Title: Improvements in instruments for recording and/or indicating vibrations, accelerations, or the like
IPC: G01P1/12
Filed: 1943-09-06
Abstract: 587,272. Accelerometers ; vibrometers. STEAD, E. B., and McINNES, Ltd., D. Sept. 6, 1943, No. 14511. [Classes 106 (iii) and 106 (iv)] An instrument for recording vibrations comprises a mass supported by parallel springs anchored to the frame for deflection in a single plane under the inertia of the mass, and a motion-magnifying recording arm having a bearing on said frame and a knife-edge connection to the mass so that the arm oscillates with the mass, the arm having a pivotal mounting comprising a knife bearing. As shown, a device for recording acceleration or vibration in a vertical direction comprises a frame 2 supported on three feet 4. A rectangular prism 6 is suspended from the frame by a pair of parallel leaf springs 7 and the natural frequency of oscillation of the prism 6 is varied according to which of several weights 6<1>-6<4> is screwed into a recess 11. Alternatively,. one of the springs is easily changeable. Movement of the prism 6 is transmitted through a spring 20 and knife-edge bearing 21, 22 to a rock-shaft 17 mounted in further knife-edge bearings 18, 19. The rock-shaft 17 is secured' to a motion-magnifying arm 14 of very light construction and carrying a roller 48 tracing over a band of paper 32. The movements of the arm 14 are damped by an oscillatory vane in a housing 30, the damping force being adjustable by a screw 31 controlling the usual byepass. The paper 32 passes from a spool 33 over an impression roller 34 and through' the nip between a guide-roller 35 and a driving roller 36, the nip being adjustable by clamping nuts 42, 43. The screw 41 bearing the nuts 42, 43 can be swung to one side to allow a frame 39 supporting the paper feed to be lifted out of the device, whereby a new spool may be inserted. The driving roller 36 is driven by a clockwork motor, Fig. 3, wound up by a key 65, started and stopped by a lever 66, Figs. 1 and 2, and regulated by a lever 47, Fig. 2. The roller 48 marks the paper 32 through an ink ribbon 49 fed at a slow rate from one spool 50 to another. An eccentric 58 reciprocates a rod 59 pivoted to a double pawl 53 pivotally mounted at 55 on a pawl-carrier 56 pivotally mounted on a post 57. The pawl 53 thus advances one or other spool 50. A spring- pressed arm 64 indicates when the drive of the ink-ribbon should be reversed, whereupon the operator swings the end of a lever 60 from one end of slot 62 to the other. The spring 54 is then caused to act on the opposite side of the pivot 55 and the pawl 53 begins to drive the other spool 50. Specification 587,308 is referred to.
Patent GB-1147611-A (GB)
Title: Improvements in or relating to record/playback systems
Inventor: TRIMINGHAM AUSTIN LOCH
IPC: G11B5/54
Filed: 1966-04-01
Abstract: 1,147,611. Recording and playback. A. L. TRIMINGHAM. 1 April, 1966, No. 14621/66. Heading G5R. In a record playback system a flexible record carrier remains permanently coiled on a single spool and a pick up head is movable across the spool and also parallel with the axis thereof, so that it may be inserted between turns at different radial distances to select any desired part of the record carrier. The spool 2, which is manually rotatable incorporates a number of upstanding arcuate support plates 4 mounted on a base disc 3, the plates having gaps at 11. A magnetic tape 5 is spirally wound on the spool and is held in position in layers against the support plates by flexible hoops 12 or other spring arrangements which allow the tape to bulge as it passes the pick up head 8. The tape is fixed in position by locating pins which pass through the tape and hoops to prevent displacement. Instead of hoops solid spacers may be used which have a gap in line with the pick up head and which stay stationary as the spool rotates. Where these solid spacers are used, the coils of tape at different radii on the spool are not linked together. The pick up head 8 is suspended from a gantry 6 and is movable vertically so that it can be inserted manually or automatically where required into the turns of the tape. To facilitate this, it may have at its entry end a special probe which, aided by an air jet, separates adjacent tape layers to permit the head to enter. The head may be supported in various positions and may be designed to rotate around the spool axis, the spool and tape remaining stationary. The tape may be multiple track and co-operate with an equivalent number of heads. A number of similar record/playback arrangements may be horizontally or vertically disposed on a common axis, for use in a juke box.

