Patent GB-1055451-A (GB)
Title: Improvements in or relating to processes for electro-depositing a magnetic layer
IPC: C25D3/56
Filed: 1964-05-04
Abstract: A layer of magnetic Ni/Fe alloy is deposited on a conductor e.g. Cu wire using a plating bath containing Ni, Fe, boric acid and saccharine acid i.e. the un-neutralized sulphonamide.  The bath has sufficient boric and saccharine acid to maintain pH below 3 without the addition of mineral acid.  The copper wire is pre-treated by mechanical polishing, immersion in formic acid as chemical etch-polish, cleaned electrolytically using cyanide, soda, phosphate bath, neutralized with Hcl, and then plated.  The bath may also include lauryl sulphate.  Preferably the wire during plating is connected with a hysteresis cycle trace, and tested at intervals until the desired characteristic is attained.

Title: Improved filter press
IPC: B30B9/12
Filed: 1921-07-07
Abstract: 188,362. Plauson's (Parent Co.), Ltd., (Plauson, H.). July 7,1921. Extrusion presses. - In a continuous filterpress of the type described in Specification 155,834, the worm 4 is surrounded by a cylindrical filter element built up of superimposed annular members 1 separated by reinforcing plates 2 which project inwardly beyond the surface of the annular filter members. The filter-cake may be washed by supplying water to the worm, which would in this case be made hollow and furnished with outlet orifices, or alternatively, one or more hollow annular flanges 18 with water inlet pipes 17 may be employed. The unfiltered material is supplied through a pipe 6 at the top of the apparatus, the filtrate and wash-liquor are led away by a pipe 7 at the base of the outer casing 3, or the filtrate may be removed separately by a pipe 19 above the washing device. The solid matter escapes through a cone 8, at the bottom of the press, which is periodically opened by a camwheel 14 to an extent depending on the pressure of the filter-cake, the amount of opening being controlled by a spring 11. Brushes may be attached spirally to the upper part of the worm: spindle.
Patent GB-1471509-A (GB)
Title: Method and apparatus for forming material having a predefined cross-section
IPC: B29C48/08
Filed: 1975-05-02
Abstract: 1471509 Controlling calendered width AMF Inc 2 May 1975 [28 Aug 1974] 18396/75 Heading B5A [Also in Division G3] The width of elastomeric material extruded at 6 and formed between rotating dies 1a, 1b is controlled by adjusting the speed of the dies in response to an electrical signal corresponding to width. The material is in the form of narrow ribbon for tyre manufacture. The thickness is constant and depends on die spacing; width would vary due to changes in mass flow of the material and adjusting the die speed compensates for this. The dies are driven by an hydraulic motor 8a from a pump 8b driven by an electric motor 9 which also drives the extruder screw 4. The speed of the pump relative to that of the motor 9 is adjusted by a stepping motor driven by digital signals derived in an unspecified way from a comparison of the output of a scanning array of photo-diodes 10 with a reference. Control is effected on the average of ten scans to suppress the effect of noise. The die rollers are at different temperatures so that the material adheres to one, 1b from which it stripped by a powered stripping roller 7.

Title: Improvements in and relating to an apparatus for testing the strength of fabrics and materials in sheets or strips
IPC: G01N3/08
Filed: 1959-06-01
Abstract: 866,174. Testing strength of fabrics. TREITEMENTS CHIMIQUES DES TEXTILES. June 1, 1959 [June 2, 1958], No. 18543/59. Class 106 (2). Fabrics, paper and other sheet materials are tested for strength by gripping the fabric between two hollow jaws 9, 10 of a gripping device 2, 3 and allowing a stylus 14 to descend on to the fabric within the jaws under the control of a dashpot 23, the force exerted by the stylus being regulated by an adjustable weight 21. Jaw 9 is rigidly attached to member 2, and jaw 10 is pivotally mounted in a fork positioned at the end of branch 3 thus permitting close contact of the jaws which are provided with central apertures 12, the facing surfaces of the jaws being provided with serrations 13 to grip firmly the material under test. After the material has been inserted and gripped between the jaws, a blocking lever 32 is released allowing the piston of a dashpot 23 to descend, thus ensuring that the same force is applied by stylus 14 to the material under test for any given position of the weight 21 on a graduated arm 19 which is connected to the stylus 14 at pivot 18 and to member 2 at pivot 20. By setting the weight 21 at a position slightly below that which would result in perforation of material of normal strength, damaging of such material is avoided.

