Abstract: 323,875. Miller, L., Brooks, R., and Associated Electrical Industries) Ltd. Nov. 27, 1928. Controlling motors by varying terminal voltage. - The working motor is started and controlled with the aid of a motor-generator set. In the first stage the working motor takes current solely from the motor-generator set; at a later stage the motor-generator is in series opposition to the mains feeding the working motor; in the third stage the motor-generator adds its voltage to that of the mains. The arrangement, shown in Fig. 1, includes the working motor armature 6, its field 7, the armature 12 of the motor element of the set, its field 13, the armature 14 of the generator element of the set, its shunt field 15 connected across a potentiometer resistance. 15<a>, and its series field 16. Between the first stage and the second stage a resistance 22 is made use of to effect smooth transition by connecting it between the working motor and the mains while the generator connections are being changed at the switches 17, 18. Transition from the second to the third stage is effected by gradually operating the potentiometer rheostat. A relay 27 is arranged to weaken and strengthen the motor field 7 according to the load. Specification 326,134 is referred to.

Title: Improvements in or relating to open-air high-tension switches
IPC: H01H33/02
Filed: 1929-11-15
Abstract: 343,546. Measuring transformers. KOCH & STERZEL AKT.-GES., 40, Zwickauer Strasse, Dresden, Germany. Nov. 15, 1929, No. 35031. Convention date, Nov. 29, 1928.

Title: Improvements in or relating to electron beam tubes
IPC: H01J29/88
Filed: 1956-11-16
Abstract: 816,452. Cathode ray tubes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Nov. 16, 1956 [Nov. 25, 1955], No. 35099/56. Class 39(1). In a cathode ray receiving tube surfaces liable to be struck at grazing incidence by electrons of the beam, i.e. at the junction between the tube neck and flared portion, in wide angle deflection tubes, are coated with an element or mixture of high atomic number or high average atomic number such as Ag, Au, or Mo, (high means >25 as opposed to graphite whose atomic number is 12); the emission of low velocity secondaries (energy up to 50 e v) from such a surface particularly for grazing incidence is less than that (60 degrees or more to the normal) for graphite so that fewer positive and negative ions are generated by collision between secondaries and residual gas molecules and consequently the screen and other parts of the tube are not subjected to such heavy ion bombardment. The remainder of the inner wall of the envelope except the face plate has a conductive coating, e.g. of silver in contact with the first conductive coating and an atomic number of L25. While more high velocity scattered electrons are generated than for graphite, these are not so effective in producing positive and negative ions by collision and those ions which are produced are more diffuse. If the deflection angle of the tube is less than 90 degrees, as shown, the high atomic number coating does not have to extend into the flared part of the envelope, only a small part of the neck at the end adjacent the flared portion is therefore coated. The coating can be replaced by an annular insert. The positive ion bombardment (e.g. of H,O ions) of a non-aluminised screen causes an "X burn " i.e. a cross at the centre whose arms extend along the picture diagonally. Secondary emission from a non-aluminised fluorescent screen and the share charge thereof causes the screen potential (originally equal to cooling potential) to drop by a few hundred volts thus causing an accelerating and focusing field between coating and screen for the positive ions, the focusing action producing the sharp cross. In the form shown a silver coating 24 is in conductive contact with graphite coating 26 on either side thereof, the graphite being put on in an aqueous suspension ; potential is applied to the coatings through a bulb terminal and, vice contact springs 28, to the gunanode. The deflection angle can be 90 degrees in which case the high atomic number coating extends from A to B (the flared part of the envelope being of rectangular cross section) In manufacture the coating material together with a binder of methyl methacrylate or nitrocellulose is painted on the required surface the binder being decomposed or removed in subsequent bobing and degassing. The surface of the coating can be roughened to reduce the secondary emissivity still further by embedding particles of high atomic number material in the surface by sintering or by sand blasting a smooth surface, or by evaporation of metal in an inert atmosphere.
