Title: Improvements in or relating to the measurement or indication or/and recording of fluid flow rates
Inventor: WORSWICK BERNARD AUGUSTINE
IPC: G01F1/704
Filed: 1956-12-19
Abstract: 846,125. Radio-active measurement of fluid flow rate. BAILEY METERS & CONTROLS Ltd. Dec. 18,1957 [Dec. 19, 1956], No. 38672/56. Class 40(3). The rate of flow of a fluid stream is measured by timing the passage of an induced radio-active isotope over a known length of stream. When the rotating neutron absorption shutter 7, driven by the motor 8 and comprising alternate layers of cadmium and aluminium is in either of two angular positions separated by 180 degrees, neutrons pass from the source 4 through the two radiation windows 6 to bombard the fluid stream e.g. water, producing an unstable nitrogen isotope from the oxygen atoms in the water. At the same time the bi-stable multivibrator 10 is subjected to a pulse from switch 9, also driven by the motor 8 and assumes one of its stable operating conditions. The gamma radiation emitted by the isotope is detected at a downstream point by the scintillation counter 1, its output is differentiated at 11 and triggers the multivibrator back to its original condition. The multivibrator output pulse is applied to an averaging circuit 12 which has an output which is a function of the pulse length and hence the rate of flow of the stream. This is measured by meter 13 and/or recorded at 14.

Abstract: 844,736. Lampshade mountings. BUSSE, H. Dec. 1, 1958 [April 26, 1958], No. 38679/58. Class 75(2). Means for attaching a shade or the like to a lampholder comprise at least two retaining springs each of which has two linbs situated in a plane tangential to the surface of the lampholder with the limbs of each spring oppositely inclined at acute angles to a line parallel to the axis of the holder. The springs 15 may be attached to the lampholder 10 itself, to a sleeve 17 surrounding it (as in Fig. 1), or to a collar screwed on or in it. The lower limbs 18 of each spring are compressed as the shade 16 is attached and the upper limbs 19 clamp the shade from within against the surface 14 to which the holder is attached (as shown) or against the rim of a dome-shaped cover arranged above the lampholder as in Fig. 2 (not shown). As viewed in a direction normal to the plane of contact the springs are cuneate, triangular or trapezoidal ; in cross-section they may be rectangular and formed as stampings, or circular or of other shape and made from wire or the like. A protective covering may be fitted on the springs at least in the region where they contact the shades. To avoid the tendency to rotate the spring-supporting member particularly for the case when the latter is a screw collar, the springs may be formed as double springs with two pairs of limbs, the pairs being symmetrically disposed about the line parallel to the holder axis.

Title: Improvements in or relating to machines for preparing fibrous materials for spinning
IPC: D01G9/00
Filed: 1930-12-29
Abstract: 365,752. Hopper feeding and opening machines. RUSHTON, J. L., Kay Street Works, and SCHOFIELD, C., 63, Knowsley Road, Smithills, both in Bolton. Dec. 29, 1930, No. 38987. [Class 120 (i).] In hopper bale breakers, hopper feeders, and like machines for use in the preparatory treatment of fibrous materials for spinning, a feed mechanism 15, 16, 17, Fig. 1, is provided between the inclined spiked lattice 7 co-operating with a stripping roller 11 and the inclined or horizontal spiked lattice conveyer 12, the fibrous material being guided to and passed through the feed mechanism in such a manner that as it is presented to the lattice 12 it is lightly held and undergoes a supplementary opening and combing by the spikes of the lattice 12. The feed mechanism comprises an adjustable guide-plate 15 and a toothed, plain or fluted feed roller 17. The guide-plate 15 is pivoted at 16 at or near the top of an under-casing 14 which prevents cotton not stripped from the lattice 7 by the roller 11 from falling clear. Alternatively the plate 15 is mounted in slots in the machine framing so as to be angularly adjustable. A top guide-plate 23 adjustable independently of the plate 15 is also pivoted at 16 and when excess of cotton is being fed can be set so as to divert part back to the lattice 7. A feed-plate 21 having a toe 26 is also provided and is adjustably mounted with relation to the lattice 12 and feed roller 17. When the guide-plates 23, 15 are set as shown in full lines, Fig. 1, the cotton removed from the lattice 7 by the roller 11 falls on to the roller 17 and is fed against the plate 21, and while held thereby is combed and opened by the spikes of the lattice 12. When it is desired to omit this supplementary combing the plate 15 is raised and the cotton passed behind the plate 21 to the lattice 12. In a modification, the guide-plate 15 is pivoted at the top edge of the catch-plate 14, the roller 17 is fluted and the plate 21 made larger. In a further modification, the plate 15 rests in its lowest position against an adjustable stop 28, Fig. 3, the feed-plate 21 is adjustably mounted below the roller 17 which rotates in the opposite direction. The roller 17 may be fluted. In a machine having a pneumatic exhaust system the catch-plate 14 is perforated and a similar catch-plate 33, Fig. 5, mounted below the lattice 12, a supplementary guide-plate 34 being pivoted at 35 ; while in a modification, Fig. 6, the lower parts only of the plates 14, 33 are perforated, the plate 33 abutting against the plate 14 and the guideplate 15 being pivoted at its lower end 16a or the top edge of the feed-plate 21. The roller 11 serves both lattices 7, 12 and the cotton is thrown on to a dust-cage 37 having a stripping roller 39.

Abstract: 1,163,268. Driving piled structures. A. G. BODINE. 5 Sept., 1966 [4 Oct., 1965], No. 39628/66. Heading E1H. A complex structure 41 (Fig. 3) comprising a plurality of longitudinal members 45, 47, 49, 51, 53 and a connecting mass 43 (such as a prefabricated structure) is driven into a medium such as the earth by bringing one end of each of said members into engagement with the medium, generating longitudinal elastic vibrations in each of the members by at least one vibration generator or by an individual vibration generator 59, 61, 63, 65, 67 for each member, and discontinuing the vibrations when the structure has reached the desired position. Since a structural mass 55 renders structure 41 asymmetrical, a mass 57 is attached to structure 41 to render same synmetrical. In Fig. 6 longitudinal pile members 50, 52, 54, 56 to be driven into the earth have attached thereto or integral therewith a superstructure 58 on which is mounted a vibration generator 60 comprising prime movers 62, 64 on a common base 66 and driving vibrators 68, 70 imparting sonic vibrations to the whole structure in a longitudinal (vertical) direction. Lateral or parasitic vibrations transmitted to the laterally extending superstucture 58. Damping is provided by a container 98 filled with lead shot, sand or iron junk. To obviate driving energy being dissipated in the superstructure, the longitudinal members may each have a decoupling member 22 (Fig. 7) attached thereto above the vibration generator. Instead of the dampening means 98 of Fig. 6, the superstructures can incorporate inlays 120, 122, 124, 126 (Fig. 7) or a special aggregate 127 may be used in the case of concrete structures.
