Title: Improved method and means for supercharging and scavenging internal-combustion engines
IPC: F02B37/04
Filed: 1949-07-11
Abstract: 677,783. Supercharging and scavenging engines. BUCHI, A. July 11, 1949 [Sept. 25, 1948], No. 18313/49. Class 7(ii) [Also in Group XXVI] In multicylinder engines wherein the exhaust gases or cylinders 1 ... 6 are conducted separately in at least two manifolds I, II to the inlets 13<SP>1</SP>, 13<SP>11</SP> of a turbine 12 coupled to a blower so that, at least at the beginning of the exhaust period of each cylinder, pressure surges are produced upstream of the turbine and subsequently a pressure lower than that for supercharging or scavenging the engine is created, a portion of the exhaust gases of at least two cylinders firing at different times simultaneously deliver alternately varying amounts of energy separately through different segments of the turbine blading and into at least one ejection-like means A disposed downstream of the turbine so that the gases under a high energy alternately arriving in the means produce, on being mixed with the gases under a smaller energy alternately arriving in the means, in a mixing part 18 a pressure lower than atmospheric pressure downstream of the blading to effect a greater mass flow of air- or gas through the cylinders so that the supercharging and scavenging operations of the engine are intensified and the power output of the turbine is increased. A diffuser 20 and an axially-movable deflector to vary the flow area of the diffuser may be fitted to the means A to intensify the ejector-like action of the confluent gas portions. The Specification also describes the supercharging and scavenging of (a) an eight-cylinder four-stroke engine, Fig. 7, (not shown) (b)' an eight-cylinder fourstroke engine, the exhaust gases being delivered in manifolds to a turbine with twin ejector means, Fig. 10 (not shown) (c), a six-cylinder four-stroke engine having three exhaust manifolds and a turbine including a three-part ejector means, Fig. 14 (not shown) (d), a four-stroke engine comprising sixteen cylinders in " V " formation, the turbine having twin ejector, Fig. 18 (not shown), and (e), a six cylinder two-stroke engine, Fig. 21 (not shown).

Title: Improvements in or relating to automatic telephone exchanges
IPC: H04Q3/62
Filed: 1959-05-29
Abstract: 910,967. Automatic - exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 29, 1959 [June 3, 1958], No. 18377/59. Class 40 (4). Privileged subscribers on finding a wanted subscriber busy may signal the exchange, by means such as dialling 1, to disconnect busy tone and apply pip-pip tone to the established connection to indicate that one of the parties is wanted, and may send a further signal to the exchange to disconnect or reduce pip-pip tone and actually enter the connection. A privileged subscriber has access over the line Ab1 to the circuit illustrated and onwards over the line Ab2 to a wanted subscriber whom it is assumed is busy with a call. Busy tone is consequently connected over terminal 6 and feed transformer 5. By dialling 1 the privileged subscriber operates a relay A which locks up in a circuit shown schematically at 8, connecting line Abl to line Ab2, disconnecting busy tone but connecting up over transformer 9 and from terminal 10 pip-pip tone of an amplitude and repetition rate sufficient to disrupt conversation in the connection with which the wanted subscriber is engaged. In face of this disruption the engaged parties may hang up and the wanted subscriber in so doing returns earth to the exchange to operate a relay B which connects ringing current to his line Ab2 from terminal 7. On lifting his hand-set in response to ringing the wanted subscriber is connected with the privileged subscriber. The engaged parties need not hang up and, if they do not, the privileged subscriber by means such as an earthing button at his subset operates and locks up a relay C in the circuit 8. Relay C disconnects pip-pip tone from terminal 10 and substitutes a subdued pip-pip tone from terminal 11 over which conversation is possible and the purpose of which is to indicate that a conference call is in progress. Further privileged subscribers may break in to extend the conference.

Title: Improvements relating to the production of fibres of glass or other materials
IPC: C03B37/02
Filed: 1939-06-24
Abstract: 530,468. Making fibres from glass or viscous material. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N. V. June 24, 1939, No. 18442. Convention date, June 25, 1938. [Class 56] [Also in Group IV] A method of producing fibres from viscous or plastic material that hardens rapidly, particularly glass, consists in subjecting the fibres while they are still in the viscous or plastic state to the action of vibrations impressed on the surrounding medium. The vibrations may be acoustic or supersonic, and they are produced or emitted in the vicinity of the point of formation of the fibres. The fibres may be drawn from orifices in a bushing 4, Fig. 1, by the action of blasts of gas or vapour from a blower 5. The air surrounding the flowing material is caused to vibrate by making the blower nozzle of suitable form, or by arranging below the blower a pipe 7 the edge of which is struck by the blast or by air currents induced by the blast. The pipe has an extension in the form of a horn 8 which constitutes an acoustic resonator. The vibrations may be generated transversely to the length of the fibres by a piezo-electric quartz oscillator 9, Fig. 2. The oscillator may be arranged vertically, as shown, or it may be arranged horizontally and the vibrations directed on to the fibres by a reflector.' The vibrations may be generated, also, by magnetostriction in a bar of nickel or ferro-nickel.

