Title: Improvements in nails, screw-nails and the like
IPC: E01B9/12
Filed: 1924-02-28
Abstract: 234,549. Lytton, E. Feb. 28, 1924. Screw-nails and the like; spikes ; nails, barbed. - Screw-nails, spikes, &c. are provided with one or more deformable strips or ribs towards the point, the strips being arranged lengthwise of the shank and after insertion of the screw-nail &c. are given a coiled form by rotating the shank. As applied to a spike g, Fig. 2, the strips h are inserted through a transverse hole i near the point and bent lengthwise of the shank. By rotating the spike the strips h, Fig. 4, are coiled round the shank and so prevent withdrawal of the spike. The strips may be formed integrally with the shank and be severed therefrom either before insertion by a cutting tool, or after insertion by shearing when the shank is rotated. The upper ends of the strips may be tapered. The hole in the shank may 'be provided with recesses and the shank with helical grooves to facilitate the coiling of the strips. The point of the shank is provided with a shoulder l.

Title: Apparatus for producing liquid gradients
IPC: G01N1/28
Filed: 1974-02-05
Abstract: 1404118 Liquid gradient generator INTERNATIONAL EQUIPMENT CO 5 Feb 1974 [8 Feb 1973] 05150/74 Heading B1C A generator for liquid gradients comprises two compartments 12, 14 with an inclined barrier 13, outlet apertures 15, 16 and conduits 18, 20, a delivery conduit 24 and a vessel 26 in which the gradient is to be established. The compartments are initially filled to the same level with different liquids; on discharge, the level will fall at the same rate in both whereby the ratio of the two liquids in the mixture will vary continuously. The sizes of the apertures 15, 16 and conduits 18, 20 are selected so that the outflow is controlled only by the chamber pressure and not by viscosity; the sizes may differ. In a modification (see Fig 2, not shown) the outlet conduits 18, 20 may be carried up to form a siphon; the mixture may be passed through a mixer (48); discharge may be assisted by a pump (49), and divided between a plurality of receiving vessels 26. If a denser liquid is placed in compartment 12 and a less dense in compartment 14, the less dense end of the gradient is produced initially and floats in the more dense phases which follow. In another embodiment, (see Fig 4, not shown) the compartments 12, 14 are rectangular and the inclined barrier provided by triangular prismatic inserts.  In a further embodiment, (Figs 5-9, not shown) the apparatus is formed as a detachable part of a vessel such as a test-tube, suitable for placing in a centrifuge. The application described is the formation of a concentration gradient of a super solution in normal saline for washing blood cells, but the apparatus may be used for making refractive index, ionic strength, viscosity, pH or optical density gradients.

Title: Apparatus for use in examining animal cells
IPC: G06T1/00
Filed: 1965-02-08
Abstract: Cancerous animal cells are identified by immersing individual cells in electromagnetic radiation and measuring the absorption thereof. The radiation has a wavelength, e.g. 2537  lying within the absorption band of nucleic acids (2500-2800 ) of which there is a greater concentration in cancerous cells than in normal cells. Simple comparison of the absorption with a preset standard is possible but liable to interference from cell debris and the variable size of cells.  It is preferred to irradiate the cell also with a wavelength, e.g. 3130  in a range absorbed by cell protein but not nucleic acids (2800-3200 ).  The two wavelengths are separated by a prism, filters or a dichroic mirror and pass to separate photomultipliers the outputs of which are fed to a difference amplifier.  In the arrangement of Fig. 3 (not shown) any of the following signals may be selected for recording or display:  (a) The output of either photomultiplier backed-off against a preset reference signal.  (b) the difference between these outputs backed-off against a preset reference signal  (c) the ratio of the outputs before or after backing-off.  (d) a combination of the backed-off signal from one photomultiplier with the backed-off difference signal.  The cells are part of a specimen located on a quartz slide movable for selection of the individual cell.

The actuating device and the arc-control device are both carried by the removable cover of the tank. In the single-break oil-switch shown the cover A<1> supports two insulating slabs E, E<1> carrying between them by means of brackets F<2> a metal cylinder F, the operating piston F<1> of which carries the movable rod contact D. Operating fluid is admitted to the ends of the cylinder F through conduits G, G<1> which pass upwardly through bores in the plates E, E' and may serve to convey current to contact D. The arc-control device C, which may be of the character disclosed in Specifications 435,250 and 435,308 is either mounted directly on plates E, E<1> or on the bushing insulator supporting the conductor B' leading to the fixed contact B. The conduits G, G<1> are led at the back of the device C in order that the electrodynamic effect of the current therein may force the arc into the vents C'. The sliding contact between F, F<1> and between D and a gland F<3> on the cylinder-head may be supplemented or replaced by a flexible connection or by a fixed sleeve in sliding contact with D. In a modification, Fig. 2 (not shown), the arc-control device and conductor leading to the movable contact may be arranged as described in Specification 460,219, the conduits being constituted simply by the bores in the insulating plates. The parts may alternatively be horizontally arranged.

Title: Improvements in or relating to the manufacture of strip iron
IPC: B21B45/04
Filed: 1954-02-24
Abstract: A scale-free or substantially scale-free iron strip is obtained by cooling the hot strip from the final hot roll to a predetermined temperature, leading the cooled strip through a gaseous pickling chamber and maintaining it in an inert atmosphere until cooled to a temperature below that at which scale will be formed.  The cooling from the hot roll may consist in spraying the strip with a controlled amount of water.  The speed of travel of the strip may be controlled to give a required structure to the strip or, during pickling, to produce a particular degree of descaling.  The pickling gas may be 1 part by volume hydrochloric acid gas, 2 parts by volume carbon dioxide, and 2 parts by volume nitrogen.  After cooling the strip may pass through a tank containing a solution of a phosphate to produce a corrosion inhibiting layer on the surface of the strip.
