Title: Improvements in power-transmission devices, more particularly for diesel locomotives
IPC: H02K49/04
Filed: 1928-03-27
Abstract: 287,878. Magnet-Werk Ges. Eisenach Spezialfabrik f³r Electromagnet- Apparate. March 28, 1927, [Convention date]. Electromagnetic clutches.-In clutch mechanism for Diesel-driven locomotives &c., the work of acceleration is performed by an eddy-current clutch, which is followed in action by an independently - actuated electromagnetic friction clutch, the eddy-current member of the clutch being external, to facilitate cooling. The massive driving-member 2, Fig. 1, carries a friction ring 3 and surrounds a group of pole-pieces 9 on a magnet-structure 5, which is integral with the annular friction-clutch magnet 6 and is secured to the driven shaft 4. The coils 8 and coil 6<a> are independently energized from slip-rings 7, the induction effect being varied by altering the current-strength, number of poles, or pole-pitch, or by a combination of these means. The eddycurrents may be induced in a separate member, and the heat dissipated in electrical resistances. After engagement of the friction clutch, the induction-clutch current is interrupted. The Specification as open to inspection under Sect. 91 (3) (a) comprises also statements that the friction clutch may be other than electromagnetically actuated, and that the heatdissipating resistances may be used for speedregulation, and includes the following modified constructions :-The magnet-structure 5, Fig. 2 (Cancelled), may be divided into parts 5<a>, 5<b> enclosing an annular coil 8 and provided respectively with pole-pieces in the form of spaced fingers 12, 11 projecting alternately to the right and left. The friction-clutch coil 14 is lodged in a recess 13 in the part 5b and is adapted to bring a slidable armature 16 into engagement with a friction ring 18, mounted on a non-magnetic ring 19 secured to the cylindrical part 2<a> of driving- member 2. The parts 2<a>, 19 have cooling-ribs. Fig. 4 (Cancelled) shows a form wherein the eddycurrent member 2b is secured, with interposed copper &c. rings 26, 26<a>, to spiders 20, 20<a>, on which slide the armatures 16, 16<a> of a double friction clutch. The friction-clutch coils 14, 14a are disposed at the ends of the magnet-structure 5, which is formed with arms 5f and a ring 5g, provided with pole-pieces 5h surrounded by the induction-clutch coils 8. Ribs or channels on the friction-clutch members, together with the spideropenings 23, provide for cooling. This subjectmatter does not appear in the Specification as accepted.

Abstract: 214,618. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Johnston, H. H.). April 16, 1923, [Convention date]. Master control systems, electromagnetic.-In a system for controlling a motor from a distant point, starting and accelerating in a forward or reverse direction at will is obtained by a rheostatic controller 4, forward anld reverse contactors actuated by two pairs of windings 17, - - 20, and a relay actuated by a winding 21 when a determinate voltage is applied. Initial movement of the controller 4 to the forward side excludes one section of the resistance 23 and thus applies sufficient voltage to actuate the relay, which switches current to the forward contactors. Contrarv initial movement of the controller leaves in all the resistance, the relay remaining in its original position to switch current to the reverse contactors. After the initial movement either way, electrical interlocks prevent disturbance of the. corresponding setting of the contactors during the subsequent exclusion of resistance for accelerating purposes. The invention is applicable to the control of railway motors bv control current through the rails.

Title: Improvements in or relating to gas compressors and turbines having adjustable statorblades
IPC: F01D17/16
Filed: 1952-04-17
Abstract: 732,788. Axial-flow compressors; turbines. NATIONAL RESEARCH COUNCIL. April 17, 1952 [April 30, 1951], No. 9739/52. Classes 110 (1) and 110 (3). In a gas'turbine plant or a turbine or a compressor forming part of a plant having a combustion chamber in which a plurality of the blades in at least one stage are adjustable, the blades are adjusted by means actuated by differential thermal expansion of parts of the turbine or plant. In the arrangements shown, Fig. 1, a plurality of stator blades 13 are pivoted by means of bosses 17, 18 in the inner and outer casings 11, 12. Rods 19 projecting from the bosses 18 have flattened portions 19a which engage arcuate slots 16 in a tubular member 15 surrounding the casing 11. The tubular member 15 is secured to a flange 14 attached to the combustion chamber casing 10 by a row of pins 15a which extend through a row of elongated holes 15b. The combustion chamber casing 10 is connected to the casing 11 by an expansion joint 20 so that any axial expansion or contraction of the combustion chamber is passed to the member 15 and not to the casing 11. The resulting relative movement between the tubular member 15 and the casing 11 causes the pins. 19 to move in the slots 16 and rotate the vanes 13. The elongated holes 15b allow the tubular member 15 to rotate slightly when the vanes 13 are moved. The arrangement described may be used to adjust any number of stages. Clearance should be allowed between the ends of the stator blades and the casing and the pins 19 and slots 16 to allow for differential expansion. When used to adjust the stator blades of a compressor, the expansion joint 20 is located at the front end of the combustion chamber and the tubular member 15 extends forwardly and surrounds the compressor casing. In the arrangement shown in Fig. 3, the radial expansion of the tube or casing 21 relative to sleeves 29 mounted on a structure unaffected by the heat developed during operation of the turbine, is used to adjust the angle of the stator blades 23. The blades 23 have projecting members 26 with further projections 28 which engage slots 30 in the sleeves 29. To allow for longitudinal expansion of the turbine the sleeves may be mounted on a track running parallel to the axis of the stator. To reduce leakage around the inner end of the blades 23 and the inner casing 22 due to differential expansion, the boss 25 may be increased in diameter. Where this would cause interference between the blades only alternate blades are made adjustable. Reference is made to U.S.A. Specifications 2,219,994, 2,305,311 and 2,428,830.

