Title: Manufacture of azo-dyestuffs
IPC: C09B41/00
Filed: 1935-12-18
Abstract: Azo dyes are made in substance or on the fibre by treating with an oxidizing agent a mixture of an azo-coupling component and a salt of an aryl anti-diazo sulphonic acid or an aryl hydrazine sulphonic acid, followed if necessary by a treatment with an alkaline substance.  When the dyes are formed on the fibre the original amine and the coupling component should be free from solubilizing groups such as COOH or SO3H.  They may be produced on animal and vegetable fibres and on regenerated celluloses and cellulose ethers or esters. According to the examples: (1) a cotton fabric is printed with a mixture of sodium 2 - methyl - 5 - chlorobenzene diazosulphonate, the o-toluidide of 2 : 3-oxynaphthoic acid, alcohol, caustic soda, glycerine, starch tragacanth and water, dried, treated with steam and chlorine, washed and treated in a boiling bath containing soap and sodium carbonate (red); a table is given of other diazosulphonates and coupling components including arylides of 2 : 3-oxynaphthoic acid, 2 : 3-oxyanthracenecarboxylic acid, 2 : 3-oxycarbazolecarboxylic acid, 3<11> - oxy - 7<1> : 8<1> - benzocarbazole - - 2<11> carboxylic acid and acetoacetic acid and b -naphthol; (2) a cotton fabric is printed with a mixture of sodium-2-nitrobenzene diazosulphonate, the o-toluidide of 2 : 3-oxynaphthoic acid, caustic soda solution and starch tragacanth, dried and passed through an aqueous solution of chlorine (yellowish scarlet); other components specified are 2-nitro-4-methylbenzene and 2 : 5-dichlorbenzene diazosulphonates and the o-anisidide of 2 : 3-oxynaphthoic acid (in the latter case the dyeing is developed by means of a boiling salt solution through which chlorine is passed; (3) 5-chloro-2-methylbenzene hydrazine sulphonic acid is used as in (1) instead of the diazosulphonate; (4) printing is conducted as in (1) with sodium 2-methoxy-4-chlorobenzene diazosulphonate and the o-anisidide of 2 : 3-oxynaphthoic acid and the dyeing developed by passing the moist material first through an atmosphere of chlorine and then through an atmosphere of ammonia or through a soda solution; (5) similar to (1) using tragacanth mucillage instead of starch tragacanth; (6) a current of chlorine is passed through a cold solution of sodium 2-methyl-5-chlorobenzene diazosulphonate, the o-toluidide of 2 : 3-oxynaphthoic acid, alcohol and aqueous caustic soda to precipitate the dyestuff; (7) a solution of sodium 2-naphthol-6-sulphonate, sodium 2 - methyl - 5 - chlorobenzene diazosulphonate, sodium bicarbonate and salt in water is treated with a current of chlorine and the orange wool dye is salted out. Other oxidizing agents specified are bromine, hypochlorites and bromates in presence of an acid, nitrous acid or lead peroxide in an acid medium.

Patent GB-354956-A (GB)
Abstract: 354,956. Multiplying and dividing apparatus. MONROE CALCULATING MACHINE CO., 555, Mitchell Street, Orange, New Jersey, U.S.A. July 11, 1930, No. 21072. Convention date, Aug. 12, 1929. [Class 106 (i).] In a machine for automatically dividing by subtracting and adding alternately in successive denominations, the reversal of drive and shifting of the carriage are effected at each tripping action of the highest numeral wheel. As applied to the Monroe machine described in Specifications 216,174 and 334,045, [both in Class 106 (i), Calculating &c.], the division setting-lever 201 when pushed rearwards (1) rocks a latch lever 303 to raise and hold the lock-lever 200, (2) by a pawl 319 rocks the clutch control lever 111 to set the machine in subtractive operation, and (3) through a pin 211 advances the sliding-tooth 209 into operative relation with the reversing tooth 220. At each trip of the lever 31 and consequent operation of the arm 24, a lever 52 is rocked by a link 47 to operate the carriage-shifting shaft 46. When the carriage reaches its extreme left-hand position it depresses a lever 223 and thus a slide 311 to bring the latter into the path of a lug 314 on the crank arm of shaft 4. The slide is thereupon operated to restore the division lever to normal position. When therefore the machine next performs an adding rotation in this extreme position, no further reversals occur as a pin 219 on the division lever causes the latch 213 to release the sliding-tooth 209. The lock-lever 200 is freed by the latch 303 at the end of the operation owing to the camming engagement with pin 310 on tooth 209 of the nose of an arm 307 pivoted to the latch and thrust upwards by the pin 145.

