Filed: 1975-02-05
Abstract: 1444883 Doffing and donning mechanism HEBERLEIN & CO AG 5 Feb 1975 [6 Feb 1974] 4880/75 Heading D1J When the package 3 is fully wound a travelling bobbin changing mechanism 9 running on rails 8 stops at the winding station. The mechanism 9 carries two sets of cradles. The first set 12 swings from the setting shown in Fig. 1 to that shown in Fig. 2 to hold the axis of the wound package 3 between arms 24, 24'. At the same time the second set of cradle arms 13 also swings to the setting shown in Fig. 2, each arm 13 carrying a further arm 13' that holds the empty bobbin 18 and swings it to a setting beyond the periphery of the wound package 3. Each arm 13 also carries a pneumatic device 20 that in Fig. 2 is aligned with the cradle arms 2 that normally hold the package whilst it is being wound. The pneumatic device 20 causes the cradle arms 2 to move apart such that the wound package is now fully supported by the cradle 12. Fig. 4 shows how the cradle 12 then swings downwardly to doff the wound package onto a ramp 22 whilst the cradle arms 13 move the empty bobbin 18 into alignment with cradle arms 2. The pneumatic device 20 is then used to close the cradle arms 2 onto the ends of the empty bobbin 18 and a fresh winding cycle commences, the cradle arms 13 being then swung back to a setting as in Fig. 1. A further arm 15 carries a driven roller 16 that engages the wound package 3 during the whole of the doffing operation to rotate the package. The further arms 13' are stated to carry thread-guides 30, 30' outside the operating range of the reciprocating thread-guide 6 to move the thread to the side of the bobbin where a filament reserve will be collected. The winding apparatus may have a device 21 which, when the package 3 is fully wound, emits an impulse to cause a pneumatically actuated arresting bolt 30a to stop the travelling mechanism 9.

Title: Luminescent compounds
IPC: C09K11/77
Filed: 1962-02-12
Abstract: Luminescent compounds having the formulae WO3.M2O3, where M is yttrium or lutetium are prepared by ultimately mixing, in the dry state, the equimolar quantities of oxides of tungsten and yttrium or lutetium, pressing the mixture into the desired shape and heating between 900 DEG -1400 DEG  C. in a non-reducing atmosphere such as static air.  Instead of the oxides chemically equivalent amounts of compounds which are converted to the oxides on heating may be added. Examples in the cases of yttrium and lutetium are the carbonates, oxalates, hydroxides, acetates and citrates. Examples in the case of tungsten are tungstic acid, ammonium tungstate and organic derivatives of tungstic acid.  Luminescent compositions are formed from a mixture of one or both of the tungstates together with a binder.ALSO:Luminescent compounds having the formulae WO3.M2O3 when M is yttrium or lutetium are prepared by intimately mixing in the dry state, the equimolar quantities of oxides of tungsten and yttrium or lutetium, pressing the mixture into the desired shape and heating between 900-1400 DEG  C. in a non-reducing atmosphere such as static air.  The compounds of the invention luminesce upon excitation by X-rays, cathode rays and ultra-violet radiation, and can be mixed with bindo and solvent and formed into luminescent screens.  A composition for use in fabricating an X-ray screen can be prepared by dispersing 55-57 parts of finely ground WO3.Y2O3 in a solution of 5 to 3 parts of nitrocellulose and 1 to 3 parts of plasticize therefor dissolved in 40 parts of an equal weight mixture of n-amyl acetate and u-butyl acetate; the resulting composition is cast on to a thin protective film of nitro cellulose, partially dried and a backing layer, e.g. of cardboard is applied.

Filed: 1927-03-01
Abstract: 284,875. Hellstrand, E. A. March 1, 1927. Guiding vertical, play; springs, arrangement of. -A vehicle axle is mounted to slide vertically in horn plates or equivalent guides exerting a frictional resistance which may be regulated automatically or otherwise, driving and braking torque being also resisted frictionally and elastically. In the construction shown in Figs. 1 and 2, the axle casing 5 is externally splined and engages slidably a sleeve 9 having radial extension 10 in front of and behind the axle. The axle and sleeve pass through a slot 3 in the frame, allowing freedom of movement in all directions. The arms 10 are connected by pivots 12, 14 embodying elastic material 16, with a plate 11 adapted to fit tho V-shaped vertical slides 7 fixed to the vehicle frame 2, frictional material 13 being interposed. The plate 11 is pressed on to the guides 7 by a helical spring 18 encircling the axle and enclosed by a tubular sleeve 20 having an inclined end 21. A seat 31 for the bearing spring may be provided on the sleeve 9. Torque reaction due to acceleration or braking of the vehicle may cause the plate 11 to ride up the ridges, against the resistance of the spring 18. This action may be avoided by making the ridges of rectangular section, as shown in Fig. 3. in which independently sprung wheels are employed. The axle casing 39 is applied to a sleeve 40 having integral therewith a friction plate 41, which bears against the fixed plate 6, frictional material 18 being interposed. The sleeve 40 is further guided by flanges 42 bearing against strips 35 backed by elastic material 34 in channels 33.

Abstract: 1427795 Titration apparatus; determination of bicarbonate in blood serum H DAHMS 6 Feb 1973 5748/73 Headings G1A and G1B In apparatus for colorimetric titration of a liquid containing an indicator substance having different light absorption characteristics on different sides of a colour change interval indicative of a predetermined end-point, light is passed through the liquid while a titrant ion is introduced thereto, first and second electrical signals are generated respectively corresponding to the intensity of light passing through the liquid at a first and a second wavelength respectively corresponding to the light absorption characteristics of the liquid at one side and at the other side of the colour change interval, and a third signal is generated corresponding to the ratio of the logarithms or the logarithm of the ratios of the first and second signals so that the titration is stopped when the third signal reaches a pre-set level. As shown, the liquid 12 contained in a transparent container 13 is a mixture of human blood serum, aqueous chloride-free titration solution and a small amount of a pH indicator e.g. phenol red. Titrant ion is introduced by electrolysis using electrodes 14, 16. As the titration proceeds, the end-point of the titration of chloride with electrolytically generated silver ion at the silver anode 14 is determined by amperometric electroder 17, 18. However, the electrolysis is continued to generate hydroxyl ions for titrating the remaining acid in the liquid. This end-point is determined colorimetrically by detecting the light passed. through the liquid at the two different wavelengths, determined by filters 205, 206, using photo-cell detectors 215, 216 which provide the first and second signals. The logarithmic ratiometer 210, Fig. 2 (not shown), provides the third signal, corresponding to the ratio of the logarithms of the first and second signals, to a meter relay 47 which acts to stop the electrolysis and a timer 49 when the pre-set level is reached. As an alternative, a single light detector can be provided with the two filters arranged in a rotating chopper. A synchronisation signal can then be provided with appropriate gating circuits and smoothing capacitors to separate the two signals before they are fed to the ratiometer. Further, the two filters can be provided in front of the container. As further alternatives, the titration can be performed using titrant liquid either manually or automatically in which a motor driven piston gradually forces the titrant liquid from a burette. Digital read-out may be obtained by a circuit in which the motor of the timer (or of the burette piston) drives the movable contact of a potentiometer to continuously change its output voltage which is amplified and displayed on a digital voltmeter.
