Abstract: 535,908. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., EARP, C. W., and BYWATERS, G. I. A. Oct. 24, 1939, No. 28600. [Class 40 (v) ] Course indicating signals of the " complementary" type are rectified at N1, passed through a filter R2, R3, C2, C3, and then fed through a valve V1 and transformer T1 which is coupled directly to a meter M of the zero-centre type. The filter cuts out the D.C. component of the signal, together with any undesired high or low frequencies that may tend to make the zero of the meter fluctuate or give an unsteady reading. A closed circuit with a pair of reversed detectors N2 is coupled to the transformer T1 in order to limit the effect of strong signals on the indicator needle.

Title: Azo or anthraquinone dyes containing pyromellitamide groups
Inventor: BRAUN WILLY
IPC: C09B69/00
Filed: 1965-12-31
Abstract: The invention comprises the dyes having the formula <FORM:1060180/C4-C5/1> wherein F represents an azo or anthraquinone dye radical free from sulphonic acid groups and R represents an alkylene or arylene group. The dyes may contain as substituents in F, OH, halogen, NO2, alkyl, aryl, alkoxy, aryloxy and acylamino groups. They may be obtained by reacting one mole of an acid halide of the formula <FORM:1060180/C4-C5/2> wherein Hal represents Cl or Br with at least twice the molar amount of an azo or anthraquinone dye containing a primary amino group but no SO3H groups.  The anthraquinone dyes used as starting materials may be derived from anthraquinone or condensed anthraquinone derivatives such as benzanthrone, dibenzanthrone, isodibenzanthrone, pyrazolanthrone, anthrapyrimidine, anthraquinacridone, pyranthrone, indanthrone, flavanthrone and perylene tetracarboxylic-imide compounds.  Examples are given for the production of dyes in which F is an anthraquinone dye or a condensed anthraquinone dye.  They may be used in pastes, flush pastes, printing inks, distempers, binder colours and lakes, or incorporated in synthetic or natural macromolecular substances, or for mass coloration of fibres of acetyl cellulose, polyacrylonitrile, polyesters, polyurethanes and polyvinyl chloride, or of paper, or for colouring inorganic materials, e.g. cement.

Abstract: 1,146,762. Measuring vapour flow. GULF GENERAL ATOMIC Inc. Dec.13, 1966 [Dec.15, 1965], No.55799/66. Heading G1N. [Also in Divisions C7, G3 and H1] In a system for vapour deposition coating of a continuous strip 13, passing through a vacuum furnace 12, wherein molten material 17 in a crucible is evaporated by an electron gun 18, the vapour flow-rate is monitored and automatically maintained constant by controlling the electron gun. Alternatively the flow-rate signal may be integrated to indicate the thickness of the deposit and switch off the electron gun at a given thickness. Vapour flow monitor Fig. 2 comprises a grid 26 and collector 27 with an ionizing filament 25 in a housing 28 shielding it from X-rays and U.V. radiation to prevent photo-emission. In addition an electrostatic beam stripper 55, to remove charged particles is placed at the inlet and another beam stripper 62 Fig.3, at the outlet to prevent escape of electrons. Automatic control system Fig. 3. For control or measuring purposes a rotary beam chopper 32 is interposed in the vapour flow path to the ion gauge to produce an A.C. signal that can be distinguished from background noise in a synchronous detector 36 gated by pulses generated by the beam chopper, e.g. photo-electrically as shown in Fig. 3, or electromagnetically as illustrated in Fig.4 (not shown). Alternatively the rotary beam chopper may be replaced by an electromagnetic vibrator, Fig. 5 (not shown). The output signal from the synchronous detector (representing vapour flow detected by the ion gauge) is compared in a differential amplifier 45 with a desired flow signal from a reference source 46 and the error signal is used to control the electron gun to generate an even flow of vapour. An error-voltage-limiter 48, comprising diode clippers, is provided to avoid error-signal-peaks overloading the control circuitry. The filament current of the ion gauge may be automatically regulated in accordance with the deviation of the bias from a reference value in a closed loop circuit 51.. 55.

Abstract: 1453982 Battery cassette POLAROID CORP 10 Dec 1973 [15 Dec 1972] 57103/73 Heading H1B A cassette 23 for mounting in the handle 22 of a movie camera and retaining four elongate cells in side-by-side relationship comprises an elongate portion 28, Fig. 2, and a cap portion 30, Fig. 3, the resilience of the side walls of portion 28 permitting that portion to be latched by tabs 60 to apertures 62 in portion 30. End walls 32, 34 of the portions 28, 30 have apertures 36, 38, 40, 42 and 44, 46, 48, 50, respectively. Apertures 36, 42, 46, 48 receive the positive cell terminals, which terminals extend centrally from one end of the cells. The apertures 38, 40, 44, 50 are larger and receive contacts which extend from outside the cassette to engage the negative cell terminals formed at the other end of the cells by the cell casings. The apertures 36, 42, 46, 48 are at the centre of recesses formed in the inner surfaces of the walls 32, 34 and pairs of ridges 52, 54 at the aperture 36, extend from these recesses. Thus, should a cell be incorrectly inserted to give a reversed polarity, the ridges space the negative end of the cell away from the wall 32 or 34 and prevent engagement of the negative cell terminal with a contact 82 which enters an aperture such as 36 a predetermined distance until restrained by shoulders on the contact. Further, the negative contacts are wider and cannot enter a positive aperture such as 36 to engage a positive cell terminal. The cassette 23 is retained in a housing 25 on the handle 22, the housing comprising a main body part 24 and a detachable part 26, Fig. 4. A bayonet cross-pin 68 in a post 66 co-operates with a slot 64 in the cassette to ensure correct orientation of the cassette in the housing 25. The part 26 carries a rotatable bayonet socket number 104 having slots 106 for engaging the cross-pin 68, this engagement being made by rotating a toggle arm 108 pivoted thereto whereby the part 26 is secured to the part 24. The contacts 86, 88, 90, 92, Figs. 4, 6, are spring urged towards the positive and negative cell terminals to connect the cells in series.

The target 6 may initially be tritiated, but preferably is not so and comprises titanium on a copper backing. In the latter instance, tritiation occurs during an initial operating phase of the generator.

As shown, an electrode 6 of an arc furnace is raised or lowered by a motor 17 supplied from a main generator 24 driven by an A.C. motor 25. An exciter 26 supplies the main generator field and has two control field windings 34 and 35 which oppose each other. A self-exciting winding 36 is preferably provided and a differential field winding 37 is energized from the main generator 24. A current transformer 44 supplies the control winding 34 through a rectifier 43. The control winding 35 is supplied through a rectifier 53 connected across the arc. The regulator may be adjusted so that the two control field windings neutralize each other at the desired arc current and voltage by adjusting the resistors 47, 56. The self-exciting field winding 36' increases the rate of build up, where the field windings 34 and 35 are unbalanced, the differential field winding 37 preventing hunting. The relay 57 modifies the normal operation of the exciter field windings principally to neutralize the effect of residual magnetism in the exciter 26.
