Title: Means for safeguarding the working of machines for breaking-up, opening or working cotton or other waste or textile material
IPC: D01B3/02
Filed: 1942-08-01
Abstract: 559,122. Magnetic separators. GREENWOOD, H. S. Aug. 1, 1942, No. 10818. [Class 72] In apparatus in which safeguarding means for use or in combination with machines for breaking up, opening or working cotton or other fibrous waste or textile material are provided so that ferrous metal &c. frequently found in such material may be removed and so the risk of fire or damage removed, the material is fed by the front part of a lattice between two lifting lattices b, c, into the upper of two inclined shoots 1, 2 arranged at an angle to each other and then into the lower shoot 2 the material being inverted or turned over' and so passed over permanent U-shaped magnets m mounted in the guide plates or walls of such shoots, the purified material passing on to the rear end of the lattice a which delivers it to a breaking roller d. A further set of magnets m may be disposed 'laterally over the lattice a to deal with any metal conveyed with the fibrous mass which is lifted by the lattices b, c. Specification 545,398 is referred to.

Title: Improvements in signalling systems
IPC: H02J13/00
Filed: 1923-04-23
Abstract: 222,164. Western Electric Co., Ltd., (Western Electric Co., Inc.). April 23, 1923. Indicators.-A supervisory and control system comprises a central and remote station connected by two conductors and means including said conductors for jointly operating a device at the remote, station and means including one of the conductors for signalling the central station. The figure shows a central station A and a remote station B having power switches 50, 51. The switch 50 carries a contact 52 engaging one or other of contacts 53,. 54 and has associated with it a pair of low resistance relays 58, 59 controlling the power switch solenoids 83, 89. Contact 52 is connected through the line 62 to a high resistance polarized relay 63 at the central station. Indicator lamps 65, 66 to show the position of the power switch are controlled by the relay 63. The operation is as follows : the operating of key 73 establishes a circuit from ground and conductor 62 through relay 59 to battery 78 and also short circuits relay 63 and energizes relay 75. The closure of contacts 81, 82 energizes the solenoid 83 and operates the switch 50 and the closure of contact 84 provides a holding circuit. The release of the key 73 de-energizes relay 59 and a signalling circuit is established through relay 63, line 62, contact 52, 54, winding of relay 58, con tact 86 and battery 78. In a modification non- marginal relays are used, instead of marginal release relays 58, 59, and a separate contact for each device connects an alternating current source to line to give the preparatory signals while the operation of the switches is effected by a master control contact common to all the devices. In this modification and in that illustrated an accidental ground will not operate the power switch.

Abstract: 436,531. Electric clocks. ETABLISSEMENTS E. JAEGER, 2, Rue Baudin, Levallois-Perret, Seine, France. April 12, 1934, No. 11068. Convention date, Feb. 26. [Class 139] In a clock driven by a synchronous motor wherein the driving mechanism is invisible, the drive is transmitted through an oscillating transparent plate so that the motor may rotate in either direction and, the usual means for determining its direction of rotation may be omitted. The motor which is preferably self-starting drives through its shaft 10, and helical or worm gearing 13, ..... 15, a shaft 16, an eccentric pin 17 on which rocks a bell-crank lever 18 a finger 21 on which oscillates the prismatic glass sheet 23 located between the front and back glass faces 1, 4 of the case. The face 1 constitutes the dial, and centrally of the rear face 4, a sleeve 24, Fig. 5, is rigidly held by a nut 25 and washers 26, 27. Oscillatably mounted on sleeve 24 is a bush 29 to which is secured the sheet 23 and a drum casing 33, 34.

Title: Magnetice device having domains
IPC: G11C11/14
Filed: 1974-03-13
Abstract: 1461604 Magnetic storage arrangements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 March 1974 [13 March 1973] 11173/74 Heading H3B Single wall domains propagated in a magnetic plate are transferred from one movement constraining path to another by a unidirectional magnetic field applied in the plane of the plate. In Fig. 1 two parallel movement constraining paths 2a, 2b along which domains 3 in a magnetic plate 1 are propagated by an in-plane rotating magnetic field are formed generally by T and I permalloy layers arranged in staggered relationship. Domain transfer from path 2a to to path 2b is effected in a zone 8 by a unidirectional magnetic field in the plane of the plate, this field when applied elongating a domain at the I bar in the zone and causing its transfer to an adjacent L bar. In a modification, Fig. 8, a domain 24 propagated in a path 12 stops at a permalloy rectangle 19. Further movement of the domain takes place by elongation transfer into either a continuation path 13 or an orthogonal path 19 only when an appropriately directed unidirectional field is applied in the plane of the domain supporting plate 11. An alternative embodiment, Fig. 9, uses angelfish permalloy layers forming paths 32, 33, 34. Domain propagation is effected by a varying magnetic field orthogonal to the domain-supporting plate 31, and a domain in path 32 stops at a permalloy rectangle 36 until a unidirectional in plane magnetic field elongates it to couple with either path 33 or path 34.
