Title: Improvements in electromagnetic pick-ups for disc records or the like
IPC: H04R11/04
Filed: 1928-12-31
Abstract: 311,366. Dieux, J. May 10, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Gramophone pick - ups. - In an electromagnetic pick-up the vibrating armature comprises a magnetic part 4', Fig. 2, adjacent the poles of the electromagnet 2 and parts 4<2>, 4<3> of non- magnetic metal, non-resonant alloy, ebonite or fibre. This construction provides a light armature and facilitates damping of the parasitic vibration of the needle 5 and armature. The needle 5 is mounted eccentrically in the armature. The electromagnetic unit is mounted in a casing 1, Fig. 1, pivotally supported on a forked arm 11, the boss 13 of which is rotatably mounted through the intermediary of a ball bearing on a spindle carried by the base 18. In a modification, the boss 13 carries the spindle which engages in a ca vity in the base 18 and rests on a ball within the cavity. In order to relieve the pressure of the needle on the sound record, a counterweight 12 may be provided on the casing 1 or the upper part of the casing may be formed so as to constitute a counterweight. In a further modification, the casing 1, Fig. C, is supported on an arm 20 which is pivoted on an arm 21 and carries a counterweight 12.
Patent GB-384806-A (GB)
Abstract: 384,806. Changing wave form. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Gardiner, P. C. ; 210, James Street, Scotia, New York, U.S.A.) Dec. 16, 1931, No. 34875. Convention date, Dec. 16, 1930. [Class 38 (ii).] Relates to the use of oscillations, having a fixed frequency, and an amplitude .varying in accordance with the light and shade of a picture, for interrupting a carrier wave to produce impulses having the same frequency but having a duration corresponding to the amplitude of the oscillations, and consists in using oscillations of wave form given by x = k/y. Light from a picture 3, Fig. 1, is interrupted by a chopper wheel 6 and falls on a photoelectric cell 8 producing oscillations in the transformer 9 having a wave form 30, Fig. 2. The oscillations are fed to the grids of two valves 10, 11 connected in push-pull, whose plate circuits include a transformer 14. This amplifier produces a wave form 31, Fig. 2, which is subjected to full-wave restification by the valves 16, 17 producing in the grid circuit of the valve 22 an oscillation of wave form 32, Fig. 2, which is approximately given by the equation x = k/y. The valve 22 is biassed so as to pass current when the oscillation 32 reaches an amplitude a and for values below a no current is passed while. for values slightly above a the valve passes its maximum current, so that the transmitter 23 is interrupted in accordance with the light and shade of the picture. The apertures in the chopper wheel 6 may be triangular, Fig. 4, the beam 4 having a triangular cross section to produce the wave form 30, Fig. 2; instead of using an amplifier to produce the wave form 31, Fig. 2, it may be produced by apertures of the shape shown in Fig. 5, co-operating with a beam of cross section 6a, Fig. 5.

Title: Magnetostrictive pulse-time modulator
Inventor: POWELL ALBERT EDWIN
IPC: H03K7/04
Filed: 1958-12-02
Abstract: 865,925. Telemetering systems. BYFORD LABS Inc. Dec. 2, 1958, No. 38766/58. Class 40 (1). [Also in Group XL (c)] Time-modulated pulses are produced by variably positioning pick-up coils 40, 46, 50, 54, 56 along a magnetostrictive delay rod 16 in accordance with modulation signals applied to them, the coils receiving pulses from a transmitting coil 11 at the other end, and applying their combined and variably delayed outputs to a radio transmitter or line along with an equallyspaced synchronizing pulse train. The coils may be movedby mechanical connection with coils 41, 47 movable against spring action in the field of permanent magnets 44, 48 by modulation current traversing them, or may be responsive via an aneroid capsule 53 or bi-metallic strip 55 or pressure-responsive piston 57 to signal pressure or temperature. End weights 17, 18 prevent reflections from the ends of the rod. The rod may be replaced by a ribbon or plurality of wires. Alternatively the coils may be coupled to a moving coil longitudinally movable in a pot magnet variably energized by modulation current, all being coaxially mounted on the rod. In a modification the pick-up coil is fixed to the rod and the transmit coil 11 is movable and attached to a moving-coil in a modulation energized electromagnet, and is mounted coaxial with but just off the line, so that only the positive or negative half-cycles of a modulating wave are transmitted, and during absence of modulation no pulses are transmitted. In a further modification the transmitting coil is connected to one end of the rod and both it and the rod are axially moved by modulation relative to a stationary pick-up coil.

