Patent FI-892954-A (FI)
IPC: E01C/
Filed: 1989-06-16
Abstract: The invention concerns a method of thawing out frozen soil in a field provided with a sub-surface piping system 2,3 for drying out the field and for guiding air through the field; also equipment for leading the heated air to the piping system 2,3. The object of the invention is to produce a new method of thawing frozen soil in a field, thereby bringing it more rapidly back into use. According to the invention, the flow of air begins either through the ground, or through the pipe system to the valves 12 situated at the ends of the pipes, and continues out into the open air whereby the thaw begins. After that, the blasts of air continue periodically so that, during the intervals, the meltwater flows through the pipe system 2,3 and on to the drainage wells 11. <IMAGE>

Abstract: Self-reinforced silicon nitride ceramic bodies of high fracture toughness are prepared by hot-pressing a powder mixture containing silicon nitride and three other components under conditions such that densification and the in situ formation of  beta -silicon nitride whiskers having a high aspect ratio occur. The other components are silicon dioxide as a densification aid, a conversion aid such as yttrium oxide and a compound, such as calcium oxide, which enhances growth of  beta -silicon nitride whiskers. The resultant silicon nitride ceramic has a  beta -silicon nitride crystalline phase, at least 20 volume percent of which is in the form of whiskers or elongate grains having an average aspect ratio of at least 2.5, and a glassy second phase. The glassy phase contains the silicon dioxide, the conversion aid and the compound which enhances growth of  beta -silicon nitride whiskers. The glassy phase may also include a minor amount of aluminum nitride or boron nitride.

Date Nov. 26, 1992.The invention provides a method of, and apparatus for detecting and analyzing moving particles using an impact responsive transducer which generates a detection signal having an amplitude related to force of particle impact. The transducer output signal is monitored and when it exceeds a given threshold, any local maximum values are noted. Those values are compared to determine which has the overall maximum amplitude. A final signal is then generated in order to provide a representation of the maximum value, and hence the momentum and time occurrence of a particle impact.

Abstract: The powder-actuated driving tool has a piston return mechanism operating through the use of compressed propellant gases. For this purpose, propellant gases pass from an opening (6) via a passage (5) through an opening (7) into the guide bore (2a) of a piston guide (2). The piston (1) is driven by the compressed propellant gases from its front end position into its rear initial position until it comes to bear on the base (4c) of a cartridge carrier (4). While the piston (1) comes to a stop, the cartridge carrier (4) is displaced to a limited extent against the driving direction. For this purpose, the cartridge carrier (4) is connected to a housing part (3) via a buttress thread (3a, 4a) exhibiting backlash. <IMAGE>

Apparatus, for winding a pneumatic tyre carcase reinforcement of the type in which a cord is wound on the surface of a former in zig-zag fashion from one side of the reinforcement to the other, comprises a rotatable former 1 disposed within an annular track 8 with its rotational axis 2 set obliquely to the circumferential plane of the track and intersected at right angles at the geometric centre of the former by one diametral axis 5 of the track, and a carriage 16 mounting a cord guide 19 drivable around the track during rotation of the former to provide a progressive cord winding of slightly displaced convolutions distributed evenly around the former surface. As shown the track 8 is provided on the inner periphery of an annular housing 3 which is mounted on a shaft 4 journalled vertically in a casing 6 beneath the housing and extending in alignment with the diametral axis 5. A ring 9, on which the carriage 16 is rigidly mounted, is rotatably supported in the track 8 on rollers 10, and is provided with a radial face 11 formed with bevel gear teeth 12 which are drivingly engaged by a bevel pinion 13 on a shaft 14 rotatably mounted in the housing 3. The shaft 14 is driven for rotation of the ring 9, and thereby the carriage 16, by a shaft and gearing 15 connected to the driving motor of the former 1. Rotation or oscillation of the housing 3 about the axis 5 to vary the angle of inclination with the former 1, and thereby adjust the width or lay of the winding, is effected by rotation of a motor-driven cam 35 having a cam groove 36 driving a follower 34 which is attached to a rack 29. The rack 29 rotates a pinion 32 which is drivingly connected, by a sprocket 30 and chain 31, with a sprocket 28 rigid with the housing 3. A spool 24 storing the cord 37 is supported between two arms 23 extending from the housing 3, the cord 37 being fed from the spool over a free pulley 25 which is mounted on the inner race of a bearing supported between the arms 3 coaxial with the axis of rotation of the carriage 16. The cord 37 passes around an idling pulley 22, which is mounted on the carriage 16 with its axis parallel to the axis 5, and thence around a guide pulley 19 which is disposed at right angles to the pulley 22 and is spring-urged into contact with the surface of the former 1. In modified constructions the cam 35 may be driven by the former motor, and the former may have a spherical, crowned, or cylindrical winding surface. Alternatively, the rack 29 may be operated by an hydraulic piston and cylinder mechanism and the carriage 16 may be attached to a pair of parallel endless driving chains supported on idling sprockets in place of the ring 9. Specification 808,341 is referred to. Reference has been directed by the Comptroller to Specification 786,162.

[Also in Group XXIX] A fluid-pressure servomotor control system for controlling the fuel supply to a plurality of I.C. engines, e.g. a pair of marine diesel engines, so that they apply cumulative and equal torques to a common propeller shaft, includes for each engine a fuel regulating valve 5(6), Fig. 3, having first and second diaphragms 21, 22 positioning a spring-loaded valve member 27 controlling the flow of operating fluid between pipes 20 and 7(8) connected respectively to a compressed air source 1, Fig. 2, and, e.g. a fuel injection pump, 9(10) to regulate the latter and hence the fuel supply to an engine 11(12) which through spur gearing 15, 17, is connected to a common propeller shaft 18. The diaphragm 21 which is adjustably loaded by a spring 34 has its operational area also adjustable by means of a collar member 24 screw-threadedly attached to a spindle 25 connecting the diaphragms together. The diaphragm 21 is subjected on its upper face to a control pressure predetermined by the settitng of a manuallyoperable control valve 3 connected to the source 1. When the control pressure overcomes the loading of a spring 33 acting on the diaphragm 22 and the pressure in a chamber 37 beneath this diaphragm, the valve member 27 is unseated to increase the supply of compressed air operating the fuel injection pump to increase the fuel supply to the engine. When the pressure in the chamber 37 plus the loading of the spring 33 is greater than the control pressure the valve 27 first becomes seated and then any further increase in the chamber 37 moves the diaphragm 21, 22 upwardly to connect the chamber 37 to atmosphere through a passage 30 and opening 32, to reduce the fuel supply to the engine. The loading on and the operational area of each diaphragm 21 may be independently adjusted. Adjustment of the spring loading adjusts the zero control pressure point and adjustment of the operational area the slope of the torquecontrol pressure curve.
