Abstract: 773,247. Method and device for photographic development and for image transfer. RUIJS, F. W. March 1. 1955 [March 5, 1954], No. 6059/55. Class 98(2) A sensitized carrier as of paper or this together with a carrier for the transfer process is introduced as through guides into an appropriate processing liquid and projected until the advancing edge or edges contact a supporting and carrying means in the liquid, and such means are then both moved by and guide the edge or edges upward until the latter are caught by co-acting rollers for pressure to remove excess liquid or to effect image transfer. As shown introduction is made between the several guides 2, 3, 4, 5 in container 1 until abutments 9 of projections 8 on a connecting strip 7 between a pair of pivoted arms 6 are reached, and further introduction causes the arms 6 to swing anticlockwise and carry the edge or edges upwards until the abutments 9 pass through recesses 10 of a ridgidly fixed releasing means 11 to lift the edge or edges from the features 8, 7 and allow them to be received by rollers 12. 13. The arms 6 may be counter-weighted at 14. The tank 1 has a low portion 15 to receive any precipitate from the liquid. In Fig. 5 (not shown), the supporting and carrying means are constituted by a carriage slidable up a curved guideway. Fig. 4 and 6 (not shown) are directed to variations concerning the pivot arms 6 and the releasing means 11 respectively. The device avoids resistance and possible sticking of the carriers which may result from the use of curved guides.

Title: Method and means for the selective handling of rolled billets
IPC: B21B43/00
Filed: 1944-04-04
Abstract: 600,561. Rolling; conveyers. LOEWY ENGINEERING CO., Ltd.. and LANGEN, M. April 4, 1944, No. 6281. [Class 83 (iv)] [Also in Group XXV] In rolling billets from ingots, particularly in continuous rolling mills where the rolled product is cut by flying shears into lengths that are forwarded to a cooling bed by a roller table, the lower grade billets that are produced from the top portion of the ingot are separated from the remainder of the batch. Billets cut by the flying shear 10 pass by a roller way to a roller table having skew rollers 12 that form the billets into a close pack, against side rollers 14, restrained by a stop 24. On removal of the stop the batch passes to a cooling bed approach table 17 or 18 according to the stop 124 in operation in connection with the live rollers 16. Fingers 25, Figs. 2 and 4, are carried by arms 26 on shafts 27 rocked by levers 29 linked at 30 to the rod 31 of a hydraulic &c. cylinder 33 mounted to oscillate in a bracket 34. The arms 26 can be slid along the shafts 27 so that the fingers select and lift the required number of billets by arms 38 controlled by worm and bevel gearing 39, 44 from a hand wheel 42. The billets remaining on the rollers 16 are traversed laterally on to the cooling-bed by dogs upstanding from chains 20 driven by motors 22. The selected billets are then lowered again on to the rollers 16 and are forwarded for transfer by a lateral pusher 46 to a collecting station 47 either for cooling or for transfer for further treatment. In a modification, the fingers 25 are dispensed with and the stops 124 are adjustable laterally to allow the selected number of billets to pass directly to a station such as 47, and in a further modification the stops have a stepped or inclined edge and the raised position is adjustable to permit the selected number of billets to pass.

Title: Conveyor with driven slippable rollers
IPC: B65G47/26
Filed: 1975-02-17
Abstract: 1495164 Rollerway conveyers SHUTTLEWORTH Inc 17 Feb 1975 6546/75 Heading B8A Rollerway rollers 50 and 51 (Fig. 2) each have a concentric bore which is slightly larger in diameter than a drive-rod disposed within the bore. This allows the roller to slip under excess load relative to the drive rod. Also until slip occurs, the driving torque applied to the roller increases with the gravitational load on the latter. In Figs. 2 and 3, rollers of a rollerway section 33B rotate at a slower speed than those of an upstream section 33A. The rollers of both sections are driven from a single motor 67 through the belt gearing shown. In Fig. 5, a section 35 of rollers driven by belt gearing similar to that described above, is movable from the full line position, to the broken-line position, and vice versa, relative to the fixed main section 33B (Fig. 2). The drive shaft 86 for the belts 85 driving the individual rollers, is in keyed coaxial sliding relationship with the drive shaft 68 of the belts of the section 33B. Rollers in the vicinity of the bearing (Fig. 8, not shown), are driven by couplings to adjacent rollers, instead of from belts directly coupled to the shaft 86. A frame 45 (Fig. 3) may support lane-dividing members, adjustment of the spacing of which, may be effected by screws 44 (Fig. 2). A rollerway corner section is described (Fig. 9, not shown). Roller drive rods may be supported by plastics side members 200 (Fig. 17), each rod (not shown) resting in a recess 201 of slightly more than 180 degrees of arc. Slots 202 may provide for thermal expansion. Rollers may be built up from unit rollers 210 (Figs. 19 and 20) having recesses 215 formed to provide cooling ribs 211 and 215. The rollers may be of rubber or plastics and may have outer surfaces of higher or lower friction coefficient, compared with the coefficient of the surface of the inside bore. The outer surface may be of stainless steel. The rollers may be of diabolo shape (Fig. 15, not shown). There may be a roller section of reduced diameter between two normal-diameter sections (Fig. 16, not shown).

[Classes 72 and 82 (i)] The ductility and toughness of non-austenitic iron alloy castings containing not more than 10 per cent of nickel, chromium, and manganese together are improved by reheating the castings after they have been removed from the mould to 1100-1350‹ C. and preferably 1200-1350‹ C. The alloys may contain up to 2 per cent of manganese, up to 6 of nickel and up to 6 of chromium and also up to 1.0 of carbon, up to 2 of silicon, up to 4 molybdenum, up to 3 of vanadium, and up to 4 of tungsten, the upper limit of these additional elements being 10 per cent.

[Class 4.] For cooling aircraft motors and for removing the boundary layer of air from the upper surface of the wings, a blower draws air through orifices in the surface and discharges it through a radiator or radiators which may be arranged in the wing. A blower d driven from the engine b draws air from a chamber f communicating with pipes h having branches i leading to orifices k in the upper surface of the wing. The air is discharged through a radiator e and through openings l in the fuselage just beneath the wing. Modifications are described in which both the blower and the radiator are arranged within the wing, the blower in one case being driven round by peripheral blades acted upon by jets of exhaust gases. In another case two blowers on a common transverse axis aspirate air through two radiators from the interior of the wing which has holes in its upper rear surface and the air is discharged through two orifices in the lower surface.
