Title: Coil forming and transfer apparatus
IPC: B21C47/14
Filed: 1971-07-07
Abstract: 1345019 Coiling wire MORGAN CONSTRUCTION CO 7 July 1971 [9 July 1970] 31837/71 Heading B3C [Also in Division D1] A coil forming and transfer apparatus comprises an enclosure B into which product rings are delivered to accumulate therein into a cylindrical coil, a plate 58 in the enclosure for supporting the coil being formed; a mandrel 36 protruding upwardly through the plate into the enclosure, a side opening in the enclosure, and operating means for axially and pivotally manipulating the mandrel to transfer a fully formed coil through the side opening on to a coil transport device 30. In operation non-concentric rings 24 fall from a conveyer 26 around the mandrel on to a base comprising a platform 60 and the plate 58, Fig. 3, the platform and plate being lowered as the coil builds up. When the coil is fully formed retainers are moved into position to prevent further rings from falling around the mandrel. The platform 60 is lowered to below the upper end of casing 32 so that the plate 58 rests on stops 138. The mandrel is then lowered to a point where it will clear the retainers 136 where it is pivoted about the pivot P by a piston and cylinder 120. The pivot P is offset from the mandrel axis so that, when pivoting occurs, the plate 58 will be lifted off the platform 60 thereby preventing sliding of the coil on the platform. The mandrel 36 and plate 58 are pivoted into a slot 31 of the device 30 and then lowered into casing 32 so as to deposit the coil on base 30b of the device 30. The casing, mandrel and plate are then pivoted back to a vertical position and the cycle repeated. The mandrel can be vibrated, so as to compact the rings, by shaking the casing 32.

Title: Method of and apparatus for maintaining constant the specific mass  of a gas flowing in a conduit
IPC: G01N9/18
Filed: 1970-07-01
Abstract: 1310179 Measuring specific gravity COMPAGNIE DES COMPTEURS; 1 July 1970 [1 July 1969] 31845/70 Heading G1S [Also in Division G3] The specific mass of a gas flowing in a conduit 1 is maintained constant by comparing the specific mass with a reference value and utilizing the result to adjust a regulator 23. Gas from the conduit circulates through a pipe 4 upstream of a restrictor 18 into a chamber 2 which communicates with the conduit 1 by way of a filter 3 and contains a hollow glass ball 8. The ball is responsive to changes in specific mass and is connected by a force balance 6, a magnet 13 and a beam 12 with a device 15 providing a fluidpressure signal corresponding to the deviation of the specific mass from a desined value. A P+I amplifier causes the signal to operate a pneumatic valve 23. Alternatively, the chemical composition of the gas may be adjusted. Thermal insulation 19 is applied to the conduit 1, the pipe 4 and the chamber 2. Specifications 1228087 and 1174294 are referred to.

Title: Apparatus for detecting and correcting malfunction of a standard, reference electrode
Inventor: CONGER NORMAN LEE
IPC: C23F13/04
Filed: 1962-08-20
Abstract: In a system for protecting a metallic vessel 10 containing corrosive fluid from corrosion, by anodic polarization, apparatus for detecting <PICT:0977135/C6-C7/1> malfunction of a standard reference electrode 32 of the system comprises a second reference electrode 34 and means for comparing the potential differences between the reference electrodes and the vessel and for giving an alarm signal when the deviation between the compared potential difference exceeds a pre-determined value. In Fig. 2 the electrodes 32, 34 are connected to a device 30 which includes a mechanical vibrator which alternately places the electrodes in circuit with the vessel 10 so that when a deviation occurs an output voltage of square wave form results.  The device 30 converts this output voltage to alternating current which passes via a capacitor 39 to an amplifier 36.  The amplified A.C. is converted in a convertor 40 and supplied to a signal device 42. An electronic chopper circuit may be used instead of the mechanical vibrator. In an alternative arrangement, Fig. 3 (not shown), the electrodes and the vessel are connected to a bridge circuit which produces an output when the potential differences differ.  Fig. 4 (not shown) illustrates an arrangement in which a timing motor periodically connects the second reference electrode to the detecting apparatus at such times as no anodic current is being passed between the vessel 10 and the inert electrode of the system which includes an "on-off" controller for controlling the anodic current.  Fig. 5 (not shown) illustrates an arrangement in which the system includes a proportional controller continuously controlling the magnitude of the anodic current.  This arrangement also includes a timing motor for periodically connecting the second reference electrode.

