Title: Sewing machines
IPC: D05C15/00
Filed: 1930-11-07
Abstract: 362,615. Tufting-machines. FAIRWEATHER, W., 65, Chancery Lane, London.- (Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Nov. 7, 1930, No. 33490. [Class 112.] The looper of a hook-needle tufting-machine rotates twice for each needle reciprocation ; once to place the thread in the needle barb and a second time to create a slack in the thread by winding it around a retaining device. The thread loops are cut by a disc knife 101 which is rotatably mounted on the feeding foot. As the knife wears the thread forces it round against a friction washer to a new position. The needle is flattened on one side and makes sliding engagement with the knife. The retaining device, Fig. 14, comprises an arm 85 pivoted at 90 to an adjusting arm 91, and actuated by an eccentric 95. The looper 54 whips a length of thread about a nub 86 sufficient for the formation of a succeeding loop. To ensure that the length of thread is stripped from the nub, the vibrating arm 85 enters a recess in the throat plate. Specification 362,616 is referred to. Needles, vibrating laterally; feed by needles; feed by devices engaging the upper surface of the work.- The needle-bar 9 is journalled for reciprocation in a vibrating frame 12 which also carries the feed bar 26. The frame 12 is oscillated about a pivot 13 by a rockshaft 21 which is operated from the main shaft by an eccentric 23. The work is fed by the needle and a foot 24 which engages the upper surface of the work and is carried by the reciprocating feed bar 26. The feed foot, Fig. 9, is serrated on its lower surface and is slotted at 107 to clear the needle and at 108 to clear the thread. The presser foot 46 and feeding foot 24 are operated to engage the work alternately by a lever 53 against the action of a spring 47. Work guides.-A guide 111 pivoted the machine head 4 prevents the pile threads of a previously formed row passing under the feeding foot. The guide is curved to recede gradually from the line of the loops and from the normal to the work support.

Filed: 1962-08-31
Abstract: 959, 250. Measuring electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 3, 1962 [Sept. 29, 1961], No. 33568/62. Heading G1N. A freezing-point measuring apparatus, suitable for use in determining the osmotic pressure of a solution 7, comprises a thermistor 2 of which the temperature sensitive element is located in a bulb at the extremity of an upwardly-directed pointed member, the test solution 7 being confined in a receptacle defined by the pointed member and a tubular element 6, e.g. of polythene, force-fitted around it. The thermistor is connected as one arm of a D.C. Wheatstone bridge, the output current of which is fed to a recording millivoltmeter 17. The test solution 7, which is protected by a drop of petroleum oil on its surface, is supercooled within a tube 9 as by a cooling gas provided by the evaporation of solid CO 2  10, until the stylus of meter 17 is deflected sufficiently to close switch 15, thus energizing an electromagnet 14. An armature 13 is thereby deflected downwards against the action of a spring 24, and a member 12 of wood impregnated with petroleum oil, on which crystals of ice have formed, is plunged into the solution 7, which then freezes, and the stylus of the meter 17, which is calibrated in units of osmotic pressure, returns to a position determined by the freezing-point of the solution. A method of calibrating the apparatus is disclosed in the Specification.

Title: Improvements in decarburized silicon steel and method of producing the same
IPC: C21D3/04
Filed: 1958-10-21
Abstract: A method of decarburising silicon steel comprises heating the steel to 875 DEG C. to 1025 DEG C. in an atmosphere of a pure inert gas containing water vapour.  The steel should be given a clean bright surface by shot blasting and pickling in a hydrochloric/hydrofluoric acid mixture before decarburising.  The inert gas may be nitrogen, helium, argon, neon, or krypton and water vapour may be added to give a dew-point of between -40 DEG F. and 35 DEG F.  The decarburisation may be carried out during a stress relief anneal at 925-955 DEG C. It is stated that the carbon may be reduced to below 0,001%.

