Title: Method and apparatus for refining molten glass
IPC: C03B5/225
Filed: 1972-04-04
Abstract: 1360916 Refining molten glass OWENSILLINOIS Inc 4 April 1972 [2 April 1971] 15265/72 Heading C1M Molten glass is refined by introducing the glass into a cylindrical chamber 35 formed within a container 10 which is rotatable about a central axis and rotating the container so that the glass forms a paraboloidal void and centrifugal force causes gaseous inclusions in the glass to migrate to the void. The container has an inlet 14 at its upper end and a discharge 15 at its lower end, each being coaxial with the axis of rotation, so that unrefined glass can be continuously fed into the inlet 14 and refined glass removed from the discharge 15 while the container 10 is rotating. A plate 30 having a series of radially extending openings is provided below the inlet to direct glass towards the container walls. A second plate 16 having openings adjacent its periphery extends across the chamber above the outlet to direct glass towards the container walls and thus to an area of higher centrifugal force thereby modifying the forces acting on the gaseous inclusions so that they tend to move towards the void. The container is preferably maintained with its rotational axis vertical or nearly vertical during operation.

Title: Improvements in and relating to multiplying and integrating mechanisms
IPC: G01B5/26
Filed: 1931-05-27
Abstract: 379,726. Integrating-mechanism. GROVES, W. W., 30, Southampton Buildings, London.-(Pintsch Akt.-Ges., J. ; 71, Andreas Strasse, Berlin.) May 27, 1931, No. 15544. [Class 106 (iv).] A multiplying and integrating mechanism particularly applicable to gas meters for reducing the registration of a volume gas meter for gases of variable condition to standard condition comprises a friction wheel arranged to run on a surface of revolution generated by a circular arc, the wheel being carried on an arm adapted to swing about an axis which touches the circle on which the centres of the meridians of the running surface lie. The gas meter (not shown) rotates the running surface 11 on which bears the friction wheel 6, Fig. 2, that is coupled with a counting-mechanism 7. The friction wheel is mounted on an arm 8 pivoted on a shaft 9 and controlled as regards its angular position by means of a cam lever 20 the position of which is determined by means of a logarithmic mechanism in accordance with the value of the quotient <p>/t where p is the absolute pressure and T the absolute temperature obtained by the use of known measuring instruments. In order that the friction wheel may take up its new position automatically it is mounted as shown in Fig. 4 on a stirrup member 57 supported on an axis 60. The member 57 carries an extension 59 co-operating with the forked end of a member 40 mounted on an axis 36 and controlled by the cam lever 20. Movement of the member 40 inclines the friction wheel thereby causing it to move it to the new position. A modification of the mounting is shown in Fig. 5, wherein the friction wheel is suspended from the member 40 by pivots 54, 56. The counter mechanism is actuated by a cam 53 on the friction wheel rocking a spring controlled lever 50 that is connected by a ball and socket joint in the line of the axis 36 to a pair of pawls driven by a ratchet wheel on the counter spindle.

Title: Improvements relating to locking means for screw-threaded elements
IPC: F16B39/30
Filed: 1941-12-03
Abstract: 555,123. Locking screws and nuts. EVERY, C. E. (Illinois Tool Works). Dec. 3. 1941, No. 15598. [Class 89 (i)] [Also in Group XXII] In a self-locking screwthreaded element the screw thread is depressed locally from its normal shape so that the complementary thread with which it engages is progressively deflected during rotation. The flank 38, Fig. 1, of one turn of the thread decreases in slope. from the point indicated by the line 2-2 to that indicated by the line 6-6 whilst the flank 40 of the adjacent turn progressively increases in slope. Beyond the line 6-6 the slopes of both flanks progressively return to the normal. When screwed into a nut or like member the depressed portion causes a bending of the thread 46, Fig. 5 to a buttress shape and then back to normal as the deformed portion passes on. In a modification in addition to the deformation of the flank 38 at 36, Fig. 8, the flank of the next thread but one is deformed at 37. In a further modification the deformations are made on opposite sides of the same thread. The deformed part on the following side of the point of maximum deformation may be removed at 64, Fig. 22, leaving an abrupt edge 62, in this form unscrewing without destroying the thread is impossible. In other modifications a projection is formed in the V of one thread and this causes a slitting of the crest of the mating thread. The projection may be such that on unscrewing the slit portion is opened again and then reclosed or it may be so formed that unscrewing destroys the thread. The threads are produced by cutting between platens 68, 70, Fig. 23, provided with recesses 82 at the parts where the deformations are to be produced, the recesses being spaced one pitch circumference apart. The earlier recesses produce unfinished parts on the thread, but the later recesses have die inserts 76 complementary to the deformation required. Holes 80 are provided behind the inserts to facilitate their removal when'necessary.