Title: Verbal report on a counter reading
Inventor: SHORROCK STANLEY
IPC: H04M11/00
Filed: 1966-08-31
Abstract: 1,138,742. Electric digital signalling systems. SHORROCK DEVELOPMENTS Ltd. 22 Aug., 1967 [31 Aug., 1966], No. 38805/66. Heading G4H. [Also in Division H4] A substation circuit responds to an incoming call to transmit in verbal form the numerical settings of a plurality of number wheels. As described the number wheels are the wheels of a counter which counts the number of items produced by a machine. A ringing tone detector 18 responds to an incoming call by looping the line and enabling a switching unit 16. The switching unit starts a motor 14 causing a magnetic drum 12 to rotate. A reading head 25 enabled at this time, transmits an initial message specifying which counter is involved. A motor 7 is then enabled causing a wiper 5 to slowly sweep its contacts. Alternate contacts connect individually to wipers 2, 3 and 4 respectively of further wiper switches, while the remaining contacts connect back to the switching unit for control purposes. The wipers 2, 3 and 4 are set by the number wheels in accordance with their settings so that for each wheel the associated wiper engages a corresponding contact and selects a reading head 11 associated with a track on which the appropriate spoken digit is recorded. Thus as the wiper sweeps its contacts the settings of successive number wheels are read-out in verbal form. Further wiper switches and drums may be provided to read a plurality of counters and/or to announce the denominations of each number wheel. Tapes may be used instead of drums.

Title: Fusion welding processes
IPC: B23K15/00
Filed: 1972-08-21
Abstract: 1389271 Welding by fusion; making welding wire GENERAL ELECTRIC CO Ltd 19 Oct 1973 [21 Aug 1972] 38910/72 Headings B3A and B3R In a method of fusion welding together two metal workpieces (e.g. tubes, end-to-end, or plates), wherein an insert is placed between the workpieces before application of heat, said insert is made by inserting a deoxidant-including metal powder, granules, filings or foil filling into a tube of weldable metal or alloy, preferably the same as one or both of the workpieces, consolidating, as by swaging, the filled tube to form a composite rod and working, as by swaging, rolling or pressing, to form said insert. The thus formed insert may be wire which may be subsequently rolled to produce a flattened strip insert. The formed insert may be annealed to promote some diffusion between the metal of the tube and the filling. The method is particularly suitable for welding by electron beam (glow discharge or thermionic cathode). In examples, strips of Nb, Ti or Zr foil or a mixture of Fe and Si powders are/is inserted into a mild steel tube (0À25 inch O.D., 0À05 inch wall thickness) which is then cold swaged first to rod and subsequently to a 0À125 inch diameter wire. The inserted Nb, Ti, Zr or Si, serving as a deoxidant, constitutes approximately 1% composite weight. The composite wire insert is placed in a channel constituted by grooves formed in the mating edges of 0À25 inch thick mild steel workpiece plates, and welding is effected by glow discharge electron beam.