In a modification, the discs may be conical with apices upwards, and they may increase in size, Fig. 3, towards the top, the perforations also becoming larger. A concentric casing open at the top may surround the tube 2, the annular chamber thus formed communicating with a source of hot air or gas.

Title: Improvements in radio telegraphy and telephony
IPC: H04L27/04
Filed: 1923-07-30
Abstract: 225,592. Round, H. J., Eckersley, T. L., and Wright, G. M. July 30, 1923. Signalling by reversing phase of oscillations at each break; thermionic generators and homodyne receivers. - The phase of the oscillations in a transmitting aerial is reversed at the end of each signal or marking interval, either without change of amplitude for less than the signal interval or with decreased amplitude. The transmitter is preferably idle during word and letter spaces. With such a system of transmission the damping of the receiver may be reduced, and the duration of the reversed phase depends on the receiver damping and is arranged to bring the oscillation in the receiver down to zero between the elements of a signal. In the case in which the damping of the receiver cannot be made small, a homodyne of correct phase and amplitude mav be added at the receiver. A mathematical analysis is given showing that only half the power and size of aerial is required to obtain the same amplitude of received signals as with the ordinary method of sending. The rate of change of the received current may be ascertained by placing in the plate circuit of the rectifier a transformer the secondary of which is connected to a valve the plate current of which actuates a recording instrument. The Figure shows a shielded master oscillator 1, a resistance amplifier 2, and an amplifier 3. The output of the latter is coupled to the main amplifier by two pairs of coupling coils 4, 4<1> and 5, 5<1> arranged in opposition and connected to the main amplifier through a key 6. Adjustment of the coupling between the coils 4, 4<1> and 5, 5<1> enables the amplitude of the spacing relatively to the marking current to be adjusted. A transmitter for sending signals with a reduced period of reversed phase between the elements is also described comprising a perforated strip punched on one side with slots for dots and dashes and on the other side with triangular spacing slots. Two sets of contacts representing the two phases are made through the strip, and the contact for the spacing wave is adjustable so as to come opposite a longer or shorter portion of the triangular slots.

Title: Improvements in constant frequency wave source
IPC: H03B5/30
Filed: 1928-07-05
Abstract: 298,975. Electrical Research Products, Inc., (Assignees of Marrison, W. A.). Oct. 18, 1927, [Convention date]. Vacuum or Low-pressure apparatus, arrangements of.-Relates to means for compensating for the effect of circuit variations upon the frequency of a normally-constant frequencysource comprising a thermionic oscillator backcoupled through a tuning fork or similar mechanically-vibrating system. As shown in the Figure, an electromagnet 11 in the grid circuit of a valve 13 is impulsed by the vibrating leg of the fork 10, which is sustained in vibration by an electromagnet 12 energized by the resulting amplified plate current. The grid of the valve 15 is impulsed in parallel and the corresponding output current is fed to a load circuit 16. Biassing resistances 19, 20 maintain the output of the valve 13 constant, irrespective of fluctuations in the supply of filament current. A regulating winding 22, fed in series with a variable resistance 23 from the high-tension battery 18 compensates for any fluctuations in the voltage of that battery by decreasing the effective stiffness of the fork should the voltage fall and so lessen the power supplied to the driving-magnet 12, and vice-versa. Any increase in frequency due to a falling amplitude of swing is thus offset by the natural tendency to a diminution of frequency following upon a reduction in the effective stiffness of the fork.