IPC: B41B25/00
Filed: 1916-11-02
Abstract: 120,243. Agger, E. E. Nov. 2, 1916. Strip - perforating machines; keyboards.- The key-leavers each set an individual interponent in engagement with a punch and a driving-device, the punch being operated on the return of the interponent by the driving-device. The mechanism may be arranged so that, on depressing any of the keys, the associated interponent is set but the operation of the associated punch is delayed until the next key is depressed, so that if an error is noticed as soon as the key is depressed, the delay enables the compositor to correct the erroneous setting before the punch is operated. In the machine shown, interponents 20 mounted loosely on a shaft 21 are each provided with a pivoted finger 27 for engaging the associated punch 10 and are each formed with arms 30, 23 for engaging a universal driving-bar 31 and a pivoted finger 24 on the association key-lever 2 respectively. The driving-bar is secured to arms on the shaft 21, which is provided with an arm 33 engaging a toothed wheel 57 on a frictionally-driven shaft 40. An escapement-wheel 41 on the shaft is controlled by an anchor 43 which is pivoted at 46 and is provided with a sliding latch 47 engaging a stop 48. The key-levers carry pivoted fingers 55 for operating a universal bar 53 carried by a shaft 49, an arm 50 on the shaft being provided with a pivoted finger 51 for operating the latch 47. On the initial part of the movement of a key, the anchor 43 releases the shaft 40 and the driving- bar 31 returns the interponent that had been raised by the preceding key. During the remainder of the downward movement of the key, the associated interponent follows the upwardly moving driving-bar 31 and is set in position to operate a punch, as shown in Fig. 3. In the setting movement of an interponent, the finger 27 yields and is then moved back by a spring 29 into engagement with the punch. An interponent that has been set in error can be returned bv hand without operation of a punch. The mechanism described above may be associated with the line-measuring and like devices described in Specification 120,215 and the strip-feeding devices described in Specification 120,244.

Abstract: 457,340. Thermionic valves ;amplifying and detecting circuits. JENSEN, C. A. SCHLEIMANN-, 56, Hyldegaardsvej, Charlottenlund, Denmark. May 30, 1935, No. 15814. Convention date, July 6, 1934. [Classes 39 (i) and 40 (v)] An amplifying or rectifying arrangement comprises a valve in which the fraction of the electron stream caught by an electrode flows through an impedance thus effecting further control by potential variation, and in which the electron stream is concentrated and directed so that substantially the whole electron current proceeds to the anode. The valve may have a pair of oppositely disposed control electrodes x, y which are both connected to the receiving circuit Fig. 6, or one of the electrodes may be held at fixed potential, Fig. 7 (not shown). The input is connected in series with the impedance R1 which produces the potential which effects the further control. Fig. 3 shows an arrangement in which the electrons are concentrated by a cylinder d and a single catching electrode s is employed associated with an anode a2 and a negatively charged electrode r which reflects the electrons back to the catching electrode. The control may be further increased by the provision of a grid e connected to the electrode s. Fig. 5 shows an arrangement in which a screen grid f and a suppressor grid are employed. An accelerating electrode a1 may be provided between the concentrating electrode and the control electrode. The potential of the concentrating electrode may be varied by manual or automatic means to control the sensitivity as by using the voltage across the impedance R1. Reaction may be employed by backcoupling to the input the anode circuit Fig. 7 (not shown), or an auxiliary anode or accelerating electrode circuit.

Title: Dry separation of starch and protein from flour or antecedent milling stocks
Inventor: JONES CHARLES ROBERT
IPC: A21D2/26
Filed: 1956-05-24
Abstract: Fractions of high protein content and low protein content are obtained from flour by subjecting the flour to comminution e.g. in a disintegrator of the impact type, such that starch granules embedded in a continuum of protein are released without being damaged and the continuum is fragmented into particles the majority of which are less than about 20 microns in diameter, and then classifying the flour to obtain a high protein fraction consisting of particles no larger than 13 to 15 microns and a low protein fraction consisting of particles larger than 15 to 22 microns and smaller than 28 to 40 microns.  The classifying into fractions may take place after each comminution or once only after a series of comminutions, particles larger than 28 to 40 microns being resubjected to comminution with further flour or, ultimately, discarded.  Any particles smaller than 13 to 15 microns may be separated from the flour before comminution and added to the fraction of high protein content obtained.
