Title: Improvements relating to alternating electric current phase converters
IPC: H02K47/30
Filed: 1927-05-11
Abstract: 295,068. Schr÷der, E. May 11, 1927. Rotary converters and transformers. - A phase converter, particularly suitable for electric heating and welding currents, consists of a two-phase stator excited by Scottconnected windings from a three-phase system and a secondary winding surrounding one of the stator phases so that current is generated in the secondary winding partly by the action of the totor and partly by ordinary transformer action. In the form shown in Fig. 1, the four stator poles a - - d carry Scott-connected windings having three-phase terminals I, II, III, the two coils on the poles a, c being connected in series and connected in " T " to the junction between the coils b, d. Around the coils on one or both of the poles a, c is a secondary coil s in which single-phase current is induced by direct transformer action and by the action of a rotor t, excited by a continuous-current coil r and running synchronously in the alternating field. A squirrel cage may be combined with the rotor to facilitate starting and tappings may be provided on the windings of the poles a, c to enable the output to be varied. The poles a, c may be divided into two unequal parts with the Scott-windings on the smaller parts and the secondary coils surrounding the complete poles. Figs. 4 and 5 show a form in which the Scottwound poles a- - d are supported in a frame f around and parallel to a shaft w carrying a rotor consisting of poles co-operating with both ends of the stator poles. The secondary winding consists of a single turn s which may be made integrally with the stationary centre part g of the frame.

Title: Improved retarded or delayed action electric motor controller or switching device
IPC: H01H7/02
Filed: 1937-05-04
Abstract: 495,257. Actuating controllers. MORRISON & SONS, Ltd., A. E., MORRISON, A. E., and MORRISON, A. C. May 4, 1937, No. 12715. Addition to 469,665. [Class 38 (iii)] The controller described in the parent Specification is modified in that the main operating member acts directly on a pressure unit 26, controlled by a spring 34 which resists movement, and a spring 32 is associated with the unit 26 and the actuating member 1 to couple these parts together yieldably. Thus when the operating member is moved by a small amount of pressure the actuating member is operated slowly, but upon the application of greater pressure the actuating member is moved at the maximum speed permitted by the retarding means 11. Upon depression of a pedal the unit 26 is raised against the spring 34, and the compression spring 32, positioned between a lower collar 28 of the unit 26 and a ring 30 shrunk on to the actuating spindle 1, is effective to operate the contacts carried by a block 40 over contacts 43, 46. When the pedal is released the spring 34 returns the actuating spindle to its off position. The unit 26 may be operated by a coil controlled by the operator. The retarding means may be in form of a fan or a vacuum or oil type dash-pot.

Abstract: 700,504. Temperature-responsive actuating elements. PYRENE CO., Ltd. May 23, 1951 [May 23, 1950], No. 12903/50. Class 64(2) [Also in Groups XXIX and XXXVII] Apparatus for detecting sharp rises of temperature in aircraft engines and constituting an improvement in the device disclosed in Specification 644,172, [Group XXXVII], comprises a fire detector tube 8 connected through passages 10, 14 to a Bourdon contact-operating tube 16, and through the passage 10 and a narrow annular passage 48, forming a restriction, to a distensible chamber 36. The passage 48 is formed between a central bore in a member 44 and a plug 46 of slightly less diameter, the chamber 36 being formed between a bellows 40 and a rigid wall 38, and the tubes 8, 16 and chamber 36 being filled with a liquid silicone. To prevent damage to the tube 16 due to excessive liquid pressures, the plug 46 is secured to a movable cross-bar 50 controlled by a spring 52 whereby valves 54 controlling passages 55 open to by-pass part of the passage 48. Further pressure rise causes the plug 46 to uncover ports 57 leading to the passages 55. The Bourdon tube 16 has an arm 18 carrying a striker 22 which moves a contact-carrying spring 24 to engage a contact 28 upon a sudden rise of temperature adjacent the tube 8. For a gradual rise in temperature the liquid bleeds through the passage 48 into the chamber 36 and the contacts 24, 28 are not operated. Inadvertent operation due to vibration is prevented by a spring 20 on the arm .18 engaging an adjustable eccentric stop 35. The member 44 is formed of steel and the plug 46 of brass the higher coefficient of expansion of the brass ensuring that increase of ambient temperature causes a diminution of the passage 48 to compensate for the corresponding decrease in viscosity of the liquid. Rapid resetting of the apparatus is ensured by a non-return valve 58 in the member 44 permitting flow of liquid back to the passage 10. A liquidfilled chamber 62 connected by a pipe 60 to the passage 14 may be compressed by a button 64 to test the apparatus. According to the Provisional Specification the apparatus may be housed in a flame-proof cover. Specification 600,486, [Group XXXVII]. also is referred to.

Abstract: 593,245. Clutches. MORRIS MOTORS, Ltd., BROWN, T., and THOMAS, W. J. May 25, 1945, No. 13159. [Class 80(ii)] In a variable-speed gearbox a dog clutch h, i between a pinion f slidable on a shaft a and another pinion b rotatable on the shaft includes a sliding sleeve g arranged between and splined to both the pinion f and shaft a. Prior to the engagement of the clutch as shown in Fig. 1 the sleeve g is locked to the pinion f by a ball u, engaging in a hole t in the sleeve and a recess v in the pinion bore, but on continued movement of the sleeve to the left, by a fork engaging the groove w, a friction ring j engages a surface k on the pinion b and the ball u is forced out of the recess v against a spring-loaded plunger p to allow the sleeve to move and engage the dogs h, i as shown in Fig. 2. During this operation the friction ring is additionally loaded by balls n riding out of recesses against springs m, and the end of plunger p which passes through a slot r in the sleeve locks behind a shoulder s in the bore of pinion f. On movement of the sleeve g to the right to disengage the clutch and engage the pinion f with a pinion c on another shaft e, movement of the pinion f is prevented by the plunger p until the dogs h, i are disengaged, the friction clutch j, k released, and the ball u moved by the spring plunger into the recess v in the sleeve. Thus the connection between the pinion f and pinion b is completely broken before the pinion f can be moved with the sleeve to engage the other pinion c.

Abstract: 543,517. Machine guns. VIALE, S. M. Aug. 21, 1940, No. 13310. [Class 92 (ii)] An automatic or semi-automatic gun comprises a striker-housing 11 which is slidable within a breech-block body 10, the sear 14 being pivoted on the body 10 in such a position that, when the striker housing is in its rearward position relative to the body, ' the sear can engage the shoulder 17 of the striker 12 and hold it in cocked position. The housing 11 is closed at the rear end by a slidable abutment 40 for the striker spring 13, the abutment being supported by a hook 41 pivoted at 42 to the body 10. The sear is released by the upward movement of a stirrup 19 suspended thereon, provision being made also for a non-effective relative rocking movement between the stirrup and the sear tail 18. The release movement of the stirrup is effected by a nose 25 on a rotary trigger-controlled rod 24 mounted in the gunstock. If the pull on the trigger be maintained, when the parts move forwards again after the recoil, the toe 26 of the stirrup meets the rear face of the nose 25, and the stirrup is merely rocked rearwardly without any upward release movement being imparted thereto; consequently a second shot is not fired, and the gun can fire single shots only. The upward movement of the stirrup is guided by surfaces 20 on the striker housing.
