Title: Method of and machine for producing fish hooks from wire
Inventor: OKHLYAND ALEXANDR BORISOVICH
IPC: B21F45/12
Filed: 1967-08-08
Abstract: 1,200,345. Making fish hooks from wire; bending. TSENTRALNOE PROEKTNO KONSTRUKTOBSKOE I TEKHNOLOGICHESKOE BJURO. 8 Aug., 1967, No. 36281/67. Headings B3A and B3E. A method of making fish hooks from wire includes swaging the wire 2 at intervals, cutting the swaged sections to form a blank having a sharp point at each end and bending an intermediate portion of the blank, forming barbs at at least one end of the blank and bending the barbed end or ends to form a hook. The wire 2 is fed from a drum 1 through a straightening mechanism 5 from which a carriage 21 of a feed mechanism 6 delivers it to a swaging mechanism 7 provided with strikers 22, 22<SP>1</SP>. After swaging the wire is fed to a device 8 in which cutters 23, 25 cut it into blanks and form sharp points at both ends of each blank. The blanks are simultaneously bent in the middle by a punch and die. The bent portion is located over a guide 28 and its ends rest on screws 27 and as the screws rotate the blank is transferred to barb cutting mechanisms 11, 11<SP>1</SP> where cutters 29, 291 successively cut the barbs on opposite ends. Instead of being bent, the blank may be swaged in the middle for centering on the guide 28 in the manufacture of flat end hooks. The blank is next moved by the screws 27 to a hook-forming mechanism 12 wherein two pairs of levers bend the ends of the blank on formers (33), Fig. 4 (not shown), after which pushers (34) move the blank along the formers (33) to a final shaping mechanism 14. In the mechanism 14, the bent centre portion of the blank is formed into a ring. Finally, the ends of the hook are set at an angle to each other, e.g. 120 degrees. When making single hooks, the blank is severed at its bent centre portion and the cut ends formed into rings.

Title: Improvements in and relating to measuring systems
IPC: G01T1/185
Filed: 1957-11-22
Abstract: 873,629. Radiation detector for thickness or density measurement. INDUSTRIAL NUCLEONICS CORPORATION. Nov. 22, 1957 [Dec. 18, 1956], No. 36546/57. Class 40(3) A system for measuring a variable characteristic, e.g. the thickness or density of material, includes a high impedence between the radiation detector and an electronic discharge tube, an adjustable voltage connected in opposition to that produced across the high impedance and a compensating variable voltage network which cancels, signals arising from variations in the input impedance of the discharge tube or compensates for unbalance due to grid current variations, e.g. when a tube is replaced. The current in radiation detector 10 develops a voltage across impedance 15 which is balanced in its application to the grid 51 of tube 24 by a variable potentiometer voltage at 17. The output of tube 24 stabilized by resistor-capacitor 29, 30 is fed to the grid of a tube 25, the anode of which feeds a voltage divider 38, 39 to give positive feedback to the screen grid of tube 24. The cathode load resistance of tube 25 comprises voltage dividers 31, 32 the mid-point 33 of which is connected through a meter 34 and variable resistance 36 to ground. The opposing voltage network 16 comprises three distinct elements, (a) a potentiometer 21 of low resistance and switches 42, 43 for effecting compensation with change of grid current, i.e. when the tube 24 is replaced, (b) a potential source 18 and highprecision calibration potentiometer 17 for bring- ing meter reading 34 to mid-point for standard thickness or measurement and (c) a standardization potentiometer 19 and fixed resistor 20 for correcting source type drifts, e.g. due to decoy of the radio-isotope source 11. With no material at 12 and the potentiometer 17 at its bottom end, the calibration potentiometer 19 is adjusted to give zero deflection at rotor 34. The potentiometer 17 is then calibrated for different thicknesses of material necessary for zero deflection. Potentiometer 27 has previously been adjusted to give zero reading with switch 22 closed. Closure of switch 22 is also used to check periodically on the drift of the amplifier. When switch 22 is open and a positive signal from the detector impressed on grid 51, the plate voltage of tube 24 falls and less current in cathode follower 25 results in point 33 becoming more negative. This potential cancels the positive signal on grid 51, allowing the latter to assume the voltage to maintain the necessary feed back. The potential registered on the meter 34 is a measure of the thickness variation. The meter can be replaced by a device automatically controlling the thickness of material 12. Specification 873,630 is referred to.

