Abstract: 301,197. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 21, 1927. Addition to 289,980. Dibenzanthrone and isodibenzanthrone dyes are obtained by alkali fusion of 5-, 6-, 7-, and 8- aminobenzanthrones. In examples, dyes giving a bordeaux-red solution in sulphuric acid are obtained by alkali fusion, with caustic potash at 230‹ C., or 5-, 6-, and 7-aminobenzanthrones, and dye blue, green-grey, and violet respectively. A mixture of the two last products in the proportions of 4 to 1 respectively dyes cotton a deep black. By alkali fusion with 55 per cent alcoholic potash at 150‹ C., 5-aminobenzanthrone gives the same product as with caustic potash alone at 230‹ C., but 6-aminobenzanthrone, with alcoholic potash at 170‹ C., gives a dye soluble in sulphuric acid to a grey-green solution, and dyeing grey-violet, and 8-aminobenzanthrone, with alcoholic potash at 150‹ C., gives a dye soluble in sulphuric acid to a green solution, and dyeing greyish-blue. Specifications 12518/06 and 254,742 are referred to. Aminobenzanthrones. 5-, 6-, 7-, and 8-Aminobenzanthrones are obtained from the corresponding halogen derivatives by the action of ammonia at elevated temperatures.

Title: Improvements in and relating to dry adhesives composed of rubber or rubber latex
IPC: C09J107/02
Filed: 1934-11-01
Abstract: The efficiency of rubber based dry adhesives of the kind consisting of rubber latex or rubber dissolved in benzol or like solvent is improved by treating the foundation material or the rubber compound or both with a suitable wetting out agent, such as the sodium salt of a higher sulphonated fatty alcohol or sulphonated aromatic hydrocarbon, or sulphonated vegetable, fish, or animal oil or the like.  The adhesive quality of the compound may also be improved by incorporating therewith colloidal substances such as gums, starches, dextrins, rosins, soaps, gelatine, casein, or other animal or vegetable proteins either alone or emulsified with rosin, soap, or an oil of either animal, vegetable, or mineral origin.  Stability and adhesiveness are also enhanced by adding a vulcanizing agent and an accelerator whereby vulcanization at a relatively low temperature is effected A stabilizer and an anti-oxidant may also be added.  The addition of the wetting-out agent ensures especially good cohesion between the rubber compound and foundation material when the latter is composed of coated paper or paper sized with a gelatine, casein or protein of animal or vegetable origin, or starch, silicates, rubber, nitrocellulose, cellulose acetate, gums, or their derivatives.

Title: Improvements in or relating to static inverters
Inventor: START JAMES DENNIS MICHAEL
IPC: H02M7/525
Filed: 1963-08-09
Abstract: 1,026,983. Protecting transistor circuits. E. K. COLE Ltd. July 28, 1964 [Aug. 9, 1963], No. 31450/63. Heading H3T. [Also in Divisions G3 and H2] In a static inverter the semi-conductor switching devices are protected from current overloads by a sensing circuit which reduces the conduction angle of the devices and at the same time utilizes a predominant harmonic of the inverter fundamental frequency present in the output current waveform to operate a cut-out in the load circuit. Under normal load conditions voltage feedback from across the load R 2  to a regulating stage 2 maintains a constant output voltage by varying the conduction angle of the semi-conductor devices in the inverter output stage 3, and a filter circuit L 1 , C 1  connected across an output transformer T 1  and resonant at the fundamental frequency results in the current through the load comprising mainly the fundamental frequency. An output current control circuit comprising C 2 , D 1 , D 2 , R 1  and a current transformer T 2  generates a control potential which is applied to the regulating stage 2 and which is arranged to override the output voltage feedback for output currents above a predetermined threshold value. Under short-circuit load conditions an inductance L 2  (whose impedance at the fundamental frequency is low compared with R 2 ) is effectively in shunt with L 1  and C 1  and its value is chosen so that the combination L 1 , L 2 , C 1  resonates at a predominant harmonic of the fundamental frequency. The values of C 2 , R 1  and the turns ratio of T 2  may be chosen to favour the production of this harmonic under short-circuit load conditions. With a large harmonic content in the output waveform due to resonance of the combination L 1 , L 2 , C 1  the RMS current through the fuse 8 is higher than for a predominantly fundamental output and is sufficient to operate the fuse 8. In various modifications the inverter may be provided with more than one output, T 2  may be connected on the load side of T 1 , L 1  may form part of T 1 , L 1 , C 1  may be connected across the inverter side of T 1 , or T 1  may be omitted altogether.

Title: Improvements in or connected with miniature billiard tables
IPC: A63D15/00
Filed: 1921-11-29
Abstract: 189,347. Gardner, L. F., (Rezßc, G.). Nov. 29, 1921. Table games.- Relates to a miniature billiard table of the type in which means are provided for raising the balls on to the table, and, in which a guide capable of horizontal movement is situated at the centre of one end. The invention consists in forming the guide with a fork for holding and adjusting the ball, and positioning the ball-delivery opening so that it is in the fork when the fork is in the middle position. The table 1, Figs. 1 and 2, is surrounded by cushions 14 and closed in bv a glass plate 2. At the centre of one end cf the table is a rotatable roller 3 carrying a forked guide 6 and a horizontal spring cue 5 operable from outside the casing. The table is pivoted at the cue end and rests at the other end on a trough-shaped guide 9, which is pivoted to a plate 9 and supported by an arm 10 on a shaft 11 rotatable from outside the casing by a lever 13. The table may be levelled by adjusting the screwed feet 40. Balls are raised on to the table one at a time through a vertical tube 18 by a piston 17 operated by a pivoted lever 19. A guard 7 is provided above the tube 18 to prevent the balls hitting the glass 2. When all the balls have been played, the lever 13 is depressed to allow the balls to run off the table into the guide 8 and return to the opening 16 in the tube 18. In its normal position, the piston obstructs the opening 16, so that in order to raise a ball, the piston is first lowered and then raised. In lowering the piston, the end of the lever 19 depresses a lever 20 against the action of a spring 23, and a spring pawl 26 on the lever 20 rotates a ratchet-toothed wheel 27. When a certain number of balls has been raised, a pin 34 on the wheel 27 raises a catch 32, Fig. 4, which allows a bolt 30 to move under the action of a spring 31 and enter a slot 29 in the wheel 27, thus locking the wheel and preventing the lowering of the piston 17. The mechanism may be freed by inserting a coin 36<1> in a slot 42 and rotating a disc 35. The coin 36<1> enters a recess 36 in the disc 35 and as the disc is rotated presses back a lever 37 and with it the bolt 30, until the catch 32 drops in front of a shoulder 30<1> and secures the bolt in the open position.
