Abstract: 355,071. Induction motors. SWENDSEN, J. W., 9. Klingenberggaten, Oslo, Norway. Sept. 18, 1930, No. 27928. Convention date, Sept. 19, 1929. Addition to 339,206, [Class 35, Dynamo-electric generators &c.]. [Class 35.] In an induction motor as in the parent Specification comprising one or more ring-shaped stators and a rotor consisting of two or more ring-shaped magnetic elements, the short-circuited bars for each pair of rotor elements adjacent to one stator consists of U-shaped bars with one limb of each passing through one of the rotor elements so that the ends project outside the periphery of the rotor elements where they are joined by means of shortcircuiting rings. The stator 11 is secured to the frame 13 by legs 12 and has a ring-winding 14. The rotors 17,18 are slotted to receive the U-shaped bars 28, the ends of which are welded or otherwise secured to short-circuiting rings 31, 32. The rings are spaced away from the cores to ensure adequate cooling. Shields 33, 34, preferably divided into halves, may be screwed to the short-circuiting rings to reduce flux leakage. The stator and rotor cores are formed by winding a strip of metal into a coil.

Abstract: 1,064,250. Electric selective signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. July 2, 1965 [July 9, 1964], No. 28071/65. Heading G4H. [Also in Division H3] Data is transmitted in constant ratio code as two frequencies, one from each of two groups of four. The receiver separates the frequencies and checks that there is present only one frequency from both groups, and that the frequencies have lasted longer than a preset time. The code-checking circuit, which is transistorized, Fig. 3 (not shown), controls gates which pass to a register the signal from a code recognition circuit fed by the eight channels, and also prevents the receiver from responding to any further code.

Title: Improvements in and relating to vibratory converters
IPC: H02M7/62
Filed: 1946-09-20
Abstract: 616,669. Converting. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 20, 1946, No. 28200. Convention date, Sept. 21, 1945. [Class 38 (ii)] In a converting system in which a vibratory interrupter periodically reverses the current in a winding with a magnetic core, immediately before the winding receives its first operating impulse which would produce flux in one direction, the core is magnetized in the other direction, to prevent the high starting current occurring when the residual flux is in the first direction. When the D.C. input is connected to the upper contact of switch 11, to set the reed 8 in vibration, the first current impulse always passes through the upper half of primary 3 of transformer 4 to produce flux in the core in the same direction. By connecting the input to the lower contact 12 of switch 11 immediately before this, current, limited to a suitable value by resistor 13, passes through the lower half of primary to produce flux in the reverse direction. Switch 11 may be arranged so that connection must always be made to contact 12 first, Fig. 5 (not shown).

Title: Improvements in the synchronisation of similar three-phase alternating current supplies
Inventor: TUGWOOD BRIAN RICHARD
IPC: H02P5/50
Filed: 1956-09-14
Abstract: 831,278. Automatic speed control; synchronizing A.C. sources. DE HAVILLAND PROPELLERS Ltd. Nov. 11, 1957 [Sept. 14, 1956], No. 28201/56. Class 38 (4). In an arrangement for synchronizing master and slave three-phase generators by applying their frequency difference as detected by rectifiers W1, W2, W3, Fig. 1, through magnetic amplifiers TZ to a synchronous motor which is mechanically coupled to an R.P.M. controller as in Specification 746,080, a multiple of the difference frequency is derived for application to the magnetic amplifier stage. The arrangement of Specification 746,080, Fig. 1, is modified by connecting the slave generator to the rectifier networks W1, W2, W3 through a frequency multiplier M2, Fig. 2, comprising a pair of rotatable three-phase stators Sl, S2 inside which interconnected three-phase rotors R1, R2 are rotated by a frequency or phase comparator M1. The stator S1 is energized by the slave generator and due to the rotation of the comparator shaft the output from stator S2 comprises a signal differing in frequency from the master by twice the slave frequency error for application to rectifiers W1, W2, W3. The cumulative phase error determined by the output of a synchro M3 is applied to a motor M4 to rotate the stators S1, S2 to introduce a phase-restoring integral function. An arrangement wherein an antihunting differentiating function is added to the rotary input to stators S1, S2, is described with reference to Fig. 4 (not shown), the differential being derived by a feedback potentiometer and applied to the stators with the integral function from motor M4 through a differential gear. The use of mechanically coupled synchros as an alternative multiplying arrangement is suggested, and an arrangement wherein a singlephase input is applied to the stator S1 is described with reference to Fig. 3 (not shown). The generators shown are part of an aircraft installation and adjustment is effected by altering the pitch of the propellers. Specification 822,493 also is referred to.

Abstract: 1,018,291. Grinding; copy milling. G.K.N. SCREWS & FASTENERS Ltd. Nov. 1, 1962 [Aug. 5, 1961], No. 28522/61. Headings B3D and B3K. [Also in Division F2] In a cam-controlled milling or grinding machine producing a bi-lobed epitrochoidal curve, e.g. a chamber of a rotary internal combustion engine casing enclosing a generally equilateral triangular-shaped rotor, wherein a rotary cutter (or grinding wheel) of radius L and a easing 3 are relatively rotated about a point O, the relative rotational or linear displacement of the cam and follower is proportional to the angle α of the relative rotational displacement of the cutter and the casing, and the lift of the cam follower determines the distance C of the cutter axis S from the point O. The co-ordinates x and y of a bi-lobed epitrochoidal curve described by a point P are determined by: where e and R are respectively a generator OE turning through 3# about the point O and a generator EP turning in the same sense through # about the point E. The values of C and α are determined from the following expressions deduced from the figure of the Provisional drawing: The cam contour may correspond to α values of 0 to 90 degrees in which case the direction of cam and follower relative movement is reversed at the end of each cycle, or 0 to 180 degrees or 360 degrees in which case said direction is unchanged and the complete epitrochoid is completed in two cycles or one cycle respectively. The cam may be contoured externally or internally. The follower may be a roller or a member which is in sliding contact with the cam and which may or may not be pivoted about a point of support corresponding to the roller axis. In Fig. 1 (Complete) the cam 6 makes two revolutions to one of the casing 3, and the cutter 4 and the roller follower 7 also of radius L are mechanically coupled at 5 so that their radial movements relative to the casing and cam respectively are identical in direction and extent. The cam is cut from a circular blank by a milling cutter which is of radius L and is adjustable radially with respect to the cam axis. In Figs. 3, 4 (not shown) a roller follower of radius L is acted on by a face cam.

The container is then almost filled with liquid and the outlet pipe, which is closed by a mandrel, is inserted through the neck 18 of the container to engage with a socket 28 in the measure. The mandrel is then withdrawn, rearward movement of the pipe 14 being prevented by a projection 32 thereon which also provides an air-tight seal so that in the normal upright position of the container liquid does not rise up the outlet pipe. In modifications, the outlet pipe may be formed with the neck 18 or the container may be of metal and the measure and pipe inserted into the container before the upper or lower ends are closed; the upper end of the outlet pipe is sealed to the container by a plug (34, Fig. 2).
