Title: Apparatus for Interrupting an Electrical Supply Line
Inventor: PIPPONZI ADRIANO
IPC: H02H3/06
Filed: 1967-03-01
Abstract: 1,183,482. Protective arrangements. A. PIPPONZI. '1 March, 1967 [5 March, 1966], No. 9590/67. Heading H2K. [Also in Division H1] When a main automatic reclosing circuitbreaker opens, the resulting loss of voltage at each subsidiary circuit-breaker in the distribution system controlled by the main circuitbreaker causes the undervoltage coil d of each subsidiary circuit-breaker to release a lever p which is moved by a spring e to unlatch the main contacts c which open, auxiliary contacts z being closed. A projection j on a lever r rigidly connected to the lever p moves into a slot i in a disc H. When the main circuitbreaker recloses and restores the supply to a, the undervoltage coil d is energized and restores the levers p, r, the reclose mechanism v is energized, and through contacts z a relay o is energized to complete a circuit for a drive motor g for the disc H. The initial movement of the disc H causes contacts n to close to maintain the motor g energized as the contacts z are opened as the circuit-breaker recloses. Should the fault condition remain, and the main contact-breaker reopen, then the resulting loss of voltage causes the release of the levers p, r, as the disc H has been turned to such a position that the projection j on the lever r can move into a deeper slot l and open contacts u which interrupt the circuit of the coil d and relays o and w so that the circuit-breaker opens and remains open. If the fault had cleared, then disc H rotates until it reopens the contacts n to interrupt the supply to its drive motor g. In a modified arrangement the slots i and I are replaced with rollers which co-operate with a latch for the lever r, Figs. 5 and 6 (not shown).

Inventor: JUSTONI ROMEO
IPC: C07D209/16
Filed: 1955-04-01
Abstract: The invention comprises (1) the compound 5-benzyloxy-indole-3-b -propionazide, (2) the preparation therefrom of b -[3-(5-benzyloxyindolyl)]-ethylcarbami esters with alkanols of up to 5 carbon atoms and with benzyl alcohol, and (3) the following synthesis of 5-hydroxytryptamine using the above as intermediates: 5 - benzyloxy - 2 - carboxyindole - 3 - b  - propionic acid (see Specification 766,036) is decarboxylated by heating to 190-230 DEG C., the product esterified with an alkanol of up to 5 carbon atoms and the ester reacted with hydrazine hydrate to give 5-benzyloxy-indole-3-b -propionhydrazide; the latter is converted into the azide by treatment with sodium nitrite and acid in the presence of ether, an aliphatic alcohol of 4-5 carbon atoms, benzene or a methyl-substituted benzene as solvent; the azide is heated to 60-140 DEG  C. with the appropriate esterifying alcohol (if not already present as solvent) to form the b -[3-(5-benzyloxyindolyl)]-ethylcarbamic ester (via the isocyanate, not isolated); finally 5-hydroxytryptamine is obtained from the carbamic ester by catalytic hydrogenolysis and acid hydrolysis simultaneously or successively in either order. The hydrogenolysis is preferably carried out with a palladium catalyst in alcoholic solution, and if hydrolysis precedes this the 5-benzyloxytryptamine may be isolated as its benzoate or salicylate.  Examples show the preparation of the following :-(1) 5-benzyloxy-indole-3-b -propionic acid and its methyl ester, hydrazide and azide, methyl b -[3-(5-benzyloxyindolyl)]-ethylcarbamate, methyl b -[3-(5-hydroxyindolyl)]-ethylcarbamate, methyl b  - [3 - (5 - hydroxyindolyl)]-ethylcarbamate and 5-hydroxytryptamine (isolated as picrate); (2) as in (1) but proceeding via 5-benzyloxy-tryptamine salicylate or benzoate; (3) as in (1) but forming the ethyl esters instead of the methyl esters; (4) as in (1) but converting the azide to benzyl b -[3-(5-benzyloxyindolyl)] - ethylcarbamate and the latter directly to 5-hydroxytryptamine, isolated as picrate or as the double sulphate with creatinine. The isoamyl ester of b -[3-(5-benzyloxyindolyl)]-ethylcarbamic acid is also mentioned.

