Patent GB-1096729-A (GB)
Title: Method of manufacturing magnetic data storage device
IPC: H01F10/06
Filed: 1966-06-01
Abstract: A magnetic data storage device is made by depositing on a non-magnetic substrate a first layer of a non-magnetic catalytically active metal such as non-magnetic nickel, palladium, aluminium or copper activated with palladium, then chemically depositing a second layer of magnetic material and alternately repeating the deposition of the first and second layer materials to the required coating thickness.  The magnetic material is preferably cobalt but it may also be nickel, cobalt-nickel, cobalt-nickel-iron, or nickel-iron alloys. The substrates are brass or polyethylene terphthalate and the magnetic layers are all of the same thickness.  The cobalt and nickel are deposited from hypophosphite solutions with a pH of 8.2, the palladium from palladium chloride solutions, the copper from formaldehyde complexed copper solutions.  The polyethylene terephthalate substrate is first catalyzed with stannous chloride and palladium chloride, and the brass substrate is first treated with palladium chloride alone or palladium chloride and stannous chloride.

Abstract: 853,856. Dobby. BRITISH COTTON RESEARCH ASSOCIATION. July 28, 1958 [Aug. 1, 1957], No. 24367/57. Class 142(2). In a positive double-lift open shed dobby, Fig. 2, fixed bars 21, 22 receive the upper ends 19c of any hooks 19 whose lower ends 19b are not engaged with the lifting knives 17, 18; accidental displacement of the hooks on the bars is prevented by lowering locking bars 28, 29 to the positions 28a, 29a, the bar 29 being of comblike construction to pass between the jacks 12. The hooks are set by feelers 23, 24, of which the pair pertaining to the same baulk 11 are coupled together by a spring 25 which holds them against stops 26, 27 when they are not rocked by pegs 30 on a pattern barrel 16; the pegs on alternate lags 31 are staggered so that the feelers 23 are operated for one pick and the feelers 24 for the next. Pattern mechanism, Fig. 3. The pattern barrel 16 is driven by a pin 35 engaging an arcuate slot 36 in the striker wheel 34 of a Geneva motion 37, 38; when the dobby is reversed, the slot 36 provides the necessary re-timing between the operation of the feelers and the dwell of the lifting knives. A clutch 39 between the Geneva wheel 38 and the shaft 16a of the pattern barrel enables the barrel to be turned by hand, the Geneva wheel then riding out of the notches of the clutch against the action of a spring 40. For pick-finding, the pattern barrel is turned an even number of notches of the clutch. To bring all the warp threads to the same level, the barrel is turned only one notch; the feelers 23, 24, Fig. 2, are then operated when the corresponding hooks 19 are out of their range whereby, on turning the loom two revolutions of the crankshaft all the hooks become engaged by the knives 17, 18 and all the heald shafts are consequently lowered.  Adjusting shed size, Fig. 1. The dobby is mounted at the side of the loom and coupled to the shafts 15 by links 13, 13x and bellcrank levers 14, 14x. The lower ends of the jacks 12 have three holes 12b to receive the links 13; the holes lie on an arc of a circle having its centre at the position occupied by the right-hand end of the links 13 when the shafts are in their lowermost position; when the shed opening is altered by moving a link 13 from one hole to another, the bottom shed line therefore remains unaltered at shuttle race level. Specification 733,777 is referred to.

