Title: Automatic thread testing machine
IPC: G01N3/08
Filed: 1953-04-22
Abstract: 725,731. Testing physical qualities of materials. INSTITUT TEXTILE DE FRANCE. April 22, 1963, No. 11081/53. Class 106 (2). A machine for the continuous testing of threads comprises at least two assemblies 1, 2, 3 and 8, 9, 10 disposed one above the other, and scraper means 14, 15, 16 and guide baffles 55 so arranged that when a breakage of the thread 56 occurs, the end of the thread to be tested is guided to the lower assembly 8, 9, 10 which carries it along anew in such a manner as to attain an automatic and continuous operation of the machine. Means are also provided for measuring a physical magnitude such as the tension in or the elongation of the thread. As shown, belts 4 and 11 are spring tensioned around the rollers 2, 3 and 9, 10 respectively, the thread 56 passing between these belts and the corresponding rollers 1 and 8. The thread 56 is maintained under constant tension by causing the lower roller 8 to rotate at a slightly greater speed than the roller 1. A pivoted arm 33 is lightly biased against the thread 56 by a weight 36. If the thread 56 breaks, the weight 35 causes an extension 36 of the arm 33 to bridge two contacts 40, 41 to electrically advance by one unit a counter 37. The scrapers 14, 15, the arm 33 and the baffle 55 ensure that the broken end of the thread 56 is eventually caught between the belt 11 and the roller 8. The thread 56 is thus automatically re-tensioned and the extension 36 of the arm 33 lifted from the contacts 40, 41. Counting means for determining the length of thread dealt with and recording means for marking the distribution of breakages over the length of the thread tested may also be incorporated. The rollers 1 and 8 can be actuated separately by variable speed motors. Preferably, however, they derive their rotation from a motor 18, Fig. 2, through a variable speed gear 19 differentiating between the speeds of rotation of the rollers 1 and 8 to produce the desired tension in the thread 56. As shown, a coneshaped member 42 is driven at the speed of the upper roller 1 and a threaded spindle 44 parallel to a generatrix of the cone 42 is driven at the speed of the lower roller 8. A roller 43 threaded on the spindle 44 bears against the surface of the cone 42. In operation the roller 43 assumes progressively its position of equilibrium and indicates the stretch given to the thread 56 according to the difference in speed between the rollers 1 and 8. The tension in the thread may be tested by spring means 30 screw actuated to exert an adjustable pull through a pulley 21 mounted cantilever fashion on a bar 20 suspended on two links 22, 23 as shown. The tension in the spring is adjusted until the links 22 and 23 are vertical, the tension being indicated on a scale 32 by a finger 31. The thread 56 is normally disengaged from the pulley 21.

Title: Improvements in or relating to the manufacture of acetylene
IPC: C07C2/76
Filed: 1935-06-11
Abstract: Acetylene is made by heating a mixture of methane and hydrogen to above 1000 DEG  C. for a period between 0,1 and 0,005 second. At reaction temperatures up to 1300 DEG  C. and above 1500 DEG  C., the proportion of hydrogen in the mixture may be any proportion between 75 and 90 per cent, while at reaction temperatures between 1300 DEG C. and 1500 DEG  C. the maximum permissible proportion of hydrogen varies regularly from 90 per cent at 1500 DEG  C. to 80 per cent at 1300 DEG  C.  The products should be rapidly cooled and this may be effected, at least in part, by heat-exchange with fresh gas mixture. Acetylene may be recovered from the products by means of a solvent such as acetone, and the residual methane may be returned to the reaction or otherwise utilized.  The process may be effected in tubes of refractory material, such as silica or carborundum, or in apparatus comprising refractory tubes arranged to form annular reaction spaces, as described in Specification 440,432, or in refractory tubes having solid cores.  Various methods of heating the tubes are indicated.  An example is given in which a mixture containing methane 20 and hydrogen 80 per cent is passed through a silica tube heated to 1500 DEG  C.