Title: Improvements in or relating to electric control circuits
Inventor: LLEWELYN ARTHUR IVOR
IPC: G05D3/14
Filed: 1948-04-08
Abstract: 650,894. Automatic control systems. MINISTER OF SUPPLY. April 8, 1948, No. 9850. [Class 38 (iv)] [Also in Group XL (c)] The Figure shows a circuit for preventing excessive hunting in a servo-control system. The apparatus to be controlled is shown symbolically as an indicator 11 which moves about an axis 12. A three phase A.C. supply is connected at terminals 17, 18 and 19 and in the equilibrium position of the indicator 11 as shown, no resultant voltage is induced in the transformer primary winding 20. The first phase of the A.C. supply is thus connected to both the anode and control grid of thyratron 1 so that on positive half cycles of the anode supply the valve fires and after a delay determined by the setting of resistor 7, relay 3 operates. Contact 22 then changes over and connects the second phase of the A.C. supply to the grid of the valve the relay 3 releases and the cycle is repeated. Contacts 26, 27 of relay 3 thus repeatedly reverse the two phase connections to motor 28 which thus oscillates about a mean position at the frequency of operation of relay 3. The position of indicator 11 which is determined by the movement of motor 28 is thus not effectively changed. If the indicator 11 is displaced for example to the left of the equilibrium position the resultant voltage in the transformer winding 21 is in antiphase with the second phase of the A.C. supply so that with the first phase connected to the anode of valve 1 the valve conducts and relay 3 operates. Contacts 26, 27 reverse the motor-phase connections and the motor rotates to restore the indicator to its equilibrium position. The motor continues to rotate until the resultant voltage in winding 21 is not sufficient in the presence of the second phase voltage from potentiometer 24 to cause valve 1 to fire so that relay 3 then releases and the motor slows down. The contact 22 in restoring reconnects the first phase to the potentiometer 24 and disconnects the second phase so that the grid of valve 1 becomes positive during the positive half cycles of the anode, the valve conducts and relay 3 operates. The reversed motor phases are restored by contacts 26 and 27 and the motor drives the indicator towards its equilibrium position. This intermittent action continues until the indicator reaches the equilibrium position when the motor oscillates as described above. Similarly, if the indicator moves to the right of its equilibrium position it is restored by the intermittent operation of the motor as described above. In a modification the voltage from the winding 21 and the first or second phase voltages at potentiometer 24 are applied to separate grids of valve 1.

Abstract: 189,412. Coindet, A. Nov. 25, 1921, [Convention date]. Addition to 156,500. Roller-blinds.-The brake mechanism for blinds described in the parent Specification is modified in that the brake spring 10, seated on the fixed ring 9 on the stationary spindle 5, acts directly upon the member 30 of the two brake members 30, 31, the adjacent faces of which have two interengaging shallow depressions. When the blind is drawn, the rotation of the sleeve 21<1>, which is fixed in the blind roller and carries ratchet teeth engaged by two fixed pawls 40 on a spring pressed ring 41, causes, by virtue of the engagement of the pawls with recesses in the extension 42 of the member 31, the rotation of the member 31, the member 30 being thereby pressed back, as shown in Fig. 3, against the action of the spring 10 which returns the member 30 into its original place when the depressions on the faces of the members 30, 31 allow, the longitudinal movement of the member 30 being effected by a projection 33 on the spindle 5 engaging a helical groove 32 in the bore of the said member 31.