Title: Improvements in or relating to installations comprising a gasfilled electric discharge lamp
IPC: H05B41/392
Filed: 1932-11-11
Abstract: 397,716. Discharge lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 11, 1932, No. 31941. Convention date, Nov. 12, 1931. [Class 39 (i).] A gas-filled lamp having a negative characteristic and supplied with current which assumes a zero value periodically, is connected in series with a gas-filled discharge tube having a grid to which is applied a potential which becomes negative at or before the period that the discharge current is zero, and does not become zero or positive until some time after the moment that the anode becomes positive with respect to its cathode ; by varying the period of time between the moment at which the current becomes zero and the moment at which the grid potential becomes zero or positive, the average current intensity through the lamp may be regulated. As shown in Fig. 1, the lamp 1 is in series with the tube 7, the anode 6 of, which is connected with one lamp electrode 2, the other 3 being connected through the secondary 12 of a transformer with the tube cathode 5. The A.C. supply 8 is also connected with a transformer primary 16 through an inductance 15 in parallel with a variable resistance 14, the secondary 18 being connected across the grid 7 and cathode through a resistance 19. Fig. 2 shows curves of supply potential 20, the potential 21 of the grid, and the current 22 through the tube and lamp ; the current 22 passes only during a fraction of each positive half wave of the supply, and the fraction, and thus the average current intensity, can be varied by varying the lag of the grid voltage 21 by means of the resistance 14 and inductance 15. Similar circuits are shown for a lamp having two anodes. With a D.C. supply the circuit may be opened periodically by a switch and the grid potential controlled by a switch.

Title: Incandescence bodies and methods of making the same for use as filaments of incandescent electric lamps and for other purposes
IPC: H01K3/02
Filed: 1933-11-16
Abstract: 427,757. Electric incandescent lamp filaments. SAKAKURA, Y., 62, Mukoyama Machi, Shibuya Ku, Tokio. Nov. 16, 1933, No. 31997. Convention date, May 19. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 6, 1934.] [Class 39 (ii)] In making bodies adapted to be heated to incandescence, such as rods, ribbons, or wires to be used as electric incandescent lamp filaments, a shaped body such as a slug formed from a powder of refractory metal, for example tungsten, is first caused to absorb substances which are capable of becoming materials for obstructing grain growth, or for augmenting thermionic activity, or modifying the physical properties of the metals by rendering them easier for mechanical treatment through alloying with one another, and then the surfaces of the shaped bodies are washed or steeped in water to remove the absorbed substances at or near the surface. The slug is subsequently sintered and subjected to mechanical treatment in known manner. In an example a slug of pressed tungsten powder is sprayed with a fairly concentrated solution of thorium nitrate, or the solution is applied by wrapping the slug in a soaked cloth, or with a brush, after which the thorium nitrate is removed from the surface layers by washing or " soaking out in distilled water. By repeating the soaking, washing, and drying processes a condition can be attained wherein there is little or no thorium nitrate at or near the surface of the slug and more -towards the core, or there may be little or none at or near the surface and core with a rich intermediate zone. The doped slug is dried in air at a temperature of about 200‹ C., and then baked in an electric furnace at 800 to 1200‹ C., in hydrogen. Other materials that may be used for obstructing grain growth are tantalum pentoxide, beryllium oxide, erbium oxide, indium sesquioxide, strontium oxide, magnesium oxide &c. Thus the pressed slug may be caused to absorb liquid beryllium nitrate, or may be heated in contact with powdered beryllium nitrate. After absorbing one kind of liquid the slug may be caused to absorb another kind, the absorbed liquids being subsequently diluted by washing.

