Abstract: 1,024,726. Hay balers. GEBR WELGER. Aug. 27, 1963 [Aug. 30, 1962; July 12, 1963 (2)], No. 33884/63. Heading B5F. [Also in Division A2]  Bales of e.g. hay, which cohere without binding or tying, are produced by rolling the hay in a conical chamber W formed by circularly disposed rollers 2-6, of truncated cone shape as in Figs. 1 and 2, all of which are rotated in the same direction by a main shaft 9 acting through a gear 10 and co-operating gears 8. Material is fed from deck 1 into the chamber by retractable tines 7 mounted upon roller 2 and is rolled into a continuous cylindrical bale which is forced from the chamber into an axially aligned cylinder 11, rotated, in the same direction and speed as the continuous bale, by a pulley and belt 15, 14. The density of the issuing bale is controlled by adjustable leaf spring 20 which project into the interior of the cylinder. Spring biased members 23 are mounted upon a sleeve 24, which is reciprocated along the cylinder, by the pin 26, of lever 27, which co-operates with groove 25 of the sleeve, so that when the members are forwarded with the bale but at a greater speed the members bite into the continuous bale and tear off an individual bale which is then removed from the machine. In an alternative embodiment in Fig. 3 (not shown), the chamber comprises four rollers, one of which, 30, is driven directly by shaft 34, the others being driven through a gear 36 mounted upon a cylinder 37 having bale density controlling springs 39. The bale issuing from the cylinder passes through stationary cylinder 45 and abuts flaps 47, adjusted to yield under a certain pressure against the action of spring 50.

Abstract: 770,636. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. Nov. 24, 1954, No. 34023/54. Class 39(1). A rod of undulating shape for damping vibrations in grid structures of colour television tubes is made by placing a cut length of thermoplastic or vitreous material between members applying pressure in opposite directions at spaced positions, heating the rod to deform it and cooling and hardening the rod in its deformed shape. In the machine of Fig. 1, vitreous rod material is fed from a drum 23 over a chate 29 and felt rollers 27 to a rotatable cradle 31 and cut to length by a flame cutter 33. The cut portion slides down guides onto a lower grill 39 to which is pivoted at 43 an upper grill 41, each grill having taut strands of uniform or non- uniform spacing arranged over spacer bars. The strands of the upper and lower grills interleave and after clamping the rod between them, the machine moves a hinged heater element 61 into proximity with the grills and softens the rod. The grill 41 and the heater are then moved away and a blast of air from pipe 91 drives the rod down the guide arms 93 to a further cutter producing rods of the desired length. A motor 101 drives through appropriate gearing the feed drum 23 and cams 123, 151, 141, 131 which initiate the operations of cutting, moving the heater, opening and closing the grill and tipping the guide chate respectively. The base of the upper grill impact the plunger of a micro-switch 173 which controls the air blast from the pipes 91.

Abstract: 507,485. Colour photography. GASPAR, B. Dec. 9. 1937, No. 34079. [Class 98 (ii)] A multilayer light-sensitive material comprises support carrying a plurality of superimposed silver halide emulsion layers each differently sensitized and at least one of the layers containing a dye which is fast to ordinary photographic treatment solutions but can bo locally bleached in the presence of a silver image and absorbs the light rays for which the layer is predominantly sensitized, another layer being arranged behind this coloured layer and sensitive to these light rays so that a removable filter dye of substantially the same colour as the other dye is present in a layer in front of the second layer but not in front of the first layer. The concentration of the imageforming dyestuff is sufficient, for the colour intensity at the most intensely coloured parts of the image. The filter dye may he one that is destroyed by the photographic developers and is included in the first layer or in a separate layer of clear colloid between the two layers. In the example described, a paper support carries a blue-green emulsion sensitized to red light, a magenta dyed emulsion sensitized to green and a yellow dyed emulsion sensitive to blue. The top layer contains Xylenewalkgelb G in the form of its calcium salt, and in the same layer or in a separate gelatine layer as the yellow, dyestuff 4 : 4<1>-methenyl-bis-[1-(psulpho-phenyl)-3-methyl-pyrazolone-5]. The magenta layer contains Tuchechtbrillantrot 2B as its n-methyl-naphthoquinolinium salt and in the same or a separate layer either the sulphonic acid derived from methenyl-bis-oxythionaphthene or the red dyestuff obtained from 1-(psulpho - phenyl) - 3 - methyl - pyrazolone - 5 and #-anilino-acroleine-anile, The next layer is panchromatic and contains Pontamine Sky Blue 5BX. The material is exposed behind coloured or black and white positive part images and the image-forming dyestuffs locally destroyed by an acid thiocarbamide solution or 5 per cent hydrobromic acid, the other dyestuffs having been destroyed in the development.
