Title: Method of producing printing blocks with correct colour values for multi-colour printing
IPC: G03F3/04
Filed: 1931-08-26
Abstract: 384,364. Photo-mechanical printing. FOTSCHKI, B., 64, Schlesische Strasse, Dusseldorf, Germany. Aug. 26, 1931, No. 24036. [Class 98 (ii).] To obtain colour printing blocks for multicolour printing, coloured screen-diapositives (e.g. pigment images) are made and each component diapositive is individually retouched whilst superimposed on the other components to give a visual complete colour image, the different blocks being then made from the retouched diapositives. The retouching may be by known methods which are described and include (1) hand retouching with an ordinary hand or line chisel : (2) local application of a colour-destroying chemical : (3) surface application of a localized protecting layer and etching to decrease the size of the dots without effecting their colour saturation : (4) local application of colour as by means of an aerograph or other spraying means : (5) application of chalk or other pigments to widen the screen dots without affecting the colour saturation thereof. To make the printing plates direct from the diapositives the coloured layers of the diapositives may be blackened with suitable pigment. Alternatively each screen-diapositive may be converted into a printing negative by colouring the base black between the screen points, using the colour picture as a resist. The colour of the original image may in addition be eliminated.

Title: Photoconductographic processes
Inventor: WILLIAMS CARL JAMES
IPC: G03G5/026
Filed: 1963-06-18
Abstract: 1,098,301. Electro-photographic processes. KODAK Ltd. June 25, 1964 [June 18, 1963], No. 24170/63. Addition to 942, 034. Heading G2H. A method of producing an image of silver or a water-insoluble silver compound comprises exposing a photo-conductive layer to visible light imagewise, passing a current through the layer and a water-permeable layer in contact with it and containing moisture, an electrolyte, and a developing compound, the developing compound reacting in an alkaline medium with a silver salt to form the image substance, the alkaline imagewise region necessary to form the developed image being due to the imagewise production of hydroxyl ions by electrolysis. The photo-conductive layer may be zinc oxide dispersed in a hydrophobic binder. The silver salt to be developed may be introduced into the water-permeable layer before or after the production therein of the alkaline image. The layer may be gelatinous and carried on paper. For use with a silver halide the developer may be 4-methoxynaphthol dissolved in di-n-butyl pthalate and dispersed in aqueous gelatine. For repeat printing, the photo-conductive layer is on one support and is contacted by the water-permeable layer on a separate support while current is passed. An e.m.f. at 60 volts is used; the water-permeable layer containing developer is then removed and swabbed with silver nitrate solution to produce a silver image. Alternatively, the above gelatinous coating is applied on a silver chlorobromide emulsion layer on a baryta coated paper support. After electrolysis the directly produced silver image is fixed with hypo solution.

Abstract: 421,493. Liquid - fuel burners. SQUIRE, T. R., 53, Victoria Avenue, Whitley Bay, Northumberland. Sept. 5, 1933, No. 24611. [Class 75 (i)] The tapered base 3, Fig. 1, of an oil fuel burner is held in the burner socket 1 when the oil cock 8 is open by a segment 9<a> on the cock handle 9 engaging a hollow plunger 5 slidable against the resistance of a spring 6 in the base 3. When the oil cock is closed the oil burner and its base may be withdrawn, and a pawl 10 carried by a spring 11 then engages a bent extension 9b of the handle 9 so as to prevent the cock from being opened until the burner base is replaced. A needle valve regulating the fuel discharge aperture of the burner may be arranged to be operated by the rotation of the plunger 5. Fig. 5 shows another construction in which the burner base may be held in contact with a nipple 18 in the burner socket 16 by a shouldered pin 22 mounted between springs 23, 24 in a locking bolt 20. In the Figure the burner base is removed and the bolt 20 has been raised by the springs into contact with a retaining plate 21. The oil cock cannot now be opened owing to the engagement of the cock handle with the bolt 20. When the burner base is inserted in the socket 16 the locking bolt 20 is depressed by hand to allow the handle to be moved over it. A segment 26<a> on the handle then retains the burner base in position until the cock is again closed.

Class 107 A road surfacing machine having a compartment for receiving the surfacing material e.g. asphalt, and a discharge opening for delivering the material to the road is characterized in that the compartment contains a delivery shoot which can be tilted to feed the material towards the opening. In the machine shown, delivery shoot 17 may be tilted by means of the pivot adjacent the front edge 17c of its bottom wall 17a so that material is fed towards distributing box 11 and discharge opening 12. Tilting is effected by wire ropes 18 attached to winding drum 20, or by hydraulic rams. Power-driven roller 13 compresses and smoothes the material dropping through opening 12 on to the road. The machine also comprises ramps 22, which normally slope downwardly in contact with the road and are attached to roller 21, and platform 25 which is pivoted about its forward edge 25a and rests at its other end on cam hump 26 of roller 21, so that as the back wheels of a loaded tipping lorry 23 move from ramps 22 on to platform 25 the load there exerted lifts the ramps 22 clear of the ground; the machine can thus move forward carrying the lorry 23 by its back wheels . In a modification, leaf springs assist in lifting the ramp off the road. Specification 719,758 is referred to.

Abstract: 1477384 Roll balers CHROMALLOY AMERICAN CORP 4 June 1974 [2 Aug 1973] 24749/74 Heading A1F A baling apparatus comprises a wheeled frame 25 under which hay is gathered and rolled into a swath and a twine feeding unit 41 from which twine is fed, cut to length and wrapped around the swath. The leading end of the twine is fed to the swath by a feed roller 62, Fig. 4, as the swath is being formed and the twine is covered by further hay during swath rolling. so that the ends of the twine do not need tying. The feed roller supplies three parallel twines (T 1 ), (T 2 ), (T 3 ), Fig. 2, (not shown), from a supply 52 with three coils. The swath is rolled by a set of baling chains 31, Fig. 1, with tines 33. The. lower run of the chains rolls the hay along the ground into a swath. The sprockets 28 of the baling chains are mounted on lever -arms 27 to allow arching of the lower run of the chains as the swath' grows. The drive of the feed roller 62 is effected by a pivoted arm 92 operated by an operator pulling a lanyard 94 to move a clutch roller 91 into engagement with a slipping belt 79 on a driven pulley 78. The feed roller 62 has a roughened surface 63 where it engages the twines. The twines are severed by fixed blades 107-109, Fig 5, co-operating with movable blades 113-115. The movable blades are mounted on a plate 110 which is spring- urged against a stop 118 which is moved to allow blade movement by engagement of a lug (125), Fig. 3 (not shown), on a chain (124) with a crank arm 122. The blade carying plate 110 is returned against the spring- bias by a bell-crank 134, Fig. 5, connected by a rod 136 to the gate 22, Fig. 1, at the rear of the baler.
