Title: Structure for use in fabricating railway bogies
IPC: B61F5/52
Filed: 1975-09-10
Abstract: 1521096 Railway vehicle undercarriages DEMAG AG 10 Sept 1975 [14 Sept 1974] 37264/75 Heading B7L A basic framework structure 2, H-shaped in plan, for fabricating railway vehicle bogies comprises a pair of spaced apart side frames 3 each of which has two longitudinally spaced apertures 6 mounting axle bearings 7 of axles 9 extending between the side frames and carrying wheels 10, the frame 3 being interconnected by welding to an I-section cross-beam 5, 5a, centrally between the axles 9, the beam having its centre of gravity disposed in a plane containing the axes of the axles 9 in their mean positions and the beam also having its vertical web 5 surmounted by a horizontal flange 5a. The ends 5c of the web 5 are extended so as to project laterally beyond and above the flange 5a and penetrate vertical slots in the frames 3, wherein they are welded. By welding a box-shaped frame 11 on the upper surface 5b of the flange 5a and mounting a spherical bearing part 12a on the support surface 11b of the frame 11, the structure forms a two-axled bogie with the bearing part 12a engageable with a spherical bearing 12 on a vehicle body underframe 13. In this instance the axle bearings 7 are supported by leafsprings 8 mounted in shackles on the side frames 3 but they may be supported by helical springs as described with reference to Fig. 3 (not shown). The box frame 11 mounts rollers 14 on horizontal axes for engaging the undersurface of the underframe 13. Two such bogie structures may be used to form of four-axled bogie Fig. 5. In this case bearings 19 mounted directly on the cross-beams 5 engage bearings on the ends of a connecting girder 15. The latter carries a central bearing 12 for connecting with a vehicle body underframe 13. A three-axled bogie may be fabricated by combining the basic structure of Fig. 1 with a second structure for a single axle, the second structure being pivotally connected the cross-beam 5, 5a of the basic structure by a a girder extending between the side frames of the basic structure as described with reference to Figs. 7 and 8 (not shown). Multiple axle bogies having more than four axles may be made-up by utilizing basic and secondary structures as described with reference to Fig. 9 (not shown).

Title: Improvements in animal drenching devices
IPC: A61D7/00
Filed: 1962-10-05
Abstract: In an animal drenching syringe the dosage is determined by limiting the length of stroke by means of a projection, fixed in relation to the plunger, engaging in one of a series of longitudinal grooves in the wall of the barrel.  A hollow, tubular handle 4, Fig. 3, (not shown) encloses a fixed plunger 22, Fig. 2, (not shown) mounted on a threaded tube 24 which is screwed through an end plate 25 held in the handle by the inturned ends of a spring clip 26.  The cylinder 9 fits over this plunger and is normally urged outward by a spring 11.  It carries a discharge nozzle 18, enclosing an outlet valve 34 while an inlet valve 32 on the piston sealing member 31 seals the bore of the tube 24 so that an outward stroke of the cylinder 9 causes it to be refilled through a tube leading from a supply through a union 28. The outer part of the cylinder has a thickened wall and carries a ring 13, which may be freely rotated around it so that a recess 14 in the ring may be aligned with any one of a number of slots 21, of differing lengths, in the wall of the tube.  A screw 7 engages in the operative slot and thus limits the travel of the cylinder relative to the plunger and, in order to change from one slot to another, the cylinder is pressed fully inward, so that the screw is located in the recess 14 and the cylinder is then rotated until the desired slot 21 is aligned with the screw whereupon release of the cylinder causes the screw to pass into the slot concerned.

In a photographic colour transfer process giving a positive colour image and comprising exposing a photo-sensitive silver halide element containing in the emulsion layer or in an adjacent layer a non-diffusible colour coupler which becomes diffusible at a high pH, developing with a liquid processing solution in the presence of a colour developer at a pH below said high pH to form an immobile dye at exposed areas, treating with an alkaline solution of pH at or above said high pH to solubilize the colour coupler in the unexposed areas and contacting the element with an imagereceiving layer to allow imagewise diffusion of the colour coupler, the treatment with the alkaline solution at or above the high pH is conducted in the presence of a development restraining substance. The colour coupler may be coloured and itself, form the colour image or it may be colourless in which case the image-receiving layer containing diffused coupler is treated with a colour developer under oxidizing conditions, e.g. in the presence of an oxidizing agent or electrolytic oxidation. The development restrainer substance may be an anti-foggant compound such as benzotriazole, 5-nitro-, 5-methyl- or 2-amino-benzimidazole, 1-phenyl-5-mercaptotetrazole, 2-mercaptobenzothiazole, thioacetanilide or mixtures thereof, and may be present in the high pH alkaline solution, in the image-receiving element or in a layer of the photo-sensitive element separate from the emulsion layers or layers containing couplers. The restrainer may become diffusible only at the high pH used for the transfer step, e.g. it may contain groups, such as phenolic hydroxyl, sulphonamide or substituted sulphonamide, such that it is ionized only at high pH, or it may contain groups hydrolyzed only at high pH, e.g. long chain esters of oxalic acid. The colour coupler may be diffusible only at high pH by virtue of a hydrolysable long chain anchoring group e.g. an ester of oxalic acid or by incorporation in a water immisible mat material which is slowly permeable by alkali or by incorporation in a slowly hydrolysable material. The developing agent may be incorporated in the liquid processing solution, in the emulsion layer or in the image-receiving element.