Title: Improvements in or relating to colour television apparatus
Inventor: TOWNSEND GEORGE BORIS
IPC: H04N9/69
Filed: 1960-09-30
Abstract: 929,474. Television. GENERAL ELECTRIC CO. Ltd. Sept. 29, 1961 [Sept. 30, 1960], No. 33695/60. Class 40 (3). The direct video signal output of a colour television camera 1 comprising simultaneously produced red, green and blue component colour television signals E R , E G , E B  ( having equal energies for " white ") are individually gamma corrected in 2, 3 and 4 and supplied to a matrix 5 in which is derived a luminance signal E<SP>1</SP>y (= 0.30E<SP>1</SP>R + 0.59E<SP>1</SP>G + 0.11E<SP>1</SP>B) and colour difference signals E<SP>1</SP>R - E<SP>1</SP>y E G <SP>1</SP> - E<SP>1</SP>y and E B <SP>1</SP> - E<SP>1</SP> y . The latter signals are supplied via individual amplifiers 6, 7 and 8 of restricted bandwidth (for economy) to individual grids of a tri-gun colour picture tube 9 and the luminance signal is supplied via an amplifier 10 and a delay device 11 (because of the restricted bandwidths of amplifiers 6, 7 and 8) to the cathodes of the tube guns. The invention may be employed to monitor the pictures produced by a camera tube or may form part of a closed-circuit colour television system an advantage over known systems in which the individual component signals are amplified at the camera output being that during the reproduction of " black-white " scenes the colour-difference signals are all of zero magnitude and the grey scale tracking is therefore independent of the relative gains of the amplifiers 6, 7 and 8. Switch means may be provided to connect the outputs of the gammacorrecting circuits 2, 3 and 4 in turn to the luminance amplifier 10 (the inputs to the matrix 5 being disconnected) to enable the colour component camera outputs to be separately monitored additional switch means being provided, if it is desired to produce the component in its correct colour, to render inoperative any two electron guns whilst the camera output corresponding to the other gun is being monitored. Instead of producing three colour-difference signals the matrix may be arranged to produce two only and a further matrix immediately before the picture tube employed to produce the third colour difference signal from the other two. Alternatively, the matrix circuit may be arranged to produce chrominance output signals corresponding either to the E<SP>1</SP>Q and E<SP>1</SP> I  signals of the NTSC specification or signal E<SP>1</SP>x, E<SP>1</SP> z , where E<SP>1</SP> x  = - 2.25 (E<SP>1</SP>R - E<SP>1</SP>y) - 9.385(E<SP>1</SP>B - E<SP>1</SP>y) and E<SP>1</SP> z  = - 0.583 (E<SP>1</SP>z - E y )- 2.25 (E<SP>1</SP> B  - E<SP>1</SP> y ) or any other set of signals corresponding to a suitable set of axes.

Abstract: 1393895 Silver salt material containing a dihydropyridine AGFA-GEVAERT 7 July 1972 [20 July 1971] 34045/71 Heading G2C A photo-sensitive material comprising a photodeactivatable reductor capable of reducing a silver soap at elevated temperature is imagewise exposed, and then uniformly heated while being in intimate contact with a sheet material comprising a reducible non-light-sensitive silver salt and 1,4- dihydropyridine of the formula:- where R 1  is H or 1-5C alkyl; each of R 2  and R 5  is H or alkyl; each of R 3  and R4 is CN or a substituent containing a carbonyl group directly linked to the 1, 4-dihydropyridine ring; and R 6  is H, alkyl or aryl, thereby transferring non- deactivated reductor to the sheet material and forming with the aid of the 1, 4-dihydropyridine a visible image thereon. The sheet material may be uniformly heated at 50-200C. The photosensitive material may contain a further reducing agent together with a catalytic amount of photolytically reducible silver halide formed from the non-light-sensitive silver salt and being in catalytic proximity with the silver salt in which case also the 1, 4-dihydropyridine acts as an auxiliary reducing agent, but this material after imagewise exposure is simply uniformly heated to produce a visible image. The non-light-sensitive silver salt may be a silver salt of an aliphatic carboxylic acid containing at least 14C, e.g. silver behenate or stearate. The photo-deactivatable reductor may be 4-methoxy-1-naphthol or 2-(pchlorophenyl)-acetoacetonitrile (see Example 1). The silver metal images obtained using the 1, 4- dihydropyridine as auxiliary reducing agent have improved colour density.

Abstract: 921,651. Grinding moving-machine cutters. D. DAUNTON. (R. Philippe). Oct. 10, 1959, No. 34425/59. Class 60. A grinding machine for sharpening toothed mowing machine blades or like cutters comprises clamping means 30 for a cutter 14 having its teeth engaged by a grinding wheel 1 mounted for rotation in a support 2 swingable about a spindle 8, rotation of which causes rotation of the grinding wheel, the spindle being spaced away from the rotational centre of the wheel 1 and serving also to rotate a cam 10 which is carried by the support 2 at a distance from the spindle 8 and which contacts a roller or the like 12 whereby rotation of the spindle serves both to rotate the grinding wheel and cause oscillating movement of the support and the wheel 1 by the reaction of the cam against the roller so that the grinding wheel moves along the teeth. The grinding wheel may be power driven or manually rotated through a crank handle 11 from the spindle 8 by gears carried by shafts 1-7 and the spindle itself, the casing 2 being pivotally mounted on supports 9 to provide for oscillatory motion about the axis of the spindle 8. The cam 10 is of truncated conical form and is drivingly mounted on an intermediate gear shaft 6. The roller 12 is supported by a forked threaded member 18 attached to the machine base 13. The member 18 is adjustable vertically in an arm 21 of a member which may be moved by a hand wheel 20 to swing in a horizontal plane about its point of attachment to the base 13, whereby the roller 12 may be moved along inclined face of the cam 10 to impart a larger or smaller oscillatory movement to the grinding wheel. The cutter 14 may be mounted to slide laterally with a support 29 to which it is secured by the clamp 30, the whole being rockable about a shaft 24. The shaft 3 on which the grinding wheel is mounted may be extended beyond the casing 2 to carry an additional, cylindrical, grinding wheel 26 suitable for grinding other forms of tools, the oscillatory motion being eliminated, when this wheel is in use, by swing- ing the roller 12 out of contact with the cam 10.
