Abstract: 637,302. Making tubes. RADAELLI, U., and BERTOLI, E. Dec. 12, 1946, No. 36711. Convention date, April 26. [Classes 83 (ii) and 83 (iv)] Angular bending and curving.-A machine for bending plates into cylindrical or conical tubes comprises a first group of two external and one internal rolls (Fig. 3, not shown), subsequent groups of one internal and one external roll alternately disposed at the opposite plate edges (Figs. 4, 5, not shown), further groups of external rolls co-operating with shouldered rolls (Fig. 6, not shown), and finally regularizing groups of rolls all acting externally of the closed tube (Fig. 7, not shown). All the rollers are arranged for radial displacement relative to the centre of curvature of the plate at any stage and in the case of concave and convex rollers the planes normal to their axes passing through their pivot points of minimum and maximum radius respectively are arranged to contain the axis of the finished cylinder or cone. The bearings of the three roll group, Fig. 8, are adjusted radially by pinion carrying screws 1 rotated by a gear-ring 17 rotatably mounted on the frame and carrying a toothed sector 19 alternatively rotated by transmission shafts 21 through clutches operated through a lever 22 and toothed segments 23 engaged by pawls on the plate-carrying chain. Change wheels are provided for varying the ratio of roll displacement to plate feed for producing differentlyshaped plates. Alternatively the rolls may be adjusted by rollers engaging cam slots or profiles in or on the ring, see Fig. 12, not shown. The shouldered roll comprises a central part fitting the space between the tube edges and two side parts with straight or curved profiles decreasing in radius towards the centre, which shape the plate edges for lapping or butting. The plate is drawn through the rolls by vices secured to a chain which engage abutments to automatically open and close the jaws, Fig. 10, not shown. The jaws are spring-closed and a cam is arranged so that their grip increases with the pull in the chain. Specification 632,996 is referred to.

Title: Improvements in and relating to apparatus for measuring static forces
IPC: G01L1/02
Filed: 1958-11-14
Abstract: 871,075. Indicating-apparatus; dynamometers and pressure gauges. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. Nov. 14, 1958 [Nov. 16, 1957], No. 36745/58. Addition to 871,074. Classes 106 (2) and 106 (4). The invention of the parent Specification is modified in that the supplementary restoring force becomes inoperative beyond a predetermined deflection of the indicating means. As shown, Fig. 4, the restoring force provided by a pendulum 39 is supplemented by the resultant effect of two weights 49, 52, carried by a pulley 45. As the deflection of the pendulum 39 increases, the effect of the weight 49 decreases due to the shortening of the effective lever arm carrying it and it is entirely counteracted by the weight 52 as soon as the steel tape 47 contacts the periphery of the pulley 45.

Filed: 1961-10-16
Abstract: <PICT:0998302/C1/1> In a method of glass-lining metallic pipe fittings a glass liner 13 is inserted into the bore 12 of the fitting 10 and at least the glass liner 13 is heated until it becomes viscid when it is radially expanded into engagement with the bore 12.  As shown the fitting 10 which has flanges 14, 19 is closed at one end by a closure member 26 and has an extension member 20 provided with a liner of asbestos or other material to which glass will not adhere attached to the other end.  The fitting is preferably coated with at least one ground glass coat 11 after which the glass liner 13 is inserted.  The whole assembly is heated and when the glass liner has reached its softening point air pressure is applied through tube 31 so that the liner 13 engages with and fuses with the coating 11.  The members 20, 26 are removed and the end surfaces of the glass liner and metal fitting are ground to provide smooth gasket facing surfaces.  In another embodiment a tee-shaped fitting is lined with glass by a similar method.  The lining is done in two stages, a first glass liner is inserted, heated and radially expanded, the air pressure being maintained in order to rupture the glass liner at the point of intersection of the bores of the fitting.  A second glass liner is inserted into the other bore until the closed end is adjacent the point of intersection of the bores.  The second glass liner is heated and radially expanded, the air pressure being maintained until the closed end ruptures.  The ruptured portions of the two glass liners overlap to provide a substantially uniform glass lining.

Title: Improvements in or relating to producing yeast
IPC: C12N1/18
Filed: 1929-12-04
Abstract: Yeast is manufactured by the aeration method with periodical addition of the nutrients, the propagation of the yeast being divided into partial fermentations of increasing volume directly following each other and each of which constitutes a fully accomplished fermentation phase.  At the beginning of each phase the entire nutrient solution required for that phase is supplied to the yeast and the propagation is in every one of such phases carried on up to the full consumption of the fermentable sugar introduced at the beginning of the phase. The yeast produced in one phase is used without separation as starting yeast for the next phase, and the quantity of nutrient substance supplied to the yeast at the beginning of each phase is calculated so that the quantity of yeast increases in each phase, through all stages of fermentation for a determined amount increasing from phase to phase, which is determined by the ideal condition that the quantity of yeast ought to increase throughout logarithmically with the time, corresponding to the fundamental equation q=aed t where q is the amount of yeast present after the time t, a the quantity of yeast employed for starting the propagation, e the base of the natural logarithm and d  the factor of growth, which according to the quantity and yield of yeast aimed at lies between the limits 0,05 and 0,22.  The total duration of the propagation process being advantageously chosen from 16-36 hours in from 5-9 phases.  Ripening intervals may be inserted at the end of the phases following the preliminary fermentation prior to further supply of nutrient substances and the duration of these intervals increases with the progress of the fermentation procedure.  Specification 299,336, [Class 14 (ii), Beverages &c.], is referred to.

[Also in Division G1] In an X-ray spectrometer for detecting the presence and measuring the concentration of a particular chemical element in any of several liquid samples, X-rays from a source 1, Fig. 1, are directed to a number of test cells 3, each containing one of the liquids and each associated with a dispersive element 4 arranged to direct to a detector 2 only that part of the secondary radiation emitted by the particular sample, characteristic of the particular chemical element, the detector being shielded from radiation from all but one in turn, of the dispersive elements. The test cells 3 are designed so that a flow of liquid can be passed through each, and that the volume of liquid in each cell is constant (Fig. 2, not shown). The source 1 is an X-ray tube provided with separate windows if four or less cells are arranged around it, or an annular window if more are used. Each cell has an X- ray permeable window, and secondary radiation emitted from a cell is collimated at 5 before the characteristic radiation of the element being determined is separated out by the crystal analyser 4 which focuses this radiation on to the detector slit. Separate shutters 6 or a single-apertured rotating disc is interposed between crystal 4 and detector, so that only one sample at a time is analysed. Pulses from the detector are indicated as radiation intensity at apparatus 7. Programming apparatus 8 controls the single shutter or shutters 6 and is connected to apparatus 7 for synchronizing the indication.
