Title: 17-formyl audrostadiene derivatives and the preparation thereof
IPC: C07J75/00
Filed: 1954-05-17
Abstract: The invention comprises 17-formyl-cyclopent-16 - eno - 10 : 13 - dimethyl - D 4 - dodecahydrophenanthrene - 3 : 11 - diones of the general formula <FORM:0754373/IV(a)/1> and a process for their preparation by treating a 16 : 17 - dihydroxy - cyclohexano - 10 : 13-dimethyl - D 4 - dodecahydrophenanthrene-3 : 11-dione with aqueous periodic acid and cyclodehydrating the resulting dialdehyde with an ammonium or amine salt of a mono-carboxylic acid in the presence of an inert organic solvent.  The 16 : 17-dihydroxy compound may be prepared by hydrolysis of a corresponding di-(monocarboxylic acid) ester or unsubstituted cyclic acetal, particularly the diacetate or the acetonide, which in turn is prepared from a diester or cyclic acetal of 16 : 17-dihydroxycyclohexano - 10 : 13 - dimethyl - D 4,9(11)-decahydrophenanthrene-3-one by treatment with a hypohalous acid, then oxidation with a chromium oxide-tertiary amine complex of the 9-halo-11-hydroxy derivative produced to the corresponding 9-halo-11-keto compound, followed by reductive dehalogenation with a metal in an acid medium.  The 16 : 17-groups may be derived from the following acids: acetic, propionic, butyric, isobutyric, valeric, caproic, pelargonic, myristic, stearic, phenylacetic, hydrocinnamic, g -phenylbutyric, benzoic or toluic; and the cyclic acetals from symmetrical ketones, e.g. acetone, diethyl ketone, cyclohexanone and p-methyl cyclohexanone.  In an example: dl-3-keto-16a  : 17a -dihydroxy - D 4,9(11) - D - homoandrostadiene diacetate in aqueous acetone is treated with N-bromosuccinimide to give dl-3-keto-9-bromo-11 : 16a  : 17a  - trihydroxy - D 4 - D - homoandrostene-16 : 17-diacetate.  The 9-chloro-and 9-iodo-analogues are prepared from it by conversion to the 9 : 11-epoxide with potassium acetate in boiling ethanol, followed by treatment with hydrogen halide in chloroform.  Subsequent oxidation of the 9-bromo-D-homoandrostene diacetate with chromium trioxide and pyridine yields dl-3 : 11-diketo-9-bromo-16a  : 17a  - dihydroxy - D 4 - D - homoandrostene diacetate, which on treatment with zinc dust and glacial acetic acid furnishes dl-3 : 11-diketo - 16a  : 17a  - dihydroxy - D 4 - D - homoandrostene diacetate.  The ester is saponified to the 16 : 17-diol, which is cleaved with periodic acid in dioxan and the resulting dialdehyde cyclized in acetic acid-piperidine to dl - 3 : 11 - diketo - 17 - formyl - D 4:16-androstadiene.  Other examples illustrate the above process using the corresponding 16b  : 17b -, and 16a  : 17b -isomers, various individual optical isomers, and also using the dipropionates and acetonides. Specification 749,214 is referred to.

