Title: Improvements in or relating to acoustic devices
IPC: H04R9/04
Filed: 1929-01-23
Abstract: 308,776. Electrical Research Products, Inc., (Assignees of Giles, L. W.). March 31, 1928, [Convention date]. Loud-speakers; magnetic instruments; diaphragms.-A moving coil acoustic device, such as a loudspeaker, has the coil centred by spring members, preferably elliptically shaped, arranged tangentially with respect to the coil. The Figures show a construction of moving coil loud-speaker employing a diaphragm 1 comprising a frustoconical section 2 and a conical section 3 having its base secured to the frusto-conical section at a point intermediate the inner and outer ends thereof. The conical section stiffens the diaphragm so that it is capable of vibrating as a whole through the entire audible frequency range and prevents interference between the air pressures at the top and bottom of the inside surface of the frusto-conical section. The stiffening member instead of being conical may assume other shapes, e.g. flat. The outer edge of the diaphragm is supported on flexible material 4, such as silk, rubber, thin leather, &c., clamped between rings 5, 6 and has its inner edge secured to a cylindrical member 16 carrying a coil 8 and formed with a plurality of lugs 15. The coil 8 is disposed, in the annular air gap formed by concentric pole-pieces 11, 13, the pole-piece 13 being integral with the core 10 whilst the pole-piece 11 is detachably secured thereto by screws 58 to permit assembly of the winding 12. A ring 36 is secured by screws 34 to the pole-piece 11 and carries arms 30 for supporting the ring 5. Ring 36, arms 30 and ring 5 are preferably formed as an integral structure. The coil 8 is centred in the air gap by a number of elliptically shaped springs 14 spaced equally and tangentially around the coil. One end of each spring 14 is mounted on a lug 15 by means of a screw 21, insulating bushing 22, insulating washer 23 and nut 24 whilst the bottom of each spring is mounted on a terminal 54 'by a screw 42. The terminal 54 is mounted on the pole-piece 11 by screw 39, insulating bushing 43 and insulating member 41. The two ends of the coil 8 are secured to the screws 21 of two of the springs and wires 50 are run from the corresponding terminals 54 to contacts mounted on an. angle iron carried by the ring 36.

Title: Automatic steering system for ships
IPC: G05D1/02
Filed: 1975-01-20
Abstract: 1492602 Automatic control of steering FINDLAY IRVINE Ltd 20 Jan 1975 [18 Jan 1974] 02386/74 Heading G3R In an automatic steering system in a ship the rudder is adjusted in response to the difference between a control signal V' which is a function of course error plus its first and second derivatives and the rate of change of rudder angle. It is explained that this enables the rudder to maintain an offset (for weather, sea-state &c.) without the use of an integrator. The second derivative term provides damping. In operation, when the error and hence V is zero the rudder stops in its instant position. The control signal is limited to a prescribed maximum; when this is reached the rudder angle assumes a fixed value. The rudder servo is not described in detail.

Abstract: 875,362. Assembling force fits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 6, 1960 [Jan. 22, 1959], No. 2457/59. Class 83 (4). A method of adjusting the axial position of a rotatable shaft 1 within the predetermined limits of end play by the use of collars 7, 8 having an interference fit on the shaft and cooperating with a fixed machine part, e.g. a bearing 2, is characterized by placing the collars on the shaft with an interference fit in positions such that the end play is greatly in excess of the amount finally required, running the machine and marking the free-running position of the rotating parts, setting the shaft when stationary to the marked position, relieving the contact between collars and shaft and adjusting the collars axially to set the freerunning position at the mid point of the required end plate and finally restoring the contact between the collars and the shaft. The interference fit between the collars and shaft is relieved by supplying fluid pressure from passages in the shaft or collars to an annular recess 9 in the bore of each collar and the collars are axially adjusted on the shaft by means of nuts 6 screw-threaded on the shaft. To facilitate the axial adjustment of the collars a horseshoe-shaped templet having a thickness equal to half the desired end play is placed between the end face of the bearing 2 and each collar.

