Title: Vibrating rotor gyroscopes
IPC: G01C19/30
Filed: 1966-06-30
Abstract: 1,101,258. Gyroscopic apparatus and pick-off for use therewith. LITTON INDUSTRIES Inc. June 30, 1966 [July 7, 1965], No. 29531/66. Headings G1C and G1N. A vibrating rotor gyroscope comprises an inertial rotor ring element 26 mounted for rotation about a spin shaft 20 and by means of a pair of opposed torsion bars, 28 (only one shown), for vibratory motion about an axis normal to the shaft 20, and a pick-off for the vibratory motion of the element 26 including a permanent magnet 34 whose magnetic field passes radially through the element 26 to pairs of coils 42, 42' arranged 180 apart at the periphery of the element 26. A hysteresis motor 16 is provided to drive the shaft 20 which is solid with a thrust bearing pad 24 and sleeve 25 mounted in a gas spin bearing 22. An umbrellashaped member 21 rotates with the shaft 20 and this carries a toroidal rotating housing 32, which is evacuated or contains a low density atmosphere, and in which the ring element 26 is mounted, the torsion bars 28 being secured to the element 26 and to supports 30 in the housing 32. The frequency of vibration of the element 26 about the axis defined by the torsion bars 28 is arranged to be the same as that of rotation of the element. The magnetic flux from the magnet 34 is coupled through a polecap 36 and a ferrite ring 38 to the element 26 and from thence through a ferrite coil support member 44 and by way of an outer casing member 12 to the magnet. In order that energy losses between the element 26 and pick-off coils be kept to a minimum the outer portion 40 of the housing 32 is made of a non-magnetic and non-conducting material. The sides 33 of the housing 32 are of ferromagnetic material and one of these sides includes a ceramic ring 35 to prevent currents being developed from the motion between the pole-cap 35 and housing 32. When the gyroscope is subjected to angular displacement about an axis which is not that of the shaft 20 the element 26 will execute torsional vibrations about the axis of the bars 28 the maximum amplitude of these vibrations being proportional to the displacement. The two pairs of pick-off coils 42, 42' are all connected in series and the vibrations of the element 26 will generate a voltage across each of these coils of a frequency twice that of the torsional vibrations and these voltages will be additive since the coils are in series. Signals caused by spurious vibrations of the element will be eliminated, i.e. movements of the element 26 as a whole parallel to the shaft 20 will generate opposing voltages in the coils of each pair, and movements normal to the shaft 20 will generate opposing voltages in the pairs of coils 42 and 42'. Single coils may be used in place of the pairs 42, 42' if the effect of these spurious signals is unimportant. Also, the coils may be used as torque coils if desired and additional torque coils may also be provided spaced 90 from the coils 42, 42'.

Title: Improvements in the treatment of threads and the like with liquids
IPC: D01D5/04
Filed: 1931-10-26
Abstract: <PICT:0391443/IV/1> <PICT:0391443/IV/2> <PICT:0391443/IV/3> <PICT:0391443/IV/4> In the dry spinning of artificial filaments, yarns, &c., in particular of cellulose acetate, liquid is applied to the filaments &c. during their drying, especially during the early part of their travel, by means of a freely-mounted roller or other rotatable device irrigated or fed with liquid.  The roller 9 is preferably made of light material such as aluminium, resins &c., and it may be provided with grooves 28, Figs. 3 and 6, which guide the filaments and may be proportioned to control the amount of liquid supplied to them.  Liquid may be supplied by means of a wick 10, Fig. 1, or by means of a bath 24, Fig. 5, into which the roller dips, or by means of a feed device delivering to the upper part or rising side of the roller.  The roller may be provided with means for retarding its motion, for example, with a friction device, or with vanes 20, Fig. 3, which act as an air brake or are arranged to dip into liquid 21 or to be acted on by an air jet; or the retarding devices described in Specification 329,620, [Class 2 (ii), Cellulose &c.], may be employed.  The liquids to be used may be any of those mentioned in Specifications 327,740, [Class 2 (ii), Cellulose &c.], and 355,652 for varying the lustre and other properties of the filaments, or they may be adapted to soften the filaments preparatory to a stretching operation as is described in Specification 342,712; and for such latter use it is preferred that the rotation of the roller shall be retarded as in the manner above referred to in order to prevent the stretch extending back to the spinning nozzle, further devices to this end being the placing of the roller to the side of the spinning cabinet and the lapping of the filaments round the roller.  When stretching it is convenient to employ a drawing roller of conical form, the narrower end being used when starting and the filaments being subsequently transferred to the larger diameter.

