t 1  to t 2  channel I is switched to the load 14, channel N being switched in sequence in a similar manner.

Abstract: 308,029. Thomson, G. M. Jan. 31, 1928. Fire - extinguishing by foam. - A dense uniform foam, adapted for the manufacture of cellular building material, is made by bubbling air through an aqueous solution of a bubble forming agent and subdividing the bubbles rising above the surface of the liquid, which surface is maintained at a constant level. In the apparatus shown, the bubble forming liquid is admitted by the pipe 4 to the space above a perforated plate 2 and is maintained at a constant level. Air at constant pressure is admitted by a pipe 5 to the space below the plate 2, so that it passes up through the perofrations and forms a froth above the surface of the liquid. The bubbles of this froth are divided by two sets of vertical blades 11, 12, rotating in opposite directions, so that a dense foam is formed which is delivered from the spout 3. The blades are stream-lined in cross-section. Specification 200,855 is referred to.

A fluid check is shown, the cylinder 4 being formed integrally with the shoe and the piston being connected to a disc crank 8 which has a suitable bearing in the shoe; the crank is prevented from rotating by an arm 9 fixed to it and to the floor and passing through a partcircular slot in the base of the shoe. The door is shown mounted on the pivot pin 11 of a floor spring mechanism, by a boss 10 non- rotatably engaging the pin and having a bearing in the shoe ; the boss 10 has an arm 2 engaging with a screw 3 in the shoe to allow adjustment of the closed position of the door but otherwise preventing relative movement of door and boss.

Abstract: 637,101. Counting-apparatus. CRABTREE & SONS, Ltd., R. W., and BURLS, J. A. E. Feb. 4, 1947, No. 3298. [Class 106 (i)] Apparatus for regulating an interval comprises a series of components moved successively to a control position and each capable of being set in operative or inoperative setting, and a presetting device operated by a component in operative setting to set a succeeding component in operative setting, the device being adjustable to vary the spacing between such components to regulate the interval. A shaft 1, Fig. 1, rotates once during each stitching cycle and drives through worm gearing a disc 7 carrying pins 9 round its periphery so that one pin 9 registers with a projection 20 each cycle. Each pin 9 may project from the right or left of the disc 7 and is retained in either position by a spring 10 co-operating with an appropriate groove. Initially a number of consecutive pins 9 project to the right according to the number of signatures required to a "count," while the next pin 9 projects to the left. Upon the first rotation of the shaft 1, a cam 15 causes a shaft 11 to rock clockwise, in which position it is retained throughout a succession of cycles by the pins 9 which project to the right and co-operate with the projection 20 which is carried by an arm fixed to the shaft 11. While the shaft 11 is held in this position it holds a stop plate 37, Fig. 7, out of the path of a stop 34 on an arm 28, Fig. 6, pivoted at 29, so that a cam 32, rotated once each cycle, reciprocates the arm 28 and through an arm 27 feeds a signature to the stitching-machine. When the pin 9 which projects to the left registers with the projection 20, the shaft 11 is free to rock back under the tension of the spring 17 and in so doing it moves the stop plate 37 into the path of the stop 34 to inhibit the signature feed, so that in the absence of a signature a locking stitch is formed and, through an arm 19, rocks a setting lever 22, pivoted at 23 on an arm of a setting disc 25, to set a following pin 9 to project to the left. The disc 25 is preset so that the lever 22 registers with the pin 9 appropriate to the required " count," the sixteenth for a count of fifteen, the intervening fifteen pins 9 remaining to the right as set by a wedge 21 after passing the projection 20. Specifications 610,290, 624,785 and 637,102, [all in Group XVI],.are referred to.