IPC: G06G7/22
Filed: 1959-04-29
Abstract: 877,774. Electric analogue computers. DECCA RECORD CO. Ltd. April 28, 1960 [April 29, 1959], No. 14662/59. Class 37. A circuit for deriving the modulus A of a pair of D.C. signals of amplitudes X, Y representing the rectangular co-ordinates of a point, comprises a chopping switch 14 which converts the inputs X, Y at 10, 11 into A.C. signals which are then filtered, phase shifted by 45 degrees in opposite directions by circuits 22, 23, and the quadrature signals so produced added in a transformer primary 30, so that the reading on meter 34 will represent the required modulus. This result is achieved since X, Y can be regarded as components A sin #, A cos # respectively.of a signal, these are then converted into A A signals - sin #t sin #, - sin #t cos # by the 2 2 switch 14 and phase shifted to give a signal A A A - sin #t cos # + - cos #t sin 6 = - sin (#t + 0) 2 2 2 so that the amplitude of the resultant signal in transformer secondary 32 is proportional to A. The switch 14 is an A.C. relay.

Title: Lubricant mist producing device
IPC: F16N7/34
Filed: 1958-05-07
Abstract: 870,632. Lubrication. AUTO RESEARCH CORPORATION. May 7, 1958 [May 8, 1957] No. 14677/58. Class 12 (3). In a mist lubrication device a compressed gaseous fluid, e.g. air, fed on to a dehumidifying baffle 15 and through a cylindrical filter J in an air chamber C clamped to 'the head B of a lubrication unit A is led to a passage 41 leading through a constant pressure regulator 43, 46 adjustable by a hand screw N, to a chamber 62 which communicates, through passages 63, 64, Fig. 6, with a peripheral groove 65 in a solenoid value R operable by the machine being lubricated. When the solenoid is energized the compressed - air passes through the solenoid valve 69, 70 and passages 76, 77 in the valve housing to a passage 80 in the head B leading to a peripheral groove 81 in, and a converging annular passage 92 around, the nozzle 90 of an aspirator P. Emission of compressed-air from an outlet 93 in the aspirator induces oil, supplied from a passage 148 to a central passage 151 in the nozzle P, to mix with the discharged air to form a heavy oil mist in the inlet portion X of a chamber 94. The air pressure in the chamber 94 is applied to the oil in a reservoir D secured to the lubricator head B to force oil through a cylindrical filter K and up through a central bore 127 in a rod 117 to an adjustable needle valve Q. The oil then passes to a sight feed unit M and on to the passage 148 leading to the aspirator P. Undesirable heavy oil particles are removed from the mist by a collector baffle S in the compartment 94, the mist being delivered to a lubricating line through an outlet adaptor 95. A pressure gauge L communicates with the chamber 62. In a modification, Fig. 10, the collector S has a transversely upwardly-bowed condensate gutter 203 having a central opening 206 to receive the rod 117. In a further modification, Fig. 13, the collector comprises a pivotally mounted double plate 250, the upper section 251, having an opening 254 for the tube 117, being pressed downwardly against a coil spring 25 by an adjustable screw 262. The collector plates shown are solid, they may however be made of perforate metal, or vary fine wire mesh screening.
