Title: Improvements in landing nets
IPC: A01K77/00
Filed: 1959-10-19
Abstract: 962,104. Anglers' landing nets. R. SPENCER. Oct.19, 1960 [Oct. 19, 1959], No. 35296/59. Heading A1A. A landing net comprises a pair of hollow net supporting arms 14 pivoted to a carrier 12 slidable on a handle 10 from a stowed position near a hand grip 11 to an in-use position at the other end, and means for opening the arms when the carrier is in the in-use position. The means for opening the arms comprises a slidable spindle 22 which extends from a boss 23 mounted on the hand grip end of the handle; the spindle is turned back at its forward end and enters a bore in the forward end of the handle. The bore contains a spring which urges the spindle forwardly. The rear end of the spindle has a catch 24 which co-operates with slots 23b in the boss 23 to hold the spindle retracted. The arms 14 are actuated by a toggle system consisting of two pairs of bars 16, 17 pivoted to a slide bar 19 slidable on the spindle 22 and having a spring mounted rib 32 engaging a shoulder on a stop 29 on the forward end of the spindle 22. The carrier is held in forward position by a blade spring and stud 30a engaging a head 30 on the front end of the handle 10. In operation the carrier is slid manually to the forward end of the handle and the spindle 22 is drawn back to move the slide bar 19 and the toggle linkage to pivot the arms outwardly. The catch 24 is then engaged. Releasing the catch allows the spindle to be moved forwardly by its spring and, as the rib 32 is engaged with the shoulder of the stop 29, the slide bar 19 also moves forwardly to close the arms. To return the net to the stowed position the arms are first set in the open position and the carrier then slid back. The stud 30a first disengages from the head 30 to allow the carrier to move relatively to the slide bar 19 to close the arms. The rib 32 then disengages from the shoulder on the stop 29 so that the carrier and slide bar can be slid along the handle. The slide bar 19 is assisted in sliding rearwardly relative to the carrier by a spring T located between a lug 25 on the carrier and a sleeve 26 which slides on the spindle 22 and abuts on end 21 of the slide bar. A blade spring 27 secured to the carrier has a rib 27a which is forced into engagement with the end of the sleeve 26 by a bolt 19a. When the slide bar is moved rearwardly the rib 27a disengages but when the carrier is moved rearwardly the rib 27a remains engaged. The carrier has a U-clip 28 for engaging the angler's belt; The opening of the clip can be varied by a screw and spring 28a; the clip may swivel. A bead coated with luminous material and a wire guard may be mounted at the end of each net arm. The front of the net is supported by a cord which passes into the hollow arms and is resiliently mounted therein.

Title: Improvements in or relating to knitting machines
IPC: D04B9/26
Filed: 1946-12-03
Abstract: 653,673. Knitting-machines. HEMPHILL CO. Dec. 3, 1946, No. 35798. Convention date, Dec. 8, 1945. [Class 74 (ii)] Selecting mechanism to effect patterning in articles knitted on a circular machine comprises two vertical banks of selector blades actuated individually by levers engaged by a pattern drum, the operative blades engaging needle jacks to select the needles required to take the appropriate yarn. As described, the two banks of blades permit two selections of needles for each course of knitting, the selected needles receiving wrap yarns. The pattern drum comprises a number of discs 20 provided with butts 21, the butts on each disc being engageable with a butt 18 on a corresponding lever 17 slidable towards and away from the needle cylinder. Each selector blade 5, 6 of each bank of blades is adapted to be engaged by an arm 14 of a rocker member 12, another arm 16 of which abuts the end of the lever 17 so that movement of the levers 17 withdraws the blades from the path of the needle jacks against the action of springs 9 urging the blades towards the cylinder. A rotatable shaft 22 having an elliptical body is positioned between a third arm 24 of the rocker members so that rotation of the shaft 22 actuates the rocker member to withdraw all of the blades. Alternatively, or in addition, a cylindrical shaft 25 having flats 27 extends through and engages the side of an opening in the levers 17 so that rotation of the shaft 25 moves the levers 17 to withdraw all of the blades or selected groups as determined by the flats 27 on the shaft 25. A unit comprising two banks of blades is disposed at two positions around the needle cylinder to effect the selection of needles during both rotary and reciprocatory knitting. Two pattern drums are provided one for each unit and both are driven by common mechanism from the gear as d scribed in Specification 653,728. During a course of knitting selected needles may be raised by the first bank of blades to receive a wrap yarn and then lowered and a second selection of needles may be made by the second bank of blades, all of the needles then knitting at the auxiliary cam block. Independent operation of each bank and each blade permits the operating space to be confined to a width slightly larger than the width of the selector blade. Specifications 370,023, 519,867 and 519,868 also are referred to.

Abstract: 969,119. Metals cleaning; stainless steel. DOW CHEMICAL CO. Sept. 21, 1962 [Sept. 27, 1961], No. 35985/62. Heading C7E. Stainless steel is cleaned and freed from mill scale and welding oxides, by contact with an aqueous acidic cleaning composition which contains fluoride ion or fluoride and nitrate ions; together with one or more acidic metallic oxides dissolved therein. The acidic metallic oxide is preferably CrO 3 , used with aqueous hydrofluoric acid or an aqueous solution of hydrofluoric and nitric acids. Other acidic oxides specified are of Mn, Fe, Mo, W, U, V, Nb or Ta. The fluoride ion may be derived from a water-soluble fluoride, e.g. ammonium bifluoride, sodium fluoride, sodium acid fluoride, potassium fluoride, potassium acid fluoride, hydrofluoric acid or mixtures thereof. The amount of acidic oxide added may be calculated by testing a series of concentrations and plotting a graph, which shows a "peak" for the optimum amount required for minimum corrosion. The concentration of fluoride ions may range from 1-50% by weight and if nitric acid is present its concentration ranges from 1-70% by weight. The acid anion may be added in concentrations up to 6%. In an example, a solution comprises 4% HF, 25% HNO 3  and 1-3% chromic acid. Solution temperatures range from 24-60 ‹C., preferably 27-49 ‹C.; for immersion times of 2-8 hours with agitation ; alternatively the solution may flow over the surface of the stainless steel.

Filed: 1960-10-20
Abstract: 967,583. Generators operating by electromagnetic interaction with fluids. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 20, 1961 [Oct. 20, 1960], No. 35999/60. Heading H2A. In a magnetohydrodynamic generator a highspeed jet of hot partially ionized gas or vapour interacts with the radial components of the magnetic field present at the ends of a heat resistant tube on which a coil is wound and the degree of ionization, velocity or temperature of the gas cyclically varied to induce A.C. in the coil. The gas may be ionized by applying high A.C. voltage to an ionizing winding external to the tube or a high D.C. voltage to electrodes in the inlet end of the tube, by injecting a beam of electrons into the tube or thermally, this last effect being enhanced by seeding the gas with sodium, potassium and the like. Temperatures of 2000‹ C. and conductivities of 100 mhos./ metre and operating frequencies of 500 cycles/ second are envisaged with a tube having an axial length less than its diameter when the latter is about 1 metre. In operation battery B passes D.C. through the coil L to produce a steady magnetic field in the tube. The cyclic variation of the gas flow or its conductivity when it interacts with the radial components of this magnetic field will produce varying currents in the gas and thus induce an A.C. voltage in the inductor which feeds the load if resistance r is small and inductance L<SP>1</SP> large compared to the load resistance and inductance. In an alternative system a capacitor is used to form a resonant circuit with coil L, the resonance frequency being half that of the frequency of the cyclic variation of the gas flow.
