Title: Improvements in nozzle assembly for electric arc spray apparatus
IPC: B05B7/22
Filed: 1959-12-29
Abstract: 881,672. Spraying fusible materials. GENERAL ELECTRIC CO. Dec. 29, 1959 [Dec. 31, 1958], No. 44090/59. Class 69 (3). Electric arc spraying apparatus comprises a nozzle electrode 12 and a guide electrode 16 providing opposed surfaces 12c, 16a between which an arc is established, and the material to be sprayed from the orifice 14 of the electrode 12 is fed in the form of a rod 30 through the electrode 16 into the arc, and is sprayed by gas or vapour under pressure supplied to the space 17 between the electrodes via a tube 17a. A baffle plate 20c uniformly distributes the gas &c. to the space. The electrodes are adjustably connected to the main body 20 to which coolant is supplied through a tube 20a. The nozzle 12, provided with a coolant passage 26, has a surface 12b diverging from the orifice 14 to meet a flat surface 12a at right angles to the nozzle axis; it is alleged that such an arrangement prevents ambient air from being drawn inwards towards the orifice and the spray stream. In a modification the electrode 12 is in two parts and includes a removable insert provided with the surfaces 12a, 12b and 12c; the rod is pushed into contact with the guide electrode by a spring-urged ball bearing. The electrode 12 may have cooling fins.

Title: Demodulator circuit for colour television signals
IPC: H04N9/70
Filed: 1975-11-04
Abstract: 1531248 Television receivers INDESIT-INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 4 Nov 1975 [8 Nov 1974] 45736/75 Addition to 1499990 Heading H4F A colour killer is responsive to the output of a phase comparator fed with the two sub-carrier demodulating signals that are passed to respective demodulators for demodulation of a chroma signal, the colour killer serving to allow or prevent the passage of the chroma signal to the demodulators. The chroma signal is of the swinging burst PAL type. The chroma signal 1 passes via colour killer 2 to demodulators 8, 9. Burst gate 3 enabled by a line frequency signal 12 passed the burst via half-line frequency switch 14 to synchronize oscillators 17, 18. One oscillator provides a sub-carrier in phase with the PAL line bursts and the other a sub-carrier in phase with the NTSC line bursts. Switches 15, 16 which are synchronized with switch 14 ensure that demodulator 8 always receives a subcarrier having the phase of the burst in the line now being received and that demodulator 9 always receives a subcarrier having the phase of the burst in the preceding line. Both sub-carriers are also fed to a phase comparator 22, one being subject to a +90 degree shift at 21. During reception of the chroma signal the inputs to the comparator are alternately in phase and in anti-phase so the comparator output is a signal at half-line frequency. This signal passes via a half-line frequency filter 23 to a threshold unit 24 which maintains the colour killer 2 inoperative. In the absence of bursts neither oscillator 17, 18 oscillates, so the comparator output is zero and the colour killer is energized. Should a spurious burst-frequency signal be received during monochrome transmission both oscillators will oscillate with the same phase and the inputs to the comparator will therefore be in phase quadrature so that again the comparator output will be zero and the colour killer will be energized.

Title: Cap feeding apparatus
IPC: B65G47/14
Filed: 1972-10-05
Abstract: 1384152 Feeding aerosol caps from irregular assemblage in a hopper to regular flow in a shoot; pneumatic conveying PNEUMATIC SCALE CORP 5 Oct 1972 46062/72 Headings BSA and B8S Aerosol caps (not shown) having a cylindrical body portion from which a reduced diameter stem coaxially extends, are deposited in a heap in a hopper 12 which is mounted at an inclination to the horizontal. The caps fall into cylindrical recesses 108 which are formed around the periphery of a member 14, which is mounted for continuous rotation in the hopper 12. The caps are carried round and upwards, and those which are not located stem upwards in respective recesses, 108 are blown back into the heap by air jets 128, 140, (Fig. 4) and 138 (Fig. 7), or are deflected into the heap by the action of members 130, 148, 152, and 160 (Fig. 2). A cam ring 112 acts on followers 120 which are respectively slidably mounted in the recesses 108. By this means the caps are lifted progressively upwards, and eventually out from the recesses 108. A deflecting member 150, a member 154 (see also Fig. 9), a member 158, and members 159 and 160 act in succession on the caps to turn them over into a position in which the axis of each cap lies radially relative to the direction of rotation with the stem pointing inwards. The caps are now conveyed onwards by the action of an air jet 166 (Fig. 10) carried by a bracket 168 (Fig. 2) and enter between members 182 and 188 (Fig. 13A) which form the beginning of a discharge path 162. The cross-section of this path is shown in Fig. 14, the body of the cap being disposed between guide rails 178 and 184 and the stem between rails 180 and 186. The stem rests on a turned over portion 192 of the rail 186. The caps are projected into the path 162 by the action of air jets 207 (Fig. 13A), 213 (Fig. 13C) and 215 (Fig. 13D). The caps are projected onwards along the path 162 by air jets issuing from a conduit 204 (Fig. 14). A gap is formed in the members 184 and 188 so that any caps which have their stems missing, are pushed out of the stream through the gap by the action of a spring (216) (Fig. 15, not shown). The caps remaining in the path 162 are turned through a right angle by the action of a helical guide section (218). If the hopper is loaded with too many caps, they deflect a member 224 (Fig. 2) which operates to switch off the drive of the member 14. A photo electric device 220 (Fig. 13A) also operates to shut off the machine if it detects an absence of regular flow of the caps.

Abstract: 1,108,609. Tuned interconnectors for A.C. power networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 18 Oct., 1966 [1 Nov., 1965], No. 46177/65. Heading H2H. In a tuned interconnecting arrangement for two A.C. networks of the type in which a seriesresonant L.C. combination 3, 4 is detuned at a predetermined current by saturation of a reactor 5, the unsaturated impedance of the reactor 5 is chosen so that during normal operation a small portion of the total coupling current passes through the reactor and the main portion traverses the capacitor 4. For the best coupling and current-limiting effects, while at the same time safeguarding the capacitor against undesirable voltage rise, the unsaturated impedance of the reactor 5 should be between 1À25 and 5 times the impedance of the capacitor 4 and it is stated that in many cases the optimum of this ratio is about 2. Also the saturated impedance of the reactor 5 should be between one fifth and one fiftieth of the unsaturated value, a ratio of one twentieth being stated to produce optimum effects. To enable standard reactors to be used irrespective of the characteristics of the interconnected networks, the reactor 5 may be connected in series with an inductance or capacitance (6), Fig. 2 (not shown), whose impedance is between 0À25 and 2 times the saturated impedance of the reactor 5. A resistor (7) may be connected across portions of the members 3, 4, Fig. 3 (not shown), or portions of the members 3, 5, Fig. 4 (not shown), this resistor providing damping to reduce voltage swings and being connected to ensure negligible power loss at normal operation. The resistor may be in series or parallel with a capacitance or a linear or non-linear inductance which influences the power factor during the increasedimpedance period following detuning of the interconnector.
