Abstract: 394,760. Sheet-delivery apparatus; -tripping-arrangements. CREED, G. E., 122, Blackheath Hill, and GESTETNER, Ltd., D., Neo-Cyclostyle Works, Tottenham Hale, both in London. Feb. 27, 1932, No. 5959. [Classes 100 (i) and 100 (ii).] In a stripping-device for machines in which paper sheets pass between rollers and tend to adhere to one of the rollers or to a member travelling thereover and in which the other roller is a movable pressure roller, a grooved collar is provided at each end of the pressure roller, and a saddle member engaging each collar is provided with a finger adapted to engage the sheets, limiting-stops being provided on the saddle, which is also provided with means for ensuring that the fingers are raised into correct position by the motion of the pressure- :-roller carriage. The effect of the fingers is to arch the sheet laterally whereby its tendency to adhere to the roller &c. is restrained. As shown in a duplicator comprising a stencilcarrying band 20 passing over inking-cylinders 16, 16a, and comprising also a pressure roller 9 mounted in frame members 33 raised and lowered by arms 29 connected to links 28 reciprocated by cams 25 substantially as described in Specification 266,773, [Class 100 (ii), Printing processes &c.], each stripper comprises a finger 14 extending from a sheet-metal plate 13 having a saddle 7 adapted to rest on the spindle 8 of the roller 9, and depending legs 1, 10 engaging a groove 11 in a collar 12 on the spindle. In the lowered position of the roller 9, projections 2 on the legs 1 rest on a rod 4, and the fingers 14 are above the roller and bear on the upper surface of a sheet being fed into the machine. When the roller 9 is raised, a rod 6 on the roller carriage engages lugs 5 on the legs 1, and, after rising above the fingers, raises them to the position shown in which the sheet is pressed against the stencil : lugs 21 determine the upper positions of the fingers. The pressure roller may be exchanged to correspond with the width of sheet in use, the saddles being placed on the collars prior to inserting the roller in its carriage.

Title: Improvements in the manufacture of coloured filaments, yarns, films and similar materials having a basis of organic derivatives of cellulose
IPC: D01F2/28
Filed: 1937-02-27
Abstract: Artificial filaments, straws, tapes, films, and similar materials having a basis of organic derivatives of cellulose and containing colloidal silica are coloured by means of dyestuffs for which in the absence of the silica the materials have no affinity. The organic derivative of cellulose may be an acetate, formate, propionate or butyrate, or a methyl, ethyl, or benzyl ether.  The process is applicable to short or long fibres and to yarns, and fabrics of all kinds.  Mixed yarns and fabrics containing cotton or wool and cellulose derivative fibres may be dyed with a single dyestuff. Water in the silica gel to be used may be replaced by acetone, methyl alcohol, ethyl alcohol or other liquid.  The process results in dyed materials which may also have an increased scorching temperature, reduced lustre, and no distinct melting point.  In an example, sodium silicate is dissolved in six times its weight of water, the solution is cooled and phenol phthalein added.  Normal hydrochloric acid is added till the colour has almost disappeared and the solution gelatinizes.  The gel is heated, then broken up and washed with water until free from chloride.  The product is washed with absolute alcohol or acetone to replace the water in the gel.  The silica gel is incorporated in a solution of a cellulose derivative and the solution is extruded into an evaporative atmosphere or a coagulating bath to produce filaments or films.  The silica gel may be incorporated with cellulose acetate and the mixture formed into lacquer chips. These are mixed with acetone to form a solution which is extruded with production of filaments or films.  The material may be dyed with a cotton dyestuff such as cotton blue FFB or diamine fast blue FFB, or other azo dye.  Specifications 450,285 and 465,797 are referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of inorganic colloids other than colloidal silica. This subject-matter does not appear in the Specification as accepted.ALSO:Silica gel, for incorporation with cellulose derivative filaments or films, is obtained by cooling a solution of sodium silicate dissolved in six times its weight of water, adding phenol phthalein as indicator, and then adding normal hydrochloric acid until the colour almost disappears and the solution gelatinizes. The gel is heated, broken up, and washed with water until free from chloride.  The gel may then be washed with absolute alcohol or acetone so that this liquid may take the place of the water in the gel.

Title: Process for fabricating magnetic data storage devices
IPC: G11B5/64
Filed: 1963-02-14
Abstract: A process for making magnetic data-storage devices having a saturable magnetic coating deposited on to a non-magnetic substrate includes the step of peening the substrate prior to depositing the magnetic coating thereonto. A phosphor-bronze or beryllium copper drum pre-finished on a lathe is peened by a device rotated at high speed around the drum, being mounted, for example, on a lathe spindle and comprising hardened steel rollers rolling over cam surfaces to give about 200,000 blows per minute to the drum. The peening causes the grain structure of the drum surface to be circumferentially oriented therearound. The peened surface is then cleaned and subjected as a cathode to an electrolytic action in an aqueous solution containing 200 grams/litre cobalt chloride, 200 grams/litre nickel chloride, 25 grams/litre boric acid, .05 gram/litre sodium lauryl sulphate, and 6 grams/litre approximately one-third each by weight boric acid, para-toluene sulphonamide, and orthotoluene sulphonamide. The solution has a pH value of 4.5 and a temperature of 120 DEG F. Plating current density is 480 amps/sq. ft. followed by a 160 amps/sq. ft. deplating current at a 60 cycle/sec. repetition rate. A coating of 80-85% cobalt and 15-20% nickel is formed to a thickness of about 150 microinches and has a preferred direction of magnetization characteristic which is circumferentially oriented around the drum in the same direction as the translational movement of the peening action. The magnetic coating may also be peened. The coating may be formed by spraying vacuum evaporation or chemical deposition.

Title: Degaussing Circuit
Inventor: DUDDRIDGE GEOFFREY
IPC: H04N9/29
Filed: 1968-02-08
Abstract: 1,164,786. Cathode-ray tube circuits. STANDARD TELEPHONES & CABLES Ltd. 8 Feb., 1968, No. 6306/68. Heading H4T. [Also in Division H1] A degaussing circuit includes a degaussing coil connected in series with a bidirectionally conducting switch comprising at least one unidirectionally conducting device, the switch being set into its conducting condition to initiate a degaussing cycle. The invention is described in connection with the degaussing of a shadowmask colour television picture tube. In one embodiment the degaussing coil 6 (Fig. 1), which is suitably located on the tube, is connected in series with a switch 5 consisting of a thyristor 7 in parallel with an oppositely poled diode 8, the series arrangement being connected across a capacitor 4 which is charged via resistor 3 (30K) to a potential of about 30 volts derived from a suitable point in the television receiver. To initiate a degaussing cycle switch 5 is closed, by applying a suitable voltage to the gate of thyristor 7 so that coil 6 together with the associated resistance and capacitor 4 form an L.C. circuit producing a damped oscillatory wave the amplitude of which decreases to about 1% of the initial value after about 100 to 500 oscillations. In a second embodiment (Fig. 2) the circuit utilizes an A.C. supply, e.g. the mains supply to the receiver, connected at 11, 12 and the switch comprises a pair of parallel connected oppositely poled thyristors 14, 15. To initiate a degaussing cycle (by operation of switch 17) the gate 15 is supplied from a circuit 16 with a trigger pulse which is phase-time controlled such that the switch is turned-on at later-and-later instants in successive half-cycles of the A.C. current. Thus the current flowing in the degaussing coil 13 is progressively reduced to a minimum.
