Patent FI-982515-A (FI)
Inventor: AHOLA LASSE
IPC: B25B/
Filed: 1998-11-20
Abstract: The invention relates to a method and an arrangement 13 for detaching paper rolls, reeled up on paper cores and fixed to one another at their ends, from one another. The rollers are fastened to one another due to the fact that the edges of the narrower webs cut from a wider web overlap in the reeling stage following cutting. According to the invention detachment is performed by an elongate implement 13, which has two succeeding parts 14, 15, rotatable in relation to one another, and an eccentric shaft 16 forming a continuation of the one part 14, which constitutes the axis of rotation. For detaching, the implement 13 is inserted into the cores, following which the shaft 16 is turned so that the pressure with which parts 14, 15 of the implement act on the different rolls distances the rolls sideways from one another, so that the ends of the rolls come apart. The eccentric shaft 16 can be rotated by means of a hydraulic power source. <IMAGE>

Photographic silver images are treated by bleaching them to a silver salt image and then reducing this with thiourea dioxide or an alkyl derivative thereof at a pH greater than 7, whereby, according to conditions, the images are toned or the reflection density of the maximum black is increased. The silver image may be oxidized to silver bromide with an aqueous potassium bromide/ferricyanide solution or the silver salt image may be the ferrocyanide. The reducing solution preferably contains from “ per cent to 2¢ per cent by weight of thiourea dioxide and from 1 to 30 grammes per litre of alkali. To effect toning, the alkali is preferably sodium carbonate, but sodium or potassium hydroxide may be used in an amount of less than 15 g. per litre. The temperature of the reducing solution may be between 65 and 120‹F., and by varying this and the concentrations of the components a wide variety of tones can be produced. By using solutions containing at least 15 g. per litre of caustic alkali the reflection density of the maximum black obtainable on a photographic paper is increased.

Abstract: 1,108,252. Valves. SERVOTOMIC Ltd. 11 Jan., 1966 [13 Jan., 1965], No. 1204/66. Heading F2V. A gas valve comprises inlet 16 and outlet 17 separated by an internal wall 20 provided with a central aperture 21 whose upper edge forms a seat for a valve member 24 the stem 23 of which is at one end guided in a member 25 and at the other end attached to the upper side of a diaphragm 14 secured between housing parts 11 and 12. A spring 27 contained in a cup 28 threaded to part 12 of the housing loads the diaphragm and the cup may be rotated relative to the housing to vary the setting of the spring. A casing member 34 houses a sheet metal bellows 40, shown in the extended position, the closed lower end 42 of which is connected by a nylon-thread 44 and a spring 43 to the underside of the diaphragm to close the valve member. Liquid displaced from series connected vessels 47 and 51, when they are heated enters the space 54 between the casing member 34 and the bellows 40 so that the bellows are compressed and valve member 24 is lifted from its seat by spring 27. If only one of the vessels is heated the bellows is compressed an amount which causes the spring 43 only to loose its tension. The underside of diaphragm 14 is open to atmosphere through a hole 45 in the base of cup 28 and an aperture 46 in a casing member 32 so that the valve may act as a governor for the gas allowing the diaphragm to be depressed as the gas pressure increases thereby decreasing the effective area of aperture 50 and vice versa. The gas valve may be used in conjunction with only one of the vessels 47, 51 where the spring 43 is omitted. In the embodiment of Fig. 2 two concentric bellows are arranged on top of the housing part 11 and a plate connected to the upper ends of these bellows has a depending push rod 57 which contacts valve stem 23 after passing through guide 55. The valve is closed when the bellows are in equilibrium and liquid displaced from a vessel 67 when heated enters the annular space 61 between the bellows to lift push rod 57 and allow spring 27 to open aperture 21.

Title: Improvements relating to the manufacture of knitted fabrics
IPC: D04B9/38
Filed: 1953-01-21
Abstract: 744,670. Knitting-machines. NEBEL, M. Jan. 21, 1953 [April 24, 1952], No. 1759/53. Class 74 (2). In a method of knitting a fabric having held loops, alternate needles knit at one feeder and the loops between these needles are held on web-holding instruments and subsequently knitted by the intervening needles at a second feeder; the instruments, after having transferred the loops to the intervening needles and having been retracted from between the needles, are re-advanced with the most forward part of the instrument disposed at a higher level than the level at which the loops were transferred to the needles. If the web holder shown in Fig. 7 is used, the loops are drawn on a ledge Pa and are held in a throat Pb for penetration by the needles. The under edge of the rear end of each instrument is sloped, and on entry between the needles the instrument is tipped by a cam pressing on its rear end. The forward end is thus raised and rides over a loop which has been transferred to a needle and avoids pressing it into the latch joint. The web-holding instrument shown in Fig. 2 has a recess Pw on which a loop is drawn, and the tip Pv of the instrument is at a higher level than either its recess or throat; moreover the underside of the tip is slanted so that it is not necessary to tilt the instrument on entry between the needles. In both cases the instruments are disposed in tricks in a dial R inside the needle cylinder; long butt alternating with short butt instruments if each loop is to be drawn over only one instrument. In this event the instruments are provided with ledges Ps, higher than the ledges Pa, which keep the loops on the latches when the intervening needles are raised to clear their old loops beneath their latches. Each loop may, however, be drawn over a pair of instruments, in which case the instruments may be of the form shown in Fig. 15. In machines in which the web holders are disposed in tricks in a ring outside the needle cylinder, in place of a single instrument, instruments 15, 16 are provided in each trick. On entry between the needles each instrument 16 is tipped by a cam H3 so that the loop which has just been transferred to a needle is brought under a nose 16a. A new thread is laid on ledges 16a, 15u of the instruments, and the instrument 15 is retracted to sink a loop as the intermediate needles are lowered. Instrument 15 is then re-advanced and tilted downwardly by a cam H2 to the position shown in Fig. 20, so that the loop may be penetrated by the intervening needles. Instrument 16 is then retracted to bring the loop onto the nose 16a so as to keep it on the latch of a needle and also to bring it above a hook 15y of the instrument 15, both instruments being retracted out of the needle circle as the intervening needles descend. To draw longer loops the instruments may be held in their upwardly tipped condition while the loops are being drawn, and if the instrument shown in Fig. 15 is used, this must be done. Specifications 507,660 and 740,699 are referred to.
