Title: Improvements in or relating to photographic printing forms for transferring written work and illustrations in offset, lithographic and book printing
IPC: G03F1/92
Filed: 1930-05-16
Abstract: 353,974. Photomechanical printing- surfaces ; photographic negatives. BERNET, U. DIEM-, Speicher, Switzerland. May 16, 1930, No. 15135. [Class 98 (ii).] A negative of an original design is produced for the purpose of photographic or photo-mechanical reproduction by mechanically printing, writing, or similarly applying the design on a transparent, grainless film of cellulosic material, such as viscose, which is rendered light-sensitive throughout its mass, exposing the film to daylight or artificial light passing through the applied design, removing the design from the film, and finishing the printed image by photo-chemical treatment. The negative so obtained may be intensified or toned without using special colours such as aniline. The method may be adopted at the time of printing a book or periodical to produce negatives for the future production of offset or lithographic printing surfaces of the work. The film may be sensitized as with ferric ammonio-citrate before or after applying the design to it, or it may be sensitized with silver chloride. The design may be removed either during or after the photo-chemical treatment, as by wadding moistened with benzine or benzol &c. The negative may be bathed in diluted glycerine before drying. Reference is made to a known method of producing a negative by applying written or printed matter to paper of sufficient transparency coated with a sensitive layer.

Title: Cop winding machine
IPC: B65H54/14
Filed: 1939-05-22
Abstract: 536,010. Winding thread. MASCHINENFABRIK SCHWEITER AKT.-GES. May 22, 1939 No. 15173. Convention date, May 23, 1938. [Class 120 (ii)] In a cop winding machine having a thread-guide carriage adapted to be propelled in a path parallel to the rotating cop and provided with lever means engaging a guide rod on a rocking shaft parallel to the winding spindle to oscillate the guide with respect to the carriage as it moves along such path, the carriage has a feeler which controls the movement of the propelling mechanism for the carriage. As shown, the bell-crank lever 33 carrying the feeler disc 34 is mounted on a pivot 32 in the thread guide carrier 25 which is guided by a rod 7 and supported by a shaft 14 which is rocked by a cam 6 through the intermediary of a crank 15 on the shaft. The shaft carries a stirrup 20 which is engaged by the bifurcated end of a crank 30 fixed to a pin 27 journaled in the carrier 25 and carrying the thread guide 29 which is oscillated above the bobbin 12 by the rocking of the shaft 14. The ends of the stirrup are adjustable in the shaft 14 so that the height of the stirrup may be adjusted to vary the traverse of the guide 29. The laterally directed arm of the lever 33 rests on the guide rod 35 carried by levers 37, 38 oscillatable about the rod 7, the lever 38 carrying an adjustable set screw 41 at one end and an adjustable counterweight 40 at the other. The set screw 41 supports an arm 43 which is reciprocated from an oscillating arm 50 and when the feeler disc 34 is moved laterally by the windings on the bobbin the set screw 41 moves down and allows a tooth on the arm 43 to engage and rotate a ratchet wheel 45 having a hub 47 around which is coiled a cable 53 connected to the carrier 25 and which is then fed forward to build the bobbin. The cable 53 passes over stationary rollers 54, 57 and carries a counterweight 58 which, at the completion of the winding and when a locking pawl is disengaged from the ratchet wheel 45, moves the carrier and thread guide to their original positions. The bobbin is supported between a driven head 2 and a counterhead 9 rotatable in a sleeve pressed forward by a spring in the bearing 8 ; a pin 13 is fixed in the sleeve and engages a slot in the bearing 8 to prevent rotation of the sleeve and to allow the counterhead 9 to be pulled back when a bobbin is to be released or inserted. The Specification as open to inspection under Sect. 91 comprises also the provision of a contoured rail for shaping the base and rear of the bobbin and of an adjustable set screw for varying the diameter of the wound bobbin. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of propeller blades
IPC: B21D53/78
Filed: 1937-06-01
Abstract: 496,577. Screw propellers. BLANCHARD, W. J. June 1, 1937, No. 15231. Convention date, June 10, 1936. [Class 114] [Also in Group XXII] Hollow blades for aircraft propellers are made by working a billet into root and blade portions and forging the blade portion to form leading and trailing edges defining an airfoil shape with a cavity therebetween by displacing metal from that part of the blade in which the cavity is formed. A round billet, preferably of alloy steel of the nickelmolybdenum type, is roughly shaped to the form shown in Fig. 3 by rolling forging, or the like in one or more steps. Figs. 4 and 8 show the sections along 4 ... 4 and 8 ... 8 respectively. The flow lines produced by this operation are lengthwise of the blade. The blank is then again heated and further shaped between forging dies 12, Fig. 18, to impart the desired pitch and produce the form shown in Fig. 11 having a central rib 20 and longitudinal cavities 16, 18. Another rib 22 is formed at the leading edge and rib 24 at the trailing edge. The outer faces 26, 28, 30 of the ribs, Fig. 14, define the outline of the back surface of the blade and merge into the shank at 35 and into a flat surface 34 at the tip. The bottoms of the cavities are preferably of straight section and the side walls of the cavities are preferably at right-angles to the bottom surfaces. The blank is then heat treated. The round part of the shank may be finished in a lathe and the shank then bored out to form a hollow part 48 with branches 50, 52, Fig. 21, leading to the cavities. The side and bottom surfaces of the cavities may be generated by planing, milling, or grinding. The surfaces 34, 35 and the faces 26, 28, 30, of the ribs are machined to receive the camber section forming the back of the blade. This section may be formed from a rolled sheet pressed in dies to the form B<1>, Fig. 24. The end of the forged section has a bevelled end surface 74, Fig. 33, shaped to receive the camber section which is secured to the forged section by fusion welding or, preferably, copper-hydrogen brazing, fillets being formed at 78, Fig. 34, during the brazing.