Title: Automatic change speed gear arrangement for motor vehicles
IPC: F16H61/02
Filed: 1967-08-02
Abstract: 1,139,269. Change-speed control. DR. ING. H.C.F. PORSCHE, K.G. 2 Aug., 1967 [2 Aug., 1966], No. 35576/67. Heading F2D. A change-speed control providing for both fully automatic and manual shifts in a conventional three speed and reverse gear comprises an electric control circuit supplied with output speed and accelerator position responsive signals which controls an electric motor 24 which effects the gear shifts. For manual shifts a gear lever successively closes switches K 2 -K 4  introducing parallel connected resistors 25-27 into the circuit of the selector motor 24 to give first, second and third ratios. A gear lever controlled switch K 5  is closed only when the lever is put into a neutral position, and introduces a resistor 28 into the circuit. A feedback circuit provides a feedback voltage correlated to movement of the motor 24 for neutralizing the control voltage produced by the resistors 25-- 28 after the motor has moved the required amount. For automatic shifts the gear lever is moved to an automatic position in which the neutral switch K 5  is open and switches K 1  and K 2  are closed, so that first gear is established and transistor, trigger circuits A, B are connected in parallel into the circuit and serve respectively to by-pass the switches K 3 , K 4 . At a predetermined value of the output speed and accelerator position responsive signal the trigger circuit A is actuated and resistor 26 is brought into the circuit to give second gear. When the control signal increases to a second value circuit B is actuated to bring resistor 27 into the circuit for third gear.

Title: Improvements relating to the filling of cracks or crevices in foundations
IPC: E02D3/12
Filed: 1931-12-23
Abstract: 391,534. Filling cracks in foundations. DEUTSCHE WERKE KIEL AKT.-GES., 114, Werftstrasse, and KLIE, W., 54, Adolfstrasse, both in Kiel, Germany. Dec. 23, 1931. No. 35599.- [Class 20 (ii).] Filling material is injected into crevices and cracks by means of a tube which is sealed off or tamped into the hole leading to the parts to be filled by liquid sealing material before injecting. The filling tube a is provided with a flange i, Fig. 1, and washer k and is surrounded by another tube b which can be secured to it by a screw d. The outer tube is sealed into the borehole by material SZ, and time is allowed for setting. Material is then pumped through the tube a by means of a supply tube hand valve g. If further material at a lower level is to be injected filling material is supplied through a branch e to the space between the tubes and the inner tube is forced downward carrying the sealing material with it which is then allowed to set before injection again begins. After injection the ends of the tubes are cut away and the remainder serves as a ground anchor for the concrete. In some cases the borehole is rough and uneven and a washer does not fit it ; in such a case injecting material may pass behind the flange of the inner tube as it is depressed and this must be allowed to set before fresh injection. To expedite this a current of electricity may be passed from the injecting tube to the outer tube to heat the intervening cement, the tubes being suitably insulated from the ground and from each other. The outer tube may not be used, the inner tube a<1> in this case being directly sealed above its flange and having a screwed connection with the flanged head i, Fig. 2 ; after injection the injecting tube is unscrewed and used with a further head i, the first head i being left in the borehole. In other cases a flexible bag p may be passed down the filling tube and expanded to form a stop for the sealing material SZ, Fig. 3, and to block off temporarily the crevices and cracks and prevent any one borehole being filled from an adjacent one. After the sealing material has set the bag is deflated and removed and to allow of this being easily effected the end of the tube a is expanded outwardly to a conical formation.

Title: Improvements in or relating to electric selective arrangements for operating alarm devices
IPC: H04L15/26
Filed: 1928-12-03
Abstract: 301,753. Soc. Francaise Radio-Electrique. Dec. 2, 1927, [Convention date]. Selectors responsive only to particular code signals. Apparatus or responding to a distress signal consisting, for example, of foursecond dashes separated by onesecond spaces, comprises separate arrangements for testing the lengths of the dashes and spaces, and a counting-relay chain for summing the effects of the dashes, so that after three have been received, an alarm is operated. Dashes of duration between three and five seconds and spaces of less than two seconds are regarded as correct. In one system, Fig. 1, the tests as to the lengths of dashes and spaces are effected by pendulums controlling counting relays. At the first signal, relay MN releases pendulum BT and operates contacts 5 connecting the +pole to points +a. At the end of one second the closing of contacts 6 sends an impulse to operate relay Tl which at the end of the impulse locks in series with relay AT1. Succeeding impulses pass in a similar way to relays T2, T3, T4. Relay T3 energizes relay E1 which at the end of the dash locks in series with relay AE1 owing to the release of relays T1 - - AT4 when relay MN releases. The first dash is thus stored on relays E1, AE1 provided that it lasted more than three seconds. Two further dashes, if correct, similarly operate relays E2 - - AE3 and operate. the alarm SIV. If a dash lasts longer than five seconds, the fifth impulse from contacts 6 passes over contacts 17 to operate relay ZO which releases the storage relays. If a dash lasts less than three seconds relay ZO is operated upon the release of relay MN over contacts of differential relay TC which is operated after one second by relay T1 but is neutralized after three seconds by the operation of relay T3. After the first dash has been stored, relay SL operates during spaces to release pendulum BE which after one second operates relays E, AE and after two seconds, if a space lasts so long, operates release relay ZO. In a modification, Fig. 2, the relays T1 - - AT4, E, AE are replaced by drums RT, RE which are coupled by the dash and space magnets MN', SL<1>, respectively, to a continuously-rotating shaft A. Contacts 18<1>, 14<1>, 17<1> closed after one, three and five seconds, respectively, correspond to contacts 18, 14, 17, Fig. 1, and contacts 25<1> similarly correspond to contacts 25.