Title: Method and apparatus for joining two threads
IPC: D01H15/00
Filed: 1974-01-18
Abstract: 1470787 Joining yarns C P ISERN 18 Jan 1974 [19 Jan 1973] 02554/74 Heading D1W Two similar staple fibre yarns or rovings are joined by gripping each of the yarns at two spaced apart locations so as to define a yarn length therebetween, generally equal to the fibre length; twisting each length to untwist fibres therein from each other; moving apart the two locations of each yarn so as to break the lengths and thereby provide each yarn with an end having fibres which are untwisted from each other; separating or opening (as by electrostatic repulsion) the fibres of a first one of these ends; inserting the other of the ends into the separated fibres of the first end; separating from each other the fibres of the inserted end so that the fibres of the two ends cross and interlace and finally imparting an axial twisting motion to at least one of the ends so as to twist the fibres of the two ends together to complete the join (which should be of the same structure and physical properties as the yarns). In the operation of the apparatus shown, a yarn is placed in a slotted conical member 11 of a guide 8 and held by three grippers 13, 14 and 17 and 20; flywheel 18 is rotated to untwist the length of yarn between it and gripper 13, 14 and gripper 17 is then retracted from gripper 13, 14, thereby breaking the length of untwisted yarn to form a beard 4. A second yarn is positioned in guide 9 and held by three grippers 15, 16 and 21; guide flywheel 19 is rotated to untwist the length of yarn between grippers 15 and 16 (also to impart extra twist to the length between groups 15 and 21) and gripper 16 is then retracted from gripper 15 to break the yarn and leave a beard 4 in a slotted nozzle 10. A comb (not shown) may be moved along the slots of both guides to render the beard fibres parallel. The untwisted fibres 5 in member 11 becomes electrostatically charged which induces their separation and attraction to member 11 and a charged ring 12 so as to form a "mouth" into which the fibres of the other bearded end are inserted as the guide 8 (including member 11) is then moved so that nozzle 10 with fibres protruding from it is inserted into member 11. The inserted fibres also become electrostatically charged and open so that the fibres of both ends cross and interlace. Gripper 15 is released so that the extra twist runs through the untwisted ends and twists them to form the joint: further twist may be added to the joint zone by rotation of gripper 20 after release of gripper 13, 14.

Abstract: 396,096. Refrigerating. WILLSIE, H. E., 8419, Euclid Avenue, Cleveland, Ohio, U.S.A. Jan. 29, 1932, No. 2761. [Class 29.] Absorption machines.-A syphon conduit 26 for draining liquor back from a sump 24 in the evaporator 18 of a machine working on the reversing system is arranged in heat exchange at 27 with the vapour expulsion pipe 8 of the generator-absorber 1, whereby the heat of the expelled vapour at the end of the generating period serves to evaporate liquid in the drain pipe and thus produce a back pressure therein and prevent further drainage. The generatorabsorber has a liquor circulation loop 3, 6 including a coiled portion 5 located in a brine tank 7, and the vapour expulsion pipe connects with a liquid seal 11, from which vapour passes by pipe 14 to a rectifier coil 15 located in a brine tank 16. The rectifier is connected by a bent pipe 17, 19 to the evaporator, and a pipe 21 connected to the slanting portion 19 of this bent pipe leads to a condenser coil 22 in a further brine tank 23. Some expelled vapour passes direct from the rectifier to the evaporator, but the greater part flows down the pipe 21 to the condenser, and at the beginning of the absorption period the condensate rises through the pipe 21 and flows down the pipe 19 to the evaporator. The vapour returns from the evaporator through the rectifier to the trap 11, and is then diverted to a pipe 12 connected to the liquor circulation loop at a point 13 below the normal liquid level in the generator-absorber. The drain conduit 26 has a widened bore where it adjoins the expulsion pipe 8, to which it is welded at 27, and is connected to the return vapour pipe 12 at a point 29 above the generator-absorber level. The brine in the several tanks may be cooled by water circulated through jackets 31, 32, 33 in series. The disposition of the parts in a divided flue at the back of a refrigerating cabinet is described, the condenser and rectifier tanks being in one part of the flue and the generator-absorber, liquid trap and connecting pipes in the other part. The drain conduit may include a horizontal loop with one limb welded to a horizontal part of the vapour expulsion pipe, and the loop is embedded in insulation so as not to be subjected to the cooling action of the draught through the flue.

Abstract: 875,973. Electrical digital data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 28, 1960 [Jan. 30, 19591, No. 3059/60. Class 106 (1). [Also in Group XL (a)] In apparatus for determining the distribution of magnetic or electrostatic data representations on a surface, a beam of electrons directed towards the surface is reflected by an electron mirror when it is immediately adjacent the surface, and the deflection of the beam due to the effect of the data representations is measured to indicate the distribution thereof. As shown, an electron beam 31a from cathode 12 is scanned over surface 21 by two sets 26, 27 of deflection plates, the second set being provided to return the beam to a path which is normal to surface 21. Since surface 21 is slightly negative with respect to cathode 12, the beam is reflected before actually impinging thereon and, in the absence of any data on surface 21, returns along path 31a but the presence of a magnetic or electrostatic data representation immediately adjacent the beam causes it to be reflected along a different path 31c and so impinge upon one of the collector plates 17, 18 causing an output signal from differential amplifier 19. The beam is caused to rest on each elemental area of surface 21 for a short time by applying a stepped waveform to the horizontal deflection plates. To have random access to the data stored on surface 21 a counter connected to a beam-blanking circuit may be utilized. In an alternative embodiment, collector plates 17, 18 are replaced by a centrally-apertured electrode having a cathodoluminescent coating, light pulses from which are detected by a photomultiplier structurally combined with the cathode-ray tube. The electrical pulses from the photomultiplier, as are those from differential amplifier 19, are synchronized with the scanning circuits to provide an indication of the distribution of the detected data on surface 21. The end face of the cathode-ray tube instead of itself carrying the recorded data, may be provided with a magnetically or electrostatically permeable area across which is moved a tape carrying the recorded data, the vertical deflection plates being dispensed with.