Title: Automatic Turning Control for Television Sets
IPC: H04N5/50
Filed: 1967-08-24
Abstract: 1,192,405. Automatic frequency control systems. INTERNATIONAL STANDARD ELECTRIC CORP. 24 Aug., 1967 [26 Aug., 1966], No. 39055/67. Heading H3A. An automatic frequency control signal for controlling the frequency of the local oscillator of a television receiver is derived from the video amplifier 2 through a high-pass filter 4 and a rectifier 5 controlled by flyback pulses 7, the output of the rectifier 5 passing through a low pass filter 8 to provide the control signal. This signal may be used on its own (Fig. 1, not shown) but is preferably subtracted from a similar signal derived through low-pass filter 10, pulse-controlled rectifier 11 and lowpass filter 12, the latter signal being adjustable (by means not shown) to provide a zero output at optimum local oscillator frequency. In a practical circuit for units 4, 5 and 8 (Fig. 3, not shown) the source of video signals (15) is shunted by a normally conductive diode (17) which is cut off on the application of flyback pulses. The source (15) is connected through a filter (21, 22) to a rectifying diode (24) connected to a further filter (25-27). The circuit for units 10-12 is the same except for the first filter which is re-arranged as a low-pass filter. Equality of operation between colour and black- and-white signals may be secured either by removing the colour burst pulses or by introducing an equivalent signal from the colour killer circuit.

Title: Method of making semiconductor devices with ion beams
IPC: H01L23/29
Filed: 1969-08-05
Abstract: 1,214,437. Making semi-conductor devices. HUGHES AIRCRAFT CO. 5 Aug., 1969 [5 Aug., 1968], No. 39162/69. Heading H1K. Ion bombardment is used in at least three different operations in the production of a semi-conductor device. In an embodiment these operations lead to the formation of an IGFET. An N-type silicon body 30 is subjected to ionimplantation to produce boron-doped concentric regions 32, 34. Bombardment with oxygen or nitrogen ions is then used to form an oxide or nitride coating 36 by reaction with the silicon body. Holes are formed in the passivation 36 for the later provision of evaporated aluminium source 38 and drain 40 contacts. An annular portion of the passivation is thinned by bombardment with inert ions such as argonthe source and drain contact apertures are formed by the use of a more energetic argon ion beam or by using a longer exposure time. (If desired, the aluminium gate electrode 42 may be used as a mask during the provision of an ion-implanted extension 32<SP>1</SP> to the drain region.) The three operations may be applied to the production of diodes, bipolar transistors, and integrated circuits. Germanium is an alternative semi-conductor, and phosphorus may be ion-implanted.

Title: Improvements in or relating to the production of alkyl aluminium compounds
IPC: B01J19/00
Filed: 1960-11-15
Abstract: <PICT:0916714/IV (b)/1> Alkyl aluminium compounds of general formula AlR3 in which R represents a lower alkyl radical are converted into compounds having higher alkyl radicals than the starting material by a process in which they are sprayed into a stream of ethylene being conveyed at a flow velocity of 1 to 50 m/minute and with a residence time of 1 to 20 minutes through a reaction chamber maintained at a temperature between 120 DEG  and 200 DEG C., the reaction chamber having a diameter up to 3 cm. and a length at least 1,000 times the diameter.  It is preferred that the starting material should contain at least two carbon atoms.  The apparatus comprises a reactor A, a condenser B, a pressure separator C, a regulating valve D, a flow meter E, a circulation compressor F, a pump G for liquid under pressure and a mixing component H.  The reactor A consists of a copper tube, suitable dimensions being a diameter of 8 mm. and length 40 metres (capacity 2 litres).  This is wound with a 3% inclination on to an iron tube b of diameter about 50 cms. and open top and bottom.  The assembly is placed in an oil bath c and a stirrer d disposed inside the iron tube to force the oil downwards in the tube and upwards through the annular gap between the iron tube b and the wall of the bath c.  This ensures that the reactor is continuously washed by the oil in the bath. An immersion heater e is provided for heating the oil.  The ethylene stream is fed in via the compressor F to the mixing unit H where it entrains the alkyl aluminium starting material in atomized form.  It passes through the reactor, unreacted ethylene being separated in the separator C and recirculated, the growth product remaining behind and drawn off as necessary.  Details of operation are given in the Specification.  Specifications 713,081, 742,642 and 763,824 are referred to.