Patent GB-654953-A (GB)
Title: Improvements in apparatus for the assembly of indirectly-heated cathodes
IPC: H01J9/06
Filed: 1948-12-13
Abstract: 654,953. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. Dec. 13, 1948, No. 32222. Convention date, Feb. 20. [Class 39 (i)] A method of assembling indirectly-heated cathodes comprises simultaneously compacting a bundle of heater wire, producing oscillatory motion of the bundle relatively to a cathode sleeve about their common axis, moving the foremost end of the bundle relatively to the sleeve in a small orbit, and moving the bundle and sleeve towards one another to cause the bundle to enter the sleeve. A portion of the apparatus for carrying out this method is shown in Fig. 8 and comprises jaws 58 which grip the end of the cathode sleeve S, the sleeves being supplied by a conveyer (not shown). The jaws 58 are then thrust forwards to bring the free end of the sleeve into a fixed funnel-shaped sleeve support 96. The bundle of heater wire F is supplied to and gripped by a chuck 122, which advances along a straight-line path to initially insert the free end of the bundle into a guide member 188, which has a passage 192 slightly smaller in diameter than the internal diameter of the sleeve S, so as to compact the bundle of heater wire. As the chuck 122 is advancing, it is oscillated about its axis through a comparatively small angle so that if the cathode sleeve is of the lock-seam type as shown in Fig. 11, any portion of the bundle which may abut the seam is displaced for unobstructed admission into the sleeve. To assist this action and to render the action of compacting the bundle easier, the guide member 188 is vibrated rapidly in such a manner that its central axis moves transversely in an orbital circle, the diameter of which is small in relation to that of the sleeve and is related to the difference between the diameter of the sleeve and bore 192. After the chuck 122 has completed its longitudinal motion and has inserted the end of the heater F into the sleeve S, the insertion may be completed by the application of a short blast of compressed air to the end of the heater through passages (not shown) in the chuck 122. As the chuck 122 and jaws 58 are retracted to their initial positions for the start of the next operation, the jaws 58 are opened to release the completed cathode, which is removed by a further conveyer (not shown).' The complete machine is described in detail in the Specification.

Title: Thyristor rectifier having a device for self-ignition or recovery protection
IPC: H02M7/155
Filed: 1973-07-09
Abstract: 1430009 Controlling converters ALLMANNA SVENSKA ELEKTRISKA AB 9 July 1973 [10 July 1972] 32507/73 Heading H2F In a converter comprising a plurality of series-connected thyristors 13 ... In, each thyristor is provided with a device 12 for indicating when the forward voltage reaches predetermined limits, the signals from all the thyristors 13 ... In being combined and fed to a counter 5 which emits a signal for turning on all the thyristors 13 ... In if an insufficient number has regained their blocking ability. This prevents breakdown of thyristors due to the rising anode/cathode voltage being distributed over too few thyristors in their blocking condition. As described, a control pulse generator energizes light-emitting diodes 21 coupled via light guides 22 to photodiodes 11 in the individual control devices 1 for the respective thyristors. The anode voltage of the respective thyristors is monitored and a light signal emitted from a light-emitting diode 12 via further light guides 20 when the respective anode voltage reaches a predetermined value. The signals are picked up by photodiodes 2 and fed to a memory 10 the output of which is counted by a threshold device 5 which feeds an enabling signal to an AND gate 7 when the number of thyristors 13...In which has regained their blocking ability is less than n x , but inhibits the AND gate 7 when n x  is reached. The AND gate 7 is also enabled by a pulse from a monostable circuit 4 which commences at a time t o  after the first pulse from any diode 12. Time t o  is dertemined by the expected rate of rise of anode voltage across the series-connected thyristors 13 ... 1n. If the inhibiting signal from counter 5 precedes the pulse from monostable circuit 4, then the AND gate 7 provides no output and the pulse generator 9 is operated normally from the control system 23. If, on the other hand, an insufficient number of thyristors have regained their blocking ability, at the time t o , the AND gate 7 supplies an extra pulse to the generator 9 which turns on all the thyristors 13 ... 1n. In Figs. 2 and 3 (not shown) the monostable circuit 4 is dispensed with and the actual value of the anode/cathode voltage is monitored by means of a potential divider across the whole series chain.