Abstract: 1,062,194. Analogue-to-digital converters. INSTITUTE AUTOMATIKI I ELECTROMETRII SIBIRSKOGO OTDELENIJA AKADEMII NAUK U.S.S.R. June 12, 1964, No. 24455/64. Heading G4H. [Also in Division H4] In a self-balancing digital voltmeter for an A.C. voltage of any waveform, a balancing voltage is derived from the unknown voltage which has the same waveform as the unknown voltage and has a known r.m.s. value, being adjusted so that it has the same energy as a reference D.C. voltage, the balancing voltage being fed through a digital attenuator which is adjusted until it balances the unknown voltage, the setting of the attenuator being displayed to indicate the value of the unknown voltage. The A.C. voltage U x , Fig. 1 (not shown), to be measured is of arbitary waveform and is fed to shaper 1 which produces a reference voltage U r  and having a similar waveform to the input voltage U x  but being constant while U x  varies over a given range. The reference voltage is fed to the balance voltage generator 2 to produce a level-quantized balancing voltage in antiphase to the input voltage. These are compared at 3 and the result is used at 4 to control the voltage generator 2 to reduce the difference. The result of the measurement is displayed in a digital form at 5. The circuit 1 comprises a wide-band pre-amplifier with automatic gain control in series with an amplifier having an automatic gain circuit which includes a lamp and photo-varistor, the lamp being supplied alternately with a D.C. reference voltage and the output of the amplifier, the automatic gain being controlled by the output from the varistor to make the r.m.s. value of the A.C. output equal to the D.C. reference voltage. This A.C. reference voltage having the same waveform as the unknown input voltage and the same r.m.s. value as the known D.C. reference voltage is applied to an attenuator 2 and the attenuated signal U k  applied to comparator 3 for comparison with the input. The comparator comprises a transformer 134, Fig. 4 (not shown), receiving the two signals at its ends. The output from the secondary is amplified and applied to the phase detectors the outputs of which set a relay if one is larger and not if the other is larger. The attenuator comprises a resistor network, Fig. 3 (not shown), connected by relay contacts to earth or the A.C. reference voltage U r . The total resistance of the network remains substantially constant. The relays are controlled by corresponding flip-flops 153-164, Fig. 5 (not shown), each of which is switched on in turn by a pulse distributor 148. If the resulting increase in voltage U k  overbalances the input U x  the corresponding flip-flop stage is switched off again. The final conditions of the flip-flops is recoded at 177 and indicated in decimal form at 5.

A vehicle exterior rear view mirror comprises a base 12, having resilient arms 13 extending upwardly therefrom, and a member 18 connecting said arms to a head 23, the upper ends of said arms being urged towards each other and defining an aperture 15 adapted to receive a corresponding shaped spigot of said member 18, the arrangement being such that rotation of said head will cause the spigot to rotate in aperture 15 forcing the arms apart, but on release of the head the resilience of the arms will cause the head to return to its original position, or 180 degrees with respect thereto if the rotation is greater than 90 degrees. The end of member 18 remote from the spigot is formed with a ball 22 received in a socket 28 of a member 25.

The part of member 25 forming the recess 28 comprises four axial fingers having rotatable thereabout a sleeve 31. Posts 32 of said sleeve co-operate with ramp surfaces forming the base of a groove 27, rotation of the sleeve causing the fingers to grip the ball. The mirror parts may be formed from moulded synthetic resin and the reflective surface of the head formed by chromium plating a specular surface.

Charts and diagrams.-Relates to a meteorological instrument or indicator for producing and comparing radial diagrams representing centrelines of magnetic stress upon the surface of the earth, as based on the angular relations between the earth and other members of the solar system, calculated in reference to the plane of the ecliptic for specific dates from tables of right ascension and declination. The instrument comprises a number of index pointers 10 lettered to designate the sun, moon, and larger planets and rotatable independently over a graduated base 1 and beneath upper and lower rotatable plates 14, 11 adapted to receive diagram sheets. The lower plate 11 is provided with an index pointer 12 and with a clamping-screw 20 for securing it in adjusted position. The pointers 10 are mounted on centre washers 7 and between spacing-washers 8 on a central bolt 3 on the base 1. The plate 11 is mounted on a centre washer 13 on the bolt 3, and a plate 14 is fitted on the upper end of the jolt and spaced clear of the plate 11 by the washer 13. The washers 7, 8, 13 are held stationary by bolts 16. The diagram sheet placed on the upper plate 14 is clamped by means of a nut and washer 19 on the bolt 3, and the projecting end 6 of the bolt serves as a centre for a straight-edge for ruling radial lines on this sheet.
