Patent GB-1281170-A (GB)
Title: Automatic visual indicator and transposing device for organ, electronic organ and pianoforte
Inventor: ATKINS WILLIAM ALBERT
IPC: G10H1/00
Filed: 1969-04-17
Abstract: 1281170 Note indicators KEY DEVELOPMENTS Ltd 22 Oct 1969 [17 April 1969] 19610/69 Heading G5X An indicator comprises a translucent panel on which the lines of the staff are marked and behind which indicator lamps are positioned (Fig. 2, not shown). The associated circuit, so far as concerns only the notes C to E, is as shown. A switch 59 energizes one of the bus-bars 51-57, each corresponding to a selected key, and causes key signature lamps such as 66, 67 to display sharps or flats in the required positions on the staff. Operation of notes of a keyboard closes switches 42-46 and, in the ease of the notes C, D, E for example, causes lamps 48-50 to indicate notes in the corresponding position in the lines and spaces of the staff, at least when the key of C is selected on the switch 59. If a key, say D or A, is selected which includes say C sharp in the signature the lamp 50 will be lit to indicate the note C by closing the switch 45 of the note C sharp. If the switch 46 of the note C is closed the lamp 50 will be lit and also a lamp 64 indicating an accidental natural. Other lamps 60-63 indicate accidental sharps, flats and naturals as appropriate to particular notes in particular selected keys. A switch 82 causes a relay 81 to be energized so that, when a key is selected having a signature of flats, the enharmonic note D sharp/E flat is displayed as E flat i.e. closure of the switch 43 lights the lamp 48 and the lamp 60 also if E flat does not appear in the key signature. In the keys having sharp signatures the relay 81 is normally de-energized and the same note is then displayed as D sharp, unless a switch 77 is closed when the key of C or G has been selected. The note is then displayed as E flat. The switch 77 enables the automatic selection of E flat or D sharp to be over-ridden in the case of a minor key, such as E minor, which has the same signature as a major key such as G major. The keyboard for operating the device may be the keyboard of an electrophonic instrument and either the visual indication or the sound output may be switched off.

Title: Method and apparatus for obtaining synthetic foam materials
IPC: B29C45/53
Filed: 1972-04-27
Abstract: 1379052 Transfer injection of foamed plastics material L STAERMAN 27 April 1972 19640/72 Heading B5A In order to fill the foaming/injection chamber 3 of a transfer injection apparatus unfoamed plastized material containing a foaming agent is fed from a plastizing chamber 1 through a movable transfer nozzle 4. The latter may be mounted on an injection piston 2 connected to the plasticizing chamber 1 so that the plasticized material can pass through the nozzle 4 as the piston 2 retracts. The chamber 1 contains a plasticizing screw 5 whose speed may be adjusted with respect to the retraction speed of the piston 2 to vary the density of the foam. The transfer nozzle 4 comprises a cylindrical crown 11 which is provided with circumferentially spaced outlets 12 and which communicates with the plasticizing chamber 1 via a duct 13 which can be closed by a spring-loaded ball 14 as the pressure in the chamber 1 falls and the chamber 3 fills. When the latter is full, the piston 2 and chamber 1 advances to inject the foamed material through a valved injection nozzle 9. Formation of the foam is assisted by the reduced pressure produced in the chamber 3 due to the retraction of the piston 2.

Filed: 1944-10-12
Abstract: 593,419. Linear - dimension gauges. JACK & HEINTZ RESEARCH CORPORATION. Oct. 12, 1944, No. 19705. Convention date, Sept. 6, 1943. [Class 106 (ii)] In a gauge for checking or measuring diameters of circular holes or bores, the need for checking the hole in several positions to obtain the largest diameter is obviated. The gauge has a work-holder 19 combined with feeler members over which the work 22, such as a ball bearing race, is placed, and the holder is vibrated by an electromagnetic device in the gauge to cause the work 22 to rotate on the holder to a position wherein the feelers engage the largest diameter of the work. The gauge comprises a frame 1, an electromagnet 3 supported on a spring arm 4 which is fixed on legs 5 at one end and secured at the other end to a displacement member 6, a vibrator arm 7 fixed to the member 6 at one end and extending over the armature 8 of the magnet 3, and a push-button switch 9. The member 6 consists of a frame 11, two spring arms 12, 13 supporting an armature 14 which is movable within three coils 15, 16, 17 and a stylus 18 mounted on the spring arm 13. The workholder 19 comprises a stud fixed to the member 6 and carrying two balls; a third ball 23 is carried by the stylus 18. The work-holder is vibrated by energizing the electromagnet 3 from a source of alternating current, the arm 7 being attracted to the armature 8 in accordance with the frequency of the current. The gauging is effected by the displacement of the ball 23 which displaces the armature 14 relatively to the three coils 15, 16, 17. Coil 17 is energized from an oscillator and induces current in coils 15, 16. When the armature 14 is in normal position, the voltages induced in the coils 15, 16 are equal, but when the armature 14 is displaced, the induced voltages are unequal, and the. result is shown on an electronic voltmeter suitably calibrated to read in units of ten thousandths of an inch on either side of a zero reading representing the diameter of a correct workpiece. The distance between the arm 7 and armature 8 is adjusted by a screw 26.

