Title: Improvements in or relating to power transmission mechanism
IPC: F16D23/04
Filed: 1929-06-28
Abstract: 329,556. Royce, F. H. June 28, 1929. Right to Patent relinquished. Facilitating changing speed.- Relates to means for effecting reversed driving through a vehicle change-speed gear isolating clutch of the kind comprising a baulk ring c<2>, Fig. 2, for preventing claw members c<1>, d<1> from re-engaging until synchronization, as described in Specification 306,636. Means operable by the driver for permitting reengagement of the clutch members c<1>, d<2> by the spring are operably connected to the reversegear control mechanism, so that on reverse gear a drive through the clutch is possible. The baulk ring c<2> is loose upon the sleeve c having clutch end c', and sleeve c is fast on shaft l leading from the gear box. Shaft l<1> reads to the differential. Upon splines e on the baulk line ring c<2> there slides a sleeve f with cams f<1> on its ends adapted to co-operate with lugs f<2> upon driven claw clutch member d<1> so as to render the baulk ring inoperative and allow free engagement of the claw clutch. Ring f is connected by a fork b<1>, Fig. 1, to the selector rod a<4> which carries the reverse-gear striking-fork b. Prior to change, main clutch pedal is depressed and, through rod h<2>, disengages the isolating clutch, rendering the baulk ring operative. Moving control lever a to engage the reverse gear renders the baulk ring inoperative so that on release of pedal j, spring k<3> engages the isolating clutch and reversed driving becomes operative.

Title: Improvements in or relating to textile spinning machines
IPC: D01H1/30
Filed: 1955-07-11
Abstract: 803,590. Textile spinning machines. SAGEHOMME, E. M. July 11, 1955 [July 14, 1954; Nov. 12, 1954], No. 19989/55. Addition to 724,122. Classes 120(2) and 120(3). A spinning frame as described in parent Specification is provided with an indicator panel and two pointers movable over it at right angles to one another in such manner that the intersection of the pointers indicates on lines inscribed on the panel the twist imparted to the yarn at the settings of the frame represented by the pointer positions. A further panel may also be provided with pointers which, when related to inscribed curves, indicate suitable draft and package building conditions. The first panel 54 has pointers 56, 57 attached to bands 60, 63 that pass around pulleys 61, 66. Pulley 61 is connected by a flexible shaft 62 to the handwheel 45 by which the electric motor 20, and consequently the speed of the spindle 4, is controlled. Pulley 66 is connected to the handwheel 46 controlling the motor 24 and adjustment of either the pulley or the handwheel varies the motor speed with resulting changes in the speed of the delivery roller 2 and of take-up through the electronically controlled motor 21. Since spindle and take-up speeds affect twist, the panel 54, which may be of transparent material, may be inscribed with lines indicating twist values so that when, during the working of the frame, the spindle or production speeds are adjusted, the position of intersection of the pointers 56, 57 will indicate the amount of twist. Alternatively, by making the intersection of the pointers 56, 57 follow a desired twist line, adjustments to the frame may be made. The panel 55 has one of its pointers 58 connected to the handwheel 49 by which the speed of feed roller 2 is determined and by adjustment of which the draft can be varied, and the other pointer 59 is connected through the pulley 73 with the handwheel 51 by which the building traverse is controlled and the handwheel 53 that controls the building lift. The connection with handwheel 53 may be broken when necessary for independent adjustment of the building lift. By suitable positioning of the pointers 58, 59 desirable relationships are said to be possible between the count of the yarn and the pitch of the yarn laid on the package.

[Also in Division H1] A radio goniometer of the type described in the parent Specification 944,861 comprises a rotor (IR), Figs. 3 and 4 (not shown) provided with two similar windings (W1,), (W2) substantially at right angles to one another. Each winding has two winding parts, one of which is wound on one side of the rotor axis and the other on the other side thereof. In a directionfinder incorporating the goniometer, a twinpath receiver is used, the windings (W1) and (W2) being connected respectively to the input terminals of separate amplifiers (C1), (C2), Fig. 5 (not shown), which supply the rectangular co-ordinate deflection systems of a cathoderay tube through further amplifiers (IF1) and (IF2). The stator half windings (1), (1<SP>1</SP>), (2), (2<SP>1</SP>), (3), (3<SP>1</SP>), (4), (4<SP>1</SP>), Fig. 1 (not shown), may be connected to a common point, Fig. 5 (not shown), and by means of ganged switches (S1), (S2) the voltage to earth may be applied through a 90 degrees phase shifter (PS) and an amplifier (PSA) to the control grid of the cathode-ray tube to allow sense determination. In a modification (Fig. 6, not shown) the stator half windings are joined in pairs, each junction being connected to a contact (RS1-4) of a respective relay (RL1-4). The relays are caused to operate by a selector switch (CS) coupled to the goniometer shaft, so that only the output from the stator half windings connected to the pair of aerials whose common plane is most nearly perpendicular to the incoming signal direction is made available for sense determination.

Title: Improvements in and relating to means for exciting alternating current generators
IPC: H02K19/38
Filed: 1925-08-10
Abstract: 250,807. Kirkland, J. W., (Aligemeine Elektricitõts Ges.). Aug. 10, 1925. Exciting; regulation of exciting machines.-Machines, particularly alternating-current generators with high peripheral speeds, have exciters separately driven, and in addition an auxiliary exciter coupled directly or indirectly to the main machine shaft. The auxiliary machine H is smaller than the main exciter E but has such an output that by means of the continuous current taken from it to excite the main generator, the current for driving the main exciting set may be taken from the main generator. The starting of the main exciting set may be effected from the continuous-current side. The auxiliary exciter H only supplies current until the main exciter set E is started and operated from the alternating current system of the main machine G, the change-over being effected automatically. The auxiliary machine may be used for the separate excitation of the main exciter and the regulation effected by varying the field of the auxiliary machine. An induction motor M with a squirrelcage rotor is preferably used to drive the main exciter E and it may also drive a fan or pump for the cooling of the alternating-current generator.
