Abstract: 1,259,556. Altering physical properties. L. E. THOMPSON. 2 June, 1969 [19 Feb., 1969], No. 27781/69. Heading B3V. A method of stress relieving by -vibrations comprises vibrating a workpiece in the range of the resonant peak frequency for each part of the work to be relieved, and maintaining the vibration in the frequency range of each selected peak while the amplitude of the peak increases, the power required to produce the peak decreases and the frequency range decreases until the power necessary to produce the amplitude has substantially stabilized. The peak frequencies are determined by vibrating the work through a range of frequencies, e.g. 400-8000 c.p.m., and recording the changes in amplitude and the power requirement for the various frequencies. A continuous recording may be made of the treatment, and the step of vibrating the work through the range of frequencies may be repeated to determine if the stresses have been relieved or any new ones induced, requiring further treatment. A recording of amplitude against frequency before stress relieving is shown in Fig. 7 and often in Fig. 8, indicating a reduced peak 92 requiring further treatment which may require re-positioning of the vibrator on round or spherical work. Vibrations include primary waves in a direction Z, Fig. 1, secondary waves in a direction X and tertiary waves in direction Y. To stress relieve a weld R a frequency peak is chosen which produces resonance in the primary direction. Welds S, L are stress-relieved chasing frequency peaks producing resonance in the secondary and tertiary directions respectively. Apparatus for performing the method comprises an eccentric driven by a series electromotor 23 the speed of which is controlled by varying the current by a variable transformer controlled by a knob 25. The work 12 is mounted on rubber strips 28, 30 and to it is attached an accelerometer 16 including a transducer producing an electrical signal which is fed to an amplifier controlled by a knob 31. A tachometer registers the motor-speed and an ammeter the current drawn, the speed being proportional to the frequency of vibration and the current indicating the power required to produce the amplitude registered by the accelerometer. A portable cabinet 20 includes means 22 comprising an oscillograph, Fig. 2 (not shown), and/or a scriber-tape recorder, Fig. 3 (not shown), and/or a digital recorder, Fig. 4 (not shown), for recording frequency, amplitude and power.

Abstract: 1,266,621. Homopolar machines. GENERAL ELECTRIC CO. Ltd. 27 July, 1970 [1 Aug., 1969], No. 38623/69. Heading H2A. A homopolar machine comprises a stator magnetic circuit consisting of a yoke 55 formed with an annular cavity 3 in which are located annular stator members 4...8 defining a plurality of axial air gaps in each of which is located one of a plurality of annular, conducting rotor members 15 ... 19, each of the stator members comprising a polepiece 24 surrounded by conducting material 25 through which the rotor members are connected in series between terminals 26, 27. Preferably, the rotor members also comprise polepieces 24 surrounded by conducting material 25. The stator members are insulated from each other by spacers 11, and the rotor members, which are carried by a hub 13, are separated by insulating spacers 23. Connection between the members and between the stationary terminal 26 and hub 13 is effected by conducting liquid such as a sodium potassium alloy, at the points 30, 35 and 38, the liquid being circulated through the machine through ducts 28, 31, 33, 36, 39, 40, 41. Those surfaces of the stator and rotor members where connections are not required are covered by a thin layer of insulation. End plates 42 define an enclosure for the assembly of stator and rotor members which is filled with gas such as nitrogen. To alleviate magnetic pressure on the conducting liquid at the connection points, produced by the load current through the machine, a connection parallel to the tube 20 extending from terminal 26 to rotor member 15 is made through a tube (52), Fig. 3 (not shown), fixed to the stator adjacent the radially outer ends of the rotor members to provide an opposing magnetic pressure. Alternatively, one of the contact surfaces at each connection point may be slotted to increase the surface tension sufficiently to counteract the magnetic pressure. In other alternative arrangements the gaps at each connection point may have radial portions filled with liquid and of a length such that the centrifugal force acting on the liquid therein maintains liquid in axial portions of the gaps, Figs. 4-6 (not shown), or the connections may be of the type described in Specification 1,266,622, Fig. 7 (not shown). The conducting liquid provides a measure of cooling for the machine which may be supplemented by circulating water through channels in the stator members 4 ... 8.

Abstract: 1289052 Aircraft simulator visual display system; training drivers SINGER CO 3 Feb 1970 4998/70 Headings B7H and B7W A control system for a vehicle simulator visual display system (described throughout as a system for an aircraft simulator) of the type that employs the optically distorted projection of a motion picture containing scenes taken from an actual aircraft incorporates an arrangement for correcting excess cumulative positional error by means of the continuous addition of an imperceptibly small signal, proportional to one of the control signals for the distortion optics, to the input of the control system. Signals indicative of forces acting on the simulated aircraft are supplied to a flight computer 12 wherein they are doubly integrated to provide signals representative of the simulated position (X s , Y s , Z s ) of the aircraft; these signals (X s , Y s , Z s ) are then fed into an attitude computer 28 together with signals (X v , Y y , Z v ) from a film readout 26 in which is stored data concerning the position of the camera which originally exposed the film. Output signals 30, 32 from the attitude computer 28 corresponding to the lateral and vertical displacements d, h of the simulated position (X s , Y s , Z s ) from the camera flight path position (X v , Y v , Z v ) are then fed to an optical transfortuation computer 34 which develops drive signals for the distortion optics contained in an image alteration system 36, with the result that the picture is controllably distorted to correspond to movements of the simulator controls 10. Compensation for cumulative positional error is provided by the addition to the input of the flight computer 12 of a signal tapped from signal 30 via an amplifier 38 and a summing junction 42. This signal is treated by computer 12 as a force, and if its magnitude is small enough it has the same effect on the simulator as would a wind force applied to an aircraft; such a small signal is undetectable to the simulator operator over a short time period (as would a wind force be undetectable to a pilot) and tends to negate any positional error.