Patent GB-649295-A (GB)
Title: Improvements in and relating to the manufacture of nitrocellulose
Inventor: EDWARDS HAROLD DOUGLAS
IPC: C08B5/02
Filed: 1948-05-31
Abstract: In the manufacture of nitro-cellulose a part of the residual acid is separated from the pulp resulting from the nitration of cellulose, for example by mechanical means, and the pulp is thereafter drowned in a solution of sulphuric and/or nitric acids, the total acid concentration of which is not less than 25 per cent by weight, provided that in the case of mixed acids the proportion of sulphuric acid to nitric acid is not greater than 2 : 1, the quantity and acid concentration of the immersion solution being such that the total concentration of acids present in the solution after it has been admixed with the pulp does not exceed 60 per cent by weight and is preferably 35-40 per cent by weight.  When sulphuric acid is used alone its concentration in the immersion solution prior to the drowning of the pulp is preferably not over 40 per cent by weight. The temperature of the immersion solution may not exceed 20 DEG  C. and may be kept below this temperature, e.g. 10-15 DEG  C., by passing it over refrigerated brine cooling coils before the immersion operation.  After the pulp has been drowned the immersion solution is removed from the pulp and the latter is sprayed with water to remove the remaining acid.  The resultant washings may be used for making up further batches of immersion solutions.  The separated acid solution may be used again for further immersion operations until the acid concentration reaches the permissible upper limit, at which point the solution wholly or in part may be either diluted and thereafter used in further immersion operations, or may be concentrated.  In an example, 50 lbs. of nitrated cotton linters, centrifuged until the pulp retains 30 lbs. of nitric acid and 42 lbs. of sulphuric acid, is drowned in 3000 lbs. of an aqueous solution containing 21.5 per cent of sulphuric acid and 12.3 per cent of nitric acid and the mixture is stirred.  The pulp is again centrifuged until it contains 5 lbs. of nitric acid and 5 lbs. of sulphuric acid, sprayed in the centrifuge with 20 lbs. of a 10 per cent solution of nitric acid and discharged from the centrifuge into an excess of water.  The quantity of solution separated from the pulp (prior to its being washed) is 3060 lbs. containing 22.3 per cent of sulphuric acid and 12.9 per cent of nitric acid. After the addition of water to restore the original concentration, all but 60 lbs. of the solution is recirculated.  It is stated that the process avoids the production of large volumes of very dilute mixed acids and that denitration of the nitrocellulose due to the generation of heat during the removal of the residual acids from the pulp is prevented.

Title: Improvements in and relating to cop winding machines
IPC: B65H54/14
Filed: 1949-06-01
Abstract: 683,287. Winding yarn. MACKIE & SONS, Ltd., J., and MACKIE, J. P. June 1, 1950 [June 1, 1949], No. 14751/49. Class 120(ii) In a cop-winding machine having a driven winding spindle cop-forming means which define a tapering space round the spindle and yarn - traversing means which lay the yarn in overlapping coils in the said space, the cop-forming means and the yarn-traversing means are moved along the spindle in such manner that the cop is progressively built away from the escape end of the spindle. The spindle 10, of square crosssection, tapers towards its lower end and is driven by a pulley 14; a loose pulley 16 being also provided. The cop is formed on the spindle by cones 18 (not shown), 20, 22, the latter being a traverse cone, attached to a yoke 28 mounted to slide upon a pair of pillars 30 (not shown), and counterweighted at 32. The yarn from supply is led through a tension device 38 comprising a pair of members 110 having pins 112 extending therefrom in staggered relationship and spring-urged at 114 so that the yarn follows a tortuous path. The device 38 is also carried by the yoke 28 and moves with it. The lower end of the spindle takes into a tapered hole in a steady 42 mounted to rotate in ball bearings in a bracket 44 pivotally mounted at 46 and maintained in operative position by a roller 50 on a spring-urged rod 52 engaging a notch in the bracket 44. When the cop has reached the desired size, an adjustable rod 82 trips a spring-pressed lever 66, carried by the upwardly-moving yoke 28, and moves it within the range of a doffing lever 76 which, in its downward motion strips the cop off the spindle by way of the yoke 28 and the cop-forming cones 20, 22. During the stripping of the cop, a roller on the lever 66 contacts the pivoted rod 52 and swings it outwardly against the force of the spring 56 so that the roller 50 is removed from the notch in the bracket 44 allowing the steady 42 to swing, by gravity, clear of the spindle-end. At the same time a pivoted bracket 92 carrying threadsevering blades 98 is swung to the dotted position, Fig. 6. The stripped cop passes down through a fixed tube 100 into a tray 102, the yarn 103 extending through the blades 98. When the doffing lever 76 moves upwardly, the levers 66, 52 are reset' by their springs and the steady 42 swings back to engage the spindle point and is again driven by it. The yarn 103 is then picked up by one of two wings 104 on the steady 42 and begins to wind itself on the spindle, the tautened yarn 103 being severed by contact with the blades 98 which have swung from the dotted position of Fig. 6. It may be arranged that the spindle 10 is stopped from rotation during cop-doffing by removing the belt 12 to the pulley 16. Specification 683,315 is referred to.
