Title: Improvements relating to a method of producing a photolithographic printing material

Abstract: 547.795. Photo-lithographic printing plates. PRINTING & ALLIED TRADES RESEARCH ASSOCIATION, MACDOUGALL, G., KODAK, Ltd., GRESHAM, D. C., and SELMAN, R. F. W. Jan 1, 1941, No. 36. [Class 98 (ii)] A method of producing a photo-lithographic printing surface on a support having a grained or roughened surface coated with a silver halide emulsion, of the kind in which a latent image is first produced and developed in the coating, the emulsion colloid is hardened imagewise either during or after development, and the unhardened colloid is then removed, includes also the further steps of forming, preferably after drying the plate, a hydrophobic ink-accepting film on the areas of the support from which colloid has been removed, and then removing the hardened colloid with a hydrochlorite. The support may be a rigid or flexible zinc or aluminium plate, grained or roughened so as to be capable of holding water, and bearing a thin layer as of silver to prevent its fogging the emulsion. The exposure may be made in a camera, or by contact or projection printing from a positive. The plate may be developed in a tanning developer, treated with hot water to remove the unhardened colloid, and dried. After removing the protective coating wholly or partially from the bared parts of the support by treatment as with a solution of nitric acid in ethyl alcohol, the plate is treated with a solution of ferric stearate in benzene which deposits a hydrophobic film strongly adherent to the areas of clean metal, dried, immersed in cold water to swell the colloid, swabbed to remove surplus water, treated with lithographic developing ink, dried again, treated with a solution of sodium hypochlorite to remove the tanned colloid, washed, and gummed up in the usual way to protect the non-image areas. As the ferric stearate is not sufficiently ink-receptive, it is removed together with the developing ink by means of benzene, and the plate is made ready for printing by rubbing up with the usual bitumen solution, rolling up with press ink and gum-etching. Specification 545,942 is referred to.

A high-pressure electric discharge lamp is formed by at least two bulbs connected by a narrow tube supporting and fitting closely round a rod of refractory metal, the ends of which project one into each bulb to form one of two discharge electrodes in each bulb. In Fig. 1 the envelope of a D.C.-operated xenon- filled high-pressure electric discharge lamp consists of three approximately spheroidal quartz bulbs 1, 2, 3 connected along their longer diameters by quartz tubes 4, 5 which are collapsed on to tungsten rods 6, 7 tapered at one end to form cathodes 8, 9 and having cylindrical tungsten blocks 10, 11 mounted, with their axes at right-angles to the axes of the rods, at the other end to form anodes. Lead-in seals 18, 19 close stems 14, 17 which are collapsed on to tungsten rods 13, 16 forming and supporting the end cathode and anode respectively. In a two-bulb lamp, Fig. 2 (not shown), the interconnecting quartz tube is collapsed on to a tungsten rod wrapped with molybdenum foil and having a keying indentation for the collapsed quartz. The cathodes are tipped with thoriated tungsten as in Specification 677,551. Dimensions and operating conditions are specified for this arrangement. Different gas or vapour fillings are referred to for the case in which the interconnecting tube is effectively closed by the rod within it. Application of the lamps to projection and flood-lighting, rotation of the lamp about a horizontal axis and magnetic deflection to prevent bowing under convection are referred to.

Title: Directly reading type soil conductivity measuring apparatus
Inventor: NAGATA KIYOSHI
IPC: G01N33/24
Filed: 1987-01-05
Abstract: PURPOSE:To perform a measurement preventing polarization due to electrolysis, by a method wherein DC current flows through a measuring instrument and current equivalent to the amount of electric charges through the instrument runs alternately through soil as AC switching the direction of energization by equal amount. CONSTITUTION:This apparatus is provided with conductivity measuring electrodes P1 and P2, a DC mobile coil type instrument M indicating conductivity and a non-stable multivibrator circuit MB. Resistance elements of a collector circuit of transistors (TR)a and (TR)b composing the circuit MB are replaced with relays La and Lb and operated alternately by an equal time limit. Exciting contacts a1 and a2 and b1 and b2 of the relays La and Lb are made to cross each other to be connected by insertion between the electrodes P1 and P2 and the instrument M. Thus, DC flows through the instrument M and runs between the electrodes P1 and P2 as AC to prevent polarization due to electrolysis in soil, thereby enabling direct reading of the conductivity of the soil with the instrument M.

Title: Improvements in or relating to video tape recording
IPC: G11B27/029
Filed: 1967-01-03
Abstract: 1,123,962. Editing recorded video tape. AMPEX CORP. 3 Jan., 1967 [3 Jan., 1966], No. 347/67. Heading G5R. A method of recording a new video signal on a magnetic tape which already bears a video signal in tracks disposed obliquely with respect to the tape comprises recording the new signal in tracks each of which is directly over a track of the previous signal to effect a high degree of erasure of the previous signal. Preferably the method is used with a helical scan video tape recorder; the capstan and head-drum servos are in the playback mode so as to be synchronized with the control track of the previous recording whereas the signalrecording parts are energized in accordance with the new video signal. The tape may be edited, by the superimposition method identified above, to include a "short insert" or a "long insert" of new matter. A "short insert" is one extending over a length of tape less than that lying between an erase head (located perpendicularly across the whole video region of the tape) and the recording head, and in this case the recording head is energized for the insertion but the erase head is not. For a "long insert" the erase head is energized at the same time as the recording head at the beginning of the operation. Fig. 2 shows the beginning, on the tape, of such an insert Tape 11, moving in direction 13, bears previously-recorded video tracks 12 and control track 14. The erase head (not shown), is located upstream of the recording head by a tape distance X-Y. When the recording head was at point X, new material was superimposed on the previous material, producing tracks shown as dots. The erase head was then at point Y, so that the video tracks to the left of the vertical line shown adjacent to Y were erased. The recording head 16 is now at point Y, and the portions of track to the left of the vertical line are of new material, represented by crosses, recorded on erased tape. The first full-length track of new material is about to be recorded in one of the erased tracks by head 16 moving in direction 17. Where the tape is read back to produce rectangular images, a rectangular "window" of new information may be inserted in the image by the method of the invention. Preferably the window has dimensions each equal to one third of those of the surrounding image, and occupies the central part of it. The appropriate editing takes the form of energizing the recording head with the new video information only during the middle third of its transit along those tracks which themselves produce, on playback, the central third of the whole rectangular image.