Title: Improvements in and relating to the measurement of thermal conductivity

IPC: G01N25/18
Filed: 1956-11-29
Abstract: 855,658. Determining thermal conductivity. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 29, 1957 [Nov. 29, 1956], No. 36588/56. Class 40 (1). [Also in Group XX]  In apparatus for measuring thermal conductivity the temperature change of a body when brought into contact with the material being tested, the body and the material initially being at different temperatures, is compared with the temperature change of a similar body in contact only with the ambient atmosphere. Fig. 1 shows a section through the apparatus in which two steel balls 11 and 12 are mounted in an insulating block 13. Ball 11 is slightly protuberant in order to contact the material under test, whilst ball 12 is recessed in order that it shall only contact the ambient atmosphere. The block is supported on the test material at only ball 11 and two studs, of which one is shown at 14. The temperatures of the balls are measured by thermocouples recessed into their surface and preferably the connections are such that the output is the difference in the e.m.f's of the thermocouples and hence a function of the temperature difference,  Measuring thermal conductivity of a fluid.- A shallow dish 17, Fig. 7, having branch tubes 18 for the introduction of temperature-measuring instruments or the introduction of the fluid under test, has a thin impervious membrane 21, stretched over its top so that a device 13, as described above may be placed on the membrane in good thermal contact with the fluid. In order to limit convection currents a member 25 is placed in the disc to keep the depth of the fluid below the membrane at a suitable value, e.g. 3 mm. For use with gases smaller or hollow balls may be used in order to reduce their thermal capacity.

Title: Process for the conversion of normally gaseous hydrocarbons into liquids
IPC: C07C9/14
Filed: 1937-07-29
Abstract: A normally gaseous paraffinic mixture is converted into gasoline by a process similar to that described in Specification 499,831, except that the whole of the gaseous and vaporous products of the first conversion stage or the separated intermediate products comprising C3-C5 hydrocarbons are subjected to the polymerization, the products are separated into the three groups of products, viz. fixed gases, gasoline, and hydrocarbons of 3 and more carbon atoms, this last product being returned wholly or in part to either the pyrolysis or the polymerization stage or in part to each stage.  When the whole of the pyrolysis products are sent direct to the polymerization stage, the tubular heating coil may be omitted and the enlarged polymerization chamber alone utilized.  The polymerization products pass to a fractionator where polymer gasoline separates from gaseous and vaporous constituents which are further cooled and condensed to yield more gasoline.  Uncondensed gases are washed with an absorption medium for C3-C5 hydrocarbons, the residual gases being discharged. The absorbed gases are recovered by heating and are recycled to the pyrolysis or polymerization stage or both.  The gasoline may be stabilized and the released gases also recycled.  U.S.A. Specification 1,987,007 is referred to.

Abstract: Fluorinated hydrocarbons are made by fluorinating a halogenated straight chain saturated C1-C4 aliphatic hydrocarbon containing at least one carbon atom carrying at least two halogen atoms of which one at least is chlorine or bromine, and containing no element other than carbon, fluorine, chlorine, bromine and hydrogen by heating it in the gas phase with gaseous substantially anhydrous hydrogen fluoride at a temperature of 225-650 DEG  C. in the presence of a catalyst consisting of dichromium trioxide and obtained by precipitating hydrous chromic oxide from an aqueous solution of a trivalent chromium salt and subsequently heating it to 300-400 DEG C. for not less than one hour. The process is advantageous for preparing carbon tetrafluoride, for example from a perhalogenated methane containing at least one chlorine atom, all the other halogen atoms being either fluorine or chlorine, at a fluorination temperature of 400-550 DEG  C.
