Abstract: A railway vehicle for urban use has at least one motorized truck and at least one non-motorized supporting truck. The supporting truck is provided with wheels of smaller diameter than the wheels of the motorized truck which enables a lowering of all of the floor area of the vehicle except the portion which lies above the motorized truck. This lowering of the floor permits the use of a single intermediate step to be utilized by passengers and expedites their entry into and exit from the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE:       METHOD AND APPARATUS FOR REDUCING EXCESS AIR       INLEAKAGE INTO AN OPEN RING-TYPE CARBON                  BAKING FURNACE     A method for reducing excessive air inleakage and fuel consumption in open ring-type carbon baking furnaces is disclosed. This method consists in covering the pre-heat sections of the fire with covers. Each cover is preferably mounted on legs and a flexible sealing skirt is located all around to accommodate the height vari-ations across each furnace section. There are usually more than one preheat section and the covers are iden-tical in construction and dimension to minimize move-ment of the covers when the fire progresses. To further reduce fuel consumption, covers can also be placed on some of the cooling sections behind the fuel-fired sections and air can be blown or sucked into these sections to force cool these sections and to provide preheated air for combustion in the fuel-fired sections.

Abstract: SEMICONDUCTOR BODY AND LONG-LIVED LIGHT EMITTING DEVICE THEREON ABSTRACT OF THE DISCLOSURE An improved semiconductor body upon which a light emitting device can be fabricated where the improvement is a barrier layer, which has a lattice constant different from that of the substrate and buffer layer, interposed between the substrate and the buffer layer. The strain associated with the lattice constant mismatch is believed to provide a trap for defects which migrate out of the substrate into the active region of the light emitting device. Accelerated life tests at 90°C show a significant reduction in the rate of degradation of the spontaneous light output power of light emitting devices incorporating the invention.

Abstract: ABSTRACT              INTERESTERIFICATION PROCESS AND APPARATUS AND PRODUCTS THEREFROM     The process is a continuous process and comprises bringing together streams comprising a triglyceride oil and a catalyst solution of water, sodium hydroxide and glycerine respectively, homogenising the mixture, reducing its water content, and interesterifying.    Preferably the homogenisation and drying steps take place consecutively and are combined and are performed by passage through a spray drying nozzle.  The efficiency of the homogenisation and drying steps allows the interestifying step to take place in about 4 minutes and thus permit operation of the process in a continuous manner.

Abstract: ABSTRACT      A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency.  The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other.  It may be used, with the protected side innermost, for unit packaging of detergent compositions, especially liquids containing bleach.  In use in the washing machine, the unprotected surface is attacked by the wash liquor to release the contents;  the protective layer prevents attack of the package by the contents during storage.

Abstract: ABSTRACT        Vehicle for deicing aircraft.         A vehicle for deicing aircraft comprises an under-carriage (1) having a lifting device (4,5,6,7) carrying a closed operation cabin (3). The vehicle includes a spray device for applying spray fluid to the aircraft, and this spray device comprises a pump and a connected spray nozzle. To avoid frequent adjustments of the position of the carriage and to allow spray operations close to the areas to be spray-ed, the spray nozzle is supported on a longitudinally ad-justable lightweight boom (20) carried by the cabin (3). The cabin (3) is further pivotally supported by means of a turntable construction (15,16) relative to the carriage (1). The nozzle is also connected to remote control means in the cabin (3) for pivotal movement of the nozzle about two axes extending perpendicular to each other. The two pivot axes are appropriately intersecting in a point coinciding with the direction of the jet from the nozzle.            Figure 1.

Abstract: A MATCHING AND ISOLATING DEVICE COMPRISING A FERRITE CIRCULATOR     ABSTRACT     A ferrite circulator is placed between a circuit to be matched and a connection point for performing the function of a directional isolator.  In order to achieve matching of the circuit to be matched without any need to add a matching circuit of the parallel resonant type, advantage is taken of the fact that the access impedances of a ferrite circulator are comparable with those of parallel resonant circuits.  The choice of the circulator is accordingly governed by the need to ensure that the impedance of its access which is coupled to the circuit to be matched corresponds as nearly as possible to the conjugate impedance of the circuit to be matched.  If necessary, an impedance transformer such as a quarter-wave transformer which is not provided with a parallel resonant element can be inserted between the circuit to be matched and the circulator.

Abstract: ABSTRACT OF THE DISCLOSURE                 FUEL OIL INJECTION ENGINE   The  circulatory  fuel  oil  injection  supply  system of  a  diesel engine is adapted so that the engine may be run selectively either in a single fuel mode on diesel oil alone or in a dual-fuel mode on both diesel oil and gas. The control system and fuel system of the engine are modified so that  pressure conditions at a diesel oil  injection metering device during the single fuel mode are mimicked by a first flow restrictor during the dual-fuel mode.  A pressure sensor measures the mimicked pressure and controls the amount of gas flow to the engine via an electronic  programmable  control.   A shut-off  first  solenoid valve operative in the single fuel mode circuit is by-passed in the dual-fuel mode while second and third solenoid valves are operative to open a by-pass line including a second flow-restrictor and to open a reference pressure supply line respectively.  A governor control and a throttle control having a by-pass weep line remain operative in both the  single  fuel  mode  and  in  the  dual-fuel mode.    In  a  further modification the first flow-restrictor and third solenoid valve and the second flow-restrictor and the second solenoid valve are replaced by respective pulsed solenoid valves providing variable flow-restrictors so  as  to allow a variable amount  of  pilot  diesel  fuel  oil  to be supplied in the dual-fuel mode via the electronic control.

The process is characterised in that the SO2-containing gas produced by combustion is cooled to a regeneration temperature or cooling temperature and conducted through the second catalyst stage charged with sulphur or respectively freed from sulphur and thereby regenerates or cools the said stage, the sulphur taken up in the regeneration phase is condensed out and separated from the SO2-containing gas, after being combined with the tail gas, is conducted through the first catalyst stage for the formation and separation of sulphur.  The process permits a flexible control of the temperature of the regenerating gas, corresponding to the regeneration and cooling phases.