Title: Cable layers
IPC: H02G1/06
Filed: 1943-09-03
Abstract: 570,859. Cable laying. WILSON, W. Sept. 3, 1943, No. 14454. Convention date, June 28. [Class 78 (v)] Apparatus for laying, and taking up, cable, wire &c. is mounted on a vehicle so that as the vehicle progresses the cable &c. is power expelled, thus enabling it to be flung rapidly, and, if desired, laterally. The cable drum 18 is mounted removably on a shaft 23 journalled at 22 and carrying at its further end a brake drum 24 having a pulley groove on its periphery. An I.C. motor 50 mounted above and forward of the drum 18 adjustably on a platform 43 drives the pulley 29 through a belt from a pulley 83 on the motor shaft 56, when cable is to be wound on the drum 18, a starting pulley 84 being also provided. On the opposite side of the shaft 56 is a grooved rubber-tyred wheel 57 which co-operates with a spring-pressed idler wheel 60 to grip the cable 68 and eject it through a guide 70. The wheel 60 is carried in a housing 61 which can be adjusted vertically on a frame 53, and has pivoted to it at 75 the spring-biased support 72 for the guide 70, which is in the form of a ring adjustably mounted on the support 72, the angle of adjustment determining the angle at which the cable is cast off. The motor 50 is movable to and fro along the platform 43 by a spring-retracted brake handle 36 pivoted at 37 and connected to the platform by a telescopically adjustable rod 51. The position of the motor and its Wheel 57 determines whether the cable is being gripped between the wheels 57 and 60, and being cast off, or not, and the to and fro motion effects tilting of the support 72 by an incline acting on a roller 77. The support 72 has a projecting pin 82 which holds the cable 68 off the motor wheel 57 when this is withdrawn from co-operation with the wheel 60. The whole apparatus can be turned about a vertical axis through 360‹ on a base 11 adjustably mounted on a vehicle by extensible grippers 14, 15. Specifications 469,620, 482,603, 487,513 and 509,053 are referred to.

Abstract: 1,105,123. Reactors. SNAM S.p.A. 6 April, 1965 [8 April, 1964], No. 14640/65. Heading G6C. A gas-cooled nuclear reactor comprises a prestressed concrete pressure vessel inside which heat exchangers 1 in sections formed as prefabricated units are arranged in an annulus such that they can be introduced into and removed from the vessel through a single central opening 4 in the vessel wall. The prefabricated units each comprise a manifold 10 housed in a removable duct section 8 and a coil bank 11. The removable duct sections 8 are integral with removable structures 7 disposed within a fixed structure 6, fixed duct sections between which the removable sections are mounted being integral with this fixed structure 6. The individual coil banks 11 are introduced through the central opening 4 in the roof of the pressure vessel which can be sealed by means of a gastight shielding plug 5 and the weldings necessary are limited to those between the manifolds 10 and the corresponding pipes which pass out through the vessel wall. In order to replace coil bank 11, it is only necessary to out the relevant manifold 10, disconnect the relevant removable duct section 8 from the adjoining sections which are integral with the fixed structure 6, and disconnect the structure 7 from the fixed structure 6. The coil banks 11 are moved to and from the centre space 3 of the annulus beneath the opening 4 by means of a travelling dolly. A passageway 12 through the vessel wall permits access to the duct and may be used for the plugging of one or more coils by an operator who enters the passageway only after the reactor has been shut down and cooled off. A blower 13 for the coolant gas flow is mounted on the vessel wall so that it can circulate the gas coming from more than one heat exchanger section without impeding the individual removal of any section for maintenance.

Title: Process for improving dyeings after-treated with copper compounds
IPC: D06P1/56
Filed: 1945-06-13
Abstract: Dyeings which have been produced with dyestuffs whose complex copper compounds are sparingly soluble or insoluble in dilute alkaline baths, and which have been after-treated with copper compounds, are improved by further treatment with a water-soluble reaction product of formaldehyde with a compound of the urea group which consists of elements of an atomic weight not greater than 16 and contains less oxygen relatively to carbon than is present in urea, e.g., cyanamide, dicyandiamide, dicyandiamidine, melamine, guanidine, acetoguanidine, or biguanide.  In an example, cotton yarn or regenerated cellulose staple fibres are dyed from a bath containing the dyestuff 1 - amino - 2 - methoxybenzene - 4 - sulphonic acid - W2 - (41 - amino) - benzoylamino - 5 - oxynaphthalene - 7 - sulphonic acid --> 8 - oxyquinoline, sodium carbonate, sodium sulphate and the sodium salt of N-methyl-m -heptadecyl-benzimidazole sulphonic acid, coppered by adding a solution of copper sulphate and tartaric acid neutralized with caustic soda, rinsed, and further treated in a solution of the water-soluble condensation product of dicyandiamidine and formaldehyde.  In place of the above dyestuff there may be used the dyestuff 4,41 - diamino - 3,31 - dioxydiphenyl \sQ 1 - (41 - oxy - 31 - carboxy) - phenyl - 3 - methyl-5 - pyrazolone, or 4,41 - diamino - 3,31 - dioxydiphenyl \sQ 1 - (31 - sulphonamido) - phenyl - 3 - methyl - 5 - pyrazolone, or 4-amino-41-oxy - 2 - methyl - 5 - methoxy -1,11-azobenzene - 31-, carboxylic acid (2 mols.) --> 5,51 - dioxy - 2-21 - dinaphthylamine - 7,71 - disulphonic acid.  In a second example, mixed yarn of wool and regenerated cellulose staple fibres is dyed from a bath containing 4,41-diamino-3,31-dioxyphenyl \sQ 1 - (41 - oxy - 31 - carboxy) - phenyl-3 - methyl - 5 - pyrazolone, 2 - amino - 4 - chloro-1,11 - diphenyl ether --> 1 - p - toluene sulphonylamino - 8 - oxynaphthalene - 3,6 - disulphonic acid, the sodium salt of N-methyl-m -heptadecyl-benzimidazole sulphonic acid and sodium sulphate, the dyeing developed by adding a neutralized solution of copper sulphate and tartaric acid, and then treated with a water-soluble condensation product from dicyandiamidine and formaldehyde.  Specification 455,274 is referred to.  The Specification as open to inspection under Sect. 91 includes also an example in which Cotton Blue N or Diamine Brown M is the dyestuff used.

