Title: Electric motor with means for minimising axial vibration
IPC: H02K21/38
Filed: 1973-12-27
Abstract: 1459429 Electric motors TOKAI RIKA DENKI SEISAKUSHO KK 27 Dec 1973 [26 Dec 1972 9 March 1973 (2)] 59753/73 Heading H2A In a motor comprising an annular permanent magnet stator, an annular exciting coil coaxial with the stator, and a rotor having pole teeth extending from a circular body portion lying in a radial plane, the number of poles on the stator is an even multiple of the number of teeth on the rotor, and the flux paths in the motor are arranged so that the rotor experiences a continuous magnetic force in one axial direction. In the motor shown, the circular body portion of a rotor 5 is spaced an axial distance g 4  from a radially polarized cylindrical permanent magnet stator 4, and teeth 5a of the rotor 5 are spaced a radial distance g 3  from the stator 4, and also an axial distance g 2  from a casing yoke part 1 to which the stator 4 is fixed. Flux paths around an annular exciting coil 8 are completed by a further yoke part 7, the latter having an axially projecting portion 7a which provides flux linkage with the rotor 5 via a radial gap g 1 . The magnetic forces developed in operation are such that the rotor 5 is continuously biased towards the stator 4. In the motor of Fig. 5 (not shown), the rotor (5) has a magnetic plate (5b) which extends over a casing part (7), flux being able to pass between the plate and the casing part via an axial gap (g 1 ). In a similar arrangement (Fig. 6, not shown), a corresponding rotor plate (5c) and casing part (7) have axial projections (5<SP>1</SP>c and 7b). In the motor of Fig. 9 (not shown), the pole teeth (5a) of the rotor (5) are co-planar with the circular body portion of the rotor, and a planar permanent magnet stator (4) is co-planar with a projection (11a) of a yoke (11) having an E- shape section, a casing (10) being of non-magnetic material. In the arrangement of Fig. 10 (not shown), two motor units are mounted in tandem in two compartments of a partitioned casing, one unit being similar to that of Fig. 1 and one to that of Fig. 5.

Title: Coated recording member
IPC: G03G16/00
Filed: 1971-12-23
Abstract: 1380057 Vacuum vapour deposition XEROX CORP 23 Dec 1971 [28 Dec 1970] 59876/71 Heading C7F A flexible conductive layer is formed on the surface of an electric field deformable elastomer layer by vacuum evaporating a first conductive material and condensing it on said elastomer layer, and vacuum evaporating a second conductive material of lower melting point than said first material and condensing it over said elastomer layer coated with any material previously coated thereon. In the production of electro-photographic recording means, a substrate, if not conductive, is provided with a conductive layer, the latter being transparent if the former is also, and the body is coated with a photo-conductive layer which is itself coated with an elastomer which is deformable in response to an electrostatic charge image on the photo-conductor layer; the elastomer is then vapour-coated as above with a thin conductor layer flexible enough to "follow" deformations of the elastomer; if this layer is opaque then the substrate should be transparent. The preferred high- and low-melting materials are Au and In, and preferably 50 to several thousand  of Au is deposited first followed by a similar thickness of In before "mud cracking" appears in the Au; simultaneous deposition may also be used. Other high-melting metals are Al, Ag; Mg, Cu, Co, Fe, Cr, and Ni and low-melting metals are Ga, Cd, Hg, and Pb. The thin conductive layer may be coated with an optional transparent oil layer.

In use, the safety disc 23 is initially locked in position by a claw 26 on a washer 27, the washer having tongues sliding in grooves 29a, 29b in the support 4 to allow the washer to be depressed by the rim 20 of the plug to disengage the claw during the insertion of the plug pins 9 into apertures in the disc 23, allowing the disc to rotate with the plug through 37¢ degrees to align the pins and sockets prior to the final insertion movement. The disc 23 is retained by the head of the earth contact 6 about which it rotates and is provided with six shrouded cavities such as 25a, 25b in its perimeter, one of these being broken through at the time of installation by the locking claw 26 to allow reinstallation in only one possible position after dismantling. When all four sockets 1, 2, 3, N are in use the final position of the disc 23 relative to the support 4 is as shown in Figs. 2 and 3, the claw 26 being initially locked in the cavity 25a, while anticlockwise rotation of the initial position of the disc 23 through α, 90 or 180+α, 90 + α, 180 or 270 degrees allows the use of sockets 1 and 2; N and 1; N, 1 and 2; 1, 2 and 3 or N, 2 and 3 respectively. The socket carries a hinged cap 11 which can be locked in the closed position by a latch 13 when the plug is removed.

Title: Printing apparatus utilising a continuous moving transfer band
IPC: G06K15/14
Filed: 1968-12-19
Abstract: 1,241,610. Selective printing; printing surfaces. INTERNATIONAL STANDARD ELECTRIC CORP. 19 Dec., 1968 [22 Dec., 1967], No. 60327/68. Heading B6F. In a selective printer, a temporary magnetic liquid ink pattern is projected across an air gap on to a moving transfer band and retained thereon by magnetic attraction, whereafter the pattern is projected across another air gap, from the band on to a transversely movable record surface. In (Fig. 1) the pattern of magnetic ink droplets is projected on to the band (11) by a row of nozzles (14, Fig. 2), and the band is fabricated of a suitable material to form a permanent flexible magnet with north and south poles located on the opposite flat sides of the band. In an alternative embodiment, Fig. 3, the ink droplets are projected on to the band 31 by stationary station 33 comprising a row of ink nozzles (36, Fig. 4). The patterns so formed then pass beneath a stationary image magnetization station which polarizes each droplet on the band creating a magnetic diepole. After leaving the magnetization station, placement of a permanent magnet behind the image side of the band will cause the magnetic particles in the droplets to be attracted to the band thereby maintaining the image clarity until removal is effected on to the copy surface 43. The patterns are transferred magnetically or electrostatically on to the copy surface 43 in a similar manner to that described in Specification 1,238,210.

Abstract: Rescue apparatus for boats or the like, which become damaged at sea or spring a leak, comprises a buoyancy device (10) formed by a number of inflatable floats (11 to 14) connected to each other by means of a resilient back wall (16), and which in use, are attachable outboard of the boat's hull where they extend in a longitudinal direction. The back wall (16), which consists of a resilient, rubberized artificial-fibre cloth, is mounted in case of necessity around the boat's hull (34) by means of resilient ropes (20 to 23) or the like, the stern thereby remaining partly free. The device (10) is thus held in close proximity to the hull so that any leak in the hull is sealed by the wall (16) and the buoyancy of the boat is at the same time effectively enhanced by the floats. The apparatus can be used in order to maintain the manoeuvrability of the boat for as long as possible in dangerous situations. <IMAGE>
