Filed: 1921-04-19
Abstract: 183,240. Hewett, F., and Giraud, A. A. April 19, 1921. Stoppering.-Apparatus for sealing and stoppering bottles &c. comprises a screw rotatably-' mounted in a barrel and provided with a socket for the reception of capsules &c. A hollow rod D slidably mounted in a barrel A is connected to a screw D<1> which extends upwards through a cap D<3> secured to the barrel A and carrying a ratchet D<5> held against rotation in one direction by a pawl and provided with threads which engage the screw D<1>. A collar D<10> and spring D<8> keep the screw in position in the barrel A. Within the rod D a collar E<4> frictionally held by a spring E<5> has projections which engage grooves E<2>, E<3> on a slidable spindle E to rotate it and a holder F, which slides in it, relatively to the rod D. The bottle to be closed is placed beneath a mouthpiece H fixed to the barrel A which is drawn downwards by a treadle, which also moves to one side a stop G to allow the spindle to descend. The mouth of the bottle forces apart pivoted jaws H', H<2> in the mouthpiece thus allowing the capsule C<2> resting thereon to drop on to the bottle mouth, the movement of the jaw H<2> forcing a tongue H<3> into a recess H<4> to allow a fresh capsule to enter the machine from the shoot J. The collar E<4> rotates the spindle E, and therefore the capsule, until internal projections in the capsule engage recesses in the bottle neck when, as the barrel descends, the holder F enters a cup E<1> on the spindle E and the screw D<1> is checked by the bottle and rotates screwing the capsule to place. On raising the barrel, the ratchet D<5> rotates and not the screw D<1>, so that the capsule is not unscrewed.

Title: Improvements in or relating to flow control apparatus
IPC: G05D11/13
Filed: 1966-03-15
Abstract: 1,145,354. Electrical weighing means. R. D. LINVILLE. March 15, 1966 ,  No. 11362/66. Heading G1N. [Also in Division G3] In an error-actuated system for automatically maintaining a rate of flow in correspondence with the rate of change of a variable, the error signal is derived from an electrical bridge circuit in which potentials are established corresponding to the magnitude of the variable and the integral of the rate of flow. In Fig. 1, dry fertilizer ingredients in hoppers 10-13 are fed by screw conveyers 16-19 to a mixing screw conveyer 34 and the mixture elevated by a bucket conveyer 38, which also mixes by back-legging, to a further screw conveyer 50 which supplies a truck 56. The hoppers are supported by weighing machines 28-31 which operate potentiometers to produce electrical signals corresponding to the weights of materials in the hoppers. In the arrangement described, a number of these weight signals is used to control D. C. motors driving the screw conveyers so that the materials are supplied from some hoppers at rates which are maintained in fixed ratios with the rate of supply from a selected uncontrolled hopper. In the electrical control system, which is described in detail, the weight controlled potentiometers are arranged in bridge circuits with preset potentiometers and the initial filling of each hopper is automatically terminated when the associated bridge circuit is balanced, indicating that the hopper contains the desired amount of material. Motors 22-25 are then run at fixed speeds for a predetermined time sufficient to fill the screw conveyers. The speeds of motors are then quickly adjusted to approximately correct speeds by follow-up servomotor systems controlled by the preset set potentiometers previously utilized for determinging the amounts of material supplied to the hoppers. The speed controlling servomotors, which control the tappings of auto-transformers supplying motors 22-25 through rectifiers, are finally put under the control of the weight-responsive potentiometers. One of the hoppers is chosen as a reference and its weight-responsive potentiometer forms a potential divider with its preset potentiometer. The potential from this divider is then compared with each of a number of similar dividers associated with other hoppers, and any differences, indicating deviation of the relative feed rates, are applied through amplifiers and relays to control pulsed operation of the speed controlling servomotors to correct the deviation. The speed controlling servomotors may be controlled by adjusting the preset potentiometers manually or automatically in dependence on moisture content. Relays ensure that motors 35, 46, 52 driving the uncontrolled conveyers can only be switched on in a predetermined sequence so as to prevent feed to an inoperative conveyer.

Abstract: 178,865. Bopp & Reuther. April 23, 1921, [Convention date]. Liquid-level pressure gauges; with recording apparatus.-In differential liquid-level pressure gauges of the U-tube type for use in connection with Venturi meters for indicating the flow of liquids, and fitted with float-operated recording apparatus, the movements of the float being made proportional to the square root of the differential pressure by having one limb of the U-tube parabolic in shape, this limb is made of considerably larger cross-section above the parabolic part than the other limb, which contains the float, so that approximately correct linear readings can be obtained throughout the whole range. The lessened movement of the float which results is compensated for by magnifying the movement in transmitting it to the recording pen. The parabolic limb b is concentric with the inner float-carrying limb a'and connected with it by means of tube d, vessel c, and slots h, and is in communication with the higher pressure. The sectional area of this limb above the parabolic part is large compared with that of the inner limb, and the practical zero line n, n of the mercury level, which determines the smaller divisions of the recording paper proportional to the square root of the differential pressure, is brought very close to the theoretical zero-line N, N which determines the remaining divisions.

In a character reading device characters to be read are first centred in the sensing field, the character being electrically simulated in a limited plane field of current or potential by impressing on those points of the field corresponding to areas of the character a predetermined voltage or current and measurements are taken of the currents flowing towards the marginal zones, or of the differences in potential between the character points and the marginal zones, and the results are fed to a control system for the alignment or centring of the marks or characters. The field may be formed by a network of resistors R, Fig. 2, the crossing points of which are assigned to the elements b(xy) of a raster pattern, Fig. 1, in which the mark to be aligned is imaged. The edges of the network are all connected to earth, the raster pattern is scanned by one or more photo-cells and the currents are used to impress a corresponding current or voltage on those points of the field. Points P(xy) are found which, when the character is in the centre, have a symmetrical electric field extending towards two or four marginal zones as shown in Fig. 4. If the character is offcentre the current field is unsymmetrical as shown in Fig. 3. The current densities are measured to derive control signals which are used to displace the character within the raster pattern to reduce the asymmetry.
