Abstract: 937,642. Magnetic recording &c. heads, supporting. NORTH AMERICAN AVIATION Inc. July 15, 1960 [Aug. 3, 1959], No. 24708/60. Class 40 (2). Data storage apparatus comprises a disc having magnetizable media on both sides and rotatably mounted on a shaft extending between two headplates, each of said headplates having at least one magnetic head disposed therein. As described, an aluminium disc 1 is rotatably mounted on a shaft 5, the clearance between bearing surfaces 3, 4 on the disc and shaft forming an air bearing. The disc 1 is rotated by an electric motor comprising a stator 7 and rotor rings 6 on the disc 1 and has magnetizable annular surfaces 8, 9 adapted to co-operate with recording heads 13-16 on headplates 11, 12. The gaps between the disc 1 and the plates 11, 12 are adapted to form air thrust bearings and the plates 11, 12 are secured to the shaft 5 by flexible diaphragms 20, 21. The plates 11, 12 are provided with troughs 26 and grooves 35, Fig. 2, the grooves 35 extending beyond the circumference of the faces 8, 9 of the disc 1 so as to allow air to be drawn into the bearing area. The troughs 26 may be of uniform depth or may have stepped surfaces (Figs. 3, 4, not shown). Fig. 7 shows a read head comprising a high permeability polepiece 52 of three laminations, the opposite limbs 53, 54 of the polepiece being held between sections 56, 57 of ferrite material having a hollow centre 58 filled with a plastic dielectric material such as an epoxy resin mixed with aluminium oxide powder, this material providing rigidity. The write head (Fig. 6, not shown), is of similar construction. The electric circuit for the write head may comprise a centre-tapped coil the ends of which are connected to driver tubes (Fig. 8, not shown). In the read head, one end of the coil is earthed and the other end is connected to the grid of a detector tube (Fig. 9, not shown). Specification 929,878 is referred to.

Abstract: 1,061,155. Control of two A.C. motors. INSTITUT FœR FÍRDERTECHNIK LEIPZIG. June 15, 1964, No. 24721/64. Heading H2J. The closing-line and hoisting-line of a grab winch are driven respectively by induction motors 1, 6, having wound rotors, the motor 1 having two sets of rotor resistors 2, 4. When both motors have been accelerated nearly to synchronous speed, relay 9 is closed to interconnect the rotor circuits, and relays 3, 5, 8, are opened. This allows an open grab to be lowered at super-synchronous speed, with both motors operating at the same speed so that no partial closing of the grab occurs while it is being lowered. The maximum speed is restricted by closing relay 5 to introduce the rotor resistors 2, 4. The relay 5 may be operated by a device responsive to speed or rotor voltage, or by a timing relay.

Title: Improvements in methods of distillation
IPC: C02F1/04
Filed: 1958-08-08
Abstract: In distilling liquids in an apparatus of the kind wherein the liquid to be distilled is spread in a thin layer over a surface of a heat-conducting vapour barrier by means of one or more movable wipers which are repeatedly swept across that surface while heat is applied to the opposite side of the barrier to evaporate the liquid, the speed of movement of the wipers and the resilient force urging them against the vapour barrier are correlated so that almost complete evaporation of the liquid occurs between successive wipings. Preferably the vapours produced are compressed and condensed on the opposite side of the vapour barrier so that no further heat is necessary to effect evaporation and no further cooling is necessary for condensation.  The film of distil <PICT:0856489/III/1> <PICT:0856489/III/2> p  <PICT:0856489/III/3> <PICT:0856489/III/4> <PICT:0856489/III/5> <PICT:0856489/III/6> land, when spread on a vertical surface, is also preferably so thin that there is substantially no flow under the influence of gravity.  In Fig. 1 the distilland, such as sea water, is supplied by pipe 9 to a rotating supply member 14 arranged to supply distilland in advance of the wipers 17 moving over the inside surface of cylinder 5 which forms the vapour barrier.  The supply member and the wipers are both driven by rotor 16.  Vapours leave by openings 22, are compressed by a compressor 21 and condensed on the outer surface of the cylinder 5. Excess distilland leaves by opening 24 and distillate by opening 25. A number of cylinders may be arranged in a single condensing chamber served by separate compressors or a communal compressor.  Drops of condensate forming on the outside of the cylinders may be dislodged by means of circular magnets 54 (Fig. 15) made to revolve by magnets 55 arranged on the rotor 16.  The outer magnets are supported by troughs 57 having holes 58.  Members 63 may also be provided to prevent condensate flowing over the magnets.  In an alternative arrangement, (Fig. 19), the vapour barriers are plane vertical members 124.  Distilland is sprayed on to the evaporating surfaces by sprays 104 and both the evaporating and condensing surfaces may be wiped by rotating vanes 122.  Several different types of wiper are illustrated including one made in several sections (Fig. 8), which more easily accommodates irregularities in the cylinder, one in which the vapour barrier is flexible and is distorted by the wipers (Fig. 11) and one incorporating its own distilland feed (Fig. 9).  The cylinder may be made of flexible material which is distorted by the wipers.  Film thicknesses may be up to 0.002 inch when distilling sea water.

The pick-up 12 also supplies current to a device 14 for moving the plates 2 and a device 15 for operating the gate 16. The device 14 has a spindle 17 provided with a projection 18 for engaging abutments 19 on the plates 2; in the open position of the plates 2 the projection 18 may be aligned with the side of the shoot 21. The device 15 is automatically controlled through a relay by the passage of the trains 6 which operate contacts 20. The shoot 21 has a semicircular opening in its front to facilitate an even discharge of material and to prevent jamming of the latter when the gate 16 is closed. A hinged mouthpiece 22 is provided on the shoot 21 and is biased to the closed position by a counterweight 24 when the gate 16 is closed. The trains 6 are preferably provided with magnets for operating the contacts 20 but, alternatively, a photo-electric beam may be interrupted by the trains to operate the contacts. Interlock means may be provided to ensure that the gating unit can only be moved when the plates 2 are closed. A plurality of aligned hoppers or bunkers may be served by one travelling gating unit and smaller hoppers or bunkers may be provided to receive excess material which runs from the main hoppers or bunkers before the plates 2 are closed. Alternatively, a gating unit may be provided for each hopper or bunker.