Title: Improvements in or relating to devices for cathodic protection and the prevention and removal of incrustation
IPC: B08B9/049
Filed: 1959-04-02
Abstract: 865,083. Preventing corrosion and incrustation. SPECTOR, D. April 2, 1959 [Oct. 31, 1958], No. 11315/59. Class 123 (1) [Also in Group XXVIII] A device for cathodically protecting pipes, boilers, tanks, ships' hulls and other metal structures in contact with corroding liquids from corrosion and for electrolytically preventing scale formation on such structures consists of a cylindrical housing 3 closed by caps 5, 6 of insulating material and containing a direct current generator 15 having a commutator 16, the armature of the generator being mounted on a shaft 10 which passes out of the housing through a gland 14 in the cap 6 and carries at its end a propeller 11. The positive pole of the generator is connected at 19 to an anode of an inert material such as graphite or platinumcoated copper mounted in the casing 3 so as to be exposed to the liquid flowing through a pipe 1 in which the device is placed, whilst the negative pole is connected through a cable 21 to a roller 71 which bears on the said surface. Two rollers 7 mounted on arms 13 hold the device coaxially within the pipe, one of these rollers being driven through a gear train 8, 81, 811, 9 from the propeller shaft so that, in operation, with the propeller being turned by the liquid flow through the pipe, the device advances therealong whilst generating sufficient current to protect the pipe from corrosion and to prevent scale deposition thereon. In a modification, when the pipe is carrying oil, part of the current generated may be passed through a heating coil carried by the device to melt wax deposits, moreover the shaft 10 may be extended beyond the propeller to carry pipe scrapers or knives for the mechanical removal bf internal deposits. When used for the protection of ships' hulls the device 27 without the rollers 7 is towed behind the ship 26, Fig. 3, by a cable 28. Alternatively, Figs. 4 and 5, not shown, two devices are towed by cables or secured by fixed arms one on each side of the ship.

Patent GB-888287-A (GB)
Title: Constant level mechanism for carburetors and hydraulic apparatus
IPC: F02M1/00
Filed: 1960-03-31
Abstract: 888,287. Carburetters. SELDON, G. E. March 31, 1960, No. 11323/60. Class 7(3). [Also in Group XVIII] A device for maintaining a constant head of liquid at an orifice 11 which, as shown, is the jet of an I.C. engine carburetter, comprises a fuel reservoir in the form of a pan 1 having one part 8 which is wide and shallow with its floor 6 higher than the floor 7 of a narrower part 9. The pan is pivotally mounted in bearings 4 by pins 3 which project horizontally from the pan between its parts 8, 9. A fuel outlet pipe leads from the pan to the jet 11 which is disposed in the throat 18 of the carburetter Venturi. The pan is supplied with fuel through a pipe 12, the inlet flow being controlled by a valve 14 the stem 16 of which is in contact with the floor 6. When the pan is empty it balances in such a position that the valve 15 is lifted slightly to allow fuel to enter the pan. The fuel flows into the deep part 9 causing the pan to tip so that the valve is opened further. When the fuel reaches and overflows on to the floor 6 the weight of liquid in the wide, shallow part 8 increases more rapidly than in the narrow part 9 so that the pan tips back, gradually closing the valve 15. The valve finally closes when the head "h" between the level in the pan and the jet 11 reaches a predetermined value. At this point the pan is balanced. In a modification the part 9 of the pan is covered to form this part into a chamber which becomes completely filled before the predetermined head is reached.

Title: Improvements in or relating to demodulators for frequency modulated waves
IPC: H03D3/00
Filed: 1963-03-22
Abstract: 960,807. Frequency detectors. G. BATTAIL, and P. BRASSARD. March 22, 1963 [April 9, 1962], No. 11394/63. Heading H3A. In a demodulator for frequencymodulated waves, the signal to be demodulated is fed in parallel to a delay network and to an analyser which produces an estimate of the modulation signal; the estimate is used to frequency modulate a local oscillator, of which the output is fed to a mixer where it is mixed with the delayed signal; the difference signal from the mixer is demodulated and fed to an adding circuit; and the estimate is also fed to the adding circuit, the output of which is the demodulated signal. In Fig. 2 the input signal at terminal 101 passes to an estimating network 30 and to a delay circuit 20 having the same delay time as that of network 30. The network 30 comprises a spectral analysis circuit 33 which produces a D.C. output proportional to the instantaneous frequency, a low-pass filter 34, and a local oscillator 35 which is frequency modulated by the output of filter 34. The local oscillator output and the delayed signal are fed to a mixer 43, the output of which passes through a band-pass filter 45, which has a bandwidth about twice the frequency band of the modulation signal, to a discriminator 46 and an adding circuit 49. An output from the local oscillator is fed through a filter 47 and discriminator 48 to another input of adding circuit 49, the output of which is the demodulated signal. In a modification, Fig. 6 (not shown), the second input to circuit 49 is taken direct from filter 34 through a correcting circuit which introduces a delay and corrects the amplitude of the signals by amplification or attenuation. In further modifications, Figs. 7 and 8 (not shown), for use when the local oscillator frequency is the same as the signal carrier frequency, a phase correcting circuit is included to maintain the local oscillator in phase with the output of delay circuit 20. The spectral analyser 33 may comprise a plurality of tuned circuits connected in parallel and having mutually spaced resonant frequencies. The outputs of the tuned circuits are rectified and may be fed to a logic circuit which determines the rank of the tuned circuit with the largest output and energizes an appropriate D.C. generating circuit, Fig. 3 (not shown). Alternatively, the rectified outputs may be weighted according to rank and the weighted outputs added to give the output signal, Fig. 5 (not shown).

