Title: Apparatus for electrostatic spray coating
Inventor: KERR SIMONNE JUNE
IPC: B05B5/053
Filed: 1968-07-02
Abstract: 1,209,653. Coating apparatus; spray producers. AIR-O-STATIC Inc. 2 July, 1968, No. 31511/68. Headings B2F and B2L. Electrostatic spraying apparatus comprises a rotary head for centrifugally atomising and radially projecting coating material supplied thereto, electrode means located rearwardly of the atomiser head, and a high voltage source having one terminal connected to the electrode means and the opposite terminal connected to the atomiser head and to an article located forwardly of the atomiser head. The article and atomiser head are thereby maintained at the same potential and an electrostatic field is established between the electrode means and article, said field surrounding and being spaced radially from the atomiser head for receiving therein the atomised coating material. An insulating body 30 and a metallic tubular member 34 support an air motor rotating a metallic dished atomiser head 12. Member 34 is rigid with a metallic base 18 having an earthed connection G2. Compressed air is supplied to the motor via a pipe 20 and is discharged, together with compressed air supplied by a pipe 22 to the space between the motor and member 34, over the rear surface of head 12. Coating liquid, supplied via a pipe 24 and passages within member 34, is directed radially on to the front surface of head 12 near the axis thereof, and is discharged radially from the rim of lead 12 in finely atomised condition. The air passing over the rear surface of head 12 forms a shroud for the atomised liquid. Body 30 carries a circumferential row of charging electrodes 16, each of which is an insulating rod containing a metallic core terminating in a forwardly-directed point 100 located rearwardly of head 12. Said cores are connected via a cable 26 to the negative terminal of a high voltage generator 28, the positive terminal of which has an earth connection G1. The arrangement is thereby such that a primary field E and a secondary field F are respectively established between electrodes 16 and an article 14 having an earth connection G4 and between electrodes 16 and head 12. The droplets discharged from head 12 are initially positively charged and, after being carried through field F by their initial momentum, are negatively charged in field E by the ions emitted by the electrodes 16 and are thereby conveyed for deposition upon article 14. In a modification the electrodes have tubular metal cores which are connected to generator 28 and also convey compressed air to form a shroud for the atomised liquid particles.

Title: Improvements in draw-out electrical switchgear arrangements for duplicate bus-bar systems
IPC: H02B11/18
Filed: 1931-11-14
Abstract: 390,880. Switchgear structures. MARSTON, G. S., Garden Reach, Chalfont St. Giles, Buckinghamshire. Nov. 14, 1931, No. 31570. [Class 38 (v).] In a vertical draw-out switchgear structure for duplicate bus-bar systems, the circuitbreaker is arranged, after being lowered to isolate one set of bus-bars, to be rotated as a whole to a position in which, on raising, the isolating contacts corresponding to the alternative set of bus-bars are engaged. As shown in Figs. 1 and 2, the circuit-breaker d is suspended from a central screwed stem g on which, after being lowered for isolating purposes, the circuit-breaker may be rotated as a whole to a different angular position. In one angular position the isolating contacts carried by the circuit-breaker tank, which are arranged as shown in Fig. 2, are adapted to engage, when the circuit-breaker is raised, two sets of fixed isolating contacts, Fig. 3, secured within a fixed hood b, one set corresponding to one set of bus-bars a and the other set to a feeder c. In the other position the circuit-breaker isolating contacts are adapted to engage feeder contacts and also isolating contacts corresponding to the alternative set of bus-bars a<1>. To ensure the correct engagement of the isolating contacts the circuit-breaker carries guide rods f co-operating with guide slots e in the fixed structure which are provided in positions corresponding to the two working positions. The circuit-breaker is raised and lowered through bevel gears j, hand screw-and-nut mechanism. Where owing to lack of space it is impossible to arrange the sets of isolating contacts in linear formation they may be grouped differently.

Abstract: 406,093. Machinery guards. HAMILTON & SONS, Ltd., J., and HAMILTON, E., Pollard Street, Manchester. Nov. 10, 1932, No. 31711. [Class 80 (iv).] A guard, d, e vertically slidable in grooves in brackets c and comprising independent slidable rods p is adapted to be connected to a knife holder l by locking means which, when they engage a hole or notch k in the holder l, prevent the knife from descending. When the knife b reaches the bottom of its stroke a spring- pressed plunger i jumps into a longitudinal recess n. The plunger is carried by the upper bar d of the guard frame so that when the knife rises the guard is raised. On account of the lateral motion of the knife, at the top of the stroke the plunger jumps into the hole k and the knife cannot descend until the operator withdraws the plunger by means of the knob m. The rods p are vertically slidable in the horizontal part of a frame o. Those rods which meet the material q are arrested in their descent. In a further modified form of guard the rods are urged downward by springs in addition to gravity.

Abstract: 1,273,763. Production of refractory metal carbides. UNION CARBIDE CORP. 25 June, 1969 [26 June, 1968], No. 32012/69. Heading C1A. In a process for making refractory metal carbides, agglomerates such as briquettes made by compaction of the finely divided metal oxide and carbon, in an amount which is 100-110% by weight of the stoichiometric amount required to form the carbide, are accumulated into a moving bed moving through an extended heating zone at 1500-2100‹ C. so that CO is formed, in countercurrent to a stream of inert gas, e.g. argon, introduced at the downstream end of the heating zone, the inert gas being substantially uniformly distributed across the crosssection of the bed, said gas stream causing the partial pressure of CO at the upstream end of the heating zone to be substantially higher than at the downstream end, the bed being moved at such a rate that the final product contains 3% by weight or less of O 2 . The final product is then cooled to below 400‹ C. before being exposed to the atmosphere, in order to avoid re-oxidation. The partial pressures of CO are preferably more than 400 mons at the upstream region and not more than 150 mons in the downstream portion. In the Figure, the bed of agglomerates 3 is disposed in a vertical shaft 5 down which it moves at a predetermined rate, in countercurrent to a stream of inert gas introduced at 9. The reaction zone 11 is heated by heating coil 7, and gaseous products leave via 15. The movement of the bed is controlled by device 19.

Abstract: 164,300. Rheinische T³rschliesserfabrik Boge & Kasten. June 2, 1920, [Convention date]. Addition to 149,300. Locks, revolving-barrel.-In a door lock, the bolt or latch is operated by a revolving member journaled to the barrels of two cylinder locks, one on each side of the main lock, the member being engaged by the key of the cylinder locks. Fig. 1 shows the device applied to a mortise lock. The member m has a sleeve journaled to the pinlike extensions h and i of the barrels f, g of the cylinder locks and has a tongue k for operating the bolt. The key z positions the pin-tumblers to allow either barrel to revolve and also enters a groove n in the sleeve of the member m, coupling it to the barrel so that rotation of the key turns both the barrel and the member m, causing the tongue k to operate the bolt. The member is retained in the position in which the groove n is in line with the key-stop in the barrels by a catch r, and the barrels are held in their centred position by annular lips o, p fitted into grooves in the casing a, and are secured by a common screw d. The device may also be applied to a rim lock, in which case the sleeve of the member m is elongated as shown in Fig. 5 to allow the end of the key to reach it when the key is inserted into the cylinder lock on the outside of the door.