Title: Improvements in or relating to heat exchangers
IPC: F22B1/06
Filed: 1956-12-27
Abstract: 819,825. Heating steam boilers by hot liquids. STEIN & ROUBAIX. Dec. 27, 1956 [Aug. 27, 1956], No. 39360/56. Classes 123(2) and 123(3) In an apparatus for exchanging heat between two fluids which must not be allowed to come into contact, for example, molten sodium coolant from a nuclear reactor and water to be converted into steam, the heat exchange occurs through a third fluid and means are provided for relative expansion and contraction movements of the various parts of the device. In the form shown, the apparatus consists of a casing 3 having three cylindrical portions connected by return bends 5. The ends of the casing are closed by tubeplates 10 between which extend tubes such as 1 through which water at a high pressure flows as indicated by the arrows f. Each of the cylindrical portions of the casing is closed by tube plates 4 connected by tubes such as 2 each of which is disposed coaxially about a tube 1 where the latter passes through the respective cylindrical portion. The said portions are interconnected by pipes 6 and the first and last portions provided respectively with an inlet and outlet for the flow of molten sodium coolant as indicated by the arrows g The spaces between the tube plates 10, 4, the annular gaps between tubes 1, 2 and the return bends 5 are filled with mercury, the combined mercury space being connected by a pipe 11 to an expansion chamber 12 which is itself connected with a bottle 13 containing an inert gas which serves to maintain a constant pressure on the mercury, this pressure lying between that in the tube 1 and that in the casing 3. The bottle 13 is of small capacity so that any leakage of mercury into the casing will quickly be detected by a drop in pressure as indicated by a gauge 14. Any leakage from the tube 1 into the mercury results in the opening of a drain valve 7 which operates at a predetermined overpressure in the mercury space allowing the mercury to drain into a tank 9. The location of the bends in the tube 1 in the unheated sections 5 of the casing allows for the free expansion and contraction movements of the tube relative to the tubes 2. The water may be passed through three heat exchangers in series, the first acting as a preheater, the second as an evaporator and the third as a superheater. In other forms, preheating and evaporation occur in a single element, the working fluid being circulated by an external pump or by convection or the element may operate on the "once-through" principal a pump forcing water into the tube 1 and superheated stead being delivered from its outlet.

Abstract: 890,666. Batteries. UNION CARBIDE CORPORATION. Nov. 20, 1959 [Nov. 21, 1958], No. 39416/59. Drawings to Specification. Class 53. A nickel-cadmium or other secondary cell with alkaline electrolyte is provided with a positive electrode consisting of nickelous hydroxide mixed with potassium hydroxide solution, and a negative electrode comprising a porous nickel plate containing cadmium oxide or hydroxide. In this condition the cell is in the discharged state, and it is sealed before being subjected to the electrolytic forming process. In the case of cadmium oxide, enough additional KOH is added to ensure conversion to the hydroxide. In a specific example the positive electrode was moulded from a mix consisting of 70 parts by weight of powdered Ni(OH)2 and 30 parts fine graphite powder wetted with 13.8 parts of 35% aqueous KOH. The moulding produced pellets of which two could be placed together to form a split cylinder around which a cylindrical negative electrode, rolled from sheet, was placed with intervening insulation, the whole being inserted in a nickelplated, drawn sheet steel container and then sealed.

[Class 139.] In an electric clock with a synchronous motor and an auxiliary movement, the latter, which is wound by'the motor and actuates the hands only when the motor ceases to actuate the electric clock, runs continuously. The motor b drives the hands i, through gearing a, c, e, d (carried on e), g, h. Between the auxiliary movement P and this gearing is a differential, n being a planet wheel, and k, m sun wheels. k is fixed to shaft o and m is attached to bush q loose on shaft f. This bush also carries a ratchet wheel r and gear s. Planet n is carried in a second ratchet wheel t. Normally, whilst motor b is running and driving the hands, the motor attracts an armature v and pawl w locks ratchet b and sun wheel m, so that n rotates idly. When the current fails, v drops, wheels r, m are released, and part x engages wheel t carrying the planet n. The auxiliary P then drives the sun wheel m and wheels, s, d, g &c. to the hands.