Patent GB-700607-A (GB)
Title: Improvements in or relating to the manufacture of alloys
IPC: B22F3/26
Filed: 1949-07-27
Abstract: A process for the manufacture of an alloy consisting of two or more metals comprises the steps of pressing a metal powder or a mixture of two or more metal powders to form a compact and, while the pressed compact is contained in a confined space, heating it in contact with the vapour or vapours of one or more volatile metals or volatile metallic compounds and sintering the product. The volatile metal may be added from a material or mixture capable of generating under the action of heat a suitable quantity of the desired vapour, the subsequent sintering also being carried out in the container.  This material or mixture may be in powder form, e.g. as a second pressed compact with or without a refractory diluent, e.g. of a metal the melting point of which is higher than the sintering temperature to be employed.  The source of the volatile metal may be a master alloy of the said metal with the base metal of the alloy to be produced, the composition of the master alloy being that of an intermetallic compound of melting point below the sintering temperature employed in the process. The metal or metals of the first pressed compact are preferably non-volatile and may be mixed with a small amount of refractory oxide and/or a small proportion of readily vapourizable substance which is completely vapourized on heating.  This compact may be formed under a pressure up to 20 tons per sq. in. and it may then be degassed before the heating.  The container, which may be an iron or steel tube, may have a slight leak and is evacuated prior to heating, the heating then taking place in an evacuated furnace chamber, the vacuum in which is maintained throughout heating and sintering.  The alloy produced may consist substantially of an a solid solution phase, e.g. of a Ni-Mg alloy.  Non-volatile metals may be introduced into the compact by means of a material or mixture comprising the said metal and either a volatile compound of the said metal or a substance which reacts with the metal to form a volatile compound.  Thus an Al-Ni alloy may be made by introducing Al into an Ni compact in the form of an Al halide. Specifications 580,774 and 700,605 are referred to.

Filed: 1923-08-07
Abstract: 221,069. Vance, A. T., and Abbott, F. J. Aug. 7, 1923. Balancing.-A device for preserving the lateral and longitudinal balance of an aircraft comprises series of solenoids adapted to actuate the ailerons and elevators when energized by currents controlled through relays connected to contacts in a U-tube containing mercury. Means are provided for preserving the U-tube at a constant temperature and for preventing unnecessary operation of the device during short quick movements of the aircraft. A U-tube 32 containing mercury. 33 has two series of contacts 38 - - 41 in each limb connected to two series of relays 17 - - 20, the return wires from which are connected to one pole of a source of current 29, the other pole being connected through a switch 59 to a contact 31 immersed in the mercury. Two series of solenoids 1 - - 4 of progressively increasing strength from the outer ends, have two armatures 6 connected together by a non- magnetic rod 7, the outer ends of the armatures being connected through cables to the ailerons or elevators. Each solenoid is connected to a switch adapted to be closed by the armature of the corresponding relay, the circuit being completed through corresponding contacts 9 - - 12, on the base-board 5 of the solenoids, and through a contact 8 on the armature 6 connected to a source of current 13. As the machine tilts, one or other of the outer solenoids 1 is energized and the corresponding armature 6 is drawn in until the contact 8 bridges the contacts 9, 10. Should further tilting take place the second solenoid 2 is energized, and, being stronger than the first, draws in the armature further and by withdrawing the contact 8 from the contact 9 cuts out the first solenoid. Similarly the remaining solenoids may be successively energized until the tilting is corrected. The armature is restored to its initial position by air pressure on the control surfaces. The tube 32 has its ends plugged and connected by a small bore tube 43 the resistance to airflow of which prevents sudden movements of the mercury in the tube. The tube 32 is enclosed in heat insulating material 44, and in a space 46 is a heating lamp 44 controlled bv a thermostat switch 48, current being supplied through wires 49, 50 connected to the source 1;).