Filed: 1972-04-21
Abstract: 1376466 Making spiral duct-defining units AGA AB and S KNOOS 21 April 1972 [23 April 1971] 18597/72 Heading B3A [Also in Division F4] A method of fabricating a spirally-wound duct-defining unit comprises simultaneously winding at least one strip (2), Fig. 1 (not shown), and at least one spacer element (3) such that the spacer element radially spaces the turns of the strip, securing the turns of the strip by passing elongate fixing elements, e.g. pins 9, Fig. 2, through respective sets of holes, which are radially aligned in the turns of the strip and the outermost holes are spaced about the circumference of the wound strip, each fixing element preventing movement of the strip turns in a plane perpendicular to the fixing element, and removing at least part of the spacer element from the space between some at least of the adjacent turns of the strip. Wires 4, 5, which comprise the spacer element, are wound together with a strip about a core between shields 6, 7, and holes are drilled through the coiled strip to accommodate the pins 9. When winding is completed, the shields 6, 7 are removed and the wires 3, 4 pulled out of the coil or they may be dissolved or melted out by heating. Two or more strips with their spacer elements may be wound simultaneously and alternate elements removed to form flow passages for heat exchange between two media, A, B, Fig. 7. The medium B is supplied through a pipe 29 on either side of the unit and the pipes are secured by soldering, gluing or by dipping in a metal bath. A plurality of units (16)-(20), Fig. 5 (not shown), may be located in axial relationship for use in refrigerating plant or as a thermal regenerator for a gas engine. A liquid fuel burner, Fig. 11, is fabricated by simultaneously winding two strips together with axially spaced spacer elements, which are removed from between alternate turns to form axially directed ducts 38, through which air is passed, and ducts 40 containing metal netting 41 for pumping the fuel by capillary action. In alternative forms of burners, capillary pumping takes place without the use of wire netting, or all the spacer elements are removed and netting is placed between alternate turns of the unit or the netting is located upstream, in the direction of fuel flow, of the spacers, Figs. 13-15 respectively (not shown).

Title: Improvements in and relating to inductive couplings or transformer devices, particularly applicable to gyro magnetic compasses
IPC: G01C19/36
Filed: 1943-11-11
Abstract: 600,605. Transformers. SPERRY GYROSCOPE CO., Inc. Nov. 11, 1943, No. 18805. Convention date, Nov. 11, 1942. [Class 38 (ii)] [Also in Group XXXVIII] In a gyro-magnetic compass combination in which the movements of a magnetic compass 11 are transmitted through a selsyn system to a gyro 21, alternating current is transmitted to the rotor windings 28 of the transmitter by an inductive coupling comprising coaxial coils 31, 32 mounted for relative rotation about their common axis. The rotor winding 28 of the selsyn transmitter is mounted on a shaft 15 carrying a compass follower 14 whilst the rotor winding 40 of the selsyn receiver is mounted on a shaft 39 secured to the vertical ring 20 of the gyro. The casing of the latter carries magnets 25 co-operating with a coil 24 which is energized from an amplifier 41 whenever a signal is received due to lack of correspondence between the two rotors. Thus, the gyro is caused to precess, bringing the receiver rotor into positional agreement with the transmitter rotor. An inductive coupling similar to that represented by the coils 31, 32 may be used between the receiver rotor 40 and the amplifier 41. Fig. 4 shows an inductive coupling comprising fixed and rotatable coils 53, 57 associated with magnetic core elements 54, 58, the flanges of which are slotted to reduce eddy currents. The movable coil is mounted on the spindle 15 carrying the rotor 28 of the selsyn transmitter the two structures being combined in a common housing 45. The Specification as open to inspection under Sect. 91 states also that an inductive coupling comprising three pairs of coaxial coils may be used for transmitting three-phase A.C. to the gyro driving motor (Fig. 9, Cancelled, not shown). This subject-matter does not appear in the Specification as accepted.
