IPC: B63B27/36
Filed: 1976-07-21
Abstract: 1511428 Heave compensating crane BRITISH COLUMBIA RESEARCH COUNCIL 21 July 1976 30373/76 Heading B8E A crane 10 mounted on the deck 11 of a ship 12 has jacks 26, 27 to compensate for the movement caused to a pulley 70 at the end of its boom 22 by the heaving of the ship so that a load suspended at the end 76 of its cable 75 can be kept stationary. An accelerometer at the end of the boom remote from its pivot to a base 18 on pins 48, 49 detects a tendency to upwards or downwards movement and by a passive control which includes a gas bladder accumulator directs fluid to or from the jacks 26, 27 to cause compensation for any movement to the end of the boom. An active control which can pump fluid to or from the jacks may be provided in parallel to the passive control and is also controlled by the accelerometer. The cable 75 is operated by upper and lower traction drums 81, 82 synchronously driven and interconnected by successive loops 84 before passing to a take-up drum 88. The two drum arrangement allows relief of the compressive loads in the winch by the upward load exerted by the boom as it tends to move. The boom 22 may be telescopic, Figs. 1, 6 its outer end 36 having a rack 104 in engagement with a gear 105 mounted on the shaft 93 of the drum 81 to which it can be clutched to move the end section 39 while correspondingly paying out or taking in the cable 75. Alternatively, the pulley 70a, Fig. 8, may be mounted on a carriage 115, movable by a screw and nut mechanism 121, 120 along a non-extensible boom 22a.

Title: Improvements in the production of cycloaliphatic alcohols and ketones by oxidation of cycloaliphatic hydrocarbons
Inventor: WALDMANN HANS JOACHIM
IPC: B01J19/24
Filed: 1958-09-24
Abstract: <PICT:0852523/IV(b)/1> In a process for producing cycloaliphatic alcohols and ketones by the oxidation of cycloaliphatic hydrocarbons, such as cyclohexane, methyl cyclohexane or cyclo-octane, in the liquid phase by means of oxygen-containing gas, in the presence or absence of a catalyst, the oxidation is carried out, at temperatures of 100 DEG  to 180 DEG C. under a pressure of 3 to 50 atm., in a series of reactors each provided with means for circulating the oxidation-mixture therein; the mixture discharged from the last reactor is washed with water and then wholly or partly decompressed; the decompressed liquid is then passed through heat-exchangers wherein it is heated by the hot compressed mixture leaving each reactor, whereby the unreacted hydrocarbon is partially vaporized from the decompressed liquid; and the unreacted hydrocarbon is finally separated by distillation from the cycloaliphatic alcohol and ketone produced by oxidation.  In the apparatus shown, there are two reactors 5 and 18.  Cyclohexane is fed through pipe 1 and heat-exchangers 2 and 3, in which it is preheated to 80 DEG C., next through gas-heated preheater 4, where it is raised to 100 DEG C., and then enters reactor 5, which is provided with an insert-tube to cause circulation.  Air and a solution of cobalt naphthenate in cyclohexane are pumped through pipe 6 into reactor 5.  A temperature of 140 DEG C. and a pressure of 25 atm. are maintained in the reactor. Oxidation-mixture, leaving the top of the reactor, is mixed with water from pipe 11 and then flows through heat-exchanger 9, wherein it gives up heat to washed, decompressed product.  The partially-cooled oxidation-mixture now flows through heat-exchanger 3, wherein it gives up further heat to the feed.  The oxidation-mixture, now at 80 DEG C. is passed into separator 13 from which the water-layer is withdrawn via pipe 15. The washed oxidation-mixture is reheated to 100 DEG C. in preheater 17, and is then introduced into reactor 18, wherein oxidation takes place in the same manner as in reactor 5.  The hot oxidation-mixture is mixed with water from pipe 11 and then passes through heat-exchanger 22, where it gives up heat to the washed, decompressed product which has already passed through heat exchanger 9.  The partiallycooled oxidation-mixture then flows through heat-exchanger 2 into separator 25.  The mixture is next mixed with fresh water, and passed to separator 30.  The washing-water, withdrawn from separator 30, is supplied to line 11.  The oxidation-mixture is next washed with 15% caustic soda solution, and finally with water again.  The washed oxidation-mixture is withdrawn from separator 36 through pipe 38, decompressed to atmospheric-pressure by valve 39, and then passed via heat-exchangers 9 and 22 to the distillation plant where the unreacted cyclohexane is separated.  Cyclohexanone and cyclohexanol are obtained by further distillation.  Specification 815,162 is referred to.

Convention date, Oct. 30, 1928. [Class 97 (iii).] In the system for the detection of foreign matter in fluids, for example, smoke in air, in which light is reflected and/or refracted on to a light-sensitive cell by the foreign matter when present in a stream of the fluid, the cell is permanently exposed to a small beam of light, so that a small supervisory current flows in the alarm circuit, which includes a no-load relay. As shown, smoke present in a stream of air passing across a light beam c<1> will illuminate the photo-electric cell e to cause an alarm to be given. A mirror g is associated with the light source c so that a small beam c<5> permanently illuminates the cell e. In a modification, a separate light source directs the beam upon the cell. The cell is in circuit with a battery i, no-load relay l, overload relay l<1>, and thermionic amplifier j. The constant light beam c<5> causes a supervisory current to flow in the circuit insufficient to operate the relay l<1> and sufficient to prevent operation of the relay l. Smoke in the light beam c<1> increases the current, operating the relay l<1> and an alarm m<1>. Failure of the apparatus from any cause interrupts the supervisory current, causing operation of the no-load relay l and an alarm m.

Filter aid such as ash from a bunker 2 is first dosed at 1 into a water tank 3. Filtrate from the reservoir 5 of a filter press 22 is pumped (4) into the tank via conduit 6 after ash feed has ceased. Eventually the rising liquid acts on floats 10 to close ash pipe 9 by flap 8. Thereafter, liquid flowing out at 11 into a vessel 15 contacts an electrode 13 to effect switching off of pump 4 and closure of valve 12. These stages occur during a filtration stage in the press 22. When a new filtration stage is about to start, and a manometer in the press closure hydraulic circuit indicates that the closure pressure has been reached, a control elements effects opening of a valve 17 in a conduit 20 leading from a compressed air reservoir 27 to jets 19 in tank 3. Filter aid suspension is thereby forced up a conduit 23 past a check valve 24 and into the sludge inlet conduit 21 of the press, so as to be discharged on to the filter medium at a speed of flow corresponding to a multiple of the sedimentation speed of the filter aid. Valve 17 is then closed and sludge is fed to the press.