Abstract: 1303354 Fluid-pressure servomotor systems SOAG MACHINERY Ltd 19 April 1971 [24 Feb 1970] 8872/70 Heading G3P A supply of pressurized fluid for actuating a die casting or injection moulding machine is controlled by a valve spool 7 mechanically connected with limited axial play to a pilot spool 6 operated by a safety guard on the machine. The spool 7 is held in the position shown against the resistance of a spring 13 by fluid-pressure in a bore 5 which communicates with a fluid supply port 27 through a clearance 18, a port 22 and an annular chamber 25. When the pilot spool is raised by rotation of a shaft 34 and an arm 33, it uncovers an exhaust vent 30' and the port 22 so that pressure in the bore 5 falls. Fluid from the port 27 now flows through an uncovered port 22' and a passage 8 into a chamber 12 provided with an exhaust vent 29' and the spring 13 causes the main spool to follow up the movement of the pilot spool until the port 27 is connected with an exhaust line 28. In a second embodiment, a port situated above the port 27 and leading to a mould or die actuator is disconnected by the movement of the main spool from the port 27 before the exhaust line is opened.

Abstract: 1308458 Mounting felting needles NEEDLE INDUSTRIES Ltd 18 May 1970 [7 June 1969] 28904/69 Headings D1R and DIG A metal needle mounting member 13 for insertion in a hole 11 in needle carrier 12 of greater cross-sectional dimensions than the needle 10 has a portion arranged to grip the shank of needle 10 and an outer portion arranged to grip the internal wall of the hole in needle carrier 12. Preferably the needle and the wall may be gripped independantly. In one embodiment the outer gripping portion 14 comprises a curved tongue 17 connected by a piece 20 of shorter axial length to a rigid part 19 formed as a seating adapted to engage the internal side wall of the hole 11. The radius of curvature of tongue 17 is slightly greater than that of hole 11 so that it is deflected inwardly when the member is inserted in the hole and in pressing outwardly makes contact with the wall of hole 11 at two circumferentially spaced positions whilst part 19, which has a radius of curvature equal to or slightly less than that of hole 11, presses against the wall of the hole at a third position. Precise orientation of the mounting is thereby obtained. The needle gripping portion comprises a tongue 15 which can be resiliently displaced away from the part cylindrical seatings 21 and 22 which are axially spaced on either side of tongue 15. Three circumferentially spaced points of contact between needle and mounting are ensured by making the radius of curvature of the seatings 21, 22 slightly less than that of the shank of needle 10. To facilitate insertion of the needle 10 the needle seating 22 at one end of the member is flared outwardly, as is the corresponding end portion 16 of tongue 15. Tongue 14 may carry an extension A bearing a slot to receive the turned over end 10a of the shank of the needle. A second extension B is perpendicular to the axis of the mounting and thereby limits the extent to which the mounting can be inserted into the hole. The mounting may be symmetrical about a medial plane perpendicular to the axis (118, Figure 5, not shown) to facilitate insertion into the carrier. The mounting may be formed from strip spring steel by stamping, rolling, drawing and pressing.

Abstract: 1310350 Laminates CIBA-GEIGY (UK) Ltd 29 Oct 1970 [28 Nov 1969] 58434/69 Heading B5N [Also in Division D1] Laminates are prepared by heating superposed layers of the resin/fibre tapes described below at 170 C. and 7 kg./sq. cm. pressure for 1 hour. For greater strength the tapes may be cut so that the fibres in a layer lie at an angle to those in adjacent layers. Tows of continuous parallel carbon fibres are drawn from reels suspended in framework 1, through a solution of a first resin in bath 2 and shaped into ribbons of constant width. The ribbons are dried and aligned into an abutting edge to edge relationship. A film of second resin is applied to each side of the ribbons and the composite hot calendered so that the second resin flows about the ribbons to form a coherent tape. The tows are formed into ribbons by entering the resin tank 2 through circular holes (23, Fig. 2, not shown) in its cover, passing around grooved roller or fixed smooth surfaced rod (3), and exiting through rectangular slots 21. The drying oven 5, electrically heated to 70 C., has a partition 6 to keep solvent driven off the ascending ribbons from the descending ribbons. Tension is introduced by stationary grooved roller 8. The ribbons are aligned by grooved rollers 9, 10. In the case of a seven ribbon, 2À54 cm. tape, roller 10 has three 0À363 cm. grooves (63, Fig. 6, not shown) and four 0À363 cm. lands (64), the lands being aligned with four 0À363 cm. grooves (61) on roller 9. The seven ribbons emerge in abutting, edge-to-edge fashion, and are hot calendered between resin films supplied by rollers 13, 14, by means of rollers 11, 12, having a 2À54 cm. groove (71, Fig. 7, not shown) on roller 12 and a corresponding shoulder (72) on roller 11. One or both rollers 11, 12 is heated to 70 C. Rollers 9, 10 and 11, 12 are spring-biased together. Alternative shaping devices to the slots (21) are described. Thus two plates with a separation equal to the desired thickness of the ribbons may carry pegs whose separation determines the thickness. Alternatively the shaping device may comprise 2 non-rotating grooved rods. In another embodiment an individual bath in the form of a U-tube (81, Fig. 8, not shown) is provided for each tow, which exits through a flattened cone (82). A list of thermoplastic and thermosetting resins is given. In the example, the first resin is an epoxide formed from 2,2-bis-(4-hydroxyphenyl) propane and epichlorohydrin, and is dissolved in methoxyethanol or other volatile solvent in the presence of dicyandiamide, and the same epoxide was used as the resin film, which was supported on a releasable paper backing. Between 5 and 40% of the resin is applied in bath 2. Preferably one or both resins remain at the A or B stage.