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M1/10
Filed: 1942-10-27
Abstract: 561,677. Spray carburetters. BENDIX AVIATION CORPORATION. Oct. 27, 1942, No..15089. Convention date, July 20, 1941. [Class 7 (iii)] In a carburetter having an air inlet controlled by a suction responsive choke valve and temperature. responsive means for closing the valve when cold, yielding means are provided for urging the choke valve from the closed to a predetermined partly open position. A thermosensitive coil and a suction actuated piston act in known manner on the shaft 20 of an unbalanced choke valve 18, the one to close and the other to open the valve. When the valve is fully closed, an arm 54 on the shaft 20 draws upward a rod 52 pivoted thereto and compresses slightly a coil spring 68 surrounding the rod and abutting against a stop 74 comprising a bent wire secured at its ends by bolts 80 to the cover 76 of the float chamber. At starting, the spring 68 reduces the closing force of the thermo-sensitive coil until the coil, in opening the choke, lowers the rod 52 sufficiently to allow the spring 68 to expand to its normal length; thereafter, the full force of the coil operates, the arrangement being adapted to meet the requirements for starting an engine that has-been stopped but has-not had time to cool off completely. At its lower end, the rod 52 engages in a slot 50 in an arm 46 forming part of a fast idling mechanism 46; 56 which provides a variable stop for the throttle valve 23. In a modification, the spring 68 and stop 74 are replaced by a bimetallic strip having one end secured by one of the bolts 80 and the other end slotted to receive the rod 52. The strip is disposed nearer the engine than the thermo-sensitive coil and opposes the coil with a force dependent on the temperature of the engine.

Title: Improvements in or relating to hoisting devices
IPC: B66D1/74
Filed: 1959-05-04
Abstract: 901,995. Hoists. ARNOLD, C. H. May 4, 1959, No. 15261/59. Class 78 (5). A winch, intended for sustaining a bosun's chair on a fixed rope 35 and for raising and lowering it thereon, is provided with several safety devices. The chair is secured to the frame of the winch. Drum construction (Fig. 8).-The drum 3 is formed with grooves 40-44 and is associated with fixed guide elements 50-54 so as to allow the rope 35 to be wound in the manner shown to avoid slippage. Hand drive (Figs. 1, 5).-Handle 16 drives drum 3 via shaft 10, gear 9 and gear 10. The connection between handle 16 and shaft 10 includes screw 14, slidable disc 120 and flange 19 fixed to shaft 10. Additionally, ratchet 25 on disc 120 co-operates with pawl 127. Also disc 120 is provided with flange 121 for additional support. Pawl 127 is weighted at 135 to swing tip 126 towards ratchet 25, but also has a biasing spring around its shaft in the opposite direction to bring 136 into a non-locking engagement with the said ratchet 25. The effect is such that, when the winch descends at a slow speed, tip 136 is engaged by the ratchet to cause the pawl to swing back-and-forth. If, however, the handle should be inadvertently released so that the speed is increased, then the ratchet knocks the pawl at 136 to bring tip 126 into engagement with said ratchet and thus to check and hold the winch. The end of the biasing spring may be positioned in any one of the holes 133 formed in the pawl to predetermine the maximum speed thus permitted. Grip of rope on drum (Fig. 1).-This is increased by rollers 95-97 which are pressed by respective springs upon the rope 35 wound upon the drum. Safety lever 76 (Fig. 4).-This is pivoted at 71 and biased by a spring to engage the rope 35 at 79 (not shown). Additionally, shaft 71 carries spring 91 which co-operates with dog 88 which dog engages with gear 8. When the winch is stationary, lever 76 engages rope 35 and dog 88 engages gear 8. To lower, the operator disengages lever 76, which action causes spring 91 to disengage dog 88. Motor drive (Fig. 13).-The handle 16 may be removed and replaced by air motor 140, the motor-and-gear unit being attached to the winch frame by bolts 23, 24, 25. Specification 901,996 is referred to.