Title: Improvements in or relating to wired electrical insulating carrier plates and methods of producing the same
IPC: H05K7/08
Filed: 1960-03-31
Abstract: 907,630. Electrical wiring arrangements. SIEMENS & HALSKE A.G. March 31, 1960 [April 10, 1959], No. 11403/60. Class 37. [Also in Group XXII] A wired electrical insulating carrier plate has the electrical wiring anchored in position by positioning the wires on one side of the carrier plate to overlie apertures in the latter and placing clamping elements on the wires also in alignment with the apertures and then driving in the clamping elements so that a portion of the wire is drawn into the apertures under tension. Anchoring discs 1 shaped as shown in Fig. 1 are punched by means of plunger 5 from a metal strip 6, Fig. 5C, and the plunger 5 in the further course of its stroke moves the disc 1 into engagement with the wire 2 overlying the apertures in the insulating carrier plate 3 on support 4. Further movement of the plunger 5 forces the disc 1 and the corresponding portion of the wire 2 into the anchoring aperture; a counter pressure being exerted by a pin 16 so that the arched surface of the disc, caused by the pressure of the plunger 5, is urged into planar form thus causing the disc to expand radially and be securely anchored in the aperture as shown in Fig. 2a. Circuit components such as resistors 8, Fig. 6, are disposed on the side of the carrier plate which faces away from the wiring and their terminal conductors 9 are passed through holes in the carrier plate so as to cross the anchored wire 2 at an acute angle, Fig. 7 (not shown); the components thus being fixed sufficiently in position for subsequent dip or surge-soldering processes. If the holes for the terminal conductors do not lie directly beneath the anchored wiring the terminal conductors 9 are extended to the anchored wiring, Fig. 8 (not shown).

Abstract: 843,531. Coating with nickel. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 15, 1957 [April 14, 1956], No. 11438/56. Class 82(2) An object is coated with nickel by being subjected at elevated temperature to an atmosphere containing nickel carbonyl vapour, the pressure of said atmosphere being maintained below 10 mm. of mercury. Object 64 is supported on thermocouple elements 65 in bell-jar 60 and is initially de-gassed by being inductively heated to 250‹-1000‹C. by coil 63 while the pressure in said bell-jar is below 10-<SP>2</SP> mm. of mercury, said low pressure being produced by oil diffusion pump 80 and backing pump 94. The object is then allowed to cool to the temperature at which nickel deposition is to take place, e.g. 225‹C., pumps 80, 94 are switched off, and nickel carbonyl and, if desired, diluent gas such as argon or carbon dioxide are admitted to bell-jar 60 from container 2 and gasholder 24 respectively. The pressure in the bell-jar during deposition is maintained by pump 59, preferably at 1-3 mm. of mercury. The direction of vapour flow in the bell-jar may be reversed during a coating operation by manipulation of valves 40-43 which admit vapour to the bell-jar either through side-tube 61 or into the bottom of the jar via pipe 45. Object 64 may be of copper or uranium and may be subjected to a subsequent heat-treatment in situ. Residual oxygen and nitrogen in the belljar may be eliminated by heating another object in the bell-jar under conditions (quicker rise in temperature due to being closer to the inducton coil 63) such that it is oxidized and nitrided in preference to object 64. According to the Provisional Specification, the pressure of the nickel carbonyl atmosphere is maintained below 100 mm. of mercury.
