Filed: 1968-05-21
Abstract: 1,154,300. Electro-physical measurementflows. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 21, 1968 [May 25, 1967], No. 24209/68. Heading G1N. An eddy-current flow detector for metal tubes comprises a pair of axially aligned coils 1, 2 through which the tube passes, each coil being connected in an identical Hartly oscillator circuits 4, 5, having their grid voltages monitored by a differential valve voltmeter 8, 9. Change in oscillator load due to a localized flow is reflected in a difference in oscillator grid voltages, whereas slow variations due to change in e.g. diameter or thickness produce substantially no difference signal. This effect can be emphasized by differentiating the voltmeter output signal. The spacing between the coils is arranged so that the coupling factor is just sufficient to maintain the oscillators in synchronism (frequencywise).

Title: A process for the treatment of contaminated copper
Inventor: WEBSTER SAMUEL JOHN
IPC: C22B15/00
Filed: 1951-10-19
Abstract: A process for removing lead contamination from copper comprises treating the copper, preferably at an elevated temperature, e.g. 60 DEG C., with an aqueous solution of copper acetate to convert the lead into lead acetate.  If all or part of the lead is in the form of lead oxide, the acetate solution should contain free acetic acid. When tin is also present, the copper is treated alternately with a solution of copper acetate and a solution of copper sulphate according to Specification 698,285.  The spent copper acetate solution may be regenerated by adding copper sulphate, allowing the so-formed lead sulphate to settle and decanting or treating in a centrifugal filter to remove the lead sulphate and any copper sludge, from which the metals themselves may be obtained by ordinary metallurgical methods.

Title: Improvements relating to electrical discharge devices for use as translating apparatus
IPC: H01J19/02
Filed: 1924-10-17
Abstract: 223,589. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Waterman, F. N.). Oct. 19, 1923, [Convention date]. Thermionic relays.-A tube for use as a translator comprises a source, of electrons, such as a. filament cathode, an anode, and a thermosensitive element, the temperature of which is raised by bombardment of the anode by electrons. As shown in Fig. 1 the thermo-sensitive element 4, which may consist of material such as cupric oxide having a negative resistance coefficient, is mounted between a cylindrical anode 3 wholly or partly surrounding the filament, and a cylinder 5, which is connected, through a lamp E or other indicator and the secondary 17 of a transformer with the anode. The filament is connected through a switch 9 with a tapping on the secondary 6 of a transformer which supplies the potential for the anode; or the switch may be connected at 12 between the anode and the transformer, or in the lead 7 common to both the filament and anode circuits. The bulb may be exhausted or contain a non-oxidizing gas. Normally the current from the secondary 17 is insufficient to light, the lamp E, but, when the switch 9 is closed, the anode is heated bv electron bombardment, and the resistance of the element 4 is reduced, with the result that the lamp is lighted. Several such cylindrical anodes and sensitive elements, each controlling a, separate lamp, may be mounted around a common filament; or the anodes and sensitive elements may be of segmental form. In a modification a grid electrode is interposed between the filament and anode, and is connected through a switch with the secondary of a transformer supplying the current for the filament and lamp, and the potential for anode. The grid potential may be positive or negative with respect to the filament so that the lamp is either lighted or extinguished when the switch is closed. In a further modification the passage of electrons to the anode is controlled by a magnetic field produced by a. winding mounted around the outer cylinder and connected through a switch with the secondary of a transformer.

Filed: 1973-05-23
Abstract: 1436721 Measuring roundness electrically RANK ORGANIZATION Ltd 22 May 1974 [23 May 1973] 24748/73 Heading G1N The irregularities of a part circular surface of a body are determined by a feeler gauge associated with the test surface whilst the body is rotated, the signals from the gauge being analyzed mathematically to eliminate the effect of non- coincidence between the axis of rotation and the centre of the part circular surface and to subtract the value of the nominal radius, thereby to obtain a magnified measurement of the surface irregularities. The mathematical analysis also determines the co-ordinates x, y of the axis of rotation of the test body relative to its true centre. The Specification defines an equation for the optimum reference curve for the test surface, derives the mathematical relationships between the angular end positions of the test piece and the displacement signals from the feeler gauge to produce the reference curve, and describes the apparatus necessary to establish these relationships and to determine the variations in radius of the test body surface relative to the reference curve and the values x, y representing the eccentricity of the test body centre.

Abstract: 757,163. Ignition systems. BENDIX AVIATION CORPORATION. Aug. 25, 1954 [Sept. 29, 1953], No. 24767/54. Class 7(4) [Also in Group XXXV] In an ignition system one end of the primary winding 5. Fig. 1, of a magneto is connected to the unearthed contact of a circuit breaker 7 which is adapted to open and close a circuit including the winding 5, a battery B and means including a current-limiting resistance 18 for connecting the other end of the winding 5 to the battery. During normal operation the common low potential ends of the magneto windings 5, 6 are earthed as shown, through spring-loaded contacts 19, the magneto being rendered inoperative by closing an ignition switch 17 which earths the other end of the primary winding 5. To effect starting a switch. 16 is closed to energize a coil 15 and close the associated spring-loaded contacts 12 whereby the battery B is connected to both the starter motor SM and to a second coil 20, energization of which operates the contacts 19 to break the earth connection of the magneto windings 5, 6; the latter are thereby connected to the battery through the 0.7-3 ohms current-limiting resistance 18 to supplement the energy of the magneto. The contacts 12 may be manually operated. In a modification, the switch 19, 20 is omitted and the windings earthed through the resistance and the starter-motor winding, and, optionally through a second resistance in parallel with the first. In another embodiment, the ignition-switch contacts 22, Fig. 3, are located between ihe windings 5, 6 and the contacts 19, the contacts 22 being actuated manually, as shown, upon energization of a coil 23 when a switch 24 is closed; such an arrangement of the ignition switch may be used with the previous modification. A battery other than that used for actuating the starter motor may be used to boost the magneto and the circuits may employ insulated instead of earth return.

Apparatus for producing circular metal bands to be formed into wheel rims comprises a band straightening machine 16 through which the strip from a coil 21 is fed by pinch rolls 23, 24 to a cutting machine 17 which severs the strip into separate bands which are fed individually to a machine 19, which bends the bands into circular form, from which they are transferred by a conveyer to a flash butt welding machine 11 and a weld upset stripping machine 12. After the strip has been severed the bands are preferably passed through a press 18 so that its ends can be bent by dies 25, 26 so that in the circular form the ends of the band are co-planar. The circular bands are transferred from the machine 19 by pushers which push the bands axially between a pair of arcuate grippers (33),Figs. 4 and 5 (not shown), mounted on a carrier 15 which is reciprocable by fluid pressure. Several carriers 15 are mounted on an endless conveyer 13 which moves step-bystep to present the band to the welding machine 11 and the stripping machine 12. The band is positioned on the carrier 15 by a guide member (35) which abuts the ends of the band, Fig. 5 (not shown). The grippers (33) engage the band from the machine 12 and the carriage 15 is withdrawn until it is adjacent the welding machine. The bands are held by clamps in the welding machine and the guide (35) withdrawn. After welding the bands are transferred to the stripping machine 12 where the weld upset is removed. The stripping machine 12 comprises a weld-upset stripping tool and may also have rotating wire brushes and coining rolls. When the tools are retracted the band is ejected down a shoot 36 to a wheel rim forming machine. In an alternative arrangement the circling machine has two heads (42), (43), Fig. 3 (not shown) and two welding machines (39), (41) and the conveyer indexes twice the spacing between the carriers 15.
