Title: Improvements in and relating to commutating alternating current dynamo electric machines
IPC: H02K27/18
Filed: 1928-11-16
Abstract: 300,616. British Thomson-Houston Go., Ltd., (Assignees of Compagnie Francaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). Nov. 16, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Alternating-current commutator machines: rotary transformers.-To improve the commutation of an alternating-current commutator machine, the reluctance of the air-gap is increased at the commutating zones. Fig. 2 shows a longer air gap at a commutating zone, and since the stator is uniformlv wound, the reduced depth of the slots is compensated by shallower wedges. The invention is particularly applicable to machines of the type shown in Fig. 1, comprising separate or combined primary and commutator windings A, B which machines can operate as motors, generators or frequency changers or as frequency changers combined with motors or generators. For motor operation the stator windings S, - - S3 are connected to the commutator brushes b1 - - b3 directly or through a tapped transformer. At speeds near synchronism, the transformer is not employed, and at synchronism, the windings S1 - - S3 are shortcircuited. When the machine operates as a frequency changer, the primary winding may be supplied through a tapped transformer or an induction regulator, and the windings S1 - - S3 are connected directly to the commutator brushes. In the case of a three phase secondary winding, the pitch of the commutator winding equals two thirds of the pole pitch and there are three commutation zones per pair of poles. Specification 235,917 is referred to.

Title: Production of vat dye
IPC: C09B3/00
Filed: 1921-12-14
Abstract: Dibenzanthrone is obtained in a purified condition by subjecting the crude product of alkali fusion of benzanthrone to vatting with sodium hydrosulphite, separating the dissolved leuco compound from the insoluble residue, and reoxidizing by air.  It may be further purified by extraction with dichlorbenzene.  The alkali fusion may be effected in the presence of an inert diluent, for example kerosene, and an organic reducing-agent, for example dextrin.  The purified dibenzanthone gives a green dye on nitration, while the insoluble by-product gives a grey nitration product.  Specifications 16538/04 and 126,765 are referred to.

Title: Improvements in or relating to suppressors more particularly for sparking plugs
IPC: H01T13/05
Filed: 1957-10-30
Abstract: 832,022. Sparking plugs; ignition systems. BOSCH G.m.b.H., R. Oct. 30, 1957 [Nov. 3, 1956; Sept. 20, 1957], No. 33806/57. Class 7(4) [Also in Group XXXVI] A suppressor has a casing 1 of insulating material with a recess 2 for receiving the end of an ignition cable which is secured by a pointed screw 3 having a knurled head 7. A bush 5 for attachment to a sparking plug is secured in recess 4, the suppressor resistor being wound on a support 6. The current-conducting parts of the resistor are intimately embedded in a sheath 8 of thermosetting'synthetic resin to prevent corona discharge. The resistance coil is secured by a metal cap 6<SP>1</SP> which is fixed to an attachment on the head 7. Turns of the resistance, wire are wound between the convolutions of helical spring 9 which establishes electrical contact with the plug-bush 5. The section of the support 6 carrying the spring is stepped so that the sheath 8 has substantially the same thickness throughout its length. The section of the casing enclosing the sparking plug is coated internally with a layer 11 of polyester resin to prevent leakage currents. A suitable synthetic resin for the sheath 8 consists of a mixture of polyester resin with a suspension agent and a hardener such as benzoyl peroxide. In another arrangement, the resistor has two metal terminal caps and is inserted into a prefabricated casing of insulating material, synthetic resin being injected into the space between the inner wall of the casing and the resistor, so that the casing locates, without an intervening gap, the sheath within which the resistor is embedded, Fig. 2 (not shown). A mixture of a polyester resin with kaolin, with an admixture of a catalyst, is suitable for this purpose. The casing 1 may be moulded directly around the suppressor resistor, an alkyd resin powder being suitable, Fig. 3 (not shown). A metal casing 12 enclosing the sparking plug is provided with a spring washer 13.

Title: Arrangement for checking the battery voltage of an electrically driven cinematographcamera
IPC: G01R31/36
Filed: 1961-09-21
Abstract: 983, 307. Photo-electric exposure control; electric battery tests. K. VOCKENHUBER. Sept. 21, 1961 [Sept. 23, 1960], No. 33808/61. Headings G1A and G1U. [Also in Division H2] In a battery operated kinematograph camera having an exposure control of the type in which a resistor in a photo-cell circuit takes account of frame speed changes, the resistor is retained in circuit with the galvanometer when the latter is used to check the battery voltage. The camera motor 7 is fed from the battery 9 in circuit with a shortable resistor 11 to vary the frame speed. The switch 10 is ganged with a switch 5 which connects a resistor 6 in parallel with the exposure meter 1 to allow for the change in frame speed. The battery voltage is checked by closing switches 13, 14 and masking the photo-cell so that it provides a high resistance shunt to the meter. Since approximately double the battery voltage is required to operate motor 7 at double the speed, the presence of resistor 6 results in the pointer of meter 1 always registering with the same mark when the battery voltage is satisfactory. Further slight correction may be made by varying resistor 12 on operation of switches 5 and 10. The mask may be combined with an operating member for switches 13, 14, Figs. 3 and 4, (not shown) so that the latter cannot be operated unless the former is in place.

Title: Improvements in or relating to magnetic devices
Inventor: BOWYHARD PETER ISTVAN
IPC: H03K17/84
Filed: 1961-09-22
Abstract: 1,025,354. Thin magnetic film storage elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Sept. 11, 1962 [Sept. 22, 1961], No. 34010/61. Heading H3B. A storage element for a single binary digit comprises two areas 18, 19 of ferromagnetic thin film 10. Each area 18, 19 has two drive windings 13, 14 and 15, 16 respectively, and a digit winding 20 and a sense winding 17 which are perpendicular to the drive windings. Alternatively a single winding may 'serve for both digit and sense purposes. The drive windings are positioned at a small angle, e.g. 3 degrees, to the easy direction of magnetization of the thin film areas so that any relapse of a magnetic vector from the hard to the easy direction takes place in the zero direction except when the digit winding is energized. A binary digit is written into the storage element by applying pulses to the drive windings 13-16 and simultaneously energizing the digit winding in one direction for a binary one and in the other direction for a binary zero. Alternatively the digit winding may be pulsed in the appropriate direction only when a one is to be written. To read out the element, a pulse is applied to the drive windings 13, 14 to rotate the magnetization vector of area 18 to the hard direction. When this pulse terminates, a pulse is applied to drive windings 15, 16 so as to rotate the magnetization vector of area 19, at the same time as area 18 relapses to its zero state. Thus an output pulse is produced at this time in the sense winding only if both vectors are rotating in the same direction, i.e. if a one is stored. The drive pulses for windings 15, 16 may be produced by differentiating the trailing edge of the drive pulses for windings 13, 14 and then inverting. The output may include a gate 26. These elements are used in a storage matrix, Fig. 5 (not shown), which may be three-dimensional. The storage elements may also be used as logical elements. Tolerance of the various pulses may be increased by using bias current.
