Title: Process for substantially suppressing phosgene-formation when extinguishing fires with carbon tetrachloride
IPC: A62D1/00
Filed: 1929-08-19
Abstract: 319,320. I. G. Farbenindustrie Akt.- Ges. Sept. 20, 1928, [Convention date]. Chemicals. - The known process wherein ammonia and a hydrocarbon are added to carbon tetrachloride to suppress the formation of phosgene when the carbon tetrachloride is used for extinguishing fires is modified in that aryl or alkyl phosphates, or mixtures thereof, are added in place of the hydrocarbon. Alternatively, the phosphates may be added as well as the hydrocarbon. A very small amount of ammonia may be used, or sufficient to serve as a propelling agent for the extinguishing liquid. In the former case, compressed air or nitrogen may be used as the propelling agent. Amongst examples given of suitable additions to the carbon tetrachloride are the following : ammonia and three per cent of tricresylphosphate; ammonia, two per cent of petroleum, and one per cent of tricresylphosphate.
Patent GB-684239-A (GB)
Title: Improved method and means for the operation of change speed gearing
Filed: 1949-09-30
Abstract: 684,239. Change-speed gearing; operating clutches. NALLINGER, F. Sept. 30, 1949 [Nov. 19, 1948], No. 25263. Class 80 (ii). The main clutch of a motor vehicle, arranged either ahead of or behind the change-speed gear, is automatically partially relieved during a gear change, the degree of relief depending on the position of the gear control means or on the torque being transmitted. In the arrangement shown in Fig. 1, a gear lever c operates in a gate d, each branch of which has a pair of electric contacts such that an electromagnetic main clutch e is fully engaged when any gear is engaged, while, as the lever c is moved towards neutral position, a resistance l is brought into the circuit, so as partially to relieve the clutch e prior to actual disengagement of the gear, and, as the lever reaches neutral, the circuit is broken. The resistances l vary for the various gear positions, being smallest for top gear and largest for reverse or first speed. A pedal f controls a variable resistance i, so that by depression of the pedal the clutch can be partially or completely relieved at will. As shown in Fig. 3, where gear changes are made by hydraulic means (not shown) under the control of a rotary valve 5, the latter also controls supply of pressure oil to a cylinder z, the piston z' of which controls the main spring-engaged clutch e and which exhausts via the valve 5 and one of a series of restrictions 9 which vary for the particular gears. If, for example, the valve 5 is moved clockwise towards second gear position from the position shown, in which first gear is engaged, the valve first allows pressure oil to pass to the cylinder. Due to the restricted outlet, pressure builds up in the cylinder and the piston moves to relieve the clutch to an extent depending on the restriction associated with the first gear, which latter now disengages. As the valve continues to move, oil is still supplied to the cylinder but the latter now exhausts through the restriction associated with second speed, so that the degree of clutch relief is varied. Second speed now engages, and finally valve 5 cuts off supply of oil to the cylinder and the clutch is fully engaged. In the form shown in Fig. 2, wherein gear changes are controlled by a rotary arm m, the latter, in moving out of any gear position, completes an electric circuit including a solenoid q and a variable resistance p controlled by a torque-responsive spring coupling n arranged between the main spring- engaged clutch e and the gear, the armature of the solenoid acting to relieve the clutch e to a degree depending on the torque. The armature also acts through a link t to reduce the fuel supply to the engine.

Title: Improvements in or relating to aerial systems
IPC: H01Q3/18
Filed: 1956-08-17
Abstract: 809,751. Aerials. GENERAL ELECTRIC CO. Ltd., FARMER, E. D., and McCONALOGUE, D. J. Aug. 13, 1957 [Aug. 17, 1956], No. 25284/56. Class 40 (7). A radar aerial system for producing a conical scan is so designed that the inequality in the side lobes of the polar diagram arising from the asymmetry of the system is, at least partially, eliminated. Fig. 2 shows a portion of one embodiment of the system: a rectangular feeder waveguide 8 lies on the axis of symmetry of a paraboloidal reflector, of which only a small portion is shown, and has a further length of guide 9 which is uniformly tapered and has its axis offset from the main axis by a small angle. A member 11 is mounted in the mouth of this latter piece of guide, being soldered to it and having its plane parallel to the axis of the guide 9 and/or shaped as at 14. Two dipole aerials 6, 7 are mounted with their axes perpendicular to the plane of the member 11 and on the axis of the guide 9. Because of the positioning and/or shape of the member 11 there is unequal coupling between the two halves of the dipoles and the guide 9 so that the side lobes of the polar diagram are brought nearer to equality. A circular hole in the reflector, with its centre on the axis of the reflector, is partially filled with a circular member 23 which is secured to the guide 8 and has a reflecting surface 24. In order to prevent multiple transmissions, due to energy being reflected from the reflector to the dipoles, a small reflector 25 is provided in known manner. It is circular in shape embracing the guide 8 and having a reflecting surface 26. To obtain a conical scan the guide 8 is caused to rotate about its axis by means of a motor and gearing, Fig. 1 (not shown), the arrangement being such that the dipoles describe a circle about that axis in the region of the focus of the reflector.

A beam 31 scans in plane 20 by sinusoidal variation in phase over 180 degrees in the controlled phase shifters which may be of the kind employing a ferrite cylinder (see Division H1). In another embodiment the aerial system is a circular array of waveguides, selected ones only being excited at any instant, Fig. 5 (not shown). Omnidirectional radiation may be arranged. Aerial elements may be grouped in pairs 160, 168 &c., Fig. 6, and are fed via ferrite circulator switches a 1  . . . a 4 , b 1  . . . b 4 , c 1 ... c 4 ; when a coil, e.g. 200 is energized by a positive pulse the input to the respective switch goes to the upper line therefrom and when energized by a negative pulse, to the lower line.

In a fuse-link of the cartride type, in which a fusible element 11 extends from one end of a hollow body portion 10 and retains an indicator plunger 20 in the unoperated position against the force exerted by a compression spring 19, a rubber diaphragm 14, clamped to the said end of the body 10 by a cap 15, exerts radial pressure on the periphery of the element 11 where the element pierces the diaphragm, thereby preventing the escape of a quartz sand filler from the body 10 yet permitting the movement of the element 11 relative to the diaphragm to release the indicator plunger 20 when the fuse blows. The indicator plunger may be arranged to operate a micro-switch. In assembling the fuse-link, the element 11 is forced through the rubber diaphragm 14 to pierce it.

The partition is of natural or synthetic rubber and formed with a bead 71 which is clamped between the shaped ends of the members 66, 67 by a nut 77 and a block 78 on the rod 73. A passage 89 in the end of the rod provides a gas port leading to one side of the partition, and a threaded bore 79 and a passage 95 in the block 78 provide a liquid port leading to the other side of the partition. A plate 101 of sintered material, such as bronze, and a disc 104 of resilient material, such as natural or synthetic rubber, having perforations 105 are secured between a shoulder on the rod and the member 66.
