Title: Anthracene and anthraquinone dyestuffs
IPC: C09B7/12
Filed: 1932-01-29
Abstract: Thioindigoid dyes containing 2,1(S) anthracene or anthraquinone residues are prepared by treating an anthracene or anthraquinone-1-thioglycollic acid of the formul :-- <FORM:0398161/IV/1> wherein positions X or Y are occupied by halogen (particularly chlorine or bromine), nitro, sulpho, carboxy, hydroxy, amino, substituted hydroxy or amino and the anthracene or antrhaquinone nuclei may contain further substituents, with chlorsulphonic or a mixture of chlorsulphonic and sulphuric acids. When the substituent in X or Y is a substituted amino group the substituent in the amino group may form part of a ring structure attached to the anthracene or anthraquinone residue.  According to the substituents present the products are vat or acid dyes, or suitably treated they may be applied by the methods described in Specification 377,740.  In examples, (1) the lactam from 1-amino-2 : 5-dithioglycollic-anthraquinone (prepared according to Example 1 of Specification 398,162) is treated with chlorsulphonic acid at 20-25 DEG , to give a brown vat dye for cotton; the lactam ring may be hydrolysed by alkali and the product then applied to wool in the way described in Specification 377,740; if the above lactam employed as starting material is reduced by means of zinc dust and ammonia, and then the resulting anthracene compound treated as in (1) a brown vat dye is obtained: (2) the lactam from 1-amino-2,8-dithioglycollic-anthraquinone (prepared according to Specification 398,162) is treated with chlorsulphonic acid as in (1) to give a brown vat-dye: (3) similar treatment of the following derivatives of anthraquinone-1-thioglycollic acid is described or referred to:--5 amino-, 5-sulpho (both from the corresponding 1-mercapto derivatives and chloracetic acid), 5-chloro (from 5-aminoanthraquinone-1-thioglycollic acid by a Sandmeyer reaction), 5-o<1>-carboxyanilido (from the foregoing 5-chloro derivative and anthranilic acid), 5-hydroxy and 5-methoxy.  It is stated that reaction proceeds smoothly, whereas treatment of those thioglycollic acids containing no substituent in positions X or Y leads to little, if any, condensation.  The anthraquinone derivatives used as starting materials are prepared by the action of chloracetic acid on the corresponding mercaptans which are derived from substituted aminoanthraquinones or according to the processes of Specifications 10387/08, [Class 2, Acids and salts, Organic &c.], and 398,162.

Title: Improvements in or relating to electronic means for counting electrical impulses
IPC: H03K29/00
Filed: 1954-01-30
Abstract: 806,002. Electronic counting-apparatus. ERICSSON TELEPHONES Ltd., and ACTON, J. R. April 4, 1955 [Jan. 30, 1954], No. 2855/54. Class 106 (1). [Also in Groups XL (a) and XL (c)] In means for counting electrical impulses including two or more gaseous electric discharge devices each having first and second anodes, the production of a conductive discharge at the first anode in one device renders a second device impulse-responsive, and the application of an impulse to all the devices in common causes a conductive discharge to be produced at the first anode in the second device and thereby increases the value of a positive potential at the second anode of the first device and produces a conductive discharge thereat, whereon both discharges in the first device are automatically extinguished. The scale-of-five ring counter shown comprises 5 gas-filled tubes ET1-ET5 (see Group XL (a)) each comprising major and minor anodes a1, a2, a cathode k, trigger electrode t and " luminant " electrode l. The count is registered by a discharge between the major anode and cathode of one of the tubes, the major anode supply potential PA being greater than the minor anode supply potential PB, this discharge being stepped to the next tube in response to a positive-going pulse from IP applied to all the electrodes t through capacitors C21-C25. Initially a discharge is produced in ET1; the consequential positive cathode potential biases the electrode t of tube ET2 through resistor R21 so that this tube fires in response to the next pulse. The rise in cathode potential is applied through capacitor C11 to anode a2 of tube ET1 and produces a dicharge at this anode thus raising the cathode potential of ET1 sufficiently to extinguish the discharge to the major anode a1; the time constant of the minor anode circuit is short compared with that of the cathode circuit, so that the potential difference between a1 and k soon falls below the maintaining value and the discharge to this anode is also extinguished. The next pulse similarly causes ET3 to fire, the potential rise feedback through C12 extinguishing ET2, and so on. Every time the discharge reaches ET1, an output pulse is obtained on lead OP. Rectifiers ME1-ME5 prevent electrodes t from going negative relative to the cathodes.

Title: Improvements in or relating to electron discharge devices
IPC: H01J25/24
Filed: 1947-01-30
Abstract: 632,948. Velocity-modulated tubes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 30, 1947, No. 2890. Convention date, Sept. 21, 1943. [Class 39 (i)] In a reflex velocity-modulation tube with two resonator grids 14, 15, Fig. 1, defining a gap, the grid 14 being mechanically movable by flexing wall 19, heat expansion or contraction of collar 17 due to changes in temperature of the surrounding atmosphere is compensated by an equal thermal expansion or contraction of three struts 24 external to the evacuated envelope of the device, so that the gap width and hence the operating frequency are maintained substantially constant. The collar 17 is of copper, and each strut 24 comprises a prop 27, of cupalloy, brass or of the alloy known under the Registered Trade Mark "Duralumin," having a coefficient of linear expansion greater than that of copper, and a deeply socketed spacer 26 of an iron-nickel-cobalt alloy with a coefficient of linear expansion less than that of the prop. Pins 28 of stainless steel fit into both ends of the props 27. Two of the struts 24 seat in sockets in the plate 22 and the other one in a tuning lever 25 actuated by a micrometer screw (not shown). A change in tuning due to moving lever 25 does not affect the temperature cornpensation. The members 26 are threaded and pass through threaded apertures in the plate 21, so that their position may be adjusted during manufacture to tune the resonator to approximately the correct frequency. The members 26 are then kept in this position permanently by lock-nuts 29. Three springs 23 tend to urge the plates 21, 22 together. A focusing grid 16 is provided for the electron beam.

Filed: 1930-01-30
Abstract: 348,066. Motor power plant. JOHNSON, E. M., 33, Poplar Grove, Brooklands, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. Jan. 30, 1930, No. 3218. [Class 110 (iii).] In a power system wherein power is supplied to a main shaft by a main prime mover and an auxiliary prime mover not mounted on the same shaft as the main prime mover, the devices for controlling the respective outputs are so arranged that when reducing the output of the main prime mover, beyond a predetermined ratio to the output of the auxiliary prime mover, operative connection is established between the controlling devices and the output of the auxiliary prime mover is reduced. In the Figure lever 8 controls the main prime mover and rheostat arm 1 controls the velocity ratio of a coupling comprising a generator driven by the auxiliary prime mover and a motor on the main shaft. A sector 5 pivoted concentrically to the levers is notched and contacts with a spring detent 6. The lever 1 may be moved relatively to the sector but when the lever 8 is moved to reduce the output of the main prime mover, a stop 9 contacts with and moves the sector and lever 1 to reduce the output of the auxiliary prime mover. The arm 1 may be moved beyond the range of the studs, cutting off power to the motor, and when the main prime mover is completely shut down a latch 10 engages a pin 11 and to readjust the rheostat arm it must be moved to its extreme position where the lug 12 releases the detent. In a modified arrangement two rheostats are employed, one of which is hand adjusted but controlled by the position of the arm on the other rheostat. An arrangement is also described whereby the motor current is cut off if the main prime mover is reversed. The above controls may be applied to a regulator on the auxiliary prime mover.