Abstract: 349,291. Turning-gear. MacMILLAN, C. H., 101, Strathcona Drive, Anniesland, Glasgow. May 19, 1930, No. 15273. [Class 7 (v). ] An engine starter comprises a motor-driven shaft 1 formed with a quick thread 2 engaged by a nut 4, a starter pinion 5 sleeved on the nut and having a frictional clutch connection with the nut, and a spring 8 tending to maintain the friction clutch in engagement and to resist endwise movement of the pinion on the nut. As shown, the friction clutch is formed by conical surfaces 6, 7 on the nut and the pinion, and the spring 8 is interposed between the pinion and a collar 9 on the nut. On rotation of the shaft 1, the axial movement of the nut moves the pinion into engagement with the toothed ring 11 on the engine flywheel. At the end of this axial movement, the clutch is temporarily relieved by the abutment of the pinion against a collar or shoulder 10 on the shaft 1, until frictional engagement is re-established under the influence of the spring 8.

Title: Improvements in and relating to weft stop motions of weaving looms
IPC: D03D51/20
Filed: 1929-05-17
Abstract: 312,080. Maschinenfabrik R³ti vorm. C. Honegger. May 18, 1928, [Convention date]. Stop-motions, weft.-In mechanism set in action by a central thread detector for braking and stopping the loom, a rocking member 9, Figs. 2 and 5, controlled by the thread detector is first advanced, on breakage of the thread, to operate devices for releasing the brake and then immediately to trip the stopping and starting lever to disengage the clutch, and, on its further advance, is moved into engagement with a stop whereby it is moved out of range of the part on the lay by which it was advanced. A rod 2 moving in guides 7 in the lay 3 is normally moved to the left by a spring 6 and to the right by a strap 5 secured to the breast beam 4. When the weft fails, a plate 1 is caused by the control weft detector to prevent the movement to the left by the rod 2, so that its end 8 engages the member 9 and causes it to turn a bell-crank lever 12, to which it is pivoted, into the position shown. A link 12<1> connected to one arm of the bell-crank lever operates a catch 18 for releasing the brake, and an arm 17 on the shaft of the bell-crank lever operates a link 17<1> and catch 19 for tripping the stopping and starting lever 14 for releasing the clutch. Upon further movement of the lay, an enlarged part 22 of the member 9 engages a stop 23 whereby it is turned against the action of a spring 10 into the position shown in Fig. 5 and out of the path of the end 8 of the rod 2. The catch 18 is pivoted on a cylindrical part 21, Fig. 3, pivoted to the brake lever 15 and normally engages the upper part of a plunger 20 on a rod 20<1> disposed with respect to the stopping and starting lever in the manner shown, so that the lever 15 is held raised. When the catch 18 is released, the lever 15 drops to apply the brake, and when, immediately afterwards, the lever 14 is released, the plunger 20 falls within the cylinder 21 to be again engaged by the catch 18. On moving the handle 14 in the direction shown bythe arrow in Fig. 3, the lever 15 is raised to remove the brake and the loom is re-started.