Title: Improvements in power transmission clutches
IPC: F16D23/06
Filed: 1933-05-31
Abstract: 402,723. Claw clutches; facilitating change of speed. JENKINS, H. G., Leigh Vicarage, Sherborne, Dorset. May 31, 1933, No. 30006. Divided on 401,447. [Class 80 (ii).] In a claw clutch, particularly for use in conjunction with the tail shaft 2 of a motor-vehicle gear-box, pawls 24 are pivoted on pins 63 carried by a ring 61 feathered on the driving member 3, carried by the shaft 2. One end of the pawls cooperate with steps 29 and slots 26 formed on the member 3, while the other end is fulcrumed in recessed members 67 which are rotatablymounted and radially-movable in a member 20, journalled on the member 3 and provided with a conical surface 21 adapted to engage frictionally with a conical surface 22 on the driven member 6 during the clutch-engaging movement of the latter. When the speeds of the members 3, 6 differ, the pawls tilt relative to the shaft axis so as to engage the steps 29 and thus prevent clutch engagement, whilst on the occurrence of synchronism the pawls return into parallel relation with the shaft axis and enter the slots 26, thus permitting clutch engagement. V- shaped recesses 68 in the member 20 limit the tilting of the pawls. The ring 61 is urged towards the member 6 by a spring 70, such movement being limited by coacting conical faces 69 on the members 3, 20. The movable member 6, splined on its shaft 7, is controlled by a fork 15 which is coupled to the main clutch pedal 18 by a rod 40 and a manually-controlled pivoted latch 47. A spring 36 tends to move the member 6 towards the member 3. Thus, with the latch 47 in effective position, the claw clutch is disengaged simultaneously with the main clutch and, on release of the pedal 18, is re-engaged by the action of the spring when synchronism occurs. By moving the latch 47 into ineffective position by Bowden mechanism 50, the connection between the fork 15 and the pedal 18 is disestablished. Specification 331,346, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to.

Abstract: 633,075. Weighing-apparatus. TRACY, G. M. Oct. 8, 1946, No. 30051. [Class 143] A float balance for weighing-out p r edetermined quantities of material has the float pre-loaded and submerged to a subnormal depth so that downward movement of the float does not occur until the predetermined weight is reached. As shown, a weigh-pan 34 is supported by a bar 20 guided for vertical movement by antifriction rollers 22, 23 on a standard 24 within a liquid-filled tank 10. A pair of cylindrical floats 17 are disposed on either side of the bar 20, and each has a hook 18 at its lower end engaged with either end of a transverse rod 19 carried by the bar 20. Stop pins 29 projecting from the standard 24 engage over the rod 19 to hold the floats down at a fixed level below their free floating level. The tank is fitted with a liquid level gauge 16, a filling opening 13 and a drain cock 15 so that the level can be adjusted according to the required weight which is shown directly in pounds on the gauge 16. Small adjustments in level are made by a variably immersed member 35 vertically adjustable by a screw 36 fitted with a knob 37 graduated in ounces. When the pan has been loaded up to the weight set on the gauge 16 and knob 37, the floating system moves downwards slightly and this is shown by a contact 42 carried by the bar 20 bridging mercury cups 44 in the circuit of an indicator. Alternatively an automatic device may operate to discharge the weighpan.
