Title: Data storage devices
IPC: G11B17/02
Filed: 1975-05-15
Abstract: 1460244 Flexible-disc data storage apparatus INTERNATIONAL BUSINESS MACHINES CORP 15 May 1975 [1 July 1974] 20478/75 Heading G5R  To access a selected disc in a data store comprising multiple flexible record discs 1, Fig. 1, mounted between and rotatable with an axially fixed end plate 5 and an axially movable end plate 11c, 11t, an accessing means (not shown) is operated to effect a first degree of separation, Fig. 7a, between two immediately adjacent discs 1 at a selected interface and then end plate 11c, 11t is moved away from plate 5 at a rate fast enough to cause suction action to move those discs 1 between said interface and plate 11c, 11t as a unit with the latter thereby widening the spacing between the two discs at said interface sufficiently to allow transducing on a selected disc thereat, Fig. 7d. The separation at Fig. 7a may be produced by contacting facing disc edges momentarily with a mechanical probe or by using an air jet. End plate 11c, 11t is moved away from plate 5 by a solenoid 11k and is returned by a solenoid (not shown) acting on link 11r or by a spring. Discs 1 are slidably mounted on pins 3 fixed to disc 5. Provision of off-centre holes 1b in discs 1 and of radially porous spacers 17 between discs allows circulation of air from hollow drive shaft 9, centrifugal action developing a negative pressure in the interdisc spaces when disc 11c, 11t is in its nearest position to disc 5. As the discs at the selected interface are separated to the position of Fig. 7a a positive pressure difference develops between the selected and expanded interface space and the other interdisc spaces. Suction and cohesion effects together with this pressure difference slide those discs 1 to the right of the selected interface as a unit upon actuation of solenoid, 11k, a membrane 11u normally covering holes 11w in disc 11c moving away from the latter during such movement to admit additional external air into a space 16, defined within the inner edges 16a of annular discs 1, to counteract a tendency of those discs to the left of the selected interface to be drawn towards the expanding interface. A disc 11t of the movable end plate may be rigid but is preferably flexible.

Filed: 1920-07-10
Abstract: 148,949. Latour, M. Dec. 16, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Inductances.-A magnetic controller for insertion in a wireless aerial or like circuit comprises an inductance having an iron core, the reactance of which is varied by mechanically modifying the air-gap, the operating means being a signalling key, a relay, or a rotating shaft. Reference is made to a method of signalling by varying the degree of saturation of the core by a low-frequency current or otherwise. According to the invention, the magnetic circuit is closed except for an air-gap formed with poles separated by slots. Between opposite poles moves an armature made up of parts which are alternately conductors and non-conductors of electricity. The former act as magnetic screens and decrease the reactance of the coil when they are in position between opposite poles. The armature may have the form of a plate with translatory motion, or of a disk with conducting sectors which revolves so as to give modulations of musical frequency. The apparatus may be immersed in oil for cooling purposes, and very fine iron wire may be used in its construction.

Title: Improvements in rolls for cane crushing apparatus
IPC: C13B10/06
Filed: 1920-07-16
Abstract: 167,074. Goold, L. W., (Fulton Iron Works Co.). July 16, 1920. Rollers or cylinders.-In a roll for cane-crushing apparatus having means to allow the roll to expand and contract relatively to its shaft, an intermediate portion of the roll is firmly secured to the shaft to prevent creepage of the roll on the shaft while an end portion or portions are movable relatively to the shaft to permit of expansion or contraction. As shown, one end of the roll A is recessed to receive an abutment collar D, preferably formed integral with the shaft B, and the other end is recessed to receive an abutment collar E removably secured to the shaft. Abutment shoulders 2 at the ends of the roll cooperate with the collars D, E and prevent or limit longitudinal creepage of the roll on the shaft. The shalt, which is forced into the roll by hydraulic pressure, has an elongated intermediate portion 3 and end portions 4, 5 which are secured by firm frictional engagement with corresponding openings in the roll. The portion 3 is larger than the end portion 4 and smaller than the end portion 5, so that the shaft can be inserted into one end of the roll until its collar D reaches the roll. The portions 3, 4, 5 of the shaft are primarily larger in diameter than the corresponding external diameters of the roll, and the excess in diameter of the portion 3 is greater than the excess in diameter of the other portions 4, 5 so that the intermediate portion of the roll is firmly secured to the shaft while the comparatively free end portions of the roll permit longitrudinal expansion and contraction. The removable collar E may consist of segmental sections 6 held in a groove 7 of the shaft by a ring 8 forced on to the shaft and into one end of the roll.

Title: Process for reducing the tendency of a fabric to produce pills
IPC: D06C11/00
Filed: 1955-07-26
Abstract: 786,868. Finishing fabrics. DU PONT DE NEMOURS & CO., E.I. July 26, 1955 [July 26, 1954], No. 21593/55. Class 42 (1). A process for reducing the tendency of a fabric, containing staple synthetic fibres, to produce pills, comprises effecting random flattening of the crosssectional dimensions of the fibres in the exposed crowns of the yarns of the fabric, and thereafter compressing the flattened fibres, at the points at which flattening has occurred, against adjacent fibres, whereby the flattened fibres are locked within the body of the fabric. Fibres may be randomly flattened by brushing the surface of the fabric gently with a rotary brush covered with card wire acting on the fabric as it passes between two guide rollers or as it passes over a stationary backing surface. The ends of the wires 1 are ground to present a toe 2 and a heel 4, the relative movement between the wires 1 and the fabric 5 being, as shown, such that the wires exert a heel-toe action. After brushing, the flattened fibres are locked within the body of the fabric by shrinking, e.g. by heating in an overfed pin tenter. Alternatively the fabric may be shrunk by a chemical treatment or by a combination of chemical and physical treatment.