Title: Improvements in or relating to the production of high alphacellulose
IPC: D21C9/08
Filed: 1926-04-13
Abstract: 278,767. White, A. E., (Brown Co.). April 13, 1926. Pulp, preparation of. - Chemical pulp, such as sodium or calcium bisulphite pulp, is treated with an alkaline solution, such as caustic soda, sodium carbonate, sodium carbonate and caustic soda, or sodium sulphide of concentration and temperature such as to effect a purification but insufficient to effect mercerization. so as to produce a product rich in alphacellulose and suitable for the production of cellulose esters or ethers or of high grade paper. The pulp mav be treated with an oxidizing or bleaching liquor before the alkali treatment and is treated with the usual bleach liquor after the alkali treatment, followed by a "super-bleaching" with chlorine water. The pulp is fed from a tank 1 to a regulating tank 3 in which water is added, and passes thence to thickeners 4, the thickened pulp being discharged to a mixer 7 which receives alkali from a heater tank 8. The alkali is fed from a store tank 12 through a smaller store tank 14 to a " doser " 15 which regulates the supply to the heater tank 8. The pulp from the mixer 7 is sent to thickeners 10, and the thickened pulp is discharged to cooking tanks 11 and 38 in which the digestion is effected. Steam from a pipe 36 is supplied to the various tanks under the control of thermostats 34. 35, 46, and water is added when necessary to the tank 8 by means of a float 16 and diaphragm valve 33. The treated pulp overflows from the digesting tank 38 into a washer 45. The pulp may be freed from traces of alkali by adding a bisulphite or sulphurous acid, and is then treated with bleaching powder solution, with the addition of a little caustic soda if desired to retard the bleaching action and lessen the danger of weakening the fibre. The washed or unwashed bleached fibre may be " super-bleached " by chlorine water, and is finally treated with a little bisulphite liquor to remove remaining chlorine. Thepulp is then led to rifflers to remove heavy impurities and to a classifier to remove more or lessthe broken or shorter fibres, which are suitable. for the production of cellulose derivatives.

Abstract: 1507605 Recoil damped percussion tool ATLAS COPCO AB 12 March 1976 [18 March 1975] 09962/76 Heading B4C [Also in Division B3] A recoil damped percussion tool comprises a work tool 22, a machine housing coupled to the work tool and adapted to apply a feeding force to the work tool in a working direction, a hammer piston 17 which reciprocates in the machine housing to deliver impact energy to work tool 22, the work tool recoiling after an impact, and a recoil damping device comprising a retard chamber 70 in the machine housing containing pressurized hydraulic fluid, and a retard piston 68 which recoils with the work tool 22 and is acted upon by the hydraulic fluid in the retard chamber. Preferably, the retard piston has a piston surface 69 which forms the forward end of retard chamber 70 and the increase in pressure in chamber 70 when tool 22 recoils is damped by hydraulic fluid pressure reservoir 48 which is connected to retard chamber 70 by conduits 47 and 71. Driving means.-Hammer piston 17 is reciprocated to strike work tool 22 by hydraulic fluid supplied by inlet conduit 47 and controlled by distributing valve slide 46. In the position shown in Fig. 3 slide 46 allows fluid to enter conduit 55 and rear pressure chamber 39 to drive piston 17, whilst fluid driven from forward pressure chamber 43 flows through conduits 56 and 52 to a sump (not shown). Fluid from conduit 55 blows through passage 64 in slide 46 to act on annular piston surface 63 and maintains slide 46 in its left hand position. When the piston 17 has moved far enough to the left to allow high pressure fluid in conduit 55 to reach control line 62 via expanded rear chamber 39 and for control line 61 to be drained via middle chamber 15, valve slide 46 is pushed to the right. Chamber 43 is supplied with high pressure fluid and chamber 39 is drained to produce a return stroke of piston 17 until control line 61 is pressurized, control line 62 is drained and slide 46 shifted to the left to repeat the driving stroke. The length of the driving stroke is adjusted by blocking some of the branches of control line 61 by pin 67. Pressure reservoirs 48, 54 minimize pressure variations. Drill rotation. As shown work tool 22 is an adaptor intended to be connected to a drill string. A rotation chuck 23 is rotatably journalled in a gear housing 13 by roller bearings 24, 25. Chuck 23 is provided with a gear ring 26 which co-operates with a gear wheel 27 splined to a shaft 35 journalled in bushings 36, 37 and rotated by a hydraulic motor 38. A driver 28 transmits the rotation of chuck 23 to adaptor 22 which is axially movable relative to the driver. A rotational chuck bushing 33 has a collar 34 resting against a rear end of chuck 23 and retard piston 68. When the tool is pushed against, e.g. a rock, the fluid pressure on the retard piston exceeds the feeding force. Drill clearing.-Flushing fluid is applied to the axial hole of adaptor 22 and the drill string through flushing head 31. A stop ring 32 is mounted between the flushing head and driver 28.