Title: Process for the manufacture of allo-para-oxocampnor
IPC: C07C45/29
Filed: 1931-05-28
Abstract: Allo-p-oxocamphor, a new isomer of p-oxocamphor, is manufactured by oxidizing p-oxycamphor either with 80-100 per cent of its weight of anhydrous chromic acid or in a weakly acidified condition with 70-90 per cent of sodium bichromate or the corresponding proportion of another bichromate, at a temperature below 60 DEG  C.  (If larger proportions of chromic acid or bichromate or higher temperatures are employed, p-oxocamphor or mixtures thereof with allo-p-oxocamphor are obtained).  In an example, p-oxycamphor, obtained from the compound of campherol and glucuronic acid by the process of Specification 375,018, is treated with sodium bichromate and sulphuric acid at 30-40 DEG  C., and the product extracted with ether and purified by dissolving in water, rendering the solution alkaline, adding a few drops of hydrogen peroxide to remove camphorquinone, extracting with ether and recrystallizing from 20 per cent alcohol, petroleum ether or pentane. p   The Specification as open to inspection under Sect. 91 (3) (a) comprises also the manufacture of p-oxocamphor.  In an example, p-oxycamphor is acidified with acetic or sulphuric acid and heated on a boiling water bath with more than the theoretical amount of sodium bichromate or anhydrous chromic acid.  The p-oxocamphor obtained is worked up by a method similar to that described above in the case of the isomer.  This subject-matter does not appear in the Specification as accepted.

Abstract: 606,347. Electric resonators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 20, 1945, No. 15793. Convention date, Aug. 7, 1941. [Class 40 (viii)] [Also in Group XL (a)] The output tank circuit of an inductive output discharge device comprises a cylinder 13 with truncated conical end closures 14, 15, forming a gap therebetween, and 'a magnetic lens is formed between a fixed annular member 17 and an axially movable cylindrical member 19, movement of the cylinder 19 serving to vary simultaneously the resonator gap to tune the resonator and the magnetic gap 16. The output circuit arrangements comprise a coupling loop 45 rotatable through 90 degrees by lever 45, a coaxial line 48, 51 one half wavelength long, and an output line 50 coupled thereto and terminating in a load such as an antenna (not shown). A movable plunger 49 engages the inner surface of the outer conductor 51 through resilient slitted ribbon 55 of sheet metal and the left-hand end of the inner conductor 48 and plug 56 form a variable condenser. Adjustment of the output circuit may be by changing the damping without altering the tuning. For this purpose control members 57, 62 are rotated together, the pitch of the internal thread on member 59 engaging the threaded right-hand end of inner conductor 48 being finer than the pitch of the internal thread of the member 57 engaging the threaded sleeve 58 so that the axial movement of the inner conductor 48 is less than the axial movement of the plunger 49; if however, the inside diameters of the members 56, 51 are equal the damping can be varied by rotation of member 57 alone. Alternatively, the tuning may be altered without changing the damping. For this purpose control member 62 alone is rotated so as to vary the length of the inner conductor 48 within the plug 56. The dimension of the resonator 12 measured from the centre of the envelope 2 to the arc of the sector shown in dotted lines at 14<1> is approximately one-quarter wavelength.

Abstract: 445,156. Discharge apparatus. ORV1N, L. J., 17, Kronprinsens Gate, Oslo, Norway. May 31, 1935, Nos. 15861 and 15862. Convention dates, May 31, 1934 and April 2, 1935. [Class 39 (i)] [See also Group XX] An electrical discharge chamber contains two electrodes 4 and 5 and is provided with a photo-electric layer 13 which is electrically connected to a grid 14 which controls the discharge between the electrodes. When an infra-red image is projected on the layer 13 it controls the discharge in the chamber through the grid 14 and a visible image is formed in a glow light or fluorescent layer in the chamber. The photo - sensitive area is divided into small areas as shown in Fig. 3 and each area is connected to a wire 9 which passes through the wall of the chamber and projects therein forming an element of the grid. The wires 9 pass through a layer 15 of poor conductivity which acts as a grid leak. Alternatively, a grid leak may be provided by coating the projecting ends of wires 9 with electron emitting substances. In the practical application shown in Fig. 12, a grating 71 is placed in the discharge chamber to prevent the spreading of ionization and to cause each discharge controlled by each grid element to keep to its own path. Between the electrodes may be arranged surfaces covered with substances emitting secondary electrons in order to intensify the image.
